(Springer, 2026) Görgülü, Volkan; Tomruk, Cansın Şirin; Ergün, Pelin; Özdil, Berrin; Sancı, Ebru; Buhur, Aylin; Sözmen, Eser Y.; Köse, Timur; Yavaşoğlu, Nefise Ülkü Karabay; Yavaşoğlu, Altay
Epilepsy is one of the most prevalent neurological disorders worldwide, and approximately 25% of patients remain refractory to pharmacological treatment. Blood–brain barrier (BBB) disruption and reactive gliosis are key mechanisms implicated in early epileptogenesis. This study investigated the effects of zafirlukast, a leukotriene receptor antagonist, on BBB permeability, reactive gliosis, and behavioral seizure activity in a pentylenetetrazol (PTZ)-induced early epileptogenesis model in C57BL/6 mice. Zafirlukast was administered twice daily at a dose of 10 mg/kg. Seizure activity was evaluated by behavioral observation in terms of seizure severity, latency, duration, and frequency. BBB permeability was assessed using the Evans Blue assay, and brain tissues were analyzed by biochemical and immunohistochemical methods. The PTZ + ZAFIR group exhibited more severe seizures, characterized by increased seizure frequency and duration, shorter latency, and a higher kindling rate (80% vs. 27%). BBB permeability was also increased, whereas MMP-9 levels remained, suggesting disruption may be linked to direct mechanical effects of recurrent seizures rather than inflammation. Clues suggest that zafirlukast may exert paradoxical effects on two prominent cell types involved in reactive gliosis. While increased GFAP and TGF-β1 expression may reflect enhanced astrocyte activation, changes in IL-1β and Iba1 expression suggest suppression of microglial activation. Notably, pro-inflammatory and oxidative stress markers remained unchanged despite the increase in seizure severity. The observed reduction in neurodegeneration may be attributable to the suppressive effects of zafirlukast on microglial activation and the subsequent reduction in pro-inflammatory cytokine release. These findings indicate a complex role for leukotriene signaling during early epileptogenesis. Further studies using different doses, vehicles, and experimental models are warranted to clarify the effects of zafirlukast on the mechanisms underlying early epileptogenesis. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2026.
Assessing Metabolic and Reproductive Consequences of Prenatal Paracetamol Exposure in Female CD1 Mice
(Wiley, 2026) Entezari, Bita; Bozdağ, Deniz; İnce-Ergüç, Elif; Buhur, Aylin; Tomruk, Cansın Şirin; Sabuncuoğlu, Suna; Yavaşoğlu, Altuğ; Gürer, Orhan Hande
Paracetamol is a widely used analgesic during pregnancy; however, emerging evidence suggests it may act as an endocrine/ metabolism disrupting compound. Using an F1 female CD1 mouse model, this study scrutinized the long-term metabolic and reproductive consequences linked to intrauterine paracetamol exposure. Pregnant dams were administered paracetamol at three dose levels (Cmax/10, Cmax, and Cmax×10) during a critical window of organogenesis (gestational days 7.5–16.5). Offspring were monitored until 17weeks of age to assess growth, glucose homeostasis, lipidomic profiles, and ovarian histology. Prenatal exposure did not significantly affect total body weight but induced a dose-dependent increase in peritoneal adipose tissue mass, particularly in the Cmax×10 group. Metabolic assessments revealed impaired glucose tolerance in the Cmax/10 group and increased insulin sensitivity across all dose groups. Adipose tissue gene expression analysis demonstrated upregulation of adipogenic markers (Pparγ, Lpl, Fasn), while untargeted lipidomics revealed consistent dysregulation of lipid species, including lysophosphatidylcholines (LPCs), phosphatidylcholines (PCs), sphingomyelins (SMs), and triacylglycerols (TGs), indicating altered lipid storage and inflammatory signaling. Histological evaluation showed a marked reduction in total follicle number and increased follicular atresia following paracetamol exposure. Degenerative changes in oocytes and granulosa cells were observed, and multi-oocyte follicles (MOFs) were detected exclusively in the Cmax/10. Collectively, these findings demonstrate that intrauterine paracetamol exposure induces persistent developmental reprogramming in female offspring, characterized by visceral adiposity, disrupted lipid homeostasis, and depletion of the ovarian reserve. Notably, several endpoints exhibited non-monotonic dose–response relationships, underscoring the sensitivity of developing systems to even subtherapeutic paracetamol exposure.

