Recentemente as expectativas de inflação de mais longo prazo passaram a ficar desancoradas da meta. A fim de testar a perda de credibilidade no compromisso do Banco Central do Brasil de trazer a inflação para o centro da meta, inicialmente, recriamos indicadores de credibilidade para essa instituição e encontramos que esses índices estão em patamares relativamente baixos em termos históricos. Em seguida, calculamos a função de reação do Banco Central utilizando uma Regra de Taylor em janelas moveis de cinco anos no período 2005-2014 como uma tentativa de justificar essa queda da credibilidade nos últimos anos. Os resultados apontaram uma mudança mais acentuada na função de reação do Banco Central do Brasil a partir de 2013, em que a variável hiato do produto ganhou maior importância e o desvio da inflação em relação à meta perdeu significância. Essa mudança pode ter sido um dos principais geradores para a queda recente de credibilidade.

O objetivo desta pesquisa é mostrar que há uma relação positiva entre a estabilidade política-institucional, a credibilidade e a taxa de poupança privada. Parte da literatura recente sobre disparidades entre taxas de poupança usa um argumento de economia política para explicar como a instabilidade política-institucional pode afetar as decisões públicas que determinam a poupança pública, mas não sugere da mesma forma que tal instabilidade pode atingir negativamente a poupança privada. Analisar-se-á esta lacuna da teoria partindo-se do referencial teórico da Nova Economia Institucional (NEI), onde salienta-se, nos processos de decisão privada de acumulação de ativos, o papel do governo gartantindo (i) a estabilidade das regras de mercado e (ii) os direitos de propriedade. A pesquisa envolverá uma análise teórica microeconômica da determinação da poupança privada usando a visão da NEI. O interesse prático fundamental da pesquisa é tentar justificar, em parte, os baixos níveis de poupança na América Latina usando um argumento institucionalista e, desta forma, propor ações de governo e reformas.

The Social Representation Theory provides subsidies to scientifically analyze what is called common sense, suggesting that thought be given credibility to the individual, from the assignment of logic to it. The Representations allow us to interpret, understand, explain and thus classify information, events and people. In this sense, this study aimed to analyze how social representations of the actors of the intinerant traders who operate in Ponta Negra/RN can be used as an element for tourism planning. To achieve the desired goals, we conducted a qualitative study, from a descriptive study, using methods of data collection the research literature, the technique of free association of words and the questionnaire, applied with 90 intinerant traders who work in Ponta Negra/RN beach. As tools of data analysis were used to analyze literature, and software EVOC and SPHINX. This research has revealed the predominance of people in itinerant male, between 18 and 28 years, with incomplete primary education, no contributors of Previdência Social and working seven days a week. The core elements of representations brings that explain that their knowledge is guided by collectively shared knowledge in the culture of tourism, which is seen as something that brings economics benefits (money) to the society, from the travel and entertainment. The plan represents the forward thinking, based on development plans that seek improvements and organization. The structure and operation of tourism planning in Natal/RN, there were no representation of intinerant traders. It is concluded that understanding the needs of itinerant traders provides grants to developing strategies for the development of tourism. This is achieved from its inclusion in tourism planning, since it enables tourism managers to understand how they are capturing, interpreting and acting on their next reality, since these representations are fundamental in forming opinions and the establishment of individual attitudes and collective. Thus, it is an important theory to be used to subsidize social research with individuals living reality and local needs, but which is the margin of decision-making processes of economic in the Brazil

The application of sand filters in localized irrigation systems is recommended in the presence of organic and algae contamination. The proper design and maintenance of these equipments are essential to assure an effective water quality control, in order to reduce the emitters clogging, to keep its water application uniformity, and to prevent increasing in the system operation costs. Despite the existence of some references about design, operation and maintenance of these filters, they are dispersed, with not enough details to guarantee the optimization of its hydraulics structure design and the proper selection of porous media to be used. Therefore, the objective of this work was to report a current literature review, relating practical information with scientific knowledge. The content of this review would help to induce and intensify the research on this subject and to contribute so the operational functions for the equipment are reached. It is also expected to assist the improvement of the filtration and flushing processes in the agricultural irrigation and the development of original design procedures and the rational use of these devices.

This paper tries to show that the developments in linguistic sciences are better viewed as stages in a single research program, rather than different ideological -isms. The first part contains an overview of the structuralistas' beliefs about the universality and equivalence of human languages, and their search for syntactic universals. In the second part, we will see that the generative program, in its turn, tries to answer why language is a universal faculty in the human species and addresses questions about its form, its development and its use. In the second part, we will see that the paper gives a brief glimpse of the tentative answers the program has been giving to each of these issues.

The main purpose of this paper is to question the relationship between theory and practice or basic and applied research in the domain of Applied Linguistics and classroom discourse. In order to achieve our aim, some theoretical texts, some recorded and transcribed classes as well as some teachers and students opinions about reading and writing were analysed. Results have shown that 1) practice is not the direct application of theoretical data: the relationship between them is not as simple as some applied linguists seem to believe because of the action of the unconscious in the constitution of subjectivity; 2) the conceptualization of the theoretical issues takes place in a confused and disorderly manner mixed up with personal experiences and previous knowledge (practice). We intend to question the fact that practice comes as secondary to theory.

In this paper I present some evidencie that forces us to conclude that within the Minimalist Program (Chomsky 1993; 1995), Binding Theory (BT) should be computed after LF (Logical Form). I show that derivations leading to structures containing violations of BT-Principles must converge at LF, since less economical alternative derivations respecting those principles are also ungrammatical. Being irrelevant to the notion of convergence, BT must apply after LF. A similar reasoning reveals that the Theta-Criterion should have the status of a bare output condition appling at LF, since less economical derivations are allowed by the computational system to prevent violations of it.
