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.Article Citation - Scopus: 10Asymmetries in Regional Development: Does Tfp or Capital Accumulation Matter for Spatial Inequalities?(Elsevier Ltd., 2019) Duran, Hasan EnginIn the literature on regional inequalities, commonly adopted Neo-Classical theoretical framework (Y=AK ? (hL) 1?? ) implies that disparities may arise for two reasons, either due to differences in factor endowments or TFP differentials. In the current study, we address the following rarely examined questions: i. Do regional income inequalities arise due to TFP or factor endowment disparities across regions? ii. What's their relative contribution to the level of and change in regional inequality? Our dataset covers the period 2004–2014 and 81 Turkish provinces. We use mathematical decompositions, Panel unit root, panel VAR and generalized impulse-response analyses. Results are summarized in two groups. First, the main contributor to income inequality is the disparity in regional factor endowments, whereas TFP differentials are relatively less influential. Second, the main source of decline in disparities seems to be the narrowing of TFP differences. © 2019 Elsevier B.V.Article Citation - WoS: 24Citation - Scopus: 25Prospects for Cellulosic Biofuel Production in the Northeastern United States: a Scenario Analysis(John Wiley and Sons Inc., 2016) Dilekli, Naci; Duchin, FayeSecure access to energy and food are two of the challenges facing the Northeast region of the United States. Traditional biofuel feedstocks, such as corn and oil seed, are able to satisfy energy requirements. However, they compete with food production for desirable land and water resources and, in any case, are not likely to exploit the region's current comparative advantages. This study investigates a potential solution to the energy security problem in the Northeast: biofuel from advanced feedstock in the form of net forest growth and woody wastes, of which the region has abundant endowments. The federal government has committed to requiring 79.5 billion liters (BL) of advanced biofuel production annually by 2022. We evaluate both the physical capacity for its production and its cost competitiveness using an input-output model of consumption, production, and trade in the 13-state region. The model minimizes resource use required to satisfy given consumer demand using alternative technological options and subject to resource constraints. We compile data from the technical literature quantifying state-level biofuel feedstock endowments and the technological requirements for cellulosic ethanol production. We find that exploiting the region's endowment of cellulosic feedstock requires either making the price of biofuels competitive with gasoline through subsidies or restricting imports of gasoline. Based on this initial investigation, we conclude that the region can produce significant amounts of advanced biofuel, up to 20.28 BL of cellulosic ethanol per year, which could displace nearly 12.5% of the gasoline that is now devoted to motorized transport in the region.Article Citation - WoS: 2Citation - Scopus: 3Integrating Spatiotemporal Dynamics of Natural Capital Security and Urban Ecosystem Carbon Metabolism(Springer Verlag, 2018) Demirkesen, Ali Can; Evrendilek, FatihThe purpose of the study is to address and quantify the increase in urban expansion and carbon (C) metabolism burden on ecosystem service value (ESV), net ecosystem productivity (NEP), and C storage of urban footprint. Urban footprint is required to meet the demands arising from economic consumption and production as well as waste accumulation and assimilation. Spatiotemporal changes in main land covers (LCs) were detected using remotely sensed data (Landsat 5 and 8, and digital elevation model) between 1987 and 2016. Changes in ESV and C influx, efflux and pools associated with LC dynamics were approximated using global proxies for a western Mediterranean region in Turkey of 54,162 km2. Urban expansion over the 29-year period decreased ESV by 22% ($7.28 ± 0.4 billion), NEP by 4.3% (2.3 ± 9 Gg C), and total ecosystem C pool by 10.9% (1008.3 ± 1006 Gg C) and led to a 62.8% appropriation of the total NEP (50.1 ± 51 Gg C) of the urban footprint in 2016. The main cause of the environmental degradation across the study region was the loss of the seminatural areas. Our findings emphasize that the deterioration rate of ecosystems should be slowed down by natural capital-friendly decisions and should not exceed rehabilitation rate of damaged ecosystems in the face of rapidly increasing burdens of the cities on their footprint.Article Citation - WoS: 21Citation - Scopus: 26Urban Crisis: ‘limits To Governance of Alienation’(SAGE Publications Inc., 2017) Bayırbağ, Mustafa Kemal; Penpecioğlu, MehmetThis article aims to develop a comparative framework of analysis to study urban crises, arguing that there is a need to establish the analytical links between ‘everyday life and systemic trends and struggles’, and thus to tie together the insights produced by ‘particularistic accounts’. It examines urban crises as political phenomena and brings the Marxist notion of ‘alienation’ to the centre of attention. We argue that ‘alienation’ – as a universal mechanism facilitating capital accumulation process via dispossession, and as negative mental/emotional implications of dispossession, is useful to establish those analytical links. We identify two domains, urban economic structure and urban political system, where alienation is contained. Public authorities deploy various containment strategies in these domains to govern alienation, and urban crises occur when these strategies fail. The post-2008 wave of urban upheavals could be explained by the failure of roll-out neoliberal strategies, which constitute the basis of our comparative framework.Article Citation - WoS: 3Citation - Scopus: 3Determining the Complexity of Multi-Component Conformal Systems: a Platoon-Based Approach(Elsevier Ltd., 2017) Koşun, Çağlar; Özdemir, SerhanMany systems in nature and engineering are composed of subsystems. These subsystems may be formed in a linear, planar or spatial array. A typical example of these