Variation in Valuation: How Research Groups Accumulate Credibility in Four Epistemic Cultures

Minerva - This paper aims to explore disciplinary variation in valuation practices by comparing the way research groups accumulate credibility across four epistemic cultures. Our analysis is based...     

Validity and reliability of a linear positional transducer across commonly practised resistance training exercises

This study investigated the validity and reliability of the GymAware PowerTool (GPT). Thirteen resistance trained participants completed three visits, consisting of three repetitions of free-weight back squat, bench press, deadlift (80% one repetition maximum), and countermovement jump. Bar displacement, peak and mean velocity, peak and mean force, and jump height were calculated using the GPT, a three-dimensional motion capture system (Motion Analysis Corporation; 150 Hz), and a force plate (Kistler; 1500 Hz). Least products regression were used to compare agreeability between devices. A within-trial one-way ANOVA, typical error (TE; %), and smallest worthwhile change (SWC) were used to assess reliability. Regression analysis resulted in R² values of >0.85 for all variables excluding deadlift mean velocity (R² = 0.54–0.69). Significant differences were observed between visits 3-2 for bench press bar displacement (0.395 ± 0.055 m; 0.383 ± 0.053 m), and deadlift bar displacement (0.557 ± 0.034 m; 0.568 ± 0.034 m). No other significant differences were found. Low to moderate TE (0.6–8.8%) were found for all variables, with SWC ranging 1.7–7.4%. The data provides evidence that the GPT can be used to measure kinetic and kinematic outputs, however, care should be taken when monitoring deadlift performance.     

The role of the teacher with substance-abusing adolescents in secondary schools

Before choosing to become involved with students who currently are abusing psychoactive substances, teachers must consider not only the potential consequences and payoffs to them professionally, but also what specifically they can do to help adolescents. This article presents some of the philosophical problems, and suggests potential solutions of how to relate to students who engage in potentially self-destructive, drug-related behavior. There is a need for teachers to become quasi-counselors and consultants, since they are the first line of defense against substance use and abuse.     

Cross-cultural training,expatriate self-efficacy,and adjustments to overseas assignments: An empirical investigation of managers in Asia

This paper presents the findings of an empirical study that investigated the relationship between cross-cultural training (CCT) effectiveness, self-efficacy, and adjustment of expatriate managers in Asia. Responses of 169 managers from four different national backgrounds, all currently on overseas assignments in Asia, indicate that the relationship between CCT effectiveness and adjustment is mediated by an increase in self-efficacy. Implications of the findings for professional practice and for future research are discussed.     

Was macht den Sport zum Mediensport?

The popularity of sports varies to different extents around the world and leads to the question: what is a media sport? This contribution discusses definitional principles with the goal of using a model to establish the basis of categorization for future empirical analysis of diverse sports types. Media sports are defined as characteristic of movement structures in the culturally differentiated media sports complex. Features of media sports are distinguished according to the dimensions of context, organization, and (interactive) structure. It becomes clear that media sports types are not only characterized by cultural grounding, success, and charismatic stars, but can also exhibit structural distinctions. In conclusion, real, media-driven, and medial media sports are differentiated to demonstrate application of the model.
