O radiojornalismo em Portugal

A presente dissertação de mestrado incide sobre o radiojornalismo português. Para a concretizar foi feito um estudo comparativo entre as três rádios de carácter informativo de Portugal: Antena 1, Rádio Renascença e TSF. No sentido de melhor clarificar esta tese, são analisadas as grelhas de programação do programa da manhã destas estações. Está igualmente patente neste trabalho uma consideração sobre a história destas três emissoras e são evidenciados marcos que representam um verdadeiro e notório contributo para o jornalismo de rádio feito em Portugal. Para tal foi usada uma metodologia em que se fez um levantamento – a cada cinco anos - de todos os programas da manhã desde há trinta anos até hoje, no sentido de compreender as suas evoluções e comparar as diferenças das apostas de cada uma das rádios. As conclusões deste estudo apontam para o facto de as manhãs da rádio serem um período onde as notícias têm grande importância, bem como um período em que se tratam assuntos relativos à sociedade. Na Antena 1 e na TSF a inclusão de programas como “Antena Aberta” ou “Fórum TSF” faz com que a temática da sociedade, que engloba um grande número de temas e assuntos sejam a predominante. Na Rádio Renascença, apesar do seu cariz informativo, o entretenimento tem mais destaque. Uma observação notória foi também o evoluir da programação de 1985 a 2015, onde houve alterações consideráveis, tais como o aumento dos espaços dedicados a notícias e naturalmente assuntos sociais, dado que em 1985 não existia nenhum programa de opinião pública. Estes espaços foram sem dúvida, algo que marcou e fez uma mudança de paradigma no radiojornalismo português.

A reportagem nas rádios comerciais de Natal-RN

This thesis aims to investigate the space of radio reporting and production conditions in radio newscasts in commercial stations operating in modulated frequency (FM) in the city of Natal, Rio Grande do Norte. Through preliminary empirical observation, it was observed that this journalistic style (radio reportage) is hardly present in the schedule of local commercial radio stations, with a lack of in-depth news coverage. The research is based on the content broadcast in four daily radio news programs transmitted by commercial stations. It raises the hypothesis that the crisis that cuts across journalistic companies could be justified by the lack of financial funding in in-depth news reporting. The starting point for the case study (Yin, 2005) was a bibliographical research, for building a theoretical model of reference for the studied style, based on Prado (1989), Bespalhok (2006), Meditsch (2007), Lopes (2013) and Ferraretto (2014). The methodology also included listening to content broadcast during a week in the four analyzed news programs, participant observation and interviews with professionals who produce these programs. There were eight events with similar characteristics to radio reporting, all broadcast in just one of the analyzed programs. According to the interviewees, the format is rarely used because it would generate high businesses costs, which are prohibitively high for the stations. The research also inferred that besides the lack of entrepreneurial vision, there is accommodation of the professionals who could produce news stories even with little structure available. Finally, this work points out the need to invest more on local radio journalism to improve the quality of the information provided on commercial broadcasters in Natal and the training of journalism students to use radio's potential to maximum use.

New Opportunities for Development Journalism: Enlarging the Public Sphere with ICTs

The present study examines new opportunities offered by the introduction of information and communication technologies (ICTs) to enhance the development journalism practice, in order to enlarge the public sphere and empower ordinary people to participate more actively in public debate on issues affecting their development. The analysis of the achievements and challenges faced by 32 radio stations under the UNESCO project “Empowering Local Radios with ICTs” offers an overview of the introduction of ICTs in different contexts, within and among seven countries in Sub- Saharan Africa. Even though the lack of ICTs access and knowledge is still a concern in the developing world, especially in rural areas, these new tools can be adapted to each context and foster a more pluralistic and participative media in order to address people’s needs and promote social change.

La radio en el Quindío en busca de financiamiento

Investigación acerca del financiamiento de la radio en el Quindío, las consecuencias que tiene la venta de espacios en las emisoras y las presiones que hay sobre los periodistas al realizar intercambio de pauta publicitaria con sectores de la dirigencia y el poder.

