HIV Risk and the Freedom to Act Without Thinking: Alcohol Use and Sexual Behavior Among Adolescents on Probation

Through in-depth phenomenological interviews, 18 adolescents currently on probation describe how they make decisions about using alcohol and engaging in sexual behaviors. Two main threads emerge: they value spontaneity in sex and believe that they act spontaneously in regard to both sex and alcohol. At the same time, they describe being highly influenced by parents and peers. The researchers discuss the potential implications of these and other findings for HIV prevention and intervention.     

ISKCON AND IMMIGRANTS: The Rise, Decline, and Rise Again of a New Religious Movement

This article examines the impact of Indian immigration on the International Society for Krishna Consciousness (ISKCON), popularly known as "Hare Krishnas." After its emergence and initial growth as a new religious movement in the 1960s, ISKCON entered a period of decline and withdrawal in the 1980s because of second-generation problems and a series of financial and sexual scandals. A case study of the Chicago ISKCON temple shows that, since then, Indian immigration has provided ISKCON with new resources and a new target population for conversion. This has led to the reemergence of ISKCON as a religious movement, but one that differs in both its membership and its actions from the "seeker" movement of the 1960s and 1970s. The resurgence of ISKCON's movement activities is a product of congregational-level transnational interactions. The emergence of new religious movements, thus, must be seen in the context of broader historical dynamics as well as local microcosmic interactions. To the extent that these interactions are transnational in character, we should expect new religious movements to have an impact on the global "religious economy" with more rapid diffusion of religious innovations.     

Therapists’ Assessment and Treatment of Internet Infidelity Cases

In this study, we investigated through an Internet survey of 508 practicing marriage and family therapists which treatment decisions varied by gender of the client and background variables of therapists. The subjects responded to several typical Internet infidelity scenarios. We varied the gender of the person initiating the infidelity for half of one sample. We also asked the family therapy participants to respond to how they might assess and treat each presenting problem. They also evaluated problem severity, prognosis of the case, number of sessions necessary for treatment, and the extent to which a therapist would focus individually or relationally. Results indicate that there were differences in how therapists assessed and treated clients based on client gender, therapists’ age, therapists’ gender, how religious therapists reported they were, and the extent of therapists’ personal experience with infidelity.     

A test for multivariate structure

We present a test for detecting 'multivariate structure' in data sets. This procedure consists of transforming the data to remove the correlations, then discretizing the data and, finally, studying the cell counts in the resulting contingency table. A formal test can be performed using the usual chi-squared test statistic. We give the limiting distribution of the chi-squared statistic and also present simulation results to examine the accuracy of this limiting distribution in finite samples. Several examples show that our procedure can detect a variety of different types of structure. Our examples include data with clustering, digitized speech data, and residuals from a fitted time series model. The chi-squared statistic can also be used as a test for multivariate normality.     

A meta-analytic review of leadership impact research: Experimental and quasi-experimental studies

In this study we set out to conduct a comprehensive quantitative research analysis of literature reporting results on the causal impact of leadership by focusing on examining what we refer to as ‘leadership interventions.’ We defined leadership interventions as those studies where the researcher overtly manipulated leadership as the independent variable through training, assignment, scenario or other means. Our focus included both examining experimental and quasi-experimental as well as lab and field studies conducted in public and private organizations. Our goal was to address a simple question: do leadership interventions have the intended impact and if so to what degree? We conducted a comprehensive review of the published and unpublished literature and uncovered 200 lab and field studies that met our criterion as leadership intervention studies. We report here the findings of a series of meta-analyzed effects comparing the relative impact of leadership interventions across intervention types, leadership theories, and several common dependent variables. Overall, leadership interventions produced a 66% probability of achieving a positive outcome versus a 50–50 random effect for treatment participants, but this effect varied significantly when assessing moderators such as type of leadership theory.     

An analysis of pulsation periods of long period variable stars

Summary.  We report the results of a period change analysis of time series observations for 378 pulsating variable stars. The null hypothesis of no trend in expected periods is tested for each of the stars. The tests are non-parametric in that potential trends are estimated by local linear smoothers. Our testing methodology has some novel features. First, the null distribution of a test statistic is defined to be the distribution that results in repeated sampling from a population of stars. This distribution is estimated by means of a bootstrap algorithm that resamples from the collection of 378 stars. Bootstrapping in this way obviates the problem that the conditional sampling distribution of a statistic, given a particular star, may depend on unknown parameters of that star. Another novel feature of our test statistics is that one-sided cross-validation is used to choose the smoothing parameters of the local linear estimators on which they are based. It is shown that doing so results in tests that are tremendously more powerful than analogous tests that are based on the usual version of cross-validation. The positive false discovery rate method of Storey is used to account for the fact that we simultaneously test 378 hypotheses. We ultimately find that 56 of the 378 stars have changes in mean pulsation period that are significant when controlling the positive false discovery rate at the 5% level.     

Using social theory to leap over historical contingencies: A comment on Robinson

Conclusion To be fair to Robinson, it is worth mentioning that he does offer a number of qualifications to his thesis. He tries to avoid excessive determinism and at one point suggests: A satisfactory account should not imply an evolutionary notion and should leave open the possibility of historic discontinuities and of contingencies that generate alternative pathways of development, including alternative futures. In other words, maybe this embryonic TNS will never progress beyond its current stage or perhaps it will continue to grow but it will never become a real state. But the main thrust of Robinson’s account is strongly deterministic. In fact, he does not consider a single factor that might impede the unity of the global bourgoisie or derail transnational state formation. In a sense, Robinson’s mistake is that he has tried to derive a theoretical solution to a concrete problem that global capitalism has not yet solved in practice. While it might well be a logical step for capitalist elites to create a Transnational State, it is always risky to attribute too much rationality to an order that is notorious for its contradictions.     

Relationship between job control, work pressure and strain: studies in the USA and in The Netherlands

The purpose of this study was to test a model of job control, work pressure and strain in two samples in the USA and in The Netherlands. According to the proposed model, work pressure has a mediating role between job control and worker strain. The present model specifies three types of job control: task or instrumental control, conceptual or resource control, and decision organization control. Task and resource control are assumed to reduce the stressor of work pressure which, in turn, is related to high strain. Organization control is assumed to be positively related to work pressure. The model was tested in two samples : one US sample of 273office employees and one Dutch sample of 958 employees in a variety of jobs. The same measure of job control was used in both samples. Resultspartially confirm the proposed model. As predicted by the proposed model, high task control was related to low work pressure, whereas high organization control was related to high work pressure. The effects of task control and organization control on strain were mediated by work pressure for the measure of anxiety in the US sample and for the measure of stress in the Dutch sample. However, the mediating effect of work pressure was not found for job satisfaction in both samples, for the measure of mood disturbances in the US sample and for the measure of sick days in the Dutch sample. The proposed model is only partially confirmed by the results. These results confirm the importance of differentiating between different dimensions of job control.
