Adrienne Rich on Power in Society

Adrienne Rich on power in society Introduction The theme that interested me most in the poems by Adrienne Rich was the inadequacy of language as a means of communication. Rich shows that the reason for this lies in the way language expresses power relationships in society. Often this means the unequal relationship between women and men, but also between the powerful and the powerless. This theme is touched upon in almost every poem we studied, from Rich’s early poems to those written later. To illustrate how Rich explores this theme I will look in detail at â€Å"Aunt Jennifer’s Tigers†, â€Å"The Uncle Speaks in the Drawing Room†, â€Å"Our Whole Life†.Paragraph 1 In â€Å"Aunt Jennifer’s Tigers†, Rich creates a fantastic image of the aunt’s nonverbal communication through her tapestry. The poem opens with a vivid picture of the colourful, energetic alive world depicted on the tapestry. The aunt infuses the world of the tigers with many of the attributes she misses in her own life: a sense of being truly alive and in tune with the environment, and a state of fearlessness: â€Å"They do not fear the men beneath the tree/ They pace in sleek chivalric certainty. The ee- sound in these lines introduces a note of terror that heralds what is to come. Indeed the phrasing suggests a reason for fear from men. The feelings that the aunt is projecting into her artwork, her own fears and desires are developed in the middle stanza. Her shaking, fearful hands â€Å"fingers fluttering† are very vivid and the fact that they find the â€Å"needle hard to pull† suggests physical weakness and contrasts very much with the tigers. Paragraph 2 The reason for this weakness is â€Å"Uncle’s wedding band/ Sits heavily† on her â€Å"hand†.The possessive â€Å"Uncle’s† suggests that this is a one-way marriage that drains all life out of the aunt. Her hands come to represent her pers on in this poem and it is the hands that do the ‘talking’. The Uncle’s power over her seems to continue in death â€Å"When Aunt is dead, her terrified hands will lie/ Still ringed with the ordeals she was mastered by. † However, her unspoken, yet very articulate legacy remains: â€Å"The tigers in the panel that she made/ Will go on prancing, proud and unafraid. The tigers represent happiness, confidence and thereby beauty. Interestingly, this image of self-determination and sense of entitlement to the world is projected into the jungle, i. e. outside of society. This is where freedom exists and Aunt’s art gives expression to this. Paragraph 3 In contrast to Aunt Jennifer’s indirect communication, â€Å"The Uncle Speaks in the Drawing Room† is the dramatic monologue of a wealthy, powerful man. He speaks as a representative of the ruling class looking out at a group of discontent working people.These people have neither wealth nor pow er. They have gathered outside his big house to express their anger at this inequality. The uncle’s attempt to convey confidence and reassurance to his family is undermined by the images of anger outside. The poem’s sound expresses this threat. O- sounds and S-sounds dominate: â€Å"Standing sullen in the square [†¦] Some have held and fingered stones. † As the poem develops, the Uncle’s own fear becomes clear. The image of â€Å"glass† echoes and comes to symbolise â€Å"class†.He admits that the â€Å"frailties of glass [†¦] Lead in times like these to fear/ For crystal vase and chandelier. † Even his reassurance â€Å"None as yet dare lift an arm† achieves the opposite – the suggestion of an uncertain future, â€Å"arm† in fact has two meanings in this context! Paragraph 4 In fact the two most vivid images in the poem are the angry crowd outdoors on the one hand and the terrified forefather (indoors à ¢â‚¬â€œ like this family) on the other: â€Å"When our grandsire stood aghast/ To see his antique ruby bowl/ Shivered in a thunder-roll. Despite his attempts to reassure, the Uncle admits to deep unease at the end of the poem regarding the precarious position of his class as â€Å"We stand between the dead glass-blowers/ And murmurings of missile-throwers. † In terms of the theme of language, the Uncle uses it to express his position as a powerful wealthy man. Although his fears still become clear, it is still a useful tool for him. The workers outside do not have a voice, their language is not verbal: â€Å"sullen stares†, â€Å"bitter tones† and holding â€Å"stones†. There is no common language between the powerful and the powerless.Paragraph 5 â€Å"Our Whole Life† was written later. There is a stark change in terms of form to the previous two poems. It is written in free verse and uses no punctuation whatever. This in itself indicates Richâ⠂¬â„¢s thinking about language and the ability to express truth. Here, she strips it of its traditional appearance. In terms of theme, â€Å"Our Whole Life† explores the shocking gulf between the powerful and the powerless at a new level. Language has failed the powerless completely. Language is used to manipulate people’s thoughts about the world, â€Å"rendered into the oppressor’s language†.In an incredibly vivid image Rich depicts language as a violent and self-destructive wild animal: â€Å"and now a knot of lies/ eating at itself to get undone/ Words bitten thru words†. The biting and eating is enacted in the abbreviated spelling â€Å"thru†. People’s actual lives and experience cannot be told: â€Å"meanings burnt-off like paint/ under the blowtorch/ All those dead letters/ rendered into the oppressor’s language†. Paragraph 6 This poem places one shocking image after the other and language has become an instrument in a very violent world.The vision goes much further than in â€Å"The Uncle Speaks†, it encompasses the whole world and is in essence apocalyptic. The image of the burning Algerian walking away from his village to a doctor with no words to describe is pain is haunting: â€Å"his whole body a cloud of pain/ and there are no words for this/ except himself†. The absence of punctuation and in particular of a concluding full stop suggests the ongoing nature of the problem. Language has completely and disastrously failed its purpose as a means of communication between humans.In conclusion, Rich has opened up for me a way of looking at language that in some ways coincides with my own thinking and experience. However, she takes it unflinchingly and with amazing honesty and courage to a final analysis. She creates in her poetry unforgettable images for how women and all the powerless have been deprived of a means of expressing themselves. Language is an instrument of the powe rful. Although Rich’s poetry is a reflection of radical feminism and political struggle in the USA during the 6os and 70s I feel that what if conveys is as true now as it was then.

Political Risks in International Marketing

Assessing the political environment is an important part in any business decision. Laws and regulations passed by either local, regional and central government bodies can affect foreign firms' operations. Also, firms are comfortable assessing the political climates in their home countries. However, assessing the political climates in other countries is still problematic. Classification and description of political risks When doing international business, the manager may face several types of financial risks.The major types of financial risks are commercial risks, political risks, exchange rate risks, and other such as inflation-related risks. Thus, political risks are non commercial risks. Political risks are any changes in the political environment that may adversely affect the value of a firm's business activities. Political risks may occur in any nation, but the risks vary considerably between countries. We may distinguish two types of classification of political risks. A classifi cation based on the characteristic of political risks and a classification or categorization based on the local government actions or control.Classification based on the characteristics of political risks Characteristics refer to as the facts that are inherent to each political risk. In other terms, their uniqueness or what make them different from one another. There are three types of such characteristics: ownership risks, operating risks, and transfer risks. Ownership risk In which the property of the firm is threatened through expropriation, confiscation or domestication. Ownership risk exposes property and life. The triad will be explained in the second classification. Operating risk  In which there is interference with the firm operations.The ongoing operations of the and/or the safety of its employees are threatened through changes in laws, environmental standards, tax codes, terrorism, armed insurrection or wars, and so forth. Transfer risk  In which the government interf eres with a firm's ability to shift funds into and out of the country. Classification based host country actions We can distinguish two types: political risks out of the government control and political risk induced by the government. Political risks out of government control. There are risks or events arise from nongovernmental actions, factors that are outside the government responsibility.There are  wars, revolution, coup d'etat, terrorism, strikes, extortion, and kidnappings. They all derived from some unstable social situation, with population frustration and intolerance. All these risks can generate violence, directed towards firms' property and employees. We may also have the case of  externally induced financial constraints and externally imposed limits on imports or exports, especially in case of embargoes or any economic sanctions against the host country. Political risks induced by the government These risks constitute some laws directed against foreign firms. Some go vernment-induced risks are very drastic.There are expropriation, confiscation and domestication. Expropriation  is the seizure of foreign assets by a government with payment of compensation to the owners. In other terms, it is involuntary transfer of property, with compensation, from a privately owned firm to a host country government. Expropriation may generate some funds for the owners. However, procedures to get paid from the government are sometimes protracted and the final amount remains low. Furthermore, if no compensation is paid, conflicts may erupt between the host country and the country of the expropriated firm.For instance, the relations between U. S. and Cuba acknowledge such situation, since Cuba does not offer compensation to U. S. firms that have their assets sized. 3(*)  Also, expropriation can refrain other companies from investing in the concerned country. Confiscation  is another type of ownership risk similar to expropriation, except compensation. It is in voluntary transfer of property, no compensation, from a privately owned firm to a host country government. In confiscation, firms do not receive any funds from government. Thereby, it represents a more risky situation for foreign firms.Some industries are more vulnerable to confiscation than others because of their importance to the host countries and their lack of ability to shift operations. Sectors such as mining, energy, public utilities, and banking have been targets of such government actions. Domestication  offers to governments a subtle control over the foreign investments. There is a partial ownership transfer and companies are urged to prioritize local production and to retain a large share of the profit within the country. Domestication can negatively impact the international marketer activities, as well as that of the entire firm.For example, if foreign companies are forced to hire nationals as managers, poor cooperation and communication can result. If domestication w as imposed within a short time span, poorly trained and inexperienced local managers would head the firm operations with possible lost of profits. Other government actions-related risks  are less dangerous but more common such as  boycott, sabotage. When facing shortage of foreign currency, government, sometimes, attempts to  control the movement of capital  in and out of the country. Often,  exchange controls  are levied selectively against certain products or companies.Exchange controls limit importation of goods so that firms might be confronted with difficulties in their regular transactions. Severe restrictions on import  can be a motive for foreign corporate to shut down. Governments may also raise the tax rate applied to foreign investors in order to control them and their capital. Government may implement a  price control system. Such control uses to derive from a sensitive political situation. For example, social pressure may result in a kind of price standa rdization for particular sectors like food, transportation, fuel, and healthcare.Political risks like arms conflicts, insurrection may affect all firms in the country equally. For that reason they are called  macro political risks. Unlike, nationalization, strikes, expropriation may affect only a handful and specific firm, they are named  micro political risks. Impact of some political risks Some negative effects of political risks on firm are summarized in the following table. Table 1. Holistic table summarizing the major political risks and their effects on firms TYPES| IMPACT ON FIRMS| Expropriation| Loss of future profits| | | Confiscation| Loss of assets| Loss of future profits| | | Campaigns against foreign goods| Loss of sales| | Increased costs of public relations efforts to improve public image| | | Mandatory labor benefits legislation| Increased operating costs| | | Kidnappings, terrorists threats, and other forms of violence| Disrupted production| | Increased security costs| | Increased managerial costs| | Lower productivity| | | Civil wars| Destruction of property| | Lost sales| | Disruption of production| | Increased security costs| | Lower productivity| | | Inflation| Higher operating costs| | Repatriation| Inability to transfer funds freely| | | Currency devaluations| Reduced value of repatriated earnings| | | Increased taxation| Lower after-tax profits| | | Source, Ricky W. Griffin, International business, 2005, page 73 In long run, and depending on the severity of the risks, action taken by government may decrease income and be detrimental to the host country economy. Strong political risks that are deeply rooted in the country governance habit might be barriers to foreign investment and country prosperity. What is going on in West Africa?

