Lyu, Guanjie; Ouimet, Frédéric; Susam, Selim O.
This paper studies a Bernstein-smoothed plug-in estimator for the lower-tail Spearman's rho curve, a rank-based measure of local concordance defined through a normalized copula integral over the lower-left square (Formula presented.). The estimator applies the lower-tail Spearman functional to the empirical Bernstein copula and introduces a degree parameter that controls finite-sample regularization. The contribution is target-specific estimation and inference for the lower-tail Spearman's rho curve rather than a new general-purpose copula estimator. We establish uniform strong consistency on compact intervals away from zero whenever (Formula presented.). Under a target-specific integrated Bernstein-bias condition and (Formula presented.), we derive functional weak convergence with the same first-order Gaussian limit as the empirical copula-based estimator; this degree regime includes (Formula presented.). For inference, we justify a smoothed beta bootstrap based on sampling from the empirical beta copula and construct pointwise confidence intervals from the absolute centred bootstrap root. Monte Carlo experiments for the Farlie–Gumbel–Morgenstern, Gaussian, Clayton, and Frank copulas assess pointwise coverage over the threshold grid and show that Bernstein smoothing generally reduces integrated variance and often lowers mean integrated squared error under weak to moderate dependence. Additional common-sample experiments compare the proposed estimator with the empirical beta and empirical checkerboard Bernstein copula estimators in terms of pointwise error, integrated error, computation time, selected degrees, numerical stability, and pointwise coverage. A sensitivity analysis shows that (Formula presented.) is a simple theoretically admissible default that avoids the most severe oversmoothing. A descriptive application to the Loss–ALAE insurance claims data illustrates how the lower-tail Spearman's rho curve can reveal local dependence features that are not captured by the global Spearman correlation.

Aydin, Sevinç
This study was designed to observe the effects of sodium tetraborate on preventing lead metal toxicity damage to fatty acids in rat heart tissue. After the heart tissues were homogenized with Tris-HCl buffer, the separated pellet part was prepared for fatty acid analysis. The fatty acids in the obtained lipid extract were converted to methyl ester form and analyzed with SHIMADZU GC 2010 PLUS gas chromatography. When comparing the lead group with the lead + sodium tetraborate group, partial increases were observed in saturated fatty acid levels such as myristic acid (14:0), pentadecanoic acid (15:0), and palmitic acid (16:0), while varying increases were seen in some monounsaturated fatty acid levels such as palmitoleic acid (16:1, n-7), and oleic acid (18:1, n-9). Moreover, demonstrated varying levels of increases in all polyunsaturated fatty acids excluding the arachidonic acid (20:4, n-6) and adrenic acid (22:4, n-6) fatty acids. As the most notable fatty acid change in our study, arachidonic acid (20:4, n-6) fatty acid increasing in the lead group while decreasing in the sodium tetraborate group demonstrates that sodium tetraborate decreased the negative effects of oxidative stress on fatty acids. The results of this study provide supporting evidence for the potential use of sodium tetraborate in drug design to prevent the toxic effects of lead.

This study developed an exploratory heuristic decision-support framework for dynamically regulating instructor visibility in instructional videos based on learners’ eye-tracking data. Eye-movement data were collected from 40 university students using a Tobii Pro Fusion while viewing 16 explanatory and procedural instructional videos. Instructor and Learning Content Areas of Interest were analyzed using normalized eye-tracking indicators. Descriptive analyses were complemented by Wilcoxon signed-rank tests, binary logistic regression, and receiver operating characteristic (ROC) analyses. Learners allocated significantly greater visual attention to learning content than to the instructor across both video types. Logistic regression identified instructor attention percentage, visit-related metrics, and blink frequency as significant predictors of visibility decisions. ROC analysis showed that instructor attention percentage provided the highest discriminative performance, with an optimal threshold of approximately 30%. Findings suggest that instructor visibility may be particularly appropriate during introductory, summary, and conceptually demanding segments, providing empirically grounded, attention-aware guidance for adaptive instructional video interfaces.

