    Region-Specific Turning Points in Territorial Economic Resilience: A Business Cycle Approach To Turkey
    (Routledge, 2024) Duran, H.E.; Elburz, Z.; Kourtit, K.; Nijkamp, P.
    Almost all regional economic resilience studies measure resilience by referring to national time patterns of recessions. This study of region-specific patterns of resilience of 81 Turkish regions in the period 2009–20 and their underlying economic/demographic determinants in regions in Turkey shows that ignoring the different timings of regional and national economy recessions leads to misleading/biased results. The study shows first that provincial employment cycles are asynchronous. Second, the geographical pattern of resistance to the last 2018 economic crisis changes considerably when using province-specific rather than national turning points. Third, those provinces that are more open to trade, export- oriented, highly urbanised, and with a low level of human capital and entrepreneurial activities were more resistant to the recession. © 2023 Regional Studies Association.

    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 Tugce
    Windows 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.

    Insights for the Enhancement of Urban Biodiversity Using Nature-Based Solutions: the Role of Urban Spaces in Green Infrastructures Design
    (Springer, 2022) Ronchi, Silvia; Salata, Stefano
    Nature-Based Solutions (NBS) increase their efficacy if included in an overall framework such as Green Infrastructures (GI), maximising ecosystem benefits and avoiding possible negative externalities and trade-offs. Urban green spaces and NBS are components of GI that increase the quality of urban settings, enhancing territorial resilience, and improving the health and well-being of citizens. The research proposes a methodology, tested in the municipality of Settimo Torinese (North-west of Italy), for selecting urban green spaces with high performance in terms of biodiversity conservation, which can involve a GI strategy as a multifunctional structure that combines different Ecosystem Services (ES). The enhancement of natural capital and ES provision is reached identifying suitable NBS to protect and improve biodiversity based on the Habitat Quality (HQ) assessment, considered a key supporting service. HQ was derived testing two different sensitivity data: the first based on Land Use/Land Cover, while the second uses the Normalised Difference Vegetation Index. The latter was functional to overcome limits in representing the ecologic integrity of urban areas highlighting an important variety of green spaces and related ES, especially in compact cities. The results are useful for defining effective environmental policies and strategies in urban areas and addressing the decision-making process towards sustainable development goals. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

    Region-Specific Turning Points in Territorial Economic Resilience: a Business Cycle Approach To Turkey
    (Routledge, 2023) Duran, Hasan Engin; Elburz, Zeynep; Kourtit, Karima; Nijkamp, Peter

    An Urban Plan Evaluation for Park Accessibility: a Case in Izmir (turkiye)
    (Palgrave Macmillan Ltd., 2023) Şenol, Fatma; Öztürk, Sevim Pelin; Atay Kaya, İlgi
    Plan evaluations about park accessibility are rare at the neighbourhood scale. Moreover, urban plans traditionally identify park accessibility with predetermined measurements that may ignore limited walking conditions of children, the elderly, women with children, and low-income groups. Alternatively, this paper considers equitable (rather than equal) park accessibility as an important goal concerning environmental justice. To guide a path to achieving this goal, it investigates how to assess and revise urban plans with parks within walking distance to social groups in the case of a plan (1/1000 scale) in Izmir (Turkiye). Deployment of the location-allocation analysis (a multi-criteria assessment methodology in Geographic Information Systems, GIS) allows this research to consider physical/geographical barriers to walkability in actual neighbourhood settings and reconfigure such barriers as contextual variables, including limited walking distances of disadvantaged groups. Ultimately, this study also contributes to how to handle spatial and demographic data deficiencies in Turkiye when measuring equitable accessibility of public facilities by walking. Results identify an uneven distribution of park accessibility even within the neighbourhood on the plan and the potential for improving park accessibility by designing some non-park public lands with park features.

