A study of undergraduate computer science students examined changes in major after the first year. The study examined the fates of 256 students who enrolled as first-year students in the same fall semester. The students were classified according to gender and their declared major at the beginning of the second year. The students studied were enrolled at a large Midwestern university several years ago. Discuss how you would conduct a similar study at a college or university of your choice today. Include a description of all variables that you would collect for your study.

Samuel has a private practice and he receives most of his income from clients covered by managed care companies. He is completing the paperwork to get both reimbursement and approval of the number of sessions for two new clients. Samuel is aware that the diagnosis he gives will affect the responses of the managed care reviewer. The first client, Charlie, has experienced a recent interpersonal loss and has some behaviors that meet the criteria for major depression. The second client, Amanda, has also experienced a recent interpersonal loss and has some behaviors that meet the criteria for a personality disorder. For Charlie, Samuel knows that if he gives a diagnosis of bereavement he will likely be told that the client does not need treatment and he will not be reimbursed, but if the client has Major Depressive Disorder, then the client may be given six or eight sessions. Similarly, if Samuel gives Amanda a diagnosis of Major Depressive Disorder, she will likely be approved for several sessions. However, if he assigns a diagnosis of a personality disorder, then she will not be approved for counseling. Samuel truly believes that both individuals could benefit from counseling with him.

Regarding the case study above, what diagnosis should Samuel give Charlie and Amanda? Why? Do you think it is unethical or illegal for Samuel to give Charlie or Amanda one diagnosis or another? Is it unethical that an insurance company, who has not yet met the client can determine whether they will have services paid for, or how many sessions they can have? Why/why not?

Bean beetles (Callosobruchus maculatus) are agricultural pest insects of Africa and Asia. Females lay their eggs on the surface of beans (Family Fabaceae). Eggs are deposited singly and several days after deposition, a beetle larva (maggot) burrows into the bean. At 30°C, pupation and emergence of an adult beetle occurs 21–30 days after an egg was deposited. Adults are mature 24–36 hours after emergence and they do not need to feed. Adults may live for 1–2 weeks, during which time mating and oviposition (laying of eggs) occurs. Since larvae cannot move from the bean on which an egg was deposited, the oviposition choice of a female determines the future food resources available to their offspring. As a result, it is the most critical choice a female makes for her offspring, because it will influence their growth, survival, and future reproduction. Although females can be induced to lay eggs on a wide range of bean species, very few bean species result in normal development and the successful emergence of adults.
