A política criminal de drogas do Brasil e da Colômbia: uma análise comparativa

O objetivo deste trabalho é estudar de maneira comparada o impacto da política internacional de drogas no Brasil e na Colômbia, analisando a maneira como estes países têm adotado as diretrizes internacionais estabelecidas, adaptando-as de maneira distorcida a sua própria realidade. De igual maneira se analisa como dita política internacional, contrariando seus objetivos, tem estimulado o desenvolvimento de um mercado ilegal de drogas ilícitas na região, com o qual tem aumentado a violência e os problemas causados pela dependência a estas substâncias. Para alcançar os objetivos propostos, antes, faze-se, de maneira específica, uma breve análise da evolução da política internacional sobre drogas e, em termos gerais, da política criminal, para o qual se distingue os discursos que a compõem e o contexto social em que estes se reproduzem; em outras palavras, distinguindo a ideologia da realidade que aquela modifica. Portanto, resulta imprescindível começar qualquer estudo de política criminal sem passar por sua fonte que é o Estado. Nesse sentido, a tese central deste estudo é que de maneira similar como acontece com o Estado, a política criminal de drogas se constitui numa ideologia que cria a realidade que a sustenta, ocultando as relações de poder que há por detrás da política internacional de drogas; em outras palavras, a política internacional de drogas adotada pelo Brasil e pela Colômbia produz os males que ela pretende combater. Por último, este trabalho pretende mostrar que o debate sobre as drogas ilícitas vá além duma simples questão da ciência criminal ou o direito penal. Um debate, que parta da realidade da política criminal de drogas e de sua ideologia, leva a romper com o pensamento tradicional sustentado no saber-poder que a sustenta, e que há permitido sua acolhida no contexto tanto brasileiro como colombiano, apesar de tratar-se de realidades diferentes em quanto ao tráfico e o consumo das drogas ilícitas.

Length-based estimates of vital statistics in threadfin bream (Nemipterus japonicus) from Bay of Bengal, Bangladesh

ELEFAN 0, ELEFAN I and ELEFAN II were used to estimate vital statistics of Nemipterus japonicus from length-frequency data sampled along the coast of Bangladesh. The parameters L and K were estimated at 24.5 cm and 0.94 year super(-1). The values of M and F were found to be 1.81 and 1.58 year super(-1), respectively. The fish recruit to the fishery during May-June and September-October.

Política criminal e direito penal econômico: um estudo interdisciplinar dos crimes econômicos e tributários

Este trabalho toma como objeto o Direito Penal Econômico em perspectiva interdisciplinar, no contexto da Constituição da República e, portanto, do Estado Democrático de Direito. Os propósitos são os seguintes: Analisar os vínculos entre modelo sócio-econômico, política criminal e paradigma punitivo. Identificar perspectivas do Direito Penal Econômico, no cenário contemporâneo de sociedade de risco. Examinar pressupostos, vertentes e abordagem do Direito Penal Tributário, com enfoque na abordagem social do bem jurídico tributário, do delito fiscal, da lavagem de dinheiro, na esteira dos crimes do colarinho branco. Do ponto de vista metodológico, desenvolveu-se pesquisa descritiva, baseada no modelo crítico-dialético, apoiada no pressuposto de que a trajetória do Direito Penal e sua inserção na seara econômica e tributária acompanham as contradições e valores sócio-filosóficos dominantes na sociedade. Nesse passo, com base na doutrina, legislação e jurisprudência nacional e estrangeira, procede-se à releitura do Direito Penal Econômico, a partir da Constituição e do modelo de Estado Social, que admite a intervenção no domínio econômico, no intuito de promover a justiça social. Além disso, procede-se à análise de sistemas penais de diversos países, para verificar, no cenário da globalização econômica e da aproximação das questões relacionadas à delinquência econômica, como são enfrentados problemas relacionados à configuração, à persecução e a punição de tais delitos. A conclusão aponta para a necessidade de construção de uma Política Criminal do Direito Penal Econômico que tome em consideração variáveis relacionadas à Economia e aos Princípios do Direito Penal, de molde a promover ajustamento do sistema penal aos valores e princípios constitucionais, promovendo o equilíbrio entre interesses individuais e coletivos.

Estimating exploitable stock biomass for the Maine green sea urchin (Strongylocentrotus droebachiensis) fishery using a spatial statistics approach

The objective of this study was to investigate the spatial patterns in green sea urchin (Strongylocentrotus droebachiensis) density off the coast of Maine, using data from a fishery-independent survey program, to estimate the exploitable biomass of this species. The dependence of sea urchin variables on the environment, the lack of stationarity, and the presence of discontinuities in the study area made intrinsic geostatistics inappropriate for the study; therefore, we used triangulated irregular networks (TINs) to characterize the large-scale patterns in sea urchin density. The resulting density surfaces were modified to include only areas of the appropriate substrate type and depth zone, and were used to calculate total biomass. Exploitable biomass was estimated by using two different sea urchin density threshold values, which made different assumptions about the fishing industry. We observed considerable spatial variability on both small and large scales, including large-scale patterns in sea urchin density related to depth and fishing pressure. We conclude that the TIN method provides a reasonable spatial approach for generating biomass estimates for a fishery unsuited to geostatistics, but we suggest further studies into uncertainty estimation and the selection of threshold density values.

