This paper aims to make a theoretical reflection on the theoretical compatibility between the program State Employer of Last Resort (ELR) and the Democratic experimentalism (ED). The ED arises in political thought as an alternative to neo-liberal and social democratic programs in order to rescue the discussion about the institutional organization of society and the market economy. About the involuntary unemployment, it proposes tax changes incidents on payroll and proposes work fronts to the most vulnerable or poorly trained. The hypothesis of this paper is that this approach is compatible with the ELR program, the post- Keynesian line. The ELR is presented as transgression of the mainstream of economic thought by proposing that the State acts as guarantor of employment, working as a stabilizing anchor for the economy. On the edge, the ELR proposes eliminate completely involuntary unemployment. The implementation of the ELR, however, requires the construction of institutions that aim to remake the market economy, as well as deepen and energize politics and democracy, goals that are part of the ED program. Thus, the ED would, in theory, an environment conducive to innovative policies guarantors of training and occupation of the individual, essential for their emancipation institutional environment. In Brazil, which has serious infrastructure problems and qualification of manpower, such a program has enormous potential benefit. However when transposed to the Northeast of Brazil through the Plan for the region based on the principles of the ED and the hypothetical coupling to the ELR could not confirm or reject the hypothesis sub-compatibility of these two theoretical frameworks. The findings point to a partial convergence between these two programs

The search for a sustainable development is result of the exhaustion of the natural resources of the planet that demands globalizated politics with practical of compatible economic development with the protection of the quality of life for the future generations. This work presents a study on the thematic on the environmental liabilities in the organizations with focus in the industry of the oil and the production of oil in land in the state of Rio Grande do Norte. Some types of environmental liabilities are presented, as well as, some estimates techniques. Moreover, this work presents surveys of some variable that stimulate the organizations to implant technologies of reduction of the impacts in the environment as: the environmental legislation, costs, the main impacts of the production of oil in land. On the basis of the bibliographical research and in the identified variable, it was carried a case study with state and municipal technician that act in the sectors of fiscalization (IBAMA-RN and IDEMA-RN) with the objective to deepen the discussion regarding the impacts of the industry of the oil, the effectiveness of the current law, the performance of the institutions the federal level and how to prevent impacts in the environment. It was observed that the environmental liabilities are a little spread subject in the organizations, perhaps to be unknown and of few theoretical referencees at the national level, regarding to the evaluation techniques. At the same time, absentee in the national politics that conducts the oil exploration

This work presents a theoretical and numerical analysis of structures using frequency selective surfaces applied on patch antennas. The FDTD method is used to determine the time domain reflected fields. Applications of frequency selective surfaces and patch antennas cover a wide area of telecommunications, especially mobile communications, filters and WB antennas. scattering parameters are obteained from Fourier Transformer of transmited and reflected fields in time domain. The PML are used as absorbing boundary condition, allowing the determination of the fields with a small interference of reflections from discretized limit space. Rectangular patches are considered on dielectric layer and fed by microstrip line. Frequency selective surfaces with periodic and quasi-periodic structures are analyzed on both sides of antenna. A literature review of the use of frequency selective surfaces in patch antennas are also performed. Numerical results are also compared with measured results for return loss of analyzed structures. It is also presented suggestions of continuity to this work

In this work, we study the types of paraphrases used by the students of the Language and Literature Course when they reformulate a source text in the theoretical section of the monographs produced as texts for the conclusion of the course. Our main goal is to know how the process of textual reformulation takes place in the production of the monographic gender. From the used theoretical orientation (Fuchs,1982; 1994; Charaudeau and Maingueneau, 2006; Fávero et al, 2007; Hilgert, 1997, 2002, 2006; among others) we have worked with the paraphrase notion as an activity of discoursive reformulation, considering as the basic groundings the situation of communication and the subjects, or the wider context. In a more specific way, we have considered that the paraphrase performs alterations in the formal level, in the semantic level and in the functional level. Besides that, we sought to articulate the practice of paraphrasing to the gender of discourse in which it appears and to the contextual implications involved in the producing of the gender in question, and in doing so we were grounded in Baktin´s (2003) and Maingueneau´s (1998; 2001) postulates. For the analysis of the corpus that consists of 19 monographs, we have used the three categories defined by Hilgert (2002, 2006):expansion, condensation and parallelism as a way of identifying, describing and characterizing the types of paraphrases used by the students who produced the monographs when they take up Travaglia´s (1996) text about the language conceptions. The results show that the use of the paraphrastic parallelism (with 69.45 % in relation to only 18.41% of condensation and 12.13 % of expansion) was the most recurrent in the reformulations performed by the students who produced the monographs and this manifestation was characterized mainly by the lexical-semantic repetition of fragments of the source text. We have concluded that the high incidence of paraphrastic parallelism is an indication that the student does not have a command of the ways of production and circulation of the discoursive genders uttered in the academic-scientific realm

