Programa de Avaliação de Desempenho: elementos constitutivos e pressupostos na prática avaliativa

This study analyzes the perceptions of technical and administrative UFPA, in relation to the insertion of the components and assumptions of DBP in evaluation practice. Addresses the history, concepts, meanings, about AD methods, skills, evaluation skills, the APF and AD UFPA and Programme itself. The research is characterized as a hypothetical-deductive, descriptive and applied, using the case study. Data were analyzed using a quantitative approach, using the descriptive and inferential statistics. Data were collected through the application of questionnaires to 222 technical and administrative searched IFES, not occupants of FG and CD. The results indicate that the factors perceived in relation to the constituent elements such as: evaluation practice, measurement of competence, program management, timing, individual skills and fundamentals of the program and those related to assumptions such as: democratic process, integrative perspective, character development and pedagogical continuous evaluation practices are perceived in the evaluation process. The study concludes that comparing the results of the constituent elements and assumptions of the PAD of thechnical-administrative UFPA, it can be said about a tendency to change, though subtle, compared to the traditional model of AD, directed only to the granting of career progression for a new logic based on the results, showing an early effectiveness of the program evaluation practice by law and by the Institution. The results are confirmatory of advance evaluation practice in the institution, more so than has previously been expected, which demonstrates the value of scientific criteria of scientific research

A aplicação do acordo sobre subsídios e medidas compensatórias pelo estado brasileiro

The Multilateral Trading System has evolved and presented new international mandatory rules to States. Along with the World Trade Organization constitutive treaty, Brazil has incorporated the Agreement on Subsidies and Countervailing Measures (ASCM) in the national legal system. That treaty limits de scope of subsidies concession by governments since this practice can constitute a mechanism of commercial disloyalty, affecting national industrial development in the importing country. At the same time, the multilateral agreement grants defense legitimate instruments to States, among them the possibility of domestically and unilaterally imposing countervailing measures to subsidized products that enter the national territory. Since the issue concerns both international and domestic level in complementary grounds, this research, besides investigating the treaty related obligation, aims at studying the national legal fundaments to ASCM s application by the Brazilian State. Therefore, the essential point resides in the State s conduction of its international trading and also in its available and constitutionally established mechanisms of economic intervention. State s regulating power reveals itself as a fundamental prerogative to succeed in the internalization of international agreement s requirements in the domestic legal system, which represents a basic prerequisite to the implementation of countervailing measures. Once the whole normative outlines are apprehended, this study shall scan the administrative process of trading defense main elements, along with the means of controlling public administration acts. The action taken by the public organs that directly intervene in foreign trade shall be analyzed as well, so as to enable reasoning if the unilateral application of countervailing duties by the Brazilian State is happening on legitimacy grounds

Modelagem numérica de estruturas de contenção atirantadas em areia

A numerical study on the behavior of tied-back retaining walls in sand, using the finite element method (FEM) is presented. The analyses were performed using the software Plaxis 2D, and were focused on the development of horizontal displacements, horizontal stresses, shear forces and bending moments in the structure during the construction process. Emphasis was placed on the evaluation of wall embedment, tie-back horizontal spacing, wall thickness, and free anchor length on wall behavior. A representative soil profile of a specific region at the City of Natal, Brazil, was used in the numerical analyses. New facilities built on this region often include retaining structures of the same type studied herein. Soil behavior was modeled using the Mohr-Coulomb constitutive model, whereas the structural elements were modeled using the linear elastic model. Shear strength parameters of the soil layers were obtained from direct shear test results conducted with samples collected at the studied site. Deformation parameters were obtained from empirical correlations from SPT test results carried out on the studied site. The results of the numerical analyses revealed that the effect of wall embedment on the investigated parameters is virtually negligible. Conversely, the tie-back horizontal spacing plays an important role on the investigated parameters. The results also demonstrated that the wall thickness significantly affects the wall horizontal displacements, and the shear forces and bending moments within the retaining structure. However, wall thickness was not found to influence horizontal stresses in the structure

Método de Otimização Topológica em Estruturas Tridimensionais

The topology optimization problem characterize and determine the optimum distribution of material into the domain. In other words, after the definition of the boundary conditions in a pre-established domain, the problem is how to distribute the material to solve the minimization problem. The objective of this work is to propose a competitive formulation for optimum structural topologies determination in 3D problems and able to provide high-resolution layouts. The procedure combines the Galerkin Finite Elements Method with the optimization method, looking for the best material distribution along the fixed domain of project. The layout topology optimization method is based on the material approach, proposed by Bendsoe & Kikuchi (1988), and considers a homogenized constitutive equation that depends only on the relative density of the material. The finite element used for the approach is a four nodes tetrahedron with a selective integration scheme, which interpolate not only the components of the displacement field but also the relative density field. The proposed procedure consists in the solution of a sequence of layout optimization problems applied to compliance minimization problems and mass minimization problems under local stress constraint. The microstructure used in this procedure was the SIMP (Solid Isotropic Material with Penalty). The approach reduces considerably the computational cost, showing to be efficient and robust. The results provided a well defined structural layout, with a sharpness distribution of the material and a boundary condition definition. The layout quality was proporcional to the medium size of the element and a considerable reduction of the project variables was observed due to the tetrahedrycal element

