Test-retest reliability of a battery of field-based health-related fitness measures for adolescents

The main aim of this study was to determine the test-retest reliability of existing tests of health-related fitness. Participants (mean age 14.8 years, s?=?0.4) were 42 boys and 26 girls who completed the study assessments on two occasions separated by one week. The following tests were conducted: bioelectrical impedance analysis (BIA) to calculate percent body fat, leg dynamometer, 90° push-up, 7-stage sit-up, and wall squat tests. Intra-class correlation (ICC), paired samples t-tests, and typical error expressed as a coefficient of variation were calculated. The mean percent body fat intra-class correlation coefficient was similar for boys (ICC?=?0.95) and girls (ICC?=?0.93), but the mean coefficient of variation was considerably higher for boys than girls (22.2% vs. 12.2%). The boys' coefficients of variation for the tests of muscular fitness ranged from 9.0% for the leg dynamometer test to 26.5% for the timed wall squat test. The girls' coefficients of variation ranged from 17.1% for the sit-up test to 21.4% for the push-up test. Although the BIA machine produced reliable estimates of percent body fat, the tests of muscular fitness resulted in high systematic error, suggesting that these measures may require an extensive familiarization phase before the results can be considered reliable.     

Perfectionism and perceptions of parenting styles in male youth soccer

Although perfectionist orientations have been linked to a variety of cognitive, affective, and behavioral correlates in youth sport, little is known about antecedent factors that may influence adolescent athletes' perfectionist orientations. The purpose of this study was to determine whether perceptions of parenting styles differ as a function of adolescent athletes' perfectionist orientations. A total of 194 male youth soccer players (M age = 13.64 years; SD = 1.51; range, 10.67-16.25 years) completed measures of their perfectionist orientations in sport and of their perceptions of maternal and paternal parenting styles. Scores from the parenting style measure were calculated such that higher scores were reflective of higher parental authoritativeness (as perceived by the athletes). Cluster analyses conducted on perfectionism responses produced independent clusters of unhealthy perfectionists, healthy perfectionists, and nonperfectionists. MANOVA results revealed that both healthy- and nonperfectionists had significantly higher perceptions of maternal and paternal authoritativeness than unhealthy perfectionists (ps < .005). Results indicate that exposure to heightened authoritative parenting may play a role in developing healthy perfectionist orientations (or decrease the likelihood of developing unhealthy perfectionist orientations) in youth sport.     

Revitalizing the Field of Educational Foundations and PK–20 Educators' Commitment to Social Justice and Issues of Equity in an Age of Neoliberalism

In this article, we situate the imminent extinction of educational foundations within larger macro contexts, including the corporate control of knowledge production, the marginalization of critical academics who challenge the social, economic, and political status quos, and the global (United States in particular) economic recession. We also reaffirm why the field of educational foundations is important for this particular historical moment. In an effort to fight neoliberalism's stranglehold on PK–20 education, we provide guideposts for other like-minded critical educators. Specifically, these guideposts speak to why educational foundations are (despite their maltreatment and marginalization) an integral part to PK–12 teacher preparation and provide a call to action requiring educational foundations faculty members to inform those who still do not know that schools serve to reinforce the existing power, political, race, and economic relations.     

The Role of the Community College in Providing Language,Speech, and Hearing Services

Abstract

A survey of community college personnel in Connecticut, New York, and New Jersey was conducted to determine (1) the extent and type of services in speech, hearing, or language screening, remediation, and improvement, (2) the extent and type of instruction in speech and language improvement, and (3) the extent and type of bilingual services in speech, hearing or language presently offered to students and community members within the community college setting. In addition, the existence of plans to offer these services in the future was ascertained. Responses indicated the existence of some services but a general unavailability of comprehensive screening, evaluation, and rehabilitation programs despite the widespread needs of the growing community college constituency. The results of the survey can assist community college personnel in needs assessment and planning within their own institutions by offering a context for consideration of the priority for providing language, speech, and hearing services within the community college setting.     

Using Exploratory Bifactor Analysis to Understand the Latent Structure of Multidimensional Psychological Measures: An Example Featuring the WISC-V

Exploratory bifactor analysis (EBFA) represents a methodological advancement for implementing a bifactor model in exploratory factor analysis (EFA). However, little is known about how to properly employ the procedure. The current rotation criteria available for EBFA make it more likely to “get stuck” in local minima, contributing to possible group factor collapse, than more traditional EFA rotations. Thus, getting a proper solution is a more complex and involved process than typical EFA and may require a sensitivity analysis. This article examines EBFA through a sensitivity analysis and subsequent simulation of parameters thought to contribute to group factor collapse. Results support the use of sensitivity analysis, as the problematic variable was shown to greatly increase the likelihood of factor collapse. The hypothesis that estimation start values contribute to factor collapse was not supported. Accompanying R syntax for all analyses are provided to facilitate reproducibility.     

Two Great Problems of Learning

Two great problems of learning confront humanity: learning about the universe, and learning how to live wisely. The first problem was solved with the creation of modern science, but the second problem has not yet been solved. This combination puts humanity into a situation of unprecedented danger. In order to solve the problem we need to learn from our solution to the first problem. This requires that we bring about a revolution in the overall aims and methods of academic inquiry, so that it takes up its proper task of promoting wisdom.     

Networked professional development: Issues and strategies in current practice

The Computer Based Collaborative Group Work (CBCGW) Project is an institutional Teaching and Learning Technology Programme (TLTP) Project based in the Department of Educational Studies. The Project aims to support those within and beyond institutional boundaries in the exploration and uptake of collaborative work in a networked environment. This paper reviews examples of current practices in online professional development from around the world and considers some of the issues for providers of academic support. This will in turn be used to contextualize the response to these needs being developed by the Project.     

Denying rumors of organizational change: A higher source is not always better

Source appropriateness in denying rumors of organizational change was investigated in a laboratory context. As predicted, results revealed that the denial by the source highest in organizational position was not the most effective. Instead, the source most successful in reducing anxiety associated with the rumor and belief in the rumor was the one whose position level matched the scope of the rumor.
