The Psychometric Properties of the Turkish Version of the Stress Scale for Siblings of Childhood Cancer Patients
No full textAim: This study aimed to evaluate the psychometric characteristics of the Turkish version of the "Stress Scale for Siblings of Childhood Cancer Patients (SCCP)".
Methods: This study was conducted with 273 siblings aged 11-16 of childhood cancer patients (SCCPs) who were treated in a hospital in the Black Sea Region of Türkiye between March 2022 and April 2024. Data were collected with "The Sociodemographic Information Form" and "SCCP". The data were examined through descriptive statistics, as well as exploratory and confirmatory factor analyzes.
Results: The SCCP Turkish version is a valid and reliable scale consisting of 27 items and six sub-dimensions. The SCCP Turkish version explained 77.676% of the total variance. The SCCP Turkish version was found to be summable according to Tukey's test of additivity (p = 0.334), and the test-retest reliability of the scale was r = 0.864 (p < 0.05).
Conclusion: This study indicate that the Turkish version of the SCCP is a valid and reliable instrument for evaluating stress levels in siblings aged 11 to 16.
Practice implications: With SCCP, nurses can determine the stress levels of SCCPs and contribute to the planning of necessary interventions to cope with stress.4004030
The Effect of Boric Acid on Oxidative Stress, Inflammation, and Apoptosis in Embryonic and Fetal Tissues Damage Caused by Consumption of High-Fructose Corn Syrup in Pregnant Rats
No full textThis study aimed to determine the protective role of boric acid in a pregnant rat model of high fructose corn syrup consumption. Consumption of high fructose corn syrup has been associated with adverse health outcomes in humans and animals. Twenty-eight healthy female Wistar albino rats (250-300 g weight and 16-24 weeks old) were randomly distributed into four equal groups (n = 7): Control, Boric acid (BA), High Fructose Corn Syrup (HFCS), HFCS + BA. Boric acid (20 mg/kg) was administered to pregnant rats via oral gavage every day during pregnancy. The prepared 30% HFCS (F30) solution (24% fructose, 28% dextrose) was added to the drinking water throughout pregnancy. At the end of pregnancy (day 19), blood, placenta, uterus, and fetuses were collected from rats. The results indicated that HFCS increases oxidative stress by increasing the level of MDA and decreasing GSH, SOD, and CAT activity in the blood of maternal. However, BA administration significantly decreased MDA levels and increased GSH levels, SOD, and CAT activity (p < 0.05). In addition, HFCS consumption significantly increased plasma TNF-α, IL-6, and leptin levels compared to control, BA, and HFCS + BA groups (p < 0.05). However, BA administration significantly decreased plasma TNF-α, IL-6, and leptin levels (p < 0.05). Furthermore, BA (20 mg/kg) significantly decreased HFCS-induced histopathological and immunohistochemical alterations in the placenta, uterus, and fetal tissue. In conclusion, BA may prevent HFCS toxicity in maternal and fetal tissues, as it regulates oxidative imbalance in pregnant rat and alleviates histopathological and immunohistochemical changes. The findings indicate a need for further studies to assess the potential of boron in preventing or mitigating the effects of HFCS during pregnancy.3982179
Exploring the Correlation of Physiological Stress Signals with Student Exam Performance: A Preliminary Study
No full textStress responses in real-world settings are less studied compared to controlled laboratory environments, limiting our understanding of their impact on cognitive performance. This study investigates the relationship between physiological stress signals and academic performance using an open-access dataset of 10 students assessed across three exam sessions (Midterm 1, Midterm 2, and Final Exam). Physiological measures, including electrodermal activity (EDA), heart rate (HR), and skin surface temperature (TEMP), along with exam grades, were analyzed using traditional hypothesis testing, bootstrap method, correlation analysis, and regression tree modeling. To address the small sample size, we validated traditional hypothesis test results with the bootstrap method, and both approaches were compatible. Hypothesis testing revealed no significant differences in physiological measures across exam sessions, supporting the null hypothesis. Grades differed significantly between the final exam and both midterms (p < 0.05). Stress fluctuations were also analyzed across three periods (beginning, middle, and end) for each exam, revealing temporal response variations. Correlation analysis showed a moderate negative relationship between EDA and HR (r = - 0.504, p < 0.01) and a weak positive relationship between EDA and TEMP (r = 0.417, p < 0.05), both intensifying during the final exam. Regression analysis explained 78% of the variance in grades (R2 = 0.78), with regression tree modeling identifying lower skin temperature (< 28 °C) and higher EDA (≥ 0.19) as predictors of poorer performance. These findings underscore the interplay between physiological stress responses and academic outcomes, emphasizing the need for further research and interventions to support student success.3982150
