摘要：Information technology (IT) services providers are exposed to exogenous risks faced by the industry as a whole, and endogenous risks from their Current portfolio of IT contracts. This exposure may lead to cost overruns or legal responsibility for service-level breeches. Providers can leverage information about their risk positions implied by their IT services contract portfolios to gain strategic advantage over their competitors. We build theory in support of a new construct, profit-at-risk, f...

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 topic of trust in information technology (IT) artifacts has piqued interest among researchers, but studies of this form of trust are not definitive regarding which factors contribute to it the most. Our study empirically tests a model of trust in IT artifacts that increases our understanding in two ways. First, it sets forth two previously unexamined system quality constructs-navigational structure and visual appeal. We found that both of these system quality constructs significantly predi...

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：Organizations are faced with a variety of information security threats and implement several information system security countermeasures (ISSCs) to mitigate possible damage due to security attacks. These security countermeasures vary in their ability to deal with different types of security attacks and, hence, are implemented as a portfolio of ISSCs. A key challenge for organizations is to understand the economic consequences of security attacks relative to the ISSC portfolio implemented. This...

摘要：Online reputation systems are intended to facilitate the propagation of word of mouth as a credibility scoring mechanism for improved trust in electronic marketplaces. However, they experience two problems attributable to anonymity abuse-easy identity changes and reputation manipulation. In this study, we propose the use of stylometric analysis to help identify online traders based on the writing style traces inherentin their posted feedback comments. We incorporated a rich stylistic feature s...

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...
