Of all periods in the history of British tennis, arguably the inter-war years were the most significant and tumultuous. Officials recommenced activities with an ultimate goal of restoring British prowess at an international level. This paper aims to assess the long-term effectiveness of the LTA’s efforts in these regards. It was far from straightforward. After several years of lacklustre performances, a group of reformers staged a mutiny that culminated at the turbulent 1922 AGM, where they unseated several incumbent councillors. Yet they failed to shift significantly the balance of power away from the ageing establishment figures they had targeted. Nevertheless, a period of self-reflection followed, and the partially reformed LTA responded by refocusing its efforts on two key areas: the development of coaching-professionals and of tennis in the public schools. However, it was evident that deep-rooted antipathy towards the promotion of a more modern, American-inspired, performance-oriented, 'professional' mentality among players, and fears over the concomitant erosion of amateurism, underpinned the LTA’s reluctance to increase access and develop talent among those outside of the upper-middle class. Fred Perry’s exploits offered a temporary respite from some of the criticism, but ultimately merely proved to mask the LTA’s staunch conservatism during this period. 相似文献

A number of field-based investigations have evidenced practically significant relationships between clubhead velocity (CHV), vertical jump performance and maximum strength. Unfortunately, whilst these investigations provide a great deal of external validity, they are unable to ascertain vertical ground reaction force (vGRF) variables that may relate to golfers’ CHVs. This investigation aimed to assess if the variance in European Challenge Tour golfers’ CHVs could be predicted by countermovement jump (CMJ) positive impulse (PI), isometric mid-thigh pull (IMTP) peak force (PF) and rate of force development (RFD) from 0–50 ms, 0–100 ms, 0–150 ms and 0–200 ms. Thirty-one elite level European Challenge Tour golfers performed a CMJ and IMTP on dual force plates at a tournament venue, with CHV measured on a driving range. Hierarchical multiple regression results indicated that the variance in CHV was significantly predicted by all four models (model one R2 = 0.379; model two R2 = 0.392, model three R2 = 0.422, model four R2 = 0.480), with Akaike’s information criterion indicating that model one was the best fit. Individual standardised beta coefficients revealed that CMJ PI was the only significant variable, accounting for 37.9% of the variance in European Challenge Tour Golfers’ CHVs. 相似文献

ABSTRACTThis paper reflects on approaches to collaborative knowledge exchange projects between UK universities and the creative economy. It develops a preliminary account of cultural ecology as a systematic approach to producing impact in the creative economy. It argues that such an approach is a powerful way to aggregate micro-businesses and small and medium sized enterprises in a meaningful network of new relationships. The paper uses social network analysis software to begin to visualise the pattern of relationships that constitute the ecosystem. The paper reports on the work of the Research and Enterprise for Arts and Creative Technologies Hub, one of four Knowledge Exchange Hubs for the Creative Economy established by the Arts and Humanities Research Council. 相似文献

ABSTRACTThe aims of this study were to analyse the optimal cadence for peak power production and time to peak power in bicycle motocross (BMX) riders. Six male elite BMX riders volunteered for the study. Each rider completed 3 maximal sprints at a cadence of 80, 100, 120 and 140 revs · min?1 on a laboratory Schoberer Rad Messtechnik (SRM) cycle ergometer in isokinetic mode. The riders’ mean values for peak power and time of power production in all 3 tests were recorded. The BMX riders produced peak power (1105 ± 139 W) at 100 revs · min?1 with lower peak power produced at 80 revs · min?1 (1060 ± 69 W, (F(2,15) = 3.162; P = .266; η2 = 0.960), 120 revs · min?1 (1077 ± 141 W, (F(2,15) = 4.348; P = .203; η2 = 0.970) and 140 revs · min?1 (1046 ± 175 W, (F(2,15) = 12.350; P = 0.077; η2 = 0.989). The shortest time to power production was attained at 120 revs · min?1 in 2.5 ± 1.07 s. Whilst a cadence of 80 revs · min?1 (3.5 ± 0.8 s, (F(2,15) = 2.667; P = .284; η2 = 0.800) 100 revs · min?1 (3.00 ± 1.13 s, (F(2,15) = 24.832; P = .039; η2 = 0.974) and 140 revs · min?1 (3.50 ± 0.88 s, (F(2,15) = 44.167; P = .006; η2 = 0.967)) all recorded a longer time to peak power production. The results indicate that the optimal cadence for producing peak power output and reducing the time to peak power output are attained at comparatively low cadences for sprint cycling events. These findings could potentially inform strength and conditioning training to maximise dynamic force production and enable coaches to select optimal gear ratios. 相似文献

