  Influencer Authenticity in Marketing: A Systematic Literature Review and Future Research Agenda

  Celik, Fatih; Ibrahim, Blend; Polat, Eray; Moulard, Julie; Akbulut, Metin

  As influencer marketing scales into a mainstream advertising channel, authenticity has become its defining currency, yet consumers and brands struggle to understand what makes a social media influencer (SMI) genuinely credible and why strategic authenticity backfires. Despite growing scholarly interest, research remains fragmented, leaving practitioners without a unified framework to guide their decisions. Through a systematic literature review (SLR) of 138 peer-reviewed articles (2011-2024), using topic modeling and thematic analysis, we identify the authenticity paradox, the inherent conflict that arises when SMIs attempt to commercialize their genuine self-presentation. This tension also explains why recent evidence reports no overall engagement benefit from perceived authenticity. Seven latent topics are synthesized into four integrated axes: (1) ontological tensions at the technological interface, (2) the commercial transparency and trust paradox, (3) ethical negotiation in identity construction, and (4) strategic consumer responses. Our findings reveal how consumers continuously navigate between SMIs' curated performances and perceived genuineness, with self-determination theory, attribution theory, and parasocial interaction theory dominating current explanations, predominantly within USA-based contexts. Beyond mapping the field, we specify three conceptual patterns, namely authenticity as attributed intent, transparency as coherence rather than concealment, and authenticity as a structurally constrained accomplishment. We then translate the gaps they expose into a structured research agenda, offering actionable insights for brands, managers, and platform designers on authenticity management, influencer selection, partnership governance, and performance evaluation.

  A reliability generalization meta-analysis of job insecurity scales: Evidence from hospitality and tourism research

  Polat, Eray

  The study examines the pooled reliability estimates of job insecurity (JI) scales employed in hospitality and tourism (H&T) research. By synthesizing reported reliability coefficients and identifying moderators influencing score consistency, this meta-analytic study consolidates the fragmented psychometric evidence in the field. Reliability coefficients were derived from 140 independent samples comprising 56,265 respondents. Pooled reliability estimates were calculated separately for each scale, and moderator analyses were performed to explain the variability. Findings indicate that De Witte's (2000) scale is the most frequently utilized scale. Pienaar et al.’s (2013) scale yielded the highest estimate (α=.94, 95% CI [.89.,97]), whereas Hellgren and Sverke's (2003) scale demonstrated the lowest (α=.82, 95% CI [.78.,85]). Moderator analyses revealed that scale version, publication year, number of items, sample size, scale mean, and gender distribution significantly influenced reliability estimates. The study provides robust, context-dependent evidence to inform the selection of JI scales.

  Predictors of citations: an analysis of highly-cited-papers in hospitality and tourism research using a machine learning approach

  Polat, Eray; Çelik, Fatih; Arici, Hasan Evrim; Köseoglu, Mehmet Ali

  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 past scene of hospitality ethics: A citation analysis perspective

  Polat, Eray; Köseoglu, Mehmet Ali

  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.

  The effect of perceived overqualification on relative deprivation: The moderating role of organisational silence

  Polat, Eray; Esen, Ozan; Çalışkan, Serkan

  This study aimed to adapt the Mature Happiness Scale-Revised, developed based on the Positive Psychology 2.0 (PP 2.0) theoretical framework, into Turkish. The study tested the linguistic equivalence, structural validity, and internal reliability of the scale. Validity and reliability were analysed using data collected from 303 white-collar employees working in various sectors in Istanbul. For linguistic equivalence, item-level correlations between the English and Turkish forms ranged from moderate to high (0.504–0.768), and the total score correlation was extremely high (r = 0.990). Confirmatory factor analysis (CFA) supported the single-factor model of the scale with good fit indices (CFI = 0.972; GFI = 0.974; AGFI = 0.944; RMSEA = 0.064). The scale's internal consistency was "good," with a Cronbach's Alpha coefficient of 0.797. Therefore, the Turkish version of the Mature Happiness Scale was determined to be a theoretically and psychometrically valid and reliable measurement tool. This scale can serve as a valuable tool for supporting research in positive psychology and understanding individuals' psychological well-being within the Turkish cultural context.

  Mapping Ethics Research in the Hospitality Scholarship

  Polat, Eray; Köseoglu, Mehmet Ali

  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.

  Authentic Leadership: A Systematic Review and Research Agenda

  Polat, Eray; Arici, Hasan Evrim; Arasli, Huseyin

  There has been a growing interest in authentic leadership as a distinctive style of leadership and a dynamic research topic. In this direction, the aim of this study is multifaceted. First, we focus on providing a comprehensive overview of research on authentic leadership (AL), which has attracted substantial research interest in the last few years. Second, we outline the theoretical and nomological network of AL, highlighting antecedents, outcomes, moderators, and mediators. Third, we offer an elaborated future research agenda to enable advances in theory and empirics. We systematically reviewed 182 articles issued in the business management and psychology literature between 2005 and 2021. Interest in AL is growing, and 2020 is the golden year. Developed countries dominate the field. After a rigorous review, we offer a future research agenda with four key themes. The study highlights that AL is critical to the emergence and growth of valuable behaviours, attitudes, and performance at individual, team, and organisational levels. The study provides new research ideas and further conceptualization of AL. We also provide a comprehensive review of why managers should continue to practice AL, where the literature has been, and where it may be headed in the future.

  Publishing in Hospitality and Tourism Journals: Revisiting the Criteria Used by Leading Reviewers in Turkey

  Polat, Eray

  This study aims to identify the criteria reviewers use to determine whether to accept or reject empirical manuscripts and to define which criteria are more significant. In this exploratory study, which utilizes qualitative research methods, 16 members of the Scientific Committee of the National Tourism Congress of Turkey were asked to identify the primary areas they focus on when reviewing a manuscript. The data was analyzed using content analysis to determine the most significant criteria. The study identifies six criteria for acceptance and seven for rejection. The most important criterion for acceptance is the appropriateness and adequacy of the research method, while the most crucial criterion for rejection is methodological weakness. Other criteria influencing the reviewers' acceptance or rejection decisions focus on similar issues. The critical factor that distinguishes them is how the manuscript meets the requirements established by the reviewers. The study provided recommendations for future researchers.

  Reliability generalization meta-analysis of the food neophobia scale: Turkish sample

  Polat, Eray; Çalişkan, Serkan

  Purpose: The Food Neophobia Scale developed by Pliner and Hobden (1992) has been widely utilized globally and in Turkey for many years to measure people's fear of new foods. This study aims to determine the mean value by conducting a reliability generalization meta-analysis for the reported reliability coefficients of individual studies in Turkey's tourism field, which employed Pliner and Hobden's scale to investigate food neophobia. Additionally, this study explores variations in the mean value among subgroups. Methods: A reliability generalization meta-analysis based on a random-effects model was conducted to examine the heterogeneity of reliability coefficients in the study, along with heterogeneity analyses and moderator analyses. Results: Based on the analysis of 48 independent samples (N= 23306), the transformed mean Cronbach's alpha value was estimated to be .827 (95% CI [.796-.853]) and found to be significant. The Q-test and I2 values reveal significant heterogeneity between alpha coefficients, indicating a notable variation in the measurement reliability across samples. Moderator analyses using analog to the ANOVA and meta-regression analyses showed that reliability coefficients differed according to the variables of publication type, sample type, and proportion of women in the sample. Implications: The results offer valuable insight for researchers seeking to select appropriate scales for investigating food neophobia.
