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.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: 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. Delphi yöntemine göre yakınsama sağlanmış etkiler, sonrasında daha anlamlı ve özet sonuçlar elde etmek amacıyla toplamdaki etkiler yöntemiyle yeniden değerlendirilmiştir. Yönteme göre, mutlak toplam etkilere (MED), net toplam etkilere (NED) ve en genel anlamda etki yeterlik düzeylerine bakılarak genel sonuçlara ulaşılmıştır. 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: 5Citation - Scopus: 7Women Running for Neighborhood Offices in a Turkish City: Motivations and Resources for Electoral Candidacy(Elsevier Ltd., 2009) Şenol, FatmaThis study is about how gender and local urban scales interact with each other to influence individuals' motivations and resources for political recruitment. The data came from interviews with twenty women who ran for and lost the 2004 local elections for their neighborhood office, muhtarlik, in Eskisehir, Turkey. Considering both individual and institutional factors and the neighborhood scale as important for women's candidacy for local offices, this paper relies on a "relational" view of citizenship while examining the mediating roles of the local scale for citizenship. My findings overall disagreed with the arguments that "women's interests" drive women to enter politics and that the local offices provide more opportunities for women's political recruitment. As women's roles and responsibilities had been changing across multiple spaces, they ran for elections to search for ways to practice their capacities in public arenas. Yet to the electorates, first, even women with high qualities for the office did not appear as the most qualified candidates. Second, most electorates tended to evaluate candidacy qualities in relation to the neighborhood office's weak status in Turkish political system and as an unskilled job. Third, they seemed to associate this "job" positively with men's traditional domestic role as the main breadwinner, consider women's charity and communal works as women's traditional care responsibilities, and to vote mostly for over-middle-aged male incumbents with locally embedded relations. Finally, women missed an opportunity for their candidacy by not transforming their local network-based assets into resources for candidacy.Book Part Citation - WoS: 3Citation - Scopus: 4Spatial Transformations in Istanbul Cbd: the Role of Ict?(Information Science Reference, 2008) Geçer Sargın, Feral; Avar, Adile; Velibeyoğlu, Koray; Saygın, Mustafa ÖmürNow with the intensive use of information and communication technologies, many cities around the world are competing to become a global city. Istanbul is enumerated within the first 50 cities in the globalization process, other than the triad of New York, London, and Tokyo. This chapter explores urban space transformation of Maslak, the contemporary central business district of Istanbul, with respect to information and communication technologies, by using deconcentration and economic restructuring approaches of urban theory. Compared to other global cities, Istanbul has distinctive characteristics, since it has been passing through a unique transformation process. More specifically, its economic, political, and social characteristics distinguish Istanbul from other cities within the same category (Gamma) of world cities. This study has revealed that transformations in Istanbul were not primarily driven by information and communication technologies. In contrast information and communication technology's role in the transformation of the Istanbul central business district is only a contributing factor.Book Part Citation - Scopus: 7Understanding the Supply Side: Ict Experience of Marmara Region, Turkey(Information Science Reference, 2008) Velibeyoğlu, Koray; Yiğitcanlar, TanMarmara region's local governments in Turkey are setting the benchmark for the country in the implementation of spatial information systems and e-governance. The chapter aims to shed light on organizational realities of recent practices of information systems and technologies based on the evidences from selected local government organizations in the Marmara region. This chapter scrutinizes these practices and discusses the pivotal relationship between the information and communication technologies and its local organizational context within the region. The chapter also exemplifies challenges and opportunities of the Marmara as an emerging information and communication technology-supported region by illustrating the specific information and communication technology supply instruments. The chapter reveals that the particular success in supply side does not guarantee the sustainable information and communication technology implementation. There are other concerns including demand side that are strongly linked to a realistic understanding of end user demand, the institutional capacity of respected organizations, public-private partnership, and the joined-up policy efforts at both national and local levels.Book Part Citation - Scopus: 5Online Participatory Decision Support Tools for Knowledge-Based Urban Development(Information Science Reference, 2008) Yiğitcanlar, Tan; Saygın, Mustafa Ömür; Han, Jung HoonParticularly in the last decade, there have been a number of efforts to develop and then integrate planning support systems into existing geographic information systems. This integration brought a new technology called WebGIS, which enables geographic information systems functionalities through the Internet for decision support. No doubt there is a growing demand as more and more individuals want to use online government services to express their views and most importantly to take part in decisionmaking processes interactively. At this point, WebGIS offers a challenging opportunity for online participatory planning since the public could easily access alternative plans and the existing information in geographic information systems databases. This technology enables individuals to be able to take part in plan-making processes and contribute. This chapter explores how these new technological advances could achieve truly transparent plan-making process based on online participatory planning support tools that knowledge-based urban development could benefit from.Article Citation - WoS: 22Citation - Scopus: 28The Impact of Rail Transit Investment on the Residential Property Values in Developing Countries: The Case of Izmir Subway, Turkey(Emerald Group Publishing Ltd., 2006) Çelik, Hüseyin Murat; Yankaya, UğurPurpose The purpose of this paper is to test whether the rail transit investment in Izmir, Turkey has had positive valuation impacts on the surrounding residential properties, and to estimate the value of travel time using relevant parameters. Design/methodology/approach The necessary data were collected via a survey including all real-estate agents in the area. To test the research question, the Hedonic Price Model (HPM) is used as the research technique. The obtained parameters are also used to estimate the value of travel time. Findings The findings of the models has indicated that the proximity to rail stations was valued at $250-300 per meters, and the value of travel per hour was $1.47-1.83 on average. Research limitations/implications These findings should be checked with more consistent database using transaction process, and the mortgage loan rate which was not legislated at the time of study. Practical implications Until a mortgage loan rate is registered in turkey, the estimated parameters can be used in the cost-benefit analysis of rail transit investments in Turkey. Originality/value The theoretical premise that “any improvement in accessibility will be capitalized into the land values” is tested one more time in a developing country case whose urban environment is substantially different from those of the developed world, especially the North American cities. Furthermore, a new methodology using the HPM parameters is also suggested to estimate the value of travel time.Article Citation - WoS: 72Citation - Scopus: 101Knowledge-Based Urban Development: the Local Economic Development Path of Brisbane, Australia(SAGE Publications Inc., 2008) Yiğitcanlar, Tan; Velibeyoğlu, KorayKnowledge-based development strategies play an important role in supporting local economic development of cities in the knowledge era.
