diversification among the 20 stocks that remain in his portfolio. This entails maintaining a low correlation among the remaining stocks. For example, in part (a), with ρ = 0.2, the increase in portfolio risk was minimal. As a practical matter, this means that Hennessy would have to spread his portfolio among many industries; concentrating on just a few industries would result in higher correlations among the included stocks. 2. Risk reduction benefits from diversification are not a linear…

Starting off with Marx concept of alienation, alienation is the dehumanization of wage workers. There are four aspects of alienation , first workers are alienated from the product of their labor, second, they are alienated from the means of production, thirdly, their own being ,and lastly dehumanized from society. When workers are alienated we become less and less attached with ourselves”. For Marx, alienation is inherent in capitalism, because the process of production and the results…

How does this relate to world politics? The very core of Marxism is the unit of analysis, most theories of IR today assume the state to the main actor, not only that, but to be an autonomous, rational actor, totally independent of social relations like a ‘black box’. Marxism, on the other hand contends it is the class system which is the key to understanding world politics. Furthering this perception; with the new neo-liberal world order replacing the embedded liberal order which centred on the…

When conducting a hypothesis test for the difference between two means it’s essentially called a two sample t-test. According to Dr. Mirabella (2011, p. 5-2) states that, “In each case you can conduct a t-test for independent means to determine if a significant difference exists.” Furthermore, we’re conducting this test to see if there is an overlapping or if there is clearly a difference among the GPAs for men and women. In our case we are comparing the GPAs for a sample of men and a sample…

the four seasons, humid environment, rainy winter weather and the prevailing wind is south and southwestern (Amer and Abou Hamed 2011).

Workers are alienated by the bourgeoisie who own the means of production. Marx’s identifies four types of alienation. The first is the alienation of the workers…

Metamorphosis by Franz Kafka tells the story of Gregor Samsa, a man who wakes up as a giant cockroach one morning and the self-realization he goes through as a non-human being. This tale is analogous to Karl Marx’s theories about capitalism and alienation since these theories state the issues with the capitalist system and the effect work has on individuals. For instance, Karl Marx’s theories about alienation of the worker states that workers are alienated from other human beings, producers are…
