Attachment Insecurity and Restrictive Engulfment in College Student Relationships: the Mediating Role of Relationship Satisfaction
(Emerald Publishing Limited, 2018) Hatipoğlu Sümer, Zeynep; Murray, Christine; Toplu Demirtaş, Ezgi
Purpose Studies on restrictive engulfment (RE) – a subtype of psychological aggression in intimate relationships – have focused either on insecure attachment or relationship satisfaction, not both. Therefore, the purpose of this paper is to investigate relationship satisfaction as a potential mediator of the associations between anxious and avoidant attachment and RE perpetration among college students. Design/methodology/approach A sample of 322 college students (178 women, 137 men, and seven other gender-identified) completed the experiences in close relationship inventory, relationship assessment scale, and RE subscale of the multidimensional measure of emotional abuse. Findings Among the sample, 89.3 and 90.5 percent of the college women and men, respectively, reported to have used isolating, restricting, monitoring, and controlling behaviors. The results of structural equation modeling revealed that all direct paths except for that from avoidant attachment to RE were significant. Moreover, significant indirect paths were identified from anxious and avoidant attachment to RE via relationship satisfaction. Research limitations/implications The results of this study should be interpreted with consideration of the study’s limitations. First, the data were drawn from a convenience sample of Turkish college students. Second, the design of the study is correlational; therefore, we cannot assume causality. Finally, this study utilized self-report and retrospective data. Practical implications Though the findings are preliminary, they may inform college counselors and other mental health practitioners about the nature of RE within college students’ dating relationships. College students who are unhappy with their dating relationships but still in those relationships (i.e. they choose not to leave) should be assessed for whether they are the perpetrators and/or recipients of psychological aggression, especially in light of the high rates of this form of aggression in the current and previous studies. Furthermore, assessing psychological dating aggression perpetrators for insecure attachment styles may help mental health professionals who work with college students, envisage the sessions toward areas in the need of improvement, such as their views of themselves and others. Self-esteem, feelings of insecurity and inadequacy in relationships, and dependency can be worked with these clients. Social implications The results of this study also have implications for the prevention of psychological aggression before it occurs. The need for prevention programs is evident in the high rates of psychologically controlling behaviors among college students. It may be useful to implement campus wide programs to raise awareness regarding psychological aggression, such as through events, seminars, posters, flyers, and talks with student groups. Originality/value Despite the limitations of this study, its findings offer insight into the factors that influence the perpetration of psychological aggression within dating relationships among college students. Adult attachment theory offers a useful lens for understanding the possible driving forces behind college students’ controlling behaviors toward their dating partners. In particular, college students who demonstrate an insecure attachment style – and especially an anxious attachment style – combined with low levels of relationship satisfaction appear to be at a high risk for perpetrating RE behaviors.