(Emerald Group Publishing, 2026) Kızıldemir. Özgür; Şengel, Ümit; Çakmak, Muzaffer; İbiş, Salim; İnan, Ramazan
Purpose – The study aims to focus on the challenges that artificial intelligence (AI) brings to career decisions among tourism employees, while on the other hand, it focuses on how tourism employees’ AI risk perceptions affect their career decisions. In addition, another aim of the study is to reveal problem-solving strategies and future vision from a sector-based and managerial perspective for possible employment problems. Design/methodology/approach – In the first stage of my study, which used a mixed-method approach, data was obtained from 423 tourism employees (accommodation, food and beverage and travel) in Istanbul through a survey, while in the second stage, data was obtained from 25 managers (accommodation, food and beverage and travel) working in tourism establishments in Istanbul through interview forms. Findings – The results of the study revealed that AI risk perceptions affect tourism employees’ career decisions, while the professional motivation and anxiety levels of employees significantly mediated this effect. For the potential employment problems that these results will reveal, sub-sectors in tourism are trying to produce solutions with strategies such as technology investments and employee adaptation. Originality/value – This study fills an important gap in the literature by revealing that AI, which has the potential to increase service delivery and operational efficiency, affects employees’ career decisions and that businesses act with the mission of producing solutions with this awareness.
Psychological Flexibility and Academic Self-Efficacy: The Roles of Well-Being Literacy and Burnout-Driven Self-Stigma
(Hogrefe AG, 2026) Aksoy, Şeyhmus; Konuk, Ayşe; Alkhulayfi, Abdulmohsen Mohammed Abdullah; Gomez-Salgado, Juan; Yıldırım, Murat
Introduction: Despite the beneficial effects of academic self-efficacy, there is a relatively limited focus on the academic self-efficacy of higher education students compared to studies on student self-efficacy in other educational stages. Aim: The present study employs a moderated mediation model to investigate whether well-being literacy mediates the relationship between psychological flexibility and academic self-efficacy, while also exploring how burnout-driven selfstigma is associated with these direct and indirect relationships. Methods: A cross-sectional research design was employed in the present study. The sample comprised 316 students (82.6% female; M = 22.28, SD = 3.38). Participants completed the Academic Self-Efficacy Scale, the Psychological Flexibility Scale, the Well-Being Literacy Scale, and the Burnout-Driven Self-Stigma Scale. Results: Our study indicated that psychological flexibility was associated with reduced academic selfefficacy both directly and indirectly through well-being literacy. However, conditional direct and indirect effect results suggested that higher levels of burnout-driven self-stigma were related to decreased positive direct and indirect effects. Discussion/Conclusion: This study provides evidence to improve our understanding of how psychological flexibility relates to academic self-efficacy. While research on burnout-related self-stigma and well-being literacy remains limited, this study highlights how these variables were examined within the proposed model as potential moderator and mediator constructs.