Earthquake Performance Analysis and Retrofitting of an Existing School Building by Different Methods
No full textConcrete 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. © 2025 American Society of Civil Engineers
Assessing Internalized Beliefs: Psychometric Evidences for the Pathogenic Belief Scale in Turkish Culture
No full textThis study was conducted to test the reliability and validity of the Pathogenic Belief Scale (PBS) on adult individuals. Participants consisted of 299 adults, including 189 (63.2%) females and 110 (36.8%) males, with a mean age of 21.16 years (SD = 3.68). Personal Information Form, Pathogenic Belief Scale-R, Cognitive Distortions Scale, and Dysfunctional Attitude Scale were used as data collection tools. The three-dimensional structure of the PBS was confirmed by confirmatory factor analysis on the Turkish sample (χ2 = 204.990, df = 186, χ2/df = 1.102, comparative fit index = 0.997, normed fit index = 0.997, standardized root mean square residual = .058, and root-mean-square error of approximation = .019 (90% confidence interval [.001, .032]). Factor loadings were found to be between .470 and .761. The analyses also showed that the internal consistency reliability coefficients were at a quite good level for the undeserving dimension (α = .874, ω = 0.875), the cannot rely on others dimension (α = 0.794, ω = 0.799), and the interpersonal guilt dimension (α = .847, ω = 0.857). The Turkish version of the PBS is a valid and reliable tool that can be used to evaluate the pathogenic beliefs of individuals. The research results were discussed, and certain inferences were made for the future in line with the limitations.3978861
Agrivoltaic system design for sugar beets and wheat in central Anatolia
No full textAgrivoltaic systems, which integrate photovoltaic (PV) panels with the usage of agricultural land, emerge as a promising strategy by facilitating the simultaneous generation of renewable energy alongside the cultivation of various crops within the same area. This research is centered on the design and implementation of an agrivoltaic system that is specifically customized for the cultivation of wheat and sugar beet in the Central Anatolia Region of Turkey. The primary objective of this research is to optimize the spatial arrangement of the PV panels to achieve a balance between the generation of energy and the productivity of the crops. Through a detailed assessment of shading effects and Photosynthetic Photon Flux Density (PPFD) levels, this investigation will endeavor to unravel the complex interplay between panel configuration and its consequential impacts on both plant growth and energy output. In this investigation, the shading impacts attributed to three distinct configurations—specifically, the conventional solar power plant (SPP), the intermittently arranged panel layout, and the intermittently arranged V-shaped panel configuration—were assessed, and their appropriateness for the cultivation of wheat and sugar beet was evaluated. The V-shaped design, which additionally facilitates rainwater collection, yielded an enhanced PPFD value across the three designated regions beneath the panels. © 2025 Elsevier Lt
Hematology patients’ metaphorical perceptions of the disease and psychosocial support needs in the treatment process: a phenomenological study from a rural region of Türkiye
No full textPurpose: Although health services and access to these services have increased worldwide, there are still major barriers to access to health services, especially for rural, poor, and disabled individuals. The aim of this study was to evaluate the metaphorical perceptions of hematology patients living in rural areas in Türkiye about the disease and their psychosocial support needs during the treatment process with a phenomenological approach. Methods: In this study, in which the phenomenological research method was used, semi-structured in-depth interviews were conducted with 14 hematology patients receiving treatment in a state hospital in a province in the eastern region of Türkiye. Criterion sampling method, one of the purposive sampling methods, was used to reach the sample group. Interviews continued until data saturation was achieved. The data of the study were evaluated using thematic analysis. The study was conducted and reported according to the COREQ checklist. Results: Data analysis revealed two main themes including the following: metaphorical perceptions towards hematologic cancer with the sub-themes of emotional turmoil, social alienation and stigma and physical debilitation, and pathways to resilience with the sub-themes of disease process management, inner resilience and faith, and psychosocial support. Conclusion: This study revealed that the adaptation process of patients to hematologic cancer is quite difficult, and psychosocial support is an indispensable requirement for them in their lives. In order for patients and their families to cope with this very difficult disease process, it is thought that providing them with a higher level of psychological support will be beneficial in coping with the disease effectively. © The Author(s) 2025
