Aydin, Aydanur; Bağcivan, Gülcan; Özkan, Aleyna
Background: Despite its growing presence in healthcare settings, research on the effectiveness of virtual reality (VR) interventions for symptom experience of patients with cancer remains varied and requires a comprehensive synthesis to reach definitive conclusions. Objective: This systematic review and meta-analysis aimed to assess the effectiveness of VR interventions in managing anxiety among individuals diagnosed with cancer. Methods: A comprehensive search of Ovid MEDLINE, PubMed, CINAHL, Web of Science, and Scopus databases was conducted for studies published from 2000 to November 2025. Publications were evaluated by independent reviewers for inclusion. The methodological quality of the included studies was assessed via Joanna Briggs Institute (JBI) critical appraisal tools for randomized controlled trials and quasi-experimental studies. Results: Twenty-one publications satisfied the requirements for review inclusion. The meta-analysis demonstrated that VR-based interventions were significantly effective in the management of patients’ anxiety, yielding a moderate-to-high effect size (SMD = −0.793, 95% CI = −1.403 to −0.184; Z = −2.551; p = 0.011). Most studies reported statistically significant decreases in anxiety scores across various cancer types, including breast, prostate, and ovarian cancers. No major side effects were reported, although minor instances of cyber sickness were managed by adjusting session durations. User satisfaction was exceptionally high, with satisfaction scores reaching 4.47/5 and 7.35/10. Implications for practice: The results support the use of VR as an effective and safe non-pharmacological intervention for anxiety management. The findings highlight the potential for VR to be integrated into routine oncology nursing and palliative care to improve the patient experience during stressful treatments like chemotherapy. Conclusion: VR-based interventions are an effective, safe, and highly acceptable approach for managing anxiety in patients with cancer. Further research is needed to support wider clinical implementation and to investigate the potential benefits of VR for other physical and psychological symptoms over longer follow-up periods.

- MakaleAçık Erişim2026Scopus SJRQ1The mediating role of attitudes in the effect of human and environment-centered value orientation on green cosmetic product purchasing behavior: comparison of different countries
Baltacı, Duygu Çinar; Durmaz, Yakup; Baltacı, Furkan
The growing concern for environmental issues has reached a critical level, demanding immediate attention. With the widespread integration of cosmetic products into daily routines, the escalating environmental impact cannot be ignored. Consumers are increasingly scrutinizing the environmental footprint of their purchases and the practices of manufacturing companies. To maintain their competitive edge, businesses must proactively understand and address the evolving needs and expectations of their consumers. This study aims to reveal the relationships between consumers’ environmental values, attitudes toward green products, and green cosmetics purchasing behaviors to guide decision-makers in the cosmetics industry. In addition, the study also evaluated the impact of consumers’ cultural backgrounds on their attitudes toward green products and their purchasing behaviors in the green cosmetics sector. We conducted a comprehensive online survey by collecting primary data from 883 respondents from 10 countries in Asia and Europe. Our analysis used partial least squares (PLS) with SMART PLS to comprehensively examine the interrelationships between variables. An ecocentric orientation positively influences attitudes and purchasing behavior toward green cosmetic products, while an anthropocentric orientation has a negative effect. Additionally, consumers’ attitudes mediate the impact of environmental attitudes on purchasing behavior and counteract the negative effect of anthropocentric attitudes. Cultural differences significantly impact consumers’ attitudes and purchasing behavior for green cosmetics. The study’s findings offer valuable insights for cosmetic companies dealing with growing demand for cosmetic products and environmental awareness. The empirical support for existing literature is significant, and the study’s structural model enriches the green cosmetics literature. It’s essential to consider both consumers and producers for sustainable green cosmetic production, ensuring profitability and encouragement for producers.

