Contributing knowledge to electronic knowledge repositories: an empirical investigation

Organizations are attempting to leverage their knowledge resources by employing knowledge management (KM) systems, a key form of which are electronic knowledge repositories (EKRs). A large number of KM initiatives fail due to the reluctance of employees to share knowledge through these systems. Motivated by such concerns, this study formulates and tests a theoretical model to explain EKR usage by knowledge contributors. The model employs social exchange theory to identify cost and benefit factors affecting EKR usage, and social capital theory to account for the moderating influence of contextual factors. The model is validated through a large-scale survey of public sector organizations. The results reveal that knowledge self-efficacy and enjoyment in helping others significantly impact EKR usage by knowledge contributors. Contextual factors (generalized trust, pro-sharing norms, and identification) moderate the impact of codification effort, reciprocity, and organizational reward on EKR usage, respectively. It can be seen that extrinsic benefits (reciprocity and organizational reward) impact EKR usage contingent on particular contextual factors whereas the effects of intrinsic benefits (knowledge self-efficacy and enjoyment in helping others) on EKR usage are not moderated by contextual factors. The loss of knowledge power and image do not appear to impact EKR usage by knowledge contributors. Besides contributing to theory building in KM, the results of this study inform KM practice.

An integrative study of information systems security effectiveness

As organizations become increasingly dependent on information systems (IS) for strategic advantage and operations, the issue of IS security also becomes increasingly important. In the interconnected electronic business environment of today, security concerns are paramount. Management must invest in IS security to prevent abuses that can lead to competitive disadvantage. Using the literature on security practices and organizational factors, this study develops an integrative model of IS security effectiveness and empirically tests the model. The data were collected through a survey of IS managers from various sectors of the economy. Small and medium-sized enterprises were found to engage in fewer deterrent efforts compared to larger organizations. Organizations with stronger top management support were found to engage in more preventive efforts than organizations with weaker support from higher management. Financial organizations were found to undertake more deterrent efforts and have stiffer deterrent severity than organizations in other sectors. Moreover, greater deterrent efforts and preventive measures were found to lead to enhanced IS security effectiveness. Implications of these findings for further research and practice are discussed.

Conflict and Performance in Global Virtual Teams

Increasing globalization and advances in communication technology have fuelled the emergence of global virtual teams (GVTs). There is much potential for conflict in GVTs as members work across cultural, geographical, and time boundaries. This study examines the antecedents of GVT conflict and the circumstances under which conflict affects team performance. An in-depth study of GVT conflict episodes was carried out using interviews, observations, communication logs, and documents. Based on findings from the teams under study interpreted in the light of prior literature, propositions are developed about the antecedents and effects of GVT conflict as stated. Within GVTs, cultural diversity is likely to contribute to both task and relationship conflict while functional diversity may result in task conflict. Large volumes of electronic communication and lack of immediacy of feedback in asynchronous media can contribute to task conflict. Moreover, the relationship between task conflict and team performance is likely to be contingent upon task complexity and conflict resolution approach. The influence of relationship conflict on performance may depend on task interdependence and conflict resolution approach. The conflict resolution approach may in turn be determined by the nature of conflict attribution. These propositions have been synthesized into a model to guide future empirical research and GVT practice.

Group Polarization and Computer-Mediated Communication: Effects of Communication Cues, Social Presence, and Anonymity

Group polarization is the tendency of people to become more extreme in their thinking following group discussion. It may be beneficial to some, but detrimental to other, organizational decisions. This study examines how computer-mediated communication (CMC) may be associated with group polarization. Two laboratory experiments were carried out. The first experiment, conducted in an identified setting, demonstrated that removal of verbal cues might not have reduced social presence sufficiently to impact group polarization, but removal of visual cues might have reduced social presence sufficiently to raise group polarization. Besides confirming the results of the first experiment, the second experiment showed that the provision of anonymity might also have reduced social presence sufficiently to raise group polarization. Analyses of process data from both experiments indicated that the reduction in social presence might have increased group polarization by causing people to generate more novel arguments and engage in more one-upmanship behavior. Collectively, process and outcome data from both experiments reveal how group polarization might be affected by level of social presence. Specifically, group discussion carried out in an unsupported setting or an identified face-to-face CMC setting tends to result in weaker group polarization. Conversely, group discussion conducted in an anonymous face-to-face CMC setting or a dispersed CMC setting (with or without anonymity) tends to lead to stronger group polarization. Implications of these results for further research and practice are provided.

Dimensions of national culture and corporate adoption of IT infrastructure

Corporate adoption of information technology (IT) infrastructure is a critical management issue that may be affected by national culture. Prior research has shown that dimensions of national culture affect development of national IT infrastructure as well as adoption and impact of IT applications. This study explores the impact of two dimensions of national culture (uncertainty avoidance and power distance) on the adoption of a type of IT infrastructure (frame relay). A multinational survey was carried out, and it yielded useable responses from 153 businesses from 24 countries. The results demonstrated that businesses from higher uncertainty avoidance countries were less likely to adopt frame relay. A one-point increase in Hofstedes uncertainty avoidance index for the country of incorporation was associated with a 3% lower likelihood of adopting frame relay. Power distance was not significantly correlated with adoption of frame relay. These results highlight the relevance of dimensions of national culture as factors affecting corporate adoption of IT infrastructure. Implications for practice and further research are presented.

