High school and university students' reasoning about decision-making autonomy and parental authority legitimacy in child–mother conflicts
(WILEY, 2025-05-02) Kuyel, Nilay; Acar, Melike
This study investigated youths' reasoning about personal autonomy and maternal authority in hypothetical emerging adult child–mother conflicts in Türkiye. High school and university students (N = 138, Mage = 19.72 years) from secular and religious schools completed a self-report questionnaire including eight conflict scenarios where the mother opposes her child's decision to marry a non-Muslim or get a tattoo. Maternal opposition in hypothetical scenarios was presented in the forms of maternal advice and maternal use of haram opposition. Haram opposition implies the declaration of maternal accrued rights (a concept deeply rooted in Turkish culture) as haram. The results showed that participants were more likely to subordinate child autonomy to maternal authority when the mother in hypothetical scenarios was depicted as using haram opposition. Authoritative parenting appeared to strengthen this effect. This study has shown that haram opposition is a psychological control mechanism to subordinate child autonomy to maternal authority.
The Moderation Role of Supervisor Support in the Interaction of Illegitimate Task, Emotional Exhaustion, and Self-Undermining: a Job-Demand Resources Approach
(Sage Publications Ltd, 2025) Konuk, Hızır; Küçük, Burcu Aydın
The study aims to reveal both the direct and indirect association between Illegitimate Tasks and Self-Undermining behavior through Emotional Exhaustion, with a focus on the moderating role of Supervisor support. It also seeks to highlight the conditions under which Supervisor support provides positive organizational outcomes. A survey was applied to 978 white-collar participants working in SMEs in Turkey. The Job-Demand Resources framework served as the theoretical basis for the research. Results indicated that Illegitimate Tasks are associated with self-undermining, with emotional exhaustion partially mediating this relationship. Supervisor support was found to have a negative relationship with emotional exhaustion and self-undermining; however, its moderating role was positive rather than negative. Supervisor support increased the effect of illegitimate tasks on emotional exhaustion and self-undermining, contradicting the expected buffering effect. The study contributes to the literature by offering evidence on when supervisor support becomes dysfunctional for organizations.
Effect of Reinforcement Amount on the Microstructural and Mechanical Properties of Mechanically Alloyed Graphene Nanoplatelet Reinforced Al-3.5 Wt% Cu Composites
(Elsevier Science, 2025) Mertdinç-Ülküseven, Sıddıka; Süzer, İlayda; Ürper, Ahmet Kasım; Çelik, Alper İbrahim; Bacı, Doruk Tuncer; Gürarslan, Kerem Alper; Ağaoğulları, Duygu; Öveçoğlu, M. Lütfi
In this study, various amounts (0.25, 0.5, 0.75, 1, and 2 wt%.) of graphene nanoplatelets (GNPs) reinforced Al-3.5 wt% Cu metal matrix composites were produced using powder metallurgy processes consisted mechanical alloying and pressureless sintering. To compare the properties of the sintered composites, as-blended and 4 h mechanically alloyed powders were sintered to yield Al-3.5 wt% Cu matrix alloys. The microstructural, thermal and mechanical properties were examined using relevant characterization techniques. The formation of Al2Cu phase was detected at all XRD patterns of the sintered samples other than matrix and reinforcement phases. Mechanically alloyed powders exhibit the equiaxed particle morphology compared to the as-blended ones, their mechanical properties were found better than as-blended and sintered samples. Additionally, mechanical alloying led to the dispersion of GNP reinforcements into the AlCu matrix. The highest hardness value (around 153 HV) was obtained for 2 wt% GNP reinforced composite. The highest wear resistance was recorded for 1 wt% GNP reinforced composite with 2.07 +/- 0.2 mm(3)/N.mx10(-3) wear rate. Additionally, composites' compressive strength improved with adding 1 wt% GNP (similar to 68.5 MPa). The good dispersion of the optimum amount of GNP's via mechanical alloying provide to obtain preferable mechanical properties.
