O golpe militar de 1964 envolveu, acima de tudo, uma disputa de modelos de desenvolvimento para o Brasil. De um lado, setores que defendiam o progresso a partir do fortalecimento da indústria nacional, da realização da reforma agrária e de maior independência em relação ao capital internacional. Do outro, estavam o empresariado nacional ligado a multinacionais, que defendia maior vínculo com o capital estrangeiro, e grandes proprietários rurais. A partir da posse de Jango, em 1961, as forças conservadoras iniciaram uma organizada campanha ideológica que envolveu apoio político e financeiro de empresários e do governo norte-americano, e mobilização de setores importantes da classe média, das Forças Armadas e da imprensa, com o objetivo de derrubar o governo. Em março de 1964, a organização das forças conservadoras realizou manifestações populares pediam a intervenção militar. Com o advento do golpe, Jango tinha que reagir contra forças que haviam conquistado significativa parcela da população ou abrir mão de qualquer reação e partir para o exílio e retornar mais tarde pelas vias democráticas. Jango fez a opção pelo recolhimento. Não renunciou. O trabalho tem o propósito de entender os motivos que levaram João Goulart à decisão de não reagir ao golpe de 64.

During a 1995 aerial video survey of the coastline of Johnstone Strait, an unusual shoreline feature was noted and termed “clam terraces” (inset) because of the terrace-type morphology and the apparent association with high clam productivity on the sandflats. Typical alongshore lengths of the terrace ridges are 20-50m, and across-shore widths are typically 20-40m. An area with an especially high density of clam terraces was noted in the Broughton Archipelago, between Broughton and Gilford Islands of southeastern Queen Charlotte Strait. Clam terraces in this area were inventoried from the aerial video imagery to quantify their distribution. The terraces accounted for over 14 km of shoreline and 365 clam terraces were documented. A three-day field survey by a coastal geomorphologist, archeologist and marine biologist was conducted to document the features and determine their origin. Nine clam terraces were surveyed. The field observations confirmed that: the ridges are comprised of boulder/cobblesized material, ridge crests are typically in the range of 1-1.5m above chart datum, sandflats are comprised almost entirely of shell fragments (barnacles and clams) and sandflats have very high shellfish production. There are an abundance of shell middens in the area (over 175) suggesting that the shellfish associated with the terraces were an important food source of aboriginal peoples. The origin of the ridges is unknown; they appear to be a relict feature in that they are not actively being modified by present-day processes. The ridges may be a relict sea-ice feature, although the mechanics of ridge formation is uncertain. Sand accumulates behind the ridge because the supply rate of the shell fragments exceeds the dispersal rate in these low energy environments. The high density areas of clam terraces correspond to high density areas of shell middens, and it is probable that the clam terraces were subjected to some degree of modification by aboriginal shellfish gatherers over the thousands of years of occupation in the region.

Diking and holding water on salt marshes ("impounding" the marsh) is a management technique used on Merritt Island National Wildlife Refuge (MINWR) and elsewhere in the Southeast to: a) prevent the reproduction of saltmarsh mosquitos, and b) attract wintertering waterfowl and other marsh, shore, and wading birds. Because of concern that diking and holding water may interfere with the production of estuarine fish and shellfish, impoundment managers are being asked to consider altering management protocol to reduce or eliminate any such negative influence. How to change protocol and preserve effective mosquito control and wildlife management is a decision of great complexity because: a) the relationships between estuarine organisms and the fringing salt marshes at the land-water interface are complex, and b) impounded marshes are currently good habitat for a variety of species of fish and wildlife. Most data collection by scientists and managers in the area has not been focused on this particular problem. Furthermore, collection of needed data may not be possible before changes in protocol are demanded. Therefore, the purpose of this document is two-fold: 1) to suggest management alternatives, given existing information, and 2) to help identify research needs that have a high probability of leading to improved simultaneous management of mosquitos, waterfowl, other wildlife, freshwater fish, and estuarine fish and shellfish on the marshland of the Merritt Island National Wildlife Refuge.

A study on the reproductive biology of Amblema neislerii, Elliptoideus sloatianus, Lampsilis subangulata, Medionidus penicillatus, and Pleurobema pyriforme was conducted from May 1995 to May 1997. The objectives of this study were as follows: 1) determine period of gravidity for each of the five mussel species, 2) determine host fish via laboratory experiments, 3) test whether unionid glochidia will transform on a nonidingenous fish, and 4) describe the glochidial morphology for each of the five mussel species using a scanning electron microscope. Amblema neislerii are tachytictic breeders and were found with mature glochidia in May. Elliptoideus sloatianus are tachytictic breeders and were found with mature glochidia from late February to early April. Lampsilis subangulata are bradytictic breeders and were found with mature glochidia from December to August. Superconglutinates were released by L. subangulata from late May to early July. Medionidus penicillatus are bradytictic breeders and were found with mature glochidia in November and February to April. Pleurobema pyriforme are tachytictic breeders and were found with mature glochidia from March to July. The following fish species served as hosts for A. neislerii: Notropis texanus, Lepomis macrochirus, L. microlophus, Micropterus salmoides, and Percina nigrofasciata. The following fish species served as hosts for E. sloatianus: Gambusia holbrooki, Poecilia reticulata, and P. nigrofasciata. The following fish species served as hosts for L. subangulata: G. holbrooki, P. reticulata, L. macrochirus, Micropterus punctulatus, and M. salmoides. The following fish species served as hosts for M. penicillatus: G. holbrooki, P. reticulata, Etheostoma edwini, and P. nigrofasciata. The following fish species served as hosts for P. pyriforme: Pteronotropis hypselopterus, G. holbrooki, and P. reticulata. Poecilia reticulata, a nonindigenous fish, served as a host for E. sloatianus, L. subangulata, M. penicillatus, and P. pyriforme. (76 page document)

