Dificuldades de aprendizagem em estequiometria: uma proposta de ensino apoiada na modelagem

In order to learn/teach chemistry some themes are relevant, like the stoichiometry, which consists in the study of the weight ratios in the combination of elements and compounds between themselves. This is an underlying subject in the understanding/representation/forethought of chemical reactions. Considering these aspects, our study presents a modeling-based proposal to develop the content of stoichiometry with prospective chemistry teachers. With this aim, we have made a review of literature, which we considered when tried to identify the learning difficulties using both quizzes and pedagogical tests, and then, from those difficulties we could propose a teaching unit for this concept and, consequently the evaluation of our proposal. The participants were chemistry undergraduates at the Universidade Federal do Rio Grande do Norte (UFRN) from assorted levels. As a methodological framework, we rely on the discursive textual analysis to characterize the speech of participants. As main results we observed ideas of appearance or disappearance of matter during chemical transformations, disregard of stoichiometric proportions when using drawings to represent the microscopic level of a reaction and confusion between the magnitude amount of matter and other magnitudes such as mass and volume. The final product is a sequence of instruction, based on the modeling previous research literature , with the goal of improving students ability to articulate the macroscopic and submicroscopic levels of representation of the matter

Sensoriamento remoto hidroacústico no mapeamento de macrófitas aquáticas submersas

Macrófitas são importantes produtoras primárias do ecossistema aquático, e o desequilíbrio do ambiente pode ocasionar seu crescimento acelerado. Portanto, levantamentos de dados relacionados a macrófitas submersas são importantes para contribuir na gestão de corpos de água. Contudo, a amostragem dessa vegetação requer um enorme esforço físico. Nesse sentido, a técnica hidroacústica é apropriada para o estudo de macrófitas submersas. Assim, os objetivos deste trabalho foram avaliar os tipos de dados gerados pelo ecobatímetro e analisar como esses dados caracterizam a vegetação. Utilizou-se o ecobatímetro BioSonics DT-X acoplado a um GPS. A área de estudo é um trecho do Rio Uberaba, MG. A amostragem foi feita por meio de transectos, navegando de uma margem à outra. Depois de processar os dados, obteve-se informação a respeito de ocorrência de macrófitas submersas, profundidade, altura média das plantas, porcentagem da cobertura vegetal e posição. A partir desse conjunto de dados, foi possível extrair outras duas métricas: biovolume e altura efetiva do dossel. Os dados foram importados de um Sistema de Informação Geográfica e geraram-se mapas ilustrativos das variáveis estudadas. Além disso, quatro perfis foram selecionados para analisar a diferença entre as grandezas de representação de macrófitas. O ecobatímetro mostrou-se uma ferramenta eficaz no mapeamento de macrófitas submersas. Cada uma das medidas - altura do dossel, ECH ou biovolume - caracteriza de forma diferente a vegetação submersa. Dessa forma, a escolha do tipo de representação depende da aplicação desejada.

"Eu pensei que ia sair daqui falando inglês": um estudo sistêmico-funcional sobre papéis sociais atribuídos por alunos de um curso de Letras/Inglês