Determining the Effect of Video Information on the Dental Anxiety Levels of the Endodontic Patients: a Randomised Clinical Trial
(Wiley, 2025) Anatürk, Şule; Dönmez Özkan, Hicran; Saral, İlkim Pınar; Çakar, Tuna
Objective The present study assessed the effectiveness of pretreatment education in the form of Visual Video Information (VVI) on the anxiety levels of patients during endodontic treatment steps. Methods Patients (n = 120) having single-rooted teeth with a single root canal diagnosed with asymptomatic irreversible pulpitis and/or pre-prosthetic root canal treatment were included in this study. After completing anxiety scales and a sociodemographic/dental habits survey, the patients were randomly divided into two groups. Just before the endodontic treatment, VVI was given to the video group patients, while the control group patients received routine information verbally. In both groups, a galvanic skin response (GSR) device was placed on the patients' wrists to record the stress levels during the endodontic treatment process. Anxiety scales and a feedback-satisfaction survey were administered to all patients after the treatment process. Then, statistical analysis was performed (alpha = 0.05). Results This study performed 60 endodontic treatments on 60 patients (30 females and 30 males). Sociodemographic characteristics and dental treatment habits of the patients significantly affected dental anxiety scale scores (p < 0.05). VVI resulted in a significant decrease in the mean scores of anxiety before and after the treatment, but this decrease was not significant between the groups (p > 0.05). Similarly, VVI did not impact the GSR readings between the groups during treatment (p > 0.05). Conclusions The educational VVI is effective for reducing anxiety in patients undergoing endodontic treatment. In addition, the electrodermal activity method is a promising alternative for objectively assessing anxiety levels.
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 T & uuml;rkiye-NATO relations. While T & uuml;rkiye 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 T & uuml;rkiye's future in NATO will depend on the Alliances' ability to reconcile internal divisions, recalibrate its strategic vision, and balance T & uuml;rkiye's security concerns with broader transatlantic priorities.
Examining the Role of Dark and Light Triad Traits on Sociosexuality
(Routledge Journals, Taylor & Francis Ltd, 2025) Urganci, Betul; Sevi, Baris; Dogruyol, Burak; Sakman, Ezgi
Sociosexual orientation-the tendency toward casual sex, is associated with dispositional components of personality such as higher scores of Dark Triad traits (narcissism, Machiavellianism, and psychopathy). Yet, it remains unknown which specific Dark Triad traits and Light Triad traits (Kantianism, Humanism, and Faith in Humanity) predict sociosexuality and its dimensions while controlling for the others. In the current study, using an online community sample (N = 308), we examined the links between Dark Triad traits, Light Triad traits, overall sociosexuality, and sociosexuality dimensions (attitude, behavior, desire). Using hierarchical regression, we found that only psychopathy emerged as the predictor of behavior, desire, attitude dimensions, and sociosexuality total score. This effect held when controlling for age, sex, relationship status, the other two Dark personality traits, and the Light Triad. Results suggest that individuals high on psychopathy have a greater tendency toward uncommitted relationships.
A Preliminary Study on the Role of Personal History of Infectious and Parasitic Diseases on Self-Reported Health Across Countries
(W B Saunders Co Ltd, 2025) Pfuhl, Gerit; Prazeres, Filipe; Kowal, Marta; Aavik, Toivo; Abad-Villaverde, Beatriz; Afhami, Reza; Sorokowski, Piotr; Toplu-Demirtaş, Ezgi
Objectives: Infectious diseases are often associated with decline in quality of life. The aim of this study is to analyze the relationship between personal history of communicable, i.e., infectious and parasitic diseases and self-rated health. Study design: Secondary analysis of a large dataset multi-country observational study. Methods: We used a four-pronged analysis approach to investigate whether personal history of infectious and parasitic diseases is related to self-reported health, measured with a single item. Results: Three of the four analyses found a small positive effect on self-reported health among those reporting a history of pathogen exposure. The meta-analysis found no support but large heterogeneity that was not reduced by two classifications of countries. Conclusion: Personal history of infectious and parasitic diseases does not reduce self-reported health across a global sample.
The Ill Fortune of Attachment Insecurity and Dyadic Distrust in Marital Satisfaction: a Dyadic Perspective in Turkish Couples
(Springernature, 2025) Cetinkaya Yildiz, Evrim; Araci Iyiaydin, Ayseguel; Toplu Demirtas, Ezgi
Objective: The objective of the current study is to explore the actor, partner and mediating effects of dyadic trust in the relationship between insecure romantic attachment and marital satisfaction in a Turkish sample of heterosexual married couples.BackgroundAlthough the vital role of dyadic trust in a romantic relationship has been recognized for many years, the mediating role of dyadic trust in the relationship between insecure attachment and marital satisfaction has not been explored much in previous research.MethodThe sample comprised 174 married couples living in suburban areas in the central Anatolian region of T & uuml;rkiye. Couples were recruited through personal networks and online mailing lists of local governmental institutions. Two Actor-Partner Interdependence Mediation Model analyses were carried out to estimate mediation with dyadic data using MEDYAD.ResultsThe actor effects between insecure romantic attachment and marital satisfaction were found to be mediated by dyadic distrust. Moreover, two partner mediating effects were found significant. Husbands' anxious attachment predicted wives' dyadic distrust, which in turn predicted wives' marital dissatisfaction. Likewise, husbands' anxious attachment also predicted their own dyadic distrust, which in turn predicted their wives' marital dissatisfaction.ConclusionThe findings show that for insecurely attached individuals, dyadic trust has an important role in marital satisfaction and thus should be the central topic in couple counseling.
