The Turkish Adaptation, Validity, and Reliability of the Fragmented Self Inventory
(Association for Clinical Psychology Research, 2025) Akın, Z.G.; Türkarslan, K.K.; 01. Atılım University
The Fragmented Self Inventory (FSI) is a self-report measurement tool developed to examine the experiences of fragmented self as defined by Heinz Kohut. The scale focuses on the experiences in two axes of the self in the context of psychoanalytic self-psychology, namely fragmented grandiosity (FSI-FG) and fragmented idealization (FSI-FI). This study aimed to adapt the FSI into Turkish and to evaluate its psychometric properties in a Turkish-speaking sample. Data were collected from 495 participants (female = 67.88%, Mage = 33.86, SD = 12.87). Confirmatory factor analysis was conducted to test the two-factor structure of the FSI. The convergent validity of the scale was evaluated by examining the relationships of the FSI-FG and FSI-FI scores with self-esteem, pathological narcissism, self-control, discipline, emotion dysregulation, meaning in life and purpose, depression, anxiety, and stress variables. The reliability of the scale was examined by internal consistency coefficients and test-retest intraclass correlations. The results of confirmatory factor analysis supported the two-factor structure of the Turkish FSI. Higher scores on the axis of fragmented grandiosity were associated with lower self-esteem and higher symptoms of pathological narcissism, whereas higher scores on fragmented idealization were associated with poorer self-control, lower discipline, higher difficulties in emotion regulation, and higher difficulty in finding meaning and purpose in life, supporting the convergent validity of the FSI. The FSI-FG and FSI-FI subscales showed satisfactory internal consistency (McDonald’s ω = .77 and .86) and four-week test-retest reliability (ICC = .78 and .81). In the path analysis in which fragmented grandiosity and fragmented idealization predicted depression, anxiety and stress, it was found that fragmented grandiosity significantly predicted anxiety and stress, and fragmented idealization significantly predicted depression, anxiety and stress. The findings of this study indicate that the Turkish form of the FSI can be used to measure experiences of fragmented grandiosity and fragmented idealization. © 2025 Elsevier B.V., All rights reserved.
A Comparative Analysis of Skyscraper Design Characteristics in the Middle East, Asia, and North America
(Hapres Limited, 2025) Ilgın, H.; Aslantamer, Ö.; 01. Atılım University
The proliferation of skyscrapers in rapidly urbanizing regions necessitates a comparative understanding of architectural and structural design strategies. The Middle East, Asia, and North America have emerged as dominant centers of high-rise development, each influenced by unique environmental, cultural, and economic conditions. This study employs a case study approach, analyzing 133 skyscrapers (≥300 m) using qualitative and quantitative metrics. The analysis focuses on core typology, structural systems, materials, and architectural form, based on data extracted from the Council on Tall Buildings and Urban Habitat (CTBUH) database. Findings reveal regional distinctions: Asian skyscrapers favor tapered and composite designs with outriggered frame systems; Middle Eastern towers emphasize prismatic forms using concrete; and North American high-rises balance setback and prismatic forms with concrete and shear-frame systems. A central core layout dominates all regions, driven by efficiency and safety considerations. These insights offer valuable benchmarks for architects, engineers, and urban planners aiming to optimize skyscraper design in dense urban contexts. These insights offer valuable benchmarks for architects, engineers, and urban planners aiming to optimize high-rise design in dense urban contexts. © 2025 Elsevier B.V., All rights reserved.
Studies of Hadronic Showers in SND@LHC
(Institute of Physics, 2025) Abbaneo, D.; Ahmad, S.; Albanese, R.; Alexandrov, A.; Alicante, F.; Aloschi, F.; Zamora-Saá, J.; 01. Atılım University
The SND@LHC experiment was built for observing neutrinos arising from LHC pp collisions. The detector consists of two sections: a target instrumented with SciFi modules and a hadronic calorimeter/muon detector. Energetic νN collisions in the target produce hadronic showers. Reconstruction of the shower total energy requires an estimate of the fractions deposited in both the target and the calorimeter. In order to calibrate the SND@LHC response, a replica of the detector was exposed to hadron beams with 100 to 300 GeV in the CERN SPS H8 test beam line in Summer 2023. This report describes the methods developed to tag the presence of a shower, to locate the shower origin in the target, and to combine the target SciFi and the calorimeter signals so to measure the shower total energy. © 2025 Elsevier B.V., All rights reserved.
