Science and the major racket sports: a review

The major racket sports include badminton, squash, table tennis and tennis. The growth of sports science and the commercialization of racket sports in recent years have focused attention on improved performance and this has led to a more detailed study and understanding of all aspects of racket sports. The aim here, therefore, is to review recent developments of the application of science to racket sports. The scientific disciplines of sports physiology and nutrition, notational analysis, sports biomechanics, sports medicine, sports engineering, sports psychology and motor skills are briefly considered in turn. It is evident from these reviews that a great deal of scientific endeavour has been applied to racket sports, but this is variable across both the racket sports and the scientific disciplines. A scientific approach has helped to: implement training programmes to improve players' fitness; guide players in nutritional and psychological preparation for play; inform players of the strategy and tactics used by themselves and their opponents; provide insight into the technical performance of skills; understand the effect of equipment on play; and accelerate the recovery from racket-arm injuries. Racket sports have also posed a unique challenge to scientists and have provided vehicles for developing scientific methodology. Racket sports provide a good model for investigating the interplay between aerobic and anaerobic metabolism and the effect of nutrition, heat and fatigue on performance. They have driven the development of mathematical solutions for multi-segment interactions within the racket arm during the performance of shots, which have contributed to our understanding of the mechanisms of both performance and injury. They have provided a unique challenge to sports engineers in relation to equipment performance and interaction with the player. Racket sports have encouraged developments in notational analysis both in terms of analytical procedures and the conceptualization of strategy and tactics. Racket sports have provided a vehicle for investigating fast interceptive actions, hand-eye coordination and perception-action coupling in the field of motor control. In conclusion, science has contributed considerably to our knowledge and understanding of racket sports, and racket sports have contributed to science by providing unique challenges to researchers.     

48 million configurations and counting: platform numbers and their capitalization

Platforms are important actors in contemporary cultural economic processes. They include social network sites, online content management systems, streaming media platforms, mobile communication infrastructures, supply chain logistics solutions, and cryptocurrencies. Analysis of platforms and their capitalization should take into account the ways they structure social practice as assets and the constitutive opacity of platforms as configured realities. It explores capitalization by focusing on the problems of counting people and things on platforms. Via a case study of the software repository platform [Github.com] (https://github.com), it analyzes how 'platform numbers’ participate in capitalization. It describes attempts to enumerate the elements of the platform by counting, mapping or listing them. The paper shows how attempts to enumerate people and things encounter forms of association, duplication, combination, imitation and configuration that are crucial to the ensemble but remain refractory to capitalization. It proposes configurative enumeration of the platform numbers as a way of conceptualizing these un-enacted excesses. In a configurative enumeration, the composition, the rhythms of imitation, variation and commutation, and constant relating, repairing and adjusting of configurations crucial to the ongoing formation of platforms come into view. Configurative enumerations engage the inventive realities of platformization, realities that precede and sometimes overflow their capitalization.     

AN INTERVIEW WITH KIMMO LEHTONEN

In this interview, Dr. Kimmo Lehtonen discusses the current “state of the art” regarding creativity in Scandinavia, Europe, and around the world. He explores the training of teachers, prodigies, and art and music therapy. Dr. Lehtonen examines the issue of computers relative to creativity and various theoretical explanations for the phenomenon of creativity. Personality factors are examined and explored, and future concerns are delineated.     

Student intrinsic motivation,science teaching practices and student learning

Conclusion This paper has been concerned with the application of basic understandings about intrinsic motivation and curiosity behaviour to the teaching of science, and in particular senior high school biology. The important role of student knowledge in the generation, maintenance and resolution of cognitive conflict is congruent with the renewed interest in studying students' everyday knowledge of curriculum content. However the study of classroom teaching processes in terms of their facilitation of intrinsic motivation is not common. Yet the data collected in this study demonstrates the importance of closely examining the implementation of courses such as the Web of Life, if the arousal of intrinsic motivation is an intended student outcome. Both interview and observational data indicated that the teaching styles adopted by teachers in this study were not likely to engender curiosity amongst students. Perhaps this should be expected. The use of a wide range of reference materials to investigate problems that arise in the classroom, the encouragement of students to do additional work on a topic if they are particularly interested, and a willingness on the part of the teacher to allow students sufficient time to formulate their own solutions to problems are classroom processes which necessitate a greater flexibility in curriculum presentation than can be often tolerated by teacher and school management. Such processes may be incompatible with organisational properties of the school and the pressures often placed upon students to perform to a high standard on rigidly defined examinations.     

