This paper employs mathematical models to examine the epidemic of AIDS among gay men. The approach allows consideration of arbitrary probability distributions for risky sex rates, the duration of sex lives, and the incubation time of AIDS following HIV infection, thus quite general models can be constructed. The analysis suggests what must happen for the epidemic to subside barring a cure by generalizing known formulas for the reproductive rate of HIV infection. This result shows that the simplifying assumption of exponential sex lives found in most other AIDS models is pessimistic relative to more realistic sex life distributions.

Sexual behavior is activated by motivation. An overwhelming majority of experimental studies of the intricacies of sexual motivation has been performed in rodents, most of them in rats. Sometimes it is desirable to generalize results obtained in this species to other species, particularly the human. It is hoped that studies of the neurobiology of rodent sexual behavior may shed light on the central nervous mechanisms operating in the human, and the search for efficient pharmacological treatments of human sexual dysfunctions relies partly on studies performed in rodents. Then the issue of generalizability of the rodent data to the human becomes crucial. We emphasize the importance of distinguishing between copulatory acts, behavior involving the genitals, and the preceding event, the establishment of physical contact with a potential mate. Comparisons between the structure of copulatory behavior in rats and humans show abysmal differences, but there may be some similarity in the underlying mechanisms.
Sex and power in the academy: modeling sexual harassment in the lives of college women
Social learning theory was used to examine the effects of a model's sexual imagery on the observer's sexual imagery. In the guise of a creative writing experiment, male and female college students were asked to listen to a tape recording of a same- or opposite-sex model relating a story in response to a sample TAT card. The story described a man and a woman in a physical sex encounter high sex , a romantic date medium sex , or a casual study date low sex. The sample TAT picture and model's story were omitted in the control groups. All subjects wrote stories in response to two other TAT cards.
The authors build an integrated model of the process by which academic sexual harassment undermines women's well-being; also examined is harasser power as a potential moderator of this process. Data from 1, college women suggest that sexual harassment experiences are associated with increased psychological distress, which then relates to lower academic satisfaction, greater physical illness, and greater disordered eating. The cumulative effect is greater disengagement from the academic environment, which in turn relates to performance decline i.
