Book Review Mapping Detroit: Land, Community and Shaping a City(Taylor & Francis, 2015) Can, IşınMapping Detroit is not merely a book which depicts the physical transformation of a post-industrial city through various maps illustrating the causes of social and economical decline. With the significant contribution of the editors, urban designer Beckering, planner and community life observer Thomas and their colleagues, it makes a profound contribution to the subject of how spatial evolution of a city is brought about. Detroit, as it is discussed throughout the book, is an interesting case/model, not only among American cities but also in the different continents of the world. The introduction compares Detroit with other cities throughout the world, such as Berlin, Moscow and Birmingham among others, in terms of its spatial organization and population loss.Article Citation - WoS: 5Stormwater Management and Green Infrastructure Techniques for Sustainable Campus Design(Gazi Üniversitesi, 2011) Saygın, Nicel; Ulusoy, PelinThis study focuses on sustainable water resources management among extensive sustainable campus design principles. Water is a non-renewable asset for our increasingly arid geography due to reasons such as global warming. The sustainable approach to water resources consists of reclamation and capture of rainwater/stormwater, treatment and reuse of wastewater, protection and enhancement of groundwater quality and natural water bodies (creeks, streams, rivers, lakes and others) and creating water-efficient landscapes. Green infrastructure systems provide natural drainage and infiltration, prevent floods, improve water quality, and enhance ground water. In this study rainwater/stormwater is treated as a non-renewable resource instead of wastewater. This water resource can be captured and reused for different purposes such as irrigation, groundwater recharge, green corridors and landscape amenity by integration of rainwater/stormwater features into the site design. This study develops strategies for use of green infrastructure systems and recommendations to guide the implementation of these strategies. As a case study, first the current state of stormwater sustainability at Izmir Institute of Technology (IYTE) Campus, located in Gulbahce-Urla (Izmir), is discussed. Then, to improve and sustain the hydrologic balance, green infrastructure best management practices (BMPs) for IYTE School of Architecture grounds are developed as a pilot study of an ongoing masters thesis.Article Determining Scenario Based Highway Routes Using Geographic Information Systems; a Case Study of Simav-Kutahya Routes, Turkey(Pamukkale Üniversitesi, 2014) Erdem, UmutTransportation planning requires more efforts from city planners to use rational techniques to determine optimum road routes. To fulfill this requirement, this study aims at generating the cheapest and the shortest scenario based routes using Geographic Information Systems (GIS) and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Digital Elevation Model (DEM) with Least Cost Path analysis between the Simav and the Kutahya cities, and comparing them with existing routes. For generating the shortest and the cheapest route, these cities are selected as sample since the study region is located in the transition area between central Anatolia and Aegean Region which has access to the sea and regional ports. The methodology used in this study is composed of three parts: first part consists of two steps; (i) generating the factors and (ii) determining scenarios focusing on different transportation themes that are used in the study process. In second part all factors are weighed regarding scenarios. In the third part of the study the outputs Path A (cheapest) and Path B (shortest) are generated by Least Cost Path analysis. The output routes were compared not only with each other, but also with the existing routes in terms of the generated factors.Article Citation - WoS: 2Bölgesel İstihdam Dalgalanmalarının Şiddeti, Sebep ve Sonuçları: Türkiye Örneği(Yıldız Teknik Üniversitesi, 2017) Duran, Hasan Enginİktisadi “dalgalanma derecesi” veya diğer bir deyişle “oynaklık” (volatilite) sık ve şiddetli dalgalanan bir ekonomik yapıyı tanımlar. Günümüze kadar olan süreçte, bölge planlama ve iktisat literatüründe bu hususta araştırmalar yapılmış olsa da, istihdam dalgalanmalarının neden ve sonuçlarına, özellikle coğraf dağılımına ve bölgeler arası farklılıklarına çok az değinilmiştir. Bu çalışmanın amacı Türkiye’deki istihdam dalgalanmalarının sebeplerini araştırmak ve bölgeler arasında oluşan farklı dinamikleri