This study investigates the effect of flipped classroom teaching on foreign language reading anxiety (FLRA) among Algerian first-year EFL students at Nour Bachir University Center, using a sequential explanatory mixed-methods design. Eighty students were divided into flipped or conventional instructional groups. Quantitative data were collected through the Foreign Language Reading Anxiety Scale (FLRAS), Oxford Placement Test (OPT), and measures of motivation and control of cognition. Qualitative data were collected through focus groups, class observation, and learner diaries. Results showed a large reduction in FLRA for the flipped group (Cohen's d = 1.21), with moderation effects of proficiency and motivation. Path analysis revealed that strategic engagement and cognitive control mediated anxiety decrease to some extent. Thematic findings supported these findings and emphasized preparedness, social interaction, and emotional management. The study provides robust empirical support for flipped learning as an affective, anxietyreducing, learner-centered pedagogy in EFL reading classes, with design, pedagogical, and future research implications for affective dimensions of language learning. Reading a second language is cognitively demanding and typically takes place with anxiety when learners are faced with new vocabulary, advanced syntax, and culturally embedded content (Saito, Horwitz, & Garza, 1999). Such anxiety, Foreign Language Reading Anxiety (FLRA), can significantly impede comprehension and erode learners' confidence.
Cet article propose une lecture psychanalytique de Chanson douce de Leïla Slimani, examinant l'irruption de la pulsion de mort dans l'espace domestique. En mobilisant les concepts d'inquiétante étrangeté, de frustration et de clivage, l'étude montre comment l'effondrement du moi de Louise conduit au double infanticide. Ce processus révèle les mécanismes psychiques de la violence ordinaire tout en exposant les failles d'une société marquée par les rapports de domination
This paper proposes a unified framework that leverages biocompatible chitosan substrates and AI-driven optimization to advance terahertz (0.3 THz) Biomedical microstrip patch antennas. Unlike existing approaches that focus solely on electromagnetic performance, this study combines biocompatible material integration with graphene radiators and full SAR validation, hybrid photonic bandgap (PBG3) optimization using evolutionary algorithms (GA, PSO, CMA-ES), and machine learning-based rapid performance prediction. Comparative optimization in CST demonstrated that CMA-ES is the most effective method, achieving a peak gain of 6.11 dBi and 87.4
Wireless communications are rapidly advancing, particularly for smart applications in 5G and 6G networks. Recent research explores biodegradable and environmentally friendly materials for antenna substrates, aiming to balance performance and environmental impact. This study focuses on rectangular microstrip antennas using novel composites based on polymethyl methacrylate with carbon nanotubes (PMMA-CNT) and polybutylene succinate with carbon nanotubes (PBS-CNT) as substrates at 2.4 GHz and 5.8 GHz frequencies. The designed antennas have compact dimensions (PMMA-CNT: 50.68 × 56 × 2 mm3 and 23.8 × 46.5 × 2.2 mm3; PBS-CNT: 41.95 × 50.5 × 2.2 mm3 and 20.2 × 39 × 2.2 mm3). At 2.4 GHz, the PMMA-CNT antenna demonstrates a gain of 4.24 dBi, while PBS-CNT offers 71
The increased needs to improved, precise and efficient diagnostics and monitoring have led to the significant development in healthcare wireless devices. These devices implicate the careful design of a suitable antenna that delivers outstanding performances and satisfies the healthcare standards simultaneously. Besides that, flexibility, mechanical strength and thermal stability must be guaranteed particularly in deformation conditions. Accounting the aforementioned requirements, the antenna’s materials selection is a crucial step. The present paper focuses on investigating a flexible circular meandered loop antenna using PLA/PHBV(Polylactic Acid/Polyhydroxybutyrate-co-hydroxyvalerate)biocompatible blend as a substrate with a dielectric constant of ϵ _r=2.88 ; and SWCNT as a conductor material. The specific fields of interest include the substrate thickness effect, bending situations and Specific Absorption Rate (SAR) analysis. The antenna demonstrates its compactness with a total volume of 0.32 λ _r x 0.32 λ _r x 0.001 λ _r at 2.45 GHz resonant frequency. The proposed antenna achieves a bandwidth of more than100 MHz. Our findings highlight a remarkable realized gain and efficiency values that exceeds 5dBi and 86
