We examined the effects of time of day on a cycling time trial with and without a prolonged warm-up, among cyclists who tended towards being high in "morningness". Eight male cyclists (mean +/- s: age = 24.9 +/- 3.5 years, peak power output = 319 +/- 34 W, chronotype = 39 +/- 6 units) completed a 16.1-km time trial without a substantial warm-up at both 07:30 and 17:30 h. The time trial was also completed at both times of day after a 25-min warm-up at 60% of peak power. Power output, heart rate, intra-aural temperature and category ratings of perceived exertion (CR-10) were measured throughout the time trial. Post-test blood lactate concentration was also recorded. Warm-up generally improved time trial performance at both times of day (95% CI for improvement = 0 to 30 s), but mean cycling time was still significantly slower at 07:30 h than at 17:30 h after the warm-up (95% CI for difference = 33 to 66 s). Intra-aural temperature increased as the time trial progressed (P < 0.0005) and was significantly higher throughout the time trials at 17:30 h (P = 0.001), irrespective of whether the cyclists performed a warm-up or not. Blood lactate concentration after the time trial was lowest at 07:30 h without a warm-up (P = 0.02). No effects of time of day or warm-up were found for CR-10 or heart rate responses during the time trial. These results suggest that 16.1-km cycling performance is worse in the morning than in the afternoon, even with athletes who tend towards 'morningness', and who perform a vigorous 25-min warm-up. Diurnal variation in cycling performance is, therefore, relatively robust to some external and behavioural factors.  相似文献

Points of convergence: seamless long-term access to digital publications and archival records at library and archives Canada   总被引：1，自引：0，他引：1  

Greg Bak  Pam Armstrong 《Archival Science》2008,8(4):279-293

In 2004, Canada’s national library and national archives merged to form Library and Archives Canada (LAC). LAC has become more than the sum of its parts, creating synergies between library and archives collections and services, realizing efficiencies and satisfying user demands for seamless access to all holdings. LAC has already created and launched Fed Search, an online search tool that provides clients with single-search access to library, archives and online collections. LAC is in the process of building a Trusted Digital Repository that will combine ingest, preservation, management and dissemination services for archives and library collections.  相似文献

From Opposition to Engagement: Lessons from High Achieving African American Students     

Greg Wiggan 《The Urban Review》2008,40(4):317-349

Influential research on African American students has examined their school failure in terms of students’ opposition to school achievement. Only a few studies have explored school engagement and success among these students, and even fewer have examined the experiences of high achieving black students. This study illustrates the school context and school processes that high achieving African American students identify as contributing to their academic success. The findings reveal three main school effects impacting the students’ performance: 1) teacher practices, engaging pedagogy versus disengaging pedagogy; 2) participation in extracurricular activities and; 3) the state scholarship as performance incentive. According to the students, teacher practices were the most instrumental school effect benefiting their outcomes. Recognizing the processes that promote high achievement among African American students can help to improve our understanding of student performance, while promoting success among these students. The author wishes to thank Ron DePeter and Tekla Johnson for their comments on a previous draft of this article  相似文献   

‘Not Merely an Isolated Game’: Women’s Association Football in Australia     

Greg Downes  Ian Syson  Roy Hay 《国际体育史杂志》2015,32(18):2150-2170

ABSTRACT

Australia has participated in the world-wide growth of women’s football particularly since the 1970s, but long before that the game was played recreationally and competitively by women in Australia. Women have struggled to overcome active opposition to their taking part in the sport and neglect of their achievements which are considerable. This article provides an outline of the history of the game both nationally and in its international context. It also tries to capture the experience of some of the pioneers of the women’s game and its modern practitioners, revealing some of the ways in which overt and covert discrimination still hinders recognition of their achievements.  相似文献   

Travelling home(s): contemporary Korean art after the postcolonial     

Michelle Bae  Greg Dimitriadis 《Discourse: Studies in the Cultural Politics of Education》2015,36(3):314-328

Contemporary discussions of globalisation (in general) and postcolonialism (more specifically) have largely remained wed to critiques of the West, including around its outsized role in the proliferation of neoliberal economic logics. As Chen argues in Asia as Method, these discussions have precluded other kinds of discussions about globalisation and its ‘theories’ – those that are generated between Asian countries and peoples (recognising that ‘Asia’ itself is a construction). In this essay, we look towards a different kind of conversation about the postcolonialism, one that does not take the West as its primary interlocutor. We will look closely at two South Korean contemporary artists – Do Ho Suh (1962–) and Kimsooja (1957–) – and see how they work through contemporary, material concerns around ‘home’ and ‘place’. In particular, these artists point us towards ‘movement’ as a trope for displacing extant concerns with fixed identity and as a kind of ontological state of being in the world.  相似文献
