In the dynamic nature of hospitality and tourism (H&T) research, it is increasingly difficult to distinguish highly-cited-papers (HCPs) due to the rapid proliferation of publications. This study employs machine learning techniques to identify the predictors of citation counts in H&T research over both short-term (5-year) and long-term (20-year) periods using HCPs. The analysis integrates a theoretical framework comprising normative theory and social constructivist theory. The findings indicate that international citation, PlumXmetrics, and early citations are the most effective determinants in both periods. Furthermore, while the importance of international citations is evident in both periods, the order of importance of the other two predictors changes. PlumXmetrics are more important in the long-term, while early citations are more important in the short-term. In conclusion, this comprehensive and up-to-date study of citation dynamics provides valuable insights for scholars and other stakeholders interested in enhancing the visibility and influence of H&T literature.

The literature on ethics research in hospitality has significantly expanded in recent years. The objective of this study is to present a comprehensive overview of ethical research in the field of hospitality literature. This will facilitate insight into future developments by examining the past. A two-step approach is employed, comprising citation analysis, a bibliometric analysis technique, and a systematic review. The former is used to identify themes, which are then discussed in the latter. The citation analysis revealed five main themes of the domain: environmental concerns, organisational citizenship behaviour, reputation management and ethical leadership. Environmental concerns were examined from two perspectives: the viewpoint of hotels and the environmental behaviours of tourists and consumers. Subsequently, a systematic review was conducted using the TCM framework (theory/context/methodology) with the objective of identifying the most prominent theories, contexts, and methodological issues associated with each theme. The issue has predominantly been discussed using quantitative analysis and social-based theories. Research has been mainly conducted in the US and the EU. Environmental ethics is likely to remain a significant area of concern in the future. This study offers a perspective that can aid researchers in developing future studies on ethics and help practitioners enhance the ethical climate of the industry.

This paper examines the role of ethics-related research in shaping the intellectual structure of hospitality-literature through a two-step method. The intellectual structure of the most-cited ethics-related references was revealed by co-citation analysis. Content analysis was made to reveal each cluster’s main themes. A database comprising 9664 references from seven hospitality journals, spanning 60 years, was analyzed. The analysis uncovered four thematic clusters, indicating that organizational citizenship behaviors and environmental-ethics are the predominant topics in the hospitality-ethics literature. The previous studies heavily focused on examining relationships and their practical implications. The study adopted a novel approach to bibliometric analysis that has never been used in hospitality ethics-reviews. The results of the concept-discipline-focused hybrid-review provide a comprehensive understanding of the knowledge domain and indicate research directions.

We review user-generated video (UGV)-research in hospitality and tourism (H&T), provide an overview of its current-state, and suggest ways forward. We adopted a systematic literature review methodology and reviewed 66 articles with TCM (theory/context/methodology) framework. UGV-research focuses on (i) destination image perception, (ii) short-form videos and travel live-streaming, (iii) behavioral intentions, and (iv) crisis management. Theoretical development is diverse, given the descriptive nature of research questions, but it is still in its infancy. The context varies by H&T setting, type of social media platform, population, and country. Research methods and techniques range from traditional analysis to advanced machine learning or artificial intelligence-based quantitative approaches, predominantly qualitative methods.
