传统制造业集群协同演进机制探析——天津自行车集群纵向案例研究

产业集群对区域乃至国家经济发展具有重要的作用,然而产业集群发展过程中的影响因素及其相互作用机制至今仍未得到系统的阐述.从协同演进理论视角,结合组织生态学、制度理论、战略管理理论和社会网络理论等,对天津自行车产业集群的发展历程展开多层次、时间序列的分析,以深入挖掘产业集群发展过程中各种要素的相互作用、协同演进机制,提出产业集群的发展是企业战略、产业环境以及制度环境协同演进的过程,同时集群发展过程中创业者的社会资本发挥重要作用.这种将多维理论视角相结合起来进行分析的方法,有利于更好地理解产业集群的演进机制.     

Pupil mobility in schools and implications for raising achievement

This paper examines the causes of pupil mobility and good practice in schools to address mobility issues. Pupil mobility is defined as ‘a child joining or leaving school at a point other than the normal age at which children start or finish their education at that school’. The first part draws upon evidence of a survey, which explores the views of headteachers on the nature and causes of pupil mobility in schools and the priority they give to addressing pupil mobility issues in their schools. It examines the cause of mobility in schools in the context of mobile groups. This is followed by the challenges for managing mobility and strategies to address pupil mobility in schools. The second part of the paper outlines successful strategies that minimize the effects of mobility in schools. Evidence is drawn from case‐study research and focuses on the school systems, pastoral care and access to learning which combine to support the induction, assessment and monitoring of newly arrived pupils in school and effective use of data for self‐evaluation. Examples of flexible curriculum organization, innovative approaches to additional support and effective administrative procedures are drawn upon. Evidence reflects the views of a range of school staff, parents/carers and pupils in the case‐study school, as well as the judgements of senior researchers. Policy implications for government and for all concerned with school performance are highlighted, as well as many practical suggestions for raising achievement of mobile pupils     

The relative effects of university success courses and individualized interventions for students with learning disabilities

Little is known about the relative effects of post‐secondary learning services for students with learning disabilities. We compared outcomes for students with learning disabilities who selected to: (1) take an academic learning success course (course‐intervention), (2) have regular individual interventions (high‐intervention) or (3) use services only as needed (low‐intervention). Pre‐ and post‐test comparisons revealed improvements in academic self‐efficacy and academic resourcefulness for students in the course‐ and high‐intervention groups. The course‐intervention group also showed decreases in their failure attributions to bad luck and increases in their general repertoire of learned resourcefulness skills in comparison to the high‐intervention group and had significantly higher year‐end GPAs in comparison to the low‐intervention group. Here we find positive outcomes for students with learning disabilities taking a course that teaches post‐secondary learning and academic skills.
