- MakaleYalnız künye2026Scopus SJRQ1A reliability generalization meta-analysis of job insecurity scales: Evidence from hospitality and tourism research
Polat, Eray
The study examines the pooled reliability estimates of job insecurity (JI) scales employed in hospitality and tourism (H&T) research. By synthesizing reported reliability coefficients and identifying moderators influencing score consistency, this meta-analytic study consolidates the fragmented psychometric evidence in the field. Reliability coefficients were derived from 140 independent samples comprising 56,265 respondents. Pooled reliability estimates were calculated separately for each scale, and moderator analyses were performed to explain the variability. Findings indicate that De Witte's (2000) scale is the most frequently utilized scale. Pienaar et al.’s (2013) scale yielded the highest estimate (α=.94, 95% CI [.89.,97]), whereas Hellgren and Sverke's (2003) scale demonstrated the lowest (α=.82, 95% CI [.78.,85]). Moderator analyses revealed that scale version, publication year, number of items, sample size, scale mean, and gender distribution significantly influenced reliability estimates. The study provides robust, context-dependent evidence to inform the selection of JI scales.

Okan, Onur Tolga; Baltaci, Cemalettin
This study compared Sphagnum papillosum, Rhytidiadelphus triquetrus, and Ditrichum gracile in terms of total phenolic content (TPC), total flavonoid content (TFC), antioxidant activities (DPPH, ABTS, ferric reducing antioxidant power [FRAP]), phenolic profiles, fatty acid compositions, and mineral contents. S. papillosum had the highest TPC (986.11 mg GAE/kg) and ABTS activity (9732.14 mg Trolox/kg). R. triquetrus showed the highest TFC (874.01 mg QE/kg) and was rich in protocatechuic (18 803 mg/g) and 4-hydroxybenzoic acids (23.219 mg/g). Although D. gracile had lower antioxidant activity, it contained high lipid (6.71%) and ash (27.66%) levels, along with substantial potassium (73 573.86 mg/kg) and calcium (26 135.94 mg/kg) accumulation. Palmitic acid (C16:0) was the dominant fatty acid in all species. These results demonstrate significant biochemical variation among the studied mosses, underlining their potential as sources of natural antioxidants, bioindicators of environmental stress, and candidates for bioremediation.

Oğuzhan, Hatice; Akay, Gamze; Uzun, Sevda; Koç, Elif Simay; Öncer, Aysun
The aim of this study was to deeply examine the experiences of proxy grief among nurses providing pediatric palliative care. This qualitative phenomenological study was conducted with 16 nurses working in the pediatric ward of a hospital located in the northern region of the country. Data were analyzed using Colaizzi’s phenomenological analysis method. The analysis revealed 3 themes (challenges experienced while caring for children in palliative care; secondary trauma and coping processes; proxy trauma and professional resilience) and 9 sub-themes (emotional strain during care, establishing an empathetic bond, emotional exhaustion, traumatic experiences, seeking psychological support, religious coping methods, developing a professional approach, resilience and acceptance, and motivation to continue in the profession). The study found that nurses providing pediatric palliative care experienced significant psychosocial stress. Pediatric nurses were particularly challenged emotionally when caring for palliative patients. In this context, it is important to develop stress-coping skills to help nurses manage vicarious trauma. Strengthening nurses psychologically and spiritually will positively impact their professional lives, which in turn will enhance the quality of care they provide.

Yuksel, Ferhat; Kaya, Şemsettin
The objective of this study was to develop wheat chips fortified with purple wheat flour (PWF) and to evaluate the effects of PWF incorporation, frying temperature, and frying time on starch fractions, bioactive properties, antioxidant activity, and acrylamide formation. Response Surface Methodology was applied to assess the effects of PWF concentration (0%–100%), frying temperature (170–190 °C), and frying time (40–60 s) on the quality and functional properties of wheat chips. Resistant starch ranged from 0.51 to 0.80 g/100 g and increased slightly with higher PWF levels; this increase was found to be statistically significant. Acrylamide content was found to be a statistically significant parameter (p < .05), showing a decreasing trend from 1,362.68 to 1,082.76 μg/kg with increasing levels of PWF incorporation. Total phenolic, flavonoid, anthocyanin, and antioxidant activities (2,2-diphenyl-1-picrylhydrazyl (DPPH), free radical scavenging capacity (ABTS)) significantly improved with PWF enrichment, whereas ferric reducing antioxidant power showed no notable change. These findings indicate that PWF can be effectively incorporated into deep-fried wheat chips, enhancing their functional and bioactive properties while reducing acrylamide formation.