The U.S. Gulf of Mexico Pink Shrimp, Farfantepenaeus duorarum, Fishery: 50 Years of Commercial Catch Statistics

U.S. Gulf of Mexico, pink shrimp, Farfantepenaeus duorarum, catch statistics have been collected by NOAA’s National Marine Fisheries Service, or its predecessor agency, for over 50 years. Recent events, including hurricanes and oil spills within the ecosystem of the fishery, have shown that documentation of these catch data is of primary importance. Fishing effort for this stock has fluctuated over the 50-year period analyzed, ranging from 3,376 to 31,900 days fished, with the most recent years on record, 2008 and 2009, exhibiting declines up to 90% relative to the high levels recorded in the mid 1990’s. Our quantification of F. duorarum landings and catch rates (CPUE) indicates catch have been below the long-term average of about 12 million lb for all of the last 10 years on record. In contrast to catch and effort, catch rates have increased in recent years, with record CPUE levels measured in 2008 and 2009, of 1,340 and 1,144 lb per day fished, respectively. Our regression results revealed catch was dependent upon fishing effort (F=98.48df=1, 48, p<0.001, r2=0.67), (Catch=1,623,378 + (520) × (effort)). High CPUE’s measured indicate stocks were not in decline prior to 2009, despite the decline in catch. The decrease in catch is attributed in large part to low effort levels caused by economical and not biological or habitat related conditions. Future stock assessments using these baseline data will provide further insights and management advice concerning the Gulf of Mexic

Spatial and Temporal Distribution of Sea Turtles in the Western North Atlantic and the U.S. Gulf of Mexico from Marine Recreational Fishery Statistics Survey (MRFSS)

Systematic surveys, along with opportunistic sightings, have provided important information on sea turtle (Cheloniidae and Dermochelydae) distributions, knowledge which can help reduce the risk of harmful human interaction. In 1991 and 1992, the Marine Recreational Fishery Sta- tistics Survey (MRFSS) of the National Ma- rine Fisheries Service, NOAA, provided a unique opportunity to gain additional, synoptic information on the spatial and temporal distribution of sea turtles along the U.S. Atlantic and Gulf of Mexico coasts by asking recreational anglers if they had observed a sea turtle on their fishing trip. During the spring and summer months of those years, as water temperatures warmed, the MRFSS documented an increase in sea turtle sightings in inshore waters and in a northward direction along the U.S. Atlantic Coast and in a westward direction along the northern Gulf of Mexico. This pattern reversed in the late summer and fall months as water temperatures cooled, with sea turtles concentrating along Georgia and both coasts of Florida. Although the MRFSS did not provide species or size composition of sea turtles sighted, and effort varied depending upon location of fishing activity and time of year anglers were queried, it did provide an additional and useful means of ascertaining spatial and temporal distributions of sea turtles along these coasts.

A questão penitenciária no Rio de Janeiro: os reflexos de políticas de lei e ordem

A Prefeitura do Rio de Janeiro, por meio da Secretaria de Ordem Pública e a operação Choque de Ordem, bem como o Governo do Estado do Rio de Janeiro, atra-vés da Secretaria de Segurança Pública e do projeto UPP, demonstram que é cada vez mais constante no cotidiano carioca a adoção de políticas de lei e ordem. Em tempos de Jornada Mundial da Juventude, Copa do Mundo e Olimpíadas, controlar, vigiar, punir, neutralizar são expressões que se destacam nas políticas de segurança pública. As esta-tísticas oficiais demonstram que a adoção de políticas de lei e ordem provocaram, nos últimos cinco anos, crescimento significativo da população carcerária fluminense, com destaque para as prisões provisórias e para o elevado aumento de adolescentes apreen-didos, o que gerou sérias consequências para a execução penal e contribuiu para o au-mento do déficit de vagas do sistema penitenciário do estado do Rio de Janeiro.

The Atlantic and Gulf Menhaden Purse Seine Fisheries: Origins, Harvesting Technologies, Biostatistical Monitoring, Recent Trends in Fisheries Statistics, and Forecasting

With its genesis in New England during the 1800's, the purse seine fishery for Atlantic menhaden, Brevoortia tyrannus, expanded south and by the early 1900's ranged the length of the eastern seaboard. The purse seine fishery for Gulf menhaden. B. patronus, is of relatively recent development, exploitation of the stock beginning in the late 1940's. Landings from both fisheries annually comprise 35-40% of the total U. S. fisheries landings, ranking menhaden first in terms of volume landed. Technological advances in harvesting methods, fish-spotting capabilities, and vessel designs accelerated after World War II, resulting in larger, faster, and wider-ranging carrier vessels, improved speed and efficiency of the harvest, and reduction in labor requirements. Chief products of the menhaden industry are fish meal, fish oil, and solubles, but research into new product lines is underway. Since 1955 on the Atlantic coast and 1964 on the Gulf coast, the NMFS has monitored the fisheries for biostatistical data. Annual data summaries of numbers-of-fish-at-age harvested, catch tonnage, and fishing effort of the fleet form the basis of routine stock assessments and annual catch forecasts to industry for the upcoming fishing season. After landings declined in the 1960's, the Atlantic menhaden stock has recovered through the 1970's and 1980's. Exceptional year classes of Gulf menhaden in recent years account for record landings during the 1980's.
