Integrating technology into English language teaching at Indonesian high schools: Teachers’ reflections
(Universitas Syiah Kuala, 2025-05) Anwar, Choiril; Hartono, Hartono; Yavuz, Fatih; 131069
English Language Teaching (ELT) is something that has changed dramatically in recent times due to technology. Even though it could potentially reshape ELT, appropriate implementation remains a challenge for most teachers who are often uncertain as to how to use technology to improve learning. This article looks into the experiences and reflections of Indonesian high school English teachers integrating technology into their ELT pedagogical practices, from making lesson plans, having classroom activities, to setting up the assessment. Quantitative and qualitative data were collected and analyzed through a mixed-methods approach. It involved an online survey distributed to 20 diverse Indonesian high school English teachers as well as semi-structured interviews conducted with 10 teachers. The results indicated that there is an increasing use of technology for ELT purposes, particularly to facilitate language reception, language production, and interaction. The results also found some challenges and limitations, including technical issues, training and support, and access equity. These insights can help guide the future development of Indonesian high school ELT practices, inform investment in technology infrastructure, and support targeted professional development initiatives focused on technology integration. The findings are discussed in the context of existing research on ELT and technology integration, with particular emphasis on their significance for high school English teachers in Indonesia. The results provide implications for ELT policymakers, practitioners, and researchers in Indonesia and evidence the importance of context-sensitive solutions to provide meaningful integration of technology in the variability of Indonesian high school settings.

Development of Diallyl Phthalate-Filled Ceramic Shell Self-Healing Capsules for High-Temperature Polymer Composites
(MDPI, 2025-06) Yazıcı, Murat; Karaman, Aycan; Şahin, Eslem; Duran, Gönenç; 414011; 370010
In this study, a production method for ceramic shell macrocapsules and a high-temperature-resistant, polymer agent-based self-healing system was developed. Two types of macrocapsules were created by filling hollow ceramic capsules with high-temperature-resistant diallyl phthalate (DAP) resin, known for its thermal stability, and a peroxide-based curing agent. These capsules were incorporated into epoxy and DAP matrix materials to develop polymer composite materials with self-healing properties The macrocapsules were produced by coating polystyrene (PS) sacrificial foam beads with raw ceramic slurry, followed by sintering to convert the liquid phase into a solid ceramic shell. Moreover, FTIR, TGA/DTA, and DSC analyses were performed. According to the thermal analysis results, DAP resin can effectively function as a healing agent up to approximately 340 °C. In addition, quasi-static compression tests were applied to composite specimens. After the first cycle, up to 69% healing efficiency was obtained in the epoxy matrix composite and 63.5% in the DAP matrix composite. Upon reloading, the second-cycle performance measurements showed healing efficiencies of 56% for the DAP matrix composite and 58% for the epoxy matrix composite.

Development of Self-Healing Thermoplastic Composites With Reactive Thermoplastic Agent-Filled Macrocapsules
(Wiley, 2025-05) Şahin, Eslem; Boztoprak, Yalçın; Yazıcı, Murat; 414011
Self-healing materials, which introduce a new approach to innovative materials, can aid in the repair of polymers and composites, leading to the development of more durable and reliable products. In polymer matrix composites, healing micro- or macrocracks helps to eliminate structural defects. A reactive healing agent and curing agent distributed within the thermoplastic matrix can react at the crack site, providing repair without external intervention. Acrylic resin and polypropylene were selected for this study to evaluate the potential of healing in industrial thermoplastics. Capsules filled with a reactive agent containing 3% by weight diethylenetriamine (DETA) were embedded in the matrix. When damaged, these capsules broke, and the liquid agents seeped into the cracks through the filling voids. The reaction released immediate heat, initiated curing, and filled the damaged area. Complete curing occurred after 8 h. The energy absorption of specimens in both damaged and undamaged states was observed through compression testing. The heat generated by the agents flowing from the capsules during the compression test was monitored using a thermal camera. This study offers a new perspective on using reactive thermoplastic resins to develop self-healing composite materials.

Economic growth and fisheries biocapacity in BRICS+T: An Environmental Kuznets Curve analysis
(Ege University, 2025-03) Canbay, Şerif; Şengül, Serkan; 278780; 355807
This study evaluates the robustness of the Environmental Kuznets Curve (EKC) hypothesis by examining the association between economic growth and fisheries biocapacity in BRICS+T countries, namely Brazil, Russia, India, China, South Africa, and Türkiye. Panel bootstrap causality test is utilized to evaluate the causal relationship between the variables using data covering the period 1992-2022. The results show that the EKC hypothesis is held for Russia, South Africa and Türkiye and that economic growth initially causes to a decrease in fisheries biocapacity, but after a certain threshold, biocapacity recovers. In contrast, the EKC hypothesis is not supported for Brazil, China and India. These findings necessitate governments to take policy measures to promote environmental sustainability.

Hungarian Foreign Policy towards the Turkic States: A Motivation for a More Authoritarian‑Leaning Political Model or a Pragmatic Will for Economic Gain?
(Metropolitan University Prague Press, 2025-04) Hasan, Barış; Topuz, Ali Kılıçarslan; 416023
This study examines the relationship between the recent discussions that Hungary has moved away from fundamental democratic values and turned into an illiberal democracy and the transformation of Hungarian foreign policy by taking Hungary’s relations with the Turkic states as a case. The dynamics of Hungarian foreign policy towards the Turkic states as part of Hungary’s post-2010 strategy of Eastern Opening are taken as a case study and the influences of these dynamics on perception differences about Hungarian democracy are analysed. It is discussed whether Hungary’s developing political and economic relations with the Turkic states since 2010 involve an emulation of the political models of these states and whether this has an impact on the so-called transformation of Hungarian democracy into an illiberal democracy. It attempts to reveal the extent to which foreign policy developments are decisive for Hungarian domestic politics and, in particular, to identify the triggering factors for Hungary’s rapprochement with the Turkic states. It seeks to answer the question of whether Hungary’s motivation to adapt a more authoritarian -leaning political model or pragmatic economic intentions are more hegemonic in the relationship between Hungary and the Turkic states.
