(Springer Heidelberg, 2025) Umay, Ebru; Tanigor, Goksel; Toraman, Fusun; Karaahmet, Ozgur; Bilgilisoy, Meral; Sertpoyraz, Filiz; Nazli, Fatma; 01. Atılım University
Background and aim:Neuromuscular diseases (NMDs) are a heterogeneous group of diseases including motor neurone diseases (MND), muscle diseases (MD), neuropathies and neuromuscular junction diseases (NMJD). NMDs are characterized by a wide range of symptoms and findings, depending on different underlying issues. Therefore, the literature includes specific management and/or rehabilitation recommendations for each subgroup and even for some diseases within these subgroups. Currently, neither in our country nor globally is there a comprehensive recommendation study that thoroughly addresses all aspects of NMD rehabilitation developed by experienced and specialized multidisciplinary experts in the field.Materials and methodsThe recommendations in this paper have been created by a multidisciplinary team for all patients without age limitation under the headings of peripheral neuropathy/polyneuropathy, MND, MD and NMJD using the seven-step and 3 round modified Delphi method via e-mail. The strength of agreements (SOA) was calculated for each item (recommendation) using percentages (response of between 8 and 10%), median values, and interquartile range with Kappa method.ResultsThe opinions of the experts were analysed according to the 3-round modified Delphi method, and a list of 110 items of recommendations for patients with NMDs of all ages was prepared in as much detail as possible to shed light on almost all questions and problems that may be encountered in clinical practice. There were 5 recommendations in the general management subsection, 20 recommendations in the rehabilitation indications subsection, 8 recommendations in the rehabilitation contraindications section, and 77 recommendations in the rehabilitation section (general principles 7 recommendations, modalities 13 recommendations, exercise characteristics 57 recommendations).ConclusionWe think that this study will be a light for physicians dealing with this patient group in clinical practice, as it includes fine details up to exercise prescriptions.

(Wiley, 2025) Pamuk, Erim; Beharry, Avinash; Lambercy, Karma; Dalla-Vale, Margaux; Wahler, Nina; Hosal, Sefik; Simon, Christian; 08. Medical School; 01. Atılım University; Surgical Sciences
Objective: To compare functional and oncologic outcomes in elderly (>= 70 years) and nonelderly (< 70 years) patients after transoral robotic surgery (TORS). Methods: A retrospective chart review was conducted on 114 patients who underwent TORS for head and neck squamous cell carcinoma between 2012 and 2022. Patient and tumor characteristics, perioperative details, complications, and survival parameters were analyzed. Swallowing function was assessed using the Functional Outcome Swallowing Scale (FOSS). Results: Of the 114 patients, 37 (32.5%) were elderly, and 77 (67.5%) were nonelderly. Elderly patients had higher comorbidity scores (p < 0.001). Oropharyngeal and oral cavity primaries were more common in the nonelderly group, whereas laryngeal primaries predominated in elderly patients (p < 0.01). Complication rates were higher in nonelderly (37.6%) than in elderly (18.9%) patients, though not statistically significant (p = 0.07). In elderly patients, FOSS scores showed no significant change preoperatively, postoperatively (< 3 months), or at the last follow-up (median 36 months). The nonelderly group experienced worse early postoperative FOSS scores compared to baseline but showed significant improvement, returning to preoperative levels by the last follow-up. Nonelderly patients had better FOSS scores at last follow-up compared to elderly patients (p = 0.014). Overall and recurrence-free survival outcomes were better in the nonelderly group, but disease-specific survival rates were comparable. Conclusion: Despite higher comorbidity rates in the elderly, TORS demonstrated favorable complication rates in the elderly population. Swallowing function returned to baseline after 3 months in both groups. TORS appears safe for elderly patients with comparable oncologic outcomes.
Right Renal Ectopia Following Major Weight Loss
(BMJ Publishing Group, 2025) Abdulrasool, Amjed Safaa; Noack, Morten Westergaard; Overgaard, Ellen Kristine; Abdulrasool, Mujtaba; 01. Atılım University
Presenting with severe stomach pain from sigmoid volvulus, a woman in her 90s was effectively treated with colonoscopic desufflation. Interestingly, serial imaging over 16 years demonstrated gradual cranial displacement of the right kidney to the hepato-diaphragmatic space without prior trauma, surgery or congenital abnormalities. The patient remained asymptomatic with respect to renal function despite significant anatomical displacement. No specific intervention was required for the ectopic kidney. It is important to recognise the potential for organ migration associated with ageing, significant weight loss or metabolic alterations, particularly in the context of increasing use of weight-loss medications. Awareness of such anatomical variants can prevent misinterpretation of incidental findings on clinically indicated imaging. Routine imaging solely to detect asymptomatic positional changes is not justified.