İncele - MakaleYalnız künye2026Scopus SJRQ2Monthly precipitation trends in Türkiye under complex topography and varying climate: a seasonal Mann–Kendall and innovative polygon trend framework
Şan, Murat; Nacar, Sinan; Kankal, Murat
The impacts of climate change are increasingly sensible, and Türkiye with its varied topography and diverse climate types is particularly exposed to these shifts. Understanding how precipitation patterns are evolving across its regions is therefore critical. While trend analysis is a widely used tool for this purpose, conventional approaches overlook periodicity, limiting their practical value for water resource management and irrigated agriculture. Therefore, this study aims to examine seasonal trends in long-term (1969–2020) monthly total precipitation in Türkiye, in which each calendar month is treated as a separate season in the sense of seasonal trend-analysis terminology, accounting for altitude, slope, geographical region, and Köppen climate classification. For this purpose, the seasonal Mann-Kendall (SMK) test and the innovative polygon trend Wilcoxon significance test (IPWST), a relatively new graphical method, were used, and the two approaches were comparatively evaluated. According to the study’s results, the rate of increase in coastal areas, specifically the Aegean and Black Seas, exceeds the rate of decrease. In contrast, the reverse is observed in inland and eastern regions. The IPTWST method indicates a more pronounced increasing trend in the Marmara and Mediterranean regions. Furthermore, although analogous trends are observed at lower slopes and altitudes, analyses indicate that these trends are more strongly related to altitude, with the rate of increase decreasing as altitude increases. The IPTWST identified significant or weak trend signals at a larger number of stations than the SMK, particularly in relation to altitude. Nationwide, the two methods revealed significant increases of 7% and decreases of 6%, respectively; this pattern was supported by statistical tests, reflecting the variability of regional climates and the influence of topographic factors on trend analysis.

Kurt, Pınar
Mediostoma izmiricum Snegovaya, Kurt and Yağmur, is a species of the family Nemastomatidae Simon, and is endemic to Türkiye. To date, there is no molecular data available for the 16S rRNA gene region for this species or its genus, which limits our knowledge of its phylogenetic position. The 16S rRNA gene region of this species was analysed for the first time, yielding a sequence length of 465 bp. Bayesian inference (BI) and maximum likelihood (ML) phylogenetic trees were subsequently constructed based on these data, revealing the phylogenetic position of both the species and its genus.

Aktaş, Esra; Atmaca, Hatice Ediz
Despite technological developments and increasing awareness in the field of occupational health and safety, occupational accidents remain one of the fundamental problems that continue to have significant economic and social consequences. Particularly in the manufacturing sector, the diversity of production processes, differences in the machinery and equipment used, and the complexity of working environments cause occupational accidents to exhibit risk patterns that are both shared across sectors and specific to individual sectors. In this context, this study conducted a topic modeling analysis using the BERTopic algorithm on 1,600,000 occupational accident narratives to identify sector-specific risk patterns and error types associated with 24 different economic activities within the manufacturing sector. To improve topic modeling performance, a multilingual SentenceBERT-based embedding model and a Turkish-specific tr-MTEB embedding model were compared, and the analysis was carried out using the model that provided higher representational capacity and better topic separation performance for the occupational accident narratives. The findings show that, although the sectors differ in terms of production structure, types of machinery and equipment used, material characteristics, and working environments, occupational accidents largely cluster around similar risk mechanisms. As a result, it was determined that the BERTopic method makes the sectoral risk patterns embedded in occupational accident narratives more visible and provides an analytical basis for developing sector-specific prevention strategies in occupational safety practices.

