对旅游本质研究方法论的思考   总被引：1，自引：0，他引：1  

王中华  高建富 《宜宾学院学报》2009,9(7)

对相关概念认识的不统一及研究视角的不同,是导致学界在旅游本质问题上长期存在分歧的重要原因。胡塞尔有关"本质"层级的论述,为这一问题的研究提供了有价值的思考。旅游本质研究的起点应是旅游的"单个体"本质,"旅游"之内涵则是指"旅游活动",研究的视角应是哲学的视角,即时空视角。  相似文献   

磁场处理对绿豆幼苗超氧化物歧化酶活性的影响     

李巍  刘汉平 《德州学院学报》2011,27(4):33-35

研究了绿豆幼苗经过不同强度、不同持续时间的磁场作用后,采用氯化硝基氮蓝四唑（NBT）光照还原法,测定了绿豆幼苗的超氧化物歧化酶（SOD）活性的变化规律.结果发现磁场处理诱导了SOD的活性,处理后的幼苗SOD活性明显高于对照组,并且SOD活性随磁场强弱和持续时间连续变化,在特定磁感强度或者特定持续时间时,SOD活性有一个极大值.可见适当的磁场激励可比较明显的增强绿豆幼苗的SOD活性,提高植物的抗逆性.  相似文献

旅游活动对吐鲁番维吾尔族传统手工技艺保护的影响研究     

田振江 《丹东师专学报》2011,(3):153-156,F0003

改革开放以来,吐鲁番地区旅游业的发展取得了喜人的成绩,同时,吐鲁番地区拥有类型多样的维吾尔族传统手工技艺。文章以旅游活动为视角,重点分析了旅游相关群体即政府部门、旅游企业、当地居民和旅游者对吐鲁番维吾尔族传统手工技艺保护的态度,在此基础上,探讨了旅游活动对传统手工技艺保护的积极影响和消极影响,并进一步分析了二者之间的关系。  相似文献   

What about sport? A public health perspective on leisure-time physical activity     

《Sport Management Review》2015,18(1):20-31

In an effort to determine how sport could be better positioned on the public health agenda, three community physical activity programs aimed at combating obesity were examined to determine the benefits residents seek through their participation. Using a case study approach and critical framework, assumptions and presumed knowledge of these public health programs were drawn out through site visits and interviews. A total of 42 interviews with community leaders, program organizers, and residents in each community were conducted. The results reveal that new approaches need to be considered for promoting greater levels of participation in U.S. community sport and other leisure-time physical activity programs. Instead of the commonly emphasized benefits of physical health or appearance, the results demonstrate that hedonic rewards and opportunities for social interaction are two overlooked, yet primary benefits sought by participants. This research suggests that concerted efforts to focus on the hedonic feelings and social aspects can potentially lead to increased sport participation and holistic health. Such an approach may help better address vital public health policy issues while demonstrating the distinctiveness and utility of sport.  相似文献   

Running into trouble: constructions of danger and risk in girls' access to outdoor space and physical activity     

Sheryl Clark 《Sport, Education and Society》2015,20(8):1012-1028

This paper considers girls' participation in running and other outdoor physical activities in their local areas in London, UK. The paper is concerned with the operation of risk discourses in and around this participation and looks at the way that such discourses impacted on girls' opportunities to take part in physical activities that required outdoor space. Drawing on data from longitudinal research into girls' participation in sport and physical activity, the findings suggested that girls, in particular, were subject to risk discourses around their participation in physical activities which constructed the girls as ‘weak’, and ‘vulnerable’. I look at the ways in which girls understood these messages and how they came to define certain spaces and activities as either ‘safe’ or ‘unsafe’. I look in particular at how girls were able to resist certain constructions of their embodied physical capacities and also at the ways in which this was constrained by specific incidences of sexual harassment.  相似文献   

青少年运动缺乏症研究的10大问题     

Avery D. Faigenbaum  Thomas M. Best  James MacDonal  Gregory D. Myer  Andrea Stracciolini 《北京体育大学学报》2015,38(11):50-58

摘要：运动缺乏症（EDD）是一种儿科疾病,特点是中高强度体力活动（MVPA）下降,低于目前的推荐量,也与积极的健康结果（health outcomes）不一致。目前,大多数儿童和青少年符合EDD的诊断标准,因为他们没有达到日常MVPA的最低要求。本文的目的是强调10个与青少年EDD有关的重要研究问题。需要进行重要的研究来更好的定义EDD的临床表现,包括评估体力活动行以确定开始出现EDD的年龄或发育阶段;包括运动技巧和体能的运动起源（kinesiogenesis）的检测;以及对影响青少年MVPA的生活方式因素的评估。关于治疗EDD的干预措施和政策的研究问题,包括评估对卫生保健从业者进行运动医学重要性的教育和训练;确定在临床上识别和治疗EDD青少年的方法的有效性;开发敏感的、特效的、经济的方法以诊断青少年EDD;以及定制方法以促进本病诊疗的医疗保险赔付。如果未来研究不能优化EDD青少年的识别、治疗和管理方案,具有重大影响的生物医学、心理、经济和政治的新的卫生保健问题将会不断出现。  相似文献

Tracking of physical activity in pubertal boys with different BMI over two-year period     

Triin Rääsk  Kenn Konstabel  Jarek Mäestu  Evelin Lätt  Toivo Jürimäe  Jaak Jürimäe 《Journal of sports sciences》2015,33(16):1649-1657

We examined the tracking of physical activity (PA) measured by accelerometers and subjective self- and parental reports in normal weight and overweight and obese pubertal boys over two-year period. In total, 156 boys with mean (±SD) age of 11.53 ± 0.76 at baseline and with mean age of 13.94 ± 0.74 at 2 year follow-up were studied. At baseline and approximately two years later, the boys completed self-report questionnaire and wore an accelerometer for seven consecutive days. On the basis of first year assessment’s body mass index (BMI), the children were grouped as normal weight and overweight and obese groups according to BMI cut-offs. Tracking correlations of objectively measured PA and subjectively measured PA were fairly similar across the 12–14 year-old-boys weight groups over two year period. Tracking correlations of objectively measured PA and subjectively measured PA were not significantly different over two-year period between both BMI groups. The results of the study show that pubertal boys objectively measured PA decreased over two-year period and so the boys started to be less active in their pubertal period.  相似文献
