Dietary supplements

For the athlete training hard, nutritional supplements are often seen as promoting adaptations to training, allowing more consistent and intensive training by promoting recovery between training sessions, reducing interruptions to training because of illness or injury, and enhancing competitive performance. Surveys show that the prevalence of supplement use is widespread among sportsmen and women, but the use of few of these products is supported by a sound research base and some may even be harmful to the athlete. Special sports foods, including energy bars and sports drinks, have a real role to play, and some protein supplements and meal replacements may also be useful in some circumstances. Where there is a demonstrated deficiency of an essential nutrient, an increased intake from food or from supplementation may help, but many athletes ignore the need for caution in supplement use and take supplements in doses that are not necessary or may even be harmful. Some supplements do offer the prospect of improved performance; these include creatine, caffeine, bicarbonate and, perhaps, a very few others. There is no evidence that prohormones such as androstenedione are effective in enhancing muscle mass or strength, and these prohormones may result in negative health consequences, as well as positive drug tests. Contamination of supplements that may cause an athlete to fail a doping test is widespread.     

Individual differences in infant-mother attachment at twelve and eighteen months: stability and change in families under stress

100 economically disadvantaged mothers and their infants were observed in the Ainsworth and Wittig "strange situation" at 12 and 18 months. Infants were classified as secure, anxiously attached/avoidant, or anxiously attached/resistant. In addition, mothers reported occurrence of stressful events related to the stability of the caretaking environment during the 12--18 month period by completing a 44-item checklist concerning work, finances, family, neighbors, health, etc. 62 infants were assigned to the same attachment classification at both 12 and 18 months (p less than .01). Despite this stability, significantly more infants changes classification than in a recent study of stable middle-class families. With the present sample, anxious attachment was associated with less stable caretaking environments than secure attachment; change from secure to anxious attachment was associated with higher stressful-event scores than stable secure attachment.     

SIDE-VIEW: Evaluation of a system to develop team players and improve productivity in Internet collaborative learning groups

This paper briefly summarizes the initial development of a computer-supported collaborative learning environment and evaluates its effects in relation to the productivity of CSCL groups. The design of the SIDE-VIEW system is driven by the social identity approach to understanding group behaviour and is premised upon the need to establish congruity between the self-definition of group members and their collaborative learning tasks. We begin by outlining the rationale for the system in relation to productivity and the emergence of team players within collaborative learning groups. We then describe aspects of the design that are intended to enhance both, and report on a field trial of the initial prototype on international groups of higher education students. The preliminary results of the field study indicate that aspects of the design encourage the emergence and influence of team players within groups, with consequential improvements to the quality of the group output. The role of team players in CSCL groups is contrasted with that of group leaders.     

What Schools Need to Know About Fostering School Belonging: a Meta-analysis

Belonging is an essential aspect of psychological functioning. Schools offer unique opportunities to improve belonging for school-aged children. Research on school belonging, however, has been fragmented and diluted by inconsistency in the use of terminology. To resolve some of these inconsistencies, the current study uses meta-analysis of individual and social level factors that influence school belonging. These findings aim to provide guidance on the factors schools should emphasise to best support students. First, a systematic review identified 10 themes that influence school belonging at the student level during adolescence in educational settings (academic motivation, emotional stability, personal characteristics, parent support, peer support, teacher support, gender, race and ethnicity, extracurricular activities and environmental/school safety). Second, the average association between each of these themes and school belonging was meta-analytically examined across 51 studies (N?=?67,378). Teacher support and positive personal characteristics were the strongest predictors of school belonging. Results varied by geographic location, with effects generally stronger in rural than in urban locations. The findings may be useful in improving perceptions of school belonging for secondary students through the design of policy, pedagogy and teacher training, by encouraging school leaders and educators to build qualities within the students and change school systems and processes.     