Tuncer, Metin; Özalp, Cemal; Keskin, Azra
Background: Maintaining privacy in intensive care units (ICUs) is challenging because of high workload, invasive procedures, continuous monitoring and shared care environments. Patients with impaired consciousness may be particularly vulnerable because their ability to express privacy preferences, assert personal boundaries and advocate for themselves is limited. Aim: To explore intensive care nurses' experiences of protecting privacy when caring for patients with impaired consciousness. Study Design: A descriptive qualitative study was conducted with 20 intensive care nurses in Türkiye between March and April 2026. Data were collected through semi-structured online interviews and analysed using inductive thematic analysis. The study was reported in accordance with the Consolidated Criteria for Reporting Qualitative Research guidelines. Findings: Four themes were identified: the marginalisation of privacy under clinical priorities; structural and process-related constraints on privacy in intensive care; loss of subjectivity and the mechanisation of care in patients with impaired consciousness; and ethical and psychosocial implications of privacy violations. Conclusions: Privacy in intensive care is shaped not only by individual ethical awareness but also by workload, environmental conditions, care routines and communication practices. Patients with impaired consciousness have the same rights to privacy and dignity as other patients; however, their reduced ability to express preferences, assert personal boundaries and advocate for themselves may make privacy violations less visible and increase their dependence on nurses for protection. Relevance to Clinical Practice: Protecting the privacy of patients with impaired consciousness in ICUs requires structured care routines, standardised bedside communication, minimisation of unnecessary exposure during procedures and targeted ethical awareness training to support dignity in everyday practice.
- MakaleAçık Erişim2026Scopus SJRQ1The past scene of hospitality ethics: A citation analysis perspective
Polat, Eray; Köseoglu, Mehmet Ali
The literature on ethics research in hospitality has significantly expanded in recent years. The objective of this study is to present a comprehensive overview of ethical research in the field of hospitality literature. This will facilitate insight into future developments by examining the past. A two-step approach is employed, comprising citation analysis, a bibliometric analysis technique, and a systematic review. The former is used to identify themes, which are then discussed in the latter. The citation analysis revealed five main themes of the domain: environmental concerns, organisational citizenship behaviour, reputation management and ethical leadership. Environmental concerns were examined from two perspectives: the viewpoint of hotels and the environmental behaviours of tourists and consumers. Subsequently, a systematic review was conducted using the TCM framework (theory/context/methodology) with the objective of identifying the most prominent theories, contexts, and methodological issues associated with each theme. The issue has predominantly been discussed using quantitative analysis and social-based theories. Research has been mainly conducted in the US and the EU. Environmental ethics is likely to remain a significant area of concern in the future. This study offers a perspective that can aid researchers in developing future studies on ethics and help practitioners enhance the ethical climate of the industry.

Uysal, Turan; Kaya, Selim
This study investigates the gamma-ray and neutron shielding performance of advanced ceramic composites containing colemanite, pyrophyllite, and plastic clay as environmentally friendly alternatives to conventional lead-based shielding materials. Gamma-ray attenuation properties were evaluated over the energy range of 59.54–2000 keV using theoretical calculations from WinXCOM and Monte Carlo simulations performed with the EGS4 code. Excellent agreement between the two methods confirmed the reliability of the simulation results. The mass attenuation coefficient (μ/ρ) decreased with increasing photon energy due to the transition from photoelectric absorption to Compton scattering and pair production mechanisms. Correspondingly, the half-value layer (HVL) and mean free path (MFP) increased, while radiation protection efficiency (RPE) decreased with photon energy. The effective atomic number (Zeff) exhibited an energy-dependent decline, reflecting changes in dominant photon–matter interaction processes. Neutron shielding performance improved with increasing colemanite content owing to the presence of boron-rich phases, and Sample-5 exhibited the highest fast neutron removal cross-section (ΣR = 0.11062 cm−1). The same sample also showed the highest gamma-ray kerma coefficients, indicating enhanced energy absorption capability. Overall, the results demonstrate that colemanite-enriched ceramic composites provide effective combined gamma-ray and neutron shielding and represent promising, sustainable, and non-toxic alternatives for radiation protection applications.
- MakaleAçık Erişim2026Scopus SJRQ1Match success in football: insights from raw and possession-normalized key performance indicators in the Turkish professional league
Sever, Ozan; Öncü, Çağdaş; Öztaşyonar, Yunus; Aksoy, Ömer; Bayrakdaroğlu, Serdar
Background: Match-performance indicators are widely used to explain success in football; however, traditional analyses based solely on absolute key performance indicators (KPIs) may overlook contextual factors such as ball possession and phase of play. This study aimed to examine match-performance indicators associated with winning in Turkish professional football using two complementary approaches: a raw KPI model based on absolute match actions and a possession- and phase-of-play–normalized KPI model accounting for contextual opportunity. Methodology: Match data were obtained from a validated event-based database covering six consecutive seasons, yielding 2,728 team observations from 1,364 win–loss matches. Descriptive comparisons between winning and losing teams were conducted, followed by multivariate binary logistic regression analyses to identify performance indicators independently associated with match success under both modeling approaches. Results: At the descriptive level, winning teams demonstrated higher values for shots, shots on target, accurate passes, opponent-half accurate passes, accurate crosses (%), and opponent-half accurate passes (%), whereas total possession and total passes did not differ significantly between groups. In terms of disciplinary indicators, losing teams received significantly more yellow and red cards, whereas fouls committed were significantly higher in winning teams (p = 0.014). However, the normalized indicator (fouls committed per out-of-possession) did not differ significantly between groups. In the raw KPI model, positive predictors of match success included shots on target (OR = 1.58), accurate crosses (OR = 1.10), opponent-half accurate passes (OR = 1.01), and fouls committed (OR = 1.04). Negative predictors were total crosses (OR = 0.92), yellow cards (OR = 0.89), and red cards (OR = 0.49). In the possession-normalized model, significant positive predictors were shots on target per possession, accurate crosses per possession, and fouls committed per out-of-possession. Significant negative predictors included crosses per possession, accurate crosses (%), yellow cards per out-of-possession, and red cards per out-of-possession. Conclusions: The findings indicate that combining absolute performance indicators with context-sensitive normalized metrics may provide a more comprehensive perspective on match success in football. Offensive efficiency and disciplinary control emerged as key correlates of winning, particularly when evaluated relative to possession and phase-of-play contexts. These findings suggest the potential value of integrating contextualized performance analysis into match evaluation and performance analysis frameworks.

