skills mismatch and inadequacy education-job -analytical study of previous studies-
No full textThe emergence of the theory of human capital in the late sixties of the last century in the United States of America contributed to the expansion of higher education, but the results of this were the emergence of a defect in the labor market represented in the imbalance of the relationship with work education, which took different forms, and the continuation of the phenomenon for a long time contributed to the spread of unemployment. Through our research paper, we will address the topic of the imbalance of the education-work relationship within a theoretical context, in an attempt to identify what it is as one of the new topics that fall within the economics of labor, which is concerned with determining the productivity of individuals, and we have relied on the descriptive analytical approach of previous studies that have already dealt with the subject from different perspectives.

La production de l’énergie électrique dans les zones isolées Le cas du Grand Sud de l’Algérie: Electric power generation in the isolated areas The case of Great South of Algeria
Get PDFThe purpose of this study is to verify the economic profitability of a broad integration of renewableenergies in the electricity production sites of the South Isolated Grids of Algeria. Production ensured bydiesel engines and small power gas turbine units. Unable to be connected to the national interconnectedgrid, the coverage of the local demand for electricity in these regions is very expensive and increasesdramatically with distance and isolation.Guaranteeing an energy mix is an objective imposed on Algeria to make conventional power plantsprofitable and reduce fuel consumption. The hybridization of diesel plants with photovoltaic solarpower plants contributed to reducing the consumption of fossil fuels and to ensure an intergenerationalsaving of resources.L’objectif de cette étude est de vérifier la rentabilité économique d’une intégration des énergiesrenouvelables pour la production de l’électricité dans zones isolées des Réseaux du Grand Sud del’Algérie. Une production assurée par des moteurs diesel et des turbines à gaz de petites puissances. Nepouvant pas être raccordés au réseau interconnecté national, la couverture de la demande locale del’électricité de ces régions est très coûteuse et augmente radicalement avec les distances et l’isolement.Garantir un mix-énergétique est un objectif imposé à l’Algérie rentabiliser les centralesconventionnelles et réduire la consommation du combustible. L’hybridation des centrales diesel par descentrales solaires photovoltaïques contribue à la réduction de la consommation des combustiblesfossiles et d’assurer une économie de ressources intergénérationnelle
