O processo ensino-aprendizagem: relatório de estágio

I - Inserido no Concelho de Odivelas, cuja realidade e contexto sócio cultural realçam a problemática da diversidade cultural, colocando ao professor dúvidas e dificuldades emrelação às suas práticas educativas, o Conservatório de Música D. Dinis é a escola na qual leciono desde 1993. É também local de reflexão permanente quanto aos critérios e condições que devem nortear a prática pedagógica contemporânea na área da música, cujo objetivo assenta na formação integral do aluno através da utilização de estratégias de ensino que o responsabilizem na própria aprendizagem. Considerando estes desafios, o seguinte trabalho será realizado no contexto da minha classe de violino e incidirá sobre três alunos em particular, que frequentam os seguintes graus, a saber: 1 - Iniciação (1º ciclo do ensino básico); 2 - 2º grau (2º ciclo do ensino básico); 3 - 5º grau (3º ciclo do ensino básico). Apesar de acreditar nas suas capacidades de aprendizagem e ter um cuidado especial sobre as minhas ações e os efeitos destas na aprendizagem académica e social dos meus alunos, os resultados finais são reveladores da importância da motivação, do apoio parental e da responsabilidade dos alunos na obtenção do seu próprio sucesso escolar.

Contributos para a avaliação económica de medicamentos em Portu

RESUMO: A importância da avaliação económica na área da saúde tem sido crescente ao longo das últimas três décadas. É um campo de análise multi-disciplinar pelo qual se têm vindo a interessar investigadores de todo o mundo e onde, naturalmente, a economia da saúde tem contributos significativos para dar. Contudo, é uma área ainda relativamente inexplorada em termos de investigação metodológica em Portugal. Espera-se com este trabalho colmatar algumas das lacunas existentes e lançar pontes para investigação futura. Neste estudo pretendem-se desenvolver contributos autónomos, numa óptica de resolução de problemas concretos, para a avaliação económica de medicamentos em Portugal. Em primeiro lugar abordou-se a importância da estimação dos custos nos estudos de avaliação económica em saúde. Em segundo lugar determinou-se o custo de um doente com esclerose múltipla, por nível de severidade em Portugal com recurso à metodologia de estudos custo da doença. Em terceiro lugar, aplicando a mesma metodologia, determinou-se o custo de um doente com psoríase, por nível de severidade, em Portugal. Em quarto lugar mediu-se o impacto da psoríase na qualidade de vida relacionada com a saúde dos indivíduos afectados através de dois instrumentos genéricos de medição da qualidade de vida relacionada com a saúde (SF-36 e EQ-5D) e de dois instrumentos específicos (DLQI e PDI). Em quinto lugar, foi feita a adaptação de um modelo sobre a prevenção do tromboembolismo venoso em cirurgia ortopédica ao contexto nacional com recurso a dados recolhidos numa amostra de hospitais portugueses. Foi ainda apresentada uma estimativa do impacto orçamental decorrente da inclusão, ou não, de um novo medicamento na prática nacional. ABSTRACT: The importance of economic evaluation in the health care sector has been growing in the last three decades. It is a multidisciplinary field of research that attracts attention from researchers working all over the world. It is should be noted that health economics can contribute significantly to the development of this area. However, in Portugal is difficult to find methodological contributes in this field of research. With this work one hope to be able to overcome some of the existing shortcomings. This study seeks to develop independent contributions for the economic evaluation of pharmaceuticals in Portugal, aiming to help to solve existing problems. Firstly, one approached the importance of the accurate estimation of costs in economic evaluations of pharmaceuticals. Secondly, the cost of patient with multiple sclerosis was estimated, by severity level, in Portugal, using a cost of illness methodology. In third place, employing the same methodology, the cost of patient with psoriasis by severity level was estimated for Portugal. In fourth place, the impact of psoriasis in the quality of life related to health was ascertained by two generic measures (SF-36 and EQ-5D) and two specific measures (DLQI and PDI). Lastly, a model on the prevention of venous thromboembolism in orthopedic surgery was adapted for Portugal through the inclusion of data collected in a sample of Portuguese hospita

Educação e formação de Adultos: novas rotas?

