Using discriminant analysis to predict faculty rank

Past attempts to predict the salary of faculty have been flawed by the use of rank, a potential source of bias, but removing rank from the equation seriously reduces prediction. This research studies the degree of bias in rank. Discriminant analysis produced a solution that correctly predicted rank 69% of the time for the 1083 faculty members used in the study. Among teaching and research faculty, there was a significant relationship between the direction of prediction error and gender. For women, the number of times they were predicted to have a rank higher than their actual rank exceeded the opposite condition by 2 1/2 times; for men, there was a slight tendency for the opposite. Methods were suggested for using the information administratively to correct problems. Further, recommendations are made to use the results to study salary-bias problems.     

Preliminary development of a questionnaire to assess peer athlete mentoring functions: the Athlete Mentoring Questionnaire (AMQ)

Using a multiphase approach, the purpose of the present study was to develop a psychometrically sound questionnaire to measure protégés’ perceptions of peer athlete mentoring functions. Phase 1 consisted of three stages: (a) item development, (b) assessment of content validity via think-aloud interviews with peer mentored athletes, and (c) assessment of content validity via an expert rating panel. In phase 2, 377 Canadian National team and varsity athletes who were peer mentored completed an initial 42-item version of the Athlete Mentoring Questionnaire (AMQ) and its factor structure was examined using confirmatory factor analysis (CFA), exploratory structural equation modeling (ESEM), and hierarchical ESEM (ESEM-within-CFA). Measurement invariance testing was also performed in phase 2. The final version of the AMQ contains 34 items that measure six peer athlete mentoring functions. It is hoped that the development of the AMQ will spur research in the emerging area of peer athlete mentoring.     

Sport expertise in perception–action coupling revealed in a visuomotor tracking task

We compared the visuomotor coordination of tennis players with different levels of expertise (Super-Experts, Experts and Non-Experts) in a visuomotor tracking (VMT) task. Participants were asked to track a moving target which could rebound on the sides of a 2D screen. Results indicated that the VMT task allowed the discrimination of expertise. Multiple regression analysis revealed that performance could be explained by the temporal adaptation of participants to rebounds and the number of movement adaptations. Compared to Non-Experts, the Experts had a shorter perturbation time with higher adaptation and regulation. This corresponds to a better perception–action coupling and the predominant use of a prospective control process. Results also indicate that perception–action coupling capacities are transferable to virtual tasks, and allow us to reveal processes of visuomotor coordination that differentiate experts and novices.     

Boot-insole effects on comfort and plantar loading at the heel and fifth metatarsal during running and turning in soccer

Plantar loading may influence comfort, performance and injury risk in soccer boots. This study investigated the effect of cleat configuration and insole cushioning levels on perception of comfort and in-shoe plantar pressures at the heel and fifth metatarsal head region. Nine soccer academy players (age 15.7 ± 1.6 years; height 1.80 ± 0.40 m; body mass 71.9 ± 6.1 kg) took part in the study. Two boot models (8 and 6 cleats) and two insoles (Poron and Poron/gel) provided four footwear combinations assessed using pressure insoles during running and 180° turning. Mechanical and comfort perception tests differentiated boot and insole conditions. During biomechanical testing, the Poron insole generally provided lower peak pressures than the Poron/gel insole, particularly during the braking step of the turn. The boot model did not independently influence peak pressures at the fifth metatarsal, and had minimal influence on heel loads. Specific boot-insole combinations performed differently (P < 0.05). The 8-cleat boot and the Poron insole performed best biomechanically and perceptually, but the combined condition did not. Inclusion of kinematic data and improved control of the turning technique are recommended to strengthen future research. The mechanical, perception and biomechanical results highlight the need for a multi-faceted approach in the assessment of footwear.     

Determining friction and effective loading for sled sprinting

Understanding the impact of friction in sled sprinting allows the quantification of kinetic outputs and the effective loading experienced by the athlete. This study assessed changes in the coefficient of friction (µ_k) of a sled sprint-training device with changing mass and speed to provide a means of quantifying effective loading for athletes. A common sled equipped with a load cell was towed across an athletics track using a motorised winch under variable sled mass (33.1–99.6 kg) with constant speeds (0.1 and 0.3 m · s^?1), and with constant sled mass (55.6 kg) and varying speeds (0.1–6.0 m · s^?1). Mean force data were analysed, with five trials performed for each condition to assess the reliability of measures. Variables were determined as reliable (ICC > 0.99, CV < 4.3%), with normal-force/friction-force and speed/coefficient of friction relationships well fitted with linear (R² = 0.994–0.995) and quadratic regressions (R² = 0.999), respectively (P < 0.001). The linearity of composite friction values determined at two speeds, and the range in values from the quadratic fit (µ_k = 0.35–0.47) suggested µ_k and effective loading were dependent on instantaneous speed on athletics track surfaces. This research provides a proof-of-concept for the assessment of friction characteristics during sled towing, with a practical example of its application in determining effective loading and sled-sprinting kinetics. The results clarify effects of friction during sled sprinting and improve the accuracy of loading applications in practice and transparency of reporting in research.     

The importance of school culture in supporting student mental health in secondary schools. Insights from a qualitative study

Schools have the potential to provide a place of education and sanctuary for children and young people of all backgrounds. The rise in mental health problems in children and young people in the wake of the COVID-19 pandemic, particularly in relation to growing inequities, means that identifying ways in which schools can help respond to this growing mental health crisis demands urgent attention. This paper reports on case studies carried out in two London comprehensive schools, exploring how aspects of school culture impact (both positively and negatively) on student mental health. Methods comprised in-depth interviews with school staff and parents, focus groups with students and documentary analysis of relevant materials. Fieldwork was conducted during spring 2021 as schools were returning to face-to-face learning following national periods of lockdown. Our study shows how schools might attempt to drive positive mental health outcomes through aspects of school culture and uses a system framework to explore complexities around cause and effect in this area. Key findings include the considerable differences in school mental health provision, challenges in the identification of student mental health needs and the importance of recognising how the mental health of teachers must be considered alongside that of students. Overall, we highlight particular dilemmas of the post-lockdown era that our findings indicate for the education sector, and suggest there may be value in reframing the apparent conflict between ‘attainment gaps’ and personal development, moving towards an educational approach with greater complementarity of these aims.     

Transgender young people’s narratives of intimacy and sexual health: implications for sexuality education

Abstract

Sexuality education as pedagogy is often fraught by the perceived requirement to balance the informational needs of young people with an investment in notions of childhood ‘innocence’. Nowhere is this perhaps more evident than in sexuality education that seeks to be inclusive of transgender young people, often resulting in the failure of such education to address the needs of such students. In an attempt at addressing the relative dearth of information about what transgender young people would like to see covered in sexuality education, in this paper we explore transgender young people’s accounts of intimacy and sexual health and consider what this means for school-based sexuality education. To do this, we analyse discussions of intimacy from the perspectives of transgender young people as narrated in a sample of YouTube videos. We conclude by advocating for an approach to sexuality education that largely eschews the gendering of body parts and gametes, and which instead focuses on function, so as to not only address the needs of transgender young people (who may find normative discussions of genitals distressing), but to also provide cisgender young people with a more inclusive understanding of their own and other people’s bodies and desires.
