A taxa de câmbio do Brasil é válida no longo prazo?

The objective of this study was to test the validity of the real exchange rate in the long run. For that five tests were performed based on equation, which relates to real exchange rate, international trade, domestic income. The main difference is that the tests when we are working with quarterly data, the parameters are significantly different from zero – i.e., the variables real exchange rate, international trade, domestic income and net exports on long term relationship – and, moreover, the signs are as expected. This implies that it is possible to increase exports with currency devaluation. Thus, based on data and tests that work we conclude that the exchange rate is an important instrument of trade policy, given that devaluations are valid even in the long term.

Restrição externa e taxa de câmbio no Brasil: 1980-2008

The objective of this study is to examine if economic growth in Brazil was blocking due to external constraints, that is, in consequence of its Balance of Payments. We work with the approach first proposed by Thirlwall (1979) which was later modified by Lima and Carvalho (2009). We can conclude that economic growth was restricted by the external sector, which is consistent with the economic history of Brazil, and verify that the real exchange rate, and to influence the trade balance in the course run, also excerce some influence on this account balance of payments in the long run.

A concepção de cultura em Vigotski: contribuições para a educação escolar

Este trabalho analisa a concepção de cultura em Vigotski, procurando responder qual a ideia de cultura presente na obra desse autor para, a partir dela, destacar a importância do ensino escolar no desenvolvimento dos indivíduos. A influência da cultura sobre o desenvolvimento psicológico era estudada por esse autor a partir da análise do processo de emprego de signos como meios auxiliares das funções psíquicas, transformando-as de funções espontâneas em funções voluntárias. As funções psíquicas mediadas pelo uso dos signos existentes na cultura eram consideradas como funções superiores por Vigotski, sendo assim, imprescindíveis para o desenvolvimento do homem. A cultura para este autor é produto das leis históricas determinadas pelas condições concretas da existência humana e, assim sendo, o homem nessa perspectiva produz cultura, mas também é fruto das relações sociais, que são internalizadas por ele e que se expressam na forma de funções psíquicas.

A concepção de criança e alei de nove anos

The historical analysis of the conception of child is essential to understand the speeches, public policies and actions that are set aside for them. The 20th century ´ social-economic changes and the consequent need for women's work produced a restructuring not only in the family, but also in the care and attention focused on childhood. The present article under the perspective of Cultural-historical approach aims to make a reflection about the conception of child in the educational context, especially in the face of recent public policies that favor education´s advance in state schools. Besides, they also intend to point out some consequences and possible problems that may arise with their implementation and discuss the implications for the teacher´s organization of methodological practice and the relationship between development and learning.

A importância de Scotus na concepção de história de Arendt

The objective of this study is to discuss the notion of history in Arendt, from the importance that needs the thought of Duns Scotus, particularly with regard to the primacy of the will. For the author, Scotus was a medieval thinkers to emphasize the role of free will as power in the face of intellect attached to the natural activity. The freedom to get an act featuring a world ruled by contingency. Now, for Arendt, that freedom is consistent with your idea of authentic political, and base a public space, defined by word and action of individuals. The history, which takes place from political activity, received various treatments, from Greek antiquity to the modern conception of process. It joined the idealistic conceptions, establishing universal ways of defining the future. However, if freedom is to characterize the vita activa, the history must seek the meaning of the facts to scrutinize their singular aspects, which fell to the continuo of universal explanation of the official history. It is, therefore, to approach the history from the perspective of singular narrative, from the spectators, those who founded the public space. Hence the importance of bipolar concepts such as nature and freedom, necessity and contingency, will and intellect, as Scotus.

A caricatura política na concepção libertária do periódico A Plebe (1947-1949)

This article discusses the meanings of imagistic representations (drawings, cartoons) published in A Plebe (The Plebs), from May 1947 to May 1949, the last period of the Edgard Leuenroth’s headship. Created in 1917, the newspaper, supported by libertarian principles, set up as a public sphere suited for the proletarian world because of discussing the problems that workers were facing in their daily lives. The paper printed whipping criticisms against the country's elites and fought, without respite, the capitalist system – qualified as parasitic, violent and expropriator –, supported by mystifying and equally violent enactments from its religious arm, expressed in the actions of the Catholic Church and whose struggle against was also systematic.

Avaliação da construção e operação de técnicas compensatórias de drenagem urbana: o transporte de finos, a capacidade de infiltração, a taxa de infiltração real do solo e a permeabilidade da manta geotêxtil

This work aimed to evaluate some aspects of construction and operation of full-scale best management practices and their effects on infiltration loading rate. Two systems were studied: i) filter-swale-trench (FST) and ii) infiltration well (IW). In these units, field essays and full-scale measurements were made in order to assess the soil permeability. Further, the fine particles transportation and the geotextile blanket permeability were determined before and after operation. The results pointed out that there were soil transportation to inside the FST and IW systems, despite of the installed protections, and that these material were responsible for diminishing the geotextile (reduction from 30 to 90% for FST and 40 to 70% for IW) and the full-scale infiltration loading rates (varying from 4,7 x 10-6 to 10-5 m.s-1).
