Testing Factorial Invariance With Unbalanced Samples

In testing the factorial invariance of a measure across groups, the groups are often of different sizes. Large imbalances in group size might affect the results of factorial invariance studies and lead to incorrect conclusions of invariance because the fit function in multiple-group factor analysis includes a weighting by group sample size. The implication is that violations of invariance might not be detected if the sample sizes of the 2 groups are severely unbalanced. In this study, we examined the effects of group size differences on results of factorial invariance tests, proposed a subsampling method to address unbalanced sample size issue in factorial invariance studies, and evaluated the proposed approach in various simulation conditions. Our findings confirm that violations of invariance might be masked in the case of severely unbalanced group size conditions and support the use of the proposed subsampling method to obtain accurate results for invariance studies.     

Huber Inventory of Trainee Self‐efficacy: Assessment of measurement models

The purpose of this study was to further examine the factor structure of the Huber Inventory of Trainee Self‐Efficacy (HITS), a measure of school psychology trainee self‐efficacy. Lockwood et al. (2017, Psychol. Sch., Vol. 54, pp. 655–670) extant data set, collected from 520 school psychology trainees, was utilized. Four measurement models were examined for model fit and factor loadings. Of the four models, a bifactor model with a single latent general self‐efficacy (GSE) and latent domain‐specific factors (i.e., Multidimensional Assessment Skills, Counseling Skills, Professional Interpersonal Skills, and Research Skills) was the most parsimonious. However, standardized loadings indicated that all practice‐related items loaded more significantly onto GSE than their domain‐specific factors, indicating the utility of GSE for practice‐related skills. Of note, the Research Skills factor displayed greater domain‐specific loadings than general loadings. These findings suggest that GSE may be the best indicator of trainee self‐efficacy, though a two‐factor model that represents practical skills versus research skills may also be appropriate. Additionally, reliability scores indicate that subscale interpretation may also be reasonable. Limitations, implications for trainers of school psychologists, and for future research directions are discussed.     

Optoelectrofluidic field separation based on light-intensity gradients

Optoelectrofluidic field separation (OEFS) of particles under light -intensity gradient (LIG) is reported, where the LIG illumination on the photoconductive layer converts the short-ranged dielectrophoresis (DEP) force to the long-ranged one. The long-ranged DEP force can compete with the hydrodynamic force by alternating current electro-osmosis (ACEO) over the entire illumination area for realizing effective field separation of particles. In the OEFS system, the codirectional illumination and observation induce the levitation effect, compensating the attenuation of the DEP force under LIG illumination by slightly floating particles from the surface. Results of the field separation and concentration of diverse particle pairs (0.82–16 μm) are well demonstrated, and conditions determining the critical radius and effective particle manipulation are discussed. The OEFS with codirectional LIG strategy could be a promising particle manipulation method in many applications where a rapid manipulation of biological cells and particles over the entire working area are of interest.     

Varying criticality of key success factors of national e-Strategy along the status of economic development of nations

Many studies mention the importance of national e-Strategy as it is a vital contributing factor for ICT-enabled development. However, it is difficult to find a conceptual framework that suggests how the national e-Strategy should be defined and applied by the target country. This creates more confusion for policy makers. This paper reviews previous research on national e-Strategies to recognize its significance as a major contributing factor. Based on that, this research defines the critical success factors of national e-Strategy and investigates the possibility of prioritizing factors by the scale of economy through a Delphi survey. By reviewing the evaluated status of e-Readiness and co-relating the evaluation with economic status, we may further investigate the significance of the digital divide and national e-Strategy. The outcome of this research may be applicable in differentiating critical success factors from general ingredients of National e-Strategy.     

