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.     

Exposing athletes to playing form activity: outcomes of a randomised control trial among community netball teams using a game-centred approach

This study evaluated whether exposing junior netball players to greater amounts of competition relevant activity (playing form activity) had an effect on game play outcomes and session involvement. A group-randomised controlled trial in one junior netball club in the Hunter Region, NSW, Australia. Ninety female athletes (mean age = 9.04 years, SD 1.53) were randomised by team (n = 11) into the intervention (n = 41) or 9-week wait-list control (n = 49) condition. The Professional Learning for Understanding Games Education into Sport (PLUNGE into Sport) programme was undertaken in the first half of nine training sessions (9 × 30 min). The intervention exposed athletes to playing form activity through a coach development programme within training sessions. Athletes’ decision-making, support and skill outcomes during a small-sided invasion game, and session involvement (pedometer step/min), were measured at baseline and 9-week follow-up. Linear mixed models revealed significant group-by-time intervention effects (P < 0.05) for decision-making (d = 0.4) and support (d = 0.5) during game play, and in-session activity (d = 1.2). An intervention exposing athletes to greater levels of playing form activity, delivered via a coach education programme, was efficacious in improving athlete decision-making and support skills in game play and increasing athlete involvement during sessions.     

A new role for the school psychologists— who needs it?

Educators are expressing concern over the wide and growing gap which they perceive to exist between research and practice in our nation's schools. A review of the literature reveals that this important, long-standing concern is well founded. It is proposed that the school psychologist with his/her specialized training in research theory and methodology and unique role as a practitioner in the school setting is the ideal professional to effect a linking of formal knowledge to educational practice. Presumably, the provision of such a vitally needed function will serve to enhance school psychologists' often less than favorable image with their educator colleagues. A paradigm is offered for effecting research into practice utilizing the school psychologist in the role of knowledge-linker.     

Knee extensor and flexor torque development with concentric and eccentric isokinetic training

This study assessed muscular torque and rate of torque development following concentric (CON) or eccentric (ECC) isokinetic training. Thirty-eight women were randomly assigned to either CON or ECC training groups. Training consisted of knee extension and flexion of the nondominant leg three times per week for 20 weeks (SD = 1). Eccentric training increased ECC knee extension and flexion peak torque more than CON training. The ECC group improved acceleration time and time to peak torque with ECC movements versus the CON group. Slow-velocity ECC isokinetic training yielded greater ECC and similar CON torque development gains versus CON training over the course of 20 weeks in young women.     

Congruence between educational attitudes and academic philosophies

Kerlinger's theory of social attitudes asserts that attitudes toward educational practices can be represented by the independent dimensions of progres-sivism and traditionalism. This study focused on the relationship between these attitudes and the philosophies of realism and pragmatism. A sample of 152 graduate students in education completed three instruments measuring educational attitudes and the basic and applied philosophies. Factor analytic results supported a dualistic theory rather than a bipolar theory for attitudes and philosophies. Pragmatists supported the progressive referents of children's interests and social development as educational goals, while realistsy supported traditional concepts emphasizing structure and the learning of content. The results are discussed in terms of the consistency between educational attitudes and a teacher's philosophy.     

The Library as Service-Learning Partner: A Win–Win Collaboration with Students and Faculty

ABSTRACT

This case study of a quarter-long collaborative service-learning project, repeated over several quarters, involves technical communication students and librarians at Eastern Washington University. The librarians needed to promote RefWorks, while the technical communication faculty needed a client with a computer-based tool for students to learn and then teach to others. Working in teams, fifty-eight students planned and executed fifteen RefWorks workshops for students. The majority of students liked using RefWorks and gave successful presentations to their peers. This project increased awareness and usage of RefWorks while also affording librarians a student-centered perspective on teaching and using this tool. In this win–win collaboration, students learned useful skills in addition to developing a sense of community with the library.
