Propomos discutir como Os sertões foi incorporado, pela crítica, como obra de literatura e como, posteriormente, o romance Grande sertão: veredas passou a ser lido como ensaio. Para tanto, examina-se, de um lado, em vários estudos, como o primeiro foi consagrado como obra compósita, pertencendo, ao mesmo tempo, ao campo da literatura, da sociologia e da ciência, o que se tornou moeda corrente e cânone quase inquestionável, sobrevivendo por mais de um século. De outro lado, investiga-se como a narrativa rosiana passou a ser vista, por uma determinada vertente da crítica, como ensaio ou estudo das relações de poder no Brasil. É essa indistinção, paradoxal, entre sociologia e literatura, ciência e ficção que nos propomos investigar e problematizar, buscando compreender tal embaralhamento de gêneros.

This article points out some elements required for comprehending the work mensagem for marimba solo (2011) by Herivelto Brandino in regard to its compositional process and performance. The text shows how various materials have been chosen for the confection of the work - mainly those related to the act of writing texts - and approaches the composer's queries about the non-necessity, and even the uselessness of composition, performance and artistic objects themselves. At the end we conclude that regardless such a supposed non-necessity of any musical object it is possible to construct a coherent piece based on similar paradoxes that, at first, served to make any compositional work useless.

This paper aims to present a study of the social relationships around the production, circulation and the eventual possibility of appropriation of knowledge in social systems of the pre-modern world and in a social organization of Western capitalist modernity. In this specific universe of relationships, it was also important to noticed that there is a paradoxical role of rationality that served to the emancipation of instruments of control’s knowledge of pre-modern period as in the same time it was favored by the construction of new bonds that were made in the Western modernity through the modern legal system, inserting the knowledge in the domain of the economy and private logic of the capitalist’s system through intellectual property. This research was made from a review of the literature, using specialized books of the theme. It was concluded that there is a paradox in the social relationships about the knowledge, whose cause is related to the unfolding of rationality in the development of Western civilization.

The profession of public relations presents itself in Brazil currently as a profession in expansion. However, by it’s time of performance, it should already be instated and legitimatized by society like other areas that even though appeared later, are already known and understood. Therefore, this project intends to seek for answers about the current situation, analyzing since it’s appearance in Brazil until now a days. With this analysis of the whole historic trajectory it is possible to understand the many movements that occur today in the area of public relations that are constantly searching for a legitimating and valued profession. However in this context surfaces a paradox: How to value something that is not known? So this project starts up again a campaign of divulgation of public relations promoted by the ABRP (Brazilian Association of Public Relations), now on the internet using the social networks, seeking to have a wider audience, interaction and reach. By this campaign it is possible to show to different publics the existence and relevance of the profession in the Brazilian context in objective and practice way making it more comprehensible in Brazil

This work is aimed at examining the paradox of modernity, from the opposition between Enlightenment ideals and historical events that followed, especially during the twentieth century, as well as to study the impact of mismatch on Bioethics, adopting as a reference epistemological critical theory of the Frankfurt School. Bioethics presents itself as a shaky science, devoid of references, and primarily impacted by the emptying of ethics. The reason desubjectivation established by and exacerbated by modern enlightenment, was able to erect dark scary for humanity and promote barbaric practices in the name of a science that promises order and progress. This paradox and the fallacy of reason enlightened by scientific advances are wide open, always accompanied by ethical and moral returns scary. Some examples are the surveys conducted in Tuskegee and Guatemala, and treated in this study, which show how far modern rationality and all its consequences

This article is based on the sociological and historical approach of the origin of the university entrance exams in Brazil and shows the preparatory courses (preps) expanding simultaneously as a strategy of the lower and middle classes to get their children into university. Thus, the paradox of an antipedagogical practice becomes an essential condition for students to have access to prestigious university courses, what justifi es the historical movement by the lower and middle classes to appropriate this practice.. We propose that measures are taken to improve the results of important affi rmative actions that aim to enable students to enter university, as well as highlight Professional Guidance as a necessary resource which constitutes a new challenge in this fi eld of action.

Literature has always had a tense relationship with school. On the one hand, its educational function which is a feature of its own has motivated its insertion into curricula; on the other hand, its pedagogical use seems to defile its esthetical value. Such a paradox may be clearly observed in juvenile literature whose specificity has not always been acknowledged. To discuss the alleged specificity of that literary subgenre and its use in school, this essay compares the books A órbita dos caracóis (2003), by Reinaldo Moraes, and Se eu fechar os olhos agora (2009), by Edney Silverstre, which have in common their possible destination to the juvenile public, even though neither of them has been conceived of with that purpose in mind.

The use of fractional calculus when modeling phenomena allows new queries concerning the deepest parts of the physical laws involved in. Here we will be dealing with an apparent paradox in which the time of transference from zero in a system with fractional derivatives can be strictly shortened relatively to the minimal time transference done in an equivalent system in the frame of the entire derivatives.

The intrinsically relativistic problem of spinless particles subject to a general mixing of vector and scalar kink- like potentials (similar to tanh gamma x) is investigated. The problem is mapped into the exactly solvable Sturm - Liouville problem with the Rosen - Morse potential and exact bounded solutions for particles and antiparticles are found. The behavior of the spectrum is discussed in some detail. An apparent paradox concerning the uncertainty principle is solved by recurring to the concept of effective Compton wavelength.
