This study examined interrelationships among combat exposure, symptoms of posttraumatic stress disorder (PTSD), and family adjustment in a sample of male and female Operation Desert Storm veterans (N = 1,512). In structural equation models for both male and female veterans, higher combat exposure was associated with higher PTSD symptoms, which in…

This study investigated whether pre-task planning that embeds grammatical guidance to attend to a specific L2 form might be a suitable pedagogical choice in beginning-level foreign language classrooms. First-year high school students of English in Japan were asked to do an oral story-retelling task with a class partner under one of three…

In two studies, 10-year-olds from 2 German special schools as well as typically developing children of the same chronological age (CA controls) or the same mental age (MA controls) were compared on several aspects of working memory functions (i.e., size and input quality of the phonological store, speed and automatic activation of the subvocal…

The major purpose of this paper was to examine the quality of various aspects of higher education in the private sector of Pakistan by adopting a descriptive method of research. The population of the study constituted 270 administrators, 6,180 teachers and 61,108 students in existing 54 private universities and degree-awarding institutions of…

The research presented in this report examines the effect of prison-based postsecondary education (PSE) on offenders both while incarcerated and after release. Urban Institute researchers worked with the staff of four institutions in three states to conduct inmate focus groups and stakeholder interviews to explore the motivations for enrolling in…

The present study examined the concerns of teacher candidates in an early field experience. Thirty-five teacher candidates completed the Teacher Concerns Checklist (TCC, Fuller & Borich, 2000) at the beginning, middle and end of their early field experiences. Results showed that teacher candidates ranked impact as the highest concern, self as…

Controversy over the merits of Null Hypothesis Statistical Significance Testing (NHST) as a tool for advancing knowledge in the social sciences has intensified in recent years. Literature for and against the use of statistical significant tests is reviewed and three major limitations of these tests are summarized. The first is that "p"…

Procedures developed by Joreskog for studying similarities and differences in factor structures between different groups were applied to data from a study by Thurstoen to investigate the sampling stability of a hypothesized isolated configuration. The hypothesis of an isolated configuration was rejected but not by much. (Author/RC)

Focuses on the procedures available for substituting a special predictive coding method for some of the more complex general regression procedures. (Author)

The use of planned, or "a priori," and unplanned, or "post hoc," comparisons to isolate differences among means in analysis of variance research is discussed. Planned comparisons typically involve weighting data by sets of "contrasts." Planned comparison offer more power against Type II errors. In addition, they force…

In his early exposition of path analysis, Duncan (1966) noted that the method "provides a calculus for indirect effects." Despite the interest in indirect causal effects, most users treat them as if they are population parameters and do not test whether they are statistically significant. Sobel (1982) has recently derived the asymptotic…

Treats the problem of testing an ordered hypothesis based on the ranks of the data. Statistical procedures for the randomized block design with more than one observation per cell are derived. Multiple comparisions and estimation procedures are included. (Author/RC)
