Core and infrastructure business activities are vital to the organization, and are growing more and more dependent on information systems. Theory suggests that more core and infrastructure business activities would inspire more strategic information systems planning which in turn would result in greater planning effectiveness. One hundred thirty chief information officers in manufacturing companies completed a questionnaire about the extent that their organization performed core and infrastructure business activities, and carried out technical, personnel, and procedures planning. The findings showed that infrastructure activities lead to all three types of planning whereas core activities lead only to procedures planning. Moreover, they showed that technical planning leads to planning effectiveness whereas personnel and procedures planning do not. The findings suggest that future researchers might try to uncover the reasons that core activities do not lead to more information systems planning. For practitioners, the findings suggest that managers reconsider how their organizations respond to core and infrastructure needs, and whether they should adjust their information systems planning.  相似文献

Along with the diffusion of information and communication technologies (ICTs), work processes are becoming ever more knowledge intensive. In keeping with this trend, the number of informational (or knowledge) workers in Finland has more than tripled from 12% in 1988 to 39% in 2000. What makes the Finnish case unique and interesting is the exceptional speed with which the information sector of the economy has grown. A few years after facing the most severe economic recession in its history in the early 1990s, Finland is now considered to have an advanced information economy. However, our empirical analysis--based on survey data from 1988, 1994, and 2000--yields a somewhat more critical picture of the Finnish information society than what usually comes across in the mainstream media. The opportunities for social equality offered by the growth of informational work are far more limited than was the case with the transition from agricultural to industrial production.  相似文献

A considerable body of literature has demonstrated-- empirically as well as analytically--that information systems need to be situated to the local context of use. Yet for infrastructural information systems that span numerous contexts spread out globally, this is literally prohibitive. For these systems to work, it is necessary to strike a balance between sensitiveness to local contexts and a need to standardize across contexts. We analyze a key element in this, namely, spelling out the (largely invisible) "costs" that the different actors pay to achieve working solutions. Empirically, we draw from an ongoing case study. We analyze the attempts of a maritime classification company with 5500 employees located in 300 sites in 100 countries to develop an infrastructural information system to support the surveying of ships globally. We elaborate design implications and concepts relevant to developing information infrastructures that also apply to the context of developing countries.  相似文献

The process of information seeking involves a varied set of tasks and interactions. Exactly how the information seeker judges the relevance of what is retrieved has been a renewed area of interest in information retrieval studies. Various studies have identified facets or categories of relevance which go beyond simple topical relevance, and there has been some recent research on how these multi-dimensional concepts of relevance relate to the information seeking process. This study extends research on the relationship between multi-dimensional user relevance assignments and stage in the process of completing a task. Our results concur with and add detail to previous studies and suggest that users consistently identify relevance criteria beyond topical relevance. Our results also find a statistically significant relationship between the users’ stage in the search process and relevance categories chosen using the convenience sample chosen for this study.  相似文献

The ideologies of technological utopianism and national competitiveness are two common strands of twentieth century technology policy in developed nations. The former is the tendency to paint an unrealistic picture of schedule or benefits for a planned technological shift, while the latter is the use of a (real or imagined) advantage held by another nation as a justification for domestic policies. Both are techniques that can and have been used to sell technology policies to government, industry, and the public at large. This theoretical framework is used to analyze the emergence of the 'multimedia'/information infrastructure boomlet in Japan in the mid 1990s, and, in the context of the country's history and institutions, is used to explain the policy distortions that resulted.  相似文献