Ao longo do projeto encarou-se a Educação e Formação de Adultos como um motor para a liberdade, definida como a autonomia para se procurar e viver um destino. Destino que não é apenas o porto onde atraca o barco à chegada, mas o processo de destinação na rota. Hodiernamente vivemos atracados ao paradigma da Aprendizagem ao Longo da Vida, ancorados a processos económicos e ideológicos que ditam as orientações de atuação do Instituto de Emprego e Formação Profissional na forma com se planeiam e organizam os Cursos de Educação e Formação de Adultos. Traçaram-se as rotas que Portugal percorreu até desenvolver as políticas de Educação e Formação de Adultos atuais. Essas políticas influenciam sobremaneira a organização e planeamento dos Cursos de Educação e Formação de Adultos desenvolvidos pelo Instituto de Emprego e Formação de Vila Real que se vê agrilhoado aos ideais neoliberais, à falta de recursos, de ideais e de esperança. Procurou-se construir um projeto que conceba o planeamento e a organização dos cursos de Educação e Formação de Adultos numa ótica emancipadora da educação enraizada em contextos locais, em que as diretrizes do Estado se constituem como uma moldura mas não se restringem à rigidez do caixilho, assente em lógicas de responsabilidade comunitária em processos relacionais abertos, dialogados e críticos assentes em conteúdos vividos, aprendidos e transformados. Espera-se e deseja-se que aqueles processos comprometam de forma decisiva todos os que se vêem envolvidos neste feixe de relações a partir do qual cada um se forma, e desenvolvendo-se, se envolve na possibilidade de destinar a rota.

Legionella em meio hospitalar : qual a eficácia dos programas de prevenção nos hospitais da Região de Lisboa e Vale do Tejo : manutenção, limpeza e desinfeção de sistemas e

RESUMO - A legionella em meio hospitalar tem sido alvo de preocupação e de várias discussões, sendo esta uma bactéria patogénica que coloniza vários tipos de ambientes aquáticos (naturais e artificiais). Estas bactérias têm a particularidade de se desenvolver em meio aquático mas a infeção apenas é transmitida através de aerossóis de água contaminada, ou seja, por via aérea. Não se transmitindo de pessoa para pessoa. Pelas suas características os sistemas de arrefecimento de ar, nomeadamente as torres de arrefecimento, condensadores evaporativos, humidificadores e sistemas de ar condicionado, são fontes importantes de disseminação da legionella. Assim surge a necessidade da existência de programas de prevenção, que deverão ter em conta uma adequada manutenção, limpeza e desinfeção. Dada a quantidade de frequentadores assim como da especificidade dos mesmos, em meio hospitalar é particularmente importante a eficácia destes sistemas. Ou seja, os sistemas de arrefecimento em hospitais devem, para além de garantir o conforto térmico, ser responsáveis por manter a qualidade do ar e reduzir os riscos existentes a ele associados. O presente estudo pretende conhecer a verdadeira eficácia dos programas de manutenção e vigilância da Legionella, apenas nos sistemas de arrefecimento. Trata-se então de um estudo exploratório, descritivo recolha desta informação in-loco dos sistemas em estudo, de X hospitais da cidade de Lisboa. Na metodologia serão utilizadas grelhas de observação e resultados de colheita de água dos locais de maior risco. A realização deste estudo visa obter um retrato do panorama existente e contribuir para o início de novos estudos epidemiológicos.