Çakmak, Seher; Karataş, Hicran
The study aimed to explore the lived experiences of married dialysis patients on the national organ waiting list, focusing on the interplay between illness, familial roles, and societal norms. This research is a qualitative study using semi-structured interviews and participant observation. The study involved 23 marriage-experienced hemodialysis-dependent patients (13 women, 10 men) on the national organ waiting list, recruited between August 16 and November 11, 2022. Data were collected through interviews and observations and were analyzed thematically to identify recurring patterns. Chronic kidney disease (CKD) poses significant physical, psychological, and social burdens, particularly for hemodialysis-dependent patients. Five main themes emerged from this study: (1) When Care Becomes a Test, (2) Dealing with Social Isolation, (3) Sacrifices to Sustain the Marriage, (4) Uninvited voices, (5) Resentful but Thankful. These findings highlight the need for family-centered care that considers diverse family structures and social contexts, while also demonstrating the impact of prolonged hemodialysis (HD) and marital strain on emotional and sexual intimacy.

Serdar, Gönül; Serdaroğlu, Vildan; Keşi̇r, Melek Koç; Kokoç, Memnune; Terzi̇oğlu, Salih
Gold nanoparticles (AuNPs) were synthesized through a microwave-assisted green route using an MAE-derived aqueous Rubus caesius L. fruit extract as a natural reducing and stabilizing medium. The effects of precursor concentration, extract volume, and microwave power were systematically evaluated within the tested experimental range. The combination of 0.075 mM HAuCl₄0.3 H₂O, 0.4 mL fruit extract, and 180 W microwave irradiation produced the most distinct and symmetric surface plasmon resonance response. FT-IR analysis suggested that oxygen-containing functional groups in the extract may have contributed to Au³⁺ reduction and AuNP surface stabilization. TEM analysis revealed spherical, triangular, and hexagonal nanoparticles with an average core size of 11.6 ± 3.2 nm. DLS showed a hydrodynamic diameter of 71.92 ± 4.12 nm and a polydispersity index of 0.425, while the near-neutral zeta potential indicated limited colloidal stability. UV–Vis monitoring showed that the RC-AuNPs largely retained their spectral characteristics for up to 45 days. The synthesized nanoparticles exhibited a core size comparable to previously reported Rubus-mediated AuNPs. The specific contribution of this study is the use of an MAE-derived aqueous R. caesius L. fruit extract together with the systematic evaluation of key synthesis parameters affecting AuNP formation, optical response, and colloidal behavior.

Başoğlu, Mustafa Engin
This study presents a multi-criteria techno-economic evaluation of electric buses (e-buses) equipped with vehicle-integrated photovoltaics (VIPV) to support the global transition toward zero-emission transportation. Aligned with international climate goals like the Paris Agreement and the European Union's 2050 carbon neutrality target, the research assesses ten 12-meter and 18-meter commercial e-bus models from various manufacturers. A computationally efficient methodology is employed, utilizing PVGIS-derived global horizontal irradiation (GHI) data specifically for Gümüşhane, Türkiye. The evaluation framework simultaneously analyzes several critical indicators: PV-based range extension, CO2 emission reduction, grid-connected charging frequency, battery depth of discharge (DoD), and payback period (PP). Findings from the baseline scenario—assuming 50% usable roof area and 22% module efficiency—reveal that e-buses can achieve a daily PV range of up to 19.16 km and annual CO2 emission savings ranging from 1709 to 2596 kg. Additionally, VIPV integration effectively mitigates battery aging by providing a peak DoD reduction of 6.91% and decreases grid-charging dependency by up to 5% during high-irradiance months. In an optimistic scenario featuring 80% usable roof area and 30.1% efficiency, the daily PV range reaches a maximum of 46 km, while the reduction in grid-charging frequency improves significantly to 21.16%. Economic assessments, including Net Present Value (NPV) analysis, confirm the investment's viability, with PPs as short as 3.76 years. This research provides a comprehensive, scalable framework and practical guidance for municipalities and fleet operators to enhance the sustainability of public transport (PT) through solar energy integration.

