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.

Determinação da condutividade do solo para agricultura: uma metodologia utilizando propagação de ondas AM

Agriculture is an essential activity to the human development, the tendency is that their need to increase according to the increase in world population. It is very important to take the maximum performance that is possible of each land without degrading it, a frequently monitoring is essential for the best performance. The purpose of this work is, nondestructively, to monitor the surface electrical conductivity of the soil in a demarcated area, as on a plantation, using low frequency radio waves. The conductivity is directly linked to the amount of water in the area and nutrients, therefore a periodic or even permanent monitoring increases significantly the efficient of the use of the soil. They will be used long-wave radio transmission or medium whose main characteristic to spread over the surface of the earth. It is possible to choose an AM radio with location, frequency and power of the transmission known or generate the signal. The studied method computes the conductivity of the ground in a straight line between two measured points, so it can be used in smaller or larger size fields. Measurements were carried out using an electromagnetic field strength analyzer. The data obtained in the measurements are processed by a numerical calculation program, in our case Matlab. It is concluded that the recommendations of the ITU (International Telecommunication Union) on the conductivity of soil in Brazil is far from reality, on some routes the recommendations indicate the use of the electrical conductivity of the soil 1 mS/m, while the measurements was found 19 mS/m. With the method described a precision farmer, once initial research for about a year, can monitor the humidity and salinity of the land, with the ability to predict the area and the most suitable time for irrigation and fertilization, making management more efficient and less expensive, while optimizing water use, natural resource increasingly precious.

Análise wavelet da variabilidade do quasar 3C 273

Discovered in 1963, 3C 273 was the second quasar identified and cataloged in the Third Cambridge Catalog for radio sources, and the first one for which emission lines were identified with a hydrogen sequence redshifted. It is the brightest quasar of the celestial sphere, the most studied, analyzed, and with a resulting abundance of data available in a vast literature. The accurate analysis of the deviations of the spectral lines of quasars provides enough information to put in evidence the variation of fundamental constants of nature and similarly the universe expansion rate. The analysis of the variability of the light curves of these bodies, and the consequent accuracy of their periodicity, is of utmost importance as it provides an efficiency of their observations, enables a greater understanding of the physical phenomena, and makes it possible to conduct spectral observations on more accurate dates (when their light curves show pronounced peaks and therefore richer spectra information). In this master’s thesis twenty eight light curves from the quasar 3C 273 are studied, covering all the electromagnetic spectrum wavebands (radio emission to gamma rays), totaling in the analysis of four light curves for each waveband. We have applied the method of Continuous Wavelet Transform using the sixth-order (!0 = 6) Morlet wavelet function, and obtained excellent results in accordance with the literature.

Aspectos técnico-interpretativos no quarteto de cordas nº 2 de Guerra-Peixe

Technical and interpretative aspects of the String Quartet No. 2 Guerra-Peixe will approach this work of a composer who is considered one of the greatest exponents of Brazilian music of the twentieth century, who developed several strands in his career as a musicologist, performer, composer, arranger radio and cinema, among others. In this work, we will see in the work in question their compositional styles, pointing sources that he has been drinking and offering elements that will subsidize technical and interpretive choices for future interpreters. After the historical context and esthetics, we will make some brief remarks about the terms performance and interpretation, to support the objective of the work, which will be the interpretation of the work. For that purpose, a comparative analysis was performed between recording of important Brazilian quartets, interviews with relevant players on the national scene and trials in rehearsals and recitals, always making a Quartet bridge with other works by the composer. Concomitantly, it was held analysis of handwritten edits by the composer, culminating with its own revised edition.

PROMOÇÃO DA CIDADANIA PELAS RÁDIOS COMUNITÁRIAS DO ABCD PAULISTA, SOB DESAFIOS E ENFRENTAMENTOS POLÍTICOS.

Esta pesquisa, intitulada “Promoção da cidadania pelas rádios comunitárias do ABCD Paulista, sob desafios e enfrentamentos políticos”, estuda 11 rádios comunitárias autorizadas pelo Ministério das Comunicações para funcionamento no Grande ABCD Paulista. Na região, cinco cidades das sete ali existentes abrigam rádios comunitárias, como Diadema (rádios “Navegantes” e “Nova Diadema”); Mauá (rádios “Mauá” e “Z”); Ribeirão Pires (rádio “Pérola da Serra”); Rio Grande da Serra (rádio “Esplanada”) e São Bernardo do Campo (rádios “Lírio dos Vales”, “Nova Riacho”, “Paraty”, “Princesa” e “Represa”). As outras duas cidades daquele território, Santo André e São Caetano do Sul, não registram emissoras comunitárias autorizadas para funcionamento. O objetivo deste estudo é o de revelar o perfil das mencionadas emissoras; a contribuição que oferecem aos processos da promoção de cidadania e inclusão social; seus problemas operacionais estruturais para sobrevivência e reações para superação. A metodologia utilizada consiste em pesquisa bibliográfica, pesquisa documental, entrevistas, visitas às rádios e estudo de programação. Estudou-se o histórico da região; os conceitos de cidadania; participação; radiodifusão comunitária e a própria trajetória das emissoras. Na sequência, houve a consulta em instituições oficiais para o conhecimento das rádios comunitárias autorizadas para funcionamento no ABCD. Posteriormente, seguiu-se a pesquisa com várias visitas de observação. As entrevistas tiveram características semiestruturadas com os radialistas e demais depoentes para este trabalho, especialistas na presente temática. Concluiu-se que existem inúmeras dificuldades que as 11 emissoras comunitárias do ABCD Paulista enfrentam para conseguir manter as rádios funcionamento. A manutenção das dificuldades se dá principalmente pela força da legislação responsável por tal segmento radiofônico comunitário, que o impede de obter apoio comercial e patrocínios.

As vogais médias tônicas: um estudo contrastivo da metafonia com base em corpus

This research analyzes the average previous stressed vowels [ε] and [e] and later [ɔ] and [o] in nominal and verbal forms in the 1st person singular and 3rd person singular and plural in the present tense, specifically the umlaut process of mid vowels /e/ and /o/, which assimilate in /ε/ and /ᴐ/ in stressed position. The general objective of this research is to describe and quantify the occurrence of umlaut and subsequently analyze in which words there is regularity or not. As specific objectives we have: i) to compile and to label an oral, spontaneous, synchronic and regional corpus, from radio programs produced in the city of Ituiutaba, Minas Gerais; ii) to describe the characteristics of the corpus to be compiled; iii) to investigate the alternating timbre of mid vowels in stressed position; iv) to identify instances of nominal and verbal umlaut of the middle vowels in stressed position; v) to describe the identified cases of nominal and verbal umlaut; vi) to analyze the probable causes for the variation of the middle vowels. To perform the proposed analysis, we have adopted as a theoretical-methodological basis multi-representational models: Phonology of Use (BYBEE, 2001) and Exemplar Theory (PIERREHUMBERT, 2001) combined with the precepts of Corpus Linguistics (BEBER SARDINHA, 2004). The corpus consisted of 16 radio programs – eight political and eight religious – from the city of Ituiutaba-MG, with recordings of about 20 to 40 minutes. We note, by means of the results generated by WordSmith Tools® software, version 6.0 (SCOTT, 2012), that the analyzed forms show little variation, which shows that the umlaut is a process already lexicalized in participants of the radio programs analyzed. We conclude that the results converge with the proposal of the Phonology of Use (BYBEE, 2001; PHILLIPS, 1984) that less frequent words that have no phonetic environment conducive to change, are changed first.