Research in the area of teacher training in English as a Foreign Language (CELANI, 2003, 2004, 2010; PAIVA, 2000, 2003, 2005; VIEIRA-ABRAHÃO, 2010) articulates the complexity of beginning teachers classroom contexts aligned with teaching language as a social and professional practice of the teacher in training. To better understand this relationship, the present study is based on a corpus of transcribed interviews and questionnaires applied to 28 undergraduate students majoring in Letters/English emphasis, at a public university located in the interior of the Western Amazon region, soliciting their opinions about the reforms made in the curriculum of this Major. Interviews and questionnaires were used as data collection instruments to trace a profile of the students organized in Group 1, with freshmen and sophomore undergraduates who are following the 2009 curriculum, and Group 2, with junior and senior undergraduates who are following the 2006 curriculum. The objectives are to identify, to characterize and to analyze the types of pronouns, roles and social actors represented in the opinions of these students in relation to their teacher training curriculum. The theoretical support focuses on the challenge of historical and contemporary routes from English teachers initial education programs (MAGALHÃES; LIBERALLI, 2009; PAVAN; SILVA, 2010; ALVAREZ, 2010; VIANA, 2011; PAVAN, 2012). Our theoretical perspective is based on the Systemic Functional Grammar of Halliday (1994), Halliday and Hasan (1989), Halliday and Matthiessen (2004), Eggins (1994; 2004) and Thompson (2004). We focus on the concept of the Interpersonal meaning, specifically regarding the roles articulated in the studies by Delu (1991), Thompson and Thetela (1995), and in the Portuguese language such as Ramos (1997), Silva (2006) and Cabral (2009). Moreover, we ascribe van Leeuwen s (1997; 2003) theory of Representation of Social Actors as a theoretical framework in order to identify the sociological aspect of social actors represented in the students discourse. Within this scenario, the analysis unfolds on three levels: grammatical (pronouns), semantic (roles), and discursive (social actors). For the analysis of interpersonal realizations present in the students opinions, we use the computational program WordSmith Tools (SCOTT, 2010) and its applications Wordlist and Concord to quantify the occurrences of the pronouns I, You and They, which characterize the roles and social actors of the corpus. The results show that the students assigned the following roles to themselves: (i) apprentice to express their initial process of English language learning; (ii) freshman to reveal their choice of Major in Letters/English emphasis; (iii) future teacher to relate their expectations towards a practicing professional. To assign the roles to professors in the major, the students used the metaphor of modality (I think) to indicate the relationship of teacher training, while they are in the role of a student and as a future teacher. From these evidences the representation of the students as social actors emerges in roles such as: (i) active roles; (ii) passive roles and (iii) personalized roles. The social actors represented in the opinions of the students reflect the inclusion of these roles assigned to the actions expressed about their experiences and expectations derived from their teacher training classroom

O ensaio jornalístico na revista Veja: uma análise multidimensional

This work has as objective generality to make a multidimensional analysis in the genre journalistic assay, communicative genre that, beyond complex and multimodal, presents hybrid characteristics. Specifically, with the intention to propose defining criteria of the cited genre, this research looks for to establish differences and similarities between the assay and other genres of the same sphere, from the description and interpretation of used multimodal resources. The analysis of the formal, schematical and rhetorical resources identified in the formatting of the journalistic assay sample that the analyses are supported in the socio-semiotic and socio-rhetorical approaches. In the formal dimension, we contemplate elements that constitute design of the text, including the forms of representation from the typography, the colors, images, as well as the aspects communicative-linguistics: the modalization indices, the communicative operators and the category time; in the schematical dimension, we present the organizational structure, considering the rhetorical movements postulates for Swales (1990) and in the rhetorical dimension we observe the categories: who writes, for who it writes, on what it writes and where writes. The adopted methodologicals postulates are of qualitative nature and the procedure is documentary, data that in we are valid them written texts of this genre as analysis object. Corpus it is constituted by a composed sample for 14 extracted texts of a set of 173 propagated journalistic assays weekly for the magazine Veja, in the period between August of 2004 and January of 2008. The analysis of the data showed that the journalistic assay, object of this study, materializes through multiple symbolic representations and multiple subjects that turn since a small episode of the daily facts of great social relevance in the present time, of historical and cultural nature, nationwide or international. Used for the first time by Montaigne in 1580, to assign, in saying of the proper author, written fast on its life and historical events, which could nor be remembered later , the term `assay' was enriched with other specifications, of form to enclose the one that if they call scientific assay today, academic assay, journalistic assay and other types of specific assays. These denominations have to see with the enrollment of the members of diverse of practices communities, in virtue of the multiplicity of activities carried through in these spheres. The conclusions the one that we arrive had been the following ones: 1. the discursive genre is not a pure entity, in virtue of the multiplicity of situations where the sorts if insert in the social actions; 2. the institutions define the configuration of one definitive genre, also its proper assignment, since for backwards of all discursive genre a voice exists to discipline - institutional voice, and in the case of the assays for analyzed us, the institutional voice if it presents, really, as a defining trace; 3. the journalistic assay, for its multiple symbolic representations, multiple subjects and for passing explicit or implicit opinions of its author, resembles it other genres, being able, therefore, to be inserted in a colony of opinionatives genres

Homoafetividade e abertura política em contos de Caio Fernando Abreu

This text aims to study the literary representation of homoaffectivity in short stories of Caio Fernando Abreu in the context of brazilian redemocratization, specifically in the narratives published between 1982 and 1988. To understand the relation between literature and historical context in the tales, we betake, principally, to a notion of Literature and Society, as proposed for Antonio Candido. Relating the narratives of Caio Fernando Abreu with the military dictatorship and the redemocratization processes, as well as a generational project named contraculture, we aim to verify as the search for affection for men that desire others men may be conditioned for specific socio-hystorical conditions, understanding the literary work as a privileged field of representation and comprehension of reality

