1. Citing the Digital Millennium Copyright Act (DMCA), Airbnb is challenging the New York law and others in the United States, arguing that it merely operates a digital marketplace, and thus is not responsible for the content that users place on its site. Do you think Airbnb has a strong argument? Why or why not?

2. Are you concerned that the concept of the sharing economy could be abused by unscrupulous “entrepreneurs” and thus give the entire novel concept a bad reputation? Why or why not? Explain.

A boy standing on top of a building throws a small ball from a height of H₁ = 45.0 m. (See figure.) The ball leaves with a speed of 26.9 m/s, at an angle of 61.0 degrees from the horizontal, and lands on a building with a height of H₂ = 12.0 m. Calculate for how long the ball is in the air. (Neglect air friction, and use g = 9.81 m/s².)

Wicked Problems: Characteristics

Conklin offered a set of six defining characteristics:

1. You don’t understand the problem until you have developed a solution.

2. Wicked problems have no stopping rule.

3. Solutions to wicked problems are not right or wrong.

4. Every wicked problem is essentially unique and novel.

5. Every solution to a wicked problem is a ‘one shot operation.’

6. Wicked problems have no given alternative solutions.

Explain an example of a wicked problem and justifications why it can be considered a wicked problem and how it satisfies each of the above characteristics.

Problem 1. A boy has a fever after coming home in the afternoon. His mother thinks that it could be related to the following three possible reasons: A : He plays football in the rain, B : He takes a cold water shower after playing, C : He eats too many ice creams.

(iii) The mother has 80% confidence that her son’s fever is caused by at least one of the three reasons. She further estimates that the probabilities of the three individual reasons are 0.5, 0.5, 0.2 respectively, and she believes that they are pair- wisely independent. Are the three reasons mutually independent?

(iv) Suppose that the mother is 100% sure that her son’s fever is caused by at least one of the three reasons. Moreover, she believes that they are mutually inde- pendent although she doesn’t know the exact probabilities of any of the individual reasons. After a moment’s thought, she tells her son that one of the three reasons must be certain (that is, one of P(A) = 1 or P(B) = 1 or P(C) = 1 must be true)! Should the boy believe his mother’s assertion?

In the novel Never Let Me Go by Kazuo Ishiguro, children are raised in a boarding school to become organ donors for society. The children eventually find out they are genetic clones created for the expressed purpose of providing another individual backup organs to prolong that individual’s life. Are cloned life forms the same as the original of the copy? Do they have the same rights and privileges of individuality if they are genetically identical to someone else? How might our own history with copied things influence our perceptions and interactions with clones?

Dr. Stambaugh predicts that a novel antidepressant drug will effect memory. To examine this, the drug is administered to a random sample of 22 trained rats. The rats were then placed in a maze and timed on how long it took them to complete it. The average completion time was 47 seconds. Normal rats have a mean completion time of 45 seconds with a standard deviation of 11 seconds. What can be concluded with an α of 0.05?

a) What is the appropriate test statistic?
---Select one--- (na, z-test, one-sample t-test, independent-samples t-test, or related-samples t-test)

b)
Population:
---Select one--- (the maze, normal rats, time to complete maze, trained rats, memory)
Sample:
---Select one--- (the maze, normal rats ,time to complete maze, trained rats, memory)

c) Obtain/compute the appropriate values to make a decision about H₀.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
critical value =  ; test statistic =
Decision:  ---Select one--- (Reject H0 or Fail to reject H0)

d) If appropriate, compute the CI. If not appropriate, input "na" for both spaces below.
[  ,  ]

e) Compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and select "na" below.
d =  ;   ---Select one--- (na, trivial effect, small effect, medium effect, or large effect)
r² =  ;   ---Select one--- (na, trivial effect, small effect, medium effect, or large effect)

f) Make an interpretation based on the results.

a.Rats on the antidepressant drug were significantly slower in completing the maze.

b. Rats on the antidepressant drug were significantly quicker in completing the maze.    

c. The antidepressant drug did not significantly impact the rats in completing the maze.

You are a researcher in a biochemistry lab which investigates a novel, globular protein production by yeast. The director of the lab asks you to produce and purify the protein. Unfortunately, you could not obtain any information about if the protein is extracellular or intracellular. Within this scope, please propose a method/methods for isolating the protein after the production process. You have a well-equipped laboratory with the equipment would require to isolate and purify. In addition describe an experiment or set of experiments to prove (or disprove) the protein is composed of more than one subunit.