Demirağ, Hatice; Tuç, Adile
Objective There are no randomized controlled trial (RCT) in the current literature comparing live, robotic, and visual animal-based therapies. This single-blind randomized controlled trial was conducted to comparatively evaluate the effectiveness of live parrot, robotic parrot, and parrot picture therapies on pain during venipuncture in adults with chronic illness. Methods The study included 240 patients randomized into four groups. Groups interacted with live parrots, robotic parrots, or parrot pictures during venipuncture. The control group received no intervention. Pain levels were assessed before and after the procedure using the "Visual Analog Scale (VAS)." Analysis was performed using Chi-Square test, One-way ANOVA and paired samples t-test. Results There was no difference in pre-procedure pain scores between the groups (p ' .05). After the procedure, the VAS score for the live parrot group was 2.01 ± 1.35, for the robotic parrot group 2.03 ± 1.46, for the parrot picture group 2.08 ± 1.62, and for the control group 4.91 ± 1.88. Again, after the procedure, pain scores in all experimental groups were found to be significantly lower than in the control group (p ' .001). Live parrot therapy was found to be the most effective pet therapy, followed by robotic parrot and parrot picture therapy. The reduction in pain in the live parrot group was statistically more significant than in the picture group. Conclusion The research findings revealed that pet therapy applied during venipuncture, especially live animal interaction, may be a potentially effective, safe, and non-pharmacological method for reducing pain. Robotic animals, on the other hand, can be considered a promising alternative when the use of live animals is not possible. It is recommended that these distraction strategies be considered and integration into routine nursing practices be developed as part of patient-centered care.
- MakaleAçık Erişim2026Scopus SJRQ4Modified very deep super resolution network-Gaussian mixture models based single image super-resolution: A comprehensive comparative analysis
Günen, Mehmet Akif
Image Super-Resolution (SISR) is a vital, cost-effective solution for enhancing the spatial resolution of satellite imagery. However, a significant challenge in current SISR techniques is that while deep learning models excel at structural learning, they often struggle to accurately reconstruct intricate high-frequency details and preserve the statistical texture properties of high-resolution images. To address this gap, this paper proposes a novel hybrid method, termed mVDSR-GMM, which leverages the complementary strengths of Gaussian Mixture Models (GMM) and a modified Very Deep Super-Resolution (mVDSR) network. GMM is utilized to model the underlying statistical and probabilistic properties of the image for accurate high-frequency reconstruction while the mVDSR network enhanced with 25 convolutional layers and Leaky ReLU activations boosts the model’s structural feature extraction and non-linear mapping capabilities. This hybrid approach technically integrates the mVDSR and GMM through a parallel merging of their estimated residuals within the luminance channel, thereby enhancing the spatial reconstruction of satellite imagery. The enhanced mVDSR network, with increased depth and Leaky ReLU activation functions, further boosts the model's learning capability and robustness. Through extensive evaluations using satellite imagery datasets and metrics such as PSNR, SSIM, BRISQUE, MSE, UIQI, SAM, and FD, mVDSR-GMM consistently outperformed existing techniques, demonstrating its effectiveness in improving spatial resolution. Experimental results indicate that mVDSR-GMM outperforms main competitors such as SwinIR and SinSR across all evaluation metrics, providing a robust reconstruction performance that is further validated by improved accuracy in the binary separation of urban structures (buildings and roads) from natural environments. The proposed mVDSR-GMM emerges as a promising tool for advancing satellite imagery resolution, with potential applications in remote sensing and geospatial analysis.