Asynchronous recovery of medial and lateral gastrocnemius mechanical properties and jump performance following localized plantar flexor fatigue
(BMC, 2026) Şahbaz, Yasemin; İlez, Ali; Batur, Nergiz
Objective: To investigate the acute and short-term (24 h) effects of localized plantar flexion fatigue on muscle mechanical properties, countermovement jump (CMJ) kinetics, and dynamic balance, focusing on recovery profiles of the gastrocnemius medialis (MG) and lateralis (LG). Design: Prospective, repeated-measures experimental study. Methods: Twenty-eight healthy volunteers (n = 28) performed a standardized unilateral isometric plantar flexion fatigue protocol until task failure (Borg CR-10 ≥ 8). Assessments were conducted at baseline, immediately post-fatigue, and 24 h post-fatigue (24 h). Outcomes included myotonometric properties (tone, stiffness, elasticity, relaxation time, and creep) of the MG and LG via MyotonPRO, CMJ kinetics via force plate, and dynamic balance via the Modified Star Excursion Balance Test (mSEBT). Results: Significant Time × Region interactions were found for stiffness (P = 0.038, ηp² = 0.276) and relaxation time (P = 0.024, ηp² = 0.171). Both muscle heads showed an acute decrease in stiffness (P < 0.001); however, LG stiffness recovered by 24 h (P = 0.330), while MG stiffness remained reduced (P < 0.05). Although CMJ height recovered at 24 h (P = 0.842), eccentric and braking phase durations remained prolonged (P < 0.001; ηp² = 0.357 and ηp² = 0.264), indicating altered neuromuscular strategies. For dynamic balance, a delayed impairment was observed in anterior reach distance, which declined only at 24 h compared to baseline (P = 0.021, ηp² = 0.133). Conclusion: Localized plantar flexion fatigue induces region-specific mechanical alterations and asynchronous recovery. Restoration of jump height at 24 h masks persistent deficits in eccentric phase durations and MG stiffness. These findings highlight a “neuromuscular vulnerability window” at 24 h post-fatigue, where delayed impairments in MG mechanics and anterior stability may increase potential susceptibility to injury despite apparent recovery. Practically, monitoring head-specific muscle mechanics, rather than global performance outcomes, is critical during this 24 h window to optimize training modification and guide objective return-to-play decisions.

The relationship between income inequality and energy poverty in the context of sustainable development goals: A micro-instrumental variables estimation in Türkiye
(Elsevier, 2026) Günay, Simge; Kayacan, Bekir; Uçal, Meltem
Energy poverty has adverse consequences on individuals’ lives. It endangers their health, interrupts their education, and may even undermine equality both within and between them. Since income inequality remains a significant problem on the path to achieving sustainable development in Türkiye, identifying its determinants on a micro scale is of great importance. In this regard, this study analysed the relationship of energy poverty to personal income inequality in Türkiye, utilising the TurkStat 2017-2020 income and living conditions survey micro-panel dataset. Instrumental variables estimation was used, and robustness checks were applied to achieve this aim. According to this, energy poverty is negatively related to personal income inequality. To check for heterogeneity, this relationship was re-examined within three income groups. The findings suggested that while energy poverty is positively related to personal income inequality at the bottom of the income distribution, it is negatively related to personal income inequality at the top of the income distribution. This study mainly contributes to the literature by providing the first micro-level evidence on the relationship between income inequality and energy poverty. A combination of targeted social and energy policies is required to tackle both energy poverty and income inequality on the micro scale in Türkiye.
INVESTIGATION OF THE REASONS FOR PREFERENCE AND EMPLOYMENT EXPECTATIONS OF INTERNATIONAL STUDENTS STUDYING IN THE DEPARTMENT OF PHYSIOTHERAPY AND REHABILITATION IN TÜRKİYE
(Turkish Physiotherapy Association, 2026) Karagözoğlu Coşkunsu, Dilber; Tosun, Anıl; Demirbüken, İlksan; Avcı, Ender Ersin; Çağlar, Engin; Aktar Reyhanıoğlu, Duygu; Okur Dündar, Şule; Polat, Mine Gülden
To investigate the reasons why international students (ISs) studying in the Physiotherapy and Rehabilitation (PTR) departments in T & uuml;rkiye chose to study in this field and their employment expectations, using sample from one public and two foundation universities in & Idot;stanbul. Methods: A total of 564 students were invited to participate in the study. Participants were asked to complete a 12-item questionnaire prepared by the researchers, which assessed their reasons for choosing PTR education in T & uuml;rkiye and their career plans after graduation. Results: A total of 267 students participated in the study (200 from Turkish-medium programs and 67 from English-medium programs). The most cited reason for choosing to study in T & uuml;rkiye among both Turkish-and English-medium students was cultural similarity [60% (n=200); 58.2% (n=39), respectively]. Among Turkish-medium students, 50.2% planned to work in T & uuml;rkiye, and 17.4% planned to return to their home countries. Additionally, 76.1% expressed interest in pursuing graduate studies in T & uuml;rkiye. Among English-medium students, 28.4% intended to work in T & uuml;rkiye, and 11.9% planned to return home. In this group, 61.2% stated that they were considering graduate education in T & uuml;rkiye. There was a statistically significant difference between the two groups in terms of the percentage of students who intended to work or pursue graduate education in T & uuml;rkiye (p=0.001 and p=0.018, respectively). Conclusion: According to our findings, a significant proportion of ISs, particularly those studying in Turkish-medium PTR programs, intend to work in T & uuml;rkiye after graduation. This should be taken into account in workforce planning efforts for physiotherapists.
