This study examines the relationships between e-government service quality, perceived value, satisfaction, and loyalty toward e-government services. Survey data were collected from 340 randomly selected e-government service users in Vietnam. The results reveal that (1) e-government service quality consists of five dimensions: ease of interaction, fulfillment, citizen care, security and privacy, and trustworthiness; (2) among the five dimensions of e-government service quality, only trustworthiness and fulfillment are significantly related to perceived value; however, trustworthiness has a stronger association with perceived value than does fulfillment; and (3) both perceived value and satisfaction are positively associated with loyalty. The results indicate that the e-government can create value for the citizens by improving service quality, which may help satisfy citizens’ needs and build their loyalty.

Using the Information–Motivation–Behavioral Skills (IMB) model as a theoretical framework, we examine the direct effects of knowledge, attitude, and subjective norms on young women’s intention toward purchasing green cosmetics, and whether self-efficacy mediates these effects. Data were collected from 433 young female consumers and analyzed using the PROCESS macro for SPSS. Green-cosmetics-related knowledge and motivation (attitude and subjective norms) were positively related to green cosmetics purchase intention. Self-efficacy partially mediated the effects of knowledge, attitude, and subjective norms on purchase intention. The IMB model offers a useful framework for understanding the factors affecting young Vietnamese women’s intention toward purchasing green cosmetics. Marketers promoting green cosmetics should aim to increase consumers’ confidence in comprehending their products.

Mobile commerce is the next generation of electronic commerce that allows consumers to perform many transactions via a mobile phone instead of a desktop computer. 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.

As smartphone ownership rapidly expands, mobile payment options are gaining popularity due to the portability and convenience they offer. This study examines attitudes towards adopting mobile payment, focusing on the component risk, which consists of multiple dimensions including performance, financial, time, psychological, and social risks. The study uses a quantitative approach, collecting data through a survey distributed to mobile payment users, with 361 respondents in the United States. The survey instrument includes measures of performance and psychological risk, as well as attitudes towards mobile payment acceptance. Data analysis using SPSS 25.0 and AMOS 24.0 reveals that both performance and psychological risk significantly negatively impact attitudes towards mobile payment acceptance, underscoring the importance of mobile payment service providers implementing effective risk management policies to improve users’ positive attitudes towards their platforms.

This study explores the relationship between customer satisfaction and loyalty in mobile banking, emphasizing the moderating role of Technology Readiness. As mobile banking becomes increasingly central to financial service delivery, understanding the nuanced drivers of customer loyalty is essential for strategic growth. Drawing from the Technology Readiness Index, this study examines how four dimensions, optimism, innovativeness, discomfort, and insecurity, moderate the satisfaction–loyalty linkage. Data were collected via a structured survey from 258 mobile banking users in the United States, analyzed using partial least squares structural equation modeling (PLS-SEM). Results show that optimism and innovativeness positively moderate this relationship, while discomfort and insecurity act as negative moderators. Practically, this research introduces a segmented approach to mobile banking service design, underscoring the need for differentiated strategies that address varying levels of user readiness. Theoretically, this study addresses a gap in mobile banking literature by shifting the focus from adoption to sustained usage and satisfaction-based loyalty, enriching the discourse on customer behavior in digital finance.

ChatGPT, a generative AI chatbot, has seen unprecedented adoption, yet the factors driving its acceptance among students remain underexplored. This study investigates key determinants of U.S. university students' intention to use ChatGPT in higher education. Drawing on the technology acceptance model, theory of reasoned action, and diffusion of innovation theory, survey data from 411 students were collected and analyzed using partial least squares structural equation modeling. The results indicate that perceived usefulness and subjective norm have significant positive effects on students' intention to use ChatGPT, and perceived ease of use and trust exert indirect effects through perceived usefulness. The model explains approximately 51 % of the variance in usage intention. As one of the first empirical studies on ChatGPT adoption in education, this research extends technology acceptance theories to generative AI and offers insights for theory and educational practice.
