Article Citation - WoS: 1Citation - Scopus: 1Socio-Economic and Development Disparities Over the Long-Run: Exploring Spatial Heterogeneities in the Case of Turkey(Hungarian Central Statistical Office, 2024) Duran, Hasan Engin; Cifci, Burcu Degerli; Karabakan, Berfin; Dogan, FehmiThe aim of this paper is to explore the evolution of socioeconomic development and income disparities and convergence patterns across Turkish provinces, emphasizing the impact of spatial heterogeneities. We propose two types of contributions to the literature. First, most of the studies that apply the 13- convergence method presume a unique 13 parameter, assuming that all regions homogenously converge to the steady state at the same pace. However, we argue that relaxing this assumption by way of considering spatial heterogeneities might be more informative. Second, we provide a simple solution to a severe problem: The neoclassical model assumes a monotonic saddle path along which economic fluctuations are not considered, which might be particularly influential with regard to convergence when the time span is too short to capture long-term evolution. Many empirical studies cover only short periods, which may be easily dominated by recessions or expansions, significantly biasing the results. To overcome this problem, we look into two datasets covering long periods (1963-2017 and 1975-2021). Having applied various empirical methods, such as spatial regressions, GWR and nonparametric regressions, we obtain several results. First, at the country level, there is empirical evidence of regional convergence and decreasing development inequalities. Second, however, this convergence process is not valid in all areas. We conclude that there is nonnegligible spatial heterogeneity that should be taken into account in such analyses.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 Citation - WoS: 3Citation - Scopus: 3Assessment of Mutual Variation of Near-Surface Air Temperature, Land Surface Temperature and Driving Urban Parameters at Urban Microscale(Multidisciplinary Digital Publishing Institute (MDPI), 2023) Gerçek,D.; Güven,İ.T.The Urban Heat Island (UHI) effect is of critical concern for cities’ adaptation to climate change. The UHI effect shows substantial intra-urban variation at the city microscale, causing disparities in thermal comfort and energy consumption. Therefore, air temperature assessment should be prioritized for effective heat mitigation and climate adaptation. However, meteorological stations’ spatial distribution is far from meeting the scale that the UHI and its driving parameters operate. This limitation hampers demonstrating the intra-city variability of UHI and its origin of sources; for example, most studies employ Land Surface Temperature (LST), usually without demonstrating the relationship between UHI and LST. The current body of knowledge on urban climate implies a much better understanding and more detailed information on the spatial pattern of UHI and the driving factors to provide decision-makers with tools to develop effective UHI mitigation and adaptation strategies. In an attempt to address the adequacy of the use of LST and UPs in describing the intra-city variability of UHI, this study investigates the relationship between LST daytime and nighttime, and air temperature (Ta) daytime and nighttime, and driving urban parameters (UPs) of UHI together. Although it is well recognized that the intensity of the UHI is characterized by Ta, particularly at night, so-called nocturnal UHI, the use of remotely sensed LST is common, owing to the lack of spatially detailed Ta data in cities. Our findings showed that nocturnal UHI is weakly correlated with nighttime LST with a Pearson correlation (r) of 0.335 at p > 0.05 and that it is not correlated with daytime LST for the case study, highlighting the need for Ta observations for representing the intra-urban variation of nocturnal UHI. Among UPs, Sky View Factor (SVF), Building Volume Density (BVD), and Road Network Density (RND) explained 69% of the variability of Ta nighttime that characterizes nocturnal UHI. Therefore, UPs that performed well in estimating nocturnal UHI may be used in the absence of densely distributed Ta measurements. In a further investigation of the urban cooling phenomenon based on UHI diurnal changes, a particular region with high nighttime temperatures spoiled the Ta daytime and nighttime coherence. This region is characterized by high Mean Building Height (MBH), BFD, and BVD that re-emits heat, low SVF that prevents urban cooling, and high RND that releases extra heat at night. These particular UPs can be of prior interest for urban cooling. The present study, exploring the relationships of LST and Ta in a diurnal context, offers a further understanding of the preference of LST, Ta, or UPs to characterize UHI. Ta, in relation to major causative factors (UPs), provides insights into addressing the localities most vulnerable to the UHI effect and possible strategies targeting heat mitigation for sustainability and climate change resilience. © 2023 by the authors.Article Citation - WoS: 1Citation - Scopus: 1A Narrative of an Ideological Destruction: Where Do We Go Now?(University of Pittsburgh, 2023) Tunç Cox, Ayça; Aygün, GamzenurLebanese filmmaker, actress, and screenwriter Nadine Labaki’s 2011 film Where Do We Go Now? is about the ideological manipulation that gradually results in a big conflict among people in a rural Middle Eastern village where Muslims and Christians live in a peaceful existence. Labaki is known for her politically engaged narratives which refer to the recent political past of Lebanese whilst centralizing strong female figures. Where Do We Go Now? is no exception, and thus, reflects the director's general cinematic style and political attitude. Labaki invites her audience through the comedy to question ideology which interpellates and thus constructs the individual as a subject by revealing the ways ideology creates differences, separation, and conflict among people. In this context, this article strives to analyze the film Where Do We Go Now? employing critical discourse analysis with references to Althusser's conceptualization of ideology and Subject-subject formation. © 2023, University Library System, University of Pittsburgh.