Exercise Interventions for Improving Balance, Strength, and Functional Capacity in Older Adults: A Randomized Controlled Trial
(Human Kinetics, 2026) Özdincler, Arzu Razak; Yiğit, Şafak; Umut, Gülsena Utku; Ekşi, Büşra Ülker; Güney, İrem
Age-related declines in strength and balance increase fall risk in nursing home residents. This study compared the effects of the modified Otago Exercise Program and the Large-Amplitude Functional Exercise Program (LAFEP) on fall risk, balance, functional capacity, and lower-extremity strength. In this randomized controlled trial, 70 participants (aged >= 65) residing in nursing homes were randomly assigned to the modified Otago Exercise Program (n = 35) or the LAFEP (n = 35). Both groups received supervised group exercise three times weekly for 12 weeks. Primary outcomes were the functional reach test and the timed up-and-go test. Secondary outcomes included the Performanz Balance System, the 6-min walk test, and the five times sit-to-stand test. Both interventions led to significant within-group improvements (p < .05). However, the LAFEP group demonstrated significantly greater improvements in dynamic balance, specifically in the functional reach test (p = .03). Improvements in functional mobility outcomes, including the timed up-and-go (p = .67) and the five times sit-to-stand tests (p = .17), were also more pronounced in the LAFEP group; however, these between-group differences did not reach statistical significance. Both the modified Otago Exercise Program and the LAFEP were effective in enhancing balance and functional outcomes for older adults in residential care. The LAFEP, however, yielded superior gains specifically in dynamic balance. The findings suggest that the LAFEP, adapted from neurorehabilitation principles, may be a viable and potentially more effective alternative to conventional fall prevention exercise programs for this population.
Assessment of Surface Roughness and Bacterial Adhesion of Occlusal Splints Fabricated with Different Layer Thicknesses, Polishing Techniques and Build Orientations
(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Dede, Merve; Saygılı, Sina; Topçuoğlu, Nursen
This study evaluated the combined effects of build orientation, layer thickness, and polishing protocols on surface roughness and bacterial adhesion of occlusal splints. Ten disc-shaped specimens (Ø16 × 3 mm) were fabricated for each group using a digital light processing (DLP)-based 3D printer. Specimens were printed at two orientations (0° and 90°) and two layer thicknesses (50 and 100 µm) using a splint resin. Surface roughness was measured with a contact profilometer, and bacterial adhesion was measured by optical density (OD) readouts for Streptococcus mutans using a spectrophotometer. Surface morphology was examined by field-emission scanning electron microscopy (SEM). Statistical analyses were performed using jamovi. Because normality and/or homogeneity assumptions were not met, robust analysis of variance was applied. Polishing protocol significantly affected surface roughness (Ra) values. Unpolished specimens showed the highest Ra values, whereas mechanical polishing combined with centrifugation produced the lowest values. No significant main effects of polishing protocol, layer thickness or orientation were observed for bacterial adhesion. SEM findings supported the roughness results. Surface roughness was primarily influenced by polishing protocols and their interactions, whereas bacterial adhesion remained relatively stable. The weak Ra–OD correlation indicated that surface roughness alone was not a reliable predictor of bacterial adhesion.