Nietzsche e Rosset: alegria, impulso à criação

Understood in a project of transvaluation of values, the joy is one of the central themes of the thought of Friedrich Nietzsche and Clément Rosset. Opposed to the dogmatic philosophy that moralize and robs your strength to think of it as "happiness", evaluated, in short, a target linked to virtue and rationality these thinkers propose a perspective that makes the joy of point to an instance extraterrestrial and back to the earth, to the body. In this vein, beyond the oppositions of values constitutive of metaphysics dogmatic, the joy and suffering are conceived as elements that are not mutually exclusive, they are complementary as foundations of a gaia(ta) science, based in laughter and friendship. Contents of a tragic wisdom that leads to an unconditional fidelity to the real (expressed in formulas of amor fati Nietzsche and unrestricted approval of existence Rosset), the joy is then interview as vital impulse, the force majeure, the strength plastic encourages artistic creation: the joy of children playing

Exploração sexual comercial de crianças e adolescentes : o estado da arte nas produções acadêmicas em psicologia

The Commercial Sexual Exploitation of Children and Adolescents (ESCCA) is a phenomenon that has been given priority in public policy agenda of many democratic governments of Western countries and civil sectors of society, besides the object of studies in different fields of knowledge. Psychology is among these areas and is considered one of the references in the construction of knowledge and actions to confront the phenomenon. However, the epistemological foundations of psychological science are quite different, and so, several are his speeches, knowledge produced and ways of conceiving man and the world. This is evident in the publications of psychology on ESCCA. This work aims to achieve a state of the art of psychology publication in Brazil (in the post-graduation - through theses and dissertations - and journals) on the Commercial Sexual Exploitation of Children and Adolescents. More specifically try to evidence (a) what conceptions of commercial sexual exploitation of children and adolescents the authors lists, (b) what are aimed at research and publications, (c) how the research and issues are justified, and (d) that theoretical approaches the authors are affiliated and methodological possibilities are applied to range the aim proposed in their work. In order to do so, a survey was conducted in the major index sites (eg, BVS-Psi, Capes, theses and dissertations database of university libraries) of the material, covering the period 1990 to 2007. Through research on these sites, we built a database, including information relating to the work sought from specific descriptors for studies in the area of victimization of children and adolescents, with reference to a list provided by Faleiros (2000). After reading the summary of the work, the number of recovered 25 productions was reached - including theses, dissertations and articles. For analysis of the material used in the analysis of thematic content. Two axes themes were established in order to guide the analysis: conceptual elements of commercial sexual exploitation, and theoretical and methodological strategies employed. The axes have as reference for analysis a chapter built on the concept of commercial sexual exploitation, so that all analysis is anchored on it. The analysis points to the existence, still strong, conceptual and terminological confusion about ESCCA. Few studies have not demonstrated this confusion, maintaining a consistent theoretical approach. In relation to the theoretical and methodological strategies, there is a great diversity of approaches in psychology surrounding the phenomenon of ESCCA, enriching levels of understanding and action. This diversity reflects a constitutive heterogeneity of psychological science. We emphasize the perspective of socio-historical psychology, most frequently among the publications. It is hoped that this research will help advance the qualitative approach to ESCCA, especially in the field of psychology, as well as contribute to new research in the area and construction of new means of addressing this human rights violation

Fragilidade ambiental da bacia hidrográfica do Rio Seridó (RN/PB Brasil)

There are many applications coming from geomorphological studies and their different constitutive and inter related elements, to the implementation of public politics of planning and environmental management. This search presents an analysis of the environmental fragility of the watershed of Seridó River, situated between the states of Paraíba and Rio Grande do Norte (Brazil), including the identification of possible unstable areas. It is based on the methodological approach of Ecodynamics of the French researcher J. Tricart (1977) and on the operalisation proposal advocated by the Brazilian J. Ross (1994), related to the Potential and Emerging Ecodynamic Units, grounded in the Relief s Dissection Index or the topographic roughness, soil, rainfall and land use/vegetal cover. Under a quantitative perspective, the results obtained from the analysis of the watershed can be divided into classes of potential fragility: around 2.613,0 km² of low intensity, 5.188,4 km² of medium intensity and 2.585,5 km² of high intensity. Concerning the emerging fragility, the results are close to 2.212,0 km² of low intensity, 6.191,23 km² of medium intensity and 2.062,34 km² of high intensity. In the case of the watershed in question, the environmental degradation is particularly effective in the areas more dissected, where the ecological conditions, in synergy the environmental degradation, prevent the regeneration of vegetation when arises an opportunity for the (re)establishment of its equilibrium tenuous. The collected data is relevant for the territorial and environmental planning of the watershed, once we can still verify a close association of the cities on the central area of desertification with the areas of high environmental instability/fragility. This is an important tool to the understanding of the potential susceptibility of the natural and anthropic environments related to the advance and/or intensification of the erosion process, rock falls, mass movements, among other phenomena inside the potential unstable areas. From this perspective, the continuity of this research becomes extremely important to the understanding and arrangement of the process, together with the engendering and sustainability of the system in its totality; in narrow correlation because their potentialities, constraints and alternatives on Seridó River watershed, and in all the semi-arid region with similar characteristics
