Does IO Economics Really Make the Case for Investments in IT: A Rejoinder

The preceding critique [1] of the paper “The Information Problems in Organizations: A Research Model for the Value of Information and Information Systems” [3], reaches general conclusions with respect to the original paper and the applicability of economics to MIS research. These conclusions are based on arguments developed at a different level of analysis than that used in the original paper, and without considering the goals and intent of the original paper. The differences between the critique and the original paper are highlighted.     

In-house capability and supply chain decisions

This study considers an internal production option for a contractor and analyzes its effect on the supply chain decisions when the contractor has innovated and the subcontractor has an incentive for opportunistic behavior. In contrast to the single disclosure threshold in the benchmark scenario where the contractor lacks in-house capability, we find two thresholds in the referred scenario. When information misappropriation is possible and the contractor has in-house capability, the contractor will organize a coordinated supply chain only when innovations fall between the two thresholds. Compared to the benchmark scenario, in-house capability has a positive effect on the contractor's incentive to innovate and an ambiguous effect on the subcontractor's incentive to invest in the production process. When the contractor needs to incur an extra cost to build in-house capability, the contractor keeps the same levels of investment compared to the case of no additional in-house capability cost, whereas the subcontractor increases the levels of investment. Furthermore, we find that in the presence of potential misappropriation on the part of the subcontractor, the higher the level of in-house capability, the less likely the contractor will be to outsource innovative products that generate higher profitability. This study can explain why firms strategically outsource low-end products and produce high-end products themselves. This study provides new results on the effects of in-house capability on the strategic interactions of parties in supply chains and, hence, on supply chain efficiency.     

村民是如何化解环境健康风险的?

污染—疾病科学关系不清及制度安排问题等因素致信息不全,加之村民相关科学知识的缺乏,是村民环境健康风险认知的根本性障碍,但村民并没有如简单预设的那样处于"束手待毙"的状态。在乡村社区,村民利用"熟人社会"的社会结构和文化机制把有限的信息无限利用,有效地应对了信息不全的困境。面对外源性污染,并且无法改变污染现状的格局下,村民根据生活经验和常识策略性地化解健康风险。村落社会中的亲缘、地缘关系结构以及精英—大众结构也影响了村民对环境健康风险的规避。村民化解环境健康风险虽然缺乏成熟的科学指导,却有其独特的实践逻辑。     

信息环境、年报披露时间选择与下年盈余管理

年报披露时间是否有助于投资者合理估计下年盈余管理程度,不同信息环境对这种估计又有什么影响?本文利用2004-2006年间的3451家公司样本对此进行了检验.结果表明:年报披露时间与下年盈余管理负相关,年报披露时间能向市场传递有效的未来信号;在标准审计意见和有较高质量经营现金流量支持的信息环境下,年报披露时间选择对下年盈余管理的信号作用更强.这些结论对理解公司年报披露时间安排有一定积极意义.     

The Role of Innovation Characteristics and Perceived Voluntariness in the Acceptance of Information Technologies

The often paradoxical relationship between investment in information technology and gains in productivity has recently been attributed to a lack of user acceptance of information technology innovations. Diverse streams of research have attempted to explain and predict user acceptance of new information technologies. A common theme underlying these various research streams is the inclusion of the perceived characteristics of an innovation as key independent variables. Furthermore, prior research has utilized different outcomes to represent user acceptance behavior. In this paper we focus on individual's perceptions about the characteristics of the target technology as explanatory and predictive variables for acceptance behavior, and present an empirical study examining the effects of these perceptions on two frequently used outcomes in the context of the innovation represented by the World Wide Web. The two outcomes examined are initial use of an innovation and intentions to continue such use in the future, that is, to routinize technology use. Two research questions motivated and guided the study. First, are the perceptions that predict initial use the same as those that predict future use intentions? Our results confirm, as hypothesized by prior research, that innovation characteristics do explain acceptance behavior. The results further reveal that the specific characteristics that are relevant for each acceptance outcome are different. The second research question asks if perceived voluntariness plays a role in technology acceptance. Results show that external pressure has an impact on adopters' acceptance behavior. Theoretical and practical implications that follow are presented.

阿拉伯国家现代信息技术的发展与挑战

以计算机、互联网和卫星通讯为代表的现代信息技术自20世纪七十年代开始在全球飞速发展。信息全球化正改变着人们以往的生产和生活方式，发达国家凭借信息技术优势优先享有信息全球化带来的诸多裨益，而处于先天弱势的发展中国家如何面对信息不对称竞争已成为所在国文化安全战略的重要考量。同样，阿拉伯国家虽然与发达国家在该领域存在差距，但为了建立符合本国利益的信息化社会，这些国家正加大对信息技术的投入，一些依托自身优势条件发展信息产业的阿拉伯国家已崭露头角。     

试析狭义批判性思维

狭义批判性思维是对信息试图否定的思维方法,其逻辑机制包括否定、否定的否定、否定与肯定的辨证统一三种情况。批判性思维独具特征,在有效甄别信息、变革思维方式、推动学术创新、塑造创新型人才等方面有着重要的现实意义。     

Information subsidies and agenda-building during the Israel–Lebanon crisis

This study examined the impact of information subsidies on media coverage during a crisis. Using the July 2006 Israel–Lebanon conflict as a backdrop, this research reviewed access that U.S. military public affairs officers provided the media and analyzed subsequent coverage for the presence of the military's message. Coverage was more neutral to positive than negative. Items containing organizational messages were more positive; those quoting practitioner-facilitated sources introduced organizational messages into coverage and generated more positive coverage. Access to information subsidies had a positive impact on coverage and aided in the successful transfer of attribute salience from practitioners to the media.
