The Definition of Hydrophobic With Examples

To be hydrophobic means to fear water. In chemistry, it refers to the property of a substance to repel water. It isnt that the substance is repelled by water so much as it has a lack of attraction to it. A hydrophobic substance exhibits hydrophobicity and may be termed hydrophobic. Hydrophobic molecules tend to be nonpolar molecules that group together to form micelles rather than be exposed to water. Hydrophobic molecules typically dissolve in nonpolar solvents (e.g., organic solvents). There are also superhydrophobic materials, which have contact angles with water greater than 150 degrees. Surfaces of these materials resist wetting. The shape of water droplets on superhydrophobic surfaces is called the Lotus effect, in reference to the appearance of water on a lotus leaf. Superhydrophobicity is considered a result of interfacial tension and not a chemical property of matter. Examples of Hydrophobic Substances Oils, fats, alkanes, and most other organic compounds are hydrophobic. If you mix oil or fat with water, the mixture will separate. If you shake a mixture of oil and water, the oil globules will eventually stick together to present a minimum surface area to the water. How Hydrophobicity Works Hydrophobic molecules are nonpolar. When they are exposed to water, their nonpolar nature disrupts hydrogen bonds between water molecules, forming a clathrate-like structure on their surface. The structure is more ordered than free water molecules. The change in entropy (disorder) causes nonpolar molecules to clump together to decrease their exposure to water and thus decrease the entropy of the system. Hydrophobic vs. Lipophilic While the terms hydrophobic and lipophilic are often used interchangeably, the two words dont mean the same thing. A lipophilic substance is fat-loving. Most hydrophobic substances are also lipophilic, but exceptions include fluorocarbons and silicones.

A. Context of Culture According to Malinowski (1923), context can be distinguished into three types: context of utterance, context of situation and context of culture. The context of utterance here is similar to the linguistic context that later scholars argue, which refers to the words and sentences in which a particular words or sentences embeds. Malinowski further argues that the concept of context has to be broadened and that the situation in which words are uttered can never be passed as irrelevant to the linguistic expression. Therefore, he put forth the term â€Å"context of situation to refer to the wider idea of context or the general conditions under which a language is spoken. † And the context of culture, Malinowski observes that it is the reality of the culture, the life and the customs of a person in which language is essentially rooted. To sum up, Malinowski find that to understand the meaning of what is said, we should not only consider the particular context of utterances, but also take into account the culture characteristic of the society.

Sapir developed their powerful view called â€Å"Sapir-Whorf hypothesis† which the culture provides the context within words are interpreted.

Zakes Mda redressing the past Essay Example For Students

Zakes Mda: redressing the past Essay South African playwright Zakes Mda has the outward calm and practiced smile of one who has answered the same obvious questions many times before. In a cool, dark office on the Yale University campus, he sits rather uncomfortably across the table from me, his speech reserved, his hands extended palms downward on the tabletop in a strangely formal gesture. Only occasionally does he raise his fingertips or his voice to punctuate his carefully chosen words. And yet Mdas passion is obvious when the topic turns to American impressions of South African drama. South African theatre is notthe voice and the fingertips come momentarily to lifea homogeneous monolith. What Americans see as representative of South African drama, Mda explains, are plays written purely for export and in a manner which is acceptable to overseas audiences but which fails to depict the rich and varied cultural and political context of contemporary South Africa. What is seen outside of South Africa, touring European and American venues, represents only one or two categories of what makes South African theatre.