Yıldız, Mehmet Berkant; Toğrul, Burçe; Kankal, Murat; Akçay, Fatma; Şan, Murat; Nacar, Sinan
This study diagnoses monthly trends in streamflow magnitude and regime for the Susurluk Basin (Türkiye), which spans semi-arid and mountainous sub-climates. Monthly records from 1990 to 2019 were analyzed at 14 stream gauges and nine precipitation stations. Trends are assessed with the Mann–Kendall (MK) test alongside recent graphical approaches, Improved Visualization for Innovative Trend Analyses (IV-ITA) to resolve value class-based (low/high) behavior, and Innovative Polygon Trend Analysis (IPTA) with the Star Concept to quantify intra-annual transitions. Before the trend analyses, the stations were tested to determine whether their values were homogeneous, and any inhomogeneous stations were excluded from the study. The consistency between the trends of nine precipitation stations and the streamflow data in the basin was analyzed. Across the basin, the average streamflow increased by approximately 40–60% between January and March at many measurement points. However, it then decreased by around 80% in April, albeit at a more moderate rate in December. This suggests significant rebalancing occurred during the December–April period, when most of the annual streamflow occurs. IV-ITA exhibits broadly similar trends for both low and high streamflow classes, with notable exceptions in January–February. Precipitation–streamflow trend directions are largely consistent in the high-flow season (December–April), supporting the notion that climatic control influences the detected shifts. To contextualize these signals, basin-wide land-use/land-cover shifts (1990–2018), notably urban growth, forest expansion, and cropland reconfiguration, provide process context, indicating that a larger fraction of rainfall is routed as fast surface runoff while infiltration and base streamflow recharge decline, alongside seasonally modified water demand. Collectively, the MK+IV-ITA+IPTA framework reveals class-specific and intra-annual dynamics that are obscured by monolithic tests alone and provides decision-relevant evidence for allocation, drought–flood risk, and operations in an intensively managed basin.

Yeniçeri, Esra; Ürkek, Bayram; Şengül, Mustafa
In this study, stirred yogurt was produced using sloe berry powder at different ratios (0, 2, 4, 6, and 8%) and stored for 21 days. The effect of sloe berry powder addition on physicochemical properties was limited, whereas the effect of storage period was more pronounced. Lactic cocci and lactic bacilli counts ranged between 7.78–8.93 log CFU/g and 6.19–9.13 log CFU/g, respectively. Yeast and mold were detected in all samples after 14 days of storage. All color parameters were significantly affected by sloe berry powder addition (p <.001), whereas storage period had no significant effect (p >.05). Total phenolic content and antioxidant capacity increased with increasing levels of sloe berry powder. Only the potassium (K) content was affected by the addition of sloe berry powder. Viscosity and consistency values increased in yogurts containing 6% and 8% sloe berry powder on days 14 and 21 of storage. Sensory scores decreased in all samples at the end of storage. Principal component and correlation analyses indicated that the addition of sloe berry powder and storage period exerted distinct effects on the evaluated parameters. Overall, sloe berry powder can be considered a promising ingredient for the development of nutritional and functional stirred yogurt.

Aydın, Ahmet Serhat; Söyler, Mehmet; Zileli, Raif; Halmatov, Medera; Gürkan, Alper Cenk; Akcan, İbrahim Orkun; Yılmaz, Coşkun
Background: This study aims to examine the effects of game-based and individualized movement training (GBIMT) program on physiological (body weight, body fat percentage, BMI) and motor outcomes (balance, reaction time, motor speed) in young adults diagnosed with autism spectrum disorder (ASD). Methods: An experimental design with pre-test–post-test control groups was used in the study. A total of 20 participants (10 in the experimental group, 10 in the control group) with a mean age of 22.2 ± 4.8 years were monitored for eight weeks. The experimental group participated in GBIMT sessions for 60 min per day, two days per week, while the control group continued their usual educational routines. Body composition (InBody 270 Body Composition Analyzer, model Plus 270, South Korea), balance (TechnoGym, Cesena, Italy), reaction time (BlazePod Ltd., Israel), and motor speed (Computerized Tapping Test, Neurosoft Inc., USA) parameters were used as measurements. Results: Repeated measures ANOVA results indicated a significant reduction in body weight in terms of the experimental group (p = 0.014, η² = 0.289). Large effect sizes were observed for body fat percentage and BMI; however, the group × time interactions were not found to be statistically significant. A significant improvement was observed in the motor speed parameter within the experimental group (p = 0.032, η² = 0.231). Reaction time decreased by 9.8%, although the group × time interaction stayed within the significance limit (p = 0.063). A trend toward improvement was observed in balance parameters; however, no statistically significant difference was found. Conclusion: The findings indicate that GBIMT produced significant improvements in body composition and motor speed after implementing for eight weeks, and also showed a strong tendency to affect reaction time. As a controlled experimental study conducted in Türkiye, this research offers a unique contribution to the literature by demonstrating the effects of game-based and individualized movement programs on both physiological and motor outcomes in individuals with ASD.

