Regarding canal management modernization, water savings and water delivery quality, the study presents two automatic canal control approaches of the PI (Proportional and Integral) type: the distant and the local downstream control modes. The two PI controllers are defined, tuned and tested using an hydraulic unsteady flow simulation model, particularly suitable for canal control studies. The PI control parameters are tuned using optimization tools. The simulations are done for a Portuguese prototype canal and the PI controllers are analyzed and compared considering a demand-oriented-canal operation. The paper presents and analyzes the two control modes answers for five different offtake types – gate controlled weir, gate controlled orifice, weir with or without adjustable height and automatic flow adjustable offtake. The simulation results are compared using water volumes performance indicators (considering the demanded, supplied and the effectives water volumes) and a time indicator, defined taking into account the time during which the demand discharges are effective discharges. Regarding water savings, the simulation results for the five offtake types prove that the local downstream control gives the best results (no water operational losses) and that the distant downstream control presents worse results in connection with the automatic flow adjustable offtakes. Considering the water volumes and time performance indicators, the best results are obtained for the automatic flow adjustable offtakes and the worse for the gate controlled orifices, followed by the weir with adjustable height.

As expetativas e exigências crescentes dos cidadãos face ao serviço público introduziram uma nova orientação nos processos de reforma e modernização administrativa. É neste contexto que surge o modelo de autoavaliação Common Assessment Framework (CAF), que está essencialmente direcionado para a administração pública, com o fim de promover a melhoria contínua dos serviços. Neste estudo pretende-se analisar a aplicabilidade da CAF como ferramenta de autoavaliação dos serviços públicos nos Serviços Académicos da Universidade de Évora (SAC), bem como verificar o impacto que a aplicação da CAF teve nos SAC, após o estudo realizado por Nogueira (2008), e efetuar um diagnóstico junto dos alunos, colaboradores e gestores para avaliar os processos desenvolvidos, bem como averiguar o seu grau de satisfação. Para atingir os objetivos propostos foi aplicado um inquérito por questionário junto dos alunos, colaboradores e gestores dos SAC. Os resultados obtidos permitiram extrair os pontos fortes (e.g. bons procedimentos para acolhimento e integração dos colaboradores, gestores não resistentes à mudança), evidenciar os pontos fracos (e.g. tempo de obtenção de respostas às solicitações efetuadas, atendimento telefónico desadequado), e enumerar as sugestões de melhoria para o serviço (e.g. maior número de funcionários a fazer atendimento, horários de abertura e de atendimento mais alargados); ABSTRACT: Expectations and increased demands of citizens on the public service introduced a new orientation in the reform and administrative modernization. lt is in this context that the model of self-assessment Common Assessment Framework (CAF), which is primarily directed to the government, in order to promote continuous improvement of services. This study aims to analyze the applicability of the CAF as a self-assessment tool of public services at the Academic Services of the University of Évora (SAC) and verify the impact that the implementation of the CAF had the SAC after the study by Nogueira (2008) and make a diagnosis with the students, employees and managers to assess the processes developed and ascertain their degree of satisfaction. To achieve the proposed objectives a questionnaire was applied to students, employees and managers of SAC. The results allowed to draw on the strengths (eg: good procedures for reception and integration of employees, not resistant to change managers), highlight the weaknesses (eg: time to obtain answers to made requests, inadequate telephone service), and list suggestions improvement for the service (eg: greater number of employees to service, opening hours and more extensive service).

A construção da Barragem de Alqueva foi durante anos considerada como fundamental no desenvolvimento da sustentabilidade e modernização da agricultura no Alentejo. Por outro lado a sua representação paisagística sempre se agregou a imagens de uma agricultura de sequeiro e extensiva mas hoje estamos perante uma agricultura regada e intensiva, tendo as alterações na agricultura levantado questões relativas à transformação da paisagem desta região. Na atual campanha de rega do Alqueva está previsto no sistema global de rega do projeto um total de 120 mil hectares de regadio, no entanto já existem estudos que possibilitam o aumento desta área, cerca de 45 mil hectares além do projeto inicial (EDIA, acesso em 23-2-2016) Desta forma pretende-se analisar a transformação da ocupação do solo, numa área abrangida pelo EFMA, o concelho de Beja, de modo a perceber como essa transformação ao longo do tempo tem incidido sobre a paisagem e afetado o Montado; EVOLUÇÃO DA PAISAGEM DE MONTADO NA ÁREA ABRANGIDA PELO EFMA C a s o d e E s t u d o n o C o n c e l h o d e B e j a A B S T R A C T: The construction of the Alqueva Dam was fundamental to the sustainable development and modernization of agriculture in the Alentejo. On the other hand its landscape representation has always added an image of an extensive and cutting agriculture but today we are facing a irrigated and intensive agriculture, having as changes in agriculture raised questions related to the transformation of the landscape of the region. In the current irrigation campaign of Alqueva is planned for a total of 120 thousand hectares of irrigation, there are no studies that allow the increase of the area, about 45 thousand hectares beyond the initial project (EDIA, access On 23-2-2016) In this way we intend to analyze a transformation of the land occupation, in an area covered by the EFMA, the Beja municipality, in order to understand how this transformation over time has affected a landscape and affected the Montado.

