社交网的远程学习应用研究

随着计算机互联网技术飞速发展,基于互联网技术的远程学习形式层出不穷,探索提高远程学习质量的适宜远程学习的技术手段方兴未艾。通过对国内外有关远程学习理论及技术的阐述及相关调研、对社交网相关技术和应用进行分析,构建了基于SNS技术的远程学习新形式。借助SNS技术提高学习的兴趣,进而改善远程教育的交互,还可应用于日校的辅助教学、培训等领域。     

中国商贸物流企业海外物流节点选择策略研究

基于国家节点的拓扑结构和经济属性,构建"一带一路"沿线国家的拓扑重要性与经济重要性评价指标体系,运用熵权-TOPSIS法对国家节点的重要性进行综合评估。研究表明:俄罗斯、印度、马来西亚、新加坡、阿联酋等国的拓扑重要性与经济重要性排名均靠前,地理位置与战略地位十分重要,投资与建设环境稳定,是我国商贸物流企业"走出去"优先选择的投资建设重点;哈萨克斯坦、蒙古、塞尔维亚、老挝等国,拓扑重要性排名靠后,其物流市场和基础设施建设空间很大,是潜在的投资建设区域;伊拉克、阿富汗、巴勒斯坦等国拓扑重要性与经济重要性排名均靠后,地缘政治复杂,投资与营商环境不稳定,有着较高的投资建设风险。     

关于网络人际信任危机的探讨

近年来,网络科学技术的飞速发展,大大加强了人与人之间沟通与交流的同时,也带来了网络交往过程中的人际信任危机问题。人们对其＂信任＂之余,也逐渐产生了＂怀疑＂。由此,试分析网络人际信任危机产生的原因,并尝试提出相应的解决对策具有重要的现实意义。     

A social capital approach to improving public relations’ efficacy: Diagnosing internal constraints on external communication

This article extends Heath's (2006) concept of fully functioning society theory (FFS) and argues that public relations can be used as a force to enhance collective social capital in communities. To serve this purpose, however, the effectiveness of an organization to serve its external publics is often dependent on the status and relationships the public relations function has developed within the organization. This paper provides a network analysis of a government agency in Jordan that illustrates the relationship between internal organizational social capital and the potential problems for establishing external relationships with publics. Implications for public relations research methods and theory are also discussed.     

Power and the perception of social networks

Previous work has led to divergent conclusions about how power affects the accuracy of network perceptions in groups and organizations. This paper develops and tests an argument linking higher power to less accurate network perception. Results from the first experiment showed that, relative to participants primed with high power, those primed with low power had more accurate perceptions of who was tied to whom in novel networks. The second experiment demonstrated that such differences in perceptual accuracy do not emerge for non-social relations.     

我国视频网站发展态势与前瞻

网络视频在我国经历了七年多的竞合发展。与国外的差异化发展模式不同,我国的视频网站呈现内容多样、各有侧重的特点。目前视频网站既有"旧病"又有"近忧",用户粘性不强成为其面临的核心问题。未来视频网站发展应在内容和技术两个层面着力。在内容层面,应建立内容生态圈,发展网络院线;在技术层面,应实现情境化播放,利用好大数据挖掘技术。     

网络媒体时代思想教育的价值生成与实现

以互联网为代表的信息网络技术日益普及,使高校思想政治教育进入网络这个符合时代主题的新的教育领域中。网络媒体时代的思想教育价值生成的关键所在,就是网络媒体时代的思想教育实践活动。思想教育价值生成、展开、确立的过程,是整合、统领、引导社会思潮的历时性过程。     

Risk management and managerial efficiency in Chinese banks: A network DEA framework

Risk management in Chinese banks has traditionally been the Cinderella of its internal functions. Political stricture and developmental imperative have often overridden standard practice of risk management resulting in large non-performing loan (NPL) ratios. The training and practice of risk managers remain second class compared with foreign banks operating in China. This paper surveys Chinese bank risk managers and constructs metrics of risk management practice and risk management organisation. The metrics are used as intermediate inputs in a Network DEA framework to produce a measure of income efficiency. A statistical test is carried out to assess the importance of the risk metrics in evaluating bank income efficiency.     

Hierarchical production planning for multi-product lines in the beverage industry¶

Multi-commodity production and distribution scheduling is one of the most complex and crucial problems facing many manufacturing companies. For a major European manufacturer specialising in bottling juices and drinks, we have designed and developed a hierarchical decomposition approach to the solution of the multi-commodity production planning problem. In this paper we focus our attention on the coarsest decomposition level, called multi-commodity aggregate production planning (MCAP). It concerns the choice of the best feasible production plan for a set of products (commodities) over an extended time horizon so as to meet forecast aggregate demands throughout the horizon. At this level, the problem constraints include hard constraints (such as production lines having a maximum capacity and products having short life-times), and soft constraints (budgetary concerns.) The objective is to determine the production plan that covers each period's demands as best as possible, while minimizing all relevant costs. Our method for solving MCAP produces optimal plans in negligible times in commodity PC workstations.
