The effects of temperature on growth and metabolism of flowing water cold-stenotherms [Translation from: Archiv fur Hydrobiologie 74(4) 479-495, 516-522, 1974]

A small stream in the French Alps was sampled at regular intervals to determine the size distribution of animals for growth studies. The temperature was also measured. The results obtained for Gammarus fossarum were compared with laboratory cultures and the laboratory animals were physiologically and chemically analysed. Chemical analysis was also carried out on field animals.

Selective plankton feeding by the coregonid ”bondella” (Coregonus sp.) of Lake Maggiore [Translation from: Translation from: Memorie dell'Istituto Italiano di Idrobiologia Dott.Marco de Marchi 31 181-203, 1974]

In recent times, some specialists have begun to study the subject of food selection of fish in an organized way, thus highlighting its importance. In the present work, the author intends to evaluate the impact of predation on the eupelagic zooplanktonic biocenosis of Lake Maggiore, producing, in this way, as far as possible, a basis for a better understanding of the population dynamics of the species of zooplankton directly involved. Another aspect which has been studied is that related to the mechanism of selective capture set in action by the predator. To this end the study tries to bear in mind that the subject should be interpreted as a function of numerous factors acting contemporaneously, that is as the interaction of characters peculiar to the predator and to the prey. The species studied, locally called ”bondella”, belongs to the family Salmonidae, subfamily Coregoninae and was introduced into Lake Maggiore in 1950.

Profile soundings in lakes of the younger morainal area of Sleswick-Holstein with a sediment-echo-sounder of 30 kHz [Translation from: Wass.Boden 26, 135-138, 1974]

To be able to carry out physical, chemical and biological investigations on a lake, one needs a thorough knowledge of the volume of water and the shape of the lake basin. Little is known about the about the morphology of the lakes in Schleswig-Holstein and its ecological consequences. For this research a 30 KHz echo sounder with sediment transceiver was used to carry out profile determinations (echo soundings). This apparatus continuously records on paper the different reflexions and absorptions of the sediment and water body in the corresponding depth. By this, acoustically noticeable layers and different densities in the sediment and 'scattering layers' in the water body due to physical, chemical and biological reasons (e.g. plans and single fish) are made visible. Result are summarised here regarding the echo soundings in Blunker See.

Concerning the current conditions and transport of sand in the shallow water areas off the coast of the south-eastern North Sea [Translation from: Hamburger Kustenforschung 29 [pages 41-43 only], 1974]

With the aid of the German Research Association in the central programme 'Sand movements in the German coastal region', an investigation into the current conditions in the shallow water areas of the coasts of the south-eastern North Sea between Sylt and the Weser estuary was carried out by the author. Foundations of the work are 19 continuous current recordings in five profiles normal to the coast from years 1971 to 1973. Off the coasts of the south-eastern North Sea varying tidal currents impinge; they are currents whose directions may vary periodically through all points of the compass. They are caused by the circulating tides in the North Sea (Amphidromien). The turning flow movement experiences a deformation in the very shallow coastal waters, and as it happens the flow turning movement in the case of high tide continues right up onto the outer flats, while here and in the fore-lying shallow water areas around the time of low water (on account of the small depths of waters), there prevails a more variable current. A result of this hydrodynamical procedure is the development of counter currents. This partial translation of the original paper provides the summary of this study of of the mudflat areas between the Elbe and Weser.

Report of the Inter-American Tropical Tuna Commission for the year 1974

ENGLISH: The Inter-American Tropical Tuna Commission operates under the authority and direction of a convention originally entered into by the Republic of Costa Rica and the United States of America. The convention, which came into force in 1950, is open to adherence by other governments whose nationals fish for tropical tunas in the eastern Pacific Ocean. Under this provision the Republic of Panama adhered in 1953, the Republic of Ecuador in 1961, the United Mexican States in 1964, Canada in 1968 and Japan in 1970. In 1967, Ecuador gave notice of her intent to withdraw from the Commission, and her withdrawal became effective on August 21,1968. SPANISH: La Comisión Interamericana del Atún Tropical está bajo la autoridad y dirección de una convención la cual fue originalmente formada por la República de Costa Rica y los Estados Unidos de América. La Convención, vigente desde 1950, está abierta a la afiliación de otros gobiernos cuyos nacionales pesquen atún en el Pacífico oriental tropical. Bajo esta medida la República de Panamá se afilió en 1953, la República del Ecuador en 1961, los Estados Unidos Mexicanos en 1964, Canadá en 1968 y el Japón en 1970. En 1967, el Ecuador anunció su intención de retirarse de la Comisión y la renuncia se hizo efectiva el 21 de agosto de 1968.(PDF contains 170 pages.)

