L'intention entrepreneuriale : l'influence des facteurs liés à l'individu et au milieu

L'intention entrepreneuriale est le premier élément nécessaire dans le processus entrepreneurial. Elle reflète la volonté d'une personne de créer une entreprise. Cette volonté est influencée par la personnalité ainsi que les croyances de l'individu sur le milieu environnant. Dans cet article, nous abordons en premier le contexte économique algérien. Ensuite, nous exposons le cadre théorique et conceptuel de notre recherche. Et enfin, nous détaillons une étude quantitative auprès d'un échantillon de la ville de Constantine, en Algérie. Cette étude se propose d'expliquer l'influence des facteurs liés à l'individu et au milieu sur l'intention entrepreneuriale.création d'entreprise; intention; culture; environnement

Comparaison des intentions entrepreneuriales des étudiants : France –Pays arabes

A partir d'une grille de lecture dérivée du modèle psychosocial du comportement planifié d'Ajzen, nous étudions les déterminons des intentions entrepreneuriales affichées par les étudiants en France et dans trois pays arabes, Algérie, Liban et Tunisie. Nous observons que les niveaux mesurés de ces intentions sont très différents d'un pays à l'autre et nous essayons d'expliquer ces divergences à partir des éléments qui, selon le modèle retenu, sont à la base de ces intentions : attitude envers la création d'entreprises, normes sociales et contrôle comportemental perçu. Pour ce faire, nous proposons, en utilisant des techniques d'analyse des données, quatre facteurs (perception de la gestion du temps dans la vision de l'entrepreneuriat ; projection dans le future professionnel ; goût du risque dans la vie professionnel ; capacité perçue) qui structurent les intentions entrepreneuriales des étudiants, ainsi qu'une typologie qui montre des comportements quant aux intentions entrepreneuriales bien caractérisées et distinctes, entre d'une part, la France, et d'autre part, les autres pays.intentions entrepreneuriales ; étudiants ; France ; Pays arabes

L'intention entrepreneuriale : l'influence des facteurs liés à l'individu et au milieu

cahier de recherche n)2009-21 E4The entrepreneurial intent is the first element necessary in the entrepreneurial process. It reflects the will of a person start a business. This will be influenced by personality and beliefs of the individual on the environment. In this paper, we discuss primarily the economic Algeria environment. Then, we expose the Theoretical framework and conceptual our research. And finally, we describe a quantitative study with a sample of the city of Constantine in Algeria. This study proposed to explain the influence of factors related to individual and environment on the entrepreneurial intention.L'intention entrepreneuriale est le premier élément nécessaire dans le processus entrepreneurial.

Removal of heavy metals from Water Rinsing of Plating Baths by Electrodialysis

During the chromic plating of parts, the baths become more and more poor in chromic acid and rich in metallic impurities such as Cu2+, Zn2+, Fe3+ and Cr3+ which makes the bath useless. Also, the water used to rinse parts contains chromic acid and metallic impurities. As it is known that chromic acid is relatively expensive and very toxic, so its recovery has double interest: economic and environmental. Its reuse is possible after removal of metallic impurities. In this work, we studied the possibility of metallic impurities elimination from the chromic acid. The influence of the current density and the circulating solution flow rate on the process efficiency has been studied. The elimination rates obtained in the presence of ion exchange textile are superior to those obtained in the absence of textile. The analysis of the results showed that for the three metallic impurities studied (Cu2+, Fe3+ and Zn2+), the purification rate increases versus the applied current density and solution flow rate. The importance of the elimination of the three metal cations is as the following order: Cu2+ >Zn2+ >Fe3+

Structural behaviour of square RC columns confined with CFRP wraps

Loading capacity and strains of square reinforced concrete (RC) columns, strengthened with external carbon fiber reinforced polymer (CFRP) sheets, were tested and evaluated. The experimental parameters include: number of wrap layers, concrete strength and the slenderness of the columns (L/a). All test specimens were loaded to failure in axial compression. Compressive stress, axial and hoop strains have been recorded to evaluate the stress-strain relationship, ultimate strength, stiffness, and ductility of the specimens.Results clearly demonstrate that composite wrapping can enhance the structural performance of RC columns in terms of both maximum strength and ductility. The effects of test parameters are evidenced and compared

Phosphate ore washing by Na2EDTA for cadmium removal: Optimization of the operating conditions

This paper discusses the extraction of cadmium from phosphate ore by the washing method. Various parameters were investigated for the cadmium extraction from phosphate ore. The results from extraction tests showed that cadmium extraction depends on the nature and concentration of the extracting agent, the liquid/phosphate ore ratio, the temperature and the solution pH. The effi ciency of the nine extracting agents for removing cadmium from phosphate ore was found to be in the order: Na2EDTA > citric acid > tartric acid > ammonium citrate > calcium chloride > ammonium acetate > ammonium chloride > oxalic acid > ammonium hydroxide. In this study cadmium extraction kinetics was best described by the product layer diffusion control model
