Acid rain - Research Paper ExampleIt appears to change the characteristics of the milieu on a planetary scale therefore, the global ecological crisis is dangerous to the worlds population. Dealing with global environmental crisis is complicated due to the detail that it requires the cooperative actions of the whole world, rather than the individual actions of the certain country or population group. It needs to minimize the pollution produced by mankind to the levels that the nature cease cope with it on its own. Currently, the global environmental crisis consists of two main components acid rain, the greenhouse effect, pollution with super toxicants, and the ozone holes. In the current paper we are pass to discuss the phenomenon of acid rain and its effects on nature and humanity.The term acid rain was introduced by Robert Smith, English engineer, in his book Air and precipitate The Beginning of a Chemical Climatology (1872) (Myers 267). Acid rains containing solutes of sulfuri c and nitric acids cause serious damage to nature, because soil, water, vegetation, animals, and people become their victims. Gases that are released by burning of dodo fuels, among others, are composed from dioxins of sulfur and nitrogen. Depending on the composition of a certain fuel there may be more or less of these dioxins. displace oil and sour coal provide the most saturated sulfur dioxide emissions. Tons of sulfur dioxide emitted into the atmosphere resulting from chemical reactions turn into weak acid solution. In the internal combustion engines and boiler systems, nitrogen and oxygen under high temperatures form the nitrogen oxides. In this respect, energy production is accompanied by oxidation of the environment. Emissions are dispersed over vast areas due to the height of the power plant pipes (Granier, Artaxo, and Reeves 54).The acidity of the water solution is determined by the presence of positively charged hydrogen ions H+ in it and

Literature - Essay Examplethe lower social status of Atieno as compared to the speaker, the power struggle between the speaker and Atieno and the misery of the characters represented.In focusing on the different social status of the characters represented in the poem, the critic ordain point out the various ways in which Atieno is essentially a slave to her older and more successful relative. This difference in social status equates to a significant difference in expected responsibilities as Atieno, at only 8 years old, is expected to perform all the basic functions of the field of operations making it possible for the speakers wife, the childs aunt, to sit all day and sew. This gives the impression that the wifes chores are not as heavy or as tiring as those given to the niece. This kind of difference in expectations is what Marx points to when he indicates that the lower classes will rise up against perceive injustices in the division of labor to reward.The Marxist critic is al so likely to focus on the apparent power struggle occurring between Atieno and the speaker as a result of these differences in labor expectations. The girl is covetous towards her cousins things, she spends too long at market (26) and is evidently given a place to balance but not the same access to education that her cousins create. This idea is given voice as the speaker asks, Dont I keep her, check my own ones / Pay the party, union fee (20-21). Because she has no power of her own and no real chance of escaping her situation, Atieno rebels against her system the only way she knows how. This speaks directly to Marxs theory that when the laboring classes have finally had enough of capitalist gain being withheld, they will cease to perform until more equitable terms have been made available.Finally, the Marxist critic is likely to take a look at the misery of the lower classes as it is reflected in the lives of all the characters mentioned. Although Atieno is obviously the worse-o ff among

The Main Principles Of Learning And The Action Theory Essay

The Main Principles Of Learning And The Action Theory - Essay ExamplePrinciples of schooling are derived from the following learning theories action, cognitive-gestalt, experiential, facilitation, holistic, reinforcement, sensory stimulant drug learning theory. In this respect, we shall analyze them according to the theories they are most tightly interwoven with. The main principles of learning based on the action theory farming that no effective learning loafer be presented without proper action-application experience. In most cases small action learning sets** are created in order to give the learners an chance of applying their knowledge on practice, making mistakes and learn from them without having to deal with unwanted consequences of their decisions. Cognitive-gestalt learning is based on insights and problem-solving. However, unlike the first theory, it puts stress on the learners individual ways of interpreting problem situations.Experiential theory speaks of a four-sta ge process of learning material (concrete experience, active experimentation, abstract conceptualization, observation, and reflection). A great eudaemonia of this theory is that despite all of the stages are being necessary, an individual can choose (consciously or subconsciously) the most suitable one to contribute more efforts to it. Besides, stages can be repeated one by one as many times as it takes to exclude all of the mistakes.Principles of learning used in a facilitation theory are based on the acknowledgment of the fact that a human being is naturally eager to learn and perfect oneself. Thus, here learning process includes polemics with a teacher in an attempt to find as many answers as possible and, what is more important, to research a topic alternatively of simply remembering the facts given. Such an approach is commonly used in humanitarian education.

