This study aims to explore students’ perceptions of the use of an artificial intelligence-generated content avatar (AIGC avatar) within a learning management system (LMS).

This qualitative research involved seven postgraduate students. Data were collected through individual, in-depth interviews. The videos of the AIGC avatar, created using Leonardo, ChatGPT and Heygen, were uploaded to the LMS to communicate with students for the purposes of a welcome note, assignment guide, assignment feedback, tutorial reminders and preparation as well as to provide encouragement and study tips. Students were interviewed at the end of the semester.

The findings of this study indicated that the majority of participating students held positive perceptions regarding the use of the AIGC avatar in the LMS. They reported that it enhanced their perceived instructor’s social presence and motivation to learn. The assignment guide and feedback were particularly valued by the participants. While some students noted the AIGC avatar’s lack of naturalness, others appreciated the clear and professional speech it delivered.

The study was confined to seven students from a single course at one institution, which may limit the generalizability of the findings. Future research could involve a larger and more diverse group of participants.

The findings may offer education providers an alternative solution for engaging students in an LMS.

This study highlights the potential of AIGC avatars to replace text-based communication in LMS and enhance students’ perceived instructor social presence.

This study analyzes what type of influencer – microcelebrity or microinfluencer – is best suited to promoting healthy food brands and how that influence depends on consumers’ healthy lifestyles.

An empirical study with a real healthy food brand was developed in which three real influencers from Instagram collaborated and posted a story showing the company’s products. A total of 148 individuals participated in the study. The proposed model was tested using the PROCESS macro.

Drawing on the celebrity endorsement literature and the meaning transfer model, this study proposes that microcelebrities’ and microinfluencers’ influence on consumers’ perception and behavior in terms of post relevance, brand attitude and purchase intention toward healthy food brands depends on the consumers’ healthy lifestyle. Thus, microcelebrities have more influence on individuals with unhealthy lifestyles, while microinfluencers have more influence on individuals that pursue a healthy lifestyle.

It is one of the first studies to examine the different roles of microinfluencers versus microcelebrities in promoting consumers’ attitudes and behaviors toward healthy food brands. In addition, this is one of the few studies to show a higher effect of microcelebrities over microinfluencers.

Artificial intelligence (AI) has gained significant momentum in recent years. Among AI-infused systems, one prominent application is context-aware systems. Although the fusion of AI and context awareness has given birth to personalized and timely AI-powered context-aware systems, several challenges still remain. Given the “black box” nature of AI, the authors propose that human–AI collaboration is essential for AI-powered context-aware services to eliminate uncertainty and evolve. To this end, this study aims to advance a research agenda for facilitators and outcomes of human–AI collaboration in AI-powered context-aware services.

Synthesizing the extant literature on AI and context awareness, the authors advance a theoretical framework that not only differentiates among the three phases of AI-powered context-aware services (i.e. context acquisition, context interpretation and context application) but also outlines plausible research directions for each stage.

The authors delve into the role of human–AI collaboration and derive future research questions from two directions, namely, the effects of AI-powered context-aware services design on human–AI collaboration and the impact of human–AI collaboration.

This study contributes to the extant literature by identifying knowledge gaps in human–AI collaboration for AI-powered context-aware services and putting forth research directions accordingly. In turn, their proposed framework yields actionable guidance for AI-powered context-aware service designers and practitioners.

The purpose of this study is to explore brand customer erosion at both the category and brand levels while considering consumer socio-demographic characteristics and weight of purchase factors.

Data from 3,563 buyers encompassing 20,601 purchases were collected from a prominent household data panel.

Brand customer erosion varies depending on socio-demographic factors (householder age, family size, life cycle and social class) and weight of purchase; variations are evident depending on the specific brand.

The paper makes a substantial contribution to the established fields of marketing and consumer behavior literature by opening a new line of research. It does so by demonstrating, the impact of socio-demographic factors on customer erosion. Simultaneously, it presents results that contradict the limited existing research on the influence of weight of purchase on brand customer erosion.

This study aims to analyze the multicultural consumers’ perceptions multicultural consumers’ perceptions of their experience after participating in online cocreation actions in the fashion industry and the behavioral consequences of that experience.

This research was conducted in Spain and the UK, with 800 active online cocreators, leading to a proposal of a comprehensive model of the cocreation experience and its effects on satisfaction and engagement with the brand and the intention to continue cocreating using a multi-group covariance structural equation model.

All the proposed hypotheses were confirmed. Cocreation activities influence the cocreation experience, which, in turn, generates a positive effect on the behavioral responses of individuals in terms of satisfaction, engagement and future intentions to continue participating in the brand’s cocreation activities. The cocreation patterns are similar in both countries, leading to a comparable behavioral model across different cultural contexts. The findings conclude with relevant recommendations on how brands can improve their globalization strategies.

The practical utility for a fashion retailer arises from acknowledging the different dimensions of the cocreation experience as mechanisms to develop strategies that foster customer participation, thus enhancing satisfaction, brand engagement and advocacy. The results also advocate for the proposition of similar actions across different markets, given the homogeneity of behaviors, likely through global platforms that facilitate participation from different markets toward the creation of global communities.

The significant contribution of this research lies in the detailed proposal for measuring the cocreation experience and its integration into a comprehensive model of the impact of cocreation on classic behavioral variables. Furthermore, the differential analysis across two countries provides the added value of a multicultural evaluation of the phenomenon.

The paper aims to address the gap in the literature related to students’ mindsets and learning activities through investigation of the differences in students’ expectations of, feelings towards, and perceptions of an overseas study tour based on their mindset. The study provides an in-depth analysis of students with different mindsets and proposes the use of overseas tours and intercultural learning to foster students’ growth mindset.

An overseas study tour hosted by a self-financing tertiary institution in Hong Kong was selected for investigation. 13 sub-degree students participated in the study tour during the summer term in 2018. Two types of primary data – quantitative (i.e., a questionnaire survey) and qualitative (i.e., in-depth interviews) – of fixed mindset and growth mindset students were collected for analysis.

The findings indicate differences in students’ expectations of, feelings towards, and perceptions of an overseas study tour depending on whether they demonstrate a fixed or growth mindset. The growth mindset students had more and higher expectations of the study tour, all of which were related to personal growth and development. The fixed mindset students did not have as much of a desire for personal development and their expectations were easily met. Both growth and fixed mindset students had positive feelings and perceptions of the tour.

Research on the application value of overseas study tours in helping students from self-financing tertiary institutions develop a growth mindset is scarce, and thus warrants further investigation.
