Critically reflexive dialogue and praxis: Academic/practitioner reflections throughout a formative evaluation of Circles® USA

Reflections about the use of critically reflexive praxis by academic/practitioners are offered based on a case study of a formative evaluation of Circles^® USA, a nonprofit organization coordinating initiatives across the U.S. working to move families out of poverty. Critically reflexive praxis is theorized as featuring several themes including acknowledging different levels of context, critical dialogue with collaborators, engaging cultural difference and intersectionalities, problematizing power relations and relationships among researchers and collaborators, and occurring throughout the research project. Examples of critical dialogic reflexivity and navigating common tensions that emerge throughout such community engagement projects are detailed during three phases: planning and design; fieldwork and interviews; and outcomes, applications, and implications.

感兴说与道禅文化思想的渊源

中国古典美学中的感兴说指的是艺术创作中的灵感兴发现象。与西方文艺理论中的灵感说大不相同,它包括五个方面。其一,灵感兴发的神秘源泉:体道通神;其二,灵感兴发的诱因和物质载体:自然万物;其三,灵感兴发的主体状态:葆真全性,回归自然;其四,灵感兴发的主观条件:凝神、妙悟;其五,灵感兴发的本质涵义:天人感应天人合一。所有这五个方面,无不基于道家和禅宗哲学思想。     

知识员工对雇主信任的影响因素研究

文章首先对知识员工、雇主以及知识员工对雇主信任的概念进行了界定。在对大量相关文献进行梳理的基础上，结合知识员工对雇主信任的特征，归纳出信任的五个影响因素，分别为：雇主的正直、能力、关心、公平以及提供的报酬。进而提出相关性和影响性两组假设，并构建出知识员工对雇主信任影响因素的概念模型。实证部分在问卷设计和样本收集的基础上，使用SPSS软件对数据进行处理，利用相关分析、回归分析对文中的假设进行检验，最后得出结论：雇主的正直、能力、关心、公平，是知识员工对雇主信任的四个影响因素，并具有显著的影响效果。     

基于SEM的民俗体育进高校影响因素评价研究

通过构建影响因素量表,提供可供参考的影响因素体系,指导民俗体育的实践,推进民俗体育的现代化发展,形成探索民俗体育发展的共识、方法。建立SEM模型,并经过多次修正,判断影响因素的合理性、科学性,得出:民俗体育的"活动形式"是影响其现代化发展的首要因素;引导"管理者认知",推进"项目价值探索",赢取"学校支持";"源自于民间-发展于高校-回馈于社会"——课内外一体化的教学模式实现民俗体育"软着陆";回归身体价值本质探索民俗体育发展之路。     

Self-reported symptoms and risk factors for digital ischaemia among international world-class beach volleyball players

The prevalence of ischaemia-related symptoms is remarkably high among elite indoor volleyball players. Since the exposure to sport-specific demands may be higher in beach volleyball compared to indoor volleyball, the aim of this study was to assess the prevalence of ischaemia-related symptoms and associated risk factors among world-class beach volleyball players. Therefore, a questionnaire survey was performed among beach volleyball players active during the 2013 Grand Slam Beach Volleyball in the Netherlands. In total, 60 of the 128 beach volleyball players (47%) participated: 26 males and 34 females from 17 countries. The self-reported prevalence of cold or blue or pale digits in the dominant hand during or immediately after practice or competition was 38% (n = 23). Two risk factors were independently associated with symptoms of blue or pale digits: more than 14 years playing volleyball (odds ratio (OR) 4.42, 90% confidence interval (90% CI) 1.30–15.07) and sex (female) (OR 4.62, 90% CI 1.15–18.57). In conclusion, the prevalence of symptoms associated with digital ischaemia is high among international world-class beach volleyball players. Female sex and the length of the volleyball career were independently associated with an increased risk of ischaemia-related symptoms. The high prevalence of these seemingly innocuous symptoms and possible associated risk factors warrant regular monitoring since early detection can potentially prevent thromboembolic complications and irreversible tissue damage.     

黑龙江省冰雪装备制造业创新成长影响要素与战略研究

随着我国成功申办2022年冬奥会,我国将大力发展冰雪运动,并会随之带动旅游、经济和冰雪装备制造业的发展。而冰雪装备制造业的发展直接影响我国冰雪体育事业的开展。采用文献资料、调查、系统分析等研究方法,针对黑龙江省冰雪装备制造业的创新成长问题进行研究,并对黑龙江省的冰雪装备制造业创新成长影响要素以及企业创新成长存在的问题进行分析与总结,认为黑龙江省冰雪装备制造业创新成长的总体状况是良好的,但企业存在资金短缺,经营、管理、技术等方面人才匮乏,企业产品结构单一、产品科技创新意识和能力不强,欠缺可持续发展理念等问题。通过分析影响冰雪装备制造业创新成长的原因,提出引进与自我创新相结合、注重品牌质量、发扬政府主导优势等战略,旨为冰雪装备制造业在黑龙江省的发展提供理论依据。

龙宫水溶洞的成因分析

文章分析了龙宫水溶洞的形成机制,认为龙宫水溶洞是在地层地貌基础、水动力条件和断裂构造等因素的影响下形成的一个地下伏流系统。在新构造运动的影响下,喀斯特作用的向深性不断增强,水溶洞的局部顶板崩塌,使完整的伏流系统分解为五段地下水溶洞,称为"五进龙宫"。龙宫的龙门瀑布与黄果树瀑布在形成机理上有一定的相似性。