Bozkır, İsa; İbişoğlu, Merve Seda; Kayıkçıoğlu Bozkır, İlknur; Güler, Halil İbrahim
The discovery of dual acetylcholinesterase (AChE) and β-secretase (BACE1) inhibitors remains a promising strategy against multifactorial Alzheimer’s disease. Here, rigorously curated ChEMBL-derived data were used to develop explainable QSAR (Quantitative structure–activity relationship) models for dual-inhibition prioritization. Molecules were standardized, near-duplicates were removed using a Tanimoto similarity threshold (≥ 0.80), and physicochemical outliers were filtered prior to modeling. Multiple classifiers (including Light Gradient-Boosting Machine, eXtreme Gradient Boosting, Random Forest, Support Vector Machine, k-Nearest Neighbors and Gradient Boosting Decision Trees) and fingerprints (e.g., RDKit fingerprints, Extended Connectivity Fingerprint) were benchmarked under scaffold-based nested cross-validation to prevent data leakage. Class imbalance was handled with SMOTETomek applied strictly within training folds. Model selection relied on F-Score, Area Under the Precision–Recall Curve, Matthews Correlation Coefficient (MCC), and Recall, and performance was accompanied by bootstrap confidence intervals, calibration curves, and Y-randomization controls. In classification, the top model (GBDT + ECFP6) achieved strong generalization (Recall ≈ 1.00, PR-AUC ≈ 0.84, MCC ≈ 0.81, F1 Score ≈ 0.84). Shapley Additive Explanations (SHAP) analysis highlighted aromatic and hydrogen-bonding substructures as key positive contributors. Prospective candidates (e.g., CHEMBL5082250, CHEMBL1651126, CHEMBL1651127) were evaluated by active-site-focused docking against AChE (PDB: 4EY7) and BACE1 (PDB: 2G94) with essential waters retained; docking scores (ΔG, kcal·mol⁻1) were used for relative ranking of the ligands. SwissADME/pkCSM profiling suggested CNS-relevant properties (e.g., MPO, logBB, P-gp liability) and acceptable oral drug-likeness. Collectively, the workflow provides a reproducible and transparent pipeline for prioritizing dual AChE/BACE1 chemotypes and nominates testable scaffolds for experimental validation.