中国资源消耗与经济增长动态关系的检验与分析   总被引:1,自引:1,他引:1  
王亚菲 《资源科学》2011,33(1):25-30
随着人口继续保持增长、城市化进程进一步加快、经济结构进入快速转型期,各省经济要保持平稳较快的发展,必然会对自然资源产生更大的需求、对生态环境造成更大的压力。因此,对各地区经济系统的资源投入与消耗进行分析,对认清各省经济发展过程中的资源利用现状、调整可持续发展政策方向具有很强的现实意义。本文基于物质流核算框架下的物质投入核算方法,选取1990年-2008年数据,利用面板协整与误差修正模型对中国省级层面资源消耗与经济增长之间的动态关系进行了研究。研究结果表明:资源消耗与经济增长之间存在长期双向因果关系;化石能源消耗与人均GDP之间存在长期双向因果关系;矿物质消耗与人均GDP之间短期无因果关系;生物质消耗对人均GDP存在长期单向因果关系。并提出建议:短期内可采取控制矿物质消耗的政策;长期应采取化石能源的保护政策,大力开发生物质能源。  相似文献

While research underpinned by the resource-based view (RBV) appears to suggest that IT-enabled capabilities are positively linked to competitive advantage, such a link is often seen as a black box as the processes through which competitive advantage can be gained appears unclear. In particular, research appears to suggest that information processing capability is linked to decision-making effectiveness and competitive advantage; however, little research appears to examine the interrelationship among them. This study, drawing on the RBV, develops a mediation model to examine the link between competitive advantage and the key tenets of value, rarity, inimitability and non-substitutability of information processing capability in the context of business analytics; and whether this link is mediated through decision-making effectiveness. Based on data collected from 633 UK companies, this study shows that there is a positive link between the value, rarity and inimitability characteristics of information processing capability and competitive advantage, which is partially mediated by decision-making effectiveness. The findings contribute to the theoretical development of the RBV by developing a mediation model that looks inside the black box. They also contribute to managers’ knowledge and understanding of the mechanism through which the strategic value of information processing capability can be maximized.  相似文献

Domesticating Computers and the Internet   总被引:1,自引:0,他引:1  
The people who use computers and the ways they use them have changed substantially over the past 25 years. In the beginning highly educated people, mostly men, in technical professions used computers for work, but over time a much broader range of people are using computers for personal and domestic purposes. This trend is still continuing, and over a shorter time scale has been replicated with the use of the Internet. This paper uses data from four national surveys to document how personal computers and the Internet have become increasingly domesticated since 1995 and to explore the mechanisms for this shift. Now people log on more often from home than from places of employment and do so for pleasure and for personal purposes rather than for their jobs. Analyses comparing veteran Internet users to novices in 1998 and 2000 and analyses comparing the change in use within a single sample between 1995 and 1996 support two complementary explanations for how these technologies have become domesticated. Women, children, and less well-educated individuals are increasingly using computers and the Internet and have a more personal set of motives than well-educated men. In addition, the widespread diffusion of the PC and the Internet and the response of the computing industry to the diversity in consumers has led to a rich set of personal and domestic services.  相似文献

This article examines the key global, environmental and policy factors that act as determinants of e-commerce diffusion. It is based on systematic comparison of case studies from 10 countries--Brazil, China, Denmark, France, Germany, Mexico, Japan, Singapore, Taiwan, and the United States. It finds that B2B e-commerce seems to be driven by global forces, whereas B2C seems to be more of a local phenomenon. A preliminary explanation for this difference is that B2B is driven by global competition and MNCs that "push" e-commerce to their global suppliers, customers, and subsidiaries. This in turn creates pressures on local companies to adopt e-commerce to stay competitive. In contrast, B2C is "pulled" by consumer markets, which are mainly local and therefore divergent. While all consumers desire convenience and low prices, consumer preferences and values, national culture, and distribution systems differ markedly across countries and define differences in local consumer markets. These findings support the transformation perspective about globalization and its impacts. In terms of policy, the case studies suggest that enabling policies such as trade and telecommunications liberalization are likely to have the biggest impact on e-commerce, by making ICT and Internet access more affordable to firms and consumers, and increasing pressure on firms to adopt e-commerce to compete. Specific e-commerce legislation appears not to have as big an impact, although inadequate protection for both buyers and sellers in some countries suggests that mechanisms need to be developed to ensure greater confidence in doing business online.  相似文献