Okyar, Ferit; Kemer, Duygu
Background Children with Down syndrome (DS) often have feeding problems, which may negatively affect the quality of life (QoL) of their parents. This study aimed to identify feeding problems in children with DS and to examine the relationship between these feeding problems and parental QoL. Methods This cross-sectional study included 105 parents of children aged 10–18 years with DS in Turkey. Data were collected through face-to-face interviews using the Screening Tool of Feeding Problems (STEP) and the SF-36 Health Survey (SF-36). Results This study indicated that the mean STEP scale scores were below the average level across all frequency × severity subscales. Parents' mean scores on the SF-36 QoL scale were above the reference mean (x̄ = 50.00) for the physical functioning, vitality, mental health, social functioning, pain, and general health perception subscales, whereas scores for the physical role limitation and emotional role limitation subscales were below the reference mean. In this study, a moderate negative correlation was found between STEP subscale scores and parents' mean SF-36 subscale scores ( p ≤ 0.05). Conclusions In this study, a significant negative correlation was found between the STEP subscale scores and the parents' mean SF-36 subscale scores. Implications to practice: Routine feeding assessments using the STEP scale should be conducted for children with DS, and nurse-led parent education programs addressing feeding problems should be implemented.

Özdemir, Osman; Yücel, Halit Lutfi; Kahraman, Gökhan
This study experimentally investigates the use of several passive cooling techniques to enhance the electrical performance of photovoltaic (PV) modules under high ambient summer temperatures in Elazığ, Turkey. Throughout the trial period of July, August, and September, a system comprising four photovoltaic panels, one designated as a reference, was developed. The first passive cooling arrangement utilized a paraffin-based phase change material (PCM) RT42HC. In the second configuration, a nano-enhanced PCM (NePCM) composite was employed, prepared by dispersing 1 mass% of Al2O3 nanoparticles into the paraffin matrix and stabilizing them with 3 mass% of sodium dodecyl sulfate (SDS) to ensure homogeneous distribution. The third, hybrid configuration integrated 14 graphene-coated parabolic pin-tipped fins mounted externally onto the aluminum enclosure housing the NePCM composite. Experimental results demonstrated that the implemented passive cooling techniques markedly decreased the panel surface temperature, thereby enhancing electrical power output and photovoltaic efficiency. The hybrid graphene-coated fin-NePCM system demonstrated superior performance, achieving a maximum surface temperature reduction of 12.65 °C, a sustained electrical efficiency increase of 6–13%, and an average daily electrical energy gain of 26.23 Wh day−1 compared to the reference module. These findings demonstrate that the integrated hybrid design is an effective and reliable passive cooling method for sustaining photovoltaic system performance under hot climate conditions.

Gülmez, Nihan; Kanellopoulos, Antonios
The demand for sustainable construction materials promotes the use of industrial waste in cement-based systems. This study examines mortars incorporating fly ash (FA) (0%, 7.5%, and 15%), waste glass, and chromite aggregates for mechanical and durability performance. Specimens underwent compressive strength, freeze–thaw, high-temperature, sulfate attack, and ultrasonic pulse velocity tests, while microstructure was characterized by x-ray diffraction, thermogravimetric analysis, and scanning electron microscopy–energy-dispersive spectroscopy. Mortars with 7.5% FA exhibited relatively high compressive strength and improved freeze–thaw resistance. The combined use of chromite and FA improved strength retention at 800°C, reaching 23 MPa with 7.5% FA and 50% chromite. The greatest sulfate resistance occurred in mortars containing 15% FA and 15% waste glass, maintaining compressive strengths of 61 and 70.9 MPa after MgSO4 and Na2SO4 exposure, respectively.

Minaz, Mert; Félix, Luís M.; Er, Akif; Köse, Özay; Ak, Kübra; Alparslan, Cem; Serdar, Osman; Aydın, Baki; Kurtul, Irmak; Hoseini, Seyyed Morteza
Anesthesia practices in aquaculture are important for preventing potential stress in fish. For this purpose, interest in natural anesthetic agents as substitute for currently used synthetic anesthetics has increased. In this context, the present study demonstrated the anesthetic efficacy of citronella oil (Cymbopogon nardus) in rainbow trout (Oncorhynchus mykiss) individuals. Based on an artificial neural network (ANN) model derived from preliminary studies, the optimal anesthetic concentration for rainbow trout individuals was estimated as 90 μL L−1. Validation of the concentration predicted by ANN revealed no time-dependent hematological or histological effects on fish to citronella oil. Furthermore, biochemical tests revealed that the partial post-anesthesia increase in ALT and AST values was transient and negligible in light of histological findings. Although oxidative stress was observed during the acute period, the enzymatic activity of SOD and CAT effectively reduced the oxidative damage, demonstrating their role in protecting the fish from oxidative stress. The antioxidant activity observed was temporary, returning to baseline levels without any accompanying tissue damage at the tested concentration. Behavioral monitoring further indicated a swift reduction in motor activity followed by a smooth recovery process, with no evident signs of stress or avoidance behaviour. Overall, these results position citronella oil as a promising natural anesthetic for rainbow trout under the studied parameters. That said, further studies involving various solvents, temperature ranges, and fish species are necessary to comprehensively establish its efficacy and safety.

