This study attempts to clarify conceptual and operational inconsistencies in the literature around "Ghiselli's hobo syndrome." I propose that defining characteristics of hobo syndrome should include both the exhibition of frequent job movement behavior and positive attitudes about such behavior. This definition effectively differentiates…

Caregivers often struggle with food neophobia on the part of young children. This study examined whether labeling novel healthy foods with fun names would increase children's willingness to try those foods and encourage them to eat more of those foods in a child care setting. Thirty-nine toddler and preschool age children (mean age = 3.9 years)…

Sexual social exchange theory was applied to perceptions of a date rape by manipulating the cost of the date and who paid in vignettes presented to 188 U.S. college students, who then rated the characters' sexual expectations, blame, responsibility, and rape justifiability. Findings from this between-participant design partially supported…

This mixed-method study examines (1) the extent to which fifty adolescents receiving wraparound treatment and prescribed psychotropic medication for various psychiatric disorders report that they would continue taking medication if the decision was entirely their own (termed "medication commitment"); (2) their general subjective experiences with…

A large school-based sample of 9th-grade adolescents (N = 875) completed the Almost Perfect Scale-Revised (APS-R; Slaney, Mobley, Trippi, Ashby, & Johnson, 1996). Decision rules and cut-scores were developed and replicated that classify adolescents as one of two kinds of perfectionists (adaptive or maladaptive) or as nonperfectionists. A…

We focus on the identification of differential item functioning (DIF) when more than two groups of examinees are considered. We propose to consider items as elements of a multivariate space, where DIF items are outlying elements. Following this approach, the situation of multiple groups is a quite natural case. A robust statistics technique is…

The Flynn effect, a secular rise in IQ seen throughout the world, was examined on the WISC-R and WISC-III subtests in a longitudinal sample of more than 2,500 school children who were tested between 1974 and 2002. Multivariate analysis of variance and multiple regression analyses revealed that all the subtests experienced significant decreases in…

This dissertation research describes an investigation that explores the nature of the relationship between participation in evaluation and the use of evaluation findings and processes within three large-scale multisite evaluations. The purpose of this study is to test whether assumptions and theories about participation translate into evaluation…

The purpose of this study was to investigate the influence of cold-water immersion on kinematics and kinetics during a drop-landing task. On four separate occasions, 9 men performed drop-landings from a 0.6-m platform to a force platform following 30-min immersion to the hip-joint in thermoneutral water (control; 34 [degrees]C) and in cold water…

Dimensionality is an important assumption in item response theory (IRT). Principal component analysis on standardized residuals has been used to check dimensionality, especially under the family of Rasch models. It has been suggested that an eigenvalue greater than 1.5 for the first eigenvalue signifies a violation of unidimensionality when there…

This study is based upon the conceptual linking of the multidimensional and multi-focal nature of work-related commitment. The main aims of our study were to create, through K-means cluster analysis, commitment profiles based on the three components of organizational and occupational commitment, and to examine their joint effect on key work…

A scaled difference test statistic T[tilde][subscript d] that can be computed from standard software of structural equation models (SEM) by hand calculations was proposed in Satorra and Bentler (Psychometrika 66:507-514, 2001). The statistic T[tilde][subscript d] is asymptotically equivalent to the scaled difference test statistic T[bar][subscript…

We examined the degree of dependence between standardized-mean-difference effect sizes in multiple-treatment studies in meta-analysis in terms of the correlation formula provided by Gleser and Olkin (1994). To explore the impact of group size and the values of the true multiple-treatment effect sizes, we simplified the formula for the correlation…

This study examined preservice teacher attitudes toward and expected technology integration practices as compared to in-service teachers' attitudes toward and actual (self-reported) practice of technology integration. The preservice teachers revealed a greater level of confidence in their ability to integrate technology and more positive beliefs…

Ausubel and Novak's construct of "meaningful learning" stipulates that substantive connections between new knowledge and what is already known requires the integration of thinking, feeling, and performance (Novak J. D., (2010), "Learning, creating, and using knowledge: concept maps as facilitative tools in schools and…
