At that time, the Library operated from a small room on Milli Müdafaa Street with a collection of approximately fifty books donated by the United Nations. Following the appointment ...
A comprehensive assessment of circular water economy strategies through the water-energy-food-ecosystem nexus approach Şipal, Selin; Alp, Emre; Department of Environmental Engineering (2026-6-30) Increasing pressures on freshwater resources due to population growth, changing consumption patterns, land-use change and climate change highlight the need for integrated water management. Conventional water allocation approaches may intensify competition among agricultural, industrial and urban sectors while threatening environmental flows. Therefore, water management alternatives should be evaluated through their impacts on the Water-Energy-Food-Ecosystem (WEFE) Nexus. Circular Water Economy (CWE) strateg...
REFRAMING THE SATIRIST: SOVIET MEMORY ENGINEERING AND THE MAKING OF ARMENIAN NATIONAL IDENTITY (1955–1970) Uysal, Rüveyda Betül; Zorlu Durukan, Şefika Akile; Department of History (2026-7-28) This thesis examines how the image of 19th-century Ottoman Armenian satirist Hagop Baronyan was reinterpreted within the cultural and ideological framework of Soviet Armenia. Baronyan's original writings emerged from the social and political context of the late Ottoman Empire, primarily targeting social hypocrisy, bureaucratic corruption, and social injustice, while Soviet cultural discourse reframed his works through the lens of socialist ideology. Using qualitative historical and discourse analysis, the ...
ENGINEERING BIFUNCTIONAL CONJUGATED POLYMERS: TRIPHENYLAMINE-BASED SYSTEMS FOR ELECTROCHROMIC ENERGY STORAGE IN ASYMMETRIC HYBRID SUPERCAPACITOR DEVICES Keserci, Arya Zelal; Çırpan, Ali; Ünalan, Hüsnü Emrah; Department of Polymer Science and Technology (2026-7-13) Developing conjugated polymers that simultaneously store energy and exhibit electrochromic behavior represents an attractive but challenging goal in materials chemistry. Triphenylamine (TPA) is an ideal scaffold due to its propeller-like geometry, strong hole-transport capability, and highly reversible electrochemical oxidation. This thesis presents six TPA-based conjugated polymers (P1-P6) across two subseries designed to establish systematic structure-property relationships. In the D-π series, the π-bridg...
HOW IS CLIMATE POLICY UNCERTAINTY ASSOCIATED WITH GREEN INNOVATION? EMPIRICAL EVIDENCE FROM OECD COUNTRIES Yılmaz Yanık, Büşra; Voyvoda, Ebru; Department of Science and Technology Policy Studies (2026-7-31) This thesis examines the relationship between climate policy uncertainty (CPU) and green innovation in selected OECD countries over the period 2000–2020. The study is motivated by two contrasting theoretical perspectives in the literature. While Real Options Theory suggests that uncertainty may delay costly and partially irreversible green innovation investments, Growth Options Theory argues that uncertainty may also create incentives for strategic innovation. To examine this relationship, the thesis constr...
EXPLORING EMOTIONAL RESILIENCE: A MULTIPLE CASE STUDY OF EXPERIENCED ENGLISH INSTRUCTORS IN FOUNDATION UNIVERSITY PREPARATORY PROGRAMS IN TÜRKİYE Koç, Şeymanur; Gündüz, Müge; Tezgiden Cakcak, Sebahat Yasemin; Department of English Language Teaching (2026-8-6) Teaching is a demanding emotional practice, and emotional resilience enables teachers to navigate the complex emotional landscape while sustaining their commitment and well-being. This qualitative multiple case study, grounded in the Teacher Resilience Model (Squires et al., 2023), explored the emotional challenges three experienced English instructors encountered, the supportive resources they drew upon, and how meaning-making shaped their conceptualization and trajectories of emotional resilience from ret...
A fractional-calculus approach to grativational-wave memory Kaya, Sercan; Veske, Doğa; Tekin, Bayram; Department of Physics (2026-7-24) In this thesis, we investigate whether fractional calculus, with its intrinsic long-tailed memory and nonlocal features, can provide a viable model for gravitational-wave memory effects. We consider two toy constructions: (i) a fractional modification of the linearized Einstein field equations using a sequential Caputo operator; and (ii) a fractionalized quadrupole formula in which the same operator acts on the source moment. Both constructions yield history-dependent responses with small memory-like offset...
THE EFFECTS OF LATE SIGN LANGUAGE ACQUISITION ON EMOTION EXPRESSION IN THE NARRATIVE RETELLINGS OF DEAF AND HARD-OF- HEARING CHILDREN AND ADULTS Atik, Mehmet Ali; Karadöller Astarlıoğlu, Dilay Zeynep; Department of Psychology (2026-7-28) Emotional development is closely linked to language development for both hearing and deaf children. Late acquisition of sign language has negative consequences for several aspects of language development. We investigated how acquiring sign language late relates to differences in the use of linguistic forms (i.e., overt constructed action, non-overt constructed action, and non-enacting signing) and articulatory channels (i.e., facial expressions, manual gestures, lexical signs, and head/body movements) to ex...
DESIGN, SYNTHESIS, CHARACTERIZATION, AND PHOTOVOLTAIC PERFORMANCE EVALUATION OF NOVEL NON-FULLERENE ACCEPTORS FOR ORGANIC SOLAR CELLS Çalışkan Arslan, Meriç; Çırpan, Ali; Hızalan Özsoy, Gönül; Department of Polymer Science and Technology (2026-7-13) Organic photovoltaics (OPVs) have emerged as a promising renewable energy technology owing to their lightweight nature, mechanical flexibility, low-cost fabrication, and compatibility with large area production. Although the development of non-fullerene acceptors (NFAs) has significantly improved device performance, understanding the relationship between molecular structure and photovoltaic properties remains a key challenge. In this thesis, a core engineering strategy was employed by replacing the conventi...
CONGRUENCE BETWEEN FLOWCAM IMAGING AND MICROSCOPY DEPENDS ON FUNCTIONAL CATEGORİZATION CHOICE IN PHYTOPLANKTON COMMUNITY: CASE STUDY OF SALINIZATION MESOCOSM EXPERIMENT Uyar, Zeynep Dilbe; Beklioğlu, Meryem; Özkan, Korhan; Department of Earth System Science (2026-7-20) Automated imaging platforms such as FlowCam are increasingly used in phytoplankton monitoring, yet whether functional classification frameworks developed for high-magnification microscopy can be reliably applied to automated imaging data remains untested. We evaluated the compatibility of two widely used frameworks, Reynolds Functional Groups (RFG) and Morphology-Based Functional Groups (MBFG), with FlowCam automated imaging, using Utermöhl microscopy as reference. We analysed 47 paired samples from a sali...