News Media use and political Communication - you have to analyse a Essay

News Media use and political Communication - you have to analyse a paper that I am attaching - Essay Example The study aims to prove the importance of studying mediation in the study of the relationship between media and polities. A wide variety of literature ranging from Holbert & Stephenson 2003, Lazarsfeld, Berelsen & Gaudet 1948, McLeod, Kosicki, and McLeod 2002 are mentioned to show how intra-media mediation is overlooked in the traditional study of political communication and media. The writer finds the importance of his study in the fact that other studies in the same field have not taken intra-media mediation into consideration. The previous studies largely overlooked the fact that the relationships among various forms of media may enable media to function as mediators of each other. In fact, the study is an extension of the O-S-O-R model of media as the basis for the media-related political communication. However, this new work presents an O-S-S-R framework which allows one set of stimuli to influence another set of stimuli, thus taking the intra-media mediation into consideration. The benefit of this framework is that it can be expanded to include the multiple stages of variables located in between the two sets of stimuli and after the latter stimuli. The study is based on the assumption that the best predictor of a given type of media use at a later time is its use at a previous time. So, the research has its hypotheses to show the cumulative nature of media use. The first two hypotheses can be summarized as follows: Television/newspaper use at former time positively influences television/newspaper use at later time. Now taking into consideration the fact that the use of one form of media can lead to the use of other forms of media too, the third and fourth hypotheses take birth: television use at a former time positively influences newspaper use at a later time, and newspaper use at a former time positively influences television use at a later time. Another point of consideration is the fact that at the heart of presidential election campaign, increased kn owledge will be available through media about endorsement. So, the fifth and sixth hypotheses are: television news at a later time influences candidate endorsement knowledge, and newspaper use at a later time positively influences candidate endorsement knowledge. Now, to show the intra-media relationships, a combination of hypothesis are used: television news at a later time serves as a mediator in the relationship between television use at a former time and candidate endorsement knowledge, and newspaper use at a later time serves as a mediator in the relationship between newspaper use at a former time and candidate endorsement knowledge. In addition, television news at a later time serves as a mediator in the relationship between newspaper use at a former time and candidate endorsement knowledge, and newspaper use at a later time serves as a mediator in the relationship between television use at a former time and candidate endorsement knowledge. As a part of the study, the informat ion was collected in two phases. The first phase (the former time) was from July 21 to August 13, 2000 and the second phase (the later time) was from October 18 to October 31, 2000. The first phase was before the Gore-Bush debate of October 17 and the second phase was after Gore-Bush debate, or at the heart of the election campaign. The questions asked were related to the audience’

Uncooperative Witness & Collection of Evidence Assignment

Uncooperative Witness & Collection of Evidence - Assignment Example Given such circumstances the investigator has to find ways and means of convincing that witness to agree or find another way to collect the required evidence. Introduction The process of collecting evidence to be used in the prosecution of an offender usually involves collecting evidence from witnesses. Witness accounts are usually by far the best type of evidence in criminal cases as a god truthful witness can be most convincing at a trial. However, when witnesses choose to be uncooperative due to fear or any other type of misgivings, it may make it hard for a prosecution to be successful and may even result in the acquittal of a guilty person or the throwing out of the case on a technicality. It is the investigators’ work to ensure that they get the most reliable and believable witnesses but it is also important that the witness be willing and able to testify in a court of law when called upon to do so. It is therefore the work of the investigator and the prosecution in prep aring witnesses for court and also ensuring that their testimony is availed to the judge and jury in the most efficient manner. 1. The investigator’s work is to ensure that all the evidence is presented to a court of law in a way that makes it possible for the correct finding to be made based on facts and evidence presented. One of the prime duties in accomplishing this is the finding, interviewing and preparing of witnesses that will be able to give useful evidence at trial (Shirreff, 2011). This process can be hampered when a witness is reluctant or uncooperative because of what they may perceive as negative impacts of their testifying at a particular trial. The investigator therefore needs to be very careful in their handling of the witnesses by clearly explaining to them the reasons why their evidence is required. The evidence that the witnesses give needs to be handled in a manner that ensures that it is not contaminated either by being influenced by that of other witnes ses in the same trial (Bertino, 2011). It is important that the investigator familiarizes himself or herself with the situation of the witness and that all the circumstances in which they have to testify. This needs to be clarified ducting the interview process and be recorded as such to ensure that the witness knows that the investigator is fully aware of what the witness thinks will be the impact of their testimony on himself and others. Such collection of evidence in an orderly and calm composed manner also ensures that the witness feels safe and secure in the trial. It is important the investigator also makes the witness aware of any danger that they may be placing themselves in by testifying and also, more importantly, the remedies that are available in law to mitigate this. One of the paramount duties of the investigator is to protect the integrity of all their evidence including the evidence that is given by the witnesses and in this case it means protecting the witness thems elves (Bertino, 2011). 2. There are some ways in which an investigator can ensure that an important witness co-operates with the investigation. One of the most important ways is to reassure the witness that the impact of their evidence is to get the right person imprisoned and also where

Business enviroment - ECONOMICS Essay Example | Topics and Well Written Essays - 1500 words

Business enviroment - ECONOMICS - Essay Example The UK construction industry has witnessed a fall of nearly two percent in construction activity during 2010 compared with last years 12 per cent drop and is expected to remain in recession. It is estimated that by the end of 2010, construction industry will have lost  £16 billion of work in just three years and the growth is not expected to return until 2011 and even then it is forecasted to be relatively subdued at just one per cent per year in the consecutive three years coming. An interesting factor to be observed here is regarding the private Vs public construction companies’ progress. Over the past one and half year, private sector construction fell by almost 20 percent, losing approximately  £14bn of work and a further fall of four per cent is anticipated during 2010. However, the public sector construction, on the other hand, rose due to government’s fiscal stimulus and contractors on government frameworks were able to take advantage of some of the falls experienced from the private sector. There are high chances that this trend is set to reverse in the near term as a result of economic recovery set to lead to a rise in construction funded by the private sector. On the other hand, the state of the public finances is likely to lead to a deep fall in public spending on construction. Critical fact lies in spending on public schools and housing, as well as on energy and transport infrastructure and they are not cut sharply, otherwise recovery for the construction industry might be delayed and consequently, the economic recovery in the UK might be severely hindered. 1. With some new contracts signed, in addition to existing work brought forward through governments fiscal stimulus, orders rose 60 per cent during 2009 and although the number of roads projects signed in the last first quarter of 2010 has remained broadly flat compared to

Critically evaluate current neo-liberal education policies, in Essay

Critically evaluate current neo-liberal education policies, in relation to forcing some schools to become academies. Do you thin - Essay Example This paper shall briefly discuss what neoliberalism is and how it impacts educational policies in the United Kingdom. It will then dwell on the issue of forcing some identified low performing schools to become academies. The Academies programme is part of the New Labour Coalition government’s efforts to improve the educational climate of schools. This paper shall evaluate if students’ educational attainment had indeed improve with the implementation of their educational policies. Educational Policies in the UK Ball (2008) summarizes the history of educational reform policies from the 1800’s. The early education policy was drafted to respond to the various needs of social classes, namely, to manage the new urban working class and to give the new middle class a chance to realize their aspirations. Next policy came in the mid 1990’s which found divisions within the public education systems culminating in the creation of comprehensive schools. Ball continues o n to the third prominent policy period from the last quarter of the 90’s wherein the New Right attempted to dismantle the welfare state and stress the importance of individual choice in education. Finally, the current policy reform was put into place under Tony Blair’s New Labour party from the late 90’s, advocating for a â€Å"competition state† taking practices from businesses into education. This current policy reform under the New Labour government is greatly influenced by neoliberal ideology. Ball (2008) criticizes the â€Å"policy overload† (p.2) as a manifestation of politicians creating an image for themselves that they are being proactive in their role as well as succumbing to pressures of globalization. Neoliberalism Neoliberalism was borne out of Adam Smith’s advocacy of classic liberalism as well as the concept of man, society and economics (Clarke, 2005). At its earliest stages, neoliberalism was viewed as an entirely new framew ork for managing the economy and drafting policies, which make up a capitalist society. Neoliberalism is associated with a set of political beliefs that strongly uphold the state’s purpose of safeguarding individuals specifically commercial, liberty and even their property rights (Nozick, 1974). It respects independent thinking of individuals enough to liberate them or minimize its hold on them and any transgression by the state beyond its purpose of safeguarding them is not acceptable (Harvey, 2005) Freely adopted market mechanisms are believed to be the right way of organizing exchanges of goods and services (Norberg, 2001) because it releases the creative potentials and entrepreneurial nature of people. In turn, it leads to more individual liberty and well-being and a more efficient allocation of resources (Rothbard, 2004). Munck (2005) argued that when government agencies intervene, it is almost always undesirable because it disturbs the natural rhythm of the marketplace, thus reducing its efficiency. Neoliberal Educational Policies Applied to education, neoliberals saw students as global capital and valued according to the skills they have gained to be contributory in the global marketplace. Hence, they should be invested upon and be trained to be competitive in order to bring out the best in them (DenBesten, et

Verification of MBTI Type Essay Example | Topics and Well Written Essays - 500 words

Verification of MBTI Type - Essay Example The ESFP personality profile was also chosen as the hypothesized one based on the description of the ESFP given by Myers and Briggs – â€Å"Outgoing, friendly, and accepting. Exuberant lovers of life, people, and material comforts. Enjoy working with others to make things happen. Bring common sense and a realistic approach to their work, and make work fun. Flexible and spontaneous, adapt readily to new people and environments. Learn best by trying a new skill with other people.† The test results that came back were ISFP – which matched the hypothesized profile on all but the first variable. The MBTI measures an individual's preferred modes of experiencing stimuli, and responding to them along four dichotomous variables. Each alphabet of the personality profile code stands for the dominant aspect of one variable. The first variable is Extraversion – Introversion; which attempts to understand the direction of focus of the individuals’ attentions. The report shows a preference towards introversion; signifying a tendency to look within and share significant events with a few close people rather than many acquaintances. The results also suggest that the individual would prefer to work alone, and prefer their own space. The hypothesised result on this variable was Extraversion – an assumption not supported by the test results.