Evaluating Space Efficiency Practices in Tehran's High-Rise Buildings: A Structural and Architectural Perspective
(John Wiley and Sons Ltd, 2025) Mazaherylaghab, H.; Haghi, M.; Ilgın, H.; Aslantamer, Ö.; 01. Atılım University
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. © 2025 Elsevier B.V., All rights reserved.
Role of Latissimus Dorsi–Thoracolumbar Fascia Complex Stretching on Pain and Pain-Related Parameters in Patients with Chronic Low Back Pain: A Randomised Clinical Trial
(John Wiley and Sons Inc, 2025) Uluǧ, N.; Kodak, S.B.; Kodak, M.İ.; Aslan, S.N.; 01. Atılım University
Background: Fascial stretching is gaining interest as a potential intervention for pain management. However, evidence regarding the effect of latissimus dorsi–thoracolumbar fascia (LD-TLF) complex stretching in patients with chronic low back pain (CLBP) remains limited. Therefore, this study aimed to investigate the effects of LD-TLF complex stretching on pain-related factors and disability in patients with CLBP. Methods: Thirty patients with CLBP were randomly assigned to a study group (n = 15; 7 men, 8 women) and a control group (n = 15; 7 men, 8 women). The study group received 4 weeks of LD-TLF complex stretching in combination with conventional physiotherapy, while the control group received conventional physiotherapy only. Outcomes were assessed before and after the interventions, including primary measures of pain pressure thresholds (PPT) at thoracolumbar fascia levels (L1, L3 and 12th costa), and secondary measures included the Pain Sensitivity Questionnaire (PSQ), the effects of pain on daily activities measured by the Brief Pain Inventory (BPI), and disability assessed by the Oswestry Disability Questionnaire (ODQ). Results: Pre- and post-treatment PPTs, at the L1, L3 vertebrae and 12th costa levels, demonstrated significant differences between the study group and control groups. Post-treatment thresholds were significantly higher compared to pre-treatment thresholds (p < 0.001, ηp2 = 0.67; p < 0.001, ηp2 = 0.61; p < 0.001, ηp2 = 0.74). Additionally, significant improvements were found in PSC, BPI and ODQ scores in the study group compared to the control group (p < 0.05). Conclusion: The results of this study suggest that stretching the LD-TLF complex may be a beneficial addition to the conventional physiotherapy approach for patients with CLBP. Specifically, LD-TLF complex stretching, when used in combination with conventional physiotherapy, appears to provide improved pain thresholds, decreased pain sensitivity and pain during activity, as well as reduced disability compared to conventional physiotherapy alone in patients with CLBP. Significance Statement: Chronic low back pain (CLBP) is a multifactorial condition, with the thoracolumbar fascia increasingly recognized as a potential contributing factor. This study suggests that stretching the latissimus dorsi-thoracolumbar fascia complex in combination with conventional physiotherapy, enhances pain thresholds, reduces pain sensitivity, and decreases disability in individuals with CLBP. Incorporating fascia-specific interventions into CLBP treatment programs could offer significant benefits for both patients and clinicians. © 2025 Elsevier B.V., All rights reserved.

Making Foreign Policy Through Twitter: An Analysis of Trump’s Tweets on Iran
(IGI Global, 2022) Orhan, D.D.; 01. Atılım University
Through the development of technology, the understanding of traditional foreign policy has changed. Foreign policy making, which was shaped by diplomatic correspondence, visits, agreements, and notes between countries, is carried out today via messages sent over the Internet. Twitter is the most frequently used internet tool in the hands of institutions, decision makers, and leaders in foreign policy making. US President Donald J. Trump is one of the leaders who use Twitter most effectively. Twitter was the center of Trump’s messages, both during the presidential campaign and after his election. Trump is not just using Twitter as a platform for meeting his supporters and announcing the country’s official policies. Twitter has also been an important way for Trump to challenge and send harsh messages to certain countries, companies, and individuals. Iran is one of the countries that Trump targets through Twitter. This study aims to examine the use of Twitter as a platform in foreign policy making by using content analysis method through Trump’s tweets about Iran. © 2025 Elsevier B.V., All rights reserved.
Two-Way Interaction Feature of Social Media Tools: The Twitter Example
(IGI Global, 2022) Seyidov, I.; 01. Atılım University
The internet and development of information technologies brought about the emergence of digital communication tools. In this vein, social media have become a phenomenon in terms of creating informative, interactive, and participatory platforms for the individuals. The social media tools have become prominent not only for public relations or communications experts, but also for politicians, scholars, groups, brands, organizations, etc. One of the effective social media tools is Twitter, which has been focus of political communication research due to its tendency of creating discussion platform that allows the users to involve in and interact with each other. This study focused on how Twitter creates the two-way interaction for the users and what the main components of this interaction are. In addition, the contribution of Twitter to organizational promotion was also another concern of the study. In this context, the research focuses on both inter-organizational and individual levels. Multiple case study technique was used as research technique. Five different cases were analyzed. © 2025 Elsevier B.V., All rights reserved.