In the past 50 years, large efforts have been made toward the understanding of the stellar evolution. In the observational context, large sets of precise measurements of projected rotational velocity were produced, in particular by the Natal and Geneva groups. From these data, it is now possible to establish the behavior of stellar rotation from the turnoff to the red giant branch. In addition, these data have shown the role of tidal effects on stellar rotation in close binary systems. Nevertheless, relatively little attention has been paid to theoretical studies on the evolution of rotation along the HR Diagram, a topic itself directly associated to the evolution of the stars. Basically, there are two reasons for such a fact, (i) spherical symmetry is not assumed, what leads to a substantial increase in the numerical complexity of equations and (ii) non rotating models have been very successful in explaining relevant observational data, including the mass-luminosity relation and chemical abundances. In spite of these facts, it is clear that considerable work remains to be done on the role of rotation in the later stages of the evolution, where clear disagreements arise from confrontations between theoretical predictions and observations. In the present work we study the evolutionary behavior of stellar rotation along the HR Diagram, taking into account constraint conditions issued from recent observational survey of rotational velocity carried out with high precision procedures and new evolutionary codes

The projected rotational velocity together with lithium abundance and the onset of the dilution by the deepening in mass of the convective envelope provide a key tool to investigate the so far poorly understood processes at work in stellar interiors of solar-analog stars. To investigate the link between abundances, convection and rotational velocities in solar-analog G dwarf stars, we study a bona fide sample of 118 selected solar-analog G dwarf stars presenting measured lithium abundances, rotational velocities, and fundamental parameters together with computed evolutionary tracks (Toulouse-Geneva code) for a range of stellar masses around 1 M and metallicity consistent with the solar-analog range. The aim of this work is to build up an evolution of lithium and rotation as a function of stellar age, mass, effective temperature, and convection. We analyze the evolutionary status of the sample of 118 solar-analog G dwarf in the HR diagram based on Hipparcos data and using a grid of stellar models in the effective temperature and mass range of the solar-analog stars. We discuss the deepening (in mass) of the convective envelope and the influence on the Li abundances and projected rotational velocities. We determined the stellar mass and the mass of the convective envelope for a bona fide sample of 118 selected solar-analog G dwarf and checked the evolutionary link between the rotational velocity, lithium abundance, and the deepening of the convective envelope. Fast rotators (vsini 6 km s��1) are also stars with high Li content. Slow rotators present a wide range of values of log n(Li). Our results shed new light on the lithium and rotational behavior in G dwarf stars. We confirmed the presence of a large Li abundance spread among the solar-analog stars and concluded that the solar twins probably share a similar mixing history with the Sun

Research on Legal Deontology dedicated to theoretical and applied ethics on judicial conduct grounded in legal principles and rules set out in the Constitution of the Federative Republic of Brazil and the Organic Law of the National Judiciary, also contemplating propositional instruments covered by the constitutional system, which conveys behavioural paradigms inserted in the Bangalore Principles of Judicial Conduct, in the Universal Statute of the Judge and in the Latin-American Code of Judicial Ethics, as well as highlight the influence of those instruments in the Brazilian Ethical Code of the Magistrates and in the official complementary training of judges in charge of Judiciary Schools. The study provides the theoretical influxes of moral norm, passing by behavioural social norm to consolidate the ideal standards of judicial conduct into legal standards and related instruments. The Legal Deontology directed to the ethical judicial conduct is confronted with the stereotype that society expressed in relation to the judge's person, who is the political agent that interprets the law for making decisions which directly influences the realization of access to justice, that is constitutionally guaranteed to all. Core values inserted in the constitutional system intended to discipline the judicial conduct are presented and analysed under a critical view, since they are enclosed in prescriptive language that conveys behavioural aspects open to interpretation and which compliance is revealed as a proposition focused on promoting a better solution of interest’s conflicts under the responsibility of those who constitute the distinctive corporation of the Judiciary. The theme’s contextualization also focuses on applied ethics, based on the approach of normative and propositional instruments of deontological content, still focusing on the study of real cases examined by the Brazilian National Council of Justice, as part of its correctional goals.
