    Dini Milliyetçiliğin Müphemliği: Kavramsal Bir Berraklaştırma Girişimi

    No full text
    Milliyetçilik çalışmalarında uzun süre ihmal edilen milliyetçilik ile kutsal inançlar ara- sındaki ilişki, günümüzde devletlerin, devlet dışı aktörlerin ve siyasi liderlerin dinin duy- gusal repertuarına sıkça başvurmasıyla birlikte belirginlik kazanmıştır. Bununla birlikte, dini milliyetçiliğe ilişkin literatür kavramsal ve kuramsal düzeyde henüz yeterince olgun- laşmamıştır. Bu çalışma, kavramın içerdiği belirsizlikleri ele alarak, bu sorunu aşmak amacıyla üçlü bir kategori önerisinde bulunmaktadır. İlk kategoride, dinin etnik kimlikle özdeşleşmesi ve zamanla etnikleşmesi incelenirken; ikincide, dinin milli ideallerle bütün- leşerek ulusal birliğin pekişmesindeki rolüne ışık tutulmaktadır. Üçüncü kategori ise, dini kimliğin medeniyet düzeyinde sınır inşası işlevine odaklanmaktadır. Çalışma, seküler ve dini milliyetçilik arasındaki karmaşık etkileşimlerin hibrit modeller ortaya çıkardığını ve sekülerleşme ile dindarlaşma süreçlerinin esnek, bağlama duyarlı ve yeniden üretilebilir olduğunu savunmaktadır

    Energy demand and environmental problems are increasing day by day as global threats. The burning of fossil fuels has harmful effects on ecological systems. Global threats related to energy can be eliminated by environmentally friendly, cost-effective, and renewable resources. Hydrogen is among the sustainable and renewable energy sources due to being the most common element on earth, non-toxic reaction products and having high calorific value. It was the first time nickel-organo-silica supported magnetic nanocatalysts (MNCs) were synthesised in this study. These synthesized MNCs were characterized in detail. Then, these MNCs were used to produce hydrogen from sodium borohydride in high efficiency. The saturation magnetization value and average particle size of the Fe3O4@SiO2@Tris@Ni MNCs have been measured as 33.27 emu/g and 10.26 nm, respectively. The Fe3O4@SiO2@Tris@Ni MNCs were used for the first time in hydrogen generation in this study. The hydrogen generation by sodium borohydride (NaBH4) methanolysis/ethylene glycolysis of the catalyst has been carried out at 298 K using 0.75 % NaBH4, 75 mg nanocatalyst, and 20 mL methanol/ethylene glycol. The amount of hydrogen produced in the methanol/ethylene glycol processes has been measured as 2167 mL H2/g NaBH4. The highest hydrogen generation rate has been obtained using 0.75 % NaBH4, 75 mg catalyst, and 20 mL ethylene glycol, and this value was calculated as 1067 mL H2/(min & sdot;gcat). The reusability performance of the catalyst was determined to have a decrease of 25.86 % after the fifth cycle compared to the initial use. According to these results, the catalyst is a promising material with advantages such as high efficiency in hydrogen generation and the possibility of repeated use.[MAU.

    Background This study aimed to examine the adaptation processes and anxiety levels of university students living with earthquake survivor families placed in state dormitories after recent major earthquakes. Materials and Methods A descriptive, cross-sectional quantitative study was conducted in a state dormitory between May and August 2023. A total of 108 students participated using the snowball sampling method. Data were collected through a Descriptive Characteristics Form and the Beck Anxiety Scale. Statistical analyses included descriptive statistics and linear regression using SPSS 25.0. Results Among the participants, 49% reported increased frequency of contact with their families after the earthquake. Sharing the same dormitory space with earthquake-affected families led to limited personal space for 56%, emotional impact for 51%, and benefits such as emotional support for 56%. Additionally, 45% noted changes in their attitudes, 46% in their social lives, and 56% in their social responsibility awareness. Regression analysis showed that sharing the same environment with families explained 33.7% of the variance in Beck anxiety scores. A significant positive relationship was found between cohabitation with families and anxiety levels (B=0.337, p Conclusions The findings indicate that post-earthquake family cohabitation significantly affects students' psychological and social well-being. Living in close proximity to affected family members increases anxiety levels. Providing psychological support services for students is crucial to reduce anxiety and facilitate post-disaster recovery and adaptation

