Promoting transition towards sustainable air transport systems: A hybrid decision support system for effective national-level performance evaluation
(ELSEVIER SCI LTD, 2025) Kara, Karahan; Yalçın, Galip Cihan; Özekenci, Emre Kadir; Bilek, Günal; Simic, Vladimir; Tunçsiper, Çağatay; Pamucar, Dragan
Air transport plays a pivotal role in enhancing economic development by supporting trade, tourism, and regional competitiveness. The growing environmental concerns and social expectations have necessitated the transition towards sustainable air transport systems. Sustainable air transport refers to aviation activities that balance environmental, economic, and social objectives, aiming to minimize carbon emissions, promote renewable energy usage, and enhance socio-economic welfare. In this study, a novel multi-criteria decision-making (MCDM)based decision support system (DSS) is proposed to evaluate the sustainable air transport performance of the European countries. The main objective of this research is to develop a comprehensive and integrative framework for measuring and ranking the sustainable air transport performance of nations. A hybrid method, termed fractional fuzzy-ranking comparison-response to criteria weighting (RANCOM)-response to criteria weighting (RECA)-ranking technique by geometric mean of similarity ratio to optimal solution (RATGOS), is introduced. DSS consists of five main stages: expert-based subjective weighting using fractional fuzzy RANCOM, objective weighting via RECA, aggregation of weights, and final performance ranking through the RATGOS method. The results indicate that Germany ranks highest, while Cyprus has the lowest sustainable air transport performance among the evaluated countries. The criterion "commercial aircraft fleet by age of aircraft" is determined to have the highest importance among the sustainable air transport performance indicators. The study provides a comprehensive, replicable framework for policymakers and stakeholders aiming to monitor and improve sustainable aviation systems. It contributes to the literature by addressing the gap in national-level sustainable air transport performance evaluation.

Performance Measurement of the Logistics Companies on the Fortune 500 by Swara and Merec-Based Cradis Methods
(SCIENDO, 2024) Ozekenci, Emre Kadir
The aim of this study is to evaluate the performance of logistics companies on the Fortune 500 Turkey list using the SWARA-MEREC based CRADIS methods. The weight of criteria was determined by subjective and objective approaches, namely SWARA and MEREC, respectively. The performance of companies was ranked by the CRADIS method. The findings highlighted that net sales (NS) and export (EXP) were most and least important criteria, respectively. The result of the CRADIS method showed that Netlog, Borusan and Ekol had the highest performance, while Noatum, BDP International and Horoz had the lowest performance in 2022, respectively. The reliability and robustness of the proposed model was tested with sensitivity and comparative analyses. The results of the sensitivity analysis and comparative analysis showed that the proposed model provides consistent results.

The Mediating Role of Forgiveness and The Moderating Role of Perceived Partner Responsiveness in The Relationship Between Victim Sensitivity and Subjective Well-Being in Romantic Relationships
(ÇUKUROVA ÜNİVERSİTESİ, 2025) Doğruyol, Sena; Aslan, Aslı
Understanding how the concept of victim sensitivity in romantic relationships is perceived by married adults and evaluating this concept within the framework of subjective well-being is of great importance. The primary aim of the current research is to assess an individual's subjective well-being in the context of victim sensitivity, perceived partner responsiveness, and forgiveness variables. In this direction, the mediating roles of forgiveness (avoidance, retaliation, and benevolence) in the relationship between victim sensitivity and subjective well-being have been tested first. Subsequently, the moderating role of perceived partner sensitivity in the relationship between victim sensitivity and forgiveness was examined. The study group consists of a total of 398 participants, including 230 women and 168 men. Data were obtained using Satisfaction with Life Scale (SWLS), Positive-Negative Affect Scale (PANAS), Marital Forgiveness Scale-Event (MFS-E), Perceived Partner Responsiveness Scale (PPRS) and Victim Sensitivity in Romantic Relationships Scale (VSRRS). Furthermore, a demographic information form prepared by the researcher was used to collect personal information such as gender, age, monthly income, duration of marriage, and education level. Before analyzing the data, assumptions such as sample size, outliers, missing values, linearity, normality, and multicollinearity were also tested. The results indicated that avoidance and benevolence serve as mediating roles in the relationship between victim sensitivity and subjective well-being, while retaliation does not have a significant role. Furthermore, when analyzing the results of the moderating variable, it suggests that perceived partner responsiveness does not have a moderating role in the relationship between victim sensitivity and forgiveness. In conclusion, high levels of victim sensitivity in romantic partners may lead to negative experiences within the relationship. Therefore, the development of intervention programs targeting this domain may offer valuable guidance for future research and therapeutic practices.

Teacher Cognition and Practices in Using Generative AI Tools to Support Student Engagement in EFL Higher-Education Contexts
(MDPI, 2025) Zaimoğlu, Senem; Dağtaş, Aysun
As Generative Artificial Intelligence (GenAI) tools become increasingly embedded in higher education, English as a Foreign Language (EFL) teachers are challenged to rethink their pedagogical identities and practices. While policy discourses often promote GenAI for its potential to enhance instructional efficiency, little is known about how language teachers conceptualize and employ these tools to foster meaningful student engagement. This study explores how university-level EFL teacherinterpret and implement GenAI technologies to support student engagement through narrative inquiry. Drawing on three-level narrative approach, story, Story, and STORY, it examines nine language teachers' retrospective experiences with GenAI tools across personal, contextual, and sociopolitical dimensions. The findings indicate that teachers' interactions with GenAI are shaped by their pedagogical affordance, as well as their teaching values, imposed political agendas, and professional agency. This study calls for professional development programs specifically designed for teachers' narrative identities to ultimately facilitate the ethical use of GenAI in learner-centered EFL contexts.

Body Image And Body Dissatisfaction In Early Childhood
(ÇUKUROVA ÜNİVERSİTESİ, 2024) Kale, Mustafa; Gül, Ebru Deretarla; Kaya, Muhammet Talha; Çakmak, Soner
In this study, the relationship between body image scores perceived and desired by children in early childhood and body dissatisfaction was investigated. The relational survey method, one of the quantitative research methods, was used in the study. A total of 539 children (268 boys and 271 girls) between the ages of 4 and 6 attending seven state kindergartens in Adana were included in the study. The pictogram scale for children developed by Colllins (1991) was used to determine body image. In addition, anthropometric measurements were made to calculate the body mass index of the children. Data were analyzed according to the distribution of BMI z-scores of boys and girls according to current body shape. Given that the data were not normal, the Spearman correlation coefficient was used to confirm the correlation between the BMI z-score and the current body size and degree of body dissatisfaction in both sexes. The SPSS 26 statistical package program was used in the analysis of the data. While girls want a slimmer body from their children, boys, on the contrary, want a larger body. It shows that about 34% of children have body dissatisfaction.
