Book Review Book Review: Post-Rational Planning: a Solutions-Oriented Call To Justice(SAGE Publications, 2023) Özdemir, Esin[No abstract available]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: 5Citation - Scopus: 4An Urban Plan Evaluation for Park Accessibility: a Case in Izmir (turkiye)(Palgrave Macmillan Ltd., 2023) Şenol, Fatma; Öztürk, Sevim Pelin; Atay Kaya, İlgiPlan 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.Article Citation - WoS: 8Citation - Scopus: 9The Distribution of City Sizes in Turkey: a Failure of Zipf's Law Due To Concavity(Wiley, 2021) Duran, Hasan Engin; Cieslik, AndrzejThe 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.Article Citation - WoS: 1Citation - Scopus: 1Groundwater Recharge Estiaton in the Alaşehir Sub-Basin Using Hydro-Geochemical Data; Alaşehir Case Study(Springer, 2021) Tonkul, Serhat; Baba, Alper; Şimşek, Celalettin; Demirkesen, Ali CanThe issue of groundwater recharge has gained importance in countries where there is not enough water supply to the aquifer. However, groundwater recharge is a difficult parameter to determine. This difficulty stems from factors such as the location of the area to be studied, time, cost, and hydrological data. Numerical, isotope, and chemical approaches are used in groundwater recharge investigations. Numerical and chemical approaches are more costly and time-consuming than chemical approaches. This study aims to ascertain alluvial aquifer recharge in Alaehir (Manisa) sub-basin using chemical approaches (Chloride Mass Balance Method) and its applicability. For this purpose, research wells were drilled at 25 different points in the alluvial aquifer, water sampling was done in wet and dry periods, and rainwater water samples were collected. Groundwater recharge was calculated by using chemical approaches from the chloride concentrations of the water samples collected. An annual average of 74.84 mm of recharge was found in the Alaehir sub-basin. This value corresponds to 16.38% of annual rainfall. At the same time, it was examined the groundwater and geothermal mixing mechanism to demonstrate the applicability of the Chloride Mass Balance Method. It was concluded that geothermal fluid in Alaehir sub-basin mixed with groundwater at a rate of 17%.Article Citation - WoS: 2Citation - Scopus: 2Regional Inflation Persistence in Turkey(John Wiley and Sons Inc., 2021) Duran, Hasan Engin; Dindaroğlu, BurakThe purpose of the current study is to investigate the degree of inflation persistence, its geographical variation, sources of cross-regional variation, and presence of geographical/sectoral aggregation bias in national monetary policy. Our data set covers 26 NUTS-2 level Turkish regions and monthly CPI inflation over the period 2003-2019. We first estimate the degree of regional inflation persistence by autoregressive regressions, check its robustness against the presence of structural breaks (by Bai-Perron's algorithm) and nonlinearities (by Markovian Regime Switching regressions). Second, we examine the possibility of geographical and sectoral aggregation bias. Third, we investigate the cross-regional determinants of inflation persistence by panel data analysis, employing hybrid-effects spatial panel regressions. We analyze the direct and indirect effects of the determinants and test for regional spillover effects. Three main results are obtained. First, estimated persistence degrees are heterogeneous across regions. The geographical pattern is empirically robust against structural breaks and nonlinearities. We find that inflation persistence is distributed in a spatially correlated manner. Second, when sectoral and regional aggregation bias is tested, only sectoral aggregation indicates a considerable level of bias. Third, we find that the presence of large firms in the region and a higher share of agricultural output in GDP leads to lower persistence, while an increased share of industrial output, and increased trade volume leads to higher inflation persistence. Moreover, we find spatial spillovers of price variability evident in regression analysis. From a policy standpoint, it is required that structural policy programs are targeted to maintain flexibility in the regions where persistence is high (i.e., providing market entry/exit, institutional quality, policy credibility, stimulation of SMEs). Moreover, sectors that have high persistence, such as Hotels and Restaurants (persistence degree 0.55) and Health Services (0.39) should be weighted more in CPI calculations.Article Citation - WoS: 4Citation - Scopus: 3Do Perceptions of Neighbourhood Change Match Objective Reality?(Routledge, 2020) Durmaz Drinkwater, Sıdıka Bahar; Platt, S.; Can Traunmüller, IşınThis study analyses neighbourhood change, its impact on the character of Soho, and to what extent perceptions of change match objective reality. Focusing on three streets (Berwick, Old Compton and Wardour Streets), the research (2008–2018) compares objective evidence of ground floor uses with the perceptions of people living and working in Soho. There was a close match between perceptions and objective measures of change on 4 out of 7 indicators: type of use, business name, locality and business ethnicity. The paper discusses these changes in terms of commercial gentrification that threatens Soho’s character. © 2020, © 2020 Informa UK Limited, trading as Taylor & Francis Group.
