Investigating use continuance of data mining tools

While improving decisional quality is important to businesses, continued use of DMTs is a critical issue for managerial personnel. This problem mainly concerns the willingness of an individual to participate in the behavior. It can be further defined in a routine-based working behavior. This problem essentially involves three key issues, task fit, technology use, and habit. This study therefore integrates task-technology fit (TTF) model, expectation–confirmation mode (ECM), and habit, to examine the determinants of continued use of DMTs. Prior studies have focused on intention to use DMTs in the first time and only considered part of the three issues for identifying the determinants. 285 respondents from managerial personnel were collected to empirically evaluate this research model. The three issues are all important in influencing continuance use intention of DMTs. In particular, the task-technology fit indicates a direct effect on two factors of the technology use issue, user satisfaction and perceived usefulness, and an indirect effect on continuance use intention. User satisfaction and perceived usefulness, and habit are the key predictors of continuance use intention.

Assessing the effects of consumers’ product evaluations and trust on repurchase intention in e-commerce environments

This study enhances the existing literature on online trust by integrating the consumers’ product evaluations model and technology adoption model in e-commerce environments. In this study, we investigate how perceived value influences the perceptions of online trust among online buyers and their willingness to repurchase from the same website. This study proposes a research model that compares the relative importance of perceived value and online trust to perceived usefulness in influencing consumers’ repurchase intention. The proposed model is tested using data collected from online consumers of e-commerce. The findings show that although trust and e-commerce adoption components are critical in influencing repurchase intention, product evaluation factors are also important in determining repurchase intention. Perceived quality is influenced by the perceptions of competitive price and website reputation, which in turn influences perceived value; and perceived value, website reputation, and perceived risk influence online trust, which in turn influence repurchase intention. The findings also indicate that the effect of perceived usefulness on repurchase intention is not significant whereas perceived value and online trust are the major determinants of repurchase intention. Major theoretical contributions and practical implications are discussed.

Customer acceptance of IPTV service quality

The purpose of this article is to provide insights into the effects of Internet Protocol Television (IPTV) service quality and reveal mediation effects in the process of forming the repurchase intention. This study incorporates additional theoretical construct, perceived enjoyment, to reflect IPTV characteristics using extended technology acceptance model (TAM). This study empirically investigated a research model and conducted a survey of IPTV service users. The results of this study are as follows. First, IPTV service quality is summarized as design, security, and customer service, which is supported by second-order factor analysis. Service quality had an influence on perceived usefulness, perceived ease of use, and perceived enjoyment. Second, perceived ease of use had a significant effect on perceived enjoyment, and perceived usefulness also had an effect on repurchase intention. Third, attitude, trust, and satisfaction had a positive effect on repurchase intention. To reveal the impact on repurchase intention of the IPTV service quality, this study proposes customer acceptance on IPTV service based on a modified TAM.

What drives purchase intention in the context of online content services? The moderating role of ethical self-efficacy for online piracy

With the proliferation of online content service industry, understanding the factors affecting consumer intention to purchase online content services has become an important issue for academics and practitioners. While previous research has suggested that consumers’ perceived value and moral judgment are two main factors influencing behavioral intention to purchase online content services, few studies have explored what drives perceived value and if customers’ ethical self-efficacy will moderate the effect of perceived value on purchase intention. Thus, based on the value-based adoption model and previous literature, this study explores the antecedents of perceived value and the moderating effect of ethical self-efficacy for online piracy (ESEOP) on the relationship between perceived value and purchase intention in the context of online content services. Data collected from 124 respondents in Taiwan are tested against the research model using the partial least squares (PLS) approach. The results indicate that perceived enjoyment, perceived usefulness, perceived fee, and ESEOP have a significant influence on perceived value and that ESEOP can enhance the positive effect of perceived value on purchase intention. The findings of this study provide several important theoretical and practical implications for consumer online content purchase behaviors.     