Factors Affecting the Acceptance of Mobile Technologies in SMEs: Evidence from Top Management Perspectives
(University of Zielona Góra, 2025) Güntürkün, Barış; Tatlı, Hasan Sadık
Research background and purpose: The research aims to determine the factors affecting the adoption and use of mobile technologies by top managers. The research sample consists of top managers in SMEs. Design/methodology/approach: Data were obtained from SME managers in Turkey. Within the scope of the research, 204 survey data were collected from top managers in SMEs. SmartPLS 3 were used to analyze the data. Findings: It has been determined that factors such as usefulness, social impact, and self-efficacy positively affect the intention to use mobile technologies. In addition, behavioral intention had a significant and strong effect on actual usage. It has been determined that the intention to use mobile technologies has a mediating role in the effect of factors on actual usage for mobile usage, social impact and technology self-efficacy. According to the findings, hedonic and mobile ease of use did not affect the behavioral intention of actual use, either directly or indirectly. Value added and limitations: The research results provide important insights into the factors that are crucial for upper-level SME managers to utilize mobile technologies. The originality of this research lies in its integrated approach, combining the perspectives of top managers of Turkish SMEs with the UTAUT theoretical framework to explain their behavioral intentions toward adopting mobile technologies for business purposes. Therefore, the findings uniquely represent the adoption intentions of SME executives in Turkey.

(Wiley, 2026) Özkurt Kayahan, Zeynep; Özden, Yunus Emre; Çelikyürek Karabağlı, Zeynep; Özyılmaz, Özgün Yusuf; Özer, Füsun; Blatz, Markus B.
Objectives: The aim of the study was to evaluate and compare the effect of thermal aging on the marginal and internal adaptation of veneered and monolithic zirconia (MZ) crowns. Materials and Methods: A maxillary central incisor abutment was digitally designed, fabricated using resin, and scanned for crown design. MZ (IPS e.max ZirCAD Prime Esthetic) and veneered zirconia (VZ; coping: Everest, KaVo; layering: IPS e.max Ceram) crowns were fabricated (n=10). STL files were analyzed in Geomagic Design X to calculate root mean square (RMS) values within the selected marginal and internal regions before and after 10,000, 30,000, and 50,000 thermal cycles with superimposition. Data were analyzed using Shapiro–Wilk and Mann–Whitney U tests. The comparison of thermal aging treatments was evaluated using the Friedman and post hoc Wilcoxon signed-rank tests (p<0.05). Results: Significant differences were found between MZ and VZ crowns (p<0.05). In the MZ group, marginal gaps increased from 104μm (T0) to 115μm (T3), and internal gaps from 122μm (T0) to 146μm (T3). In the VZ group, marginal gaps increased from 82μm (T0) to 128μm (T3) and internal gaps from 136μm (T0) to 204μm (T3). VZ crowns showed higher dimensional changes than MZ crowns. Conclusions: Thermal cycling significantly affected the fit of zirconia crowns. VZ crowns exhibited greater dimensional changes after 30,000 and 50,000 thermal cycles, while MZ crowns maintained superior marginal fit during the same periods. Clinical Significance: This study highlights the influence of thermal aging on the marginal and internal adaptation of veneered and MZ crowns. VZ may be more susceptible to marginal or internal discrepancies after thermal aging, when compared with the MZ.
