Aspects of Transformer Fires in Brazil  [PDF]
Dayse Duarte
Open Journal of Safety Science and Technology (OJSST) , 2012, DOI: 10.4236/ojsst.2012.23009
Abstract: For the last 20 years blackouts have been included in the list of major disasters that includes storms, hurricanes, earthquakes and floods. Therefore consumers have become increasingly aware of fires and explosions involving oil-filled transformers located in power plants or substations. Owing to several fires in transformers, the summer of 1997 became known to the people of Rio de Janeiro, Brazil, as the The Summer of Blackouts. The losses incurred by a blackout are not merely financial. In fact, the loss of operational utility by fire represents only a minor part of the total overall cost in terms of energy availability, human loss and organizational reputation. The costs resulting from the lack of fire risk management in the electrical power industry are no longer acceptable to Brazilian society. The objective of this paper is to address important aspects of transformer fire risk in the context of the Brazil. The aim is to help engineers recognize the implications of decisions concerning the operation of transformers over their life cycles.
Imaginando a los mayas de hoy: autorrepresentación y política
Duarte Duarte, Ana Rosa;
Estudios de cultura maya , 2008,
Abstract: in this article i analyze the processes of representation and self-representation of the yucatec maya in sáastal: the children of the sacred grace, a 55-minute video-fiction. sáastal presents a dramatic account of the everyday life of a yucatec maya family as imagined both by the maya and non-maya participating in the production. i examine how this imaginary is influenced by the coexistence of the mayan culture with the diverse civilizatory politics, such as the politics of development, modernization, and globalization. it is argued that this coexistence has led us, the yucatec maya, to adopt "soft identities" which allow us to act according to the circumstances. in sáastal we therefore perform, recreate and instrumentalize our culture and, in this way, convert our own identities into fictions.
Imaginando a los mayas de hoy: autorrepresentación y política
Ana Rosa Duarte Duarte
Estudios de cultura maya , 2008,
Abstract: En este artículo se analiza el proceso de representación y autorrepresentación de los mayas de Yucatán en Sáastal: Los hijos de la Santa Gracia, una video-ficción de cincuenta y cinco minutos. En Sáastal se pone en escena el drama de la vida cotidiana de una familia maya de acuerdo con la imaginación, tanto de los mayas que participamos en la producción como de los no mayas. Se analiza cómo la convivencia de la cultura maya con las diversas políticas civilizatorias, entre éstas, las de desarrollo, modernización y globalización, han influido en el imaginario de los mayas contemporáneos. Esta convivencia entre dos culturas ha llevado a los mayas a adoptar "identidades suaves", que les permiten actuar de acuerdo con las circunstancias. En Sáastal, los mayas "performamos", recreamos e instrumentalizamos la cultura y convertimos en ficticias nuestras propias identidades.

Conhecimento tácito e conhecimento escolar na forma??o do professor (por que Donald Sch?n n?o entendeu Luria)
Duarte, Newton;
Educa??o & Sociedade , 2003, DOI: 10.1590/S0101-73302003000200015
Abstract: this paper defends that donald sch?n's works on professional education in general and more particularly on teachers' education are based both on an epistemology that devalues scientific knowledge and on a pedagogy that devalues school knowledge. a critical analysis of sch?n's concepts of tacit knowledge (or reflection-in-action) and school knowledge is presented. this critical analysis is inserted in the context of a criticism of the currently hegemonic epistemological ideas in the field of studies on teachers' education.
A anatomia do homem é a chave da anatomia do macaco: a dialética em Vigotski e em Marx e a quest?o do saber objetivo na educa??o escolar
Duarte, Newton;
Educa??o & Sociedade , 2000, DOI: 10.1590/S0101-73302000000200004
Abstract: vygotsky, in his manuscript concrete human psychology, asserts that the relationship ontogeny-philogeny in cultural development is different from the same relationship in organic development: the human fetus develops itself without an interection with a mature biotype, whereas in cultural development this interaction is the most important force for all development. thus, this article analysis the relationship between the dialectics present in vygotsky and in marx, substantiated in methodological and epistemological reflexion done by marx on the text whereby he asserts that "the human anatomy is the key for monkey anatomy". the conclusion of this article defends that vygotsky's psychology supports a pedagogy which one appreciates the conduction of children to learn the highest objective knowledge produce by all mankind.

Esquematismo e semiforma??o
Duarte, Rodrigo;
Educa??o & Sociedade , 2003, DOI: 10.1590/S0101-73302003000200007
Abstract: this paper aims at showing the relationship between "theory of semi-erudition" by adorno and his (and horkheimer's) suggestion found in the dialectic of enlightenment, that the culture industry removes the individual capacity to "schematize", that is - according to kant's point of view in the critique of pure reason - to refer their sensible perception to fundamental concepts. since in the dialectic of enlightenment, in the chapter on the culture industry, the authors do not develop this idea, i try to find a development of it in the part entitled "elements of anti-semitism", particularly in the section on the "false projection". it is then possible to show that the same conception of "semi-erudition", which, in the dialectic of enlightenment, links the theory on anti-semitism to the critique to the culture industry, may be considered as a concept applied to educational issues.
A contradi??o entre universalidade da cultura humana e o esvaziamento das rela??es sociais: por uma educa??o que supere a falsa escolha entre etnocentrismo ou relativismo cultural
Duarte, Newton;
Educa??o e Pesquisa , 2006, DOI: 10.1590/S1517-97022006000300012
Abstract: the thesis of the end of the meta-narratives defended by postmodernism implies the negation of the universality of culture. it is not just the fact that human culture has not yet achieved true universality, and not even the fact that the ruling classes have so far subjected human culture to their own private interests and, to that end, have suffocated and destroyed much of the wealth contained in local cultures. to postmodernism the problem does not reside in the bourgeois vision of human culture, but in the very idea that a universal culture can exist. postmodernists declare that any educational project based on the idea of the existence or possibility of a universal culture is a conservative, authoritarian, ethnocentric project. this text argues for the thesis that the marxian conception of the historic process of constitution of the universal human wealth incorporates the theoretical elements necessary to overcome the false option, postulated by the various postmodernist trends, between ethnocentrism and cultural relativism. in marx, the universalization of human culture in the capitalist society takes place through the universalization of the exchange value of the goods as the fundamental mediation of social relations. it is, therefore, a dialectical process in which the humanization and the alienation of the human genre and of the individuals occur at the same time. the text concludes with the presentation of the challenges that, based on this marxian conception of universal wealth, must be faced in the process of constructing a marxist pedagogy.

Duarte,Alice;
Etnográfica , 2010,
Abstract: the paper begins by placing in time the emergency of consumption as an area of anthropological investigation, seeking to expose the circumstances that made the establishment of an anthropology of consumption rather difficult. next, following the development steps within that area of studies, the paper presents a selective synthesis of authors and works that, in any way, are making a change to a real concern on the study of consumption.