ortaya çıkarmaktır. Diğer bir değişle, istihdam bakımından ülkemizinin hangi bölgeleri daha istikrarlıdır veya daha az şiddetli dalgalanmalara maruz kalmaktadır? Bu durumun altında yatan sebepler nelerdir? Bu sorular, TÜİK’in tanımladığı 26 Düzey-2 istatistiki bölge ve 2004-2013 dönemi için araştırılmıştır. Yöntem olarak, değişik panel regresyonları (Rassal Etki ve En Küçük Kareler yöntemi) ve zaman serisi metotları kullanılmıştır. Yapılan ampirik analizler sonucu iki temel bulgu elde edilmiştir. Birincisi, bölgeler arasında istihdam dalgalanma derecelerinin ciddi bir farklılaşma gösterdiğidir. İkincisi ise, bu durumun altında yatan faktörlerin çokça demografik ve piyasa büyüklüğü ile ilişkili olduğudur. Öyle ki, işgücüne katılımın yüksek olduğu bölgeler, nüfus ve istihdam bakımından büyük olan bölgeler ve ekonomik büyüme hızı ılımlı “ortalama-seviyede” olan bölgeler, daha istikrarlı bir istihdam görüntüsü çizmektedir.Article Citation - WoS: 2Arazi Kullanım - Ulaşım Planlaması Bütünlüğünde Uyum için Model Önerisi(TMMOB Şehir Plancıları Odası, 2018) Duvarcı, Yavuz; Alver, YalçınHer ne kadar kuramda ulaşım planlama ile arazi kullanım (nazım imar) planlama rutinlerinin birbirleriyle eşgüdüm ve uyum içinde hareket etmeleri gerektiği belirtilse de pratikte bunun pek gerçekleşemediği görülmüştür. Bu derleme çalışmasında özellikle olması gerektiği belirtilen uyumun gerçekleşememesinin ardındaki nedenler araştırılmış ve bunun nasıl sağlanabileceğine odaklanılmıştır. Sorunun kökeninde ise iki disiplinin birbirini takip eder ve benzer parametreleri paylaşır olmalarına karşın iki ayrı planlama alanı biçiminde ayrı prosedürler halinde planlamayı gerçekleştirmeye çalışmaları bulunmuştur. Ancak ideal durum olan (a) aynı anda birlikte planlamanın tek plan çalışması olarak gerçekleştirilmesi pratikte fazlaca uygulanabilir bulunmamış, yine, (b) aynı anda farklı planlama eylemleri olarak gerçekleştirilmeleri ve eş güdümlü olarak birbirlerinden beslenmeleri veri alışverişini aynı anda olanaksız kıldığından, genelde (c) ulaşım planlaması ile arazi kullanım planlamasının farklı zamanlarda birbirini takip eden ayrı planlama alanları olarak ortaya çıkması kaçınılmaz hale gelmektedir. Söz konusu ardışık ayrı (c türü) planlama eylem alanlarının temel sorunu ise birbirini karşılıklı besleyen bir döngü gibi görünse de uygulamada birbirine uyumlu gittikleri yalnızca ilkesel düzeyde kalmakta, retorikten öteye geçememektedir. Pratikte geçerli olan c türündeki uyumun sözde bir iyi niyet belirtisi olarak kalmaması ve gerçek uyumlandırmanın sağlanması için iki planlama alanının birbirini aktif olarak karşılıklı kontrol etmesi şartı aranmalıdır. Bu tür bir ilişki şemasının tesisinde, bir alanın (örneğin ulaşım planlamanın) politika hedeflerinin öteki alanın tanımlı çıktılarına (performans ölçütleri) uyumluluğu ve somut değerlerin belirlenen hedef değer aralıklarında çıkması gözetilmelidir. Bunlar somut kriterlere dönüştürülerek, modelleme çalışmalarında özellikle simülasyonlarda gözlenebilir sonuçlar üzerinden başarımları kontrol edilmelidir.Article Citation - WoS: 3Citation - Scopus: 2Sociospatial Segregation and Consumption Profile of Ankara in the Context of Globalization(Orta Doğu Teknik Üniversitesi, 2009) Akpınar, FigenThe ‘’Global City Hypothesis’’ argues that the economic restructuring of the new global economy produces highly uneven and polarized employment structure in urban society (1). Today, large global cities are marked by unusually high levels of income inequality. The significant increase in foreign investment and the arrival of the multi-national corporations along with the major accounting, advertising, and marketing firms and the fashion, design and entertainment industry caused changes both in spatial and demographic configuration and the internal structure of large metropolitan cities. The consequence of the economic restructuring is ‘class polarization’ characterized by a number of high income professionals and managerial jobs, and a vast population of low income causal, informal and temporary forms at the bottom. The effects of liberalization policies resulted in unprecedented fragmentation and polarization within the ‘middle class’ with the worsening public sector functionaries as some employees of the multinational firms had become wealthier (Kandiyoti, 2002, 5). This new wealth has engendered new social groups characterized as ‘young professionals’ or ‘new job elite’ with an increasingly educated cohorts of leading business with affluent lifestyles and consumption patterns similar to their global counterparts. Though such changes and processes