Short-term reliability of inflammatory mediators and response to exercise in the heat

Prospective application of serum cytokines, lipopolysaccharide (LPS), and heat shock proteins (eHSPs) requires reliable measurement of these biomarkers that can signify exercise-induced heat stress in hot conditions. To accomplish this, both short-term (7 day) reliability (at rest, n = 12) and the acute responsiveness of each biomarker to exercise in the heat (pre and post 60-min cycling, 34.5°C and 70% RH, n = 20) were evaluated. Serum was analysed for the concentration of C-reactive protein (CRP), interleukin-6 (IL-6), heat shock protein 72 (eHSP72), immunoglobulin M (IgM) and LPS. Test–retest reliability was determined as the coefficient of variation (CV). Biomarkers with the least short-term within-participant variation were IL-6 (19%, ±20%; CV, ±95% confidence limits (CL)) and LPS (23%, ±13%). Greater variability was observed for IgM, eHSP72 and CRP (CV range 28–38%). IL-6 exhibited the largest increase in response to acute exercise (95%, ±11%, P = < 0.001) and although CRP had a modest CV (12%, ±7%), it increased substantially post-exercise (P = 0.02, ES; 0.78). In contrast, eHSP72 and LPS exhibited trivial changes post-exercise. It appears variation of common inflammatory markers after exercise in the heat is not always discernible from short-term (weekly) variation.     

'Accreditation' of engineering studies: Formal systems versus individual responsibility

The globalization of the world's economy (and its labour market) reveals a growing need for graduate mobility. In this free global market, educational institutions are under increased pressure to show their intrinsic value, to define and guarantee their quality and to show continually their relevance to their communities and national governments (often the main financial stakeholder). Accreditation of degrees (and institutions) by a recognized international authority (or by an international network of recognized national authorities) is often quoted as the solution to address the needs of mobility and quality assurance. I believe that the process of accreditation is not the fundamental answer to these needs. Accreditation in education can be a stabilizing factor in a small-scale economical system, but it fails on a large (global) scale. The reason for this is that any accreditation scheme judges quality in an arbitrary way. The key to opening up free mobility of competencies and to leveraging quality education is to develop a system to measure objectively an individual's competence. A system that makes the abstract notion of 'competence' tangible to anyone, but that leaves the judgement open to the ones who need to judge…     

Play to win! Using games in library instruction to enhance student learning

Research has shown that educational games can have positive impacts on student learning and motivation. The success of a game played in a library instruction class depends on the type of game selected, the development of learning outcomes, and the flexibility of the librarian during class. This article explains the benefits to students and librarians of using games, discusses the development and use of a Jeopardy-style game, and provides practical tips for librarians interested in developing and incorporating games into one-time library instruction sessions.     

Validation of two accelerometers to determine mechanical loading of physical activities in children

The purpose of this study was to assess the validity of accelerometers using force plates (i.e., ground reaction force (GRF)) during the performance of different tasks of daily physical activity in children. Thirteen children (10.1 (range 5.4–15.7) years, 3 girls) wore two accelerometers (ActiGraph GT3X+ (ACT), GENEA (GEN)) at the hip that provide raw acceleration signals at 100 Hz. Participants completed different tasks (walking, jogging, running, landings from boxes of different height, rope skipping, dancing) on a force plate. GRF was collected for one step per trial (10 trials) for ambulatory movements and for all landings (10 trials), rope skips and dance procedures. Accelerometer outputs as peak loading (g) per activity were averaged. ANOVA, correlation analyses and Bland–Altman plots were computed to determine validity of accelerometers using GRF. There was a main effect of task with increasing acceleration values in tasks with increasing locomotion speed and landing height (P < 0.001). Data from ACT and GEN correlated with GRF (r = 0.90 and 0.89, respectively) and between each other (r = 0.98), but both accelerometers consistently overestimated GRF. The new generation of accelerometer models that allow raw signal detection are reasonably accurate to measure impact loading of bone in children, although they systematically overestimate GRF.     

Code-switching 101: Black women counselor educators’ personal and professional identity development

The perceptions of personal and professional identity development from four Black women counselor educators were examined through a collaborative autoethnography methodology. Themes identified include (a) intentionality of code-switching, (b) inextricable identities, (c) fight for and with authenticity, and (d) mutual development of personal and professional identities.     

Hooligans,Casuals, Independents: Decivilisation or Rationalisation of the Activity?

If there is one phenomenon which highlights the lack of role distance of certain sport actors, it is obviously hooliganism. In the mid-1980s, Norbert Elias and Eric Dunning became interested in the role played by modern sports in the ‘civilising process’ and, analysing the violence of sport crowds, introduced a culturalist interpretation of the actions. They were considered to be the work of members of the ‘rough working class’, who were less advanced in the ‘civilising process’ and had still not achieved sufficient self-control. In these groups, characterised by social functioning in the form of a segmentary bond, violence was thought to be a traditional way of resolving conflicts, a significant aspect and essential part of their ethos. This is an over-determined interpretation of the violence of sports crowds which naturalises and socialises this violence. This vision poses a problem, that of the negation of any logic on the part of the actors involved. This viewpoint leads us to consider violence as a social product and a ‘practical accomplishment’, the result of the way in which supporters interpret and live in the world that surrounds them, and, as such, it is the individual and collective motives and purposes that should be investigated.     

Growing Pains: The Dearing Report from a European Perspective

The United Kingdom, like most of its European partners has achieved 'mass' higher education and Dearing has tried to come to terms with the implications of this and move the debate a stage forward from mass higher education to the learning society, embracing a much wider range of clients and forms of post school education and training. The responsibilities of individual students to manage their own learning experiences are much nearer the centre of the picture than has hitherto been normal in UK universities and colleges. There are similarities between the proposed qualification structure with stopping off points at the end of each full time year and the arrangements which have been in operation in France for some years. There are other examples of proposed convergence with continental models, not least the increase in class size and the assimilation into higher education of casual lecturers.
In contrast the paper also draws attention to the growing role of the state (disguised as the nation) in higher education and the associated 'juridification' which seems to be on the wane in Europe. Britain seems well set to discover that feature once decried as quintessential of the overmighty European State, namely the avalanche of ministerial circulars and decrees which ensured cohesion and compliance but also imposed heavy burdens on university managers.