Assignment 2 - Essay Example The insole and outsole are fitted with cork, allowing foot to form its own foot-bed for custom support. The shoes are durable and very fashionable. The advantage of buying the shoes was that it was worth the price, it was comfortable and available in a range of colours. The newspaper covered the topics that I liked reading. The disadvantage of the phone was that it was slightly expensive with poor camera quality. I was satisfied with the The Wall Street Journal newspaper because of how widely it featured its news from political scenes, business news and entertainment. However, I was dissatisfied with the purchase of the Samsung Galaxy S4 phone because the camera was not good for low-light shots, it had no Fm radio and the internal storage was limited because of the many applications. I intend to continue with the purchase of the newspaper and the shoes but for the phone, I will try another model like Nokia. My dad has one and its camera is great with low-light shots, it also has different designs, which give it exciting looks. According to Ramaswamy (2012), the first stage is needing identification. When I needed a phone, I choose the Samsung Galaxy phone after listening to my classmates. There were different phone models, but most of them recommended the Samsung phone because of its features. Thereafter, I started to process the information, which was further stimulated by watching television that evening, featuring an advert of the phone. Seth (2011) refers to this stage as information search and processing. I engaged in elaborate processing, by paying attention to the information available about the phone. I thought about the likely advantages and disadvantages of using it. When the information was processed and secured, I figured out other phone models, their features and where possible to get them. According to Ramaswamy (2012), this stage involves identification and evaluation of

William Shakespeare is the man who created beautiful poetry and he influenced people to create their own. In today’s modern day society, whether it’s widely read or not, poetry has the ability to be considerably moving and to truly touch people. Poetry is relevant and interesting in today’s society because it expresses a great array and depth of people’s feelings, it makes the reader connect with the poem, and it has a unique value. Also poetry is second-hand in music because in most hip-hop songs the words rhyme and create a rhyming couplet. Pursuing this further, poetry is a very powerful thing and it should be included in today’s up-to-date society. Unquestionably, all poems express feelings and emotions that the writer has dealt with throughout their life. Poetry expresses emotion in a form that delights the reader in one field and a feeling of sorrow in another. No other type of writing has the power or capability to arouse that much emotion other than poetry. Every living creature has feelings, but everything has its own way to express it. One way humans express their deepest feelings is through using their language to write and compose poetry. Reading poetry can help see through the eyes of the writer and see what they are experiencing. â€Å"This power rises from within, like the color of a flower which fades and changes as it is developed† (Shelley). This quote says that people have the ability to express themselves and that is very important in life. Poetry can make it easier to step into the shoes of someone else and learn about their personality. Without poetry, people would not be able to express their feelings and emotions and show people their real personality. Also poetry can help people by using it to release tension or stress that they need to get rid of. After a rough day at school, reading some poetry is a good way to get rid of the tension that is caused from problems such as taking a hard test or getting a lot of homework. Poetry helps soothe the mind and gives the mind a respite. Poetry uses the five senses to create a peaceful and pristine image using just words. One example that uses the five senses is, â€Å"All overgrown with azure moss and flowers/ So sweet, the sense faints picturing them† (Shelley). This quote uses the sense of sight because the image is so beautiful that your sense of sight faints. This style of writing can be very calming and comforting when read in a quite environment. Poetry is just like a car wash for the mind and soul; it freshens the soul and gives the mind a brand new start. Without poetry, there is one less way to get rid of stress and release tension. In addition to being used as a stress reliever, poetry is used to compose music. Just as in poetry, music also shares a basic element known as rhythm. In poetry there can be many different kinds of rhythm at the same time. Individual lines include unstressed and stressed syllables which is called a meter. There is also a rhythm between lines when metric patterns are repeated. In music, cadence is the beat of the music and the beats give the music its regular pattern. Poetry and music also display emotion and expression in their amazing works of art. Rap is made up of rhyme, rhythm, alliteration and many other poetic attributes. It is the most alike to poetry, however it is still music. Music without words is poetry, but not in the general state. Without poetry there would be no music because they are very similar and one can’t live without the other. Another reason why poetry is relevant is because it is much more entertaining to read compared to reading a book. Furthermore, poems are much more interesting to read instead of reading a long, boring book. Book plots and characters can be remembered for a limited period of time but poetry is one of the only forms of literary language that can be memorized. In the world of poetry, all of the rules that are applied to writing books are ignored and a piece of art is created that is completely unique. Poetry is such a short form of writing that the reader can think about the poem for hours without having their nose buried in a book. Poetry uses three ideas that are important to the text; mindful imagery, emotions, and language. Without these three things, poems would not have descriptions that use the five senses to create an image and people would lose interest in reading it. On the other hand, some people believe that poetry is irrelevant and this is why they are wrong. Some people might say that poetry is irrelevant and it is a waste of time. They might say that poetry is irrelevant because they believe it is boring to read and there is more people writing poetry than there is appreciating it. Poetry is relevant because it is much shorter and easier to read compared to reading a book. Poetry is very exciting to read because it expresses the feelings of the writer and puts the reader in the writer’s shoes. Poetry is enjoyable to read if you can understand and comprehend what is happening in the poem. Reading poetry is a surrogate form of reading and it is read by many people. Therefore, poetry is relevant and important in today’s society and should be respected more. In short, poetry is very relevant in today’s fast-paced, technological society for many reasons. Poetry is a way to let people express their emotions and show what their personality is like. Reading poetry is a salutary method to reduce stress and can relax the brain when it is overloaded with too many problems. Also poetry is a way to create a rhythm and there would be no music without poetry. Lastly poetry is much more entertaining to read compared to reading a long, boring book. Poetry is an aberration because it is much better than the standard. If poetry was never taught again in schools we would most importantly lose a vital language from our past. Poetry is only as relevant as the message of the poem, depending on how well it has been written. Works Cited Shelley, Percy Bysshe. Ode to the West Wind. Mcdougal Littell Literature.

Is friar Lawrence to blame Essay Example for Free

Is friar Lawrence to blame Essay Friar Lawrence is the local Roman Catholic priest who is also an apothecary. He is the confident of both Romeo and Juliet and plays an important role in the fate of both. He is more than aware of the familys feuding and seems to be well thought of by everybody. Romeo respects Friar Lawrence very much and sees him as a father figure. When Romeo feels suicidal when he has just been banished from Verona, the Friar tells him to straighten up. `This is dear mercy, and thou seest it not. ` When Romeo confesses that he wants to marry Juliet, Friar Lawrence teases Romeo about how fickle in love he is. `Is Rosaline, that thou didst love so dear, So soon forsaken? ` But in spite of this he still agrees to marry the young couple as he hopes it will end the familys feuding. `For this alliance may so happy prove, To turn your households rancour to pure love. ` He only agreed to it because he had their best interests at heart. I dont think he is to blame for marrying them as he did what he thought was right. And even if Friar Lawrence hadnt married them, whos to say that another Friar wouldnt have married them? Romeo and Juliet both feel as if they can turn to him when they are in trouble. We see this when Romeo has been banished, because he stabbed Tybalt and Juliet has been told that she must marry Paris. Romeo doesnt seem as if he is very close to either of his parents but Juliet usually has her nurse to turn to, but even the nurse, in the end the nurse rejects her too. `I think it best u married with the county. ` So in desperation each one goes to Friar Lawrence for help. Romeo is helped by being giving him a hide out in Mantua until Juliet can meet him. Juliet, being ordered to marry Paris, has gone to Friar Lawrence in desperation and has asked for help. First of all the Friar has to help Romeo escape. He allows Romeo to spend one night with Juliet, but before dawn he must leave. It is at this time that Juliet has been told to marry Paris. So she goes to the Friar. Friar Lawrence then devises a plan that will ensure Juliet and Romeos happiness. In some ways this shows us the Friars cunning, we are also shown that he is quite a smart man. We know that the friar is also an apothecary, so he gives Juliet a potion, which will make Juliet look as if she is dead. When she is taken to the family tomb, the friar will wait until she awakens, and by which time Romeo will hopefully already be there and take Juliet away. While devising this plan he still has the families interests at heart. He is only doing this in the hope that the two families, Montague and Capulet will reconcile. Although it could be argued, that he only helped them because he wanted to save himself. I personally dont think so. I think he would have known that he would have had to `cover his tracks` before he married the couple. He seems like a prudent man, one that will think things through; he would never have married them and helped them elope for selfish reasons. But the Friar did deceive both the Capulet and Montague parents. And although this was wrong, it was also, in my opinion justified. I think this because he didnt really have much choice. If he had wanted to succeed with his plan then they would have had to be kept in the dark, there was no other way round it. If they had been told, neither parent would have agreed to let their child associate with the child of the enemy. Priests do have the best interests of their parishes at heart and they do not lie and deceive people needlessly, but I think in this case it was allowed. Even though everything didnt turn out the way it should have, it achieved the one thing the Friar wanted: peace between the families. And although the price paid was very high, almost too high, the motivation was honourable he genuinely didnt act selfishly. I think everyone, in the play recognised this including the prince. `We still have known thee for a holy man. ` Friar Lawrence really was a decent man, even if his plans did go slightly wrong.