Improving Facial Emotion Recognition Through Dataset Merging and Balanced Training Strategies
(Pergamon-Elsevier Science Ltd, 2025) Kirbiz, Serap
In this paper, a deep learning framework is proposed for automatic facial emotion based on deep convolutional networks. In order to increase the generalization ability and the robustness of the method, the dataset size is increased by merging three publicly available facial emotion datasets: CK+, FER+ and KDEF. Despite the increase in dataset size, the minority classes still suffer from insufficient number of training samples, leading to data imbalance. The data imbalance problem is minimized by online and offline augmentation techniques and random weighted sampling. Experimental results demonstrate that the proposed method can recognize the seven basic emotions with 82% accuracy. The results demonstrate the effectiveness of the proposed approach in tackling the challenges of data imbalance and improving classification performance in facial emotion recognition.
Global Profiles of Positive Youth Development: a Person-Oriented Analysis Among Emerging Adults Living in 21 Countries
(Springer/Plenum Publishers, 2025) Buenconsejo, Jet Uy; Ferrer-Wreder, Laura; Dimitrova, Radosveta; Pavlova, Iuliia; Bosnar, Ksenija; Bartoluci, Suncica; Altansukh, Suvdanchimeg; Karakulak, Arzu
Although global research on the 5Cs model of Positive Youth Development (PYD; competence, confidence, connection, character, and caring) has expanded in recent years, there is a lack of understanding about distinct and consistent PYD profiles across youth from diverse socio-cultural contexts. To address this gap, this study utilized a person-oriented analytic approach to examine the PYD profiles of 11,481 emerging adults (Mage = 21.77; SDage = 2.74; 68.66% females) from 21 countries in four continents. Results of the multi-group latent profile analysis revealed four consistent profiles of PYD across countries: high/balanced (41%), self-efficacious (28%), socio-emotional (20%), and low/self-centered (11%). Participants' age, gender, educational attainment, and country-level collectivism were also found to be associated with specific profiles. Older and more-educated females from less collectivistic countries were more likely to be in a high/balanced profile, while younger males from more collectivistic countries tend to be in a low/self-centered profile. Older and more-educated males from less collectivistic countries were more likely to be in a self-efficacious profile, while younger and less-educated females from more collectivistic countries tend to be in a socio-emotional profile. Controlling these socio-contextual covariates, the four profiles exhibited distinct relations with adaptive (resilience and contribution) and maladaptive outcomes (anxiety and adverse life experiences) during the COVID-19 pandemic. The results highlight the importance of fostering a balanced set of Cs, which include both self-efficacious and socio-emotional qualities, to promote positive adaptation in challenging times across diverse developmental settings.
A Machine Learning Approach To Resolving Conflicts in Physical Human-Robot Interaction
(Association for Computing Machinery, 2025) Ulas Dincer, Enes; Al-Saadi, Zaid; Hamad, Y.M.; Aydın, Yusuf; Kucukyilmaz, A.; Basdogan, C.
As artificial intelligence techniques become more sophisticated, we anticipate that robots collaborating with humans will develop their own intentions, leading to potential conflicts in interaction. This development calls for advanced conflict resolution strategies in physical human-robot interaction (pHRI), a key focus of our research. We use a machine learning (ML) classifier to detect conflicts during co-manipulation tasks to adapt the robot's behavior accordingly using an admittance controller. In our approach, we focus on two groups of interactions, namely "harmonious"and "conflicting,"corresponding respectively to the cases of the human and the robot working in harmony to transport an object when they aim for the same target, and human and robot are in conflict when human changes the manipulation plan, e.g. due to a change in the direction of movement or parking location of the object.Co-manipulation scenarios were designed to investigate the efficacy of the proposed ML approach, involving 20 participants. Task performance achieved by the ML approach was compared against three alternative approaches: (a) a rule-based (RB) Approach, where interaction behaviors were rule-derived from statistical distributions of haptic features; (b) an unyielding robot that is proactive during harmonious interactions but does not resolve conflicts otherwise, and (c) a passive robot which always follows the human partner. This mode of cooperation is known as "hand guidance"in pHRI literature and is frequently used in industrial settings for so-called "teaching"a trajectory to a collaborative robot.The results show that the proposed ML approach is superior to the others in task performance. However, a detailed questionnaire administered after the experiments, which contains several metrics, covering a spectrum of dimensions to measure the subjective opinion of the participants, reveals that the most preferred mode of interaction with the robot is surprisingly passive. This preference indicates a strong inclination toward an interaction mode that gives more control to humans and offers less demanding interaction, even if it is not the most efficient in task performance. Hence, there is a clear trade-off between task performance and the preferred mode of interaction of humans with a robot, and a well-balanced approach is necessary for designing effective pHRI systems in the future. © 2025 Copyright held by the owner/author(s).
