This study aimed at evaluating the primary grades’ national education textbooks (4th-6th) from perspective of teachers. The research questions addressed were as follows:1- What was the degree of evaluation of national education textbooks by school teachers in the northern governorates of Palestine?2- Was there a difference in estimates of evaluation of each ofthe five domains according to: sex, academic qualification, experience, type of class and the teaching of the subject for the first time?To answer the research questions, the researcher developed a unified questionnaire for the three textbooks. The questionnaire, in its final version, consisted of 56 items distributed among five domains textbook goals:l3 items; educational aids and activities:l7 items; evaluation:7 items.The population of the study comprised teachers of both sexes involved in the teaching of national education to the three grades in the northern governorates of the West Bank: Jenin, Nablus, Tulkarm, Qalqilya, and Salfit. The total number of the population amounted to 754 teachers of both sexes. The questionnaire was administered on a randomly chosen sample representing 40% of the study population. the number of respondents was 302 teachers during 1998/ 1999 scholastic year. By using arithmetic averages of the degree of evaluation ofthe five domains of the study, the layout of the three textbooks combined occupied the first place. It received a very good evaluation.The arithmetic average was 4.01. The domain of objectives received second place and it had a high evaluation; its arithmetic average was 3,58. The content domain was third in order and its evaluation was also high; its arithmetic average was 3.50. The area of means of evaluation came in the fourth place and its evaluation was on average.Its arithmetic average was 3.37. The educational aids and activities came last and its degree of evaluation was average. The arithmetic average was 3.01. The degree of evaluation of the five domains for the three grades combined was on average. The arithmetic average was 3.49. Pertaining to the teachers’ perspective of the national education curriculum, in terms of its degree of flexibility, it differed depending on sex, qualification, class! grade variable, and variable of the teaching discipline.The T- test has revealed that the males’ evaluations were higher than females in the domain of study. There were differences in the degree of evaluation between veteran and new teachers in favor of the new teachers in the areas of content and educational aids. However, there were no differences in the remaining areas. ANOVA test also revealed that there were differences in the evaluation of flexibility which may be attributed to the qualification in favor of diploma holders. However, no differences were found which may be attributed to grade variable on the domains of the study save the layout domain in favor of the fourth grade.As for teaching experience, the ANOVA test showed differences in the domains of content and educational aids in favor of those having less than five years of experience and those who had more than ten years of experience. But there were no difference among the remaining domains.In the light of the study findings, the researcher came up with the following recommendation. There is a need for more interest and more attractive and effective educational aids so that students can get involved in the material.The content has to be enriched with contemporary social, political, and economic problems in the Palestinian society. Finally, there is a need for further analytical and evaluative studies from different perspectives.

This study is concerned with exploring higher education policy and reforms enacted by three diverse countries, Australia, Canada, and Egypt, to improve the quality of education and its relevancy to job market needs. The purpose of this study is to develop a better understanding of similarities and differences in context and motivations for reform and the subsequent results across the three countries and thus identify the lessons learned. This, in turn, will provide an answer to the prominent question of how can Egypt benefit from the higher education reform journeys undertaken by Australia and Canada. The study employs a “simultaneous comparative analysis,” following Bereday’s four–step method: description, interpretation, juxtaposition, and simultaneous comparison. It takes into account the socio-economic context, historical background, and cultural context of each of the three countries. Next, it explores the main higher education reform initiatives, challenges and results in each country.The main findings explored in this study reveal the urgent need for quality audit procedure to assess each institution’s effectiveness in achieving its goals. It also advocates for assuring and improving the quality of higher education through building self-regulating system. The findings also learn from the Australian experience in providing vocational and technical education, which focused on providing skills for the job market. The study concludes that a quality assurance system is more powerful than accreditation system, as it focuses on student learning outcomes. There is much to learn from policy and practice in Australia to maintain and assure quality. The study recommends conducting consultation with representatives of all stakeholders prior to the development of a new program in reference to the Canadian experiences. Moreover, the role of policy and decision makers must strengthen quality assurance system in the institution internally and from an authoritative agency externally. The study recommends that Egypt prioritizes the completion of accreditation of its all higher education institutions and revisit its admission policy to HE.