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.
4D-Printed Continuous Fiber-Reinforced PLA/TPU Auxetic Composites: Mechanical Performance, Energy Absorption, Shape Recovery, and Reusability Evaluation
(SpringerNature, 2025) Alkan, Atakan; Ranjbar Aghjehkohal, Amin; Fallah, Ali; Koc, Bahattin; 01. Atılım University
This study explores the mechanical performance, energy absorption, shape recovery, and reusability of 4D-printed continuous carbon fiber-reinforced auxetic composite structures based on PLA/TPU blends, designed for load-bearing applications. PLA-TPU mixtures with different TPU content were developed to optimize the balance between flexibility and strength, with carbon fibers incorporated to enhance the mechanical properties of the resulting composites. Thermo-mechanical characterization of the blends was conducted, followed by a detailed evaluation of the structures' mechanical behavior and energy absorption capacity under room temperature conditions, simulating practical industrial scenarios. The shape recovery performance of these composite structures was also investigated. To assess reusability, the programming-recovery cycle was repeated five times, analyzing the retention of mechanical properties and shape recovery over multiple cycles to determine durability. Results revealed that TPU integration provided sufficient flexibility for cold programming, while carbon fiber reinforcement significantly enhanced stiffness and strength. The 4D-printed composites exhibited consistent shape recovery and maintained mechanical integrity after five cycles, confirming their reusability. These findings demonstrate the potential of 4D-printed PLA/TPU-based carbon fiber-reinforced composites as smart, durable materials for load-bearing applications in industries such as biomedical engineering, automotive, and aerospace.
PMMA-Based Electrospun Composite Fibers for Dye Adsorption From Water
(Sage Publications Ltd, 2025) Cakar, Ilknur; Yesil, Sertan; Bayram, Goknur; Chemical Engineering; 06. School Of Engineering; 01. Atılım University
Poly (methyl methacrylate) (PMMA) and PMMA/poly (ethylene glycol) (PEG)-based composite fibers were produced using electrospinning technique with two different additives; halloysite nanotubes (HNTs) and boron phosphate (BPO4). The effect of the additives on the morphology, wettability and dye adsorption properties of electrospun fibers were investigated by Scanning Electron Microscopy (SEM), water contact angle measurement and UV-VIS spectrophotometry. The results of SEM analysis indicated that addition of PEG resulted in thinner average fiber diameter and beaded structure. Additionally, it was also observed that incorporating both HNT and BPO4 to the PMMA solution caused increased fiber diameter which might be due to increased solution viscosity. For PMMA fibers containing 3 wt% HNT, the highest average diameter and water contact angle were measured as 2204 +/- 302 nm and 110.29 +/- 3.9 degrees, respectively. The produced fibers were tested for the capability to adsorb methylene blue (MB) and methyl orange (MO) from aqueous solutions. Dye adsorption capacity of the samples increased by addition of HNT and BPO4. According to adsorption capacity results, PMMA/PEG/BPO4 composite sample containing 5 wt% BPO4, with an adsorption capacity of 0.76 mg/g, was determined as adsorbent for kinetic and isotherm studies. The adsorption kinetics were well described by the pseudo-second-order model, and equilibrium data were correlated with the Langmuir model.
A Factory in a Time of Turmoil: The Establishment and Engineering of the Büyükdere Match Factory in 1930s Istanbul
(MDPI, 2025) Tunc, Gokhan; Tunc, Tanfer Emin; Civil Engineering; 06. School Of Engineering; 01. Atılım University
The Republic of Turkey established its first match factory in Sinop in 1929 but had to relocate it even before it was in operation due to severe structural damage caused by ground settlement. In July 1930, through his US-based firm the American-Turkish Investment Corporation (ATIC), the Swedish "Match King" Ivar Kreuger signed a contract with the Republic of Turkey to build and operate a factory in B & uuml;y & uuml;kdere, Istanbul. By 1930, Kreuger had already established a match production monopoly in nearly every country in Europe and that year created a similar financial system for Turkey, gaining control of match production for 25 years. This article explains the events surrounding the establishment of his modern production facility in Turkey, with a particular focus on its engineering aspects. It details the strategically chosen location, the engineering solutions for the factory's construction, its production lines, and what the country gained and lost from it. In order to determine the establishment and production processes of the facility, the authors examined domestic and foreign archival documents, firsthand news reports from the period, articles and theses, and all other available documents. After the contract was terminated by both parties, the Turkish government and ATIC, in May 1943, the factory continued its production and storage activities until May 1989. At that point, the factory and all its equipment were integrated into another existing facility in the & Idot;neg & ouml;l district of Bursa province. Almost all the buildings of the B & uuml;y & uuml;kdere Match Factory were demolished, and the land was repurposed for a 450-bed regional hospital in 2012. In short, this article deploys the B & uuml;y & uuml;kdere Match Factory as a case study to examine what Turkey gained and lost from the establishment and production processes of a modern industrial factory, enabled by US-Turkish collaboration, and equipped with the most advanced manufacturing and engineering technologies of the time.
