The three-contingency model of performance management (Malott, 1992, 1993, 1999) was used to analyze interventions in the "Journal of Organizational Behavior Management (JOBM)" from the years 1990 through 2005 (Volume 11[1]-Volume 25[4]). The current article extends previous reviews (Malott, Shimamune, & Malott, 1992; Otto & Malott, 2004) by…

Current comparative research literature, although abundant in scope, is inconclusive in its findings, as to the quality and effectiveness of distance education versus face-to-face methods of delivery. Educational research produces contradictory results due to differences among studies in treatments, settings, measurement instruments, and research…

The aging population is a worldwide challenge. Understanding how older adults have been portrayed would provide a foundation on which future scholarship can build. This study assesses and critiques the assumptions underlying the portrayal of older adults and their learning in adult education journals from 1980 to 2006. On reviewing 93 articles in…

The mathematical representation of E. Brunswik's (1952) lens model has been used extensively to study human judgment and provides a unique opportunity to conduct a meta-analysis of studies that covers roughly 5 decades. Specifically, the authors analyzed statistics of the "lens model equation" (L. R. Tucker, 1964) associated with 249 different…

In 2 studies, we investigated victim attributions (Study 1) and outcomes (Study 2) for workplace aggression and sexual harassment. Drawing on social categorization theory, we argue that victims of workplace aggression and sexual harassment may make different attributions about their mistreatment. In Study 1, we investigated victim attributions in…

For the thirty-eighth time, the Research and Theory Division of the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented at the annual AECT Convention in Indianapolis, Indiana. The Proceedings of AECT's Convention are published in two…

Most empirical tests of mediation utilize cross-sectional data despite the fact that mediation consists of causal processes that unfold over time. The authors considered the possibility that longitudinal mediation might occur under either of two different models of change: (a) an autoregressive model or (b) a random effects model. For both models,…

In the past two decades, numerous meta-analyses have been published that examine the question of psychotherapy equivalence. Hunsley and Di Giulio (2002) critically reviewed this literature and concluded that there was abundant evidence that the Dodo bird verdict of equivalence across psychotherapies is false. In this article, we summarize and…

Grief therapies with children are becoming increasingly popular in the mental health community. Nonetheless, questions persist about how well these treatments actually help with children's adjustment to the death of a loved one. This study used meta-analytic techniques to evaluate the general effectiveness of bereavement interventions with…

REL Appalachia conducted a systematic review of the research evidence on the effects of increased learning time. After screening more than 7,000 studies, REL Appalachia identified 30 that met the most rigorous standards for research. A review of those 30 studies found that increased learning time does not always produce positive results. However,…

This meta-synthesis is on research conducted by different researchers in a team research project on learners' experience of aggression in secondary schools in South Africa. The objective was to obtain a broader understanding of their experience of aggression in different contexts in South Africa, as well as possible ways to assist learners to…

Models of stress and health suggest that emotions mediate the effects of stress on health; yet meta-analytic reviews have not confirmed these relationships. Categorizations of emotions along broad dimensions such as valence (e.g., positive and negative affect) may obscure important information about the effects of specific emotions on physiology.…

The purpose of this review was to evaluate whether the Penn Resiliency Program (PRP), a group cognitive-behavioral intervention, is effective in targeting depressive symptoms in youths. We identified 17 controlled evaluations of PRP (N = 2,498) in which depressive symptoms had been measured via an online search of PsycInfo, Medline, ERIC, and…

The present meta-analysis examines the effect of grade retention on academic outcomes and investigates systemic sources of variability in effect sizes. Using multilevel modeling (MLM), the authors investigate characteristics of 207 effect sizes across 22 studies published between 1990 and 2007 at two levels: the study (between) and individual…

Second language (L2) reading comprehension is generally facilitated by both native language and L2 glosses. However, CALL learning opportunities are still not as common as they should be, and, therefore, the present meta-analysis contributes further evidence supporting the inclusion of more CALL experiences in reading contexts. The present study,…
