Abstract: There are a number of quantitative integrations on the effectiveness of sexual offender treatment. Firstly, this paper summarizes the findings of existing research integrations and gives an overview of the consistencies and inconsistencies in the different analyses. Although most of the reviews concluded that treatment on average is successful, the size of the effects differs considerably. In addition, moderator analyses do converge on certain variables, but differ in their conclusions for others. Secondly, this paper deals with the basic differences between integrations and relate them to the outcomes of individual research summaries (e.g., types of studies considered, method of quantitative integration, and the kind of moderator variables used for detailed analyses). The effects of differing meta-analytical decisions and strategies are demonstrated using a study pool that intended to merge and update those of existing integrations (Lösel & Schmucker, 2005). Furthermore, based on this study pool, a more detailed moderator analysis is presented to illustrate the importance of and the obstacles in the detailed appraisal of moderating factors.

Abstract: Research on the effect of suicide stories in the media on suicide in the real world has been marked by much debate and inconsistent findings. Recent narrative reviews have suggested that research based on nonfictional models is more apt to uncover imitative effects than research based on fictional models. However, there is substantial variation in media effects within the research restricted to nonfictional accounts of suicide. The present analysis provides some explanations of the variation in findings in the work on nonfictional media. Logistic regression techniques applied to 419 findings from 55 studies determined that: (1) studies measuring the presence of either an entertainment or political celebrity were 5.27 times more likely to find a copycat effect, (2) studies focusing on stories that stressed negative definitions of suicide were 99 percent- less likely to report a copycat effect, (3) research based on television stories (which receive less coverage than print stories) were 79 percent- less likely to find a copycat effect, and (4) studies focusing on female suicide were 4.89 times more likely to report a copycat effect than other studies. The full logistic regression model correctly classified 77.3 percent- of the findings from the 55 studies. Methodological differences among studies are associated with discrepancies in their results.

Abstract: Because estimates of effects sizes are often either misreported or not reported at all, meta-analysts must use conversion formulas that allow them to estimate effect sizes from the information available in a research report. The focus of this article is on formulas that convert F in ANOVA to eta squared, d, or the correlation coefficient. This paper demonstrates that the traditional F to r formula can differentially, and in some cases radically, inflate estimates of effect size when combining the results from studies with varying numbers of factors. Specifically, commonly used conversion formulas for converting F values to r, actually yield a partial r statistic that can be substantially larger than the desired zero-order r depending upon the number and relevance of additional factors in ANOVA. An alternative method to calculate non-partialled effect sizes according to the common formula (SSeffect/SStotal) is provided.

Abstract: Mediation is a common and effective third-party form of conflict resolution. This meta-analysis examines the satisfaction levels participants in mediation compared with those using an adversarial method of dispute resolution. Eleven articles were coded by the authors in order to discern overall satisfaction experienced by people who participated in mediation during child custody hearings, divorces, and other conflicts. The results from this meta-analysis indicate that overall satisfaction ratings were higher for mediation than for litigation. This study challenges existing literature in its findings that comparisons of satisfaction with mediation and adversarial methods of dispute resolution contrasted by gender, with men being more satisfied with mediation and women being more satisfied with adversarial methods.

Abstract: The amounts of leadership studies are voluminous. From major bookstores to airport kiosks and bookstands, the most recent titles in leadership are marketed as the new and the hottest bestsellers. Waves after waves of books and articles drench the leadership literature landscape. Readers, and writers, seem to never get enough of analyzing and seeking to understand this enticing, yet elusive, concept – leadership.

Recent interest, however, seems to center on the idea of paradoxes, contradictions, and dialectics at leadership level in organizations (Fairhurst, 2000; Barge, 1996). Often leaders are faced with radically opposing alternatives that, sometimes, both seem to be reasonable and necessary. These types of situations are fraught with tensions and dilemmas for the leaders.

In my research I seek to unpack the complexities that leaders are faced with in these types of choice situations between diametrically opposed options (i.e. trust-distrust, competition-cooperation, rational-emotional, dependence-independence, and change-stability). I believe that a dialectics theoretical approach holds much promise for scholars and practitioners in elucidating the way leaders manage tensions in organizational settings in order to benefit the respective organizations and reach its goals. In this essay, to be specific, I look at how charismatic and transformational leaders deal with tensions, contradictions, and dualities at a leader-follower level.
