A visibilidade das universidades portuguesas na web : estudo webométrico

Esta dissertação resulta de uma investigação que levou a cabo um estudo webométrico sobre a presença das universidades portuguesas na Web, avaliando a visibilidade das instituições através do cálculo de um indicador webométrico, o Web Impact Factor. A World Wide Web é, na atualidade, um dos principais meios de difusão de Informação. Os Estudos Métricos da Informação visam quantificar e avaliar a produção de Informação, objeto de estudo de disciplinas como a Infometria, a Cienciometria e a Bibliometria. Recentemente, surgiram a Cibermetria e a Webometria como novas disciplinas que estudam a produção e difusão da Informação no contexto do Ciberespaço e da World Wide Web, respetivamente. As universidades, enquanto polos privilegiados de produção e difusão de conhecimento, são o objeto de estudo natural da Webometria e a avaliação da sua presença na World Wide Web contribui para a análise do desempenho destas instituições. Para a realização deste trabalho foi adotada a metodologia proposta por Noruzi, que calcula três categorias de Web Impact Factor: o WIF Total, o WIF Revisto e o Selflink WIF. De modo a calcular estas categorias, foram recolhidos dados quantitativos de inlinks, selflinks, número total de páginas e número de páginas indexadas pelo motor de pesquisa. O motor de pesquisa utilizado foi o Altavista, tendo sido realizadas pesquisas de expressões booleanas durante o primeiro semestre de 2009. Após a recolha, os dados foram tratados estatisticamente e procedeu-se ao cálculo das categorias do WIF. Conclui-se que existe uma maior visibilidade das universidades públicas portuguesas porque obtêm melhores resultados ao nível de duas categorias do Web Impact Factor: o WIF Revisto e o Selflink WIF.

Circulation dynamics and its influence on European and Mediterranean January-April climate over the past half millennium: results and insights from instrumental data, documentary evidence and coupled climate models

We use long instrumental temperature series together with available field reconstructions of sea-level pressure (SLP) and three-dimensional climate model simulations to analyze relations between temperature anomalies and atmospheric circulation patterns over much of Europe and the Mediterranean for the late winter/early spring (January–April, JFMA) season. A Canonical Correlation Analysis (CCA) investigates interannual to interdecadal covariability between a new gridded SLP field reconstruction and seven long instrumental temperature series covering the past 250 years. We then present and discuss prominent atmospheric circulation patterns related to anomalous warm and cold JFMA conditions within different European areas spanning the period 1760–2007. Next, using a data assimilation technique, we link gridded SLP data with a climate model (EC-Bilt-Clio) for a better dynamical understanding of the relationship between large scale circulation and European climate. We thus present an alternative approach to reconstruct climate for the pre-instrumental period based on the assimilated model simulations. Furthermore, we present an independent method to extend the dynamic circulation analysis for anomalously cold European JFMA conditions back to the sixteenth century. To this end, we use documentary records that are spatially representative for the long instrumental records and derive, through modern analogs, large-scale SLP, surface temperature and precipitation fields. The skill of the analog method is tested in the virtual world of two three-dimensional climate simulations (ECHO-G and HadCM3). This endeavor offers new possibilities to both constrain climate model into a reconstruction mode (through the assimilation approach) and to better asses documentary data in a quantitative way.

The largest floods in the High Rhine basin since 1268 assessed from documentary and instrumental evidence

The magnitudes of the largest known floods of the River Rhine in Basel since 1268 were assessed using a hydraulic model drawing on a set of pre-instrumental evidence and daily hydrological measurements from 1808. The pre-instrumental evidence, consisting of flood marks and documentary data describing extreme events with the customary reference to specific landmarks, was “calibrated” by comparing it with the instrumental series for the overlapping period between the two categories of evidence (1808–1900). Summer (JJA) floods were particularly frequent in the century between 1651–1750, when precipitation was also high. Severe winter (DJF) floods have not occurred since the late 19th century despite a significant increase in winter precipitation. Six catastrophic events involving a runoff greater than 6000 m 3 s-1 are documented prior to 1700. They were initiated by spells of torrential rainfall of up to 72 h (1480 event) and preceded by long periods of substantial precipitation that saturated the soils, and/or by abundant snowmelt. All except two (1999 and 2007) of the 43 identified severe events (SEs: defined as having runoff > 5000 and < 6000 m 3 s -1) occurred prior to 1877. Not a single SE is documented from 1877 to 1998. The intermediate 121-year-long “flood disaster gap” is unique over the period since 1268. The effect of river regulations (1714 for the River Kander; 1877 for the River Aare) and the building of reservoirs in the 20th century upon peak runoff were investigated using a one-dimensional hydraulic flood-routing model. Results show that anthropogenic effects only partially account for the “flood disaster gap” suggesting that variations in climate should also be taken into account in explaining these features.

