In Gong (2015) "HIV Testing and Risky Sexual Behaviour", the author finds that people who discover they are HIV-positive increase risky sexual behaviour. This result is consistent with the prediction of the standard model so long as: 1. People experience disutility from potentially harming others 2. People who are HIV-positive are risk-seeking to begin with 3. People who are HIV-positive change their risk preferences 4. A person's expected costs of risky sexual behaviour decrease (relative to the benefits) when they find out they are HIV-positive.

Problem 1 Consider the following plant: G(s) = (10)/(s^2 - 1.5s + 25). Use MATLAB's rlocus command to answer the following questions: 1. Can this plant be stabilized with proportional control? 2. Can this plant be stabilized with a lead controller of the form C(s) = K(s + 5)/(s + 50)? 3. Choose the parameter K in the lead controller such that the percent overshoot for a unit step is 10 percent. Note that clicking on the loci in an rlocus plot will show various parameters including the percent overshoot. 4. Plot the step response of the closed-loop system. Is the percent overshoot near the desired value? If the percent overshoot is considerably different than the desired value, offer an explanation. Problem 1 Consider the following plant: G(s) = 10.
