PUBLICIDADE, IMAGINÁRIO E IDENTIDADES NACIONAIS: O FUTEBOL E A RELIGIOSIDADE EM TEMPOS DE COPA DO MUNDO.

Este trabalho se propõe a analisar as interações entre a Publicidade, as Identidades Nacionais e o Imaginário. Para isto, foi estabelecido o objetivo de verificar a atuação da publicidade, enquanto processo comunicacional, como mediadora cultural por meio da conformação de vínculos de uma marca/produto com a representação de identidade cultural nacional de um povo, valendo-se da utilização de símbolos, mitos e de um discurso de pertencimento presentes no imaginário social. Para o alcance deste objetivo, foram assentadas as bases teóricas que estudam as temáticas: imaginário; identidades culturais e sociologia do esporte. No que diz respeito especificamente à publicidade, o estudo se concentrou nas interações da publicidade com o consumidor em que o objetivo final é estabelecer vínculos emocionais duradouros. As reflexões dos teóricos Gilbert Durand, Michel de Certeau, Stuart Hall, Raymond Williams, Eric Hobsbawm, Mário Filho, Édison Gastaldo, Kevin Roberts e Magali Cunha foram privilegiadas. A partir desse assento teórico foi possível desenvolver uma metodologia de caráter qualitativo por meio da Análise de Conteúdo em bases comparativas. A conclusão da pesquisa é que a publicidade se conecta ao imaginário social porque ela é mais um elemento da construção deste imaginário e, em função de ser um processo comunicacional, também se alimenta dele. Portanto, o publicitário (e consequentemente a publicidade) busca elementos na sua imaginação para criar e o seu repertório inclui aspectos como a identidade nacional e relações com a religiosidade popular. O produto final, midiatizado, vai fazer com que novos entendimentos sejam produzidos no imaginário social, ao mesmo tempo em que pode, também, apenas reforçar o entendimento já sedimentado acerca dessas representações.

A copa do mundo FIFA na África do Sul/2010:como foi a experiência e o que podemos aprender com ela?

Neste ensaio pretendemos problematizar algumas lógicas sociais não explícitas que se articulam ao domínio de realização da Copa do Mundo FIFA. Para tanto, privilegiamos como recorte analítico a edição de 2010 deste evento, de modo a desvelarmos algumas das retóricas e ações estratégicas que permearam o contexto de sua realização na África do Sul. Com base em dados obtidos na literatura acadêmica e mídia, buscamos apresentar que as motivações para o evento se baseavam em discursos desenvolvimentistas por parte tanto da FIFA quanto das elites locais sul-africanas visando o convencimento e apoio por parte de diferentes grupos sociais. Entretanto, as consequências não foram necessariamente aquelas prometidas, sendo essas instituições as reais beneficiadas em seus interesses econômicos e políticos. Nesse ponto, argumentamos que a sociedade brasileira pode e deve aprender com essa experiência para avaliar de forma crítica os motivos menos aparentes de sediar eventos desse porte. In this essay, we intend to discuss some social logics not explicit that articulate the domain of the FIFA World Cup. Therefore, the 2010 edition of this event is used as analytical approach to reveal some of the rhetoric and strategic actions that permeated the context of its realization. Based on data obtained in the academic literature and media, we present that the motivations for the event were based on developmental discourses by both FIFA as well as local elites South African aiming to convince different social groups and conquer their support. However, the consequences are not necessarily those promised, and these institutions were the real beneficiaries in their economic and political mutual interests. At this point, we argue that Brazilian society can and should learn from the experience of South Africa to assess critically the motives less apparent to host such events.

Metagenoma de comunidades microbianas expostas à radiação natural e a metais

Many species have specialized to live in the most varied existing environments showing the remarkable adaptability of the microbial world the most diverse physicochemical conditions. Environments exposed to natural radiation and metals are scarce around the world, presenting a microbiota still unknown. With a total number estimated between 4 and 6 x 1030 microrganisms on earth, they constitute an enormous biological and genetic pool to be explored. Metagenomic approach independent of cultivation, provides a new form to access to the potential genomic environmental samples becoming a powerful tool for the elucidation of ecological functions, metabolic profiles, as well as to identify new biomolecules. In this context, the genetic material of environmental soil and water samples from Açude Boqueirao Parelhas-RN, under the influence of natural radiation and the presence of metals, was extracted, pirosequencing and the generated sequences were analyzed by bioinformatics programs (MG-RAST and STAMP). Taxonomic comparative profiles of both samples showed high abundance of Domain Bacteria, followed by a small portion attributable to Eucaryota Domains, Archaea and Viruses. Proteobacteria, Actinobacteria and Bacterioidetes phyla showed the greater dominance in both samples. Important genera and species associated with resistance to various stressors found in region were observed. Sequences related to oxidative and heat stress, DNA replication and repair, and resistance to toxic compounds were observed, suggesting a significant relationship between the microbiota and their metabolic profile, influenced by regional environmental variables. The results of this study add valuable and unpublished data on the composition of microbial communities in these regions

Influência da radiação ionizante natural no açude do boqueirão (RN): avaliação de risco saúde/ambiente

