This account of practice shares insights from past and present members of a self-facilitating action learning set, where each of the members is an action learning facilitator. Motivations for joining the set encompassed the opportunity to ‘practice what you preach’ by being a set member as well as a facilitator, the potential to refine and develop facilitation practices in a safe environment and space for personal development. 相似文献

Why do volunteers choose to contribute thousands of unpaid hours per week to Australian archives? This paper presents the results of a nationwide web survey that provides insight into the demographics, motivations and experiences of volunteers in Australian archives. The findings provide a representative overview of formal volunteers in Australian archives, determining ‘who’ they are, the value of the contributions they provide and the level of training and support offered to them. This study is a continuation of existing discussions about volunteers in Australian archives and represents an opportunity for the development of stronger relationships with Australian archival volunteers and, through them, the communities our archives serve. 相似文献

ABSTRACTZoos and aquariums are popular visitor destinations, with around 30 million visits made to them annually throughout the UK and Ireland. The role and mission of modern zoos have evolved, with the conservation of world’s remaining biodiversity now being their major purpose. They seek to aid biodiversity through a combination of public education, in situ and ex situ conservation programmes, and applied scientific research. Directly relevant to this paper, they are also institutions that actively recruit, attract and utilise volunteers. However, the impacts of volunteering in zoos and aquariums, on the volunteers themselves, are under-researched. Here we show that, in a survey of more than 500 volunteers at 19 different zoological collections in the UK, zoo volunteers report positive impacts, specifically in relation to increases in their human and social capital. We also found that these benefits were more pronounced in younger volunteers, and with those volunteers who received more initial training. We conclude that while volunteering in UK zoos correlates with significant personal benefits to individuals, zoos could aim higher and should seek to do more to maximise the positive effects of connecting volunteers with the wildlife and nature found in zoo settings, as well as tailoring their volunteer training programmes for different age groups. 相似文献

The aim of the present study was to evaluate the effects of a 12-week home-based strength, explosive and plyometric (SEP) training on the cost of running (Cr) in well-trained ultra-marathoners and to assess the main mechanical parameters affecting changes in Cr. Twenty-five male runners (38.2?±?7.1 years; body mass index: 23.0?±?1.1?kg·m?2; V˙O2max: 55.4?±?4.0 mlO2·kg?1·min?1) were divided into an exercise (EG?=?13) and control group (CG?=?12). Before and after a 12-week SEP training, Cr, spring-mass model parameters at four speeds (8, 10, 12, 14?km·h?1) were calculated and maximal muscle power (MMP) of the lower limbs was measured. In EG, Cr decreased significantly (p?<?.05) at all tested running speeds (?6.4?±?6.5% at 8?km·h?1; ?3.5?±?5.3% at 10?km·h?1; ?4.0?±?5.5% at 12?km·h?1; ?3.2?±?4.5% at 14?km·h?1), contact time (tc) increased at 8, 10 and 12?km·h?1 by mean +4.4?±?0.1% and ta decreased by ?25.6?±?0.1% at 8?km·h?1 (p?<?.05). Further, inverse relationships between changes in Cr and MMP at 10 (p?=?.013; r?=??0.67) and 12?km·h?1 (p?<?.001; r?=??0.86) were shown. Conversely, no differences were detected in the CG in any of the studied parameters. Thus, 12-week SEP training programme lower the Cr in well-trained ultra-marathoners at submaximal speeds. Increased tc and an inverse relationship between changes in Cr and changes in MMP could be in part explain the decreased Cr. Thus, adding at least three sessions per week of SEP exercises in the normal endurance-training programme may decrease the Cr. 相似文献

In this article, we examine the question of what information is processed during observational learning by evaluating a variety of methods, theories, and empirical data. Initially, we review work involving neuroimaging techniques and infant imitation. We then evaluate data from behavioural experiments involving adults, wherein a variety of attempts have been made to isolate the critical or minimal information constraining the acquisition of coordination. This body of research has included comparisons between video and point-light displays, manipulations to the amount and type of information presented in the display, the collection of point-of-gaze data, and manipulations to the task context in terms of outcome goals. We conclude that observational learning is governed by specific features of the model's action (i.e. motions of the end effector) and the task (i.e. outcome constraints) and, in contrast with traditional theoretical modelling, more global aspects of a model (i.e. the relative motions within and between joints) do not appear to be the primary method for constraining action execution. 相似文献

ABSTRACT We study the developmental and professional activities engaged in by 86 female adult soccer players from the senior national teams of Australia, Canada, England, Sweden, and the United States of America. Players completed the Participation History Questionnaire (PHQ) to elicit the amount and type of activities engaged in across their developmental and professional years, including milestones, soccer-specific activity and engagement in other sport activity. Greater specialisation than diversification characterised their childhood developmental activities, including all players starting in soccer in childhood and accumulating more hours in soccer activity than other sports during this period. However, interindividual variation further characterised these childhood activities, with a proportion of players diversifying into other sports and/or soccer play to a greater or lesser degree during childhood when compared to the other players. The amount of coach-led soccer practice increased for all players across their development culminating in an average of 15–16 h/wk across a 40-week season in early adulthood. In contrast, the amount of engagement in other sports and soccer peer-led play varied between players but generally decreased across adolescence to negligible amounts in late adolescence. Findings are commensurate with the deliberate practice framework and early engagement. 相似文献