Changing the way people think about health-enhancing physical activity: do mass media campaigns have a role?

Mass media campaigns are conducted to influence community norms around health behaviours, including physical activity. Campaigns can reach large populations at relatively low cost, to influence awareness, knowledge and beliefs through to intention and behaviour change. We reviewed 15 campaigns with an explicit focus on physical activity, and explored impacts upon a range of proximal and distal variables. Campaigns achieved high recall, with a median of 70% of the target group aware of the campaign. Increases in knowledge or attitudes to physical activity were found among half the campaigns that reported this measure. Few campaigns reported other proximal variables, such as saliency, beliefs, self-efficacy or behavioural intention. Increases in physical activity were reported among motivated sub-groups of volunteers, but few campaigns reported population increases in activity. Campaigns increase awareness of the issue of physical activity but may not have a population-level effect on behaviour. Campaigns should focus more on influencing proximal variables, such as social norms, to bring about long-term behaviour change. This should be seen as part of a broader strategy, including policy and environmental change. Evaluation designs that measure the full range of variables are preferred to an over-concentration on behaviour alone.     

A 5-star system for rating the quality of information based on DISCERN

Objective: To develop an explicit scheme for calculating a 5‐star quality rating for consumer health information, and to test if there is good agreement be tween this and the final DISCERN quality question. Design: A sample of 15 consumers and health professionals rated 26 health information leaflets covering a broad range of conditions and treatments using two new 5‐star‐rating schemes and the existing DISCERN final quality rating. Each scheme is based on the 15 DISCERN criteria, but the 5‐star schemes provide more explicit methods for summarizing overall quality. The level of agreement between the three different rating systems was compared using Kappa scores with quadratic weights. Participants were also asked to complete a brief questionnaire that was designed to elicit their views on using a visual summary of the quality of health information. Results: The level of agreement between each 5‐star‐rating system and the existing DISCERN quality rating question was high (kappa = 0.86, 95% CI 0.83–0.89 in both instances). Seventy‐seven per cent of the sample preferred the second star‐rating scheme, and 80% reported they would use such a scheme. Conclusion: Assigning a single quality score using an explicit scoring scheme (represented by stars) based on answers to the DISCERN questionnaire is a reliable and valid way of rating consumer health information.     

Lay perceptions of collectives at the outbreak of the H1N1 epidemic: heroes, villains and victims

Lay perceptions of collectives (e.g., groups, organizations, countries) implicated in the 2009 H1N1 outbreak were studied. Collectives serve symbolic functions to help laypersons make sense of the uncertainty involved in a disease outbreak. We argue that lay representations are dramatized, featuring characters like heroes, villains and victims. In interviews conducted soon after the outbreak, 47 Swiss respondents discussed the risk posed by H1N1, its origins and effects, and protective measures. Countries were the most frequent collectives mentioned. Poor, underdeveloped countries were depicted as victims, albeit ambivalently, as they were viewed as partly responsible for their own plight. Experts (physicians, researchers) and political and health authorities were depicted as heroes. Two villains emerged: the media (viewed as fear mongering or as a puppet serving powerful interests) and private corporations (e.g., the pharmaceutical industry). Laypersons' framing of disease threat diverges substantially from official perspectives.     

Cultures of Undergraduate Teaching at Research Universities

Teaching-oriented faculty have received scant attention as a distinctive cultural force. Even among those who would speak on their behalf, undergraduate teachers have been treated as little more than a dependable workforce whose interests are best served by top-down proposals for enhanced recognition and reward. Findings from a five-campus study suggest a more complex reality. Of particular interest is an explicitly oppositional culture that questions both the Scholarship of Teaching model and the ethos of competitive achievement. These views echo the longstanding populist tradition within American higher education and represent a potential counterforce to the recent narrowing of faculty roles.     

Evaluation of Courses by Whole Student Cohorts: a case study

In a climate of unprecedented change in higher education (HE), accurate and immediate course feedback information is vital to the management of institutions, in assisting the development of course material relevant to present student needs. Student contribution to qualitative course evaluation is commonplace although use of relatively small representative groups of students is usual. However, with class sizes increasing — between 100 and 200 is now common — the ability to acquire accurate qualitative evaluation, representatively, is a major issue. This paper describes a methodology providing opportunity for whole cohort groups of students to be involved simultaneously in the generation of feedback. It considers the effectiveness of student consultation meetings as a collection method, the utility of the results in the course development process, how the issues raised and discussed compare with matters included on a university‐wide questionnaire, and whether participating students feel inhibited in discussing matters so publicly.
