L’objectif de la présente étude est d’explorer la « géographie imaginaire » du roman Le Ventre de l’Atlantique, écrit par Fatou Diome. Le concept de la « géographie imaginaire » décrit les rapports de domination spatiale et la construction d’un « Autre », entièrement différent de « nous » (Saïd, 1980). Les deux pays du roman, la France et le Sénégal, sont analysés comme deux sphères inconciliables, associées aux oppositions comme nous – l’Autre, individualisme – collectivisme, rationalité - superstition. Deux images spatiales sont discutées dans ce mémoire: l’île Niodior au Sénégal et l‘océan Atlantique. L’isolation de l’île Niodior renforce la séparation en deux espaces opposés, alors que l’Atlantique constitue un élément parfois chargé de forces magiques, lié à la vie et à la mort. Evoquant l’idée d’hybridité, le roman montre également des espaces et des identités alternatifs, qui transgressent la structure coloniale.

[FR] Grande figure de la géographie française —et européenne— du premier quart du XIXe siècle, Conrad Malte-Brun laisse une oeuvre scientifique écrite considérable, dont une vaste Géographie universelle qui marqua alors son époque, rééditée à de multiples reprises durant plus de 50 ans. Contrairement à Élisée Reclus, autre grande figure de la seconde moitié du XIXe siècle, les écrits de Malte-Brun demeurent mal connus, sinon mésestimés. Or, à travers le fil conducteur que représente le chapitre de sa Géographie universelle consacré à l’Espagne, nous avons pour objectif de montrer que son auteur a su dépasser la simple dimension descriptive caractérisant nombre de textes géographiques de son époque pour introduire une réelle dimension explicative. Rien que pour cela, il mérite très largement, à notre sens, d’être redécouvert…

La Nouvelle Géographie Universelle di Élisée Reclus relativizza e problematizza il ruolo dell’Europa e il suo peso nello scacchiere mondiale, restando tuttavia in equilibrio fra, da una parte, la critica delle pratiche coloniali e dall’altra la fiducia nei confronti della tradizione culturale proveniente dall’antica Grecia e dal secolo de Lumi destinata, nella visione evoluzionista dell’autore, a spargere negli altri continenti i germi del pensiero socialista e anarchico. In questo lavoro si cerca di chiarire questa rappresentazione dei concetti di Europa e Occidente in tre passaggi successivi. Dapprima, la ricostruzione della genealogia, della teoria e del contesto storico del concetto di geografia universale all’epoca. Poi, la ricostruzione dalle fonti di archivio delle reti scientifiche di respiro europeo che sono state alla base di quest’opera, indispensabile per poterne comprendere il significato politico nel contesto dell’epoca. Infine, l’indagine sul testo per ricostruire ruolo, caratteri e suddivisione dell’Europa, che si rivela, nonostante la serrata critica del suo ruolo colonizzatore, come il privilegiato laboratorio individuato dai “geografi anarchici” per lo sviluppo delle lotte sociali e per la costruzione, su basi anche geografiche, di una proposta politica federalista e libertaria.

The aim of the study is to contribute to the knowledge and the identification of the main physical and chemical characteristics of the soil that affect the structural stability of soil types forming the soil cover of the plain of Sidi Bel Abbes region for agricultural use by excellence. Structural stability is an indicator of the cohesion of soil aggregates. This is a parameter that expresses the ability of soil aggregates to resist degradation in general the impact of rain or excess water. Measuring the structural stability makes it possible to evaluate the sensitivity a soil crusting and erosion. The results showed that soils subject of our study are stable and very stable with a slight difference. We have a statistical study made it possible to establish a correlation between the structural stability and other physical and chemical soil parameters measured )fersiallitic red soil and brown calcareous soil( such as organic matter content, the rate of total limestone and soil texture, to better explain the stability or instability of the soil structure and to establish a relationship between these parameters and the structural stability. // Keywords: Sidi Bel Abbes, chemical characteristics, physical, structural stability, soil, plain, fersiallitic red soil, brown calcareous soil

This article analyzes the Jakobsonian classification of aphasias. It aims to show on the one hand the non-linguistic character of this classification and on the other hand its asymmetry, in spite of the fact that its author had conceived his structural construction as symmetrical. The non-linguistic character of Jakobson’s formulation is due to the absence of any definition of language, this absence being the main characteristic of Jakobsonian linguistics: concerning the aphasia problem, the Jakobsonian formulation is linguistic solely by virtue of its object, aphasia, which is already considered as a linguistic concern because it belongs to the field of « language », but which is not defined as such (as linguistic). As for asymmetry, it demonstrates first the circularity of the Jakobsonian representation of language (the duality between structure and functioning), and secondly the non-linguistic character – in the Saussurean sense of the term – of the aphasia problem. Thus it appears that breaking (in the sense of Gaston Bachelard) with idiom is the prerequisite of a scientific apprehension of language, and therefore of any interdisciplinarity, this being one of Jakobson’s favorite topics but one that this linguist failed to render fruitful because he did not offer a real definition of language.
