To date most models of empowerment have focused on teachers' personal empowerment, which is defined as intrinsic task motivation reflecting an employee's orientation to his or her work role. Interestingly, little scholarly attention has been turned to the interaction of empowerment and work-team membership, that is, to empowerment acquired from…

Do students accurately perceive the sexual behavior of their peers? The results of this study indicate a dramatic difference between students' self-reported sexual behavior and their perceptions of peer sexual behavior. Specifically, students tend to overestimate the potentially risky sexual activity of their peers. The data also challenge popular…

As the initial phase of a longitudinal study of environmental perspective in college students, resident student opinion was sampled using the New Ecological Paradigm (NEP) scale administered through systematic alphabetical sampling. Sampling was also carried out by a blanket e-mail distribution of surveys for voluntary response. Results showed…

A survey of teachers and principals in Alberta was conducted to gain a descriptive profile of who is teaching physical education (PE) and to assess the relationship between PE specialists and variables associated with program delivery. A probability-sampling procedure was used to obtain a representative sample of schools. In these schools…

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…

This study examines the impact of passive and active parental consent procedures on the type of adolescents participating in a school-based survey examining substance use. Schools recruited from a random sample of metropolitan schools were assigned to passive or active parental consent condition. Results showed that participation rates in active…

More and more researchers, evaluators, and policy makers are recognizing that in order to best understand the factors precipitating, supporting, and prohibiting intimate violence against women, we must often gather information directly from battered women themselves. Such data collection, however, is not without its risks to the women involved in…

Purpose--The purpose of this paper is to investigate how a learning organisation can be created within the framework of the family SME in Ireland. Design/methodology/approach--No comprehensive list of independent family businesses in Ireland was available. To overcome this problem a pragmatic approach was taken in the construction of a sampling…

Analysis of continuous variables sometimes proceeds by selecting individuals on the basis of extreme scores of a sample distribution and submitting only those extreme scores to further analysis. This sampling method is known as the extreme groups approach (EGA). EGA is often used to achieve greater statistical power in subsequent hypothesis tests.…

Purpose: The goals of this review are to synthesize what is known about caregiving among diverse groups and to identify gaps in knowledge to guide future research on caregiving. The review focuses on conceptual and theoretical approaches, sampling strategies, measurement techniques, and similarities and differences found among groups and across…

Empirical studies addressing admission to and graduation from a doctoral program focusing on educational leadership are noticeably absent within the professional literature, and this study seeks to fill partially this void through testing specific hypotheses. Archival data were used to conduct a three group discriminant analyses where the…

Purpose: This article assesses the state of research on assisted living (AL) from 1989 to May 2004. Design and Methods: We undertook keyword searches for AL research and amplified these with searches of Web sites, conference proceedings, and follow-up inquiries. We annotated and coded the resultant items according to categories reflecting the…

Objective: To compare the dietary habits and nutritional status of mentally retarded (MR) and normal (NG) subjects and to examine the relationship between the dietary habits and nutritional status and the level of mental retardation in the MR group. Method: A case control design was utilized: 117 MR (random sampling) and 100 NG (quota sampling)…

Since the 1970s, researchers and public health and/or social policy communities have devoted increasing attention to family violence. Although officially reported crime figures for family violence appear to be declining, rates continue to be high in broadly defined racial and/or ethnic minority groups. More careful assessments of the potential…

A multitude of methods has been proposed to estimate the sampling variance of ratio estimates in complex samples (Wolter, 1985). Hansen and Tepping (1985) studied some of those variance estimators and found that a high coefficient of variation (CV) of the denominator of a ratio estimate is indicative of a biased estimate of the standard error of a…