    Cevik, Orhan/0000-0002-1519-4376; Aslan, Yavuz/0000-0002-6692-5247;This study aims to examine the relationships between socioeconomic status (SES), life satisfaction, and perceived human rights practices (PHRP) within the framework of Bandura's social cognitive theory, which emphasizes the interaction of personal, environmental, and behavioral factors in shaping perceptions and behaviors. By integrating this perspective, the study provides a novel understanding of how socioeconomic factors and well-being influence human rights perceptions. In addition, a revalidation study of the Human Rights in the Context of Generational Rights Scale was conducted. The research was designed as a quantitative and cross-sectional study. A total of 791 adults living in different cities in T & uuml;rkiye were reached online in June 2022. The data collection tools were a demographic information form, the revalidated version of Human Rights in the Context of Generational Rights Scale, and the Life Satisfaction Scale. The collected data were analysed using IBM's SPSS v.26 and SPSS Amos v.24 and Hayes' Process Macro plug-in v.4.2. It was found that SES has a direct negative effect on PHRP and an indirect positive effect through life satisfaction. In addition, political opinion was found to have a moderating effect on the relationship between SES and PHRP in terms of government and opposition. These findings suggest that perceptions of human rights are influenced not only by structural socioeconomic conditions but also by subjective well-being and political affiliations. This highlights the importance of considering psychological and ideological factors in discussions on human rights perceptions, providing implications for policymakers and scholars examining social inequalities and governance

    No full text
    This study examines the influence of Inclusive Leadership (IL) on Thriving at Work (TW) and Career Sustainability (CS), with a particular focus on the mediating role of thriving in Humanitarian Organizations (HOs). Drawing on Self-Determination Theory (SDT), the Job Demands-Resources (JD-R) model, and Social Information Processing Theory (SIPT), the research presents IL as a contextual resource that encourages psychological safety, fairness, and openness. By fostering these conditions, IL strengthens employees' vitality and capacity for learning, enabling them to remain adaptable and maintain their careers in demanding environments. Survey data were collected from 264 employees working in both international and local humanitarian organizations, and structural equation modeling (SEM) was applied to test the proposed framework. The results indicate that IL has a positive effect on TW, and that thriving partially mediates the link between IL and CS. This demonstrates the crucial role of thriving in converting Inclusive Leadership behaviors into long-term career outcomes. Theoretically, the study advances leadership and career research by integrating IL, thriving, and sustainability into a unified framework. Practically, it suggests that humanitarian organizations should prioritize leadership development and foster supportive environments that build resilience, promote continuous learning, and enhance employee well-being

    In recent years, interest in the eco-friendly manufacturing of metal nanoparticles from plant extracts has surged. Nonetheless, no research has examined the combined antibacterial and anticancer properties of SeNPs synthesized with Solanum tuberosum (S. tuberosum) extract. This study involved the synthesis of selenium nanoparticles (ST-SeNPs) utilizing phytochemicals with reducing and capturing properties derived from the aqueous extract of S. tuberosum shell through a green synthesis approach. To determine the unique characteristics of ST-SeNPs nanoparticles, a variety of techniques were used, including scanning electron microscopy (SEM), zeta potential analysis, transmission electron microscopy (TEM), dynamic light scattering (DLS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UV-visible (UV-Vis) spectroscopy, and energy dispersive X-ray spectrometry (EDX). The optical characteristics of ST-SeNPs were validated using UV-Vis measurement, revealing the peak absorbance at 350 nm. FTIR examination verified the presence of functional groups on the surface of the produced ST-SeNPs nanoparticles. Upon examination of the SEM results, it was concluded that the synthesized SeNPs exhibited uniform distribution and possessed a round morphology. The anticancer efficacy of the produced nanoparticles on the A549 lung cancer cell line and OVCAR-3 ovarian cancer cell line after 24 and 48 hours of exposure was assessed using the MTT test. It was established that elevated concentration inhibited cell growth. The inhibitory efficacy of SeNPs against the proliferation of Escherichia coli (E. coli), Staphylococcus aureus (S. aureus), and Candida albicans (C. albicans) was assessed using the disk diffusion agar technique. The evaluated SeNPs exhibited antibacterial efficacy against bacterial and yeast cells. The results indicate that ST-SeNPs produced via green synthesis can serve as anticancer and antibacterial agents

