Kenek, Gökhan; Sımsek, Tugçe
This study aims to examine the impact of workaholism on work-family conflict and whether employees’ gender moderates this relationship. The research was conducted with 401 academicians from all public universities (8 in total) in Ankara, selected through a snowball sampling method. Data were analyzed using MPLUS 7 and SPSS 26 statistical software. The findings revealed that workaholism has a significant positive effect on work-family conflict; however, gender did not moderate the relationship between the two variables. Additionally, the results indicated that attitudes toward both workaholism and work-family conflict differ significantly by gender, with women academics reporting higher levels than their male counterparts. These findings suggest that although female academics report higher levels of both workaholism and work-family conflict, gender does not alter the strength of the association between the two, indicating that workaholism contributes to work-family conflict in a similar way across genders.

Tuncer, Metin; Tuncer, Gülsüm Zekiye; Yigit, Tülay Tuğçe
Objective: The aim of this study is to adapt the Friedman Life Balance Scale (FLBS), originally developed in the USA, into Turkish and to examine its validity and reliability for assessing life balance among nursing students. Material and Methods: This methodological study was conducted with a sample of 688 nursing students enrolled in the faculty of nursing between November 2023-February 2024. The data were collected using the Satisfaction with Life Scale (SLS), the Warwick-Edinburgh Mental Well-Being Scale Short Form (WEMWBSF), and the FLBS. Initially developed in English, the 15-item scale comprising 3 sub-dimensions underwent Turkish language and content validity procedures. Results: The factor analysis results of the FLBS indicated that the construct validity was satisfactory. Exploratory factor analysis revealed a 3-factor structure accounting for 55.9% of the total variance. The goodness of fit values (χ2 /df=3.516; Comparative Fit Index=0.953; Normed Fit Index=0.936; Incremental Fit Index=0.954; Tucker-Lewis Index (TLI)=0.931; Root Mean Square Error of Approximation=0.060) of the model obtained with this 3-factor confirmatory factor analysis were good. The internal consistency Cronbach’s alpha score of the FLBS was 0.861. In parallel form reliability of the FLBS, there was a low-level positive relationship between the FLBS and SLS (r=0.348, p<0.001) and a moderate positive relationship between the FLBS and WEMWBS (r=0.594, p<0.001). Conclusion: In this study, the Turkish version of the FLBS is a reliable and valid measurement tool for measuring life balance in nursing students. FLBS is a short and practical scale to measure life balance. It is thought that the FLBS can be used to measure life balance in students and health professionals.

Akyol, Mehmet; Soyyigit, Semanur
This study assessed the environmental technological innovation (ETI) of the 13 countries with the highest industrial added value (China, the United States, Japan, Germany, India, the United Kingdom, South Korea, France, Russia, Italy, Mexico, Brazil, Indonesia) over the period between 1992 and 2019. The objective is to evaluate the impact of carbon dioxide (CO2) emissions, trade openness (TO), and economic growth (EG) on the ecological footprint (EFP). In this study, a panel data analysis was conducted utilizing the second-generation PANIC unit root test, the Westerlund cointegration test, the Dumitrescu-Hurlin causality test, and the common correlated effect mean group (CCEMG) and augmented mean group (AMG) estimator methods. The results of the analysis demonstrate that, according to the CCEMG, ETI exerts a mitigating influence on EFP in Indonesia. In numerous countries, CO2 has been observed to increase EFP, whereas in a select few countries, EG has been found to have a similar effect. Conversely, in China and South Korea, TO has been identified as a factor contributing to an increase in EFP, while in the United States, it has been identified as a factor that contributes to a decrease in EFP. The AMG indicates that ETI results in a decrease in EFP in Brazil and Indonesia, while simultaneously producing an increase in Mexico. While CO2 is observed to increase EFP in numerous countries, EG is seen to increase EFP in many countries, although this is only the case in India. TO is found to decrease EFP in China, India, South Korea, and Brazil, while simultaneously increasing it in Germany. The empirical evidence suggests that policies aimed at limiting uncontrolled economic growth, prioritising environmentally friendly technological innovations, improving international trade processes and policies with the objective of reducing emissions, and developing environmentally friendly processes and products in production are likely to be effective.

