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

The control sample showed increased in bacterial logarithmic for total count bacterial, coliform, Staphylococcus aureus, proteolytic bacteria, lipolytic bacteria and mold and yeasts during of storage period , the highest results showed at the latest storage period 14days, it w
The problem of multi assembly line balancing appears as one of the most prominent and complex type of problem. The research problem of this dissertation is concerned with choosing the suitable method that includes the nature of the processes of the multi assembly type of the sewing line at factory no. (7). The State Company for Leather Manufacturing. The sewing line currently suffers from idle times at work stations which resulted in low production levels that do not meet the production plans. The authors have devised a flexible simulation model which uses the uniform distribution to generate task time for each shoe type produced by the factory. The simulation of the multi assembly line was based on assigni

... Show MoreThe growth curves of the children are the most commonly used tools to assess the general welfare of society. Particularity child being one of the pillars to develop society; through these tools, we can path a child's growth physiology. The Centile line is of the important tools to build these curves, which give an accurate interpretation of the information society, also respond with illustration variable age. To build standard growth curves for BMI, we use BMI as an index. LMSP method used for finding the Centile line which depends on four curves represents Median, Coefficient of Variation, Skews, and Kurtosis. These can be obtained by modeling four parameters as nonparametric Smoothing functions for the illustration variable. Ma

... Show MoreIn the pandemic era of COVID19, software engineering and artificial intelligence tools played a major role in monitoring, managing, and predicting the spread of the virus. According to reports released by the World Health Organization, all attempts to prevent any form of infection are highly recommended among people. One side of avoiding infection is requiring people to wear face masks. The problem is that some people do not incline to wear a face mask, and guiding them manually by police is not easy especially in a large or public area to avoid this infection. The purpose of this paper is to construct a software tool called Face Mask Detection (FMD) to detect any face that does not wear a mask in a specific
... Show MorePollutants generation is strongly dependant on the firing temperature and reaction rates of the gaseous reactants in the gas turbine combustion chamber. An experimental study is conducted on a two-shaft T200D micro-gas turbine engine in order to evaluate the impact of injecting ethanol directly into the compressor inlet air on the exhaust emissions. The study is carried out in constant speed and constant load engine tests. Generally, the results showed that when ethanol was added in a concentration of 20% by volume of fuel flow; NOx emission was reduced by the half, while CO and UHC emissions were almost doubled with respect to their levels when burning conventional LPG fuel alone.
