Factorial validity of the Reynolds Intellectual Assessment Scales for referred students

The Reynolds Intellectual Assessment Scales (RIAS) is a recently developed, individually administered psychometric instrument designed to measure general cognitive ability, as well as verbal (crystallized) intelligence, nonverbal (fluid) intelligence, and memory. Test reviewers have recommended the use of the RIAS despite the fact that, although the RIAS has been in circulation for more than four years, there is a paucity of independent research published about its psychometric properties. The purpose of the current study was to examine the factor structure of the RIAS across three samples of school‐age children: the RIAS norming sample; the data reported by Nelson, Canivez, Lindstrom, and Hatt; and a new, independent sample of students referred for special education services. Using confirmatory factor analytic techniques, this study found that a two‐factor model, positing verbal and nonverbal factors, fit all three data sets better than a one‐factor model. Furthermore, the two‐factor model demonstrated partial measurement invariance across the three samples, although the verbal factor showed much stronger invariance, construct reliability, and overall interpretability than did the nonverbal factor. Implications of this study for practitioners are discussed. © 2009 Wiley Periodicals, Inc.     

Social identity theories and educational engagement

There is a large body of research in studies of schooling, particularly ethnographic case studies, which posits that collective action among students undermines engagement in school and contributes to educational inequality. In this paper I review studies of engagement from a social identity theory perspective. To what extent can collective action explain why some student groups are less engaged than others? I discuss four approaches to identifying social identity‐related problems of engagement frequently used in prior research. While researchers often find problems of engagement among low‐academic‐status students, research on educational engagement has had difficulty locating the underlying causes of inequality in student engagement. Social identity theories of educational engagement are inherently theories of collective action. I conclude that a fifth approach, large‐scale observational studies of monitoring and sanctioning, provides the best framework for identifying both the prevalence of, and solutions to, this particular source of disengagement.     

Social network analysis: a simple but powerful tool for identifying teacher leaders

Instructional teacher leadership is central to a vision of distributed leadership. However, identifying instructional teacher leaders can be a daunting task, particularly for administrators who find themselves either newly appointed or faced with high staff turnover. This article describes the use of social network analysis (SNA), a simple but powerful tool that can help administrators better understand the connectedness of their network and pinpoint influential individuals within it. We offer practical guidance for conducting SNA, generating and modifying a sociogram, and interpreting the resultant data. Additionally, we suggest that information provided by SNA may be used to inform decisions about school/district programmes and policies.     

The effect of foil on paddling efficiency in a short surfboard

Surfboard volume and shape affect human performance while riding waves, but little is known regarding the impact of these variables on paddling, where surfers spend a majority of their time. The purpose of this study was to determine whether changing the foil (fore/aft thickness profile) of a short surfboard will alter paddling mechanics and efficiency if surfers are allowed to self-select their prone position. Twenty recreational surfers paddled three different surfboards in a freshwater swim flume while measurements of drag force, board motion, body position, heart rate, and oxygen use were acquired. All boards shared the same volume (31 L) and gross dimensions (172.7 cm long × 50.8 cm wide × 6 cm thick), but the geometric center was placed in a different location along the fore/aft axis of each board. Surfers were blinded to the volume and shape of each board. Results indicated that surfers positioned their center of mass further forward in response to a more nose-heavy board and further aft in response to a more tail-heavy board (22.04 ± 6.34 mm difference in position between boards, p = 0.008). This self-selected positioning yielded no statistical difference in drag force, board angle and accelerations, heart rate, or oxygen use across the three boards. These data suggest that when surfboard volume and gross dimensions are fixed, foil has little effect on the efficiency of paddling a short surfboard in recreational athletes.     

Mechanisms of social capital creation and consumption in a youth baseball league

Abstract

In this paper, I explore social capital creation within a youth baseball league in the American Southwest. Within, I first propose a parent typology that centres on the level of parental social and pragmatic involvement with their child’s team. Second, I examine that the specific facets of league structure facilitate relationship building among parents and volunteers within the league, including team creation, practices and games, all-star participation, volunteering, and player relationships, all of which play both a facilitating and constraining role in the types of relationships parents were prone to forming, and the social capital benefits that were likely to accrue within.     

P.S.: I Survived: An Activism Project to Increase Student and Community Trauma Awareness

Social work students created a community activism project to raise awareness about trauma prevalence and impact. Trauma theory describes silencing as the mechanism that hinders individual and community healing. Therefore, students sought to create an interactive opportunity to heighten trauma visibility on campus. They created a physical mailbox and invited community members respond to the prompt, “I am a survivor because …” and to read others’ responses. Through the project, students were able to document participants’ trauma experiences, increase community trauma awareness, and enhance their own learning. Moreover, the authors believe that this assignment successfully fostered student integration of micro and macro social work skills.     

Supporting the health library and information workforce

As a prelude to his keynote speech at the forthcoming Health Libraries Group conference, Sean McNamara, Head of CILIP Scotland, provides an insight into the work being undertaken with health librarians in Scotland and considers how CILIP Scotland might support the health information sector in the coming years.
