Breaking the Ice in B2C Relationships: Understanding Pre-Adoption E-Commerce Attraction. (Information Systems Research, 2013)
Authors: Abstract:
    This research proposes that the forming of a business-to-consumer (B2C) customer relationship is part of a multiphased technology adoption process where attraction is the first step in this sequence. A conceptual model, called the electronic commerce (e-commerce) attraction model (eCAM), offers a theoretical foundation for guiding two empirical studies (N D345 and N D240, respectively) investigating how initial customer perceptions of a website influence attraction toward this website. The results support the eCAM as a new theoretical lens for understanding electronic commerce-based attraction. Comparisons are made between the proposed eCAM and previously established adoption models (i.e., the Technology Acceptance Model and WebQual) as well as the discriminant validity of the constructs in these models. Results demonstrate that the eCAM provides additional insights for understanding how website design influences e-commerce attraction and adoption. The implications of these results for future research and website design are discussed.
MEDIA SELECTION AS A STRATEGIC COMPONENT OF COMMUNICATION. (MIS Quarterly, 2013)
Authors: Abstract:
    Why do people select the media they choose for a particular type of communication? The media choice literature has considered myriad contextual factors that influence media choice, from proximity of the communication partners, to the urgency of the situation, to time pressure, and so on. From this body of work, a contingency-based theory of media choice has emerged. An alternative approach is to investigate how communication strategies and media characteristics affect choice. We identified two approaches for investigating these issues: Te'eni's (2001) model of organizational communication and Dennis et al.'s (2008) media synchronicity theory. Using a scenario-based methodology, we asked respondents which medium they would use for a deceptive communication task and why they made that choice. We analyzed the data from the perspective of both the Te'eni and MST frameworks, enabling us to compare the extent to which each was able to explain our respondents' media choices. Both frameworks, at differing levels of communication granularity, suggest that the intent of the communication drives a strategy that ultimately informs media choice. The results suggest that the prior contingency-based explanations of media choice could be improved by not only understanding the intent of the communication, but also the strategy used by an individual to execute this communication. Additionally, we found that the more finely grained view of communication contained in MST explained more of the outcomes and was more parsimonious as well.
WHAT SIGNAL ARE YOU SENDING? HOW WEBSITE QUALITY INFLUENCES PERCEPTIONS OF PRODUCT QUALITY AND PURCHASE INTENTIONS. (MIS Quarterly, 2011)
Authors: Abstract:
    The article presents marketing management research on the impact of Web site design influences consumer behavior in electronic commerce. Signalling theory is employed to consider if the perception of Web site quality by consumers influences their perceptions of product quality and their purchasing decisions in electronic commerce. Web site quality perceptions were found to have a significant correlation to product quality perception and purchasing decisions, and a greater influence on perceived product quality when consumers had higher information asymmetries.
AN ALTERNATIVE TO METHODOLOGICAL INDIVIDUALISM: A NON-REDUCTIONIST APPROACH TO STUDYING TECHNOLOGY ADOPTION BY GROUPS. (MIS Quarterly, 2010)
Authors: Abstract:
    Studies on groups within the MIS discipline have largely been based on the paradigm of methodological individualism. Commentaries on methodological individualism within the reference disciplines suggest that studies embracing this paradigm can lead to potentially misleading or incorrect conclusions. This study illustrates the appropriateness of the alternate non-reductionist approach to investigating group-related phenomenon, specifically in the context of technology adoption. Drawing on theories of group influence, prior research on conflict, technology characteristics, task- technology fit, group communication media, and recent theoretical work surrounding group technology adoption, the paper proposes and empirically tests a new non-reductionist model for conceptualizing technology adoption by groups. Further, the study also empirically compares this nonreductionist model with a (hypothetical) methodological individualist model of technology adoption by groups. Results strongly support most of the assertions of the non-reductionist model and highlight that this model provides a more robust explanation of technology adoption by groups than a methodological individualist view. Further, the study also highlights some conditions wherein the methodological individualist view fails to provide correct explanations. The implications of the study's findings for future research are discussed.
