Proposta de Produção de Unidade Didática para Manual de Português Comercial

Num cenário de crescente mobilidade social, cultural e linguística, urge cada vez mais dotar os aprendentes de línguas estrangeiras de competências linguísticas alargadas e, nomeadamente, de competências comunicativas especializadas. Em parte devido à relevância do Brasil no cenário económico mundial, a Língua Portuguesa tem vindo a ganhar importância enquanto língua de transação económica. Assim, a escolha do Português Comercial como tema de trabalho resulta não só da tomada de consciência de novas realidades, mas igualmente da verificação da quase total inexistência de material didático de suporte ao processo ensino-aprendizagem de Português LE, em contexto formal ou informal, de relações comerciais e de negócios.

Enterprise reference lexicon building from business models

Nowadays, a significant increase on the demand for interoperable systems for exchanging data in business collaborative environments has been noticed. Consequently, cooperation agreements between each of the involved enterprises have been brought to light. However, due to the fact that even in a same community or domain, there is a big variety of knowledge representation not semantically coincident, which embodies the existence of interoperability problems in the enterprises information systems that need to be addressed. Moreover, in relation to this, most organizations face other problems about their information systems, as: 1) domain knowledge not being easily accessible by all the stakeholders (even intra-enterprise); 2) domain knowledge not being represented in a standard format; 3) and even if it is available in a standard format, it is not supported by semantic annotations or described using a common and understandable lexicon. This dissertation proposes an approach for the establishment of an enterprise reference lexicon from business models. It addresses the automation in the information models mapping for the reference lexicon construction. It aggregates a formal and conceptual representation of the business domain, with a clear definition of the used lexicon to facilitate an overall understanding by all the involved stakeholders, including non-IT personnel.

A GNR e a cooperação entre órgãos da polícia criminal na sociedade do risco. Estudo de caso:

Cooperation between police forces is a topic that is increasingly relevant. The emergence of new threats, as well as looking for new ways to fight crime, require from the, careful monitoring and strict sharing of all relevant information. This Work is entitled “The GNR and cooperation between Criminal Police Bodies in the Risk Society. Case Study: District of Lisbon” and aims to study the cooperation and coordination between police forces in Lisbon district, and verify if there is an parallel between the rule of law and the police procedures. The work is organized in four chapters. The first consists in a theoretical framework to perceive the context and objectives of this work. The second addresses the role of the, the different types of cooperation and instruments that promote cooperation between them. The third presents and analyzes the results. Finally, the fourth and last chapter the conclusions are woven answered the questions derived and starting question, tested hypotheses, and those limitations and future recommendations. In conclusion, the District of Lisbon, there is cooperation, materialized in a constant exchange of information, based on personal and informal relationship between the elements of the various Police Forces.

Sustained competitive advantage of different sized multinational corporations in rural base of the pyramid markets

This thesis explores how multinational corporations of different sizes create barriers to imitation and therefore sustain competitive advantage in rural and informal Base of the Pyramid economies. These markets require close cooperation with local partners in a dynamic environment that lacks imposable property rights and follows a different rationale than developed markets. In order to explore how competitive advantage is sustained by different sized multinational corporations at the Base of the Pyramid, the natural-resource-based view and the dynamic capabilities perspective are integrated. Based on this integration the natural-resource-based view is extended by identifying critical dynamic capabilities that are assumed to be sources of competitive advantage at the Base of the Pyramid. Further, a contrasting case study explores how the identified dynamic capabilities are protected and their competitive advantage is sustained by isolating mechanisms that create barriers to imitation for a small to medium sized and a large multinational corporation. The case study results give grounds to assume that most resource-based isolating mechanisms create barriers to imitation that are fairly high for large and established multinational corporations that operate at the rural Base of the Pyramid and have a high product and business model complexity. On the contrary, barriers to imitation were found to be lower for young and small to medium sized multinational corporations with low product and business model complexity that according to some authors represent the majority of rural Base of the Pyramid companies. Particularly for small to medium sized multinational corporations the case study finds a relationship- and transaction-based unwillingness of local partners to act opportunistically rather than a resource-based inability to imitate. By offering an explanation of sustained competitive advantage for small to medium sized multinational corporations at the rural Base of the Pyramid this thesis closes an important research gap and recommends to include institutional and transaction-based research perspectives.