occur to some extent in most developed world cities, the approach by the global city theorists seems to be accepted as the valid and elucidative pattern in general, and imposes a kind of generalization that in reality there are more counter evidences even in leading world cities and other metropolitan areas of the world which reveal different pattern (Maloutas, 2007, 734).Conference Object Detection of Urban Change Using Remote Sensing and Gis: Izmir Case(Taylor and Francis Ltd., 2008) Tarhan, Çiğdem; Arkon, Cemal; Çelik, M.; Gümüştekin, Şevket; Tecim, V.This study is an example of how land use changes could be detected via high resolution remotely sensed data. In order to perform "change detection" IKONOS satellite images, belonging to 2001 and 2004, have been used. An automated Graphical User Interface (GUI) has been created for detection of environment. Different image enhancement techniques and a fuzzy inference system have been combined in the GUI. The detection results are classified according to some basic levels such as 20-50% and 70%. Additionally, four different change detection algorithms have been applied which are pixel-based, object based, feature based. These algorithms have been examined according to change detection levels with different image enhancement techniques. At the end of the study, the results have been compared.Conference Object Citation - WoS: 1Citation - Scopus: 1Spatial Point Pattern Analysis of Lung Cancer in an Urban Area: Izmir Case(Taylor & Francis, 2013) Özkan, Sevim Pelin; Tarhan, Çiğdem; Eser, Sultan; Yakut, C.; Saygın, ÖmürIn health area, in order to conduct a reliable analysis of the diseases that threat public health and develop control strategies. This is required to investigate firstly how the disease are geographically distributed, secondly regions where disease is observed more dense, and thirdly their geo-statistical aspects. The aim of the study is to prepare spatially distribution map of the lung cancer cases in Izmir, Turkey, and are distributed on Izmir map via GIS. Spatial statistics are performed and the relations of geographical factors and the cancer data are discussed. Smart maps with tabular data and displaying cancer cases on a spatially distribution maps have been produced as end products. ArcGIS and Spatial Analyst module are used for the study.Article Citation - WoS: 18Citation - Scopus: 19A Suppressed Demand Analysis Method of the Transportation Disadvantaged in Policy Making(Taylor and Francis Ltd., 2009) Duvarcı, Yavuz; Mizokami, ShoshiThis paper proposes a method for estimating transportation supply requirements when the suppressed demand of the transportation disadvantaged (TD) can be calculated and added to existing demand for travel. The underlying assumption is that the travel conditions of these TD groups must be equal to the 'conventional' demand, known as 'full release'. Utilising the modelling approach for TD, suppressed demand analysis, diagnosis of difficulties and equity between conventional and disadvantaged groups were realised, while elaborating special cases for the most vulnerable TD groups (such as elderly and disabled persons) and simultaneously identifying areas of difficulty. From the early virtual results, it is concluded that, for the full release of suppressed trips (only a 5% increase), policy makers must be ready to face some financial burdens, requiring coordination of effort to both standardise these TD groups and reduce the costs incurred by operators.Article Citation - WoS: 1Citation - Scopus: 1The Multi-Level Policy Learning of Environmental Policy: Insights From Izmir(Routledge, 2019) Velibeyoğlu, Koray; Mengi, OnurA European Union (EU) membership perspective is important for Turkey's harmonization with EU standards, which could have positive outcomes especially in the area of smart environmental management. However, as recent political developments suggest, Turkey is losing hope of full EU membership, and is searching for alternatives, such as privileged partnership. Active contributions of city-level good practices are urgently needed. Policy learning is a part of this process, and an emergent result of ever-changing negotiations involving a multiplicity of actors at the multi-level perspective (MLP). The present study investigates the glocal environmental policy of Izmir, via a review of recent governmental environmentally sensitive local innovative practices. The findings reveal that innovative environments that increase learning-by-doing and learning-by-using will become critical for environmental policy learning in Izmir and perhaps beyond.