The "Trickle-Across" Phenomenon: Consumption-Mimicking in Emerging Markets in a Stress Environment
(Emerald Group Publishing Ltd, 2025) Gungordu Belbag, Aybegum; Deligonul, Seyda Z.; Uner, Mehmet Mithat; Cavusgil, S. Tamer; 01. Atılım University; 05. School of Business; Business; Tourism Management
Purpose - This study conceptualizes a novel framework called the "trickle-across" phenomenon to understand how middle-class consumers in emerging markets adapt their consumer behavior during economic crises. Unlike the trickle-down model based on upward emulation, the study explores how risk and uncertainty drive consumers to mimic their in-group. Design/methodology/approach - The study employs a conceptual review approach, synthesizing the crisis literature on middle-class consumer behavior across emerging markets. It offers four novel propositions to explain the socio-psychological underpinnings of the shift in middle-class consumer behavior. Findings - Under normal, low-anxiety conditions, middle-class consumers seek upward mobility through aspirational consumption and class emulation, referred to as trickle-down theory. However, during crises, heightened risk anxiety triggers a shift from upward emulation to lateral mimicry, where individuals conform to the consumption norms of their immediate social cohort. Socio-cultural influences play a critical role in risk trivialization and adapting to economic hardships. Originality/value - The study proposes the trickle-across phenomenon as a defining pattern of middle-class consumer behavior in emerging markets during crises. It shifts the focus from aspirational models to cohort-based survival strategies and highlights how socio-cultural factors help middle-class consumers adapt to economic hardships and preserve identity. The framework provides new insights for marketers, policymakers, and scholars.
AdS3 Black Holes with Primary Proca Hair from a Regularized Gauss-Bonnet Coupling
(Amer Physical Soc, 2025) Alkac, Gokhan; Mesta, Murat; Unal, Gonul; Electrical-Electronics Engineering; 06. School Of Engineering; 01. Atılım University
We construct a consistent three-dimensional Einstein-Gauss-Bonnet theory as a vector-tensor theory within the generalized Proca class by employing a regularization procedure based on the Weyl geometry, which was introduced recently by Charmousis, Fernandes, and Hassaine [Phys. Rev. D 111, 124008 (2025).]. We then obtain an asymptotically Anti-de Sitter (AdS3), static, and circularly symmetric black hole solution with primary Proca hair. Afterward, we investigate the effect of the scalar-tensor GaussBonnet coupling constructed previously by different regularization schemes. We further generalize these solutions by incorporating an electric charge. As special cases, we find a regular black hole solution in addition to charged and uncharged stealth Banados-Teitelboim-Zanelli black hole solutions.
Sustainable Stabilization of Expansive Soils Using Waste Marble Powder and Expanded Polystyrene Beads: Experimental Evaluation and Predictive Modelling
(Elsevier, 2026) Akis, Ebru; Citak, Mete; Lotfi, Bahram; Civil Engineering; 06. School Of Engineering; 01. Atılım University
Expansive soils exhibit considerable volume changes with moisture fluctuations leading to serious challenges for civil infrastructure, causing structural instability, pavement distortion, and foundation damage. While lime and cement remain widely used stabilizers, recent research has increasingly focused on waste-derived materials such as marble powder (MP) and expanded polystyrene beads (EPSb) as promising alternatives. These materials provide a practical approach to soil stabilization while contributing to the reuse of industrial by-products. In this study, the engineering behavior of high-plasticity clay was improved through the inclusion of MP and EPSb as additive materials. MP was added at 0%, 5%, 10%, 15%, and 20%, and EPSb at 0%, 0.3%, and 0.9% by dry weight of the high plasticity clay. Both additives were used alone and in combination. Laboratory tests, including Standard Proctor, free swell (FS), and unconfined compressive strength (UCS), were conducted. The results confirmed that the additives effectively reduced the liquid limit (LL) by 20.1% and the plasticity index (PI) by up to 22.4%. Results showed that EPSb effectively reduced FS and UCS, while MP decreased FS and increased UCS up to an optimal content. The most effective mixes achieved a maximum reduction of 54.7% in free swell (FS) (at 20% MP and 0.9% EPSb content) and a maximum increase of 13.1% in unconfined compressive strength (UCS) (at 5% MP content) compared to the untreated soil. The compaction tests further revealed a general decrease in optimum moisture content (OMC) and a slight increase in maximum dry density (MDD) with increasing MP content. Accordingly, the free swell (FS) and unconfined compressive strength (UCS) of the treated soils were predicted using multiple linear regression (MLR) and artificial neural network (ANN) models, developed from both the current experimental dataset and previously published studies. Input variables included untreated FS and UCS values, additive percentages, and one index property. The ANN model demonstrated superior predictive capability, achieving R2 values of 0.955 and 0.874 for FS and UCS, respectively, compared to 0.411 and 0.618 obtained with MLR. These results highlight the robustness of ANN in capturing nonlinear soil behavior and underscore its reliability and accuracy, particularly under limited data conditions.
