高校体育场馆对外开放突发事件的应急管理机制研究     

王骏  刘海荣  何宁宁  廖大伟 《沈阳体育学院学报》2020,(2):125-132

运用文献资料、实地调查等研究方法,对我国高校体育场馆对外开放突发事件应急管理现状进行调查分析。发现目前我国高校体育场馆对外开放过程中,存在缺乏突发事件应急预案的研制、对安全风险评估不足、缺乏急救设施的配置、场馆现场管理人员缺乏应急管理的培训与演练、场馆现场管理人员数量不足的问题。在高校体育场馆突发事件应急管理发展现状基础上,依托应急管理理论与应急救援理论,架构由突发事件识别与评估模块、决策系统模块、应急救助体系模块、应急预案选择模块、应急救援的执行模块所组成的我国高校体育场馆对外开放突发事件应急管理机制。建议:完善场馆管理规章制度,形成场馆对外开放突发事件应急长效管理机制;加强员工的应急管理理论培训与技能学习;制定各类应急预案并进行演练;保持突发事件应急救援稳定的对外联系畅通。  相似文献   

Rare-aware attention network for image–text matching     

《Information processing & management》2023,60(3):103280

Image and text matching bridges visual and textual modality differences and plays a considerable role in cross-modal retrieval. Much progress has been achieved through semantic representation and alignment. However, the distribution of multimedia data is severely unbalanced and contains many low-frequency occurrences, which are often ignored and cause performance degradation, i.e., the long-tail effect. In this work, we propose a novel rare-aware attention network (RAAN), which explores and exploits textual rare content for tackling the long-tail effect of image and text matching. Specifically, we first design a rare-aware mining module, which contains global prior information construction and rare fragment detector for modeling the characteristic of rare content. Then, the rare attention matching utilizes prior information as attention to guide the representation enhancement of rare content and introduces the rareness representation to strengthen the similarity calculation. Finally, we design prior information loss to optimize the model together with the triplet loss. We perform quantitative and qualitative experiments on two large-scale databases and achieve leading performance. In particular, we conduct 0-shot test for rare content and improve rSum by 21.0 and 41.5 on Flickr30K (155,000 image and text pairs) and MSCOCO (616,435 image and text pairs), demonstrating the effectiveness of the proposed method for the long-tail effect.  相似文献   

Sustaining What is Valuable: Contours of an Educational Language About Values     

LOVISA BERGDAHL  ELISABET LANGMANN 《Journal of Philosophy of Education》2020,54(5):1260-1277

Making liberal democratic values meaningful to study in schools is a more complex issue than being a question of turning values into explicit educational goals (Schleicher) or of curing a motivational deficit (Critchley). Since values seem to play an important role in the practices and commitments of people's everyday lives, values are calling for a continual refinement of our words in relation to the world (Laverty). The purpose of this article is to offer contours of an educational language about values that acknowledges this refinement and the pedagogical work that teachers might do—by way of language—in order to sustain the living-on of what is valued and valuable to us as individuals and as societies. To this end, the article is divided into two parts. The first part takes the temperature of the current political and educational debates, offering thereby a sociopolitical background to the need of a renewed language about values. Drawing on ordinary language philosophy (Moi, Murdoch and Forsberg) and the idea that there is an intimate relationship between how we look at the world (attention) and the words we use in describing it (language). The second part of the article places the emergence of values in a particular time in history before suggesting a more existential vocabulary about values for the purpose of teaching values in schools.  相似文献   

职业体育赛事球迷观赛动机的国外研究综述     

张轶  Jerred Junqi WANG 《湖北体育科技》2020,(1):5-8,64

职业体育中高度变化的商业环境凸显了在管理、营销和服务等领域研究消费者动机的重要性。国外学者对球迷观赛动机进行了深入的研究,并取得了很多有价值的研究成果。本文从球迷观赛动机的3个组成构面:球迷忠诚度、球迷内在动机和球迷外在动机,分析动机因素对职业体育赛事消费的影响;基于对国外现有研究的梳理和述评,本文进一步解析上述研究成果对我国职业体育的管理体制、运行机制、塑造品牌、观众服务等方面的可应用性,并提出学术研究方向上的新建议。  相似文献   