Kıranşan, Murat
This study reports the sonocatalytic degradation of malachite green (MG) in media using synthesized Co3O4 nanoparticles and a CTAB-modified zeolite supported Co3O4 hybrid nanocatalyst (M-ZLT@Co3O4). The catalysts were characterized by XRD, FT-IR, SEM-EDX, TEM, XRF, N2 adsorption–desorption, BET, and BJH analyses, verifying crystalline Co3O4 formation, successful immobilization on the modified zeolite support, porous architecture, morphology and elemental distribution. Under optimized conditions of 1 g L−1 catalyst dosage, 20 mg L−1 MG concentration, natural pH, and 300 W L−1 ultrasonic power, M-ZLT@Co3O4 achieved 99.31% ± 0.45% degradation within 120 min. Decreasing the MG concentration to 5 mg L−1 increased the efficiency to 99.96% ± 0.64%, confirming high activity at low pollutant loading. The degradation followed pseudo-first-order kinetics, with kapp values of 0.0042–0.0595 min−1 depending on catalyst dosage, 0.0046–0.0667 min−1 for initial MG concentration, and 0.0117–0.0620 min−1 under pH conditions. Water matrix inhibition followed distilled water (99.31%) > tap water (96.08%) > river water (88.84%) > lake water (86.90%), whereas higher ultrasonic power increased degradation from 91.98% at 200 W L−1 to 99.90% at 500 W L−1. Dye degradation followed MG (99.31%) > CR (95.78%) > BY2 (92.15%) > MV (90.24%) > AO7 (85.62%) > RB19 (82.49%). Comparative tests demonstrated performance for US/M-ZLT@Co3O4 (99.31%) compared with US/Co3O4 nanoparticles (78.48%), US/ZLT (72.86%), and US/MG alone (35.71%). The best activity was obtained at 0.8–2 g L−1 catalyst dosage and 5–20 mg L−1 MG concentration, while reusability tests showed a decrease from 99.31% to 78.82% after six cycles, indicating promising stability.

Gücer, Mehmet Ali; Çimen, Okay; Aktağ, Alican; Keskin, Serdar
The growing demand for critical minerals driven by the global energy transition and advanced technologies highlights the importance of unconventional metal reservoirs. This study investigates the Ni-, Co-, V-, and Pt-enriched Dilli manganese deposit (Kemaliye-Erzincan, Eastern Türkiye) to constrain the mineralogical, geochemical, and genetic controls on critical metal enrichment in Mn oxide mineralization. An integrated approach combining field observations, petrography, X-ray diffraction (XRD), whole-rock geochemistry, mineral chemistry, and stable C-O isotope analysis was applied to better understand the potential origin of critical mineral enrichments. The mineralization is dominated by Mn4+-bearing oxides, principally pyrolusite and hollandite, accompanied by minor rhodochrosite. High MnO (39-64 wt%) and very low Al2O3 and Fe2O3 contents indicate chemical precipitation with negligible detrital input. Discrimination diagrams and trace-element systematics consistently support a structurally controlled hydrothermal origin. Chondrite-normalized REE patterns display low total REE and very low Nd contents comparable to typical hydrothermal deposits, whereas neutral to slightly positive Ce anomalies and non-chondritic Y/Ho ratios suggest limited oxidative interaction with surface-derived fluids rather than primary marine hydrogenetic growth. Stable C–O isotope compositions of co-genetic calcite are inconsistent with a purely marine depositional environment and indicate precipitation from low-to moderate-temperature hydrothermal fluids. Mineral chemistry reveals strong phase-specific partitioning: hollandite preferentially incorporates V and Ba, whereas pyrolusite is enriched in Ni. Cobalt occurs in both phases, whereas Pt may also be present in both Mn oxide phases, suggesting that trace-element distribution is influenced by both crystallochemical and physicochemical controls. The enrichment of Ni, Co, and Pt is most plausibly linked to hydrothermal fluid circulation through ultramafic units, which likely acted as the primary metal source prior to precipitation. The Dilli deposit thus represents a structurally controlled hydrothermal Mn system enriched in critical metals, emphasizing the exploration relevance of Mn oxide mineral chemistry in identifying alternative sources of critical metals in Türkiye.

