A construção da notícia em estado de graça: o processo de agenda-building nos primeiros 100 dias do XXI Governo Constitucional

Tomando como ponto de partida a análise da totalidade de notícias publicadas nos primeiros 100 dias do XXI Governo Constitucional da República Portuguesa em quatro jornais diários nacionais, o presente estudo procura perceber, num primeiro ponto, se este Governo gozou o tradicional estado de graça, para depois apurar se o processo de construção de agenda tem influência sobre o ângulo da peça noticiosa. A análise realizada permite concluir que o Governo em questão gozou do tradicional estado de graça – cerca de metade das notícias publicadas são favoráveis ao executivo. Para além disso, verifica-se uma correlação, ainda que moderada, entre o tipo de agendamento que deu origem às notícias e o respetivo ângulo, o que significa que o tipo de agendamento influencia o produto final

Crise dos refugiados no Twier: As representações sociais e o papel dos influenciadores da rede

O papel dos média na criação de representações sociais é especialmente relevante quando veiculam mensagens sobre uma realidade distante do cidadão, como a crise dos refugiados. Por isso, este estudo visa compreender até que ponto os meios de comunicação influenciam as representações sobre os refugiados. Foi feita uma análise a 1042 tweets, entre os quais surgem mais mensagens com opiniões favoráveis do que desfavoráveis e um grande número de opiniões sobre um assunto em agenda na semana analisada. Por outro lado, no Twitter, o debate é feito em torno dos média e há uma elevada utilização da partilha rápida. Além disso, é clara a existência de gatewatchers, ou seja, de atores desconhecidos capazes de influenciar a rede

Gaia Early Data Release 3: Structure and properties of the Magellanic Clouds

We compare the Gaia DR2 and Gaia EDR3 performances in the study of the Magellanic Clouds and show the clear improvements in precision and accuracy in the new release. We also show that the systematics still present in the data make the determination of the 3D geometry of the LMC a difficult endeavour; this is at the very limit of the usefulness of the Gaia EDR3 astrometry, but it may become feasible with the use of additional external data. We derive radial and tangential velocity maps and global profiles for the LMC for the several subsamples we defined. To our knowledge, this is the first time that the two planar components of the ordered and random motions are derived for multiple stellar evolutionary phases in a galactic disc outside the Milky Way, showing the differences between younger and older phases. We also analyse the spatial structure and motions in the central region, the bar, and the disc, providing new insights into features and kinematics. Finally, we show that the Gaia EDR3 data allows clearly resolving the Magellanic Bridge, and we trace the density and velocity flow of the stars from the SMC towards the LMC not only globally, but also separately for young and evolved populations. This allows us to confirm an evolved population in the Bridge that is slightly shift from the younger population. Additionally, we were able to study the outskirts of both Magellanic Clouds, in which we detected some well-known features and indications of new ones

The Gaia mission

Gaia is a cornerstone mission in the science programme of the EuropeanSpace Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was changed to a direct-imaging approach. Both the spacecraft and the payload were built by European industry. The involvement of the scientific community focusses on data processing for which the international Gaia Data Processing and Analysis Consortium (DPAC) was selected in 2007. Gaia was launched on 19 December 2013 and arrived at its operating point, the second Lagrange point of the Sun-Earth-Moon system, a few weeks later. The commissioning of the spacecraft and payload was completed on 19 July 2014. The nominal five-year mission started with four weeks of special, ecliptic-pole scanning and subsequently transferred into full-sky scanning mode. We recall the scientific goals of Gaia and give a description of the as-built spacecraft that is currently (mid-2016) being operated to achieve these goals. We pay special attention to the payload module, the performance of which is closely related to the scientific performance of the mission. We provide a summary of the commissioning activities and findings, followed by a description of the routine operational mode. We summarise scientific performance estimates on the basis of in-orbit operations. Several intermediate Gaia data releases are planned and the data can be retrieved from the Gaia Archive, which is available through the Gaia home page. http://www.cosmos.esa.int/gai

The World in the news: comparing the published news in the Foreign section in print and online versions of Jornal de Notícias

Relatório de estágio de mestrado em Ciências da Comunicação (área de especialização em Informação e Jornalismo)A produção noticiosa para duas plataformas – para a Web e para a versão impressa – não é igual. Ao longo dos três meses do estágio no Jornal de Notícias (secção Mundo) reparei nas diferenças nos processos de seleção das notícias e também na sua produção. Foi assim que nasceu a questão da presente investigação: existe ou não alguma diferença na seleção das notícias internacionais para diferentes plataformas de publicação. No presente trabalho, as notícias da secção Mundo da versão impressa do Jornal de Notícias, foram analisadas e comparadas com as notícias publicadas pela mesma secção, mas no site do jornal. Através da análise, além dos critérios de noticiabilidade, procurou-se estudar, ainda, as temáticas e os países mais abordados nesta secção, mas também o peso das hard e soft news. Por serem plataformas com características diferentes, foram também analisadas algumas das caraterísticas do jornalismo online (abundância, hipertextualidade e multimodalidade). se estão, de alguma forma, relacionadas com os critérios de noticiabilidade, a localização dos acontecimentos e a temática das notícias.The news production for two platforms - for the Web and the print version - is not the same. During my three months’ internship on Jornal de Notícias (Foreign section) I have noticed differences in news selection and production processes. This is how the question of the present investigation was born: is there or not any difference in the selection of international news for different publishing platforms? On the present work, I have analysed and compared the news published on the Foreign section of the printed version with the news published by the same section, but on the newspaper's website. Through the analysis, in addition to the newsworthiness criteria, I have studied not only the themes and the most covered countries on these sections, but also the weight of hard and soft news on it. Because they are platforms with different characteristics, some of the online journalism features (abundance, hypertextuality and multimodality) have also been analysed to check if these characteristics are in some way related to the criteria of news, the location of events and the news theme of the analysed articles

Multimodality Imaging in Right Heart Tumors: Proposed Algorithm towards an Appropriate Diagnosis

A right heart tumor can be identified by transthoracic echocardiography during a routine examination or due to cardiac symptoms. The first step is the assessment by echocardiography, with its multiple techniques, and the obtained information must be judged in a clinical and biological context. The second step comprises one, sometimes even two, of the more complex modality imaging methods. The choice is driven not only by the advantages of each imaging technique but also by local expertise or the preferred imaging modality in the center. This step is followed by staging, follow-up, and/or imaging-guided excision or biopsy, which is performed in selected cases in order to obtain anatomopathological confirmation. In the presence of features suggestive of malignancy or causing hemodynamic impairment, a transvenous biopsy is essential before the more complex imaging modalities (which are still relevant in the staging process). Using a structured imaging approach, it is possible to reach an appropriate diagnosis without a biopsy. Frequently, these imaging techniques have a complementary role, so an integrated imaging approach is recommended. This proposed algorithm for appropriate diagnosis of right heart tumors could serve as a practical guide for clinicians (not only imaging specialists)

Mutations of calcium-sensing receptor gene: two novel mutations and overview of impact on calcium homeostasis.

Genetic disorders of calcium metabolism arise in a familial or sporadic setting. The calcium-sensing receptor (CASR) plays a key role in maintaining calcium homeostasis and study of the CASR gene can be clinically useful in determining etiology and appropriate therapeutic approaches. We report two cases of novel CASR gene mutations that illustrate the varying clinical presentations and discuss these in terms of the current understanding of CASR function.Case ReportsJournal ArticleSCOPUS: ar.jinfo:eu-repo/semantics/publishe