Transformer Oil Or Insulating Oil Engineering Essay

Transformer Oil Or Insulating Oil Engineering Essay CHAPTER 2 LITERATURE REVIEW 2.1 Introduction Transformer is one of the most useful appliances ever invented. Transformer can raise or lower the voltage or current in alternating current (AC) network, the circuit can be isolated from one another, and to increase or decrease the apparent value of a capacitor, inductor, or resistor. Furthermore, the transformer allows us to transmit electricity long distances and to circulate safely in factories and homes. (Electrical Machines, Drives, and Power Systems, 6th Edition). The cost of a transformer is high. The failure of one transformer resulted in a loss in terms of the price of one transformer or in terms of energy supply disruptions to consumers. Therefore, to monitor the transformer oil is one the right way and good for detecting the causes of damage to transformers. 2.2 Transformer Transformer is one of the most important electrical devices. Transformer is widely used in power systems and electronic devices. Transformer can also raise and lower voltage levels and the alternating current to suit application. Transformer can transfer power from one section to another on the same frequency but different voltage levels and currents. Transformer basically consists of two coils of a conductor which acts as an inductor electrically separate but magnetically attached. Transformer consists of two loops wrapped around the core base, core and coil which are a part of the transformer structures. Figure 2.1 shows the general structure of a transformer. When alternating current connected to the transformer primary windings, current will flow through the primary winding. Alternating current flows will create an alternating magnetic flux in the transformer core. The magnetic flux can flow to the secondary winding of the transformer through the transformer core. http://www.electricityforum.com/images/electrical-transformer-design.jpg Figure 2.1 General Structure of Transformer According to the Faraday law, the electromotive force or voltage is induced in the coil-winding transformer when the flux is changes in value. Because of the magnetic flux in the transformer core is an alternating flux whose value is constantly changing over time, the electromotive force or voltage is always induced in the coil-winding transformer. Electromotive force in the primary winding is known as the self-induced electromotive force is due to the flux generated by the coil itself. While the electromotive force induced in the secondary winding is known as mutual induction electromotive force due to the induced electromotive force is caused by magnetic flux generated from the primary winding. In an ideal transformer, the induced voltage in the secondary winding (Vs) is in proportion to the primary voltage (Vp), and is given by the ratio of the number of turns in the secondary (Ns) to the number of turns in the primary (Np) as follows: (Equation 2.1) By appropriate selection of the ratio of turns, a transformer thus allows an AC voltage to be stepped up by making Ns greater than Np, or stepped down by making Ns less than Np. There are many types of transformer are designed to meet the specific industrial applications. These include autotransformer, control, current, distribution, general-purpose, instrument, isolation, potential (voltage), power, step-up, and step-down. To avoid rapid damage of the insulating materials inside a transformer, sufficient cooling of the windings and the core must be provided. Indoor transformers below 200 kVA can be directly cooled by the natural flow of the surrounding air. The metallic housing is equipped with ventilating louvres so that the convection currents that can flow over the windings and around the core. Large transformers can be constructed in the same way, but the forced circulation of fresh air must be provided. Such as a dry-type transformers are used inside the building, away from the hostile atmosphere. Distribution transformers below 200 kVA are usually immersed in mineral oil and sealed in a steel tank. Oil carries the heat away to the tank, which it is lost by radiation and convection to the outside air. Insulating oil is much better than air, consequently, it is often used in high voltage transformers. As the power rating increased, external radiators are added to increase cooling surface of the tank contains oil. Oil circulates around the transformer windings and moving through the radiator, where heat released into the surrounding air. For still higher levels, cooling fans blow air over the radiators. For transformers in the megawatt range, cooling can be effected by the oil-water heat exchanger. Hot oil drawn from the transformer tank is pumped into the heat exchanger where it flowing through the pipes that are in contact with cold water. Such as heat exchanger are very effective, but also very expensive, because water itself must continuously cool and recirculated. Some large transformers are designed to have multiple ratings, depending on the cooling method used. Thus, the transformer may have triple ratings depending on whether it is cooled by: the natural circulation of air (AO) for 18000 kVA, or forced-air cooling with fans (FA) for 24000 kVA, or the forced circulation of oil accompanied by forced-air cooling (FOA) for 32000 kVA. These elaborate cooling systems are nevertheless economical because they enable a much greater output from the transformer of a given size and weight. The type of transformer cooling is designated by the following symbols: AA dry-type, self-cooled AFA dry-type, forced-air cooled OA oil-immersed, self-cooled OA/FA oil-immersed, self-cooled/forced-air cooled AO/FA/FOA oil-immersed, self-cooled/forced-air cooled/forced-air, forced-oil cooled The temperature rise by the resistance of oil-immersed transformers is either 55 °C or 65 °C. The temperature must be kept low to preserve the oil quality. By contrast, the temperature rise of dry-type transformer may be as high as 180 °C, depending on the type of insulation used. TEMCo offers the largest selection of High Voltage Transformers.GE Ventilated Dry-type Transformer Figure 2.2 Dry-Type Transformer Figure 2.3 Oil-Immersed Transformer 2.3 Transformer Oil Transformer oil or insulating oil is usually a highly-refined mineral oil that is stable at high temperatures and has excellent electrical insulating properties. It is used in oil-filled transformers. Transformer oil is likened to be the blood within the transformer body. It must be periodically tested to monitor condition of the transformer. Transformer oil serves three basic functions which are to insulate, to cool and maintain the transformer functions at all times. To keep these functions the industry has agreed on certain standards. The two leading transformer oil specifications in the world are IEC 60296 and ASTM D 3487. In these standards there are many specific requirement and limits based on physical and chemical properties. Many of these properties and their limitations stem from the chemistry of refined mineral oils in combination with application specific requirements of electrical insulation. In an age when alternative to mineral oil being developed, it is important both to know what is desirable and what is likely to achieved in technical terms. Whereas some brands of transformer oil could only meet the specifications, the others excel. In the end, transformer oil consumers should decide which properties are most important to their intended use. Technical specifications also have an impact on issues such as asset management, maintenance planning and investment budget. To aid decisions in these fields it is helpful to have a basic understanding of the science underlying specifications and limitations. In Malaysia, mostly used transformer oil is mineral crude oils (uninhibited mineral oils) which contains Paraffic, Naphteric or mixed. It is supplied by Hyrax Oil Sdn. Bhd. 2.3.1 Transformer Oil Properties The main function of transformer oil is insulating and cooling of the transformer. It should have the following properties: High dielectric strength and good dielectric properties resulting in minimum power loss. Low viscosity improves cooling. Freedom from inorganic acids, alkali, and corrosive sulphur. Resistant to emulsification. Rapid settling of arc products. Low pour point. High flash point resulting in low evaporation losses due to high thermal stability. High resistivity gives better insulation values between windings. Excellent interfacial tension for quick water separation. Proven resistance to electrical stresses. High electrical strength. Remarkably low sludge and acidity formation in both ageing and oxidation tests gives longer life to oil and equipment during storage and service. 2.3.2 Theory of Transformer Oil Parameters Water Content The standard for measuring water contain in oil is IEC 60814. (Marcel Dekker, 1990). The important function in transformer oil is to provide electrical insulation. When oil has higher moisture content, it can reduce the insulating properties of the oil, which may result in dielectric breakdown. This is the particular importance with fluctuating temperatures because, transformer will cools down if any dissolved water will become free and this oil become poor insulating power and fluid degradation. (Azliza binti Mohd Jelan,2009). Breakdown Voltage Dielectric strength is one of the important properties in insulation field. Breakdown voltage in insulating material is the maximum electric field strength that it can be withstand intrinsically without breaking down and without experiencing failure of its insulating properties, dielectric strength also means that a certain configuration and electrode dielectric material that produces minimal damage to the electric field. (Rohaina bt Jaafar, 2003). Breakdown strength in liquid according to various factors influenced in the experiment which is electrode material and surface state, geometry electrode, the presence of chemical pollutants, the presence of physical pollutants, oil molecular structure, temperature and pressure. There also various factors in the theory of voltage breakdown which is like electronic theory, suspended particle theory, cavitations theory and bubble theory were postulated. (Olive Oil from the Tree to the Table). Dielectric strength is also very dependent on the time and method of tension, purity materials, the type of tension as well as experimental and environmental parameters, until set of dielectric strength unique to the specific material is difficult, a range of values can be found and used for application purposes. (Noraniza binti Toriman, 2003). Figure 2.4 Heating / Cooling Curve of Oil (Ahmad Norhakimi bin Ibrihim @ Ibrahim, 2010) 2.3.3 Types of Transformer Oil Mineral Transformer Oil (Mineral Based Oil) A mineral oil or liquid petroleum is a liquid by-product of the distillation of petroleum to produce gasoline and other petroleum based products from crude oil. A mineral oil in this sense is a transparent, colourless oil composed mainly of alkenes (typically 15 to 40 carbons) and cyclic paraffin, related to petroleum jelly (also known as white petrolatum). It has a density of around 0.8 g/cm3. Mineral oil is a substance of relatively low value, and it is produced in very large quantities. Mineral oil is available in light and heavy grades, and can often be found in drug stores. There are three basic classes of refined mineral oils: Paraffinic oils, based on n-alkenes. Naphthenic oils, based on cycloalkanes. Aromatic oils, based on aromatic hydrocarbons (not to be confused with essential oils).

PDMS is the most widely used silicon-based organic polymer, and is particularly known for its unusual rheological (or flow) properties. PDMS is optically clear, and, in general, is considered to be inert, non-toxic and non-flammable. It is occasionally called dimethicone and is one of several types of silicone oil (polymerized siloxane). Its applications range from contact lenses and medical devices to elastomers; it is present, also, in shampoos (as dimethicone makes hair shiny and slippery), caulking, lubricating oils, and heat-resistant tiles.

Synthetic oil is used as a substitute for lubricant refined from petroleum when operating in extremes of temperature, because it generally provides superior mechanical and chemical properties than those found in traditional mineral oils.

