    The interplay between progressivism and logical fallacy: implications for climate change communications
    (Iop Publishing Ltd, 2025) Demir, Mehmet Ozer; Demir, Zuhal Gok; Erendag Sumer, Fulya; Karakaya, Cigdem; Aydogan, Hediye; Arslan, Burak
    The spread of fake news and the influence of moral reasoning on public opinion present significant challenges in climate change communication. This study examines how the ideological underpinnings of conservatism and liberalism, combined with logical fallacies and fake news, shape public perceptions of climate change. Using the Moral Foundations Questionnaire (MFQ), and a quantitative online survey of 288 participants, we assess whether individuals identified as liberal or conservative are more prone to accept flawed reasoning. Results show that conservatives are significantly more susceptible to a broader range of logical fallacies, including emotional manipulation, appeals to authority, and oversimplified arguments-patterns commonly associated with fallacies such as Argumentum ad hominem, Straw Man, and Tu quoque. Meanwhile, liberals, though less vulnerable overall, are particularly influenced by specific fallacies which align with their moral focus on harm and fairness. The findings offer new insights into the intersection of moral psychology, political ideology, and misinformation, with practical implications for designing ideologically tailored climate change messages.

    The Impact of Parents' Digital Awareness on their Digital Attitude Behaviors
    (Taylor & Francis Inc, 2025) Teke, Busra; Ayar, Dijle
    In today's world, in which technology has become an inseparable part of daily life, the use of digital technology is increasingly common among children. It is important to investigate the topic of digital technology use, which can affect children's social, emotional, psychological, mental, and physical development in many ways, as well as the reasons that can influence the characteristics they should possess. This study was conducted to evaluate the effect of parents' digital awareness on their digital attitude behaviors. This study was descriptive, cross-sectional and correlational. The study was conducted with parents (n = 545) Descriptive Information Form, Digital Parenting Awareness Scale and Digital Parenting Attitude Scale were used as data collection tools in the study. It was determined that there was a strong and negatively significant relationship between the mean total scores of the parents' digital attitude behaviors and digital neglect (r = -0.529, p < .001), strong negative significant relationship (r = -0.643, p < .001) between the mean scores of parents' digital attitude behaviors and negative modeling sub-dimension (r = -0.643, p < .001). It was determined that there was a strong negative significant relationship between parents' digital attitude behaviors and the condition of being a negative role model, a moderate negative significant relationship with the condition of digital neglect, a moderate positive significant relationship with the condition of efficient use, and a moderate positive significant relationship with the condition of risk protection.

    Particle stabilised high internal phase emulsion scaffolds with interconnected porosity facilitate cell migration
    (Iop Publishing Ltd, 2025) Munive-Olarte, Areli; Durgut, Enes; Verbruggen, Stefaan W.; Claeyssens, Frederik; Reilly, Gwendolen C.
    A key challenge in bone tissue engineering (BTE) is designing structurally supportive scaffolds, mimicking the native bone matrix, yet also highly porous to allow nutrient diffusion, cell infiltration, and proliferation. This study investigated the effect of scaffold interconnectivity on human bone marrow stromal cell (BMSC) behaviour. Highly interconnected, porous scaffolds (polyHIPEs) were fabricated using the emulsion templating method from 2-ethylhexyl acrylate/isobornyl acrylate (IBOA) and stabilised with similar to 200 nm IBOA particles. Pore interconnectivity was tuned by varying the internal phase fraction from 75%-85% and characterised by the degree of openness, Euler number, frequency, and size of pore interconnects. The attachment, proliferation, infiltration, and osteogenic differentiation of the BMSC cell line (Y201) were evaluated on these scaffolds. Results showed that high pore interconnectivity facilitated diffusion and cell infiltration throughout the scaffolds. Furthermore, the most interconnected scaffolds enhanced osteogenic differentiation of Y201 cells, as evidenced by elevated alkaline phosphatase activity and increased calcium and collagen production compared to less interconnected scaffolds. These findings emphasise the importance of scaffold interconnectivity in BTE for efficient nutrient transport, facilitating cell migration and infiltration, and supporting the development of interconnected cell networks that positively influence osteogenic differentiation.

