    The significance of research on students' environmental behavior has grown in response to serious environmental concerns. Nevertheless, there is still a gap in comprehension because sustainable environmental intentions frequently do not manifest as factual behavior. This research aims to explore how sociocultural factors and personal norms affect students' pro-environmental behavior. Additionally, we seek to assess the role of university practices in bridging the gap between intention and actual green behavior. Our primary emphasis is to elucidate how these elements interact to predict pro-environmental behavior across university students, offering insight into effective strategies to prompt environmentally friendly actions and to contribute to cultivating environmentally conscious future generations. We deployed a hypothesis-driven, deductive confirmatory approach, using a quantitative cross-sectional data-gathering technique, based on a random selection of a large sample. 641 responses were collected through an online questionnaire and its hard copy version and validated for analysis. The analysis highlights the significant influence of behavioral intention on pro-environmental behavior. Although the moderation impact of ability, motivation, and opportunity differs, motivation and opportunity are distinguished as key variables that determine the translation of intention into positive and actual environmental conduct. The substantially significant conceptual model's explanatory and predictive power provide useful practical insights for researchers and professionals in anticipating and stimulating pro-environmental behavior. By challenging established assumptions and emphasizing the significance of motivation and personal agency, the current research advances our understanding of university students' pro-environmental behavior. Optimum results could be achieved by integrating personal norms into learning activities, awareness campaigns, and the development of supportive policies. Prospective research might emphasize various demographic categories for a more thorough understanding of the sociocultural effects on pro-environmental behavior. Employing objective measurements may further enhance the accuracy of findings, and longitudinal research has great potential in tracking the evolving dynamics between behavioral intention and pro-environmental behavior, enabling the implementation of highly effective interventions

    تعد أشكال التواصل غير اللفظي جزءا مهما من العملية التعليمية؛ ذلك أنها تساعد المعلم في تحقيق أهداف درسه، وتعين المتعلمين - من الناطقين بغيرها - في اكتساب العربية من جهة أخرى، وفي حال أغفلها المعلمون وخاصة أثناء تدريس المستوى المبتدئ، سيحصل للمتعلمين تشويش مرده إلى انعدام فهم أشكال التواصل المستخدمة، مثل: الإيماءات والإشارات، حيث تكون في ثقافة متعلم ما يختلف مدلولها عن الإيماءة التي يستعملها المعلم وعليه فالمتعلم بحاجة إلى استعمال معلمه للأشكال غير اللفظية؛ وذلك ليكون قادرا على ربط الشكل غير اللفظي - المستخدم من قبل المعلم - بمدلوله اللفظي الذي يعبر عن موضوع الدرس، ومن ثم يكتسب المتعلم العربية، ويصبح قادرا على ممارستها بشكل أفضل مع أقرانه، وهذا جوهر الغاية التعليمية. وفي إطار هذه الإشكالية حاولت الدراسة الإجابة عن سؤال أساس: هل لأشكال التواصل غير اللفظي التعليمية والثقافية ووظائفه أثر في اكتساب متعلمي المستوى المبتدئ للغة العربية؟، ولمعالجة هذا الإشكال اعتمدت الدراسة المنهج الوصفي التحليلي، وقد اختارت الباحثة هذا المنهج؛ لأنه الأنسب لطبيعة الموضوع قيد الدراسة، حيث إنه قائم على ملاحظة المشكلة أو الظاهرة العلمية والشروع في وصفها، ومن ثم جمع البيانات والمعلومات حولها، ونقدها من زاوية تحليلية من أجل وضع نتائج قابلة للتطبيق. ولهذا حاولت الباحثة على مدار هذه الدراسة تناول أثر استخدام المعلمين لأشكال التواصل غير اللفظي ووظائفه في اكتساب متعلمي المستوى المبتدئ العربية وصفا وتحليلا، مع الاستفادة من مجال تعليم العربية للناطقين بغيرها الذي يعد من أبرز مجالات علم اللسانيات التطبيقية. ومن أهم النتائج التي توصلت إليها الدراسة: أن للتواصل غير اللفظي أثرا واضحا في اكتساب المتعلمين للغة العربية، ودليل ذلك أن الأدوات الثلاث التي اعتمدتها الباحثة بينت أن المعلمين يستعملون الأشكال غير اللفظية، مثل: الإيماءة