In this paper we attempt to assess the impact of IS research on practice. It is important to show a positive impact, if we can, so that academia, prospective students and the outside world more generally sees that the IS discipline has made a positive and major impact on organizations, people and society. Our research fills a gap as there has been little or no work to date that systematically a...

This paper examines the manner by which online product information is able to change customers’ purchase intentions using theoretical and methodological specifications. For theorizing, we adopted the subjectivity/objectivity dichotomy at the epistemological level to propose quality and preferences as product evaluation criteria which determine the customers’ purchase intention. In validation, w...

Academicians and practitioners are becoming increasingly interested in the economics of Information Technology (IT). In part, this interest stems from the increased role that IT now plays in the strategic thinking of most large organizations, and from the significant dollar costs expended by these organizations on IT. Naturally enough, researchers are turning to economics as a reference discipl...

Event studies, which gauge stock market reactions to specific events or happenings that may impact a business's operations, represent a relatively new but fast growing research approach in the information systems field. Building on four earlier literature reviews, in this paper we examine seventy-three event studies dealing with information technology. The purpose of this review is to assess th...

In this response, however, I would like to take issue with some aspects of their article. First, I will argue that Jones and Karsten’s characterizations of adaptive structuration theory (AST) and the approach to research AST advocates are too narrowly drawn. Second, I will raise some questions with their contention that structures exist only as memory traces, a conclusion that has important imp...

Nonprofit organizations have become an important part of the U.S. economy, but Information Systems (IS) research in the nonprofit context has been limited so far. In this paper we argue that the nonprofit sector presents a unique context for IS research and call for more research efforts at this new frontier. In particular, we discuss the differences between nonprofit, private, and public conte...

Choice of communication media is an important topic in Information Systems research. To complement the prevailing research which focuses on the effective delivery of message through communication media, this research regards communication as a way to accomplish social exchanges. Because communication media vary in their capacity to deliver nonverbal cues, they vary in their capacity to produce ...

Industry analysts have received an increase in attention within information systems research during the past few years. Acknowledged as propagators in the diffusion of information technology (IT) innovations, they provide their clients and the neighboring industry-community with definitions, tools and frameworks intended to aid both managerial decision-making and operations. They have been desc...

Singular systems have been studied extensively during the last two decades due Abstract to their many practical applications. Such systems possess numerous properties not shared by the well-known state variable systems. This paper considers the linear tracking problem for the continuous-time singular systems. The Hamilton-Jacobi theory is used in order to compute the optimal control and associa...

This paper is concerned with the second problem. However, the methodology developed to solve the second problem provides cost information that can be used by the problem definer to assist him with the determination of the requirements. One approach to determining the requirements of an information system involves comparing the information value of a report with the cost of produoing the report....