İncele - MakaleAçık Erişim2025Investigation of parents with high-risk infant on participation in care, depression, quality of life, and anxiety according to the infant's severity of neurologic impact
Sen, Muserref Ebru; Yakut, Hatice
Aim: The study aims to examine the psychological consequences such as anxiety levels, quality of life, depression, and participation in the care of parents with high-risk infants who have varying levels of neurological impact severity. Material and Methods: Forty high-risk infants and their mothers were included in the study. The infants were divided into three groups according to the Dubowitz Neurologic Assessment Scale. The State-Trait Anxiety Inventory (STAI), Edinburgh Postpartum Depression Scale (EPDS), Quality of Life Short Form 36 (SF-36), and the NICU Care Participation Scale were administered. Results: There were significant differences in the mothers' anxiety and depression levels (p < 0.001) and many parameters of quality of life according to the severity of neurological impact. However, it was determined that the severity of the neurological impact did not affect the mothers' participation in care (p > 0.01). Discussion: Although our study revealed that parents' depression, anxiety, and quality of life levels changed according to the severity of neurological impairment in high-risk infants, care participation was not affected. The limited sample size and the inability to generalize the results to different cultural and socioeconomic groups are important limitations. Nevertheless, it can be concluded that the medical condition of the newborn seriously affects the mental health of the parents.
- MakaleAçık Erişim2025The effect of SARS-CoV-2 pandemic on anxiety levels and attitudes towards e-learning among sports sciences students
Türker, Ustun; Bostanci, Ozgur
Background and Study Aim The COVID-19 pandemic has led to significant changes in education and teaching processes, particularly affecting application-based disciplines such as sports science. This study aimed to examine the relationship between COVID-19-related anxiety and attitudes toward e-learning among sports sciences students. Material and Methods The study was conducted using a cross-sectional design with 2,479 students from 14 state universities in Turkey. Data were collected using the Coronavirus Anxiety Scale (CAS) and the Test of E-Learning Related Attitudes Scale (TELRA), and responses were gathered through online surveys. Parametric statistical analyses (t-test, correlation) were performed using SPSS at a significance level of p<0.05. Results Anxiety associated with the SARS-CoV-2 pandemic led to significant changes in the e-learning attitudes of sports sciences students. Students with higher levels of anxiety exhibited stronger tendencies toward technology use and perceived usefulness, whereas only limited differences were noted in satisfaction and motivation. Female students reported higher levels of symptoms and anxiety, while those who engaged in regular exercise demonstrated lower anxiety levels. Interestingly, within the high-anxiety group, students who did not regularly participate in exercise displayed more favorable e-learning attitudes. These findings suggest that anxiety may strengthen the inclination toward digital learning; however, this tendency does not always align with motivational commitment. Conclusions The e-learning attitudes of sports sciences students during the pandemic were influenced by factors such as technological competence, psychological state, gender, exercise habits, and the requirements of practical courses. The findings highlight the importance of designing hybrid and flexible learning models in times of crisis, in a manner that integrates psychological support with pedagogical needs.

Cona, Lale
Fractional calculus, which involves derivatives and integrals of non-integer order, is widely used in modeling real-world problems in science and engineering. This study focuses on solving fractional integro-differential equations using Picard's three-step iteration algorithm. We apply Picard's three-step iteration algorithm to approximate solutions and show that it converges strongly. The method is shown to be not only efficient in approximating solutions but also robust with respect to perturbations in the initial data and operators, demonstrating its data dependence. A numerical example is provided to illustrate the theoretical results and to confirm the applicability and reliability of the proposed approach.

Aksüt, Yavuz Selim; Çullu, Mustafa; Yetgin, Sukru
The indirect assessment of concrete compressive strength using non-destructive techniques, including the Schmidt rebound hammer and ultrasonic pulse velocity methods, is crucial for evaluating and tracking the strength of structural concrete used in construction and rehabilitation projects. However, studies focusing on alkali-activated concrete (AAC) remain insufficient. This study investigates the mechanical properties of fiber-reinforced alkali-activated concretes (FAACs) produced with short curing times, addressing this gap in the literature. Ground blast furnace slag (GBFS) was used as the binder, and waste volcanic rock dust (RD), produced in a natural stone processing plant, served as a fine filler. These materials were activated with sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) to produce alkali-activated concrete, both without fibers (AAC) and with fibers (FAAC). Steel fiber (SF) and polyester fiber (PYF) were used separately and in hybrid forms at 0.25%; 0.50%; 0.75%, and 1.0% volume fractions, resulting in a total of 117 cubic specimens (15x15x15 cm). The specimens' mechanical properties were evaluated using regression analyses based on data from Schmidt rebound number (RN), ultrasonic pulse velocity (UPV) non-destructive methods and uniaxial compressive strength (UCS) destructive tests. Optimized functions predicting compressive strength based on RN and UPV measurements were developed, highlighting the significant effects of fiber type, ratio, and mode of use. Additionally, multivariate prediction models were statistically developed using data from the three test methods.

