O Processo de revisão do benefício de prestação continuada-BPC: uma lógica de exclusão ou inclusão social

This research comprises a study about the social assessment performed by the Social Worker in the review process of the Benefit of Continued Installment. The Benefit of Continued Installment was implemented in 1996 and guarantees a minimum salary to the deficiency person and to an elder with sixty five years or more and that proves not to have ways to support neither himself/herself nor his/her own family. It is a demand to include in the BPC that the maximum income of a family does not exceed ¼ of minimum salary and that every two years this benefit to be revised to evaluate its continuity based in its original conditions. This study was carried out in the municipality of Natal/RN, with thirteen social workers, being the collection of data performed through interviews and social assessments of the users that count with the benefit. The results show that the users selected by the criterion of the income, present a profile of poverty and deprivations demonstrated through several situations survived in its daily life, indicative of vulnerability. It was demonstrated that the Social workers has relative autonomy in the evaluations along with the users and that it denotes the necessity of inclusion. However, by following the imposed criteria, it corroborates with the logic of exclusion. So, it is identified in the Municipality of Natal/RN, following the orientation given the politics of social work at national level, the implementation of revision of the BPC, for the social workers, from rigorous processes of selection and exclusions

O Desenvolvimento local sustentável no semi-árido nordestino: um estudo de caso na comunidade de mirandas, Caraúbas/RN

Brazil s semi-arid region is an immense territory characterized by a mosaic of natural environments and human settlements. Inside this multifaceted framework, there are problems that are specific to the region (the water resources situation, for example) while others are more universal (such as the inequality between men and women). The circumstances that give rise to these problems are complex and require a holistic view so that our understanding can go beyond the simple concept that this is a problem region . The semi-arid must be perceived as a viable area in need of a new analysis, taking into account its successes, limitations, challenges and the strategic public policy framework that guarantees its sustainable development. The dissertation analyzes, from a sustainable local development perspective, the experience of the Northeastern Brazil Groundwater Project (PROASNE), carried out from 2001 to 2003, in partnership with the Waters and Sewers Company of Rio Grande do Norte (CAERN) in the rural community of Mirandas, municipality of Caraúbas/RN, situated in the middle of the northeastern Brazil semi-arid region

Projeto de Sistemas Integrados de Propósito Geral Baseados em Redes em Chip Expandindo as Funcionalidades dos Roteadores para Execução de Operações: A plataforma IPNoSys

It bet on the next generation of computers as architecture with multiple processors and/or multicore processors. In this sense there are challenges related to features interconnection, operating frequency, the area on chip, power dissipation, performance and programmability. The mechanism of interconnection and communication it was considered ideal for this type of architecture are the networks-on-chip, due its scalability, reusability and intrinsic parallelism. The networks-on-chip communication is accomplished by transmitting packets that carry data and instructions that represent requests and responses between the processing elements interconnected by the network. The transmission of packets is accomplished as in a pipeline between the routers in the network, from source to destination of the communication, even allowing simultaneous communications between pairs of different sources and destinations. From this fact, it is proposed to transform the entire infrastructure communication of network-on-chip, using the routing mechanisms, arbitration and storage, in a parallel processing system for high performance. In this proposal, the packages are formed by instructions and data that represent the applications, which are executed on routers as well as they are transmitted, using the pipeline and parallel communication transmissions. In contrast, traditional processors are not used, but only single cores that control the access to memory. An implementation of this idea is called IPNoSys (Integrated Processing NoC System), which has an own programming model and a routing algorithm that guarantees the execution of all instructions in the packets, preventing situations of deadlock, livelock and starvation. This architecture provides mechanisms for input and output, interruption and operating system support. As proof of concept was developed a programming environment and a simulator for this architecture in SystemC, which allows configuration of various parameters and to obtain several results to evaluate it

Em direção a uma representação para equações algébricas :uma lógica equacional local

