Informational and Normative Social Influence in Group-Buying: Evidence from Self-Reported and EEG Data (Journal of Management Information Systems, 2014)
Authors: Abstract:
    This study examines two types of information commonly used by group-buying sites to induce purchasing. The first study indicates the number of people who have bought a deal ("buy" information). The second one indicates Facebook friends who "like" a deal ("like" information). The effects of the group-buying information on opinions (attitude and intention) and emotions were examined using a controlled experiment. Our results show that positive and negative "buy" information has an asymmetric influence on attitude and intention, whereas "like" information has a positive influence on intention. The presence of "buy" information is associated with EEG activity that is generally linked to negative emotions. However, the addition of "like" information is associated with EEG activity that is generally linked to positive emotions. The different effects of the two types of group-buying information can be explained by the different social influences exerted by the information.
Classifying, Measuring, and Predicting Users Overall Active Behavior on Social Networking Sites (Journal of Management Information Systems, 2014)
Authors: Abstract:
    Although understanding the role of users’ overall active behavior on a social networking site (SNS) is of significant importance for both theory and practice, the complexity and difficulty involved in measuring such behavior has inhibited research attention. To understand users’ active behaviors on an SNS, it is important that we identify and classify various types of online behaviors before measuring them. In this paper we holistically examine users’ active behaviors on an SNS. Toward this end, we conduct three studies. First, we classify active behaviors on an SNS into four categories using the Delphi method. Then, we develop a measurement model and validate it using the data collected from an online survey of 477 SNS users. The measures of the developed instrument exhibit satisfactory reliability and validity and are used as indicators of the latent constructs. This instrument is then used in a predictive model based on commitment theory and tested using data from 1,242 responses. The results of data analysis suggest that affective commitment and continuance commitment are good predictors of overall active behavior on an SNS. This study complements the existing research on social media, cocreation, and social commerce. Most important, this study provides a theoretically sound measurement instrument that addresses the complex characteristic of overall active behavior on an SNS and which should be useful for future research. The findings of this study have important implications for practice as they highlight managing and stimulating users’ active behaviors on an SNS.
Factors Affecting the Adoption of Open Systems: An Exploratory Study. (MIS Quarterly, 1997)
Authors: Abstract:
    Advocates of open systems believe that problems related to compatibility, interoperability, scalability, and efficient use of IT resources can be resolved by setting software and hardware standards and strictly adhering to these standards in systems development and management. Representing a major departure from the traditional way of running an IS operation, the adoption of open systems has major ramifications on the IT infrastructure with long-lasting effects. Unfortunately, little research has been done to study this ubiquitous phenomenon despite its impacts on organizational computing worldwide. To fill this research gap, a model that incorporates seven factors perceived to affect the adoption is developed and tested. In-depth interviews with senior executives responsible for managing corporate IS functions from 89 organizations were conducted to collect data for empirical analysis. The findings suggest that organizations tend to (1) focus more on their "ability to adopt" than on the "benefits from adoption," and (2) take a "reactive" rather than "proactive" attitude in adopting open systems technology. Managerial implications are also discussed.
An Empirical Assessment of a Modified Technology Acceptance Model. (Journal of Management Information Systems, 1996)
Authors: Abstract:
    The technology acceptance model (TAM) is one of the most influential research models in studies of the determinants of information systems/information technology (IS/IT) acceptance. In TAM, perceived usefulness and perceived ease of use are hypothesized and empirically supported as fundamental determinants of user acceptance of a given IS/IT. A review of the IS and psychology literature, however, suggests that perceived usefulness can be of two distinct types: near-term usefulness and long-term usefulness. This paper reviews the concept of perceived usefulness and modifies TAM to include the two types of perceived usefulness. Data collected from nearly 285 administrative/clerical staff in a large organization were tested against the modified model using the structural equation modeling approach. The results of the study showed that, even though perceived near-term usefulness had the most significant influence on the behavioral intention to use a technology, perceived long-term usefulness also exerted a positive, though lesser, impact. No significant, direct relationship was found between ease of use and behavioral intention to use a technology. Implications of the findings and future research areas are discussed.