Qubo Formulations and Characterization of Penalty Parameters for the Multi-Knapsack Problem
(IEEE-Inst Electrical Electronics Engineers Inc, 2025) Guney, Evren; Ehrenthal, Joachim; Hanne, Thomas
The Multi-Knapsack Problem (MKP) is a fundamental challenge in operations research and combinatorial optimization. Quantum computing introduces new possibilities for solving MKP using Quadratic Unconstrained Binary Optimization (QUBO) models. However, a key challenge in QUBO formulations is the selection of penalty parameters, which directly influence solution feasibility and algorithm performance. In this work, we develop QUBO formulations for two MKP variants-the Multidimensional Knapsack Problem (MDKP) and the Multiple Knapsack Problem (MUKP)-and provide an algebraic characterization of their penalty parameters. We systematically evaluate their impact through quantum simulation experiments and compare the performance of the two leading quantum optimization approaches: Quantum Approximate Optimization Algorithm (QAOA) and quantum annealing, alongside a state-of-the-art classical solver. Our results indicate that while classical solvers remain superior, careful tuning of penalty parameters has a strong impact on quantum optimization outcomes. QAOA is highly sensitive to parameter choices, whereas quantum annealing produces more stable results on small to mid-sized instances. Further, our results reveal that MDKP instances can maintain feasibility at penalty values below theoretical bounds, while MUKP instances show greater sensitivity to penalty reductions. Finally, we outline directions for future research in solving MKP, including adaptive penalty parameter tuning, hybrid quantum-classical approaches, and practical optimization strategies for QAOA, as well as real-hardware evaluations.
Room-Temperature Synthesis of Refractory Borides: a Case Study on Mechanochemistry and Characterization of Mo-Borides and W-Borides
(Elsevier Sci Ltd, 2025) Süzer, İlayda; Akbari, Amir; Kaya, Faruk; Mertdinç Ülküseven, Sıddıka; Derin, Bora; Öveçoğlu, M. Lütfi; Ağaoğulları, Duygu
Mo-boride and W-boride powders were produced from native boron oxide, magnesium, and related metal oxide starting materials by mechanochemical synthesis (MCS) followed by an purification treatment. The reaction formation mechanisms and the products were predicted with the FactSageTM thermochemical simulation program. Different conditions were tested to determine the optimum synthesis parameters. MCS was conducted at stoichiometric ratios and different milling durations, using excess reactant amounts over the determined optimum time. After MCS, unwanted phases were removed by HCl acid leaching. Detailed phase analyses of the final powders were obtained by X-ray diffractometer (XRD), whereas detailed microstructure characterization was conducted by scanning electron microscope/energy dispersion spectrometer (SEM/EDS), transmission electron microscope (TEM) and particle size analyzer. Among the utilized parameters, the ideal composition chosen for Mo boride synthesis was 6 h milled and leached MoO3-100 wt% B2O3-50 wt% Mg (1.41 mu m), including alpha-MoB, beta-MoB, MoB2, Mo2B, Mo2B5, and Mo phases. For the synthesis of W boride, the proper composition was found as WO3-100 wt% B2O3-50 wt% Mg (0.37 mu m) containing W2B5, WB, beta-WB, WB4, W2B, and W phases after milling for 20 h and leaching. Besides, as a result of the oxidation resistance measurements at 700 and 800 degrees C, phases belonging to MoO2 and WO2 were found along with boride phases.

Reconnaissance and Discussion on Ground Motion Induced by the 2023 Türkiye-Syria Earthquake
(Taylor and Francis Ltd., 2025) Towhata, I.; Çağlayan, P.Ö.; Tönük, G.; Erginağ, U.C.; Sendir Torisu, S.
