English Language Learning Inside and Outside the Classroom in Portugal

This study investigates the way of learning the English language in Portugal. First-year students of the faculty of Social Sciences and Humanities of New University of Lisbon were selected as participants in the case study. As data collection tools a questionnaire and focus-groups were used. 115 students completed the designed questionnaire and after that 12 students were selected for the more detailed focus-group discussions. Results of the research show that most part of the students´ English knowledge is received from outside the classroom by means of movies, songs, computer games, the Internet, communication with friends and other sources. Also, the results show that motivation is very important in language learning process and motivated students acquire the language faster and easier.

A domain specific language for domotic systems

To cope with modernity, the interesting of having a fully automated house has been increasing over the years, as technology evolves and as our lives become more stressful and overloaded. An automation system provides a way to simplify some daily tasks, allowing us to have more spare time to perform activities where we are really needed. There are some systems in this domain that try to implement these characteristics, but this kind of technology is at its early stages of evolution being that it is still far away of empowering the user with the desired control over a habitation. The reason is that the mentioned systems miss some important features such as adaptability, extension and evolution. These systems, developed from a bottom-up approach, are often tailored for programmers and domain experts, discarding most of the times the end users that remain with unfinished interfaces or products that they have difficulty to control. Moreover, complex behaviors are avoided, since they are extremely difficult to implement mostly due to the necessity of handling priorities, conflicts and device calibration. Besides, these solutions are only reachable at very high costs, yet they still have the limitation of being difficult to configure by non-technical people once in runtime operation. As a result, it is necessary to create a tool that allows the execution of several automated actions, with an interface that is easy to use but at the same time supports all the main features of this domain. It is also desirable that this tool is independent of the hardware so it can be reused, thus a Model Driven Development approach (MDD) is the ideal option, as it is a method that follows those principles. Since the automation domain has some very specific concepts, the use of models should be combined with a Domain Specific Language (DSL). With these two methods, it is possible to create a solution that is adapted to the end users, but also to domain experts and programmers due to the several levels of abstraction that can be added to diminish the complexity of use. The aim of this thesis is to design a Domain Specific Language (DSL) that uses the Model Driven Development approach (MDD), with the purpose of supporting Home Automation (HA) concepts. In this implementation, the development of simple and complex scenarios should be supported and will be one of the most important concerns. This DSL should also support other significant features in this domain, such as the ability to schedule tasks, which is something that is limited in the current existing solutions.

About using serious games to teach (Portuguese) sign language

Sign language is the form of communication used by Deaf people, which, in most cases have been learned since childhood. The problem arises when a non-Deaf tries to contact with a Deaf. For example, when non-Deaf parents try to communicate with their Deaf child. In most cases, this situation tends to happen when the parents did not have time to properly learn sign language. This dissertation proposes the teaching of sign language through the usage of serious games. Currently, similar solutions to this proposal do exist, however, those solutions are scarce and limited. For this reason, the proposed solution is composed of a natural user interface that is intended to create a new concept on this field. The validation of this work, consisted on the implementation of a serious game prototype, which can be used as a source for learning (Portuguese) sign language. On this validation, it was first implemented a module responsible for recognizing sign language. This first stage, allowed the increase of interaction and the construction of an algorithm capable of accurately recognizing sign language. On a second stage of the validation, the proposal was studied so that the pros and cons can be determined and considered on future works.

Improving Learners’ Motivation through Feedback in English Language Teaching and Learning at Polytechnic School in Benguela, Angola

Currently, it is widely perceived among the English as a Foreign Language (EFL) teaching professionals, that motivation is a central factor for success in language learning. This work aims to examine and raise teachers’ awareness about the role of assessment and feedback in the process of language teaching and learning at polytechnic school in Benguela to develop and/or enhance their students’ motivation for learning. Hence the paper defines and discusses the key terms and, the techniques and strategies for an effective feedback provision in the context under study. It also collects data through the use of interview and questionnaire methods, and suggests the assessment and feedback types to be implemented at polytechnic school in Benguela

Donations of non-financial resources: The motivation and consequences of measuring and accounting for it

This thesis focus on the measurement and accounting of contributions received by nonprofit organizations, as they are a significant component of revenues nowadays. A survey was developed and forward to 38 different NPOs, with the goal of understanding their motivations and what advantages and disadvantages they believe would result if they start to measure and account for all kinds of contributions. They presented many advantages from this practice; however, some are not doing it due to the difficulties in valuing contributions with no market value which would require a higher workload, waste of resources and time to be taken from other important activities.