Although his work is virtually unknown in this country (with the notable exception of The Road, which won the American Theater Associations Christina Crawford Award in 1984), Mdas reputation as a political playwright, poet, painter and educator is well established in Europe and in Africa, especially in his native country, where his political writings for the stage have seen frequent production since the late 1970s at the Peoples Space Theatre in Capetown, the Market Theatre in Johannesburg and the Grahamstown Festival. His three volumes of published dramatic works include We Shall Sing for the Fatherland (1978), The Hill (1979)both winners of major writing awards and the highly acclaimed And the Girls in Their Sunday Dresses. Born in South Africas impoverished rural Cape Province, Mda was forced as a teenager to follow his parents into political exile in nearby Lesotho, a tiny independent sovereignty surrounded on all sides by South Africa and heavily dependent on the larger nation for economic survival. Lesotho is widely known as a pocket of political resistance in southern Africas landscape, a place of exile for many black refugees. It is also at the heart of South Africas sprawling rural outlands: desolate areas of inhuman living conditions, abusive mining practices and slave-like farm labor which constitute a kind of South African Siberia far from the urban and industrial hubs of Capetown, Johannesburg and their adjacent black townships. It is primarily these urban areas and the experience of the township dwellers (particularly young, unattached males) which serve as the focus of South African drama and literature seen in the U.S. By comparison, Mdas plays evoke a South Africa of rural hardship and exile little known to Americans. Plays such as The Road, The Hill and Dark Voices Ring (1979) document the miles of open, unpaved road and the hostile terrain traversed by mine workers and migrant laborers in search of employment; they are peopled with the unwilling itinerant, the relocated and dispossessed, the political-refugee. Mdas latest play, The Dying Screams of the Moon, written while he was in residence at Yale, dramatizes a controversy regularly making the news in post-apartheid South Africa and, not incidentally, serves as the playwrights response to what he sees as the limited political and racial perspective of another contemporary public event: Athol Fugards most recent work, Playland. Like that drama, Mdas The Dying Screams of the Moon depicts an interracial encounter between two strangers in present-day South Africa. I have always enjoyed Athol Fugards work, says Mda. But at the same time I have vehemently disagreed with him in almost everything he has written. My South Africa is different from Athol Fugards South Africa. Thats the crux of the matter. .u6ff8599ba4eb54252e42eda60a29e69b , .u6ff8599ba4eb54252e42eda60a29e69b .postImageUrl , .u6ff8599ba4eb54252e42eda60a29e69b .centered-text-area { min-height: 80px; position: relative; } .u6ff8599ba4eb54252e42eda60a29e69b , .u6ff8599ba4eb54252e42eda60a29e69b:hover , .u6ff8599ba4eb54252e42eda60a29e69b:visited , .u6ff8599ba4eb54252e42eda60a29e69b:active { border:0!important; } .u6ff8599ba4eb54252e42eda60a29e69b .clearfix:after { content: ""; display: table; clear: both; } .u6ff8599ba4eb54252e42eda60a29e69b { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u6ff8599ba4eb54252e42eda60a29e69b:active , .u6ff8599ba4eb54252e42eda60a29e69b:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u6ff8599ba4eb54252e42eda60a29e69b .centered-text-area { width: 100%; position: relative ; } .u6ff8599ba4eb54252e42eda60a29e69b .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u6ff8599ba4eb54252e42eda60a29e69b .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u6ff8599ba4eb54252e42eda60a29e69b .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u6ff8599ba4eb54252e42eda60a29e69b:hover .ctaButton { background-color: #34495E!important; } .u6ff8599ba4eb54252e42eda60a29e69b .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u6ff8599ba4eb54252e42eda60a29e69b .u6ff8599ba4eb54252e42eda60a29e69b-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u6ff8599ba4eb54252e42eda60a29e69b:after { content: ""; display: block; clear: both; } READ: Court clashes over free speech Essay No happy endings   Mda feels that in Playland as well as earlier plays, Fugard has depicted black South Africans as meek, humble, pitiable people who just accept all with stoic endurance. Mda refuses to corroborate this fatalistic typing of his people; he also refuses what he calls the happily ever after ending of Playland, a piece which one South African critic labeled theatre of reconciliation. Reconciliation, nods Mda. Thats a very wishful situation, but the play does not address the crucial issues in South Africa now. The ownership of landand the difference between current government attempts