模块化生产网络的治理:一个分析框架

在全球化生产背景下,模块化生产网络面临复杂的环境,从而带来一系列的风险.文章针对模块化生产网络中的关系风险、绩效风险和嵌入性风险,提出了一条网络治理的分析路径.它主要包括治理环境、治理模式、治理机制和治理目标,其中治理模式有紧密型治理和松散型治理,治理机制包括合同治理和关系治理,治理目标主要是防止机会主义,提高运作绩效和消除锁定效应.沿着这线索,文章构建了一个模块化生产网络治理的系统分析框架.     

Social media? Get serious! Understanding the functional building blocks of social media

Traditionally, consumers used the Internet to simply expend content: they read it, they watched it, and they used it to buy products and services. Increasingly, however, consumers are utilizing platforms—such as content sharing sites, blogs, social networking, and wikis—to create, modify, share, and discuss Internet content. This represents the social media phenomenon, which can now significantly impact a firm's reputation, sales, and even survival. Yet, many executives eschew or ignore this form of media because they don’t understand what it is, the various forms it can take, and how to engage with it and learn. In response, we present a framework that defines social media by using seven functional building blocks: identity, conversations, sharing, presence, relationships, reputation, and groups. As different social media activities are defined by the extent to which they focus on some or all of these blocks, we explain the implications that each block can have for how firms should engage with social media. To conclude, we present a number of recommendations regarding how firms should develop strategies for monitoring, understanding, and responding to different social media activities.

战术Ad Hoc网络中的QoS路由协议设计与仿真

基于TDMA的战术Ad Hoc网络,提出一种分布式的资源预约机制,其中收/发节点采 用协商的方式预约时隙,邻居节点通过侦听方式获得时隙被预约的信息,然后依托该机制提 出一种QoS路由协议,该协议能够在网络节点之间选择一条满足QoS要求且相对短的路径进行 预约时隙,同时对于网络拓扑变化引起的链路故障也能局部修复。仿真表明该协议具有开销 小和可靠性高等特点,能够提高战术Ad Hoc网络的QoS保障能力。

基于“北斗一代”的Zigbee无线网关设计

为了解决野外多点数据采集无供电、布线复杂和通信困难的问题,提出了一种基于“北 斗一代”的Zigbee无线网关设计方案。采用MSP430F6438、CC2341微处理器和一体化的RDSS “北斗”射频芯片完成低功耗、小成本的硬件设计。通过增加SIM卡的数量,将网关转发“ 北斗”数据的频率降至最低的5 s,提高了网关的通信速率。通过软件设计实现了Zigbee无 线传感网络和“北斗一代”系统之间数据的透明交换。该方法已成功应用于野外油气井远程 监控系统中。     

产业集群的自我否定与跨网络学习——以浙江温州低压电器产业集群为例

我国本土产业集群在经过一段时间的高速发展后,围绕＂锁定＂存在的诸多矛盾和潜在风险等问题都逐渐暴露出来,而产业集群升级始终不能很好解决,并成为困扰我国实践和理论的一个棘手问题;文章在辨析产业集群内外双重锁定的基础上,指出升级仅适合集群发展初级阶段时的内部＂锁定＂,而集群发展到高级阶段并面临外部＂锁定＂时,往往不能突破而陷入＂升级悖论＂;基于跨网络学习的视角,本文认为集群只有彻底自我否定,并融入跨国企业网络,才能突破来自内外的双重锁定,获得学习和知识溢出的机会;最后,结合我国浙江温州低压电器产业集群案例,分析在面临跨国公司竞争压力下,本土产业集群如何融入跨国企业网络,并寻求新的发展机会的学习路径。     

The life cycle of a metropolitan business network: Liverpool 1750–1810

Recently historians have complicated their understanding of networks. In particular, they have started to assess the role of networks in civic and formal arenas. This paper posits a quantitative methodology for a more nuanced and sophisticated analysis of mercantile networks within this environment. It uses visual analytics of Liverpool's business networks comprising political, trade, social and cultural institutions to assess their role in the changing social and economic climate during the period 1750–1810. This paper demonstrates the dynamic role of networks in the shaping of a metropolitan economy and the interplay between the two. In addition, it posits that, as is the case for regional clusters, there is a life cycle of networks. In this way, we are able to see how the networks sustained, nurtured and transformed social and economic activity during this period.     

The power of market mood — Evidence from an emerging market

This article focuses on investor behavior and, consequently, the mood in the market. By using a self-organizing network we develop a model which tries to capture the market mood and serves as an indicator of the reasonableness of selling or purchasing securities. In this sense, the final result of this model is the same as in the model-type prediction of future stock prices, with the only exception being that one is not required to know the concrete future values of the selected security. This will indirectly support the hypothesis that psychological factors are an important (if not key) market driving force.     

Towards an understanding of social networks among organizational self-initiated expatriates: a qualitative case study of a professional services firm

Drawing on a qualitative case study of 51 organizational self-initiated expatriates (OSIEs) in a professional services firm, this article investigates the role of networks during expatriation and, specifically, in the development of learning that is beneficial to both the individual expatriate and the global operations of the firm. First, we investigate the extent to which individual motivations to engage in OSIE impact on the development of networks. Second, we investigate individual's experiences of network development. Third, we investigate individual perceptions of the benefits of networks for both organizations and individual actors. The paper will report that professionals initiating their own expatriation develop continually expanding and composite networks such that mobility and networks evolve in a seemingly symbiotic relationship. In doing so, it contributes to our understanding of the role of agency in network development and extends our understanding of organizational self-initiated expatriation as a relatively under-researched phenomenon.
