    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 Women's Visceral Engagement With Electric Appliances in Turkish Kitchens
    (Springernature, 2025) Emgin, Bahar; Karaosmanoğlu, Defne; Ata, Leyla Bektaş; Karaosmanoglu, Defne; Ata, Leyla Bektas; Emgin, Bahar
    This paper investigates the narratives and experiences of women regarding cooking with small electric appliances. It intends to offer a novel perspective on gender and technology studies by foregrounding the visceral dimensions of these encounters. Drawing from a larger project on the historical representations and lived experiences of domestic technologies in Turkey, it highlights how the embodied dimensions of cooking shape the ways women perceive, adapt, and integrate technology into their daily lives. This study is based on interviews with twenty-seven women across five cities in Turkey conducted between 2022 and 2024. While small electric appliances are often marketed for convenience and efficiency, we argue that focusing solely on their instrumental benefits neglects the complex and visceral ways women engage with technology. A visceral approach remains an undervalued lens for understanding these interactions, particularly as women's embodied knowledge and relationships to kitchen appliances challenge scholarship that prioritizes progress and efficiency. As active agents, many women resist these technologies, viewing them as misaligned with the embodied knowledge and practices integral to cooking. By reevaluating the relationship between food, gender, and technology, we propose that such disengagement challenges the positivist reliance on science and technology, emphasizing the importance of embodied knowledge and everyday practices in shaping women's interactions with technology.

    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

    Convenient Site Selection of a Floating Pv Power Plant in Türkiye by Using Gis-Fuzzy Analytical Hierarchy Process
    (Springer Heidelberg, 2024) Karipoglu, Fatih; Koca, Kemal; Ilbahar, Esra
    Floating photovoltaics (FPVs) are appearing as a promising and an alternative renewable energy opinion in which PV panels are mounted on floating platforms in order to produce electricity from renewable energy on water such as seas, dams, rivers, oceans, canals, fish farms, and reservoirs. So far, such studies related to the body knowledge on financial, technical, and environmental aspects of installation of FPV have not been performed in Turkey while expanding steadily in other countries. In this study, suitable site selection for installation of FPV power plants on three lakes in Turkey was studied by performing geographic information system (GIS) and the fuzzy analytic hierarchy process (FAHP) as multi-criteria decision-making (MCDM) method. This detailed study revealed that the criterion of global horizontal irradiance (GHI) was determined as the most crucial criterion for the installation of FPV on Beysehir Lake, Lake of Tuz, and Van Lake. Additionally, it was clearly seen that the Beysehir Lake had the highest value approximately 52% among other lakes for installation, that is why Beysehir Lake is selected as the best option for installation of an FPV system with this multi-criteria approach.

    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.

    Urban Earthquake Vulnerability Assessment and Mapping at the Microscale Based on the Catastrophe Progression Method
    (SPRINGER, 2023) Gerçek, Deniz; Güven, İsmail Talih
    Vulnerability assessment and mapping play a crucial role in disaster risk reduction and planning for adaptation to a future earthquake. Turkey is one of the most at-risk countries for earthquake disasters worldwide. Therefore, it is imperative to develop effective earthquake vulnerability assessment and mapping at practically relevant scales. In this study, a holistic earthquake vulnerability index that addresses the multidimensional nature of earthquake vulnerability was constructed. With the aim of representing the vulnerability as a continuum across space, buildings were set as the smallest unit of analysis. The study area is in Izmit City of Turkey, with the exposed human and structural elements falling inside the most hazardous zone of seismicity. The index was represented by the building vulnerability, socioeconomic vulnerability, and vulnerability of the built environment. To minimize the subjectivity and uncertainty that the vulnerability indices based on expert knowledge are suffering from, an extension of the catastrophe progression method for the objective weighing of indicators was proposed. Earthquake vulnerability index and components were mapped, a local spatial autocorrelation metric was employed where the hotspot maps demarcated the earthquake vulnerability, and the study quantitatively revealed an estimate of people at risk. With its objectivity and straightforward implementation, the method can aid decision support for disaster risk reduction and emergency management.

    A Review of the Geothermal System Evolution and Distribution in the Central Anatolian Crystalline Complex (türkiye)
    (TUBITAK, 2023) Şener, M.F.; Öztürk, M.Z.; Baba, A.
    Türkiye is located in the Mediterranean sector of the Alpine–Himalayan tectonic belt and is among the foremost seven countries in the world having an abundance of geothermal resources. The Central Anatolian Crystalline Complex (CACC) is one of the most important geothermal regions in Türkiye. This study aims to evaluate the geothermal system of CACC using the geological, structural, and hydrogeochemical properties that were obtained from previous studies. The present study investigated and evaluated the hydrogeochemical and isotopic properties of 762 water samples belonging to 45 different localities from 41 scientific studies. The result shows that CACC has different heat sources and different hydrogeochemical processes. Major element chemistry of the water reveals that the geothermal fluids are mostly of the Ca-Mg-HCO3, Na-Cl-HCO3, and Ca-Cl water types. Silica geothermometers suggest that the reservoir temperature ranges from 48 to 180 °C. Based on the δ18O-δD relationship, water samples have a high-altitude meteoric origin. Stable isotopic data indicate that the geothermal fluids are formed by local recharge and deep circulation of meteoric waters. © TÜBİTAK.

    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.