at reconciliation and true reparation for injustices of the pastis the subject of The Dying Screams of the Moon. In Mdas words, The past must be addressed. And not only must it be addressed, it must be redressed as well. Under the Group Areas Act of 1912, the South African government forcibly removed black communities from their ancestral lands, declaring those lands white only areas for purposes of, among other things, economic development. Such development frequently meant that white commercial farmers were given exclusive right to purchase the confiscated property at extremely reasonable prices. Since the repeal of the Act in 1989, thousands of displaced and homeless blacks have redoubled their ongoing attempts to reclaim what was forcibly taken from them. A taste for sexual equality   People have wanted to return to their ancestral lands from day one, insists Mda. They didnt just move away like Boesman and Lena and start wandering around. They refused to move. But the government prevailed because it was all too powerful. Now, explains Mda, the problem is even more complex because the land legally belongs to white farmers, some of whom have been living on it for generations. In The Dying Screams of the Moon, a middle-aged black woman identified only as Lady has returned to the Valley of the Moon to reclaim the land from which she was forcibly removed as a child. The valley is now known as Victory Farms, a title given it by the white landowner whose family purchased the land decades earlier and who has turned it into a highly profitable commercial farm. The farmers interests are represented in the play by his daughter, Missy, a young woman who, like the white veteran Gideon le Roux in Playland, is a former soldier of the South African Defense Force, the military body responsible for forcibly putting down black resistance and for fighting the bloody and long-standing war of occupation with neighboring Namibia. Lady, it turns out, is also a veteran of South Africas violent race struggles, but from the opposite side: She is a former freedom fighter who has planned and executed guerrilla attacks on South African targets while living in forced exile. Bitter stalemate   What these former warriors share, they eventually discover, is a taste for the relative sexual equality they experienced as women given ranking positions of authority in the military. However, that taste has been tainted by the professional jealousy of male comrades and of lovers. Both women have lost their male companions by refusing to resume subservient female roles when returning to civilian life. This shared experience of personal potential cut short by sexual jealousy and oppression becomes a point of bonding between the interracial pair. Like the two men in Fugards Playland, these women enact a communal bearing of witness and a mutual absolution of sins in the course of the play. And yet, Mda ends Dying Screams on a note of bitter stalemate between these two newfound friends over their mutually exclusive claims to the land. In the words of Lady, Healing and redemption will only come when the pain of the past, which is in fact our present pain, has been addressed. .ub982d9578f150ea203410dcac644c999 , .ub982d9578f150ea203410dcac644c999 .postImageUrl , .ub982d9578f150ea203410dcac644c999 .centered-text-area { min-height: 80px; position: relative; } .ub982d9578f150ea203410dcac644c999 , .ub982d9578f150ea203410dcac644c999:hover , .ub982d9578f150ea203410dcac644c999:visited , .ub982d9578f150ea203410dcac644c999:active { border:0!important; } .ub982d9578f150ea203410dcac644c999 .clearfix:after { content: ""; display: table; clear: both; } .ub982d9578f150ea203410dcac644c999 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ub982d9578f150ea203410dcac644c999:active , .ub982d9578f150ea203410dcac644c999:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ub982d9578f150ea203410dcac644c999 .centered-text-area { width: 100%; position: relative ; } .ub982d9578f150ea203410dcac644c999 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ub982d9578f150ea203410dcac644c999 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ub982d9578f150ea203410dcac644c999 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ub982d9578f150ea203410dcac644c999:hover .ctaButton { background-color: #34495E!important; } .ub982d9578f150ea203410dcac644c999 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ub982d9578f150ea203410dcac644c999 .ub982d9578f150ea203410dcac644c999-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ub982d9578f150ea203410dcac644c999:after { content: ""; display: block; clear: both; } READ: Violet - A Musical by Jeanine Tesori and Brian Crawley EssayWe would like to have that wishful ending that Playland has, Mda laments, but the perspective of the black people is that as long as justice has not been served, there will never be any true reconciliation.

