The action sport industry is a high growth sector that attracts the lucrative Generation Y market. Although there is a growing body of literature that examines the characteristics and traits of the Generation Y market as consumers of action sports, little is known about the supply side of the action sports industry. This paper illustrates through the example of the skateboarding sport cluster, that this sector has evolved in an organic, almost chaotic manner very different to that of the mainstream sports industry. Entrepreneurs have taken advantage of the open system, the lack of formal boundaries and the risk loving nature of the market to grow the sector into a very profitable industry. The paper specifically illustrates the differences to mainstream sports in relation to provision of facilities, program development and pathways and the roles of suppliers, councils and program developers. 相似文献

This study examined physiological and performance effects of pre-cooling on medium-fast bowling in the heat. Ten, medium-fast bowlers completed two randomised trials involving either cooling (mixed-methods) or control (no cooling) interventions before a 6-over bowling spell in 31.9±2.1°C and 63.5±9.3% relative humidity. Measures included bowling performance (ball speed, accuracy and run-up speeds), physical characteristics (global positioning system monitoring and counter-movement jump height), physiological (heart rate, core temperature, skin temperature and sweat loss), biochemical (serum concentrations of damage, stress and inflammation) and perceptual variables (perceived exertion and thermal sensation). Mean ball speed (114.5±7.1 vs. 114.1±7.2 km · h(-1); P = 0.63; d = 0.09), accuracy (43.1±10.6 vs. 44.2±12.5 AU; P = 0.76; d = 0.14) and total run-up speed (19.1±4.1 vs. 19.3±3.8 km · h(-1); P = 0.66; d = 0.06) did not differ between pre-cooling and control respectively; however 20-m sprint speed between overs was 5.9±7.3% greater at Over 4 after pre-cooling (P = 0.03; d = 0.75). Pre-cooling reduced skin temperature after the intervention period (P = 0.006; d = 2.28), core temperature and pre-over heart rates throughout (P = 0.01-0.04; d = 0.96-1.74) and sweat loss by 0.4±0.3 kg (P = 0.01; d = 0.34). Mean rating of perceived exertion and thermal sensation were lower during pre-cooling trials (P = 0.004-0.03; d = 0.77-3.13). Despite no observed improvement in bowling performance, pre-cooling maintained between-over sprint speeds and blunted physiological and perceptual demands to ease the thermoregulatory demands of medium-fast bowling in hot conditions. 相似文献

This case is written for instructors of classes focused on strategic management, organisational behaviour, human resource management, and/or an officiating course. The case highlights the numerous administrative processes a new employee in a sport organisation would face. Although the case is fictional it is based on the authors’ personal and professional experiences in athletics administration and officiating, and further draws upon the authors’ research in the area of officiating. Consequently, this case study was constructed based on first-hand observation, interviews and conversation with numerous officials and administrators, and through the examination of documents frequently used to manage officials. As a result, the case provides an opportunity for students to critically evaluate and address: (1) a sport organisation's policies and procedures; (2) issues related to human resource management within a sport setting; (3) the managerial response after an organisational failure. 相似文献

Summaries English In an attempt to explain success and failure in problem‐solving by science students, the authors suggest that problem‐solving ability is associated with students’ ability to organize or ‘chunk’ the information provided in a problem into memorizable patterns. In line with general psychological findings, a short‐term memory capacity of 7 ± 2 chunks is accepted. If the short‐term memory is overloaded with too many pieces of information, the processing of this information (and, hence, effective problem‐solving) cannot take place unless such information can be effectively chunked. This hypothesis, which is derived from research studies, is exemplified by reference to chemical problems and its educational implications are discussed. 相似文献

The problem of reducing withdrawal and enhancing the lives of nursing home patients and other elderly members of society becomes more serious as the number of aged increases. Declines in the ability of elderly may be attributable, in certain cases, to disuse of intellectual capacities. Social reinforcement through reading activities has been proposed as a means of enhancing the performance of the aged and relieving the pain of social deprivation. In order to investigate this hypothesis, two reading groups were formed in a 100‐bed convalescent home; each group met for 6 weeks for 45 minutes. Short stories of high interest were read and discussed. Patients appeared to appreciate and enjoy the sessions. Problems of conducting similar programs were discussed and further research suggested. 相似文献
