The relationship between superiority complex and the selection of aggressive dog breeds
Lisansüstü Eğitim Enstitüsü, Psikoloji Ana Bilim Dalı, Psikoloji Bilim DalıBu araştırma, Alfred Adler'in Bireysel Psikoloji teorisine dayanarak, üstünlük kompleksinin İstanbul'da yaşayan bireylerin agresif köpek tercihi üzerindeki etkisini incelemektedir. Bu bağlamda araştırma sorusu, "Üstünlük kompleksinin köpek tercihleri üzerindeki etkisi nedir?" olarak belirlenmiş ve karma metodoloji kullanılarak ele alınmıştır. Nicel anketler ve nitel mülakatlar yoluyla toplanan veriler, üstünlük kompleksi taşıyan katılımcıların tercihlerinin ardındaki motivasyonları ortaya çıkarmıştır. Araştırmanın bulguları, katılımcıların agresif köpekleri tercih etmelerinde cesaret ifadesi, kişisel farklılık deneyimi, dominasyon arzusu ve toplumsal normlara tepkinin etkili olduğunu göstermiştir. Bu bulgular, bireylerin köpek tercihlerinin, sadece fiziksel güvenlik ihtiyaçlarından değil, aynı zamanda psikolojik ve sosyal faktörlerden de etkilendiğini ortaya koyarak, üstünlük kompleksinin bu tercihlerde ne derecede rol oynadığını anlamamıza yardımcı olmaktadırThis research, grounded in Alfred Adler's Individual Psychology theory, examines the impact of the superiority complex on the preference for aggressive dog breeds among individuals living in Istanbul. The research question, "What is the effect of the superiority complex on dog breed preferences?" has been addressed using a mixed methodology. Data collected through quantitative surveys and qualitative interviews have revealed the motivations behind the choices of participants with a superiority complex. The findings indicate that the expression of courage, experiences of personal distinction, desires for domination, and reactions to social norms are influential in their preference for aggressive dogs. These insights demonstrate that individuals' dog breed preferences are influenced not only by needs for physical security but also by psychological and social factors, thereby aiding our understanding of the extent to which the superiority complex plays a role in these choices
Electromagnetic properties of vector doubly charmed tetraquark states
We conduct a systematic study of the electromagnetic properties of multiquark systems with undetermined internal structures. Motivated by the recent observation of the T+cc state, we apply the light-cone version of the QCD sum rule method to extract the magnetic dipole moments of several possible doubly charmed vector tetraquark states. When analyzing the magnetic dipole moment of these states, they are modeled to have the diquark-antidiquark configurations. The magnetic dipole moments for the members are extracted as and mu Tccss = 1.44+0.53-0.41 mu N. Comparing the results obtained for the magnetic dipole moments of the Tccu d state with the Tccu s state, the U symmetry is seen to be broken at about 15%, while, for the Tccdd and Tccss states, this symmetry is minimally broken. The obtained results may be useful to determine the true nature of these new interesting states.Iran National Science Foundation (INSF) [4025036]K.

Compression behavior of sheet-network triply periodic minimal surface metamaterials as a function of density grading
This study involved the fabrication and experimental testing of five distinct geometries of triply periodic minimal surface (TPMS) cellular structures characterized by uniform and relative density grading. The specific geometries examined were Schoen-Gyroid, Schwarz-Diamond, Schoen-I-WP, Schwarz-Primitive, and Fischer-Koch S. The experimental tests focused on subjecting these structures to compression loads. Samples were produced with a masked stereolithography (MSLA) printer. The samples had initial and end volume fractions (VFs) ranging from 20% to 60% in increments of 10%, with five varied relative densities. The Taguchi method is utilized to determine the optimal testing parameters, while the Analysis of Variance (ANOVA) test is employed to examine the data. The novelty of this paper is to comprehensively investigate the structural efficiency and versatility of TPMS for various applications by optimizing five different functionally graded TPMSs. The ANOVA findings highlighted the substantial impacts of Initial VF, Final VF, and TPMS type on the observed fluctuations in stress at the first peak. The Initial VF made a significant contribution, demonstrating 28.8% higher effectiveness than the Final VF. The TPMS type had a statistically significant effect on the amount of energy absorbed, revealing that different lattice types have abilities to absorb energy.Karabuk University Scientific Research Projects Coordination Unit [KBUBAP-23-ABP-069]The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This work was supported by Karabuk University Scientific Research Projects Coordination Unit.

