O desafio da pesquisa em folkcomunicação: cartografia 1998-2011

Este trabalho é resultado de uma pesquisa realizada, inicialmente, sob a supervisão da Cátedra UNESCO de Comunicação e posteriormente complementada e atualizada para essa publicação. O projeto fez primeiro inventário das pesquisas apresentadas em anais de eventos que tratam da temática e dos conceitos da Folkcomunicação, apontando sua importância nos cenários comunicacional e cultural do Brasil. Tratou-se de evidenciar a produção de um conjunto de pesquisadores, representantes de várias regiões do País, que buscam divulgar e estimular os estudos no campo da Folkcomunicação e da cultura popular. Utilizando a pesquisa bibliográfica e documental, buscou-se demonstrar os espaços de inserção e de divulgação do legado Beltraniano, com a finalidade de sistematizar, inicialmente, essa produção, contribuindo para a formulação de diretrizes capazes de fazer avançar o conhecimento determinados pelos fluxos midiáticos ou por eles intermediados no que tange a produção comunicacional nessa área do conhecimento.

Reflexões sobre o desenvolvimento da prática social e a produção e sistematização do conhecimento matemático

The aim of this study is to reflect about the cultural aspects concerning Mathematics Education, from the relationship betwen the development of the social practice and the production and systematization of knowledge about Mathematics. Thus, in first instance, there is a reflection about the producton level of mathematics knowledge in diverse social contexts, facing the level of complexity of the investigated reality. In a second instance, considerations are made about the necessity of understanding the culture phenomenum, in a totalizing perspective and the implications facing the atomization of culture in researches of ethnographic aspects about the production of mathematics in specific social contexts.

TV digital na Argentina: a TV como palanque eletrônico

The aim of this paper is to describe and analyze the process of implementing the Digital Television in Argentina between November, 2011 and April, 2012, a period where this author has developed postdoctoral research entitled "Digital TV, T-Learning and Edutainment: An Assessment of the Argentine case" at the University of La Matanza in San Justo, City of Buenos Aires, Argentina.

A produção técnico-científica de James Precott Joule: uma leitura a partir da epistemologia de Ludwig Fleck

This paper aims an epistemologically analysis of the attempt of James Prescott Joule to replace the steam engine by the electric one. In this historical analysis, we use the epistemological categories: style of thinking, collective thinking, intercollective circulation of ideas and practices,Joule and other technicians in Machester received in that time financial incentives from governments and industry to replace the steam engine by the electric one, since it was in Manchester a culture of the technique of the accuracy and precision in which Joule was immersed, which allowed us to initially identify the styles of techniques thinking and experimental efficiency. However, Joule could not replace the steam engine by the electric; and the awareness of the problems faced by him, in the attempt to make such a substitution, led him to seek, through an intercollective circulation of ideas and practices, such as the studies of Faraday and Jacobi, a change of direction in his researches. According to our analysis, what happened was a change of style from a technical to a scientific thinking. In this sense, Joule began to investigate issues of a scientific nature, as the Joule’s effect and the mechanical equivalent of heat, which contributed significantly to the establishment of the principle of conservation of energy. We present here the contributions of this epistemological analysis to the discussion of questions of the nature of science in the basic education and for the training of physics teachers.

Influência da música preferida no desempenho e estados afetivos de idosos durante exercício de intensidade auto-selecionada

Low adherence to physical exercise programs is a factor that contributes to the high rates of physical inactivity worldwide. In this sense, strategies to improve the affective responses during exercise are used to impact adherence, as the use of music and self-selected exercise intensity. Despite the benefits of these strategies, there are few studies involving the combination of both (self-selected intensity and music), especially in the elderly population. Thus, the aim of this study was to investigate the influence of music on performance, ratings of perceived exertion (RPE) and on affective and motivational responses of elderly during walking exercise with self-selected intensity. Eleven elderly performed walking sessions on an athletic track in three conditions: without music, with motivational music and with oudeterous music. RPE, mood states, motivation, affective responses, session RPE and attitudes related to the experience of exercise were evaluated. Results demonstrated that both motivational and oudeterous music improved affective responses and decreased RPE. However, only the motivational music condition showed an effect on distance walked, the only presenting a consistent increase in distance. Therefore, it is concluded that the use of music, particularly motivational music, besides increasing the distance walked, reduces RPE and increase pleasure of the elderly during the exercise. Such strategy, in addition to potentially impact adherence positively, can lead to greater benefits and physical adaptations related to the training in the long term

Produção do monóxido de titânio em estrelas variáveis

Mira are pulsating variable stars in advanced stages of evolution. Their atmospheres are sources of intense absorption bands attributed to molecular titanium monoxide (TiO). It has been suggested that the abundance of TiO reaches its maximum value near the minimum light. In this sense, the study of the processes of formation and destruction of TiO in circumstellar envelopes of Mira stars, not only allows us to understand the physical and chemical processes that occur in these environments, as it allows to verify the correlation between the abundance of TiO and its light curve. However, the main mechanisms of formation and destruction of TiO are poorly known and, consequently, the possible correlation between the abundance of this species and the light curve. In these sense, we studied the main processes of formation and destruction of titanium monoxide in molecular layers of Mira atmospheres and determined its temporal variation as function of the stellar radius. The TiO profile along the radius was expected for the different stellar phase, however its abundance is not enough to explain the light curve. The reasons behind it are discussed in details

Análise econômica da eficiência da produção de cana-de-açúcar de fornecedores do Estado do Paraná

The sugarcane industry has been important in the Brazilian economy since the colonial period. The search for alternative energy sources has gained more prominence, by offering a product generating clean energy. With the opening of the Brazilian economy, the sector has undergone transformations operating in a free market environment requiring greater efficiency and competitiveness of those involved in order to stay in business. This scenario is producer/supplier independent, and social aspects related to their stay in the market. Although its share in sugarcane production is smaller than the plant itself, it is still considerable having reached around 20% to 25% in 2008 by employing labor, also production factors had an important economic impact in the regions where they operate. Therefore, this study aimed to estimate the economic efficiency and production of independent sugarcane producers in the state of Paraná through the DEA model. The Data envelopment analysis (DEA) is a nonparametric technique that, using linear programming constructs production borders from production units that employ similar technological processes to transform inputs into outputs.The results showed that of the total surveyed, 13.56% had maximum efficiency (an efficiency score equal to 1). The average efficiency under variable returns to scale (BCC-DEA) was 0.71024. One can thus conclude that for the majority of the samples collected, it might be better use of available resources to the in order to obtain the economic efficiency of the production process.