    Elbarbary, Zakaria/0000-0003-1750-9244; Alpsalaz, Feyyaz/0000-0002-7695-6426; Aslan, Emrah/0000-0002-0181-3658Power transformers are critical components in ensuring the continuous and stable operation of power systems. Failures in these units can lead to significant power outages and costly downtime. Existing maintenance strategies often fail to accurately predict such failures, highlighting the need for novel predictive approaches. This study aims to improve the reliability of power systems by predicting transformer failures through the integration of IoT technologies and advanced machine learning techniques. The proposed hybrid model combines the LightGBM algorithm with GridSearch optimization to achieve both high predictive accuracy and computational efficiency. In addition, the model enhances interpretability by incorporating SHapley Additive exPlanations (SHAP) and Local Interpretable Model-Agnostic Explanations (LIME) for transparent decision making. The study presents a detailed comparison of different classification algorithms and evaluates their performance using metrics such as accuracy, recall, and F1 score. The results show that the hybrid model outperforms other methods, achieving an accuracy of 99.91%. The SHAP and LIME analyses provide engineers and researchers with valuable insights by highlighting the most influential features in failure prediction. In addition, the model's ability to efficiently handle large data sets enhances its practicality in real-world power systems. By proposing an innovative approach to failure prediction, this research contributes to both the theoretical foundation and practical advancement of sustainable and reliable energy infrastructures.Deanship of Research and Graduate Studies at King Khalid University [RGP2/108/46]The authors extend their appreciation to the Deanship of Research and Graduate Studies at King Khalid University for funding this work through Small Research Project under grant number RGP2/108/46

    No full text
    Objectives: The relationship between hemoglobin, albumin, lymphocyte, platelet (HALP) score, and various cancers and cardiovascular diseases has been tested previously. However, the relationship between HALP score and non-valvular atrial fibrillation (NVAF) has not been adequately tested. Therefore, our study aimed to investigate the relationship between HALP score and mortality in patients with NVAF. Methods: This study included 2,592 NVAF patients from 35 centers in Turkey. Patients were divided into two groups: those with HALP scores 58.96 (high HALP score group, 1,296 patients). The primary outcome measured was all-cause mortality. Results: The mean HALP score was 66 +/- 33. Patients in the low HALP score group had higher 1- and 5-year all-cause mortality rates (1-year: 12.9% vs. 5.4%, p < 0.001; 5-year: 38.5% vs. 20.2%, p < 0.001). Cox regression analysis identified the HALP score as an independent predictor of mortality (1-year: HR = 0.987, 95% CI = 0.981-0.992, p < 0.001; 5-year: HR = 0.990, 95% CI = 0.987-0.993, p < 0.001). ROC analysis determined a HALP score 52.3 predicted 1-year mortality with 62.9% sensitivity and 62% specificity (AUC = 0.680); a score of 55 predicted 5-year mortality with 60.3% sensitivity and 62.2% specificity (AUC = 0.657). Kaplan-Meier analysis revealed increasing mortality over time in the low HALP score group (log-rank tests, 1-year = 44.86, p < 0.001; 5-year = 108.54, p < 0.001). Conclusions: The HALP score is a simple, accessible measure, and our findings suggest that lower HALP scores are associated with increased 1-year and 5-year mortality in NVAF patients. This provides a reference for clinicians assessing risk in this vulnerable population
