Notwithstanding their potential benefits especially for individuals with low health literacy, users are still somewhat skeptical about the reliability of healthcare chatbots. The present study aims to address this challenge by investigating strategies to enhance users’ cognitive and emotional trust in healthcare chatbots. Particularly, this study aims to understand the effects of chatbot design cues in increasing trust and future chatbot use intention for low health literacy users.

We conducted two experimental studies with a final sample of 327 (Study 1) and 241 (Study 2). Three different chatbots were developed (Chatbot design: Bot vs Male-doctor vs Female-doctor). Participants were asked to have a medical consultation with the chatbot. Participants self-reported their health literacy scores. The PROCESS model 7 was used to analyze the hypotheses.

The results showed that the female-doctor cues elicited greater cognitive and emotional trust, whereas the male-doctor cues only led to greater cognitive trust (vs bot-like cues). Importantly, this study found that users’ health literacy is a significant moderating factor in shaping cognitive and emotional trust. The results indicated that both the female and male-doctor cues’ positive effects on cognitive trust were significant for those with lower levels of health literacy. Furthermore, the positive effect of the female-doctor cues on emotional trust was also significant only for those whose health literacy level was low. The increased cognitive and emotional trust led to greater future intention to use the chatbot, confirming significant moderated mediation effects.

Despite the strong economic and educational benefits of healthcare chatbots for low health literacy users, studies examining how healthcare chatbot design cues affect low health literate users surprisingly remained scarce. The results of this study suggest that healthcare chatbots can be a promising technological intervention to narrow the health literacy gap when aligned with appropriate design cues.

“Contactless service” refers to the use of technology in providing products or services without a salesperson. This study explores the mechanism underlying Millennial and Generation Z (M/Z generations) consumers' preference for contactless service over salespersons in retail stores. In addition, this study tests differences between the M/Z generations.

The researchers predict characteristics to be antecedents of young consumer's preference for contactless service over salespersons and that the effects are mediated by technology self-efficacy. Next, a moderating variable (perceived consumer conformity) is added in the path between technology self-efficacy and the preference for contactless service. The hypotheses are tested among 142 Gen Z and 137 Millennial respondents.

The results show that M/Z generations’ characteristics significantly influence the preference for contactless service, except for security seeking. Also, interests in new technology and safety seeking are perceived higher by M/Z generations. The influence of technology self-efficacy on the preference for contactless service is moderated by social conformity.

As retail technology rapidly develops, the service industry is expected to change from the past, where salespersons played an important role, to contactless services. This study has academic and practical values, for the authors clarify the underlying psychological mechanisms of why young consumers prefer retail technology rather than communication with salespersons.

The purpose of this study was first to examine how goal-oriented attendees and experiential-oriented attendees were related with their overall satisfaction and loyalty of the destination with respect to international food and wine festival. It also investigated how these relations are mediated by different dimension of experiential consumption values such as consumer return on investment (CROI, active value), escapism (active value) and service excellence (reactive value) and aesthetics (reactive value).

Self-administered questionnaires were distributed to and collected from attendees at the 2011 Food Network South Beach Wine and Food Festival in Miami, Florida. A total of 450 subjects were collected from attendees indicating a response rate of about 88 per cent. Total 13 hypotheses were tested using structural equation model (SEM) with AMOS, and the results were interpreted adapting Mathwick’s (2001) typology of experiential value.

The findings indicate that goal-oriented attendees had stronger relationship with reactive experiential values such as service excellence and aesthetics than active values, whereas experiential-oriented attendees had more significant relations with active experiential values such as CROI and escapism than reactive values. In addition, CROI, escapism and service excellence were found to have a positive influence on the overall satisfaction with the festival; in turn, the attendees’ satisfaction had a positive effect on their intention to revisit the destination. Further, the results demonstrated that all experiential values, including CROI and escapism (active values), and service excellence and aesthetics (reactive values), played a mediating role between goal-oriented/experientially oriented attendee and satisfaction with the festival.

The festival organizers and managers should understand what drives the attendees’ participation in the festival. Implementing experiential marketing through various dimensions of experiential value can attract more potential attendees, provide unique experiences and create favorable perception toward the destination.

The research is original in terms of conceptualizing and empirically testing the relation between experiential consumption values and behavior loyalty within the special events and festivals with a specific focus on international food and wine festival. A finding of particular importance here is verifying the unique characteristics of goal-/experiential-oriented attendees in festival settings and determining the linkages between these different attendees and active/reactive experiential values, not to mention the relation with the overall satisfaction and loyalty to the festival destination.

This paper aims to propose an operation policy of multi-capacity room service robots traveling within a hotel. As multi-capacity robots can serve many requests in a single trip, improved operation policy can reduce the investment cost of robots.

Using a mathematical model-based optimization technique, an optimal set of robots with minimum installation cost is derived while serving the entire room service demands. Through testing a variety of scenarios by changing the price and function of robots to be installed, insights that consider the various situations are offered.

Though the increase in capacity saves much time for room service at a lower capacity level, the amount of time saved gradually decreases as the capacity increases. Besides, the installation strategy is divided into two cases depending on the purchase cost of robots.

Currently, the studies focusing on the adoption of service robots from an operations view are rarely be found. To reduce the burden of investment cost, this study takes the unique approach to improve the operation policy of service robots by using the multi-capacity robots.

