Governing software: networks,databases and algorithmic power in the digital governance of public education     

Ben Williamson 《Learning, Media and Technology》2015,40(1):83-105

This article examines the emergence of ‘digital governance’ in public education in England. Drawing on and combining concepts from software studies, policy and political studies, it identifies some specific approaches to digital governance facilitated by network-based communications and database-driven information processing software that are being discursively promoted in education by cross-sectoral intermediary organizations. Such intermediaries, including National Endowment for Science, Technology and the Arts, Demos, the Innovation Unit, the Education Foundation and the Nominet Trust, are increasingly seeking to participate in new digitally mediated forms of educational governance. Through their promotion of network-based pedagogies and database-driven analytics software, these organizations are seeking to delegate educational decision-making to socio-algorithmic forms of power that have the capacity to predict, govern and activate learners' capacities and subjectivities.  相似文献

How can science connect with and contribute to conservation? Recommendations and reflections     

Agnes W. Brokerhof 《文物保护研究》2015,60(6):7-13

This paper reports the conclusions and recommendations of the working group that synthesized the discussions on ‘How can science connect with and be of greater benefit to conservation practice?’ during the ICCROM Forum on Conservation Science. The author reflects on these findings from her own perspective and experiences, and places them in the context of two major shifts in heritage research: the first, a shift in focus from conserving materials to managing meaning. The second, a shift in organizational structures from single, centrally funded heritage institutions towards diffuse networks which include new players who have no direct responsibility towards heritage. Both shifts are taking place in an environment of decreased funding and increased accountability to society. Science and conservation connect and contribute to each other most effectively if they together contribute to the societal benefits of heritage. In this regard, heritage science strategies can stimulate collaboration, and direct science and conservation towards innovative, applicable outcomes. Moreover, they can promote a transdisciplinary approach which connects social, economic and business sciences and stakeholders. They should also ensure the creation of sustainable nodes for consolidating knowledge within these dynamic networks.  相似文献   

机会网络中节点协作的Epidemic路由算法     

龚丁海  覃少华  彭建盛 《河池学院学报》2015,(2):84-88

Epidemic路由算法是一种多副本路由算法,在资源受限的情况下,会由于无限制的洪泛使得网络中存有大量的消息副本,消耗大量网络资源,导致网络性能下降。针对Epidemic路由算法中存在的问题,提出一种基于节点协作的Epidemic路由算法,该算法通过节点间相互的协作和一定策略抑制网络中副本数多的消息的转发机会,提高副本数少的消息的转发机会,进而控制网络中总的消息副本的增长,以此保证消息转发公平性和较好的网络性能。仿真结果表明,与传统的Epidemic路由算法和Prophet路由算法相比,该路由算法能显著提高消息的交付率,减少消息传输延迟和路由开销,有效提高了网络总体性能。  相似文献   

论简·爱的自卑与柔弱     

张伟华 《安阳工学院学报》2011,10(5):83-85

尽管简·爱总是被看作一个经典的自信坚强的形象,她毕竟是一个普普通通的女孩,她的思想和情感复杂而又时时发生变化。本文旨在通过分析简·爱得知罗切斯特夫人尚在人世之后的想法和行为,来得出结论:简·爱在自信和坚强的同时也充满了自卑和柔弱。然而,正是有了这一份自卑和柔弱,简·爱的形象更为丰满,她对平等和真爱的追求也更加彰显了其超越时代超越性别的非凡意义。  相似文献   

复辞辞格形成的多样性     

马晓红 《毕节学院学报》2011,29(11):7-12

与其他辞格相比,复辞未得到应有的重视,但是自先秦开始到现在,这种辞格的应用一直非常广泛。多种修辞格如转类、拈连、对偶、同异、排比、双关、顶针、回文等均可以形成复辞,显示了复辞形成的独特性。  相似文献   

“We bleed for female empowerment”: mediated ethics,commodity feminism,and the contradictions of feminist politics     

Lisa A. Daily 《传播与批判/文化研究》2019,16(2):140-158

Discourses of female empowerment are increasingly prominent within ethical capitalism, which seeks to remedy global crises with private-sector solutions and their commodities. This article examines the intersecting manifestations of female empowerment, commodity activism, and ethical capitalism with case studies on Born Free Africa, a fashion collection combatting mother-to-child HIV transmission, and THINX, which sells “period-proof” panties. Each company articulates empowerment through a binary between the Western feminist savior and “in-need” woman of the global south. This article argues that this iteration of empowerment not only reinforces logics of neo-colonial capitalism, but also masks disciplinary regimes for individual feminine subjects.  相似文献

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