    The Effect of Psychological Distress and Intimate Partner Violence on Treatment Adherence in the Mothers of Children with Attention Deficit Hyperactivity Disorder
    (Routledge Journals, Taylor & Francis Ltd, 2025) Kocaman, Orhan; Tekin, Ugur; Yilmaz, Semra; Ok, Sena Saygili
    This study examines the effects of maternal psychological distress and the Intimate partner violence (IPV) to which mothers are exposed on treatment adherence. 55 mothers of children diagnosed with ADHD and 51 mothers of healthy children were included in the study. Psychological distress and IPV were greater in the mothers of children with ADHD than in those of healthy children. Greater IPV was determined in the low treatment adherence group among the mothers of children with ADHD than in the moderate-high adherence. Holistic approaches in ADHD in which the mother's mental health is included can increase adherence to treatment.

    Investigation of the electrochemical behaviors of fibers containing new pyrazolo[5,1-c][1,2,4]triazine derivatives
    (Taylor & Francis Inc, 2023) Maslakci, Neslihan Nohut; Eren, Esin; Dulgerbaki, Cigdem; Yildirim, Fati; Oksuz, Aysegul Uygun
    Electrospun fibers of 7-methyl-4-phenyl-8-(4'-methoxy)phenylazopyrazolo[5,1-c][1,2,4]triazine-3-carboxylic acid ethyl ester (PCA-4) and 7-methyl-4-phenyl-8-(2'-methoxy)phenylazopyrazolo[5,1-c][1,2,4]triazine-3-carboxylic acid ethyl ester (PCA-2) were produced using electrospinning technique. Poly(methylmethacrylate) (PMMA) was used as support electrospun polymer. The morphological and chemical characterizations of the PCA-4/PMMA and PCA-2/PMMA electrospun fibers were carried out by scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy analysis (SEM-EDX). The electrochemical behavior of the PCA-4/PMMA and PCA-2/PMMA fibers onto ITO electrodes was examined by cyclic voltammetry (CV) measurements. The new PCA-4/PMMA and PCA-2/PMMA fibers were used for phosphate anion sensing. PCA-4/PMMA fiber indicated the best current response to 0.2 M phosphate buffer solution at -0.67 V.

    Climate policy uncertainty and green bond markets
    (Iop Publishing Ltd, 2025) Gulal, Omer Serkan; Topcu, Mert; Emirmahmutoglu, Furkan; Daud, Abdikani Farah
    Using monthly data from July 2013 to April 2023, this study applies a time-varying causality approach to examine the relationship between climate policy uncertainty and the green bond market. During the episode December 2016 - December 2018, a negative bi-directional relationship is found, suggesting that higher green bond returns contributed to a reduction in policy uncertainty, fostering a more stable investment environment. However, during the COVID-19 pandemic, the relationship shifted, showing that increased green bond returns were associated with higher CPU, reflecting investor concerns about regulatory responses in times of crisis. Overall, the study emphasizes the importance of considering the time-varying nature of the CPU-green bond nexus while developing consistent and supportive climate policies to sustain the growth of green finance.

    Investigation of radiation shielding properties of CeO2 thin films prepared at different molarities
    (Iop Publishing Ltd, 2025) Kanmaz, Imran; Koksal, Oguzkagan; Apaydin, Gokhan; Tomakin, Murat; Cengiz, Erhan
    In this study, CeO2 thin films were produced using the spin coting method, which is one of the sol-gel methods, in six different molarities. X-ray diffraction (XRD) patterns revealed the characteristic peaks of the films, while Field Emission Scanning Electron Microscopy (FESEM) confirmed their homogeneous structure. Then, radiation shielding parameters like linear absorption coefficient (LAC), mass absorption coefficient (MAC), tent value layer (TVL), mean free path (MFP), and half value layer (HVL) were thoroughly examined. The results showed that increasing molarity had a significant effect on the thickness values of thin films and the absorption parameters were found to improve with increasing molarity. Both LAC and MAC values decrease as the energy level increases, but the increase in CeO2 molarity leads to a strong increase on these coefficients. The HVL value was also found to be 0.42 cm at the lowest energy of 14.957 keV and to be around 10 cm at the greatest energy of 59.543 keV (0.05 M). When the radiation energy applied to the material was raised from 14.957 keV to 59.543 keV, it was found that the MFP values of 0.05 M CeO2 thin films grew gradually from 0.61 cm to 14.51 cm. High energy radiation of 59.543 keV and a low density (0.05 M) medium resulted in peak TVL values of 33.423 cm, allowing the radiation to pass through the material with minimal interaction.

