Luta por reconhecimento e desigualdade social: uma análise da experiência dos catadores da Asmare em Belo Horizonte (MG)

Esta dissertação discute a dinâmica de luta dos catadores da Asmare em Belo Horizonte (MG)e seus possíveis desdobramentos em políticas públicas para esse grupo social. Parte-se da ideia de luta e conflito social, recorrendo-se às discussões de luta por reconhecimento de Axel Honneth, apontando os limites e possibilidades do uso dessa abordagem no contexto brasileiro em face da elevada desigualdade social. A investigação foi realizada a partir de um estudo de caso longitudinal, com recorte temporal de 1987 a 2010. Foram feitas entrevistas em profundidade, conversas espontâneas e observações. Como método de análise foi adotada a leitura de narrativas. A partir das múltiplas vozes presentes nas narrativas dos entrevistados, observa-se que a luta dos catadores da Asmare foi repleta de idas e vindas, contradições e conflitos. Nas narrativas dos catadores foram evidenciadas diferentes formas de desrespeitos e reconhecimento recusado, bem como expectativas morais de reconhecimento. Foram alcançadas reivindicações junto ao poder público local, como a construção de uma política de apoio ao trabalho desse grupo que, ao longo dos anos, foi passando por reconfigurações e mais recentemente por uma inflexão, que acirrou os conflitos entre poder público e Asmare.

O processo de autogestão do grupo de psicólogos da Secretaria Municipal de Educação

O presente trabalho tem por objetivo estabelecer uma análise da prática dos psicólogos na Secretaria Municipal de Educação do Rio de Janeiro, durante os anos de 1983, 1984 e início de 1985. Descreve o processo vivido pelos psicólogos, em busca de reconhecimento profissional e de autonomia técnico-administrativa, na construção de uma identidade profissional, do papel e função do psicólogo na estrutura oficial de ensino da SME do Rio de Janeiro. Nesse processo, identificamos a relação de trabalho do psicólogo com o pedagogo num campo eminentemente pedagógico, as contradições existentes no grupo de psicólogo ao longo de seu processo de desenvolvimento profissional e a ameaça vivida pelo instituído a partir da organização de um grupo instituinte, que procura contribuir para a transformação de instituição onde atua.

Antecedentes à transição de carreira na área de tecnologia da informação

A falta de profissionais com perfil e qualificação em tecnologia da informação (TI) é uma dificuldade enfrentada pelas empresas em geral, as quais investem crescentemente em TI e cada vez mais são dependentes e influenciadas pela tecnologia. Além dessa questão, observa-se que apesar das boas oportunidades de emprego no setor, a evasão nos cursos superiores de TI tem atingido patamares altíssimos, agravando ainda mais o problema da escassez por talentos qualificados. Assim, esta pesquisa estuda a migração dos profissionais de TI para outras áreas, fenômeno denominado turnaway, problema que agrava ainda mais a situação em que se encontra o setor de tecnologia da informação no mercado brasileiro, requerendo uma solução a curto prazo e merecendo uma exploração e discussão em profundidade. O objetivo principal deste estudo é, portanto, identificar as principais razões que explicam a intenção dos profissionais de TI em abandonar a área. Assim, foi realizada uma pesquisa explanatória, por meio de pesquisa bibliográfica e investigação empírica, aplicando-se questionários disponibilizados eletronicamente a profissionais de TI de diferentes empresas e áreas de atuação. A amostra utilizada teve 323 respondentes e os dados obtidos foram analisados estatisticamente via modelagem de equações estruturais. Como resultado, esta pesquisa mostrou que a transição de carreira na área de tecnologia da informação está intimamente associada ao dinamismo natural da área, às condições de trabalho que geram fadiga física e mental, e às restrições de crescimento profissional na área técnica, levando os profissionais de TI a uma insatisfação com a área que os faz buscar capacitação gerencial e novas experiências de trabalho, de modo a ampliar sua rede de relacionamento interpessoal e abrir oportunidades em diferentes campos de trabalho, possibilitando, desta forma, a migração dos mesmos para outras áreas que oferecem melhores condições de trabalho, maior reconhecimento e possibilidade de crescimento profissional.

