أشارت الجهود المعرفية السابقة إلى وجود اهتمام متزايد بالجماعات (Groups) على أساس أنها اللبنات الأساسية لقيام المنظمات. وقد فرض تعدد المنظمات في المجتمعات المعاصرة وتباينها من حيث أهدافها وطبيعة نشاطها، تجزئة فعالياتها إلى تخصصات عدة على وفق إطار تقسيم العمل، وبما أدى إلى تقسيم الأفراد العاملين إلى جماعات مختلفة في أدائها وأحجامها وشكلها، والتي تعمل جميعها لتحقيق هدف تلك المنظمات الذي قامت من اجله، مما يحقق لها البقاء والتقدم في وسط بيئة تتصف بالتغيير السريع. ولعل ابرز ما يشغل الباحثين والممارسين والدارسين للجماعات، هو تحقيق التناسق والتكامل داخلها، ومن أبرز أشكال التناسق والتناغم بين أفراد الجماعة الواحدة هو التعاون (Cooperation) ولقد عدَ (Barnard 1938) وهو أحد أوائل المنظرين في مجال التنظيم الحديث، التعاون شيئاً مهماً جداً لبقاء الوحدة الاجتماعية مستمرة في تلك الوحدة التي يرفع أعضاؤها بعضهم البعض للسلوك التعاوني. وهنالك منظرون آخرون تأثروا بـ Barnard)) أمثال (March & Simon)و (Thomson)، أدخلوا فيما بعد آراء مماثلة لارائه، وبالنتيجة صار التعاون مفهوماً أساسياًً في علم المنظمة والسلوك التنظيمي (Wagner, 1995). وعلى الرغم من الأهمية الكبيرة للتعاون، إلا أن المرء ينظر من خارج علم المنظمة ليجد سيلاً كبيراً من النظريات والبحوث والدراسات التي تتعلق بالتعاون بين أنواع الجماعات في منظمات الأعمال المعاصرة. فقد قام الباحثون في مجال الاقتصاد، وعلم النفس الاجتماعي بدراسة الأنماط السلوكية التي سميت "بالتطفل"Free–Riding) ) "والتواكل" Loafing Social)) أو الاعتمادية على الغير (Wagner, 1995)، وسعت بدورها إلى تحديد العوامل التي تعيق ميول الأفراد نحو التعاون. وفي مجال آخر من البحوث علقّ عدد من علماء الاجتماع على الميول الفردية للعديد من النظريات الحالية بشأن التعاون الاجتماعي والسلوك الإنساني، وأتجه بعضهم للقول إلى أن وجود الميول المتجهة نحو الجماعية قد تحفز التعاون بطرائق لم يجرِ تصورها في معظم البحوث، ومن هذا المنطلق، يجد الباحثان أنفسهما أمام أهمية دراسة مدخل الجماعية وأثره في تعاون الأفراد والجماعات داخل المنظمات، ومن أبرز ما وجداه مهماً هو هذا المدخل الذي يقود الفرد العامل في جماعة ما إلى تحديد سلوكياته داخلها، ومن ثم فأن اتجاهاته تؤثر في سلوكياته نحو التعاون مع أقرانه في الجماعة، أو عدم التعاون معهم.
Multilevel models are among the most important models widely used in the application and analysis of data that are characterized by the fact that observations take a hierarchical form, In our research we examined the multilevel logistic regression model (intercept random and slope random model) , here the importance of the research highlights that the usual regression models calculate the total variance of the model and its inability to read variance and variations between levels ,however in the case of multi-level regression models, the calculation of the total variance is inaccurate and therefore these models calculate the variations for each level of the model, Where the research aims to estimate the parameters of this m

In order to achieve these objectives, they have certain means of law (search, arrest, use of force that may be lethal in some cases). However, such means may be misused in a way that harms members of society such as (Exceeding the Scope of a search warrant, violation of privacy of individuals, False Imprisonment, Excessive use of force, Sudden Deaths in custody, Sexual Assault and Harassment, Failure to respond for Domestic violence calls), which raises the civil liability of police officers and their agencies for such damage. Police officers may even abuse their characteristics even outside offic

The problem stems from knowing the impact of the merger on the profitability ratios of the companies. The research field was represented by the companies affiliated to the Ministry of Industry and Minerals (21) companies, while the research sample reached (6) companies after the merger (14) companies before the merger, was based on data The f

Show MoreThis study is concerned with the comparison of the results of some tests of passing and dribbling of the basketball of tow different years between teams of chosen young players in Baghdad. Calculative methods were used namely (Arithmetic mean, Value digression and T.test for incompatible specimens). After careful calculative treatments, it has been that there were abstract or no abstract differences in the find results of chestpass, highdribble and cross-over dribble. The clubs were: (Al-Khark, Air defence, Police and Al-Adamiyah) each one separate from the other for the year (2000-2001). After all that many findings were reached such as the lack of objective valuation (periodical tests) between one sport season and the other. In the light

Show MoreIn this study, ultraviolet (UV), ozone techniques with hydrogen peroxide oxidant were used to treat the wastewater which is produced from South Baghdad Power Station using lab-scale system. From UV-H2O2 experiments, it was shown that the optimum exposure time was 80 min. At this time, the highest removal percentages of oil, COD, and TOC were 84.69 %, 56.33 % and 50 % respectively. Effect of pH on the contaminants removing was studied in the range of (2-12). The best oil, COD, and TOC removal percentages (69.38 %, 70 % and 52 %) using H2O2/UV were at pH=12. H2O2/ozone experiments exhibited better performance compared to

The current study aims to determine the prevalence of Trichomonas vaginalis and Candida spp., and also to identify Candida parapsilosis and some virulence genes. It was conducted in Bint Al-Hoda Hospital of Maternity and Children in Thi-Qar province, south of Iraq for the period from the beginning of January to the end of December 2020. Two hundred and fifty samples were collected from the female genital tract for women whose age ranged between 17-50 years. Microscopic, traditional and molecular tests were used in the sample examination. The results recorded 12 (4.8%) samples infected with T. vaginalis parasite, whereas 130 (52%) samples showed Candida yeast distributed as follows: 75 (30 %) <

Objective of this research focused on testing the impact of internal corporate governance instruments in the management of working capital and the reflection of each of them on the Firm performance. For this purpose, four main hypotheses was formulated, the first, pointed out its results to a significant effect for each of corporate major shareholders ownership and Board of Directors size on the net working capital and their association with a positive relation. The second, explained a significant effect of net working capital on the economic value added, and their link inverse relationship, while the third, explored a significant effect for each of the corporate major shareholders ownershi