The geography of school choice in a city with growing inequality: the case of Vancouver

This analysis aims to measure the impact of school choice policy on secondary school students’ enrolment patterns within the social geography of Vancouver, an increasingly polarized global city. The rationale for the study is to examine the impact of ‘education market’ reforms on the socio-economic composition of schools in a Canadian context, where a social welfare commitment to educational equality is being replaced by market-oriented policies and increasing social inequality. Our study is guided by Bourdieu’s theory of site in considering whether growing inequality and polarization of wealth in a city are correlated with the ways families choose schools. We apply a geographical methodology (Geographic Information System) to delineate spatial patterns of choosing schools. Our analysis shows that those who opt out of the under-subscribed schools come from the neighborhoods with relatively higher capital than those who remain in their assigned schools. Also, those who opt into the over-subscribed schools in the affluent areas come from the neighborhoods with above-average levels of capital in Vancouver. Overall, we find that the spatial inequality in school choice generally follows the uneven distribution of capital/wealth across the city. The pattern of student mobility indicates an increasing level of segregation.     

Sensitivity and precision of adverse effects search filters in MEDLINE and EMBASE: a case study of fractures with thiazolidinediones

Background: Search filters have been developed in MEDLINE and EMBASE to help overcome the challenges of searching electronic databases for information on adverse effects. However, little evaluation of their effectiveness has been carried out. Objectives: To measure the sensitivity and precision of available adverse effects search filters in MEDLINE and EMBASE. Methods: A case study systematic review of fracture related adverse effects associated with the use of thiazolidinediones was used. Twelve MEDLINE search strategies and three EMBASE search strategies were tested. Results: Nineteen relevant references from MEDLINE and 24 from EMBASE were included in the review. Four search filters in MEDLINE achieved high sensitivity (95 or 100%) with an improved level of precision from searches without any adverse effects filter. High precision in MEDLINE could also be achieved (up to 53%) using search filters that rely on Medical Subject Headings. No search filter in EMBASE achieved high precision (all were under 5%) and the highest sensitivity in EMBASE was 83%. Conclusions: Adverse effects search filters appear to be effective in MEDLINE for achieving either high sensitivity or high precision. Search filters in EMBASE, however, do not appear as effective, particularly in improving precision.     

Critical Issues in Teaching a Multicultural Counseling Course

A Multicultural Counseling course (MCC) brings unique challenges and rewards to both instructors and students. Given its unique challenges, the process of teaching a MCC is as important as, or even more important than, the content. Drawing from extant literature and the authors’ experiences, this paper discusses such topics as what to teach, how to teach, classroom dynamics, instructors’ issues, and students’ issues to provide a concise, practical, and comprehensive framework for teaching such difficult but essential courses.     

Being Black, Male, and Gifted in Miami: Prevalence and Predictors of Placement in Elementary School Gifted Education Programs

Although it is well established that Black male students are underrepresented in gifted educational programs in the United States, due to a scarcity of longitudinal prospective research, little is known about the protective factors at the child, family, and school level that increase the probability of Black male students being identified as gifted during early elementary school. Using data from the Miami School Readiness Project, we followed 6,926 low-income Black males from preschool through 5th grade to describe trajectories for the 453 Black males (6.5 %) who were identified as gifted, and examined child, family, and preschool variables associated with gifted classification. Boys were most commonly identified as gifted in first and second grade, and 15 % of the identified boys did not appear to be receiving gifted courses. Hierarchical multiple logistic regression analyses revealed that being classified as gifted in early elementary school was more likely for Black males who (a) attended public school pre-K programs at age four, (b) had higher cognitive, language, fine motor, behavioral, and emergent literacy school readiness skills before entering kindergarten, (c) spoke a language other than English at home, (d) were older upon entering kindergarten, (e) received higher grades in school, and (f) scored higher on standardized tests of math and reading. Predictors of gifted identification in the kindergarten year were different and weaker compared to identification in later years. Implications for early identification and intervention for talented Black males are discussed.     

Are Graduating Students Ready for Financial Aspects of Social Work Practice?

ABSTRACT

Graduating students must be prepared with knowledge and skills for the financial aspects of social work practice. This study examines graduating students’ attitudes and perceptions about client finances, as well as their financial knowledge. Internet survey results (n = 116) of BSW and MSW graduating students indicate that respondents (a) perceive a limited function for discussing client financial circumstances in practice, (b) understand the relevance, however, of client finances, (c) are unprepared to address this aspect, and (d) are supportive of integrating this content into required policy and practice courses. Teaching and curricular implications, along with programmatic recommendations, are included.