Karasu, Yakup; Dogan, Adnan; Aykut, Semih; Ozturk, Burhan; Aglar, Erdal
Grapevine (Vitis vinifera L.) is an important fruit crop with considerable morphological and biochemical diversity, and autochthonous genotypes represent valuable genetic resources for breeding and conservation programs. Many local varieties remain underexplored in terms of pomological and antioxidant traits. Eighteen indigenous grape genotypes collected from Muş province (Eastern Anatolia, Türkiye) were evaluated using morphological and biochemical parameters, including berry traits, phenolic composition, vitamin C, and antioxidant activity. Multivariate analyses including PCA, HCA, and Pearson correlation were performed to classify genotypes and determine trait relationships. The first two PCA components explained 51.9% of the total variation. Antioxidant-related traits mainly contributed to PC1, whereas berry size and anthocyanin content influenced PC2. HCA grouped the genotypes into distinct clusters according to antioxidant capacity and pomological characteristics. Correlation analysis showed significant positive relationships among antioxidant-related parameters. Berry size traits were positively correlated with each other, but negatively associated with seed number and skin thickness. The combined use of pomological, biochemical, and multivariate analyses proved useful for genotype classification. The identification of antioxidant-rich genotypes may support future breeding and conservation studies. The results highlight the importance of indigenous grape germplasm for sustainable viticulture.

Karaaslan Ayhan, Nagihan; Seker, Seda
In this study, magnetic iron oxide@neodymium/alginate (Fe3O4@Nd/Alg) beads were prepared by ionic crosslinking with neodymium (Nd) ions, then subjected to heat treatment, and for the first time, effective removal of Reactive Blue 4 (RB 4) dye from aqueous solution was achieved with these beads. For this purpose, ideal adsorption conditions that significantly affect the removal of this dye were determined. The ideal adsorption conditions were determined as pH:5, contact time (t):60 min, amount of magnetic Fe3O4@Nd/Alg bead (m):10 mg, initial RB 4 dye concentration (C0):25 mg/L, temperature (T): 25 °C. Adsorption isotherm, kinetic and thermodynamic studies were carried out under the ideal adsorption conditions. The adsorption data was found to completely follow Langmuir model for RB 4 dye and the maximum adsorption capacity of RB 4 was found to be 263.16 mg/g. The adsorption kinetic data was found to be compatible with pseudo-second order and adsorption processes were explained by intraparticle diffusion. In adsorption thermodynamics studies, it has been determined that the nature of the adsorption reaction is spontaneous, endothermic and with increasing randomness. Furthermore, reuse studies of magnetic Fe3O4@Nd/Alg beads were carried out and it was determined that these beads could be used successfully up to 10 adsorption/desorption cycles.

Members of the Ajuga genus are of significant interest due to their traditional applications in various countries, and have therefore been the subject of phytochemical research investigating their natural bioactive compounds. The aim of this study was to determine the chemical composition and biological activities of various Ajuga vestita extracts (ethyl acetate, ethanol, ethanol/water and water). The biological effects assessed included antioxidant, enzyme inhibition and cytotoxic activities. The extracts were chemically profiled using ultra-high-performance liquid chromatography – electrospray ionization – quadrupole time-of-flight mass spectrometry (UHPLC-ESI-QTOF-MS), which identified 121 compounds, including iridoids, flavonoids, and phenolic acids. The ethanol/water extract exhibited superior radical scavenging activity (2,2-Diphenyl-1-picrylhydrazyl (DPPH): 43.13 mg Trolox equivalent (TE)/g; 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS): 45.37 mg TE/g) and reducing power (cupric reducing antioxidant capacity (CUPRAC): 103.43 mg TE/g; ferric reducing antioxidant power (FRAP): 45.29 mg TE/g). Regarding enzyme inhibition, the ethanol extract exhibited the greatest inhibition of acetylcholinesterase (AChE), butyrylcholinesterase (BChE), glucosidase, and tyrosinase, whereas the ethyl acetate extract was most effective against amylase. Regarding cytotoxicity, the ethyl acetate extract exhibited the strongest effect, significantly reducing cell viability in all cell lines and having a particularly strong impact on murine bone marrow stromal (S17) cells, with viability at 30.8 ± 2.7% at a concentration of 100 µg/mL. By contrast, the aqueous extract exhibited low cytotoxicity, maintaining high cell viability (over 94% at 50 µg/mL and over 74% at 100 µg/mL). Additionally, network pharmacology, molecular docking and molecular dynamics simulations were employed to investigate the multi-target mechanisms and binding stability of A. vestita phytochemicals. These findings provide new, detailed insights into A. vestita and suggest its potential as a raw material for developing health-promoting nutraceutical and pharmaceutical products.