Navigating stress with creativity: The moderating role of conflict-induced creativity on job satisfaction among entrepreneurs
No full textBackgroundEntrepreneurs frequently encounter high levels of job stress, which can undermine their job satisfaction. Although the negative consequences of stress are well-known, less attention has been paid to the role of Conflict-Induced Creativity in buffering these effects.ObjectiveThis study investigates how Conflict-Induced Creativity moderates the relationship between job stress and job satisfaction among entrepreneurs, addressing a gap in understanding adaptive mechanisms in high-pressure work environments.MethodsUsing a quantitative design, data were collected from 453 entrepreneurs through convenience sampling. Statistical analyses included factor analyses, correlations, regressions, and moderation testing via PROCESS MACRO in SPSS v.22.ResultsValidated scales assessed job satisfaction (α = 0.934), job stress (α = 0.919), and Conflict-Induced Creativity (α = 0.832). Job stress negatively predicted job satisfaction (β = -0.126, p < 0.001), while Conflict-Induced Creativity emerged as a strong positive predictor (β = 0.688, p < 0.001). Moderation analysis confirmed that Conflict-Induced Creativity significantly buffered the adverse effects of stress on satisfaction (b = 0.147, 95% CI [0.048, 0.245], p < 0.05).ConclusionConflict-Induced Creativity plays a protective role in stressful entrepreneurial contexts. Practically, fostering a work culture that supports Conflict-Induced Creativity can enhance resilience and job satisfaction among entrepreneurs, offering actionable insights for leadership development, training programs, and organizational policy.4059893
The impact of high voltage transmission lines (HVTL) on property value: A descriptive initial survey
No full textProperties hosting High Voltage Transmission Lines (HVTL) generally have lower values in Turkey. Therefore, owners are compensated for the easement. However, due to the inadequacy of laws and regulations, easement prices (compensation) can be calculated incorrectly. In this study, a descriptive survey was conducted to obtain ideas and information on the solution of problems encountered in determining easement prices and practices in other countries were examined. As a result of the survey, the area covered by the easement on the property and the route of the line were identified as the most important factors that negatively affect property value. It emerges that the diagonal crossing of HVTL over properties is the factor that decreases property value the most (compared to other crossing methods). Additionally, it is observed that the easement price paid to property owners varies mostly according to the per square meter value of the property and secondly according to the area of the property. © 2025 Survey Review Ltd
Cyber incivility: the silent threat shattering teachers’ mental health and happiness at work. Does gender matter?
No full textThe COVID-19 pandemic brought significant changes to the education sector, forcing a rapid shift to distance learning that exposed teachers to new challenges, including cyber incivility. This study, grounded in the Conservation of Resources Theory, investigates how mental health problems mediate the relationship between cyber incivility and happiness at work, with gender as a moderating factor. Data were collected from 632 high school teachers in Türkiye, who participated in distance education, using hypothetical scenarios and analysed through the Hayes Process Macro Model 4 and Model 7. The findings reveal that mental health problems significantly mediate the impact of cyber incivility on workplace happiness, with gender moderating this relationship. Specifically, female teachers experienced more mental health issues due to cyber incivility compared to their male counterparts. This research highlights the harmful effects of cyber incivility on teachers’ mental health and provides critical insights for developing policies to address these challenges. The study emphasises the importance of supporting teachers’ well-being amidst the ongoing digitalisation of education. By addressing these issues, the study contributes to a better understanding of the complexities educators face in the evolving digital landscape. © 2025 Informa UK Limited, trading as Taylor & Francis Group
