Predictive validity of the K-ABC for exceptional preschoolers

This 5-year follow-up study examined the predictive validity of the Kaufman Assessment Battery for Children (K-ABC) for 39 children identified during preschool as exhibiting language impairment (n = 10), behavior control deficits (n = 13), or normal language and behavioral development (n = 16). Mean age at follow-up was 9.75 years. The results generally supported the predictive validity of the K-ABC (p<.001). However, analyses by group indicated that the relationship between baseline K-ABC and follow-up K-ABC, language, and achievement measures for the language-impaired subjects was weak (p>.05). Although these results must be interpreted cautiously because of the small sample size, they suggest that for young children likely to be referred as at risk for future learning problems, the K-ABC may not be useful for prediction of later cognitive skills. Implications for practitioners are discussed.     

Adaptation and Pilot Testing of a Sexual Health Intervention for Female Survivors of Violence

Experiences of violence and behaviors that increase the risk of acquiring a sexually transmitted infection are high among women in the United States, and they often intersect (Meyer, Springer, &; Altice, 2011 Meyer, J. P., Springer, S. A., &; Altice, F. L. (2011). Substance abuse, violence, and HIV in women: A literature review of the syndemic. Journal of Women's Health (2002), 20(7), 991–1006. doi:10.1089/jwh.2010.2328[Crossref] , [Google Scholar]; Montgomery et al., 2015 Montgomery, B., Rompalo, A., Hughes, J., Wang, J., Haley, D., Soto-Torres, L., &; Hodder, S. (2015). Violence against women in selected areas of the united states.e1-e11.

Geneva, Switzerland: World Health Organization. [Google Scholar]). However, there are few evidence-based HIV-prevention interventions that address the special needs and challenges faced by female survivors of violence (Centers for Disease Control and Prevention, (CDC), 2017a Centers for Disease Control and Prevention. (2017a). Compendium of evidence-based interventions and best practices for HIV prevention. Atlanta, GA: Division of HIV/AIDS Prevention, National Center for HIV/AIDS, Viral Hepatitis, Sexual Transmitted Diseases and Tuberculosis Prevention. Retrieved from https://www.cdc.gov/hiv/research/interventionresearch/compendium/rr/index.html [Google Scholar]). To address this gap, we adapted and pilot-tested an existing evidence-based women-focused sexual risk-reduction intervention (The Future Is Ours) with 23 self-identified female survivors of violence. The intervention comprised eight-weekly, two-hour cognitive behavioral group sessions focusing on reducing sexual-risk and improving trauma-based coping skills. Using mixed-methods analyses, the adapted intervention was determined feasible and acceptable to participants, and preliminary results suggest that participation could reduce risk factors for sexually transmitted infections. Therefore, testing on a larger scale is warranted.

Regulatory policy as innovation: Constructing rules of engagement for a technological zone of tissue engineering in the European Union

This paper addresses the question of the part that regulation plays in processes of innovation in sectors of technology. The politico-economic phenomenon of ‘Europe’ is partly constituted by regulatory regime-building, and new technologies are one of the major sites of regime-building. A constructionist social theory perspective shows that study of the conflictual processes of regulatory policymaking affords insights into the formation of the rules of engagement that constitute technology domains. Adopting the concept of emergent ‘technological zone’ in preference to industrial ‘sector’ or technoscientific network, the paper presents, using empirical research, a detailed account of the case of the debate and development of regulatory policy for therapeutic tissue engineering in the European Union's policy institutions and stakeholder networks. It describes how the jurisdiction of an emergent zone has been formed through such negotiations, providing a counter-example to the common view that regulation ‘lags behind’ innovation. The analysis takes account particularly of the part played by the malleability of the definition of the material technology itself in such constructive governance processes, and it also suggests various consequences for the array of producers of the technology, for market structuring and for the innovation pathways taken by tissue engineering technology. Concluding, the paper argues that there is conceptual advance to be made by bringing together constructionist social theory with innovation studies approaches that highlight the part played by non-firm, public institutions in shaping innovation ecologies.     

How do students define their roles and responsibilities in online learning group projects?

The goal of this study was to explore the processes of group role formation in online class settings. Qualitative analysis was used to code chat logs and discussion threads in six undergraduate Family and Consumer Sciences online courses that required online group projects. Four themes related to the process of group role formation emerged: testing the waters, apologies as being nice, tag – you’re it, and struggling to find one’s role. Students created roles of leader, wannabe, spoiler, agreeable enabler, coat‐tails, and supportive worker as the group process evolved over the course of the semester. Results lend support for a balance between allowing students to create and experience roles on their own and faculty assignment of roles. Questions are raised related to faculty approaches toward directing and scaffolding the group process.     

Boundary Crossing and the Professional Learning of Teacher Educators in New International Contexts

In this collaborative self-study, two teacher educators examine their experiences of working in new international contexts and the impact of those experiences on their professional learning and identities. Mandi moved from a major research university in one country to another, while Judy co-led a group of pre-service teachers on an international practicum for three weeks each year for three years. Using the concept of boundary crossing as a theoretical and analytical framework, each teacher educator identified a boundary-related critical incident or experience that occurred during her work in new international contexts. Through individual and collaborative analysis of their critical incidents, they found that working as a teacher educator in new international contexts involves the crossing and re-crossing of multiple personal, professional, linguistic and cultural boundaries. Working in these boundary spaces involved learning how to negotiate new kinds of relationships with colleagues and students, manage changed roles and responsibilities and, ultimately, a search for a renewed sense of self, as each sought to understand herself differently within a new professional context.     

Stimuli that signal the absence of reinforcement are paid more attention than are irrelevant stimuli

According to established theories of attention (e.g., Mackintosh, 1975; Sutherland & Mackintosh, 1971), simple discriminations of the form AX+ BX- result in an increase in attention to stimuli A and B, which are relevant to the outcome that follows them, at the expense of X, which is irrelevant. Experiments that have apparently shown such changes in attention have failed to determine whether attention is enhanced to both A and B, which signal reinforcement and nonreinforcement, respectively, or just to A. In Experiments 1 and 2, pigeons were trained with a number of discriminations of the kind AX+ BX-, before compounds that had been consistently nonreinforced were involved in a subsequent discrimination. Both experiments provided support for theories that propose that more attention is paid to stimuli that consistently signal nonreinforcement than to irrelevant stimuli in simple discriminations.     

Understanding Constraints on Innovation in Physical Education

This paper describes and analyses Swedish curriculum theory and research in a 20year perspective in relation to the changes in the comprehensive school system and the decline of the welfare state. It is argued that the break-up of the strong triangle' between the educational research community, the former National Board of Education and the Ministry of Education, which was essential in the implementation of the comprehensive school in the 1960s and in the promotion of research and theory on the curriculum, began in the late 1970s and early 1980s. Some of the consequences of this change are analysed to highlight a changed agenda for curriculum theory and research in terms of a recontextualization not only of the curriculum objects but of curriculum theory and research itself.
