أن كرة السلة بما تتضمنه من مهارات حركية متنوعة تتطلب من ممارسيها امتلاك عدد من القدرات الحركية الخاصة وبشكل خاص التوافق العضلي العصبي والرشاقة والقوة المميزة بالسرعة، فضلاعن قدرات الإدراك الحس- حركي (إدراك المكان وقوة دفع الكرة سواء بالطبطبة العالية أو الواطئة .... الخ ) لذا تكمن أهمية البحث في إيجاد الطرق والوسائل التي تطور قدرة الطالبة على إدراك قوة دفع الكرة والإحساس بها أثناء تعلم وتدريب الطبطبة بأنواعها بإدخال تمرينات إدراك قوة الذراع ومن ثم تأثيرها على مستوى أداء مهارة الطبطبة في كرة السلة . ومن خلال ملاحظة أداء الطالبات في دروس كرة السلة وجدنا ضعف في أداء مهارة الطبطبة سواء كان من الثبات أو من الحركة وعدم إدراك القوة اللازمة لأداء هذه المهارة بصورة صحيحة مما يؤدي إلى ارتباك في الأداء, ويدفع الطالبة إلى إعطاء قوة غير مناسبة وبالتالي ارتفاع الكرة إثناء الطبطبة إلى أعلى من مستوى الحوض أو إعطاء قوة غير كافية مما يؤدي انخفاض مستوى الطبطبة ، وهذا يرجع إلى قلة الإدراك والإحساس بالقوة المناسبة لدفع الكرة ، وهنا تكمن مشكلة البحث. وهدفت الدراسة إلى معرفة تأثير تمرينات إدراك قوة الذراع على مستوى أداء مهارة الطبطبة في كرة السلة . استخدم المنهج التجريبي على طالبات المرحلة الرابعة البالغ عددهم (25) طالبة قسموا على مجموعتين ( تجريبية وضابطة ) طبقت التجريبية تمرينات إدراك قوة الذراع , خلال الطبطبة (دفع الكرة) أدخلت في القسم الرئيسي الجانب التطبيقي من الدرس وبواقع ( 10 ) دقائق وعلى مدى 8 أسابيع . فاستنتج أن لتدريبات إدراك قوة الذراع تأثيراً ايجابياً في تطوير مهارة الطبطبة في كرة السلة لدى إفراد عينة البحث. وتوصي الباحثات بالتركيز على التمارين خاصة بادراك قوة الذراع خلال الدرس للارتقاء بمستوى أداء المهارة .
Abstract
This study aims at investigating the relationship between mindfulness and academic self-efficacy among Northern Border University students. To achieve this objective, the researcher adopted the correlative survey method for (97) students. For data collection, the researcher developed a mindfulness scale consisting of (42) items divided into seven topics, each one consisting of six items. The researcher developed an academic self-efficacy scale consisting of (20) items, adopting a five-point Likert scale. The results showed that there is a high level of mindfulness among students at the level of the seven units which formed the mindfulness scale; the conscious thinking unit showed the highest mean value o

It is caused by mutations in the CTNS gene that encodes the cystine transporter, cystinosin, which leads to lysosomal cystine accumulation. It is the major cause of inherited Fanconi syndrome, and should be suspected in young children with failure to thrive and signs of renal proximal tubular damage. The diagnosis can be missed in infants, because not all signs of renal Fanconi syndrome are present during the first months of life. Elevated white blood cell cystine content is the cornerstone of the diagnosis. Since chitotriosidase (CHIT1 or chitinase-1) is mainly produced by activated macrophages both in normal and inflammator

... Show MoreAbstract: Despite the distinct features of the continuous wave (CW) Terahertz (THz) emitter using photomixing technique, it suffers from the relatively low radiation output power. Therefore, one of effective ways to improve the photomixer emitter performance was using nanodimensions electrodes inside the optical active region of the device. Due to the nanodimension sizes and good electrical conductivity of silver nanowires (Ag-NWs), they have been exploited as THz emitter electrodes. The excited surface plasmon polariton waves (SPPs) on the surface of nanowire enhances the incident excitation signal. Therefore, the photomixer based Ag-NW compared to conventional one significantly exhibits higher THz output signal. In thi

Twitter has become a significant platform for dialogue and interactive discussions. The survey method, specifically the descriptive approach, was employed to answer research questions and achieve objectives. A sample of 100 Iraqi Twitter users was selected, considering demographic variables such as gender, age, and educational background, during the period from September 15 to October 1, 2022.