This study guides the hotel to install an adequate set of robots. The result confirms that the optimal installation set of robots is affected by various factors, such as the room service information, the hotel structure and the unit execution cycle.

After the outbreak of COVID-19, people avoid face-to-face contact and interest in non-contact service is growing. This paper deals with the efficient way to implement non-contact delivery through logistic robots, a timely and important topic.

Drug repurposing involves the identification of new applications for existing drugs. Owing to the enormous rise in the costs of pharmaceutical R&D, several pharmaceutical companies are leveraging repurposing strategies. Parkinson's disease is the second most common neurodegenerative disorder worldwide, affecting approximately 1–2 percent of the human population older than 65 years. This study proposes a literature-based drug repurposing strategy in Parkinson's disease.

The literature-based drug repurposing strategy proposed herein combined natural language processing, network science and machine learning methods for analyzing unstructured text data and producing actional knowledge for drug repurposing. The approach comprised multiple computational components, including the extraction of biomedical entities and their relationships, knowledge graph construction, knowledge representation learning and machine learning-based prediction.

The proposed strategy was used to mine information pertaining to the mechanisms of disease treatment from known treatment relationships and predict drugs for repurposing against Parkinson's disease. The F1 score of the best-performing method was 0.97, indicating the effectiveness of the proposed approach. The study also presents experimental results obtained by combining the different components of the strategy.

The drug repurposing strategy proposed herein for Parkinson's disease is distinct from those existing in the literature in that the drug repurposing pipeline includes components of natural language processing, knowledge representation and machine learning for analyzing the scientific literature. The results of the study provide important and valuable information to researchers studying different aspects of Parkinson's disease.

This paper intends to discuss the effect of social and institutional mechanisms in allowing network governance embedded in non‐contractual and social relations to emerge and persist.

Building on the extant theoretical literature on network governance of varied research strands and drawing empirical observations from research on East Asian network governance, the paper explores the effect of social and institutional mechanisms in allowing network governance embedded in non‐contractual and social relations to emerge and persist.

It is argued that social and non‐contractual mechanisms reinforce, substitute, or undermine contractual mechanisms, but the degree to which this occurs is contingent on institutional environments in which transaction occurs.

The paper revisits some of the important theoretical concepts such as trust and social capital that have been invoked across divergent literatures so as to illuminate underlying factors of economic governance based on social relations and networks.

The purpose of this study is three fold: to provide a preliminary exploration of meeting planners' use and perceived usefulness of the different types of social media; to examine why meeting planners use social media and; to investigate the perception of adopting the social media, especially as perceived critical mass impacts the adoption of social networking media.

Data were collected from the members of a professional association for meeting professionals in the Southwest US using an online self‐administered questionnaire. A total of 510 members received an invitation to take the survey and 120 responses were received, representing a 23.5 percent response rate. Descriptive analysis, discriminant validity, reliability and path analysis were used to estimate the relationships between the five constructs: perceived critical mass, usefulness, ease of use, attitudes and intention to use social network media in the future.

The most commonly preferred social network sites were Facebook (29 percent), LinkedIn (15 percent), YouTube (13 percent), Twitters (11 percent) and My Space (11 percent) and the social networking media rated most useful were Facebook (mean=3.7), LinkedIn (mean=3.1), YouTube (mean=3.0), Blogs (mean=2.7), Webinars (mean=2.6) and Twitter (mean=2.5), The top three reasons for using social media were: to communicate with other planners easily and quickly through chat or discussion boards (80.4 percent), to share queries, problems, solutions and opinions with other meeting planners (70.1 percent) and to get feedback from attendees after meeting/event/convention (69.9 percent). Additionally, the path model used in the analysis indicated that perceived critical mass not only directly influences intention to use social network media but also indirectly affects attitude toward using social media and intention to use social media simultaneously through perceived ease of use and perceived usefulness.

Even though the social networking media has previously been used by many meeting planners to find information, few research studies have explored the meeting planners' perception of social networking media and what factors may have an effect on meeting planners' adoption of using social network media. This study provides a preliminary empirical analysis of meeting planners' perception of these tools and the factors that influence their utilization.

This primer defines and describes conscious and nonconscious perception and assessment processes by tourists. The primer links the field of tourism perception studies to the literature of experimental social psychology. The primer describes the important roles that metaphors play in connecting conscious and nonconscious thinking and how both tourism brand managers and tourists use metaphors to use stories to enable enactments and favorable outcomes of archetypal motivations. The primer introduces formal implementable models of the major tenet in Urry’s tourist gaze – visitors’ home culture automatically and mostly nonconsciously profoundly influences their perceptions, assessments, and interpretations of what they see when traveling and visiting away destinations. Model implementation includes applying Boolean algebra-based asymmetric tests instead of symmetric matrix algebra-based statistical tests – the asymmetric tests examine for the consistency of high scores in perceiving, assessing, and behaviors of complex configurations of antecedent conditions. A detailed empirical example of asymmetric testing includes consistent high scores for Americans, Brits, Canadians, and Germans for not shopping for gifts to take home during their visits to Australia. This primer also introduces the concept of the tourist meta-gaze – seeing and assessing outside the automatically activated culturally based tourist gaze.
