Atitudes relativas a meios de comunicação: um estudo exploratório sobre o Wap

The new economy stimulated by the bigger Internet participation as an interaction mean between people and business has been changing the companies¿ management routine. Nowadays, Internet access goes through telephones, in the houses and offices, or through nets of the Intranet kind, with the users in their working settings. The Internet personal access added, with mobility, surely will bring changes to our contacting form to the outside world as well as it will create a possibility of giving the customers a bigger variety of products and services. The present study aims are: (i) to verify the customers behaviours related to this new media, presented in the mobiles digital screens; (ii) to explore some of their main features, and (iii) to compare them with the other media features, as the radio and the TV ones. The applied research methodology was the data collecting through phone interviews. To obtain a Confidence Interval of 95%, 470 WAP, Internet, radio and TV current users¿ answers were gotten. To compare the media, the Fishbein multi-attributes model was used what possibilities to form comparative scores of the attributes built for the research. To mark the discussion concerning the public behaviour related to the differentiated use of the mentioned media out, the study produced uses the McLuhan theoretical reference (1969), specially concerning to his theoretical building, denominated hot and cold means. But this referential theoretic mark could not be supported by the accomplished quantitative study result. The comparison of built attribute scores averages has differentiated the hot media WAP, like radio, as well as the cold media one, like TV. This way, showing that the access new technology appearance, WAP, not only enlarges the Internet use, but also appoints to a new theoretic classification possibility to this new media. The accomplished quantitative research revealed that, through the user point of view, the ¿Contents¿ category is considered as one of the most important WAP aspects. The TV and the radio received significantly lower grades in this subject. The public considers that is important that the WAP information is ¿trustworthy¿, ¿easy¿ to find, ¿available¿, ¿sufficient¿ and that attends the ¿urgency¿ expected by the user. It was observed that the WAP score ¿emotion¿ is inferior to the radio and TV and superior to the Internet ones. But, the differences found are not significant. Considering the low score of importance given to the attributes group ¿emotion¿, is not recommended the WAP use as media when the emotional users aspects are wanted to be reached.

O rádio como espaço de visibilidade política : (governo da Frente Popular em Porto Alegre 1989/1990

Esta é uma pesquisa sobre mídia e política que aborda o uso do rádio pelo governo da Frente Popular em Porto Alegre, no período entre abril de 1989 e setembro de 1990. É um estudo de caso que trata do sistema de monitoração de rádio adotado pelo governo da Frente Popular em seis emissoras de rádio ( Gaúcha, Guaíba, Farroupilha, Princesa, Bandeirantes e Pampa) durante 24 horas. Defende-se a tese de que o governo da Frente Popular, em Porto Alegre, ao responder aos ouvintes, apropriou-se de um lugar específico da mídia para dar visibilidade ao seu projeto político de esquerda constituindo um novo cenário da disputa política. Com esta estratégia de responder a interpelação dos ouvintes, a Frente Popular pautou a mídia e provocou uma alteração nos critérios de noticiabilidade no rádio ao mesmo tempo em que estabeleceu um controle da programação das emissoras. Os objetivos do estudo são verificar se a estratégia de Comunicação da Prefeitura Municipal de Porto Alegre de controlar as demandas dos cidadãos, através do rádio, resulta em créditos político; entender como, em uma sociedade dominada pela informação, produto de grandes empresas de comunicação, consegue ser seduzida pela estratégia política de um governo; compreender a eficácia do rádio como instrumento de uso político de governos democráticos; reafirmar que a pesquisa de campo, que leva em conta a prática e a observação dos cidadãos comuns e seu cotidiano, é a base para todo e qualquer estudo sobre a ação da comunicação, especialmente, do jornalismo na sociedade. O governo da Frente Popular através das diferentes secretarias e autarquias respondia aos ouvintes, prometendo executar o serviço no espaço da própria emissora que havia veiculado a reclamação. Esta trama entre rádio, ouvinte e governo resulta no fortalecimento do projeto político da Frente Popular.

