    A Novel Approach by Combining Fuzzy Ahp and a Simulation Model To Analyze Suitability of Ports for Offshore Wind Farms
    (int Soc offshore Polar Engineers, 2025) Ozturk, Samet; Karipoglu, Fatih; Efe, Burak
    This study presents a comprehensive suitability analysis for assessing the serviceability of existing container ports for offshore wind farms (OWFs) in Turkey, utilizing a combination of fuzzy analytical hierarchy process with Arena simulation modeling. This study is the first comprehensive analysis of offshore wind port infrastructure that integrates a multi-criteria decision making process with an Arena simulation model tailored specifically for existing container ports. The results indicate that technical criteria are deemed most critical, carrying the highest weight (0.563), with expansion potential identified as the most impactful criterion within the technical category. In addition, the study employs the Arena simulation software to forecast the operational workload on the most suitable ports following potential OWF installations.

    Exploring the Contemporary Dynamics of Extended Urbanisation: a Comprehensive Analysis on the Case of Denizli, Turkey
    (Kare Publ, 2025) Kolaoglu, Busra; Penpecioglu, Mehmet; Ogur, Aysun Ayguen
    Contemporary discussions about extended urbanization and its inherent practices of suburbanization particularly focus on metropolitan cities in the Global South. There is inadequate empirical evidence on the rapidly developing Anatolian cities in Turkey. To address this gap, this article analyzes Denizli's extended urban development process, elaborates on the dominant practices, and examines the driving forces shaping its rapid, contested, and fragmented socio-spatial landscape. As one of the most ubiquitous cases among rapidly developing Anatolian cities, Denizli highlights the leading role of fragmented urban development planning interventions, the stimulating impact of transportation and infrastructure investments, and the pivotal role of private sector projects. The research consists of urban spatial analysis using statistical data and urban planning documents, detecting land use/cover changes over time, and identifying the driving factors that have influenced and shaped the patterns of urban development in Denizli. The findings indicate that fragmented urban development planning interventions have both triggered and sustained extended urban development in Merkezefendi, Denizli. Moreover, key public investments and real estate projects have fostered this extended urban development process, leading to disjointed fragments in a socioeconomically polarized geography. As a diversified and relational formation of extended urbanization, Denizli provides genuine research findings, and includes remarkable similarities as well as differences in the comparative analysis of global urbanism practices.

    Exploring Student Information Management System Adoption Post Pandemic: Case of Turkish Higher Education
    (Elsevier Ltd, 2024) Daim,T.; Ozdemir Gungor,D.; Basoglu,N.; Yarga,A.; VanDerSchaaf,H.
    Many aspects of our lives have changed during the pandemic including the accelerated adoption of technologies. Education was one of the segments that was disrupted by the pandemic, therefore Student Information Systems became critical at that time. This paper explores the adoption of Student Information Management Systems in multiple Turkish universities. The research model was adopted from a study conducted in the US, which is based on the Unified Theory of Acceptance and Use of Technology. More than three hundred students from seventeen universities responded, and the results indicated key factors of adoption. Furthermore, differences with the case in the US were identified. © 2024 Elsevier Ltd

    Politics of Waiting for Transformation in Protracted Urban Renewal Projects in Turkey
    (Sage Publications Ltd, 2023) Ay, Deniz; Penpecioglu, Mehmet
    This paper explores the politics of 'waiting' as a mode of governance in large-scale urban redevelopment projects. In designated renewal areas, residents/landowners are often subject to several episodes of waiting: waiting for the public authority for information on redevelopment visions; waiting for the plans and projects to become public; waiting for the court ruling if they appeal the plans; waiting for demolition upon plan approvals; and, finally, waiting for the constructions to be completed. Given the complexity of actors and institutions involved in the waiting, it becomes a conflictual political process. This prolonged waiting leads to an ongoing temporariness and precarious spaces of urban renewal. The course of waiting affects the reorganization of the city space now and in the future. We analyze two protracted urban renewal projects from Turkey, Fikirtepe in Istanbul and Karabaglar in Izmir, to explore how residents' decade-long waiting for urban change are shaped and how these diverse waiting experiences lead to different outcomes for the progression of the state-imposed urban renewal agendas. While Karabaglar residents have unified around active bottom-up resistance from the beginning to challenge the project-based plans the central government imposed, Fikirtepe residents pursued individual-level negotiations with developers to maximize private returns following the zoning incentives the public authority gave. Despite the socio-spatial similarities between these designated urban renewal project sites, variances in residents' collective waiting strategies have led to different urban politics around project-based urban change.