The role of IT in successful knowledge management initiatives

Executives must confront the challenging task of deciding the type of IT to deploy in support of their knowledge management initiatives.

Organizational transformation using electronic data interchange: the case of tradenet in Singapore

This study illustrates how electronic data interchange (EDI) could be used in conjunction with organizational transformation to generate phenomenal gains in organizational efficiency and effectiveness. It reviews the current literature on information-technology-enabled organizational transformation to identify key variables for measuring organizational change. It employs the case research method to examine TradeNet, a well-established EDI system in Singapore. It discusses how the Trade Development Board (TDB) of Singapore has taken advantage of the TradeNet opportunity to drastically transform its own organizational structure, business processes, business network, and business scope. The organizational transformation that accompanied TradeNet implementation resulted in significant gains for both the public and the private sector in Singapore. TDB and other public-sector organizations gained in terms of increased productivity in carrying out their organizational functions. The trading community, comprising the private-sector organizations, benefited in terms of increased competitiveness. Change-point analyses carried out on annual organizational and performance figures confirmed the productivity increases at TDB. Analyses of the results of questionnaires administered to TradeNet participants confirmed the increased competitiveness experienced by the trading community. Noteworthy lessons from this study, important for EDI implementation, are a willingness to change existing mindset, to institute radical transformation, to leverage knowledge and technology, and to foster win-win situations. This study demonstrates that the use of IT, or EDI in particular, for organizational transformation could lead to phenomenal gains.

Conceptualizing and Testing a Social Cognitive Model of the Digital Divide

The digital divide has loomed as a public policy issue for over a decade. Yet, a theoretical account for the effects of the digital divide is currently lacking. This study examines three levels of the digital divide. The digital access divide (the first-level digital divide) is the inequality of access to information technology (IT) in homes and schools. The digital capability divide (the second-level digital divide) is the inequality of the capability to exploit IT arising from the first-level digital divide and other contextual factors. The digital outcome divide (the third-level digital divide) is the inequality of outcomes (e.g., learning and productivity) of exploiting IT arising from the second-level digital divide and other contextual factors. Drawing on social cognitive theory and computer self-efficacy literature, we developed a model to show how the digital access divide affects the digital capability divide and the digital outcome divide among students. The digital access divide focuses on computer ownership and usage in homes and schools. The digital capability divide and the digital outcome divide focus on computer self-efficacy and learning outcomes, respectively. This model was tested using data collected from over 4,000 students in Singapore. The results generate insights into the relationships among the three levels of the digital divide and provide a theoretical account for the effects of the digital divide. While school computing environments help to increase computer self-efficacy for all students, these factors do not eliminate knowledge the gap between students with and without home computers. Implications for theory and practice are discussed.

Reducing status effects with computer-mediated communication: evidence from two distinct national cultures

Matching laboratory experiments were conducted in two distinct national cultures to investigate whether computer-mediated communication (CMC) can reduce status effects during group communication in both national cultures. Three independent variables were studied: national culture (Singapore versus U.S.), task type (intellective versus preference), and communication medium (unsupported versus CMC). Three different facets of status effects were measured as dependent variables: status influence, sustained influence, and perceived influence. Singapore groups reported higher sustained influence than U.S. groups. Preference task groups experienced higher status influence and sustained influence than intellective task groups. Unsupported groups also had higher status influence and sustained influence compared to CMC groups. In addition, Singapore groups that completed the preference task in the unsupported setting reported higher perceived influence than groups under other treatments. These results demonstrate that CMC appears to be able to reduce status effects during group communication, both in Singapore and in the United States. This is especially true when groups are working on a preference task. Moreover, status influence appears to be more sustainable in Singapore groups, where group members appear to be more conscious of its presence, than in U.S. groups.

Online information disclosure: Motivators and measurements

To increase their revenue from electronic commerce, more and more Internet businesses are soliciting personal information from consumers in order to target products and services at the right consumers. But when deciding whether to disclose their personal information to Internet businesses, consumers may weigh the concerns of giving up information privacy against the benefits of information disclosure. This article examines how Internet businesses can motivate consumers to disclose their personal information. Based on a synthesis of the literature, the article identifies seven types of extrinsic or intrinsic benefits that Internet businesses can provide when soliciting personal information from consumers. Through comprehensive conceptual and empirical validation processes, the article develops an instrument that allows Internet businesses to gauge the preference of consumers for the various types of benefits. By testing a set of nomological networks, some ideas are presented to Internet businesses about what types of benefits may be more effective given the personality traits of particular consumer populations. Besides providing a foundation for efforts aimed at developing theories on information, privacy and information disclosure, the results of this research provide useful suggestions to Internet businesses on how best to solicit personal information from consumers. Implications for research and practical application are discussed.
