运用文献资料法对"健康中国2030"背景下全民健身与全民健康深度融合发展的基本态势进行梳理,剖析深度融合的薄弱环节及解决路径。全民健身与全民健康进行深度融合的发展趋势及态势集中体现在习近平总书记关于全民健身以及全民健康的一系列重要讲话、国家政策支撑、发展成果、成果转化与应用四个方面。深度融合存在协同体制机制障碍、法律法规缺失或不完善、供需矛盾协调障碍、交叉领域专业人才不足等薄弱环节。研究建议:需从部门融合和联合设置工作小组、部门和地方政策法规融合及保持延续性、资源融合与供需两端改革、专业融合和人才融合等四条路径进行改革,全方位推进全民健身与全民健康的深度融合发展。  相似文献

According to the goal orientation model, students’ achievement goals and beliefs are interrelated. Within this framework, research and theory have so far assumed that achievement goals are associated with students’ beliefs of causes of success, the latter representing students’ subjective beliefs about the factors contributing to success at school. So far, this line of research has been restricted to a few cross-sectional studies. We examined the temporal relations between achievement goals (mastery, performance-approach, and performance-avoidance goals) and students’ beliefs of causes of success, the latter operationalized by asking the students to rate the subjective importance of diligence, effort, and ability for school success. Achievement goals and beliefs of causes of success were measured twice with a time lag of one school year with a sample of N = 2044 German secondary school students. Cross-lagged panel models were estimated to examine the temporal relations between achievement goals and beliefs of causes of success while controlling for students’ secondary school track, socio-economic status, and Grade Point Average. Former mastery goals were found to be positively related to later importance ratings of diligence for school success; former performance-approach goals were found to be positively related to later importance ratings of ability. Boys and girls were found to display similar relations among constructs but they showed differential mean levels on both the achievement goal constructs and the beliefs of causes of success. Implications for research on achievement goals and practice using intervention approaches are discussed.  相似文献

Despite the success of academic advising dashboards in several higher educational institutions (HEI), these dashboards are still under-explored in Latin American HEI's. To close this gap, three different Latin American universities adapted an existing advising dashboard, originally deployed at the KU Leuven to their own context. In all three cases, the context was the main ruling factor to these adaptations. In this paper, we describe these adaptions using a framework that focuses on four different elements of the context: Objectives, Stakeholders, Key moment and Interactions. Evaluation of the adapted dashboards in the three different Latin American universities is conducted through pilots. This evaluation shows the value of the dashboard approach in different contexts in terms of satisfaction, usefulness and impact in academic decision-making and advising tasks. The main contribution of this paper is the systematic reporting of the adaptations to an academic advising dashboard and showing the value of an academic advising dashboard on academic decision-making and advising tasks.  相似文献

The present study investigates the relationship between CEO’s information literacy and innovation in small and medium-sized enterprises (SMEs). Even if information literacy’s business value has been recognized in recent literature, its impact on organizational innovation, a critical and strongly information intensive process, has never been studied before. Structural equation modeling based analysis of data collected from 184 company CEOs in Finland revealed that CEOs’ information literacy has a positive impact on the development of exploratory and exploitative innovations in SMEs. Additionally, opportunity recognition mediates the relationship between information literacy and innovation. Overall, the influence of information literacy is slightly stronger on exploitation than exploration. Nevertheless, the mutual positive effect suggests that information literacy enhances innovation ambidexterity in organizations. Based on these findings, we discuss theoretical and practical implications as well as future research opportunities in workplace information literacy research.  相似文献

This study examines the impact of the caste-class association on enrolment in elementary education in Uttar Pradesh (UP), the largest state of India. Using data from the 71st round of NSSO, with the help of a probit model, it is found that class has a stronger impact on the enrolment ratio than caste in UP. There is a strong and direct association between caste and class at the extremes of the caste system. The association between upper-caste and upper-class significantly augments the enrolment ratio, while the association between lower caste and lower class adversely affects it. However, the cross-associations at the higher side of class, i.e., lower caste with the upper class significantly augments enrolment but the association between lower class with upper-caste is found to be adversely affecting the enrolment, though some of the interaction terms are insignificant statistically. This also ensures the dominance of class effect. This pattern is observed in the case of both rural and urban UP across genders.  相似文献

运用文献研究法、饱和经验法、典型案例分析法对苏、浙、沪三省市地方足球协会进行实证研究,依据软法制定主体和实施主体的不同,提炼概括了当前地方足球协会的两种软法治理模式,即省级层面地方足球协会"政府主导型"软法治理模式和市级层面地方足球协会"多维互动型"软法治理模式,并对这两种模式的特征进行比较分析。继而归纳了当前地方足球协会软法治理"程序缺失、责任制度不规范、承诺滞后和权利救济缺失"的四个困境,从"内部法人治理结构、相关主体法治观念、软法的程序、监督问责机制"四个方面阐释了产生软法治理困境的原因,最后提出四项地方足协软法治理的对策建议。  相似文献
