Sustainable management of coastal sand dunes to human activities and natural disasters in Oregon, the United States
Dune destabilization became a socio-economic issue as Euro-Americans settled in Oregon in the 19th century. Non-native Ammophila arenaria and Ammophila breviligulata were widely used for stabilization from the early-20th century. As non-native beachgrasses turned invasive causing the loss of biodiversity and habitats, their removal became the focus to regain the active dunes to support the natural processes of the ecosystem. In this work we aimed to understand the response of coastal sand dunes to natural hazards (e.g. sea-level rise), human activities (e.g. settlement, urbanization and animal husbandry) and dune management initiatives (e.g. planting of non-native beachgrasses) in Oregon in the United States during two contrasting periods: 1) from the 19th to late-20th century and 2) from there to the early-21st century.info:eu-repo/semantics/publishedVersio
Does e-learning policy drive change in Higher Education?: A case study relating models of organisational change to e-learning implementation
Due to the heightened competition introduced by the potential global market and the need for structural changes within organisations delivering e-content, e-learning policy is beginning to take on a more significant role within the context of educational policy per se. For this reason, it is becoming increasingly important to establish what effect such policies have and how they are achieved. This paper addresses this question, illustrating five ways in which change is understood (Fordist, evolutionary, ecological, community of practice and discourse-oriented) and then using this range of perspectives to explore how e-learning policy drives change (both organisational and pedagogic) within a selected higher education institution. The implications of this case are then discussed, and both methodological and pragmatic conclusions are drawn, considering the relative insights offered by the models and ways in which change around e-learning might be supported or promoted

Método do índice de qualidade na determinação do frescor de peixes.
O Método do Índice de Qualidade é um sistema de controle de qualidade do frescor do pescado e baseia-se na avaliação objetiva dos principais atributos sensoriais de cada espécie de peixe, através de um sistema de pontos de demérito. O MIQ é baseado na avaliação visual e olfativa de certos atributos do peixe, principalmente a aparência dos olhos, pele e brânquias, juntamente com o odor e textura, através de um sistema de classificação por pontos de demérito, de 0 a 3. A pontuação de todos os atributos é somada para dar uma pontuação global sensorial, o chamado Índice de Qualidade (IQ). O método permite a avaliação da qualidade do pescado em questão, a previsão da validade comercial da espécie estudada, com a vantagem de ser barato, simples, requerer pouco treinamento em relação aos outros métodos e não destruir a amostra. Sua aplicação faz da análise sensorial, tão importante para avaliação do frescor do pescado, um método objetivo, permitindo de forma confiável e rápida, a avaliação da matéria-prima, seja a bordo das embarcações, no controle da matéria-prima nas indústrias, ou nos entrepostos e em postos de venda
