Describe the career criminal perspective. Why did critics believe that “career” was a poor metaphor?

EDIT:
(The idea of career criminality is based on the assumption that some criminals are committed to a life of crime. In other words, they have a worldview built around criminal activity. They define themselves as criminals and tend to associate with other criminals.)

An investor's utility function for money (Bernoulli utility function) is the square root of money: u(x)=√x. Her decision making can be modeled by assuming that she maximizes her expected utility. Her current wealth is 100. (All quantities are in hundreds of dollars.)
She has the opportunity to buy a security that either pays 8 (the "good outcome") or loses 1 (the "bad outcome"). She can buy as many units as she wishes. For example, if she buys 5 units, she gets 40 in the good outcomes, but loses 5 in the bad outcome. The probability of the good outcome is 0.2, and the probability of the bad outcome is 0.8.
In answering the questions below, you may use Excel to find your answers, if you wish.
Will she buy any of this security? If yes, how much exactly?
If her wealth were 150, would she buy any of this security? If yes, how much?
If her wealth were 200, would she buy any of this security? If yes, how much?
Suppose that a tax of 50% is imposed on this security. This means that whenever she gains 8 from the security, she gets to keep only 4. However, whenever she loses 1, she actually gets back 0.5, i.e. she only loses 0.5 (because her capital loss is tax deductible). If her initial wealth is 200, will she buy more or less of this security than in question 3?
Write a few sentences summarizing what you learned from answering the four questions above.
Please answer all questions in enough detail for me to see exactly how you got to your answer. Submit both your answers and how you found them. You may use Excel to find your answers. If you do so, please attach the relevant file.

Suppose that the company could expand its labor capacity by running an extra shift that could provide up to 19,000 more hours. The direct labor cost would increase from $18 to $22 per hour for all hours of direct labor worked during the extra shift. What additional product(s) should Austin manufacture and what additional profit would be expected with the use of the added shift?

Austin Should Manufacture =

Additional Profit Would Be =