Based on the continuous surveys of town and village development in Japan, South Korea, and China, this study aims to provide an overview of social policies that have been implemented in the past or more recently in these three countries in response to rural shrinkage, and to outline the core philosophy of these practices to cope with the repercussions. In this paper, we analyze the overall process of rural depopulation and the present features of town and village development in three countries. We subsequently present the social policies over the last few decades and summarize them into four major groups. Furthermore, we highlight that the focus of social policies is not to seek possible ways to reestablish growth but to provide positive support and effective reform to adjust and satisfy the changing needs of towns and villages under the circumstances of shrinking development, including the optimization of public resource allocation, exploring institutional innovation to valorize abandoned assets, and developing endogenous potentials for future sustainable development. Qualitative methods from a combination of literature review, policy review, and field surveys have mainly been adopted in this research. The study of East Asian practices may be instructive for other Asia-Pacific countries, as well as European countries that have been experiencing or will eventually face the challenges of rural shrinkage.Article Citation - WoS: 5Citation - Scopus: 5De-Sealing Reverses Habitat Decay More Than Increasing Groundcover Vegetation(MDPI, 2023) Couch, Virginia; Salata, Stefano; Saygın, Nicel; Frary, Anne; Arslan, BertanModeling ecosystem services is a growing trend in scientific research, and Nature-based Solutions (NbSs) are increasingly used by land-use planners and environmental designers to achieve improved adaptation to climate change and mitigation of the negative effects of climate change. Predictions of ecological benefits of NbSs are needed early in design to support decision making. In this study, we used ecological analysis to predict the benefits of two NbSs applied to a university masterplan and adjusted our preliminary design strategy according to the first modeling results. Our Area of Interest was the IZTECH campus, which is located in a rural area of the eastern Mediterranean region (Izmir/Turkey). A primary design goal was to improve habitat quality by revitalizing soil. Customized analysis of the Baseline Condition and two NbSs scenarios was achieved by using local values obtained from a high-resolution photogrammetric scan of the catchment to produce flow accumulation and habitat quality indexes. Results indicate that anthropogenic features are the primary cause of habitat decay and that decreasing imperviousness reduces habitat decay significantly more than adding vegetation. This study creates a method of supporting sustainability goals by quickly testing alternative NbSs. The main innovation is demonstrating that early approximation of the ecological benefits of NbSs can inform preliminary design strategy. The proposed model may be calibrated to address specific environmental challenges of a given location and test other forms of NbSs.Article Citation - WoS: 12Citation - Scopus: 12Economic Resilience and Regionally Differentiated Cycles: Evidence From a Turning Point Approach in Italy(Wiley, 2023) Duran, Hasan Engin; Fratesi, UgoThe literature on regional resilience often neglects the timing of recessions and simply uses national cycles. Region-specific cycles and turning points might bias the results, however, and affect the choice of regions to target with policies. This paper investigates the geography and determinants of regional resilience with a regional turning point approach, using data for Italy, a country with a well-known and sizeable regional divide. The results show that the timing of regional cycles varies substantially and that the detected resilience determinants are different across the two approaches, implying that the policy levers may be wrongly estimated with national turning points.Article Citation - WoS: 3Citation - Scopus: 4Region-Specific Turning Points in Territorial Economic Resilience: a Business Cycle Approach To Turkey(Routledge, 2023) Duran, Hasan Engin; Elburz, Zeynep; Kourtit, Karima; Nijkamp, PeterAlmost 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.Article Citation - WoS: 16Citation - Scopus: 20Application 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, FatmaThis 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.Article Citation - WoS: 11Citation - Scopus: 11Adapting Cities To Pluvial Flooding: the Case of Izmir (türkiye)(MDPI, 2022) Salata, Stefano; Couch, Virginia Thompson; Velibeyoğlu, Koray; Baba, Alper; Saygın, Nicel; Uzelli, TaygunIn the coming decades, climate change will be one of the most significant challenges for urban areas. The quantity, duration and intensity of events, such as flash rains and heat waves, will increase the vulnerability of urban regions while exposing citizens to potentially dangerous conditions. According to the current literature, mainstreaming resilience in urban planning means designing rules that strengthen urban systems’ adaptive and self-regulating functions by reducing their vulnerability. In this work, we aimed to build knowledge for the application of the sponge district concept to Izmir (Türkiye), one of Europe’s most vulnerable areas to pluvial flooding. To do this, we first analyzed the runoff in each urban sub-watershed, then employed a composite index to determine potential areas of intervention for nature-based solutions. Results show that 10% of Izmir’s urban areas are extremely vulnerable to cloudbursts, which means that 40% of the urban population is exposed to this phenomenon. Moreover, the runoff calculation in the sub-watershed demonstrated that the potential flood volume is underestimated, especially in the upslope areas. The results can be used as a template to suggest a stepwise approach to mainstream the resilience of densely-inhabited coastal urban catchments.
