This study was designed to evaluate the travel characteristics of avid marine anglers off Louisiana in the Central Gulf of Mexico. It focuses on the complex marine travel patterns involving the extensive assemblage of oil and gas structures. In an intercept approach, marine recreationalf isherman were asked to identify near and offshore travel patterns on the day of the interview. Information was also solicited regarding how respondents selected and located fishing destinations as well as what method of fishing was undertaken that day. Petroleum platforms were a principal fishing destination, and platform anglers traveled an average distance of 75.5 km (40.7 n.mi.) to and from offshore fishing locations. In fishing an average of 6.5 platforms per trip, these anglers traveled about 21.3 km (11.5 n.mi.) between the first and last platform visited. Mean total distances for platform anglers were 96 km (51.8 n.mi). Travel distances for bay, nearshore, and bluewater anglers were also obtained.

Basking sharks, Cetorhinus maximus, are frequently observed along the central and northwestern southern California coast during the winter and spring months. These large plankton feeding elasmobranchs, second in size only to the whale shark, Rhineodon typus, had been the subject of a small commercial fishery off California in the late 1940's and early 1950's for their liver oil, rich in vitamin A, and in later years for reduction into fish meal and oil (Roedel and Ripley, 1950). These fisheries were sporadic and did not take basking sharks in large numbers.

O objetivo deste trabalho foi avaliar morfometricamente as modificações ocorridas ao longo de 500 anos nas estruturas maxilo-mandibulares de indivíduos da Costa Central do Peru. Foram utilizadas telerradiografias laterais de 30 crânios secos, sem deformidades esqueléticas e em normoclusão, do período Pré-colombiano (grupo Pré-colombiano) e de 30 peruanos nativos contemporâneos, com características esqueléticas e oclusais semelhantes, provenientes da mesma região geográfica (grupo Contemporâneo). Estas telerradiografias foram digitalizadas e 14 pontos cefalométricos foram marcados e utilizados como marcos anatômicos homólogos para a análise morfométrica. O tamanho do centróide, a forma e a alometria foram comparados entre os grupos para a amostra total, para homens e para mulheres, pelos testes de one-way ANOVA, função discriminante e regressão multivariada, respectivamente. As mesmas avaliações foram realizadas para homens e mulheres do mesmo grupo. O tamanho do centróide foi significativamente maior para o grupo Contemporâneo tanto para a amostra total, quanto para homens e mulheres, demonstrando que as estruturas maxilo-mandibulares dos indivíduos contemporâneos é maior do que de seus ancestrais. Quando homens e mulheres foram comparados intra-grupos o tamanho do centróide foi significativamente maior para os homens do grupo Contemporâneo, com a mesma tendência para os homens pré-colombianos, porém sem significância estatística. Observou-se diferenças significativas entre os grupos para a forma das estruturas maxilo-mandibulares indicando que ao longo do tempo houve um deslocamento posterior da região da pré-maxila e um deslocamento considerável para cima e para trás da apófise coronóide, uma abertura do ângulo na região goníaca e um alongamento no sentido vertical da região da sínfise mandibular. Essas mudanças morfológicas foram mais evidentes nas mulheres do que nos homens, parecendo haver maior efeito das tendências seculares nas mulheres. Não houve diferenças morfológicas entre homens e mulheres quando comparados intra-grupos, demonstrando que os resultados observados não foram influenciados pelo dimorfismo sexual. As diferenças de tamanho existentes intra-grupos foram responsáveis por apenas 6% das diferenças de forma, e portanto não há efeito causal do tamanho sobre as diferenças de forma observadas entre os grupos. Pode-se concluir que as diferenças morfológicas das estruturas maxilo-mandibulares encontradas neste estudo sugerem mudanças nas condições ambientais da população da Costa Central do Peru ao longo de 500 anos e podem contribuir para o melhor esclarecimento dos fatores etiológicos das más oclusões.

Esta pesquisa busca ampliar o debate sobre os movimentos sociais de luta por moradia no contexto da cidade capitalista. Embasados no conceito de direito à cidade, objetivamos analisar as espacialidades dos movimentos sociais de luta por moradia na primeira década do século XXI, na área central do Rio de Janeiro. A presença de terrenos e edifícios vazios públicos ou privados suscita questionamentos pelo fato de um município com elevado déficit habitacional possuir tantos espaços vazios. Contradições que resultam da negação do direito à cidade a todos os cidadãos. Assim, a expansão das lutas por moradia na nossa sociedade expressa o profundo agravamento da denominada: questão social. Na atual conjuntura e ao mesmo tempo, revela a capacidade de organização de segmentos da classe trabalhadora extremamente pauperizada. A partir do estudo do processo de luta protagonizada pelos moradores das ocupações: Chiquinha Gonzaga, Manoel Congo e Regente Feijó. Analisamos como essa prática social produz uma nova espacialidade na área central, da cidade do Rio de Janeiro. Essa dinâmica não indica apenas o momento de luta pela moradia, mas também como os movimentos sociais se organizam a partir desse espaço. Movimentos sociais urbanos que, no embate da vida cotidiana, produzem espaços e relações sociais alternativos ao modelo vigente de desenvolvimento geográfico desigual. A espacialidade das ocupações simboliza uma resistência e uma ação criativa ao demonstrar ao poder público que é possível transformar os espaços vazios na cidade em moradia popular, proporcionando, dessa maneira, melhora em termos de qualidade de vida dos seus moradores. O direito à cidade significa estar na cidade e vivenciá-la na sua plenitude, ou seja, fazendo uso de todas as suas benesses, participando ativamente da sua construção e reconstrução. Porém, a ação contrária dos agentes que se beneficiam da ordem vigente é imediata, e várias são as estratégias para desmobilizar os movimentos sociais. Nesse sentido, a formação de uma rede de resistência solidária dos movimentos sociais pela moradia busca: promover o fortalecimento da luta pelo direito à cidade.

This is the report from the Central Area Fisheries Advisory Committee meeting, which was held on the 8th January, 1981. It covers information on the review of fisheries byelaws, netting off Flimby beach, a large fish mortality in the River Calder and Ribble, and the review of a net limitation order which was due to expire. It also includes the stocking of Worthington Lakes, Rivington Group Reservoirs and the River Wyre, the update on the proposals for the development of angling at Stocks Reservoir and the report by the area fisheries officer on fisheries activities. This comments on river conditions and fishing for salmon, sea trout and brown trout, and migratory fish movement. Also covered in the report is an update on Middleton Hatchery, salmon cages in the River Leven, Langcliffe Hatchery and the pilot hatchery, and stocking numbers of coarse fish and non migratory trout by the Angling Associations. Finally the report adds about fish mortalities, fish disease, poaching and management work. The Fisheries Advisory Committee was part of the Regional Water Authorities, in this case the North West Water Authority. This preceded the Environment Agency which came into existence in 1996.
