A Philosophic Inquiry Into Causation Comparing Diverse Metaphysical Systems, Jane Fisher

Masters Theses

Causation is a problem for philosophers because in explaining causation one must explain reality itself. Since the metaphysical systems of history are carefully reasoned claims concerning reality, they will be employed in this discussion of causation. We will examine the foundational posits of four metaphysical positions -- Buddhism, Platonism, Nominalism, and Realism -- and review the meaning each assigns for causation. We can then observe how the meaning of causation is altered depending on the system of metaphysics that serves as its context.

Attention Deficit Hyperactivity Disorder In Adolescents And Risk For Human Immunodeficiency Virus Infection, Margo A. Adams

Masters Theses

The adolescent population has been identified as the age group most quickly increasing in HIV transmission. Specific subpopulations of adolescents may be more at risk than others due to their unique situations. Characteristics commonly discussed in the literature describing individuals with attention deficits and hyperactivity disorders (ADHD) are similar to those that put individuals at risk for HIV infection (i.e., impulsivity, overactivity, drug use). This anonymous survey study investigated several hypotheses suggesting that ADHD adolescents may be more at risk than controls for HIV infection. Undergraduates at a midwestern university completed the sexual behavior survey. Eight male subjects reported a …