Ecological study of chalk and limestone streams. Annual Report October 1974 to September 1975

Few detailed studies have been made on the ecology of the chalk streams. A complex community of plants and animals is present and much more information is required to achieve an understanding of the requirements and interactions of all the species. It is important that the rivers affected by this scheme should be studied and kept under continued observation so that any effects produced by the scheme can be detected. The report gives a brief synopsis of work carried out during the second year of a four year ecological study sponsored jointly by the Thames Water Authority and the Central Water Planning Unit. It assumes some familiarity with the investigations carried out on the River Lambourn during the preceding three years which was sponsored jointly by the Thames Conservancy and Water Resources Board (immediate predecessors of the present sponsoring organisations).

A internacionalização privada na onda estatizante: as relações público-privadas na internacionalização das empreiteiras brasileiras entre 1974-1979

Durante a década de 1970, ocorreu, no Brasil, a fase pioneira de internacionalização das empresas privadas brasileiras do setor de prestação de serviços de engenharia de construção. Essa internacionalização deu-se, apesar da ausência de uma política estruturada do setor público. A incapacidade estatal de perceber esse processo como algo profícuo em seus planos, impediu o governo de criar uma política consolidada para a multiplicação dessas empresas no exterior. Essa miopia estatal é percebida tanto na esfera da política doméstica, voltada para manter uma política de substituição de importação dentro das fronteiras, como, na política externa, ao desenvolver uma internacionalização das empresas públicas ao invés das do setor privado. Essa situação pode ser percebida no caso analisado da empresa privada brasileira Mendes Júnior, que ingressou no mercado iraquiano mais por conta própria do que em decorrência de uma política estatal brasileira.

A organização da mocidade portuguesa: entre rupturas e permanências (1943-1974)

O Estado Novo Português (1932-1974) foi um dos mais duradouros regimes ditatoriais durante o Século XX. Oliveira Salazar, seu principal governante, importava-se com a manutenção das instituições de representação social, principalmente as representadas pelo lema: Deus, Pátria e Família, ou seja, a Igreja, a Nação (Império) e a Família. Esta última representava a base de toda a moral, ordem e harmonia do país, assim como os jovens destas famílias representavam o futuro da Nação. A Organização Nacional Mocidade Portuguesa fora instituída pelo decreto-lei n. 26.611, de 19 de maio de 1936, em execução da lei n. 1.941, de 11 de abril do mesmo ano pelo Ministro da Educação, Antônio Faria Carneiro Pacheco. Ela representava toda a juventude do país dos sete aos vinte e cinto anos, escolar ou não, e tinha por finalidade estimular o desenvolvimento integral da capacidade física, formação do caráter e a devoção à Pátria, no sentimento da ordem, disciplina e no culto do dever militar.

A demanda por moeda no Brasil no período 1974-2008: estimativas sob expectativas adaptativas e racionais

O objetivo principal desta dissertação é analisar a demanda por moeda no Brasil no período 1974 a 2008, lembrando que ele inclui sub-períodos de inflação elevada, e baixa, e levando em conta hipóteses alternativas quanto à formação de expectativas. A especificação adotada é a de Tourinho (1995), que generaliza a de Cagan (1956) para permitir uma forma funcional mais flexível e incorporar outras variáveis, além da inflação esperada, como variáveis explicativas. Verifica-se que estas extensões são importantes para modelar a demanda por saldos monetários reais no período aqui considerado. A forma funcional semi-log de Cagan é rejeitada, em favor de uma forma funcional flexível Box-Cox, e os coeficientes da taxa de juros real e da variância da inflação são significativos, mostrando a importância destas variáveis serem inseridas ao modelo. A função estimada para o período completo é comparada com aquelas estimadas para os sub-periodos de inflação alta e moderada, para verificar a estabilidade da formulação adotada. Conclui-se que se pode rejeitar a hipótese de que ela é estável. O modelo de Cagan é generalizado aqui em outra dimensão, considerando mecanismos alternativos de formação de expectativas, que podem ser adaptativas, como no modelo original, ou racionais. A hipótese de que expectativas adaptativas sejam racionais é também considerada. Conclui-se que a imposição da condição de racionalidade ao modelo com expectativas adaptativas não produz alterações importantes nos valores estimados.