The contamination of water bodies with toxic substances causes a decrease in water quality, representing a risk to public health. In this context, human activities are generally seen as the main sources of water degradation. However, elements found naturally in the environment can also compromise water quality. Thus, the Boqueirão‘s dam, located in the municipality of Parelhas (RN, Brazil), was chosen as area for the development of this study, as its geological region is rich in the emission of natural ionizing radiation that produces byproducts like lead and Radon. Moreover, the area has a strong human influence that enhances the risks of pollutant discharge in this body of water.Thus, the objectives of this study were centered (i) in the analysis of risk perception in the city of Parelhas (RN/Brasil) due to the use of the water from the Boqueirão Dam; and (ii) in the assessment of water quality in the Dam using methods that quantify, mainly, heavy metals and radiation levels, as well as these toxics potential of inducing mutations on genetic material. The analysis of risk perception showed that the population in the city of Parelhas can perceive a risk in using the water from the dam and that they can recognize factors that influence the water quality. Regarding the second objective, the set of data point to the contamination of the Dam by heavy metals, as well as levels of radioactive parcicles and Radon – also present in high concentrations in outdoor air and on soil. Thus, it is possible to infer that the population residing in this area is subjected to injuries caused by exposure to natural and anthropogenic contamination. Our findings corroborate with the perception of the population regarding the risks associated with the use of the Dam for several types of activities. It is expected that the information gathered in this study can substantiate activities and future researches in this semiarid region in the Rio Grande do Norte/Brazil. Also, that the set of data can enable a better understanding of the specific toxicological scenario of risk found for the population and the effect of the contamination for the biota, which aids the development of a future risk assessment and a consequent management of this local issue.

Projeto de mobilidade urbana: estudo sobre processos de integração com habitação de interesse social nas obras do PAC da COPA 2014 em Natal/RN

The public political investments of urban mobility financed by PAC of Cup 2014 have developed discussions and questions by the civil society in Brazil expecting positive results to the urban infrastructure referring to the possible human rights violation and, specially, rights of habitation related to the removing/expropriation noticed. Natal, capital of Rio Grande do Norte, is into this context, due to the urban mobility project linking North Zone of the city to the Arena das Dunas stadium, financed by the PAC of Cup 2014, named West Structural Corridor, that crosses a field of social interest and proposes almost 400 expropriations. This research analyzes how strategies and mechanisms of integration were presented between the mobility project of West Structural Corridor and the Social Interest Habitation affected by this project. We have as hypothesis those projects financed by PAC of Cup 2014/Urban Mobility to Natal/RN present many problems related to the integration of social interest to the housing project, however the National Politics of Urban Development has planned this integration. As a result we detach 3 strategies in the elaboration process about the integration of those politics: (i) integration between municipal secretaries involved in this project; (ii) urban integration of the city; and (iii) integration of public rules or public politics integrated. For each strategy were presented the main mechanisms used to establish the integration of the project. Those mechanisms, however, in this process of establishment/implementation of the empirical research, presented many contradictions and conflicts that compose problems to the integration between the mobility project and the housing area affected.

Otimização do controle do diagrama de radiação de radares de varredura para rastreio de foguetes usando o método GAMMC para o Caso Planar (GAMMC-P)

Launching centers are designed for scientific and commercial activities with aerospace vehicles. Rockets Tracking Systems (RTS) are part of the infrastructure of these centers and they are responsible for collecting and processing the data trajectory of vehicles. Generally, Parabolic Reflector Radars (PRRs) are used in RTS. However, it is possible to use radars with antenna arrays, or Phased Arrays (PAs), so called Phased Arrays Radars (PARs). Thus, the excitation signal of each radiating element of the array can be adjusted to perform electronic control of the radiation pattern in order to improve functionality and maintenance of the system. Therefore, in the implementation and reuse projects of PARs, modeling is subject to various combinations of excitation signals, producing a complex optimization problem due to the large number of available solutions. In this case, it is possible to use offline optimization methods, such as Genetic Algorithms (GAs), to calculate the problem solutions, which are stored for online applications. Hence, the Genetic Algorithm with Maximum-Minimum Crossover (GAMMC) optimization method was used to develop the GAMMC-P algorithm that optimizes the modeling step of radiation pattern control from planar PAs. Compared with a conventional crossover GA, the GAMMC has a different approach from the conventional one, because it performs the crossover of the fittest individuals with the least fit individuals in order to enhance the genetic diversity. Thus, the GAMMC prevents premature convergence, increases population fitness and reduces the processing time. Therefore, the GAMMC-P uses a reconfigurable algorithm with multiple objectives, different coding and genetic operator MMC. The test results show that GAMMC-P reached the proposed requirements for different operating conditions of a planar RAV.

Radiação-x no diagnóstico em Medicina Dentária

A radiação-x foi descoberta há mais de uma centena de anos e com o avanço tecnológico diversas formas de aplicação têm vindo a ser descobertas. A utilização constante, devido à ajuda preciosa que estes dispositivos fornecem aos clínicos de Medicina Dentária, faz com que o paciente venha, de forma crescente, a ser exposto a este tipo de radiação. Este trabalho de revisão descritiva tem como principal propósito analisar os riscos, as formas de avaliação e de proteção da radiação-x, no âmbito do seu uso em Medicina Dentária. Para o efeito, realizou-se uma revisão da literatura, tendo-se recorrido ao motor de busca EBSCO host©, utilizando as frases boleanas: (X-ray risk OR Radiography risk OR Dental x-ray risk) AND (Dental Medicine OR Oral), foi substituída a palavra risk por “evaluation” e por “protection”. Desta pesquisa resultaram 82 documentos como referências bibliográficas. Esta revisão de literatura permitiu compreender a diferença entre radiação ionizante e não ionizante, quais os dispositivos utlizados na Medicina Dentária e o seu funcionamento geral, quais as unidades de medida da radiação, quais os riscos iminentes à exposição cumulativa e quais as suas consequências biológicas, perceber de que forma a legislação Portuguesa tem evoluído em matéria de radiação ionizante, quais as diversas formas de redução da dose absorvida pelo paciente e quais as medidas de proteção para os profissionais de saúde expostos à radiação ionizante.
