Thistransference of systems, whether they are developed internallyor purchased in the commercial software/ hardwaremarketplace, is plagued with problems (Kwon & Zmud,1987).The ITT problem is even more acute in developingcountries, such as the emerging...

The likelihood that the firm's information systems are insufficiently protected against certain k... more The likelihood that the firm's information systems are insufficiently protected against certain kinds of damage or loss is known as "systems risk." Risk can be managed or reduced when managers are aware of the full range of controls available and implement the most effective controls. Unfortunately, they often lack this knowledge and their subsequent actions to cope with systems risk are less effective than they might otherwise be. This is one viable explanation for why losses from computer abuse and computer disasters today are uncomfortably large and still so potentially devastating after many years of attempting to deal with the problem. Results of comparative qualitative studies in two information services Fortune 500 firms identify an approach that can effectively deal with the problem. This theory-based security program includes: (1) use of a security risk planning model, (2) education/training in security awareness, and (3) Countermeasure Matrix analysis. abroad, the Local Government Audit Inspectorate (1981). Estimates of annual losses vary, but some set losses at between 500millionand500 million and 500millionand5 billion per year in the U.S. alone . If anything, losses have become even more serious as time goes on .

The tutorial is written as a teaching aid for doctoral seminars that may cover PLS and for researchers interested in learning PLS. An annotated example with data is provided as an additional tool to assist the reader in reconstructing the detailed example.

Researchers require them for theory building and testing; practitioners require them for improving organizational processes. But for IS professionals to engage in the serious creation of metrics, it is critical to recognize:(1) that the phenomenon of net-enablement is an enduring change, probably led in the future by “brick-cum-click” firms,(2) ...

We conducted an experiment involving 51 temporary virtual teams. Half of the teams were required to comply with behavior control mechanisms traditionally used in colocated teams. Their counterparts were allowed to self-direct. 1 Cynthia Beath was the accepting senior editor for this paper.

The current study combines innovation diffusion and attitude theories in a theoretical framework to examine differences in pre-adoption and post-adoption beliefs and attitudes.

Despite the number of studies targeted at explaining system usage, there are crucial differences in the way the variable has been conceptualized and operationalized. This wide variation

The article examines the two primary dyadic net-enabled relationships in the marketplace: B2C and B2B. It also considers issues that extend beyond these two relationships. B2C practice and research are analyzed from:(1) consumer,(2) service, and (3) risk perspectives. Three central issues of B2B or ...

The sample includes users of urban and rural information centers, users of cybercafes, Internet Service Providers (ISP) and their subscribers. Questionnaires will be administered to private and public sector knowledge workers. Current national IT policy documents will be gathered and coded based on Gurbaxani's theoretical framework, and IT policy makers and parties affected by IT policy will be interviewed. Our study is unique in that it: (1) focuses on the complex socio-cultural construct, extending previous research in this line of inquiry; (2) combines qualitative and quantitative methodolgies; (3) links national economic development policies and their impact on ITT, and (4) is empirical, moving beyond frameworks and propositions to offer tangible insight into the dynamic relationship between culture values, policies, implementation factors and ITT. The study has implications for research and practice. From a research perspective, this study specifically r

Questions that likely require additional attention include:(1) Where/what is the real value in substituting information for physical processes?,(2) which NE systems effectively support end-to-end fulfillment?, and (3) when should a Net-enabled organization share information? With respect to extant studies in Net-enhancement, the field has been ...

According to TAM, IT adoption is influenced by two perceptions: usefulness and ease-of-use. Research has shown that perceived usefulness (PU) affects intended adoption of IT, but has mostly failed to do so regarding perceived ease of use (PEOU). The basic proposition of this study is that this varying importance of PEOU may be related to the nature of the task. PEOU relates to assessments of the intrinsic characteristics of IT, such as the ease of use, ease of learning, flexibility, and clarity of its interface. PU, on the other hand, is a response to user assessment of its extrinsic, i.e., task-oriented, outcomes: how IT helps users achieve task-related objectives, such as task efficiency and effectiveness. Accordingly, the study theorizes that PEOU directly affects IT adoption only when the primary task for which the IT is deployed is directly associated with intrinsic IT characteris...

We contend that the alleged shortcomings of PLS are not due to problems with the technique, but instead to three problems with Rönkkö and Evermann's study: (a) the adherence to the common factor model, (b) a very limited simulation designs, and (c) overstretched generalizations of their findings. Whereas Rö nkkö and Evermann claim to be dispelling myths about PLS, they have in reality created new myths that we, in turn, debunk. By examining their claims, our article contributes to reestablishing a constructive discussion of the PLS method and its properties. We show that PLS does offer advantages for exploratory research and that it is a viable estimator for composite factor models. This can pose an interesting alternative if the common factor model does not hold. Therefore, we can conclude that PLS should continue to be used as an important statistical tool for management and organizational research, as well as other social science disciplines.

Before entering academia, he spent 12 years developing and managing large information systems, including the ongoing management of a state-of-the-art logistics system. His research specializations are: IS adoption, the Internet and Electronic Commerce, culture and gender effects, software maintenance, and trust. He won the second best conference place award for the 1996 Academy of Management Printed Papers Proceeding and has published in the IEEE Conference on Software Maintenance and ABSTRACT This study extends Davis' (1989) TAM model and Straub's (1994) SPIR addendum by adding gender to an IT diffusion model. The Technology Acceptance Model (TAM) has been widely studied in IS research as an explanation of the use of information systems across IS-types and nationalities. While this line of research has found significant cross-cultural differences, it has ignored the effects of gender, even though in socio-linguistic research, gender is a fundamental aspect of culture. Indeed, sociolinguistic research that has shown that men tend to focus discourse on hierarchy and independence while women focus on intimacy and solidarity. This literature provides a solid grounding for conceptual extensions to the IT diffusion research and the Technology Acceptance Model.
