A organização sindical dos assistentes sociais no Brasil: dilemas e desafios contemporâneos

This paper discusses the dilemmas and challenges of the union of social workers in contemporary Brazil. The study is supported by the theme in a literature search, especially productions that deal with the trade union movement of workers in the brazilian reality, as well as on field research, which consisted of interviews with national trade union leaders of the CUT and CONLUTA as also representatives of national organizations representing the professional category of social workers, notably CFESS, ABEPSS ENESSO and a labor union and the national category, FENAS. The analysis of the object is oriented in the perspective of totality, considering its founding and contradictory aspects of the current socio-historical dynamics. The inflections occurred in the razilian Labor Movement in the early 1990s, during which the offensive of capital, characterized by the fusion of flexible accumulation and the dictates of neoliberal policy is established in the country, caused a profound shock in life and organization of the class working. The major repercussions of this process are evident today in the form of defensive organization of trade union struggles, notably fragile and fragmented. In the case of the category of social workers is symptomatic of the political backlash, experienced the process of reopening their unions and the creation of FENAS. This definition, part of the analysis that considers more strategic perspective of class organization, corporate antiunionism of the mass of the 1980s, built, largely, by category and expressed by the extinction of their union and unification to the broader struggles of workers with transition to unionization by industry. Given this reality, we analyze the performance of the political perspectives of the brazilian labor movement, from the characterization of organizational arrangements for trade union struggles and situate this process, the motion to reopen union of social workers, from the emergence of FENAS. Therefore, we aimed to identify the particular and the ideological and political perspectives that make up the dilemma of the trade union movement from this reopening, as corresponds to a political trend, largely, overcome within the brazilian social work

Movimentos sociais e organização popular em Natal-RN: enquanto morar for privilégio...

To the extent that the expansion of cities is increasingly pushing and segregating the working class to outlying areas, devoid of services and infrastructure, the urban space is also important as a space in the class struggle, and in this direction, the this study aims to analyze the political organization of urban social movements and popular organizations existing in Natal-RN, nowadays, in their process of struggle for social rights, with emphasis on the right to the city. With this dimension, we appropriate the contributions of historical and dialectical materialism because we believe that this benchmark enables the understanding of the processes of collective organization and a critical perspective of totality, going beyond its immediate appearance. For production data conducted literature, documentary and field, through semi-structured interviews recorded with (the) mapped leaders of organizations in our survey, as well as advisory bodies to the movements studied. The results of the study allowed us to characterize the action of the political movements in urban Christmas struggle for recognition and guarantee of the right to the city and seize the advances and obstacles in the process of intervention of social movements and popular organizations existing in Natal, highlighting dilemmas and contradictions underlie the processes of organization and mobilization in the contemporary period. Thus, we conclude that the Natal territory, as in contemporary Brazil, the urban and political action movements that show the public scene and intertwine necessarily relate to historical trend that has been performing since the 1990s, when the country entered a period marked by a new bourgeois offensive

O que há de real e de irreal com o realismo: Searle versus Rorty

O texto fala a respeito do debate entre Searle e Rorty sobre irracionalismo de Rorty. Ele tenta mostrar que a posição de Rorty está fora do campo realismo versus anti-realismo e o irracionalismo não é um bom adjetivo. Searle estaria sobre uma linha incorreta em sua abordagem do tema da verdade em Rorty.

A necessidade do acaso: um convite ao diálogo filosófico

Um posicionamento filosófico realista que não coloque em dúvida a inteligibilidade do universo ao qual investiga e não se pretenda detentor de qualquer privilégio para alcançar a verdade admite a falibilidade de qualquer representação da realidade, não vendo motivo para fugir ao diálogo com aqueles que propõem explicações diferentes das suas, mesmo que por vezes com elas conflitantes.

Romance e realidade na ficção brasileira contemporânea

Este trabalho é uma reflexão sobre a representação do real no romance Inferno provisório, de Luiz Ruffato, considerando as proposições de Claudio Magris acerca da forma romanesca moderna e sua possível transformação nas últimas décadas. O objetivo é questionar de que modo o projeto estético do romance incorpora uma visão em profundidade do real, originando um princípio ético de análise e crítica da sociedade contemporânea.

Knowledge Representation and Orthophemism: A Reflection Aiming to a Concept

Characteristics of speech, especially figures of speech, are used by specific communities or domains, and, in this way, reflect their identities through their choice of vocabulary. This topic should be an object of study in the context of knowledge representation once it deals with different contexts of production of documents. This study aims to explore the dimensions of the concepts of euphemism, dysphemism, and orthophemism, focusing on the latter with the goal of extracting a concept which can be included in discussions about subject analysis and indexing. Euphemism is used as an alternative to a non-preferred expression or as an alternative to an offensive attribution-to avoid potential offense taken by the listener or by other persons, for instance, pass away. Dysphemism, on the other hand, is used by speakers to talk about people and things that frustrate and annoy them-their choice of language indicates disapproval and the topic is therefore denigrated, humiliated, or degraded, for instance, kick the bucket. While euphemism tries to make something sound better, dysphemism tries to make something sound worse. Orthophemism (Allan and Burridge 2006) is also used as an alternative to expressions, but it is a preferred, formal, and direct language of expression when representing an object or a situation, for instance, die. This paper suggests that the comprehension and use of such concepts could support the following issues: possible contributions from linguistics and terminology to subject analysis as demonstrated by Talamo et al. (1992); decrease of polysemy and ambiguity of terms used to represent certain topics of documents; and construction and evaluation of indexing languages. The concept of orthophemism can also serves to support associative relationships in the context of subject analysis, indexing, and even information retrieval related to more specific requests.

