诗及思想的历史性变局——对北京市西城地域文化的一种解读

北京西城曾蕴蓄着中国历史文化的巨大变局。从清末到民国初期,许多对近代中国文坛以及政坛产生极大影响的著名诗人和思想家都曾在西城区驻足停留,他们的著述反映了清末和民国初期中国文化与政治思潮的轨迹。可以说,＂变局文化＂之西城是中国微观文化地理方面的一大独特景观。     

军民科技资源共享博弈与治理研究

从经济、科研和制度三个方面,分析军民科技资源共享的基础条件,研究军民科技资源共享过程存在的现实困境。采用博弈理论方法,构建军民科技资源主体间的资源共享博弈模型,结果表明某一科技资源主体的预期共享收益(效用)不仅要高于其不共享科技资源时的收益,还与另一科技资源主体共享资源量、共享概率有关,并受到该主体对共享资源的吸收、利用能力影响。基于博弈分析结果和共享困境,从共享观念、法律制度、平台、标准体系、管理体制等方面,提出一系列的有效治理策略。     

北京郊区参与型体育旅游资源时空演化特征及影响因素

体育旅游已成为中国当前体育产业转型升级和旅游消费的热点。为科学认识大都市周边体育旅游资源空间分布特征并优化资源开发布局,本文以北京郊区为案例地,在对参与型体育旅游资源（Participatory Sport Tourism Resources, PSTR）分类基础上,运用空间分析等方法,探讨了1998、2008和2018年参与型体育旅游资源的时空演化特征及影响因素。研究发现：①北京郊区参与型体育旅游资源分为休闲娱乐型、拓展运动型和刺激探险型3类;经统计,休闲娱乐型资源数量最多,刺激探险型资源数量最少但增速最快;就资源集聚度而言,刺激探险型>拓展运动型>休闲娱乐型。②北京郊区PSTR空间分布整体呈现“东南密、西北疏”的特征,且随距中心城区距离的增加,PSTR数量波状递减;1998、20008和2018年北京郊区PSTR分布由西北向东南演进,且趋向中心城区布局的特征越来越显著,PSTR集聚峰值区由距中心城区30~40 km逐步缩减至20~30 km;3类资源的时空演化格局存在显著差异。③北京郊区PSTR空间格局的形成受地形、水系、人口、交通、政策与规划等自然和人文因素的综合影响,在不同因素作用下3类资源呈现不同的空间分布规律。其中,交通是影响空间分布的基础性因素,政策与规划因素发挥着关键性引导作用,一定程度上塑造和强化了PSTR的空间格局。以上研究发现对进一步优化北京郊区体育旅游资源的开发和体育旅游产业的合理布局具有重要理论和实践意义。     

我国退役奥运会冠军社会流动研究

研究运用文献资料法和数理统计法,分析我国退役奥运会冠军的社会流动情况,主要从代际流动和代内流动两方面探讨了导致我国退役奥运会冠军社会流动的原因,研究发现:我国退役奥运会冠军社会流动以向上流动为主。并且发现我国退役奥运会冠军社会流动受社会环境、家庭因素和其他个人自致因素的影响,其中,家庭因素对我国退役奥运会冠军的社会流动影响最大。     

第三帝国时期的德国体育及其语言

纳粹统治时期种族主义盛行,体育运动也未能自外其中,沦为国家政治的工具。而体育术语本土化的规范,似是黑暗政治中的一道学术微光。本文采用文献分析法,以1936年柏林奥运会及《奥林匹克手册》为例,对该时期的德国体育战略及体育语言工作进行分析。     

北京冬奥会筹备对运动休闲基地建设的示范作用研究

北京冬奥会雪上项目将在张家口市崇礼区进行,冬奥会筹备工作的重点也就集中在了这个过去名不见经传的小镇上了。虽然距冬奥会开幕还有近2年的时间,但崇礼区作为滑雪运动圣地已蜚声海内外,国外专业滑雪运动队将它作为训练基地外,国内业余滑雪运动者也从全国各地涌向这里。如今,张家口市整个经济被冬奥会激活了,其产业结构也已因崇礼区滑雪运动休闲基地实现了从农业经济向资源旅游经济的转型。虽然冬奥会筹备是国家级的大事,但张家口崇礼区的建设筹备仍然对全国休闲运动基地建设具有示范指导意义。     

