School exclusion,substance misuse and use of weapons: an interpretative phenomenological analysis of interviews with children     

Sarah Martin-Denham 《Support for Learning》2021,36(4):532-554

The study presents data drawn from semi-structured interviews with five young people permanently excluded from schools in North East England. The research aimed to investigate the risk factors that lead to the children using illegal drugs, to determine the drivers and implications for drug misuse and the carrying of knives into school. The research also hoped to elicit from the young people, the solutions that could have prevented their exclusion from school. The interviews were analysed using interpretative phenomenological analysis to understand how a homogenous sample made sense of their lived experiences. The findings highlight the importance of prompt identification and support for children with learning and subsequent mental health needs as the evidence suggests they lead to perceived negative behaviours by teachers. The research provides further evidence that behaviour sanctions in mainstream schools such as detention and isolation booths do not improve behaviour but make it worse. Original to this research is the finding that children are consuming drugs before school to cope with their inability to access the learning, to aid their concentration and to medicate themselves to reduce the likelihood of being sanctioned by teachers.  相似文献   

知识找回场景下推荐系统模拟实现及评价研究     

程秀峰  张孜铭  孟亚琪  范晓莹  杨金庆 《图书情报工作》2019,63(16):72-83

[目的/意义]信息过载一直是知识工作者在搜集、处理和创造知识的过程中所面临的主要困境。这种困境导致的结果之一是很难回忆起曾经使用过的文档的内容细节及具体位置，而推荐系统则能减少这样的困难。通过研究对比不同推荐系统在这一任务下的优缺点，可以帮助知识工作者更好地完成回忆任务。[方法/过程]基于相关理论，在同一场景（知识找回）模拟实现并测试了4种不同类型的推荐过程，包括基于内容的推荐CBR、基于协同过滤的推荐CFR、基于推理网络的推荐INR与融入了情境感知的推荐CAS，根据所确定的若干指标（精确性、情境相关性、预测性、多样性）对推荐效果进行比较。[结果/结论]结果显示，以上推荐系统在帮助用户回忆并找回文档过程中都有各自的优势，而基于情境感知的推荐系统在情境相关性与预测用户行为方面具有较好的效果。  相似文献

[目的/意义] 为更好地提升基于内容的引文分析效果，对国内外引用对象相关研究进行调研总结，为引用内容分析研究提供借鉴。[方法/过程] 通过调研国内外引用对象相关研究，梳理引用对象的概念定义、分类体系、应用领域和自动化识别等方面研究进展，总结当前引用对象研究不足并提出未来发展方向。[结果/结论] 引用对象从语义层面评价文献学术研究的贡献和利用价值，为引文分析方法增加了重要维度。引用对象研究需要从理论、技术和应用三个方向进行深化：理论上，加强多维度引用对象特征的研究和分析；技术上，探索基于大规模语料的自动化识别方法；应用上，尝试基于引用对象的科研评价服务。  相似文献   

Reputation in the fifteenth century credit market; some tales from the ecclesiastical courts of York     

Hannah Robb 《Cultural and Social History》2018,15(3):297-313

This article explores the language used to defend reputation in instances of defamation, debt and theft presented before the ecclesiastical courts of the Archbishopric of York in the latter part of the medieval period. Finding a circulating language of trust and household credibility in the court papers, the argument concludes that the commodification of reputation was not a phenomenon brought about by the Reformation but that a reputation mechanism was intrinsic to the medieval market embedded in informal institutions, social norms and cultural dictates and enforced in the courts.  相似文献   

视力康复背景下体育锻炼与儿童动态视力关系研究及启示          下载免费PDF全文

潘景玲  蔡赓  殷荣宾  孙雷  王国祥 《体育科研》2019,(1):90-95

目的：探讨动态视力在不同类型体育项目间的发展特征，为体育锻炼改善视力的应用研究提供依据。方法：选取6~10岁无专门体育训练经历的在校学生和参加足球、乒乓球、跆拳道、空手道、游泳、体操等项目的俱乐部或体校学生，共603名。使用动态视力检测仪和标准对数视力灯箱测量动态视力和静态视力。计算动静比（动态视力/静态视力），并将其作为衡量动态视力发展水平的指标。结果：6~7岁是动态视力发展的敏感期（P＜0.05），8岁、10岁男性儿童的动静比高于女性儿童，且差异有统计学意义（P＜0.05）。校外体育练习组的动静比高于普通在校学生组（P＜0.05），开放性运动项目的动静比高于闭锁性运动项目（P＜0.05）。结论：参加体育锻炼对动态视力的发展有积极的影响，且不同运动项目的影响效果不同。  相似文献

Challenging knowledge monopoly in education in the U.S. through democratizing knowledge production and dissemination     

Eunsook Hong 《Educational Action Research》2019,27(1):125-143

ABSTRACT

We discuss democratizing knowledge production and dissemination in education illustrated in two parts that challenge the current knowledge monopoly. Our discourse includes (a) problematic cultivation of the status quo in the hierarchy of knowledge value in the U.S. as a component of civic illiteracy and (b) the need for more evidence through developing practice-based research evidence as a counter to the fixation with evidence-based practice in education. We point out a cultivated state of complacency with regard to the societal expectations of the roles of educational practitioners in the U.S. and discuss developing a new status of practitioner research for knowledge democracy. A virtual space for mentoring practitioner researchers with a goal to help them produce and disseminate their research was included as an example of knowledge democracy.  相似文献   

Promoting a participatory convergence in a Spanish context: an inter-university action research project using visual narrative     

Elia Fernández-Díaz  Carlos Rodríguez-Hoyos  Adelina Calvo Salvador  Gloria Braga Blanco  Lorea Fernández-Olaskoaga  Prudencia Gutiérrez-Esteban 《Educational Action Research》2019,27(3):362-378

ABSTRACT

This article focuses on the deconstruction of an inter-university action research project that has allowed us to rethink our teaching and research, questioning the social, political and ethical dimensions of the university. Following the pre-assembly proposal to promote participatory convergence, organized within the framework of the 1^st Global Assembly for Knowledge Democracy (2017), an action research process was implemented in order to generate systematic inquiry around the current situation of the university and the need to act and rethink our commitment to promoting changes in this context. We have reflected on the meaning of democratization, rethinking the pedagogical relationship with our students and how we critically commit them to promote activism. We generated an environment where we look for the meaning of our practices by means of a visual narrative which has enabled us to weave and identify our own biography and become aware of where we are and why we act in one way or another. We have also focused on the search for the meaning of our actions in relation to the community we belong to and how to deal with the challenges of social justice, encouraging collaboration with other networks in a wider inter-university framework.  相似文献
