基于元分析的魅力型领导与组织绩效的关系研究

在对包含12 933个样本量的53篇有效文献进行元分析的基础上,分别对营利性组织和非营利性组织中魅力型领导与个体绩效、团队绩效、组织绩效的关系研究进行定量分析。研究结果表明,魅力型领导与各层面的绩效水平均显著正相关,其中与组织绩效的相关性最高,团队绩效次之,个体绩效最低;魅力型领导的测量方法、区域文化等对魅力型领导和员工绩效之间的关系起到调节作用。此外,对魅力型领导今后的研究进行了展望。     

A meta-analysis of the pique technique of compliance

A random-effects meta-analysis was undertaken to examine the effectiveness of the pique technique of compliance-gaining. Results indicated an overall significant effect of the pique technique on increased compliance rate across 17 comparisons (r = .27). Moderator analyses showed the technique worked significantly better than controls in gaining compliance when a smaller amount was requested, when the reason for the request was included, and when the technique was used in France. In addition, the pique technique was more successful than control requests in terms of the total amount of money or time given by participants and the percentage of participants inquiring about the requests. Theoretical and practical implications for the success of pique technique are discussed for future research.     

Effects of attributed responsibility and response strategies on organizational reputation: A meta-analysis of situational crisis communication theory research

Scholars utilizing situational crisis communication theory (SCCT) mainly examine how attributed responsibility affects organizational reputation and how response strategies matched with the amount of attributed responsibility protect reputation. The findings on these 2 important questions have been mixed. A meta-analysis of 35 investigations from 24 studies published between January 1990 and March 2015 was conducted to explain the mixed findings and reveal average correlations. Attributed responsibility was strongly associated with reputation at –.54, and response strategies were only weakly associated with reputation at .23. Equally important, crisis vignette choice moderated the responsibility-reputation association. Crisis clusters, reputation measurements, sample choice, and crisis vignette choice moderated the match-reputation association. Theoretical, methodological, and practical implications were discussed.     

TP与GP化疗方案对肺癌患者骨髓抑制影响的Meta分析

目的通过Meta分析对紫杉醇+顺铂(TP)与吉西他滨+顺铂(GP)化疗方案对肺癌抗肿瘤药物治疗患者骨髓抑制的影响进行系统分析,探讨TP和GP的骨髓抑制差别。方法通过荟萃分析对TP与GP的骨髓抑制研究进行同质性检验和合并效应量的估计。结果同质性检验:χ2=91.84,自由度为29,P0.00001;合并效应量的估计:OR合并=1.36,OR合并95%可信限为0.90~2.04。OR合并的检验Z=1.482.41,P=0.14。结论 TP与GP化疗时对患者的骨髓抑制不良反应情况没有本质区别。     

Emotion Knowledge, Social Competence, and Behavior Problems in Childhood and Adolescence: A Meta-analytic Review

The present meta-analytic review examined the magnitude of the relation between discrete emotion knowledge and three of its most commonly studied correlates in childhood and adolescence: social competence, internalizing problems, and externalizing problems. Emotion knowledge demonstrated small to medium-sized relations with each correlate. Moderators of effect size were also examined and included multiple sample and methodological characteristics. Using random effects models, significant moderators of effect size for relations between emotion knowledge and externalizing problems included sample recruitment, sample age, and the source of externalizing problems ratings. Moderators of effect size were not found for emotion knowledge and social competence, and the effect sizes across samples for emotion knowledge and internalizing problems were homogeneous. Results highlight the relatively consistent yet modest relations between emotion knowledge and its correlates. Implications for applied research and new directions for research on emotion knowledge using innovative methods are discussed.     

Workplace resources to improve both employee well-being and performance: A systematic review and meta-analysis

Organisations are becoming increasingly aware of the importance of employees in gaining and maintaining competitive advantage. The happy worker–productive worker thesis suggests that workers who experience high levels of well-being also perform well and vice versa; however, organisations need to know how to ensure such happy and productive workers. The present review and meta-analysis identifies workplace resources at the individual, the group, the leader, and the organisational levels that are related to both employee well-being and organisational performance. We examine which types of resources are most important in predicting both employee well-being and performance. We identified 84 quantitative studies published in print and online from 2003 to November 2015. Resources at either of the four levels were related to both employee well-being and performance. We found no significant differences in employee well-being and organisational performance between the four levels of workplace resources, suggesting that interventions may focus on any of these levels. Cross-sectional studies showed stronger relationships with well-being and performance than longitudinal studies. Studies using objective performance ratings provided weaker relationships between resources and performance than self-rated and leader/third-party-rated studies.     

The Impact of Parental Remarriage on Children

Abstract

A meta-analysis of 61 studies was undertaken to determine the impact of parental remarriage on the academic achievement and psychological well-being of children, of which the vast majority were adolescents. Separate analyses were done on studies that did and did not use sophisticated controls in their analyses. Comparisons were made between children from remarried versus intact families as well as children from remarried and divorced or widowed single-parent families. Children from remarried family structures achieved academic levels that were generally more than two-tenths of a standard deviation lower than children from intact families. Children from remarried families also achieved somewhat lower levels than children from corresponding single-parent family structures. The difference between children from remarried families and children from intact families was nearly two- tenths of a standard deviation for measures of psychological well-being, for studies that did not use sophisticated controls and was somewhat less for studies that did use sophisticated controls. The significance of these results is discussed, doi: 10.1300/J002v40n04_05     

Issues Related to Sports Gambling

This paper looks at various issues that are of interest to the sports gambler. First, an expression is obtained for the distribution of the final bankroll using fixed wagers with a specified initial bankroll. Second, fixed percentage wagers are considered where the Kelly method is extended to the case of simultaneous bets placed at various odds; a computational algorithm is presented to obtain the Kelly fractions. Finally, the paper considers the problem of determining whether a gambling system is profitable based on the historical results of bets placed at various odds.
