1. Surgery and Germs Joseph Lister (5 April 1827 - 10 February 1912 and for whom Listerine is named!) was a British physician who was interested in the role of bacteria in human infections. He suspected that germs were involved in transmitting infection, and so he tried using carbolic acid as an operating room disinfectant. In 75 amputations, he used carbolic acid 40 times. Of the 40 amputations using carbolic acid, 34 of the patients lived. In the 35 amputations without carbolic acid, 19 lived. The question of interest is whether carbolic acid is effective in increasing the chances of surviving an amputation. a. Is this an experiment or an observational study? b. Are the sample sizes large enough to use the normal approximation? c. Use Minitab, R or a calculator, estimate the difference in survival rates using a 95% confidence interval and interpret your interval in context. d. Do you have any concerns about the ethics of this study?

When scuba diving, it is important to come back to the surface of the water from deep dives slowly. If this does not happen, then the diver can get the “bends”. Using the information provided below, determine the moles of N₂ and O₂ dissolved in 7.5 L of blood at 298 K at a depth of 100.0 feet below the surface of the water and at the surface of the ocean. If the diver were to suddenly return to the surface, how many moles of N₂ and O₂ would “undissolve” from the blood (assume no loss of gas molecules from the system)? What volume would this amount of N₂ and O₂ occupy at the surface of the ocean? What would happen to a human if that volume of N₂ and O₂ were not expelled through the lungs? Based on your answers, explain why returning to the surface of the ocean after a deep dive is so important, and what the “bends” is. (Henry’s Law constants at 25°C K(O₂) = 4.40×10⁹ Pa, K(N₂) = 8.68×10⁹ Pa.)

1. Age-earnings profiles, especially those for men, tend to be very steep early on and then flatten out. According to the human-capital investment framework, this occurs because

   		on-the-job training investments have a higher payoff for younger workers.
   		on-the-job training investments that lead to the acquisition of general skill will be paid for by workers in the form of lower wages.
   		on-the-job training investments lead to new skills and subsequently higher wages
   		All of these.

1. A government policy likely to be helpful in dealing with structural unemployment is

   		a requirement that firms give employees advance notice of plant closings.
   		a minimum wage law.
   		an increase in unemployment insurance.
   		the creation of public sector jobs.

1. Employment contracts for the majority of American workers take the form of

   		formal documents precisely specifying in advance the obligations of each party
   		oral agreements that can be legally enforced when necessary.
   		a broad set of informal understandings between each party.
   		collective bargaining agreements made between an employer and a union.

Assume you are responsible for the management and administration of the two facilities listed above. You have to orient the newly appointed manager by providing an overview on managing long-term care. You also need to discuss the programs of the two facilities.

·      What are the various multidisciplinary departments (teams) included in your facilities? Listed Above

·      Who comprise the target population being served by the various programs provided by your chosen facilities?

·      What are the major staffing and human resource issues faced by your chosen facilities?

·      What are the significant trends in long-term care likely to impact the operation of the various programs provided by your chosen facilities, and what is your plan of action to overcome them?

·      What are the various forms of cooperation and integration existing in your chosen facilities? Discuss the nature of management, financing, and quality issues related to integration and cooperation in the facilities?

Whenever someone suggests that when families or guardians be financially compensated for agreeing to donate organs from a loved one (or someone in their care) who has just died, the following objection is made: If the formerly “free” organ now has a price placed upon it, then transplant operations will become more expensive. Is this an economically valid argument? Why or why not?

(The present system requires that organ donation be voluntary on behalf of individuals making donations, or the families who make the decision regarding a loved one who is about to die. Furthermore, the donation is made to a non-profit organ procurement organization, which then receives a fee when it directs the newly procured organ to the hospital where it will be used in the transplant operation.)

PLEASE KEEP IN MIND THAT THIS IS NOT A QUESTION ABOUT THE ETHICS OF SELLING HUMAN ORGANS. WE ARE DEALING WITH THE ECONOMIC ARGUMENT THAT OPPONENTS OF SUCH TRANSACTIONS HAVE BEEN MAKING. Furthermore, DO NOT ASSUME ANY ROLE OF INSURANCE OR GOVERNMENT PAYMENTS IN YOUR ANSWER.

Q1. Suppose you are a Development Economist working at the United Nations Development Program and you are provided with the following information:

The Human Development Report shows that the HDI of South Africa was 0.653 (and its rank was 121) and that of the Peru was 0.767 (and its rank was 82). South Africa’s per capita income (in PPP dollars) was 11,192 and that of Peru was 5,678.

Comment and explain how you will analyze these countries economic development strategies?

    Q2. Briefly explain what makes the Lewis model a “development” model rather than an “economic growth” model?

   Q3. During the past decade, India has invested about 22% of its GDP while China’s investment rate has been double that of India’s. India’s annual growth rate has been about 6% while that of China has been about 9%. What conclusions can you draw in terms of economic growth and development theories and models?