O Rádio na formação musical : um estudo sobre as idéias e funções pedagógico-musicais do programa Clube do Guri(1950-1966)

Este estudo investigou a contribuição do programa de rádio Clube do Guri na formação musical de crianças e jovens que dele participavam, buscando compreender qual era a importância do programa para essas pessoas, como se dava a participação musical de jovens e crianças no programa, qual era o formato, o conteúdo e a concepção do programa, quais suas funções pedagógico-musicais, bem como a relação do programa com a escola. Para a realização desta pesquisa foi utilizado a metodologia da História Oral, entrevistando dois integrantes da equipe do Clube do Guri e cinco participantes que atuaram no programa. O Clube do Guri, foi veiculado na rádio Farroupilha, em Porto Alegre, entre 1950 e 1966, sendo um dos maiores sucessos do rádio gaúcho. Os participantes do programa eram crianças e jovens entre cinco e quinze anos de idade, que se apresentavam cantando, declamando, dançando, fazendo locução ou tocando um instrumento. Tomando-se como referência as teorias sobre aprendizagem através dos meios de comunicação (Schmidt, 2001; Steinberg, 1997; Fischer, 1997, 2001; Braga e Calazans, 2001; Nanni, 2000; Souza, 2000; e Thompson, 1998), o estudo evidenciou que o programa Clube do Guri teve um papel preponderante na formação musical de crianças e jovens que dele participaram, propiciando a profissionalização de muitos integrantes.

O consultório sentimental de madame Danjou: experiências femininas nas ondas do rádio

Deocélia Vianna apresentou por um curto período, de 1952 a 1953, uma atração radiofônica intitulada Madame Danjou, que consistia em um programa de consultório sentimental, para o qual as ouvintes encaminhavam suas dúvidas através de cartas. Para as mulheres, o hábito de escrever cartas e diários não representou, ao longo dos anos, apenas uma peculiaridade feminina, e sim a possibilidade de expressão. Assim, em nossa análise sobre as demandas encaminhadas ao programa Madame Danjou, buscamos identificar elementos que nos permitam qualificar tanto as missivistas quanto a própria radialista como integrantes de um contexto específico, sem, no entanto, ignorar suas particularidades. Para tanto, consideramos o programa radiofônico como espaço de reflexão e sociabilidade para esses agentes sociais, devido ao fluxo de perguntas e respostas que o caracteriza. Antes, porém, não podemos perder de vista a trajetória particular de Deocélia Vianna, bem como as especificidades desse tipo de programa para compreendermos a outra ponta do diálogo que se estabelece: os conselhos. Também privilegiaremos a sua dimensão normatizadora, visto que tais conselhos eram direcionados para a remediação de conflitos do âmbito privado, via a adequação de determinados comportamentos.

Avaliação da publicidade de medicamentos veiculada nas principais emissoras de rádio de Natal-RN

Drugs advertising is one of the most important marketing resources used by the pharmaceutical industry to induce people to buy these products although they do not have the real necessity to use them. The purpose of this article is to evaluate drugs advertisings transmitted on radio stations in Natal/RN, from October 2007 to September 2008. Were collected 228 advertising pieces, where, 21 were different among themselves and corresponded to 15 drugs. The results showed that 73,3% of the drugs ads were announced on AM station and 26,7% on FM station. The majority of the drugs were constituted of analgesics (26%), following by antiacids, vitamins, phitotherapics (13% each). The legal analysis showed that each advertising had some kind of infraction. The omission of the registration number happened in each advertising, following by the totally lack of contraindications (95,2%) and contraindications DCB/DCI (76,2%). In 42,9% advertisements were observed the relation between drugs use and physique/intellectual/emotional/sexual performance and/or beauty and 33% of them had abusive exploration of illnesses. The obligatory warning was omitted in 28,6% and the offer of financial bonus happened in 9,5% cases. The content analysis demonstrated that the most persuasion and convincing elements observed were indicatives of consumption appeal (34,2%). The study indicates the necessity of the topic drugs advertisements to be treated in a wide context, that is, to be discussed as a public health concern. Although the advertising regulation and inspection is the State responsibility , this should be shared with the advertising agency, pharmaceutical industry and media. Furthermore, it is indispensable to inform and to conscience the population of their rights in such mistaken situation