Entre a fé, a obra social e a publicidade: uma análise crítica do discurso da responsabilidade social da Igreja Universal do Reino de Deus

Situated on Applied Linguistics (PENNYCOOK, 1998; MOITA LOPES, 2003, 2006, 2008, 2009), this thesis, which is inscribed in a qualitative-interpretative approach of a critical analysis perspective , lies on the speech of social responsibility and the way like that is employed in seeking for legitimacy and prestige within the neopentecostal brazilian religious field, more specifically of the Universal Church of the Kingdom of God. The general goal of this research is t reflect upon the speech on social responsibility and the rethoric of selfpromotion of the Universal Church through the role of social actors in the making of his her identities, materialized in the newspaper Folha Universal. In order to achieve that, we have conjugated, in this research, social and discursive analysis. On the linguistic-discursive approach, the research is based on the Critical Analysis of Discourse (ACD), specially in Fairclough (2001, 2003, 2006), a proposal that provides theoretical-methodological tools to investigate the language beyond the linguistic structures , that is, the discourse, social practices in which it occurs and more ample structures. Theoretical assumptions were also used of Sistemico-Functional Linguistics(LSF), matching with categories of the Transitivity System of Halliday (1994, 2004), of the forms of representation of social actors in the socioeconomic perspective by Van Leeuwen (1997, 2008) and of the Appraisal system by Martin and White (2005). As we develop the argumentation on thesobre social role of religion in this thesis, we make use of the authors such as Freston (1994), Oro (1997, 2003), Campos (1996, 1999), Mariano (1999), Meneses (2008), among several ones. We have also used a series of concepts and categories coming from the field of communication and marketing on the business social responsability and social marketing . In this area, we take as references the contributions of Bueno (2003), Fossá and Sartoretto (2003) and Zenone (2006). The corpus of the work is framed by news taken at the newspaper Folha Universal, in which are given the social responsibility actions of the church . The timeframe used was on the editions of 2010 thru 2012. Results found at he analysis of the News lead to semantic features of Assessment of Affection, Judgment and Appreciation, many times followed by Gradation, and the Attribution, one of the subsystems of the Attachment, are evidence of positive assessments for the Universal Church and its agents and make up rethorical elements which provide structure for the discourse of the Universal Church at the newspaper Folha Universal consisted of its image (style) of social responsibility . Results show that the most frequente social actors of the discourse are, on one hand, the Universal Church itself and its volunteers, famous (actors, actresses, presenters), politicians and authorities, on the other hand, the population which was helped by the Church social projects . The first group seems to be Always activated, however the second one, most of the time rather passive. These are also represented by assimilation in most of the occurrences, however the other ones by individualization and nomination entitled by honorification, except for the volunteers that are represented either as an individual, or as a group

Sujeitos e atores sociais nas representações discursivas de docentes da rede estadual de ensino em Sergipe: uma análise crítica em tempos de Ideb

According to the studies in Applied Linguistics, this thesis is based on an interdisciplinary perspective (Critical Discourse Analysis, Sociology towards Social Change, Cultural Studies and Systemic-Functional Linguistics). The overall objective of the research was to analyze the discourses of Elementary School teachers in the state of Sergipe, by means of the discursive representations of the social actors, the processes of subjectivity and their fragmented identities in the context of standardized evaluations before the requirements of globalized pedagogical practices, based on the result-based management. The critical analysis of such discourses was motivated by the rapid pace with which the demands of innovation become part of the classroom, aiming at reaching the target in what concerns the indexes of the rankings which characterize the globalized discourse of the national education management, like Ideb (Basic Education Development Index), which makes teachers change their discourses, become silent or keep resistant. The work was initially endorsed by the theoretical lines of the Critical Discourse Analysis (FAIRCLOUGH, 2001, 2006), and poses a proposal for such purpose: the ASCD Discourse Sociological and Communicative Approach (PEDROSA, 2012, 2013). This is an interpretative-qualitative study of the Critical Discourse Analysis (FAIRCLOUGH, 2001, 2003; RAMALHO ; RESENDE, 2011) and to carry it out, semi-structured interviews were used as instruments of data generation (BAUER; GASKELL, 2011; GILL, 2011). Its corpus is composed of thirteen accounts of teachers from the Elementary school who teach Portuguese and work in the fifteen schools which were chosen to be the universe of the research at the Regional Board of Education (02) in the state of Sergipe. Such narratives are related to their impressions, expectations and actions which favor the management of results to which they have to submit themselves. The analytical overview of sociological and discursive line comes from the pan-semiotic categories (Inclusion and Exclusion) which appear in the theory of Representation of Social Actors (VAN LEEUWEN, 1997, 2008). To present the processes of subjectivity of these teachers, this work is based on the socio-analytical proposal of the classification of the subjects, which stems from the individual s work in the Gestão Relacional de Si , which comes from the Applied Sociology (towards) Social Change (BAJOIT, 2006, 2009). The discursive analyses were guided word for word, in their majority, by having the Systemic Functional Grammar as their theoretical basis, specifically by the processes of the Transitivity System postulated by Halliday, (1985); Halliday and Mathiessen, (2004); Eggins (2004); Cunha and Souza (2011). The work makes the field of Cultural Studies emerge towards the dialogue and the presentation of the fragmented identities of the teachers in the context of late modernity (GIDDENS, 2002; HALL, 2011). The thesis promoted a reflection over the teacher s condition, who is immerse in this context of knowledge construction of the present Brazilian educational system, the standardized evaluations, the indexes of development, the targets and the rankings. The considerations and outcomes of such a research dealt with the teachers emerging social practices and the need of planned initial and continuing teacher education towards the new moment which is foreseeable

