A construção da identidade profissional é um processo de aprendizagem constante que se encontra intimamente relacionado com o gosto, a vontade de crescer e evoluir continuamente, tanto a nível profissional, como pessoal. De facto, ser professor com sentido é um enorme desafio que ganha significado em contexto educativo. Nesse momento, torna-se possível refletir sobre as diversas dimensões implicadas no perfil de um (bom) professor. É neste quadro que a elaboração do presente relatório de estágio é extremamente significativa, na medida em que se desenvolve progressivamente, ao longo de um ano bastante exigente, embora riquíssimo em experiências e partilhas de ideias. A sua realização surge no âmbito da unidade curricular Integração Curricular: Prática Educativa e Relatório de Estágio, inserida no segundo ano do mestrado em Ensino do 1.º e 2.º Ciclos do Ensino Básico. É de salientar o papel preponderante dos professores orientadores cooperantes, dos supervisores institucionais e do par pedagógico, ao longo desta jornada. O espírito de cooperação vivido durante este processo evolutivo permitiu que a professora estagiária apurasse o seu caráter reflexivo e colaborativo. O estado de comprometimento assumido com o contexto educativo transformou-se numa experiência verdadeiramente inesquecível para a formanda. Repare-se que o presente trabalho apresenta um cariz investigativo no âmbito da exploração de um projeto onde a Transdisciplinaridade é abordada como um fator relevante para a formação de seres críticos, ativos e reflexivos. Com a Prática Pedagógica Supervisionada e o pleno envolvimento com o agrupamento de escolas X, foi possível traçar um mapa para a descoberta de um tesouro, isto é, para a construção de um perfil de docente que assegurará – assim se espera - uma viagem profunda, profícua e enriquecedora.

The growing importance and influence of new resources connected to the power systems has caused many changes in their operation. Environmental policies and several well know advantages have been made renewable based energy resources largely disseminated. These resources, including Distributed Generation (DG), are being connected to lower voltage levels where Demand Response (DR) must be considered too. These changes increase the complexity of the system operation due to both new operational constraints and amounts of data to be processed. Virtual Power Players (VPP) are entities able to manage these resources. Addressing these issues, this paper proposes a methodology to support VPP actions when these act as a Curtailment Service Provider (CSP) that provides DR capacity to a DR program declared by the Independent System Operator (ISO) or by the VPP itself. The amount of DR capacity that the CSP can assure is determined using data mining techniques applied to a database which is obtained for a large set of operation scenarios. The paper includes a case study based on 27,000 scenarios considering a diversity of distributed resources in a 33 bus distribution network.

Purpose: To describe and compare the content of instruments that assess environmental factors using the International Classification of Functioning, Disability and Health (ICF). Methods: A systematic search of PubMed, CINAHL and PEDro databases was conducted using a pre-determined search strategy. The identified instruments were screened independently by two investigators, and meaningful concepts were linked to the most precise ICF category according to published linking rules. Results: Six instruments were included, containing 526 meaningful concepts. Instruments had between 20% and 98% of items linked to categories in Chapter 1. The highest percentage of items from one instrument linked to categories in Chapters 2–5 varied between 9% and 50%. The presence or absence of environmental factors in a specific context is assessed in 3 instruments, while the other 3 assess the intensity of the impact of environmental factors. Discussion: Instruments differ in their content, type of assessment, and have several items linked to the same ICF category. Most instruments primarily assess products and technology (Chapter 1), highlighting the need to deepen the discussion on the theory that supports the measurement of environmental factors. This discussion should be thorough and lead to the development of methodologies and new tools that capture the underlying concepts of the ICF.

In the last few years the number of systems and devices that use voice based interaction has grown significantly. For a continued use of these systems the interface must be reliable and pleasant in order to provide an optimal user experience. However there are currently very few studies that try to evaluate how good is a voice when the application is a speech based interface. In this paper we present a new automatic voice pleasantness classification system based on prosodic and acoustic patterns of voice preference. Our study is based on a multi-language database composed by female voices. In the objective performance evaluation the system achieved a 7.3% error rate.