    Application of Space Syntax in Neighbourhood Park Research: an Investigation of Multiple Socio-Spatial Attributes of Park Use
    (Routledge, 2023) Can Traunmüller, Işın; İnce Keller, İrem; Şenol, Fatma
    This case study investigates the actual park use as determined by the socio-spatial attributes of neighbourhoods and parks. As a contribution to the research about park accessibility, it integrates the space syntax analysis with the observation-based fieldwork data about the attributes of neighbourhoods, parks, and park users in 42 parks of 2 adjacent neighbourhoods in Izmir City (Turkey). With its syntactic measures (connectivity, integration, and choice), the study analysis describes the street configuration around these neighbourhood parks. Also, 3 multiple regression analyses are deployed to examine how the syntactic data along with the other neighbourhood and park attributes affect the number of users observed in 42 parks. The study contributes to the research about space syntax tools for analysing the organisational logic of parks in the neighbourhoods while also integrating other socio-spatial attributes of parks.

    An Evaluation of Measuring the Publicness Level of Interiors in Public Building Design: Visual Graph Analysis (vga) Approach
    (IGI Global, 2021) Aykutlar, Pelin; Kutucu, Seçkin; Can Traunmüller, Işın
    This study examines the publicness level of the interior spaces of public buildings. As a method, VGA (visual graph analysis) is used for analyzing the early design phases of selected municipal service buildings. In this study, the authors utilized from VGA for quantifying the publicness level of the two selected architectural competitions of municipality buildings. The method allows us analyzing the floor plans of each project in obtaining an eventual assessment of permeability and accessibility which give an idea of the levels of publicness comparatively. Subsequently, representation parameters are compared under two main criteria: connectivity and integration. The aim of the study is to understand the level of publicness and efficiency of spatial settings for the users circulating in the public buildings, which have dissimilar plan schemes. This method would be used by the designers for early design stage and provide useful feedback for understanding the level of accessibility and permeability of the structures and adjust their schemes accordingly.

    The Distribution of City Sizes in Turkey: a Failure of Zipf's Law Due To Concavity
    (Wiley, 2021) Duran, Hasan Engin; Cieslik, Andrzej
    The linearity of the distribution of city sizes is often assumed in the existing literature. Although different functional forms were tried, almost all of them impose a certain functional shape. In this study, we investigate the urban hierarchy and Zipf's law using data for 973 Turkish subprovincial cities in 2019. We contribute to the literature in several ways. We force no definite functional form to observe the natural shape and employ nonparametric and quadratic regressions. We incorporate formal procedures of spatial dependence in regression models. We demonstrate that the linear model overestimates the Pareto exponent for small cities and underestimates it for bigger cities. We show that city sizes are unevenly distributed in Turkey. The rank-size rule is not valid in Turkey, either above or below a certain city-size truncation level. Thus, the Pareto exponent estimated from the linear model is not a reliable indicator as quadratic regressions perform much better.

    Gis-Based Mappings of Park Accessibility at Multiple Spatial Scales: a Research Framework With the Case of Izmir (turkey)
    (Routledge, 2021) Şenol, Fatma; Atay Kaya, İlgi
    With a concern of social needs in the redistribution of benefits of parks, recent research assesses park accessibility but usually at one spatial scale (e.g. city, neighbourhood, or park). As a case in Izmir (Turkey), this study explores how to develop research with a multi-scalar focus on park accessibility. It proposes a framework with the research stages deploying GIS-based tools. The first stage identifies park-rich, park-moderate and park-poor neighbourhoods. The second and third stages evolve in three park-rich neighbourhoods and at 112 local parks. All stages deal with preparing various socio-spatial data from online sources and field observations and assess the data according to a list of themes about accessibility and diversity. The results highlight that regardless of their high park coverages per person, park-rich neighbourhoods have multiple blocks, buildings, and parks with the features hindering park accessibility for some local groups with different walking capacities and needs. The GIS-based mappings of these features can provide decision-making tools about local parks and neighbourhood interventions.
