Informative Radio Models in Brazil: The All-News Networks

This study analyzes the particularities of Brazilian radio networks that adopt the all-news format and briefly presents the main national and international experiences for the implementation of the model and its conceptualization. Besides the bibliographic review, we use the multiple-case study, analyzing as the empirical objects CBN and BandNews FM networks. Also, we apply methodological procedures of systematic non-participant observation, supplemented by interviews and surveys. We conclude that the different all-news programming models and network organizations influence the processes of production, information structure, broadcasting language, and therefore the stations' profile. © 2011 Copyright Taylor and Francis Group, LLC.

Modernidade e integração na Amazônia: "intelligentsia" e "broadcasting" no entre guerras, 1923 -1937

Modernidade e integração na região chamada Amazônia, vez ou outra, sempre ouvimos na mídia, nos meios intelectuais, entre políticos das mais variadas tendências, do Norte e de outras regiões do país, e surgem questionamentos sobre qual o melhor caminho para a Amazônia. Projetos e ideologias foram criados, normalmente girando em torno das possibilidades de modernidade e integração para a região, há muito considerada reserva de lendas e minérios, o reino da floresta e da "planície", espaço isolado, distante, verdadeiro "vazio" de "éden tropical" ou "inferno verde". Desde os embates na Colônia e no Império sobre integrar ou separar do poder central até aos grandes projetos nos anos de 1970, a intelligentsia local e os meios de comunicação manifestaram ponto de vistas e assumiram, em muitos casos, posicionamentos políticos, principalmente a partir dos séculos XIX e XX. Tentei entrar um pouco nesse debate, reportando-me às primeiras décadas do século XX, e encontrando nesse passado, personagens que espelham os novos atores do presente: os intelectuais e o meio de comunicação mais moderno do entre guerras, ao lado do cinema, o rádio.

Educational Television Broadcasting in Germany: Prevailing Practices, Existing Challenges and Adoptable Policies

Television is widely used for educational purposes but has still not achieved its fullest potential neither in developed nor in developing countries. This worldwide under performance invite experts and academics to join hands to search causes and provide suggestions to make television a better and popular learning tool. Guided by this philosophy, the present paper analyzes the educational television broadcasting in Germany from different perspectives. The focus of analysis includes measures and practices adopted by German institutions/broadcasters to promote educational television. Besides dealing with these issues, the paper discusses existing challenges and suggests best adoptable educational television broadcasting polices from Germany to promote educational television in global perspectives.

Exposure to Radio-Frequency Electromagnetic Fields From Broadcast Transmitters and Risk of Childhood Cancer: A Census-based Cohort Study

We investigated the association between exposure to radio-frequency electromagnetic fields (RF-EMFs) from broadcast transmitters and childhood cancer. First, we conducted a time-to-event analysis including children under age 16 years living in Switzerland on December 5, 2000. Follow-up lasted until December 31, 2008. Second, all children living in Switzerland for some time between 1985 and 2008 were included in an incidence density cohort. RF-EMF exposure from broadcast transmitters was modeled. Based on 997 cancer cases, adjusted hazard ratios in the time-to-event analysis for the highest exposure category (>0.2 V/m) as compared with the reference category (<0.05 V/m) were 1.03 (95% confidence interval (CI): 0.74, 1.43) for all cancers, 0.55 (95% CI: 0.26, 1.19) for childhood leukemia, and 1.68 (95% CI: 0.98, 2.91) for childhood central nervous system (CNS) tumors. Results of the incidence density analysis, based on 4,246 cancer cases, were similar for all types of cancer and leukemia but did not indicate a CNS tumor risk (incidence rate ratio = 1.03, 95% CI: 0.73, 1.46). This large census-based cohort study did not suggest an association between predicted RF-EMF exposure from broadcasting and childhood leukemia. Results for CNS tumors were less consistent, but the most comprehensive analysis did not suggest an association.

