Comparative Analysis of MCDM Methods for the Assessment of Corporate Sustainability Performance in Energy Sector Ersoy, Nazlı; Taslak, Soner Energy is a significant input for production, growth, and development. A sustainable energy sector, where energy production and consumption balance are ensured, constitutes a key point for nature and humanity. In this study, a multidimensional framework is presented to measure corporate sustainability in the energy sector. Based on this framework, the sustainability performance of energy companies operating in the Asia and Europe regions is measured by hybrid multiple-criteria decision-making (MCDM) methods, considering the economic, social and environmental dimensions of sustainability. The Entropy method is preferred to specify the criteria weights, the Proximity Indexed Value (PIV) -Range of Value (ROV) -Grey relational analysis (GRA) -Measurement Alternatives and Ranking according to Compromise Solution (MARCOS) methods are used to rank the alternatives. Sensitivity analysis was applied to test the robustness of the model and it was determined that the criterion weights obtained by different methods had different effects on the rankings. The Copeland method is used to obtain a single rational ranking from different rankings. According to Copeland's results, EN13, EN3, EN10 companies took the first place in economic, environmental and social dimensions, respectively. It is concluded that energy companies in the Asian region are more sustainable than in the European region. Moreover, Thailand is the most sustainable country in the Asian region. The proposed framework can be contributed to the development of the energy sector.

COVID-19 vaccination intent in university students and influencing factors: An analytical cross-sectional study Baybuga, Media Subaşı; Özkoç, Hatice; Akgün, Şenay Objective: To determine coronavirus disease-2019 vaccination intent and factors influencing the decision among university students. Method: The analytical cross-sectional study was conducted from 25 January - 25 February 2021 at a state university in Mugla, Turkey, and comprised undergraduate students. Data was collected using a self-designed questionnaire through Google Forms. Factors affecting vaccination intent were identified using multinomial logistic models. Data was analysed using SPSS 22. Results: Of the 1069 subjects, 629(58.8%) were females and 440(41.2%) were males. The overall mean age of the sample was 21.34±2.99. Overall, 712(66.6%) students were enrolled in health-related fields, and 357(33.4%) were pursuing non-medical degrees. Besides, 578(54.1%) students intended to have the vaccine. While 458(64.3%) of the subjects studying health-related subjects intended to have the vaccine, only 120(33.8%) in other academic streams said they would get vaccinated. Students who had had the disease or had been in contact with someone who had it 102(33%) were more likely to believe that the vaccine was safe. Smoking, having a flu vaccine in the past, and having a coronavirus disease-2019 test were the factors influencing the intent to have the vaccination (p<0.05). Conclusion: Having had a flu vaccine in the past, social media use, history of, or exposure to, coronavirus disease- 2019 and enrolment in health-related programme of studies were the factors influencing the vaccination intent of the students.