Bilevel Models on the Competitive Facility Location Problem
(Springer, 2017) Küçükaydın, Hande; Aras, Necati
Facility location and allocation problems have been a major area of research for decades, which has led to a vast and still growing literature. Although there are many variants of these problems, there exist two common features: finding the best locations for one or more facilities and allocating demand points to these facilities. A considerable number of studies assume a monopolistic viewpoint and formulate a mathematical model to optimize an objective function of a single decision maker. In contrast, competitive facility location (CFL) problem is based on the premise that there exist competition in the market among different firms. When one of the competing firms acts as the leader and the other firm, called the follower, reacts to the decision of the leader, a sequential-entry CFL problem is obtained, which gives rise to a Stackelberg type of game between two players. A successful and widely applied framework to formulate this type of CFL problems is bilevel programming (BP). In this chapter, the literature on BP models for CFL problems is reviewed, existing works are categorized with respect to defined criteria, and information is provided for each work.
Fading Boundaries: Insights on Learning "in Between" the Classroom Spaces
(Springer international Publishing Ag, 2021) Soygeniş, Sema Esen; Baloglu, Yasemin Burcu; Baloğlu, Yasemin Burcu; Soygenis, Sema Esen
Along with the advancements in technology and shifts in approaches to education in our day, school architecture began to undergo significant transformations. Learning beyond the classrooms has emerged as a highlighted concern as well as the children's interaction with each other and their environment. Articulation of the changing pedagogical approaches and visions of the innovative, student-centered ideas of the twenty-first century through the physical characters of learning spaces has become a significant issue for research regarding the design of contemporary schools. The evolution of the formation of boundaries, borders, and thresholds defining the distinctions and establishing the relationships and hierarchies between the learning spaces at school settings constitutes a critical part of this process, which deserves attention. This chapter aims to search for boundary-related design suggestions for primary schools in Turkey, based on the data obtained through a field study conducted in Istanbul, which aimed to derive the current issues regarding the spatial use patterns in prototype-based, conventionally designed schools. It is believed that the effective inhabitation of spaces beyond the classrooms has a high potential to contribute to the realization of diverse educational activities and the introduction of more permeable physical and visual boundaries can support the enrichment of school environments.
Anamorphic Projection as a Novel Game Mechanic for Investigating Impossible Spaces in 3D Puzzle Games
(IEEE Computer Society, 2025) Aydındoğan, Irem; Alaçam, Sema
This study introduces a novel game mechanic for 3D puzzle games based on anamorphic projection to explore impossible spaces. By using perspective-driven spatial interactions, the mechanic creates environments that challenge conventional Euclidean logic. Players advance by aligning their viewpoint with distorted projections, making perception a central element of gameplay. A usability test with 33 participants assessed the mechanic's effectiveness through a structured questionnaire focusing on six dimensions: Ease of Control, Goals and Rules, Challenge, Mastery, Curiosity, and Immersion. Results indicate high engagement and cognitive stimulation, especially in mastery and goal clarity. These findings highlight the potential of anamorphic projection to support perceptually rich and mentally engaging puzzle experiences in future game design. © 2025 IEEE.

All You Fear Is Love: the Roles of Rejection by Intimate Others
(Wiley, 2023) Aracı-İyiaydın, Ayşegül; Toplu-Demirtaş, Ezgi; Rohner, Ronald P. P.; Akçabozan-Kayabol, Nazlı Büşra
Interpersonal acceptance-rejection theory (IPARTheory) asserts that recollections of parental rejection in childhood tend to result in psychological maladjustment and intimacy problems in later romantic relationships. Informed by IPARTheory, we investigated the association between maternal & paternal rejection, and fear of intimacy by the mediating role of psychological maladjustment in a Turkish sample with 462 mostly young adults. We further explored the moderator role of gender in Model 1 and the moderating roles of both gender and intimate partner rejection in Model 2. Model 1 revealed that adults who had experienced maternal and paternal rejection in childhood tended to be psychologically maladjusted. Consequently, they also tended to have a fear of intimacy, regardless of gender. Model 2 revealed that women who recall having been rejected in childhood by their mothers tended to be psychologically maladjusted and to have a significant fear of intimacy when they also experienced moderate or more than moderate intimate-partner rejection. However, both women and men who experienced paternal rejection in childhood tended to be psychologically maladjusted and to experience a greater fear of intimacy when they perceived any degree of intimate partner rejection. Implications of the results for theory, research, and practice are discussed.

Turkiye's Water Security Policy: Energy, Agriculture, and Transboundary Issues
(2022) Kibaroğlu, Ayşegül
Water security refers to the availability of adequate quantities and qualities of water for societal needs and resilient ecosystems in the context of current conditions and future global change. Achieving water security is directly linked to food and energy security, protecting and preserving eco systems, and addressing key vulnerabilities and risks from climate change. Good water governance –including transboundary cooperation– is a crit ical feature of any effort to achieve water security. Yet the concept of water security remains abstract and broad. In an attempt to make the concept of water security-relevant in practice, this paper delineates Türkiye’s water se curity policy and practices through institutional and cross-sectoral (energy and food) analysis. Specific attention is paid to Türkiye’s transboundary water security policies.

