2. (Maximum length one page.) Consider a strange infectious disease that infects cows and people. Cows live in a fenced pasture and spend their days wandering around aimlessly munching on grass; College students live like normal college students: some are more social than others, some study in isolation and others study in groups, etc.... Suppose that we examine the number of interactions of the cows and the students and find that the average number of interactions across which this infectious disease can spread is the same. a) Explain how epidemiologists use the concept of the reproduction number, R, and how R will differ across these two populations. In your response, be sure to state a definition for R; how Kucharski's DOTS framework can be used to understand R; and how it is used to understand infectious disease dynamics. b) How does the epidemiological concept of dispersion relate to R? How does it relate to superspreading and Pareto's "80-20 rule?" c) Based on the information about the cow population given above and our discussion of the social networks of people from class, will the cows and students have the same values for dispersion? How do you expect that they will differ? Why? d) Considering only the interaction effects within this question, which population is more at risk of a very large outbreak of this disease? Why?

8. The Canadian National Advisory Committee on Immunization (NACI) recommended against vaccinating the whole population against the smallpox virus because the vaccination has undesirable, and sometimes fatal, side effects. Suppose the accompanying table gives the data that are available about the effects of a smallpox vaccination program. Percent of population vaccinated 0% 10 20 30 40 50 60 Deaths due to smallpox 200 180 160 140 120 100 80 Deaths due to vaccination side effects 0 4 10 18 33 50 74 a. Calculate the marginal benefit (in terms of lives saved) and the marginal cost (in terms of lives lost) of each 10% increment of smallpox vaccination. Calculate the net increase in human lives for each 10% increment in population vaccinated. b. Using marginal analysis, determine the optimal percentage of the population that should be vaccinated.

Becky and Sarah are sisters 1who share a room. Their room can easily get messy, and their parents am always telling them to tidy it. Here are the costs and benefits to both Becky and Sarah, of taking the time to clean their room: If both Becky and Sarah clean, they each spends two hours and get a clean room. If Becky decides not to clean and Sarah does all the cleaning, then Sarah spends 10 hours cleaning (Becky spends 0) but Sarah is exhausted. The same would occur for Becky if Sarah decided not to clean—Becky spends 10 hours and becomes exhausted. If both girls decide not to clean, they both have a dirty room. What is the best outcome for Becky and Sarah? What is the worst outcome? (It would help you to construct a prisoners dilemma table.) Unfortunately, we know that the optimal outcome will most liker not happen, and that the sisters probably will choose the worst one instead. Explain what it is about Beckys and Sarahs reasoning that will lead them both to choose the worst outcome.

a) What is the island's maximTwo fields can be planted on Robinson Crusoe's island. Each can be used to grow oranges or apples. If Field A is planted entirely with oranges, it will produce 2 bushels (bu.) of oranges. If A is planted entirely with apples, it will yield 4 bu. of that crop. For Field B, the numbers are reversed: B will produce 4 bu. of oranges if entirely planted with oranges, or it will produce 2 bu. of apples if entirely devoted to that crop. IF A FIELD IS SPLIT BETWEEN THE TWO CROPS, the output of each crop from that field will be proportional to the fraction of the field planted in that crop. For example, if half of B is planted with each crop, then it will produce 2 bu. of oum possible output of oranges? __________ b) Graph your answer in a) on the axes found on the next page and label it point H..(Put oranges on the horizontal axis and apples on the vertical axis) c) What is the island's maximum possible output of apples? __________ d) Graph your answer in c) on the…

You were on the schools swimming pool to practice your butterfly stroke for an upcoming competition and are the only one in the pool area when you noticed someone floating in the pool's 8ft area.
