“人以群分”适用于大学生的学业成就吗——基于社会网络分析和Meta分析的方法

嵌入班级网络中的大学生在交往中形成不同的小群体,这些小群体间的学业成就是否具有显著性差异?研究者将社会网络分析方法中的整体网分析与元分析(Meta分析)相结合,在对大学生班级内小群体的学业成就差异进行多项独立研究的基础上,运用元分析技术将29项研究(N=1076)的结果予以综合分析,得到如下结论:(1)每个班级的大学生都在互动过程中形成了不同数量的小群体,且每个小群体中的学生数量不同;(2)大学生学业成就存在着“人以群分”现象,即同一班级的大学生在互动中产生的小群体在学业成就上存在显著性差异。因此,大学生应加强与高学业成就水平的小群体之间的互动以提高学业成就;而高校管理者也应采用科学的方法识别班级中的不同小群体,从而采取相应的学业成就提升策略。     

Does maternal employment influence poor children’s social development?

Various initiatives over the past 40 years have aimed to strengthen children’s early learning and social development. One policy theory—manifest in recent welfare reforms—postulates that requiring single mothers to work more outside the home will advance children’s well-being. We first examine whether young children’s social development is related to maternal employment among 405 women who entered welfare-to-work programs in 1998. For girls, age 24–42 months, we found that their mother’s recent employment duration was significantly associated with a lower incidence of aggressive behavior and inattentiveness, measured by two scales from the Child Behavior Checklist (CBCL 2/3). Yet these relationships with employment were weaker than more robust associations observed for proximal child-rearing practices, including the frequency of reading with the child, enforcing a regular bedtime, the propensity to spank the child, as well as levels of maternal depression. We then assess whether broader measures of the mother’s economic security help to predict these proximal determinants of development. We observed that food security and indicators of job quality consistently predicted the proximal factors. Structural equation models (SEM) provided additional evidence that these broader indicators of economic security, but not recent employment per se, operated through parenting practices and maternal depression to influence girls’ and boys’ social development. These results are consistent with recent findings from random-assignment experiments, showing that employment gains rarely affect child outcomes unless mothers’ income and broader economic security also improve.     

科技奖励对社会创新的影响机理——基于广东的探索性案例分析

对科技奖励作用于社会创新的机理加以研究，认为承认是科技奖励的本质特征，科技奖励以“动机+资源+环境”的模式推动社会创新进程和成果转化：通过承认机制激发科研人员的需求；通过激励机制强化科研人员的创新动机；通过导向机制引导优势资源向重点发展技术领域、产业方向聚集；通过竞争机制筛选优秀科研成果和人才，营造良好的社会创新环境。而在这种模式下取得的经济效益又用于加大科技奖励投入，循环往复地推动社会创新不断发展。以广东省科学技术奖为例研究其对社会创新的作用机制，认为其主要通过控制奖励数量、提高奖金额度、调整奖项结构、提升奖励质量等方式发挥科技奖励的承认、激励导向和竞争作用。在此基础上分析广东省科技奖励体系存在的问题，提出发挥民间力量设奖、规范奖后派生待遇、提高个人奖项权重、加大对青年科学家支持力度等对策建议。

A man on the inside: Unlocking communities as complementary assets

Since Teece's seminal paper explaining who were the gainers from technological innovation, increased globalization and the information and communication technology revolution have brought new ways for firms to organize and appropriate from innovation. A new more open model of innovation suggests that firms can benefit from sources of innovation that stem from outside the firm. The central theme of this paper is how firms try to unlock communities as complementary assets. These communities exist outside firm boundaries beyond ownership or hierarchical control. Because of practices developed by communities to protect their work, firms need to assign individuals to work in these communities in order to gain access to developments and, to an extent, influence the direction of the community. Using network analysis we show that some software firms sponsor individuals to act strategically within a free and open source software (FOSS) community. Firm sponsored individuals interact with more individuals than interact with them, and also they seek to interact with central individuals in the community. However, we can see differences in how individuals interact, depending on whether their affiliation is with a dedicated FOSS firm or an incumbent in the software industry. Apparently, some firm managers believe they need ‘a man on the inside’ to be able to gain access to communities.     

Co-evolution of physical and social technologies in clinical practice: The case of HIV treatments

In this paper, we investigate the interplay of clinical knowledge and technological capabilities in the recent development of HIV/AIDS treatments and offer qualitative and quantitative evidence from the empirical setting of Italian practice. The study contributes to the literature on the co-evolution of physical and social technologies in medical innovation by showing how professional guidelines, systematic evaluative research and local coordination mechanisms contribute actively to the resolution of the uncertainty that surrounds technological advances, while leaving room for largely discretional therapeutic choices. The resulting variety in implementation strategies improves health outcomes, but may reduce productive efficiency.     

Influence of social media on operational efficiency of national scenic spots in china based on three-stage DEA model

An increasing number of national scenic spots around the world use social media, such as micro-blogs and Twitter, to promote their popularity and improve their operational performance. National scenic spots may adopt different social media behaviors that lead to unbalanced operational performance. This study takes the perspective of social media adoption in national scenic spots by looking into the influence of social media adoption behaviors on operational performance based on the three-stage data envelopment analysis model. We found that most of the national scenic spots in China have low pure technical efficiency and that operational performance, including social media popularity and operational performance, is significantly determined by various social media adoption behaviors.     

引文国际化对论文被引的影响研究

[目的/意义]在学术交流日趋国际化的背景下,本文拟探索引文国际化与被引量之间的关系,力图回答良好的国际视野是否有助于提升论文的学术影响力这一学界普遍关注的问题。[研究设计/方法]以社会科学为研究对象,选取管理学、图书情报学和新闻传播学的181,406篇CSSCI论文为研究样本,采用相关分析、非参数检验与回归分析的方法研究引用外文期刊论文的数量、学术质量、学科领域、时效性对论文被引量的影响。[结论/发现]在控制了文献类型、期刊声誉等若干可能影响论文被引量的因素后,发现样本论文的引文国际化水平对其被引量具有显著的正向影响。具体而言,引用外文期刊论文的数量越多、平均学术质量越高、学科专属度越高、平均时效性越强的论文具有更高的被引量。[创新/价值]证实了国际视野有助于提升中文社科论文的学术影响力,并提出了有针对性的建议。
