تعتبر المدرسة المتوسطة هي القاعدة التعليمية الثانية بعد المدرسة الابتدائية والتي تقوم عليها أنظمة التعليم المتنوعة فهي تمثل اللبنة الثانية في الصرح التعليمي لأنها مرحلة مهمة تستقبلها الطلبة في العمر الحرج المليء بالتطورات الجديدة على المستويات الثلاثة البايلوجي والنفسي والاجتماعي وعليه يأتي هنا دور القيادة التربوية للقيام بواجباتهم الإدارية والقيادية في قمة الهرم الإداري للمدرسة المتوسطة والتي تستوجب بلا شك امتلاكهم القدرات والمهارات اللازمة لقيادة العمل التربوي.
لذا يعد مدير المدرسة المتوسطة قائد تربوي له الدور المهم والفاعل في نجاح العملية التربوية في المدرسة التي يتولى أدارتها ويفترض أن تكون لديه الخبرة والمؤهلات اللازمة ولولا التنظيمي والالتزام من خلال قيادة مدرسة ناجحة تعمل على إرساء علاقات إيجابية مع المدرسين ويثر حوافزهم لعمل ويرى الباحث أن مديري المدارس المتوسطة لا يسيروا في قيادة مدارسهم وتعاملهم مع المدرسين والطلبة وأفراد المجتمع المحلي الذي لهم اتصالات أو علاقات مختلفة مع المدرسة على نمط واحد في القيادة ولا يكون لديهم برامج يطبق في المدرسة أو تنفيذ في تعاملهم الشخصي واجراتهم ووسائلهم الإدارية باختلاف حلقاتهم الإدارية من جهة واختلاف أعدادهم وتدريبهم واتساع خبرتهم ونظرتهم إلى الإدارة من جهة أخرى، ونظراً لهذا الاختلاف فأننا لا نستطيع أيجاد نمط واحد من أنماط الإدارة أو أسلوب متماثل في سلوك أداري لمدير المدارس المتوسطة كافة، ومع ذلك فان الفاحص أو المدقق لما يجري من هذه المدارس على اختلاف أنواعها ومستوياتها من أعمال أدارية وتصرفات شخصية نستطيع أن نلمس النمط القيادي المتبع من قبل مدير تلك المدارس، أن النمط القيادية الذي يطبق به مدير المدرسة المتوسطة من الممكن أن ينعكس على درجة رضا المدير عن عمله، كما أنه قد ينعكس على سلوكه وإخلاصه وثقافته في صدق أهدافه.
وفي ضوء ما تقدم فان ما يمارسه مديرو المدارس من أنما قيادية وعلاقتها برضا العاملين في المدارس المتوسطة من أعضاء الهيئات التدريسية أو المشرفين الإداريين على وجه التحديد ومدى تأثير هذه الأنماط على مناخ العلاقات الشخصية والإنسانية في هذه المدارس يثير كثير من التساؤلات حول ما يدور داخل هذه المؤسسات التربوية التعليمية والتي يحسها الباحث خلال عمله في الوسط التعليمي وفي هذه المرحلة الدراسية ومعايشته ولقاءاته مع العديد من المشرفين الإداريين وأعضاء الهيئات التدريسية لهذا رأى الباحث ضرورة دراسة هذا الموضوع للتعرف على أنماط القيادات التربوية والإدارية لكتابة عنوان البحث.
This study was conducted to describe a protocol for the callus establishing culture of Lavandula angustifolia plant and estimating their content of volatile oil. The quantity of volatile oil callus tissues was compared with that of leaves production. Callus was induced from leaf explants on Murashige and Skoog medium (MS) supplemented with Naphthalene acetic acid (NAA) and Benzyl adenine (BA) in different concentrations. Maximum callus fresh weight was obtained in the combination of 10 mg/L BA and 3 mg/L NAA which reached 18 g after four weeks. The results of this work showed that the quantity of volatile oil from the highest fresh weight callus was 6 ml compared with quantity of 18g of leaves which gave 0.5 ml. Volatile o

Show MoreThe m-consecutive-k-out-of-n: F linear and circular system consists of n sequentially connected components; the components are ordered on a line or a circle; it fails if there are at least m non-overlapping runs of consecutive-k failed components. This paper proposes the reliability and failure probability functions for both linearly and circularly m-consecutive-k-out-of-n: F systems. More precisely, the failure states of the system components are separated into two collections (the working and the failure collections); where each one is defined as a collection of finite mutual disjoint classes of the system states. Illustrative example is provided.
The electrospun nanofibers membranes have gained considerable interest in water filtration applications. In this work, the fabrication and characterization of the electrospun polyacrylonitrile-based nonwoven nanofibers membrane are reported. Then, the membrane's performance and antifouling properties were evaluated in removing emulsified oil using a cross flow filtration system. The membranes were fabricated with different polyacrylonitrile (PAN) concentrations (8, 11, and 14 wt. %) in N, N-Dimethylformamide (DMF) solvent resulted in various average fiber sizes, porosity, contact angle, permeability, oil rejection, and antifouling properties. Analyses of surface morphology of the fabricated membranes before and after oil removal revealed

Parameters that affect the adsorption experiments were studied and found the optimum pH were 6 and 5 for copper and iron respectively and the time interval was 120 min and the adsorbent mass was 0.1 g. The values for adsorption isotherms parameters were determined according to Langmuir [qmax were 54.64 and 61.7 mg/g while b values were 0.234 and 0.22 mg/l] , Freundlich [Kf were 16.07 and 18.89 mg/g and n were 2.77 and 3.16], Temkin [B were 0.063 and 0.074 j/mol and At were 0.143 and 1.658 l/g] and for Dubinin-Radushkev

The sustainable competitive advantage for organizations is one of the requirements for value creation, which centered on the possession of scarce resources that achieve maximum flows to invest in intellectual capital, if what has been interest in them, measured and employed the way properly and style, so I figured the need for new technologies to enable organizations to measure the intellectual and physical assets and to assess its performance accordingly, so it sheds search light on the measurement of the added value of existing knowledge using the standard value-added factor is the intellectual (value added intellectual coefficient) (VAIC) and to develop a set of assumptions about the extent of the difference between the sample