If a proactive approach is adopted based on the condition of the transformer oil, the life of the transformer can be extended. Hence, transformer oil must be periodically tested to ensure its basic electrical properties. These tests can be divided into: Liquid Power Factor The IEC standard method for this test is IEC 247. This involves measuring the power loss through a thin film of liquid test. Water, contamination, and the decay products of oil oxidation tend to increase the power factor of oil. The new oil has very low power factor less than 0.1% at 25  ° C and 1.0% at 90  ° C. As the oil ages and moisture accumulates, or if the unit is contaminated, the liquid power factor tends to increase. Many owners make the mistake of having this transformer testing at only one temperature. While the test is more sensitive to 90  ° C, both the temperature should be used. The relationship between 25  ° and 90 ° values can assist in making the diagnosis as to whether the problem of moisture, oxidation, or contamination. (A Guide to Transformer Oil Analysis, by I.A.R. GRAY) Dielectric Breakdown Strength The dielectric breakdown voltage is a measure of the ability of the oil to withstand electric stress. Dry and clean oil showed the inherent high breakdown voltage. Free water and solid particles, especially the latter in combination with high levels of dissolved water, tend to migrate to areas of high electric stress and dramatically reduce the breakdown voltage. The measurement of breakdown voltage, therefore, serves primarily to indicate the presence of contaminants such as water or conducting particles. A low breakdown voltage can be indicating that one or more of these are present. However, a high breakdown voltage does not necessarily indicate the absence of all contaminants. This test was conducted in accordance with IEC 156. (A Guide to Transformer Oil Analysis, by I.A.R. GRAY) Moisture The purpose of dielectric tests are conducted is to ensure the monitoring moisture can be done directly. IEC 733 is a well established and can measure the moisture down to the low part of the million levels. While the acceptable values have been set by the voltage class for moisture, these are somewhat misleading. A truer picture of moisture in the transformer must be taken into account so that percentage saturation of the oil by moisture and percentage moisture by dry weight of the solid insulation can be calculated. A transformer at 20  ° C that containing 20 ppm moisture in oil is considerably wetter than a same unit, with a similar 20 ppm moisture, but it is operating at 40  ° C. The new transformer must be less than 0.5% moisture by dry weight. Anything more than 3.0% (or 30% saturation) is considered very wet. Many owners dehydrate transformer when the moisture level exceed 1.5 to 2.0% moisture by dry weight. (A Guide to Transformer Oil Analysis, by I.A.R. GRAY) Neutralization Number (Acidity) This value, measured by IEC standard method IEC 1125A reported as mg KOH / g sample, reports the relative amount of oil oxidation products, especially acids, alcohol and soap. As oil continues to oxidize, the acid increased gradually, generally over the years. Running the acid number regularly provides guidance as to how far oxidation of the oil has proceeded. The acceptable limit by the test is usually used as general guidelines to determine when the oil should be replaced or reclaimed. Acceptable values for acid number are 0.20 and lower. Unacceptable values are over 0.20.These are the values that are used by TNB. (A Guide to Transformer Oil Analysis, by I.A.R. GRAY) Interfacial Tension The test methods for interfacial tension (IFT), IEC 6295, measuring the strength in mN/m from the interface that will form between service aged oil and distilled water. Because the decay products of oil oxidation are oil and water soluble, their presence would tend to weaken the interface and reduce the interfacial tension value. Brand new oil is often 40-50 mN/m. A value that is acceptable for the in-service oil is greater than 25 mN/m or greater; unacceptable results are below 28 mN/m. (A Guide to Transformer Oil Analysis, by I.A.R. GRAY) Colour/Visual Field inspection of liquid insulation (IEC 296) includes examination for the presence of cloudy or sediment and the general appearance as well as a colour inspection. As oil ages, it will be darken gradually. Very dark oil or oil that changes drastically over a short period of time may indicate a problem. Any cloudiness or sediment indicates the presence of free water or particles that may be harmful to continued the equipment operation. Taken alone, without considering the past history or other test parameters, the colour is not very important to diagnose transformer problems. If the oil has an acrid or unusual odor, consideration should be given to carrying out further tests. (A Guide To Transformer Oil Analysis, by I.A.R. GRAY) Sludge/Sediment The IEC 296 test distinguishes between the sediment and sludge. Sediment is an insoluble substance present in the oil. Sediment may consist of insoluble oxidation or degradation products of solid or liquid materials, solid products such as carbon or metallic oxide and fibres or other foreign matter. Sludge is polymerized oxidation products of solid and liquid insulating material. Sludge is soluble in oil up to a certain limit. At sludge levels above this, the sludge comes out of the solution contributing an additional component to the sediment. The presence of sludge and sediment can change the electrical properties of the oil and prevent the exchange of heat, so encouraging damage to the insulating material. (A Guide to Transformer Oil Analysis, by I.A.R. GRAY) Inhibitor Content Inhibited oil deteriorates more slowly than uninhibited oil so long as active oxidation inhibitor is present. However, after the oxidation inhibitor is consumed, the oil can be oxidized at a higher level. Determination of oxidation inhibitor remaining in the in-service transformer oil is based on IEC 666. (A Guide to Transformer Oil Analysis, by I.A.R. GRAY) Dissolved Gas Analysis In contrast to the tests and the methods discussed to this point, the dissolved gas analysis (DGA) did not measure the gradual changes in the quality of oil. DGA has a very limited utility in determining the continued suitability of the transformer oil. The purpose and functions of the DGA is to provide an indication as to whether there may be an active or incipient transformer fault affecting the operation and continued health of the equipment. DGA is used to detect and measure nine of dissolved gases which are Hydrogen, Oxygen, Nitrogen, Methane, Carbon Monoxide, Carbon Dioxide, Ethan, Ethylene, and Acetylene. (A Guide To Transformer Oil Analysis, by I.A.R. GRAY) Dissolved Metals Analysis Analysis of dissolved metals (in particular, for the three metals: iron, copper, and aluminium) can be used in further identifying the location of transformer faults discovered by dissolved gas analysis. For example, the dissolved metal analysis indicating the presences of conductor metals may indicate a fault is occurring in the winding or at a connection while the presence of iron indicates involvement of the core steel. (A Guide To Transformer Oil Analysis, by I.A.R. GRAY) Furanic Compounds When paper breaks down, the cellulose chains are broken and glucose molecules (which serve as the building blocks of the cellulose) are chemically changed. Each of the glucose monomer molecules that are removed from the polymer chain becomes one of a series of related compounds called furans or furanic compounds. Because these furanic compounds are partially soluble in oil, they are present in both the oil and the paper. Measuring the concentration of the oil can tell us a little more about the paper. The standard method typically tests for five compounds that are normally only present in the oil as a result of the paper breaking down. Those five compounds, and their probable causes, are 5-hydroxymethyl-2-furaldehyde, 5H2F (typically formed by oxidation of paper), 2-furyl alcohol, 2FOL (typically formed in connection with a high moisture content), 2-furaldehyde, 2FAL (very common, formed by all overheating and aging conditions), 2-acetyl furan, 2ACF (very rare, may be related to elec trical stress), and 5-methyl-2furaldehyde, 5M2F (typically formed as a result of overheating). (A Guide To Transformer Oil Analysis, by I.A.R. GRAY) 2.3.4 Instrument / Device for Transformer Oil Testing Oil Test Set (Megger OTS 60 PB) The OTS 60PB is a 0 60 kV, battery powered portable dielectric strength oil test set. Its size and weight make it suitable for on-site assessment of insulating oil quality. The dielectric strength test it performs is an important deciding factor in knowing whether to retain or replace the oil. Breakdown voltage is measured, averaged and displayed under the control of built-in programmed sequences. Go/no-go testing is available. Figure 2.4 Oil Test Set (Megger OTS 60 PB) OTS 60PB follows the oil testing sequences described in many national and other specifications among which are: British BS 148, BS 5730a (automatic proof testing), BS 5874; International IEC 156, American ASTM D877 ASTM D1816, German VDE 0370, French NFC 27, Spanish UNE 21, Italian CEI 10-1, Russian GOCT 6581, South African SABS 555, Australian AS 1767 and Institute of Petroleum IP 295. Two types of withstand (proof) testing of an oil sample are available. The principle with these tests is to subject the oil sample to a specified voltage for a defined length of time (1 minute) to see if it will withstand that voltage. In one of the tests the voltage is removed after a minute, in the other test, the voltage continues to rise after the minute until breakdown or the maximum value is reached. Withstand (proof) tests can be set up to the users own requirements, and then repeatedly called up to quickly test oil under known fixed conditions. The OTS 60PB is used for determining the dielectric strength of liquid insulants such as insulating oils used in transformers, switchgear, cables and other electrical apparatus. It is portable and suitable for testing on site as well as in the laboratory. The test set is fully automatic. The operator has only to prepare the test vessel, load it with sample oil, place it in the test chamber, select the appropriate specification for the tests and then start the test sequence. The test set carries out automatically (and if necessary unattended) the sequence of tests as defined by the pre-selected national specification. Oil testing specifications, for which the set is pre-programmed, are as follows:- Figure 2.5 Oil testing specifications A 5 minute test sequence is also provided so that the operator may quickly obtain an idea of the breakdown value of an oil sample. Two types of semi automatic withstand (proof) testing of an oil sample are available. The principle with these tests is to subject the oil sample to a specified voltage for a defined length of time (1 minute) to see if it will withstand that voltage. In one of the tests the voltage is removed after a minute, in the other test the voltage continues to rise after passing for one minute until breakdown or the maximum value is reached. Withstand (proof) tests can be set up to the users own requirements, and then repeatedly called up to quickly test oil under known fixed conditions. The test results can be reviewed on the LCD or printed via the RS232 interface. An optional, battery operated printer is available to obtain a hard copy of the results. The safety features incorporated in the test sets design include two forced break switches used as described in B S 5304. These are interlocked with the oil vessel loading door. Volumetric titration system Metrohm Titrino SM 702 An automatic potentiometric titration system Titrino SM 702 with Exchange Unit 806 made by Metrohm measured the acidity of the oils. Here the Total Acid Number (TAN) was determined by a volumetric titration with potash to neutralize the carboxylic acids. The titration took place as follows: At first 10 g of the oil were dissolved in 40 ml of solvent toluene / ethanol in a ratio of 5 to 4. Potash (KOH, 0,1 mol/l) was added as titre with volume increments of 0.001 ml or 0.005 ml depending on the expected acidity. The system detects, when the acid-base-equivalence-point EP is reached by a voltage measurement in the solution. From the volume of potash at the EP equation below calculates the acidity as TAN: TAN total acid number EP1 equivalent point C31 blind value of the solvent toluene/ethanol CO1 0.1 mol/L, concentration of titre CO2 1 CO3 56106 g/mol, molar mass of titre CO0 weight of the oil sample Figure 2.6 Volumetric itration systems Metrohm Titrino SM 702 Kelman TRANSPORT X Portable DGA Unit And Moisture In Oil Dissolved Gas Analysis (DGA) is an established technique and is recognised as the most important test in monitoring power transformers. It is now being successfully extended to other oil filled equipment such as tap changers and circuit breakers. The TRANSPORT X unit has been designed to be very rugged and user friendly with an emphasis placed on field operation. The unit is used by over 200 companies and utilities and has sold in excess of 600 units worldwide.

Coke Strategy Essay -- Strategic Management Business

Coca Cola is the leading manufacturer, marketer and distributor of soft drinks in the world. With domestic market nearing saturation, the potential for growth lies in international markets. In recent years, economic, political and social changes have made the global environment more uncertain, forcing Coke to reevaluate its strategy, structure and culture to maintain a competitive advantage. The following is a dynamic analysis that tracks the evolution of Coke’s strategy from global standardization to a multi-domestic strategy that emphasizes national responsiveness. During Goizueta’s management term, Coke is already a large, mature company in the formalization stage of its life cycle and in the international stage of global development. The organization’s official goal is to dominate the global beverage market and maintain its market leadership position over Pepsi and other competitors. Its primary operative goals are productivity, efficiency and profit. Coke is a highly formalized, centralized organization with a clear hierarchy of authority and a mechanistic management process. Employees believe in the supremacy of the product, and the company’s rigid, heavy-handed culture helps maintain control and drive aggressive marketing and expansion plans. Given the steady consumer demand and low uncertainty created by the simple/stable environmental dimensions, the vertical structure is appropriate because it provides management with high degree of efficiency and control. Coke’s effectiveness is a result of the synergistic fit between its structural and contextual dimensions. Coke realizes economies of scale/scope and low-cost production from a globalization strategy that enables product design, manufacturing and marketing to be ... ...our product categories. With greater distances between regional units, Coke needs to establish more global coordination mechanisms such as transnational teams and functional managers to link resources, disseminate knowledge and bring products to market faster. To ensure that regional units don’t act too autonomously, headquarters needs to develop unified plans and procedures to ensure control and coordination. With more differentiation, Coke’s challenge is to stay competitive in new product categories without weakening the flagship product or diluting its brand image. Looking to the future, Coke should consider moving to a transnational model, which would transform the organization into a network of interdependent global operations that work together to achieve multi-dimensional goals by simultaneously achieving efficiency, national responsiveness and shared learning.

Because the parents of Chiyoda Little Leaguers will have to travel a greater distance, Maru believes there will be a lower response rate (8 percent) and a lower retention rate (65 percent), which she can make up for by purchasing slightly lowerquality jerseys, reducing the cost of sponsorship to just  ¥600 per player. However, the Chiyoda ward representatives demand that theirs be the only ward receiving such a sponsorship, which means MBC must choose between the two wards. The Chiyoda representatives argue that because their ward has twice the number of Little League customers, it is more attractive than the Minato ward. Should MBC pursue the Chiyoda ward sponsorship? Explain your reasoning.

China Returns to Africa Essay

The book â€Å"China Returns to Africa: A Superpower and a Continent Embrace† provides in-depth account of Chinese-African relations. The central claim of the book is that geopolitical relations between Africa and China has provoked international interests as China remains one of the most promising and powerful states in the world. The editors have assembled 24 essays by academics that possess exceptional knowledge with the purpose to shed light on the unexpected Chinese-African operations. The chapters address diverse subjects as, for example, social influence of Chinese Diaspora in Africa, the history of Tanzanian railway, the history of Chinese medicine, the progress of Beijing in buying oil and natural resources, the breadth of African continent, etc. The book presents a balanced impressive study of the most important developments in the modern worlds, as Chinese-African relations will affect economics and politics of all countries. In 2006 China celebrated a new strategic partnership. The interest of China in African continent has raised a number of debates as researches found it interesting to reveal what China expects from Africa. However, academic and development policy circles neglect country’s re-engagement with the African continent. In contrast to Europe and America, China treats Africa equally, not as inferior country. With the help of China Africa is viewed to be able to establish business deal with Western countries. In the late 1960s China made a decisive ideological thrust into the African continent and was humiliated for that by the rest of the world’s powerful countries and Africa itself. The painful experience of Mao’s men prevented further relations with Africa for about 40 years. The economic wreck was contributed to China’s disastrous experiments with socialism. A new invasion of Africa began in the past 15 years. New effort appeared to be more pragmatic and was driven mainly by a quest for new energy sources and new raw materials. Economic invasion was backed up by country’s huge wealth and, therefore, its implication was more likely to be far-reaching than the last Maoist adventure. Western powers were prompted to corresponding alarm as they were unaware what to expect from Chinese-African relations. The book notes that more than 800 Chinese companies have invested more than ? 5 billion in economic development of African countries and there is more to come. The editors admit in introduction that â€Å"China’s expanding relations with Africa are the most important dynamic in the foreign relations and politics of the continent since the end of the cold war†. (Alden et al. , 2008, ii) In particular, China offers African continent three things – money, long-term commitment and assurance of non-inference. Money offered accounted for larger sums that offered by western competitors and assurance of non-inference means that human rights won’t be troubled by Chinese lifestyle in contrast to European and American countries to impose their beliefs and policies within the continent. Thus, local dignitaries of African continent will remain original. Further, one of the chapters addresses the important of media in Chinese-African relations as media is the fourth power in the world. It is noted that Chinese media presents future of Chinese-African relations in different way from that of western reports and prophesies. Chinese partnership has expanded in Senegal, Mauritius and Cape Verde. Chinese traders are restoring the infrastructure in Angola. China buys cobalt from Congo and South Africa; feed from Ethiopia, Tanzania and Sudan; copper from South Africa and Zambia; chemicals from Nigeria; ferrous metals from Zimbabwe; and oil from everywhere. Angola has become China’s biggest supplier. The authors assess the costs and benefits of China’s re-engagement into African continent. On the one side, the prices are boosted by the increased competition for commodities. The West seems to be troubled about the Chinese imperialism because many of the trade practices have been commonplace among the European and American companies. Many countries simply tended to get out of Africa without investing in it. In contrast, China offers new scope of economic relations through equal treatment. Nevertheless, the poorest people in Africa would hardly benefit from Chinese-African relations as reliance on capital-intensive commodity industries is not effective way to fight poverty. The problem is that Chinese money goes into the pockets of Africa’s elites and into Swiss banks. The editors cite a spokesman of the Kenyan government who argues: â€Å"You never hear the Chinese saying that they will not finish a project because the government has not done enough to tackle corruption. If they are going to build a road, it will be built†. (Alden et al. , 2008, 23) Some authors are more skeptic about the future of the Chinese-African relations. They argue that with years the issue of ‘governance’ can’t be escaped as governance is the pre-condition of stable economic relationships and economic development. China is argued to suffer from lack of spiritual dimension in the countries practicing Christianity, Islam and other indigenous systems of beliefs. Overall, the book is very informative presenting multiple perspectives on development of Chinese-African relations. The authors offer far-reaching surveys of China’s return to the African continent. The new relations are assumed to hold for diplomacy, trade and further development. The authors are surely correct in their efforts to refuse taking high morale line about what China is willing to get from Africa. The positive is that China tends to treat Africa as equal partner, whereas Europe treated Africa as inferior state. Africa should be provided with more respect, the country should be provided with opportunity to decide what it wants and what it doesn’t want. With China, Africa may be able to strengthen its economic and political position in the world. Nevertheless, the negative is that China may tend to impose its own beliefs and governance similar to European countries. Development of Chinese-African relations depends fully on country’s abilities to cooperate. BIBLIOGRAPHY Alden, Chr. , Large, D. , & de Oliviera, R. , ed.