体育产业高质量发展系统动力机制模型建构与现实考察     

薛昭铭  刘东升  马德浩 《沈阳体育学院学报》2020,(2):116-124

通过文献资料法和案例分析法,以系统论为视角对体育产业高质量发展进行动力机制模型建构,并以江苏体育产业发展经验作为现实考察。研究认为:体育产业高质量发展作为政策性议题,其实践取向应围绕产业的商业性效益逻辑和体育的人文性功能价值进行有机融合,进而推动体育产业在社会主要矛盾、资源配置方式、产业结构模式、经济增长状态4个维度中积极寻求转向。推进体育产业转向高质量发展是一个系统问题,系统运转的关键在于形成运动项目内涵丰富的内生机制、社会进步和经济发展环境的外发机制以及业态载体和空间载体充沛的内外联动机制。当前运动项目产业化内在张力不足、外部环境要素缺位、空间载体培育良莠不齐是现实挑战。提出注重深度内涵式发展、强化务实载体建设、营造适宜外部环境3个由意识理念引领到具体工作抓手的发展思路。  相似文献   

Motivation profiles of urban preservice teachers: Relations to socialization,initial career perceptions,and demographics     

《Contemporary educational psychology》2021

Given the perennial challenge of attracting and retaining high-quality teachers, especially in large cities, there is a need to understand why preservice teachers in urban districts choose a teaching career, their perceptions of the profession, and how these relate to their initial career commitments and aspirations. Using latent profile analysis, we examined patterns of motivational perceptions with variables from the Factors Influencing Teacher Choice model alongside perceived task effort cost, opportunity cost, and emotional cost of teaching within a diverse sample of 630 preservice teachers. We identified four distinct profiles that differentially related to theorized antecedents (prior teaching and learning experiences, social encouragement, fallback career) and outcomes (satisfaction, planned persistence, planned professional development, leadership aspirations). Race, gender and certification-level were distributed in unique patterns across profiles. Results provide a holistic perspective of preservice teacher motivations and indicate that perceived costs in relation to FIT Choice variables were a defining characteristic of motivational patterns.  相似文献   

Knowledge-guided multi-granularity GCN for ABSA     

《Information processing & management》2023,60(2):103223

Aspect-based sentiment analysis aims to determine sentiment polarities toward specific aspect terms within the same sentence or document. Most recent studies adopted attention-based neural network models to implicitly connect aspect terms with context words. However, these studies were limited by insufficient interaction between aspect terms and opinion words, leading to poor performance on robustness test sets. In addition, we have found that robustness test sets create new sentences that interfere with the original information of a sentence, which often makes the text too long and leads to the problem of long-distance dependence. Simultaneously, these new sentences produce more non-target aspect terms, misleading the model because of the lack of relevant knowledge guidance. This study proposes a knowledge guided multi-granularity graph convolutional neural network (KMGCN) to solve these problems. The multi-granularity attention mechanism is designed to enhance the interaction between aspect terms and opinion words. To address the long-distance dependence, KMGCN uses a graph convolutional network that relies on a semantic map based on fine-tuning pre-trained models. In particular, KMGCN uses a mask mechanism guided by conceptual knowledge to encounter more aspect terms (including target and non-target aspect terms). Experiments are conducted on 12 SemEval-2014 variant benchmarking datasets, and the results demonstrated the effectiveness of the proposed framework.  相似文献

发展农村服务业拓展农民就业空间的运行机制研究     

沈建红  沈晨仕 《湖州职业技术学院学报》2011,9(2):1-4,8

现代农村服务业是衡量农村社会经济发达程度的重要标志。加快农村服务业发展,是推进农村经济结构调整、转变农村经济发展方式和促进农民就业的有效途径。以浙江省为例,对农村服务业和农民就业问题进行实证研究,在区际差异性分析的基础上,寻求以农民住地就业为主的内部发展方案,具有积极而重要的现实意义,也能对其它区域促进农民就业,实现增收致富,推进“三农”事业和新农村建设发展提供有益借鉴。  相似文献   

基于制度构成要素的公共管理制度创新研究     

许广路 《江苏经贸职业技术学院学报》2011,(4)

公共管理制度体系由正式约束、非正式约束和实施机制组成,公共管理制度创新必须综合考虑这三个要素的特征与功能。现阶段,应高度重视我国公共管理正式约束的创新作用,特别是正式约束的形成机制;应促进非正式制度的变革创新,使之与正式制度变迁相互协调。完善有效的实施机制是制度创新成功的关键。  相似文献