Development of an Improved Mathematical Model for the Dynamic Response of a Sphere Located at a Viscoelastic Medium Interface
(IOP, 2021) Körük, Hasan
A comprehensive investigation on the static and dynamic responses of a sphere located at elastic and viscoelastic medium interfaces is performed in this study. First, the mathematical models commonly used for predicting the static displacement of a sphere located at an elastic medium interface are presented and their performances are compared. After that, based on the finite element analyses, an accurate mathematical model to predict the static displacement of a sphere located at an elastic medium interface valid for different Poisson's ratios of the medium and small and large sphere displacements is proposed. Then, an improved mathematical model for the dynamic response of a sphere located at a viscoelastic medium interface is developed. In addition to the Young's modulus of the medium and the radius of the sphere, the model takes into account the density, Poisson's ratio and viscosity of the medium, the mass of the sphere and the radiation damping. The effects of the radiation damping, the Young's modulus, density and viscosity of the medium and the density of the sphere on the dynamic response of the sphere located at a viscoelastic medium interface are explored. The developed model can be used to understand the dynamic responses of spherical objects located at viscoelastic medium interfaces in practical applications. Furthermore, the proposed model is a significant tool for graduate students and researchers in the fields of engineering, materials science and physics to gain insight into the dynamic responses of spheres located at viscoelastic medium interfaces.

Optimal Video Length Effect on Flow Experience and Perceived Learning: a Repeated Measure Experimental Design With Randomization
(2024) Demir, Ömer; Birgili, Bengi
Videos are commonly used in education. Benefitting from instructional videos in learning processes empowers students’ academic outcomes. In spite of this, educators have no consensus on optimal video length. There is a need to cease speculations on optimal video length since most of them have been relying only on context-based tips or best practices. Therefore, the purpose of this study is to delve into the optimal video length discussion through the lens of perceived learning and flow experience. We employed repeated measure experimental design with randomization of treatment order for each participant. Twenty-eight university students from two big cities in Türkiye volunteered to participate in the study. Short, medium, and long videos were compared via Friedman test. Results of this study substantiated instructional video length does not seem to affect students’ perceived learning and their overall flow experience. However, they tend to concentrate and focus better on short videos. We call for an end to optimal video length discussion for videos shorter than 10 minutes, especially in terms of learning. The implications relying on the findings were discussed in terms of differences between “thinking to be in flow” and “being actually in flow.” The recommendations are given in detail in the full text.
The Blue Peace: Achieving Peace and Security Through Water Cooperation
(SETA, 2015) Ahmmad, Yadgar; Kibaroğlu, Ayşegül; Vishwanath, Ambika
Water is about people and human security. Unfortunately water has become a source of conflicts around the world, especially in the Middle East. There is a critical need for active water cooper- ation between nations in the region. This article discusses possible ways to achieve such cooperation, using tools developed under the Blue Peace concept. The article highlights a positive example of con- crete steps taken by Turkey and Iraq in the area of track-two hydro diplomacy, which could potentially expand to other countries in the region. Experiences from around the world demonstrate that sustainable active water cooperation is possible and there are many examples that could be adapted by countries in the Middle East.

(TEDMEM, 2016) Son-Turan, Semen
This study presents an innovative and sustainable system formobilizing Turkish university alumni to contribute to acrowdfunded pool repackaged as a student debt instrument withan elaborate performance tracking tool, various payoff structuresand income-contingent repayment schedules. The ultimate aim isto offer a remedy for the conspicuous global shortage ofalternative finance sources and various forms of aid to highereducation students in the short-term, and, through enablingequitable and egalitarian access to quality higher education,transforming society and enhancing economic development in thelonger-term. The model rests upon a six-dimensional frameworkand its infrastructure is facilitated by a newly emerged form ofdigitally enhanced financing, “crowdfunding”. The researchmethod involves content analysis and data triangulation forvalidation purposes to determine the sub-themes surrounding thehigher education problem in Turkey. The theme-driven keywordsare searched for on Turkey’s first original social network, EksiSozluk, to uncover trends and biases towards student loans, debtrepayment and associated concepts. Subsequently, the samekeywords are utilized in a Google Trends search volume analysis,and are finally validated by a focus group discussion. Thetheoretical framework to explain students’ attitudes towardsborrowing and loan repayment and the motivation behind alumniand charitable giving, rests mainly on behavioral economics. TheA-CDSF Model uniquely addresses the higher education financeproblem in Turkey and offers an easily implementable originalsolution for institutions and policy makers.