    Regressive autism with autoimmune encephalitis: case report and literature review of subtype of autism spectrum disorder
    (Taylor & Francis Ltd, 2024) Avsar, Pinar Aydogan; Kara, Tayfun; Kocaman, Orhan
    About one-third of individuals with autism spectrum disorder (ASD) show a sudden loss of acquired skills between the 2nd or 3rd years of life. The primary areas of loss were grouped into language skills, social interest, adaptive functioning, and motor skills. A 4-year and 2-month-old boy presented to the child and adolescent mental health and disease outpatient clinic with his parents with complaints of decreased eye contact, and regression in speech. His developmental milestones were within the typical range of three years and two months. During the investigation into the organic etiology of regression, serum anti-CASPR2 positivity was detected, and intravenous immunoglobulin administration was initiated. After 6 months of treatment and special education, there was a slight decrease in the CARS score along with improvements in adaptation to change, visual response, and non-verbal communication. This rare case of regressive autism accompanied by autoimmune encephalitis provides further evidence in the field that autoimmune encephalitis may influence the development of the regressive subtype of ASD. Differential diagnosis is crucial because additional immunotherapy may be beneficial in these cases. Further investigation is needed to identify the relationship.

    Foreign Direct Investments and Tourism: A Cross-Section Analysis
    (Routledge Journals, Taylor & Francis Ltd, 2023) Agazade, Seymur; Karasakaloglu, Burcu
    This study investigates the effect of foreign direct investments (FDI) on tourism using cross-sectional data for 135 countries and their high- and middle-income subgroups. The study takes three different tourism performance indicators into account: travel and tourism GDP, international tourism receipts, and international tourist arrivals. The findings support that FDI positively affects all three tourism performance indicators. Furthermore, this effect is observed to be at the highest level on the international tourism receipts and at the lowest level on travel and tourism GDP. These results indicate that FDI affects international tourism considerably more than it does domestic tourism; it also boosts the tourism sector of the host countries in terms of brand value or market power. In addition, the results for the high- and middle-income countries are in accordance with the theoretical expectations of neoclassical economics in that FDI affects tourism more in middle-income countries.

    (Taylor & Francis Inc, 2024) Kudubes, Asli Akdeniz; Zengin, Hamide; Ayar, Dijle; Bektas, Ilknur; Bektas, Murat
    This research was conducted as a descriptive and cross-sectional study to determine the effects of nursing students' liking of children and attitudes toward clinical practice on their comfort and worry levels in the pediatric clinic. The research was carried out with 270 nursing students who had already taken or were taking the child health and diseases nursing course. Data were collected using a Nursing Student Information Form, the Barnett Liking of Children Scale, the Nursing Students' Attitudes toward Clinical Practices Scale, and the Pediatric Nursing Student Clinical Comfort and Worry Assessment Tool. Mean values, percentage calculations, and linear regression analysis were used for the analysis of the research data. Participants' mean scores were 52.30 +/- 6.16 on the Barnett Liking of Children Scale, 103.72 +/- 19.35 on the Nursing Students' Attitudes toward Clinical Practices Scale, 15.61 +/- 3.74 on the comfort sub-dimension, and 11.63 +/- 4.32 on the worry sub-dimension of the Pediatric Nursing Student Clinical Comfort and Worry Assessment Tool. It was determined that the liking of children and attitudes toward clinical practice explained 43.6% of the clinical comfort level of pediatric nursing students in Model 1 and 45.2% of their clinical worry level in Model 2. It was determined that the liking of children and attitudes toward clinical practice significantly affected the comfort and worry levels of nursing students in the pediatric clinic.