Building an evolving method and materials for teaching legal writing in large classes

In South Africa and in other parts of the world, many professions are bemoaning the poor ability of many graduates to communicate their skills and knowledge effectively once they enter the workplace. Increasingly, pressure is placed on higher education to do more in terms of equipping future professionals with the necessary critical reading, research, thinking and writing skills the workplace demands. However, in South Africa especially, the demand for access to higher education is resulting in increased admissions, and in many lecturers standing in front of larger classes filled with students from a wide range of home and educational backgrounds with ‘variable’ commands of English as a medium of instruction and communication (Greenbaum and Mbali in S Afr Linguist Appl Lang Stud 20:233–244, 2002). This makes the task of equipping these students with disciplinary knowledge and skills a challenge. In responding to this challenge, the Law Faculty at the University of the Western Cape, in collaboration with a writing specialist, initiated a project aimed at transforming the way in which legal writing was taught at first year level. The overall aim was to start training students, from first year, to adapt their thinking and writing to the kinds of knowledge and practice required by academic study as well as the legal profession. The project was successful in achieving its modest aims, but certain challenges remain. This paper reflects critically on the development and evolution of the model for teaching legal writing in large classes. It argues that teaching legal writing in large classes requires creative and sustainable approaches so that students can become active and critical writers, readers and thinkers over time in this, or any, field.     

Using Young Adult Literature to Develop Content Knowledge of Autism for Preservice Teachers

This promising practice explores the use of young adult literature as a supplement to texts in an undergraduate introduction to a special education course. Literature portraying adolescent characters with autism spectrum disorder (ASD) were used to build schema of preservice teachers. Participants' knowledge and attitudes about ASD were examined before and after reading a young adult novel of their choice. Results indicated that students in the literature group out-performed peers in the control group on measures of ASD content. Exemplars of students' responses suggested students who read the novel expressed increased knowledge and interest, recognition of commonalities, and complex and nuanced views of ASD. Participant satisfaction with reading the novels outside of class was also high, suggesting students found the authentic literacy experience enjoyable.     

What do Our Faculty Use? An Interdisciplinary Citation Analysis Study

During the fall of 2012 and spring of 2013, two librarians from the University of Kansas Libraries conducted a citation analysis of faculty publications in three broad disciplinary areas: humanities, social sciences, and science. The main purpose of research was to find out if the library provides adequate support to faculty researchers. The authors confirmed that KU Libraries provide access to the majority of items used by campus researchers. In addition, the findings will be used in collection management decisions, such as demand driven acquisition. Finally, the authors analyzed additional citation analysis studies in order to establish external benchmarks for their results.

The Relationship between Understanding of the Nature of Science and Practice: The influence of teachers’ beliefs about education,teaching and learning

This paper reports the relationship between four English primary teachers’ understanding of the nature of science and their practice. Action research was included as a major part of the research design in order to explore the dialectical interplay between various factors at work in the teachers’ practice. The influences of both tacit and espoused understandings of the nature of science were considered alongside the teachers’ beliefs about education, teaching, and learning. These beliefs were found to be the determining factor in the teachers’ decisions about classroom strategies. In arguing for a dialectical perspective on teachers’ practice, the research suggests that teachers’ espoused understanding of the nature of science may also be at least partially formed by the influence of these beliefs, raising the possibility that influence may run from teaching to theoretical understanding and not the other way round.     

Collaboration and Action Research: a cautionary tale

Action research has become a widely accepted and recommended methodology for teacher research. With the current climate of collaborative planning within primary schools. it has been seen as a process which could exist naturally alongside such activity, with much being made in the rhetoric of its essentially ‘collaborative’ character. But such claims are problematic. They derive importantly from epistemological considerations, but weaknesses may be found in such arguments when they are considered against the reality of the process in action. This article considers the claims for the collaborative nature of action research in the context of the progress of a coordinated inquiry in a primary school, within which the author was involved. Whilst recognising their importance, it challenges the arguments for insisting on collaboration as a prerequisite for the most ‘effective’ action research, suggesting that all action research is fundamentally personal. It also raises the question of whether participation in the process may itself raise conflicts with the need for a collaborative structure to ensure critical reflection and valid knowledge claims, suggesting that action research may at times have effects at a personal level which could produce severe tensions in the maintenance of a collaborative situation.
