摘要：Determining whether investments in information technology (IT) have an impact on firm performance has been and continues to be a major problem for information systems researchers and practitioners. Financial theory suggests that managers should make investment decisions that maximize the value of the firm. Using event-study methodology, we provide empirical evidence on the effect of announcements of IT investments on the market value of the firm for a sample of 97 IT investments from the finan...

摘要：Information technology is slowly becoming a part of educational classrooms and corporate training facilities. The current study examines the use and outcomes of computer-based instructional technology in the context of graduate business education. Case study data is gathered to explore how computer technology is used in the university classroom, and how computer-based teaching methods differ from traditional teaching methods in terms of class interaction and in-class learning. The study found ...

摘要：The value of mathematical modeling and analysis in the decision support context is well recognized. However, the complex and evolutionary nature of the modeling process has limited its widespread use. In this paper, we describe our work on knowledge-based tools which support the formulation and revision of mathematical programming models. In contrast to previous work on this topic, we base our work on an indepth empirical investigation of experienced modelers and present three results: (a) a m...

摘要：A major tenet in organizational behavior literature is that feedback improves performance. If feedback is thought to improve performance, then individuals should actively seek feedback in their work. Yet, surprisingly, individuals seldom seek feedback perhaps because of face-loss costs of obtaining feedback face-to-face. Furthermore, in cases where the giver is perceived to be in a bad mood, individuals may be even more reluctant to seek feedback if they believe seeking feedback risks the give...

摘要：One fundamental requirement in the expected utility model is that the preferences of rational persons should be independent of problem description. Yet an extensive body of research in descriptive decision theory indicates precisely the opposite: when the same problem is cast in two different but normatively equivalent frames, people tend to change their preferences in a systematic and predictable way. In particular, alternative frames of the same decision-tree are likely to invoke different s...

摘要：Seventeen major types of information systems are identified and defined by vectors of their attributes and functions. These systems are then classified by numerical methods. The quantitative analysis is interpreted in terms of the development history of information system types. Two major findings are that the numerical classification autonomously follows the chronological appearance of system types and that, along the time line, systems have followed two major paths of development; these have...

摘要：A large number of studies have been conducted during the last decade and a half attempting to identify those factors that contribute to information systems success. However, the dependent variable in these studies I/S success has been an elusive one to define. Different researchers have addressed different aspects of success, making comparisons difficult and the prospect of building a cumulative tradition for I/S research similarly elusive. To organize this diverse research, as well as to pres...

摘要：This paper reports on an effort to integrate symbolic and mathematical models to tailor the output of a mathematical model to the particular domain of a decision maker. AESOP combines the Black-Scholes model of stock options pricing with an expert system; the integrated model is designed for use by an options specialist on the American Stock Exchange. The specialist makes a number of adjustments to the output of the mathematical model; the purpose of the symbolic model is to make as many of th...

摘要：After-hours telecommuting (AHT) is a work arrangement where job -relevant work is done at home on a computer outside of regular office hours. This study examined how after-hours telecom muting affects an individual's ability to balance work and family demands (measured as role overload, spillover of interference from work to family and spillover of interference from family to work). It also examined the impact of gender and maternal career employment on these relationships. The analysis showed...
