International trends in health science librarianship Part 9: the UK – Scotland and Wales

This is the 9th in a series of articles exploring international trends in health science librarianship. The previous article in this series looked at Northern Ireland and the Republic of Ireland. In this issue the focus is Scotland and Wales. There will be three or four more articles this year tracking trends in the Far East, Africa, South Asia and the Middle East. JM     

Examining relative age effects on performance achievement and participation rates in Masters athletes

Abstract

Although the relative age effect has been widely observed in youth sports (Musch & Grondin, 2001 Musch, J. and Grondin, S. 2001. Unequal competition as an impediment to personal development: A review of the relative age effect in sport. Developmental Review, 21: 147–167. [Crossref], [Web of Science ®] , [Google Scholar]), it is unclear whether it generalizes across the lifespan. The purpose of this study was to examine the relative age effect among a population of Masters athletes using archived data. Two successive studies examined the frequency of record-setting achievements (Study 1) and the frequency of participation entries (Study 2) at the US Masters track-and-field and swimming championships as a function of an individual's constituent year within any 5-year age category. Results of Study 1 indicated that the probability of setting a record increased if Masters athletes were in the first year, and decreased if they were in the third, fourth or fifth year, of an age category. Results of Study 2 indicated that the likelihood of participating in the National championships increased if Masters athletes were in the first or second year, and decreased if they were in the fourth or fifth year, of an age category. We highlight and discuss potential advantages afforded to Masters athletes who are relatively younger than their peers in the same 5-year age category.     

Gender,age, and sport differences in relative age effects among US Masters swimming and track and field athletes

Abstract

The aim of the present study was to examine elbow joint extension power-load characteristics with and without a countermovement. Eight male participants performed maximal elbow extensions with and without a countermovement against different loads (0, 2.5, 5.0, 7.5, 10.0, 12.5, and 15.0 kg). Electromyographic activity of the lateral and long heads of the triceps brachii and the biceps brachii muscles was recorded. The average joint power in the concentric phase was significantly enhanced in the countermovement condition at all loads except for 0 kg. The optimal load for the maximal joint power was greater in the countermovement (7.5 kg) than in the no countermovement condition (5.0 kg). Electromyographic activity was unchanged over the intensities and conditions. Our results suggest that the optimal load for the maximal joint power depends on the type of action (i.e. with or without a counter-movement), and that the enhanced joint power in the countermovement condition is due primarily to the storage and utilization of elastic energy.     

Trends in No Leisure-Time Physical Activity—United States, 1988–2010

Purpose: The aim of this study was to examine trends in the prevalence of no leisure-time physical activity (LTPA) from 1988 to 2010. Method: Using the Behavioral Risk Factor Surveillance System data, 35 states and the District of Columbia reported information on no LTPA from 1988 to 1994; all states reported no LTPA from 1996 to 2010. Results: No LTPA significantly declined over two decades. Prevalence for all states declined on an average of 0.6% per year from 29.1% in 1996 to 24.1% in 2004 and stabilized from 2005 to 2010, ranging from 24.0% to 25.4%. Prevalence declined for both sexes and all racial/ethnic groups. Conclusion: While the no LTPA trends improved over two decades, one in four U.S. adults still report they do not engage in LTPA.     

Faculty Organizational Commitment and Citizenship

Building on a theoretical framework that links characteristics of individuals and their work settings to organizational commitment (OC) and citizenship behavior, this study considers why faculty may be disengaging from institutional service. Analyses of survey data collected from a state system of higher education suggest that job characteristics, exchanges and social learning are associated with faculty members’ OC. For instance, opportunities for advancement and research support, as well as responsiveness of administrators to faculty, contributed to the likelihood that faculty would accept a position at their institution again if given the chance. Commitment, however, did not significantly affect time spent on institutional service. Two job characteristics—time spent on research and time spent on teaching—were negatively associated with this behavior.     

Linguistic Invention and Semantic Warrant Production: Elementary Teachers’ Interpretation of Graphs

In this qualitative study of mathematical discourse between elementary teachers, we examined linguistic invention and semantic warrant production as participants made successive attempts to communicate mathematical ideas. Linguistic invention is a creative practice of describing mathematics in terms of personal experience. We introduce semantic warrant production, which emerged as part of our analysis of substantial arguments produced by teachers learning mathematics. Participants engaged in linguistic invention and semantic warrant production to convince themselves and others of the validity of their mathematical inferences about a graph of rate of change versus time. Personal experiences that are taken-as-shared in a learning community can support accurate mathematical inference if connections between conventional language, common experiences, and mathematical representations are made explicit by learners.     

Grounds for health: the intersection of green school grounds and health‐promoting schools

Despite the growing body of research on green school grounds, relatively little has been written about their relationship with health promotion, particularly from a holistic health perspective. It is this relationship that we explore in this paper – the power and potential of green school grounds to promote health and well‐being and to be an integral element of multifaceted, school‐based health promotion strategies. Specifically, we bring together recent research to examine green school grounds as places where the interests of educators and children’s health advocates can meet, inform and support one another. By grounding our comments in recent thinking about health‐promoting schools, we highlight the growing body of evidence that green school grounds, as a school setting, can contribute to children’s physical, mental, social and spiritual well‐being.     

Precarity,food and accompaniment in community and youth work

Based on an ethnographic study of community-based learning and youth work in Greater Manchester, between 2013 and 2014, the use of food both as a response to precarity and a means of precaritisation is explored. The term ‘retrophilanthropy’ is used to analyse the paradoxical existence of social relations in community-based projects which feed whilst creating social abjection and divisions between the deserving and undeserving (in the practice of food charity of Foodbanks). This is contrasted with more ambivalent relationships encoded in food through youth work, termed contract and reward; enterprise and creativity; personalist orientations; and proto-universalist. It is argued that some aspects of these offer a prospect of more democratic forms of socio-cultural accompaniment and even a glimpse of the possibility of a more equal relationship to food.