Systems model and individual simulations of training strategies in elite short-track speed skaters

This study aimed to evaluate the effect of simulated training strategies on performance potential in elite short-track speed skaters. Training load and field-based criterion performances from fifteen athletes (10 males, 5 females) were collected over a 3-month training period and the relationship between training loads and performance was computed with a variable dose-response model using a genetic algorithm. Individual simulations of tapers preceded or not preceded by an overload training (OT) were assessed. We obtained a significant correlation between actual and modelled performances (R² = 0.76 ± 0.07). Regarding model parameters, no significant difference was found between males and females but the time to recover performance tended to be lower in females. Simulations in which the taper parameters were free highlighted that an exponential or a step taper were the most effective for increasing performance compared to a linear taper (p < 0.05). Optimal exponential taper duration after OT was 10.7 ± 2.4d and the optimal load reduction was 75.9 ± 3.7%. OT intensity had the greatest influence on the predicted performance, followed by OT duration, taper decay, and to a lesser extent load reduction during taper and taper duration. Thus, a variable dose-response systems model allows the evaluation of different taper strategies and their potential effect on performance changes.     

Did London 2012 deliver a sports participation legacy?

Despite the increasing academic interest in the analysis of the Olympic legacy, there is a relative knowledge gap as far as sports participation legacy is concerned. The authors bridge this gap by analysing the short-term sports participation legacy of the London 2012 Olympic and Paralympic Games on the adult population in England. By using data from the Active People Survey and considering different sports participation variables and the effect of the economic climate, results demonstrate a positive association with participation from hosting the Games. Participation rates were adjusted to take into account seasonality and changes in the gross domestic product (GDP), accounting in this way for the effect of the recent economic recession. The biggest effect was observed in relation to frequent participation (at least three times per week for at least 30 min) in the year immediately after the Games. In 2014, the sports participation rates fell relative to 2013 but remained higher than pre-Olympic levels. The sport participation legacy of the Olympic Games appeared to have significant differences between socio-demographic groups.     

Interorganisational conflict between national and provincial sport organisations within China’s elite sport system: Perspectives from national organisations

In this article, the authors examine interorganisational conflict between provincial and national sport organisations in China. The authors theoretically ground the research in work related to interorganisational relationships and interorganisational conflict. The three case studies are artistic gymnastics, swimming, and cycling, and the authors conducted interviews with 11 staff from the relevant national-level sport organisations. Secondary data was sourced from official publications, websites, and influential domestic media. The key finding is that, whilst famed for its top-down bureaucratic system, there is considerable interorganisational conflict within the Chinese sport system. The extent and characteristics of the national-provincial conflict vary between sports. But there is also some consistency regarding the causes of the conflict and the measures adopted to mitigate the tension. Interorganisational conflict provides a useful heuristic for articulating and understanding the interorganisational relationships within the Chinese elite sport system and hence advances elite sport management research.     

我国优秀青少年男排运动员专项体能特征的评价研究

运用文献资料、专家访谈、录像观察和数理统计等科研方法,以东京奥运周期中23届和24届羽毛球世锦赛成绩为主要依据,分析我国男子羽毛球发展现状及各国在各单项上的竞技实力,前瞻东京奥运会周期世界男子羽毛球竞争格局。结论如下：我国男子羽毛球队虽然取得了不少成绩,但也面临着人才青黄不接、年轻选手比赛经验不足,心理素质较差、技战术观念滞后等的尴尬局面。在竞争格局上,中国男子羽毛球队在世界羽坛上的优势地位遭到了严峻挑战,以丹麦为首的西方国家羽毛球队实力逐渐增强,亚欧之间的竞争力呈缩小之态势。在男子单打项目上,呈现出群雄逐鹿的局面;男子双打项目,则呈现出三足鼎立之势;混双方面,我国实力强劲,力压群雄,保持着较强的竞技水平。
