1d) You have $100 to invest and are wondering where to put it. You are considering whether to buy your favorite stock (B) or put it in your couch (C), either decision occurring today. You know the stock price today, conveniently enough $100 per share, but you don’t know the stock price tomorrow. For simplicity, it could either be double ($200) or nothing ($0), with the probability of double being ?, and the probability of nothing being 1−?. If you invest in your couch you get your $100 back tomorrow. Your discount factor is ?, and you are risk neutral (i.e. your payoffs only depend on time discounting and money.)

Given: Part (b)

Given that the investor is risk neutral he will only invest in the stock if the present value of the stock is greater than the present value of the investment in the couch i.e. PV1 = PV2 Solving both sides of the equation to get the value of p we get: p = 1/2 or the value of p should be greater than 0.5

Suppose ? is greater than your answer in part (b). Martha Stewart knows what the stock price is going to be tomorrow, and offers to sell this information to you. You trust that she knows and is being honest because her written offer is finely hand-crafted using everyday household items. Assuming your only concern is making money and discounting for time (instead of moral qualms, or going to prison),

How much would you be willing to pay for this information?

Consider a high energy photon interacting in tissue. The photon first interacts via pair production before undergoing a Compton Interaction. The positron from pair production undergoes annihilation at the end of its life (no longer in-flight). One annihilation photon undergoes a Compton interaction and scatters at an angle of 100 degrees.

Calculate the kinetic energy of the scattered photon.

Chapter 18. Personality Disorders

Case Study

Cecelia Walker is a 24-year-old Caucasian woman who appears pale with dark circles under her eyes. She is clean, with her hair neatly arranged, and wearing clothing that appears shabby and too big for her. She has an elastic bandage on her left arm. She has been referred to the mental health clinic by her primary care physician because of symptoms of anxiety and worrying that have not responded to antidepressant medications. When asked what has brought her to the clinic, she says that she can’t sleep. On questioning, she says that she has no health problems but then says that some days she does not have enough energy to do the cooking, cleaning, and laundry during the day and to do the bookkeeping for her husband’s business in the evening. She thinks she may have lost weight.

In response to further questioning, Cecelia says that her first husband was killed a year ago during military service. They had married as soon as she graduated from high school and she had moved away from her family, which had always been very protective of her, to the condo that her husband owned. He had been the one to make all the decisions and to pay the bills. When she had learned of his death, she had been overwhelmed with grief and terrified at the thought of taking care of herself and their 4-year-old son, Tommy. One of her husband’s friends, Jake, was helpful during the days following her husband’s death, and she had felt safe with him. After 6 months they were married, and at first she had felt cherished and cared for, but then things begin to change. Jake controls the finances and gives her very little money for groceries and none for herself. He does not allow her to visit her sister or any of her old friends. She says that she tries very hard to be a good wife so that he won’t get angry and leave her. When asked about her arm, she says that Jake had become very upset when he found her talking to her sister on the phone and had grabbed her by the arms and shaken her. She adds, “He said that I deserved it.” She lowers her head and adds, “But he cares for me. He bandaged it for me.” She sighs, “I will have to try harder to do what he wants so that he won’t get mad at me or Tommy.”

QUESTION 9

1. Instructions: Please read the passage below, then answer the questions that follow.

   ------------------------------------------------------------------------------------------------

   Zoey wanted to buy a new car but was having difficulty deciding what kind of car to buy. She was feeling anxious and wanted to make a decision soon. It was a very cold day in January, and she was preparing for a long day; so Zoey decided to wear her glasses, a long pea coat, and her work satchel. Zoey had conducted some research and was pretty certain of the vehicle that she wanted. Zoey visited some local car dealers and asked for the advice of some of her friends. The salesmen at the dealerships were all very nice and seemed knowledgeable about the car that she was considering. Zoey found this to be surprising because the stereotype of a “car salesman” is that they are manipulative and will try to cheat you out of your money. However, Zoey wasn’t worried about being taken advantage of because she tends to think critically before making decisions.

   During her car search, the first salesman asked if she was a teacher. Zoey was offended by this, because she is a musician and looks nothing like a teacher! The second salesman asked her if she would be making a purchase without her husband, which also irritated Zoey. Finally, Zoey made a decision with the third dealer that she visited and purchased her vehicle. What eventually won her over is that the salesman spoke in simple terms, complimented her on how intelligent she was, and offered her a deal that the sales manager agreed to.

   Zoey would be considered creatively intelligent based on the information listed about her.
