It is well-known that for normally distributed errors parametric tests are optimal statistically, but perhaps less well-known is that when normality does not hold, nonparametric tests frequently possess greater statistical power than parametric tests, while controlling Type I error rate. However, the use of nonparametric procedures has been…

Organizational religiosity is analyzed with data from a national survey of faith-based social service coalitions (N = 656). Twenty-one items related to religious practices within these organizations result in three distinct factors: service religiosity, staff religiosity and organizational religiosity scales. Self-defined faith-based coalitions…

This study examined the relationships between racial identity attitudes and religious orientation among African American college students. The participants were 270 African American college students from 2- and 4-year colleges in the Northeast. Multiple regression analyses were conducted and the results indicated that racial identity attitudes…

The effectiveness of the Tabu variable selection algorithm, to identify predictor variables related to a criterion variable, is compared with the stepwise variable selection method and the all possible regression approach. Considering results obtained from previous research, Tabu is more successful in identifying relevant variables than the…

This study addresses the utility of the resilient, overcontrolled, and undercontrolled personality prototypes for predicting children's and adolescents' problem behaviour in a longitudinal general population sample (N = 491). Both parents and one child participated in the study at two measurement occasions separated by a 3-year interval. The major…

This article describes a validity study conducted among middle school students comparing self-reported sun safety behaviors from a diary with readings from ultraviolet (UV) monitors worn on different body sites. The UV monitors are stickers with panels that turn increasingly darker shades of blue in the presence of increasing amounts of UV light.…

The difficulty in education to determine causality between means and ends brings various issues and variables to the discussion about the antecedents of school effectiveness. Although teachers' level of professional development is clearly among the factors influencing student outcomes, little is known about the extent to which teachers connect…

This study introduces three growth modeling techniques: latent growth modeling (LGM), hierarchical linear modeling (HLM), and longitudinal profile analysis via multidimensional scaling (LPAMS). It compares the multilevel growth parameter estimates and potential predictor effects obtained using LGM, HLM, and LPAMS. The purpose of this multilevel…

This study used quantitative measures to gather data from online students to analyze the effects of perceptions about teacher verbal immediacy and classroom community on students' level of satisfaction, perceived learning, and online discussion frequency. Using convenience sampling, 214 students were recruited from undergraduate and graduate…

The former HEW National Strategy for Youth Development Model was a community-based planning and procedural tool designed to enhance positive youth development and prevent delinquency through a process of youth needs assessment, development of targeted programs, and program impact evaluation. A series of 12 Impact Scales most directly reflect the…

The logit methodology provides a unique way of examining input-output relationships for social systems where the principal output of the analysis is a probability of some action or state. (Author)

General fund resource allocation and utilization in 27 academic departments at the University of California, Santa Barbara, during 1977-1984 were examined. A two-step research methodology was employed to provide a comprehensive analysis of possible budgetary determinants. The first step entailed a pooled multivariate regression analysis with eight…

The accuracy and variability of 4 cross-validation procedures and 18 formulas were compared concerning their ability to estimate the population multiple correlation and the validity of the sample regression equation in the population. The investigation included two types of regression, multiple and stepwise; three sample sizes, N = 30, 60, 120;…

The major purpose of this investigation is to identify the extent to which selected motivational, aptitude, interest, and attitudinal criteria predict academic success in social science courses for transfer and occupational-technical community college students. (Author)