Analisa o fenômeno da má redação das leis sob a ótica do processo legislativo, a partir do exame das etapas de elaboração e de votação da Redação Final das proposições sujeitas à apreciação do Plenário da Câmara dos Deputados. O objetivo é verificar se as incoerências textuais, de forma e de conteúdo, são ocasionadas também pela votação da redação presumida, a par da inobservância das regras e preceitos de Técnica Legislativa. O trabalho mostra que a prática da votação da redação presumida pode provocar lapsos e incoerências no texto final, pelo encerramento da apreciação da matéria sem a possibilidade de sanear erros materiais ou formais porventura existentes. Além disso, propõe que a própria legitimidade do processo e, por conseguinte, do ato legislativo final, estaria maculada, pela impossibilidade de se atestar a conformidade entre a Redação Final e o real conteúdo deliberado pelo Plenário, podendo o texto não espelhar a real intenção do legislador. O trabalho inicia com as noções de Técnica Legislativa, de forma a caracterizar a importância do aspecto formal e da adequada apresentação escrita das proposições legislativas. Em seguida, descreve o atual processo de elaboração e de votação da Redação Final e as suas consequências para a redação e a legitimidade dos textos legais. Para isso, foram analisadas diversas Questões de Ordem acerca do assunto e realizada uma breve pesquisa, que contempla as proposições aprovadas pelo Plenário neste ano de 2011 (até 26/10/11), para verificar a quantidade de modificações introduzidas e a possibilidade de ocorrência de deficiências redacionais em razão da não apresentação do texto da Redação Final antes de considerá-lo definitivamente aprovado. Na sequência, faz um estudo de caso do processo de votação da Lei da "Ficha Limpa". Por fim, apresenta proposta de modificação, no sentido de contribuir para o debate e consequente aperfeiçoamento do referido processo.

One of the causes of lower artesian pressure, water waste and aquifer contamination is the misuse and insufficient care of artesian wells. In 1953, Senate Bill No. 57, entitled "An Act to Protect and Control the Artesian Waters of the State" (see Appendix) became a law. This law was passed through the efforts exerted by leading members of the Senate and the House of Representatives, who understood the need for a wise and controlled expenditure of our most valuable natural resource. The State Geologist and his authorized representatives were designated by this law to enforce this conservation measure; however, no financial provision was included for the 1953-55 biennium. The proposed program of the Florida Geological Survey for this biennium did not include the funds nor provide any full-time personnel for the enforcement of this statute. As a result, little actual work was accomplished during these two years, although much time was given to planning and discussion of the problem. Realizing that this program could provide additional basic data needed in the analysis of the water-supply problem, the State Geologist sought and was granted by the 1955 Legislature adequate funds with which to activate the first phase of the enforcement of Florida Statute No. 370.051-054. Enumerated below is a summary of the progress made on this investigation as outlined previously: 1. Data have been collected on 967 wildly flowing wells in 22 counties. 2. Chloride determinations have been run on 850 of the 967 wells. 3. Of the 967 wells, 554 have chlorides in excess of the 250 ppm, the upper limit assigned by the State Board of Health for public consumption. 4. Water escapes at the rate of 37, 762 gallons per minute from these 967 wells. This amounts to 54, 377, 280 gallons per day. The investigation is incomplete at this time; therefore, no final conclusions can be reached. However, from data already collected, the following recommendations are proposed: 1. That the present inventory of wildly flowing wells be completed for the entire State. 2. That the current inventory of wildly flowing wells be expanded at the conclusion of the present inventory to include all flowing wells. 3. That a complete statewide inventory program be established and conducted in cooperation with the Ground Water Branchof the U.S. Geological Survey. 4. That the enforcement functions as set down in Sections 370.051/.054, Florida Statutes, be separated from the program to collect water-resource data and that these functions be given to the Water Resources Department, if such is created (to be recommended by the Water Resources Study Commission in a water policy law presented to the 1957 Legislature). 5. That the research phase (well inventory) of the program remain under the direction of the Florida Geological Survey. (PDF contains 204 pages.)
