Non perennial Mediterranean Rivers in Europe: Status, pressurs, and challanges for research and management

Non-perennial rivers and streams (NPRS) cover >50% of the global river network. They are particularly predominant in Mediterranean Europe as a result of dry climate conditions, climate change and land use development. Historically, both scientists and policy makers underestimated the importance of NRPS for nature and humans alike, mainly because they have been considered as systems of low ecological and economic value. During the past decades, diminishing water resources have increased the spatial and temporal extent of artificial NPRS as well as their exposure to multiple stressors, which threatening their ecological integrity, biodiversity and ecosystem services. In this paper, we provide a comprehensive overview of the structural and functional characteristics of NPRS in the European Mediterranean, and discuss gaps and problems in their management, concerning their typology, ecological assessment, legislative and policy protection, and incorporation in River Basin Management Plans. Because NPRS comprise highly unstable ecosystems, with strong and often unpredictable temporal and spatial variability - at least as far as it is possible to assess - we outline the future research needs required to better understand, manage and conserve them as highly valuable and sensitive ecosystems. Efficient collaborative activities among multidisciplinary research groups aiming to create innovative knowledge, water managers and policy makers are urgently needed in order to establish an appropriate methodological and legislative background. The incorporation of NPRS in EU-Med River Basin Management Plans in combination with the application of ecological flows is a first step towards enhancing NPRS management and conservation in order to effectively safeguard these highly valuable albeit threatened ecosystems

A influência da cultura organizacional nas actividades pedagógicas dos professores do ensino superior: um estudo de caso

Com o presente estudo pretende-se compreender a importância da cultura organizacional escolar e demonstrar a sua influência nas actividades pedagógicas dos docentes. Na abordagem teórica referem-se algumas definições, principais características, funções e importância da cultura, cultura organizacional e cultura organizacional escolar, com base na bibliografia consultada. Faz-se referência a modelos de análise da cultura organizacional e refere-se a sua importância face às mudanças nas organizações. Este estudo configura-se como um estudo de caso, utiliza-se uma amostra de três docentes do Curso de Licenciatura em Radioterapia da Escola Superior de Tecnologia da Saúde de Lisboa. Na recolha de dados efectua-se a cada docente, três entrevistas semi-estruturadas, designadas de Entrevista, Entrevista Reflexiva e Entrevista Reflexiva Aprofundada. Analisam-se os dados através da análise de conteúdo, seleccionando-se categorias analíticas relevantes para o estudo. Nas considerações finais aborda-se a importância da cultura escolar nas actividades pedagógicas dos docentes e sugerem-se novas linhas de estudo. ABSTRACT: With the present study it's intend to understand the importance of the scholar organizational culture and demonstrate its influence on the teacher's pedagogic activities. ln the theoretical part there are mentioned some definitions, main characteristics, functions and importance of culture, organizational culture and scholar organizational culture, based on the consulted bibliography. Are mentioned also models of analysis of the organizational culture and their importance on the organizational changes. This study is a case study; it's used a sample of three teachers of the Radiotherapy Degree of the Higher School of Health Technologies of Lisbon. There were made three semi­ structured interviews to each teacher, called Interview, Reflexive lnterview and Deepened Reflexive Interview. The data were analysed through content analysis, by selecting analytic categories relevant to the study. ln the final considerations is approached the importance of the scholar culture in the pedagogic activities of teachers and are suggested new study lines.
