为探究国外运动减肥研究的热点内容和演化趋向，以Web of Science核心合集中的SCI-EXPANDED、SSCI、A&HCI为来源数据库，对其中运动科学领域减肥研究的1 211篇文献进行科学计量和文本内容分析。结果显示：（1）有34个国家和地区的学者对运动减肥进行研究。2004年之后，逐渐形成内容丰富的研究体系；（2）研究演进过程可分为萌发、快速发展、深入发展和领域拓展四个阶段；（3）主要聚焦于减肥对健康的影响、减肥的方式方法、减肥后如何防止体重恢复等热点主题；（4）呈现四个方面的发展特征，研究对象越来越有针对性，研究内容从减肥健康原理向减肥方式方法的应用性转化，干预手段从单一运动方案向多重组合方式转变，研究结果倾向量化的数据指标反映关联关系。  相似文献   

重大体育赛事对城市经济发展的影响--基于中国70个大中城市面板数据分析     

毛丰付  郑芳  朱书琦 《上海体育学院学报》2020,(5):24-36

重大体育赛事的举办在一定程度上能推动承办城市转型发展,但也可能对当地经济产生某种不良影响,这主要源于对重大体育赛事与城市经济发展的内在规律和作用机制认识不够清晰。以2000-2017年22项具有全国影响力的重大体育赛事为基础,利用中国70个大中城市面板数据,采用双重差分法,分析重大体育赛事对城市经济发展的影响。发现:全样本数据下重大体育赛事的举办会促进城市第一产业向第二、第三产业发展;对比国内和国际赛事,重大体育赛事对第三产业的促进作用均显著高于第二产业;以1 085家上市公司数据为样本,采用事件研究法进行分析,发现不同行业利用重大体育赛事的窗口期存在显著差异。  相似文献   

Juggling competing activities: academic staff as doctoral candidates     

Jan Smith  Jennie Billot  Lynn Clouder  Virginia King 《高等教育研究与发展》2020,39(3):591-605

ABSTRACT

This article explores the experiences of a group of established academic staff in New Zealand and the UK, as they undertake a doctorate in their home institutions. Our interest is in how individuals negotiate this dual status from a cultural-historical activity theory (CHAT) stance that explores how rules, tools, community and divisions of labour, and interacting activity systems, shape doctoral experiences. The focus in this article, having analysed their detailed narrative accounts, is on how academics experience three interdependent activity systems: those surrounding the thesis, the institutional context, and the home-life spheres. Issues related to time, workload and supervision issues, variability in collegial support and impact on personal priorities and time emerged. There is a range of particularities – from easy access to resources/supervisors to inflexible institutional regulations – applicable to this group of doctoral candidates. Negotiating life as an academic with concurrent doctoral candidature provides positive outcomes in terms of teaching, research confidence and general personal and professional development. However, a range of difficulties can also be encountered, particularly in relation to personal and professional relationships, and workload management.  相似文献   

Graduate teaching assistants: motives,difficulties and professional interactions and their relationship to perceived benefits     

Fadia Nasser-Abu Alhija  Barbara Fresko 《高等教育研究与发展》2020,39(3):546-560

ABSTRACT

Graduate students play a major role in teaching in higher education, particularly in undergraduate programs. The purpose of the present study was two-fold: first, to identify graduate students’ motives for working as graduate teaching assistants (GTAs), describe some aspects of their work, and ascertain their perceived benefits; second, to predict GTAs’ benefits as a function of their individual background characteristics, motives, job difficulties, and richness of professional interactions with the course instructor. Data were collected from 189 GTAs who led discussion groups at a large research university in Israel by means of an internet questionnaire. Findings revealed that graduate students accepted the position of GTA mainly for extrinsic reasons, such as salary and convenience. They claimed to have faced few difficulties and that their professional interactions with the course instructors focused more on job responsibilities and less on pedagogical issues. They reported having gained a greater understanding of course content and improved teaching skills due to their experience as GTAs. Richness of contact with the course instructor, motives, difficulties, and faculty match significantly contributed to predicting perceived benefits. The implications of the results are discussed.  相似文献

温州经济发展存在的问题及对策——基于温杭甬台绍金经济指标的比较     

郑文秀 《温州职业技术学院学报》2014,(2):42-46

温州经济发展面临着“追兵渐近、标兵渐远”的态势。通过温杭甬台绍金在总量指标、质量指标、投资指标、出口指标和消费指标五大经济指标的比较分析发现，温州经济发展存在高商务成本、投资生态圈未戍形、中心城市扩容窄、物流平台拓展落后、深陷民间借贷和联保等问题。在当前重大转型升级期，温州应采取打好互保链这张牌，改善软环境，借城市经济“外推”服务业等切实有效的措施，用以助推温州经济进一步发展。  相似文献
