以新时代党和国家领导人关于民族工作的重要论述以及《新疆的文化保护与发展》《新疆的若干历史问题》白皮书为指导,研究认为,对中华母体体育文化的认识有待提高、文化属性的缺位相对明显、不良宗教文化的附着存在较大可能以及游牧文化的离散成为常态,是新疆少数民族传统体育发展过程中面临的特殊性文化困境。上述文化困境产生的主要原因在于:在新疆少数民族传统体育发展中,存在着机械性\"华夷之辩\"观念的浸入、对文化属性认知的不足、文化差异的过度强调、现代化进程中的文化迷失等四方面问题。破解新疆少数民族传统体育发展中的文化困境,需要从转变思想观念,给予新疆少数民族传统体育准确定位;加强多方引导,深化对新疆少数民族传统体育文化属性的认识;树立明确观念,客观认识新疆少数民族传统体育中的文化差异;推进体育文旅,促进新疆少数民族传统体育文化和产业的融合发展等四方面展开。  相似文献

Sports science research is traditionally monodisciplinary despite calls for an interdisciplinary focus. The primary purpose of this systematic review was to identify studies on talent identification, talent selection and competition performance to determine whether interdisciplinary research is being conducted. Thirty-six studies met the selection criteria. These studies were critiqued relative to sport, skill level, sport science sub-disciplines included, and whether the research was multidisciplinary or interdisciplinary. The secondary purpose of the review was to critique the level of analysis and level of representative task design in performance tests used in the studies. Twenty-five studies were categorised as interdisciplinary, with 11 categorised as multidisciplinary. Thirteen sports were represented with soccer the most frequent followed by field hockey, Australian Rules football, handball and rugby league. Thirty-two studies completed their analysis at a group level and four at an individual level. A total of 337 performance tests were rated for representative task design with 64 categorised as low, 123 as medium and 150 as high. The results pertaining to interdisciplinary studies and individual analyses are discussed in relation to constraints theory, which predicts that interacting variables can explain sport performance. Sports science research is beginning to fulfil the call for interdisciplinary research. Future research, however, needs to consider individual analyses and representative task design of tests to progress sports science knowledge.  相似文献

基于深度学习算法的进步,人工智能逐渐有能力独立进行发明创造和文艺作品创作。本文主要探讨现行专利及著作权制度中规定的保护对象、权利人资格、专利及著作权的权属、侵权判定、侵权责任主体等对人工智能技术快速发展的适应及协调程度,研究指出:现有的专利和版权制度应当对人工智能的发明和作品持鼓励的态度,在排除不适宜作为专利或著作权保护对象的同时,人工智能的发明或作品的权利授予标准应当与人类的有所区分;相关权利人仍须对应自然人或法人,而非人工智能本身;相关专利侵权行为应包括间接侵权,同时应对人工智能作品安排“登记-授权”的著作权制度、参考临摹作品为人工智能绘画作品提供相应的授权使用制度等。本文还探讨了当前的专利法及著作权法在人工智能时代符合公平原则的程度,并提出解决方案:在“强人工智能时代”将人工智能的发明创造或作品作为公共财产,授予相应的开发者“数据处理权”作为一种新的邻接权,赋予人工智能创造物新的特别权利(Sui Generis),修改专利法与著作权法中关于主要权利的相关规定等。  相似文献

Abstract

The aim of this study was to determine whether endurance training in athletes induces airway inflammation and pulmonary function disorders. Respiratory pattern and function were analysed in ten healthy endurance runners at rest, during sub-maximal exercise, and during the recovery. Inflammatory cells and metabolites (histamine, interleukin-8, and leukotriene E4) were measured in sputum at rest and after exercise. The experiments were conducted on three different occasions (basic endurance training, pre-competitive and competitive periods). In spite of the absence of post-exercise spirometric changes and respiratory symptoms, airway cells counts and inflammatory markers changed significantly. At the beginning of the experiment, athletes' induced sputum showed an abundance of macrophages compared with neutrophils. We found a high percentage of neutrophils during the pre-competitive and competitive periods of the sport season (41% and 37%), a significant increase in macrophage counts during the pre-competitive period (51%), and a significant rise in total cells, interleukin-8, leukotriene E4, and histamine during the competitive period. In conclusion, one year's training increased markers of inflammation in the airways of endurance runners without symptoms or changes in pulmonary function, suggesting that airway inflammation is of insufficient magnitude to markedly impact lung function in healthy athletes.  相似文献

社会建构论:心理学研究的一种新取向   总被引:1,自引:0,他引:1  
隶属于后现代心理学思潮的社会建构论,开始于20世纪80年代中期,由格根所倡导。它一开始便竭力瓦解现代心理学的基石,全面挑战现代心理学的传统解释,在心理学界发起了一场理论革命。它在与现代主流心理学的遭遇战中,兼容了非主流的人主义心理学(如人本主义心理学、精神分析心理学)的主张,注重整体性、历史情境性、价值涉入。同时也改造了科学主义心理学如认知心理学、认知发展科学,成为发展他们的新鲜血液。  相似文献

This paper reports an action research project in a school in the UK designed to investigate the impact of a brief Video Interaction Guidance (VIG) intervention in promoting skills of non-teaching staff in positive behaviour management. A summary of the literature in relation to VIG is provided before describing the project and data collected. Ten teaching assistants (TAs) from a secondary school took part in an intervention using VIG. The impact on TA skills and confidence was assessed using participant ratings of the specific target outcomes of the intervention using the Target Monitoring and Evaluation (TME) system. Participants’ experiences of the intervention were explored during a focus group discussion after the intervention had taken place. TME data suggested a positive impact on TA skills and confidence to support individual pupils, while thematic analysis of focus group data showed a number of themes relevant to the application of VIG in this context, including promotion of effective staff development.  相似文献

Post-apartheid South Africa manifests poor social indicators with over half the population living below the poverty line and the worst levels of inequality in the world, with much work needed to overcome the skewed legacy of apartheid. Sport suffered in this system resulting in unequal access to sporting facilities and opportunities, meaning many South Africans cannot exercise their right to play. Despite this legacy, sport can fulfil a vital developmental role in alleviating some of these issues. The state has a major role to play but it must be supported by civil society and non-governmental organisations (NGOs) who have the ability to deliver in situations where government has struggled. This article researches the opportunities and challenges NGOs encounter when using sport for development within the education system, in post-apartheid South Africa. This study used a qualitative approach to collect data on the opportunities and challenges encountered by two NGOs based in Cape Town that use sport as a means of development, but in markedly different ways. The study suggests that NGOs face a variety of conceptual, technical, logistical and organisational challenges using sport in schools and should enact certain measures to reduce resistance from educators and ensure successful programmes. The interaction between NGOs, schools and the state Department of Education is a complicated process that presents obstacles and opportunities. Nevertheless, despite these challenges it is clear NGOs can support schools in South Africa to optimise their physical activity programmes in the backdrop of a stagnating education system and a lack of sporting support from the government. NGOs in an educational setting such as schools operate in what Houlihan has identified as a crowded policy space. Yet, the observations in this study suggest that, particularly in the context of education, a partnership policy model of NGO work is preferred.  相似文献