    A Gis-Based Fahp and Fedas Analysis Framework for Suitable Site Selection of a Hybrid Offshore Wind and Solar Power Plant
    (Elsevier B.V., 2023) Karipoğlu, Fatih; Ozturk, S.; Efe, B.
    This study presents a Geographic Information System (GIS) based suitable site selection methodology for a hybrid system that includes offshore wind and solar PV. The methodology utilizes open source databases about decision criteria and applies this data using GIS to determine suitable sites for offshore wind and solar PV systems. For the assessment of multi-criteria which affect the potential hybrid energy power plants and the determination of the best suitable areas, Fuzzy Analytical Hierarchy Process (FAHP) and Fuzzy Evaluation based on Distance Average Solution (FEDAS) are used in the study. Results show that technical criteria has the priority weight of 0.60 while the weight of social criteria is about 0.07. Among sub-criteria, the wind speed has the highest priority weight while distance to port and visibility are the highest criteria of priority weight under economic and social main criteria, respectively. Among the alternatives, Area 2 (A-2) is determined as the best alternative for hybrid offshore power plants in the study area. This proposed methodology can be utilized by decision-makers to determine the best suitable locations for hybrid offshore wind and solar PV systems at any location. This paper suggests a new approach integrating GIS, fuzzy setbased AHP and EDAS as a novelty. © 2023 International Energy Initiative

    Revisiting the Turkish-Israeli Alliance of the 1990s
    (Routledge, 2023) Elhan, N.; Şirin, B.
    The Turkish-Israeli ‘honeymoon’ of the 1990s has been explained by different concepts such as alliance, strategic partnership, or cooperation and friendship, with these concepts often used interchangeably. As a corollary of the Turkish official narrative, which is based on a national security approach, certain explanations were offered in justification of the close relationship, including shared traditional democratic culture and secular character, as well as conducive international atmosphere. According to this construction, Turkey had no option but to align with Israel. On the other hand, while the ‘honeymoon’ was often seen as a foreign policy issue directly affected by the military bureaucracy, negative discourses against Israel in domestic politics, and institutional challenges in the Turkish state structure were often ignored. By way of filling this lacuna, the present article evaluates the impact of domestic factors, including the capital-owning class, lobbies, and institutional changes in the Turkish security apparatus on Turkish-Israeli relations. © 2023 Informa UK Limited, trading as Taylor & Francis Group.

    Mitotyping of Random Bred Cats and Pure Breed Cats (turkish Angora and Turkish Van) Using Non-Repetitive Mitochondrial Dna Control Region
    (Elsevier, 2024) Bilgen, Nuket; Guvendi, Mervenur; Sezgin, Efe; Can, Huseyin; Koseoglu, Ahmet Efe; Alak, Sedef Erkunt; Un, Cemal
    The Fertile Crescent appears to be the most plausible region where the domestication of cats commenced through a mutually beneficial relationship between wild cats and early agrarian societies. These domesticated cats then journeyed across the globe mirroring the paths of human migration. An examination of mitochondrial DNA (mtDNA) control region-based mitotyping suggested that a significant majority, exceeding 80%, of globally sampled random-bred and pure-bred cats could be categorized into 12 predominant mitotypes. However, the extent of mitotype diversity within random-bred cats from regions proximate to the Fertile Crescent remains inadequately explored. In light of this we aimed to investigate the mitotype diversity in random bred cats sampled from various regions across Turkey. Additionally, we sought to establish a comparison with the mito-type profiles of locally recognized pure breeds, namely the Turkish Angora and Turkish Van. To unravel their evolutionary narratives, we engaged in comprehensive population genetics analyses at both the individual and mitotype-based levels. Our study encompassed a sample size of 240 specimens, forming the basis for both mitotyping and population genetics scrutiny. Our analysis yielded the identification of nine 'universal' mitotypes (A-J), alongside an 'outlier' mitotype group I. Notably mitotypes A and D emerged as particularly prevalent in contrast to the lesser occurrence mitotypes C, G, and H. With the realm of random bred cats the structure of haplotypes exhibited remarkable diversity presenting distinctions from Turkish Angora and Van breeds. Nucleotide diversity was higher compared to previous reports from Turkey and was one of the highest among reported world cat population estimates. Intriguingly, our investigations did not unveil any pronounced instances of strong selection, population expansions or contractions within any specific population or mitotype. To conclude, our study represents a pioneering effort in uncovering the mitotype profiles and haplotype structures inherent to both random-bred and pure breed cats in Turkey. This endeavor not only broadens our understanding of the feline genetic landscape within the region but also lays the foundation for future inquiries into the evolutionary trajectories and genetic legacies of these feline populations.

