Character development of Shukhov in One Day in the Life of Ivan Denisovich
Character development of Shukhov in "One Day in the Life of Ivan Denisovich" Ivan Denisovich Shukhov, the protagonist of the novel 'One Day in the Life of Ivan Denisovich' is a prisoner in the Soviet prison camp. He was caught by the Germans during the Second World War with perfidy when he tried to come back to Soviet lines. He spent earlier time of his imprisonment in Ust-Izhma camp and then in the "special" political camp. The special political camp was in the hands of harsh and abrasive authorities. Shukhov has spent eight years and he has enough experience of most of the tricks that can be used in the camp for the survival. He knows all the legerdemain of the harsh camp system, how to get extra food or other favours but he sticks to his moral principles of doing things so that there would be no harm for his self-respect. He actually adapts his own ways of survival in the camp. Shukhov was a farmer when he was in his home, in his own free life he used to think about the farming, buying horses and haymaking etc. It shows his agricultural experience and also shows his hard working life of being a farmer. As his life starts to move on, his carriers and thinking also changes with respect to his position. Then he became soldier of the Second World War but after that he could not go to his free living life of farmers and captured by Germans. Now, the life and thinking
How do Medea and Hedda Gabler combine tradition and unconventionality within their roles as women in a constraining society?
How do Medea and Hedda Gabler combine tradition and unconventionality within their roles as women in a constraining society? The eponymous characters featured in both Medea and Hedda Gabler have perpetually been cast as unconventional women, defying every aspect of feminine behaviour expected of them in their respective societies. However, in truth, both women conform to convention far more than it would seem, albeit in contrasting ways. Medea dreams of the same future as any ordinary Greek woman would even despite her refugee status. In the end it is circumstances that drive her to the unexpected and terrible acts she commits. Hedda differs within her relationship with the culture surrounding her and fights at it. She is forced to live the life of a traditional woman in her society and hates it, as we shall see, she makes any effort she can to escape it. This combination of propriety and unconventionality contribute to the power of both plays as tragedies. There is some debate, though, on whether the playwrights intentionally did this, or, due to the cultural era they inhabited, they could not possibly see women totally unshackled from their roles in society. Medea appears to be a traditional wife in many ways therefore the cataclysmic breakdown of her marriage with Jason is more of a surprise to the reader; the way in which it dissolves into such violence. Throughout the
Pourquoi zola compare-t-il ses personnages a des betes humaines?
Pourquoi Zola Compare-t-il Ses Personnages A Des Bêtes Humaines? Émile Zola - un écrivain du ixième siècle et pionnier du Naturalisme - a reçu beaucoup de critique pendant sa carrière littéraire à cause de son écriture innovatrice. Dans son œuvre Thérèse Raquin il décrit avec une précision méticuleuse un "dame violent" d'adultère, du meurtre et du suicide. Selon Zola, qui déclare dans la préface de la deuxième édition de Thérèse Raquin, "pas un des pudiques journalistes qui ont rougi en lisant Thérèse Raquin lui paraît avoir compris ce roman". Mon but pour cette dissertation est d'essayer de comprendre ce roman, c'est-à-dire je vais considérer pourquoi Zola a comparé ses personnages à des bêtes humaines en employant une approche scientifique et pourquoi il a voulu étudier les tempéraments au lieu des caractères. En fait le Naturalisme, c'est un genre de la littérature selon laquelle on essaye de considérer les êtres humaines comme des objets pour pouvoir aller plus loin que simplement les observer (comme dans la plupart de la littérature) mais les étudier. Dans Thérèse Raquin Zola a traité ses personnages plutôt comme des produits chimiques dans une réaction - avec des propriétés prédéterminées qui vont toujours réagir de la même façon (souvent violent) - et non comme des vraies êtres humaines. Zola a donné aux amants
LEDCs are more vulnerable to hazard events than MEDCs. Discuss.
