تهدف الدراسة الحالية الى استعمال الانموذج اللوجستي ثنائي المعلم في تدريج مقياس الشخصية الافتراضية المتعدد الابعاد لطلبة الجامعة وفقا لنظرية الاستجابة للفقرة، والخروج بتعميم لنتائج البحث والوقوف على الاجراءات العلمية المناسبة وتوفير تطبيق عملي علمي صحيح لاعتمادها من قبل الباحثين. وقد اتبعث الباحثة الاسلوب العلمي من خطوات واجراءات في عملية بناء المقياس حيث حدت ابعاد الشخصية الافتراضية المتمثلة بسبع ابعاد هي (النفسية- الاجتماعية - الثقافية - السياسية - الدينية - العاطفية - الترويحية) ، وقد عرض المقياس بابعاده السبعة وفقراته الى المحكمين المتخصصين في العلوم التربوية والنفسية،وتم الاتفاق بين الخبراء حول صلاحية الفقرات الظاهرية واعتماد المساواة في عدد الفقرات لكل بعد من الابعاد بين اتفاق المحكمين. واصبح المقياس بعد اتفاق الخبراء بمعدل (13) فقرة لكل بعد من الابعاد السبعة وباسلوب العبارات التقريرية مع خمس بدائل للاجابة ، ليصبح المقياس متكون من (91) فقرة اختبارية، وبعد اجراءت التطبيق الاولي اصبح المقياس صالح للتطبيق، وتم تطبيق المقياس على عينة بلغت (915) طالبا وطالبة من جامعات العراق.وتم التحليل الاحصائي لفقرات المقياس باستعمال البرامج الاحصائية ال ( STATA ) لكل بعد من الابعاد السبعة وبعد استخراج معاملات الصعوبة للعتبات الخمسة لكل فقرة من فقرات المقياس حيث تم استبعاد (16) فقرة من جميع الابعاد كانت القيمة الزائية المحسوبة لها اقل من القيمة الجدولية ثم اعيد التحليل الاحصائي لابعاد الشخصية الافتراضية بفقراته ال (75) حيث تراوحت معامل الصعوبة لكل بعد وعلى التوالي بين (-2.590الى2.116) ، (-2.256الى1.677) ، (-.089،1الى1.251) ، (0.762الى 2.05)، (-2.105الى0.719) ، (-2.163الى0.821) ، (-0.811الى1.016). في حين تراوحت معاملات التمييز وعلى التوالي (0.362الى 0.739) ، (0.289 الى 0.841) ، (0.494 الى 0.968) ، (0.381 الى 0.976) ، (0.185 الى 0.628) ، (0.264 الى 0.901) ، (0.399 الى 0.720) في حين تراوح الخطأ المعياري للابعاد السبعة وعلى التوالي (50.23 الى 51.59) ، ( 50.18 الى51.96) ، (50.17 الى 50.96) ، (50.22 الى51.21) ، (50.11الى 51.19) ، (50.46 الى 51.45) ، (50.26 الى 51.14 ) كما تم استخراج تقدير القدرة المقابلة للدرجة الخام والخطأ المعياري لها ودالة معلوماتها والاحتمالية حيث كان الخطأ المعياري عند درجة خام (98) عالي وعند الدرجة الخام (371) عالي ايضا وهذا يعود الى الى القدرة المتطرفة عند هذا المستوى ضعيف جدا ويرتفع عند الوسط . كما يلاحظ ان دالة المعلومات كانت منخفضة عند الاطراف وتحسنت عند الوسط وبلغت اقصى قيمة لدالة المعلومات ( 32.79909) عند الدرجة الخام (287) كما تعكس دالة المعلومات ثبات الفقرة مما يشير الى مناسبة الاختبار للطلاب وقادر على التمييز فيما بينهم. كما تبين ان العتبات متدرجة في الصعوبة، وتكاد تكون متساوية في التمييز ، والتخمين هنا ليس له أي تأثير واضح. وبذلك قد تحققت الباحثة من جميع افتراضات نظرية استجابة الفقرة . كما تم التحقق من دلالات الصدق والثبات لمقياس الشخصية الافتراضية

As the template using Cefalexin (CFX), 1-vinyl imidazole (VIZ) and vinyl acetate (VA) as monomer, and N, N-methylene bis acrylamide (MBAA) as cross-linkers and benzoyl peroxide as the initiator, two MIPs were prepared. The same composition was used in non-impressed polymers (NIPs) preparation, but without the template (Cefalexin). For the membranes preparation, numerous plasticizers, such as tri-oly phosphate (TOP) and di-octyl phthalate (DOP), were used in the PVC matrix, slop, detection limit, lifetime, and linearity range of CFX-MIPs electrodes are characteristics &nb
