金代泰山文士交游考     

聂立申 《江西师范大学学报(哲学社会科学版)》2015,(3)

金代泰山及周边地区文化昌达,涌现出大量文人学士。这些文士依籍贯和活动区域不同可大致划分为本地型、周边型和活动型三大类。通过诗酒酬唱、畅游山林、臧否人物等方式,泰山文士构筑了广泛的社会交往网络;与女真贵族、外地文士、道教人士的交往拓展了泰山文士社交网络的空间。泰山文士交游网络的构建与拓展不仅有利于北方各地区的民族融合与社会信息交流对于传承并发展泰山文化亦有重要作用。  相似文献   

Social capital in the classroom: a study of in-class social capital and school adjustment     

Ronan Van Rossem  Marjolijn Vermande  Beate Völker  Chris Baerveldt 《British Journal of Sociology of Education》2015,36(5):669-688

Social capital is generally considered beneficial for students’ school adjustment. This paper argues that social relationships among pupils generate social capital at both the individual and the class levels, and that each has its unique effect on pupils’ performance and well-being. The sample in this study consists of 1036 children in 60 first-grade classes in 46 Dutch elementary schools. Multilevel regression results show that a substantial proportion of the variance in school adjustment can be attributed to the class level and that both individual-level and classroom-level social capital have substantial effects on school adjustment. At the individual level, the size of one’s network is more important than its structure. At the collective level, social capital also has a ‘dark side’ because it can have negative effects on adjustment, lowering the academic performance in a class.  相似文献   

Significant networks and meaningful conversations observed in the first-round applicants for the Teachers’ Academy at a research-intensive university     

Eeva Pyörälä  Laura Hirsto  Auli Toom  Liisa Myyry  Sari Lindblom-Ylänne 《International Journal for Academic Development》2015,20(2):150-162

The University of Helsinki established a Teachers’ Academy to reward excellence in teaching. This study focuses on teachers’ significant networks and their meaningful conversations about teaching and learning before the establishment of the Teachers’ Academy. The research data consisted of answers to open-ended questions, and were examined using social network analysis. The teachers’ network consisted of significant relations with (1) colleagues and other teachers, (2) peers in pedagogical courses and pedagogical experts, (3) students, and (4) family members and friends. The conversations with different parties varied in nature, content and the level of confidentiality.  相似文献   

Conditions for mental health in education: Towards relational practice     

Tom Billington  Sarah Gibson  Penny Fogg  Jamal Lahmar  Harriet Cameron 《British Educational Research Journal》2022,48(1):95-119

There are concerns globally about the emotional wellbeing and mental health of young people and in this paper a critical orientation comprises both theoretical and empirical data sources. The case is made that (1) the medical model of mental health – that of problem identification, diagnosis and medical treatment at the level of the individual – is not appropriate for the vast majority of children and young people in schools and (2) relational approaches would be more sensitive in responding to the complexity of the ‘conditions’ in the schools, homes and communities in which young people live. Articulations of these conditions in the literature are explored while we also draw on empirical data from part of an evaluation of a school-based teacher-training programme in which interviewees and respondents mapped out their own conditions for emotional wellbeing and mental health. We conclude with proposals for relational approaches which (1) acknowledge the links between affect, cognition and school climate and culture, (2) foreground mental health and poverty as impacting on young people’s emotional wellbeing in their communities, families and schools and (3) attend to voice – providing spaces in which young people can develop their own ‘preferred narratives’ concerning emotional wellbeing and mental health.  相似文献   

Unpacking (un)conscious social class bias in faculty hiring processes in Chile: PhD prestige granting university and network     