"LEDCs are more vulnerable to hazard events than MEDCs. Discuss." Natural hazard events occur all throughout the world and subject many people to negative impacts, however in different degrees due to certain factors which depend on the countries affected themselves. Impacts of such hazard events can be classified into three categories, namely social, economic and environmental impacts. These impacts can vary spatially or temporally - depending on the area subjected as well as the span of time the disaster lasts for, affecting assessment of vulnerability. Vulnerability is defined as the conditions that increase the susceptibility of a community to a hazard or to the impacts of a hazard event. Deciding whether some impacts are greater than others in terms of vulnerability is difficult due to this variation, however the extent of impact is often influenced by the wealth of the area which the hazard event is subjected upon - LEDCS are less economically developed, and usually have little capital to start off with, leaving even less on the technology that is often more readily available in MEDCs, the more economically developed countries, making the population in the former already more vulnerable than the latter. However, this does not prevent hazards from occurring in MEDCs and the monetary status of a country cannot influence the magnitude or frequencies of hazard events, two
The effect of temperature on amylase activity
Kiu Yi, IP 13M The effect of temperature on amylase activity Introduction The purpose of this experiment is to investigate if temperature will affect the amount of starch broken down as enzyme activity can change by different temperature. This is because as temperature rises the rate of chemical reactions increases due to the temperature increases the rate of the molecules' motion. More interactions will be existed between an enzyme and its substrate. The enzyme used in this lab exercise is amylase, which is commonly found in saliva and germinating seeds, catalyzes the breakdown of starch. It also reacts quickly when heat is present during the process of it reaction. However, if the temperature is higher than the optimum point, enzymes can be denatured and they can no longer bind to a substrate and catalyze reactions. My hypothesis is therefore the amylase activity would increase as the temperature rise, until a certain high temperature at which the amylase would denature and be non-functional. In this experiment, I will observe the activity of amylase by using iodine as iodine reacts with starch to form a dark brown/purple color. After adding in iodine, when amylase breaking down starch, less and less starch will be present and the color of this solution will become lighter and lighter. Equipments • 0.1% Amylase 0.5 ml • 1% Starch 5ml • 10 Test tubes and
Tropical Rainforest Case Study
Sasha Zouev IB, 16/11/05 Tropical Rainforest Case Study, Amazonia Introduction Tropical rainforest, temperate coniferous and deciduous woodland forests are the three main categories of forest type. Tropical rainforests are considered a much richer species that the other two, and temperate vegetation is one that grows fastest. The rainforest ecosystem is very weak and easily unbalanced, making this type of forest more "permanently destroyed" than the other two. The importance of tropical rainforests lies within the fact that they are the earth's richest source of life as they play a vital part in the earth's natural cycles of soil, water and air through the process of photosynthesis. In this case study we will be looking closely at the tropical rainforest in the Amazonia region of South America. Where is this Rainforest? The term, Amazon rainforest, is used to basically talk about the moist and broadleaved region of what is known as the Amazon Basin, which is around 7 million km squared and covers areas of mainly Brazil, Colombia, Peru and many more South American countries. This rainforest accounts for around 50% of the world's remaining rainforests. Amazonian rainforests contain the biggest and most species-rich tract of tropical rainforest that there is to be found. It is the world's greatest natural resource - the most powerful and bio-actively diverse
Examine the causes and the effects of biodiversity loss in the Tropical Rainforests
Examine the causes and the effects of biodiversity loss in the TRF Biodiversity can be defined as the variety of all forms of life on earth (plants, animals and micro-organisms). The tropics are the richest areas for biodiversity as tropical rain forests contain over 50% of the worlds species in just 7% of the worlds land. They account for 80% of the world's insects and 90% of its primates. Even though biodiversity benefits us humans in countless ways we tend to be oblivious to this fact and instead, the biodiversity on earth is gradually diminishing. There are many reasons for the loss of biodiversity and the most prominent include Globalization & Cattle Ranching, Hydroelectric Power (HEP), Migration and Logging. Similar to how there are numerous causes for the loss of biodiversity, these causes also have many drastic effects. As mentioned in the introductory paragraph, globalization and cattle ranching is one of the major causes for the loss of biodiversity. Globalization can be defined as the world coming together for trading purposes. This contributes to the loss of biodiversity as globalization is directly linked with deforestation. For instances, huge global corporations like McDonalds own countless amounts of cattle which are often located in deforested areas. In addition to this, much forest land in the Brazilian Amazon is also deforested in order to enable the
Population Case Study - Japan
Sasha Zouev Geography IB, 13/09/05 IB Case Study: Japan (MEDC) Population, Distribution, Density Introduction: Japan is a great example of an MEDC with a particular population pattern and distribution. The country, located on the western edge of the Pacific Ocean lies to the east of Asia and is made up of about 3,000 smaller islands. There are several large main islands including, from top to bottom, Hokkaido, Honshu (the biggest), Shikoku and Kyushu. Japan is also interestingly rated 10th in the world by population count and has an area of about 377,835 km². The aim of this case study is to examine, section by section, the different factors that affect Brazilian population growth and distribution by looking at areas such as geographical positioning, politics, history, and generate some sort of conclusion Distribution: Japan's population is mostly concentrated alongside the south and west coast (figure 1). Japan's population density is ranked 18th in the world, and has assisted in advertising very expensive land prices. From the years 1980 to 1987, prices of land in the six largest cities nearly doubled. This prevents many poorer families from ever purchasing or renting housing in the central cities. Because of this, daily transportation for many workers became a real lengthy hassle. For example some daily commuters had to travel up to four hours total to reach
How far do Trotsky(TM)s own misjudgments account for his failure in the power struggle which followed Lenin(TM)s death?
"How far do Trotsky's own misjudgments account for his failure in the power struggle which followed Lenin's death?" Following Lenin's death in 1924, a power vacuum appeared for the leadership of the Communist Party in Russia. A collective leadership was proclaimed, however competition for individual authority between Trotsky, Stalin, Kamenev, Zinoviev, Bukharin, Rykov and Tomsky led to a fierce struggle for power, ending in Stalin's triumph and the beginning of his tenure as the leader of the Communist Party. The strongest contenders in the power struggle were Stalin and Trotsky, however a number of unfortunate decisions and lack of support on Trotsky's part, coupled with Stalin's tactics and power base, led to Trotsky's defeat and exile. It was the latter of the two factors that contributed more to Trotsky's ultimate failure, due to the fact that Stalin's initial position was stronger, and his opportunism allowed him to take advantage of Trotsky's misjudgments, thereby allowing him to take power. However, it is worth noting that the term 'misjudgments' is relative to the historian, since a number of Trotsky's unsuccessful decisions were deliberately made to avoid certain outcomes, therefore cannot accurately be termed 'misjudgments'. Trotsky, although he had a limited power base made up of mostly radicals and students, was in a position of adequate leverage immediately
