To online businesses, this commerce channel also allows them to have almost non-stop accessibility to a large population of mobile device users. This study examines the factors affecting intention to use contemporary mobile commerce on the basis of integrating perceived security, subjective norm, innovativeness, and self-efficacy into the TAM model. Statistical analysis results show that self-efficacy and innovativeness are positively related to perceived ease of use. Perceived ease of use has a positive effect on perceived usefulness. Perceived ease of use, perceived usefulness, perceived security, and subjective norm have a positive relationship with intention to use mobile commerce. The theoretical and practical implications are discussed. Finally, future research directions are outlined.Item Factors influencing intention to use online consumer reviews: The case of Vietnam(2023) Pham, Long; Klaus, Tim; Changchit, ChuleepornOnline consumer reviews have been shown to play an important role that can influence consumers’ attitudes, behaviors, and purchasing decisions. This study seeks to understand factors that affect user intention to use online consumer reviews. To examine this area, this paper theorizes multiple constructs that may influence intention to use. The subjects in this study were 466 online Vietnamese consumers. The data were analyzed using structural equation modeling, and five of the seven hypotheses were found to be significant. This study found several results not found in prior studies. The construct perceived online review importance is found to be important in influencing intention to use online reviews. Both perceived usefulness and perceived credibility influenced consumers’ perceptions on the importance of online reviews. The study findings contribute to the research field of online consumer reviews and provide new insights into intention to use online consumer reviews for a developing country, different from prior studies that have focused on developed countries.Item Sandbox environments in an ERP system context: Examining user attitude and satisfaction(EJISE, 2/1/2020) Klaus, Tim; Changchit, ChuleepornEnterprise Resource Planning (ERP) systems are large complex software packages that are widely used in organizations today. Due to the complexity, sandbox environments are often used for training on ERP systems. This study examines the effectiveness of training using a sandbox environment, specifically examining user attitudes, users’ perception of financial knowledge gained, and user satisfaction in the ERP environment while learning financial concepts. The theoretical framework is based on the Technology Acceptance Model with additional factors predicted to impact users’ attitude and satisfaction. Data were collected from 124 subjects who voluntarily participated in the study. Structural Equation Modeling was used to analyze the data. The results of this study should help organizations understand the factors impacting user attitudes on ERP training leading to higher self-perception of knowledge gains and task completion satisfaction. In addition, this study provides the results of using ERP systems as a tool for financial education.Item Using customer review systems to support purchase decisions: A Comparative study between the U.S. and Thailand(Journal of Global Information Management, 2021) Changchit, Chuleeporn; Klaus, Timothy; Treerotchananon, Alicha; Changchit, Chuleeporn; Klaus, Timothy; Treerotchananon, AlichaOnline reviews have emerged as influential sources of information that greatly affect customers’ prepurchase decisions. Some studies have found that culture impacts online reviews, but many aspects of online review usage are still not well-understood. This study seeks to understand what factors influence the usage of online reviews and consumers’ intention to use online reviews influenced by culture. This study collects data from U.S. and Thai consumers to examine what factors affect user attitudes and intentions. Structural equation modeling is used to analyze the data, and the findings reveal that most of the proposed factors influence online review adoption for these two nationalities. One significant difference was found between the respondents of the two countries. The results should help online businesses gain a better understanding of these factors and thus direct their efforts to develop features that positively influence online review usage.
