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
This study focused on determining the markers of Macrophage migration inhibitor (MIF), as well as the N-telopeptides of type I bone collagen (NTX), and some other parameters (alkaline phosphatase (ALP), vitamin D (Vit D), calcium (Ca), phosphorus (P), and magnesium (Mg), and their correlation with other parameters in osteoporosis. One hundred ten subjects were involved in the current study. There were two groups of patients: group I (30) women with severe osteoporosis and group II (30) women with mild osteoporosis. For comparison, 50 apparently healthy individuals were included as a control. Serum levels of MIF, and NTX were significantly higher in groups I and II as compared to the control group, which indicate that these two parameters

garlic (in the form of segments, chopped or crushed) on the mentioned pickled –food
features . Furthermore, a sense based comparison is made between vinegar-preserved
samples and vinegar-garlic preserved ones.
The following results have been obtained:
1- The isolation of staph. aureus alone from the samples and the study of its physical
and biochemical features.
2- The fresh garlic (segments, chopped and crushed) with concentration of 5%, 7.5%,
and 10% showed a damaging percentage of 100% to bacterial growth of staph. Aureus

Show MoreThe Iraqi and Iranian pottery has a significant role in the contemporary world pottery space, despite the fact that influences created those formulation, thus the researcher supposes that there is a relation between the potter and his environment within Iraq's environment and Iran's environment, which are similar at times and different at other times. The researcher, hence, found himself in front of a number of questions:
1- How much was the Iraqi potter inspired by the environment compared to the Iranian potter?
2- Has the Iraqi and Iranian pottery been really inspired by the environment items or there were modified metaphors?
The current research aims at (identifying the influential environmental characteristics in the Iraq
The study aimed to explore the effectiveness of using rational judgment strategy in teaching science to develop scientific thinking for second-grade students. The researcher utilized the quasi-experimental approach based on (the pre/post designing) of two groups: experimental and control. As for tools: a test of scientific thinking prepared by the researcher that proved its verification of their validity and reliability. The test applied on a random sample of (66) students, divided into two groups: (34) experimental, and (32) control. The results showed that the experimental group outperformed the control group in the post-application of the scientific thinking test, In each skill separately, and in the total skills.
