Cultural heritage tourism is a very important issue for the cultural transfer and sustainability of tourism. In parallel, cultural heritage tourism in the context of sustainability has become a popular field that has attracted the attention of researchers in recent years. Therefore, this study aims to analyze international publications on the relationship between cultural heritage tourism and sustainability, identifying trends in development and future research opportunities. Based on this purpose, 657 related studies have been found in the Web of Science database and analyzed in the Bibliometrix R package to map and systematically review the literature. By focusing specifically on the relationship between cultural heritage and sustainability, this study fills a gap in the existing literature, which often handles these issues separately. In addition, the research results contain valuable information that can shape future research agendas.

Ethnocentric attitudes and beliefs are defined as prejudice against those who do not belong to one’s own community and are based on the understanding of considering one’s own nation to be superior. When the concept is interpreted from a tourism perspective, the conformity of the experiences with the norms of society can be described as the ensemble of attitudes and behaviors aimed at glorifying future domestic tourism welfare. When the destination experiences are evaluated, food constitutes the largest experience area within the tourism market. Besides transferring recipes and flavor elements to individuals, food also conveys the culture, beliefs, and value judgments of a society to future generations. Based on this point, the relationships between tourism ethnocentrism, destination advocacy, local food motivation, and destination food image were investigated in this study. In the scope of the study, a survey was conducted on people who visited the Gaziantep region and had a dining experience. Structural equation modeling was utilized in line with the study model. According to the findings of the study, local food motivation has a positive and significant effect on destination food image and tourism ethnocentrism, and tourism ethnocentrism positively and significantly affects destination food image and destination advocacy. Moreover, destination food image has a positive and significant effect on destination advocacy.

Safety culture is a key feature between employees’ job performance and organizational commitment. Hotel businesses are an important component of the service sector, and a customer-oriented approach in these businesses increases organizational performance. Therefore, the increased organizational commitment of employees plays an important role in the implementation of a customer-oriented approach. In this study, hotel safety culture, which is one of the important factors for business performance sustainability, is examined. In addition, the effect of hotel safety culture on job satisfaction, organizational commitment and customer-oriented behavior is examined. In this context, the research data were collected from the employees of 5-star hotels operating in Antalya and Doha through a questionnaire. The data were analyzed using PLS-SEM 4.0. As a result of the research, some significant effects were found between the variables in the hypothetical research model. Based on the results obtained, theoretically, in support of the studies in the literature, a positive relationship was found between perceived safety culture and employees’ job performance. Accordingly, as practical suggestions, it is recommended that hotel managers take measures to increase the safety culture (staff training, increasing physical measures, making warning signs visible, etc.).
