信息网络化对高校科研管理的影响及对策

信息网络化对高校科研管理工作带来了机遇和挑战。传统条件下科研管理存在诸多弊端 ,如科技计划管理的各个阶段已越来越不适应信息时代的发展 ,推广手段落后、信息渠道不畅造成高校科技成果转化率低 ,难以形成产业化 ,科研管理存在较大的随意性等。信息网络化对科技计划管理、科技成果转化、科研管理的规范化建设等均有极大的促进作用。适应信息网络化的要求 ,必须转变思想观念 ,尽快实现校园科研管理的网络化 ,高校科研管理人员信息能力的培养和科研管理的规范化建设     

网络化与校园管理

计算机网络技术的发展 ,使人类全面进入网络化时代 ,作为社会重要组成部分的校园 ,在管理理念、管理方式、运营模式、组织结构、校园秩序、服务质量、人员素质等方面都将发生重大的改变。校园的管理真正实现了现代化。     

基于最大熵谱估计的机载雷达杂波抑制技术

在讨论机载雷达地面杂波的基础上，利用最大熵估计法对机载雷达杂波进行抑制，并引入了ｃｈｏｌｃｓｋｙ分解快速算法求解最大熵谱的ＡＲ模型参数。计算机模拟表明，基于最大熵谱估计的机载雷达杂波抑制技术有很高的谱分辨率，不仅能跟踪主杂波的频率位置而且能跟踪其谱宽度，因而具有较为满意的杂波对消化与改善因子。     

二元序列优化的二种快速算法

基于二相编码雷达对大压缩比信号的要求,提出了一种比直接算法平均提高效率0.5P(P 为序列长度)的快速数字优化方法。作为这种快速算法的实际应用,还对 P=255的二相编码脉冲压缩信号进行了优化。     

降低线性调频脉冲压缩信号旁瓣的方法

讨论线性调频脉冲压缩信号距离旁瓣的抑制。研究如何降低小时带积线性调频信号距离旁瓣电平问题,针对该信号频谱矩形特性差,提出了采用频谱修正方法来提高脉冲压缩信号的主副比。该方法具有全数字式处理特点,适宜使用IMS A100器件实现脉冲压缩处理。计算机模拟结果表明,无论是小时带积还是大时带积的线性调频信号,经谱修正后,脉冲压缩信号的主副比均舍得到提高。     

加强大学生媒介素养教育的基本逻辑与现实路径

网络化已成为大学生的一种生存方式,但网络媒介的双重属性决定了它对社会生活的负面效应不可避免,引导大学生适应媒介化社会生活势在必行。新时期加强大学生媒介素养教育的逻辑起点在于：网络行为异化造成大学生社会角色迷失及其人格支离破碎;网络行为约束机制缺失冲击着大学生网络道德构建;网络媒介负外部性侵蚀着大学生身心健康。加强大学生媒介素养教育、构建立体化媒介素养教育模式,应着力于培育大学生的媒介伦理素养与主体意识,增强责任意识,理性使用网络媒介;大力强化教育管理者的网络媒介素养,提升实践育人能力,发挥协同效应;全力优化网络生态,降低网络环境对媒介素养教育的影响的风险。     

Hybrid social and news media protest events: from #MarchinMarch to #BusttheBudget in Australia

Public protest events are now both social media and news media events. They are deeply entangled, with news media actors – such as journalists or news organisations – directly participating in the protest by tweeting about the event using the protest hashtag; and social media actors sharing news items published online by professional news agencies. Protesters have always deployed tactics to engage the media and use news media agencies’ resources to amplify their reach, with the dual aim of mobilising new supporters and adding their voice to public, mediatised debate. When protest moves between a physical space and a virtual space, the interactions between protesters and media stop being asynchronous or post hoc and turn instantaneous. In this new media-protest ecosystem, traditional media are still relevant sources of information and legitimacy, yet this dynamic is increasingly underpinned by a hybrid interdependency between traditional news and social media sources. In this paper we focus on an anti-austerity government movement that arose in Australia in early 2014 and was mobilised as a series of social media driven, connective action protest events. We show that there is a complex symbiotic interdependency between the movement and the traditional media for recognition and amplification of initial protest events, but that over time as media interest wanes, the movements’ network becomes disconnected and momentum is lost. This suggests that the active role traditional media play in protest events is being underestimated in the current research agenda on connective action.     

Leveraging the common and outsourcing the distinct: institutional difference and multinational company identity in emerging economies

ABSTRACT

This paper explores the challenges of outsidership faced by multinational companies (MNCs) accessing emerging economies. The paper departs from popular conceptualisations of culture drawing instead on social identity theory as part of an institutions-based view, to explain how employing a singularities approach can allow the identification of commonalities of Indianness and Australianness that can be leveraged to ameliorate negative socially embedded business norms that pose a challenge to MNC success in emerging economies. This study shows that despite recognised formal (regulatory) and informal (cultural) differences, managers of Australian MNCs operating in India were able to innovatively identify and exploit cultural commonalties/singularities to ease cultural adjustment and mitigate intergroup conflict, allowing them to achieve an innovative institutional fit. The paper discusses how, using this approach, sole-venture MNCs can access many of the benefits provided by collaborative entry modes while preserving MNC identity. We further propose that the singularities approach can provide a valuable starting point to develop culturally appropriate competence training initiatives.     

网络社会问题与控制

网络社会问题是当今社会日益严重的全球性问题.网络社会问题的类型有:网络犯罪和网络黑客、网络色情、信息化污染、网络沉溺、信息垄断与两极分化等等.网络社会问题具有以下特征:全球性、高技术性、主观认定上的文化差异性、后果控制的艰难性.根据这些特征,网络社会问题的控制要诉诸技术、法律、道德和人文观念的力量.