Topcuoğlu, Ceyhun; Ozel, Alp; Tutun Yumin, Eylem; Sertel, Meral; Tug, Tuncer
BACKGROUND: Chronic obstructive pulmonary disease (COPD) is associated with respiratory muscle dysfunction, postural alterations and balance impairment. However, the impact of respiratory muscle weakness on postural control and its relationship with spinal curvature and mobility remain insufficiently clarified. OBJECTIVES: The objectives of this study were to compare postural control in individuals with COPD with and without respiratory muscle weakness; to examine the relationship among spinal curvature, spinal mobility, postural control and respiratory muscle strength; and to determine the effect of respiratory muscle strength on postural control. METHODS: This cross-sectional study included 41 clinically stable individuals with COPD aged 40–75 years. Respiratory muscle strength was assessed using a mouth pressure measurement device. Postural control and balance were evaluated with the Biodex Balance System and functional tests. Higher stability index values indicate greater postural sway and poorer balance performance, whereas lower values reflect better postural stability. Spinal curvature and mobility were assessed using the Spinal Mouse®. RESULTS: Individuals with respiratory muscle weakness showed significantly higher overall, anterior–posterior and medial–lateral stability indices, as well as worse eyes-open and eyes-closed firm-surface indices compared to those without weakness (p < 0.05). In participants with severe and very severe COPD, thoracic kyphosis angle was significantly associated with MIP, MIP% and multiple balance indices under different surface and visual conditions (p < 0.05). CONCLUSIONS: Respiratory muscle weakness is associated with impaired postural control and balance performance in individuals with COPD, and thoracic spinal curvature appears to be linked to both respiratory muscle strength and balance outcomes.

Ataş, Kübra; Mutlu, Ebru Kaya
Background: Despite the widespread use of exercise in managing tension-type headache, there remains a lack of research on the effectiveness of combined structured exercise programs. The aim of this study was to investigate the effects of a structured exercise program versus aerobic exercise of equal duration on tension-type headache (TTH). Methods: Fifty-four female participants aged between 18 and 55 years were randomised to receive a 12-week exercise program, conducted twice a week for 45 min per session. The Structured Exercise Group (SEG) participated in a combination of aerobic, strengthening, and stretching exercises, whereas the Aerobic Exercise Group (AEG) performed only aerobic exercises. The primary outcome measure was the Headache Impact Test (HIT-6), a quality-of-life questionnaire. Secondary outcome measures included headache intensity, disability level, pressure pain threshold, proprioception, muscle strength, cervical posture, exercise capacity, anxiety, and depression. Results: Both groups showed statistically significant improvements in quality of life, pain intensity, disability, anxiety, depression, exercise capacity, pressure pain threshold, and proprioception (p < 0.05). Between-group comparisons revealed that the SEG demonstrated significantly greater improvements in quality of life, pressure pain threshold, proprioception, muscle strength, and posture (p < 0.05), whereas the AEG showed superior gains in exercise capacity (p < 0.05). Conclusion: Both exercise programs appear similarly effective for self-reported outcomes. Based on clinical measurement results, we recommend incorporating strengthening and stretching exercises into the aerobic exercise program and extending the duration to 12 weeks for additional benefits. Significance Statement: This study highlights the clinical value of supervised, physiotherapist-led exercise and the integration of personalised, multi-component strategies in managing tension-type headache. While both structured and aerobic programs improved pain, activity, and participation, the structured approach provided additional benefits in pressure pain threshold, proprioception, muscle strength, and posture. Tailoring interventions to individual clinical needs and extending the duration beyond 8 weeks may further enhance outcomes.

