A doença oncológica no fórum da História: breve síntese sobre a evolução da luta anticancerosa em Portugal

Introdução – A doença oncológica tem sido assunto de abordagem historiográfica particularmente abundante no contexto internacional. No caso português só recentemente começaram a surgir os primeiros trabalhos em redor desta ampla temática. Objetivos – Revolvendo em torno da emergência e estruturação da luta anticancerosa no âmbito internacional, pretende-se apresentar uma breve síntese sobre a evolução deste fenómeno em Portugal na primeira metade do século XX. Metodologia – Análise documental. Qualitativa e heurística. Resultados/Discussão/Considerações finais – A luta contra a doença oncológica em Portugal não destoou do contexto médico-científico e do movimento internacional anticanceroso da primeira metade do século XX. No entanto, a emergência e a institucionalização do projeto anticanceroso nacional apresentou algumas particularidades. Inserido entre uma especialidade médica em processo de afirmação e as necessidades assistenciais dos cancerosos, resultou da conjugação de uma série de fatores que ultrapassam a mera assimilação de novas tecnologias médicas ou da criação de um espaço próprio para a prática da oncologia. Tornou-se também num meio para realizar um trabalho intenso de educação para a saúde, num instrumento de ponta na formação médica especializada e numa referência de modernidade científica no contexto do Estado Novo.

Beyond methodological nationalism: The contribution of Robert E. Park to the history of intercultural communication

The legacy of nineteenth century social theory followed a “nationalist” model of society, assuming that analysis of social realities depends upon national boundaries, taking the nation-state as the primary unit of analysis, and developing the concept of methodological nationalism. This perspective regarded the nation-state as the natural - and even necessary - form of society in modernity. Thus, the constitution of large cities, at the end of the 19th century, through the intense flows of immigrants coming from diverse political and linguistic communities posed an enormous challenge to all social research. One of the most significant studies responding to this set of issues was The Immigrant Press and its Control, by Robert E. Park, one of the most prominent American sociologists of the first half of the 20th century. The Immigrant Press and its Control was part of a larger project entitled Americanization Studies: The Acculturation of Immigrant Group into American Society, funded by the Carnagie Corporation following World War I, taking as its goal to study the so-called “Americanization methods” during the 1920s. This paper revisits that particular work by Park to reveal how his detailed analysis of the role of the immigrant press overcame the limitations of methodological nationalism. By granting importance to language as a tool uniting each community and by showing how the strength of foreign languages expressed itself through the immigrant press, Park demonstrated that the latter produces a more ambivalent phenomenon than simply the assimilation of immigrants. On the one hand, the immigrant press served as a connecting force, driven by the desire to preserve the mother tongue and culture while at the same time awakening national sentiments that had, until then, remained diffuse. Yet, on the other hand, it facilitated the adjustment of immigrants to the American context. As a result, Park’s work contributes to our understanding of a particular liminal moment inherent within many intercultural contexts, the space between emigrant identity (emphasizing the country of origin) and immigrant identity (emphasizing the newly adopted country). His focus on the role played by media in the socialization of immigrant groups presaged later work on this subject by communication scholars. Focusing attention on Park’s research leads to other studies of the immigrant experience from the same period (e.g., Thomas & Znaniecki, The Polish Peasant in Europe and America), and also to insights on multi-presence and interculturality as significant but often overlooked phenomena in the study of immigrant socialization.

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.

Autonomic Activities in the Execution of Scientific Workflows: Evaluation of the AWARD Framework

Workflows have been successfully applied to express the decomposition of complex scientific applications. However the existing tools still lack adequate support to important aspects namely, decoupling the enactment engine from tasks specification, decentralizing the control of workflow activities allowing their tasks to run in distributed infrastructures, and supporting dynamic workflow reconfigurations. We present the AWARD (Autonomic Workflow Activities Reconfigurable and Dynamic) model of computation, based on Process Networks, where the workflow activities (AWA) are autonomic processes with independent control that can run in parallel on distributed infrastructures. Each AWA executes a task developed as a Java class with a generic interface allowing end-users to code their applications without low-level details. The data-driven coordination of AWA interactions is based on a shared tuple space that also enables dynamic workflow reconfiguration. For evaluation we describe experimental results of AWARD workflow executions in several application scenarios, mapped to the Amazon (Elastic Computing EC2) Cloud.

Non-colorectal intestinal tract carcinomas in inflammatory bowel disease: results of the 3rd ECCO Pathogenesis Scientific Workshop (II)

Patients with inflammatory bowel diseases (IBD) have an excess risk of certain gastrointestinal cancers. Much work has focused on colon cancer in IBD patients, but comparatively less is known about other more rare cancers. The European Crohn's and Colitis Organization established a pathogenesis workshop to review what is known about these cancers and formulate proposals for future studies to address the most important knowledge gaps. This article reviews the current state of knowledge about small bowel adenocarcinoma, ileo-anal pouch and rectal cuff cancer, and anal/perianal fistula cancers in IBD patients.

A teaching-learning sequence of colour informed by history and philosophy of science

In this work, we present a teaching-learning sequence on colour intended to a pre-service elementary teacher programme informed by History and Philosophy of Science. Working in a socio-constructivist framework, we made an excursion on the history of colour. Our excursion through history of colour, as well as the reported misconception on colour helps us to inform the constructions of the teaching-learning sequence. We apply a questionnaire both before and after each of the two cycles of action-research in order to assess students’ knowledge evolution on colour and to evaluate our teaching-learning sequence. Finally, we present a discussion on the persistence of deep-rooted alternative conceptions.

A didactic sequence of elementary geometric optics Informed by history and philosophy of science

The concepts and instruments required for the teaching and learning of geometric optics are introduced in the didactic processwithout a proper didactic transposition. This claim is secured by the ample evidence of both wide- and deep-rooted alternative concepts on the topic. Didactic transposition is a theory that comes from a reflection on the teaching and learning process in mathematics but has been used in other disciplinary fields. It will be used in this work in order to clear up the main obstacles in the teachinglearning process of geometric optics. We proceed to argue that since Newton’s approach to optics, in his Book I of Opticks, is independent of the corpuscular or undulatory nature of light, it is the most suitable for a constructivist learning environment. However, Newton’s theory must be subject to a proper didactic transposition to help overcome the referred alternative concepts. Then is described our didactic transposition in order to create knowledge to be taught using a dialogical process between students’ previous knowledge, history of optics and the desired outcomes on geometrical optics in an elementary pre-service teacher training course. Finally, we use the scheme-facet structure of knowledge both to analyse and discuss our results as well as to illuminate shortcomings that must be addressed in our next stage of the inquiry.
