| Multi-biomarker approaches are used to assess ecosystem health and identify impacts of environmental stress on organisms. However, exploration of large datasets by environmental managers represents a major challenge for regulatory application of this tool. Several integrative tools were developed to summarize biomarker responses. The aim of the present paper is to update calculation of the "Integrated Biological Response" (IBR) described by Beliaeff and Burgeot (Environ Toxicol Chem 21:1316-1322, 2002) to avoid weaknesses of this integrative tool. In the present paper, a novel index named "Integrated Biological Responses version 2" based on the reference deviation concept is presented. It allows a clear discrimination of sampling sites as for the IBR, but... |

| Para que o produtor se adapte aos novos moldes de produção, um intenso controle sobre os dados do rebanho deve ser empregado nos sistemas de produção de leite. Além de produzir com eficiência, sustentabilidade ambiental, responsabilidade social e sem desperdícios é preciso desenvolver habilidades no gerenciamento e motivação de pessoas para comprar insumos, na venda da produção e na gestão adequada dos custos. Desta forma, há necessidade que o produtor desenvolva ferramentas e práticas de monitoramento de seus dados para processar, interpretar e transformá–los em informação. Vários fatores afetam o registro e gestão dos dados da fazenda. O efetivo uso de registros representa um “divisor de águas” na medicina moderna do gado de leite. A coleta de dados... |

| The present study compares the performance of stochastic and fuzzy models for the analysis of the relationship between clinical signs and diagnosis. Data obtained for 153 children concerning diagnosis (pneumonia, other non-pneumonia diseases, absence of disease) and seven clinical signs were divided into two samples, one for analysis and other for validation. The former was used to derive relations by multi-discriminant analysis (MDA) and by fuzzy max-min compositions (fuzzy), and the latter was used to assess the predictions drawn from each type of relation. MDA and fuzzy were closely similar in terms of prediction, with correct allocation of 75.7 to 78.3% of patients in the validation sample, and displaying only a single instance of disagreement: a... |

| The main body of the Workshop was devoted to fromal presentations, discussions and hands-on training in sea-level measurements and analysis. In addition, two days of field excursions were undertaken, and a programme of social events took place; The detail of the Workshop Programme can be found in Annex I, whilst a list of course facilities and reference materials can be found in Annex III |