Raisin in the Sun by Lorraine Hansberry Term Paper

Raisin in the Sun by Lorraine Hansberry - Term Paper ExampleAdapting a classic piece of literary productions into film is a sophisticated task.The adapter has duel responsibility. On one side,he or she has to preserve the originality of the classic and on the other,he/she must be able to glide by the real meaning of the piece of literature. Utilizing a verity of techniques Daniel Petrie, the film director of the film , A Raisin in the Sun(1961) did not solo preserved the originality of the play, but also successfully transferred this classic of Afro American literature into a highly commendable film. Let me first discuss those adaptation techniques briefly. There are seven ways in which an adapter can transpose a play into movie (Desmond and Hawkes, 2006). These are visualizing the set, lighting, casting, musical tones, symbols and motifs, camera angles, and shot length. However, a creative filmmaker would not curse upon just one technique and would employ a variety of tools to make a movie engaging. Daniel Petrie used creative frame composition and shot discrepancy to communicate the strong and shared emotions within the Younger family. Further, he brings the climax of the movie by capturing facial expressions of the characters in a close up. Moreover, he added or omitted various scenes and dialogues during the process of adaptation in order to make the flow of the film . Similarly, he creatively used music to communicate the real flavor of the characters and to move his audience In A Raisin in the Sun, the strong shared emotions and relationship of the black family play an strategic role to the overall development of the plot. The director communicated this emotional empathy with a creative series of shots and compositions that visually represented the shared emotions. Through the employment of this technical cinematic method, Petrise actually emphasized many important scenes of the play in his film. For instance, in Act Two, Scene One of the written play, for the first time in film, he uses frame composition to share the corporate family emotions. In fact this scene communicates a wide range of feelings. When mammy shares her purchase of the house in a better neighborhood, she herself and Ruth seems relieved and satisfied. irrelevant to both the women, Walter not only seems angry and despairs but his dream of opening liquor shop seemed sunken. However, on the other hand Mama herself shows fear of the Walters possible reaction towards her decision. Screenplay script runs with an array of emotions and the filmmaker successfully expresses those emotions visually. The director utilized camera perfectly to capture those changing emotions on the actors faces. For example, Walter mood changed from suspicion to dissatisfaction on hearing that the money has been used to buy a house instead of its investment in business. On the contrary, Ruth was extremely happy. But when Mama told them the location of the house, Walter became angry w hile Ruths frame of mind changed from joy to worry. Thus apart from dialogues, film depicts a vast spectrum of emotions through visuals. Petrise pickaxe of using face-close-up is really effective. Petrise uses camera angle to create emotional effects. In Scene Three of Act two, he uses mirror to reflect Walters inside conflict . The camera cuts back and forth between Walter and Mr. Lindner. Through this technique, the director not only intensified the emotional meanings of the scene but also reflects Walters changing understanding of Mr. Linder offers. Film is a visual media therefore it is always preferable to rely upon emotions for the climax instead of dialogue (Duncan, 2006). Petries another smart quality is his exposition of climax through emotions rather than dialogues. These are the emotional moments when Bobo reveals about Willys run away along with their investment. This is disturbing news not only for Walter and Bobo, but for all the Youngers. During these critical mome nts Petries framing Ruth into the scene is an ingenious choice as her reaction on such news is what viewing audience want to note. Moreover,
