O viva Rio e a construção de uma cultura da paz: cidadania, violência e paz na campanha do desarmamento de 2004

Na campanha do desarmamento organizada pela Organização Não Governamental Viva Rio - e realizada entre meados de 2004 e outubro de 2005, com o Referendo Sobre a Proibição do Comércio de Armas de Fogo no Brasil , os atores, discursos e práticas envolvidos na causa do desarmamento se voltavam, majoritariamente, a uma estratégia de apelo aos corações aos cidadãos de bem como forma de persuasão, atrelavam, de modo amplo, a defesa ao desarmamento à defesa à paz e ao combate à violência, e se concentravam, principalmente, na divulgação e promoção da campanha de entrega das armas. Para o debate em torno do Estatuto do Desarmamento e do Referendo, entretanto, novos atores entraram na disputa e começaram a ganhar visibilidade na esfera pública. Os atores engajados pelo "não" no Referendo acionaram aliados e seus discursos em prol de sua causa, recorrendo a elementos da moral e da religião na defesa da posse de armas como um direito inalienável dos cidadãos.Este trabalho reflete sobre as ações engendradas pelo Viva Rio em torno da questão do desarmamento desde sua fundação - com destaque para a Campanha do Desarmamento de 2004 -, discutindo a presença da religiosidade em suas iniciativas e a contribuição desta na constituição de noções de paz, violência e cidadania no espaço público brasileiro. Examina, ainda, de que modo estas noções fundamentaram a atuação pública do Viva Rio na construção de uma cultura da paz e ajudaram a compor um campo de parcerias e disputas no cenário nacional.

Skimmer Trawl Fishery Catch Evaluations in Coastal Louisiana, 2004 and 2005

Fishery observers collected data from 307 tows during 96 trips aboard skimmer trawl vessels in Louisiana’s coastal waters from September 2004 through June 2005 to estimate catch rates of target and nontarget species, including sea turtles (Cheloniidae and Dermochelyidae), by area and season during commercial shrimping operations. About 16,965.7 kg of total catch were recorded during 517.0 hours of fishing operations. Based on weight extrapolations from species composition samples, penaeid shrimp (Penaeidae) dominated the catch at 66%, followed by finfish at 19%, nonpenaeid shrimp crustaceans at 7%, discarded penaeid shrimp at 6%, and debris at 3%. Noncrustacean invertebrates comprised less than 1%. Catch rates in kilograms per hour by category was 21.6 for penaeid shrimp, 6.2 for finfish, 2.2 for nonpenaeid crustaceans, 1.8 for discarded penaeid shrimp, and 0.9 for debris. White shrimp, Litopenaeus setiferus, other penaeid shrimp, and Gulf menhaden, Brevoortia patronus, were the top three dominant species by weight. Seasonally, a higher catch rate was observed from May through August 2005 for penaeid shrimp as compared with the September through December 2004 period. Conversely, the September through December 2004 period experienced a higher catch rate for finfish than during May through August 2005. No sea turtle interactions were documented.

Linking elements of the Integrated Ocean Observing System (IOOS) with the planned National Water Quality Monitoring Network. Proceedings from the NOAA-Supported workshop 19-21 September 2005

The National Oceanic and Atmospheric Administration (NOAA), in cooperation with the New Jersey Marine Sciences Consortium (NJMSC), hosted a workshop at Rutgers University on 19-21 September 2005 to explore ways to link the U.S. Integrated Ocean Observing System (IOOS) to the emerging infrastructure of the National Water Quality Monitoring Network (NWQMN). Participating partners included the Mid-Atlantic Coastal Ocean Observing Regional Association, U.S. Geological Survey, Rutgers University Coastal Ocean Observing Laboratory, and the New Jersey Sea Grant College. The workshop was designed to highlight the importance of ecological and human health linkages in the movement of materials, nutrients, organisms and contaminants along the Delaware Bay watershed-estuary-coastal waters gradient (hereinafter, the “Delaware Bay Ecosystem [DBE]”), and to address specific water quality issues in the mid-Atlantic region, especially the area comprising the Delaware River drainage and near-shore waters. Attendees included federal, state and municipal officials, coastal managers, members of academic and research institutions, and industry representatives. The primary goal of the effort was to identify key management issues and related scientific questions that could be addressed by a comprehensive IOOS-NWQMN infrastructure (US Commission on Ocean Policy 2004; U.S. Ocean Action Plan 2004). At a minimum, cooperative efforts among the three federal agencies (NOAA, USGS and EPA) involved in water quality monitoring were required. Further and recommended by the U.S. Commission on Ocean Policy, outreach to states, regional organizations, and tribes was necessary to develop an efficient system of data gathering, quality assurance and quality control protocols, product development, and information dissemination.

Enhancing pnemonia surveillance in acute care facilities in post SARS era : a Canadian hospital surveillance study, 2003-2004 influenza season

A retrospective study of patients hospitalized with influenza and/or pneumonia in a Niagara area community hospital for the influenza season 2003-04 was designed with the main goal of enhancing pneumonia surveillance in acute care facilities and the following specific objectives: 1) identify etiologies, factors, and clinical presentation associated with pneumonia; 2) assess the ODIN score on ICU patients to predict outcomes of severe pneumonia; 3) identify the frequency of pneumonia and influenza in a hospital setting; and 4) develop a hospital pneumonia electronic surveillance tool. A total of 172 patients' charts (50% females) were reviewed and classified into two groups: those with diagnosis of pneumonia (n=132) and those without pneumonia (n=40). The latter group consisted mainly of patients with influenza (85%). Most patients were young (<10yrs) or elderly (>71yrs). Presenting body temperature <38°C, cough symptoms, respiratory and cardiac precomorbidities were common in both groups. Pneumonia was more frequent in males (p= .032) and more likely community-acquired (98%) than nosocomial (2%). No evidence of ventilator-associated pneumonia was found. Microbiology testing in 72% of cases detected 19 different pathogens. In pneumonia patients the most common organisms were Streptococcus pneumoniae (3%), Respiratory syncytial virus (4%), and Influenza A virus (2%). Conversely, Influenza A virus was identified in 73% of non-pneumonia patients. Community-acquired influenza was more common (80%) than nosocomial influenza (20%). The ODIN score was a good predictor of mortality and the new electronic surveillance tool was an effective prototype to monitor patients in acute care, especially during influenza season. The results of this study provided baseline data on respiratory illness surveillance and demonstrated that future research, including prospective studies, is warranted in acute care facilities.
