改革开放40年高等体育教育资源优化配置的社会学审视     

张孔军  钱娅艳 《北京体育大学学报》2019,42(2):103-114

摘要：我国高等体育教育资源优化配置研究引入社会学视角理论与方法，理论与实践均取得专家的认同。运用文献资料法、专家访谈法和实地考察法等方法发现，在计划经济体制下我国高等体育教育资源配置主体单一性、手段行政化和政治倾向性强，凸显出高等体育教育资源配置缺乏激励机制和市场竞争机制的问题，造成高等体育教育资源配置成本最大化和社会效应的最小化问题较多。自改革开放以来,随着我国市场经济体制的建立为高等体育教育资源优化配置提供了难得的发展机遇，我国高等体育教育资源配置取得了明显成效，但仍然存在高等体育教育资源配置机制滞后、体制机制改革创新步伐缓慢、高等体育教育资源配置不合理以及民办普通高校体育教育资源配置严重不足等问题。据此，从社会学研究的视角，提出了构建多主体推动高等体育教育资源优化配置创新的发展模式、多元化高等体育教育资源优化配置资金投入的保障体系、高等体育教育资源优化配置均衡发展的运行机制和大学城体育教育资源“共建共享”的创新发展模式的新时代我国高等体育教育资源优化配置的发展策略，旨在服务新时代全民健身与全民健康深度融合发展，“推动构建人类命运共同体”发展目标的实现。  相似文献

Neural embedding-based indices for semantic search     

Fatemeh Lashkari  Ebrahim Bagheri  Ali A. Ghorbani 《Information processing & management》2019,56(3):733-755

Traditional information retrieval techniques that primarily rely on keyword-based linking of the query and document spaces face challenges such as the vocabulary mismatch problem where relevant documents to a given query might not be retrieved simply due to the use of different terminology for describing the same concepts. As such, semantic search techniques aim to address such limitations of keyword-based retrieval models by incorporating semantic information from standard knowledge bases such as Freebase and DBpedia. The literature has already shown that while the sole consideration of semantic information might not lead to improved retrieval performance over keyword-based search, their consideration enables the retrieval of a set of relevant documents that cannot be retrieved by keyword-based methods. As such, building indices that store and provide access to semantic information during the retrieval process is important. While the process for building and querying keyword-based indices is quite well understood, the incorporation of semantic information within search indices is still an open challenge. Existing work have proposed to build one unified index encompassing both textual and semantic information or to build separate yet integrated indices for each information type but they face limitations such as increased query process time. In this paper, we propose to use neural embeddings-based representations of term, semantic entity, semantic type and documents within the same embedding space to facilitate the development of a unified search index that would consist of these four information types. We perform experiments on standard and widely used document collections including Clueweb09-B and Robust04 to evaluate our proposed indexing strategy from both effectiveness and efficiency perspectives. Based on our experiments, we find that when neural embeddings are used to build inverted indices; hence relaxing the requirement to explicitly observe the posting list key in the indexed document: (a) retrieval efficiency will increase compared to a standard inverted index, hence reduces the index size and query processing time, and (b) while retrieval efficiency, which is the main objective of an efficient indexing mechanism improves using our proposed method, retrieval effectiveness also retains competitive performance compared to the baseline in terms of retrieving a reasonable number of relevant documents from the indexed corpus.  相似文献

梁金辉  胡智勇  胡德刚 《首都体育学院学报》2020,(3):233-240

借鉴ACSI顾客满意度测评指数模型,结合中国群众性马拉松赛事的特点,运用探索性因子分析法建立中国马拉松赛事参赛者满意度测评指标体系,基于此,构建中国马拉松赛事参赛者满意度测评指数模型。研究发现:中国马拉松赛事参赛者满意度测评指数模型的指标包括参赛者期望、硬服务质量感知、软服务质量感知、感知价值、参赛者满意度、参赛者抱怨、参赛者忠诚度7个因素。就各个自变量对中国马拉松赛事参赛者满意度的影响路径来看,参赛者对服务的预期通过对软服务质量感知、硬服务质量感知间接正向影响中国马拉松赛事参赛者满意度;参赛者的服务质量感知既直接又间接地正向影响参赛者的满意度,参赛者的软服务质量感知通过硬服务质量感知和感知价值间接正向影响参赛者的满意度,参赛者的硬服务质量感知通过感知价值间接正向影响参赛者的满意度。就各个自变量对中国马拉松赛事参赛者满意度的影响程度而言,参赛者的软服务质量感知对其满意度影响最大,其次依次为硬服务质量感知、服务期望和感知价值。  相似文献   

Is academic tracking related to gains in learning competence? Using propensity score matching and differential item change functioning analysis for better understanding of tracking implications     

《Learning and Instruction》2020

This study analyzes gains in cognitive components of learning competence with respect to cohorts based on ability tracking in a Czech longitudinal study. Propensity score matching is used to form parallelized samples of academic and non-academic track students and to eliminate the effect of selective school intake. We applied regression models on the total scores to test for the overall track effect. Furthermore, we analyze scores and gains on the subscores and check for differential item functioning in Grade 6 and in change to Grade 9. While after 3 years, no significant difference between the two tracks was apparent in the total learning competence score, we did, however, find significant differences in some subscores and in the functioning of some items. We argue that item-level analysis is important for deeper understanding of the tracking implications and may provide the basis for more precise evidence-based decisions regarding the tracking policy.  相似文献   

Role of teacher-related factors and educational resources in science literacy: An international perspective     

《Studies in Educational Evaluation》2020

The study evaluated the relationship among teaching, leadership, teacher certification, student and teacher number related factors, and index of economic, social and cultural status (ESCS), and science literacy from an international comparative perspective. 2015 dataset of the Programme for International Student Assessment for Turkey, Singapore, the United States, Korea, Italy, and Brazil was used. Two-level hierarchical linear models were established for analysis. Results revealed that school ESCS was the best predictor of science literacy across six countries and additionally teacher-related factors came to the forefront of science literacy performance. The study underlined policymakers should focus primarily on policies that increase equity in education. Furthermore, the effectiveness of investments made in factors related to leadership, teacher certification, the number of students and teachers, which contribute very little to science literacy performance, need to be more questioned. Inferences about the findings were discussed in detail, and recommendations for further research were made.  相似文献   

基于动态分阶势场法的船舶自动避碰系统     

罗贤程  尹建川  李宏宾 《上海海事大学学报》2020,41(1):1-7

为使船舶在多船避让环境下适应航行环境的变化并自动复航,提出基于动态分阶势场法的船舶自动避碰系统。该系统基于动态势场避障规划算法,利用模糊综合评价法量化船舶碰撞危险度;依据《国际海上避碰规则》确定本船在不同会遇局面下的避让行动,并据此对斥力势函数进行调整。该系统将本船的避碰过程划分为航迹保持、避让和复航3个阶段,根据不同阶段的要求构建动态分阶势场;利用动态分阶势场法对船舶的航行环境进行建模,进而生成恰当的航向指令;利用自动舵产生舵角指令控制船舶完成避让、复航和航迹保持。仿真结果表明:该自动避碰系统可以引导船舶完成既定的避让行动,并能使船舶在安全会遇距离上驶过;该系统可以适应航行环境的变化,且具备航迹保持能力。  相似文献