This study evaluated the branch, leaf, and fruit extracts of Laurus nobilis collected from Artvin in terms of phenolic composition, antioxidant, antimicrobial, and antidiabetic activities and additionally investigated the binding of selected phenolics to α-amylase/α-glucosidase targets through molecular docking. Using LC–ESI–MS/MS analysis, 31 phenolic compounds were quantitatively identified, with epicatechin, luteolin-7-O-glucoside, and rutin predominating particularly in the branches and leaves. Antioxidant capacity was higher in branches and leaves (total phenolic content [TPC]/FRAP/DPPH IC50: branches and leaves, respectively, 95.27–60.84 mg gallic acid equivalent [GAE]/g, 206.16–162.05 mg Trolox equivalent [TE]/g, and 46.95–113.49 µg/mL). Antimicrobial activity was observed within a minimum inhibitory concentration (MIC) range of 1.25–10 mg/mL; leaves exhibited the strongest effect against Bacillus cereus (1.25 mg/mL), whereas fruits were most effective against Candida albicans (1.25 mg/mL). In antidiabetic evaluation, fruits yielded the lowest IC50 values against α-amylase and α-glucosidase (4.31 and 8.97 mg/mL, respectively), suggesting a “composition-over-quantity” effect despite low total phenolic content. Docking results supported high binding affinities of rutin (α-glucosidase −9.3 kcal/mol; α-amylase −8.1 kcal/mol) and luteolin (−8.6 kcal/mol for both enzymes). Overall, although branches and leaves exhibited strong antioxidant profiles, fruits showed more pronounced inhibitory effects on digestive enzymes; therefore, fractionation studies and in vivo/kinetic validations are recommended.

Çınar, Öznur; Oral, Vildan; Turan, Melikşah; Cengiz, Ekrem
Psychological flexibility is a central construct in Acceptance and Commitment Therapy and an important protective factor for mental health, particularly among individuals expected to function effectively under high stress and uncertainty, such as those in emergency aid and disaster management. Despite its relevance for this population, no Turkish version of the Comprehensive Assessment of Acceptance and Commitment Therapy Processes (CompACT) had been available. The present study aimed to perform a cross-cultural adaptation of the English version of CompACT into Turkish and to evaluate its psychometric properties in emergency aid and disaster management students. The study was conducted in two phases: translation and cross-cultural adaptation, followed by psychometric evaluation in a sample of 302 students. Data were analyzed using SPSS v.21 and AMOS v.22 through exploratory and confirmatory factor analyses, reliability analyses, test-retest analysis, and correlational validity testing. The exploratory factor analysis (EFA) showed that the CompACT consisted of three factors (Openness to Experience, Behavioral Awareness, and Valued Action) explaining 75.848% of the total variance, comprising 20 items. Confirmatory factor analysis (CFA) showed that the three-factor model provided the best fit to the data (χ²/df = 2.590, CFI = 0.963, TLI = 0.956, RMSEA = 0.073). The scale demonstrated satisfactory internal consistency (overall alpha = 0.843) and temporal stability (test-retest r > 0.70 across all subscales), and its expected negative associations with the Acceptance and Action Questionnaire-II (r = −0.365) and the Depression Anxiety Stress Scales-21 (r = −0.403) supported its criterion-related validity.