    Determination of the effect of adhesive fillets and viscous damping on the dynamic response of aluminum honeycomb sandwich panels
    (Taylor & Francis Inc, 2024) Oktav, Akin
    The dynamic characteristics of an aluminum honeycomb sandwich panel are experimentally determined under free boundary conditions and the computational model is updated according to the experimental results. The study confirms that the adhesives used to bond the core and face sheets affect the dynamic response of the sandwich panel through the adhesive fillets formed between the face sheets and the core during the bonding process. The viscous damping of the structure is also determined by experimental modal analysis. It is observed that the results of the experimental and computational results agree well when the effects of adhesive fillets and viscous damping are considered. Furthermore, a dynamic response analysis under random vibration is conducted to reveal the differences between the results of the initial and the updated models.

    Does tourism source market structure affect international etc
    (Routledge Journals, Taylor & Francis Ltd, 2023) Agazade, Seymur
    This paper calculates tourism source market structure indicators and investigates their impact on the international tourism demand for Antalya of Turkey. Tourism source market structure may influence tourism demand depending on its consequences regarding competitiveness and risk structure. To determine this influence, this paper estimates tourism demand functions within the framework of the two-stage system generalized method of moments (GMM). The tourism source market structure variables were calculated by considering the number of tourists by nationality and the estimations are based on the datasets of 37 source countries for 2001-2019 years. According to the calculated market structure indicators, the tourism source market concentrated in the early 2000s and diversified in the last years of the research period. Findings of the system GMM indicated that the tourism source market concentration boosts and diversification weakens the tourism demand for Antalya. In other words, tourism demand, which comes predominantly or intensively from a small number of countries, increases this demand.

    Parameters and barriers affecting the marketability of energy efficient residential buildings: a case study in Turkey
    (Taylor & Francis Ltd, 2024) Aydin, Yusuf Cihat; Mirzaei, Parham A.
    The data indicate that merely improving energy efficiency within energy-efficient buildings (EEBs) is insufficient to significantly reduce the energy demand of the building sector. To achieve substantial reductions, strategies must also focus on increasing the number of EEBs within the existing building stock. However, research in this area remains limited. Therefore, this study aims to explore the current market demand and barriers for EEBs, examine the impact of various design decisions on housing prices, identify the factors influencing the marketability of residential buildings, and analyze customer purchasing decisions in Turkey (T & uuml;rkiye). For this purpose, a comprehensive literature review was first made. It was observed that factors such as macroeconomic conditions, sales price, housing opportunities, location, brand, customer demographics, energy efficiency, housing features, and aesthetics were frequently discussed in the literature. Based on the literature review and preliminary study results, among other factors, aesthetic appreciation is considered the most applicable design strategy, and windows and balconies are identified as building components that can simultaneously affect energy efficiency, marketability, and aesthetics. Then, as a preliminary study to determine major marketing strategies, the housing marketing strategies were surveyed and analyzed from the real estate sector in different cities as provided in the advertisements posted on their websites. Furthermore, a comprehensive e-mail survey was conducted with 351 different real estate companies amongst 22 cities of T & uuml;rkiye. Based on the findings, enhancing architectural designs could potentially elevate the perceived value of energy-efficient homes by up to 18% among consumers and this can increase the marketability.

