Potencial de redução na demanda por energia elétrica no Rio de Janeiro através do modelo de preço variável

A energia elétrica é fundamental para o desenvolvimento de qualquer país e o Brasil atravessa atualmente uma crise energética devido ao baixo nível de seus reservatórios, então diversos temas sobre o sistema elétrico brasileiro vêm à tona a fim de dar mais confiabilidade e evitar futuros racionamentos, permitindo assim que a escassez de energia não seja um impeditivo para o crescimento econômico do país. O presente estudo calcula o potencial de redução de demanda por energia elétrica no estado do Rio de Janeiro através do modelo de preço variável, que consiste em ter tarifas distintas para o horário de ponta e fora de ponta. Este é um entre diversos programas de eficiência energética existentes no mundo atualmente. Para tal cálculo as principais premissas são a projeção de demanda máxima coincidente, o número de consumidores por classe e a elasticidade preço da demanda por energia elétrica. A partir dai são sugeridos três cenários de penetração de AMI (Advanced Metering infrastructure), e três cenários de variação de preço, chegando assim a nove resultados possíveis.

Abordagens pedagógicas na formação de enfermeiros : compreensão de docentes de enfermagem

In the new world order is notorious changes in social, ethical, economical and political aspects in the society, which reach incisively higher education, requiring a number of modifications and a new vision in nursing education, in order to meet the demands of the Unique Health System. Thus, the Higher Education Institutes (HEI) and teachers are invited to face new challenges and reflect on their practices, using pedagogical approaches and innovative methodologies to meet the requirements of a globalized society. This study has as an objective to analyze the perspective of teachers in what concern the pedagogical approaches used in nursing education and to identify pedagogical approaches utilized by teachers in nursing education. This is a field research of exploratory kind, descriptive, of quantitative approach. The search was conducted at the Department of Nursing of the Federal University of Rio Grande do Norte UFRN, based in the city of Natal. The population consisted of forty-six teachers. From this population was selected a sample of twenty teachers. Data collection occurred from August to September 2011, through the utilization of the technique of interview and questionnaire. The obtained data were analyzed in two moments. In the first moment, was carried out the quantitative analysis that refers to the obtained data through the interview technique, methodological procedures were submitted to the content analysis proposed by Bardin. On the second moment, concerning the quantitative analysis of the questionnaires applied to the teachers and of the identification data, which were digitized and transferred to a spreadsheet electronic of Microsoft Excel XP, tabulated and organized into tables, containing their relative and absolute frequencies. It is worth mentioning that were respected the aspects of the CNS Resolution 196/96. With regard to the characteristics of research participants, 20% were male; with a degree of titration of 55% doctorates; regarding time of service there was a greater representation from 15 to 45 years, with 45%. The results showed that 90% of teachers who participated in the research have an appropriate understanding of non-critical pedagogical approaches, only 10% had an inadequate understanding. However, 70% of teachers, despite having an adequate understanding, reported difficulties when attempting to implement these pedagogies. Most teachers, with representability of 80% consider the non-critical pedagogies relevant in nursing education, as well as critical pedagogies, being represented by 95% of teachers. It was concluded that both critical and non-critical pedagogies are in teachers practice of undergraduate nursing education. It feels like a moment of transition, since the presence of new ways of teaching as a part of this educational context, with educational models that give value to scientific, ethical and personal aspects in the educational process. The research contains limitations, however highlights the contribution of new possibilities for action, reflection on the context of performance, maximizing the pedagogical skills necessary to conduct teaching process, in line with the new educational paradigm of higher education

Trayectoria tecnológica Web y el orden digital en Latinoamérica: reflexiones históricas desde Brasil

The emergence of the digital order renewed the Victorian civilizing ideal and strengthened a world order of techno-economic dependence. The new grand narrative is the urgency of digital transformation of societies; a dream pursued without reflection by the populations of the periphery that ended into in a collision between McLuhan's two informational orders: cold and hot societies. Latin America as part of the periphery did not participate in the development of the informatic technologies and its historical legacy made the appropriation of these technologies more difficult. This paper examines the historical circumstances of this process: the development of a discourse around the digital networks, the consequences of this social construction in the region, the fragile efforts of Brazil to create technology, and the entrance of IT networks in the region. The results showed that the status of this kind of research in the region is weak so we alert about its consequences. We concluded that to create an informational order that may serve as a space of self-affirmation, freedom and heterogeneity, it is necessary to have a deep knowledge of the social and historical context that created its basic technologies, but Latin America is indifferent in such regard. Information Science has a central role in the region within this process but it has not developed it yet.

Os deslimites da poesia e os reflexos do mundo: uma leitura de No banheiro um espelho trincado

Lyric poetry is where the relationships between world perception, language and representation are mostly problematized. In fact, poetic creation oscillates between the desire of a realistic expression of the world, beings and things and the understanding that its urgent task is simply to reinvent the world order and denaturalize it. Thus, Sérgio Mello’s poems in No Banheiro um Espelho Trincado (2004) conceive a poetry mainly concerned on the tension between words and things; between the lyric subject and the world; between language and the reality it encloses, through groups of images that range from the natural to the rupture process. His poems are small pieces of narrative, scenes that are articulated through the cutting technique, like the process of a cinematographic edition.