Res Publica: Citizenship and Political Representation in Portugal, 1820-1926

The term res publica (literally “thing of the people”) was coined by the Romans to translate the Greek word politeia, which, as we know, referred to a political community organised in accordance with certain principles, amongst which the notion of the “good life” (as against exclusively private interests) was paramount. This ideal also came to be known as political virtue. To achieve it, it was necessary to combine the best of each “constitutional” type and avoid their worst aspects (tyranny, oligarchy and ochlocracy). Hence, the term acquired from the Greeks a sense of being a “mixed” and “balanced” system. Anyone that was entitled to citizenship could participate in the governance of the “public thing”. This implied the institutionalization of open debate and confrontation between interested parties as a way of achieving the consensus necessary to ensure that man the political animal, who fought with words and reason, prevailed over his “natural” counterpart. These premises lie at the heart of the project which is now being presented under the title of Res Publica: Citizenship and Political Representation in Portugal, 1820-1926. The fact that it is integrated into the centenary commemorations of the establishment of the Republic in Portugal is significant, as it was the idea of revolution – with its promise of rupture and change – that inspired it. However, it has also sought to explore events that could be considered the precursor of democratization in the history of Portugal, namely the vintista, setembrista and patuleia revolutions. It is true that the republican regime was opposed to the monarchic. However, although the thesis that monarchy would inevitably lead to tyranny had held sway for centuries, it had also been long believed that the monarchic system could be as “politically virtuous” as a republic (in the strict sense of the word) provided that power was not concentrated in the hands of a single individual. Moreover, various historical experiments had shown that republics could also degenerate into Caesarism and different kinds of despotism. Thus, when absolutism began to be overturned in continental Europe in the name of the natural rights of man and the new social pact theories, initiating the difficult process of (written) constitutionalization, the monarchic principle began to be qualified as a “monarchy hedged by republican institutions”, a situation in which not even the king was exempt from isonomy. This context justifies the time frame chosen here, as it captures the various changes and continuities that run through it. Having rejected the imperative mandate and the reinstatement of the model of corporative representation (which did not mean that, in new contexts, this might not be revived, or that the second chamber established by the Constitutional Charter of 1826 might not be given another lease of life), a new power base was convened: national sovereignty, a precept that would be shared by the monarchic constitutions of 1822 and 1838, and by the republican one of 1911. This followed the French example (manifested in the monarchic constitution of 1791 and in the Spanish constitution of 1812), as not even republicans entertained a tradition of republicanism based upon popular sovereignty. This enables us to better understand the rejection of direct democracy and universal suffrage, and also the long incapacitation (concerning voting and standing for office) of the vast body of “passive” citizens, justified by “enlightened”, property- and gender-based criteria. Although the republicans had promised in the propaganda phase to alter this situation, they ultimately failed to do so. Indeed, throughout the whole period under analysis, the realisation of the potential of national sovereignty was mediated above all by the individual citizen through his choice of representatives. However, this representation was indirect and took place at national level, in the hope that action would be motivated not by particular local interests but by the common good, as dictated by reason. This was considered the only way for the law to be virtuous, a requirement that was also manifested in the separation and balance of powers. As sovereignty was postulated as single and indivisible, so would be the nation that gave it soul and the State that embodied it. Although these characteristics were common to foreign paradigms of reference, in Portugal, the constitutionalization process also sought to nationalise the idea of Empire. Indeed, this had been the overriding purpose of the 1822 Constitution, and it persisted, even after the loss of Brazil, until decolonization. Then, the dream of a single nation stretching from the Minho to Timor finally came to an end.

Therapeutics bioconjugates: evaluation of iminoboronates as payload delivery system for cancer

The advent of bioconjugation impacted deeply the world of sciences and technology. New biomolecules were found, biological processes were understood, and novel methodologies were formed due to the fast expansion of this area. The possibility of creating new effective therapies for diseases like cancer is one of big applications of this now big area of study. Off target toxicity was always the problem of potent small molecules with high activity towards specific tumour targets. However, chemotherapy is now selective due to powerful linkers that connect targeting molecules with affinity to interesting biological receptors and cytotoxic drugs. This linkers must have very specific properties, such as high stability in plasma, no toxicity, no interference with ligand affinity nor drug potency, and at the same time, be able to lyse once inside the target molecule to release the therapeutic warhead. Bipolar environments between tumour intracellular and extracellular medias are usually exploited by this linkers in order to complete this goal. The work done in this thesis explores a new model for that same task, specific cancer drug delivery. Iminoboronates were studied due to its remarkable selective stability towards a wide pH range and endogenous molecules. A fluorescence probe was design to validate this model by creating an Off/On system and determine the payload release location in situ. A process was optimized to synthetize the probe 8-(1-aminoethyl)-7-hydroxy-coumarin (1) through a reductive amination reaction in a microwave reactor with 61 % yield. A method to conjugate this probe to ABBA was also optimized, obtaining the iminoboronate in good yields in mild conditions. The iminoboronate model was studied regarding its stability in several simulated biological environments and each half-life time was determined, showing the conjugate is stable most of the cases except in tumour intracellular systems. The construction of folate-ABBA-coumarin bioconjugate have been made to complete this evaluation. The ability to be uptaken by a cancer cell through endocytosis process and the conjugation delivery of coumarin fluorescence payload are two features to hope for in this construct.

