当前国内农村土地流转中介组织研究评述

实现农村土地的合理流转是统筹城乡发展和解决"三农问题"的关键,而市场经济条件下,农村土地流转中介组织的健康发展是农村土地合理流转的必要条件。但当前我国学界关于农村土地流转中介组织的研究较少,而且相关的研究存在一定的缺陷和问题,亟待解决和完善。今后的有关研究中,一方面,应拓展研究视角,创新研究方法;另一方面,研究内容应力求完整性、系统性和理论性的统一;同时,对农村土地流转中介组织的研究还要注重指导性、针对性和可操作性的结合。     

《民法典》时代体育协会法人治理的现实困境与疏解策略

基于《民法典》中非营利法人的规范文本,对体育行业协会法人治理的学理内涵做出推演。借助“场域”结构框架分析体育行业协会法人治理问题。“组织域”维度,体育行业协会内部章程及制度不够完善、内部治理结构不健全、法人治理机制功能失调、“会企关系”有待完善。疏解策略包括加强体育行业协会规章制度建设,推进制度资源积累的良性发展;健全治理结构,完善组织机构;遵循会员服务逻辑,提升“会企关系”。“社会域”维度,体育行业协会自治与政府干预边界不清、体育行业法律资源稀缺、体育市场监管体系标准化与规范化程度不够。疏解策略包括政府应强化对改革的顶层设计,在切实为协会赋权的基础上,进一步明确政府监管边界,完善政府对协会的年检与评估机制;强化法律制度供给,完善体育行业立法,将体育行业立法与体育市场治理现状有效衔接,切实赋予协会在体育行业自治领域的立法权、执法权与监管权;发挥体育行业协会的自律功能,借助技术赋能,完善体育行业监管机制的标准化和规范化体系建设,提升体育行业协会的市场监管和服务能力。

Epidemiology of injuries in First Division Spanish football

Abstract

The aim was to examine the injuries sustained by Spanish football players in the First Division and to compare injury-related variables in the context of both competition and training. The injury data were prospectively collected from 16 teams (427 players) using a specific web-based survey during the 2008/2009 season. A total of 1293 injuries were identified (145 were recurring injuries). The overall injury incidence was 5.65 injuries per 1000 h of exposure. Injuries were much more common during competition than during training (43.53 vs. 3.55 injuries per 1000 h of exposure, P < 0.05). Most of the injuries (89.6%) involved the lower extremities, and overuse (65.7%) was the main cause. Muscle and tendon injuries were the most common types of injury (53.8%) among the players. The incidence of training injuries was greater during the pre-season and tended to decrease throughout the season, while the incidence of competition injuries increased throughout the season (all P < 0.05). In conclusion, the results of this study suggest the need for injury prevention protocols in the First Division of the Spanish Football League to reduce the number of overuse injuries in the muscles and tendons in the lower extremities. In addition, special attention should be paid during the pre-season and the competitive phase II (the last four months of the season) in order to prevent training and competition injuries, respectively.     

Changes in repeated-sprint performance in relation to change in locomotor profile in highly-trained young soccer players

Abstract

The aim of this study was to examine the effects of changes in maximal aerobic (MAS) and sprinting (MSS) speeds and the anaerobic reserve (ASR) on repeated-sprint performance. Two hundred and seventy highly-trained soccer players (14.5 ± 1.6 year) completed three times per season (over 5 years) a maximal incremental running test to approach MAS, a 40-m sprint with 10-m splits to assess MSS and a repeated-sprint test (10 × 30-m sprints), where best (RSb) and mean (RSm) sprint times, and percentage of speed decrement (%Dec) were calculated. ASR was calculated as MSS-MAS. While ?RSb were related to ?MSS and ?body mass (r² = 0.42, 90%CL[0.34;0.49] for the overall multiple regression, n = 334), ?RSm was also correlated with ?MAS and ?sum of 7 skinfolds (r² = 0.43 [0.35;0.50], n = 334). There was a small and positive association between ?%Dec and ?MAS (r² = 0.02 [?0.07;0.11], n = 334). Substantial ?MSS and ?MAS had a predictive value of 70 and 55% for ?RSm, respectively. Finally, ?ASR per se was not predictive of ?RSm (Cohen’s = +0.8 to ?0.3 with increased ASR), but the greater magnitude of ?RSm improvement was observed when MSS, MAS and ASR increased together (0.8 vs. +0.4 with ASR increased vs. not, additionally to MSS and MAS). Low-cost field tests aimed at assessing maximal sprinting and aerobic speeds can be used to monitor ?RS performance.     

日本关东大地震期间温州旅沪同乡会的作为

1923年日本发生关东大地震,中国人民曾在财力和物力上给予日本大力帮助,但在军国主义煽动下的日本暴徒趁震灾大肆残杀旅日华工,被惨杀者大部分为浙江温州、处州的侨民。温州旅沪同乡会对归国侨民进行救济,同时与北洋政府交涉,对日抗议。虽然最终由于当时中国国力弱小,此案不了了之,但温州旅沪同乡会的作为体现了当时国人民族意识的增强,也揭露了日本帝国主义的反动本性和北洋政府的无能。     

Dress for fit: An exploration of female activewear consumption

While the female activewear market is growing rapidly, research on activewear consumption and female consumers is lagging. Existing researchers have failed to produce an in-depth understanding of female consumers’ perceptions of activewear, thereby providing limited insights for the activewear industry. Drawing upon brand association theory and the functional, expressive, and aesthetic model, the authors identify important attributes of activewear brands and how attributes lead to benefits pursued by female activewear consumers. Focus groups were conducted with 72 female activewear consumers in Australia. Findings reveal three product-related attributes (functional design, colour, and size and fit) and two non-product-related attributes (price and model imagery) influence the fulfillment of four benefits (mood enhancement, exercise facilitation, healthy and active lifestyle, and physical fit body image). This research contributes theoretical and empirical knowledge about activewear consumption and the vertical structure of brand associations. Findings of this research can help activewear brands deliver benefits to female consumers through improved product designs and marketing strategies.
