This article examines the statistical determinants of risk preference. In a meta-analysis of animal risk preference (foraging birds and insects), the coefficient of variation (CV), a measure of risk per unit of return, predicts choices far better than outcome variance, the risk measure of normative models. In a meta-analysis of human risk…

The streamline is a basic position for competitive swimming starts mid turns and has been used in many studies on resistive forces. However, there is a wide yahweh, of theoretical interpretations in these studies, leading to diverse and questionable conclusions. The purpose of this study was to determine performance level differences in the…

Examined the findings of the "Teaching Children To Read" study of the National Reading Panel and the procedures of the study. Meta-analytic techniques found that the methodology and procedures were not adequate. Findings suggest that phonics, as an aspect of the complex reading process, should not be over-emphasized. (SLD)

The term "publication bias" usually refers to the tendency for a greater proportion of statistically significant positive results of experiments to be published and, conversely, a greater proportion of statistically significant negative or null results not to be published. It is widely accepted in the fields of healthcare and psychological…

Publication bias, sometimes known as the "file-drawer problem" or "funnel-plot asymmetry," is common in empirical research. The authors review the implications of publication bias for quantitative research synthesis (meta-analysis) and describe existing techniques for detecting and correcting it. A new approach is proposed that is suitable for…

This meta-analytic review combines the results of more than 60 studies to help determine the relative effects of work, nonwork, and demographic and individual factors on work interference with family (WIF) and family interference with work (FIW). As expected, work factors related more strongly to WIF, and some nonwork factors were more strongly…

There are a number of challenges facing those who set out to conduct systematic reviews of intervention effects in the social sciences. These challenges include formulation of a review problem, gathering data about relevant studies and outcomes, analyzing that data, and interpreting the results. The first challenge, formulating a workable review…

Comments on the article by J. S. Hyde (see record 2005-11115-001), in which Hyde provided an overview of the many meta-analyses that have compared men and women on psychological attributes. The current author argues that, despite the strengths of Hyde's study, a major problem with the analysis is its lack of a theoretical basis for considering sex…

The purpose of this article is to provide an alternative interpretation of the National Reading Panel's meta-analysis on phonics instruction. The NRP based its conclusion that phonics instruction was superior to other approaches on the interpretation of mean effect d statistics reported in its meta-analysis. In addition to looking at these d's, we…

The developing discourse which moves assessment away from a measurement model towards one of learner empowerment and the development of assessment for lifelong learning sets the context for this paper. Within this framework, we explore how the demands made on practitioners may influence current reported assessment practices. The reasons given by…

Language learners have unprecedented opportunities for developing second language literacy skills and intercultural understanding by reading authentic texts on the Internet and in multimedia computer-assisted language learning environments. This article presents findings from a meta-analysis of 11 studies of computer-mediated glosses in second…

Purpose: The purpose of this paper is to examine knowledge of strategy within the field of educational administration. It is intended to be the basis for future empirical research and inquiry into strategy in education by suggesting alternate ways of defining and researching strategy. Design/methodology/approach: The study examines the…

The far-reaching effects of literacy achievement have heightened the interest of educators and non-educators alike in the teaching of reading. Successful efforts to improve reading achievement emphasise identification and implementation of evidence-based practices that promote high rates of achievement. Behind the concept of evidence-based…

In order to fully evaluate the quality of evidence for any educational innovation, research is needed regarding consistency with theory, demonstrated effectiveness, and consistent implementation. The Help One Student to Succeed (HOSTS) Language Arts program was specifically mentioned in the "No Child Left Behind" act as a program that…

Background: Active Support (AS) is an approach for promoting increased engagement in activities by people with intellectual disability (ID). Method: We critically reviewed the available research on AS, and added a commentary to help guide future research and practice. Results: Despite weaknesses in the research design of some studies, there is…
