The secret life of the chemical bond: students’ anthropomorphic and animistic references to bonding

This paper discusses students’ use of anthropomorphic language in science, and in particular calls upon some examples from research into student understanding of chemical bonding. It is argued that anthropomorphic language is common amongst scientists as well as science students. A simple classification of such instances is suggested to distinguish between those examples that are useful in aiding communication and understanding, and those which merely stand in place of such understanding.     

Globalisation,modernisation and competitiveness: A critique of the new labour project in education

In this article, the author begins by examining the ubiquitous concept of 'globalisation' - a key theme of the New Labour Government. He question whether developments named as such are as widespread as proclaimed and whether the assumptions underlying the concept are misleading and occlude more than they reveal. The author concludes that, rather than 'globalisation' being viewed as a new epoch, the global movement of capital, which informs and underpins the globalisation thesis, might more accurately be described as an ongoing process, one which began 400-500 years ago. 'Globalisation', however, he suggests, is used ideologically to justify the New Labour programme, or the 'Third Way', which has two major anchors; competitiveness and modernisation. The former entails an economy in which everyone works, where the need for the untrammelled expansion of the free market is promoted as natural and inevitable and where there is the requirement for flexibility in the labour market and for low wages, in the context of the diminution of the welfare state. Since Keynesian demand management has been abandoned, one of the few strategic levers available to the New Labour Government to achieve these ends is to police the education and training of the workforce in the economy and in the educational market-place. This is all carried in the spirit of the 'essential modernisation' of British capitalism.     

Categorising computer science education research

The interdisciplinary nature of Computer Science Education as a field of study is a complicating factor when authors are choosing appropriate journals and conferences for publishing research results. This paper reports a survey of 42 such publications in order to identify the types of paper frequently accepted for publication in each. We review existing taxonomies developed for the general fields of Computer Science and Education, and from this starting point, we develop a novel faceted taxonomy, specifically aimed to help new researchers in the field understand what types of papers are published and where they appear. Our results confirm previous studies indicating the predominance of practice-based, technology-driven reports. We also observe certain differences in educational themes between those found in publications grounded in the Computer Science Education corpus and those emerging from more general Higher Education literature.     

Psychological support for sport coaches: an exploration of practitioner psychologist perspectives

In the present study we add to the literature by exploring the degree to which UK practitioner psychologists perceive themselves able to support sport coaches, and how professional training prepares psychologists for coach work across performance domains. Ten participants comprising seven sport and exercise psychologists with Health Care Professions Council (HCPC) practitioner psychologist status and three trainee psychologists studying towards the British Psychological Society (BPS) qualification in sport and exercise psychology (QSEP) were individually interviewed. All participants reported prior experience of working with coaches across all performance domains. We explored: practitioner’s understanding of the challenges coaches face within their job; practitioner’s experiences of coach work; perspectives about the ways in which practitioners could and should support coaches; and, the degree to which professional training prepares practitioners for coach work. Using recommended procedures of Connelly and Peltzer, content analysis revealed practitioners perceived the challenges faced by coaches are different at grassroots level compared to those working with elite athletes, and that practitioners require skills to provide one-to-one coach support and group-based interventions. All practitioners perceived that training programmes do not adequately equip trainees with skills required for coach work. We discuss the implications for enhancing practitioner training in the UK.     