Purpose – The aim of the paper titled “Development of a hybrid technique for solving the Newell–Whitehead–Segel (NWS) equation using the Caputo-Fabrizio derivative” is to develop a new numerical method for solving the NWS equation using the Caputo-Fabrizio fractional derivative. This method involves the combination of the Caputo-Fabrizio Elzaki transformation and the q-homotopy analysis transformation method. The study aims to analyze the NWS equation that models the reaction-diffusion dynamics in biological and chemical systems. The convergence analysis of the proposed method is performed, and the obtained solutions are visualized with two- and three-dimensional graphics using the Maple software. The results show that the proposed method is more powerful and effective than the existing methods. Design/methodology/approach – In this study, a hybrid analytical-numerical method is developed to solve the NWS equation formulated using the Caputo-Fabrizio fractional derivative. The method is a combination of: q-homotopy analysis method (q-HATM) and Shehu transformation technique (ST). By combining these two powerful methods, a solution approach that does not require linearization or complex calculations for nonlinear fractional partial differential equations, converges quickly and gives high accuracy results, is presented. The obtained solutions are tested for numerical accuracy and are supported graphically. Findings – In the article titled “Development of a hybrid technique for solving the Newell–Whitehead–Segel equation using the Caputo–Fabrizio derivative”, the authors propose a new hybrid method for solving the time-fractional NWS equation. This method is a combination of the q-HATM and the ST. The proposed q-HSATM provides an efficient and lightweight approach for solving nonlinear fractional partial differential equations without requiring linearization, discretization or complex polynomials. This hybrid technique obtains the approximate analytical solution of the NWS equation using the Caputo–Fabrizio derivative. The method provides fast convergence and high accuracy with less memory and processing power requirements. It also stands out as a reliable tool for modeling complex systems in applied sciences such as physics, biology and engineering. In conclusion, this study provides an effective and applicable method for solving nonlinear differential equations formulated with the Caputo-Fabrizio derivative, making a significant contribution to the field of fractional calculus. Originality/value – This section of the article titled “Development of a hybrid technique for solving the Newell-Whitehead-Segel equation using the Caputo-Fabrizio derivative” can be summarized as follows: This study is one of the first hybrid q-HATM and ST-based methods developed to solve the NWS equation using the Caputo-Fabrizio fractional derivative operator. Its unique aspects: Unlike traditional methods, it provides models more suitable for physical systems by working with the Caputo-Fabrizio derivative, which includes the memory effect and whose kernel function is not exponential. The presented method presents a new and powerful analytical-numerical technique that can produce approximate solutions with high accuracy without requiring linearization or discretization. The developed technique is valuable not only theoretically but also with its applicability to reaction-diffusion systems in applied sciences.

Ayaydın, Hasan; Ergün, Tolga; Ergün, Hilal Ok; Barut, Abdulkadir; Pilatin, Abdulmuttalip
This study examines the relationships among military spending, renewable energy (RNW), globalisation, economic growth, and ecological footprint in 35 OECD member countries, using data covering 1990–2022. Specifically, this study contributes to this discussion by presenting empirical evidence on the link between military expenditure and ecological footprint, while accounting for the moderating role of RNW in OECD countries. The analysis utilised Kao, Pedroni, and Westerlund cointegration tests, Driscoll-Kraay robust standard error tests, Dumitrescu-Hurlin causality tests, and FMOLS and DOLS techniques for robustness verification. Empirical results show that military spending in OECD countries increases the ecological footprint, leading to environmental degradation. Furthermore, the combined effect of military expenditure and RNW reduces the ecological footprint and contributes to environmental sustainability. The results contribute to the existing literature by underlining the role RNW plays in reducing the ecological footprint of military expenditures and by offering policy recommendations for environmental sustainability. From a managerial and policy perspective, the findings suggest that defense-related institutions and policymakers should integrate environmental sustainability criteria into military planning and procurement strategies. Increasing the use of renewable energy in military infrastructure, logistics, and defense technologies may significantly reduce the ecological footprint associated with military expenditure. Therefore, the transition toward renewable energy supported defense systems can serve as a strategic tool for aligning national security objectives with sustainable development goals.
