Addressing complexity and uncertainty: conceptual models and expert judgments applied to migratory birds in the oil sands of Canada Ecology and Society

Complexity and uncertainty are inherent in social-ecological systems. Although they can create challenges for scientists and decision makers, they cannot be a reason for delaying decision making. Two strategies have matured in recent decades to address these challenges. Systems thinking, as embodied by conceptual modeling, is a holistic approach in which a system can be better understood by examining it as a whole. Expert elicitation represents a second strategy that enables a greater diversity of inputs to understand complex systems. We explored the use of conceptual models and expert judgments to inform expansion of monitoring around oil sands development in northern Alberta, Canada, particularly related to migratory forest birds. This study area is a...

Aplicação de reengenharia de tesauro: modelagem do THESAGRO. Repositório Alice
MACULAN, B. C. M. S.; LIMA, G. A. B. O.; PIEROZZI JUNIOR, I.; OLIVEIRA, L. H. M..
Este estudo investigou e aplicou um modelo de reengenharia de tesauros tradicionais para tornar o sistema de relações entre os conceitos em uma estrutura semântica rica. O modelo selecionado para a aplicação foi desenvolvido por Soergel et al. (2004) e Lauser et al. (2006). Esse modelo é composto por três etapas e envolve a melhoria e explicitação formal das relações semânticas em um tesauro. A reengenharia foi aplicada no tesauro brasileiro THESAGRO, do domínio da Agricultura, no recorte temático da Intensificação Agropecuária. A metodologia incluiu o uso das ferramentas: (a) Sistema e-Termos, para o gerenciamento da terminologia; e (b) Extrator de Termos, software que permite a comparação automática da terminologia de diferentes tesauros. Os resultados...

Many river restoration projects fail. Inadequate project planning underpins many of the reasons given for failure (such as setting overly ambitious goals; selecting inappropriate sites and techniques; losing stakeholder motivation; and neglecting to monitor, assess, and document projects). Another major problem is the lack of an agreed guiding image to direct the activities aimed at restoring the necessary biophysical and ecological processes within the logistic constraints of on-ground works. Despite a rich literature defining the components of restoration project planning, restoration ecology currently lacks an explicit and logical means of moving from the initial project vision through to on-ground strategies. Yet this process is fundamental because it...