Podcast na educação brasileira: natureza, potencialidades e implicações de uma tecnologia da comunicação

This thesis aims to build a panoramic analysis with the intention of providing the theoretical initial a thought articulated educational of podcast, a technology orality distributed demand. This joint search considering the various spheres that educational technology in Brazilian use, both in school and non-school contexts, including scenarios and distance. This study unites questions addressed piecemeal in the area to new perspectives about the podcast, in order to characterize its nature, examining such technology from a perspective of educational technology itself, as well as unveiling its main potentials and implications. The survey was conducted from the combined use of quantitative and qualitative categories, with emphasis on the last one. The method of participant observation was followed by immersion of the researcher in the audience groups of Brazilians podcasts. Data collection with sources held in non-school contexts, from a look at targeted interactions given the blogs of Brazilian productions, as well as from open-ended interviews with producers - made online - besides giving themselves from the hearing itself about five hundred podcasts of Brazil. In the school context, the research focused on a literature review of the literature of the study area. Were added to the corpus described statistics derived mainly from "Podpesquisa 2009," Numerical major survey on the use of podcasts in Brazil. The articulation and analysis of the collected data, we used the concept of Education Paulo Freire (1971, 1987), so that, understanding it as synonymous to communication - understood this concept in Freire - were able to reveal the various ramifications educational podcast Brazilian atmosphere permeated by a dialogic between its participants. Moreover, the ideas of Célestin Freinet (1998) about the cooperation, while education practice, conducted the analyzes productive technology addressed in this work. The philosophical thought of Andrew Feenberg (2003) on the notion of "technologies" buoyed technological design elaborate. Such consideration provided the foundation for the reflections and proposals offered in this study, which, in the characterization of the oral nature of the podcast - especially their version for the deaf - appropriated the placements Luis Antonio Marcuschi (2001) about the relationship between orality and writing. In addition to these references, several other authors were considered, dealing with issues that pervade the theme here delimited, contemplating discussions on topics such as educational interest, online production, inclusive education, among other aspects. At the end, there was the podcast as a technology, while still reproducing social asymmetries Brazilian fairly directed at promoting mitigations hierarchical and open production in digital orality promotes. In view of its technical and educational implications in national use, the technology study has revealed potential relevant to the sophistication of teaching practices with orality, in various contexts, and proved adequate to serve as a motto to the revision of school practices, to even the very role of the school. This, by the prospects unveiled here, can, through the podcast, mitigate their questions reproductivist to constitute themselves as under privileged communication, boosted by critical rescue and sophistication of management through the most basic education component: speech

Desenvolvimento de um protocolo de comunicação para automação de subestações móveis via satélite

One of the most important decisions to turn a substation automatic and no attended it relates to the communication media between this substation and Operation Center. Generally energy companies uses radio or optic fiber, depending of distances and infrastructure of each situation. This rule applies to common substations. Mobile substations are a particular case, therefore they are conceived for use at provisional situations, emergencies, preventive or corrective maintenance. Thus the telecommunication solution used at common substations are not applied so easily to mobile substations, due absence of infrastructure (media) or difficulty to insert the mobile substation data in existing automation network not long. The ideal media must supply covering in a great geographic area to satisfy presented requirements. The implantation costs of this big infrastructure are expensive, however a existing operator may be used. Two services that fulfill that requirements are satellite and cellular telephony. This work presents a solution for automation of mobile substations through satellite. It was successfully implanted at a brazilian electric energy concessionaire named COSERN. The operation became transparent to operators. Other gotten benefits had been operational security, quality in the supply of electric energy and costs reduction. The project presented is a new solution, designed to substations and general applications where few data should be transmitted, but there is difficulties in relation to the media. Despite the satellite having been used, the same resulted can be gotten using celullar telephony, through Short Messages or packet networks as GPRS or EDGE.

