Yayın Investigating the impact of mobile telecom service characteristics on consumer satisfaction in urban Uganda(SSBFNET, 2021) Manyaga, Fawz; Hacıoğlu, Ümit; Hacıoğlu, Ümit; Yönetim Bilimleri Fakültesi, İşletme BölümüThis paper aims to examine the impact of mobile telecom service characteristics on consumer satisfaction in urban Uganda, using a Servqual model. The association between customer satisfaction level and service quality characteristics has been tested with a regression analysis. In this study, assurance as a Servqualdimension has been substituted with tariffs to exhibit its effect on customers’ satisfaction levels. Findings verified that some of the Servqual dimensions including reliability, empathy, and responsiveness have been positively affecting the customer satisfaction level in the Ugandan context. The study also demonstrated that the prices of products and services of telecom companies were not the major concerns for telecom consumers in Uganda. The study, finally, provides some practical guidelines to managersof telecom companies as well as hinting out which Servqual dimensions are valued most by customers in Uganda.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 Assessment of technical and financial challenges for renewable energy project alternatives(Elsevier, 2024) Eti, Serkan; Yüksel, Serhat; Dinçer, Hasan; Kalkavan, Hakan; Hacıoğlu, Ümit; Mikhaylov, Alexey; Shah Danish, Mir Sayed; Pinter, Gabor; Hacıoğlu, Ümit; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Lisansüstü Eğitim Enstitüsü, İşletme Ana Bilim DalıThe purpose of this study is to assess technical and financial challenges for renewable energy project alternatives with a novel model. Firstly, a set of technical and financial challenges is created by considering the results of the literature evaluation. After that, the weights of these values are computed by Sine Trigonometric Pythagorean Fuzzy (ST-PFN) DEMATEL. The next step includes the ranking of six renewable energy alternatives with interval valued Spherical fuzzy multicriteria analysis with ratio and categorical data (SF MAIRCA) approach. Entropy and ARAS methodology are also considered to make comparative evaluation. Similarly, sensitivity analysis is also conducted for 10 different cases. It is concluded that the analysis results of all methods are the same. Therefore, it is identified that the findings of the proposed model are reliable and coherent. Identification of the most crucial technical and financial challenges of the renewable energy projects is the most important contribution of this manuscript. Furthermore, preferring the sine trigonometric structure in the proposed model will provide superiority to this model in many respects. It is concluded that difficulty in accessing finance for local projects is the most significant challenge for renewable energy investments. Moreover, competitive pricing of renewable sources is another critical issue in this regard. Additionally, it is identified that solar is the most successful renewable energy alternative to overcome technical and financial challenges.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.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.