Estudio sobre la contribución de la radio al envejecimiento activo. Fase incial: análisis cuantitativo de la presencia de la vejez en los magazines de radio

Este trabajo aborda la posible contribución de la radio al envejecimiento activo. La ética comunicativa actual debe tener presentes los colectivos más vulnerables de la sociedad y uno de ellos es el de la vejez. Se recogen en el artículo los principales datos demográficos sobre población mayor, cuyo crecimiento es tal que se hace necesario un cambio de paradigma a la hora de abordar estos cambios, lo que se conoce como envejecimiento activo. Se plantea que la radio, por sus peculiares características, puede contribuir a promover dicho paradigma. Pero es necesario partir de datos objetivos y el artículo concluye presentando los datos y gráficos de la investigación realizada sobre la presencia de la vejez en los magazines matinales de las cuatro emisoras más importantes del país.

College radio as coaching professional. Analysis of the relationship between the degrees and Spanish university radio

College radio is subject to constant transformation. The rise of information and communications technologies has allowed its development and modernization as well as the proliferation of new professional profiles. This research aims to analyze the connection of the Spanish university stations with the relevant qualifications. To do this, we use a comparative methodology based on examination of descriptors and specific principal subjects of degrees such as Audiovisual Communication and Journalism, although we will be using other degrees that are acquiring more responsibilities in a radio station, such as the degree in Information and Documentation. In conclusion, structural weaknesses in the university environment are observed, but future possibilities are detected as well: A college radio station is a place of convergence between the training of students from different degrees and reality itself, a versatile medium that provides the relevance of being the first professional contact of college students with the labor market.

Populations III.1 and III.2 gamma-ray bursts: constraints on the event rate for future radio and X-ray surveys

Aims. We calculate the theoretical event rate of gamma-ray bursts (GRBs) from the collapse of massive first-generation (Population III; Pop III) stars. The Pop III GRBs could be super-energetic with the isotropic energy up to E(iso) greater than or similar to 10(55-57) erg, providing a unique probe of the high-redshift Universe. Methods. We consider both the so-called Pop III.1 stars (primordial) and Pop III.2 stars (primordial but affected by radiation from other stars). We employ a semi-analytical approach that considers inhomogeneous hydrogen reionization and chemical evolution of the intergalactic medium. Results. We show that Pop III.2 GRBs occur more than 100 times more frequently than Pop III.1 GRBs, and thus should be suitable targets for future GRB missions. Interestingly, our optimistic model predicts an event rate that is already constrained by the current radio transient searches. We expect similar to 10-10(4) radio afterglows above similar to 0.3 mJy on the sky with similar to 1 year variability and mostly without GRBs (orphans), which are detectable by ALMA, EVLA, LOFAR, and SKA, while we expect to observe maximum of N < 20 GRBs per year integrated over at z > 6 for Pop III.2 and N < 0.08 per year integrated over at z > 10 for Pop III.1 with EXIST, and N < 0.2 for Pop III.2 GRBs per year integrated over at z > 6 with Swift.

Radio-frequency spectroscopy of (6)Li p-wave molecules: Towards photoemission spectroscopy of a p-wave superfluid

We study rf spectroscopy of a lithium gas with the goal to explore the possibilities for photoemission spectroscopy of a strongly interacting p-wave Fermi gas. Radio-frequency spectra of quasibound p-wave molecules and of free atoms in the vicinity of the p-wave Feshbach resonance located at 159.15G are presented. The spectra are free of detrimental final-state effects. The observed relative magnetic-field shifts of the molecular and atomic resonances confirm earlier measurements realized with direct rf association. Furthermore, evidence of molecule production by adiabatically ramping the magnetic field is observed. Finally, we propose the use of a one-dimensional optical lattice to study anisotropic superfluid gaps as most direct proof of p-wave superfluidity.

Calculating current densities and fields due to shielded bi-planar radio-frequency coils

A method for the accurate computation of the current densities produced in a wide-runged bi-planar radio-frequency coil is presented. The device has applications in magnetic resonance imaging. There is a set of opposing primary rungs, symmetrically placed on parallel planes and a similar arrangement of rungs on two parallel planes surrounding the primary serves as a shield. Current densities induced in these primary and shielding rungs are calculated to a high degree of accuracy using an integral-equation approach, combined with the inverse finite Hilbert transform. Once these densities are known, accurate electrical and magnetic fields are then computed without difficulty. Some test results are shown. The method is so rapid that it can be incorporated into optimization software. Some preliminary fields produced from optimized coils are presented.
