The highest rates of sexually transmitted infections in the U.S. occur among adolescent females. One prevention strategy promoted for sexually active adolescents is condom use: therefore, influences on correct and consistent condom use are worth examining. Because interventions and observational research into predicting and increasing condom use have yielded mixed results, we hypothesized that a theoretically driven model incorporating female adolescents' perceptions about partner sentiments along with their own perceptions, intentions, and behaviours would improve condom use predictions. We also measured condom use errors and consistency for a more precise estimate of effective use than is common in the literature. In three structural equation models tested on a sample of 519 female adolescents, we found that intentions were associated with both correct and consistent condom use; that females' expectancy beliefs about condom use were associated with intentions; and that females' expectancy beliefs about partners' sentiments reduced the impact of their expectancy beliefs about condom use. The implications of these relations upon condom use correctness and consistency are discussed with respect to informing interventions, among other future research. 相似文献

Postpartum psychiatric changes can range from maternity blues to psychosis. Causality is still undetermined, but explanations for these disturbances often focus on hormonal changes and dysregulation. Researchers have begun the process of delineating what neurobiological factors may be associated with depressive disorders in pregnancy and the postpartum. This article reviews the current literature on the roles of gonadal and pituitary hormones in the psychopathophysiology of postpartum mood disorders. Other biological factors, such as biogenic amines, neuroactive steroids, cholesterol, and fatty acids, are also discussed. The potential benefits of neuroimaging to aid in understanding neuropsychiatric changes that occur in the context of postpartum depression are also considered. 相似文献

This paper considers an approach to teaching ethics in bioengineering based on the How People Learn (HPL) framework. Curricula
based on this framework have been effective in mathematics and science instruction from the kindergarten to the college levels.
This framework is well suited to teaching bioengineering ethics because it helps learners develop “adaptive expertise”. Adaptive
expertise refers to the ability to use knowledge and experience in a domain to learn in unanticipated situations. It differs
from routine expertise, which requires using knowledge appropriately to solve routine problems. Adaptive expertise is an important
educational objective for bioengineers because the regulations and knowledge base in the discipline are likely to change significantly
over the course of their careers. This study compares the performance of undergraduate bioengineering students who learned
about ethics for stem cell research using the HPL method of instruction to the performance of students who learned following
a standard lecture sequence. Both groups learned the factual material equally well, but the HPL group was more prepared to
act adaptively when presented with a novel situation. 相似文献
