Constructing communism in the Romanian People's Republic. Orthodoxy and state, 1948 - 49

This article analyses the ambiguous and contradictory relationship between the Orthodox Church and the communist regime during the first two years of the Romanian People's Republic. The installation of communism and the process of Stalinisation led to an unprecedented control of the church. The church was actively employed in propaganda and the regime imposed its own people in the hierarchy. On the one hand, Romanian communists followed the Soviet model regarding the place of the church in the communist state while, on the other hand, the church hierarchy adapted to the new political system by creating a theory of 'social apostolate'. Lacking popular support, the communists used the church as an instrument through which they could acquire the political support of the masses. The church thus enjoyed a favoured position in society mainly because the communists employed it in their ideological expansionism and confrontation with the West.

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.

Impact of primary networks on the performance of energy harvesting cognitive radio networks

In this paper, we investigate the effect of of the primary network on the secondary network when harvesting energy in cognitive radio in the presence of multiple power beacons and multiple secondary transmitters. In particular, the influence of the primary transmitter's transmit power on the energy harvesting secondary network is examined by studying two scenarios of primary transmitter's location, i.e., the primary transmitter's location is near to the secondary network and the primary transmitter's location is far from the secondary network. In the scenario where the primary transmitter locates near to the secondary network, although secondary transmitter can be benefit from the harvested energy from the primary transmitter, the interference caused by the primary transmitter suppresses the secondary network performance. Meanwhile, in both scenarios, despite the fact that the transmit power of the secondary transmitter can be improved by the support of powerful power beacons, the peak interference constraint at the primary receiver limits this advantage. In addition, the deployment of multiple power beacons and multiple secondary transmitters can improve the performance of the secondary network. The analytical expressions of the outage probability of the secondary network in the two scenarios are also provided and verified by numerical simulations.

Regulating integrated advertising

This chapter approaches integrated advertising as a practice that is continuous with advertising history, rather than a phenomenon associated with new technologies. Competition for technology-enabled audiences in expanding media and entertainment markets is nonetheless an important factor in the turn to integrated advertising and marketing strategies in recent years. While integrated advertising provides solutions for advertisers, it is problematic for media consumers because it is not always distinguishable from surrounding program content and clearly identifiable as advertising. It creates opportunities for advertisers to fly below the radar of citizen and consumer awareness of commercial and political influences in media content, and for this reason has been constrained by regulation. Media regulators have come to play an important role in striking a balance between public and private interests in commercial media by setting and adjudicating the limits of integrated advertising practices. This chapter looks at how broadcasting regulators have responded to the challenges of regulating integrated advertising in commercial radio in three different territories (United States, United Kingdom and Australia). It draws attention to the ways in which integrated advertising simultaneously drives innovation in media genres and forms, as well as de-regulation of the influence exercised by advertisers in commercial media content.

Reluctantly virtual : modelling copyright industry dynamics

During the evolution of the music industry, developments in the media environment have required music firms to adapt in order to survive. Changes in broadcast radio programming during the 1950s; the Compact Cassette during the 1970s; and the deregulation of media ownership during the 1990s are all examples of changes which have heavily affected the music industry. This study explores similar contemporary dynamics, examines how decision makers in the music industry perceive and make sense of the developments, and reveals how they revise their business strategies, based on their mental models of the media environment. A qualitative system dynamics model is developed in order to support the reasoning brought forward by the study. The model is empirically grounded, but is also based on previous music industry research and a theoretical platform constituted by concepts from evolutionary economics and sociology of culture. The empirical data primarily consist of 36 personal interviews with decision makers in the American, British and Swedish music industrial ecosystems. The study argues that the model which is proposed, more effectively explains contemporary music industry dynamics than music industry models presented by previous research initiatives. Supported by the model, the study is able to show how “new” media outlets make old music business models obsolete and challenge the industry’s traditional power structures. It is no longer possible to expose music at one outlet (usually broadcast radio) in the hope that it will lead to sales of the same music at another (e.g. a compact disc). The study shows that many music industry decision makers still have not embraced the new logic, and have not yet challenged their traditional mental models of the media environment. Rather, they remain focused on preserving the pivotal role held by the CD and other physical distribution technologies. Further, the study shows that while many music firms remain attached to the old models, other firms, primarily music publishers, have accepted the transformation, and have reluctantly recognised the realities of a virtualised environment.

Publiradio.net: innovación docente e investigación sobre publicidad radiofónica en el marco del EEES

La adaptación del sistema universitario catalán y español al Espacio Europeo de Educación Superior (EEES) está favoreciendo la aparición de nuevas metodologías docentes en respuesta a los requerimientos del llamado European Credit Transfer System (ECTS), una modalidad de crédito cuya principal característica consiste, como ya es ampliamente conocido, en focalizar la atención en el estudiante y, especialmente, en generar un proceso interactivo en el que el alumno se convierta en responsable activo de la adquisición de conocimientos. En el ámbito de las Ciencias de la Comunicación, una de las iniciativas más destacables de aproximación al EEES comienza en el año 2004, cuando el Departament d'Universitats, Investigació i Societat de la Informació de la Generalitat de Catalunya (DURSI) eligió a varios centros catalanes para que aplicaran de manera experimental el nuevo sistema común de créditos derivados de la Declaración de Bolonia. La Universidad Autónoma de Barcelona (UAB) fue uno de ellos, y ésta, a su vez, decidió poner en práctica la prueba piloto en la licenciatura de Publicidad y Relaciones Públicas. Es a partir de ese momento cuando los profesores del Departament de Comunicació Audiovisual i Publicitat de la UAB que forman el grupo de investigación Publiradio2 deciden poner en marcha un proyecto que, en el marco de las asignaturas de creatividad y de radio publicitaria, respondiera a las exigencias de la cultura docente en la que se inspira el crédito ECTS. Nace así Publiradio.net, un aplicativo on-line para la creación de publicidad radiofónica destinado, también, a facilitar y potenciar el aprendizaje autónomo entre los estudiantes, a fomentar, en sintonía con las apreciaciones de Aguaded, la utilización de 'técnicas y procedimientos que permitan al alumnado su análisis y uso como lenguajes propios' y a impulsar y facilitar a los estudiantes la investigación en publicidad radiofónica

