Fear as political dynamics: Chinese peasant workers’ struggle over social security

This article attempts to understand the subject formation of Chinese peasant workers by exploring the emotional dynamics of their struggle for social security, in particular, the new political possibilities created by emotional forces, and the complex ways they experience and articulate the distinctive kind of emotional politics that binds peasant workers with the state in their co-production of emotionally charged power relations, identities, and subjectivities. It formulates an analytical framework that explores the emotional politics of fear that plays out in the context of economic restructuring. In contemporary China, the conflict triggered by social insurance contributions has become a component of the ensuing social crisis, where many protest events are triggered by widespread outrage at the violation of legal rights to social insurance and other welfare security. This research focuses on the struggle of a group of peasant workers at a UNIQLO supplier in Shenzhen, exploring how their fears for the future are constituted, and how their emotional feelings of insecurity motivate collective action and reconfigure their emotional identity and subjectivity in the face of extreme risk. Informed by a relational understanding of emotions, this paper investigates the complex ways in which the proliferation of fear, as a result of an anticipated pain in the future, articulates the process of subject-making in the face of increasing instability and precarity. The study attempts to demonstrate the centrality of fear for China’s sociopolitical order and the radical action of labor resistance.     

Influence of Cultural Orientations on Electronic Word-of-Mouth (eWOM) in Social Media

This study explores how horizontal/vertical individualism and collectivism (HVIC) orientations influence electronic word-of-mouth (eWOM) (i.e., opinion leadership and opinion seeking) in social media. Online survey panel data through Amazon MTurk were collected from American social media users to address the research purpose. The results, using the structural equation modeling, show that the paths from horizontal individualism to opinion leadership, vertical individualism to opinion leadership and opinion seeking, horizontal collectivism to opinion leadership, and vertical collectivism to opinion leadership and opinion seeking were significant. This study provides theoretical and managerial implications regarding the influence of HVIC orientations on eWOM in social media.     

Effects of periodic carbohydrate ingestion on endurance and cognitive performances during a 40-km cycling time-trial under normobaric hypoxia in well-trained triathletes

The purpose of this study was to examine CHO ingestion on a cognitive task using a field-simulated time-trial (TT) under hypoxia in well-trained triathletes. Ten male triathletes (age: 22.1 ± 1.1 years; VO₂max: 59.4 ± 1.4 ml/kg/min) participated in this double-blind/crossover/counter-balanced design study. Participants completed 3 TT trials: 1) normoxic placebo (NPLA; FiO₂ = 20.9%), 2) hypoxic placebo (HPLA; FiO₂ = 16.3%), and 3) hypoxic CHO (HCHO; 6% CHO provided as 2 ml/kg/15 min; FiO₂ = 16.3%). During the TT, physiological responses (SpO₂, HR, RPE, and blood glucose/lactate), cognitive performance, and cerebral haemodynamics were measured. Hypoxia reduced TT performance by ~3.5–4% (p < 0.05), but CHO did not affect TT performance under hypoxia. For the cognitive task, CHO slightly preserved exercise-induced cognitive reaction speed but did not affect response accuracy during hypoxic exercise. However, CHO did not preserve the decreased Hb-Diff (cerebral blood flow, CBF) and increased HHb in the prefrontal lobe (p < 0.05) during hypoxic exercise, and CHO failed to preserve hypoxia-suppressed prefrontal CBF and tissue oxygen saturation. In conclusion, the present study demonstrates that CHO is effective in sustaining reaction speed for a cognitive task but not promoting TT performance during hypoxic exercise, which would be important for strategy-/decision-making when athletes compete at moderate high-altitude.     

