Caractérisation des situations hydro-biologiques et potentialités de pêche thonière au Cap Lopez en Juin et Juillet 1972 et 1974

Surface temperature was measured by remote sensing through Cape Lopez (Gulf of Guinea) frontal region during the fishing season in June and July 1972 and 1974. Twelve typical situations are analysed through four main directions: surface situation, tendency, hydrobiological structure and availability to fisheries. The tuna behavior is analysed in relation with the frontal zone movements and a mechanism which tends to aggregate important shoals of tunas is presented.

Note sur l'évolution des populations de Copépodes pélagiques de l'upwelling mauritanien (mars-avril 1972)

The evolution of a plankton copepod population in the Mauritania upwelling was studied by following a drogue for 9 days, from the point of upwelling till the water-mass dives under offshore waters. The Shannon index of specific diversity and the tropic structure allow separation into several stages in the studied succession. The upwelling brings near the shore a rather poor, highly diverse fauna, with a low filter-feeder rate. The phytoplanktonic development induces an increase in the copepod number. The filter-feeders become dominant and the diversity decreases. When the increase of copepod number stops, the diversity decreases and the omnivore and carnivore rate increases.

Early marine growth in relation to marine-stage survival rates for Alaska sockeye salmon (Oncorhynchus nerka)

We tested the hypothesis that larger juvenile sockeye salmon (Oncorhynchus nerka) in Bristol Bay, Alaska, have higher marine-stage survival rates than smaller juvenile salmon. We used scales from returning adults (33 years of data) and trawl samples of juveniles (n= 3572) collected along the eastern Bering Sea shelf during August through September 2000−02. The size of juvenile sockeye salmon mirrored indices of their marine-stage survival rate (e.g., smaller fish had lower indices of marine-stage survival rate). However, there was no relationship between the size of sockeye salmon after their first year at sea, as estimated from archived scales, and brood-year survival size was relatively uniform over the time series, possibly indicating size-selective mortality on smaller individuals during their marine residence. Variation in size, relative abundance, and marine-stage survival rate of juvenile sockeye salmon is likely related to ocean conditions affecting their early marine migratory pathways along the eastern Bering Sea shelf.

Compreendendo a utopia realizável: uma defesa do ideal de justiça distributiva da teoria de John Rawls

O trabalho tem por objetivo articular uma defesa da teoria de justiça distributiva de John Rawls, considerando-se, para tal, as mudanças que o autor efetuou em sua teoria de justiça como equidade. Assim, a pesquisa tomará como base não somente o critério de justiça distributiva que se consolidou em Uma Teoria de Justiça, através do princípio da diferença, mas também avaliará de que forma este ideal continua presente nos textos posteriores do autor: O Liberalismo Político e O Direito dos Povos. Para tal, o estudo retomará as críticas cosmopolitas à proposta de internacionalização da teoria de justiça como equidade e, à luz destas, apresentará uma defesa do projeto de Rawls, evidenciando elementos do mesmo que estão alinhados ao projeto de justiça distributiva e sugerindo que sua proposta teórica é coerente com as premissas de Uma Teoria de Justiça, apesar de o princípio da diferença não estar presente entre os princípios fundamentais que devem ser estabelecidos entre os povos. Logo, trata-se também de uma proposta interpretativa que se vincula à compreensão (minoritária) de que as mudanças teóricas efetuadas por Rawls em sua teoria não a tornaram incompatível com seu projeto originário estabelecido em Uma Teoria de Justiça.

Educação e modernidade : o pensamento educacional dos Jesuítas, John Lock e Jean-Jacques Rousseau na era das ciências e da Filosofia Moderna

Esta pesquisa faz parte do eixo temático Educação e Cidadania, em sua linha de pesquisa Produção Social do Conhecimento, do Mestrado em Educação da Universidade do Estado do Rio de Janeiro - UERJ. É uma pesquisa bibliográfica. Trata de um estudo sobre a educação na Modernidade. Analisa três correntes do pensamento pedagógico dos séculos XVII e XVIII, que tiveram profunda repercussão em todos os sistemas educacionais do mundo ocidental, capaz de influenciar pedagogos e filósofos da educação na elaboração de propostas para a educação Moderna. Traz uma análise do pensamento educacional dos religiosos católicos jesuítas, de John Locke e de Jean-Jacques Rousseau, apontando visões pedagógicas particulares, muitas vezes antagônicas. Esboça uma síntese dos principais ideais dessas correntes de pensamento, que, com certeza iluminaram a produção do conhecimento educacional da Modernidade e as concepções pedagógicas contemporâneas. Em síntese, busca resgatar os ideais dessas três correntes de pensamento pedagógico e a sua contribuição na elaboração do conhecimento educacional e na formação da cultura do mundo ocidental; entende ser a apropriação desse conhecimento uma das formas de se ajudar a pensar a questão da cidadania.