Stem Cell Transplantation for Retinal Degenerations

Within the last few years, several reports have revealed that cell transplantation can be an effective way to replace lost neurons in the central nervous system (CNS) of patients affected with neurodegenerative diseases. Concerning the retina, the concept that newborn photoreceptors can integrate the retina and restore some visual functions was univocally demonstrated recently in the mouse eye (MacLaren et al. 2006) and remains to be achieved in human. These results pave the way to a standard approach in regenerative medicine aiming to replace lost photoreceptors. With the discovery of stem cells a great hope has appeared towards elaborating protocols to generate adequate cells to restore visual function in different retinal degeneration processes. Retinal stem cells (RSCs) are good candidates to repair the retina and are present throughout the retina development, including adulthood. However, neonatal mouse RSCs derived from the radial glia population have a different potential to proliferate and differentiate in comparison to adult RSCs. Moreover, we observed that adult mouse RSCs, depending on the culture conditions, have a marked tendency to transform, whereas neonatal RSCs show subtle chromosome abnormalities only after extensive expansion. These characteristics should help to identify the optimal cell source and culture conditions for cell transplantation studies. These results will be discussed in light of other studies using RSCs as well as embryonic stem cells. Another important factor to consider is the host environment, which plays a crucial role for cell integration and which was poorly studied in the normal and the diseased retina. Nonetheless, important results were recently generated to reconsider cell transplantation strategy. Perspectives to enhance cell integration by manipulating the environment will also be presented.

New York City: "gilt cage" or "promised land" ? : representations of urban space in Edith Wharton and Anzia Yezierska

This thesis explores the importance of literary New York City in the urban narratives of Edith Wharton and Anzia Yezierska. It specifically looks at the Empire City of the Progressive Period when the concept of the city was not only a new theme but also very much a typical American one which was as central to the American experience as had been the Western frontier. It could be argued, in fact, that the American city had become the new frontier where modern experiences like urbanization, industrialization, immigration, and also women's emancipation and suffrage, caused all kinds of sensations on the human scale from smoothly lived assimilation and acculturation to deeply felt alienation because of the constantly shifting urban landscape. The developing urban space made possible the emergence of new female literary protagonists like the working girl, the reformer, the prostitute, and the upper class lady dedicating her life to 'conspicuous consumption'. Industrialization opened up city space to female exploration: on the one hand, upper and middle class ladies ventured out of the home because of the many novel urban possibilities, and on the other, lower class and immigrant girls also left their domestic sphere to look for paid jobs outside the home. New York City at the time was not only considered the epicenter of the world at large, it was also a city of great extremes. Everything was constantly in flux: small brownstones made way for ever taller skyscrapers and huge waves of immigrants from Europe pushed native New Yorkers further uptown on the island, adding to the crowdedness and intensity of the urban experience. The city became a polarized urban space with Fifth Avenue representing one end of the spectrum and the Lower East Side the other. Questions of space and the urban home greatly mattered. It has been pointed out that the city setting functions as an ideal means for the display of human nature as well as social processes. Narrative representations of urban space, therefore, provide a similar canvas for a protagonist's journey and development. From widely diverging vantage points both Edith Wharton and Anzia Yezierska thus create a polarized city where domesticity is a primal concern. Looking at all of their New York narratives by close readings of exterior and interior city representations, this thesis shows how urban space greatly affects questions of identity, assimilation, and alienation in literary protagonists who cannot escape the influence of their respective urban settings. Edith Wharton's upper class "millionaire" heroines are framed and contained by the city interiors of "old" New York, making it impossible for them to truly participate in the urban landscape in order to develop outside of their 'Gilt Cages'. On the other side are Anzia Yezierska's struggling "immigrant" protagonists who, against all odds, never give up in their urban context of streets, rooftops, and stoops. Their New York City, while always challenging and perpetually changing, at least allows them perspectives of hope for a 'Promised Land' in the making. Central for both urban narrative approaches is the quest for a home as an architectural structure, a spiritual resting place, and a locus for identity forming. But just as the actual city embraces change, urban protagonists must embrace change also if they desire to find fulfillment and success. That this turns out to be much easier for Anzia Yezierska's driven immigrants rather than for Edith Wharton's well established native New Yorkers is a surprising conclusion to this urban theme.