Adopting a convergent mixed-methods design and a maximum-variation logic, the study integrated survey data from 83 students, interviews with ten students and two professors, and classroom observations. Quantitative data were analyzed through descriptive statistics, relia...
Processing of Lexical Aspect in Turkish Yıldırım, Hilal; Özge, Duygu; Gracanın Yüksek, Martına; Department of English Language Teaching (2026-7-20) This dissertation investigates the lexical aspectual organization of Turkish verbs and its consequences for sentence processing through two studies. Study 1 used an offline rating task with 64 native speakers to classify 108 Turkish verbs along punctivity, iterativity, and durativity dimensions. Hierarchical Clustering on Principal Components revealed three unequally coherent verb classes as punctive, iterative, and durative. The punctive class showed the strongest boundaries while the iterative was the mos...

CONCEPTUALIZING E-SCOOTER USER BEHAVIOR IN THE CONTEXT OF SUSTAINABLE MOBILITY: DEVELOPING THE ELECTRIC SCOOTER USER BEHAVIOR QUESTIONNAIRE, INVESTIGATING ITS RELATIONSHIP WITH SUSTAINABLE BEHAVIORS AND PERSONALITY Ergin, Uluğhan; Öz, Bahar; Department of Psychology (2026-8-3) The traffic and transportation sector is a major contributor to global climate change, and reducing its impact calls for the sustainable mobility (SM) paradigm. The SM literature has largely concerned itself with transforming systems into more environmentally sound ones, treating people primarily as adopters who decide whether to use a given system. The present study goes further and focuses on the human factor, specifically how individuals behave during e-scooter use, as a determinant of SM. It develops a ...

CAN ENVIRONMENTAL INFORMATION RESHAPE SOCIAL NORMS? AN EXPERIMENTAL STUDY Aslan, Esmanur; Büyükboyacı Hanay, Mürüvvet İlknur; Department of Science and Technology Policy Studies (2026-7-31) We explore whether providing information about the environmental footprint of clothing production can reshape social norms and individual perceptions towards the lifespans of garments. In our study, using an incentivized coordination game, we measure how socially and personally appropriate participants find six different usage durations, ranging from "3-6 months" to "more than 4 years," across a control and a treatment group. Our analysis ultimately reveals two key insights. First, the environmental informa...
