Given the importance of IT investments in today’s organization, firms tend to spend increasing amounts of time and resources to better manage IT projects. However these projects continue to have high failure rates thus highlighting the need for improved risk management. A stream of IS research has focused on identifying several causes of managerial risks. The theory base that has been used in t...

Aside from cancer, stroke has long been the number one cause of death in Korea, followed by heart disease. Last year, our gov­ ernment reported that this order was reversed, due primarily to a decrease in stroke mortality (Figure 1). The change is strik­ ing; ten years ago (in 2002), stroke mortality was about two times higher than that of heart disease (77 per 100,000 vs. 36.9 per 100,000, res...

With the advent of social applications, the question arises of how organizations can utilize such technology for improving task performance. While social applications certainly bear the potential to trigger the development of radically new business models and business processes, we seek to study how the enrichment of IT-based routine work (simple tasks) by complementing social features (audienc...

ÿWe investigate how the superiority of the optimal subsidy or tariff in an international Cournot oligopoly depends on the production technology used in the industry, an interesting issue that has not been analyzed in the literature. We establish that the welfare superiority of the optimal subsidy or tariff depends on the relative steepness of the firms’ common marginal cost curve: when it is re...

36 instance of the satissability problem we associate a set of such matrices. The instance is called 1?semi?unitary if there is at least one 1?semi?unitary matrix in this set. Now 1 ? SEMI ? UNISAT is the satissability problem restricted to 1 ? semi ? unitary instances, KMb]. Given such parameters, 1 ? SEMI ? UNISAT can be solved in polynomial time. Problem 7.3 What is the complexity that we ca...

Source: Hacker, Eddy and Lewis (2002) A visual appreciation of Keane’s two-dimensional (m=2) bump function may be obtained from the graphical presentation (Fig.-1; Hacker et al., 2002). As the dimension (m) grows larger, the optimum value of the function becomes more and more difficult to obtain. Keane (1994) observed that for m=20 the value of min[f(x)] could be about -0.76 and for m=50 it cou...

Kobu, 2002). An enterprise can be then analyzed and integrated through its business processes. Thus, business process modeling (BPM) becomes a fundamental part of business process management, as it enables a common understanding and analysis of a company’s business processes. Particularly, BPM using computer-aided design tools and a standard visual form of notation to describe, validate, and si...

Recently, e-commerce becomes widespread; hence electronic department stores come into being. As a result, Chan and Chang proposed a scheme for digital gift certificates in 2002. Because it is hard to estimate the number of the clients of the electronic department stores, reducing the computation complexity of the electronic department stores becomes an important issue. Due to the need, we propo...