    Association of ANKK1 and DRD2 gene polymorphisms with exercise addiction among elite athletes
    (Routledge Journals, Taylor & Francis Ltd, 2025) Yildiz, Yeliz A.; Kasakolu, Anil; Bulgay, Celal; Biyikli, Turker; Kazan, Hasan H.; Koncagul, Seyrani; Bayraktar, Isik
    Exercise addiction is a behavior that may dysregulate athletic performance, and social and professional interactions of athletes. Whereas environmental factors including training routines and personal traits could contribute to exercise addiction, recent studies have emphasized the importance of genetic predisposition, leading to development of a subfield known as sports psychogenetics. In sports psychogenetics, ankyrin repeat and kinase domain containing 1 (ANKK1) and dopamine receptor D2 (DRD2) genes, located on chromosome 11 in a close proximity, have attracted research interest due to their involvement in dopaminergic signaling playing a crucial role in reward processing, motivation, cognition and behavior. Therefore, the present study aimed to investigate potential associations between 14 polymorphisms in ANKK1/DRD2 and exercise addiction among elite badminton players (n = 39) and elite wrestlers (n = 68). Exercise addiction was assessed using a psychometric screening instrument and allele frequencies of the selected polymorphisms were analyzed through genotyping with a single nucleotide polymorphism (SNP) microarray. Results indicated that two SNPs, rs7118900 and rs4436578, were significantly and independently associated with exercise addiction. Rs7118900 has previously been associated with an increased risk of drug addiction, neuroticism, and depressed effect whereas rs4436578 has been associated with neuroticism. In addition to those SNPS, rs2283265 and rs1125394 SNPs were also linked to exercise addiction in a branch-independent manner. Therefore, it is proposed that these SNPs could serve as genetic markers for identifying individuals at high risk of exercise addiction among athletes. However, further research is needed to understand the involvement of these SNPs in exercise addiction more comprehensively.

    Molecular investigations on T cell subsets in patients affected by hypomorphic DCLRE1C mutation
    (Taylor & Francis Ltd, 2025) Karaselek, Mehmet Ali; Duran, Tugce; Kuccukturk, Serkan; Hazar, Esra; Dogar, Oznur; Kiykim, Ayca; Guner, Sukru
    ObjectiveIn this study, we explored the expression of transcription factors, cytokines, and co-stimulatory molecules within the helper T (Th) cell subsets (Th1, Th2, Th17, and Treg) of patients with hypomorphic DCLRE1C gene mutations. MethodsThe study comprised eight patients and five controls. Transcription factor and cytokine expressions of Th subsets and co-stimulatory molecules were investigated by qPCR and flow cytometric following T cell stimulation. The findings were compared between patients (non-HSCT) and with hematopoietic stem cell transplantation (HSCT). ResultsFlow cytometric analyses; while the Treg rate was significantly lower in non-HSCT than in controls (p = 0.010), the IFN-gamma rate was significantly higher in patients than in the control and HSCT groups (p = 0.016, p = 0.022, respectively). Co-stimulatory molecule expressions were significantly lower in non-HSCT than in control (p < 0.001), and there was a significant improvement after HSCT. Post-stimulation qPCR analysis, significant changes were detected in non-HSCT/control, non-HSCT/HSCT, and HSCT/control comparisons. ConclusionsOur study is the first study to molecularly investigate Th cell subsets in hypomorphic DCLRE1C patients. It was determined that abnormalities in Th cell subsets still persisted despite HSCT. There are still many conditions to be explained in these patients, and we believe that our study may shed light on future studies.

    Evaluation of primary markers of inflammation and the systemic inflammation index in specific learning disabilities
    (Taylor & Francis Ltd, 2024) Avsar, Pinar Aydogan; Kara, Tayfun; Kocaman, Orhan; Akkus, Merve
    Aim: Specific learning disorder (SLD) is a term that refers to reading, writing and arithmetic difficulties. The neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) and systemic inflammation index (SII) are affordable and accessible inflammatory biomarkers. This research aims to evaluate the relationship between NLR, PLR, SII and SLD to determine whether inflammation contributes to pathogenesis. Methods: This study included 90 SLD-diagnosed patients and 90 age-, sex- and ethnicity-matched healthy controls. Blood cell counts and NLR, PLR and SII values were obtained from medical records and compared between the two groups. Results: The NLR, PLR and SII were significantly higher (p = 0.029, p = 0.033 and p = 0.018 respectively) and lymphocyte counts were significantly lower (p = 0.041) in the SLD group. WISC-R total scores decreased with age in the SLD group (-1.988 coefficient, Beta = -0.247 beta, p = 0.041). Multivariate logistic regression analysis revealed that the SII was the only parameter independently associated with the diagnosis of SLD (Beta = 0.003, p = 0.023). Conclusion: Inflammation might play a role in SLD etiopathogenesis. NLR, PLR and SII may be potential biomarkers for SLD in children. Further research may lead to early diagnosis and additional anti-inflammatory pharmacological therapies for SLDs.

