The Role of the Black Church in HIV Prevention: Exploring Barriers and Best Practices

Black people have the highest rate of HIV/AIDS infection in the USA, and they are less likely to access quality physical and mental healthcare. To address these disparities as outlined in the National HIV/AIDS Strategy, there is a need for culturally congruent, innovative approaches to HIV/AIDS prevention. The first multi‐denominational national study of Black faith leaders was conducted utilizing focus groups that were held in 11 US cities. The 265 participants were faith leaders who reported involvement in such prevention practices as sponsoring HIV/AIDS workshops, integrating HIV/AIDS messaging in the worship service, hosting HIV/AIDS screenings, distributing written materials about HIV/AIDS through the bulletin or flyers, pastoral counselling, advocating for policies that provide quality healthcare to the community and disseminating HIV/AIDS prevention messages through new media such as the Church website. These findings, including attention to barriers to engagement, provide insight into innovative practices that can be integrated into faith‐based HIV/AIDS prevention programming.

How crucial is the response format for the testing effect?

Combining study and test trials during learning is more beneficial for long-term retention than repeated study without testing (i.e., the testing effect). Less is known about the relative efficacy of different response formats during testing. We tested the hypothesis that overt testing (typing responses on a keyboard) during a practice phase benefits later memory more than covert testing (only pressing a button to indicate successful retrieval). In Experiment 1, three groups learned 40 word pairs either by repeatedly studying them, by studying and overtly testing them, or by studying and covertly testing them. In Experiment 2, only the two testing conditions were manipulated in a within-subjects design. In both experiments, participants received cued recall tests after a short (~19 min) and a long (1 week) retention interval. In Experiment 1, all groups performed equally well at the short retention interval. The overt testing group reliably outperformed the repeated study group after 1 week, whereas the covert testing group performed insignificantly different from both these groups. Hence, the testing effect was demonstrated for overt, but failed to show for covert testing. In Experiment 2, overtly tested items were better and more quickly retrieved than those covertly tested. Further, this does not seem to be due to any differences in retrieval effort during learning. To conclude, overt testing was more beneficial for later retention than covert testing, but the effect size was small. Possible explanations are discussed.     

High Thrill and Adventure Seeking Is Associated with Reduced Interoceptive Sensitivity: Evidence for an Altered Sex‐specific Homeostatic Processing in High‐sensation Seekers

The personality trait of sensation seeking (SS) has been traditionally linked to the construct of exteroception, that is, sensing of the outside world. Little is known about the relationship between SS and interoception, that is, sensing originating in the body. Interoceptive sensations have strong affective and motivational components that may influence behaviours such as risk taking in SS. This investigation examined whether interoceptive differences contribute to different behavioural characteristics in SS. Using an inspiratory resistive load breathing task, the response to an aversive interoceptive stimulus as a basic homeostatic process was studied in 112 subjects (n = 74 women and 38 men). A linear mixed‐model approach was used to examine the influence of thrill and adventure seeking (TAS) on the interoceptive response across three levels of breathing resistances (10, 20, and 40 cm H₂O/L/second). High‐TAS relative to low‐TAS individuals were less responsive in evaluating intensities of perceived choking with increasing inspiratory resistive loads. This effect was driven by male, but not female, high‐TAS individuals and was particularly associated with reduced interoceptive sensitivity in men. The conceptualization of SS as primarily driven by exteroceptive stimuli can be expanded to a view of an altered homeostasis in SS, specifically in men.

The Role of Subsidies in Coordination Games with Interconnected Risk

Can subsidies promote Pareto‐optimum coordination? We found that partially subsidizing the cooperative actions for two out of six players in a laboratory coordination game usually produced better coordination and higher total social welfare with both deterministic and stochastic payoffs. Not only were the subsidized players more likely to cooperate (choose the Pareto‐optimum action), but the unsubsidized players increased their expectations on how likely others would cooperate, and they cooperated more frequently themselves. After removal of the subsidy, high levels of coordination continued in most groups with stochastic payoffs but declined in deterministic ones. This carry‐over disparity between the deterministic and stochastic settings was consistent with the economic theories that agents were more likely to keep the status quo option under uncertainty than without uncertainty. Hence, players with stochastic payoffs were more likely to keep the high coordination level (status quo) brought by the subsidy in the previous subsidy session. A post‐game survey also indicated that with stochastic payoffs, players focused on risk reduction. Temporary subsidies promoted lasting coordination because even after subsidy was removed, players still assumed that others players would prefer reduced risks from cooperation. With deterministic payoffs, however, the subsidy might crowd out other rationales for coordination, with many players indicating that the subsidy was the only reason for anyone to cooperate. Hence, the coordination level dropped when the subsidy was removed. Copyright © 2014 John Wiley & Sons, Ltd.     