Individualized respiratory exercise device originated in Türkiye: design, prototype, and first results
(Tubitak Scientific & Technological Research Council, 2026) Cilbir, Çiğdem Emirza; Harputlu, Özge Ertan; Uçgun, Hikmet; Ekşi, Büşra Ülker; Kara, Sarper; Kıyan, Esen
Background/aim: Respiratory muscle training (RMT) and breathing exercises are crucial components in cardiopulmonary rehabilitation. RMT includes inspiratory muscle training (IMT) and expiratory muscle training (EMT); however, existing RMT devices typically support only one of these. Incentive spirometers, which also provide visual feedback for breathing exercises, are frequently used. Achieving an RMT program requires multiple devices, which increases both the cost and complexity of the training regimen. This study aimed to design, calibrate, and test a novel individualized respiratory exercise device that integrates both IMT and EMT functions into a single unit, thereby offering a cost-effective, user-friendly alternative for comprehensive cardiopulmonary rehabilitation. Materials and methods: The design process involved a comparative analysis of existing RMT devices. A concept design was developed, followed by a three-dimensional-printed prototype. Calibration was performed using a pressure meter, with tests conducted on ten healthy volunteers across a range of inspiratory and expiratory pressures. Additionally, a pilot clinical study involving six healthy adults assessed the device’s impact on maximum inspiratory and expiratory pressures (MIP, MEP) and functional exercise capacity during an eight-week RMT period. Results: The internal consistency of the lowest (0.919) and the highest (0.841) levels of inspiration pressure, and of the lowest (0.901) and the highest (0.856) levels of expiration pressure, were highly reliable. Each healthy participant who completed the eight-week RMT program showed increases in MIP, MEP, and six-minute walking distance. Conclusion:The novel respiratory exercise device successfully combines IMT and EMT functions with an incentive spirometer, enabling comprehensive respiratory exercises and RMT within a single unit. Its ease of use and adaptability make it a promising option for both clinical and home-based rehabilitation, potentially improving accessibility and adherence to cardio
Analysis of caesarean section rates according to the Robson classification system and indications for caesarean delivery: experience from a tertiary health centre in Turkey
(BMC, 2026) Düzgüner, Soner; Sağır, Fulya Gökdağlı; Kale, İbrahim; Düzgüner, İpeknur Balin
Background Globally and in Turkey, caesarean section (CS) rates have risen steadily over recent decades, reflecting changes in clinical practice, maternal preference, medico-legal concerns, and healthcare system dynamics. The Robson Ten-Group Classification System, complemented by analysis of CS indications, provides a standardised and objective framework for identifying modifiable factors contributing to the increasing use of CS. This study aimed to evaluate CS rates in a tertiary healthcare centre in Turkey using the Robson classification in conjunction with specific clinical indications. Methods This retrospective observational study included all women who delivered at Umraniye Training and Research Hospital, Department of Obstetrics and Gynaecology, between 01 August 2018 and 11 September 2025. Data were obtained from the hospital’s electronic birth registry and categorised according to the Robson Ten-Group Classification System and indications for CS. Results During the study period, 25,767 births were recorded, of which 11,939 (46.4%) were delivered by CS. The most significant contribution to the overall CS rate originated from Robson Group 5 (23.8%), followed by Group 1 (5.2%). The most common indication for CS was previous uterine surgery, including prior CS and/or myomectomy (54.9%), followed by foetal distress (19.1%). Conclusion The overall CS rate in this study was 46.4%, with Robson Groups 5 and 1 accounting for the majority of procedures (29.0% combined). Previous uterine surgery and foetal distress were the predominant indications.
