In this article we examine the complex relationship between care experience, mental health and exclusion from school and how young people (YP) negotiate these different experiences and identities. The study is a secondary analysis, informed by symbolic interactionist theory, of interviews conducted with 19 care experienced YP in Scotland. Not all of the YP were excluded and not all had a formal mental health diagnosis, as such our study design allows interrogation of the contexts and relationships which not only facilitate but also disrupt pathways to exclusion. It also allows reconsideration of assumptions of vulnerability which are often applied to care experienced YP. Our findings suggest that these YP are moving beyond ‘role playing’ the identities ascribed to them and actively seek out relationships which enable them to construct alternative identities. 相似文献

Abstract Supporting global health priorities through the development of robust health science librarianship partnerships is of significant importance. Increased demand for synthesizing evidence-based information, collating quality resources, and increasing research productivity to improve human health requires integration of library and information science skills and expertise. The Health Sciences Library (HSL) at the University of North Carolina at Chapel Hill (UNC), exists to be an indispensable partner in health information and knowledge, teaching and learning, and research. As global efforts at UNC expanded, the HSL sought to ensure that our global engagement strategy and integration were aligned with campus priorities and partner needs. The HSL created a global research partnership plan: identify resources that improve efficiency, increase access to information, build in-country capacity and expertise—all while strengthening collaborations across multiple countries. Creating a meaningful and sustainable engagement strategy was central to envisioning our path forward and can be used as a framework for consideration by librarians in similar settings. 相似文献

在线健康社区用户个人健康信息管理行为特征研究 总被引:3,自引:1,他引:2
[目的/意义] 旨在对在线健康社区用户的个人健康信息管理行为特征进行分析,并在此基础上,对"平台-PHIM-健康目标"这一模式中的元素之间的关系进行探讨。[方法/过程] 选择患有红斑狼疮的在线健康社区用户作为调查对象。采用聚类方法对个人健康信息管理行为的总体测度水平不同的群体进行识别;利用单因素方差分析(One-way ANOVA)对不同群组进行比较研究。[结果/结论] 将依托在线健康社区进行的个人健康信息管理行为界定为健康信息发现、健康信息互动和健康信息分享。从数据分析结果来看,首先,在线健康社区的红斑狼疮患者在个人健康信息管理行为水平上存在显著的高低差异。第二,用户所感知到的社会支持与其个人健康信息管理水平存在正相关关系。第三,个人健康信息管理与用户健康目标之间存在正相关关系。本研究为在线健康社区完善其服务方式,促进慢性病人个人健康信息管理水平提高提供合理建议。 相似文献

[目的/意义]研究方法在学术研究中发挥着至关重要的作用。确认图书馆情报学领域主要的研究方法,并对它们进行了解熟悉,以在开展研究时能合理选择、灵活使用,确保研究质量。[方法/过程]对近2 000篇图书馆情报学领域的研究文献以及相关研究方法论文进行内容分析,在此基础上对研究方法的类分命名、图书馆情报学界主要的研究方法的确定、特点和使用注意事项进行介绍和讨论。[结果/结论]研究方法应以数据收集法而不是数据分析法命名。图书馆情报学领域常用的研究方法包括实验法、问卷法、理论研讨法、内容分析法、访谈法和书目计量法,每种方法都有各自的特点。因而在选择使用时,既应根据具体研究课题及研究方法之特性,也要考虑使用注意事项,并尽量在同一研究中采用两种或更多的方法,以扬长避短,更有效地展开研究。 相似文献

This research explored how seven primary school teaching assistants (TAs) experienced their role in supporting children's mental health. Interviews were analysed using Interpretative Phenomenological Analysis (IPA). The participants believed that they supported children's mental health and particularly referenced the close relationships that they formed with children. Throughout their accounts of supporting children, the TAs referenced helpful factors (e.g. support from other staff) and challenges (e.g. hierarchy) within the school system. Supporting children’s mental health was an emotional experience for the TAs; they discussed the rewarding element, however, the topic also elicited fear. The findings provide several implications for school staff and external professionals about how TAs can be supported in their role. These include involving TAs in training opportunities, providing TAs with supervision, considering communication systems in schools, and introducing a mental health policy. 相似文献

青少年体育健康问题上升国家战略高度。“青少年体育健康公共服务”是一个在青少年体育领域内,由“体育健康”和“体育公共服务”综合而成的全新概念,学界还未深入探讨与挖掘。充分结合“健康管理”理论,基于对“青少年体育健康”和“体育公共服务”相关研究文献的回顾,归纳“青少年体育健康公共服务”内涵与特征。概念特征包括:“学校体育”“青少年体育俱乐部”是核心供给主体;健康医疗等事业、非营利性机构是重要支撑;始终强调青少年受众被动接受“体育健康促进”与主动应用“体育健康素养”相结合;供给产品具有“纯公共物品”性质,公共财政补贴是解决公共服务资源配置矛盾关键方式;“互联网虚拟社区”是实现多元主体协同供给的技术基础与激励条件。最后,基于概念属性展望“青少年体育健康公共服务”的未来研究趋势,包括:开发“运动干预”“心理调试”和“营养膳食”三维评估指标体系;完善“学校”“社区”“医疗部门”“健康管理机构”和“家庭”的协同供给机制;深度开发“青少年体育俱乐部”和“青少年联赛体系”营造“体育健康素养培育”空间;实现“青少年体育健康公共服务”均等化局限,以及加快“青少年体育健康公共服务”互联网平台建设,破解公共服务资源闲置问题。 相似文献

This formative, outcome-oriented, theory-based evaluation research study assessed the effectiveness of requiring an international (‘I’) course by measuring students’ intercultural sensitivity (IS) at the start and end of a semester. Findings revealed that students’ IS scores did not change regardless of the type of class in which the student was enrolled and were not significantly different based on gender, age, ethnicity, undergraduate classification, or number of ‘I’ courses taken. There were significant differences in IS based on religion, traveling outside the US, participating in a study abroad course, and the number of cultural events in which the student had participated. Regression analysis confirmed that religious affiliation and number of times traveled outside the US were significant predictors of IS. This study is an example of the use of theory-based evaluation in an educational system and provides important insights into what experiences affect college students’ IS. 相似文献

BackgroundSon preference is an enduring phenomenon in China and may often be related to childhood adverse experiences. According to a life-course perspective, adverse experiences during a childhood period may have a long-term effect on mental health in later age. However, little is known about this relationship between parents’ son preference, childhood adverse experiences and adulthood mental health in China.ObjectiveThe study aims to evaluate the association of parents’ son preference and individual mental health in old age in China. The mediating role of childhood adverse experiences was also estimated.Participants and settingThe China Health and Retirement Longitudinal Study (CHARLS) 2015 combined with CHARLS life history survey was analyzed (N = 11,666).MethodsMental health was measured by a shortened modification of the Center for Epidemiologic Studies Depression scale including seven items, and higher scores indicated worse mental health status. A four-step mediating model was applied.ResultsRespondents growing in families with son preference had on average 0.75 (P < 0.001) points higher on the mental health scale than their counterparts, and the effects were consistent for both males and females. Childhood adverse experiences measured by physical maltreatment, emotional adverse experiences and witnesses of inter-parent violence mediated the relationship between parents’ son preference and individual adulthood mental health by 47.87%. For females, physical maltreatment and emotional adverse experiences explained the most parts of health effects of parents’ son preference, whereas witnesses of inter-parent violence was the most influential mediator for males.ConclusionParents’ son preference led to adverse childhood experiences, which influenced mental health in adulthood. 相似文献
