Multi-criteria group decision support with linguistic variables in long-term scenarios for Belgian energy policy

Real world decisions often made in the presence of multiple, conflicting, and incommensurate criteria. Decision making requires multiple perspectives of different individuals as more decisions are made now in groups than ever before. This is particularly true when the decision environment becomes more complex such as sustainability policies study in environmental and energy sectors. Group decision making processes judgments or solutions for decision problems based on the input and feedback of multiple individuals. Multi-criteria decision and evaluation problems at tactical and strategic levels in practice involve fuzziness in terms of linguistic variables vis-à-vis criteria, weights, and decision maker judgments. Relevant alternatives or scenarios are evaluated according to a number of desired criteria. A fuzzy multi-criteria group decision software tool is developed to analyze long-term scenarios for Belgian energy policy in this paper

Maturação biológica: da sua relevância à aprendizagem do método TW3

Este estudo teve os seguintes objetivos: (1) apresentar procedimentos metodológicos utilizados na estimação da idade óssea; (2) descrever o método Tanner-Whitehouse (TW3), e (3) destacar os resultados da reprodutibilidade deste método em crianças e jovens. A metodologia adotada na preparação do processo de aprendizagem e reprodutibilidade do método TW3 foi estruturada em três fases, tendo sido realizadas em duas Instituições de ensino (Portugal e Bélgica), sob a orientação e supervisão de avaliadores experientes. Após várias etapas de treinamento, os resultados alcançados na avaliação inter e intraobservador situaram-se entre 81,3 e 87,9%. Os resultados finais do estudo possibilitaram comprovar a eficácia de um rigoroso processo de treino, como elemento essencial na preparação prévia do avaliador, para a utilização da avaliação da maturação esquelética com base no método TW3

Effectiveness of the global protected area network in representing species diversity

The Fifth World Parks Congress in Durban, South Africa, announced in September 2003 that the global network of protected areas now covers 11.5% of the planet's land surface. This surpasses the 10% target proposed a decade earlier, at the Caracas Congress, for 9 out of 14 major terrestrial biomes. Such uniform targets based on percentage of area have become deeply embedded into national and international conservation planning. Although politically expedient, the scientific basis and conservation value of these targets have been questioned. In practice, however, little is known of how to set appropriate targets, or of the extent to which the current global protected area network fulfils its goal of protecting biodiversity. Here, we combine five global data sets on the distribution of species and protected areas to provide the first global gap analysis assessing the effectiveness of protected areas in representing species diversity. We show that the global network is far from complete, and demonstrate the inadequacy of uniform—that is, 'one size fits all'—conservation targets

Towards the understanding of the cocoa transcriptome: Production and analysis of an exhaustive dataset of ESTs of Theobroma cacao L. generated from various tissues and under various conditions

Theobroma cacao L., is a tree originated from the tropical rainforest of South America. It is one of the major cash crops for many tropical countries. T. cacao is mainly produced on smallholdings, providing resources for 14 million farmers. Disease resistance and T. cacao quality improvement are two important challenges for all actors of cocoa and chocolate production. T. cacao is seriously affected by pests and fungal diseases, responsible for more than 40% yield losses and quality improvement, nutritional and organoleptic, is also important for consumers. An international collaboration was formed to develop an EST genomic resource database for cacao. Fifty-six cDNA libraries were constructed from different organs, different genotypes and different environmental conditions. A total of 149,650 valid EST sequences were generated corresponding to 48,594 unigenes, 12,692 contigs and 35,902 singletons. A total of 29,849 unigenes shared significant homology with public sequences from other species. Gene Ontology (GO) annotation was applied to distribute the ESTs among the main GO categories. A specific information system (ESTtik) was constructed to process, store and manage this EST collection allowing the user to query a database. To check the representativeness of our EST collection, we looked for the genes known to be involved in two different metabolic pathways extensively studied in other plant species and important for T. cacao qualities: the flavonoid and the terpene pathways. Most of the enzymes described in other crops for these two metabolic pathways were found in our EST collection. A large collection of new genetic markers was provided by this ESTs collection. This EST collection displays a good representation of the T. cacao transcriptome, suitable for analysis of biochemical pathways based on oligonucleotide microarrays derived from these ESTs. It will provide numerous genetic markers that will allow the construction of a high density gene map of T. cacao. This EST collection represents a unique and important molecular resource for T. cacao study and improvement, facilitating the discovery of candidate genes for important T. cacao trait variation.

Clarifying misconceptions of extinction risk assessment with the IUCN Red List

This is the author accepted manuscript. The final version is available from the publisher via the DOI in this record.The identification of species at risk of extinction is a central goal of conservation. As the use of data compiled for IUCN Red List assessments expands, a number of misconceptions regarding the purpose, application and use of the IUCN Red List categories and criteria have arisen. We outline five such classes of misconception; the most consequential drive proposals for adapted versions of the criteria, rendering assessments among species incomparable. A key challenge for the future will be to recognize the point where understanding has developed so markedly that it is time for the next generation of the Red List criteria. We do not believe we are there yet but, recognizing the need for scrutiny and continued development of Red Listing, conclude by suggesting areas where additional research could be valuable in improving the understanding of extinction risk among species

Management of chemical residues in universities: assessing the University of Brasília

The University of Brasília (UnB) uses a diversity of chemical products, generating residues in a significant way in its multiple activities – teaching, research and community services. The UnB Comission on Chemical Residues Management was established in November 2002, aiming at three main objectives: 1) correct destination for the accumulated residues; 2) implantation of a chemical residues management system and 3) implantation of a UnB Unit for Treatment of Chemical Residues. To fulfil these commitments, a diagnosis of chemical residues produced by the University was performed, which is here presented with an evaluation of their future use, limitations and possibilities
