The aims of the research were to identify the environmental factors that relate to the work of regular school teachers who have students with special needs in their classroom, and to find out the correlation between these factors and teacher burnout. A total 330 primary school teachers filled in a questionnaire that had three parts: (1) personal…

The Pearson correlation is used to depict effect sizes in the context of item response theory. Amultidimensional Rasch model is used to directly estimate the correlation between latent traits. Monte Carlo simulations were conducted to investigate whether the population correlation could be accurately estimated and whether the bootstrap method…

Although concern is often expressed that frequent media exposure may adversely affect the self-esteem and racial self-esteem of African American youths, evidence to support this assumption has been limited. To examine this issue, the author collected data among 156 African American high school students, testing connections among racial…

This article describes an empirical investigation of whether performance on a senior-level assessment of methodological and statistical knowledge was related to elapsed time since students took prerequisite methods and statistics courses. In a senior-capstone course, 50 students completed a 50-item multiple-choice assessment measuring their…

A distinction is made between objective and subjective assessment when quality of life evaluation is considered. The aim was to explore the association between objective and subjective appraisals within similar quality of life domains. Correlations between scores on objective and subjective quality of life measures concerning choice, activity and…

Authoritative parenting has been associated with positive outcomes for children and adolescents, but less is known about the mechanisms responsible for such effects. Two longitudinal studies examined the hypothesis that the relation between authoritative parenting and adolescents' adjustment is mediated by adolescents' level of dispositional…

Recently, G. C. Van Orden, J. G. Holden, and M. T. Turvey (2003) proposed to abandon the conventional framework of cognitive psychology in favor of the framework of nonlinear dynamical systems theory. Van Orden et al. presented evidence that "purposive behavior originates in self-organized criticality" (p. 333). Here, the authors show that Van…

This study describes a method for incorporating external estimates of intraclass correlation to improve the precision for the analysis of an existing group-randomized trial. The authors use a random-effects meta-analytic approach to pool the information across studies, which takes into account any interstudy heterogeneity that may exist. This…

The purpose of this study was to examine musical performance anxiety in children, with a focus on potential gender differences. Twenty-six sixth-grade students performing in a piano recital were monitored continuously on measures of heart rate and behaviour. Participants were interviewed in the months prior to the recital and they completed the…

The author presents new evidence on the effects of attendance on academic performance. He used a large panel data set for introductory microeconomics students to explicitly take into account the effect of unobservable factors correlated with attendance, such as ability, effort, and motivation. He found that neither proxy variables nor instrumental…

We conducted three studies that investigated first through third grade children's ability to identify and remember deductive inference or guessing as the source of a belief, to detect and retain the certainty of a belief generated through inference or guessing and to evaluate another observer's inferences and guesses. Immediately following a…

Student drop-out is a complex phenomenon; this paper addresses some dysfunctional precursors, which may predispose college students to drop out of further education. These precursors are seen in the light of institutional failure to transmit appropriate, positive values to children in schools, in respect of vocational education and training. Two…

Background: This study examined the effects of age and two novel factors (intensity and emotion category) on healthy children's developing emotion-processing from 4 to 15 years using two matching paradigms. Methods: An explicit emotion-matching task was employed in which children matched the emotion of a target individual, and an implicit task…

Background: There is a growing interest in the study of the genetic origins of comorbidity, a direct consequence of the recent findings of genetic loci that are seemingly linked to more than one disorder. There are several potential causes for these shared regions of linkage, but one possibility is that these loci may harbor genes with manifold…

Background: This study sought the answer to three questions: 1. Is having an intimate partner associated with the level of delinquency? 2. Does the quality of the relationship with an intimate partner, operationalised as partner support, predict the level of delinquency? 3. Does a relationship with an intimate partner or age moderate the…
