This article aims to makes a contribution to redressing a methodological and theoretical imbalance in existing research on refugee and asylum‐seeking children. It draws on two qualitative studies from Wales with children and young people. The samples include unaccompanied minors and children living with families as well as both children who are supported in the asylum system and those who have been granted refugee status. The focus on ecological post‐migratory stressors and coping processes that young people identify as being integral to their well‐being and, once granted status, to how they adapt to settlement includes a selective study of some of the sources of resilience referred to in the children's talk. Recognising the interplay between individual and environment leads to a discussion of both personal attributes and collective cultural identities. 相似文献

秦巴山脉重庆片区,旅游业发展相对缓慢,旅游竞争力不强,旅游资源优势未能完全转化为旅游经济优势,旅游扶贫作用尚未充分显现。运用加权求和多指标综合评价模型对该区域旅游竞争力进行评价,秦巴山脉重庆片区旅游竞争力年均增幅超过9%,总体保持较快上升态势,但增长的稳定性较差,内部差异明显。秦巴山脉重庆片区应采取多措并举,持续推进,扬长补短,强力营销,完善旅游公用设施,重视旅游人才队伍建设,营造良好文化环境来增强其旅游竞争力。 相似文献

Given their key role in overall programme quality, it is critical to examine how early childhood programme centre directors in the United States perceive challenging behaviour. Participants completed a survey asking which behaviours they perceive to be most problematic, the number of children dismissed or expelled from the programme during the last year, and the most commonly used strategies for addressing challenging behaviours. Results point to several promising practices and highlight the variability in access to evidence‐based practices based on programme type. Areas that warrant more targeted professional development are discussed, and findings are situated within the larger early childhood context. 相似文献

Estimation in the multivariate context when the number of observations available is less than the number of variables is a classical theoretical problem. In order to ensure estimability, one has to assume certain constraints on the parameters. A method for maximum likelihood estimation under constraints is proposed to solve this problem. Even in the extreme case where only a single multivariate observation is available, this may provide a feasible solution. It simultaneously provides a simple, straightforward methodology to allow for specific structures within and between covariance matrices of several populations. This methodology yields exact maximum likelihood estimates. 相似文献
