Cookie炙烤隐私权

信息技术的进步为隐私权的保护提出了许多前所未有的问题,我们需要在技术进步与个人信息和隐私权保护之间寻找一个边界或平衡点几乎所有的网站设计者在进行网站设计时都使用了Cookie,因为他们都想给浏览网站的用户提供一个更友好的、人文化的浏览环境,同时也能更加准确地收集访问者的信息。Cookie虽然被广泛地应用并能做到一些使用其它技术不可能实现的功能,但也存在一些不够完美的方面,收集用户个人信息甚至可能侵犯公民隐私权这点便使Cookie备受诟病。我们需要在技术进步与个人信息、隐私权保护之间,寻找一个边界或平衡点。

Competing technologies and industry evolution: The benefits of making mistakes in the flat panel display industry

This article investigates the post‐entry implications of pre‐entry technological choices made during the uncertain period before a dominant design. Building on work on technological dynamics and organizational inertia, I argue that too early commitments to the winning technology may impede the ability to bring the best product to market, but delaying investment too long limits the ability to accumulate useful knowledge. Using data from the evolution of the flat panel display industry from 1965 to 2005, the study shows empirical support for the two theoretical mechanisms and offers the surprising result that firms starting in the losing technology before switching outperform other firms in terms of product value. Switching, while difficult behaviorally in recovering from failure, both delays difficult‐to‐reverse technological commitments and develops market knowledge.

On the development and application of a self–organizing feature map–based patent map

Recently, the range of R&D management has expanded to include management of technological assets such as technology information, product/process data, and patents. Among others, patent map (PM) has been paid increasing attention by both practitioners and researchers alike in R&D management. However, the limitation of conventional PM has been recognized, as the size of patent database becomes voluminous and the relationship among attributes becomes complex. Thus, more sophisticated data–mining tools are required to make full use of potential information from patent databases. In this paper, we propose an exploratory process of developing a self–organizing feature map (SOFM)–based PM that visualizes the complex relationship among patents and the dynamic pattern of technological advancement. The utility of SOFM, vis–à–vis other tools, is highlighted as the size and complexity of the database increase since it can reduce the amount of data by clustering and visualize the reduced data onto a lower–dimensional display simultaneously. Specifically, three types of PM, technology vacuum map, claim point map, technology portfolio map, are suggested. The proposed maps may be used in monitoring technological change, developing new products, and managing intellectual property.     

Freedom to surf: the positive effects of workplace Internet leisure browsing

It is commonly believed that for workers to browse the Internet for personal reasons during work hours is non‐productive. Contesting this belief, this study documents positive effects of workplace Internet leisure browsing (WILB) on employee productivity. It is argued that WILB is an unobtrusive interruption which enables restoration of mental capacity and fosters feelings of autonomy.     

Unveiling the successful process of technological transition: a case study of Matsushita Electric

Technological transition requires serious management decisions because it essentially means withdrawing from an existing technology, in which the company has been successful, and shifting management resources to a new technology with a high degree of uncertainty. We will analyze in detail an example of a successful transition to a new technology and draw key factors for success. The subject of our analysis is the transition made by Matsushita Electric Group (MEG), a large corporate group representative of Japanese companies, at the time of its commercialization of plasma display panel (PDP) TVs. During commercialization process, Matsushita made a successful transition from accumulated direct current‐plasma display panel (DC PDP) to alternating current‐plasma display panel (AC PDP) through incorporating AC PDP technology from Plasmaco, Venture Company established in 1987. Key conceptual contributions are as follows. Old and new technology can differ in their knowledge base. According to existing literature, when the knowledge base is radically different, incumbent firms have a difficulty adapting to the technological change. On the other hand, when the knowledge base is very similar, incumbent firms have no trouble adapting to the change. Beyond these established existing understandings, this paper argues that when the knowledge base is moderately different, managers can increase the likelihood of successful transition by implementing a set of organizational strategies. Among these strategies, a particularly insightful one is that through the parallel development process of both existing and new technologies, managers can eventually integrate the advantages of both technologies by implementing a flexible resource allocation mechanism to overcome the dichotomy between old and new through creation of a ‘Ba’, Japanese concept offering shared context for knowledge creation.     

基于科技资源配置效率视角对北京高新技术产品国际竞争力的实证分析

本文从显示性指标和分析性指标两个方面来评价高新技术产品国际竞争力。第一步利用显示性指标对北京高新技术产品国际竞争力的现状及发展潜力进行剖析;第二步利用分析性指标来深入挖掘影响北京高新技术产品国竞争力提升的重要因素。即利用贸易竞争指数和MI指数分别测算高新技术产品国际竞争实力和国际竞争潜力;利用因子分析的方法计算出各省市区的科技资源的配置效率。研究结果表明:北京高新技术产品国际竞争实力较弱,但发展趋势呈上升态势;北京的科技资源配置效率低是影响高新技术产品国际竞争力较弱的重要因素。     

Commercial software,adware, and consumer privacy

I study the choice between selling new software commercially and bundling it with ads and distributing it for free as adware. Adware allows advertisers to send targeted information to consumers which improves their purchasing decisions, but also entails a loss of privacy. I show that adware is more profitable when the perceived quality of the software is relatively low, when tracking technology improves, when consumers benefit more from information on consumer products and are less likely to receive it from external sources. I also show that improvements in the technology of display ads will lead to less violation of privacy and will benefit consumers, that depending on the software's quality, there are either too many or too few display ads in equilibrium, and that from a social perspective, adware dominates commercial software.     

中小型制造企业创新特征分析:基于德阳企业调查数据

本文利用2009年四川德阳地区地震灾后中小型企业调查数据,从产业、所有制及企业规模等角度系统地考察了当地中小型企业的创新特征,并分析了其中存在的主要问题。我们发现,企业的平均专利数量及专利结构具有明显的产业异质性,在考虑专利申请的集中度后,产业的专利密度与研发密度呈现负相关性;各种不同所有制企业在创新动力、创新类型与创新的信息来源方面存在显著差异;发明专利密度与企业规模呈倒U形关系,而实用新型及外观设计专利密度随企业规模的增大而减小;政府研发资助存在选择效应,规模较大的企业更有可能获得政府的创新扶持。本文突破既有研究的数据限制,为我国中小型企业在创新模式转变中的差异性提供了证据,并为政府相应的创新扶持政策提供了借鉴。

Net neutrality and innovation at the core and at the edge

How would abandoning Internet net neutrality affect content providers that have different sizes? We model an Internet broadband provider that can offer a different quality of service (priority) to heterogeneous content providers. Internet users can potentially access all content, although they browse and click ads with different probabilities. Net neutrality regulation effectively protects innovation done at the edge by small content providers. Prioritization, instead, increases both infrastructure core investment and welfare only if it sufficiently stimulates innovation from the large content provider.
