In this study we examined the contexts and practices of 6 Vermont schools whose students met or exceeded standards set for performance on statewide reading tests administered at second and fourth grade. Demographic data on all elementary schools in Vermont were used in a cluster analysis to identify schools serving low-, middle-, and…

This article compares two methods for analyzing small sets of repeated measures data under normal and non-normal heteroscedastic conditions: a mixed model approach with the Kenward-Roger correction and a multivariate extension of the modified Brown-Forsythe (BF) test. These procedures differ in their assumptions about the covariance structure of…

Finnish students' multiliteracy profiles are examined from the perspectives of both traditional printed reading and Internet activities in the light of the data collected as a national option integrated into the Programme for International Student Assessment (PISA) 2000 study. After reciting some previous findings on reader profiles as revealed by…

This study explored a career readiness typology of 629 8th-grade students using the Career Factors Inventory. Data revealed developmentally appropriate elevated needs for information, specifically self-knowledge. In addition, cluster analysis demonstrated the heterogeneity of career development needs of 8th-grade students. Typal membership…

Advances in molecular genetics have provided behavioral scientists with a means of investigating the influence of genetic factors on human behavior. Unfortunately, recent candidate gene studies have produced inconsistent results, and a frequent scapegoat for the lack of replication across studies is the threat of population stratification. This…

The main purpose of this study is to examine the content structure of the Multistate Bar Examination (MBE) using the "table of specifications" model from the perspective of multivariate generalizability theory. Specifically, using MBE data collected over different years (six administrations: three from the February test and three from July test),…

Value priorities and educational value patterns are explored in respect to university students' active membership to religious and political groups. The sample was 117 students of the University of Athens, Greece, with 39 of them being active members of Christian Orthodox religious groups, 34 active members of political groups or unions, and 44…

Using stereotypes, researchers have predicted that novelty seeking declines in adulthood. Through this cross-sectional study, the authors revealed that only the external sensational type of novelty seeking declined, whereas the internal sensational and internal and external cognitive types remained stable or increased. A population of 233 adults…

This study compared the relative accuracy of (a) single Occupational Scale (OS) scores on the Strong Interest Inventory (SII) and (b) multiple-predictor scoring functions for discriminating members of nine occupations from people-in-general. The functions were constructed using discriminant function analysis with 4797 adults drawn from criterion…

Item bias is a major threat to measurement validity. Methods for detecting differential item functioning (DIF) are now commonly used to identify potentially biased items. DIF detection methods for dichotomous items are well developed, but those for ordinal items are less well developed. In this article, the authors compare four methods for…

Cluster analysis identified 3 groups of individuals who differed systematically on attributions of relative importance to work and to family roles. Participants were 213 married computer workers and lawyers, 126 men and 87 women. Questionnaires gathered data on attributions of importance to life roles, work-family conflict, spousal and managerial…

The present study examined whether school psychologists who serve a single school ("In-House" group) differed from school psychologists who serve several schools concurrently ("Traditional" group) in the three areas of job satisfaction, burnout, and effectiveness as perceived by the school psychologist. A total of 63 school psychology…

Four identity dimensions (Commitment Making, Identification with Commitment, Exploration in Depth, and Exploration in Breadth) were used to derive identity statuses by means of cluster analysis in a sample of late adolescents. This strategy resulted in both a qualitative refinement and a quantitative extension of Marcia's (1966) model. Five…

This research brief presents the results of an extensive review of research studies to identify maternal and family antecedents (conditions and characteristics before and during pregnancy) of healthy infant and child outcomes. The researchers identified seven major categories of antecedents associated with a strong start in life: the mother's…