Stanford University’s John Otterbein Snyder: Student, Collaborator, and Colleague of David Starr Jordan and Charles Henry Gilbert

John Otterbein Snyder (1867–1943) was an early student of David Starr Jordan at Stanford University and subsequently rose to become an assistant professor there. During his 34 years with the university he taught a wide variety of courses in various branches of zoology and advised numerous students. He eventually mentored 8 M.A. and 4 Ph.D. students to completion at Stanford. He also assisted in the collection of tens of thousands of fish specimens from the western Pacific, central Pacific, and the West Coast of North America, part of the time while stationed as “Naturalist” aboard the U.S. Fish Commission’s Steamer Albatross (1902–06). Although his early publications dealt mainly with fish groups and descriptions (often as a junior author with Jordan), after 1910 he became more autonomous and eventually rose to become one of the Pacific salmon, Oncorhynchus spp., experts on the West Coast. Throughout his career, he was especially esteemed by colleagues as “a stimulating teacher,” “an excellent biologist,” and “a fine man.

Seventh Annual Report for year ended 31st March, 1972

This is the seventh Annual report of the Cumberland River Authority on information of its activities and responsibilities on river management in its area between the beginning of April 1971, to the end of March 1972. The report contains 5 main sections on water resources, land drainage, fisheries, pollution, and finally the expenditure and income for the 12 month period. The first area that the report deals with is water resources, which includes periodical surveys, hydrometric schemes, acceptable flows, conservation works and a review of rainfall and river flow. The section on land drainage looks at work on improvement schemes, floods, charges and information on maintenance work carried out on rivers including Wampool, Waver, Derwent and Eden. The fisheries section covers 5 districts of the River Eden, Esk, Ellen, Derwent and South West Cumberland. It includes angling information and a general report for salmon and sea trout, brown trout and freshwater fish. Fish disease and fish hatchery are also covered as well as fisheries protection and licence duties. The fourth section on pollution deals with water quality, and the results of samples taken for chemical analysis from rivers Eden, Eamont, Petteril, Caldew, Calder, Irthing, Esk, Irt, Mite, Derwent, Ehen, Wampool and Waver are also given. It also covers information on sewage and trade effluents. The River Authorities preceded the Environment Agency which came into existence in 1996.

River Dart Scale Reading Investigation 1972

This is the River Dart Scale Reading Investigation Report on the 1972 season by the Devon River Board. The object of this investigation is to examine, by means of scale-reading, the general biology of the salmon population of the River Dart. In 1967 the final report on a five-year scale reading programme was summarised, at the time it was considered sufficient information to help with restocking programmes and the management of salmon population. But a further scale reading programme was started in an attempt to monitor changing patterns in salmon runs that may be caused by the new influences. It reviews the methods used for collection of the scales and examination of the materials. It shows the results of the survey and the number of scales studied from each of the various sea-age classes, time of running with distribution of the sea-age groups throughout the season, fish sizes and smolt ages at migration. All is summarized in tables, and figures are included showing weight distributions for each age classes and frequency distributions.

River Teign Fisheries Survey 1972

This is the Second River Teign Fisheries Survey from July and August 1972 by the Devon River Authority. The aim of the survey was to assess the distribution and relative abundance of salmonid fish in the River Teign, describing the methods and results. The section on methods contains information of the selected transects and methodology for the survey. The results goes through totals of all salmonid fish caught, adults, parrs and estimations of parr population individually for salmo salar and salmo trutta. Maps with survey sections and fish indices along with tables with size distributions and totals of salmonids found are attached.

River Exe Scale Reading Investigation. 7th Annual Report for the 1972 season

This is the 7th Annual Report of the Rive Exe Scale Reading Investigation for the 1972 Season by the Devon River Authority. The object of this investigation is to examine, by means of scale reading, the biology of age classes of the salmon population of the River Exe. It reviews the methods used for the collection of scales and examination of the materials. It shows the results of the survey and the number of scales studied from each of the various sea-age classes, time of running with distribution of the sea-age groups throughout the season, fish sizes and smolt ages at migration. All is summarized in tables, and figures are included showing weight distributions for each age classes and frequency distributions.

Salmon Scale Reading Investigation 1972

This is the Salmon Scale Reading Investigation from 1972 by Cornwall River Authority. The object of this investigation is to examine, by means of scale reading, the biology of age classes of the salmon populations of the River Tamar, River Tavy, River Lynher, River Fowey, River Camel and River Plym. It contains for each river the numbers of caught salmon, number of scales received and which were unreadable and percentages in each age group separately for net and rod caught. Length and weight frequency distribution histograms have been plotted to show the size distribution of the various sea age group.
