A Moment of Letting Go: Iris Murdoch and the Morally Transformative Process of Unselfing

Higher education as a personal, intellectual and moral cultivation is a longstanding ideal that is constantly challenged by the view that education is merely the development of specific skills for vocational and personal success. Much research argues that the latter understanding makes education a technical affair that creates an egocentric emphasis on the individual students’ ambitions and desires. This article joins in the defence of the former ideal by enquiring into the moral dimensions of education. This is done by turning to Iris Murdoch's idea of moral transformation, with a specific focus on the idea of unselfing. The main argument is that unselfing is a transformative process characterised by a growing attunement to the surrounding world, and the interconnectedness of goal and process is emphasised. Also, to gain a deeper understanding of what unselfing entails I turn to the idea of attention. It is understood as having a specific direction, outward from the egocentric, and as enabling unselfing. The article concludes by suggesting that unselfing can offer a challenge to (higher) education as it entails a moment of letting go of plans and narratives, and of surrendering to the influence of an existence that exceeds the individual. This moment is of relevance to education as it is crucial to the possibility of growing as a moral being as it cultivates a moral manner of relating to others.     

Body composition differences by age and playing standard in male rugby union and rugby league: A systematic review and meta-analysis

ABSTRACT

This systematic review and meta-analysis aimed to determine differences in body compositionn between playing standard and age in male rugby union and rugby league athletes. The MOOSE (Meta-analysis of Observational Studies in Epidemiology) guidelines for design, implementation, and reporting were followed. Studies were required to be in male rugby union or league and have body composition as the primary or secondary outcome. Data was required to be presented separately for positional groups and body composition presented as whole-body. A systematic search was performed in PubMed, Cochrane Library, MEDLINE, SPORTDiscus, and CINHAHL via EBSCOhost. 57 studies were included for meta-analysis. Results highlighted significantly higher fat-free mass in senior elite than senior sub-elite or junior elite athletes for all RU and RL forwards. Small and non-significant differences were found in fat mass between rugby union playing standards and age categories. Rugby league senior elite forwards had less fat mass than junior elite forwards. Practitioners should prioritise training and nutritional strategies that maximise fat-free mass development, especially in junior elite cohorts.     

Cognitive behavioural strategies and anxiety in elite orienteers

The primary purpose of this exploratory field study was to examine the use of cognitive behavioural strategies by highly skilled orienteers prior to and during competition. A secondary purpose of the study was to investigate whether differences in the level of qualification in orienteering is related to state anxiety. The subjects were divided into three classes with respect to their international and national records. The first two classes (A and B) were composed of international and national level athletes. The third class (C) included orienteers with unknown international records. Examination of the use of behavioural cognitive strategies during competition indicated that all orienteers reported a moderate use of mental imagery, above moderate use of inner talk and a focus of attention on present action rather than past or future. The other major findings were that prior to competition, superior orienteers reported use of higher self‐efficacy, more positive outcome expectations and more task demand orientation than their less successful counterparts. Top orienteers coped more successfully with pre‐competition anxiety by lowering their anxiety to a more moderate level prior to the actual performance.     

Dynamics of the martial arts high front kick

Fast unloaded movements (i.e. striking, throwing and kicking) are typically performed in a proximo‐distal sequence, where initially high proximal segments accelerate while distal segments lag behind, after which proximal segments decelerate while distal segments accelerate. The aims of this study were to examine whether proximal segment deceleration is performed actively by antagonist muscles or is a passive consequence of distal segment movement, and whether distal segment acceleration is enhanced by proximal segment deceleration. Seventeen skilled taekwon‐do practitioners were filmed using a high‐speed camera while performing a high front kick. During kicking, EMG recordings were obtained from five major lower extremity muscles. Based on the kinematic data, inverse dynamics computations were performed yielding muscle moments and motion‐dependent moments. The results indicated that thigh deceleration was caused by motion‐dependent moments arising from lower leg motion and not by active deceleration. This was supported by the EMG recordings. Lower leg acceleration was caused partly by a knee extensor muscle moment and partly by a motion‐dependent moment arising from thigh angular velocity. Thus, lower leg acceleration was not enhanced by thigh deceleration. On the contrary, thigh deceleration, although not desirable, is unavoidable because of lower leg acceleration.     

The policy problem: the National Disability Insurance Scheme (NDIS) and implications for access to education

This paper explores the changing terrain of disability support policy in Australia. Drawing on a critical disability framework of policy sociology, the paper considers the policy problem of access to education for people with disabilities under recent reform by means of the National Disability Insurance Scheme (NDIS), which commenced full roll-out across the country from July 2016. The paper reviews NDIS reports, legislation and associated literature to consider how eligibility to scheme participation and education services are shaped, and how education is positioned in the development and implementation of the NDIS. The analysis highlights tensions that exist for people with disabilities and their families who both access the scheme and who might draw on its provision to support their education, because of the way the policy is oriented towards pathological categorisation, standardised outcomes and service delineation rather than integrated support and informed involvement. The paper concludes by arguing that despite the policy priority across Organisation for Economic Co-operation and Development countries of increasing lifelong learning opportunities, fragmented NDIS policy in Australia prevents people with disabilities from achieving this ideal.