Agdas, Mehmet Tevfik; Arik, Kaan
Road surface detection is critical for improving traffic safety and reducing road maintenance costs. Because traditional methods are time-consuming and costly, deep learning-based image processing techniques offer an important alternative in this field. This study aims to develop a model that automates the detection and segmentation of road surface defects such as potholes, manhole covers, and culverts using deep-learning-based image processing techniques. In this study, a dataset previously used in the literature was preferred. It was observed that object detection was performed using a dataset from the literature. In this study, both object detection and object segmentation were performed using different parameters. To prove the success of object segmentation, both object detection and segmentation were performed using the YOLOv8 algorithm, which has previously obtained successful results. AdamW optimization and Auto Batch parameters were selected for this study. With these parameters, object detection was first performed with the YOLOv8s model, which is one of the variances of the YOLOv8 algorithm with the most successful results in the literature, and a successful 92.8% mAP@50 performance value was obtained according to the sources in the literature. In this study, the YOLOv8n, YOLOv8s, YOLOv8m, and YOLOv8l variance models of the YOLOv8 algorithm were used with the preferred parameters, and segmentation was performed. In object segmentation, a map@50 performance value of 90.9% in all classes and 99.1% in culverts was obtained using the YOLOv8l model. A map@50 performance value of 89.1% for pothole segmentation and 88% for manhole cover segmentation was obtained using the YOLOv8s model. The results of the analyses showed consistency in precision and recall values. These findings contribute significantly to improving road safety, reducing maintenance costs, and supporting sustainable urban infrastructure. Future research could explore integrating multiple data sources and adapt these models to more complex road conditions.

This research aimed to examine the anti-genotoxic properties of Stachys viscosa, a plant of the Lamiaceae family, which has medicinal and aromatic properties and is widely used in cosmetics, food, and pharmaceutical industries. The Drosophila wing somatic mutation and recombination test (SMART), an in vivo tool for evaluating somatic mutation and recombination, was employed. The antigenotoxic effect of the S. viscosa plant against mitomycin C (MMC) mutagen was investigated. The study evaluated doses of 5 mg, 15 mg, 45 mg, and 60 mg of S. viscosa, concluding that doses of 45 mg and 60 mg effectively mitigated DNA damage induced by MMC. At doses of 45 mg and 65 mg, the total number of spots caused by MMC was suppressed by 8.21% and 13.17%, respectively. The data collected indicate that the S. viscosa plant possesses certain anti-genotoxic properties.

İncele - MakaleYalnız künye2025Scopus SJRQ1Trade openness, inequality, and internal conflict: global evidence from a dynamic panel analysis
Ates, Erdem
PurposeThis study investigates how trade openness influences internal conflict, emphasizing the moderating role of income inequality. It aims to clarify whether the benefits of globalization translate into domestic peace or exacerbate internal unrest when income distribution is unequal.Design/methodology/approachUsing an unbalanced panel of 126 countries from 1999 to 2022, the study applies a dynamic panel data framework based on two-step System Generalized Method of Moments (GMM) estimators. This approach accounts for potential endogeneity, autocorrelation, and heterogeneity across countries. Robustness tests include alternative lag structures and difference GMM estimations.FindingsEmpirical results reveal that trade openness and GDP per capita significantly reduce the risk of internal conflict, supporting the liberal peace hypothesis. In contrast, higher income inequality, inflation, democracy index, market concentration, and external conflict increase conflict risk. The findings confirm the embedded liberalism thesis, indicating that trade promotes peace only when accompanied by redistributive domestic policies that mitigate inequality.Research limitations/implicationsThis study is subject to several limitations. While it offers robust empirical findings, the use of panel data limits the ability to capture country-specific dynamics and institutional nuances. Moreover, internal conflict is a multifaceted phenomenon influenced by non-economic factors not fully addressed in the model. Despite these limitations, the results provide valuable insights for policymakers, suggesting that trade openness alone may not ensure peace without addressing domestic inequality. Future research may benefit from disaggregated analyses or mixed-method approaches to better understand the country-level mechanisms linking globalization and internal conflict.Practical implicationsThe results suggest that policymakers should complement liberalization policies with inclusive welfare measures and skill-based interventions to ensure that trade benefits are broadly shared, preventing distributional grievances that may lead to instability.Social implicationsThis study highlights the social risks of uneven globalization. While trade can promote economic growth, its benefits must be distributed fairly to prevent societal fragmentation. High income inequality can erode trust, deepen social divisions, and increase the likelihood of unrest. Furthermore, democratization without strong institutions may fail to foster cohesion, especially in developing societies. These findings stress the importance of inclusive development policies that promote both economic opportunity and social equity to ensure long-term internal stability and reduce the risk of conflict.Originality/valueThis study contributes to the literature by integrating trade theory and conflict analysis within a dynamic panel framework, offering one of the few cross-country empirical examinations of how trade openness, inequality, and internal conflict interact over time.

