Ce mémoire étudie de façon empirique l'effet des dépenses publiques en biens et services sur le PIB à court et à long terme. Le sujet nous semble particulièrement pertinent dans le contexte de restrictions budgétaires qui est le nôtre. Dans une première étape, nous estimons les relations à court terme entre les dépenses publiques en biens et services G, le produit intérieur brut PIB et la masse monétaire M en mode bi-varié. Un modèle VAR en différence et des données trimestrielles pour la période 1947-1994 et les sous-périodes de change fixe (1947-1970) et de change flexible (1970-1994) sont utilisées. Nos résultats semblent confirmer la validité du modèle IS-LM-BP en économie ouverte avec mobilité des capitaux. À ce sujet, la distinction change fixe/change flexible s'est avérée cruciale. Les modèles de cycles réels ne peuvent expliquer nos résultats de manière satisfaisante, en particulier en ce qui a trait au rôle de la monnaie et au régime de taux de change. Dans une deuxième étape, nous estimons les relations à long terme entre les variables G et PIB au moyen de la procédure de cointégration proposée par Juselius et Johansen (1990). Nos résultats révèlent l'existence de relations stables à long terme entre les variables G et PIB, ce qui ouvre d'intéressantes perspectives. Entre autres, nos travaux confirment de façon empirique la loi de Wagner. De plus, le processus de socialisation de la fonction de production envisagée par Wagner, Schumpeter et d'autres semble toujours être à l'oeuvre.

As Voyages... são estudos completos, abrangendo todos os aspectos das regiões percorridas; servem de subsídio ao estudo das condições de vida no Brasil no século passado. "Fonte primordial de informações sobre os prédios coloniais do Rio de Janeiro, Minas Gerais, São Paulo, Santa Catarina e Goiás. Poucas obras no gênero atingem o valor de Saint-Hilarire. São clássicas e indispensáveis para o estudo do sul do Brasil, antes da Independência" segundo Borba de Moraes

The Centre de Recherches Océanographiques d'Abidjan has carried out the HYDROBIOCLIMAT program in order to study the seasonal and interannual fluctuations of the physical and biological parameters over the continental shelf of Ivory Coast ; two subsurface moorings with from one to three AANDERAA current meters fixed on the lines, were deployed in front of Abidjan and San Pedro. Temperature and current measurement records are presented at these two locations.

The results of floristic data collected during two surveys in the eastern region of Ebrié lagoon in 1987 (before the reopening of the inlet) and in 1988 (after the reopening of the inlet) are discussed in this article. Salinity increase (from 4‰ to 30‰) as a result of the reopening in September 1987 of the channel of Comoé river, profoundly modified qualitatively and quantitatively, the plant population. Floating or fixed macrophytes have been completely destroyed. Mangrove forest being the hydrophytic belt of the lagunar rives.

A wind-driven upwelling occurs on the continental shelf of Ivory Coast during the northern summer months; by studying the average conditions in the wind field, it has been found that in steady state the vertical speed upwards does not exceed 70 cm per day. The vertical flow per km super(2) is estimated in 46 m super(3)/s for a channel 50 m depth and in 92m super(3)/s for a channel 300 m depth. This study does not include the inclination of isopycnes in geostrophic adjustment with the variations of the Guinea current.

Stomach contents from 21 species of demersal fish caught on Grand Bassam (Côte d'Ivoire) fishing grounds at 20 and 35 m depth are analyzed. The results are compared with those of Longhurst (1957, 1960). The great importance of Crustacea in the food of those species appears clearly. A representative scheme of the diet is suggested.

21 surveys over the whole Ivorian continental shelf lead to a description of the phytoplankton repartition according to the different seasons: great and small cold seasons, discharge seasons, and warm seasons. Yearly means of surface cells concentrations range from 1000 to 30000 cells per liter, corresponding to a daily production of 386 to 1166 mg C/m2, according to regression analysis. These values make Côte d'Ivoire a rather rich region, which is subjected to wide standing crop variations.

An attempt was made to calculate zooplankton production from weights and settled volumes and from the life cycle of some copepods. Biomass data were recorded during several years from 24 monthly cruises and from a coastal station sampled biweekly. Dry weight data were directly measured or were calculated from the settled volumes using a linear regression. They range, on an average, from 0.965 to 5.56 g m-2 day-1 from the shore line to the edge of the continental shelf. The mean life-span of the cohorts of 12 species of copepods is about 20 days. It is assumed that only 1 spawn occurs per generation-time and that the standing stock is turned-over during the life span of a cohort. The production ranges from 48.2 to 278 mg dry weight m-2 day-1 or 17.9 to 103 mg C m-2 day-1, according to the depth of the studied areas. One third of carnivorous production occurs among the copepods. So, it is assumed that the herbivorous and omnivorous production is about 2/3 of the total zooplanktonic production. This would be a more accurate estimate of secondary production. The standing stock of zooplankton and fishes are in the same order of magnitude; the ratio zooplanktonic production/total fishery is 0.8%.

Ce guide a pour but de faire une présentation rapide de la Convention sur le travail dans la pêche qui a été adoptée en juin 2007 à Genève lors de la 96ème Conférence internationale du Travail (CIT) de l’Organisation internationale du Travail (OIT). Il ne prétend pas donner une interprétation de ses dispositions, ni remplacer la lecture du texte officiel. Il s’agit essentiellement d’aider ceux qui ne connaissent rien de ce nouveau document, et connaissent mal le fonctionnement de l’OIT et de la CIT, à se faire une idée des sujets traités. On espère que ce guide permettra notamment aux pêcheurs et à leurs organisations de comprendre les avantages potentiels et les répercussions de la nouvelle Convention sur la pêche artisanale et à petite échelle des pays en développement.
