    İşletmelerin Kurumsal Yönetim Uygulamalarının Finansal Performans Açısından İncelenmesi: Borsa İstanbul Kurumsal Yönetim Endeksi Şirketleri Üzerine Bir Uygulama
    (2025) Koy, Ayben; Güngör, Mehmet Yusuf
    This study examines the impact of corporate governance on financial performance in firms listed on the BIST Corporate Governance Index (BIST XKURY) over the 2010–2022 period using panel data analysis. The significance of the research lies not only in investigating this relationship but also in analyzing the role of female representation on board of directors. Corporate governance is evaluated across four dimensions: shareholders, transparency, stakeholders, and the board of directors. Financial performance is measured through ROA, ROE, and EPS, with firm size and leverage included as control variables. The sample is divided by a 25% threshold of female board members. The findings indicate that in firms with ≥25% female representation, the link between board effectiveness and profitability is stronger, highlighting the performance-enhancing role of gender diversity.

In this context, this study aims to examine the predictive roles of career adaptability and commitment to higher education institutions on university students' life satisfaction levels. Design/methodology/approach – This research was conducted using a quantitative research method. In this context, the survey method was preferred in the study. A total of 295 students from foundation universities from Istanbul participated in the study. Personal Information Form, Career Adaptability Scale, Student Commitment in Higher Education Scale and Life Satisfaction Scale were used to collect the data. The data were subjected to the normality test, reliability test, descriptive statistical analysis and regression analysis. Results – The results showed that the levels of career adaptability and commitment to higher education significantly predicted the life satisfaction levels of university students. Discussion – It seems possible to evaluate the university years as an exciting yet challenging process in which different experiences are gained for university students. In this process, universities can be considered as social structures that are expected to contribute to students' life satisfaction by supporting their academic and personal development. Increasing the capacity of university students to adapt to the changing business life can help them make informed decisions about their future professional lives. In addition, individuals with high student commitment may be more motivated than others to improve their career adaptation skills by actively participating in educational processes. This may create a sustainable development cycle that supports students' academic and professional success by increasing their life satisfaction and psychological well-being.

    Inequality and the Import Demand in Turkey
    (Istanbul Univ, 2021) Ozbay Das, Zuhal; Das, Zuhal Ozbay
    The study aims to see whether the long-run relation between inequality and import demand exists in Turkey. The Autoregressive Distributed Lag (ARDL) cointegration technique is used in this study to estimate the long-run relationships between real imports, income, relative price, real exports, and inequality for the period 1982-2015. The results revealed that the income elasticity of imports is greater than one as the literature suggests. The sign of the coefficient of relative price and its magnitude is also compatible with the literature, while it is not statistically significant. However, the results further reflect that inequality is positively associated with real imports in Turkey contrary to assumptions of the relation between inequality and imports that is found to be negative for lower income countries in some studies. Short-run coefficients reflect that real income and relative prices are associated with real imports, whereas exports and not surprisingly, inequality variables are not in the short-run. The coefficient of income parameter is less in magnitude in the short-run but still greater than one. However, the sign of the coefficient of the relative price turns out to be positive in the short-run.

    (Cordus, 2022) Teoman, Ezgi; Seren, Arzu Kader Harmanci
    AIM: Presenteeism means that employees feel obliged to go to work even if there is a real problem that they cannot work.The main purpose is to to adapt the "Stanford Presenteeism Scale-Short Form" into Turkish on Nurses. METHOD: This is a methodological study. The study sample included the nurses working at the medical and surgical clinics of two public hospitals in 2017 in Istanbul. A total of 290 nurses participated in the study. Language, content, construct validities, total item correlation analysis, Kaiser Meyer Olkin, Bartlett tests, confirmatory and explanatory factor analysis (EFA), stability, and Cronbach's alpha reliability analyses were tested. RESULTS: The content validity index of the scale was.92. Two items that have correlation values below.40 were removed from the Turkish form. Cronbach's alpha internal consistency coefficient was.762. The structure of the four-item and single-factor Turkish form was confirmed. CONCLUSION: Stanford Presenteeism Scale-Short Form is a valid and reliable tool for the nurses in Turkey. It is recommended to be used among nurses in different studies. Hospital and nursing care service managers should deal with "presenteeism," since it is becoming a critical health human resource workforce issue. Health care managers may use this tool to evaluate the presenteeism level of their employees.

    Measurement of Perceived Psychological Safety: Integration, Review and Evidences for the Scale in the Context of Turkiye
    (Istanbul Univ, Methodology & Sociology Research Center, 2022) Bulbul, Secil; Isiacik, Serin; Aytac, Serpil
    Psychological safety can predict many positive individual and organizational outcomes at work, and previous research addressed how psychological safety contributes to positive work attitudes and behaviors. In Turkey, there is quite an amount of research showing the contributing role of psychological safety perception on employees' positive performance behaviors and organizational effectiveness and innovativeness. However, previous research in Turkey does not adequately show the reliability and validity of the psychological safety scale, which was developed by Edmondson (1999). Based on the suggested requirement this study aimed to investigate the psychological safety perceptions of individuals who work in various sectors in Turkey. The adapted version of the psychological safety scale was used to gain evidence for the reliability and validity of the instrument in Turkey. In total, 585 individuals working in various industries and from various occupational groups participated in the research. Both exploratory factor analysis and the confirmatory factor analysis showed that Turkish adapted version of the psychological safety scale was valid and reliable.