Predicting Stroke Risk Using Machine Learning: A Data-Driven Approach to Early Detection and Prevention
(Wiley, 2025) Sutcu, Muhammed; Jouda, Dana; Yildiz, Baris; Katrib, Juliano; Almustafa, Khaled Mohamad; Industrial Engineering; 06. School Of Engineering; 01. Atılım University
Stroke is a major global health concern and a leading cause of disability and mortality, emphasizing the need for early risk prediction and intervention. This study leverages statistical analysis, machine learning (ML) classification, clustering, and survival modeling to identify key stroke predictors using a dataset of 5110 records. Descriptive statistics reveal that age, glucose levels, BMI, hypertension, and heart disease are the most influential risk factors. Stroke prevalence is notably higher among hypertensive (13.25%) and heart disease patients (17.03%), as well as among former (7.91%) and current smokers (5.32%). Clustering analysis using PCA and t-SNE highlights high-risk groups with elevated glucose levels and advanced age. Among ML models, XGBoost offers the best trade-off between precision and recall, while na & iuml;ve Bayes achieves the highest recall (0.404), detecting more stroke cases despite higher false positives. Feature importance analysis ranks glucose, BMI, and age as dominant predictors, with XGBoost emphasizing cardiovascular conditions. Survival analysis confirms increasing stroke risk beyond age 60, with the Kaplan-Meier and Cox models showing a 31.9% risk increase linked to hypertension. These findings underscore the importance of early screening, lifestyle intervention, and targeted care. Future research should explore data-balancing methods like SMOTE and develop real-time tools to support clinical decision-making.
Kulturkampf to Partykampf? Democratic Backsliding and Democratic Satisfaction in Turkey
(Routledge Journals, Taylor & Francis Ltd, 2025) Toros, Secil; Zeybek Kabakci, Gokce; Toros, Emre; 01. Atılım University; Industrial Design; 03. School of Fine Arts Design & Architecture; Department of Public Administration and Political Science; 17. Graduate School of Social Sciences
This article examines why satisfaction with democracy can remain comparatively high in Turkey despite sustained democratic erosion, focusing on the joint role of cultural conflict and partisan identity. It advances the concept of Partykampf, a partisan-cultural fusion that conditions democratic attitudes and satisfaction in this particular case. Interaction models show that satisfaction is not explained by culture or partisanship alone: alignment with the governing bloc strongly amplifies the positive effect of traditional-religious cultural alignment and strong partisan identity, whereas equally strong opposition partisans report markedly lower satisfaction. We conclude that Partykampf offers a powerful lens for understanding how legitimacy perceptions persist during backsliding by reframing democracy through partisan success rather than procedural standards.
Mobile Payment Adoption During the COVID-19 Pandemic: A Systematic Literature Review
(Palgrave Macmillan Ltd, 2025) Belbag, Aybegum Gungordu; 01. Atılım University; 05. School of Business; Business; Tourism Management
During the pandemic, the shift to non-physical transactions increased the need for mobile payments. This study aims to offer a systematic literature review on consumer behavior towards mobile payment during the pandemic, using the Theory, Context, Characteristics, and Methodology framework and following the Scientific Procedures and Reasons for Systematic Literature Reviews protocol. 47 articles from the WOS database were analyzed, revealing a dominance of quantitative studies, primarily based on the Technology Acceptance Model and UTAUT. Findings show that environmental stimuli and internal states (organism) shape behaviors and behavioral intentions (responses) towards mobile payments during the pandemic. The study concludes with future research directions grounded in the TCCM framework.