Reproducibility of the maximum accumulated oxygen deficit and run time to exhaustion during short-distance running

The aim of this study was to determine the reproducibility of the maximal accumulated oxygen deficit and the associated exercise time to exhaustion during short-distance running. Fifteen well-trained males (mean - s : VO 2max = 58.0 - 4.6 ml.kg -1 .min -1 ) performed the maximum accumulated oxygen deficit test at an exercise intensity equivalent to 125% VO 2max . The test was repeated at the same time of day on three occasions within 3 weeks. There was no significant systematic bias between trials for either maximum accumulated oxygen deficit (mean - s : trial 1 = 69.0 - 13.1; trial 2 = 71.4 - 12.5; trial 3 = 70.4 - 15.0 ml O 2 Eq.kg -1 ; ANOVA, F = 0.70, P = 0.51) or exercise time to exhaustion (trial 1 = 194 - 31.1; trial 2 = 198 - 33.2; trial 3 = 201 - 36.8 s; F = 1.49, P = 0.24). In addition, other traditional measures of reliability were also favourable. These included intraclass correlation coefficients of 0.91 and 0.87, and sample coefficients of variation of 6.8% and 5.0%, for maximum accumulated oxygen deficit and exercise time to exhaustion respectively. However, the '95% limits of agreement' were 0 - 15.1 ml O 2 Eq (1.01 2 / 1 1.26 as a ratio) and 0 - 33.5 s (1.0 2 / 1 1.18 as a ratio) for maximum accumulated oxygen deficit and exercise time to exhaustion respectively. We estimate that the sample sizes required to detect a 10% change in exercise time to exhaustion and maximum accumulated oxygen deficit after a repeated measures experiment are 10 and 20 respectively. Unlike the results of previous maximum accumulated oxygen deficit studies, we conclude that it is not a reliable measure.     

The influence of crank rate on peak oxygen consumption during arm crank ergometry

The aim of this study was to assess the influence of three imposed crank rates on the attainment of peak oxygen consumption ( V O 2peak ) and other physiological responses during incremental arm crank ergometry. Twenty physically active, although non-specifically trained, males volunteered for the study. They completed an exercise protocol using an electrically braked arm ergometer (Lode Angio, Groningen, Netherlands) at crank rates of 60, 70 and 80 rev·min -1 . The order of tests was randomized and they were separated by at least 2 days. Peak V O 2 was significantly higher ( P ? 0.05) at 70 and 80 rev·min -1 than at 60 rev·min -1 . Peak ventilation volume increased as a function of crank rate and was higher ( P ? 0.05) at 80 than at 60 rev·min -1 . Peak heart rate was higher ( P ? 0.05) at 70 and 80 rev·min -1 than at 60 rev·min -1 . Furthermore, 70 and 80 rev·min -1 resulted in an extended test time compared with 60 rev·min -1 . The greater physiological responses observed during the tests at the two faster crank rates might have been the result of a postponement of acute localized neuromuscular fatigue, allowing for more work to be completed. We recommend, therefore, that an imposed crank rate between 70 and 80 rev·min -1 should be used to elicit V O 2peak and other physiological responses in arm crank ergometry.     

Confirmatory factor analysis of the Test of Performance Strategies (TOPS) among adolescent athletes

The aim of the present study was to examine the factorial validity of the Test of Performance Strategies (TOPS; Thomas et al., ) among adolescent athletes using confirmatory factor analysis. The TOPS was designed to assess eight psychological strategies used in competition (i.e. activation, automaticity, emotional control, goal-setting, imagery, negative thinking, relaxation and self-talk,) and eight used in practice (the same strategies except negative thinking is replaced by attentional control). National-level athletes (n?=?584) completed the 64-item TOPS during training camps. Fit indices provided partial support for the overall measurement model for the competition items (robust comparative fit index?=?0.92, Tucker-Lewis index?=?0.88, root mean square error of approximation?=?0.05) but minimal support for the training items (robust comparative fit index?=?0.86, Tucker-Lewis index?=?0.81, root mean square error of approximation?=?0.06). For the competition items, the automaticity, goal-setting, relaxation and self-talk scales showed good fit, whereas the activation, emotional control, imagery and negative thinking scales did not. For the practice items, the attentional control, emotional control, goal-setting, imagery and self-talk scales showed good fit, whereas the activation, automaticity and relaxation scales did not. Overall, it appears that the factorial validity of the TOPS for use with adolescents is questionable at present and further development is required.