Sport-development programmes provide opportunities for Aboriginal and Torres Strait Islander youth to excel and overcome social inequities. In Australia, all levels of government have identified sport-development programmes in their policy responses as a method to redress inequity amongst this population. Yet, a recent report has shown that national sport organisations have been more reactive in establishing anti-discrimination policy and less proactive in cultivating culturally inclusive programmes and meaningful sporting experiences (Human Rights and Equal Opportunity Commission, 2007). At the same time, neo-liberal approaches to policy in Australia have seen the emphasis on grassroots community sport-development shift to third-sector organisations. However, little research has examined how the third-sector organisations operate with Aboriginal and Torres Strait Islander communities and how culturally inclusive the programmes they deliver are for the communities in which they operate. Three case studies with the objectives of analysing organisational approaches to: structure and governance; sport-development philosophies; and cultural inclusiveness of the programmes, are presented here. The case studies were informed by the cultural lens of Ganma, a theory belonging to the Yolngu community of Yirrkala (Marika, Ngurruwutthun, & White, 1992). The case study method included in-depth interviews with programme leaders, reviews of management information systems and programme observation. The findings provided evidence of the importance of culturally inclusive programmes through governance and an informal lived approach to philosophy and culture. The implications for sports management are discussed, including: the benefits of involving Aboriginal and Torres Strait Islander people at the board level; the need for collaboration between local communities and partners; the explicit need to empower local communities to develop the skills to sustain programmes and outcomes; and the maintenance of mutually beneficial interactions. 相似文献

In this paper I use philosophical accounts on the relationship between trust and knowledge in science to apprehend this relationship
on the Web. I argue that trust and knowledge are fundamentally entangled in our epistemic practices. Yet despite this fundamental
entanglement, we do not trust blindly. Instead we make use of knowledge to rationally place or withdraw trust. We use knowledge
about the sources of epistemic content as well as general background knowledge to assess epistemic claims. Hence, although
we may have a default to trust, we remain and should remain epistemically vigilant; we look out and need to look out for signs
of insincerity and dishonesty in our attempts to know. A fundamental requirement for such vigilance is transparency: in order
to critically assess epistemic agents, content and processes, we need to be able to access and address them. On the Web, this
request for transparency becomes particularly pressing if (a) trust is placed in unknown human epistemic agents and (b) if
it is placed in non-human agents, such as algorithms. I give examples of the entanglement between knowledge and trust on the
Web and draw conclusions about the forms of transparency needed in such systems to support epistemically vigilant behaviour,
which empowers users to become responsible and accountable knowers. 相似文献

In 1998 the Higher Education Funding Council for England (HEFCE)commissioned a survey of the extent to which institutional learning andteaching strategies were being used in English higher education. Thesurvey was seen by HEFCE as a necessary precursor to the enactment ofits policy decision to allocate a component of institutional funding onthe basis of the possession of (and subsequent activation of) aninstitutional learning and teaching strategy. Responses from 116institutions showed considerable variation in the extent to which theyhad developed a strategic approach to learning and teaching.Over the coming years there is likely to be a marked increase in thelevel and sophistication of strategic planning to develop learning andteaching across whole institutions. The article concludes by drawingupon the organisational development literature to suggest some ways inwhich this shift might be facilitated. 相似文献

This paper reports aspects of an international study of leadership of teaching in 19 departments with outstanding teaching records in 11 research‐intensive universities. Leadership was found to take different forms in different discipline areas, in different organisational cultures, and in response to major problems affecting the department. While most of the heads conceived of leadership of teaching in similarly sophisticated ways, and there were other common themes across contexts, how these conceptions were evident in action to support and develop teaching was highly context‐dependent. To illustrate this point, two departments are contrasted in terms of leadership activities found most frequently across all 19 departments. It is clear from this comparison that teaching excellence was achieved in entirely different ways involving widely contrasting leadership behaviour. The paper argues that advice and guidance for heads of department on their leadership of teaching should pay careful attention to the context rather than make assumptions about the general applicability of leadership theory or advice. 相似文献