Análise textual dos discursos: responsabilidade enunciativa no texto jurídico

This investigation aims at describing, analyzing and interpreting the Commitment in Initial Petitions, which is a genre circumscribed in the judicial domain. For this purpose, we have chosen sections, facts as found and relevant law , sections of the petition, with the understanding that, in this way, respectively, the narration of events, which gives margin to the propositioning to the judicial action, and the exposition of the law that upholds the author s intention. We base our discussion on the field of Linguistics, more precisely, Textual Discourse Analysis (TDA), whose theoretical basis is derived from Textual Linguistics (TL) and Enunciative Linguistics. We foreground, particularly, the way in which the author of texts, objects of analysis, use discursive strategies that evidence ER. The relevance of this study, then, is in the formation of a critique of the judicial text, as it conceives of a dialogical approach to the point of view, raising not only questions about the way in which a linguistic instance conceives an object of discourse, but also considering questions of language inherent to technical writing and, in this aspect, contributing to the work of those operating in Law about the many ways ER is formed in the body of a petition. We selected two categories to analyze that, according to Adam (2011), characterize the degree of ER in the textual material of the propositional enunciations: the different types of representation of speech and the indications of profile of mediators. In this sense, with this task as an objective, we base our study regarding point of view on Rabatel (2003, 2009a, 2010) with relation to the enunciative approach, including the study of PDV in polyphonic and dialogical theoretical framework to study the ER from different types of speech representations that conceive forms of transmission of discourse and the role of the enunciating subject, mainly the responsibility and the prerogative by the propositional contents. In the same way, intending to study the indications of the mediator profiles, we observed the postulations of Guentchéva (1994, 1996), which develop the notion of mediative grammatical categories, of which permit the linguistic marking of distance and engagement of the enunciator with regard to the information expressed. The methodology we adopted was based on qualitative research, of an interpretive and introspective nature, in light of the fact that his study focuses on processes and strategies underlying language use. The corpus of the research is comprised of Initial Petitions, which gave rise to actions originating in the Civil Court of Currais Novos County RN. The data analysis shows that an object of discourse is always perspective oriented and presents the point of view of one or more enunciators. Consequently, the producer of a text, using the PDV of other enunciators, influences and establishes the argumentative orientation of the text. In the same way, it evidences the relevance of the use of mediated constructions in the judicial text, as they function as strategies attenuated to the responsibility of the producer of the text with what is said, and at the same time points to a discourse of authority through the entrance of the sources of law. Moreover, it reveals the documental and international importance of this practice, at the same time that it exposes the compositional and normative difficulties with regard to legal and linguistic aspects