Development and validation of the metaverse perception scale for nursing students
Background: The use of Metaverse applications in nursing education is increasing every day and the evaluation of nursing students' perceptions of this new digital technology may guide interventions related to the use of the Metaverse. However, currently, no standardized instrument specifically designed to measure nursing students' perceptions of the Metaverse exists in Turkey. Aim: To develop and validate the Metaverse Perception Scale for Turkish nursing students. Method: This methodological study was carried out between March 1, 2023 and June 30, 2023 and its sample consisted of 770 nursing students who were enrolled in undergraduate nursing departments of universities in Turkey. The item pool was created based on a literature review and data were analyzed using descriptive statistics, item analysis, exploratory and confirmatory factor analysis, convergent and divergent validity, correlation analysis, internal consistency reliability and test-retest analysis. Results: The content validity index for the items ranged between 0.85 - 1.00. According to exploratory factor analysis, the eigenvalue of four factors was greater than one. These four factors explained 77.28 % of the total variance. In the scale model developed for this study, model fit was found to be acceptable for goodness of fit index:.921 and root mean square error of approximation:.064. chi 2/sd: 1.659, normalized fit index:.961 and chisquare/degree of freedom revealed that model fit was at a good level and within the recommended value ranges. It was determined that the scale showed convergent and divergent validity and Cronbach's Alpha value ranged between 0.95 and 0.93 in the subscales. The Metaverse Perception Scale in Nursing Students was found to have a high level of test-retest reliability. Conclusion: This study showed that the scale, which consists of 24 items and four subscales, is a valid and reliable measurement tool that can be used to assess nursing students' perceptions of the Metaverse in the Turkish context. This scale can contribute to the evaluation of Turkish nursing students' perceptions of the Metaverse, as well as the effective management of processes related to Metaverse practices
Thermomechanical properties of confined magnetic nanoparticles in electrospun polyacrylonitrile nanofiber matrix exposed to a magnetic environment: structure, morphology, and stabilization (cyclization)
Electrospun metal oxide-polymer nanofiber composites hold promise for revolutionizing biomedical applications due to their unique combination of electronic and material properties and tailorable functionalities. An investigation into the incorporation of Fe-based nanofillers for optimizing the polyacrylonitrile matrix was conducted, where the systematic and organized arrangement of inorganic components was achieved through non-covalent bonding. These carefully dispersed nanomaterials exhibit the intrinsic electronic characteristics of the polymers and concurrently respond to external magnetic fields. Electrospinning was utilized to fabricate polyacrylonitrile nanofibers blended with Fe2O3 and MnZn ferrite nanoparticles, which were thermomechanically, morphologically, and spectroscopically characterized in detail. With the application of an external magnetic field in the course of dynamic mechanical measurements under tension, the storage modulus of the glass transition Tg of PAN/Fe2O3 rises at the expense of the loss modulus, and a new peak emerges at similar to 350 K. For the PAN/MnZn ferrite nanofibers a relatively larger shift in Tg (from similar to 367 K to similar to 377 K) is observed, emphasizing that in comparison to Fe2O3, Mn2+ ions in particular enhance the material's magnetic response in MnZn Ferrite. The magnetic oxide particles are homogenously dispersed in polyacrylonitrile, corroborated by high-resolution scanning electron microscopy. Both nanopowder additions lead to a slight shift of the peak towards larger angles, related to the shrinkage of the polymer. Produced nanofibers with high mechanical and heating efficiency can optimize the influence of the intracellular environment, magnetic refrigeration systems and sensors/actuators by their magnetic behavior and heat generation. The incorporation of Fe-based nanofillers for the optimization of the nanofiber of polyacrylonitrile matrix was achieved through non-covalent bonding. Produced nanofibers can optimize the influence of the intracellular environment.Universitt Wien [E-COST-GRANT-CA21101-28134500]; COST Action CONTEXT [CA17107]; COST (European Cooperation in Science and Technology); University of ViennaWe would like to thank for the Short-Term Scientific Mission (STSM) grant (E-COST-GRANT-CA21101-28134500) for ASS between 29/09/2023 -08/10/2023 by the Prof. Dr Wilfried Schranz (Host Institution Faculty of Physics, Physics of Functional Materials, University of Vienna).

