In the present study the longitudinal relations between quantity of centre-based child care (in months) and teacher reports of internalising and externalising behaviour in the first and second grades were examined for 325 Slovenian children. The socio-political context of affordable, accessible and homogenously high-quality child care is quite different compared to the context in countries from which many child-care studies originate (e.g. the USA). In Slovenia quality standards are regulated (child:staff ratio, teacher education, curriculum), the service is subsidised and children are guaranteed a place after the end of parental leave (i.e. at 11 months). In the described socio-political context a beneficial effect of child care quantity was found for internalising behaviour, while there were negative effects for externalising behaviour. Children who spent more time in child care exhibited less internalising behaviour and more externalising behaviour in the first grade of school, both with small coefficient sizes. Our study shows that even in the context of progressive child care some positive as well as less positive effects of child care participation on child development occur.  相似文献

In the context of social media, users usually post relevant information corresponding to the contents of events mentioned in a Web document. This information posses two important values in that (i) it reflects the content of an event and (ii) it shares hidden topics with sentences in the main document. In this paper, we present a novel model to capture the nature of relationships between document sentences and post information (comments or tweets) in sharing hidden topics for summarization of Web documents by utilizing relevant post information. Unlike previous methods which are usually based on hand-crafted features, our approach ranks document sentences and user posts based on their importance to the topics. The sentence-user-post relation is formulated in a share topic matrix, which presents their mutual reinforcement support. Our proposed matrix co-factorization algorithm computes the score of each document sentence and user post and extracts the top ranked document sentences and comments (or tweets) as a summary. We apply the model to the task of summarization on three datasets in two languages, English and Vietnamese, of social context summarization and also on DUC 2004 (a standard corpus of the traditional summarization task). According to the experimental results, our model significantly outperforms the basic matrix factorization and achieves competitive ROUGE-scores with state-of-the-art methods.  相似文献

Increased activity of multiple stakeholders (e.g. agents and owners) have created new challenges for some coaches working in professional sports clubs. The purpose of this project was to draw attention to the normative or accepted practices inherent in sport work, some of the day-to-day realities of some coaches working in this context, and to understand how coaches’ perceptions of other stakeholders come to bear on their individual circumstances, career expectations/objectives and professional agency. Data were generated from semi-structured interviews with seven professional basketball coaches who worked in top-level European clubs. The analysis reveals the coach’s relationships between some owners and agents differed with respect to exercising professional agency, and, coach’s decisions and actions were tied to their professional ideals as well as understandings of what they need to undertake their work effectively and negotiation and/or adjustment strategies. Occasionally coach’s work practices could be viewed as antithetical to employment security, however, the presence of insecurity was at times embraced and used strategically to affect workers’ career decisions. Amid contemporary regional geo-political shifts, this work aids examinations of global sport settings, structures and issues that may contour sporting professionals’ lives.  相似文献

This study examines the teaching gap between rural and urban schools in China from the perspective of teacher professional learning communities (PLCs). Drawing on in-depth interviews with 36 primary school teachers, the study finds striking disparities between rural and urban schools in the working of Teaching and Research Groups (TRGs). These disparities in TRGs result in divergent patterns of instructional capacity building in rural and urban schools. The evidence shows that teaching and teachers are strongly shaped by the school organizational context. It suggests that strengthening school-wide PLCs is an important way of narrowing the rural-urban teaching and learning gaps.  相似文献

在知识经济时代,学科知识的传播与扩散促进了学科的协同、交叉、融合、发展与创新。文章利用复杂网络算法对学科引证知识扩散时序演化网络进行动态链路预测分析,以期探索学科知识流动结构变化及演进态势,为学科知识管理及决策制定提供可资借鉴的理论和实践参考。文章以学科引证知识扩散时序演化网络结构信息为基础,采用10项基于局部信息的相似性指标分别对无权和加权知识扩散网络进行动态链路预测分析,并将各指标的预测性能进行了对比。最后,利用无权RA指标和加权AA指标对学科引证知识扩散态势进行了预测。研究表明:不同指标的预测精度在不同的时间段内会动态变化;在学科引证知识扩散网络中,存在一定程度的弱连接效应;不同链路预测指标在无权和加权学科引证知识扩散网络中的适用性存在一定差异。  相似文献

20世纪分析美学家维特根斯坦在形而上学危机及哲学的语言学转向的背景下率先从图像论、语言误用和家族相似等几个方面给关的本质以彻底的解构,因而使其理论具有很大的后现代色彩,与其后来的解构主义美学有异曲同工之妙,在西方美学史上具有巨大的理论开创性。  相似文献

文章从关联理论的角度研究言语幽默,它对幽默话语具有极强的解释力。幽默是说话人表达信息时在恪守最佳关联原则和"关联理论"为会话幽默的推导下所提供的理解模式,妙语语境效果小,关联性小,是言语幽默效果产生及理解的关键。  相似文献
