Definition and Examples of Clustering in Composition

In composition, a discovery strategy in which the writer groups ideas in a nonlinear fashion, using lines and circles to indicate relationships. Clustering Clustering (sometimes also known as branching or mapping) is a structured technique based on the same associative principles as brainstorming and listing. Clustering is distinct, however, because it involves a slightly more developed heuristic (Buzan Buzan, 1993; Glenn et al., 2003; Sharples, 1999; Soven, 1999). Clustering procedures vary considerably, although the fundamental objective is to equip students with tools for arranging words, phrases, concepts, memories, and propositions triggered by a single stimulus (i.e., a piece of information, a topic, a provocative question, a metaphor, a visual image). As with other [invention] techniques..., clustering should first be modeled and practiced in class so students can eventually incorporate the tool into their own repertoire of invention and planning strategies.(Dana Ferris and John Hedgcock, Teaching ESL Composition: Purpose, Process, and Practice, 2nd ed. Lawrence Erlbaum, 2005) Guidelines for Teaching the Clustering Process What instructions should you give to begin this prewriting process? I have found the following both appropriate and effective:(Gabriele Lusser Rico, Clustering: A Prewriting Process, in Practical Ideas for Teaching Writing As a Process, ed. by Carol B. Olson. Diane, 1996)Tell students that they are going to use a tool that will enable them to write more easily and more powerfully, a tool similar to brainstorming.Encircle a word on the board--for example, energy--and ask students, What do you think of when you see that word? Encourage all responses. Cluster these responses, radiating outward. When they have finished giving their responses, say, See how many ideas there are floating around in your heads? Now, if you cluster all by yourself, you will have a set of connections as unique to your own mind as a thumbprint is to your thumb.Now ask students to cluster a second word for themselves. Before they begin, tell them that the clustering process should take no more than one or two min utes and that the paragraph they will write should take about eight minutes. Ask them to keep clustering until the Aha! shift, signaling that their mind is holding something they can shape into a whole. In writing, the only constraint is that they come full circle: i.e., that they do not leave the writing unfinished. Some excellent words are afraid or try or help.After they finish writing, ask students to give a title to what they have written that is suggestive of the whole. Mind-Mapping Mind-mapping is a colorful and creative method of generating, organizing, and remembering ideas. To mind-map, write your topic in the center of a blank page within a visual representation of your topic, such as a giant musical note, a sailboat, or scuba gear. If no central image comes to mind, use a box, heart, circle, or other shape. Then use various colors of ink to color-code related ideas. From the central figure draw radiating lines like the rays of the sun or branches and roots of a tree. Then, as you think of parts of the subject you wish to discuss, jot down pictures, key words, or phrases on or near these lines. Also add examples and subparts using branching lines and more images and words. If you do not already have a central focus for your essay, watch for a key phrase or image as you complete your exploration.(Diana Hacker and Betty Renshaw, Writing With a Voice, 2nd ed. Scott, Foresman, 1989) Also Known As: branching, mapping

Population Growth Density Dependent Factors Abstract...

Population Growth: Density dependent factors Abstract Sets of experiments were used to assess the growth rate of the Lemna minor, a duckweed population. The growth of Lemna minor was observed and followed by counting and recording the number of thalli on a weekly basis. These experiments were constructed lab models which varied the size of the starting thalli population, and varied the nutrient concentration the thali were placed in. In the first experimental model two plastic cups were prepared with pond water, then two healthy lemna minor plants were placed in the first cup while fifteen healthy lemna minor plants were placed in the second cup. The second experimental model consisted of four nutrient concentrations, a control model of no nutrients, a low nutrient model, a medium nutrient model and a high nutrient model. At high density populations, we observed a nonlinear decreasing growth rate with increasing lemna minor density. At very low densities, as expected, we observed an inverse density dependence. Duckweed reproduces by budding, causing a larger density to reproduce a greater amount of biomass. This would indicate that Duckweed likes overcrowding, and this may be a possible clue to the limiting factor in the growth of Duckweed. Introduction Lemna minor, commonly known as duckweed, is efficient and fast growing, making it an ideal experimental organism. It is known as a small aquatic monocotyledon which can be found floating in ponds, lakes or streams (Harper,Show MoreRelatedThe Effects of Population Density on the Reproduction and Survival of Daphnia Magna2308 Words   |  10 PagesAbstract The population dynamics of Daphnia magna are observed under three different conditions; low, medium, and high density.