Os sentidos da performatividade escolar fora dos muros da escola

Na última década, a pressão exercida sobre a escola pública para a produção de resultados tornouse uma constante da agenda política, arrastando consigo alterações significativas na reconfiguração organizacional e nas dinâmicas de escolarização. Reféns de múltiplos mecanismos de prestação de contas, alguns deles introduzidos de forma camuflada, as escolas e os agrupamentos de escolas veem-se coagidos a adotar lógicas performativas e competitivas, alterando por vezes o sentido original da sua missão estratégica. Este movimento de natureza tentacular está a invadir os mais diversos recantos da organização escolar, impondo outras agendas e racionalidades ao nível da sua gestão política, pedagógica e cultural. Esta comunicação pretende explorar o efeito que este fenómeno tem vindo a operar na relação entre os processos escolares e não-escolares e na forma como estes têm vindo a alterar as suas fronteiras. Tomando como objeto de estudo as trajetórias de excelência dos alunos de uma escola secundária, discutese a importância dos contextos não-escolares e das experiências não-formais e informais na construção de percursos de elevado desempenho académico. Por um lado, analisa-se o modo como a escola interseta as suas políticas de gestão organizacional e pedagógica com as lógicas que imperam na esfera não-escolar e que podem interferir com a produção dos resultados académicos; por outro lado, procura-se indagar as influências dos processos de aprendizagem e avaliação formal sobre os próprios contextos de aprendizagem não-escolar. Do ponto de vista metodológico, a abordagem apoia-se num estudo de caso, iniciado em 2009, numa escola secundária do norte do país. Os dados provenientes da administração de um inquérito por questionário ao universo dos alunos que nos últimos oito anos integraram o quadro de excelência e da análise documental aos seus registos biográficos possibilitaram o esboço de algumas tendências significativas: i) intensificação da formalização dos processos de escolarização, com destaque para o reforço de práticas de ensino instrutivo e de modalidades de avaliação de tipo sumativo; ii) relação entre as aprendizagens não-escolares e os níveis de performatividade dos alunos; iii) formalização crescente dos contextos de aprendizagem não formal (fora e dentro dos muros da escola); iv) diluição das fronteiras entre o escolar e o não-escolar, transfigurando-se este último num potencial agente da performatividade; v) aliança e cumplicidade estratégica entre o mundo escolar e alguns setores do mundo não-escolar.

Semipurity of tempered Deligne cohomology

In this paper we define the formal and tempered Deligne cohomology groups, that are obtained by applying the Deligne complex functor to the complexes of formal differential forms and tempered currents respectively. We then prove the existence of a duality between them, a vanishing theorem for the former and a semipurity property for the latter. The motivation of this results comes from the study of covariant arithmetic Chow groups. The semi-purity property of tempered Deligne cohomology implies, in particular, that several definitions of covariant arithmetic Chow groups agree for projective arithmetic varieties.

Este proyecto plantea el diseño de un diplexor basado en resonadores BAW, pensado para aplicaciones de comunicaciones móviles. Éste permite a los terminales seleccionar los canales de uplink y downlink en sistemas que utilicen duplexado por división en frecuencia. Se plantean tres alternativas de diseño a partir de filtros implementados con resonadores BAW en una topología en escalera. Éstas serán evaluadas y comparadas considerando las pérdidas de inserción, el rechazo fuera de banda y las dimensiones de la estructura obtenida.

