This paper presents a conceptual, contingent model of management development. It explains the nature of the UK hospitality industry and its potential influence on MD practices, prior to exploring dimensions and relationships in the model. The embryonic model is presented as a model that can enhance our understanding of the complexities of the…

This report responds to the need for information on how to improve adolescent writing skills. The study builds upon previously published "Reading Next" results and highlights key elements essential to improving writing. The study used meta-analysis, allowing researchers to determine the strength and consistency of the effects of different…

Introduction: Physicians spend a considerable amount of time in Continuing Medical Education (CME) to maintain their medical licenses. CME evaluation studies vary greatly in evaluation methods, levels of evaluation, and length of follow-up. Standards for CME evaluation are needed to enable comparison among different studies and to detect factors…

Do adopted children show lower self-esteem than nonadopted peers, and do transracial adoptees show lower self-esteem than same-race adoptees? Adopted children are hypothesized to be at risk of low self-esteem. They may suffer from the consequences of neglect, abuse, and malnutrition in institutions before adoption. They have to cope with their…

Practitioners working in social welfare, education, judicial circuits, psychology, and many other domains of human sciences daily decide on best treatments for their clients. The authors expect those practitioners to base their decisions on evidence from scientific research. The Campbell collaboration is an international nonprofit organization…

This article examines what we know about effective adolescent writing instruction and what we still need to know. What we know is established by bringing together the findings from three sources: a comprehensive meta-analysis of experimental and quasi-experimental studies (Graham & Perin, 2007), a meta-analysis of single-subject design studies…

A review of studies published between 1980 and 2005 shows a significant positive effect of specialized training on the competency of caregivers in childcare (d=0.45, S.E.=0.10). Experimental results from the meta-analysis were significantly smaller for settings with no fixed curriculum content, delivery of the training at multiple sites and…

Person-centered education is a counseling-originated, educational psychology model, overripe for meta-analysis, that posits that positive teacher-student relationships are associated with optimal, holistic learning. It includes classical, humanistic education and today's constructivist learner-centered model. The author reviewed about 1,000…

Study Purpose: This article examines the influence of "Educational Administration Quarterly (EAQ)" on the scholarly literature in education during the 25-year period 1979 to 2003. This article continues part of the first critique of EAQ conducted by Roald Campbell in 1979. Study Methods: Two citation measures are used in this study to assess EAQ…

Numerous studies show that children's language ability is related to false-belief understanding. However, there is considerable variation in the size of the correlation reported. Using data from 104 studies (N=8,891), this meta-analysis determines the strength of the relation in children under age 7 and examines moderators that may account for the…

The purpose of this synthesis is to summarize the effectiveness of peer-mediated interventions on the mathematics performance of both students with disabilities and those at risk for mathematics disabilities. Meta-analytic techniques were used to calculate mean effect sizes for 17 studies that met inclusion criteria. Results indicate that…

S. Jackson and S. Jacobs' article entitled "Generalizing about Messages" represents an important methodological innovation in communication research. The article urges procedural change by recommending the use of multiple-message designs because of a weakness in single-message designs; it recommends analyzing message-replication data…

This work supplements a previous work, "Philosophical Aspects of Library Information Science in Retrospect." It explores Library Information Science, which deals with the facilitation of recorded knowledge, the metalibrarianship encompassing the theoretical aspects of a broad range of recorded communications, and the philosophies…

This paper summarizes the results of a quantitative review of the validity of the employment interview. It begins by discussing factors that make the interpretation of interview validity data difficult. The interpretation of interview validity data is shown to be hampered by the heterogeneity of constructs and measurement methods in the interview.…

One purpose for combining research studies is to estimate a population treatment effect. The internal validity of a model for how effect size estimates should be computed and combined will hinge upon the homogeneity of the effect size variation. Effect size variation may be assessed in the form of a summary fit statistic, and a direct…
