朱熹在建构《大学章句》的体系时,采取了一种志与功相统一的说理方法。这种方法既表现在《大学》经章里,也表现在《大学》传章里,而且在不同的说理层次上,存在着不同的志与功的统一,既有纲领之间的志与功相统一,也有条目之间的志与功相统一,这分别体现在经章与传章里,而且基本上呈现出一一对应的关系。  相似文献

新时代对体育强国和体育法治建设提出了新要求,行政执法作为体育强国建设的重要抓手也面临着方式革新的机遇和挑战。简政放权背景下,体育执法面临着“应不应该管、怎样管”的尴尬处境,广为体育行政执法主体运用的强制性执法手段极易加剧执法矛盾,执法的社会效果得不到保障。由于传统执法方式难以适应新时代体育市场监管的现实需要,革新体育行政执法方式就显得尤为必要。面对时代课题,应遵照由“形式优化”到“实质革新”的逻辑,并树立行政平衡、服务合作和正当程序的理念,从引入信用工具、推广非强制性执法和全程说理式执法3个方面推进改革,实现体育行政执法方式的精简化、多元化和法治化。  相似文献

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.  相似文献

This article contributes to the important debate over the conversion of the Turks to Islam. Previously, it was thought that the Turks abandoned their former steppe faith and customs very swiftly to become staunch Sunni Muslims, but this view has recently been challenged by a number of studies. The current consensus seems to be that the Turks’ adoption of Islam was a process of far longer duration, spanning many decades. This article broadens this discussion by demonstrating that the chronicles written by the First Crusaders contain much useful information that is pertinent to this question. It works through these texts, showing that they can shed new light on this point.  相似文献

近年来,大学生身体素质不佳,已成为"老大难",也是刻不容缓需要解决的问题,多地曾出现在体测、运动会、马拉松中晕倒甚至猝死事件,这给学校体育工作的开展带来不小的考验。带着因涉跑引起猝死的疑问,通过猝死案例分析,探究高校大学生猝死的病理学的非运动成因。研究认为:涉跑猝死的主因是先天性生理疾病,运动不是引发猝死的主要诱因,并提出了预防运动猝死的"堵疏结合"的医学监控策略和体医融合防卫机制构建方法。建议通过入校时医学筛查、跑前医学检查、跑中医学观察、猝死现场急救、跑后跟踪复查降低猝死风险;建立宿舍、运动场地、运动项目的全覆盖的心脏复苏志愿队伍,实施"黄金8分钟"内的急救生存链;建立学生、学校、政府、社会四方体育运动分级分类保险制度,从风险转移和人道主义援助进行关怀;建立涉跑猝死、猝死、非正常死亡的数据库,开展非正常死亡人员的病理学研究;建立全生命周期医学监控和健康安全宣传教育,形成全方位、全过程、全人员的体医融合防卫机制。  相似文献

Professional training for designers is crucial in the field of design studies. The characteristics of novices versus those of expert designers have been identified in the literature; however, studies exploring the issue of professional training processes in the actual workplace are not well developed. Our study addresses the topic by using qualitative research methods along with flexible design. Collected data from the interviewees with different work experience were analysed by open, axial and selective coding. Herein, we argue that the processes by which a designer transforms from a novice into an expert in the industry are constructed through the interaction of several complicated factors. The re‐learning inherent in design professions is implemented through knowledge transfer gained from participation in design projects, particularly regarding tacit knowledge. Also, the novice's process of learning and training yields the characteristics and skills that companies and firms require of designers; this process involves a series of disciplinary sub‐processes, from destructive to reconstructive, implemented by employers. In these sub‐processes, the subjectivity of designers is neglected, leading to the suppression of imaginative expression and feelings of alienation among these workers.  相似文献

The present investigation was carried out to examine the incidence and pattern of injuries in adolescent multisport athletes from youth sports academy. Injury data were prospectively collected from 166 athletes during the seasons from 2009 to 2014. A total of 643 injuries were identified, 559 (87.0%) were time-loss injuries. The overall injury incidence was 5.5 (95% confidence interval CI: 5.1–6.0), the incidence of time-loss injuries was 4.8 (95% CI: 4.4–5.2), the incidence of growth conditions was 1.2 (95% CI: 1.0–1.4) and incidence of serious injuries was 0.6 (95% CI: 0.5–0.8) per 1000?h of exposure. The prevalence of overuse injuries was 50.3%. Growth conditions represented 20.0%. Most of the injuries (67.0%) involved the lower extremities, and both foot and ankle were the most predominant injured body parts (22.0%). Knee injuries were mostly from overuse (50 vs. 23, p?=?.02), whereas foot and ankle injuries resulted from an acute mechanism (94 vs. 31, p?<?.0001). Minor and moderate injuries accounted for 87.0%. Muscle, tendon and osteochondrosis injuries accounted for 52.0% of all injuries. Comparing groups, squash sport was having the highest injury incidence (8.5 injuries per athlete). Higher exposure was associated with greater overuse relative risk (RR?=?1.03, 95% CI: 1.01–1.014, p?<?.001). In conclusion, the results of this study identified a high incidence of injuries in this youth sports population. Striking was the prevalence of overuse injuries of 50%, which suggests the need for injury prevention protocols for adolescent highly trained athletes.  相似文献