Dynamic ventilatory responses to submaximal exercise in obese adults
(2025) Yiğit, Şafak; Çılbır, Çiğdem Emirza; Üçgün, Hikmet; Harputlu, Özge Ertan; Ekşi, Büşra Ülker; Aslan, Göksen Kuran; Akıncı, Buket
Background: Obesity increases mechanical stress on the respiratory system, leading to changes in breathing mechanics during physical activity. Aim: The aim of the study was to examine the dynamic ventilatory responses elicited by a submaximal exercise test in obese adults and to compare these responses with those of their non-obese peers. Methods: Twenty-nine obese individuals (32±4/years) without chronic respiratory diseases and 30 non-obese peers (29±3/years) were included in the study. Exercise capacity and dynamic ventilatory responses were assessed using Spiropalm®-equipped six-minute walk test (6MWT). Inspiratory capacity (IC), minute ventilation (VE), and respiratory frequency (RF) were evaluated at rest and post-test. VEpeak and peak breathing reserve (BRpeak) were recorded. Results: The six-minute walking distance of obese participants (479.21±47.16 m) was significantly lower than that of their healthy peers (584.61± 48.42 m) (p<0.001). While there was a significant difference between the groups in the change of VE at baseline and post-6MWT (p=0.017), changes in IC and RF were similar (p>0.05). BRpeak was lower in obese adults (p<0.001), whereas VEpeak was found to be higher in this group (p<0.001). Conclusion: This study shows that obese adults exhibit altered ventilatory responses to submaximal exercise compared to their non-obese peers. Even in the absence of chronic respiratory diseases, these results indicate an increased ventilatory demand which may contribute to exercise intolerance and increased respiratory effort in obesity. These ventilatory adaptations could help inform targeted interventions aimed at improving exercise tolerance and respiratory capacity in this population.
Examining the Relationship Between Social Media Addiction, Fear of Missing Out, Loneliness, and Life Satisfaction Among Youth: A Cross-Sectional Study
(Serbian Psychologists, 2026) Işık, Nurten Arslan; Keleş, Dilsa Azizoğlu; Sandıkçı, İrem Nur; Kotyk, Taras; Okanlı, Ayşe
This cross-sectional study examines the relationships among social media addiction, fear of missing out (FoMO), loneliness, and life satisfaction among young adults. Data were collected from 700 participants aged 18-29 years via an online survey administered between May and June 2024. Validated scales were used to assess key variables: the Bergen Social Media Addiction Scale, the Fear of Missing Out Scale, the UCLA Loneliness Scale, and the Satisfaction with Life Scale. Structural Equation Modeling revealed that life satisfaction was positively associated with loneliness. Social media addiction was strongly associated with FoMO, while FoMO had an indirect negative effect on life satisfaction through social media addiction. These findings shed light on the underlying mechanisms between social media addiction, FoMO, loneliness, and life satisfaction. Such insights can provide significant implications for developing interventions (e.g., digital well-being programs) to help young adults manage their social media use more effectively. Promoting mindful and balanced social media engagement may contribute to enhancing life satisfaction and overall mental well-being.
A Comparative SWOT Analysis of Hospital Management Protocols for Radiation Accidents in Türkiye and Japan
(2025) Kolçak, Dilek
Background: The situation in which radiation emerges uncontrollably is referred to as a radiation accident. Radiation accidents constitute emergencies that can have severe impacts on public health. Therefore, it is of critical importance for hospitals providing healthcare services to be adequately prepared for such incidents. Materials and Methods: This study aims to compare the hospital management protocols for radiation accidents in T & uuml;rkiye and Japan using the strengths, weaknesses, opportunities, threats (SWOT) analysis method. As a country that has experienced a radiation accident, Japan's postincident developments are compared with T & uuml;rkiye's current situation. The study first examines the radiation safety regulations, healthcare policies, and hospital management strategies of both countries. While T & uuml;rkiye has established general protocols under the Hospital Disaster and Emergency Plan (HAP) and for Chemical, Biological, Radiological, and Nuclear (CBRN) incidents, Japan has enhanced its crisis management and emergency response systems following the 2011 Fukushima Nuclear Accident. Within the framework of the SWOT analysis, the strengths and weaknesses of both countries, potential threats, and opportunities for improvement are analyzed in detail. Results and Discussion: This study highlights how T & uuml;rkiye can benefit from Japan's crisis management experience to enhance its preparedness for radiation accidents. The analysis reveals that T & uuml;rkiye has significant shortcomings, particularly in training, drills, and hospital infrastructure. However, its investments in nuclear energy provide opportunities for development through international collaborations. On the other hand, although Japan possesses advanced radiation monitoring systems and extensive experience, it remains under constant threat due to its high concentration of nuclear power plants and exposure to natural disasters. Conclusion: To prevent radiation accidents, it is recommended to develop a hospital management model based on international standards. Additionally, effective intervention strategies should be formulated through the collaborative decision-making of hospital administrators, healthcare professionals, and policymakers to ensure a comprehensive response to radiation accidents.
