Yayın Optimizing sustainable industry investment selection: A golden cut-enhanced quantum spherical fuzzy decision-making approach(Elsevier, 2023) Dinçer, Hasan; Yüksel, Serhat; Sonko, Mariama; Hacıoğlu, Ümit; Yılmaz, Mustafa Kemal; Delen, Dursun; Yönetim Bilimleri Fakültesi, İşletme BölümüThis study aims to rank sustainable industry alternatives in emerging markets based on the directional impact relations of the environmental, social, and governance (ESG) index components for a socially and environmentally conscious investment strategy. To achieve this goal, we employ a golden cut-enhanced quantum spherical fuzzy decision-making approach. Specifically, we first use a quantum spherical fuzzy DEMATEL technique to identify the impact-relation directions and the weights of the ESG criteria set. Second, we employ the extended TOPSIS with the quantum spherical fuzzy sets to rank the industry alternatives concerning their directional ESG performances. The findings show that (i) H20 Emissions, Innovation, Community Investment, Gender Equity, Human Rights, and CSR Strategy are the main influencing factors based on their impact-relations directional scores, (ii) Resource Usage, Product Responsibility, and Shareholders’ Rights are the set of criteria under the influence of remaining ESG, (iii) Innovation is the strongest ESG performance criterion, whereas Human Rights is the weakest, (iv) technology and communication are the best-performing industries based on the directional ESG index performance scores, whereas real estate and basic materials industries are the worst performing. The study provides valuable and actionable insights for companies that aim to make socially responsible investments.Yayın Crafting performance-based cryptocurrency mining strategies using a hybrid analytics approach(Elsevier, 2021) Chlyeh, Dounia; Hacıoğlu, Ümit; Tatoğlu, Ekrem; Yılmaz, Mustafa Kemal; Delen, Dursun; Yönetim Bilimleri Fakültesi, İşletme BölümüCrafting and executing the best cryptocurrency mining strategy is vital to succeeding in cryptocurrency market investments. This study aims to identify the best cryptocurrency mining strategy based on service providers’ performance for cryptocurrency mining using a hybrid analytics approach, which integrates the Analytic Hierarchy Process (AHP) and Fuzzy-TOPSIS techniques, along with sensitivity analysis. The results show that hosted mining is the overall best cryptocurrency mining strategy, followed by home mining and cloud mining, based on both total cost of operations and cryptocurrency payout criteria. The empirical findings also suggest that the critical features of the highest performing service providers (i.e., hosted mining strategies and cloud mining) were their flexibility of contracts and the superior efficiency in terms of the daily payout. Finally, of the three location alternatives for home mining, Turkey ranks first compared to the U.S. and Europe.Yayın Corporate board diversity and its impact on the socialperformance of companies from emerging economies(Wiley, 2021) Hacıoğlu, Ümit; Yılmaz, Mustafa Kemal; Abdallah Nantembelele, Fatuma; Sowe, Samba; Lisansüstü Eğitim Enstitüsü, İşletme Ana Bilim DalıGender diversity, and to a lesser extent cultural diversity, have become a focus of interest as predictors of corporate social performance. Based on a sample of 6150 observations from 1230 companies in 18 emerging economies, this article examines the influence of board cultural and gender diversity on three measures of corporate social performance: workforce, community, and product responsibility. Using structural equation modeling, it shows that the existence of board cultural and gender diversity positively affects the workforce, community, and product responsibility performance of companies. Concerning gender diversity, the results largely support other empirical studies. Our findings also contribute to the under-researched area of cultural diversity. This study adds value to the existing literature on corporate board diversity, and can be used as a guide for companies in their pursuit of diversity.
