A total of 442 anglers in a coastal region of SE Brazil were interviewed to obtain information about recreational fishing. The anglers were mature individuals (mean age ≈43 years) with a high level of education. However, many did not have a fishing licence. Target fishes belonged to 47 species. Mean catch (Catch per unit effort ‐ CPUE) was 4.2 fish−1 day−1 or 488 g−1 angler−1 day−1. Total estimated catch in the study period was equivalent to 2% of commercial landings, indicating that recreational fishing has little impact on fish stocks. The anglers complained that fishing conditions had worsened because of environmental degradation. Catch‐and‐release was classified as a ‘good’ attitude despite reports of practices that caused suffering to fish. However, when asked about prohibition of catch‐and‐release, which is enforced in some countries, the anglers said they would not accept such a prohibition if proposed by Brazilian fishing authorities. As a general rule, issues related to animal welfare and animal rights are not discussed widely by society or by fishing authorities in Brazil. Suggestions for integrated management of coastal resources and for monitoring recreational fishing are presented.

Paraconsistent logic (PL) is a type of non-classical logic that accepts contradiction as a fundamental concept and has produced valuable results in the analysis of uncertainties. In this work, algorithms based on a type of PL-paraconsistent annotated logic of two values (PAL2v)-are interconnected into a network of paraconsistent analysis (PANnet). PANnet was applied to a dataset comprising 146 Raman spectra of skin tissue biopsy fragments of which 30 spectra were determined to represent normal skin tissue (N), 96 were determined to represent tissue with basal cell carcinoma, and 19 were determined to be tissue with melanoma (MEL). In this database, paraconsistent analysis was able to correctly discriminate 136 out of a total of 145 fragments, obtaining a 93.793 % correct diagnostic accuracy. The application of PAL2v in the analysis of Raman spectroscopy signals produces better discrimination of cells than conventional statistical processes and presents a good graphical overview through its associated lattice structure. The technique of PAL2v-based data processing can be fundamental in the development of a computational tool dedicated to support the diagnosis of skin cancer using Raman spectroscopy.

RESUMOOs temas ambientais e de conservação dos recursos naturais, de aquecimento global, de economia de energia e de sustentabilidade vêm sendo alvo de interesse de organizações, principalmente as relacionadas à tecnologia da informação (TI), uma vez que resíduos de equipamentos eletrônicos podem impactar seriamente o meio ambiente. Práticas são adotadas por várias empresas e este estudo aborda uma delas, do ramo de educação, para analisar suas ações, estratégias, meios de conscientização junto aos clientes e à sociedade, práticas de TI verde utilizadas para que haja sustentabilidade e sirva como referência às empresas do mesmo ramo de atuação. O levantamento de informações foi feito por meio de pesquisas de opinião realizadas com colaboradores que atuam em áreas de TI, compra de materiais e manutenção de infraestrutura da organização, que informaram quantidades de equipamentos e peças descartadas pela instituição e práticas de TI verde que estão procurando adotar. Esses colaboradores atuam como influenciadores dos gestores para tornar a tomada de decisão no gerenciamento de seus ecossistemas tecnológicos o menos impactante possível ao meio ambiente. Os resultados obtidos na análise, quantificação e classificação das peças (cartuchos de tinta, tonner e monitores CTR -Catodic Ray Tube -tubo de raios catódicos) foram relevantes para os gestores da empresa que não conheciam a dimensão da quantidade de lixo eletrônico descartado anualmente. Dessa forma, poderão posteriormente relacionar os elementos químicos predominantes em cada um deles que pode causar impacto ambiental, o que pode servir de modelo para empresas afins.Palavras-chave: TI verde, problemas ambientais, sustentabilidade, ecossistemas tecnológicos.