上海市小学生余暇体育行为的影响因素研究——基于休闲限制理论视角

运用文献资料法、问卷调查法和访谈法,从休闲限制理论的视角,对上海市小学生余暇体育行为的影响因素进行研究。结果表明：自身限制、人际限制和结构限制共同影响上海市小学生的余暇体育行为,自身限制主要体现在小学生自身健康状况差、余暇兴趣内容静态化、自身掌握的余暇体育知识与练习方法缺失;同龄玩伴、家长和教师构成小学生余暇体育行为的人际限制因素;余暇体育的时间限制、体育场地器材缺乏和余暇体育氛围不足是结构限制因素。针对这些限制因素提出构建学生余暇体育行为养成体系、多途径增强家长体育意识、完善公共体育服务体系等建议。     

乒乓球运动员以预防损伤为主的功能训练

功能训练的理念来源于康复领域,现已逐步应用到运动训练中。由于乒乓球运动的项目特征,乒乓球运动员肩关节、腰椎关节、膝关节、踝关节、腕关节等部位容易出现运动损伤。通过对乒乓球运动员常出现的功能问题进行分析,寻找存在的常见问题,进而提出相应的功能训练建议。乒乓球运动员可根据情况,增加改善肩关节、胸椎关节、髋关节、踝关节的活动范围的训练,提高肩胛骨、核心和下肢稳定性的训练,以及改善肩袖、躯干肌力不平衡的训练,通过针对性的功能训练有效减少乒乓球运动员损伤的发生。     

学校武术教学内容建构的路径思考

回顾与展望：关于我国青少年体育健康公共服务的述评与研究*

青少年体育健康问题上升国家战略高度。“青少年体育健康公共服务”是一个在青少年体育领域内,由“体育健康”和“体育公共服务”综合而成的全新概念,学界还未深入探讨与挖掘。充分结合“健康管理”理论,基于对“青少年体育健康”和“体育公共服务”相关研究文献的回顾,归纳“青少年体育健康公共服务”内涵与特征。概念特征包括：“学校体育”“青少年体育俱乐部”是核心供给主体;健康医疗等事业、非营利性机构是重要支撑;始终强调青少年受众被动接受“体育健康促进”与主动应用“体育健康素养”相结合;供给产品具有“纯公共物品”性质,公共财政补贴是解决公共服务资源配置矛盾关键方式;“互联网虚拟社区”是实现多元主体协同供给的技术基础与激励条件。最后,基于概念属性展望“青少年体育健康公共服务”的未来研究趋势,包括：开发“运动干预”“心理调试”和“营养膳食”三维评估指标体系;完善“学校”“社区”“医疗部门”“健康管理机构”和“家庭”的协同供给机制;深度开发“青少年体育俱乐部”和“青少年联赛体系”营造“体育健康素养培育”空间;实现“青少年体育健康公共服务”均等化局限,以及加快“青少年体育健康公共服务”互联网平台建设,破解公共服务资源闲置问题。     

基于新鲜度和配送成本的易腐食品配送路径

为解决企业在制定易腐食品配送计划时难以权衡配送总成本与交付产品的新鲜度的问题,建立以配送总成本最低和交付产品平均新鲜度最大为目标,带时间窗的易腐食品配送路径规划模型。采用自适应差分进化(differential evolution,DE)算法求解模型,通过数值算例验证模型和算法的有效性。与基本DE算法和基本蚁群算法的求解结果进行对比,自适应DE算法的求解结果更优,收敛速度更快。求得的帕累托解集表明配送总成本与交付产品平均新鲜度相悖,增加少量的配送成本可以使交付产品的平均新鲜度得到大幅提升。对易腐食品保质期、时间窗宽度和车辆装载量进行灵敏度分析,为企业在不同配送情景下在配送总成本与交付产品的平均新鲜度之间的权衡提供参考。     

考虑充电和等待时间的集装箱码头AGV调度

为提高自动化集装箱码头自动导引小车(automated guided vehicle,AGV)作业效率和利用率,考虑AGV的电量续航能力和重空载的耗电差异,在AGV任务选择时综合考虑任务距离和各任务紧急程度,并设置AGV充电结束条件以减少AGV排队等待的时间,建立以最小化完成任务总时间为目标的AGV调度模型。用Java进行实例求解。结果表明,对AGV采用多频次充电并将其允许工作电量百分比设定为71%时,完成任务总时间最短,耗电量最小,且AGV利用率较高。