Académie Française, the Moderator of the French Language

Acadà ©mie Franà §aise, the Moderator of the French Language The Acadà ©mie Franà §aise, often shortened and simply called  lAcadà ©mie, is an organization which moderates the French language. The primary role of the Acadà ©mie Franà §aise is to regulate the French language by determining standards of acceptable grammar and vocabulary, as well as adapting to linguistic change by adding new words and updating the meanings of existing ones. Due to the status of English in the world, the Acadà ©mies task tends to be focused on lessening the influx of English terms into French by choosing or inventing French equivalents. The Primary Function of the Acadà ©mie Officially, the Article 24 outlines that The primary function of the Acadà ©mie will be to work, with all possible care and diligence, to give our language definite rules and to make it pure, eloquent, and capable of dealing with art and science. Maintaining a Common Linguistic Heritage The Acadà ©mie fulfills this mission by publishing an official dictionary and by working with French terminological committees and other specialized organizations. Strangely, the dictionary is not sold to the general public, so the Acadà ©mies work must be incorporated into society by the creation of laws and regulations by the above-mentioned organizations. Perhaps the most notorious example of this occurred when the Acadà ©mie chose the official translation of email. Obviously, this is all done with the expectation that French speakers will take these new regulations into consideration, and in this way, a common linguistic heritage can theoretically be maintained among French speakers around the world. In reality, this is not always the case. Created by Cardinal Richelieu in 1635 The Acadà ©mie Franà §aise was created by Cardinal Richelieu under Louis XIII in 1635, and the first Dictionnaire de lAcadà ©mie ranà §aise was published in 1694 with 18,000 terms. The most recent complete edition, the 8th, was finished in 1935 and contains 35,000 words. The next edition is currently underway. Volumes I and II were published in 1992 and 2000, respectively, and between them cover A to Mappemonde. When complete, the 9th edition of the Acadà ©mies dictionary will include approximately 60,000 words. Its important to note that this is not a definitive dictionary, as it generally excludes archaic, offensive, slang, specialized and regional vocabulary. Linguistic and Literary Patronage The secondary mission of the Acadà ©mie Franà §aise is that of linguistic and literary patronage. This was not part of the original purpose of lAcadà ©mie, but thanks to grants and bequests, the Acadà ©mie now offers about 70 literary prizes per year. It also awards scholarships and subsidies to literary and scientific societies, charities, large families, widows, underprivileged persons and those who have distinguished themselves by courageous acts. Peer-Elected Members Essentially a linguistic jury, the Acadà ©mie franà §aise is a group of 40 peer-elected members, commonly known as Les Immortels  or  Les Quarante. Being chosen as an Immortel is considered a supreme honor and, except in extreme cases, is a life-long commitment.Since the creation of lAcadà ©mie Franà §aise, there have been more than 700 Immortels who were  chosen for their creativity, talent, intelligence and, of course, particular linguistic adeptness. This range of authors, poets, theater people, philosophers, doctors, scientists, ethnologists, art critics, soldiers, statesmen and churchmen assembles at lAcadà ©mie into a unique group of people who make decisions on how French words should be used by analyzing how they actually are, creating new terms, and determining the beneficiaries of the various awards, scholarships, and subsidies.In October 2011, the Acadà ©mie launched an interactive feature called Dire, Ne pas dire on their website in the hopes of bringing pure French to the cyber masses.

Overview of Theories Essay Example | Topics and Well Written Essays - 750 words

Overview of Theories - Essay Example By understanding the numerous theories, it thus becomes possible to understand the behavior of children. The discussion below is an over view of three vita theories that explain the cognitive development of children. The three include Piaget’s Cognitive-Developmental Theory, Vygotsky’s Sociocultural Theory and Bronfenbrenner’s Ecological Systems Theory. Each of the three just as hinted above offers a varied view to the development of children. The discussion is therefore an over view of the three with the view of portraying the fundamental features of the theories and the ideas that each theory foster. By analyzing such, the discussion thus portrays the essence of the environment among other factors in the development of the children. The theory strives to explain the nature of knowledge. It explains the process of acquiring knowledge, its construction and subsequent use of knowledge in humans. The theory therefore portrays the fundamental factor that influence the definition of knowledge and the factors that influence the relevance of such. The theory asserts that children begin by understanding the world around them before experiencing the discrepancies that exist between their knowledge and the actual features of the environment as they interact with the people. The theory underscores the importance of language. It explains that language is a contingent on the process of cognitive development. The theory therefore explains the factors that influence the cognitive development of individual by explaining the development of children. The people that a child interacts with first influence the nature of their development. Such people as the family members influence the child’s understanding of the society. Furthermore, the theory provides language as a means of assessing the cognitive development of a child. Using language