The Effect of Two Different Types of Daily Disposable Monofocal Contact Lenses on Ocular Wavefront Aberrations
(Elsevier, 2025) Yakar, Konuralp; 01. Atılım University
Background: To compare the effect of two daily disposable soft contact lenses on ocular wavefront aberrations. Methods: This study included 34 eyes from 17 patients aged 18 to 40 years (mean age: 27.12 +/- 8.3 years) with identical myopic refractive errors in both eyes without astigmatism and requesting contact lens use. Initially, wavefront aberrations; total, tilt, high, total coma, total trefoil, total 4.foil, sphere, high astigmatism, RMS (3 mm/5 mm) were measured using Nidek OPD Scan II aberrometer/topograph in both eyes without contact lenses. Acuvue Oasys with HydraLuxe 1-Day (senofilcon A) daily disposable contact lenses were applied to the right eye, while Precision 1 (verofilcon A) daily disposable contact lenses were applied to the left eye based on refractive errors. Wavefront aberration measurements were repeated 60 min later with contact lenses, and aberrations were compared to baseline and fellow eyes' measurements. The magnitudes of aberration changes after contact lens application were analyzed. Results: Both types of daily disposable contact lenses reduced total wavefront aberrations. Acuvue Oasys with HydraLuxe 1-Day contact lenses showed a significant increase in total trefoil aberration (p = 0.048). Precision 1 contact lenses showed a significant increase (p = 0.034) only in total tilt aberrations compared to baseline. No significant differences were found between the lenses regarding changes in all wavefront aberrations. Conclusion: Both daily disposable lenses effectively reduced total wavefront aberrations, though they increased certain subtypes of high-order aberrations in young adult myopes.
Epistemic Extraction Zones in Migration Studies: Rethinking Over-Research and Research Fatigue Among Syrian Refugees in Turkey
(Wiley, 2025) Ozdemir, Zelal; 01. Atılım University; 05. School of Business; Political Science and Public Administration
This paper explores the phenomenon of over-research among Syrian refugees in Turkey, highlighting how sustained and repetitive research attention has created research saturation zones that shape both refugee experiences and knowledge production. Drawing on unstructured conversations with six Syrian refugees in Ankara, the study examines how research fatigue manifests not only as reluctance to participate but also as strategic responses through which refugees navigate frequent encounters with researchers. While existing literature has addressed research fatigue and ethics in refugee studies, less attention has been given to how academic incentives, humanitarian logics, and policy imperatives intersect to produce systematic inequalities in knowledge production. To address this gap, the paper advances the concept of epistemic extraction zones, referring to contexts where knowledge is persistently mined from marginalized communities to satisfy institutional demands with limited reciprocity or epistemic agency. This conceptual lens shifts the debate from individual withdrawal to the structural political economy of knowledge production. The analysis identifies three key dynamics. First, the emergence of research saturation zones in contexts of protracted displacement, where the same communities are repeatedly targeted for study; second, refugees' strategic yet ambivalent engagement with research, combining pragmatic hope with critical awareness of its limited effects; and third, the paradoxical consequences of over-research, where intensified attention produces epistemic extraction that narrows the circulation of knowledge and reinforces hierarchies. The article also reflects critically on the researcher's own position within these dynamics. By theorizing epistemic extraction zones, the paper contributes not only to refugee studies but also to broader sociological debates on power, inequality, and the ethics of knowledge production, highlighting the need for more reflexive and politically accountable research practices.
Recognition and Misclassification Patterns of Basic Emotional Facial Expressions: An Eye-Tracking Study in Young Healthy Adults
(MDPI, 2025) Alkan, Neşe; 01. Atılım University; 02. School of Arts and Sciences; Department of Psychology
Accurate recognition of basic facial emotions is well documented, yet the mechanisms of misclassification and their relation to gaze allocation remain under-reported. The present study utilized a within-subjects eye-tracking design to examine both accurate and inaccurate recognition of five basic emotions (anger, disgust, fear, happiness, and sadness) in healthy young adults. Fifty participants (twenty-four women) completed a forced-choice categorization task with 10 stimuli (female/male poser x emotion). A remote eye tracker (60 Hz) recorded fixations mapped to eyes, nose, and mouth areas of interest (AOIs). The analyses combined accuracy and decision-time statistics with heatmap comparisons of misclassified versus accurate trials within the same image. Overall accuracy was 87.8% (439/500). Misclassification patterns depended on the target emotion, but not on participant gender. Fear male was most often misclassified (typically as disgust), and sadness female was frequently labeled as fear or disgust; disgust was the most incorrectly attributed response. For accurate trials, decision time showed main effects of emotion (p < 0.001) and participant gender (p = 0.033): happiness was categorized fastest and anger slowest, and women responded faster overall, with particularly fast response times for sadness. The AOI results revealed strong main effects and an AOI x emotion interaction (p < 0.001): eyes received the most fixations, but fear drew relatively more mouth sampling and sadness more nose sampling. Crucially, heatmaps showed an upper-face bias (eye AOI) in inaccurate trials, whereas accurate trials retained eye sampling and added nose and mouth AOI coverage, which aligned with diagnostic cues. These findings indicate that the scanpath strategy, in addition to information availability, underpins success and failure in basic-emotion recognition, with implications for theory, targeted training, and affective technologies.

