Examining education for sustainable development in higher education to promote education for social justice in ChatGPT
(IGI Global, 2025) Keleş, Özgül
Generative AI can be employed as an effective instrument for the identification of the learning objectives that must be achieved in order to attain the Sustainable Development Goals (SDGs). Therefore, this research aims to answer these main research questions: (1) How does ChatGPT respond to issues (key competences, learning objectives, key pedagogical approaches, role of the artificial intelligence application ChatGPT) related to Education for Sustainable Development in higher education to promote Education for Social Justice?(2) Are the answers and suggestions provided by ChatGPT in line with the learning objectives of the UNESCO Education for Sustainable Development Goals (2017)? and (3) How was ChatGPT used in this study and what are the researcher's thoughts about its use as a research tool? An exploratory research method is used in this study. In this context, it aims to document experiences with ChatGPT and to discuss possible implications. In order to ascertain the results, the ChatGPT outputs were subjected to a detailed analysis.
Howard Barker’s Brutopia: history in politics, politics in history
(Knowledge Hub Publishing Company Limited (Hong Kong), 2025) Öğünç, Banu
Howard Barker can be considered as one of the most prolific writers of the British stage who has written numerous plays as well as poetry and theoretical writings on drama. He is especially a significant name for political drama due to the strong political themes explored in his works. Brutopia: Secret Life in Old Chelsea, as its full name, is a historical play that combines political criticism together with Barker’s understanding of theatre in line with his Theatre of Catastrophe. In this play, Barker invites the audience and/or the readers to the fictionalised world of the play, decorated with the historical facts of Thomas More’s life and its timeline. Barker applies history to lay out the ground for social and political criticism of the contemporary society. He skilfully blends history with fiction in order to disturb the audience and/or the readers to make them think about the present. Consequently, this paper aims at analysing Brutopia within Barker’s creation of imaginary place as thinly disguised in history and focuses on social and political criticism that exemplifies Barker’s specific approach towards drama, Theatre of Catastrophe.
Lead-Free Na2ZrTeO6 double perovskite: a promising candidate for high-temperature and optoelectronic applications
(Wiley-VCH Verlag, 2025) Deligöz, Engin; Rached, D.; Özışık, H.; Caid, M.; Rached, Y.
The double perovskite class of materials is highly significant due to its optoelectronic properties and structural stability, making it ideal for applications in electronics, photovoltaics, and catalysis. We present a first principles study of the elastic, anisotropic mechanical, electronic, and optical properties of the newly synthesized double perovskite Na2ZrTeO6 compound. The calculated elastic constants confirm the mechanical stability of the compound. Na2ZrTeO6 exhibits high mechanical durability, a wide band gap, and significant anisotropic mechanical properties. The observed anisotropy suggests that Na2ZrTeO6 may exhibit direction-dependent mechanical and electronic behavior, making it a versatile material for advanced technological applications. The high Debye and melting temperature indicate that Na2ZrTeO6 may be very suitable for high-temperature processes, refractory materials, and high-temperature equipment. This compound is a semiconductor with a wide band gap and the electrons are mobile carriers because they have smaller effective masses. The optical properties, including the real and imaginary parts of the complex dielectric function, energy loss, real and imaginary parts of the refractive index, and absorption coefficient, are analyzed for photon energies up to 20 eV to evaluate the optical response.
The correlation between systemic immune-inflammatory index and helicobacter pylori infection and its severity
(Galenos Publishing House, 2025) Ordu, Melike; Öztürk, Gülfidan; Ergin, Mustafa
The systemic immune-inflammatory index (SII), derived from routine hemogram parameters, has recently emerged as a novel marker reflecting the balance between host immune status and inflammatory burden and may offer information about the severity of Helicobacter pylori (H. pylori) associated gastric inflammation. We investigated whether there was a correlation between H. pylori inflammation, its severity, and this index. Methods: This single-center, retrospective study was conducted between January and December 2021. A total of 1137 H. pylori-positive and 401 H. pylori-negative patients who underwent upper gastrointestinal endoscopy were included. Participants were grouped based on gastric tissue activity and chronicity scores, which reflect the histological severity of inflammation and mononuclear infiltration, respectively, as defined by the updated Sydney system. The SII and other inflammatory markers were statistically compared between groups. Correlation analysis was also performed to evaluate the relationship between histological severity and inflammatory parameters. Results: Lymphocyte, neutrophil, platelet, SII, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio were compared between the groups. No significant differences were observed. There was no significant difference in terms of the SII and other parameters in the H. pylori (+) group when the “1(+)” and “2(+) and 3(+)” subgroups were compared. No significant relationship was found between tissue activity and chronicity score values and inflammatory markers. Conclusion: No correlation was found between the presence and severity of H. pylori and the SII. This is the first study to compare inflammatory markers in the blood with activity and chronicity findings in the tissue.
Molecular ınsights into the diversification and biogeographic history of six astragalus l. sections in the Turkish flora
(Multidisciplinary Digital Publishing Institute (MDPI), 2025) Ateş, Mevlüde Alev; Karaman, Seher; Aytaç, Zeki
With 493 taxa and 63 sections, Astragalus L. is the largest genus in Türkiye. Most of these are narrow endemics and usually found in marginal habitats or require edaphic specializations (about 42% of the species are endemic). Due to the genus’s extensive diversity of species and common economic use, numerous scientific studies have concentrated on specific species. Taxonomic categorization based on morphological characteristics is insufficient to distinguish certain taxonomic groups. However, there is no systematic molecular phylogenetic analysis of Turkish species that deals with speciation in this genus. To concentrate on molecular-level speciation, fresh leaves from 152 samples representing 30 species across six sections native to Türkiye were collected over several months of comprehensive field studies and analyzed with regard to the internal transcribed spacer (ITS) of nrDNA and the trn L5′-L3′ + L3′-F(GAA) + mat K of cpDNA regions. Additionally, molecular clock estimations and biogeographical histories were analyzed to clearly understand the species’ divergence. Based on all studied regions, the Poterion section was found to be the newest and most divergent section, while the Megalocystis Bunge and Halicacabus Bunge sections were the closest and older ones. Furthermore, A. vaginans from section Hymenocoleus Bunge were included not only in this section but also in several other lineages. It is noteworthy that A. dipodurus and A. oleaefolius species from the section Macrophyllium Bunge are usually put together in a distinct sub-branch from other species members of the section in phylogenetic trees generated using both researched cpDNA and nrDNA regions. Moreover, some of the species are divided by the Anatolian diagonal, and the speciation of a significant number of species began during the Pleistocene geological time period. Geographical isolations or other weak isolation mechanisms preceded speciation in Astragalus, which requires more research in the future.