The Influence of Website Characteristics on a Consumer's Urge to Buy Impulsively. (Information Systems Research, 2009)
Authors: Abstract:
    With the proliferation of e-commerce, there is growing evidence that online impulse buying is occurring, yet relatively few researchers have studied this phenomenon. This paper reports on two studies that examine how variations in a website influence online impulse buying. The results reveal some relevant insights about this phenomenon. Specifically, although many participants had the urge to buy impulsively, regardless of website quality, this behavior's likelihood and magnitude was directly influenced by varying the quality of taskrelevant and mood-relevant cues. Task-relevant cues include characteristics, such as navigability, that help in the attainment of the online consumer's shopping goal. Conversely, mood-relevant cues refer to the characteristics, such as visual appeal, that affect the degree to which a user enjoys browsing a website but that do not directly support a particular shopping goal. The implications of the results for both future research and the design of human-computer interfaces are discussed.
UNCOVERING THE INTELLECTUAL CORE OF THE INFORMATION SYSTEMS DISCIPLINE. (MIS Quarterly, 2008)
Authors: Abstract:
    What is the intellectual core of the information systems discipline? This study uses latent semantic analysis to examine a large body of published IS research in order to address this question. Specifically, the abstracts of all research papers over the time period from 1985 through 2006 published in three top IS research journals--MIS Quarterly, Information Systems Research, and Journal of Management Information Systems--were analyzed. This analysis identified five core research areas: (1) information technology and organizations; (2) IS development; (3) IT and individuals; (4) IT and markets; and (5) IT and groups. Over the time frame of our analysis, these core topics have remained quite stable. However, the specific research themes within each core area have evolved significantly, reflecting research that has focused less on technology development and more on the social context in which information technologies are designed and used. As such, this analysis demonstrates that the information systems academic discipline has maintained a relatively stable research identity that focuses on how IT systems are developed and how individuals, groups, organizations, and markets interact with IT.
MEDIA, TASKS, AND COMMUNICATION PROCESSES: A THEORY OF MEDIA SYNCHRONICITY. (MIS Quarterly, 2008)
Authors: Abstract:
    his paper expands, refines, and explicates media synchronicity theory, originally proposed in a conference proceeding in 1999 (Dennis and Valacich 1999). Media synchronicity theory (MST) focuses on the ability of media to support synchronicity, a shared pattern of coordinated behavior among individuals as they work together. We expand on the original propositions of MST to argue that communication is composed of two primary processes: conveyance and convergence. The familiarity of individuals with the tasks they are performing and with their coworkers will also affect the relative amounts of these two processes. Media synchronicity theory proposes that for conveyance processes, use of media supporting lower synchronicity should result in better communication performance. For convergence processes, use of media supporting higher synchronicity should result in better communication performance. We identify five capabilities of media (symbol sets, parallelism, transmission velocity, rehearsability, and reprocessability) that influence the development of synchronicity and thus the successful performance of conveyance and convergence communication processes. The successful completion of most tasks involving more than one individual requires both conveyance and convergence processes, thus communication performance will be improved when individuals use a variety of media to perform a task, rather than just one medium.