    Dynamic response optimization of a thermoplastic composite sandwich beam under random vibration
    (Taylor & Francis Inc, 2024) Oktav, Akin; Basaran, Murat Alper; Daricik, Fatih
    The dynamic response of a thermoplastic composite sandwich structure is optimized under random vibration. First, the experimental modal analysis data of a set of test samples are processed by a sequential set of statistical analysis such as descriptive statistics, factor analysis, and paired sample t-test. Then, the sample with the highest ability to represent the group is taken as the reference data. Three different computational models, which are defined according to whether the solid to be meshed is considered an area or a volume, are constructed. Modal analysis results of the computational models are compared to the reference experimental data to evaluate the performance of the models. To predict the dynamic response of the sandwich beam, it is excited through a random signal in the transverse direction. The nodal acceleration responses are computed in 17 evenly spaced points located on the upper finishing layer of the sandwich beam. Finally, a geometry optimization study is conducted to predict the optimum thicknesses of the 7 layers bonded together to form the sandwich beam. The optimum layer thicknesses that minimize the nodal accelerations at 17 evenly spaced points on the sandwich beam are computed. The current study shows that the shell model has the closest values to the experimental data compared to other models. As far as the dynamic response of a TPC sandwich structure is concerned, it is concluded that the shell model better represents the structure during the modeling phase and leads to concurrently reduced weight and nodal acceleration, when optimized.

    A preliminary study on patulin contamination in spirit drinks
    (Taylor & Francis Ltd, 2022) Golge, Ozgur; Yenisehirlioglu, Emirhan; Kabak, Bulent
    A total of 120 spirit drinks and 40 apple juices were collected between 2018 and 2020 in three regions of Turkey and analysed by high-performance liquid chromatography coupled with a photodiode array detector (HPLC-PDA) for the incidence of patulin. The analytical method was successfully validated for both matrices. In 26.7% of apple juice samples, patulin was quantified at levels between 5.8 and 66.4 mu g L-1. Only one regulatory level exceedance was identified for apple juice. The mean dietary exposure of the adult population to patulin ranged from 0.083 to 0.091 ng kg(-1) bw day(-1). With the HPLC-PDA method, patulin was measured in quantifiable concentrations in 11 out of 25 cognac, 5 out of 40 liqueur, and 1 out of 10 whisky samples, up to a level of 42.6 mu g/l, whereas all vodka samples were free from patulin. In only one liqueur sample, the presence of patulin could be confirmed with LC-MS/MS, at a level of 8.9 mu g L-1.

    Is there a global trend toward better energy structure? Convergence analysis of energy diversification
    (Taylor & Francis Inc, 2026) Agazade, Seymur
    Energy diversification can be seen as an effective strategy to cope with energy security risks, environmental sustainability concerns and increasing energy demand. On the other hand, convergence of energy diversification across countries is linked to the foundation of global cooperation, which is essential to prevent environmental degradation. In this regard, this study calculates energy diversification for 135 countries and examines convergence in this diversification for these countries and their different subgroups. Findings supported convergence for all country groups and indicated low convergence rates. This result points to the difficulties of switching energy systems used by current production structures. Furthermore, the convergence rate was found to be relatively higher in middle-income countries compared to the low- and high-income ones. For low-income countries, this indicates weak motivations, market incentives and societal pressures in energy diversification. For high-income countries, on the other hand, low convergence speed points to the technological constraints of energy diversification. Finally, the findings show that fossil energy abundance alone does not make a difference in energy diversification. Therefore, taking the structure of the energy sector and power of conventional energy firms into account in government support or policy measures for diversification may be useful to achieve low-carbon energy transition.