Gueltekin, Ahmet Kerim
The Alevi movement, originating more than three decades ago in Turkey and the Western European diaspora, has led to significant social and cultural shifts within Alevi communities. This movement witnessed the emergence of Alevi associations, increased religio-political activities, and a fervent search for a redefined Alevi identity. The quest for a comprehensive understanding of Alevi identity remains a contested debate, prominently reflected within Alevi youth, who navigate complex socio-cultural landscapes and encounter challenges in defining their identity amidst competing narratives and associations. This paper examines the identity formation strategies of young Alevis in Berlin, drawing on ethnographic fieldwork conducted between 2021 and 2023. Contrary to mainstream portrayals of Alevi youth experiencing a loss of identity, this study argues for the presence of continuity dynamics, emphasising inherited Alevi mindsets and emotions. Through interviews and analysis of a documentary produced by Berlin Alevi youth, the paper explores new narratives about Alevi history, sociology, and theology constructed by young Alevis, highlighting their role in shaping contemporary Alevism in Germany. This research contributes original data and discussions to the existing literature on Alevi youth, shedding light on their evolving identities and the dynamics of Alevi discourse in diasporic settings.

Baran, Zeki; Polat, Alper
This study investigates the electromagnetic field (EMF) permeability characteristics of widely used construction materials to determine their effectiveness in electromagnetic insulation against radiation emitted by base stations. Field measurements were conducted at 81 base stations located in the city center of Diyarbak & imath;r in accordance with the standards of the Information and Communication metal, lead, PVC, XPS, and recycled concrete. The results indicate that the highest average electromagnetic field intensity was measured in free-space conditions (3.37 V/m), whereas lead exhibited the most effective shielding performance with an average value of 1.01 V/m, corresponding to an attenuation of approximately 70%. Metal sheets also showed strong shielding capability with an average value of 1.29 V/m. Among conventional materials, recycled concrete demonstrated lower electromagnetic permeability (2.13 V/m) compared to standard concrete (2.60 V/m). Thickness-dependent measurements revealed that increasing recycled concrete thickness from 3 cm to 7 cm reduced electromagnetic field intensity from up to 2.93 V/m to as low as 1.64 V/m, representing a reduction of approximately 44%. Measurements conducted inside and outside the safety distance further confirmed that EMF levels outside the safety distance can be more than twice those measured inside. Overall, the findings demonstrate that material type, thickness, and safety distance play a critical role in reducing electromagnetic exposure. Recycled concrete emerges as a sustainable and effective alternative for electromagnetic shielding in building design.
- MakaleAçık Erişim2025Does Nepotism Trigger Quiet Quitting? A Research on Local Governments
Uyan, Umut; Ibin, Adil
The concept of quiet quitting, which denotes a cognitive and/or emotional, if not physical, detachment, has recently become one of the most frequently studied topics in organizational psychology. The term refers to performing only the tasks stipulated in job description with minimum organizational commitment and not going beyond that. Due to the detrimental effect of quiet quitting on both individual and organizational performance, it is crucial to study the phenomenon in depth. By referring to the organizational justice perspective, the study is designed to determine whether one of the negative employee experiences, nepotism, in local governments trigger quiet quitting. The main assumption of the research is that nepotism deteriorates the sense of justice, which leads employees to quit quietly. Structured questionnaires were administered to 259 local government workers in Adana. The results suggest that exposure to nepotism triggers quiet quitting in local governments where preferential treatments are allegedly pervasive. The study is expected to guide managers in establishing effective human resources practices in such institutions.

This study evaluates the effects of using bio-oil obtained from waste biomass on the physical properties, rheology, fatigue, and rutting of recycled asphalt binder. In addition, the aim of this study is to provide benefits to the environment and the economy by reusing waste materials. The bio-oils produced were produced by the pyrolysis method. B70/100 pure bitumen was chosen as the reference binder for the rejuvenation of the selected RAP binder. To ensure its properties, five different rejuvenators (two commercial + three bio-based rejuvenators) were added to the aged bitumen obtained from recycled asphalt pavement (RAP) at different rates. The produced bio-oils were compared with commercial products. The first goal of the study is to produce rejuvenators from waste materials, and the second is to achieve similar or better results with commercial rejuvenators by producing rejuvenators from waste materials. When the test results are examined, it can be seen that the aged binder was rejuvenated to the desired hardness by adding rejuvenator to it. It is seen that the penetration value of the aged binder increased by the addition of rejuvenator, whereas the softening point and viscosity values decreased.
