As Mulheres e as Muralhas do Patriarcado e do Capitalismo: Terceirização e Precarização do Trabalho no Sistema do Capital

Our dissertation deals with the material living conditions of women workers and the relations of the wage who undergo in the hospital scope, taking as the locus of empirical research the Hospital Dr. João Machado, located in Natal / RN. Its purpose is to analyze the main implications of precarious work contracts in the economic and social dimensions from life of workers, explaining the main conditionings. The majority presence of women in wage relations not only in the hospital service, as well as in the service sector in general has motivated us to appreciation of the form of participation of women in health services and, in particular, at the hospital space. From the critical dialectical method, through processes of successive approximations to the reality, we analyze the patriarchal system of social relations and their repercussions for the Social and Sexual Division of Labor in the context of contemporary capitalist society, explaining the determinants of inequality, founded in social relations of sex, to the predominance of women in the hospital service and unveiling these participation trends in the labor market. The analyzes are based on bibliographic research - theoretical and methodological basis of research - combined with reflections that emerged from the field. The systematized and analyzed information reveal the uniqueness of the current social and economic situation of workers women with ties outsourced, paradoxically expresses on the expansion of the insertion in universe of labor, in overexploitation, in the precariousness of work and living conditions and persistent inequality in and in the social relations and in relations between the sexes

Assistência social ao idoso no município de Natal na proteção social básica: identificando demandas e desafios

Over the past decades, starting mainly in the 1960s, the number of elderly has grown in the country and an aging population is considered a remarkable global phenomenon. Given the speed of this process, this growth has produced different implications for the structure of the social, economic and cultural societies and, as such, constitutes new challenges for public policy, and particularly for the Brazilian social assistance policy. Considering the significant increase aging population in Natal and the challenges of social welfare policy, this research aims to identify and analyze the demands and challenges of Social Assistance Policy in the city of Natal / RN, in particular the access of the elderly to social protection basic in the Reference Centers of Social Assistance. This research uses a critical dialectical method, and the methodological procedures that guided the study: the bibliographical research, documentary and field as well as systematic observation. Some initial questions were important to guide this work: What are the demands that come to CRAS the elderly population? What are the answers to these demands by the Basic Social Protection? How this CRAS has implemented social protection responses to these demands as rights guarantee the elderly population? The services offered by CRAS meets user needs? To get the results of this research, bibliographic sources were used, documentary and observation for four (4) CRAS of different district areas of the city of Natal. The results of this research show that basic social protection is quite fragile, leaving part of the population at risk and social vulnerability still without attention due to several factors, including the reduced technical team and the impossibility of service to all neighborhoods referenced by CRAS in the respective zones, and 50% of elderly assisted arising from spontaneous demands.

Reinternações psiquiátricas no Rio Grande do Norte: implicações e impacto das novas estratégias de atenção à saúde mental

The Brazilian Psychiatric Reform based on the desinstitucionalization of the assistance, translated to the emphasis on community/territorial treatment and in the social inclusion of the mental suffering, promoted advances in the psychiatric restructuring. In the Rio Grande do Norte (RN), we can enumerate as advances of the Brazilian Psychiatric Reform the expansion of the mental health care chain and the implementation of some strategies that, together, aims to further the psychosocial attention of the individual with psych suffering and to reduce the indices of psychiatrics readmissions in the state. In the current Brazilian‟s mental health situation we were interesting in answered the following question: what the impact of the substitutes services‟ extension in the revolving door phenomenon? This search aims to analyze the revolving door phenomenon occurrences based on the news strategies of mental health care in the Rio Grande do Norte. This is a descriptive-exploratory study with a qualitative approach, oriented by the theoretical framework of critical-dialectical approach about the Brazilian Psychiatric Reform and using the thematic oral history as method of information collects. The search was realized on the Hospital João Machado (HJM), estate reference in psychiatric treatment, and the participants was 20 professionals that work on it. The collection of information had started after the approval of the UFRN Research Ethics Committee with the opinion number 216/2011 and CAAE number 0021.0.051.000-11 and was realized using the direct observation and semi-structured interview. The study‟s results were categorized in two categories and five subcategories of analysis. CATEGORY 1) Current situation of the mental health care chain in the RN, with the subcategories: 1.1 Impact of the new services of mental health care in the revolving door phenomenon in the RN; 1.2 Implications of the new services of mental health care in assisting user to the HJM; 1.3 Issues the permeate the mental health care chain in the RN. CATEORY 2) Main causes of the revolving door phenomenon in HJM, with the categories: 2.1 Family problems; 2.2 Lack of assistance after discharge from psychiatric hospital. In summary, we conclude that the extension of the mental health care chain contributed for the reduction of the psychiatrics re-hospitalization‟s indices in RN. However, we realized that territorial services of mental health care are not the only responsible for the revolving door phenomenon. Factors as family problems and the disarticulation of the assistance after the discharge from hospital influence on the perpetuation of hospitalizations and re-hospitalizations in the local scenario. To study the revolving door phenomenon that occur in the psychiatrics‟ assistance considering the news strategies of mental health care allowed us to approach the advances and challenges brought by the RPb and by the desinstitucionatization in the state, indicating the need for further discussions and problem-solving strategies of psychosocial care.