The concept of soft power offers the opportunity for the States, under the current power shifts, to thrive, in a competitive and globalised scene, shaping o t hers' preference in accordance with their goals. Portugal, though it i s a small country, has soft power skills, according with specialized rankings, due to i t s geography and climate, main economic activities, historical role, legal framework, culture and language. Therefore, we can and we should develop public policies to optimize our resources, converting them in planned outcomes. On the other hand, public entities engaged with foreign trade, investment and tour ism, aid f or development, promotion of culture and language should be structured in or-der to strengthen the performance of Portugal in this area. Being a member of the European Union or of the Community of Portuguese Speaking Countries is, at last, essential to expand our global presence. In this Master's work project, I decided to make a critical analysis of legislation related with public diplomacy i n Portugal, together wi th research about the approach of two other countries (United Kingdom and Finland) to the same topic, for the sake of improvement.

Leadership in Angola and Mozambique: How Portuguese leaders overcome the human resources challenge and contribute to organizational success

This Work Project presents human resources as one of the major challenges that Portuguese leaders meet in Angola and Mozambique. The main goal is to understand the role of leaders in translating this challenge into benefits for their own business and the African society. To conduct this study 13 leaders who work in Portugal and Africa were interviewed. Then, a framework was constructed based on the two ways these leaders recognize the importance of their employees for sustainable growth – financial incentives or/and personal development. The main conclusion here is that individually, incentives and personal development are not effective methods. Because of this, an employee empowerment process is proposed that encloses both, along with the leaders’ personal qualities needed to implement that “ideal” process.

Reallocation of resources between the tradable and non-tradable sector in Portugal: Assessing the degree of structural transformation in the Portuguese economy

Portugal implemented a large number of structural reforms in the recent years, which are expected to enhance the allocation of resources in the economy, namely from the non-tradable to tradable sector. We argue that the methodology to identify the tradable sector used by some international institutions is outdated and may hamper an accurate assessment of the progress achieved so far. Based on an enhanced methodology to identify the tradable sector, we are able to provide a more accurate, clearer picture of the recent structural developments of the Portuguese economy.

Os romances juvenis de Álvaro Magalhães

With his works translated in countries such as Spain, France and Brazil, Álvaro Magalhães is not only one of the great writers of Portuguese and Lusophone juvenile fiction, but also one of the most prominent names in European and world literature. Through the various thematic and narrative resources that he employs in the creation of a unique language, among the multiple and unusual senses of serious and humorous, among the elements of various domains of knowledge and universal culture that he invokes and contrasts, this author has a unique place in universe of novels aimed primarily at young readers.

A indústria de defesa na cooperação Brasil-Portugal

The global dynamics of alliances are strongly determined by the level of cooperation among states. This cooperation can be embodied in various aspects, but the level of defense and security cooperation becomes usually more doctrinal and lasting. By the nature of sovereignty that instills in the bilateral relationship, cooperation at defense and security level can leverages other forms of cooperation. The circumstances and relational balance between Brazil and Portugal seem to evolve towards distancing opportunities, despite they are culturally and institutionally untainted. The economic dynamics, the strategic projection in global sustainability terms, the scale and ambition of Brazilian regional leadership, contrasts with the actual context of Portugal, distancing himself both on the stage where they operate. On the other hand, the historical and cultural roots, the language, the affinity of the peoples of CPLP and some opportunities for economic niches, trend to attract both countries. The condition of Portugal in NATO and Europe, coupled with the ability to export technical and human resources to value-added for Brazil, seems also to become approaching factors. On the balance of these dynamics, there is a set of exogenous factors (economic, external global relations matrix, regional stability, among others), which are not always controlled by any of both countries. These factors call for strong capacity for foresight analysis and decision making, with the inherent risk. There is cooperation vectors that are not apparently penalized by geographic distance, or by the difference of realities. Among these vectors we shall highlight synergies in technological niches, highly tradable goods and, mostly, using the domain of dual technologies. The thirteen niches herein identified are: Monitoring, Navigation, Command and Control, Electronics, Optoelectronics, Communication and remote sensing, Information Technologies, Flight Simulation, Specialized Training, Fiber Optic Sensors, Materials Engineering, Nanotechnology and Communications. Cumulating with identified opportunities in traditional relational framework, both countries are growing (in geography and economic terms) into the Atlantic, making it a central element in the bilateral approach. By being at the same time a growing stage of disputes and which stability tends to be threatened, it will be done an analysis of these synergistic vectors, superimposed on the impact on Atlantic securitization process.

