    An examination of the impact of workplace incivility on employee performance
    (İbn Haldun Üniversitesi, Lisansüstü Eğitim Enstitüsü, 2023) Sowe, Samba; Arslan, Mahmut
    Incivility at the workplace has become a universal organizational phenomenon that deserves thorough investigation to understand it from various contextual lenses. It is a form of rude behavior that negatively impacts employees at the workplace hence the need to find solutions to solve it for better employee and institutional performance. In the spirit of investigating the universal phenomenon, this research aims to investigate the impact of workplace incivility (WPI) on employee performance (counterproductive work behavior and organizational citizenship behavior) through the mediating roles of psychological ownership (PO) and turnover intention (TI). Data for this research, with a sample of 504 respondents, was collected from public and private institutions in The Gambia and Ghana through a survey questionnaire. Structural Equation Modeling (SEM) was used to analyze the reliability and validity of our research model and hypotheses. The independent t-test results comparing The Gambia and Ghana have indicated a higher level of negative behavior among employees in Ghana compared to The Gambia as well as a higher level of positive behavior among employees from The Gambia compared to their Ghanaian counterparts. The study results indicate an indirect relationship between WPI to counterproductive work behavior (CWB) and WPI to organizational citizenship behavior (OCB) through PO. TI also plays a mediating role between PO to CWB and PO to OCB. The findings of this research will help public and private institutions in both The Gambia and Ghana assess the depth of incivility in their organizations as well as the negative impacts it may have on the performance of their organizations. This research is the first of its kind to make both a country and sector-level comparison of WPI and its impact on employee performance hence its significance.

    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.

    Exploring the impact of workplace incivility on employee counterproductive work behavior through the mediating role of turnover intention: Evidence from the Gambia and Ghana
    (CIKD, 2023) Arslan, Mahmut; Sowe, Samba; Yönetim Bilimleri Fakültesi, İşletme Bölümü
    Workplace Incivility (WPI) has recently become a dominant area of research as a predictor of employee behavior at work. WPI is a menace in the workplace that creates dissatisfied employees who spend most of their time on non-productive tasks. Based on a sample of 504 employees of public and private sector institutions in The Gambia and Ghana, this article examines the impact of workplace incivility on employee counterproductive work behavior through the mediating role of Turnover Intention (TI). Using structural equation modeling, the results indicate a strong relationship between workplace incivility and Counterproductive Work Behavior (CWB) as well as a partial mediating role of TI in the relationship between WPI and CWB. Furthermore, the independent sample t-test and multigroup analysis show a higher level of WPI, TI, and CWB in Ghana compared to The Gambia. These findings contribute to the under-researched area of WPI on the African continent. This study also adds value to the existing, but sparse, literature on workplace incivility and may also be used as a guide for public and private institutions in their pursuit of avoiding workplace incivility as well as knowing its effects on institutional productivity. Finally, this study is the first of its kind to look at the existence of WPI in both public and private institutions from The Gambia and Ghana making country comparisons as well as looking at the impact of WPI on the performance of employees hence its relevance to the literature.(c) CIKD Publishing.

    Towards sustainable cities: A sustainability assessment study for metropolitan cities in Turkey via a hybridized IT2F-AHP and COPRAS approach
    (Elsevier, 2022) Yılmaz, Mustafa Kemal; Kuşakcı, Ali Osman; Kuşakcı, Sümeyye; Sowe, Samba; Nantembelele, Fatuma Abdallah; Yönetim Bilimleri Fakültesi, İşletme Bölümü
    Accelerating trends of urbanization enforce the integration of sustainability principles into urban planning in a local scale to foster prosperity for the next generation of cities. This study incorporates fifty-three indicators on economic, social, environmental, and institutional dimensions to develop a Sustainable Cities Index (SCI) and assess the sustainability performance of thirty metropolitans in Turkey over 2010-2018. Turkish metropolitans constitute an appealing case study due to the rapid urbanization within the same time span. To answer how new metropolitans have been doing and whether they perform better than formerly declared metropolitans in Turkey, we propose a novel methodology with three stages that hybridizes Interval Type-2 Fuzzy Analytical Hierarchy Process (IT2F-AHP) and Complex Proportional Assessment of Alternatives (COPRAS). The former captures a high degree of uncertainty due to the subjective weight assignment by the experts, while the latter calculates aggregate scores for 30 cities. Finally, we conduct posthoc analyses to examine the significance of the urbani-zation policies in Turkey on the SCI scores. Thus, the study provides valuable insights into urbanization practices and encourages local administrations to spend more effort balancing the benefits and costs of public policies on sustainability.