Publication Opportunities in Premier Business Outlets: How Level Is the Playing Field? (Information Systems Research, 2006)
Authors: Abstract:
    This paper reports an analysis of the proportion of faculty publishing articles in premier business journals (i.e., the ratio of authors of premier business journal articles to total faculty of a discipline) across the disciplines of accounting, finance, management, marketing, and information systems (IS) for the years 1994─2003. This analysis revealed that over this period the management discipline had on average the highest proportion of faculty publishing in premier journals (12.7 authors per 100 management faculty), followed by finance (9.4 authors per 100 faculty), marketing (9.2 authors per 100 faculty), IS (5.5 authors per 100 faculty), and accounting (4.8 authors per 100 faculty). A further analysis examined these ratios for the different disciplines over time, finding that the ratios of authors to faculty have actually decreased for the disciplines of marketing and IS over this time period but have remained stable for the disciplines of accounting, management, and finance. Given steady growth in faculty size of all disciplines, the proportion of faculty publishing articles in premier journals in 2003 for all disciplines is lower than their 10-year averages, with IS having the lowest proportion in 2003. A sensitivity analysis reveals that without substantial changes that would allow more IS faculty to publish in the premier journals (e.g., by increasing publication cycles, number of premier outlets, and so on), IS will continue to lag far below the average of other disciplines. The implications of these findings for IS researchers, for institutions and administrators of IS programs, and for the IS academic discipline are examined. Based on these implications, recommendations for the IS discipline are presented.
RESEARCH STANDARDS FOR PROMOTION AND TENURE IN INFORMATION SYSTEMS. (MIS Quarterly, 2006)
Authors: Abstract:
    What constitutes excellence in information systems research for promotion and tenure? This is a question that is regularly addressed by members of promotion and tenure committees and those called upon to write external letters. While there are many elements to this question, one major element is the quality and quantity of an individual's research publications. An informal survey of senior Information Systems faculty members at 49 leading U.S. and Canadian universities found 86 percent to expect three or more articles in elite journals. In contrast, an analysis of publication performance of Ph.D. graduates between the years of 1992 and 2004 found that approximately three individuals in each graduating year of Ph.D.s (about 2 percent) published 3 or more articles in a set of 20 elite journals within 6 years of graduation. Only 15 individuals from each graduating year (11 percent) published one or more articles. As a discipline, we publish elite journal articles at a lower rate than Accounting, yet our promotion and tenure standards are higher, similar to those of Management, Marketing, and Finance. Thus, there is a growing divergence between research performance and research standards within the Information Systems discipline. As such, unless we make major changes, these differences will perpetuate a vicious cycle of increasing faculty turnover, declining influence on university affairs, and lower research productivity. We believe that we must act now to create a new future, and offer recommendations that focus on the use of more appropriate standards for promotion and tenure and ways to increase the number of articles published.

Information Is What You Make of It: The Influence of Group History and Computer Support on Information Sharing, Decision Quality, and Member Perceptions. (Journal of Management Information Systems, 1998)
Authors: Abstract:
    Researchers have proposed that the contradictions observed between past group support system (GSS) laboratory and field research may be partially accounted for by the ad-hoc nature of the groups that are often used in the laboratory. To examine this, a laboratory experiment examining the influence of group history (i.e., established versus ad-hoc groups) and the level of computer support (i.e., communicating via a computer-mediated system versus face-to-face) was conducted. Dependent variables examined in the research include information-sharing performance, decision quality, and member perceptions. Subjects completed a hidden profile task--a task where some information is held by all group members prior to the meeting, while other information is held only by a subset of the group. As expected, established groups discussed less unique information than ad-hoc groups. In addition, information sharing was positively related to the quality of group decisions. Members of established groups were more satisfied than members of ad-hoc groups; members using the computer-mediated system were less satisfied than those communicating face-to-face. In addition, group cohesion was positively related to satisfaction and decision quality. The results are discussed in the context of prior theory and research. Opportunities for future research are also described.
Research Report: The Effectiveness of Multiple Dialogues in Electronic Brainstorming. (Information Systems Research, 1997)
Authors: Abstract:
    Members of brainstorming groups often pursue the same set of ideas rather than considering a wide and diverse range of ideas, which may reduce the number of ideas they produce. One way to reduce this cognitive inertia may be to encourage groups to engage in several simultaneous discussions or dialogues. This experiment, which studied groups brainstorming electronically, found that groups generated more ideas, more high-quality ideas, and more novel ideas when using multiple dialogues than when using single dialogues.