Thermodynamic analysis of direct steam reforming of ethanol in molten carbonate fuel cell

Fuel cell as MCFC (molten carbonate fuel cell) operate at high temperatures, and due to this issue, cogeneration processes may be performed, sending heat for own process or other purposes as steam generation in an industry. The use of ethanol for this purpose is one of the best options because this is a renewable and less environmentally offensive fuel, and cheaper than oil-derived hydrocarbons (in the case of Brazil). In the same country, because of technical, environmental and economic advantages, the use of ethanol by steam reforming process have been the most investigated process. The objective of this study is to show a thermodynamic analysis of steam reforming of ethanol, to determine the best thermodynamic conditions where are produced the highest volumes of products, making possible a higher production of energy, that is, a most-efficient use of resources. To attain this objective, mass and energy balances are performed. Equilibrium constants and advance degrees are calculated to get the best thermodynamic conditions to attain higher reforming efficiency and, hence, higher electric efficiency, using the Nernst equation. The advance degree of reforming increases when the operation temperature also increases and when the operation pressure decreases. But at atmospheric pressure (1 atm), the advance degree tends to the stability in temperatures above 700°C, that is, the volume of supplemental production of reforming products is very small for the high use of energy resources necessary. Reactants and products of the steam-reforming of ethanol that weren't used may be used for the reforming. The use of non-used ethanol is also suggested for heating of reactants before reforming. The results show the behavior of MCFC. The current density, at same tension, is higher at 700°C than other studied temperatures as 600 and 650°C. This fact occurs due to smaller use of hydrogen at lower temperatures that varies between 46.8 and 58.9% in temperatures between 600 and 700°C. The higher calculated current density is 280 mA/cm 2. The power density increases when the volume of ethanol to be used also increases due to higher production of hydrogen. The highest produced power at 190 mW/cm 2 is 99.8, 109.8 and 113.7 mW/cm2 for 873, 923 and 973K, respectively. The thermodynamic efficiency has the objective to show the connection among operational conditions and energetic factors, which are some parameters that describes a process of internal steam reforming of ethanol.

Physical-chemical and thermodynamic analyses of steam reforming of ethanol to hydrogen production

The steam reforming is one of most utilized process of hydrogen production because of its high production efficiencies and its technological maturity. The use of ethanol for this purpose is a interesting option because this is a renewable and less environmentally offensive fuel. The objective of this study is evaluate the physical-chemical, thermodynamic and environmental analyses of steam reforming of ethanol. whose objective is to produce 0.7 Nm3/h of hydrogen to be used by a PEMFC of l kW. In this physical-chemical analysis, a global reaction of ethanol was considered. That is, the superheated ethanol and steam, at high temperatures, react to produce hydrogen and carbon dioxide. Beyond it's the simplest form to study the steam reforming of ethanol to hydrogen production, it's the case where occurs the highest production of hydrogen (the product to be used by fuel cells) and carbon dioxide, to be eliminated. But this reaction isn't real and depends greatly on the thermodynamic conditions of reforming, technical features of reformer system and catalysts. Other products generally formed (but not investigated in this study) are methane, carbon monoxide, among others. It was observed that the products is commonly produced in the moment when the reaction attains temperatures about 206°C (below this temperature, the reaction trend to the reaetants, that is, from hydrogen and carbon dioxide to steam and ethanol) and the advance degree of this reaction increases when the temperature of reaction also increases and when its pressure decreases. It's suggested reactions at about 600°C or higher. However, when the temperature attains 700°C, the stability of this reaction is occurred, that is, the production of reaction productions attains to the limit, that is the highest possible production. In temperatures above 700°C, the use of energy is very high for produce more products, having higher costs of production that the suggested temperature. The indicated pressure is 1 atm., a value that allows a desirable economy of energy that would also be used for pressurization or depressurization of steam reformer. In exergetic analysis, it's seem that the lower irreversibililies occur when the pressure of reactions are lower. However, the temperature changes don't affect significantly the irreversibilites. Utilizing the obtained results from this analysis, it was concluded that the best thermodynamic conditions for steam reforming of ethanol is the same conditions suggested in the physical-chemical analysis. The exergetic and first law efficiencies are high on the thermodynamie conditions studied.

José de Alencar e o teatro: Um romântico realista

José de Alencar (1829-1877) is more known by the public reader by his novels. However, Alencar was also one of the most famous Brazilian playwright of nineteenth century's second half, with a work marked by successes, failures and controversies. This article intends to study an important part of his work, especially the beginning of his actions towards the still incipient Brazilian theatre in his chronic Ao correr da pena, as well as the analysis of two plays, O demônio familiar (1857), and As asas de um anjo (1857). These works not only show his public's success and failure, but also his flair for controversy. By using as theoretical basis João Roberto Faria and Martin Esslin, as well as other literary and theatre theorists, it will be shown that, although he defended French realism in theatre and used proceedings related to the genre, such realism, on his plays, was mixed with romantic solutions what made his work unique.