formations is a chain of vehicles known as platoon formation in traffic flow. Platoon formation of vehicles is a linear or planar formation of vehicles where a certain and a constant headway, and sideway if applicable, is provided in between every and each one of them. It is argued in this paper that a well-automated platoon formation of vehicles is an extreme case of conformity. During this transformation from a many degrees of freedom formation to a solid object, Tsallis q value is computed to be ranging from one extreme case of q=3 to the other where q=1, when classified in terms of inverse temperatures of clearance fluctuations. At one extreme of q=3, one observes unbounded fluctuations in clearance fluctuations so that inverse temperature distributions approach a Dirac delta at the origin. At the other extreme of q=1, fluctuations in clearance tend to zero asymptotically, where a solid structure of agents (vehicles) emerges. The transition from q=3 to q=1 is investigated through synthetic and experimental clearance fluctuations between the cars. The results show that during the transition from q=3 to q=1, the platoon loses its many degrees of freedom (dof) of motion until a solid single object emerges. Authors assert that the Tsallis q value of a platoon of vehicles is limited to 3>q<1.Article Citation - WoS: 14Citation - Scopus: 15A Superstatistical Model of Vehicular Traffic Flow(Elsevier Ltd., 2016) Koşun, Çağlar; Özdemir, SerhanIn the analysis of vehicular traffic flow, a myriad of techniques have been implemented. In this study, superstatistics is used in modeling the traffic flow on a highway segment. Traffic variables such as vehicular speeds, volume, and headway were collected for three days. For the superstatistical approach, at least two distinct time scales must exist, so that a superposition of nonequilibrium systems assumption could hold. When the slow dynamics of the vehicle speeds exhibit a Gaussian distribution in between the fluctuations of the system at large, one speaks of a relaxation to a local equilibrium. These Gaussian distributions are found with corresponding standard deviations 1/β. This translates into a series of fluctuating beta values, hence the statistics of statistics, superstatistics. The traffic flow model has generated an inverse temperature parameter (beta) distribution as well as the speed distribution. This beta distribution has shown that the fluctuations in beta are distributed with respect to a chi-square distribution. It must be mentioned that two distinct Tsallis q values are specified: one is time-dependent and the other is independent. A ramification of these q values is that the highway segment and the traffic flow generate separate characteristics. This highway segment in question is not only nonadditive in nature, but a nonequilibrium driven system, with frequent relaxations to a Gaussian.Article Citation - WoS: 7Citation - Scopus: 7Energy Efficient Building Block Design: an Exergy Perspective(Elsevier Ltd., 2016) Mert, Yelda; Saygın, NicelThis study introduces the exergy analysis method into the field of urban planning, in order to find out the amount of energy that can be conserved in a building block when an energy efficient construction design is applied. This was done in four steps. First, energy efficient design parameters were derived from the literature and design alternatives were developed accordingly. Second, data was gathered from the case area for the exergy calculations. Third, exergy analysis of existing building blocks and proposed design alternatives were separately carried out. Finally, the amount of decrease in the exergy loss due to suggested energy efficient design was found out. The results show that the exergy efficiency of the existing building blocks is about 2%, while the proposed design alternatives will be around 10-11%. The overall exergy loads of the alternative plans were found as 166.3 W, 225.1 W, 142.5 W and 137.8 W respectively for winter and 105.4 W, 140.0 W, 89.9 W and 86.3 W respectively for summer, on a housing unit basis. As a result, the suitability and importance of the exergy analysis on the built environment was proven, by revealing actual and considerable energy conservation and sustainable use of energy through application of energy efficient design parameters.Other Corrigendum: Alienated and Politicized? Young Planners’ Confrontation With Entrepreneurial and Authoritarian State Intervention in Urban Development in Turkey(Routledge, 2016) Penpecioglu, Mehmet; Taşan Kok, TunaArticle Citation - WoS: 18Citation - Scopus: 18Alienated and Politicized? Young Planners’ Confrontation With Entrepreneurial and Authoritarian State Intervention in Urban Development in Turkey(Routledge, 2016) Penpecioğlu, Mehmet; Taşan Kok, TunaPlanning in Turkey is dominated by powerful market interests and authoritarian state regulation, resulting in a conflictual socio-political environment. Caught in the crossfire between interventionist urban policies and a planning education system that is oriented towards the public good, planners have come to feel alienated from their work. This paper considers how young planners respond to these challenges, drawing upon questionnaires and semi-structured in-depth interviews with planners with fewer than 10 years of experience. Their confrontation with entrepreneurial and authoritarian state interventions in urban development alienates them from their ideals, leading them to explore new ways of dealing with increasing political authority and economic neoliberalism. The participants of the study came up with a number of diverse responses related to this process. Disappointed with the practice of their profession ‘lost planners' begin searching for alternative pathways outside their practice towards a more meaningful society. In contrast, ‘profiteer planners' focus on getting more business and play a conformist and opportunistic role in the existing planning practice; while ‘struggling planners' develop alternative ways to pursue the public good by participating in urban movements. In short, they cope with alienation through politicization, solidarity and the identification of new means of engaging with society.
