Research paper thumbnail of (2006). "Online payment gateways used to facilitate e-commerce transactions and improve risk management," Communications of the Association for Information Systems

Communications of the Association for Information Systems, Jan 1, 2006

As online transactions continue to increase and become a significant part of the global economy, ... more As online transactions continue to increase and become a significant part of the global economy, the ability to accept payments online becomes more important for businesses. This paper evaluates the literature and provides current information for IS researchers and instructors focusing on electronic commerce. In this paper, we explore the components of e-credit providers (conventional, person-to-person, and third-party) and explain how each system processes a single transaction. We then analyze several market leaders in each segment and summarize the strengths and weaknesses of each company. We provide guidelines for selecting an e-credit provider and highlight the options that apply best to online businesses. Finally, we outline potential areas of future research and provide a simple tutorial on creating a business account with PayPal website Payments Standard as an example of an online payment provider.

Research paper thumbnail of Evaluating Journal Quality and the Association for Information Systems Senior Scholars' Journal Basket Via Bibliometric Measures: Do Expert Journal Assessments Add Value?

MIS Quarterly, 2013

Over the years, numerous approaches have been used to rank IS journals, approaches such as citation metrics, school lists, acceptance rates, and expert assessments. However, the results of these approaches often conflict due to a host of validity concerns. In the current scientometric study, we make significant strides toward correcting for these limitations in the ranking of mainstream IS journals. We compare expert rankings to bibliometric measures such as the ISI Impact Factor™, the h-index, and social network analysis metrics. Among other findings, we conclude that bibliometric measures provide very similar results to expert-based methods in determining a tiered structure of IS journals, thereby suggesting that bibliometrics can be a complete, less expensive, and more efficient substitute for expert assessment. We also find strong support for seven of the eight journals in the Association for Information Systems Senior Scholars' "basket" of journals. A cluster analysis of our results indicates a twotiered separation in the quality of the highest quality IS journals-with MIS Quarterly, Information Systems

New tools such are needed for rapid, noninvasive and possibly unobtrusive detection of deception and hostile intent. This paper reports five novel instrumented approaches to credibility assessment being investigated in a multi-institution research program. These instruments do not require physical contact with humans and

Through a survey of academic experts, we asked respondents to rate the top overall journals, business communication journals, technical communication journals, and the top journals from a technology perspective. In addition, we asked respondents to list the journals that they read most frequently. We analyzed the results by breaking down the rankings into world regions and ...