La qualité de la nutrition est un facteur clé de tout système d'élevage des ruminants qui se veut efficace (H ARAB et al, 2009). La part importante de l'alimentation des ruminants provient des espèces annuelles spontanées des pâturages naturels, des jachères ainsi que par les résidus des cultures. La question qui se pose: Quelle est la valeur nutritive des espèces spontanées de la plaine du moyen Cheliff ? La présente étude a pour objectifs de déterminer l’inventaire floristique, la composition chimique (MS, MO, Protéines, Minéraux et les fibres (NDF et ADF)) et la digestibilité par deux méthodes (IN VITRO et ENZYMATIQUE) des espèces spontanées de la plaine du moyen Cheliff.

Ce mémoire s’inscrit dans le cadre du projet de recherche intitulé : "Techniquesd’optimisation et d’aide à la décision appliquée aux trains à lévitation magnétiques et a laplanification des systèmes électriques ". Il s’agit de la résolution du problème de larépartition optimale de puissance, en utilisant des nouvelles techniques. Le but de notretravail est la réalisation d’outils de calcul du dispatching économique dans un réseaud’énergie électrique par deux sortes de méthodes à savoir les méthodes déterministes et lesmétaheuristiques. Pour les méthodes déterministes on a dus utilisées la méthode duGradient et Lagrange, pour la méthode métaheuristiques nous avons choisi la méthode desEssaims de Particules.On a commencé notre travail par un calcul de l’écoulement de puissance pourpouvoir évaluer les tensions dans chaque nœud, les puissances générées les puissancestransitées, les puissances injecter aux nœuds et les pertes de transport aux niveaux deslignes de transmission, par la méthodes de Newton Raphson. Nous sommes passée endeuxième lieu à la résolution du dispatching économique par la technique classique dugradient qui est très efficace, exacte mais nécessite de partir d’un point initial proche de lasolution. Elle est basée sur le calcul des dérivées premières qui deviennent pluscompliquées en augmentant le nombre de contraintes avec le risque de convergence versl’optimum local. C’est la raison pour laquelle nous avons pensé à d’autres techniquesglobal plus efficaces. Des recherches ont été développées dans ce contexte, les essaims departicules étaient un de nos multiples choix, cette méthode est très efficace car elle nous apermet la résolution du problème de répartition optimale des puissances, par sa facilité deprogrammation et sa convergence vers l’optimum global .Enfin on estime que ce travail sera un pas dans le développement et l'implantationdes techniques modernes pour résoudre les problèmes liés aux réseaux électriques baséessur les méthodes métaheuristiques et que ce mémoire viendra enrichir la bibliothèque del’université

Today, in the era of Big Data, many organizations around the world realize that the ability to analyze and use big and complex data sets and data streams is becoming one of the most important sources of competitive advantage. Not surprisingly, Big Data capabilities are becoming essential for the survival andsuccess for both private and public organizations. In order for organizations to take full advantage of opportunities that Big Data offers, they need to reach a new level of maturity with respect to data analytics. Some researchers view Big Data as a natural extension of Business Intelligence (BI). Because of that,the current Big Data maturity models are still grounded in the BI era. But the models that have been used for evaluating organizational maturity in relation to BI cnnot be used to evaluate organization maturity in relation to Big Data due to the difference in the underlying processes, methodologies, and technologies. This dissertation highlights the theoretical differnces between BI and Big Data and empirically explores the key Big Data capabilities via a newly proposed Big Data Maturity Model populated by specific Big Datacapabilities at various levels of maturity. The main goal of this research it to develop a practical model that is suitable for evaluating maturity of various organizations in relation to Big Data. The development of the maturity model goes through two main phases. The first iv phase is the literature review phase. The iterature review highlights the limitations of existing maturity models in relation to Big Data and then usesthe Socio-Technical Perspective (STP) and the Resource-Based View (RBV) as its primary theoretical lenses to identify the key capabilities required for working with Big Data. These capabilities fall into the people, technology, and organizational domain. The second phase involves using the developedtheoretical model to empirically explore Big Data capabilities among various organizations. The preliminary results suggest that the Big Data model can be used to discriminate among organizations at various levels of maturity in relation to Big Data. In addition to proposing a preliminary theoretical model for nderstanding what it takes to build Big Data capabilities, this research also provides practical guidance to organizations wishing to improve their Big Data capabilities for the purpose of improving their organizational erformance and gaining competitive advantage over their rivals.
