    ACCESSIBILITY AND ATTRACTIVENESS OF PRIMARY CARE SERVICES IN ALGERIA
    (Oum-El-Bouaghi University, 2017) Aissaoui, Nasreddine; Brika, Said
    The restructuring of basic health care structures represented by public institutions nearby care in Algeria, according to Executive Decree 07/140 of 19 May 2007, could have effects both positive and negative: positive effects as we quote the approximation of diversified health services towards the citizen. As for the negative effects they live in ignorance of the real role of this kind of structure, namely the prevention in the broad sense of the term before the one of care. Among the results of our case study on the 7 wilayas of eastern Algeria, we noted: a small financial allocation and a shortage of medical and paramedical human resources, which have frozen the role of these NHPF, and which have favored the caregiver’s recourse to hospital emergencies. On the other hand, we have also noticed the sufficient number of these structures throughout all the communes of the country and their proximity to the living environments, despite the derisory number of services rendered, which were able to meet certain needs of the inhabitants.

    Libéralisation du marché gazier de l'Union européenne
    (Université d' Oum El Bouaghi, 2016) Ati, Lamia; Brika, Said
    L'organisation traditionnelle de l'industrie gazière européenne dominée par des monopoles intégrés, et des contrats de long-terme, est de plus en plus critiquée. L'Union Européenne s'est donc engagée dans une démarche de libéralisation de son marché en espérant la création d'un marché unique, de pallier aux effets du protectionnisme, d' assurer la sécurité d'approvisionnement, et de faire accroître l'efficacité. L'objet de cette thèse est de mettre en évidence la démarche de libéralisation d'une industrie de réseau, tel est le cas de l'industrie gazière de l'Union Européenne, ainsi de déterminer ses conséquences en termes de : structure du marché, de comportement stratégique des opérateurs gaziers, de performance contractuelle. Une application au cas de l'Algérie, en tant que fournisseur gazier, fait l'objet de la dernière partie de cette thèse, elle nous a révélé : 1-un changement du comportement stratégique de la compagnie nationale SONATRACH avec l'adoption d'une intégration en aval sur le marché gazier européen, mais qui reste encore modeste,2- des modifications sur le fond et la forme contractuelle

    What is the true meaning behind the stochastic hypothesis which assert that E(ε)=0 ?
    (Oum-El-Bouaghi University, 2017) Djeddi, Tarek; Brika, Said
    The aim of this Paper is to examine the meaning about the classical hypothesis which claim that the error of expectation equal zero, by mentioning all theories of expectations before and after the REH. The rational expectations paradigm has dominated the field of economics ever since it was introduced some fifty years ago. Recently research in heterogeneous expectations, bounded rationality, and models of learning have gained leverage, and focus has shifted away from the rational expectations hypothesis. Despite these developments over the past few decades, the rational expectations paradigm is still very much the standard way of handling uncertainty in economic theory, and often the rationality assumption is not seriously questioned.