Megger’s Article Response Essay

Betty J. Meggers article, Environmental Limitation on the Development of Culture, examines how environmental habitats directly affect and influence culture. Meggers discusses the differing environmental types and its resulting effect on the people and their cultural development. Her theoretical framework is grounded on the idea that the relationship between culture and its environment is not only based in terms of subsistence (802), but largely to a culture’s experience with diffusion (822). Diffusion can best be defined as a process in which a cultural trait, idea, or behavior is spread from one society to another. While she does believe that the relative strength or weakness of an environment to provide a suitable means for food production affects the adaptation and advancement of a culture, she also believes that cultural diffusion plays a vital role as well. According to Meggers, the general belief is that environmental potentiality is the sole conditioner of cultural development (801). The span of environmental habitats into classified into 4 environmental types, ranging from Type 1 environments, which have the least agricultural potential, to Type 4 environments, which have unlimited agricultural potential. Meggers does generally seem to agree that the environmental type can set limitations on the level of development a culture is able to obtain (816). Because Type 1 environments have the least agricultural potential, tribes must subsist mainly by hunting, fishing, and gathering. Cultures that live in Type 1 environments are relatively small in population size and tend to lead more of a nomadic lifestyle, a necessary part of life because they must continually follow their food source. As a result, their existence is noticeably simplistic because their primary focus is on satisfying only their very basic needs such as shelter and food. This type of environment results in a culture where social organization and technology is very limited in scope. The nomadic lifestyle necessitates that tribes remain relatively small, therefore making the single family the basic social unit. Additionally, technology remains limited to only the most essential tools and utensils due to the limited resources available. According to Meggers, Type 1 and Type 2 environments seem to prohibit cultural advancement because of the limitations imposed on a culture by the environment and the general lack of a suitable source of diffusion. Conversely, Type 4 environments have unlimited agricultural potential because they possess all the ideal conditions necessary for sustaining agriculture. Meggers calls Type 4 environments the â€Å"cradles of civilization† (804) because of their ability to develop and implement the technology necessary to sustain an agriculturally based lifestyle. Type 4 environments are typified by their complex social organization and cultural advancements. Meggers states that Type 4 civilizations are elaborate due to their intensive production of food and the necessary means of distribution. However, Meggers also believes that success of Type 3 and Type 4 environments to advance culturally is also heavily influenced by diffusion across cultures, or a cultures relative exposure and adoption of differing cultural norms, beliefs, and behaviors.

