Consider the settlement in U.S. v. Halifax and the Corporate Integrity Agreement entered into by Halifax Hospital Medical Center, which addresses methods for preventing Anti-Kickback violations. What measures required by the Corporate Integrity Agreement do you believe will be most effective in preventing future violations? Which, if any, do you think will be least effective or ineffective in preventing future Anti-kickback violations? Explain your reasoning.

Read the following scenario and in the lawsuit of Stella v McDonalds, list up to three arguments in favor of Stella and up to three arguments in Favor of McDonalds.

“I’m Stella Liebeck. I was in the car with my grandson one day, and he drove up to a McDonalds drive-thru. He asked me if I wanted anything. Of course I did! It’s McDonalds! So, I got a cup of coffee. Hey, I was 79. I needed a little caffeine. They handed him his order (Big Mac, supersized, and my coffee). He pulled over to the side of the line so I could add some milk and sugar. I had the cup balanced on my knees and took the lid off, and hot coffee spilled all over me! I spent 8 days in the hospital having skin cut off my body and grafted onto my knees to replace the burned skin! It was awful! My cotton sweatpants absorbed the coffee, scalding my thighs, buttocks, and groin. I suffered third-degree burns on six percent of my skin and lesser burns over sixteen percent. I lost 20 pounds (nearly 20% of her body weight), I lost so much weight I only weighed 83 pounds and had to undergo two more years of medical treatment.”

Given an undirected graph G=(V, E) with weights and a vertex , we ask for a minimum weight spanning tree in G where is not a leaf (a leaf node has degree one). Can you solve this problem in polynomial time? Please write the proof.

A negative charge, -q, has a mass, m, and an initial velocity, v, but is infinitely far away from a fixed large positive charge of +Q and radius R such that if the negative charge continued at constant velocity it would miss the center of the fixec charge by a perpendicular amount b. But because of the Coulomb attraction between the two charges the incoming negative charge is deviated from its straight line course and attracted to the fixed charge and approaches it. Find the closest distance the negative charge gets to the positive one.