Effects of various characteristics of social commerce (s-commerce) on consumers’ trust and trust performance

The development of social networking sites (SNSs) has given rise to a new e-commerce paradigm called social commerce (s-commerce). S-commerce is a subset of e-commerce and uses SNSs for social interactions and user contributions to facilitate the online buying and selling of various products and services. Recent years have witnessed the rapid growth of s-commerce in Korea, but this growth has involved a number of transaction-related issues such as no delivery and the delivery of wrong items. In particular, consumers’ trust has become a crucial factor in the success of s-commerce firms, requiring these firms to make more effort to gain this trust. In this regard, this study identifies the key factors in s-commerce [reputation, size, information quality, transaction safety, communication, economic feasibility, and word-of-mouth (WOM) referrals], that is, the characteristics of s-commerce influencing Korean consumers’ trust in s-commerce. In addition, the study assesses the effects of trust on trust performance (purchase intentions and WOM intentions). The results of an empirical analysis based on a sample of 371 s-commerce users indicate that all the characteristics of s-commerce (except for economic feasibility) had significant effects on trust and that trust had significant effects on purchase and WOM intentions. The results have important implications for s-commerce firms wishing to develop a successful business model for providing their customers with trustworthy services.

An investigation of consumers’ webstore shopping: A view of click-and-mortar company

Consumers’ shopping intention is central to a Webstore's success. While past information system (IS) studies have examined this phenomenon extensively, they have focused on examining the single channel of e-tailing only. Knowledge of consumers’ cross-channel shopping behavior, which is common nowadays, was scarce. This study has empirically investigated a research model proposing how consumers’ brand loyalty in the retailing channel may impact on their shopping intentions at the same brand's Webstore. Specifically, in contrast to the system approach examined by past IS studies, this study has undertaken a brand perception approach and uncovered that by shaping consumers’ online perceptions of brand familiarity and Webstore reputation, consumers’ offline brand loyalty directly and indirectly enhances their trust in Webstore and lead to a higher shopping intention. Practical suggestions for click-and-mortar companies in building their channel strategies were proposed accordingly.

The effects of trust assurances on consumers’ initial online trust: A two-stage decision-making process perspective

This research examines the effects of type and displaying phase of trust assurances on consumers’ initial trust in an online retailer. We propose a two-stage formation process of initial online trust. The main effects of trust assurances on initial trust and the interaction between type and displaying phase of trust assurances are explored. We conducted a laboratory experiment to test our hypotheses. The results demonstrate that there exist positive effects of displaying trust assurances on initial trust. In particular, general trust assurances perform better when displayed in the information-searching stage, while specific trust assurances lead to higher initial trust when displayed in the choice stage. In the context of providing trust assurances, consumers’ knowledge of trust assurances exerts a direct and positive effect on initial trust. High knowledge level of trust assurances helps to generate the advantage of displaying assurances in the right stage. These findings have several important implications for research and practice.     

Empirical observations on the session timeout threshold

The World Wide Web is a popular “tool” for companies. It can be used as a method of communication between companies and their customers; it also allows organizations to setup virtual storefronts that can be accessed by customers from all over the world. The ability to understand customers’ behavior is extremely important as companies strive to increase the usability and profitability of their web service. The concept of a session is a popular unit of measurement used to analyze recorded information. However, this concept is currently rather abstract and lacks definition. How we measure a session is a fundamental question for web services utilizing this concept. Currently, this question has no real answer. This paper presents a session timeout threshold model based on empirical observations as an initial answer to this question. The model seeks to provide accurate session data with respect to individual web services.     

The effect of site quality on repurchase intention in Internet shopping through mediating variables: The case of university students in South Korea

We performed a study to determine the influence that site quality has on repurchase intention of Internet shopping through customer satisfaction, customer trust, and customer commitment. Appropriate measures were developed and tested on 230 university students of Gyeongnam province in South Korea with a cross-sectional questionnaire survey. The results of the empirical analysis confirmed that site quality can be conceptualized as a composite of six dimensions of shopping convenience, site design, information usefulness, transaction security, payment system, and customer communication. Second, site quality positively affected customer satisfaction and customer trust, but did not affect customer commitment and repurchase intention. Third, site quality can affect repurchase intention by enhancing or attenuating customer satisfaction, customer trust, and customer commitment in online transaction situation. The mediating effect of customer satisfaction, customer trust, and customer commitment between site quality and repurchase intention is identified. Fourth, site quality indirectly affected customer commitment through customer satisfaction. Customer satisfaction indirectly affected repurchase intention through customer trust and customer commitment. Thus, it is found that site quality can be a very important factor to enhance repurchase intention in the customer perspective.
