Öğe Türü: Öğe , An Examination of the Personality Traits and Sense of Humour of Paralympic Athletes(Cracow Tertium Society for the Promotion of Language Studies, 2026) Atasoy, Taner; Yılmaz, AtikeThe aim of this study is to examine the personality traits and humour styles of Paralympic athletes. The relational screening model was used in the study, and 292 Paralympic athletes were evaluated. The basic personality traits scale and humour styles scale were applied in the study. In the findings, while significant differences were detected in the sub-dimensions and total scores of the basic personality traits scale of Paralympic athletes in terms of gender, age, type of physical disability, degree of disability, sports branch, and sports background variables, no significant difference was detected in terms of the variables of education status and being a national athlete or not. While significant differences were detected in the subdimensions and total scores of the humour styles scale in terms of education status, sports branch, being a national athlete or not, and sports background variables, no significant difference was detected in terms of the variables of gender, type of physical disability, and degree of disability. In the study, it was concluded that, as per the sports branches the athletes participate in, the athletes’ personality traits and humour styles are effective in their personality development, that the non-national athletes adopt a self-enhancing humour style, and that the sports background is effective on personality traits and humour styles. In the relevance between personality traits and humour styles, it was inferred that athletes with an affiliative humour style exhibit positive personality traits, while athletes exhibiting negative personality traits tend to adopt self-defeating and aggressive humour styles.Öğe Türü: Öğe , Assessing the Gymaware RS Linear Position Transducer Reliability and Validity in Measuring Countermovement Jump Height(Routledge, 2026) Akyıldız, Zeki; Şentürk, DenizThis study evaluated the concurrent validity and intra-device reliability of a linear position transducer (LPT) for counter-movement jump (CMJ) height. Twenty-six subjects (22.21 ± 5.3 years) performed five CMJs using a force plate (Forcedecks) concurrently with the LPT to test validity. A statistically significant difference was found between the force plate and Gymaware units. Although there are differences between strength platforms and Gymaware units, there is no difference between the Gymaware units. Bland-Altman analysis for validity revealed that LPT overestimated jump height for CMJ in both units, Gymaware RS unit 1 and Gymaware RS unit 2. Gymaware RS equipment, like the force platform, provides reliable measurement data. The Forcedecks force platform, Gymaware RS unit 1, and Gymaware RS unit 2 provide data below 5% CV. The Gymaware RS overestimates jump height, but it is a reliable tool for tracking changes in jump height to measure performance improvement and monitor fatigue.Öğe Türü: Öğe , The Effect of Hope and Awareness on the Decoding of Climate Change Information Accessed on the Internet(Ljubljana University, Faculty of Social Sciences, 2026) Savaş, Sezgin; Tunçay, Esra; Ilıcak Aydınalp, Şükran Güzin; Kılıç, BüşraThe main purpose of this article is to reveal the connection between the way of decoding information about climate change and the level of awareness and hope possessed by individuals. In this context, a research model that includes hope, awareness and decoding is used. Data were obtained from a sample of 383 people in the research. While the relationship between the research variables was examined with correlation analysis, the effect of independent variables on the dependent variable was examined with regression analysis. Difference tests were also performed. Results of the correlation analysis showed that decoding had positive weak and moderate relationships with hope and awareness, respectively. When considering the regression analysis results, it is striking that although awareness positively predicts decoding, a sub-dimension, Recklessness Act to Climate Change, negatively predicts it. The difference tests reveal that hope only includes the average difference of the sub-groups in terms of the education categorical variable. In this sense, education can be considered an important determinant in terms of hope.Öğe Türü: Öğe , Optimizing Nanoclay-Enhanced Membranes for Oil Rejection Using Response Surface Methodology(John Wiley and Sons Ltd, 2026) Gül, Ayşe; Şenol Arslan, Dilek; Barış, Mesut; Boyraz, Pınar; Alibaz, Name NurThe efficient separation of waste oil from contaminated water is critical due to its challenges in environmental and industrial applications. This study investigated the production and optimization of polysulphone (PSF) membranes using two different types of clay (nanomer clay/CN and commercial nanoclay/NC). Response Surface Methodology (RSM) was applied to optimize the basic production parameters and nanoclay concentrations systematically to maximize oil rejection and permeability flow. The experimental results showed that NC and CN significantly increased the hydrophilicity, permeability, and fouling resistance of the membrane compared to pure PSF membranes. The contact angle significantly decreased from 64.34 (pristine PSF) to 36.23 (2% NC), indicating highly improved hydrophilicity. Consequently, the pure water flux increased from 177.2 L/m2 h to a maximum of 248.6 L/m2 h (1% NC). Furthermore, the modified membranes exhibited outstanding anti-fouling properties; the flux recovery ratio (FRR) improved from 88.09% to 96.20% (1% CN), while the decline ratio (DR) drastically dropped from 60.89% to 32.14%. The optimized condition for maximum removal efficiency using a modified quadratic model revealed that 2572 mg/L oil can be treated with a PSF membrane containing 2.0% CN to remove 98.271% of the oil. The model also suggests superiority of CN over NC with desirability factors of 0.978 and 0.900, respectively, while both demonstrated high efficiency. This theoretically modeled experimental comparative study highlights the importance of PSF membrane technology for efficient and sustainable oil–water separation and demonstrates the promising potential of nanoclay modifications.Öğe Türü: Öğe , Challenges to Attaining the SDG 2 (Zero Hunger) and Future Projections: The Criticality of Types of Corruption, Human Rights, and Greenhouse Gas Emissions for Selected Asian Countries(John Wiley and Sons Ltd, 2026) Çelik, Ali; Köstekçi, Ahmet; Orhan, Ertuğrul Buğra; Yıldız, AbdunnurBy the mid-21st century, the global economic system had not yet fully solved the problem of hunger. Therefore, achieving SDG 2 (Zero Hunger), one of the UN’s Sustainable Development Goals (SDGs), is crucial. This study therefore aims to examine the factors that may lead to hunger in seven selected Asian countries (Afghanistan, Bangladesh, North Korea, India, Pakistan, Papua New Guinea, and Timor-Leste) between 2002 and 2022. In this context, Panel-robust estimation results have shown that rising executive corruption is a major driver of hunger. However, remarkably, hunger decreases when public sector corruption (PC) and judicial corruption (JC) boost. Another important finding is that progress in gross domestic product (GDP), human rights, and democracy play a significant role in reducing hunger. Conversely, as expected, population growth and rising greenhouse gas emissions (GHG) were found to be other factors that trigger hunger. Ridge regression results supported the other findings and also revealed that a decrease in legislative corruption (LC) triggered hunger. The results of the interaction terms indicated that an increase in Publiccorruption × Humanrights, Publiccorruption × Democracy, Executivecorruption × Humanrights and Executivecorruption × Democracy led to a reduction in hunger, while a rise in Legislativecorruption × Humanrights and Legislativecorruption × Democracy led to an increase in hunger. These results are important for policymakers, governments and countries aiming to achieve SDG 2, as they can inform policy design and proactive interventions utilizing empirical findings.