Estrutura Conceptual do Relato Financeiro : Da Definição de um Domínio à Sua Análise para uma Sociedade em Rede

Considerando a língua como um produto da sociedade, mas também como um meio fundamental para o estabelecimento de relações entre os homens, procuramos perceber o seu lugar na sociedade globalizada, com o objectivo de desenvolver uma metodologia de análise terminológica que contribua para uma maior qualidade da comunicação especializada na sociedade em rede. Este trabalho está organizado em duas partes, sendo a primeira dedicada à reflexão sobre o papel da língua na sociedade em rede, focando questões essenciais em torno da tensão existente entre o multilinguismo e a hegemonia do inglês enquanto lingua franca, sobretudo no espaço europeu. Interessa-nos, por um lado, reflectir sobre a definição de políticas linguísticas, concretamente na Europa multilingue dos 28, e, por outro, salientar o papel preponderante que a língua tem na transmissão do conhecimento. A segunda parte deste trabalho concretiza a investigação efectuada na primeira com base na análise do relato financeiro, um domínio do saber que não só é inerentemente multilingue ¾ porque a sua aplicação é transnacional ¾ mas também reflecte a tensão identificada na primeira parte, na medida em que o inglês assume, no mundo dos negócios em geral e nos mercados financeiros em particular, o papel hegemónico de lingua franca. A abordagem terminológica que defendemos é semasiológica para fins onomasiológicos, pelo que partimos da análise do texto de especialidade, organizado em corpora de especialidade. Discutimos subsequentemente os resultados da nossa análise com os especialistas que os irão validar e cuja colaboração em diversos vi momentos do processo de análise terminológica e conceptual é fundamental para garantir a qualidade dos recursos terminológicos produzidos. Nesta óptica, exploramos um corpus de textos legislativos no âmbito do Sistema de Normalização Contabilística (SNC), de modo a delinearmos uma metodologia de trabalho que, no futuro, conduzirá à construção de uma base de dados terminológica do relato financeiro. Concomitantemente, efectuamos também um estudo sobre a Estrutura Conceptual do SNC, para o qual elaboramos uma comparação ao nível da tradução especializada no relato financeiro, com base num corpus paralelo composto pela legislação contabilística internacional endossada pela União Europeia. Utilizamos o corpus paralelo constituído por textos redigidos originalmente em inglês e traduzidos para português, em articulação com o corpus de especialidade criado com a legislação relativa ao normativo contabilístico português, para testar uma metodologia de extracção de equivalentes. Defendemos, por fim, que a harmonização no relato financeiro para além de se reger por políticas contabilísticas comuns, deve ter subjacentes questões terminológicas. É necessário, portanto, harmonizar a terminologia do relato financeiro, possibilitando aos especialistas uma comunicação em português isenta da interferência do inglês herdado das normas internacionais, através dos dois processos que identificamos: a tradução e a adaptação das Normas Internacionais de Contabilidade.

Chlorite Dismutase from perchlorate reducing bacteria. A potential biocatalyst to eliminate chlorinated species from polluted water resources and industrial wastes

Magnetospirillum (M.) sp. strain Lusitani, a perchlorate reducing bacteria (PRB), was previously isolated from a wastewater treatment plant and phylogenetic analysis was performed to classify the isolate. The DNA sequence of the genes responsible for perchlorate reduction and chlorite dismutation was determined and a model was designed based on the physiological roles of the proteins involved in the pcr-cld regulon. Chlorite dismutase (Cld) was purified from Magnetospirillum sp. strain Lusitani cells grown in anaerobiosis in the presence of perchlorate. The protein was purified up to electrophoretic grade using HPLC techniques as a 140 kDa homopentamer comprising five ~28 kDa monomers. Steady-state kinetic studies showed that the enzyme follows a Michaelis-Menten model with optimal pH and temperature of 6.0 and 5°C, respectively. The average values for the kinetic constants KM and Vmax were respectively 0.56 mM and 10.2 U, which correspond to a specific activity of 35470 U/mg and a turnover number of 16552 s-1. Cld from M. sp. strain Lusitani is inhibited by the product chloride, but not by dioxygen. Inhibition constants KiC= 460 mM and KiU= 480 mM indicated that sodium chloride is a weak mixed inhibitor of Cld, with a slightly stronger competitive character. The X-ray crystallography structure of M. sp. strain Lusitani Cld was solved at 3.0 Å resolution. In agreement with cofactor content biochemical analysis, the X-ray data showed that each Cld monomer harbors one heme b coordinated by a histidine residue (His188), hydrogen-bonded to a conserved glutamic acid residue (Glu238). The conserved neighboring arginine residue (Arg201) important for substrate positioning, was found in two different conformations in different monomers depending on the presence of the exogenous ligand thiocyanate. UV-Visible and CW-EPR spectroscopies were used to study the effect of redox agents, pH and exogenous ligands on the heme environment.

An analysis of associations between human resources practices, affective commitment, exhaustion and cynicism of temportary workers

This research examines the relationships between Human Resources Practices (HRP) and affective commitment, exhaustion, and cynicism of temporary workers. Furthermore, voluntariness and tenure with the client organization are assumed in the analysis as moderators. A sample of Temporary Agency workers was surveyed. It was assumed that HRP positively relates with affective commitment, while negatively with exhaustion and cynicism. Results confirmed the proposed relationships. Regarding the moderators, it has been proved that voluntariness partially weakens the relationships between HRP and temporary workers’ outcomes. However, contrary to the hypothesis, this effect cannot be affirmed also for the tenure with the client organization. Previous literature as well as implications of the findings are discussed.
