The Role of Impulsiveness in a TAM-Based Online Purchasing Behavior

Xiaoni Zhang; Victor R. Prybutok; Chang E. Koh

This article investigates consumer online purchasing behavior using an augmented Technology Acceptance Model. Particularly, we posit that Web use leads to intention to purchase online. Impulsiveness, Web use, and subjective norm are included in the model to test several hypotheses concerning online consumer beliefs, intentions, and the effect of psychological traits. We developed a survey instrument to collect data and used structural equation modeling to validate the research model. All of our hypotheses were confirmed except the one that links subjective norm and online buying behavior. The positive relationship between consumer impulsiveness and online purchasing behavior suggests that online stores should design their Web sites to attract impulse purchases.

Investigating factors affecting social presence and user satisfaction with Mobile Instant Messaging

Solomon Ogara; Chang E. Koh; Victor R. Prybutok

What are the drivers of social presence and user satisfaction with Mobile Instant Messaging?Survey method used to collect data.Data analysis using PLS.Social presence is influenced by user experience, richness and social influence.User satisfaction is influenced by user experience, richness and social presence. The purpose of this study is to examine the factors that influence social presence and user satisfaction with Mobile Instant Messaging (mIM). The proposed research model integrates channel expansion, social influence, social presence and media richness theories, to explain how user experience, social influence, and medium richness influence social presence and user satisfaction with mIM. A total of 239 students from a state university in the US participated in this study. Data was collected via a web-based survey. The results suggest that user experience, social influence, and perceived richness are important drivers for social presence and user satisfaction in mIM. The implications of the study findings are discussed in the paper.

Measuring e-government readiness

Chang E. Koh; Victor R. Prybutok; Xiaoni Zhang

We proposed a way of assessing readiness of a government organization to transform itself into a provider of fully integrated e-government services. We identified major components of e-government and discussed how it could evolve from a simple website into a fully integrated portal that delivers services to the public. Drawing upon strategic IS theory, we proposed three levels - strategic, system, and data - at which the governmental offices readiness for e-government should be addressed. We empirically tested our model of e-government readiness with data collected from a U.S. municipal government. However, the results supported only a two-level model rather than the three we had theorized. This finding had important implications because it supported our contention that discrepancies can occur when e-government initiatives are at a relatively early stage and some critical e-government issues have not yet emerged.

The importance of strategic readiness in an emerging e‐government environment

Chang E. Koh; Victor R. Prybutok; Sherry D. Ryan; Bashorat Ibragimova

Purpose – The purpose of the study is to examine how information technology, strategic planning processes, and people interact in an emerging e‐government environment.Design/methodology/approach – A discriminant model was developed to test the ability to distinguish between the perceptions of high and low importance of six major e‐government functions as a function of a four‐item strategic e‐government readiness scale. An empirical study of a municipal government supported the discriminant model.Findings – Government agencies must evaluate how strategic e‐government plans are developed, communicated, and integrated into the work environment. Without the proper understanding of the importance of e‐government initiatives, employees do not place high value on e‐government initiatives.Research limitations/impli‘cations – This study focuses on one group of stakeholders, employees. Future studies might consider other interested parties, like citizens, business partners, and other government organizations. Futur...

RFID implementation strategy: perceived risks and organizational fits

Se Hun Lim; Chang E. Koh

Purpose – The purpose of this paper is to investigate how organizations perceive the impact of radio frequency identification (RFID) on business performance in relation to the perceived technology‐organization fit and the perceived risk of the technology.Design/methodology/approach – A survey is conducted with professionals involved in RFID implementation initiatives in their organizations. The survey results in usable responses from 350 firms. The survey instrument consists of questions for demographics, organizational fit factors, risk factors, and expected performance measures.Findings – The results suggest that management of organizational fit factors in connection with perceived risk levels has a significant effect on the perceived impact of RFID on business performance.Research limitations/implications – The sampling process is not completely scientific and random. As a result, some findings may not be applicable to the general population. Another limitation of the paper is that most research constr...

IS journal review process: a survey on IS research practices and journal review issues

Chang E. Koh

Journal publication is an important indicator of research productivity for individual researchers as well as academic institutions. It is also a contentious issue as various stakeholders have different and often conflicting interests and perspectives. This study explores how IS researchers view journal review and publication process based on their professional status, institutional mission, and role orientation. It also investigates publication practices of IS researchers, such as frequency of article submissions, acceptance/rejection rates, number of revisions required before publication, and publication outlets.

A value chain perspective of internet practices, e‐readiness and organizational performance: A comparison of US and South Korean firms

Chang E. Koh; Kyungdoo “Ted” Nam; Victor R. Prybutok; Seogjun Lee

Purpose – The internet has become a ubiquitous technology for business and it possesses the potential to make the concept of value chain into a more attainable reality. The purpose of this paper is to conjecture that the way the internet is utilized and the extent to which the internet impacts business performance vary from country to country. The paper aims to compare two countries regarding the pattern of internet utilization, the impact of the internet on organizational performance, and the readiness for the internet from the value chain perspective.Design/methodology/approach – A survey study was conducted with CIOs and IS directors in the USA and South Korea. A research instrument was developed by adopting and revising two existing instruments on IT value chain and on business internet practices.Findings – The findings suggest that the two countries are more similar in the way they utilize the internet than anticipated despite discernable differences observed in some areas of internet utilization. Th...

A nomological model of RFID privacy concern

Yu Andy Wu; Victor R. Prybutok; Chang E. Koh; Bartlomiej Hanus

Purpose – Radio frequency identification (RFID) can bring a lot of benefits to supply chain management. However, privacy issues caused by RFID surface constantly and can impede widespread implementation of RFID. The purpose of this paper is to propose a theoretical model to explicate the construct of concern for information privacy (CFIP).Design/methodology/approach – The authors review and synthesize the extant and pertinent literature on RFID and privacy issues. Starting with previous theorization of CFIP, its four constituent dimensions are examined – collection, unauthorized secondary use, improper access, and errors – within the context of RFID‐related privacy issues.Findings – The authors situate CFIP within a nomological model, which advances that: awareness of the RFID technology itself, awareness of information security risks entailed by RFID use, and awareness of privacy protective measures are direct antecedent to CFIP; and CFIP directly influences a persons trust in the RFID technology.Social...