Mamie Clark Free Essays

Running head: MAMIE CLARK 1 Famous Person in Psychology: Mamie Phipps Clark MAMIE CLARK 2 Famous Person in Psychology: Mamie Phipps Clark Mamie Phipps Clark was born in Hot Spring, Arkansas on April 18, 1917 to Dr. Harold and Katie Phipps. Due to her father having a practice in town the family had achieved middle class status and was allowed into many establishments that were normally whites only, which during that time in Arkansas was rarely heard of. We will write a custom essay sample on Mamie Clark or any similar topic only for you Order Now Even though few higher educational opportunities were open to black students, after graduating from Langston High School in 1934, Mamie was offered several scholarships and chose to accept one from Howard University. (Cherry,2013) Mamie chose to study at Howard University because it was located in the nation’s capital and because of the many accomplished black members of its faculty whom she viewed as role models. She began her studies at Howard as a math major, minoring in physics. There she met her future husband, Kenneth B. Clark, who was studying for his master’s in psychology. After not getting much encouragement from her professor’s in mathematics, Kenneth encouraged Mamie to change her major to psychology for employment possibilities and the chance to explore her interest in children. (Cherry, 2013) When completing her master’s degree in 1939, she worked and studied children in an all-black preschool. During that time she met with pyschologists, Ruth and Gene Harley who were studying self-identification in young children and encouraged Mamie to do the same with the children in the preschool. This resulted in her completed thesis â€Å"The Development of Consciousness of Self in Negro Pre-School Children†. (Cherry,2013) MAMIE CLARK 3 Mamie transferred to Columbia University to finish her doctorate degree, where she graduated in 1943 as the second African American to earn a degree (first eing her husband, Kenneth Clark). Then Drs. Mamie and Kenneth Clark used their research with children to show that black children became aware of their racial identity by the age of 3 and by segregating them from white children the children saw their race as negative. This led the Clark’s to present their findings during desegregation trials for the NAACP’s case in Brown v. Board of Education, which overturned racial segregation in public schools in 1954. (Mamie Clark, 2013) After several years working in public and private social services being unsatisfied with what she saw, Mamie founded the Northside Center for Child Development, the first center to provide therapy for children in Harlem. At a time when public schools were illegally enrolling many black children into programs for the mentally handicapped, the center conducted its own intelligence tests, fought the schools, and empowered the local population. Realizing that therapy alone could not address the affects of racism on the community, Northside also assisted families with their housing and financial difficulties. Mamie Clark worked for Northside until retirement in 1980 and died three years later of cancer. (Mamie Clark, 2013) Using the Sociocultural aspect of psychology, it is easily seen that Mamie Clark was influenced by social and cultural she experienced in her life. Growing up in Arkansas during the times where racism were very apparent and segregation was dominant, she was fortunate enough to have been born into a middle class family. Mamie was able to see both sides of the segregation by being allowed into white establishments. This had a significant impact on her way of thinking, she wanted to both races to be seen equally and this eventually led to her involvement in the desegregation of public schools.

Characteristics of Developing Countries free essay sample

The Structure of Industry †¢ It is widely assumed that all developing countries depend upon the production and exporting of primary products. †¢ While this may be true of many developing countries, many are reliant on basic manufactured products for exports. eg: Bangladesh) †¢ Others such as Cape Verde and Maldives are actually mainly exporters of services in the form of tourism. 6. Per Capita Income Levels †¢ Although it is often assumed that all developing countries have very low levels of income per capita, we should be aware that there are marked differences between per capita income from developing country to developing country. †¢ Venezuela has a high GDP per capita, but it is still very much a developing country. 7. Political Structures Developing countries have very different political structures from each other. Democracies Such as Brazil, Indonesia and Mexico Monarchies Such as Brunei and Tobago Military Rule Such as Myanmar and Pakistan Single Party Rule Such as China, Cuba and Syria Transitional Political Systems Where a country is in transition often caused by conflict and civil war and cannot be classified (e.

