Mentoring: A Typology of Costs for Higher Education Faculty

In this theoretical paper, we apply a social exchange framework to understand mentors’ negative experiences. We propose a typology of costs, categorized according to psychosocial and career mentoring functions. Our typology generates testable research propositions. Psychosocial costs of mentoring are burnout, anger, and grief or loss. Career costs of mentoring include diminished reputation, decrease in productivity, and risk of ethical transgressions. The typology focuses on faculty in higher education because of the prevalence and importance of mentoring in that work setting. However, the typology may be extended to career arenas such as law, medicine, and the military. The theory presents a framework for acknowledging negative experiences and the costs associated with mentorship.     

Knowledge management in a small knowledge intensive organisation: research design process at the Cochrane Child Health Field

At the Cochrane Child Health Field, we embarked on a complex project to develop short one-page clinical summaries of health evidence to answer questions posed by paediatricians. Subsequently, our priority was to test these ‘Clinical Answers’ (CAs) to ensure that our product was meeting their needs. This paper provides a reflection of the process of developing a research design to evaluate the CAs format, particularly focusing on the process of partnership. Schön's concept of reflection-on-action is used as a framework.     

Investigating the impact of at-home learning on secondary school-aged children with ADHD: a qualitative study

Students with ADHD can benefit from at-home learning in terms of managing their symptoms; however, lockdown restrictions due to the pandemic are having negative impacts on the student population. This study was designed to ascertain how students with ADHD have been impacted by at-home learning under lockdown restrictions. An interpretative phenomenological analysis was conducted using semi-structured interviews from students, parents and teaching staff. These interviews were used to identify three main themes (anxiety caused by at-home learning, change in social interaction and academic impact of at-home learning) that best identified the participants' experiences. The results suggested that whilst supportive home environments helped students with ADHD to better manage their symptoms, social anxiety was a significant problem, and not all schools allowed students with ADHD to take full advantage of at-home learning for their students with ADHD.     

The effect of ball-carrying technique and experience on sprinting in rugby union

Abstract

There are several ways of carrying the ball in rugby union, which could influence the speed at which a player can run. We assessed 52 rugby players (34 males, 18 females) during a maximum sprint over 30 m without the ball, with the ball under one arm, and with the ball in both hands. Timing gates were used to measure time over the initial 10 m and the last 20 m. It has previously been reported (Grant et al., 2003 Grant, S. J., Oommen, G., McColl, G., Taylor, J., Watkins, L.Friel, N. 2003. The effects of ball carrying method on sprint speed in rugby union football players. Journal of Sports Sciences, 21: 1009–1015. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) that running with the ball produces a slower sprinting speed than running without the ball. We hypothesized that the decrease in speed caused by carrying the ball would become less marked with the experience of the player. The male and female players were each divided into two groups: a “beginner” group that consisted of players in their first or second season and an “experienced” group that was composed of players who had played for more than two seasons. A 2 × 3 mixed-model analysis of variance was used to identify differences (P < 0.01) between the beginner and experienced groups in the three sprinting conditions. The times for the males for the first 10 m sprints without the ball, with the ball under one arm, and with the ball in both hands were 1.87 ± 0.08 s, 1.87 ± 0.08 s, and 1.91 ± 0.1 s for the beginners, and 1.87 ± 0.1, 1.88 ± 0.1 and 1.88 ± 0.12 for the more experienced players respectively. The times for the females for the first 10 m without the ball, with the ball under one arm, and with the ball in both hands were 2.13 ± 0.16 s, 2.19 ± 0.17 s, and 2.20 ± 0.16 s for the beginners, and 2.03 ± 0.12 s, 2.03 ± 0.09 s, and 2.04 ± 0.1 s for the more experienced players respectively. For the last 20 m of the 30-m sprint, there were differences between the different sprint conditions (P < 0.001) but no differences that were attributable to experience (P = 0.297). The times for the males over the last 20 m without the ball, with the ball under one arm, and with the ball in both hands were 2.58 ± 0.19 s, 2.61 ± 0.12 s, and 2.65 ± 0.12 s for the beginners, and 2.59 ± 0.12, 2.62 ± 0.23, and 2.65 ± 0.18 s for the more experienced players respectively. The times for the females over the last 20 m without the ball, with the ball under one arm, and with the ball in both hands were 3.25 ± 0.38 s, 3.35 ± 0.42 s, and 3.40 ± 0.46 s for the beginners, and 3.04 ± 0.32 s, 3.06 ± 0.22 s, and 3.13 ± 0.27 s for the more experienced players respectively. No gender-specific differences were detected. The results of this study suggest that practising sprints while carrying a ball benefits the early phase of sprinting while carrying the ball.

Effects of different intensities of resistance training with equated volume load on muscle strength and hypertrophy

The present study investigated the effects of different intensities of resistance training (RT) on elbow flexion and leg press one-repetition maximum (1RM) and muscle cross-sectional area (CSA). Thirty men volunteered to participate in an RT programme, performed twice a week for 12 weeks. The study employed a within-subject design, in which one leg and arm trained at 20% 1RM (G20) and the contralateral limb was randomly assigned to one of the three conditions: 40% (G40); 60% (G60), and 80% 1RM (G80). The G20 started RT session with three sets to failure. After G20 training, the number of sets was adjusted for the other contralateral limb conditions with volume-matched. CSA and 1RM were assessed at pre, post-6 weeks, and post-12 weeks. There was time effect for CSA for the vastus lateralis (VL) (8.9%, 20.5%, 20.4%, and 19.5%) and elbow flexors (EF) (11.4%, 25.3%, 25.1%, and 25%) in G20, G40, G60, and G80, respectively (p?>?.05). G80 showed higher CSA than G20 for VL (19.5% vs. 8.9%) and EF (25% vs. 11.4%) at post-12 weeks (p?p?相似文献
