Enabling critical reflection on research supervisory practice

This paper describes the development of an instrument—The Reflective Supervisor Questionnaire (RSQ). The RSQ maps the domain of research supervisory practice as a facilitative process involving educational tasks and activities. It is designed to assist research supervisors explore, by means of self‐reflection and reflection on feedback from others, how they practise supervision. In developing the RSQ 58 items were generated describing 5 hypothesised constructs derived from prior research. The resulting instrument was tested on postgraduate research students in 2 institutions. The questionnaire correlated highly with an established questionnaire supervision scale and with an overall satisfaction measure. Four factors identified in an exploratory analysis closely approximated the hypothesised constructs and extended the theoretical framework being developed. These 4 factors identified 4 subsets of facilitative supervisory practice: Progressing the Candidature, Mentoring, Coaching the Research Project, and Sponsoring Student Participation in Academic/Professional Practice. Issues in the interpretation of the findings and the possible usage in academic development programs of an instrument based on them are discussed.     

Age Differences in Media Multitasking: A Diary Study

This study provides insight in age differences in the amount of media multitasking and in the media that people combine. Results of a diary study (N = 3,048) among 13- to 65-year-olds reject the popular notion that media multitasking is particularly prevalent among young people. The youngest (13–16 years) and the oldest (50–65 years) age groups did distinguish themselves in terms of media combinations. The youngest group particularly combined music with online activities, whereas the oldest group was unique in combining radio with e-mail or newspapers. A plausible explanation for these age differences in media multitasking are lifespan related and generational differences in media use in general.     

Detailed description of Division I ice hockey concussions: Findings from the NCAA and Department of Defense CARE Consortium

Objective:Since concussion is the most common injury in ice hockey,the objective of the current study was to elucidate risk factors,specific mechanisms,and clinical presentations of concussion in men’s and women’s ice hockey.Methods:Ice hockey players from 5 institutions participating in the Concussion Assessment,Research,and Education Consortium were eligible for the current study.Participants who sustained a concussion outside of this sport were excluded.There were 332(250 males,82 females)athletes who participated in ice hockey,and 47(36 males,11 females)who sustained a concussion.Results:Previous concussion(odds ratio(OR)=2.00;95%confidence interval(95%CI):1.02‒3.91)was associated with increased incident concussion odds,while wearing a mouthguard was protective against incident concussion(OR=0.43;95%CI:0.22‒0.85).Overall,concussion mechanisms did not significantly differ between sexes.There were specific differences in how concussions presented clinically across male and female ice hockey players,however.Females(9.09%)were less likely than males(41.67%)to have a delayed symptom onset(p=0.045).Additionally,females took significantly longer to reach asymptomatic(p=0.015)and return-to-play clearance(p=0.005).Within the first 2 weeks post-concussion,86.11%of males reached asymptomatic,while only 45.50%of females reached the same phase of recovery.Most males(91.67%)were cleared for return to play within 3 weeks of their concussion,compared to less than half(45.50%)of females.Conclusion:The current study proposes possible risk factors,mechanisms,and clinical profiles to be validated in future concussions studies with larger female sample sizes.Understanding specific risk factors,concussion mechanisms,and clinical profiles of concussion in collegiate ice hockey may generate ideas for future concussion prevention or intervention studies.     

Strengthening collaborative capacity: experiences from a short,intensive field course on ecosystems,health and society

A key capacity for engagement in the emerging field of ecohealth is the ability to work collaboratively. Between 2008 and 2010, the Canadian Community of Practice in Ecosystem Approaches to Health collectively designed and delivered three foundational, intensive, field courses. This paper presents findings derived from both quantitative and qualitative student course evaluation survey data. New insights arise around: the diverse opportunities for learning collaboratively in order to tackle complex socio-ecological issues, the social dynamics of collaborative relationships and learning, and the learning challenges that arise during intensive field courses. The lessons learned from these foundational years have enhanced understanding of the interrelated contributions to collaborative learning and relationship building and their relevance to addressing issues spanning ecosystems, health and society.     

Growth and diversity in doctoral education: assessing the Australian experience

The major growth of doctoral education in recent decades has attracted attention from policy makers and researchers. In this article we explore the growth of doctoral education in Australia, its impact on diversity in respect of the doctoral population, shifts in disciplinary strengths, institutional concentration and award programs. We conclude that there has been both change and continuity in the provision of doctoral education with extensive variation at the level of practice in what is a reasonably stable system featuring continuing hierarchical institutional diversification. The limitations of available data and issues for further research, policy and practice are discussed.

Isometric quadriceps strength determines sailing performance and neuromuscular fatigue during an upwind sailing emulation

This study investigates the physiological responses to upwind sailing on a laser emulation ergometer and analyses the components of the physical profile that determine the physiological responses related to sailing level. Ten male high-level laser sailors performed an upwind sailing test, incremental cycling test and quadriceps strength test. During the upwind sailing test, heart rate (HR), oxygen uptake, ventilation, respiratory exchange ratio, rating of perceived exertion (RPE) and lactate concentration were measured, combined with near-infrared spectroscopy (NIRS) and electromyography (EMG) registration of the M. Vastus lateralis. Repeated measures ANOVA showed for the cardio-respiratory, metabolic and muscles responses (mean power frequency [MPF], root mean square [RMS], deoxy[Hb+Mb]) during the upwind sailing test an initial significant increase followed by a stabilisation, despite a constant increase in RPE. Stepwise regression analysis showed that better sailing level was for 46.5% predicted by lower MPF decrease. Lower MPF decrease was for 57.8% predicted by a higher maximal isometric quadriceps strength. In conclusion, this study indicates that higher sailing level was mainly determined by a lower rate of neuromuscular fatigue during the upwind sailing test (as indicated by MPF decrease). Additionally, the level of neuromuscular fatigue was mainly determined by higher maximal isometric quadriceps strength stressing the importance of resistance training in the planning of training.
