: This study investigated the impact of audio-visual input enhancement teaching techniques on improving English as Foreign Language (EFL) learnersˈ collocation learning as well as their accuracy concerning collocation use in narrative writing. In addition, it compared the impact and efficiency of audio-visual input enhancement in two learning contexts, namely traditional and mobile learning contexts. First, 120 homogenous intermediate EFL learners were randomly divided into four groups, two experimental and two comparison groups. Next, two pre-tests, a collocation and a paragraph writing test, were administered. The experimental groups received enhanced target collocations through input enhancement teaching techniques while in the comparison groups the “unenhanced” collocations were taught through conventional simple vocabulary teaching method. After the treatment sessions, the researcher administered two post-tests including a collocation and a paragraph writing. As the data analysis suggested, with regards to the first research purpose, audio-visual input enhancement positively affected EFL learners' collocation learning and enhanced their accuracy concerning collocation use in narrative writing. Regarding the second purpose of the study, the results revealed that, in comparison to traditional learning context, audio-visual input enhancement teaching techniques were significantly effective in mobile learning context in terms of collocation learning. The efficiency of audio-visual input enhancement teaching techniques was not significantly different between the experimental groups in the two learning contexts in terms of enhancing EFL learners’ accuracy concerning collocation use. The findings of this study can create awareness for second language teachers and learners about the critical and beneficial role of input enhancement and mobile assisted language learning in successful language acquisition and learning.

The complexity of self-regulatory strategies has been challenging to educational researchers who seek to find proper interventions that benefit students and teachers. This study has employed the Self-Regulatory Strategy Development (SRSD) model of instruction to help students monitor, evaluate and revise their writing. SRSD would be beneficial for adult students with learning disabilities in the procedure of essay writing. Attention Deficit Hyperactivity Disorder (ADHD) as a cognitive-behavioral dysregulation is a consequence of deficits in self-regulatory process. Many students with learning disorders such as ADHD have trouble in the mechanics and process of writing. The purpose of this study is to explore the effects of SRSD on the essay writing of EFL undergraduate students. This study tried to evaluate the effects of SRSD intervention on the essay writing of ADHD and NON-ADHD students. To fulfill the mentioned objectives, 126 EFL undergraduate students who enrolled in essay writing course at Tehran Azad University participated in this study. The results indicated that SRSD instruction had a significant effect on the essay writing of the EFL undergraduate students. Likewise, ADHD students could achieve a significant improvement after receiving SRSD intervention. چکیده: پیچیدگی روش های خود تنظیمی برای محققین حوزه آموزش معمولا چالش برانگیز بوده است و آنها همیشه سعی در یافتن روش مناسبی برای دانشجویان و اساتید در این زمینه داشته اند. این تحقیق از روش "استراتژی های ایجاد خود تنظیمی" برای کمک به دانشجویان در زمینه های مشاهده، ارزیابی و تجدیدنظر بهره برده است. "استراتژی های ایجاد خود تنظیمی" برای دانشجویانی که در زمینه نگارش مشکل دارند مفید خواهد بود. "اختلال بیش فعالی کمبود توجه" به عنوان یک نابهنجاری شناختی- رفتاری، که درنتیجه اختلال درفرایند خود تنظیمی بوجود می آید، مورد بررسی قرار گرفت. بسیاری از دانشجویان که در یادگیری دچار مشکل هستند برای مثال آنهایی که "اختلال بیش فعالی کمبود توجه" دارند در روند و مراحل مقاله نویس با مشکلاتی روبرو هستند. هدف این تحقیق بررسی تاثیرات "استراتژی های ایجاد خود تنظیمی" بر توانایی نگارش دانشجویان کارشناسی زبان انگلیسی (زبان انگلیسی به عنوان زبان بیگانه) بوده است. این تحقیق به منظور ارزیابی تاثیرات بکارگیری روش "استراتژی های ایجاد خود تنظیمی" بر نگارش دانشجویانی که مشکل "اختلال بیش فعالی کمبود توجه" داشتند و دانشجویانی که این مشکل را نداشتند انجام شد. به این منظور 126 دانشجوی کارشناسی زبان انگلیسی (زبان انگلیسی به عنوان زبان بیگانه) که درس مقاله نویسی را در دانشگاه آزاد اسلامی میگذراندند در این تحقیق شرکت کردند. نتایج نشان داد که روش آموزشی "استراتژی های ایجاد خود تنظیمی" بر توانایی مقاله نویسی دانشجویان تاثیر قابل توجهی داشت. همچنین دانشجویانی که مشکل "اختلال بیش فعالی کمبود توجه" را داشتند بعد از بکارگیری "استراتژی های ایجاد خود تنظیمی" پیشرفت قابل ملاحظه ای داشتند.  کلید واژه ها: اختلال بیش فعالی کمبود توجه – خود تنظیمی – استراتژی های ایجاد خود تنظیمی – مقاله نویسی.  

The purpose of this study was to design and formulate strategic liquidity management strategies in the banking industry. In this research, in order to combine qualitative and quantitative data, a sequential integrated exploratory method will be used, according to the classification model with emphasis on qualitative data. Therefore, according to its objectives, the present study is part of applied research and in terms of the research process is part of descriptive and exploratory research that was conducted in two parts: qualitative and quantitative. The statistical population of the present study was the qualitative part of the managers of the Welfare Bank. The sampling method was to achieve theoretical saturation and 25 people were selected as the sample size. Therefore, a survey was used to collect information and according to the data collection, two types of tools were used to review documents, interviews, and questionnaires, and the evaluation method of the questionnaire was performed with a 5-point Likert scale. The Cronbach's alpha questionnaire was used. SWOT analysis was used to analyze the data. The results showed that the Welfare Bank has many opportunities to develop appropriate liquidity management strategies. As it was observed, the chart stretches towards the opportunities and strengths of the offensive situation, which requires strategic planning to use the strengths and opportunities, and 11 strategies were developed for this purpose.

The phenomena of fatigue of voluntary muscular effort is intricate and multidimensional in the field of sports sciences. The causes and effects of exercise-induced fatigue have been extensively studied, but the central nervous system's (CNS) involvement in this process is still unclear. In order to understand CNS fatigue after physical activity, the current review will examine changes in neurotransmitter function during exercise. Using primary sources such scientific journals and websites, a consensus and critical evaluation were carried out in order to accomplish this goal. For a number of neurotransmitters, including dopamine and serotonin (5-HT; 5-hydroxytryptamine), hypotheses have been established. The most well-known one is a rise in serotonin levels throughout the brain. Nutritional interventions intended to reduce brain serotonin synthesis during extended exercise enhance endurance performance, and there is strong evidence that increases and decreases in brain serotonin activity during prolonged exercise, respectively, accelerate and delay fatigue. There are several physiologically connected causes of fatigue. It is important to better understand how CNS effects affect fatigue in order to achieve maximum muscle performance in both daily life and athletics.