Evaluating Space Efficiency Practices in Tehran's High-Rise Buildings: A Structural and Architectural Perspective
(Wiley, 2025) Mazaherylaghab, Hamed; Haghi, Marzieh; Ilgin, Huseyin Emre; Aslantamer, Ozlem Nur; 01. Atılım University; Interior Architecture and Environmental Design; 03. School of Fine Arts Design & Architecture
Spatial efficiency in Tehran's high-rise building design is shaped by a complex blend of multiple factors such as architectural and structural considerations. Tehran's innovative and flexible strategies have allowed the city to address the complexities of high-rise design considerations, resulting in the creation of some of the most progressive and sustainable tall buildings in the Middle East. However, detailed studies on space utilization in Tehran's tall towers remain scarce. This article addresses this gap by analyzing 48 case study towers, revealing key trends such as the dominance of residential functions, central core designs, prismatic forms, and the frequent use of steel rigid frame systems. The analysis revealed an average spatial efficiency of 91% in Tehran's towers, with a core-to-GFA (gross floor area) ratio of only 6%, exceeding typical efficiency ratios observed in other regions, though shaped by Tehran's specific urban and economic context. These findings promote sustainability and provide crucial insights for construction professionals, supporting the informed decision-making process for tall building projects in Tehran and other densely urbanized areas.

Factors Affecting Dentists' Intention To Adopt Artificial Intelligence: An Extension of the Unified Theory of Acceptance and Use of Technology (UTAUT) Model
(Emerald Group Publishing Ltd, 2025) Alqaifi, Faten; Tengilimoglu, Dilaver; Business; 05. School of Business; 01. Atılım University
PurposeAdvancements in science and technology have integrated artificial intelligence (AI) into dentistry, improving treatment processes, operational efficiency, and clinical outcomes. However, AI adoption among dentists remains underexplored, hindering progress in oral healthcare. This study aims to identify key barriers to AI adoption and examine factors influencing dentists' intention to use AI.Design/methodology/approachA quantitative cross-sectional approach was employed, utilizing self-administered questionnaires distributed online and across various dental clinics and hospitals in Ankara, Turkey. A total of 440 dentists participated in the study. Data analysis was conducted using SPSS and SmartPLS.FindingsThe study found that AI-anxiety negatively affects the intention to adopt AI in dentistry, showing a medium (almost large) effect that is stronger than other UTAUT factors such as performance expectancy, effort expectancy, and social influence, which demonstrated only small effects. Dentists with higher anxiety about learning and sociotechnical blindness are less likely to adopt AI, while concerns about job replacement and AI-configuration have less but still significant impact.Research limitations/implicationsThese results contribute to the growing body of knowledge on technology adoption in oral healthcare and provide practical implications for technology developers, policymakers, and other stakeholders seeking to facilitate AI integration in dentistry.Originality/valueThis study provides novel insights into AI adoption in dentistry, offering guidance for future development and integration, and addressing a critical research gap in a growing field-particularly in Turkey, where implementation is still in its early stages.
Queer Lives in the Social Media Prism: Precarious LGBTQIA Plus Visibility and Lateral Surveillance in Azerbaijan
(Sage Publications Inc, 2025) Seyidov, Ilgar; Pentzold, Christian; Public Relations and Advertising; 05. School of Business; 01. Atılım University
In countries where state institutions and the public largely reject LGBTQIA+ identities and issues, queer people struggle with visibility. Next to governments and technology providers, what queer people do, who they connect to, and how they express themselves is being watched and scrutinized by their families and proximate relations. This lateral surveillance is afforded by social media that establish, as we argue in this article, a prism. Here, LGBTQIA+ lives become refracted as extensive though incoherent patterns of digital traces. How queer people respond to this situation where the binary of visible versus invisible falls apart is poorly understood. To address that gap, we interrogate the precarious management of visibility attempted by LGBTQIA+ people in Azerbaijan with its heteropatriarchal, honor-driven culture. Based on our exploratory interview study, we find that queer Azerbaijanis were confronted with a highly ambivalent scopic setup where context collision loomed large. In effect, they supported LGBTQIA+ visibility but had personally decided not to live or promote it. Yet whilst their attempts to remain opaque may contradict their activistic compliancy, this was a logical reaction to too hard to handle terms of visibility.
