基于知识图谱的我国公共体育服务研究可视化分析     

易军 《吉林体育学院学报》2020,(1):21-29

以中国知网所收录的2007年至2017间核心期刊中有关公共体育服务文献题录作为分析数据样本,对所搜集到的254篇文献进行可视化分析。借助CiteSpace V软件,运用文献计量学方法与内容分析方法,结果表明:近十年我国公共体育服务研究经历了波浪式增长与急速增长两个阶段,研究主题紧密结合国家政策战略,在不断调整中推动了公共体育服务的发展。主要特征体现在始终服务于国家宏观政策方针,顺应了政府职能转变下对体育发展改革的时代需求;以“体育管理、公共服务”为核心的研究主题始终贯穿,主动融入政策响应的研究诉求强烈,人民美好生活中体育需求的关照不足;整个研究过程充满了动态性与局限性。未来研究应坚持与国家公共服务政策相伴相生,形成开放性反馈研究系统;注重公共体育服务研究的政策引领和政策的事后绩效评估;打造学术共同体,提升公共体育服务研究成果在政策咨询和智库建设中的作用。  相似文献   

一种在轨海上多运动舰船目标检测和跟踪方法     

矫腾章  胡玉新  吕鹏  张凯  台宪青 《中国科学院大学学报》2020,37(3):368-378

传统遥感卫星图像处理采用在地面进行目标检测和跟踪处理的模式，卫星将拍摄到的图像数据下传至地面数据处理中心，由地面数据处理系统对接收到的遥感图像数据进行目标检测和跟踪。然而，随着遥感图像分辨率的不断提高，需要下传的数据量增大，导致星地数据传输的时间大大增加，最终造成目标检测和跟踪的时效性降低。针对上述问题，提出一种基于多特征量判别的Canny边缘检测和联合概率数据关联的在轨海上多运动舰船目标检测和跟踪方法。将该方法利用中国科学院微小卫星创新研究院的高分微纳卫星实测数据在模拟星载的嵌入式开发平台上进行验证，结果表明该方法能够在轨对海上多运动舰船目标进行快速、准确的检测和跟踪。  相似文献

Methods for assessing higher education research team collaboration: comparing research outputs and participant perceptions across four collaborative research teams     

Nick Kelly  Joanne Doyle  Marisa Parker 《高等教育研究与发展》2020,39(2):215-229

ABSTRACT

This article suggests that situations in which multiple research teams are convened under similar conditions present an opportunity to discover factors that lead to productive collaboration. It argues that social network analysis of research team outputs becomes more valuable when paired with data about research participant perceptions; and that any variables used as indicators of collaboration need to be calibrated using datasets from multiple studies with cross-team comparisons. The article provides an example of the kind of methodology needed to achieve this, describing a study with data from four research teams based at an Australian university campus, reporting their research performance over four years under conditions in which many variables were controlled and with results augmented by a survey of participant perceptions. Findings from the study indicate that there were exceptions to hypothesized associations between participant perceptions of collaboration and specific social network analysis measures over co-authorship data. The article suggests that, given the methodological challenges of studying research teams in the field, multiple datasets combining findings such as those in the present study are a path towards the development of indicators of productive higher education research collaboration.  相似文献   

Can social integration in schools be mandated: Evidence from the Right to Education Act in India     

《International Journal of Educational Development》2020

Although Affirmative Action policies have been enforced in many countries, their consequences are highly understudied, especially in the context of developing economies. Section 12(1)(c) of the Right to Education (RTE) Act enforced in 2009 is the first attempt to introduce affirmative action in primary schools in India. The act requires all private schools to reserve at least twenty five percent seats for children from economically weaker sections. To understand the effect of the act on i) social integration and ii) academic outcomes, we asked 1500 children (grades one to three) from four schools to answer friendship surveys and short tests in Mathematics and English. The schools in our sample vary considerably in constitution and were intentionally chosen to understand the impact of the act in different school settings. The friendship surveys show strong homophily i.e. non-RTE students cite other non-RTE students as friends, while RTE students chose to be friends primarily with other RTE students. Trends in test scores reveal that students admitted under the RTE quota score significantly lower than non-RTE students. However, RTE students who have a higher share of non-RTE friends have better test scores, suggesting that affirmative action may have a positive influence on learning outcomes for RTE children. Further we note that commitment from the school authorities and systematic monitoring and evaluation of the implementation of the act will go a long way in bringing out some of the benefits that this act was designed to achieve. Our findings have important policy implications with respect to ensuring proper implementation of the Section12(1)(c) of the RTE act in schools across the country.  相似文献   

Special educational needs and inclusion,moving forward but standing still? A critical reframing of some key issues     

Alan Hodkinson 《British Journal of Special Education》2020,47(3):308-328

This article draws together my thinking in relation to special educational needs and inclusion that have dominated my practice. The article, through the concept of embodiment, revisits, reviews and reframes the key issues of the construction of special educational needs, inclusion and the ideology that binds them together. Through this exploration, I argue we often seem to move forward with policy while in reality standing still in ensuring the ‘success’ of all of our pupils. By critiquing and reframing taken‐for‐granted assumptions and the sacred words ‘success’ and ‘achievement’, this article maps out the future directions of inclusive education. It concludes with a reflection on my first days as a ‘teacher of special educational needs’ and my work to support Kenny, a student with cerebral palsy. This personal reflection maps out a different form of educational success that perhaps could provide a forward momentum to develop more successful inclusive education policy and practice.  相似文献
