Tests alternative theoretical models of environment-individual interaction. Findings point to the importance of person-environment fit in the areas of congregation, impulse control, and segregation in explaining morale. (Author)

This article demonstrates, through a case study, the use of pre-existing subgroups as moderator variables to increase the predictive effectiveness of educational research. Use of moderator variables in this study increased the amount of explained variance by 460 percent. (JDS)

A microcomputer program that computes statistical power for analyses performed by multiple regression/correlation is described. The program features a spreadsheet-like interface, outputting the effect size and value of power corresponding to the input parameters, including predictor variables, sample size, alpha, and error type.

Investigates the relationship between type of reading instruction and reading comprehension. Uses predictor variables including IQ, group, race, and comprehension pretest score to predict comprehension score. Finds that the dependent variable was not significantly related to method of reading instruction, and there was no interaction effect…

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…

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 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…

This paper draws on a part of the doctoral research study that investigates the potential impacts of Internet café use on Turkish college students' social capital. In this study, Internet café usage was portrayed by the amount of time spent and the frequency of online activities engaged at the cafés. Social capital, on the other hand, was…

This study determined how multiple ecodevelopmental domains influenced dysphoria in a community sample of Latina adolescents. Risk factors tested include childhood maltreatment, parental alcohol-related problems, and polysubstance problems. Protective factors include general self-efficacy, social conformity, and family connection. Female…

The 2000 US presidential election between Al Gore and George W. Bush has been the most intriguing and controversial in American history. Using the Florida ballot data, Wu showed that the 2000 election result could have been reversed had the "butterfly ballot effect" been eliminated. Through a combinatorial approach, Harger concluded that…

This study examined the relationship between problem-solving ability and study behavior of secondary school students in Southwestern Nigeria. A total of 430 SS 3 students randomly selected from fifteen secondary schools in Southwestern Nigeria participated in the study. A Problem-Solving Inventory and a Study Behaviour Inventory were employed in…

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)
