Article Citation - WoS: 2Citation - Scopus: 2Spatial Analysis of Regional Income Inequality in Eu Countries(Taylor & Francis, 2024) Niknam Khajepasha, Alireza; Gkartzios, MenelaosThis article analyses regional convergence and the diminishing regional disparities within the EU27 from 2000 to 2019. It assesses the impact of income fluctuations on regional inequality by employing secondary analysis of income per capita indicators across NUTS 3 level regions. The article provides a quantitative assessment of regional income inequality, encompassing the most prevalent instruments used in the analysis of inequality data. In particular, it determines EU regional disparities using constructed Theil, Gini and CV indices exposing a more comprehensive evaluation of regional disparities within the EU. It also examines the nexus between spatial effects on regional income inequality. The findings suggest that EU convergence persists at the NUTS 3 level, albeit at a decelerating pace. We also point to the role of clustering effects among neighbouring regions. Notably, the study highlights the diminishing role of regional clustering due to income inequality during the ongoing convergence process.Article User Satisfactions on Visual Comfort and View Quality Based on Colours and Opacity of Glazing To Control Daylighting(Znack Publishing House, 2023) Cogul, Ilgin; Duran, Hasan Engin; Kazanasmaz, Zehra TugceWindows are both components that open to the outside and gates that bring the outside elements inside as well. The visible view through windows affects users' perception of the indoor environment. Visual comfort is a key concern to create qualified interior spaces. Glazing type in naturally lit environments becomes very substantial for comfort. As glazing technologies develop, the options available for users have also increased. This study aims to find out how different glazing and view types impact user perception and satisfaction in the interior and to create design ideas for the spaces to be completed in the future. A room with various glazing transmittance (20 %, 50 %, and 90 %), colours (blue and yellow), and view types (street and landscape) are modelled virtually in Relux. A survey composed of these rendered scenes from these variations includes four questions. 40 people participated in the survey. Statistical analyses are made using Stata and EViews. Illuminance and luminance are calculated via Relux to discuss quantifiable values and subjective one together. According to the results, as transmittance increase, the rate of people finding the room pleasant and the quality of the view decrease, but a brighter environment shows up. When using tinted glazing, users mark the rooms as interesting, while pleasantness and view quality decrease. A landscape view instead of a street view in the rooms results is a more interesting, pleasant indoor environment, and higher view satisfaction.Article Citation - Scopus: 1Spatial Effects of Air Transport on Regional Development : Evidence From Turkey(Fabrizio Serra editore, 2020) Nijkamp, Peter; Pels, Eric; Elburz, ZeynepThe rapid rise of aviation (including airport infrastructure) has prompted various research and policy questions on its socio-economic impact on spatial development of regions. Since the aviation industry facilitates a worldwide transportation network for business and tourism, it is considered to be a critical factor for economic growth. This study aims to analyze the relationship between air transport and regional development in Turkey, by using air passenger volume and regional employment data by means of both non-spatial and spatial regression methods. We run a Two-Stage Least Squares (2SLS) regression model with instruments to capture endogeneity, and Generalized Spatial Two-Stage Least Squares (GS2SLS) models to control for the spatial context by using data from 81 Turkish NUTS 3 regions (provinces) between 2008 and 2017. We extend the existing literature by measuring spatial spillover effects of air transport on regional growth. To the best of the authors' knowledge, this study is the first attempt to examine this link by considering both spatial effects and endogeneity problems. The results confirm our hypothesis that air transportation is an important determinant of regional employment in Turkish regions while the impact of air transport on regional employment decreases when spatial effects are taken into consideration.