Urban Politics and the Work and Labour Processes of Architecture: Survey Research With Young Architect-Workers in Turkey
(Middle East Technical University, 2021) Sert, Esra; Aykaç, Gülşah; Zırh, Besim Can
There is a general tendency in architecture to insistently see the work andlabour conditions of architects independently from “the production of nature as urban space” (Sert, 2020) embedded in the neoliberal capitalist economic order. However, considering the socio-ecologically crisisprone environments in which we live, understanding the complicated relationship among nature, the urban, and society becomes more crucial than ever before (Heynen, et al., 2006; Harvey, 1996; Smith, 2008). This article aims to question the common trend that treats the production process of urban space as if it were independent of the working conditions of architects. Current architectural theory struggles to find concepts for guiding the complicated relationship of architectural process particularly working conditions of architects with urbanization of nature in the 21st century. Accordingly, as specialized citizens, architects try to rethink ecological and civic imaginaries (Karvonen, 2011) for understanding human embeddedness in space, time, nature, and place (Harvey, 1996;Gandy, 2006). © 2021,Metu Journal of the Faculty of Architecture.

Fuzzy Optimization for Portfolio Selection Based on Embedding Theorem in Fuzzy Normed Linear Spaces
(De Gruyter, 2014) Solatikia, Farnaz; Kılıç, Erdem; Weber, Gerhard-Wilhelm
In this paper, we propose a novel approach Embedding Theoremabout Menger probabilistic normed Spaces. The main idea behind ourapproach consists of taking advantage of interplays between Mengerprobabilistic normed spaces and normed spaces in a way to get anequivalent stochastic program. This helps avoiding pitfalls due to severe over simplification of the reality. The embedding theorem showsthat the set of all fuzzy numbers can be embedded into a Mengerprobabilistic Banach space. Inspired by this embedding theorem, wepropose a solution concept of fuzzy optimization problem which isobtained by applying the embedding function to the original fuzzyoptimization problem.

Nonlinear Benefit-Cost Optimization-Based Selection of Insulation Material and Window Type: a Case Study in Turkey
(2017) Ağralı, Semra; Uctuğ, Fehmi Görkem
In this study, we maximize the energy savings of a hypothetical household by choosing an optimal insulation material with its optimal thickness and also the optimal window type. We develop a nonlinear mixed integer optimization model that maximizes the net present value of the benefits obtained by insulation over the lifespan of the house. Savings are calculated based on the gains from the electricity usage for air conditioning during cooling-required days and the fuel usage for heaters in heating-required days. The heat transfer calculations consider conductive, convective, and radiative components simultaneously. The optimization model takes the climate conditions of the region where the house is located, the consumer's desired indoor temperature, and the properties of the insulation options; then, it returns a combination of selected insulation materials with its optimum thickness and window type as output. We applied the optimization model developed to hypothetical houses in four different climatic regions of Turkey for different lifespans. For all reasonable lifespans, the model choses stonewool as the ideal insulation material. For high interest rates, single windows or double-glazed windows are preferable, but as the interest rate decreases and the net present value of the energy-savings increases, the model prefers triple-glazed windows as the ideal material. Erzurum, a city in climatic region 4, characterized by very cold winters and cool summers, was found to require the highest optimum insulation thickness, and the economic return resulting from the above-mentioned energy-saving actions was also found to be the highest in the case of Erzurum. In all the regions, the energy-saving investments were found to be feasible via applying the feasibility assessment techniques of net present value and payback period. The model developed in this study is applicable to any household as long as the required input data are available. Published by AIP Publishing.

Can Managers Become Entrepreneurs? a Moderated Mediation Model of Entrepreneurial Intention
(John Wiley and Sons, 2020) Şahin, Faruk; Karadağ, Hande
This study investigates the role of entrepreneurial knowledge on the formation of entrepreneurial intentions in a sample of 190 middle‐level managers by extending the theory of planned behaviour (TPB). Findings indicate that entrepreneurial knowledge has a significant and positive effect on entrepreneurial intention (EI), whereas personal attitude (PA) and personal behavioural control (PBC) mediate the relationship between entrepreneurial knowledge and intention. Findings also indicate that the third construct of TPB, namely social norm, moderates the mediating role of the indirect intention effect of entrepreneurial knowledge through PA and PBC differently. Together, the findings suggest several directions for managers and organizations, as well as policy‐makers, who are responsible for creating more productive and innovative entrepreneurial ventures.