Cicerali, Derya; Yücel, Cem; Aydinçakir, Emre; Kaygusuz, Abdullah
This study aimed to constrain the crystallization and emplacement conditions of magmas that produced the Late Miocene volcanic rocks exposed at the junction of the Erzurum-Kars Plateau and the Eastern Pontides in the Northeastern Anatolia Region through a series of thermobarometric analyses. The volcanic succession unconformably overlies Oligocene mudstone, siltstone, and sandstone alternations, with limestone and cherty limestone at higher levels. Petrographically, they consist offine-to coarse-grained basalt, basaltic andesite, and andesite. Mineral compositions include plagioclase (An(16-77)), clinopyroxene (Wo(39-45)En(43-50)Fs(11-12)), orthopyroxene (Wo(3-4)En(73-82)Fs(14-24)), olivine (Fo(63-86)), hornblende (Mg#=0.62-0.79), and Fe-Ti oxides (Usp(0.05-1.44), Ilm(94.10-95.53)). The groundmass comprises microlites of these minerals and volcanic glass. The dominant textures are microlitic porphyritic, hyalomicrolitic, and microlitic porphyritic, while glomeroporphyritic, intergranular, pilotaxitic, subophitic, flow, and vesicular textures are also observed. Widely present disequilibrium features, such as zoning, sieve, and resorption, are common in plagioclase and clinopyroxene. Thermobarometric calculations indicate crystallization temperatures of 880-1230 degrees C, pressures of 0.73-8.71 kbar, oxygen fugacities between (-10.94) and (-8.92), and water contents of4.60-6.32 wt.%. These results suggest that the volcanic rocks crystallized under volatile-rich, oxidizing conditions across a broad depth range (similar to 2-32 km), at relatively high temperatures.

Özkan, Vildane; Dinç, Artum
In the post-globalization era, global elites face a transformed landscape of resurgent national sovereignty and civilizational rhetoric. This article examines how transnational power-holders-once emblematic of a borderless world - are recalibrating their cultural strategies and legitimacy mechanisms amid these shifts. Drawing on cultural sociology and elite theory (Bourdieu, Bauman, Castells, Gramsci), the analysis integrates non-Western scholarly perspectives. It reconceptualizes cosmopolitan elite culture under conditions of de-globalization. We argue that global elites are neither passive victims of de-globalization nor static cosmopolitans. Instead, they act as cultural brokers who selectively adjust their identities and narratives. Some accentuate patriotic or civilizational themes to align with ascendant statecentric discourses, while others redouble on universalist rhetoric through new transnational alliances. Comparative illustrations from Western countries, Russia, China, and T & uuml;rkiye demonstrate that elites are actively adapting to a fragmented world order. These shifts suggest that sociological inquiry needs to move beyond treating globalization as a given context and toward analyzing the cultural dynamics of elite power in a fractured world-one where questions of meaning, identity, and legitimacy have become as pivotal as economic forces.

Spontaneous retroperitoneal hemorrhage (SRH) is a rare and potentially life-threatening condition, often challenging to diagnose and manage, especially in elderly patients with multiple comorbidities. Psoas hematoma is a known complication that can be associated with anticoagulation therapy. A 93-year-old male patient with a history of atrial fibrillation, chronic heartfailure, and anticoagulant use (apixaban) presented with complaints of dizziness following a fall in the bathroom. He was initially assessed in the neurology clinic for potential cognitive symptoms; however, while awaiting assessment, he experienced a syncopal episode, resulting in his transfer to the emergency room. The patient had a significant reduction in hemoglobin levels, necessitating additional examination. Imaging revealed an 8 cm left psoas hematoma with active extravasation. The patient received a blood transfusion, vitamin K, and therapeutic interventions, including interventional radiology, which effectively halted the hemorrhage. This case highlights the diagnostic complexity and therapeutic challenges posed by spontaneous retroperitoneal hemorrhage in elderly patients, especially those on anticoagulant therapy. Early recognition and appropriate intervention are crucial for patient recovery.

