身体关怀:徐英超体质教育思想的形成动因、内在逻辑与当代启示     

邵天逸  李启迪 《沈阳体育学院学报》2020,(3):23-28

徐英超是"体质教育思想"的首创者,这一思想在我国学校体育发展史中具有重要的地位。运用文献资料法、逻辑分析法,通过不同的视角深度剖析徐英超体质教育思想,旨在呈现徐英超体质教育思想的形成动因与内在逻辑,并挖掘体质教育思想对当前学校体育的启示。研究认为徐英超体质教育思想的成因在于反思体育的概念,内在逻辑包含3个方面:体育教学的视点应从技术传习回归身体教育,实证调研是揭示与掌握体质变化规律的关键,良好的心态与生活方式是促进体质健康的外部保障。徐英超体质教育思想的当代启示:正视增强体质与技术教学之关系;参考体测结果调整体育教学方向;建构面向生活的体育健康教育观。  相似文献   

Information retrieval in the workplace: A comparison of professional search practices     

Tony Russell-Rose  Jon Chamberlain  Leif Azzopardi 《Information processing & management》2018,54(6):1042-1057

Legal researchers, recruitment professionals, healthcare information professionals, and patent analysts all undertake work tasks where search forms a core part of their duties. In these instances, the search task is often complex and time-consuming and requires specialist expertise to identify relevant documents and insights within large domain-specific repositories and collections. Several studies have been made investigating the search practices of professionals such as these, but few have attempted to directly compare their professional practices and so it remains unclear to what extent insights and approaches from one domain can be applied to another. In this paper we describe the results of a survey of a purposive sample of 108 legal researchers, 64 recruitment professionals and 107 healthcare information professionals. Their responses are compared with results from a previous survey of 81 patent analysts. The survey investigated their search practices and preferences, the types of functionality they value, and their requirements for future information retrieval systems. The results reveal that these professions share many fundamental needs and face similar challenges. In particular a continuing preference to formulate queries as Boolean expressions, the need to manage, organise and re-use search strategies and results and an ambivalence toward the use of relevance ranking. The results stress the importance of recall and coverage for the healthcare and patent professionals, while precision and recency were more important to the legal and recruitment professionals. The results also highlight the need to ensure that search systems give confidence to the professional searcher and so trust, explainability and accountability remains a significant challenge when developing such systems. The findings suggest that translational research between the different areas could benefit professionals across domains.  相似文献   

试论《明人十二像册》高度写真风格的中国渊源     

黄乐乐 《美育学刊》2020,11(2):116-120

现藏于南京博物院的一批无款写真头像《明人十二像册》,是中国写实画的一座高峰。对于这个像册的绘画风格,现当代学者多半都偏向认为是受到西方绘画的影响。但经与西方圣像画比较研究,像册仍属于中国本土的绘画传统,受到了宋代山水画和花鸟画高度写真精神的影响。  相似文献   

大学生孤独感对手机成瘾倾向的影响:生命意义感的调节作用     

陆娟  宫火良 《保定学院学报》2020,(3):95-100

为了探究大学生孤独感、手机成瘾倾向和生命意义感之间的关系,采用UCLA孤独量表、大学生手机成瘾倾向量表、人生意义感问卷,选取408名大学生作为被试进行问卷调查。结果发现:(1)孤独感与手机成瘾倾向呈显著性正相关,生命意义感与手机成瘾倾向呈显著性负相关,孤独感和生命意义感相关性不显著;(2)孤独感和生命意义感都显著预测手机成瘾倾向,生命意义感在孤独感和手机成瘾倾向之间的调节效应显著,低生命意义感大学生的孤独感对手机成瘾倾向的预测力更强。因此,大学生的孤独感能正向预测手机成瘾倾向,生命意义感能调节二者之间的关系,低水平的生命意义感会加剧孤独感对手机成瘾倾向的预测作用,而高水平的生命意义感会使孤独感对手机成瘾倾向的影响较小。  相似文献   

Extended Validation of the Korean Version of the Quality of Life Survey     

SeYun Park  Erin Reifsteck  Diane L. Gill 《Measurement in physical education and exercise science》2019,23(2):110-117

In this study, we examined the factor structure and reliability of the Korean Quality of Life (KQoL) survey and compared the KQoL survey to both the World Health Organization Quality of Life-Brief Version (WHOQOL-BREF) and the Satisfaction with Life Scale (SWLS). We also assessed associations between KQoL scores and physical activity (PA) participation. Participants were 557 (male = 281, female = 276) healthy Korean adults with ages between 18 and 71 years (M = 33.2, SD = 14.2). Results of confirmatory factor analyses confirmed the 7-subscale model and indicated acceptable values supporting convergent validity (χ² = 1,678.758, df = 443, p < .001, RMSR = .045, RMSEA = .071, TLI = .880, CFI = .892). Correlations of KQoL subscales with similar subscales of WHOQOL-BREF and with SWLS supported concurrent validity. Results confirm that the KQoL survey can assess multidimensional aspects of quality of life (QoL), including spiritual, physical, social, and psychological. KQoL scores were positively related to PA participation, in line with previous research supporting the positive association of PA with QoL.  相似文献