Early Tithonian Saturnalidae (Radiolaria) from the Solnhofen area (Southern Franconian Alb, Southern Germany)

In order to complete the study of the very rich early Tithonian (Hybonoticeras hybonotum Zone) radiolarian fauna from the Muhlheim Member of the Mornsheim Formation outcropping in the Solnhofen area, the taxa of the family Saturnalidae are described. Although rather rare, the Saturnalidae of this member contain 14 species, ten of which are new. These species belong to four genera, one of which is new (Moebicircus n. gen.), and two subfamilies (Hexasaturnalinae and Saturnalinae). The taxonomy at generic level of these late Jurassic radiolarians is founded on the basis of the position of the blades along the ring and number and morphology of the spines. Type of spines (simple or forked) has either species level value or none, depending on species. Special attention was given to anomalies, which sometimes are rather frequent, since they can give information of paleobiological and paleoecological orders. Among them frequent cases of open ring and additional spines with Dicerosaturnalis and Siamese twins skeletons with Spongosaturninus and Dicerosaturnalis are to be noted. The authors hope that this new taxonomy will give a better image of the evolution and radiation of the Saturnalidae during the Tithonian.

ESCMID* guideline for the diagnosis and management of Candida diseases 2012: developing European guidelines in clinical microbiology and infectious diseases.

The process to develop a guideline in a European setting remains a challenge. The ESCMID Fungal Infection Study Group (EFISG) successfully achieved this endeavour. After two face-to-face meetings, numerous telephone conferences, and email correspondence, an ESCMID task force (basically composed of members of the Society's Fungal Infection Study Group, EFISG) finalized the ESCMID diagnostic and management/therapeutic guideline for Candida diseases. By appreciating various patient populations at risk for Candida diseases, four subgroups were predefined, mainly ICU patients, paediatric, HIV/AIDS and patients with malignancies including haematopoietic stem cell transplantation. Besides treatment recommendations, the ESCMID guidelines provide guidance for diagnostic procedures. For the guidelines, questions were formulated to phrase the intention of a given recommendation, for example, outcome. The recommendation was the clinical intervention, which was graded by a score of A-D for the 'Strength of a recommendation'. The 'level of evidence' received a score of I-III. The author panel was approved by ESCMID, European Organisation for Research and Treatment of Cancer, European Group for Blood and Marrow Transplantation, European Society of Intensive Care Medicine and the European Confederation of Medical Mycology. The guidelines followed the framework of GRADE and Appraisal of Guidelines, Research, and Evaluation. The drafted guideline was presented at ECCMID 2011 and points of discussion occurring during that meeting were incorporated into the manuscripts. These ESCMID guidelines for the diagnosis and management of Candida diseases provide guidance for clinicians in their daily decision-making process.

Revised definitions of invasive fungal disease from the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) Consensus Group.

BACKGROUND: Invasive fungal diseases are important causes of morbidity and mortality. Clarity and uniformity in defining these infections are important factors in improving the quality of clinical studies. A standard set of definitions strengthens the consistency and reproducibility of such studies. METHODS: After the introduction of the original European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) Consensus Group definitions, advances in diagnostic technology and the recognition of areas in need of improvement led to a revision of this document. The revision process started with a meeting of participants in 2003, to decide on the process and to draft the proposal. This was followed by several rounds of consultation until a final draft was approved in 2005. This was made available for 6 months to allow public comment, and then the manuscript was prepared and approved. RESULTS: The revised definitions retain the original classifications of "proven," "probable," and "possible" invasive fungal disease, but the definition of "probable" has been expanded, whereas the scope of the category "possible" has been diminished. The category of proven invasive fungal disease can apply to any patient, regardless of whether the patient is immunocompromised, whereas the probable and possible categories are proposed for immunocompromised patients only. CONCLUSIONS: These revised definitions of invasive fungal disease are intended to advance clinical and epidemiological research and may serve as a useful model for defining other infections in high-risk patients.