Özalp, Cemal; Gerçek, Abdullah; Tuncer, Metin
Aim: This study aimed to adapt the Reasons for Implicit Rationing of Nursing Care Scale into Turkish and evaluate its validity, reliability and measurement invariance among nurses in Türkiye. Background: Implicit rationing of nursing care may compromise care quality and patient safety and is influenced by organizational, resource-related and communication factors. A culturally valid instrument is needed to identify the factors contributing to implicit rationing of nursing care within the Turkish healthcare context. Design: A methodological, cross-sectional psychometric validation study. Method: Data were collected between July and December 2025 from nurses working in a public hospital in Türkiye. The source population comprised 900 nurses and 411 nurses were included in the final sample using convenience sampling. Data were collected using the Personal Information Form and the Reasons for Implicit Rationing of Nursing Care Scale. Construct validity was examined using exploratory and confirmatory factor analyses on randomly divided samples. Convergent and discriminant validity and gender-based measurement invariance were assessed. Reliability was evaluated using Cronbach's alpha, McDonald's omega and the intraclass correlation coefficient. Results: The Kaiser–Meyer–Olkin value was 0.936, indicating that the data were suitable for factor analysis. Exploratory factor analysis revealed a two-factor structure consistent with the original scale, explaining 74.30% of the total variance. Confirmatory factor analysis demonstrated acceptable model fit. Convergent validity was supported, whereas the heterotrait–monotrait ratio value indicated borderline discriminant validity. Measurement invariance across genders was largely supported at the configural, metric and scalar levels. The scale demonstrated high internal consistency and temporal stability, with a Cronbach's alpha value of 0.941, a McDonald's omega value of 0.932 and an intraclass correlation coefficient value of 0.873. Conclusion: The Turkish version of the Reasons for Implicit Rationing of Nursing Care Scale is a valid, reliable and gender-invariant instrument. It can be confidently used in Turkish clinical settings to assess factors contributing to implicit rationing of nursing care.

Kömürcüoğlu, Ömer Faruk; Kömürcüoğlu, Elif Duygu; Hayaloğlu, Pınar
Climate change is a global risk reshaping tourism through destination attractiveness, service continuity, and travel risk perception. Yet tourism research has largely focused on traditional determinants such as income, price competition, and global integration, while multidimensional evidence on climate impacts remains limited. This study examines the link between climate change and tourism inbound expenditure in 12 leading tourism economies over 2004–2019. Climate change is measured using a PCA-based index combining per capita CO2 emissions with temperature and precipitation volatility. This approach captures both average climate conditions and fluctuations in the climate regime. MMQR is employed to account for heterogeneous effects, with economic size, exchange rate, and globalization included as controls. Results show that increases in the climate change index significantly reduce tourism inbound expenditure. Robustness is confirmed by PCSE and FGLS estimators, while causal linkages are assessed using the HPJ test. By showing that multidimensional climate pressure constrains the expenditure performance of major tourism economies, the study extends the application of destination resilience theory to a macroeconomic setting. It also highlights the need to integrate climate adaptation, resilient infrastructure, and ecosystem protection into sustainable tourism planning.

Bingöl, Nuray; Aktepe Coşar, Dilan; İşcan Ayyıldız, Neşe
Objective: Individuals with epilepsy often face challenges with medication adherence and health monitoring because communication difficulties that hinder self-expression and information exchange, thereby complicating effective disease management. This study aimed to examine the health communication problems experienced by individuals with epilepsy. Methods: This descriptive, cross-sectional study was conducted among 172 individuals with epilepsy who presented to the neurology outpatient clinic in eastern and northern Türkiye between August 2023 and August 2024. Study data were collected using the descriptive data form and the health communication problems scale. The independent groups t-test, one-way ANOVA, and Tukey test were used to evaluate the data. Results: On the health communication problems scale, individuals with epilepsy had mean scores of 2.41 ± 0.53 for the effective communication problems sub-dimension, 2.88 ± 0.80 for the social communication problems sub-dimension, and 2.68 ± 0.72 for the communication barriers sub-dimension. No significant differences were detected in the mean scores for health communication problems among individuals with epilepsy by sex, health expenditure, seizure type, or seizure characteristics (p > 0.05). Conclusion: The study revealed that individuals with epilepsy experienced moderate difficulty with health communication. Those who were married, had higher educational attainment, were unemployed, had lower income levels, and were receiving polytherapy experienced greater communication challenges with healthcare professionals.

