The Hearts and Hands Clinic has two service departments (Human Resources and Information Systems) and two "production" departments (In-patient Treatment and Out-patient Treatment). The service departments service the "production" departments as well as each other, and studies have shown that Information Systems provides the greater amount of service. Which of the following allocations would not occur if Hearts uses the step-down method of cost allocation? Select one: a. Human Resources cost would be allocated to In-patient Treatment. b. In-patient Treatment cost would be allocated to Out-patient Treatment. c. Information Systems cost would be allocated to Human Resources. d. Human Resources cost would be allocated to Information Systems. e. Both Human Resources cost would be allocated to Information Systems and In-patient Treatment cost would be allocated to Out-patient Treatment.

CASE: Promoting respect for universal human rights is a central dimension of many countries’ foreign policy. As history has shown, human rights abuses are an important concern worldwide. Some countries are more ready to work with other governments and civil society organizations to prevent abuses of power. Begun in 1977, the annual Country Reports on Human Rights Practices are designed to assess the state of democracy and human rights around the world, call attention to violations, and—where needed— prompt needed changes in U.S. policies toward particular countries.

Instructions: Find the latest annual Country Reports on Human Rights Practices for the BRIC countries (Brazil, Russia, India, and China), and create a table to compare the findings under the “Worker Rights” section. What commonalities do you see? What differences are there?

Design a strategy to cure a viral disease without harming the patient.

Select all that apply.

Find a process required for viral multiplication that is not needed for host cell survival and block that process.

Take a broad spectrum antibiotic in combination with an antiviral agent.

Use of immunosuppressive drugs to the affected organ.

Find a virus-specific molecule or enzyme not found in the host and target that molecule.

Suppose an enzyme has Km = 0.1mM and kcat = 10^3 s-1, and you perform an experiment in which [E]tot = 10-7M. Suppose that adding 0.1 µM of an inhibitor results in a Kmeff= 0.5 mM, and has no effect on kcat. Determine the substrate concentation that would be necessary to achieve a reaction velocity v of 5*10^-5Ms-1
