Objective: There are no published placebo-controlled studies of any agent in the treatment of acute mania in children or adolescents. This is the first placebo-controlled study of lithium's efficacy in the treatment of acute mania in adolescents. Method: In this discontinuation study, participants received open treatment with lithium at…

The APA Task Force on Statistical Inference recently recommended reporting effect sizes alongside results of statistical significance tests. The purpose of this article is to investigate effect size usage in gifted education research and to follow up on a similar investigation published by Plucker (1997). A content analysis of effect size…

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…

This dissertation is a study of factors that contribute to dropout from distance learning classes in the Kentucky Community and Technical College System (KCTCS). It is divided into five chapters. Chapter One gives a history of distance learning through in KCTCS. It includes the background of the study, statement of the problem, purpose of the…

This paper examines the estimation of two-stage clustered RCT designs in education research using the Neyman causal inference framework that underlies experiments. The key distinction between the considered causal models is whether potential treatment and control group outcomes are considered to be fixed for the study population (the…

A journal club is defined as a group of individuals who meet regularly to discuss current trends in literature and have been advocated to bridge the gap of research and practice. With the popularity of the Internet, there are a variety of tools available for online learning through journal clubs including asynchronous discussions, which the…

This paper discusses how a seldom-used statistical procedure, recursive regression (RR), can numerically and graphically illustrate data-driven nonlinear relationships and interaction of variables. This routine falls into the family of exploratory techniques, yet a few interesting features make it a valuable compliment to factor analysis and…

The objective of this article is to compare male- and female-perpetrated sexual abuse in terms of victim and abuser characteristics, type of abuse, family structure, and worker information. Bivariate tests of significance were performed on the 1998 Canadian Incidence Study of Reported Child Abuse and Neglect, which included 308 male and 37 female…

The purpose of this study was to examine the relationship between instructor leadership type and teaching style in higher education classrooms. One survey, the Kaleidoscope Profile (Haggart, 1997) sought to determine instructor leadership type and an instructor's approach to teaching curriculum in the workplace. It was administered to two groups…

Researchers have long searched for a relationship between school resources and student achievement. The search for this relationship has relied heavily on the use of education production functions. Despite years of research on this topic, there has been little agreement concerning which resources are the most essential variables to increase…

This dissertation explored the relationships among three variables: meaning, moral reasoning, and diversity competencies. The relationships were examined to attempt explaining two central themes: professional citizenship and otherness leadership. A sampling of graduate students from business and education colleges at a Midwestern public…

The authors examined an association between mathematical content in college-level curricula and beginning salaries of graduating students on the basis of data collected from a public university in the southern region of the United States. The authors classified the mathematical content requirements of the curricula into the following 5 groups…

The sampling distribution is a common source of misuse and misunderstanding in the study of statistics. The sampling distribution, underlying distribution, and the Central Limit Theorem are all interconnected in defining and explaining the proper use of the sampling distribution of various statistics. The sampling distribution of a statistic is…

Considered in this paper are a mathematical discussion and an algorithm, and a computer program for Fisher's test. (Author)

Examines the question of how large a sample must be in order to produce empirical Bayes estimates which are preferable to other commonly used estimates, such as proportion correct observed score. (Author/RC)
