当前广西网络社区发展状况及其建设探析

当前广西网络社区发展状况表现为：公共管理服务部门网站的社区,占据优势地位但数量偏少;民营网站的社区,成为竞争激烈的淘金新空间;综合性与行业性网站的社区各领风骚,但总体实力仍然不强;传统媒体网站的社区,有实力资源可转化利用,在适应今后＂三网融合＂需要上有待加强;基层网络社区,有所起步,前景广阔而尚匮乏。为推进广西网络社区...     

Cyberattack-resilient load forecasting with adaptive robust regression

Cyberattacks in power systems that alter the input data of a load forecasting model have serious, potentially devastating consequences. Existing cyberattack-resilient work focuses mainly on enhancing attack detection. Although some outliers can be easily identified, more carefully designed attacks can escape detection and impact load forecasting. Here, a cyberattack-resilient load forecasting approach based on an adaptive robust regression method is proposed, where the observations are trimmed based on their residuals and the proportion of the trim is adaptively determined by an estimation of the contaminated data proportion. An extensive comparison study shows that the proposed method outperforms the standard robust regression in various settings.

Internet Jurisdiction for E-commerce

Internet jurisdiction is an area of increasing concern to e-commerce because of the growth in cross-border e-tailing, both within the United States and globally. Therefore, the need for a global solution is also increasing. In response, this article first defines Internet jurisdiction, also known as cyber jurisdiction, and discusses the risks of Internet jurisdiction for retailers and consumers. Drawing from legal research, the authors examine the legal theories for jurisdiction and the application to e-commerce. Their focus is on United States law because both US and foreign businesses must understand US jurisdictional law due to increased globalization from expanding international trade and more frequent contact with US companies and markets brought about by the Internet. Since standards and case law are still developing worldwide, the authors conclude by providing managerial recommendations to reduce the uncertainty of jurisdiction, should legal action be initiated.     

Aux armes, citoyens: Cyber security and regulation in the United States

Government policy for cyber security in the United States relies on voluntary and cooperative action by the private sector and has, until now, explicitly rejected the use of mandate or regulation. This stands in contrast to other defense and homeland security issues, such as those involving border protection or transportation, where government intervention is the norm. The decision to rely on voluntary action for cyber security reflects influential trends in security policies, deregulation, and the government's relation to the Internet that continue to shape US policy even after the attacks of September 11. The result is an ineffectual policy that underestimates the role of government.     

网购供应链的低碳决策模型及其应用

文章基于定量研究和典型算例,针对网购供应链的低碳运作积极性不高的问题,对网购供应链的低碳决策问题进行了分析。通过考虑网购者的低碳意识对供应链需求函数进行了改进,在此基础上,根据网购供应链是否考虑碳信息发布成本,构建了两类决策模型,最后对模型及其应用进行了分析。文章研究得出以下结论：当网购供应链的初始低碳水平高于低碳标准时,网店及其供应商进行低碳运作的积极性就高;当网购供应链的初始低碳水平低于低碳标准时,考虑碳信息发布成本进行决策更有利于提高网购者的低碳意识,从而促进网购供应链进行低碳运作;同时,在网购者的低碳意识影响下,网购供应链是否进行碳信息发布,主要是与其的初始低碳水平有关。该结论为网购供应链进行低碳运营提供了决策依据。     

Development of virtual cyber‐tour in the virtual reality system

This study is to explain the importance and the necessity of virtual cyber‐tour in a virtual reality environment, and to present a way of its realization as a means to surmount the fundamental constraints in current tourism, arising mainly from the individual health, cost, leisure time, and the low perception on tourism culture. This virtual cyber‐tour using virtual reality technology will not only provide various indirect tour experiences to the existing tour resources, but also develop a new type of tour system, leading to new worlds which have not been accessible to the public because of various restrictions coming from the current technology, transportation means, and physical limits of human body. Thus, the cyber‐tour will be a new tour resource of totally different concept and also, its industrialization will result in the developments of new industries for virtual reality system, video production, and display media, creating lots of jobs and added value.     

Cybersecurity awareness and market valuations

This paper introduces a measure of firm-specific cybersecurity awareness that can be used in empirical research exploring cyber-related issues facing corporations. It extends and updates Gordon et al. (2010), who develop an indicator capturing the existence of disclosures related to “information security” and show a positive association between market valuation and their measure. Since publication of their paper, cyber-related events have become more frequent and salient, and disclosure of cybersecurity issues has become more extensive. Increased disclosure is largely due to a 2011 requirement by the Securities and Exchange Commission, which provides guidance for disclosure of cyber-related issues in 10-K filings. Based upon this post-guidance disclosure, we develop a new measure that captures the extent and relevance of cyber disclosures and show that the market positively values cybersecurity awareness. We also show that a more negative tone in cyber disclosures is associated with lower market values. Our results are robust to inclusion of measures of IT governance and controlling for the firm’s overall disclosure characteristics.