The intervalar arithmetic well-known as arithmetic of Moore, doesn't possess the same properties of the real numbers, and for this reason, it is confronted with a problem of operative nature, when we want to solve intervalar equations as extension of real equations by the usual equality and of the intervalar arithmetic, for this not to possess the inverse addictive, as well as, the property of the distributivity of the multiplication for the sum doesn t be valid for any triplet of intervals. The lack of those properties disables the use of equacional logic, so much for the resolution of an intervalar equation using the same, as for a representation of a real equation, and still, for the algebraic verification of properties of a computational system, whose data are real numbers represented by intervals. However, with the notion of order of information and of approach on intervals, introduced by Acióly[6] in 1991, the idea of an intervalar equation appears to represent a real equation satisfactorily, since the terms of the intervalar equation carry the information about the solution of the real equation. In 1999, Santiago proposed the notion of simple equality and, later on, local equality for intervals [8] and [33]. Based on that idea, this dissertation extends Santiago's local groups for local algebras, following the idea of Σ-algebras according to (Hennessy[31], 1988) and (Santiago[7], 1995). One of the contributions of this dissertation, is the theorem 5.1.3.2 that it guarantees that, when deducing a local Σ-equation E t t in the proposed system SDedLoc(E), the interpretations of t and t' will be locally the same in any local Σ-algebra that satisfies the group of fixed equations local E, whenever t and t have meaning in A. This assures to a kind of safety between the local equacional logic and the local algebras

Medidas de associação em estudo transversal com delineamento complexo: razão de chances e razão de prevalência

O objetivo deste estudo foi apresentar e discutir a utilização das medidas de associação: razão de chances e razão de prevalências, em dados obtidos de estudo transversal realizado em 2001-2002, utilizando-se amostra estratificada por conglomerados em dois estágios (n=1.958). As razões de chances e razões de prevalências foram estimadas por meio de regressão logística não condicional e regressão de Poisson, respectivamente, utilizando-se o pacote estatístico Stata 7.0. Intervalos de confiança e efeitos do desenho foram considerados na avaliação da precisão das estimativas. Dois desfechos do estudo transversal com diferentes níveis de prevalência foram avaliados: vacinação contra influenza (66,1%) e doença pulmonar referida (6,9%). Na situação em que a prevalência foi alta, as estimativas das razões de prevalência foram mais conservadoras com intervalos de confiança menores. Na avaliação do desfecho de baixa prevalência, não se observaram grandes diferenças numéricas entre as estimações das razões de chances e razões de prevalência e erros-padrão obtidos por uma ou outra técnica. O efeito do desenho maior que a unidade indicou que a amostragem complexa, em ambos os casos, aumentou da variância das estimativas. Cabe ao pesquisador a escolha da técnica e do estimador mais adequado ao seu objeto de estudo, permanecendo a escolha no âmbito epidemiológico.

Reply to comment on 'Quantization rules for bound states in quantum wells'

In this reply to the comment on 'Quantization rules for bound states in quantum wells' we point out some interesting differences between the supersymmetric Wentzel-Kramers-Brillouin (WKB) quantization rule and a matrix generalization of usual WKB (mWKB) and Bohr-Sommerfeld (mBS) quantization rules suggested by us. There are certain advantages in each of the supersymmetric WKB (SWKB), mWKB and mBS quantization rules. Depending on the quantum well, one of these could be more useful than the other and it is premature to claim unconditional superiority of SWKB over mWKB and mBS quantization rules.

Trabalho industrial e câncer de pulmão

Com base em populações hospitalares, foram entrevistados 316 casos e 536 controles para obtenção de informações sobre histórias de trabalho, tabagismo, tabagismo passivo, ocorrência de outros cânceres na família, migração e situação socioeconômica. Os entrevistadores utilizaram um questionário padronizado. Casos e controles foram emparelhados por hospital, sexo e idade. O estudo foi desenvolvido entre 1º de julho de 1990 e 31 de janeiro de 1991 em 14 hospitais da Região Metropolitana de São Paulo, SP (Brasil). Foi elaborada uma classificação por escores como forma de ordenar os indivíduos estudados segundo suas histórias de exposições ocupacionais a cancerígenos, conhecidos para o pulmão, acumulando informações sobre a exposição nos locais de trabalho durante a vida, considerando o tipo de atividade, setor de trabalho e tempo em cada emprego. A análise de regressão logística não-condicional mostrou odds ratio: 1,97 (95% IC: 1,52 a 2,55) para os trabalhadores com maiores escores de exposição. Os resultados permitiram inferir que trabalhadores ligados aos setores de produção de diferentes ramos industriais têm duas vezes o risco de desenvolverem neoplasia pulmonar quando comparados aos trabalhadores envolvidos em atividades não-industriais.

