Managerial accounting.This case examines the role of business in South Africa's historic transition away from apartheid to popular sovereignty. The case provides a previously untold oral history of this key moment in world history, presenting extensive video interviews with business leaders who spearheaded behind-the-scenes negotiations between the African National Congress and the government. Faculty teaching the case have used the material to push students to consider business's role in a divided society and ask: What factors led business leaders to act to push the country's future away from isolation toward a "high road" of participating in an increasingly globalized economy? What techniques and narratives did they use to keep the two sides talking and resolve the political impasse? And, if business leadership played an important role in the events in South Africa, could they take a similar role elsewhere?

Question 37 Is there a basis for treating patients for filariasis according to the eosinophil count (except for cases of tropical pulmonary eosinophils; TPE)?

Question 38 Why do patients who ingest eggs from a tapeworm in contaminated food not develop tapeworms?

Question 39 I have a query about one of the details in the book. You mention that perihepatitis is a feature of gonorrhoeal infection, but other books say that perihepatitis (Fitz-Hugh-Curtis syndrome) is a complication of chlamydial infections. Is there a possibility of perihepatitis in gonorrhoea? Thank you.

Question 40 In the 7th edition of Kumar and Clark Clinical Medicine, you indicate that there is no benefit in treating the male partner of a woman diagnosed with bacterial vaginosis (BV). As many physicians use the 2 g 1 metronidazole dose, is this unwarranted? Does it differ in women experiencing frequent recurrences of infection?