Desarrollo de la radio en el marco de las rivalidades político-militares de principios del siglo XX

A lo largo de este proyecto, se analizarán los comienzos de la radio en las primeras décadas del siglo XX, teniendo como objetivo describir el desarrollo científico-tecnológico y las rivalidades político-militares de las potencias europeas de Reino Unido y Alemania. En primer lugar se verán los precursores de la radio que existían anteriormente al surgimiento de la radiotelegrafía como la telegrafía óptica, la telegrafía eléctrica o el teléfono. Al igual que los primeros investigadores, como James Clerk Maxwell o Heinrich Rudolf Hertz, gracias a los cuales el origen de la radio fue posible. También se analizará el contexto histórico-político de Reino Unido y Alemania donde se muestran las características de las dos grandes potencias del momento, el Imperio Británico y el Imperio Alemán. Además, la cada vez mayor importancia de la telegrafía sin hilos, hará necesaria una organización internacional, dando lugar a las Conferencias Internacionales de Radiotelegrafía y que enfrentarán a estas dos potencias por defender sus intereses. Guillermo Marconi, por parte de Reino Unido, y Telefunken, por parte de Alemania, serán las principales marcas comerciales de radiotelegrafía, no solo en sus respectivos países, sino también en el resto del mundo. Entre ambas compañías se verán las rivalidades por la incesante lucha de patentes, el desarrollo tecnológico y el control de los mercados. También se tratará el enfrentamiento directo que se produjo en la Primera Guerra Mundial, donde la radio jugaría un papel fundamental. Por último, se analizarán los comienzos de la radiodifusión en la segunda década del siglo XX, donde la radio ya estaba consolidada como uno de los medios de comunicación más importante de la época, capaz de llegar a todos los rincones del planeta y perfectamente integrada en la sociedad del momento. ABSTRACT. Throughout this project, it will be analyzed the beginning of the radio in the first decades of the XX century, having as goal to describe the scientific-technological development and the political-militaries opponents of the European’s countries, United kingdom and Germany. Firstly, it will be shown the radio’s precursors before the origin of the wireless telegraphy, like: optical telegraphy, electric telegraphy or telephone. Moreover, it will show the first researchers like: Clerk Maxwell or Heinrich Hertz, thanks to them, the origin of the radio was possible. In addition, it will analyze the historical-political context of United Kingdom and Germany, where it is shown the main features of the Britain Empire and the German Empire. Moreover, the importance of the telegraphy without wire will make necessary and international organization, resulting the International Conferences of Wireless Telegraphy and it will put together these main countries in order to protect their interests. Guglielmo Marconi, by United Kingdom, and Telefunken, by Germany, they will be the main commercials brand of the wireless telegraphy, not only in their countries, but also in all over the world. Between both companies will be seen the main competitions for their patens, the technology development and the market’s control. Moreover, it will be dealt the direct conflict in the First World of War, where the radio has a fundamental role. Finally, it will be analyze the beginning of the wireless broadcasting in the second decade of the XX century, where the radio was established as one of the most important media of the age, able to arrive at every places of the world and it was perfectly integrated in the society of that moment.

Community broadcasting and the enclosure of the public sphere

One of the normative tenets of the Habermasian public sphere is that it should be an open and universally accessible forum. In Australia, one way of achieving this is the provision for community broadcasting in the Broadcasting Services Act. A closer examination of community broadcasting, however, suggests practices that contradict the idea of an open and accessible public sphere. Community broadcasting organizations regulate access to their media assets through a combination of formal and informal structures. This suggests that the public sphere can be understood as a resource, and that community broadcasting organizations can be analysed as ‘commons regimes’. This approach reveals a fundamental paradox inherent in the public sphere: access, participation and the quality of discourse in the public sphere are connected to its enclosure, which limits membership and participation through a system of rules and norms that govern the conduct of a group. By accepting the view that a public sphere is governed by property rights, it follows that an open and universally accessible public sphere is neither possible nor desirable.
