Homework 5: Sigmund Freud

    Freud’s general theory of personality is called ___________________ theory. While working with patients experiencing conversion disorders, Freud became convinced that all such cases were caused by unexpressed sexual motives.

    Freud viewed the mind as being composed of the three parts. The ___________________ functions entirely at the unconscious level and operates according to the ___________________ principle, which attempts to satisfy its needs by using wish-fulfilling mental images. A second part of the mind is called the ___________________, which can be thought of as the executive of personality and helps us to deal with the world through the reality principle. The only part of the mind containing a sense of morality is the ___________________, which is created mainly by parents. Parental punishment creates the moral inhibitions called conscience, whereas parental rewards establish a standard of conduct called the ego ideal.

    Freud believed that our personalities are formed as we pass through a series of developmental stages from infancy to adulthood. Stressful events experienced during a stage can leave the personality ___________________ at that stage. According to Freud, the developmental stages result from a shifting energy from one ___________________ zone to another. Since these stages represent the release of sexual energy, they are called ___________________ stages. The first stage, lasting from birth to one year of age, is called the ___________________ stage. If a person becomes fixated in the oral stage, he or she may engage in overeating and drinking.

    The second stage of development, from one to three years, is called the ___________________ stage. Fixations at this stage may lead to a personality that is either stingy and compulsive, called ___________________ ___________________, or cruel and disorderly, called ___________________ ___________________.

    From ages three to six, children are in the ___________________ stage, in which the genitals become the primary source of pleasure. During this stage, boys develop a sexual attraction to their mothers, referred to as the ___________________ ___________________. Boys also develop a fear of their fathers, called ___________________ ___________________. Girls develop desires for their fathers called the ___________________ ___________________. According to Freud, failure to resolve the phallic stage results in a phallic personality, characterized by egocentric selfishness, impulsiveness, and a lack of genuine feeling for others.

    From ages 6 to 11, children enter the ___________________ stage, during which sexual interest is relatively inactive. From age 11 through adulthood, the individual is in the ___________________ stage, in which sexual and romantic interests are directed towards one’s peers. Most modern revisions of psychoanalysis agree that Freud overemphasized ___________________  motivation, underemphasized positive aspects of personality and the importance of relationships, and was prejudiced against women.

Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p. Of 125 adults selected randomly from one town, 31 of them smoke. Construct a 99% confidence interval for the true percentage of all adults in the town that smoke.n

Suppose that a small town has seven burger shops whose respective shares of the local hamburger market are​ (as percentages of all hamburgers​ sold): 22 ​percent, 22 ​percent, 18 ​percent, 11 percent, 10 ​percent, 9 percent, and 8 percent.

The​ four-firm concentration ratio for the hamburger industry in this town is (?) percent. ​(Enter your response as a whole​ number.)

What is the Herfindahl index for the hamburger industry in this town?

If the top three sellers combined to form a single firm, what would happen to the four-firm concentration ratio and to the Herfindahl index?

One of the major problems in Latin America in the 1980s was according to some economists, the wager igidity. The wages were not falling down fast enough when economic conditions were demanding such a fall according to those economists. What could be a remedy those economists might have suggested to
decrease the wage rigidity?

1. Market demand for laptop computers is y = 500 - p. But the computers are developed by a hardware firm with a cost function c(y) = 100, & the operating system is developed by a software firm with a cost function of c(y) = 150. a. Calculate the optimal prices for the hardware & software firm to charge, & the total market quantity. (4 points) b. Calculate the optimal price & quantity if it were to behave like a merged firm

There are nine firms in industry X. The first firm’s sale is $300,000, the second firm’s sale is $250,000, the third firm’s sale is $200,000, the fourth firm’s sale is $150,000. There are 5 other firms, each generates sales of $80,000.

1. Calculate two measures of concentration.

2. If the second and third firms merged together, recalculate the two measures of concentration and determine whether the merger caused a higher concentration or not?

MergeSort has a rather high memory space requirement, because every recursive call maintains a copy of the sorted subarrays that will be merged in the merge step. What is the memory space requirement in terms of O(.)? Describe how you would implement MergeSort in such a way that merge is done in-place and less memory space is needed? In-place means MergeSort does not take extra memory for the merge operation as in the default implementation.

World Enterprises is determined to report earnings per share of $3.20. It therefore acquires the Wheelrim and Axle Company. There are no gains from merging. In exchange for Wheelrim and Axle shares, World Enterprises issues just enough of its own shares to ensure its $3.20 earnings per share objective.

a. Complete the table below for the merged firm. (Do not round intermediate calculations. Round "Price per share" and "Price-earnings ratio" to 2 decimal places and other answers to the nearest whole number.)

b. How many shares of World Enterprises are exchanged for each share of Wheelrim and Axle?

Shares exchanged?

c. What is the cost of the merger to World Enterprises?

Merger Cost?

d. What is the change in the total value of the World Enterprises shares that were outstanding before the merger?