Estimation of Parameters for a System Equipped with Protection Block
(Elsevier, 2026) Kus, Colkun; Eryilmaz, Serkan; Industrial Engineering; 06. School Of Engineering; 01. Atılım University
This paper studies the problem of estimating unknown parameters involved in a system which is equipped with a protection block. The system has different failure rates depending on whether the protection block is present or not, as the protection block is modeled by its own lifetime distribution and contributes an additional failure component to the system. The model is analyzed under the assumption of exponentially distributed lifetimes, leading to the study of its distributional properties and the estimation problem for its unknown parameters. Closed-form expressions for the maximum likelihood estimators are obtained. Furthermore, theoretical expectations and variances of the estimators are derived. We also discuss the stress-strength reliability estimation problem and construct confidence intervals for the associated reliability measure. Numerical results are provided to demonstrate the implementation of the proposed methods.
Transcatheter Aortic Valve Implantation in Nonagenarians: A Comparative Analysis of Baseline Characteristics and 1-Year Outcomes
(MDPI, 2025) Guney, Murat Can; Bozkurt, Engin; 01. Atılım University
Background: Transcatheter aortic valve implantation (TAVI) is increasingly used in elderly patients with severe aortic stenosis, yet data on nonagenarians remain limited. This study aimed to compare clinical characteristics and outcomes of patients aged >= 90 years with those aged <90 years undergoing TAVI. Methods: We retrospectively analyzed 620 patients who underwent transfemoral TAVI. Patients were divided into two groups: <90 years (n = 545) and >= 90 years (n = 75). Baseline clinical, procedural, and outcome data were compared. Results: Nonagenarians had lower body mass index (BMI) and a lower prevalence of comorbidities such as diabetes, hyperlipidemia, and prior coronary artery bypass grafting CABG (all p < 0.05). All-cause mortality was higher in nonagenarians at 1 month (8.0% vs. 5.5%, p = 0.425), 6 months (9.3% vs. 7.9%, p = 0.838), and 1 year (21.3% vs. 16.7%, p = 0.405), though these differences were not statistically significant. In-hospital stroke occurred more frequently in patients >= 90 years (6.7% vs. 2.2%, p = 0.044). Conclusions: Despite a higher rate of in-hospital stroke, nonagenarians undergoing TAVI had comparable mortality outcomes to younger patients. These findings support the feasibility of TAVI in selected very elderly patients, while highlighting the need for tailored stroke prevention strategies. Trial Registration: The trial is retrospectively registered, and a clinical trial number is not applicable.

This paper aims to generalize and improve the recent fixed-point theorems in the setting of interpolative metric spaces. More precisely, we investigate the existence and uniqueness of the fixed-point for certain operators of the Ciric-Reich-Rus-type, via admissible mapping in the context of interpolative metric spaces.
A New Conservative Numerical Method for Strongly Coupled Nonlinear Schrödinger Equations
(Springer Heidelberg, 2025) Ors, Ridvan Fatih; Koroglu, Canan; Aydin, Ayhan; Mathematics; 02. School of Arts and Sciences; 01. Atılım University
In this paper, a numerical method based on the conservative finite difference scheme is constructed to numerically solve the strongly coupled nonlinear Schr & ouml;dinger (SCNLS) equation. Conservative properties such as energy and mass of the SCNLS equation have been proven. In particular a fourth-order central difference scheme is used to discretize the the spatial derivative and a second-order Crank-Nicolson type discretization is used to discretize the temporal derivative. It has been shown that the proposed scheme preserves the discrete mass and energy. The existence of discrete solution is also investigated. Several numerical results are given to demonstrate the preservation properties of the new method. Also, the effect of the linear coupling parameters on the evolution of solitary waves is investigated.