Parental Involvement And Parental Participation Education Essay

In the literature, the impressions of parental engagement and parental engagement are frequently non clearly operationalized ( Feuerstein, 2000 ) . The description of ‘parental engagement ‘ has been expanded from engagement of parents at school to include engagement of parents in the instruction of their kids at place ( Smit et Al, 2007 ) . Desforges ( 2003 ) , for illustration, distinguishes two signifiers of parental involvement/ engagement, viz. ‘spontaneous ‘ versus ‘planned. ‘ Whereas the first is bottom-up, the 2nd is more top down and typically concerns intercessions or programmes aimed to work out the job of insufficient or no parental engagement. Epstein ( 1995 ) defines place, school and community partnerships as representing a relationship between â€Å" three major contexts in which pupils live and turn † ( p. 702 ) and in which shared involvements in and duties for kids are recognized. In add-on, Funkhouser and Gonzales ( 1997 ) province that successful partnerships involve the sustained common coaction, support and engagement of school staffs and households at place and at school, in activities and attempts that have a positive consequence on the academic success of kids in school. Because place, school and community represent the major overlapping domains of influence in kids ‘s instruction and development, research workers and practicians call for their coaction as spouses who â€Å" work together to make better plans and chances for pupils † ( Epstein, 1995, p. 701 ) . Socio-cultural research workers define â€Å" community † as a â€Å" community of pattern † – that is, a group of people engaged in an activity driven by common or closely decussate ends and involvements ( Wenger, 1998 ; Wenger, McDermott & A ; Snyder, 2002 ) . In chase of these ends and involvements, they employ common patterns, work with the same tools or resources and utilize specific discourse. Communities constitute societal contexts and significances for larning as people participate in societal patterns. Knowledge is integrated in the making, societal dealingss and expertness of these communities. Furthermore, the procedures of larning and rank in a community of pattern are inseparable. Because acquisition is intertwined with community rank, it is what lets people belong to and set their position in the group. As participants change, their acquisition and their individuality – relationship to and within the group – besides alteration. Theref ore, communities constitute the most powerful learning environments for kids, making potency for their development as kids engage in societal patterns with others. This attack to larning suggests that instructors need to understand their pupils ‘ communities of pattern and admit the acquisition pupils do in such communities ( Saxe, 2002 ; Sfard, 2002 ) . Pulling on communities ‘ financess of cognition can capitalise on cultural diverseness and get the better of any mismatch between pupils ‘ place environments and the civilization of school. McIntyre, Rosebery and Gonzalez ( 2001 ) argue that minority and hapless kids can win in school if schoolroom patterns give them the same advantage that in-between category kids have – direction that puts cognition of their communities and experiences at the bosom of their acquisition. In the position of these research workers, larning mathematics is more than structured individualised knowledge ; it is besides dependent on the societal and cultural state of affairs and values of the scholar. International research points to big differences in the mode in which and extent to which parents are involved in the instruction of their kids. The differences have been found to be associated with, among other things, the societal and cultural background and thereby social-ethnic composing of the school population. The grade and signifier of engagement, harmonizing to Desforges ( 2003 ) , are strongly influenced by societal beginning, educational background of the female parent, material want, the psycho-social wellness of the female parent, turning up in a single-parent household and-but to a lesser extent-ethnicity. The sentiments of the parents sing their function and their degree of trust in their ability to carry through this function have besides been found to be of critical importance ( Symeou, 2001 ; Phtiaka, 2001 ) . Kohl, Lengua and McMahon ( 2000 ) conclude on the footing of a comparing of ‘black ‘ and ‘white ‘ parents in deprived vicinities in th e USA that there are no differences for a figure of facets of parental engagement but decidedly differences for a figure of hazard factors, such as parental instruction and single-parent household. The writers emphasize that the quality of the engagement is more of import than the measure. Driessen, Smit and Sleegers ( 2005 ) conclude that the extent to which the kid is unfastened to parental engagement is the strongest forecaster of parental engagement at place while parental engagement at school depends chiefly on the extent to which instructors invite such engagement. Sheldon ( 2002 ) points to the importance of the size of the societal webs of parents as an of import forecaster of parental engagement. The treatment in the earlier subdivisions of the survey shows the paradigm displacement that has occurred with respects to seeing instruction as non merely the primary duty of either the parents or the school. What emerges, hence, is acknowledgment of the mutuality among parents, schools, and the community to foster a common goal-that is, the proper instruction and conveying up of kids, a undertaking that is clearly womb-to-tomb in nature ( Ndahayo and Gaikwad, 2004 ) . In fact, a good figure of research point to the fact that kids do better when there is an integrating of attempts between their parents and the school ( for illustration, see Pleyvak and Heaston, 2001 and Ndahayo and Gaikwad, 2004, among others ) . Harmonizing to the Scots Inspectorate of Education ( 2006 ) , the close working relationships between parents and schools help to develop kids ‘s larning attitudes, therefore doing them more capable of accomplishing their full potency. At the same clip, parental engagement ensures that instructors have a clearer and better apprehension of the kids ‘s household fortunes and personal accomplishments and traits. Parents are similarly benefited by this agreement because now they are in a better place to understanding what their kids larn, how good they are acquiring along in category and with friends and, most significantly, how they can lend positively to back up such larning in their ain place. Clear communicating channels between parents and instructors allow them address issues and concerns rapidly and efficaciously, so as to minimise their negative impact on the kids. Parents play an of import function in assisting their kid foster a positive attitude towards athleticss, as they are the 1s who can act upon future athletics activity picks ( Kanters, 2008 ) . Parents have besides come to see their kids ‘s engagement in competitory athleticss as a cardinal constituent in their overall socialisation. It is non merely the school that portions the load of duty with parents in the proper instruction of kids. For illustration, the UK authorities has besides already recognized the fact that doing kids larn the importance of regular physical activity in relation to good wellness has to be tackled even at the policy doing degree ( Hemming, 2007 ) . This recognizes that society has to step in and do compulsory certain facets of the proper instruction of kids to ease their development, because parents and schools can merely travel so far without holding a unvarying and effectual model to work with in implementing their programs and plans for wellness act ivities ( Hemming, 2007 ) . The fact that bulk of the school-based wellness enterprises launched in the UK in the past few old ages represents an of import paradigm displacement: the accent on developing a immature population that is physically active and healthy is no longer the exclusive duty of parents and persons, but of the school system every bit good. Epstein ( 1995 ) said that the theoretical account of overlapping domains of shared influence among the three major contexts where pupils learn and grow-the household, school and community-can be drawn together or pushed apart, depending on the collaborative model that is established among them. This theoretical account locates the pupil at the centre of acquisition, and so all attempts are geared towards assisting them advancement in their instruction and socialisation. Padavick ( 2009 ) noted that one of the most of import factors for the successful academic public presentation of kids is the engagement of parents in their acquisition. His survey presented an thorough analysis of relevant literature that surrounds the thought of parental engagement in the raising procedure of kids, along with the assorted theoretical constructs that have attempted to specify merely what parental engagement agencies in such a context. He wrote that parental engagement emerged as a construct in the learning procedure of the kid in 1890s, when the demand to specify the relationship between parents and schools became evident. Parent/teacher associations were the first establishments that linked the parent to the school. Later on, this led to the engagement non merely of educational governments in the attention and upbringing of the kid, but besides of the province. The US federal authorities began to pay more attending to the different plans that can lend to the positi ve development of the kids and the household, by tapping into the resources and activities of the school. The consequence of such engagement, nevertheless, turned out to be unfortunate, because the parents easy delegated the opportunity-or undertaking, depending on how one perceives the matter-to usher their kids ‘s acquisition to the school governments and to the authorities. Because of the lesser accent that was given to their existent aid in determining the educational accomplishment of the kids, parents took on a more inactive engagement in the surveies of the latter ( Padavick, 2009 ; Wright, Tim, 2009 ) . This mellow attitude of the parents can be traced to changing perceptual experiences of the parents and the instructors with respects to the extent of parental engagement of the former in their kids ‘s instruction. Clearly, meaningful relationships can merely be built if both parties understand the importance of their common engagement in the upbringing and instruction of the kid. Parents tend to believe that one time they have provided financially for the instruction of their kids, their function in the educational procedure has already been satisfied ( Flakes, 2007 ) , but this is far from the truth. Parents really have the lasting duty non merely to care for the kid but besides to educate him or her continuously, such that they could non wholly depute the undertaking of instruction to the instructors in school. Students benefit from this agreement because they can still demo successful academic accomplishment despite other factors that can function to draw down the same, if and when parents are able to demo active support throughout their early educational old ages. The impression of parental engagement in the instruction of kids is important because it will demo the extent to which parents are responsible for the latter ‘s instruction. It can function as the threshold boundary for indicating out where the duty of school decision makers, instructors and society starts. It is through their active engagement that parents show their echt involvement non merely in the development of their kid, but besides in their academic accomplishment and schooling ( Padavick, 2009 ) . Parental behaviour is of import in instilling the first survey wonts of the kid because it is the parents who foremost set up the demand to hold appropriate survey and drama times, every bit good as giving encouragement and motive for them to make their prep and other school-related activities. Therefore, they set up non merely the outlooks that their kids must endeavor for, but besides familiar modus operandis that would assist the latter focal point on their surveies and better academic public presentation subsequently on ( Cotton and Wikelund, 1989 as cited in Padavick, 2009 ) . Motivation is an of import facet of acquisition because it is what pushes the scholar to really absorb the lessons that he or she learns in school and to utilize it along with other old cognition and accomplishments. Motivation allows for the different edifice blocks of larning to go one incorporate whole, therefore determining the kid ‘s experiences and positions. Any sort of larning requires a good sum of motivation-both from the portion of the pupil to whom the information will be given, and from the portion of the instructor who is expected to supply the necessary input to jump-start the acquisition procedure. Therefore, it is besides of import to look at how motive affects the quality and velocity of the acquisition procedure, and to see how to increase such motive particularly on the portion of the pupil. For illustration, LiuolienA- and MetiA «nienA- ( 2006 ) have noted that motive in 2nd linguistic communication ( L2 ) larning research has received much attending in the past decennary, particularly motivational theories in drama inside the L2 schoolroom. Research workers agree that motive plays a critical function in the scholar ‘s accomplishment, if merely because the impulse to larn is coming from an internal, non an external, beginning. So powerful is motive that it can really be harnessed to overrule other larning factors such as linguistic communication aptitude, to impact the pupil ‘s public presentation in both negative and positive ways. But parents are non the end-all and be-all of the instruction of their kids. Even as school boards and decision makers try to prosecute the parents of their pupils in meaningful working relationships to better the behaviour and academic public presentation of the latter, it is still of import to observe that the motive to larn is non supplied merely by the parents. Such relationships would take to a more incorporate attack in raising the saloon of outlooks and accomplishments that a kid could achieve. Therefore, it appears from the research that it is the instructors who foremost initiate the constitution of a working relationship between the parents, school, and society at big ( Padvick, 2009 ) . There is accent on the fact that parents can travel out of inactive support for their kids ‘s instruction to taking a more proactive function in the latter ‘s development, to the point that they become â€Å" life-long coachs † who are willing to maintain unfastened lines of communicating with the instructors of their kids so that increased academic public presentation may be achieved ( Padavick, 2009 ) . Home-schooling parents may be the lone exclusion to the regulation in the sense that they do non hold to organize with their kid ‘s instructors to supervise and better the former ‘s academic public presentation. But the kid will non remain homeschooled everlastingly. For this intent, it is of import that home-schooling parents recognize that they may hold to portion the load and the privilege of holding joint influence over their kid ‘s instruction with his or her instructors in the hereafter. Majority of the literature points to the fact that there is a deficiency of sufficient parental engagement in determining the educational public presentation of the kid ( Padavick, 2009. Therefore, it is of import to understand the outlooks and parts that each stakeholder-parent, instructor or community-can spring to the positive development of kids. This is of import because merely when ends and involvements of all the parties concerned are established can earnest attempts to an integrating of schemes be made. Of class, every instructor would desire non merely a motivated pupil, but besides a pupil who has the benefit of a good family-school-community partnership to back up his successful academic accomplishment. The job, nevertheless, is that there is a deficiency of co-ordinated attempts among these three spouses in procuring the proper development of the kid. In this respect, the instructors can really utilize some aid in making effectual schemes that can construct meaningful partnerships between them and the parents and communities of the pupils and convert them to be more actively involved in the kids ‘s acquisition. Parental attitudes in larning impact on how their kids view instruction every bit good, and they can therefore be used as an of import tool for manipulating and increasing the kids ‘s involvements in their ain surveies Hill, Nnenia ( 2009 ) . However, possibly because of their occupations or their household duties, parents have been giving lesser attending to their kids ‘s acquisition procedure. Therefore, it is the instructors who must make ways and agencies to make out to the parents and convert them to take on a more active portion in the educational enterprises of the kids. For illustration, instructors have to efficaciously convert the parents non to go excessively intimidated with the school environment and the instructors who take over their kids ‘s instruction Hill, Nnenia ( 2009 ) . Parents do non ever experience welcome or needed in the learning procedure of their kids, so this may be one ground why they would instead withdraw to the out of boundss, so to talk. This serves as the individual biggest barrier that stops the parents and instructors from acquiring across to one another to construct a meaningful relationship that will profit the kids the most and guarantee their uninterrupted instruction and development. Snowflakes ( 2007 ) farther noted other grounds why parents do non collaborate with the instructors in guaranting the high educational accomplishment of their kids, particularly among parents of kids who belong to minority groups. There is a deficiency of general trust in the educational establishments, uncomfortableness in talking to the instructors, and a inclination to compare the examining inquiries of the instructors to disrespect. In this respect, it is of import for instructors to assist parents experience at place in the working relationship and to promote their engagement in a positive mode. This can merely be done if both parties know how much each one can lend to the development of the kid, in order to complement the other in the best manner possible. But the working relationship is uncomplete without the active engagement of the 3rd of import factor-the community ( Epstein 2001 ) . The overlapping domains of influence that Epstein ( 2001 ) had identified are situated in such a manner that the kid is found at the centre. The community is every bit of import as either of the other two factors because it can really function to beef up impressions that relate on the extent of the function of the household and the school in the upbringing of the kid. For illustration, Corner and Haynes ( 1997 ) noted that the deficiency of working relationship between parents and instructors in some inner-city vicinities in the United States have been intensified because of the unreal differentiations that society has created between the two. Society says that the school is responsible merely for the academic acquisition of the kid, while the household has sole power over the kid ‘s emotional and moral development. This categorised