Cross-Cultural Adaptation and Psychometric Properties of the Portuguese Version of the Life Skills Scale for Sport     

José Roberto Andrade do Nascimento-Junior  Leonardo de Sousa Fortes  Gabriel Lucas Morais Freire  Daniel Vicentini de Oliveira  Lenamar Fiorese  Lorcan Donal Cronin 《Measurement in physical education and exercise science》2020,24(1):11-24

ABSTRACT

This research adapted the Life Skills Scale for Sport (LSSS) into Portuguese and provided evidence for its construct validity. Study 1 included four translators and five academics who developed a Portuguese version of the LSSS (P-LSSS). During this study, evidence for the content and substantive aspects of construct validity was provided using an expert panel and 25 sports participants. Study 2 included 413 participants that completed the P-LSSS. Within this study, evidence for the structural aspect of construct validity was provided via factor analyses. Study 3 included 134 participants who completed the P-LSSS and a measure of motivation. This study provided evidence for the external aspect of construct validity, with results showing more self-determined motivation had positive relationships with participant’s life skills development. Overall, our findings provided evidence for the construct validity of P-LSSS scores. Researchers and practitioners can use the P-LSSS to assess life skills development within sports participants.  相似文献   

Positivity and quality of college life of business students: The mediating role of learning approaches     

《Studies in Educational Evaluation》2020

Drawing upon the causal agency theory, this study examined the direct and indirect (via learning approaches) links between positivity and quality of college life (QCL) of business students in a transitioning market, Vietnam. Two studies were conducted to test these relationships using structural equation modeling. Findings from study 1, based on a sample of 428 business students, showed that positivity was positively related to QCL. Further, deep learning approaches mediated the relationship between positivity and QCL. Findings from study 2, based on a sample of 416 business students, reconfirmed the role of positivity in QCL. However, the indirect relationship between positivity and QCL was not significant, demonstrating that surface learning approaches did not mediate the relationship between positivity and QCL. The findings contribute to the literature on positivity in higher education by confirming the overarching role that positivity plays, directly and indirectly (via deep learning approaches), in QCL.  相似文献

吕娇娇  黄灵燕  刘宇 《上海体育学院学报》2020,(5):63-69,80

目的观察12周惯性哑铃练习对轻度认知损害(MCI)老年人认知功能、身体活动能力、生活质量和睡眠质量的影响,并探讨认知改善与其他功能改变之间的关系。方法将45名MCI老年人随机分为干预组(n=22)和对照组(n=23)。干预组受试者进行惯性哑铃练习(3次/周,60 min/次,持续12周),对照组不进行运动干预。结果 12周后,干预组受试者阿尔茨海默病评定量表-认知部分(ADAS-Cog)总分/指令得分、蒙特利尔认知评估量表(MoCA)评分、起立行走计时(TUG)和SF-36健康调查问卷(SF-36)心理总得分均显著改善(均P<0.05)。与对照组相比,干预组受试者ADAS-Cog总分/单词回忆得分/注意力得分、简明精神量表(MMSE)评分、TUG和匹兹堡睡眠指数(PSQI)的改善程度均具有显著差异(P<0.05或P=0.05)。偏相关分析结果显示,SF-36心理总得分改变(r=-0.712)、PSQI改变(r=-0.380)与认知改善程度均呈显著负相关。结论 12周惯性哑铃练习可显著提高MCI老年人的认知功能,并对其移动能力、生活质量和睡眠质量具有积极影响,且心理和睡眠改变程度可能影响认知功能的改善效果。  相似文献   

余华小说《第七天》中的生与死     

王雪 《四川教育学院学报》2014,(8):64-66

《第七天》是余华继《兄弟》七年之后完成的最新一部长篇小说，描绘了主人公死去后所经历的事情以及勾起的回忆，为读者展现了一个平等、和谐的死亡世界。经过分析，作品中的生死问题包括三个方面：作品中的人物对死亡没有痛苦或恐惧，能够理性地看待死亡；生与死的意义被颠倒，死亡世界接近理想中的现实世界，更加引人向往；生与死由“爱”这条纽带联系起来，让人们在冰冷中感受到温情。这部小说暴露了大量的社会现实，引人深思，也备受争议。  相似文献