Prediction of daily global solar radiation in different climatic conditions using metaheuristic search algorithms: a case study from Türkiye
Today’s many giant sectors including energy, industry, tourism, and agriculture should closely track the variation trends of solar radiation to take more benefit from the sun. However, the scarcity of solar radiation measuring stations represents a significant obstacle. This has prompted research into the estimation of global solar radiation (GSR) for various regions using existing climatic and atmospheric parameters. While prediction methods cannot supplant the precision of direct measurements, they are invaluable for studying and utilizing solar energy on a global scale. From this point of view, this paper has focused on predicting daily GSR data in three provinces (Afyonkarahisar, Rize, and Ağrı) which exhibit disparate solar radiation distributions in Türkiye. In this context, Gradient-Based Optimizer (GBO), Harris Hawks Optimization (HHO), Barnacles Mating Optimizer (BMO), Sine Cosine Algorithm (SCA), and Henry Gas Solubility Optimization (HGSO) have been employed to model the daily GSR data. The algorithms were calibrated with daily historical data of five input variables including sunshine duration, actual pressure, moisture, wind speed, and ambient temperature between 2010 and 2017 years. Then, they were tested with daily data for the 2018 year. In the study, a series of statistical metrics (R2, MABE, RMSE, and MBE) were employed to elucidate the algorithm that predicts solar radiation data with higher accuracy. The prediction results demonstrated that all algorithms achieved the highest R2 value in Rize province. It has been found that SCA (MABE of 0.7023 MJ/m2, RMSE of 0.9121 MJ/m2, and MBE of 0.2430 MJ/m2) for Afyonkarahisar province and GBO (RMSE of 0.8432 MJ/m2, MABE of 0.6703 MJ/m2, and R2 of 0.8810) for Ağrı province are the most effective algorithms for estimating GSR data. The findings indicate that each of the metaheuristic algorithms tested in this paper has the potential to predict daily GSR data within a satisfactory error range. However, the GBO and SCA algorithms provided the most accurate predictions of daily GSR data. © The Author(s) 2024.Türkiye Bilimsel ve Teknolojik Araştırma Kurumu, TÜBİTA

Therefore, the hypothesis of the study are that there are statistically significant relationships between the coping styles and anxiety levels; the coping styles and academic achievement; anxiety levels and the academic achievement in the high-school students who are brothers or sisters. Another aim of this study is to determine whether the anxiety levels, coping styles and the academic achievement indicate a significant correlational relationship with the variables of age, sex, grade, the number of brothers or sisters, birth order, family structure and the place of living in the students. The sample of the study consists of 430 high-school students. Sociodemographic data form, Beck Anxiety Scale, Coping Styles Scale for Children and Adolescents were used to collect data using an online survey. The statistical analysis of the study was conducted using SPSS 25 (Statistical Package for the Social Sciences). The relationships between the anxiety levels, coping styles and the academic achievement were also investigated. Findings of this study indicated that Beck anxiety levels were found to be negatively correlated with the coping styles; anxiety levels were found to be negatively correlated with the active and avoidant coping styles and anxiety levels were found to be positively correlated with the negative coping style. Besides, there was a significant correlational relationship between the academic achievement and the coping styles. As the students get higher scores from the anxiety scale, the scores they get from the academic achievement scale becomes lower. Findings of this study were discussed in the light of the literature and the suggestions for future researches were given and the reference was made to the clinical practise
Decays of fully beauty scalar tetraquarks to BqBq and B*qB*q mesons
Decays of the fully beauty four -quark structures X4b and T4b to B meson pairs are investigated in the framework of the QCD three-point sum rule method. We model the scalar exotic mesons X4b and T4b as diquark-antidiquark systems composed of the axial-vector and pseudoscalar diquarks, respectively. The masses m = (18540 +/- 50) MeV and m similar to = (18858 +/- 50) MeV of these compounds calculated in our previous articles fix possible decay channels of these particles. In the present work, we consider their decays to BqB over bar q and B*qB over bar *q (q = u, d, s, c) mesons. In the case of X4b, the mass of which is below the 2 eta b threshold, these channels determine essential part of its full width Gamma 4b. The tetraquark T4b can decay to the pair eta b eta b; therefore, partial widths of processes with B(B*) mesons in the final state permit us to refine our estimate for the full width of this particle. The predictions Gamma 4b = (9.6 +/- 1.1) MeV and Gamma similar to Full 4b = (144 +/- 29) MeV obtained in this article can be used in future experimental investigations of four b -quark mesons.Iran National Science Foundation (INSF) [4025036]K.