system of acquisition has someway prevented parents and instructors from making out to one another in order to make meaningful partnerships directed at bettering their kids ‘s holistic instruction. The truth of the affair is that kids do non halt larning wherever they may be ( Corner and Haynes 1997 ) . They do conveying their cognition from either place or school into the other. Therefore, it is of import to make a seamless larning environment between the place and the school in order to assist incorporate the kid ‘s cognition and acquisition experiences. This is where the community comes into the image. By supplying policies and plans that can beef up the parent-teacher relationship, the community can lend to the positive development of the kid. Epstein ( 2001 ) wrote that portion of the end of the working relationship is to make a â€Å" family-like school † or â€Å" school-like policy † , constructs that conveying together the best that each acquisition sphere has to offer. Abromitis ( 2009 ) likewise noted that with the community supervising the coordination of attempts between parents and instructors, effectual sharing of resources is possible. For illustration, schools can supply parents and their kids easy entree to community resources and services that they may necessitate in order to hike the latter ‘s academic public presentation. Smit, Driessen, Sluiter and Sleegers ( 2007 ) have investigated the types of parents and school schemes to make en effectual partnership. The consequences of this survey showed that parents in white schools support the instructors on activities ; these parents are represented as protagonists. On the other manus, parents that are non in the non-minority group and evidently with high societal position ever have a say in school affairs. These parents act as politicians. In contrast, schools with a batch of pupils that is disadvantaged, parents are given small or no attending in a say for school affairs. There is a constriction in white schools for parents that have no clip to back up the activities. These parents are career parents. On the other manus, there is a constriction in black schools as the parents here do non comprehend themselves as qualified in take parting in assorted school activities. These parents are labeled as absentee parents. It is farther shown in the research that strategies that are parallel with the different types of parents can be identified in school squads in order to recognize effectual partnership dealingss. Meyer, Armstrong-Coben and Batista ( 2005 ) described a theoretical account of community-academic partnership in New York City. The partnership included paediatric occupants and Alianza Dominicana, Inc. , a community based societal service organisation. The end of the partnership was to advance child wellness and development in the community. Harmonizing to the 2000 nose count, 72 % of the community served described themselves as Dominican. The community was located in a rural country with economically disadvantaged working category occupants. Meyer et Al. ( 2005 ) reflectively described four rules that lead to the success of this culturally diverse partnership. First, a trusting relationship was established among university module, paediatric occupants and community occupants. The relationship took old ages to develop because of misconceptions between the paediatric occupants and the community. The community perceived university module as the â€Å" Ivory Tower † and the paed iatric occupants as â€Å" chesty and omniscient † . The paediatric occupants perceived the community as destitute and deficient assets. Initially, the paediatric occupants did non see the assets within the community. Therefore, the message was to abandon prejudices in order to hold a positive working relationship. This was achieved through preparation Sessionss led by community leaders and module members. Community leaders bit by bit gained leading functions within the medical residence plan. Next, the constitution of specific defined ends was determined. The formation of the board of managers, dwelling of representatives from the community, module and occupants, was the 3rd rule and the last rule taking to the success of the partnership was unfastened communicating utilizing a common linguistic communication. The creative activity of a common linguistic communication was developed through â€Å" Narrative Lunches † , an activity for occupants and community members to speak about cultural differences in an unfastened duologue ( Meyer et al. 2005 ) . Buttery and Anderson ( 1999 ) published a synthesis and literature sing the kineticss between the parents, community and school. In drumhead, they emphasized that interaction between and among places and school are really important for constructing a acquisition environment. The United States has stood long before the publicity of instruction in kids every bit good as the publicity of parental partnership with the community for the overall growing of kids. This will further heighten the effectivity of the schools. Smit and Driessen ( 2005 ) published a survey sing the importance of instruction as a requirement in the engagement of parents every bit good as the instructors in the intercultural jobs at school and in the society. However, in most instances, there underlies a deficiency in communicating. It has been suggested that instructors and parents should be more cognizant of the fact that they need each other in pass oning better sing the pedagogical jobs particularly at place and school. Besides, they need to pass on in incorporating their part to the kids ‘s upbringing and instruction. Boaduo, Milondzo and Adjei ( 2009 ) conducted a survey sing parent-community engagement in school administration and its consequence on instructor ‘s effectivity and betterment on the public presentation of the scholars. The survey was conducted in primary and secondary schools in Botswana. The careworn decision from this said survey is that in schools wherein parents and community engagement is really seeable, instructors are effectual and contributes to the pupils ‘ positive behaviour and their public presentations ‘ improved. Coleman and Hutchens ( 1995 ) conducted a predicted survey of administrative and teacher variables sing their communicating in early childhood instruction. Four 100s eighty three preschool instructor samples were studied. Consequences of multiple arrested development analysis showed that the features of early childhood scene that is associated with administrative determination contributes chiefly in explicating the discrepancy of how frequently parents and instructors communicate. Kilpatrick, Johns and Mulford ( 2003 ) conducted a survey sing the development of community partnerships in larning in the rural communities. It was concluded in this survey that the attack to school-community relationship is really important to the long-run opportunities of success. A tactical attack affecting a series of tactics or speedy holes, or a strategic attack concentrating merely on peculiar countries of failing and schemes to turn to these countries, are non as likely to be every bit successful as on-going capacity constructing originating from a sense of shared school-community vision for the hereafter. At the same clip, it must be recognized that edifice of school-community partnerships occurs over clip, and leading procedures must admit and construct on this. It is aimed of holding a school and community that have a sense of bureau ; that is, an ability to move purposefully in chase of ends, to self-regulate, and to larn and alter as and when they decide it is in their corporate involvements to make so. In a similar survey by Goos, Lowrie and Jolly ( 2007 ) , wherein Australia is the topic, they have explored the originating research on educational partnership between households, schools and communities. The partnership ‘s impacts in larning diverseness in kids ‘s numeracy and acquisition were studied. It was concluded in this survey that in the field of place, school and community partnerships there is no consistent understanding about the significance of the footings â€Å" partnerships † , â€Å" parent engagement † and â€Å" community engagement † . Many different sorts of activities fall within this field. In add-on, the stakeholders in these connexions between place, school and community may keep conflicting perceptual experiences about numeracy, and about their functions and the functions of other stakeholders. In analyzing effectual partnerships in numeracy instruction, the importance of relationships, common trust, and regard developed over an drawn-out period of clip was a subject that emerged from our instance survey analysis. This indispensable good will can non be created wholly by support or targeted plans, and plans such as the Mobile Pre-school Pilot Program and Distance Education in rural Australia owe their success to a long history of cooperation and joint endeavor centered on the public assistance and instruction of kids, their households and communities. It was besides notable that some of the most effectual partnerships we identified for our instance surveies were non initiated as numeracy plans but took a more holistic attack ( cf Hexter, 1990 ) . The research indicates that constructing strong home-school-community partnerships around kids ‘s acquisition in general can put the basis for numeracy-specific acquisition. In culturally diverse communities we would propose that partnership edifice is of paramount importance, and should continue – or at least accompany – the debut of educat ional plans that seek to originate kids into numeracy patterns that are valued but different from those of their place civilization. Plenty of grounds was found that parents truly care about their kids ‘s instruction, it was every bit clear that non all parents want to be actively involved in all facets of schooling and many see their function as chiefly a supportive 1. Possibly the most productive manner forward is to concentrate on what each participant – parent, instructor, community member – can convey to the partnership that will do best usage of their diverse expertness, backgrounds, and involvements in back uping the kid ‘s numeracy acquisition. Dhingra, Manhas and Sethi ( 2007 ) examined the parents ‘ engagement of parents in school related activities. Further, it listed the assorted agencies of communicating being used by parents to get information sing the kids ‘s public presentation and suggestion on bettering the relationship between schools and parents. It was found that parental engagement in schools was limited. Very few of them were members of regulating commission or acted as resource individuals. Whenever there was incidence of engagement male parents exceeded in Numberss. Parents were largely concerned about the academic public presentation of their wards. Majority of female parents visited schools on a regular footing to cognize about their kid ‘s public presentation. The issues of treatment were chiefly behavior of the kid and general school public presentation. However, parents used varied beginnings to garner information about kid related issues and the most normally used medium was school d airy ( 71 % ) followed by parent instructor meeting ( 50 % ) , school magazine etc. Another national survey explored passage patterns ( Early, Pianta, Taylor, & A ; Cox, 2001 ) and examined the hypothesis that school-centered passage patterns had three features: 1 ) provided outreach to households, preschools, and communities ; 2 ) looked back in clip to do connexions before kid entered school ; and 3 ) provided activities of appropriate strength. Using informations from the National Center for Early Development and Learning ( NCEDL ) Transition Practices Survey ( stratified, random sample of over 10,000 kindergarten instructors ) , research workers described passage patterns and identified passage barriers. Between-group comparings were conducted from over 3,500 questionnaires. Main findings showed that instructors with preparation in passage activities made attempts to vary activities. Delaies in obtaining category lists created barriers to optimal passage pattern. Besides, schools need to make ready environments instead than keeping high outlooks of single kids à ¢â‚¬Ëœs school preparedness. Jewett et Al. ( 1998 ) engaged in a narrative survey of four simple instructors to understand what is involved in efficaciously back uping school preparedness ( i.e. , passage ) of kids with particular demands. Research workers used informations from instructors ‘ brooding diary Hagiographas from April to December 1996. Consequences were categorized into five passage undertakings. A subject of stressfulness emerged based on many challenges for instructors. Research workers suggested schools must admit instructors ‘ overpowering duty and aid in relieving stressors by supplying extra support and resources. Another Head Start survey explored instructors and kids as co-creators of behaviours characterized as at hazard or promise as kids transitioned to kindergarten. Researchers conducted an ethnographic survey in 1993 that included observations over a 6-month period at a local Head Start/Transition Demonstration site. Skinner, Bryant, Coffman, and Campbell ( 1998 ) followed 21 pupils in the mark group through kindergarten. Field notes were analyzed which revealed grounds that even in the first hebdomads of school, instructors and preschoolers showed marks of co-constructing patterns that moved kids onto a way of school failure. Issues of race and civilization became portion of the discourse and co-construction. Teachers held unrealistic outlooks to â€Å" repair † the at hazard kid. Traditional learning environments did non back up kids ‘s ongoing development whereas those who spent more clip and energy pulling out kids ‘s single strengths co-created concepts of promis e. Ethnographers acknowledged that kids ‘s academic promise was a joint duty of schools, places, communities, and larger society. The offering of chances for parents to take part in the instruction of their kids has been found to exercise a positive influence on the cognitive development and accomplishment of students ( Boethel, 2004 ; Driessen & A ; Smit, 2007 ; Epstein et Al, 2002 ) . However, a few surveies show no effects of such chances ( Mattingly, Prinslin, McKenzie, Rodriguez & A ; Kayzar, 2002 ) . Parental engagement is besides frequently considered one of the most of import constituents or features of effectual schools ( Driessen, Smit & A ; Sleegers, 2005 ) . In add-on to the positive effects of parental engagement on the school accomplishment of kids, positive effects on the societal operation of students have besides been found in assorted surveies. This involves facets of the behaviour of students, their motive, societal competency, the dealingss between instructors and students, and the dealingss among the students themselves ( Boethel, 2003 ; Henderson & A ; Mapp, 2002 ; Jordan, Orozco & A ; Ave rett, 2001 ) . Meyer, Armstrong-Coben and Batista ( 2005 ) described a theoretical account of community-academic partnership in New York City. The partnership included paediatric occupants and Alianza Dominicana, Inc. , a community based societal service organisation. The end of the partnership was to advance child wellness and development in the community. Harmonizing to the 2000 nose count, 72 % of the community served described themselves as Dominican. The community was located in a rural country with economically disadvantaged working category occupants. Meyer et Al. ( 2005 ) reflectively described four rules that lead to the success of this culturally diverse partnership. First, a trusting relationship was established among university module, paediatric occupants and community occupants. The relationship took old ages to develop because of misconceptions between the paediatric occupants and the community. The community perceived university module as the â€Å" Ivory Tower † and the paed iatric occupants as â€Å" chesty and omniscient † . The paediatric occupants perceived the community as destitute and deficient assets. Initially, the paediatric occupants did non see the assets within the community. Therefore, the message was to abandon prejudices in order to hold a positive working relationship. This was achieved through preparation Sessionss led by community leaders and module members. Community leaders bit by bit gained leading functions within the medical residence plan. Next, the constitution of specific defined ends was determined. The formation of the board of managers, dwelling of representatives from the community, module and occupants, was the 3rd rule and the last rule taking to the success of the partnership was unfastened communicating utilizing a common linguistic communication. The creative activity of a common linguistic communication was developed through â€Å" Narrative Lunches † , an activity for occupants and community members to speak about cultural differences in an unfastened duologue ( Meyer et al. 2005 ) . Some of the literature beginnings advised that the determination about the precise nature of parent engagement must take into history cultural, cultural and category differences every bit good as fluctuations related to the age and gender of scholars ( Fullan, 2001 ) . Furthermore, Shaeffer ( 1994 ) is of the sentiment that in finding what conditions parent-community engagement is most good we have to understand the different signifiers of parent-community engagement and their effects for the school, the scholar and other forces in the whole school system. The ground provided by Shaeffer and others is that certain signifiers of engagement produce positive consequences while others may be uneconomical or wholly antagonistic productive ( Anderson, 1991 ; Shaeffer, 1994 ) . Leadership processes in order to convey approximately and back up sustainable alteration within educational scenes ( e.g. Mulford, 2003 ; Lambert, 1998 ; Sergiovanni, 1994 ) . Leithwood ( 1994 ) and Silins & A ; Mulford ( 2002 ) argue that transformational leading facilitates effectual school reform. Transformational leading patterns of school leaders include the development of a widely shared school vision and collaborative civilization, furthering the committedness and capacity of staff, administering duty for leading, and back uping coaction with appropriate resourcing. These impressions of leading are supported in the community development literature ( e.g. Henton, Melville & A ; Walesh, 1997 ; Langone & A ; Rohs, 1995 ; Chrislip & A ; Larson, 1994 ) . Other elements or edifice blocks for effectual schoola?’community partnerships are summarized by Schorr ( 1997 ) , who found that successful plans: are non mandated by policy but respond to community demands ; rely on the co mmunity ‘s ain resources and strengths ; pull extensively on outside resources for support, proficient expertness and to act upon policy ; and are based on strong relationships based on common trust and regard which are sustained by institutional support. Schorr ( 1997 ) besides noted that successful schoola?’community partnerships have a long-run orientation and go on to germinate over clip. Other factors identified in the literature as act uponing the school-community partnership include size of the school and community and propinquity of the school to the community, continuity of resources, and the importance of promotion and bipartisan communicating ( Carlsmith & A ; Railsback, 2001 ; CRLRA, 2001 ; Miller, 1995 ; Combs & A ; Bailey, 1992 ) .