Metafísica e moralidade na filosofia de Schopenhauer

This work posits a mutual implication between metaphysics and morality in the philosophy of Schopenhauer and seeks to clarify the many nuances that take place in this relation. Each chapter offers a perspective in which the relation between metaphysics and morality can be addressed. Thus, by exposing some important aspects of representation theory of Schopenhauer, we try, in the first chapter, explain the relationship between his idealism and his conception of morality; in the second chapter, the determinism present both in nature and in moral actions, determinism that establishes the relationship between morality and metaphysics through the very notion of a metaphysical nature; in the third chapter, relationship between metaphysics and morality that takes place through the notion of freedom as denial of the previous determinism, freedom possible to the genius, to the saint and to the ascetic. All of these perspectives, however, presuppose the distinction between phenomenon and thing-initself, figuring this distinction as crucial in building of this metaphysic that seeks to protect the moral significance of the world while denying the existence of God

Nos tempos do blackout: cena musical, práticas urbanas e a ressignificação da Rua Chile, Natal-RN

This study aims to analyze the process of resignification of Chile Street, in Natal, from the development of a music scene in the late 1990s. Chile Street, as part of the Historic Centre of Natal, had its images constructed from the discursive practices and everyday life of its regular visitors, leading to a series of symbolic and imaging transformations throughout the twentieth century. Initially transformed into glamorous space as a result of urban actions of the new republic of Albuquerque Maranhão, in the early twentieth century, Ribeira and Chile Street, specifically, came to be seen as bohemian area, during the war time"; followed by a marginal phase, it was eventually transformed into the main rocker area of Natal, with the development of a musical scene in the second half of the 1990s. This music scene, its practices, economic interests, cultural events and identity ties created among their practitioners made Chile Street, "in the time of Blackout night club", an "alternative" space. As the historic centers, inserted in the logic of postmodern city marketing, both spaces are dynamic in their practices, as in their images, Chile Street also suffered changes in its meanings and symbols, around the year 2000 when the alternative-underground space became a pop space, where people from various parts of the city began attending its events and places, transforming it into a point of very heterogeneous sociability

Encontros entre dança, subjetivação e saúde mental

Taking from starting point the contact with the experience of a dancing body language group at Centro de Atenção Psicossocial (CAPS) II in Fortaleza-CE, aiming to investigate the relationship between what we denominate dancing-dispositive and the process of de-institutionalization of insanity. Based in the philosophy of difference and in the cartographic perspective, we used the concept of dispositive in order to make visible the lines that compose it and the way they tangle in the production of different ways of subjectivation through another form of expression using the body. We followed two fortnight groups of body language recording the conversations that took place in the beginning and in the end of the activities. We also recorded our informal talks with the workshopper, with the psychiatrist responsible for the course of formation of artists of CAPS and the choreographer who was part of the artistic formation of the workshopper aiming to elucidate the body, dance and art conceptions which guided such work. Finally, we interviewed some technicians and we participated of a meeting of the team aiming to understand how that activity was perceived. We observed that the use of certain conception of dance in the field of mental health is in consonance with the the Phychiatric Reform, since it provides another way of dealing with the body, different from that produced by the contention and by the discipline. Nevertheless, we understood that there is a risk that, in some moments, the group being more a place of normalization than one of experimenting other ways of relating with yourself and with the others. We also noted that the dancing-dispositive appears as an important analyzer of the connections established at CAPS, indicating a need of the service to be more opened to the production of new care and harboring strategies, breaking the mental health facility logic of incarceration of life which still persists in the quotidian of that institution

Estratégias de cuidado integral à saúde: os CAPS no processo de implementação do apoio matricial em Natal/RN

This study aims to analyzing the implementation of the Matrix Support proposal with professionals of Substitutive Services in Mental Health in the city of Natal/RN. The Matrix Support (MS) is an institutional arrangement which has been recently adopted by the Health Ministry, as an administrative strategy, for the construction of a wide care net in Mental Health, deviating the logic of indiscriminate follow-through changed by one of co-responsibility. In addition to this, its goal is to promote a major resolution as regards health assistance. Integral attention, as it is intended by the unique health system, may be reached by means of knowledge and practices interchange, establishing an interdisciplinary work logic, through an interconnected net of health services. For the accomplishment of this study, individual interviews of semi-structured character were used as instrument, with the coordinators and technical staff of the CAPs. The data collection was done in the following services: CAPS II ( East and West) and CAPS ad ( North and East), in the city of Natal/RN. The results point out that the CAPs to initiate of the discussion the process in the implementation of the MS aiming, to promote the reorganization and redefinition of the flow in the net, thus not acting in a fragmented way. Nevertheless, there is no effective articulation concerning the basic attention services, there is a major focus of the attention in mental health on the specialized services, little insertion in the territory and in the everyday life of the community

A psicologia e o programa de saúde da família :novas possibilidades, velhos dogmas?

