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.Article Citation - WoS: 3Citation - Scopus: 4İzmir’deki Ulaştırma Projelerinin Kentsel Eğilimlere Etkileri(TMMOB İnşaat Mühendisleri Odası, 2008) Duvarcı, Yavuz; Selvi, Ömer; Günaydın, Hüsnü Murat; Gür, Güneşİzmir’deki önemli ulaştırma projelerinin kentsel eğilimlere olan etkileri Delphi yöntemi sonuçları temel alınarak analiz edilmiştir.

En etkili (olumlu/olumsuz yönde) projeler, bütünleştirilmiş raylı toplu taşıma sistemi, mevcut İzmir limanının geliştirilmesi; en fazla etkilenen sosyoekonomik eğilimler ise turizm sektöründeki gelişim, ekonomik gelişme, hava kirliliği ve özel araç kullanım oranı olarak çıkmıştır.Article Citation - WoS: 3Citation - Scopus: 5Groundwater in Local Development Strategies: Case of Izmir(IWA Publishing, 2018) Velibeyoğlu, Koray; Yazdani, Hamidreza; Baba, AlperThis study takes into account groundwater in local development strategies of Izmir, in which rapid and uneven development has occurred in recent decades. Therefore, resilience thinking is needed in the future development of the city-region. To this end, the paper aims to make an analysis of recently completed asset-based local development strategies for Izmir city towards water resiliency. The methodology has two main steps. Firstly, by using spatial interaction analysis of peninsula and river basins, potential vulnerabilities and risks are indicated. Secondly, a stratified model of strategy evaluation is conducted by scrutinizing the existing layered approaches. Then, these models were applied to all strategic decisions including water resources and indicated a high level of consistency to achieve sustainable and resilient use of blue-green infrastructure in the future of Izmir’s metropolitan area. Local assets, including water resources, are the backbone of future development of the Izmir city-region. Therefore, usage of local assets in a multi-level perspective of strategy development needs to be understood. The stratified model denotes that special emphasis should be given to different river basins in different levels. This study illustrates that synergy management is needed between different layers of local development strategies, in which the role of urban and rural households is of the utmost importance.Conference Object Citation - WoS: 17Citation - Scopus: 21Place Management of a Creative City: the Case of Izmir(Inderscience Enterprises Ltd., 2017) Mengi, Onur; Durmaz Drinkwater, Sıdıka Bahar; Öner, Aslı Ceylan; Velibeyoğlu, KorayThis study investigates how place management is used to render a creative city through the combination of soft factors as intangible characteristics and hard factors as tangible characteristics of the built environment. The study focuses on Izmir, Turkey; exploring its potential as an emerging creative city. The methodology is a descriptive analysis of recent urban design and planning activities of creative cities, reviews projects and strategies in Izmir. Findings provide a framework for place management tools and their strategic use for integration of art, design, creativity and knowledge in creative cities. Place management is used as a tool for image building and identity enhancement, and for quality of place to attract creative and knowledge workers. In the case of Izmir, hard factors triggered the formation process whereas soft factors have taken strengthen the initiative. However, both of them are yet not strong enough to creative public awareness and critical mass.Article Citation - WoS: 2Citation - Scopus: 2Exergy Analysis of Mass Housing Areas: Mavişehir I and Ii, Izmir(Inderscience Enterprises Ltd., 2015) Mert, Yelda; Saygın, NicelIn this study, in terms of urban design, an exergy analysis of Mavişehir mass housing area in Izmir, Turkey is carried out based on spatial properties, shadow effects, wind effects and local climate to understand the importance of design strategies. The exergy analysis is applied with broad consideration covering the heat loads of the separate buildings for winter and summer. When the exergy results of Mavişehir I and Mavişehir II are compared it is found that Mavişehir II has less exergy by fuel and exergy load values. This may result from different design strategies in Mavişehir I where the same buildings and villas between residential buildings are located according to sea view, whereas in Mavişehir II, there is a heterogeneous pattern with various forms and heights of the residential buildings. It was also discovered that exergy efficiency of the area is 4.20% and the exergy flexibility factor is 19.3%.Article Citation - WoS: 17Citation - Scopus: 21An Evaluation Methodology for the Tangible and Intangible Assets of City-Regions: the 6k1c Framework(Inderscience Enterprises Ltd., 2010) Velibeyoğlu, Koray; Yiğitcanlar, TanTogether with hard and soft networks, tangible and intangible regional assets play an important role in the knowledge-based development of competing city-regions. The aim of this paper, therefore, is to investigate the best ways of managing invaluable tangible and intangible assets of city-regions. The paper explores the importance of asset management of city-regions by giving special emphasis on their knowledge asset base. This paper develops and introduces a theoretical framework to conceptualise a new approach to articulate the strategic planning mechanism, so called the 6K1C framework. The 6K1C framework is part of the strategic planning process of continuous improvement of overall public sector performance. The framework provides a proactive check-list approach integrated for managing and harnessing tangible and intangible assets of the post-industrial city-regions.Article Citation - WoS: 2Citation - Scopus: 2Soft Computing and Regression Modelling Approaches for Link-Capacity Functions(Czech Technical University in Prague, 2016) Koşun, Çağlar; Tayfur, Gökmen; Çelik, Hüseyin MuratLink-capacity functions are the relationships between the fundamental traffic variables like travel time and the flow rate. These relationships are important inputs to the capacity-restrained traffic assignment models. This study investigates the prediction of travel time as a function of several variables V/C (flow rate/capacity), retail activity, parking, number of bus stops and link type. For this purpose, the necessary data collected in Izmir, Turkey are employed by Artificial Neural Networks (ANNs) and Regression-based models of multiple linear regression (MLR) and multiple non-linear regression (MNLR). In ANNs modelling, 70% of the whole dataset is randomly selected for the training, whereas the rest is utilized in testing the model. Similarly, the same training dataset is employed in obtaining the optimal values of the coefficients of the regression-based models. Although all of the variables are used in the input vector of the models to predict the travel time, the most significant independent variables are found to be V/C and retail activity. By considering these two significant input variables, ANNs predicted the travel time with the correlation coefficient R = 0:87 while this value was almost 0.60 for the regression-based models.Article Citation - WoS: 2Citation - Scopus: 1Significance of Rent Attributes in Prediction of Earthquake Damage in Adapazari, Turkey(Czech Technical University in Prague, 2014) Tayfur, Gökmen; Bektaş, Birkan; Duvarcı, YavuzThis paper analyses rent-based determinants of earthquake damage from an urban planning perspective with the data gathered from Adapazari, Turkey, after the disaster in 1999 Eastern Marmara Earthquake (EME). The study employs linear regression, log-linear regression, and artificial neural networks (ANN) methods for cross-verification of results and for finding out the significant urban rent attribute(s) responsible for the damage. All models used are equally capable of predicting the earthquake damage and converge to similar results even if the data are limited. Of the rent variables, the physical density is proved to be especially significant in predicting earthquake damage, while the land value contributes to building resistance. Thus, urban rent can be the primary tool for planners to help reduce the fatalities in preventive planning studies.
