摘要：Electronic government is being increasingly recognized as a means for transforming public governance. Despite this increasing interest, information systems (IS) literature is mostly silent on what really contributes to the success of e-government Web sites. To fill this gap, this study examines the role of trust in e-government success using the updated Delone and McLean IS Success model as e theoretical framework. The model is tested via a survey of 214 Singapore e-government Web site users. ...

摘要：The use of a well-defined process is a widely recognized approach to increasing quality and productivity in software development. Building software processes from scratch each time is expensive and risky. Therefore, they are often created by tailoring existing processes and standards. Process tailoring is a knowledge-intensive activity. This research explores the link between knowledge support and software process tailoring performance under different levels of tailoring task complexity. It th...

摘要：In order to better understand the sociopsychological factors involved in employees' adaptation to new technology in organizations, we examine the role that two types of social networks-supportive and informational-play in individual adaptation to IT-induced change in a large financial company. Using survey data from 371 employees working in 133 different branches of the organization, we find that several aspects of the social networks relate to quality of employees' adaptation to the new techn...

摘要：Real-world predictive data mining (classification or regression) problems are often cost sensitive, meaning that different types of prediction errors are not equally costly. While cost-sensitive learning methods for classification problems have been extensively studied recently, cost-sensitive regression has not been adequately addressed in the data mining literature yet. In this paper, we first advocate the use of average misprediction cost as a measure for assessing the performance of a cost...

摘要：In this paper, we examine how the motivations and attitudes of open source software (OSS) developers affect their preference among the three common OSS license types-Strong-Copyleft, Weak-Copyleft,and Non-Copyleft. Despite the importance of the license type and developers to OSS projects, there is little understanding in open source literature of the license choice from a developer's perspective. The results from our empirical study of OSS developers reveal that the intrinsic motivation of cha...

摘要：It is recognized that change management is necessary for information technology implementation success. While there are a growing number of interorganizational systems (IOS) designed for the public, there is little study of and lack of clear guidelines on managing change related to their implementation. This research explores the phenomenon through the case study of a country-wide farecard system implemented in Singapore's public transportation system that involved several organizations and th...

摘要：Open source software (OSS) is now posing significant competition to proprietary or closed source software (CSS) in several software markets. In this paper, we characterize the response of a firm developing CSS (where the CSS is a revenue earner) to the presence of an OSS in its market. In particular, we look at the firm's choice of resource investments to improve quality and the firm's pricing decisions. We are primarily motivated by the following questions: Would a firm producing CSS produce ...

摘要：The application of real options techniques to information security is significantly different than in the case of general information technology investments due to characteristics unique to information security. Emerging research in the economics of information security has suggested real options analysis (ROA) as a potential technique for assessing the value of information security assets, but has focused primarily on the most effective level of investment and the configuration of intrusion p...