This paper discusses the output from the damage reconnaissance conducted after the 2023 Türkiye-Syria earthquake. First, a large landslide occurred in a limestone gentle slope without much ground water. Second, the ground subsidence in the coastal area does not comply the the local soil conditions and other observed post-seismic situations. Third, the acceleration records exhibit stronger motion with longer period and shorter duration towards the western end of the causative fault and suggest supershear rupture. To understand these features of the ground motion, this paper proposes a hypothetical model that can reproduce these observations to a good extent. © 2025 Taylor & Francis Group, LLC.
Unemployment Polarisation and Club Convergence in Türkiye
(Wiley, 2025) Karahasan, Burhan Can
Turkish economy has undergone massive transformation during the 2000s. Annual economic growth reached a peak of 10% in the early 2000s. However, the side effects of global financial crises and the internal macroeconomic imbalances shift the growth trajectory of T & uuml;rkiye into a new path of unstable economic growth. While macroeconomic consequences are densely discussed we know less about the adjustment of local labour markets. To fill this gap, we examine the club formation of Turkish regions by analysing their unemployment trajectories during the post 2000s. Our findings show that despite rapid economic growth Turkish regions get extremely polarised and form distinct convergence clubs. Remarkably polarisation is higher for the female population. Geographically, polarisation is in the form of an isolation for the least developed south-eastern regions and some of the developed urbanised western regions. Additionally, our robustness exercises indicate higher polarisation after 2013 as Turkish economic growth starts to become more volatile and less sustainable. Finally, our spatial extensions show that impact of spatial proximity has significant influence on the accurate extent of unemployment deprivation.
Selimiye as a Commemorative Monument in Modern Turkey
(Routledge Journals, Taylor & Francis Ltd, 2025) Sezgin, Ahmet
Selimiye, an Ottoman dynastic mosque, became a contested site of memory in the 20th century. As the Ottoman Empire disintegrated, Bulgaria, Greece, and Turkey all had ambitions and even temporary control over Edirne during the first decades of the 20th century. Its unique location at the crossroads of nation-states provides fertile ground for investigating the role of architectural heritage in the formation of a nation's collective memory, with a consideration of transnational influences. This article investigates the development and reception of commemorations involving the monument through close readings of newspaper reports from Greece, Turkey, and Bulgaria, as well as international media. It reveals the transnational dimension in forming a national frame of remembrance for the liberation of Edirne.
Sociosexuality Is Associated With Disease Avoidance Tendencies and Can Decrease During a Real-Life Disease Threat
(Springer, 2024) Sevi, Baris; Shook, Natalie J.
Engaging in uncommitted sexual relationships increases the risk of pathogen transmission through close contact with novel partners. As such, greater disease avoidance tendencies may be associated with lower sociosexuality. Across three studies, we examined this proposition. In Studies 1a and 1b, we cross-sectionally assessed the associations between individual differences in disease avoidance (i.e., germ aversion, perceived infectability) and sociosexuality dimensions (i.e., behavior, attitude, desire). Greater germ aversion was significantly associated with more restricted sociosexuality across all three dimensions and replicated in both samples. Perceived infectibility was associated with more unrestricted sociosexual attitude and desire, but only in Study 1a. In Study 2, we tested whether sociosexuality levels changed with the COVID-19 pandemic. Participants reported more restricted sociosexuality levels during the COVID-19 pandemic compared to pre-pandemic levels, where a decrease was especially seen in sociosexual desire. Further, this decrease in sociosexual desire was predicted by pre-pandemic germ aversion levels. Overall, the findings indicate that disease avoidance tendencies (i.e., germ aversion) and real-life disease threat are associated with lower tendency to engage in uncommitted sexual relationships. Further research is needed to understand the causal relation of these two constructs, which may help in developing interventions and campaigns to support better sexual health.

Populism and Income Inequality: Is Income Inequality in Türkiye a Political Choice?
(Istanbul Univ, 2024) Asfuroğlu, Dila
The argument that national inequalities are political and thereby driven by political decisions implies that income distribution is not merely an economic phenomenon but also a political one. Hence, this study explores the impact of populist governance on income inequality in T & uuml;rkiye. In doing so, this study addresses whether income inequality in T & uuml;rkiye is a political choice, drawing on economic, social, and political data over the years 20082022. According to the results of the quantitative analysis, the share of income for the working class has fallen, the income gap between the lowest and highest deciles of the working class has narrowed, and the potential for fiscal interventions to reduce income inequality is not realised. In return, the income inequality that existed in 2008 has persisted at the same magnitude over the years. In other words, even if income inequality is not an explicit political choice, the populist governance in T & uuml;rkiye between 2008 and 2022 has chosen not to contribute to the solution to this prevailing inequality.