Sahin Macit, Nazife
This study analytically assesses the climate change and environmental sustainability performance of G20 countries using data from the 2024 Climate Change Performance Index (CCPI) and Environmental Performance Index (EPI) reports. The analysis employs Sum-Weighted Information (SWI) and Ranking Alternatives with Weights of Criterion (RAWEC), which are Logarithmic Decomposition of Criteria Importance (LODECI)-based multi-criteria decision-making (MCDM) methods. The study created three separate decision matrices, taking into account the CCPI and EPI criteria individually, as well as their combination. The criterion weights were determined using the LODECI method; greenhouse gas emissions, climate policy, and air quality were the most significant criteria. The results show that China and Saudi Arabia demonstrate strong environmental performance in CCPI-based rankings, while Germany, the United Kingdom and France demonstrate strong performance in EPIbased evaluations. In the integrated analysis, Germany ranked first using both methods. The consistency of the rankings obtained using the SWI and RAWEC methods was high, which supports the reliability of the analyses. However, some differences in ranking were observed depending on the method used, the distribution of criteria and the country sample. Overall, the study emphasizes the pivotal role of methodological diversity and data-driven approaches in multidimensional environmental assessments for policy-making, while demonstrating the robustness of the findings through sensitivity and comparative analyses.

Cicen, Yildirim Beyazit
This study delves into the pandemic's influence on unemployment rates, employing the concept of transaction costs. Given the virus's infectious nature, each transaction carries the risk of infection. In this study, Covid-19-induced transaction costs were utilized to gauge the pandemic's impact on unemployment rates. Seven developed countries and seven developing countries were separately scrutinized for this purpose. According to the outcomes of Yilanci and Gorus' (2020) panel causality test, Covid-19-induced transaction costs did not influence unemployment rates in developed countries. However, they significantly impacted unemployment rates in developing countries. These findings underscore the resource gap between developed and developing nations in tackling pandemic-related challenges. Policymakers should consider these economic disparities when devising strategies to alleviate the pandemic's effects.

Sahin, Fatih
University-industry collaborations have gained increasing recognition as a key indicator of innovation ecosystems in recent years. However, existing literature often overlooks the expanding and diversifying roles of universities, focusing primarily on their impact on innovation. This study seeks to address this gap by exploring the effects of university-industry collaborations on outward foreign direct investment (FDI) activities in underdeveloped and developing countries, which face significant disadvantages in terms of technological and innovative resources. Additionally, it examines the regulatory role of the quality of the education system, which is believed to influence the effectiveness of these collaborations in fostering outward FDI. Using a sample of 80 underdeveloped and developing countries, panel regression analysis was conducted on secondary data covering the years 2013-2022. The findings reveal that university-industry collaborations positively influence crossborder investments, with these effects being stronger in countries with higher levels of education expenditures. These positive effects, however, disappear in contexts where education expenditures are low. This study makes important theoretical contributions to the and developing countries, highlighting the significance of university collaborations and the education system, in contrast to firm-specific resources. It also provides valuable policy recommendations for decision-makers in these countries.

Çavdar, Ozlem
Concrete structures designed prior to the implementation of modern building codes are still in use today. These structures are known for their inadequate design and poor performance during earthquakes. In this study, a performance analysis was conducted on an existing school structure in Istanbul, Turkey. The reasons for the damage were explored, and the structure was evaluated to determine the necessity for strengthening, the potential strengthening methods, and the appropriate comparison. Finally, recommendations were presented based on the available data from this study. The building was constructed in 1996 and has calculation reports and a static project. Linear and nonlinear methods were employed to determine the earthquake safety of structures after a mathematical model was created. The earthquake resistance of both the existing and retrofitting states of the school building was analyzed using linear and nonlinear analysis methods. The controlled damage limit could not be determined due to the high seismic intensity. A retrofit project has been devised for this low seismic performance building, comprising column jacketing, wrapping of beams with FRP, and the addition of shear walls.