    On-Site Measurements of Temperature and Humidity Conditions for the Comparison of Urban and Rural Sub-Spaces of Traditional Settlements: Historical City of Mugla, Turkey
    (Taylor & Francis, 2023) Timur, Barış Ali; Başaran, Tahsin; İpekoğlu, Başak
    One of the significant processes that ensures realistic determination of the energy needs of historical buildings is case-specific definition of their local microclimatic conditions. Accordingly, the aim of this study is to determine differences for the parameters of temperature and humidity in urban and rural sub-settlements of the historical city, Mugla/Turkey. Study method consists of on-site measurements of these variables in sub-settlements for comparisons. As a result, it was identified urban zone shows heat island characteristics with warmer, drier, and more stable conditions; while rural sub-settlement remains cooler, more humid, and more erratic. In parallel, calculated extents of these differences demonstrate the significance and necessity of on-site measurements and consequential microclimatic zoning of historical cities as conservation/planning tools for responding to the thermal needs of architectural heritage. A key application of these processes would be the establishment of local databases of case-specific weather data to be used in thermal simulation assessments.

    Visceral Leishmaniasis Caused by Leishmania Tropica
    (Springer, 2023) Özbilgin, Ahmet; Tunalı, Varol; Çavuş, İbrahim; Vardarlı Tetik, Aslı; Dinç, Melike; Yalçın, Talat; Gündüz, Cumhur; Beyaz, Merve; Köse, Şükran
    PurposeIn Turkey, the main causative agent of visceral leishmaniasis (VL) is Leishmania. infantum and the main causative agent of cutaneous leishmaniasis (CL) is Leishmania tropica. In this study, we aimed to discuss the possible mechanisms, clinical aspects, and threat of visceralizing L. tropica.MethodsThis study includes seven cases of VL caused by L. tropica.Five patients were male (71%) and four were adults (57%).ResultsAll the VL patients complained of fever and splenomegaly. Fatigue, pancytopenia, and hepatomegaly were present in six patients each (86%), while weight loss and gastrointestinal system (GIS) symptoms were present in 5 patients (71%).ConclusionsIn this study, we have evaluated seven cases of visceralized L. tropica (VLT) in the context of the changing leishmaniasis epidemiology in Turkey. We have evaluated the possible mechanisms of visceralization; inter- and intraspecies genetic exchange with all the old world leishmaniasis agents present in the region, stress induced by inappropriate use of drugs, and possible ongoing adaptation mechanisms of Leishmania spp. The threat posed by VLT is significant as L. tropica is the most widespread and most common cause of leishmaniasis in Turkey. We do not know the vectorial capacity of the sand flies for the transmission of VLT strains or if these strains are in circulation in Turkey. Future studies should be carried out to investigate these issues as the transition of L. tropica from a mild disease-causing agent to a mortal one poses a significant public health concern for Turkey and Europe.

    Augmented Reality Technology Adoption: Case of a Mobile Application in Turkey
    (Elsevier, 2021) Yavuz, Merve; Çorbacıoğlu, Eda; Başoğlu, Ahmet Nuri; Daim, Tuğrul U.; Shaygan, Amir
    With the increasing use of smart devices, augmented reality (AR) technology has become widespread in mobile devices. As with user interaction technologies, there are factors affecting the use of applications in mobile augmented reality (MAR) applications. In this study, the factors affecting the use of mobile augmented reality in Turkey are investigated. Although AR and MAR are generally investigated during the research period, “Augment”, the application, was used in the survey and interview parts of the research study. The interview consists of three different parts in addition to a quantitative experimental study. More than hundred variables were obtained from articles and interviews which 22 of them were selected. The results showed that the two most important factors that influence usage of MAR applications are security and privacy. These two are followed by ease of learning, visual quality of the application 3D model, and ease of use in importance, respectively. It is recommended that designers and application developers consider these five variables when designing or developing a MAR application. © 2021 Elsevier Ltd