Sudden cardiac death in forensic medicine - Swiss recommendations for a multidisciplinary approach.

Sudden cardiac death (SCD) is by definition unexpected and cardiac in nature. The investigation is almost invariably performed by a forensic pathologist. Under these circumstances the role of the forensic pathologist is twofold: (1.) to determine rapidly and efficiently the cause and manner of death and (2.) to initiate a multidisciplinary process in order to prevent further deaths in existing family members. If the death is determined to be due to "natural" causes the district attorney in charge often refuses further examinations. However, additional examinations, i.e. extensive histopathological investigations and/or molecular genetic analyses, are necessary in many cases to clarify the cause of death. The Swiss Society of Legal Medicine created a multidisciplinary working group together with clinical and molecular geneticists and cardiologists in the hope of harmonising the approach to investigate SCD. The aim of this paper is to close the gap between the Swiss recommendations for routine forensic post-mortem cardiac examination and clinical recommendations for genetic testing of inherited cardiac diseases; this is in order to optimise the diagnostic procedures and preventive measures for living family members. The key points of the recommendations are (1.) the forensic autopsy procedure for all SCD victims under 40 years of age, (2.) the collection and storage of adequate samples for genetic testing, (3.) communication with the families, and (4.) a multidisciplinary approach including cardiogenetic counselling.

Aspects de la représentation de l'autre dans les romans grecs et "Les Métamorphoses" d'Apulée

Les romans grecs et les Métamorphoses d'Apulée - même si les modalités sont différentes pour ce dernier - sont des fictions en prose qui fonctionnent autour de topoi auxquels la figure de l'Autre n'échappe pas. Bien que le monde grec soit alors radicalement différent de ce qu'il était au Ve siècle avant J.-C, période à laquelle l'identité grecque est construite par opposition à la figure du barbare, les romanciers qui prennent la plume à partir du 1er siècle avant notre ère utilisent un certain nombre de stéréotypes hérités de l'époque classique, alors mise à l'honneur par le mouvement de la Seconde Sophistique. Il s'agit d'étudier dans le détail certains éléments de la représentation de l'Autre pour déterminer qui il est, comment il se comporte, ce qui le constitue en Autre. Puis, à partir de cette esquisse, nécessairement incomplète, d'évaluer ce que cette représentation peut induire sur l'image de l'identité grecque à l'époque impériale, par le jeu de miroir que F. Hartog a décelé dans l'oeuvre d'Hérodote. Une première partie est consacrée aux rapports entre l'homme et l'animal ainsi qu'à l'image de la sauvagerie, ce qui permet d'explorer les bornes romanesques de l'humanité. La seconde partie s'attache à des éléments que l'époque classique a plus particulièrement mis en avant pour distinguer les Grecs des non-Grecs : le critère de la langue, l'art de faire la guerre et le discours politique qui est tenu sur les institutions barbares. La troisième partie étudie la place des dieux et des pratiques religieuses dans la définition de l'Autre. J'espère ainsi contribuer à la compréhension du genre romanesque et des représentations culturelles de l'empire « gréco-romain ». -- The Greek novels and The Metamorphoses of Apuleius, even if it is in different terms for the last, are prose fictions which are based on topoi, and the figure of the Other is one of them. Although the Greek world was radically different of what it was in the fifth century BC, time during which Greek identity is contructed as opposed to the figure of the barbaros, the authors of novels, who wrote from the first century BC onward, used some stereotypes inherited from classical period, which was celebrated by the Second Sophistic movement. The aim of this thesis is to study in detail some elements of the representation of the Other to determine who it is, how he behaves, what makes him other. Then, from this sketch, necessarily incomplete, to evaluate what this representation says about the image of Greek identity in the imperial age, according to the play of the mirror detected by F. Hartog in the text of Herodotus. The first part of the thesis is dedicated to the relationship between man and animal and to the image of savagery, in order to explore the novelistic limits of humanity. The second part concentrates on elements that classical period had particularly insisted on to promote the distinction between Greeks and non-Greeks : the linguistic criterion, the way to make war, and the politic discourse on the barbaric institutions. The third part study the place of the gods and of religious practices in the definition of the Other. I hope to contribute to the understanding of novel genre and of cultural representations of the « greco- roman- empire ».