No final da década de 70 a reforma da Administração Pública surge como preocupação dos governos. No início dos anos 80 a adoção da doutrina da Nova Gestão Publica, foi um dos acontecimentos mais marcantes para a administração pública dos países da Organização para a Cooperação e Desenvolvimento Economico. A reforma na Administração Pública em Portugal iniciou-se após a rutura política e social de 1974. No início de 1986 Portugal entra para Comunidade Económica Europeia, o que representou uma maior abertura económica e um aumento na confiança interna da população, observando-se um avanço em termos de concretização de muitos direito sociais, entre outros, na educação. A modernização da administração pública na componente referente à área da educação, iniciou-se no final do ano de 1986, através da Lei de Base do Sistema Educativo, dando origem à descentralização dos serviços, introduzindo-se o conceito de autonomia. Os contratos de autonomia no meio escolar, são processos de administração que não influenciam os seus intervenientes, na realização das atividades pedagógicas, administrativas e gestionárias. Este estudo demonstra a opinião dos vários grupos que compõem um estabelecimento de ensino público Português. Na opinião da amostra deste estudo, os contratos de autonomia não são portadores de benefícios ou prejuízos para os estabelecimentos escolares, seja a nível pedagógico, a nível dos recursos humanos ou a nível administrativo e financeiro; Abstract: Contracts of autonomy in the management of grouping of schools in Portugal: An analysis based on the perception of the actors. At the end of the 70 the reform of public administration arises as a concern of governments. In the early 80s the adoption of the doctrine of the New Public Management, was one of the most important events for the public administration of the Organization for Cooperation and Economic Development countries. The reform in Public Administration in Portugal began after the political and social rupture of 1974. In the beginning of 1986 Portugal joins the European Economic Community, which represented a greater economic openness and an increase in internal confidence of the population, shown by a progress in terms of implementation of many social rights, among others, in education. The modernization of public administration in the field of education began at the end of 1986 through the Basic Law of Education, leading to the decentralization of services, introducing therefore the concept of autonomy. Autonomy contracts in schools are management processes that do not influence their stakeholders in achieving the educational, administrative and management activities. This study shows the opinion of the various groups that form an establishment of Portuguese public education. According to the sample, the autonomy contracts don’t bring benefits or losses to schools, as far as educational practices and human resources are concerned, as well as on a financial and administrative level.

O capital humano e a gestão de recursos humanos são os ativos mais valiosos de uma empresa, desse modo, compreender as necessidades e antecipá-las torna-se fundamental para o bom desempenho de uma organização. Não só a gestão, mas a aposta em investimento e educação, reciclagem profissional e modernização são fatores a definir com cuidado e precaução por parte das repartições e do comando de pessoal. Do mesmo modo, o envelhecimento, a obsolescência e deterioração são fatores que podem influenciar de forma negativa o desempenho de uma organização; The recruitment and training in the Military Forces. The Portuguese Army Abstract: This report is the conclusion of a cycle of studies in the area of management of human resources. The internship in the headquarters - Direção de Formação do Exército- and two other locations, made it clear and understandable for me to comprehend and analyze the recruitment process and military training in and outside of the Portuguese army. The human capital and the management of human recourses are the most valuable assets of a company. Understanding the needs and anticipate them becomes vital to the performance of an organization. Not only the management, but also the investment in education, retraining and modernization, are key factors that should be defined with care and precaution by the divisions in command of the staff. At the same time, the obsolescence, aging, and deterioration can be negative factors to the organization.

The process of modernization of Brazilian agriculture aimed at increasing the productivity in response to the high demand for agricultural products in the world market and it was based on the intensive use of inputs such as agrochemicals, intense mechanisation and breeding of new varieties. Among these, pesticides were incorporated in almost all production systems. Over reliance on pesticide use has produced many negative effects on both biotic and abiotic components of the environment, generating chemical contamination of soil and water, decrease in biological diversity of agroecosystems, disruption of natural cycles, pest resistance, intoxication of growers, among others. The consumption of pesticides in Brazil was 151.8 thousand tonnes in 1989, and today the country is the fifth world market of these products. The use of pesticides increased from 16 thousand tonnes (a.i.) in 1964 to 60.2 thousand tonnes in 1991, while the area planted to crops grew from 28.4 to 50.0 million ha in the same period. This means an increase of 276.2% in consumption of pesticides compared to an increase of 76% in planted area. Even with this large increase in the use of pesticides, the losses caused by pests have not been significantly reduced, and the net gain in crop productivity has been low. On the other hand, problems with food contamination, environmental degradation of growers have considerably mounted. It is possible to define two classes of crops regarding intense use of pesticides. One is represented by those crops that occupy large areas, and therefore contribute to a large amont of pesticides used for pest control in a country basis. The other class comprises crops that require large amounts of pesticides per unit of area, but not necessarily represent large amounts of pesticides used coutry-wide. Based on the classes proposed, citrus, soybean and sugarcane stand as crops with a nationally great consumption of pesticides, while tomato, potato and citrus are important as intensive users of pesticides. In this paper the biotechnologies in use, the biotechnologies in advanced stages of development, the main constraints to the development and use of biotechnlology and the impact of pesticed on the environment are discussed.