Estudo de propriedades críticas em sistemas complexos: método de procura automática em sistemas tipo Ising e percolação de longo alcance

The new technique for automatic search of the order parameters and critical properties is applied to several well-know physical systems, testing the efficiency of such a procedure, in order to apply it for complex systems in general. The automatic-search method is combined with Monte Carlo simulations, which makes use of a given dynamical rule for the time evolution of the system. In the problems inves¬tigated, the Metropolis and Glauber dynamics produced essentially equivalent results. We present a brief introduction to critical phenomena and phase transitions. We describe the automatic-search method and discuss some previous works, where the method has been applied successfully. We apply the method for the ferromagnetic fsing model, computing the critical fron¬tiers and the magnetization exponent (3 for several geometric lattices. We also apply the method for the site-diluted ferromagnetic Ising model on a square lattice, computing its critical frontier, as well as the magnetization exponent f3 and the susceptibility exponent 7. We verify that the universality class of the system remains unchanged when the site dilution is introduced. We study the problem of long-range bond percolation in a diluted linear chain and discuss the non-extensivity questions inherent to long-range-interaction systems. Finally we present our conclusions and possible extensions of this work

Formal verification of PLC programs using the B Method

PLCs (acronym for Programmable Logic Controllers) perform control operations, receiving information from the environment, processing it and modifying this same environment according to the results produced. They are commonly used in industry in several applications, from mass transport to petroleum industry. As the complexity of these applications increase, and as various are safety critical, a necessity for ensuring that they are reliable arouses. Testing and simulation are the de-facto methods used in the industry to do so, but they can leave flaws undiscovered. Formal methods can provide more confidence in an application s safety, once they permit their mathematical verification. We make use of the B Method, which has been successfully applied in the formal verification of industrial systems, is supported by several tools and can handle decomposition, refinement, and verification of correctness according to the specification. The method we developed and present in this work automatically generates B models from PLC programs and verify them in terms of safety constraints, manually derived from the system requirements. The scope of our method is the PLC programming languages presented in the IEC 61131-3 standard, although we are also able to verify programs not fully compliant with the standard. Our approach aims to ease the integration of formal methods in the industry through the abbreviation of the effort to perform formal verification in PLCs

Identidades coletivas de estudiosos da linguagem no currículo lattes: docência, pertença social e capital cultural-acadêmico

The discussion involving the identity of social actors has taken place for some years, however, it has become significant for the discourse studies over the last years due to the fragmentation of postmodern actors. Understanding the identity as a symbolic concept that can aid in the detection of certain realities - a kind of mechanism / a magnifying glass (MERLUCCI, 1985) - you can check the linguistic materiality of the introductory text of the lattes resume as a adequate place for the formation of collective identities . The aim of this dissertation is to reflect, in a time of postmodernity, through the lattes introductory curriculum texts, the collective identities of the language researchers are portrayed in discursive and social practices based on the accumulation of cultural and academic capital. For analysis, surrounding the indisciplinary posture in Applied Linguistics (MOITA-LOPES, 2006), the descriptive / interpretive methodology was used (MAGALHÃES, 2001). Whereas the study method and the social theory, as state reasons of the research makes use of the Sociological Approach and Communicational Discourse, chain linked to the assumptions of Critical Discourse Analysis (PEDROSA, 2012a). The corpus is constituted of twenty-seven introductory texts from the lattes curriculum of language researchers, connected to three institutions of higher learning in Sergipe. After the collection, on the lattes platform, and the numbering of the curriculum in order to achieve the research objective, we performed the analysis based on three identity themes: teaching, social belonging (BAJOIT, 2006; DESCHAMPS; MOLINER, 2009) and the accumulation of academic-cultural capital (BOURDIEU, 2004; HEY, 2008). The data show that the texts of the lattes curriculum are based on hegemonic and ideological principals, referring to the accumulation of academic assets, the valuation of actors and the hierarchical positions, recognized and ratified by couples who socialize among themselves Right now, the research allows us to infer that, in postmodernity, some collective identity assumptions, contribute to the understanding of the academic reality, around the the lattes curriculum.

Avaliação de polimorfismos funcionais nos genes de reparo XRCC1, APEX1, XPD e XPF em carcinomas de células escamosas orais

Base excision repair (BER) and nucleotide excision repair (NER) pathways play critical role in maintaining genome integrity. Polymorphisms in BER and NER genes which modulate the DNA repair capacity may affect the susceptibility and prognosis of oral cancer. This study was conducted with genomic DNA from 92 patients with oral squamous cell carcinomas (OSCC) and 130 controls. The cases were followed up to explore the associations between BER and NER genes polymorphisms and the risk and prognosis of OSCC. Four single-nucleotide polymorphisms (SNPs) in XRCC1 (rs25487), APEX1 (rs1130409), XPD (rs13181) and XPF (rs1799797) genes were tested by polymerase chain reaction – quantitative real time method. The GraphPad Prism version 6.0.1 statistical software was applied for statistical analysis of association. Odds ratio (OR), hazard ratio (HR), and their 95 % confidence intervals (CIs) were calculated by logistic regression. Kaplan-Meier curve and Cox proportional hazard model were used for prognostic analysis. The presence of polymorphic variants in XRCC1, APEX1, XPD and XPF genes were not associated with an increased risk of OSCC. Gene-environment interactions with smoking were not significant for any polymorphism. The presence of polymorphic variants of the XPD gene in association with alcohol consumption conferred an increased risk of 1.86 (95% CI: 0.86 – 4.01, p=0.03) for OSCC. Only APEX1 was associated with decreased specific survival (HR 3.94, 95% CI: 1.31 – 11.88, p=0.01). These results suggest an interaction between polymorphic variants of the XPF gene and alcohol consumption. Additionally APEX1 may represent a prognostic marker for OSCC.
