Innovation Determinants in Emerging Countries: An Empirical Study at the Tunisian Firms level
Explaining why some firms innovate and some others do not is an out-of-date challenge in the economic literature. In developing countries context, such exercise is even more complicated by the nature of the innovation (incremental, occasional and rarely continuous and structured). In this paper, an exploratory tentative logistic regression is presented based on an Innovation survey on Tunisian firms. With regard to the results on the two "traditional" determinants of innovation which are the size of firms and the market structure, the main findings of this work are the following: econometric estimations have put forward the existence of an inverted "U" type relationship between decision to innovate and these two variables. On the other hand, it seems that neither skills of workers nor public incentives were significant to explain the innovation behaviour of Tunisian firms.Industry dynamics; Innovation systems; Development economics; Sectoral systems of innovation
Information juridique, sa forme et ses supports : bilan réalisé à partir de l\u27étude du fonds de la bibliothèque droit et gestion de Lyon 3 (L\u27)
: Etude de cas : la Tunisie
This article focuses on the network analysis of the contemporary art in Tunisia, through a dual approach that is both egocentric (centered on the individual) and intermediate (interaction between individuals). Starting with a series of interviews with actors who belong to the world of Tunisian art (artists, gallerists and curators), we propose a comprehensive approach to the process of structuring the network of Art, in its context of creation, mediation, reception and transnational exchanges.Cet article se concentre sur l'analyse du réseau de l'art contemporain en Tunisie, à travers une double approche à la fois égocentrique (centré sur l'individu) et intermédiaire (interaction entre les individus). A partir d'une série d'entretiens auprès des agents du monde de l'art tunisien (artistes, galeristes et commissaires d'exposition), il s'agit de proposer une démarche compréhensive du processus de structuration du réseau artistique dans son contexte de création, de médiation, de réception et d'échanges transnationaux
Trials and Tribulations of Sla Framework in Designing Arabic Courses for Speakers of Other Languages
There is a consensus among language teachers and researchers that language course design is always a work in progress. This is influenced by variables such as the type of language being taught and whether the teaching of this language has been researched. Arabic is one the languages that have created a perennial debate among its teachers about the anticipated challenges pointing principally to three reasons. The first reason refers to the dichotomy that exists between MSA and Colloquial Arabic, which will have a direct impact on teaching the macro-skill of ‘speaking’. The second reason deals with the complexity of MSA in terms of grammar. The final reason discusses the theoretical aspects of language teaching and learning and its implications to the design of the Arabic program. This paper discusses these problems stemming from the recent empirical pilot study of teaching Arabic for a specific purposes (ASP). The study exposes some the problems mentioned above and suggests solutions to improve the teaching of Arabic in the light of theories of SLA and language teaching and learning

Analyse économique de la pauvreté en Tunisie : approche monétaire et multidimensionnelle
The aim of this thesis is to analyze the evolution of poverty and identify the socio-economical groups as well as the dimensions that contribute to it in Tunisia following a monetary approach and also a multi-dimensional one. For this reason, I adopt a method which consists in using the approach of stochastic dominance and the theory of fuzzy sets. That is to say, I adopt some of the different methods which have been adopted in the previous studies that were interested in Tunisia. Three main conclusions emerge from the exploitation of data based on two national surveys of the budget and the consumption of households 2005, 2010 and another national survey of the family health 2006. In fact, the first one reveals the decrease of poverty at the national level despite that there are disparities that still persist between rural and urban areas and between the coastal regions and the regions of the interior as well. The second survey puts in evidence that the effects of redistributive policies in Tunisia have not accelerated the pace of poverty reduction. As for the third survey, it suggests that taking into account the multi-dimensional aspect of poverty reveals the existence of other important dimensions in relationship with poverty that constitute an obstacle to a decent life for the Tunisian households.Cette thèse se propose d’analyser l’évolution de la pauvreté et d’identifier les groupes socio-économiques ainsi que les dimensions qui contribuent le plus à l’évolution de la pauvreté en Tunisie en nous appuyant sur une approche monétaire et une approche multidimensionnelle. Pour cela, nous adoptons une méthodologie qui consiste à utiliser l’approche de dominance stochastique et la théorie des ensembles flous, c’est-à -dire des méthodes différentes de celles adoptées dans les études antérieures qui s’intéressent à la Tunisie. Trois principales conclusions ressortent de l’exploitation des données issues de deux enquêtes nationales sur le budget et la consommation des ménages 2005, 2010 et d’une enquête nationale sur la santé de la famille 2006. La première révèle une diminution de la pauvreté au niveau national bien que de fortes disparités persistent encore entre le milieu rural et le milieu urbain, et entre les régions du littoral et les régions de l’intérieur. La deuxième met en évidence les effets des politiques de redistribution en Tunisie qui n’ont pas permis d’accélérer le rythme de réduction de la pauvreté. La troisième suggère que la prise en compte de l’aspect multidimensionnel de la pauvreté révèle l’existence d’autres dimensions importantes en relation avec la pauvreté et qui constituent un obstacle à une vie décente pour les ménages tunisiens

Optimisation Géométrique d'une Machine à Commutation de Flux à Aimants Permanents en utilisant un Modèle Analytique Magnéto-Acoustique
Cet article présente les résultats d'une optimisation de la géométrie des Machines à Commutation de Flux à Aimants Permanents (MCF-AP) basée sur des critères multi-physiques magnéto-acoustiques en utilisant un modèle entièrement analytique visant à prédire le fonctionnement magnétique, mécanique et acoustique de ces structures. L'optimisation est réalisée sur une structure triphasée 12/10 et sur une structure pentaphasée 20/18 pour une alimentation et une vitesse donnés. Le modèle analytique, présenté et validé expérimentalement, permet un gain de temps non négligeable dans la prédiction des phénomènes magnéto-acoustiques en comparaison d'un modèle éléments finis et permet naturellement son implémentation dans un algorithme d'optimisation