Designing a modified Hopfield network to solve an Economic Dispatch problem with nonlinear cost function

Economic Dispatch (ED) problems have recently been solved by artificial neural networks approaches. In most of these dispatch models, the cost function must be linear or quadratic. Therefore, functions that have several minimum points represent a problem to the simulation since these approaches have not accepted nonlinear cost function. Another drawback pointed out in the literature is that some of these neural approaches fail to converge efficiently towards feasible equilibrium points. This paper discusses the application of a modified Hopfield architecture for solving ED problems defined by nonlinear cost function. The internal parameters of the neural network adopted here are computed using the valid-subspace technique, which guarantees convergence to equilibrium points that represent a solution for the ED problem. Simulation results and a comparative analysis involving a 3-bus test system are presented to illustrate efficiency of the proposed approach.

Universal aspects of Efimov states and light halo nuclei

The parametric region in the plane defined by the ratios of the energies of the subsystems and the three-body ground state, in which Efimov states can exist, is determined. We use a renormalizable model that guarantees the general validity of our results in the context of short-range interactions. The experimental data for one-and two-neutron separation energies, implies that among the halo nuclei candidates, only 20C has a possible Efimov state, with an estimated energy less than 14 KeV below the scattering threshold.

Virtual states of light non-Borromean halo nuclei

It is shown that three-body non-Borromean halo nuclei like 12Be, 18C, 20C, considered as neutron-neutron-core systems, have p-wave virtual states with energy of about 1.7 times the corresponding neutron-core binding energy. We use a renormalizable model that guarantees the general validity of our results in the context of short range interactions.

Justiça penal autoritária e consolidação do estado punitivo no Brasil

The Brazilian democratic transition, still underway today, has run up against enormous difficulty in incorporating penal action. Or, put in yet stronger terms, we could say that the boundaries of democratization processes, delineated through the action of that sector of the State, reveal the possibility that the juridical field remains immune to democratizing change. Although prevailing discourse among law professionals asserts that Penal Justice is undergoing democratization, what we have observed in practice is a strong resistance within the juridical field to assuming political responsibilities within the consolidation of democracy. This article reports analyses and conclusions formulated through observation of the Brazilian penal justice system that gave origin to the thesis entitled Penal Justice in Brazil today: democratic discourse, authoritarian practice. The research sought to reflect on contemporary criminal justice policy, which has been guided by the widening of repression and the continued use of incarceration. Such policy, carried out in Brazil since the beginning of the 1985 political opening has adjusted itself to the liberal project that is also currently underway in the country, as well as in almost the entire Western capitalist world. As we can observe, Penal Justice, even during the execution of sentences, operates in authoritarian and exclusive ways, suppressing the rights guaranteed by law to those who have been sentenced and adopting extremely repressive forms as demonstrated by the extremely sparse benefits that it concedes. Thus, in Brazil, criminality has generally been responded through severe sentences, reflected in the absence of guarantees of constitutional rights and ample recourse to incarceration. In this vein, our contemporary democratic governments have frequently adopted a punitive stance that seeks to reaffirm the State's aptitudes for punishing and controlling criminality. © 2009 Revista de Sociologia e Política.

Comparison of methods for the detection of biofilm production in coagulase-negative staphylococci

Background: The ability of biofilm formation seems to play an essential role in the virulence of coagulase-negative staphylococci (CNS). The most clearly characterized component of staphylococcal biofilms is the polysaccharide intercellular adhesin (PIA) encoded by the icaADBC operon. Biofilm production was studied in 80 coagulase-negative staphylococci (CNS) strains isolated from clinical specimens of newborns with infection hospitalized at the Neonatal Unit of the University Hospital, Faculty of Medicine of Botucatu, and in 20 isolates obtained from the nares of healthy individuals without signs of infection. The objective was to compare three phenotypic methods with the detection of the icaA, icaD and icaC genes by PCR. Findings: Among the 100 CNS isolates studied, 82% tested positive by PCR, 82% by the tube test, 81% by the TCP assay, and 73% by the CRA method. Using PCR as a reference, the tube test showed the best correlation with detection of the ica genes, presenting high sensitivity and specificity. Conclusions: The tube adherence test can be indicated for the routine detection of biofilm production in CNS because of its easy application and low cost and because it guarantees reliable results with excellent sensitivity and specificity. © 2010 Cunha et al; licensee BioMed Central Ltd.