Somalia) Within each structure, there are of course many substructures. Example Democracies may be presidential systems, semi-presidential systems, parliamentary republics or constitutional monarchies. o The main point is that with developing countries being so diverse in their systems or government, it is very difficult to establish one-size-fits all solutions to developmental problems. To conclude, we can say that while there are some common characteristics that are held by developing countries to some degree, there are also several significant differences. o One must be very cautious in making generalizations that imply that all developing countries are the same Characteristics of Developing Countries free essay sample Characteristics of Developing Countries BY Hafeez260 The theme of this essay is: the importance of a study of other semi-developed countries as they struggle for economic growth, the elimination of mass poverty and, at the political level, for democratisation and the reduction of reliance on coercion. New countries are finding their voices in all sorts of ways and are managing to interest an international audience. South Africa is not least among them; contemporary international consciousness of the travail of our particular path towards modernity testifies at least to a considerable national talent for dramatic ommunication and (for those who care to look more deeply) a far from extinct tradition of moral conscientiousness. One aspect of this flowering is a rapidly growing crop of social scientific studies of semi-developed countries of which this university is fortunate to have a substantial collection, contained mainly in the library of Jan Smuts House. From this literature, one can extract five themes of particular interest. We will write a custom essay sample on Characteristics of Developing Countries or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The first is the problem of uneven development and effective national unification, especially in deeply divided societies. Capitalist development has mpinged on semi-developed countries from outside rather than transforming slowly from within, incorporating different groups in different ways. Particular problems arise when differential incorporation coincides in substantial measure with boundaries between ethnic groups. If Donald Horowitzs remarkable study of ethnic groups in conflict is right, more energy goes into attempting to maximise differences in the welfare of in groups and out groups than into maximising their Joint welfare, with adverse consequences for the possibilities of building the national political and economic institutions required for development. Gordon Tullock has argued that this is an additional reason for preferring market-based rather than state-led economic growth in deeply divided societies. In itself it is, but the secondary effects of different paths on distribution have to be taken into account. In so far as they lead to worsening differentials between groups, the possibility of heightened conflict is created. The only long-term hope is to make ethnic boundaries less salient; the happiest outcome would seem to be when ethnicity becomes decorative in a high income economic environment. This is likely to be the work of decades, perhaps of enturies; even so, appalling retrogressions always seem to remain possible. The consequence of deep divisions is that there is likely to exist an unusually large number of prisoners dilemma situations. The prisoners dilemma arises when partners in crime are apprehended and held separately. The prisoners will be Jointly better off if they do not inform on each other, but each prisoner will be better off if he informs on the other, while the other does not inform on him. Attempts at individual maximisation may lead to both prisoners informing on each other which leads to the orst Joint outcome. The dilemma arises because of the absence of the o pportunity for co-operation. ) Under such conditions, negotiation skills are at a premium. There are also advantages in the acceptance of a deontological liberal philosophy which (in the shorthand of political philosophers) places the right over the good. This involves seeking to regulate social relations by Just procedures while leaving individuals as free as possible to pursue their own, diverse conceptions of the good life. Such an attention should be paid simultaneously to the reduction of poverty. The analytical Marxist, Adam Przeworski has analysed analogous problems which arise in the case of severe class conflict. In his view, social democratic compromises are held together by virtue of the propensity of capitalists to reinvest part of their profits with the effect of increasing worker incomes in the future. Class compromise is made possible by two simultaneous expectations: workers expect that their incomes will rise over time, while capitalists expect to be able to devote some of their profits to consumption. In conditions of severe class conflict, these expectations about the future become ncertain, time horizons shorten, workers become militant, capitalists disinvest and political instability results. Three forms of resolution are available: stabilising external intervention, negotiation or renegotiation of a social contract or the strengthening of the position of one or other class by a shift towards conservatism or revolution. Przeworskis sternest warnings are to Marxists who assume that revolution and the introduction of socialism is the inevitable outcome of a crisis. The second theme in the literature on semi-developed countries has to do with their position within the world economy. Three related sub-themes can be identified. Firstly, there has been a debate about the forms and limits of the diffusion of industrialisation. Dependency theory now somewhat out of fashion, since its predictions of severe limitations on industrialisation in developing countries have been falsified asserted that relationships between developing and developed countries are such as to keep the latter in perpetual economic subordination. The contrary thesis that advanced industrial countries have had to deal with increased competition arising from quite widespread diffusion now seems more plausible.
