Statistiques des peche des sardiniers ivoiriens - annee 1981

This publication shows the statistics of the sardinella fleet in 1981. These statistics are the catches and the effort by sector every two weeks. These data come also by month. At the end, ara listed the prices of the fresh fish in boxes at the criee. 1981 has been better than 1980, mainly for Sardinella aurita.

España neutral: el impacto económico de las dos guerras mundiales (1914-1945)

Durante las dos grandes guerras mundiales España adoptó una posición de no beligerancia que conllevaría a unas consecuencias y un impacto muy diferente para la economía española en uno y en otro conflicto. Por un lado España se presenta ante la Primera Guerra Mundial como una economía totalmente atrasada y agraria, mientras que con el estallido del conflicto supo aprovechar las necesidades del momento, permitiendo de esta manera un fuerte enriquecimiento. Por otro lado, en la Segunda Guerra Mundial España se encontraba totalmente destruida y con una fuerte inestabilidad, lo cual supuso que junto con las medidas autárquicas de la dictadura conllevaran a un periodo de penuria.

Juvenile salmon investigations River Wenning catchment 1981-86

As part of the River Lune juvenile salmonid investigation, a number of sites on the River Wenning catchment were electrofished annually from 1981 - 1985. Particularly low Salmon parr populations were evident for much of the Wenning catchment which has caused some concern. All the Wenning catchment electrofishing results are reported in this paper and comparisons are made with designated groups of sites on the remainder of the Lune catchment. These groups of sites are: River Lune and tributaries, upstream Tebay, Upper Middle Lune, Lower Middle Lune, Lower Lune, Birk & Borrow Becks, Chapel & Crosdale Becks, Rawthey system, Barbon & Leek Becks and the Greta system. The general scarcity of Salmonids in large sections of the main river Wenning probably reflects the apparent limited natural spawning areas on the catchment. Details of Salmon fry and ova planting on the Wenning catchment since 1981 have been collated and whilst survival through the 0+ stage appears to be quite good, recruitment to the 1++ stage appears to be poor. Water quality does not appear to be responsible for the very low salmonid densities at some main river sites but is possibly a factor in apparently preventing any Salmon run in Keasden Beck. Recommendations for future Fisheries and Biological work are given.

The juvenile salmonid populations of the River Lune catchment, 1981 to 1985

The aim of this study was to assess the status of the juvenile salmonid populations of the River Lune and its tributaries. There was special emphasis on juvenile salmon stocks in view of the implementation of a net limitation order in 1980. The number of licensed instruments were reduced as follows: (1) Drift, hang or whammel nets - from 12 to 10 (2) Draft or seine nets - from 3 to 1 (3) Heave or haaf nets - from 4 6 to 2 6 For the purpose of this report, the River Lune system has been divided into 13 subcatchments and these are examined with a view to detecting any trends in the data such as subcatchment productivity, partitioning between salmon and trout nursery streams, and whether the restrictions on salmon fishing had any discernible effects on juvenile salmon productivity. The effect of flow and instream obstructions on salmonid densities are also investigated as these have been shown to be important factors affecting abundance. Throughout the study period a programme of enhancement stocking took place primarily with salmon ova and fry. The possible impact of this on the results of the surveys has been assessed. The distribution and abundance of juvenile salmon was found to be relatively consistent in each of the 13 subcatchments studied over the 1981-1985 period.

A summary report on juvenile salmonid populations of the River Lune catchment, 1981 to 1991

This report summarises the fisheries electrofishing survey work undertaken on the River Lune, England, in the period 1981-85 and 1991. As part of a long term monitoring programme by the National Rivers Authority, juvenile surveys, with the emphasis on salmonids, have been carried out on the River Lune on a number of occasions since 1981. The latest survey in 1991 now gives the opportunity to assess what, if any, changes have occurred in the juvenile populations across the last 11 years and how future fisheries management may impact on the River Lune as a fishery. The areas of trout and salmon, fry and parr production will be considered in detail, as will adult trout populations. Water quality issues will be mentioned briefly as will habitat issues, where they are deemed to be important in affecting fish densities.

Noções para persuadir e educar: os discursos médico-higiênicos na formação e ofício do professorado primário (1914-1928)

O projeto de higienização, com efeitos sentidos ainda no século XIX, atravessou as primeiras décadas dos novecentos propondo intervenções cada vez mais incisivas na população brasileira, porém pautadas no princípio da educação higiênica. O pressuposto de que era necessário conscientizar e educar higienicamente a população, ao invés de impor apenas a obediência a medidas legislativas, tornou a escola primária um dos principais escopos das iniciativas em proveito da formação de hábitos sadios. Este olhar sobre a escola primária exigiu do professorado o preparo para lidar com tais desafios. Esta dissertação situa- se no âmbito da proposta de refletir acerca da interferência dos discursos e conhecimentos médico-higiênicos na formação e ofício da docência primária. Para tal efeito, tomamos como algumas das principais fontes os compêndios escolares de higiene, endereçados às escolas normais, bem como os programas da disciplina, produzidos para conduzir o ensino na Escola Normal do Distrito Federal. Tendo em vista que este aparato didático-pedagógico, composto pelos compêndios e pela disciplina de Higiene, manteve forte relação com o que se difundiu acerca do professorado primário a respeito de seu papel na campanha higiênica , também fez parte da perspectiva deste estudo o exame dos discursos proferidos nos congressos médicos e educacionais. Tais discursos nos auxiliaram no sentido de perceber a retórica que requisitava o alargamento do papel do professorado primário, no contexto das primeiras décadas do século XX, impulsionando uma suposta adequação do plano de formação docente às emergências da saúde pública. Ademais, as iniciativas voltadas para o aperfeiçoamento dos professores primários, fora das escolas normais, também se expressaram como discursos destas novas atribuições: tratamos dos cursos de aperfeiçoamento em higiene, promovidos por instituições distintas. Tornava-se necessário disciplinar a infância e suscitar nela novos hábitos. Portanto, os professores primários foram convocados a se constituírem braços direitos dos higienistas.

Intelectuais nas trincheiras: a Liga Brasileira pelos Aliados e o debate sobre a primeira guerra mundial (1914-1919)

Esta dissertação procura compreender a atuação e o discurso da Liga Brasileira pelos Aliados, associação fundada com o propósito de apoiar a campanha dos Aliados na Primeira Guerra Mundial. Pretende-se analisar sua estrutura de funcionamento e formas de atuação para promover a campanha daquele bloco de combatentes ao longo do conflito europeu. Através dos boletins, artigos e moções publicados na imprensa carioca, observa-se a elaboração de um discurso com o intuito não apenas de persuadir a opinião pública brasileira a favor dos Aliados, mas de estabelecer uma representação da nação brasileira na Primeira República.