Linking Extended Business Responsibility to Sustainable Environmental Awareness: Evidence on the Mediating Role of Environmental Values
(Wiley, 2025) Avunduk, Zehra Binnur; Kahveci, Eyüp; Habip, Elif
Eco-conscious businesses are increasingly adopting sustainable materials and improving production efficiency to reduce carbon emissions. These efforts not only minimize waste but also help conserve natural resources. Through extended business responsibility (EBR), firms actively promote sustainable consumption by raising consumer awareness. As awareness grows, purchasing behavior shifts toward environmentally responsible choices, ultimately reducing ecological harm. In contexts where environmental values (EVs) are prominent, social pressure often drives firms toward more sustainable practices. This study addresses a gap in the literature by examining the mediating role of EVs in the relationship between EBR and sustainable environmental awareness (SEA). Based on survey data from 396 participants in Türkiye, partial least squares structural equation modeling (PLS-SEM) was employed for analysis. The findings reveal that EVs partially mediate the relationship between EBR and SEA, serving as a catalyst that enhances the effect of EBR on sustainability awareness. The results provide valuable insights for a wide range of businesses, including manufacturers and e-commerce firms. By aligning with the expectations of environmentally conscious consumers, companies can not only strengthen their sustainability agendas but also gain a sustainable competitive advantage. This study contributes to the literature on sustainable business practices by applying PLS-SEM in the context of an emerging economy and highlighting the critical role of EVs in fostering sustainability awareness.
The Mediating Role of Psychological Empowerment and Trust in Leader on the Effect of Inclusive Leadership on Innovative Work Behavior: A Field Study in the Textile Industry in Turkiye
(Sage Publishing, 2025) Amirli, Hamran; Fettahlioğlu, Ömer Okan; Gül, Necmettin; Tatli, Hasan Sadik
The research is conducted with employees in the textile sector operating in Kahramanmarasx/T€urkiye. The study aims to examine the effect of inclusive leadership on employees’ innovative work behavior, as well as the mediating roles of trust in leader and psychological empowerment in this interaction. This cross-sectional study collected data from 275 employees in the textile industry of Kahramanmarasx/T€urkiye. The data were analyzed by the structural equation modeling (SEM) method using SmartPLS 4 software. The results of the analysis revealed that inclusive leadership has a direct positive effect on IWB. In addition, it was determined that inclusive leadership increases psychological empowerment and trust in leader. While psychological empowerment was found to have a significant mediating role in the relationship between inclusive leadership and innovative work behavior, the mediating role of trust in leader was not supported. The findings suggest that focusing on psychological empowerment in inclusive leadership practices is effective in increasing IWB. The limited effect of trust in leader on innovative work behavior indicates the complexity of leadership and employee interactions. Theoretical and practical implications and recommendations are presented at the end of the study.
Corporate Social Responsibility Campaigns for Behavior Change and the Greenwashing Trend
(Nova Science Publishers, 2025) Cicerali, Eyyüb Ensari
Corporate social responsibility (CSR) concerns the ethical duties in service of society and the environment. Advocating and realizing effective practices for social and natural welfare is its mission. On that note, awakening the society concerning environmental hazards, developing self-transcendental values in people, and addressing sustainability problems such as global warming, deforestation, or resource depletion are its central targets. Organizations can effectively use CSR as a behavior management tool to foster and promote green practices among individuals. Nevertheless, it would be wise to be careful of greenwashing. Greenwashing is the deliberately misleading portrayal of a company or product as more environmentally friendly than it actually is. Tags such as "green," "sustainable," or "organic" are equated with being upscale and pricey; therefore, they can be used as marketing ploys. Thus, to decipher and prevent greenwashing, normative practices such as the development of laws/regulations, the standardization of CSR reports, and the implementation of certification and ecolabeling are currently observable.