Effect of a spiritual retreat on perceived stress of Nigerian Catholic immigrant sisters in the United States

Stress among immigrants may be due to loss of familiar environment and experience of discrimination. Spiritual retreats may be one way to manage stressful life situations. The present study examined whether participation in a six-day spiritual retreat results in changes in perceived stress and whether changes in perceived stress depend on participant’s demographic characteristics. A total of 88 Nigerian Catholic immigrant sisters completed the Perceived Stress questionnaire pre-retreat, day three, and immediately after a spiritual retreat. Friedman Two-way ANOVA by rank was used to determine if there are mean changes in perceived stress over the three-time period, while Kruskal–Wallis ANOVA was used to determine if there were demographic differences in perceived stress. There were no differences in perceived stress at baseline, but there was a significant reduction in perceived stress at Time 2 and 3. There were no differences in perceived stress for the demographic variables except age.     

Stability of complement and substitute relationships in time usage among discretionary activities

This research evaluates the stability of time usage relationships among discretionary activities. Traditional economists view products or services as substitutes if both can satisfy the same need of the consumer; they are complements if they are consumed jointly in order to satisfy some particular need. Complementary activities are grouped together in activity sets defined on an a priori basis. Several research questions are developed to investigate the following issues: (a) the stability over time of overall relationships between activities, in terms of visual representation using multidimensional scaling maps, and (b) the validity and stability of a priori classification of activities in activity sets. The results from multidimensional scaling maps are validated using structural equation modeling. The results suggest that time usage relationships are temporally stable. The broad needs of respondents, as represented by interrelationships between activities in sets, were found to be stable. We present reasons for believing that the conclusions of stability are comprehensive and can be used in the real‐world.     

Do procedures really matter when rewards are more important? A Pakistani perspective on the effects of distributive and procedural justice on employee behaviors

Introduction

Researchers agree that procedural justice and distributive justice interact so that high procedural fairness reduces the negative consequences of distributive unfairness.

Religiousness,collectivism, and helping behavior: The invigorating role of abusive supervision

IntroductionVoluntary helping behaviors are important for spurring organizational effectiveness.ObjectivesThis study investigates how employees’ religiousness and collectivism might enhance their propensity to help their peers on a voluntary basis, as well as how this relationship might be invigorated by the presence of abusive supervision.MethodsSurvey data were collected from employees and their supervisors in Pakistan-based organizations. The hypotheses were tested with hierarchical regression analysis.ResultsReligiousness relates positively to helping behavior, and this relationship is stronger when employees experience abusive supervision, possibly because their religiousness motivates them to protect their colleagues against the hardships created by such a resource-draining leadership style. Although collectivism does not have a direct significant relationship with helping behavior overall, abusive supervision invigorates this relationship.ConclusionFor organizations seeking to increase voluntary work behaviors, the results show that religiousness and collectivism are two personal resources that can enhance an organizational culture that promotes collegiality and mutual support, particularly when employees believe that their supervisors are hostile to followers and abuse their leadership positions.     

The Ehrenfest Fleas: From Model to Theory

A generalization of Ehrenfest's urn model is suggested. This will allow usto treat a wide class of stochastic processes describing the changes ofmicroscopic objects. These processes are homogeneous Markov chains. Thegeneralization proposed is presented as an abstract conditional (relative)probability theory. The probability axioms of such a theory and some simpleadditional conditions, yield both transition probabilities and equilibriumdistributions. The resulting theory interpreted in terms of particles andsingle-particle states, leads to the usual formulae of quantum and classicalstatistical mechanics; in terms of chromosomes and allelic types, it allowsthe deduction of many genetical models including the Ewens sampling formula;in terms of agents' strategies, it gives a justification of the ``herdbehaviour' typical of a population of heterogeneous economic agents.