Turkish Version of the Multidimensional Measure of Emotional Abuse: Preliminary Psychometrics in College Students
(Springer, 2018) Hatipoğlu Sümer, Zeynep; Murphy, Christopher M.; Toplu Demirtaş, Ezgi
The aim of the current study was to investigate the basic psychometrics of the Multidimensional Measure of Emotional Abuse (MMEA; Murphy & Hoover, 1999) in a Turkish sample. Two hundred and fifty-four college students participated and completed the Turkish version of the MMEA (MMEA-TR) along with the Physical Assault of Conflict Tactics Scale—Revised, Experiences in Close Relationships Inventory, Relationship Assessment Scale, and Social Desirability Questionnaire. Confirmatory factor analysis supported the four-factor structure of the MMEA-TR for both victimization and perpetration reports. This factor structure was cross-validated with an independent older sample of 328 dating college students for perpetration reports. Satisfactory criterion validity and internal consistency reliability results were obtained as well. Based on the preliminary investigation, the MMEA-TR appears to be a psychometrically sound measure of psychological dating aggression perpetration and victimization among college students in Turkey. The results, limitations, and recommendations for future studies were discussed.

Extracting, Computing, Coordination: What Does a Triphasic Erp Pattern Say About Language Processing?
(Elsevier, 2021) Çakar, Tuna; Eken, Aykut; Cedden, Gülay
The current study aims at contributing to the interpretation of the most prominent language-related ERP effects, N400 and P600, by investigating how neural responses to congruent and incongruent sentence endings vary, when the language processor processes the full array of the lexico-syntactic content in verbs with three affixes in canonical Turkish sentences. The ERP signals in response to three different violation conditions reveal a similar triphasic (P200/N400/P600) pattern resembling in topography and peak amplitude The P200 wave is interpreted as the extraction of meaning from written.form by generating a code which triggers the computation of neuronal ensembles in the distributed LTM (N400). The P600 potential reflects the widely distributed coordination process of activated neuronal patterns of semantic and morphosyntactic cues by connecting the generated subsets of these patterns and adapting them into the current context. It further can be deduced that these ERP components reflect cognitive rather than linguistic processes. © 2021 Informa UK Limited, trading as Taylor & Francis Group.
The Future of Türkiye-NATO Relations in Light of the Strained Transatlantic Dialogue
(Seta Foundation, 2025) Kibaroğlu, Mustafa
This commentary aims to assess the impact of the changing approach of the U.S. under Trump's second administration on transatlantic relations, the future of NATO, its engagement in the war in Ukraine, and the prospects for further expansion toward the east. The paper also aims to shed light on how these developments may affect the future of Türkiye-NATO relations. While Türkiye remains a critical NATO member due to its strategic geography and military capabilities, domestic skepticism towards the Alliance has grown in response to unresolved disputes and perceived double standards. The commentary ultimately underscores that Türkiye’s future in NATO will depend on the Alliance’s ability to reconcile internal divisions, recalibrate its strategic vision, and balance Türkiye’s security concerns with broader transatlantic priorities. © 2025, SETA Foundation.

Base Station-Assisted Cooperative Network Coding for Cellular Systems With Link Constraints
(IEEE, 2022) Arslan, Suayb S.; Pourmandi, Massoud; Haytaoglu, Elif
We consider a novel distributed data storage/caching scenario in a cellular network, where multiple nodes may fail/depart simultaneously To meet reliability, we allow cooperative regeneration of lost nodes with the help of base stations allocated in a set of hierarchical layers1. Due to this layered structure, a symbol download from each base station has a different cost, while the link capacities between the nodes of the cellular system and the base stations are also constrained. Under such a setting, we formulate the fundamental trade-off with closed form expressions between repair bandwidth cost and the storage space per node. Particularly, the minimum storage as well as bandwidth cost points are formulated. Finally, we provide an explicit optimal code construction for the minimum storage regeneration point for a special set of system parameters.
