This study investigated the acute endocrine responses to a 164-km road cycling event in a hot environment. Thirty-four male experienced cyclists (49.1 ± 8.3 years, 86.8 ± 12.5 kg, 178.1 ± 5.1 cm) participating in a 164-km road cycling event were recruited. Blood samples were collected within 0.3–2.0 h before the start (PRE: ~0500–0700 h) and immediately following the ride (POST). Samples were analysed for testosterone, growth hormone (GH), cortisol and interleukin-6 (IL-6). The temperature and humidity during the event were 35.3 ± 4.9°C and 47.2 ± 14.0%, respectively. Based on the finishing time, results for the fastest (FAST, 305 ± 10 min) and the slowest (SLOW, 467 ± 31 min) quartiles were compared. At POST, testosterone concentration was significantly (P < 0.05) lower (PRE, 20.8 ± 8.6; POST, 18.2 ± 6.7 nmol · L?1), while GH (PRE, 0.3 ± 0.1; POST, 2.3 ± 0.3 µg · L?1), cortisol (PRE, 661 ± 165; POST, 1073 ± 260 nmol · L?1) and IL-6 (PRE, 4.0 ± 3.4; POST, 22.4 ± 15.2 pg · mL?1) concentrations were significantly higher than those at PRE. At POST, GH and cortisol were significantly higher for the FAST group than for the SLOW group (GH, 3.6 ± 2.0 and 1.0 ± 0.8 µg · L?1; cortisol, 1187 ± 209 and 867 ± 215 nmol · L?1). Participation in an ultra-endurance road cycling event in a hot environment induced significant acute changes in concentrations of circulating hormones, with a greater augmentation of GH and cortisol in those completing the ride fastest. 相似文献

Government-led interorganizational alliance networks present a sensible opportunity to overcome many societal challenges through collaborative governance. In particular, few researchers have studied alliance networks in the field of energy conservation in commercial buildings—a sector with unique barriers to greater diffusion of innovative cost-saving strategies. We applied an analytic inductive case-based method and social network analysis to study one particular alliance network: the United States Commercial Building Energy Alliances representing interests from retail, commercial real estate, and healthcare sectors. This alliance network was initiated by the United States Department of Energy, with assistance from several federally funded research laboratories in the United States, to promote the diffusion of knowledge and ultimately encourage greater deployment of energy efficiency and clean energy strategies in commercial buildings. We draw upon interview data from 28 cases of private, non-profit, and governmental organizations and complete network data from the alliance participants. We honed in on eight focal cases of governmental organizations to provide insight on how the four forms of energy and environmental data, information, and knowledge shared within an alliance network address the challenge of a vastly underutilized energy resource, namely conservation. Further, we identify and discuss the public's four roles—Commissioner, Interpreter, Marketer, and User—in providing balance to the diffusion of both private and public goods in a network. 相似文献

There is widespread consensus in the research and policy‐related literature over the last decade that young people who have been permanently excluded from school are at a far greater risk of a variety of negative outcomes than young people who have not had this experience. These negative outcomes include prolonged periods out of education and/or employment; poor mental and physical health; involvement in crime; and homelessness. This article presents evidence from a small‐scale qualitative study of destinations and outcomes post‐exclusion for a group of young people considered to be at particular risk of such negative outcomes: namely, those who have been permanently excluded from special schools or Pupil Referral Units (now known as short‐stay schools). The specific focus of this paper is on the 24 young people's educational trajectories pre‐ and post‐exclusion; the reasons for their exclusion from school; and on what forms of alternative provision were available to them after their permanent exclusion. 相似文献

The New Left of the sixties has been eulogized in the mass media in recent years. Former activists have entered specific employment areas associated with the public sector, although many have retained a political commitment consonant with their previous activities and beliefs. Using interview data gathered in Canada, the Federal Republic of Germany and the United States in 1977 and 1978, the author analyzes the nature and trajectory of the New Left. He finds that the ambivalent character of the movement was an expression of the relations of a specific generation of learners to the deterioration of the condition of intellectual labor in society.The author wishes to thank the Canada Council and the Social Sciences and Humanities Research Council for generously supporting the research. 相似文献

ABSTRACTReligion in Britain is in overall decline and ‘no religion’ is growing, but one-third of schools in the State sector in England and Wales are ‘schools with a religious designation’ (‘faith schools’). Historically, these were Protestant and Catholic Church schools, but new faith schools have been established by Churches and other faiths. Governments of all parties have encouraged this development, chiefly on the grounds of increased parental choice and improved quality.The research presented here provides evidence about the operation of faith schools in the English city of Leicester in 2016, particularly from the perspective of those choosing a school. The main objectives are (1) to indicate the diversity of faith schools, (2) to show how they present themselves to those looking for a school: their admission requirements and level of educational attainment and (3) to reflect on the claim that faith schooling offers more and better choice and quality. Leicester is selected for its size and diversity; it is small enough to study with the resources available to us and is one of the most multi-ethnic and multifaith urban areas in England. Research was carried out between February and July 2016 and offers a snapshot from that year. 相似文献