Roxana Chiappa 《Higher Education Quarterly》2023,77(4):756-773

Social class of origin is apparently an imperceptible attribute among doctorate holders seeking academic jobs. Yet, recent studies in different countries reveal that social class of origin may still be influencing the chances of PhD holders from low social class being hired at prestigious universities. Drawing from the theory of social and cultural reproduction, normative ‘fair’ academic hirings frameworks, and qualitative evidence collected in Chile, this research identifies the mechanisms that trigger (un)conscious social class bias in the stages of recruitment and selection of candidates in seven academic departments in economics and industrial engineering (46 interviews). Findings did not prove explicit classism manifestations, but practices of inclusion/exclusion of candidates based on the prestige of PhD-granting universities, and networks. These reproduce the relationship between social class and unequal chances of being connected to prestigious universities. Recommendations to address (un)conscious social class bias in academic hiring are discussed.  相似文献   

What Tahrir Square Has Done for Social Media: A 2012 Snapshot in the Struggle for Political Power in Egypt     

Ramesh Srinivasan 《The Information Society》2014,30(1):71-80

While the debate rages on the role of social media technologies in the initial days of the Egyptian revolution of 2011, a more relevant research question today is the role of social media within an increasingly contested and turbulent political sphere. This article identifies three key modes by which social media is being exploited to impact political power, and uncovers the salience of each of these through 2 years of multisited ethnographies and interviews. First, I argue that political actors across the political spectrum, from liberals to Muslim Brotherhood (Ikhwan), are using technologies to build wider ranging, heterogeneous, and diverse networks of supporters, expanding their base from a more historically homogeneous core support group. Second, I argue that actors are working to build bridges between older and newer media platforms, recognizing that each platform is increasingly being shaped by the other. Finally, I describe some of the ways that technology is being used by activists to subvert their competition, promoting campaigns of misinformation and hacking at the expense of others.  相似文献   

Creating value in ecosystems: Crossing the chasm between knowledge and business ecosystems   总被引：1，自引：0，他引：1  

Bart Clarysse  Mike Wright  Johan Bruneel  Aarti Mahajan 《Research Policy》2014

Policy makers take initiatives to stimulate knowledge ecosystems in technology hotspots. It is implicitly assumed that these ecosystems will lead to value networks through which the participating companies can realize a competitive advantage. Value networks refer to business ecosystems where the value proposition is offered by a group of companies which are mutually complementary. The strategy literature suggests that business ecosystems lead to competitive advantages for each of the partners in the ecosystem. Based on a unique hand-collected database of 138 innovative start-ups in the region of Flanders, we analyze the knowledge and business ecosystem and the financial support network. We find that the knowledge ecosystem is well structured and concentrated around a number of central actors while the business ecosystem is almost non-existent at the local level. Further, we find that the financial support network is almost 100% publicly backed and fails to bridge the knowledge and business ecosystem. The implications for policy makers who tend to focus on the development of local ecosystems are discussed.  相似文献

相遇信息估算概率的机会网络路由协议     

龚丁海 《科技通报》2014,(11)

在分析现有机会网络转发策略的基础上,根据Prophet和Spray and wait协议的特点提出一种相遇信息估算转发概率的机会网络路由协议(BPAS),BPAS以节点相遇的频率、相遇的连通时长和断连时长作为参量引入转发概率的计算,消息转发给转发概率大的节点,使得消息朝更靠近目的节点方向发送。仿真结果表明,BPAS协议与Epidemic协议、Prophet协议和Spray and wait协议相比,能获得更高的消息交付率和更低的通信开销,消息总转发次数更少。实验证明BPAS协议能适应于节点密度较大的机会网络环境。  相似文献

高洪波  廖明潮 《科技通报》2014,(9)

如何能够更好的提高节点定位一直都是WSN研究的重点,本文在DV-HOP定位算法的基础上,从误差精度,锚节点稳定度和反向学习选择-最小二乘估计来对节点定位的3个方面进行改进。首先在定位误差精度中引入混沌优化算法,其次在锚节点处理中引入稳定度概念,最后在未知节点定位中引入反向学习和最小二乘估计。改进后的算法在通信半径和拓扑结构两个方面进行了仿真实验,实验表明,本文算法能够有效的减少计算带来的定位误差,提高定位精度。  相似文献
