重庆市制造业的绿色经济增长核算:2001—2010

基于生产前沿理论的绿色经济增长核算模型,不仅将技术无效率和环境代价纳入了分析框架,而且还与"物质平衡思路"一致;该模型将绿色经济增长的源泉分解为环境约束下的技术进步、技术效率变化和资本深化3大部分。对重庆市27个制造行业的经验分析结论表明:经济增长中普遍存在着技术无效率现象,但50%以上行业的技术效率都得到了改善或维持不变;资本深化是经济增长的主要源泉,而技术进步主导的全要素生产率变动在其中的贡献相对较小;技术进步是引致全要素生产率增长的主要原因。为充分发挥重庆市制造业可持续发展潜力,后续发展中必须转变经济发展方式,在环境约束下走技术进步和技术效率改善的绿色全要素生产率增长之路。     

服务质量和感知价值对服务忠诚的影响——基于餐饮业和细分维度的探索

以餐饮业为调研对象,用结构方程方法探索服务质量和感知价值的细分维度对服务忠诚的影响。研究表明:服务质量的各细分维度对于服务忠诚的影响大多都是通过顾客感知价值的各个细分维度作中介来实现的,对服务忠诚具有直接影响的服务质量因素只有安全性因素;服务质量的移情性维度对感知价值的各维度均具显著影响,有形性维度对感知价值的价格、质量和社会维度具有积极的影响,可靠性维度与感知价值的情感维度相关,响应性维度与感知价值的情感和质量维度相关;感知价值除质量维度外,社会、情感、价格维度均对服务忠诚具有显著影响。因此,餐饮业企业应特别重视服务人员与顾客进行良好的人际互动,促进与顾客的情感交流,把向顾客提供高价值的服务作为提升服务忠诚的有效途径。     

政府规制与中国稀土产品出口增长的二元边际?--对2001-2012年微观贸易数据的实证分析

采用HS?6位数级微观贸易数据,计算2001—2012年中国稀土产品出口增长的二元边际,并进一步分析相对出口规制程度、相对产量与出口增长二元边际之间的相互影响,结果表明：中国稀土产品出口规制政策对稀土产品出口增长的集约边际和扩展边际都有促进作用,其中对集约边际的影响更大;而相对产量对二元边际有负面影响。在中国经济新常态下,随着稀土产品出口规制政策的逐步弱化,应加强对稀土产业的生产规制,提高产品附加值,实现从规模速度型粗放增长向质量效率型集约增长的转变;并积极开拓新的出口市场,促进稀土产业的良性扩张。     

The relationship between classroom quality and students’ engagement in secondary school

Student engagement has been identified as an influential mediator between classroom interactional quality and adolescent learning outcomes. This study examined the relationship between classroom quality and student behavioural engagement in secondary school classrooms. Three dimensions of classroom quality (emotional, organisational and instructional support) and the dimension of student engagement were observed in nine classrooms using the Classroom Assessment Scoring System. Self-ratings of behavioural engagement were provided by 181 Finnish secondary school students along with their teachers’ ratings of classroom-level student engagement. The results showed, first, that there was variation in both classroom quality and student behavioural engagement between the classrooms. Second, classroom organisational support was associated with observed and with teacher- and student-rated engagement, and instructional support was associated with student-rated and observed engagement. Third, emotional support did not have a direct effect on student engagement but contributed to student engagement indirectly via organisational and instructional support. There were no gender differences with respect to self-reported engagement. Class size had a positive effect on teacher-rated engagement. The results demonstrated specific associations between the domains of classroom quality and student behavioural engagement in secondary school classrooms.     

An approach to web-based Personal Health Records filtering using fuzzy prototypes and data quality criteria

Nowadays, new ways of managing and accessing to health-care information are continuously appearing. Web-based Personal Health Records (web PHRs) have the potential to make data about health-care available to clinicians, researchers and students in different medical contexts and applications. Therefore, the amount of web PHRs accessible through Internet has grown enormously and as a result health-care professionals are currently burdened with more and more data. It’s probable that these data, unfortunately, have not always the adequate levels of quality, making that their work cannot always be as successful as expected. As a way of alleviating this fact, the present work is focused on improving the document filtering results in the context of web PHRs management. To achieve this goal, a new kind of document filtering model is proposed. This model is based on fuzzy prototypes which are defined by means of conceptual prototypes. These prototypes are obtained by using a data quality analysis of documents. This analysis guarantees that filtered information will be relevant enough for the information user. The complete model provides an efficient strategy of document filtering that can be very useful when it is necessary to deal with a constant flow of new information.

The Effects of Teacher Professional Development on Children’s Attendance in Preschool

Abstract

Student absenteeism is a widespread and critical issue in early childhood education. Current efforts to reduce student absenteeism in both preschool and K–12 settings have largely been family- and parent-focused interventions. Yet, interventions targeting teachers and schools may similarly be effective tools to improve student attendance. We utilize data from a large-scale, experimental evaluation of an early childhood professional development intervention to examine whether it impacted children’s absenteeism and chronic absenteeism. Although the professional development targeted the quality of teacher-child interactions and did not target children’s absenteeism, we find that the professional development reduced student absence rates by 1.0 percentage points (equivalent to approximately an additional 1.9?days of preschool). The professional development also reduced chronic absenteeism by 6.0 percentage points. Impacts were concentrated among lower-income children. Implications for policies targeting student absenteeism in preschool settings are discussed.