Aim: This study aimed to assess the lived experiences of adolescent pregnant young women, with a specific focus on the psychosocial aspect of adolescent pregnancy, using a phenomenological approach. Design: Employing the phenomenological research method, semi-structured in-depth interviews were conducted between 3 August and 18 August 2023 with 15 young women (mean age = 21.86 years; SD = 1.06) living in a province in eastern Turkey who had undergone adolescent pregnancy 3–5 years before. Methods: The criterion sampling method, a form of purposive sampling, was used to form the sample group. Interviews were carried out until data saturation was reached. All interviews were recorded and transcribed, and thematic analysis was utilised to analyse the data. The study adhered to the COREQ checklist for reporting. Results: Through data analysis, three main categories (reflections on adolescent pregnancy, challenges due to adolescent pregnancy, and effects of adolescent pregnancy) and nine sub-themes (emotions, roles and responsibilities, perception of social support, cognitive, emotional, behavioural, mental, physical, and social) emerged. Conclusion: Our study highlights the adverse psychosocial impact of adolescent pregnancy on young women. Young women who got married at an early age before attaining full physical, social, and psychological maturity grappled with the substantial burdens of adolescent pregnancy and adjusting to their new roles. The study’s implications are significant, emphasising the necessity of addressing the psychosocial facets of adolescent marriage and pregnancy, and gaining valuable insights for the future.

Then, besides basic set-theoretical operations and the score function, a new distance measure is also presented. Furthermore, a decision method integrating with regret theory is proposed. Additionally, to compute the weights of criteria under bipolar Z-number information, a method in which objective and subjective criterion weights are considered simultaneously is introduced by combining the weights found by SWARA and MEREC. Also, a model with standard deviation is developed to obtain decision maker’s weights. Finally, the problem of selection of paper raw material is handled to demonstrate stability and advantage of the proposed method.

Beken, Hikmet Gülçin; Kirer Silva Lecuna, Hale
This study investigates how fertility, family structures, and institutional environments shape women’s labor force participation in Southern Europe (Greece, Italy, Spain, Portugal) and Türkiye. Using balanced panel data from 2015 to 2022 and fixed effects models with Driscoll–Kraay standard errors, the analysis identifies a negative relationship between fertility and female employment, though only at marginal levels of statistical significance. Robustness checks using Ridge regression and principal component analysis confirm this finding across alternative specifications. Significant country-level fixed effects reveal considerable heterogeneity, with Portugal and Spain exhibiting higher baseline participation rates and Türkiye recording notably lower values. While the empirical model does not directly measure institutional support, childcare availability, or cultural norms, the comparative literature suggests that cross-country differences in these dimensions likely contribute to the observed patterns. The findings point to the potential importance of integrated policy approaches, including affordable childcare and flexible work arrangements, in supporting women’s employment alongside fertility.

Hierarchical multiple regression analyses were used to assess the additional impacts of weight-related stigma and eating attitudes on body appreciation, while adjusting for demographic and anthropometric factors. Results: Weight self-stigma, particularly the internalization of weight bias, showed a significant negative association with body appreciation. Weight self-stigma and its subdimensions (self-devaluation and fear of enacted stigma) had substantial negative correlations with body appreciation. These correlations encompassed the subdimensions of body appreciation, specifically general body appreciation and body image investment. While eating attitudes did not show a significant correlation with body appreciation at the bivariate level, they became a significant predictor in the hierarchical regression model, suggesting a conditional (suppression) effect after accounting for weight-related stigma and BMI. Conclusion: The findings emphasize the important function of weight-related stigma in diminishing body appreciation among young adults and stress the necessity of examining eating attitudes in conjunction with stigma-related factors. Interventions designed to enhance positive body image should focus on both internalized weight stigma and maladaptive eating-related attitudes.

Okan, Serdar
This research examines the mediating role of perceived value in the relationship between brand equity and passenger loyalty, focusing on Turkish Airlines. Data were gathered from 569 passengers of Turkish Airlines and were analyzed by using EFA in SPSS and CFA in SmartPLS. The results indicate that brand equity significantly has an indirect impact on passenger loyalty (β = 0.112, P = 0.011). In addition, although brand equity has a positive effect on perceived value (β = 0.240, P < 0.001), perceived value also has a positive effect on loyalty (β = 0.493, P < 0.001). The results also indicate that perceived value partially mediates the effect of brand equity on loyalty (β = 0.118, P < 0.001). Such findings imply that post-flight communication with the company, passengers’ feedback opportunities and efficient service problem resolution might result in an increase of perceived value fostering customer loyalty. There appears to be a significant underestimation of the importance of the direct effect and of its impact on the indirect effects of brand equity. This study bridges the research gap by analyzing perceived value as a mediator between brand equity and loyalty, focusing on Turkish Airlines.