Au service du marechal?:French documentary under German occupation

Following the fall of France in June 1940 and the installation of the Vichy Regime, government set about establishing its own New Order. A reprogramming of national consciousness was attempted through an emphasis on a return to traditional values which was disseminated in various fora. Despite publications on divers aspects of Vichy's propaganda machine, work on film production of the period has merely touched on mainstream documentary without further analysis. Such a lacuna appears inexplicable in light of the production of 550 or so documentaries between 1940 and 1944, especially in view of a 1948 comment by the film writer Roger Régent that documentary in many ways provided a focal point for the regime's wishes for "moralisation collective". This thesis sets out the first steps of a new evaluation of the role of documentary during the Occupation. After an overview of the changes to the industry and the ideological framework of the Révolution nationale, the thesis discusses theories of propaganda together with direct examples of Vichy propaganda documentary. The 'control' thus established is then applied to an examination of the 'Arts, Sciences, Voyages' series of documentary screenings (1941-43) and the Premier congrès du film documentaire (1943), tracing thematic and ideological consonances and evaluating the use of documentary film of the Occupation in the Service of the Marshal.

Construction of the Cognitive Dimension of the Scientific Literacy in the Students through the Costa Rican Biological Sciences Olympics

This research recognizes the cognitive contributions to the students participating in the Third Costa Rican Biological Sciences Olympics that will define the advancement and strengthening in the construction of its conceptual dimension in the scientific literacy.  This paper is based, mainly, on qualitative approach techniques (ethnographic design:  case study); however, some data are interpreted through quantitative methodologies (descriptive design with an explanatory and exploratory touch) for the analysis of a sample of 54 high school students, finalists in the category A of the Olympics, through the use of tools such as a documentary study and a survey, in July 2009.  The information generated was analyzed using elements of inferential and descriptive statistics, figures and histograms.  It was proved that there is a better cognitive management in the topics assessed, an increase in the students’ academic performance as the tests are applied, a commitment for the academic update supported by the development of several tasks for previous preparation, curriculum contributions unprecedented based on our sample, a consent to optimize student’s knowledge about Biology, which will allow the application of scientific notions to diversify and renew the knowledge, according to what is established in the principles of scientific literacy.

[the Teaching Of Social Sciences In Health: Between Practice And Theory].

The models of teaching social sciences and clinical practice are insufficient for the needs of practical-reflective teaching of social sciences applied to health. The scope of this article is to reflect on the challenges and perspectives of social science education for health professionals. In the 1950s the important movement bringing together social sciences and the field of health began, however weak credentials still prevail. This is due to the low professional status of social scientists in health and the ill-defined position of the social sciences professionals in the health field. It is also due to the scant importance attributed by students to the social sciences, the small number of professionals and the colonization of the social sciences by the biomedical culture in the health field. Thus, the professionals of social sciences applied to health are also faced with the need to build an identity, even after six decades of their presence in the field of health. This is because their ambivalent status has established them as a partial, incomplete and virtual presence, requiring a complex survival strategy in the nebulous area between social sciences and health.

The notion of structure and the information records of the documentary systems

Assuming as a starting point the acknowledge that the principles and methods used to build and manage the documentary systems are disperse and lack systematization, this study hypothesizes that the notion of structure, when assuming mutual relationships among its elements, promotes more organical systems and assures better quality and consistency in the retrieval of information concerning users` matters. Accordingly, it aims to explore the fundamentals about the records of information and documentary systems, starting from the notion of structure. In order to achieve that, it presents basic concepts and relative matters to documentary systems and information records. Next to this, it lists the theoretical subsides over the notion of structure, studied by Benveniste, Ferrater Mora, Levi-Strauss, Lopes, Penalver Simo, Saussure, apart from Ducrot, Favero and Koch. Appropriations that have already been done by Paul Otlet, Garcia Gutierrez and Moreiro Gonzalez. In Documentation come as a further topic. It concludes that the adopted notion of structure to make explicit a hypothesis of real systematization achieves more organical systems, as well as it grants pedagogical reference to the documentary tasks.