Indexació de continguts televisius: anàlisis de vídeo

Aquest és un projecte que tracta sobre la indexació automàtica de continguts televisius. És una tasca que guanyarà importància amb els imminents canvis que hi haurà en la televisió que coneixem. L'entrada de la nova televisió digital farà que hi hagi una interacció molt més fluida entre l'espectador i la cadena, a més de grans quantitats de canals, cada un amb programes de tipus totalment diferents. Tot això farà que tenir mètodes de cerca basats en els continguts d'aquests programes sigui del tot imprescindible. Així doncs, el nostre projecte està basat plenament en poder extreure alguns d'aquests descriptors que faran possible la categorització dels diferents programes televisius.

Control of calcium homeostasis in Schistosoma mansoni

Calcium signalling is fundamental for muscular contractility of Schistosoma mansoni. We have previously described the presence of transport ATPases (Na+,K+-ATPase and (Ca2+-Mg2+)-ATPase) and calcium channels (ryanodine receptors - RyR) involved in control of calcium homeostasis in this worm. Here we briefly review the main technics (ATPase activity, binding with specific radioligands, fluxes of 45Ca2+ and whole worm contractions) and results obtained in order to compare the distribution patterns of these proteins: thapsigargin-sensitive (Ca2+-Mg2+)-ATPase activity and RyR co-purified in P1 and P4 fractions mainly, which is compatible with a sarcoplasmic reticulum localization, while basal ATPase (along with Na+,K+-ATPase) and thapsigargin-resistant (Ca2+-Mg2+)-ATPase have a distinct distribution, indicative of their plasma membrane localization. Finally we attempt to integrate these contributions with data from other groups in order to propose the first synoptic model for control of calcium homeostasis in S. mansoni.

The Politics of Network Governance in Europe: The Case of Energy Regulation

Networks are considered increasingly important for policy-making. The literature on new modes of governance in Europe suggests that their horizontal coordination capacity and flexible and informal structures are particularly suitable for governing the multilevel architecture of the European polity. However, empirical evidence about the effects of networks on policy-making and public policies is still quite limited. This article uses the case of the European network of energy regulators to explore the determinants of the position of network members and, in turn, the domestic adoption of soft rules developed within this network. The empirical analysis, based on multivariate statistics and semi-directive interviews, supports the expectation that institutional complementarities increase actors' centrality in networks, while arguments based on organisational resources and age are disproved. Furthermore, results show that the overall level of adoption is considerable and that centrality might have a small positive effect on domestic adoption.

p.L1612P, a novel voltage-gated sodium channel Nav1.7 mutation inducing a cold sensitive paroxysmal extreme pain disorder.

BACKGROUND: Mutations in the SCN9A gene cause chronic pain and pain insensitivity syndromes. We aimed to study clinical, genetic, and electrophysiological features of paroxysmal extreme pain disorder (PEPD) caused by a novel SCN9A mutation. METHODS: Description of a 4-generation family suffering from PEPD with clinical, genetic and electrophysiological studies including patch clamp experiments assessing response to drug and temperature. RESULTS: The family was clinically comparable to those reported previously with the exception of a favorable effect of cold exposure and a lack of drug efficacy including with carbamazepine, a proposed treatment for PEPD. A novel p.L1612P mutation in the Nav1.7 voltage-gated sodium channel was found in the four affected family members tested. Electrophysiologically the mutation substantially depolarized the steady-state inactivation curve (V1/2 from -61.8 ± 4.5 mV to -30.9 ± 2.2 mV, n = 4 and 7, P < 0.001), significantly increased ramp current (from 1.8% to 3.4%, n = 10 and 12) and shortened recovery from inactivation (from 7.2 ± 5.6 ms to 2.2 ± 1.5 ms, n = 11 and 10). However, there was no persistent current. Cold exposure reduced peak current and prolonged recovery from inactivation in wild-type and mutated channels. Amitriptyline only slightly corrected the steady-state inactivation shift of the mutated channel, which is consistent with the lack of clinical benefit. CONCLUSIONS: The novel p.L1612P Nav1.7 mutation expands the PEPD spectrum with a unique combination of clinical symptoms and electrophysiological properties. Symptoms are partially responsive to temperature but not to drug therapy. In vitro trials of sodium channel blockers or temperature dependence might help predict treatment efficacy in PEPD.
