The tourism and hospitality sector is known for its excessive consumption of natural resources, waste generation, and negative environmental impacts. The concept of circular economy (CE) has gained increasing attention in recent years as a strategy to promote sustainability and resource efficiency in various industries, including tourism and hospitality. This bibliometric analysis aims to provide a comprehensive overview of current research trends regarding the adoption of CE principles in the tourism and hospitality sector. Unlike conventional methods, a comprehensive bibliometric analysis combined studies from Web of Science and Scopus databases between 2013 and 2024 using the keywords circular economy, tourism, and hospitality. In this research, which includes 314 articles selected in accordance with the PRISMA protocol, it is seen that CE applications are becoming increasingly important. The research results show that there has been a significant increase in the number of publications since 2015; the most productive countries are Italy, Spain, and China, and topics such as waste management and recycling stand out as motor themes. It is thought that the number of studies on practical applications and niche themes should increase and future research suggestions are presented.

The increase in the world’s population is driving consumption, leading to the rapid destruction of natural resources and thus raising concerns about the future state of resources. Agriculture and livestock activities, which can be considered under the heading of food, are one of the most significant factors having effects on sustainability. Animal welfare and ethical food selection have become important issues along with sustainability as people’s awareness has increased. As restaurants are an important part of the food industry, chefs have the power to influence sustainability and ethical food choices and set trends with the choices they make. In this respect, it is important to predict the sustainable and ethical food preferences of gastronomy and culinary arts (GCA) undergraduate program students who have the potential to become the chefs of the future, and to evaluate to what extent they regard chefs as responsible for these issues. In this study, the data obtained from GCA undergraduate students were analysed with the decision tree method using lavaan and rpart packages in the R program. The main objectives of this research are to determine the importance of the independent variables in the decision tree classification and the effects of these independent variables. The analysis suggests that the most important factor in the decision tree classification of the independent variables is the attitude towards sustainable food choice. It is concluded that the independent variables are effective in classifying students as high and low in terms of behavioural intention. It is also seen that attitude towards sustainable food choice is more effective in predicting whether behavioural intention is high or low.

Örgütlerin içinde bulundukları kriz sürecinde sosyal medya üzerinden paydaşları ile ilişkilerini çok hızlı ve aynı zamanda örgütün meşruluğunu destekleyen güvenilir mesajlar ile sürdürmeleri örgütün kurumsal itibarını zedeleyebilecek hasarlardan kaçınmak, paydaşların güvenini korumak ve örgüte ilişkin olumlu davranışsal niyetlerini devam ettirmeleri adına önemlidir. Bu doğrultuda bu mesajların yaratılması için kriz döneminde örgütün söylediği ve yaptığı olarak tanımlanan krize yanıt stratejilerinin içeriği ve etkisinin araştırılması gerekmektedir. Bu nedenle bu çalışma krize yanıt stratejilerinden özür, acıyı paylaşma/anlayış ve bilgilendirici stratejiler arasında algılanan kurumsal itibar, güven ve davranışsal niyet açısından bir farklılık yaratıp yaratmadığını incelemeyi amaçlamaktadır. Alan araştırması ile 2016 yılı Ekim ayında uygunluk örneklemi ile Antalya’daki 1080 Facebook kullanıcısı öğrenci araştırmaya dahil edilmiştir. Araştırmanın sonucunda, krize yanıt stratejilerinin kurumsal itibar, güven ve davranışsal niyet üzerindeki etkisi incelendiğinde fark yaratan stratejinin acıyı paylaşma /anlayış stratejisi olduğu tespit edilmiştir.

Corporate reputation is of growing interest in communication studies as an intangible and inimitable asset. The multiple-stakeholder view of reputation is believed to intersect with the responsibility of the field of public relations. This study explores the intellectual landscape of corporate reputation research within public relations by identifying current trends such as the influence of social media and crisis communication on stakeholder relationships. These trends are crucial for understanding how public relations strategies adapt to evolving communication platforms and global crises, directly affecting corporate reputation by shaping public perception and trust. The study systematically examines 10,873 academic publications retrieved from the WoS database using bibliometric analysis. The analysis employs BiblioShiny and VOSViewer due to their advanced capabilities in visualising performance metrics and mapping scientific networks. The findings suggested that social media, crisis communication, and COVID-19 hold significance and are fundamental to the field of public relations in terms of corporate reputation. Keyword co-occurrence network analysis suggested that public relations, corporate reputation, and crisis communication are three clusters that reflect the crucial role of public relations in both cultivating and sustaining corporate reputation, as well as its significance in managing crisis communication effectively. These findings emphasise the necessity for organisations to adopt proactive crisis communication strategies and integrate social media into reputation management. Integrating these topics into public relations curricula can better prepare future professionals to manage corporate reputation in a complex media landscape.

Bu çalışma Türkiye’deki kamuları, kamuların durumsal kuramı ile segmente ederek aktif, uyanmış ve gizli kamuların profil özelliklerini ortaya çıkarmayı amaçlamaktadır. Bu doğrultuda İstanbul, Ankara ve İzmir illerinde kamuların durumsal kuramının değişkenleri ve demografik sorulardan oluşan 443 anket formu ile ampirik bir alan araştırması gerçekleştirilmiştir. Araştırma sonucunda kamular kurama göre aktif, uyanmış ve gizli kamu olarak segmente edilmiş ve en kalabalık kamu segmenti uyanmış kamu olarak tespit edilmiştir. Ancak aktif kamunun da sayısal olarak güçlü tespit edilmesi bugüne kadar genellikle asimetrik olarak inşa edilen ilişkileri sorgulatmaya başlayacağını düşündürmektedir. Bu sorgulamanın Türkiye’de halka ilişkiler alanında var olan karmaşanın bütünlüğe kavuşması açısından üç boyutlu olarak; örgütler, uygulayıcılar ve akademi tarafından gerçekleştirilmesi önerilmektedir. Bu çalışma aktif kamunun varlığı açısından yorumlandığında örgütler, uygulayıcılar ve akademiyi içeren halkla ilişkiler alanının üç sacayağı için bir takım sonuçlar yaratmaktadır.

The effectiveness of government policies and environmental initiatives to mitigate global warming relies heavily on public support, which is closely tied to public perception and awareness. Despite the scientific evidence communicated, the public remains reluctant to take preventive measures against global warming. The aim of the paper is to investigate the communicative actions of publics proposed as in the situational theory of problem solving to understand publics' communicative actions towards global warming. The paper utilizes a fuzzy rule-based system approach to analyze the communicative actions of publics to reveal non-linear relationships; whereas previous studies mostly used linear statistical analysis. The paper provides a deeper understanding into the interplay between problem recognition, constraint recognition, and involvement in shaping information behavior. The results show that the communicative actions of the publics are at a low-to-moderate level. The paper's interesting finding is the nonlinear effects of constraint recognition on communicative action about global warming. Contrary to the current literature, it was found out that the dominant factor that may convince public to start taking action towards global warming seems to be recognizing being constrained at a moderate level. Based on the results, it is suggested for policy makers and communication strategists to mitigate the negative outcomes of global warming by integrating environmental issues into education at all levels and collaborating with non-governmental organizations for national awareness campaigns which focus on increasing public problem recognition and involvement.
