Investigating the Impacts of Energy Consumption, Real GDP, Tourism and Trade on CO2 Emissions by Accounting for Cross-Sectional Dependence: A Panel Study of OECD Countries
(Routledge Journals, Taylor & Francis Ltd, 2017) Dogan, Eyup; Seker, Fahri; Bulbul, Serap
The objective of this study is to analyse the long-run dynamic relationship of carbon dioxide emissions, real gross domestic product (GDP), the square of real GDP, energy consumption, trade and tourism under an Environmental Kuznets Curve (EKC) model for the Organization for Economic Co-operation and Development (OECD) member countries. Since we find the presence of cross-sectional dependence within the panel time-series data, we apply second-generation unit root tests, cointegration test and causality test which can deal with cross-sectional dependence problems. The cross-sectionally augmented Dickey-Fuller (CADF) and the cross-sectionally augmented Im-Pesaran-Shin (CIPS) unit root tests indicate that the analysed variables become stationary at their first differences. The Lagrange multiplier bootstrap panel cointegration test shows the existence of a long-run relationship between the analysed variables. The dynamic ordinary least squares (DOLS) estimation technique indicates that energy consumption and tourism contribute to the levels of gas emissions, while increases in trade lead to environmental improvements. In addition, the EKC hypothesis cannot be supported as the sign of coefficients on GDP and GDP(2) is negative and positive, respectively. Moreover, the Dumitrescu-Hurlin causality tests exploit a variety of causal relationship between the analysed variables. The OECD countries are suggested to invest in improving energy efficiency, regulate necessary environmental protection policies for tourism sector in specific and promote trading activities through several types of encouragement act.

Glass Ceiling in Academia Revisited: Evidence From the Higher Education System of Turkey
(Routledge Journals, Taylor & Francis Ltd, 2021) Bulbul, Serap
Current study investigates the gender gap in academic promotions in Turkey taking a new perspective on the widely established existence of gender inequality in academia. The dataset includes the eight most-prominent research universities in Turkey and the nature of the 'glass ceiling' is explored by looking at the gendered distributions of: (1) academic seats -indicating academic performances, and (2) coauthorship patterns concerning genders. Findings suggest that there is gender disparity in academic performances as well as in academic promotions. In addition, gender is found to be a significant factor in explaining the current situation in academic ranks and subtle discrimination practices may exist instead of overt discrimination practices as it is also suggested in previous studies. In sum, results show two main points: (1) There is evidence of gender gap in academic promotions in Turkey, (2) A new variable -cross gender coauthorship- for glass ceiling research may provide further insight about the issue.
