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 Bölümü
This 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.
The role of quality in airport services in passenger satisfaction at Aden Adde International Airport, Mogadishu, Somalia
(Bussecon International Academy, 2024) Farah, Nuh Abdulle; Hacıoğlu, Ümit; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Service quality is crucial for all service providers operating in the open market across all industries, particularly in the aviation sector, which produces billions of dollars in annual revenue from its services. The level of service quality significantly influences client satisfaction, and conversely, customer happiness reciprocally affects the service provider. In order to attain diverse company objectives, it is imperative to prioritize customer happiness specifically during the process of privatization. The primary objective of this research is to examine the influence of airport service quality on customer satisfaction within the context of a privatized airport. Descriptive and correlation analysis were utilized in the study. A total of 400 questionnaires were administered to passengers who embarked from Aden Adde International Airport as part of the study. Subsequently, the data was subjected to analysis utilizing a statistical software program designed for social science software (SPSS). The results of this analysis revealed a robust and positive correlation between Airport customer services and customer happiness. The study additionally revealed that a significant proportion of the airport's passengers expressed dissatisfaction with the services provided by Aden Adde International airport.
Optimizing passenger experience: A technological preference analysis in Turkish Airports
(Bussecon International Academy, 2023) Humza, Muhammad; Hacıoğlu, Ümit
Aviation-oriented companies are continuously seeking innovative approaches to enhance the passenger experience and operational efficiency within the industry. The objective of this study is to evaluate the categorization of passengers' technological preferences in Turkish airports. The objectives of this study are to enhance the understanding of Aviation Companies in Turkey regarding the technology preferences of passengers and their fundamental needs, as well as to analyze the characteristics of passengers that are directly linked to their technological choices. This study employs purposive sampling with a sample size of 455. Various statistical techniques, such as regression, correlation, and descriptive statistics, are employed to analyze the data. The findings indicate that biometric technology, personal device utilization, customisation and customization, as well as streaming and on-demand entertainment, greatly influence the technological preferences of travelers. Nevertheless, contactless solutions, inflight Wi-Fi, and mobile apps and digital services do not influence the technological preferences of travelers.
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 Bölümü
Crafting 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.
Investigating the impact of Covid-19pandemicon stock markets: Evidence from global equity indices
(SSBFNET, 2021) Hacıoğlu, Ümit; Faque, Mustapher; Yönetim Bilimleri Fakültesi, İşletme Bölümü
This paper aims to examine the impact of Covid-19 pandemic on stock markets. This paper also analyses the stock market cointegration of selected global equity indices that performed better and have a quick speed of recovery during the pandemic. This paper also questions how increasing uncertainty and volatility deters investors’ perception of the diversification of equity investments. The dataset for the selected 12 global equity indices has been used from Thompson Reuters’s EIKON database in a given period of time between 2010 and 2021. This paper employs Vector Error Correction Models to assess the relationship among the selected global equity indices. Findings demonstrate that (i) there is an adverse impact of Covid-19 on the Global Equity markets, (ii) there is a clear sign of cointegration in global equity indices, (ii) investors can benefit from investing in particular equity indices that have exhibited quick speed of recovery from the pandemic records lows. The findings finally provide a strong foundation for constructing a resilient equity portfolio in a highly uncertain market environment.
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 Dalı
Gender 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.

(Bussecon, 2025) Awe, Ya Neneh; Hacıoğlu, Ümit; Zehir, Melike; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Industry 4.0 technologies have optimized efficiency and effectiveness through the manufacture of sophisticated products and services, which result in enhancement of operations, improvement in safety, time, and cost-saving, and have revolutionized operations in almost all industries and have tremendously transformed the aviation sector. This study aims to examine the passenger travel experience with the implementation of e-services before, during, and after trips, from ticket bookings, self-check-in, smart boarding, in-flight services to baggage tracking after flight. Furthermore, the study seeks to identify the modern technologies with which air passengers are familiar or actively use, and to analyze the factors that influence their acceptance of these e-services. A research model was developed based on the extended Unified Theory of Acceptance and Use of Technology (UTAUT2) and modified to suit the objectives of this study. The study objectives were achieved through a survey, a self-administered online questionnaire from 253 air passengers was obtained, and data was analyzed using SPSS 25 software. The results reveal that performance expectancy, price-value, hedonic motivations, perceived benefits and habit have a positive significant influence on behavioral intention, while social influence, perceived challenges, facilitating conditions and effort expectancy were not supported. The results of the study give insights into how different passengers, different age groups, different geographical locations, and different technological maturity perceive such implementations. This will provide policymakers ideas on how to better manage and enhance e-services.