The model of attention to health has been suffering alterations due to the difficulty faced to put into practice its universal, democratic and institutional layout. Since the movement of Sanitary Reform, which focused in the demands of a new health context and the process of work in the area of health, one seeks uninterruptedly, to find a way which leads to the execution of the principles of SUS. Despite having tried, the model of Sanitary Vigilance centered within the work of a multi-professional team has shown fragmentation and little adequacy to the necessity of health in the population. Whilst inserting himself in the field of health, the psychology professional has taken with him his clinic way of attending to individuals being one more in the team to act in a de-contextualised and little critical way. In virtue of this framework, the Ministry of Health invests in the Family Health Program as a new guide in the health system, restructuring the basic attention at a new logic of action. In this way, the municipality of Natal-RN implants, in the year 2002, the PSF in the Northern Sanitary District, a context in which professional teams are created where there is not an inclusion of a psychologist. Consequently, this professional is excluded of his work space in the previous Basic Unities of Health. This piece of work constitutes in the investigation of the implementation and instrumentalization of the Northern Sanitary District PSF of Natal-RN, having as its objective to analyze the implications of this execution for the structuring of the health network services and more specifically the alterations that this implementation could be making to the practice of the Psychology Professionals, emphasizing its advances, obstacles and limitations. To make this work feasible it was necessary to search for data and information from the implementation and execution of the PSF in the DSN, carrying interviews from a semi-structured guide, with 21 institutional actors (members of the team, coordinators and directors of the unities and psychologists)

O aborto provocado como uma possibilidade na existência da mulher: reflexões fenomenológico-existenciais

Abortion is a very controversial and stigmatized subject, target of many criticism and discussions, mainly regarding to the legal, bioethical and religious aspects involved. In Brazil, abortion is considered a serious public health problem, being the major cause of maternal death due to its criminalization. The woman who causes an abortion is not up looked by society, since motherhood, culturally and historically, was imposed as a destination. Our main goal is to understand, from the existential-phenomenological perspective, the unique experience of the woman who induced the abortion This study is an offshoot of a larger study from USP in partnership with UFRN. Our participants were women who checked in on a maternity hospital in Natal with a miscarriage diagnosis and, among them, those who reported having induced abortion. Altogether, five women were interviewed. The used method was a phenomenological hermeneutics. The research revealed that the experience of abortion is a possibility that permeates women s life, being understood as a choice. This choice pervaded by much suffering, once it goes against everything that women are culturally taught and meant to be. The feeling more surfacing in this experiment, confirming the literature review, was blame. Abortion was also shown as an experience of helplessness and loneliness, due to lack of support from family and the partner. It was also revealed that abortion was made, mainly, by the desire of going along with future projects, including the prosecute of motherhood in the therms of what they consider ideal to a son s arrival, meaning, a family formation grounded on a stable relationship. Regarding the care provided by health professionals to these women, there is the need of restructuring the operating logic of SUS, so that women have the right to health in a integrate manner. This experience also made women reconsider the meanings they had towards abortion, and their life projects

O Serviço Social nas operadoras de planos privados de assistência à saúde: demandas, atribuições e respostas profissionais

The present study deals with the exercise of professional social workers in private health care plans registered with the Regional Council of Medicine/RN, in the city of Natal/RN, with regards to the demands/tasks, work conditions, and the professional response, given the climate of restructuring the capital. The set of socio-historical transformations, as a results of the dynamic capitalist, is a process of new configurations in relation to state and society that interfere directly in relation to working conditions, social rights historically won by workers. In this context, the operator of health plans arises as a possibilities to provide services in health, through the logic of the market, in which the subjects of law, become consumers contributing to the displacement of the responsibilities of the State. Obligating workers to lessen the burden with the reproduction of their workforce. This involves changing societal context for social service, since it is one of the professions that are active in terms of the immediate social issue, and come as part of the collective worker. From qualitative research based on a theoretical and methodological perspective and critical dialectics, it was possible to unveil some features and trends of the exercise of(a) social operators in private health care plans. The survey results indicated that : a) the demands and duties for certain social service, are associated with the redevelopment of the capital, whose requirements and responsibilities professionals have with their needs, particularly the guarantee of profit, services rendered; b) in the conditions of work there is a trend of insecurity uncertainty and dismantling of professionals; c) the answers professionals suffer the limits and contradictions present in the daily training, mainly depending one the characteristics of management and operation of the operators, which has professional relative autonomy