O jogo das identidades como fator de mobilização político-eleitoral nas campanhas de Dilma Rousseff e Rosalba Ciarlini em 2010

Starting from the premise that we live in the society of spectacle, as proclaimed by Guy Debbord, and, in this context, the media feeds itself off of this spectacularization and constructs a culture of images and production of goods, providing templates from which the subject can identify himself/herself as being male or female, successful or unsuccessful, powerful or powerless. In other words, the culture conveyed by the media produces material for the creation of identities through which individuals insert and recognize themselves in contemporary society. Observing the election campaigns, we can see clearly that this profusion of identities is fairly explored in the advertising propaganda used by the candidates, particularly in the propaganda broadcasted on the Free Electoral Time on TV. Instigated by the explicit relation between the media and politics within the society of the spectacle, this study aims to investigate the main identities that emerge in the discursive practices of the media in the election campaigns of 2010 for president of the Republic and governor of the State of Rio Grande do Norte that had as protagonists the candidates at that moment Dilma Rousseff (PT) for president and Rosalba Ciarline (DEM) for governor. To do so, we based ourselves on the theory of Bakhtin Circle, which considers the statement as a unit of verbal communication and conceives language as a dialogical phenomena and a discursive practice and also in the conceptions of dialogical relationships, social voices and chronotope formulated by the previous mentioned theory. Still in the theoretical field, we have established an interconnection with the theories coming from the Cultural Studies (Hall, Woodward) about the identity, which conceives it as multiple, fragmented, non-fixed, so that, the subject assumes different identities, not always coherent, at different times, depending on the context in which they are approached. The research is situated in the frames of Applied Linguistics, which considers language as the center of its studies and settles on the border of an open number of areas of knowledge expanding its possibilities of investigation by means of the interdisciplinary. Our corpus consists in 20 electoral propaganda videos aired on TV during the Free Election Time in 2010 campaign; among these, 14 videos are Dilma Rousseff s propaganda and 06 videos are Rosalba Ciarline s propaganda. We seek for the purpose of the analysis to identify the identities which emerge from the discourses about the candidates in propaganda videos broadcasted in the referred campaign, as well as realize the dialogical relations established in these discourses and even if the identity construction of these subjects is located in the same axiological axis. The corpus analysis revealed that the multiple cultural identities of the candidates campaigning emerge in the discourses circulating in the electoral propaganda aired on TV such as: the identities of pioneer woman, competent, sensitive, mother, grandmother, religious. And, yet, those are changeable as the electoral demands, in other words, the need to obtain support and votes, outline a fluid identity construction about the candidate to the position in question

Predição dos campos elétricos na faixa de ondas médias em ambiente rural utilizando equações parabólicas

O Brasil está realizando testes para selecionar o padrão de transmissão digital a ser adotado. Sistemas como Digital Radio Mondiale (DRM) e Rádio de Alta Definição (HD Radio), desenvolvido apenas para frequências abaixo de 30 MHz permitem a operação com largura de banda compatível com a utilizada no país, abrindo a possibilidade de coexistência de radiodifusão analógica e digital. Para qualquer sistema a ser adotado são necessários estudos que permitem uma melhor gestão do espectro eletromagnético, que exige conhecimento real do alcance do sinal. A propagação de ondas eletromagnéticas na faixa de ondas médias (MW) é caracterizada pela dependência do campo em relação aos parâmetros elétricos do solo. Para contribuir para o planejamento e adaptação do Plano Básico de Radiodifusão em Onda Média – PMWB, a inclusão de novas estações que operam principalmente em simulcast-canal, torna-se necessário desenvolver ferramentas que permitem a avaliação das características do solo onde não fornece dados precisos, permitindo uma revisão de modelos teóricos para prever a adoção, contribuindo para a implantação do rádio digital em nosso país. Este trabalho apresenta os resultados dos ensaios de campo realizados pela ANATEL (Agência Nacional de Telecomunicações) e Radiobrás para analisar um sistema de DRM (Digital Radio Mondiale) na faixa de ondas médias. Foi gerada uma potência de 50kW, com antenas omni-direcionais operando na frequência de 980kHz e utilizando um veículo de medição para recepção fixa e móvel. Várias vias radiais foram percorridas a partir do transmissor localizado em uma área urbana e rural nos entorno da capital do Brasil, Brasília. A partir desses dados é proposto um modelo para avaliação das características elétricas do solo correspondente ao campo elétrico, através da aplicação do método de Equações Parabólicas e comprovação da eficácia do modelo proposto.