Process Structuring in Electronic Brainstorming. (Information Systems Research, 1996)
Authors: Abstract:
    One aspect of brainstorming that has received little research attention is how the brainstorming problem should be presented to the group, whether as one all-encompassing question or as a series of separate questions each focusing on one aspect of the problem. This paper reports the results of two experiments in which subjects (MBAs in the first, senior executives in the second) electronically brainstormed on intact problems (where all parts of the problem were presented simultaneously) or on decomposed problems (where three subcategories of the problem were sequentially posed to the groups). In both experiments, groups using the decomposed process generated 60% more ideas. We attribute these differences to the ability of time constraints to increase the rate of idea generation, and the ability of problem decomposition to refocus members' attention more evenly across the entire problem.
Facilitation, GSS, and Training as Sources of Process Restrictiveness and Guidance for Structured Group Decision Making: An Empirical Assessment. (Information Systems Research, 1996)
Authors: Abstract:
    Structured decision techniques have been a mainstay of prescriptive decision theory for decades. Group Support Systems (GSSs) automate many of the features found in decision techniques, yet groups often choose to ignore both the technique and the technology in favor of more familiar decision processes. This research empirically tests propositions and hypotheses for a specific instantiation of Adaptive Structuration Theory. A controlled laboratory experiment tests the ability of three appropriation mediators (e.g., facilitation, GSS configuration, and training) to directively affect group decision making through guidance and restrictiveness. The experiment used a hidden-profile task and structured decision technique which directed group members to reach a decision by identifying the problem, choosing criteria, and selecting a solution. The results supported the proposition that appropriation mediators can increase the faithful use of structured decision techniques and that faithful use can improve decision quality.
Using IT to Reengineer Business Education: An Exploratory Investigation of Collaborative Telelearning. (MIS Quarterly, 1995)
Authors: Abstract:
    This longitudinal field study (three work sessions plus an initial training session) investigates the efficacy of a new technology-desktop video- conferencing (DVC)-in support of collaborative telelearning (i.e., collaborative learning among non-proximate team members). Two types of collaborative telelearning environments are considered: One involves local groups (i.e., students on the same campus), and the other involves non-proximate distant groups (La. students on two separate campuses). The collaborative telelearning environments are compared to each other and to a traditional face-to-face collaborative learning environment. The study found that the three environments are equally effective in terms of student knowledge acquisition; however, higher critical-thinking skills were found in the distant DVC environment. The subjects in the three learning environments were equally satisfied with their learning process and outcomes. At the conclusion of the longitudinal assessment, the distant students using DVC were more committed and attracted to their groups compared to local students who worked face-to-face or through DVC.
IS'95: Guideline for Undergraduate IS Curriculum. (MIS Quarterly, 1995)
Authors: Abstract:
    This paper provides an overview report of the first joint curriculum development effort for undergraduate programs in information systems. The curriculum recommendations am a collaborative effort of the following organizations: ACM, AIS, DPMA, and ICIS. After a summary of the objectives and rationale for the curriculum, the curriculum model is described. Input and output attributes of graduates are delineated. Resource requirements for effective IS programs are then identified. Lastly, there is a proposal for maintaining currency of the curriculum through electronic media.
A Mathematical Model of Performance of Computer-Mediated Groups during Idea Generation. (Journal of Management Information Systems, 1994)
Authors: Abstract:
    As the use of computer-mediated systems for group work grows, the need for a better understanding of the impact of such systems becomes more important. Studies of non-computer-mediated group work have long been guided by mathematical models of group interaction and performance, but recent research suggests that these models do not fit the unique capabilities of computer-mediated systems. This article builds on Previous group research to create a mathematical model of computer-mediated group performance which is then tested using data from two prior studies. This testing enabled us to conclude that models of computer-mediated groups run counter to the many guiding models of non-computer-mediated groups. We therefore discuss the implications of these differences in relation to users of this technology and to future developmental and empirical research.