والإشارة، والمصاحبات اللفظية والمسافة التواصلية، والصور التوضيحية التي تنتمي إلى الوسائل والمواد البصرية، لتطويعها في سبيل تقديم المفاهيم الملموسة بصورة يسيرة للمستوى المبتدئ؛ ليصبح المتعلم قادرا على ربط الشكل غير اللفظي بمدلوله اللفظي، ومن ثم يتمكن من اكتساب اللغة العربية.Non-verbal forms of communication play a crucial role in the educational process. They assist teachers in achieving their lesson objectives and aid learners, particularly non-native speakers, in acquiring Arabic. If these forms of communication are overlooked, especially during instruction at the beginner level, learners may become confused due to a lack of understanding of the cultural differences in gestures and references used by the teacher. Therefore, learners need guidance from their teachers to comprehend and connect non-verbal cues with the verbal connotations that express the lesson's content. This enables them to acquire Arabic and improve their ability to practice it with their peers, which is the ultimate educational goal. To address this issue, the study aimed to answer a fundamental question: How does non-verbal communication impact learners' acquisition of Arabic? The research adopted an analytical descriptive approach, which was deemed most suitable for the nature of the topic. This approach involves observing the scientific problem or phenomenon, describing it, collecting data and information, and analyzing it to produce clear results . Throughout the study, the researcher focused on examining the impact of teachers' use of non-verbal communication and its functions in describing and analyzing the acquisition of Arabic by beginner-level students. The study drew on the field of Arabic education for non-native speakers, which is a prominent area within applied linguistics . One of the key findings of the study was that non-verbal communication had a significant influence on learners' acquisition of Arabic. The researcher's analysis, based on three tools, revealed that teachers utilized non-verbal forms such as gestures, references, verbal cues, communication distance, and visual aids to introduce innovative concepts. This enabled learners to associate the nonverbal forms with their verbal meanings and, consequently, acquire Arabi

    The non-invasive fetal electrocardiogram (fECG) enables easy detection of developing heart abnormalities, leading to a significant reduction in infant mortality rate and post-natal complications. Due to the overlapping of maternal and fetal R-peaks, the low amplitude of the fECG, systematic and ambient noises, typical signal extraction methods, such as adaptive filters, independent component analysis, empirical mode decomposition, etc., are unable to produce satisfactory fECG. While some techniques can produce accurate QRS waves, they often ignore other important aspects of the ECG. Utilizing extensive preprocessing and an appropriate framework, our approach, built upon 1D CycleGAN, achieves fECG signal reconstruction from the mECG signal while preserving its morphology. The performance of our solution was evaluated by combining two available datasets from Physionet, “Abdominal and Direct Fetal ECG Database” and “Fetal electrocardiograms, direct and abdominal with reference heartbeat annotations”, where it achieved an average PCC and Spectral-Correlation score of 88.4% and 89.4%, respectively. It detects the fQRS of the signal with accuracy, precision, recall and F1 score of 92.6%, 97.6%, 94.8% and 96.4%, respectively. It can also accurately produce the estimation of fetal heart rate and R-R interval with an error of 0.25% and 0.27%, respectively. The main contribution of our work is that, unlike similar studies, it can retain the morphology of the ECG signal with high fidelity. The accuracy of our solution for fetal heart rate and R-R interval length is comparable to existing state-of-the-art techniques. This makes it a highly effective tool for early diagnosis of fetal heart diseases and regular health checkups of the fetus.This study was funded by Qatar University Grant: QUHI-CENG-22/23-548
