Adherence to antiretroviral medications in HIV: differences in data collected via self-report and electronic monitoring.

Controversy remains regarding the reliability of methods used to determine adherence to antiretroviral medication in HIV. In this study the authors compared adherence rates of 119 HIV-positive participants during a 6-month study, as estimated via electronic monitoring (EM) and self-report (SR). Adherence for both short (4-day) and long (4-week, or intervisit) periods was examined, as well as factors that underlie discrepancies between EM and SR. Results showed that intervisit EM estimates were consistently lower than those of SR. SR estimates based on shorter periods (4 days) were closer to those of EM. Higher discrepancies between EM and SR estimates were associated with lower cognitive functioning and externalized locus of control. These findings lend support for using both EM and SR methods; however, study design (e.g., length) and other factors (e.g., cognitive status, cost) should be considered.     

Evidence for the thalamic targets of the medial hypothalamic defensive system mediating emotional memory to predatory threats

Previous studies from our laboratory have documented that the medial hypothalamic defensive system is critically involved in processing actual and contextual predatory threats, and that the dorsal premammillary nucleus (PMd) represents the hypothalamic site most responsive to predatory threats. Anatomical findings suggest that the PMd is in a position to modulate memory processing through a projecting branch to specific thalamic nuclei, i.e., the nucleus reuniens (RE) and the ventral part of the anteromedial nucleus (AMv). In the present study, we investigated the role of these thalamic targets in both unconditioned (i.e., fear responses to predatory threat) and conditioned (i.e., contextual responses to predator-related cues) defensive behaviors. During cat exposure, all experimental groups exhibited intense defensive responses with the animals spending most of the time in the home cage displaying freezing behavior. However, during exposure to the environment previously associated with a cat, the animals with combined RE + AMv lesions, and to a lesser degree, animals with single AMv unilateral lesions, but not animals with single RE lesions, presented a reduction of contextual conditioned defensive responses. Overall, the present results provide clear evidence suggesting that the PMd’s main thalamic targets (i.e., the nucleus reuniens and the AMv) seem to be critically involved in the emotional memory processing related to predator cues.     

The Epistemology of the Book of Revelation

Recent developments in Christian philosophy, in particular epistemology, need to be enriched by a study of epistemology in the Bible. This article uncovers the epistemological assumptions of the Book of Revelation (specifically related to spiritual experience, revelation, and eschatological vindication) and points out how they may advance the development of a contemporary Christian epistemology.     

Defining Work Stress in Young People

Stress experienced by young workers can be very different from stress experienced by adults because of differing psychosocial developments. It is important to understand how early workplace experiences shape young workers' subsequent attitudes and behaviors, which may affect their psychological well‐being. This study examined how 18 young workers ages 17–29 perceive work stress. The authors found that young workers view job stress in 3 dimensions: lack of opportunity to learn, poor social interaction, and lack of opportunity to exercise initiative. Young workers also view work demands as challenging tasks and become job crafters to find more satisfaction in routine tasks.     

Self-control,parental crime,and discipline across three generations

The objective of this study is to examine the relationships between self-control, parental crime, and use of discipline across three generations. Data spanning 30 years from the National Longitudinal Survey of Youth, are analyzed using Structural Equation Modeling. This study focuses on whether different types of discipline used by parents predict the self-control of each successive generation. We also examine whether self-control and criminal activities of parents are predictive of parenting and resulting self-control of children. We find that discipline has a weak relationship to self-control but that parental crime and self-control do relate to the self-control of later generations.     

Role stress reexamined: An investigation of role stress predictors

R. L. Kahn, R. P. Wolfe, R. P. Quinn, J. D. Snock, and R. A. Rosenthal (1964, Organizational Stress: Studies in Role Conflict and Ambiguity, New York: Wiley) distinguished three different types of predictor of role stress; personal, interpersonal, and organizational. Based on a sample of young professional engineers this investigation studied the relationship betwen these three types of predictor and four forms of role stress (role conflict, role ambiguity, quantitative role overload, qualitative role underload). The relationship was studied both within each predictor set and between each predictor set. Employing bivariate and multiple regression analyses, variables were identified within each predictor set which were significantly predictive of role stress. In addition, comparison was made between the sets of predictor variables selected and between each of the four role stresses that were studied. The results support the relevance of personal, interpersonal, and organizational predictors to role stress, as well as suggesting that role stress researchers should pay more attention to differentiating between varying forms of role Stress.     

Gender,leadership style,and subordinate satisfaction: An experiment

As women continue to enter and advance within management ranks, how gender and leadership style influence subordinate satisfaction remains a significant issue. This paper reports on an experiment that analyzed the effects of gender and leadership style on subordinate satisfaction. While subjects were more satisfied in democratically led groups, gender of leader did not significantly affect satisfaction. Female subordinates were more dissatisfied than males in autocratically led groups.