Classificação Automática de Modulação Digital com uso de Correntropia para Ambientes de Rádio Cognitivo

Modern wireless systems employ adaptive techniques to provide high throughput while observing desired coverage, Quality of Service (QoS) and capacity. An alternative to further enhance data rate is to apply cognitive radio concepts, where a system is able to exploit unused spectrum on existing licensed bands by sensing the spectrum and opportunistically access unused portions. Techniques like Automatic Modulation Classification (AMC) could help or be vital for such scenarios. Usually, AMC implementations rely on some form of signal pre-processing, which may introduce a high computational cost or make assumptions about the received signal which may not hold (e.g. Gaussianity of noise). This work proposes a new method to perform AMC which uses a similarity measure from the Information Theoretic Learning (ITL) framework, known as correntropy coefficient. It is capable of extracting similarity measurements over a pair of random processes using higher order statistics, yielding in better similarity estimations than by using e.g. correlation coefficient. Experiments carried out by means of computer simulation show that the technique proposed in this paper presents a high rate success in classification of digital modulation, even in the presence of additive white gaussian noise (AWGN)

Interação no rádio: a participação do ouvinte no programa debates do povo

The radio is just not seen as conveying information, but a media able to establish ways that generate certain direction. We see an inclusion of the listener in the construction of programs, is exposing their life stories, commenting on facts, answering questions, choosing subjects and participating in some form of radio programming. This insertion of the listener in radio programs is generally thought of as a constituent element of the message. This study aims to analyze the participation of the listener and the forms of interaction in the " Debates of the People" that thirty- past two years is the schedule for CBN Fortaleza. The investigation was conducted through observation in studio, interview, transcription, content analysis and association analysis. This is a qualitative and quantitative research while. We found that the listeners of the program had no acceptance of interactive tools such as the Internet and social networks to make their holdings. In clipping analyzed, we noted that the participation of the listener was selected according to their relationship and proximity to the topic discussed. Also detected that the opinion is superior to the listener questions on the topic. The presenter has the function to put the questions in the listener program. Among the public comments are questions and opinions on the subject and speaks of the debaters. Among the authors, use Barbosa (2009 ), Ferraretto (2007 ), Lopez (2010 ), Ortriwano (2001 ), Peruzzo (2004 ), Prata (2009 ), Primo (2006 ), Thompson (2009 ), among others

Por uma pedagogia do oprimido midiático: meios de comunicação e suas intervenções na escola

En este trabajo nos ocupamos de la convergencia de la fotografía, el vídeo y la música, intermediado por una estación de radio en la escuela, instalada en la escuela Municipal de Djalma Maranhão, Natal, Rio Grande do Norte, en una clase de 5º año de jóvenes y adultos en el año escolar 2007. Se analizan las intervenciones causados los que participan en la vida escolar, a partir de las actividades realizadas por ellos, en la producción de programas de radio. Los procedimientos metodológicos sobre la base de la etnometodologia (COULON, 1995a, 1995b), en la investigación cualitativa (BOGDAN, BIKLEN, 1999, DENZIN y LINCOLN, 2006), participante como observador (MAY, 2004) y la investigación-acción (THIOLLENT, 1992). La comprensión de Paulo Freire en la comunicación e la educación es nuestro principal referente teórico. Los experimentos citados en los medios de comunicación revelaron varias posibilidades de mejora en la enseñanza y el aprendizaje, como el aumento de la autoestima de los estudiantes, social y de inclusión educativa de personas con discapacidad, disminución de la timidez y facilitar la comunicación entre los sujetos, lo que permite el diálogo entre ellos, intervino en sus relaciones sociales, más allá de los límites de la escuela. La investigación confirma, entonces, que la comunicación y la educación son parte de la misma naturaleza
