网络密度、高管注意力配置与企业绿色创新:制度压力的调节作用

本文整合社会网络理论、注意力基础观和新制度主义理论等,通过对282家制造企业的问卷调查,采用多元回归分析方法,探讨了网络密度和高管注意力配置的交互匹配对企业绿色创新的影响机制,以及制度压力在其中的调节作用。研究发现,在高密度网络中,高管采用注意力聚集策略对绿色创新有显著正向影响;而在低密度网络中,高管采用注意力分散策略对绿色创新有显著正向影响。规制压力和模仿压力均正向调节网络密度和高管注意力配置的交互作用对绿色创新的影响,但模仿压力的调节作用更强。通过构建不同制度压力情景下网络密度与高管注意力的交互作用对绿色创新影响的理论框架,本文推动社会网络理论、注意力基础观等成熟的理论成果从一般创新向绿色创新研究领域繁衍,为企业绿色创新加入与主流理论的对话做了努力,为企业在绿色创新过程中根据不同的制度压力,以及所嵌入的组织间网络密度情况,选择合适的注意力配置策略提供理论参考。     

加拿大不列颠哥伦比亚省基于大概念的幼小衔接课程框架及启示——以数学课程框架为例

加拿大不列颠哥伦比亚省的幼小衔接课程框架得益于大概念的统摄。以数学课程为例,对其幼小衔接课程框架进行分析,得到四点启示:幼小衔接课程的开发先要基于全局审视确认其对于立德树人、学生发展核心素养的价值意蕴;幼小衔接课程的纵向衔接要基于课程逻辑提炼大概念,保持综合课程、分科课程间的适度张力;幼小衔接课程的横向落实要基于教与学逻辑,围绕大概念构建知识、能力、传统文化等的学习标准与教学指导纲要;幼小衔接课程的持续完善要基于教育质量监测及时检验幼小衔接成效,为其修订提供决策依据。

Intergenerational Mobility Modes and Changes in Social Class in Contemporary China

Using data from three China General Social Surveys, this paper analyzes changes in the basic situation of intergenerational mobility among social classes in China over the past 60 years. General social mobility was found to have increased, but social openness tended to show a wave-like pattern of change. Despite this, intergenerational inheritance was the main form of intergenerational mobility in every period. With the transformation of the socioeconomic system, the main mechanism of social exclusion changed from “systemic exclusion” to “market exclusion,” leading to changes in the structure of social opportunity. As a result, the form taken by intergenerational mobility varied significantly. This is chiefly evident in the gradual decline in the dominance of intergenerational inheritance among particular strata, with cross-class cyclical mobility becoming more difficult. On the one hand, changes in the social exclusion mechanism may increase social openness, making society more dynamic and strengthening social legitimacy. On the other hand, as the dominant class learns how to use market exclusion to achieve class reproduction, class solidification may still be possible in a future Chinese society.     

Qualitative exploration of supporting figures in the lives of emerging adults who left care compared with their noncare‐leaving peers

Studies on youth leaving care have emphasized their limited social support and their need for continuing support after emancipation. However, less is known about the nature of their existing social networks after emancipation and their roles during their transition to adulthood compared with their noncare‐leaving peers. With this in mind, 32 young adults aged 18 to 25 participated in semi‐structured interviews regarding their current support figures in order to learn whether they were congruent with their needs after emancipation. Thematic analysis revealed four main features of the two groups' social networks: (a) stability versus uncertainty as to the lasting presence of the supportive figure, (b) reliance on parents as main supportive figures versus relying on different supportive figures, (c) confidence versus uncertainty in the supportive figures' ability to help, and (d) holistic versus fragmented support of the young adults' needs. The discussion addresses the unique characteristics of care leavers in emerging adulthood and the implications of their social networks' features for their adjustment after emancipation. One of the study's recommendations is to proactively connect them to new supportive figures such as professionals or mentors by offering them mentoring programs cognizant of the instrumental and developmental tasks of emerging adulthood.     

Beyond the Preschool Years: Children’s Perceptions About Starting Kindergarten

This article describes a research study that investigated three‐ and four‐year‐old Canadian preschool children’s perceptions about starting kindergarten. Findings from 33 focus‐group discussions suggest that children begin to formulate ideas about starting kindergarten prior to school entry. Children’s responses were grouped according to three themes, play versus academic activities and homework; getting bigger but still needing help; and rules. Overall, the responses highlighted their expectations regarding continuity and discontinuity between the two environments. These findings support the position that children should be given the opportunity to contribute to the planning of transition practices.

Father's Migration and Leaving the Parental Home in Rural Mozambique

Migration is an increasingly common global phenomenon and has important implications for the well‐being of family members left behind. Although extensive research has examined the impact of parental labor migration on school‐age children, less is known about its effect on adolescents. In this study, the authors used longitudinal survey data collected in rural Mozambique (N = 515) to assess the association between father's migration and adolescent children's leaving the parental home, an important component of the transition to adulthood. The results showed that father's migration delays home‐leaving for adolescent girls and that these effects are not mediated by school enrollment. The results for boys were inconclusive. The authors also found that remittances and longer durations of paternal migration were negatively associated with the transition out of the home. On the basis of the findings, they argue that father's migration delays girls' marriage.     

Green supply chain management: the case of the construction sector in the United Arab Emirates (UAE)

Restraining the negative environmental impacts of the construction sector constitutes one of the major challenges of the twenty-first century. However, efforts to address it have been largely fragmented. With environmental consequences of a construction project typically dispersed across its life cycle, i.e. from design through to end-of-life, greening this sector requires a supply chain wide focus inclusive of all key stages and stakeholders; also, all relevant aspects such as the nature of green practices implemented and associated drivers, barriers and performance implications need to be considered. This forms the focus of the present study where a comprehensive, green supply chain management oriented understanding of the construction sector is developed through the context of the UAE construction sector, and incorporating inputs from all key stakeholders, i.e. Developers, Architects/Consultants, Contractors and (material) Suppliers. The study contributes to improving the efficiency and effectiveness of greening of the construction sector.