Desafios na avaliação de incorporadoras imobiliárias brasileiras de capital aberto

Primeiramente, além de fazer análise resumida do setor de incorporação imobiliária brasileiro, a dissertação argumenta porque métodos tradicionais de valuation são inapropriados para avaliar incorporadoras e construtoras brasileiras. Entre os pontos levantados estão: as regras contábeis do setor, o modelo de negócios de incorporação no Brasil, a natureza cíclica do negócio, o descasamento entre geração de caixa e reconhecimento de receitas, e o tipo de informação disponibilizada pelas empresas listadas na bolsa de valores. Em seguida, o estudo sugere um método mais adequado, partindo de um conceito de Soma das Partes, onde calcula-se separadamente o valor líquido dos ativos, do banco de terrenos e dos projetos futuros. Metodologias semelhantes começaram a ser utilizadas por alguns bancos de investimento em anos recentes, porém nunca foram discutidas de forma mais acadêmica. Argumenta-se que o método proposto parece adequado, pois não só produz resultados compatíveis com a intuição econômica, como também permite que o usuário faça análises de sensibilidade de forma simples e direta. Finalmente, ao comparar a evolução no período entre 2008 e 2014 dos preços das ações de algumas incorporadoras imobiliárias listadas, discute-se quais ações estariam subavaliadas e quais estariam superavaliadas.

A cláusula de melhores esforços (best efforts) na prática jurídica brasileira: uma nova perspectiva

A utilização da cláusula de melhores esforços, ou best efforts, é prática comum do empresariado e advogados nacionais. Este trabalho realiza um levantamento a fim de demonstrar a alta incidência em acordos sofisticados entre acionistas de companhias abertas brasileiras. Tal inclusão tem fortes motivos econômicos, a justificar o reconhecimento e interpretação pelo aplicador do direito nacional. O padrão de conduta dessa obrigação de meio deve ser analisado por critérios distintos, por meio de elementos subjetivos e objetivos, bem como à luz do contexto social e usos e costumes relacionados, baseados em normas e princípios de direito privado amplamente aceitos. A escassa jurisprudência sobre o tema bem como a já consolidada jurisprudência norte-americana contribuem para o melhor entendimento sobre a natureza jurídica e o modelo de interpretação de conduta a ser aplicado, diferenciando a obrigação de melhores esforços dos deveres decorrentes da boa-fé objetiva. Entre as conclusões, pode-se mencionar que a cláusula de melhores esforços não deve ser igualada aos deveres de boa-fé ou a um mero dever moral. Seu reconhecimento legal como padrão de conduta distinto, apurado conforme cada caso, deve ser amparado pelo ordenamento jurídico nacional

Coevolução e as práticas isomórficas de gestão: um estudo sobre os processos de mudanças institucionais no Instituto Federal de Educação, Ciência e Tecnologia do RN

The Federal Institution for Education, Science and Technology, in its historical path, has been living different changes. The transformations occurred along the way have been determined by coercive forces from the institutional environment, which has became more and more broad and complex throughout the time, obtaining diverse characteristics and new elements such as non institutional factors1 which started to contribute with the other changes. In this context, this work aims to study the isomorphic practices of the managers in the institutional changes process of the IFRN in 1998 and 2008, as of a theoretical coevolutionary perspective (CHILD; RODRIGUES; LEWIN; CARROL; VOLBERDA, 2003). This theory brings a new point of view for the organization analysis to the organizational studies, since it offers a non deterministic and non linear lection of the evolution process, which means, a coevolution. Thus, the organizations and their institutional and non institutional environment auto evolve, auto organize and auto reproduce. Therefore, the institutional and non institutional factors of the macro environment keep a continuous interdependence relationship with the organizations. For the means of this study, it is important to understand that is impossible to comprehend the object, the isomorphic practices, without considering that the previous institutional changes and its evolutions, its continuations and discontinuations, important in the coevolution process. As such, to call upon the institutional historical track is a fundamental aspect to materialize this study, for the recursive movement is indeed present in the coevolution. Another important point to make this research effective is that it is not possible to abdicate from the hologramatic view2 of this study, which considers the object, the isomorphic practices, part of the whole and this whole is also in the parts, therefore it is impossible to comprehend the object of study outside the context where it belongs. With this, as of the objective previously proposed, it is necessary to describe the characteristics of coevolution of the institutional changes related in 1998 and 2008; analyze the dynamic of the isomorphic mechanisms in its respective institutional change process; and describe the lessons learned which the isomorphic practices left to the IFRN, regarding its benefits and difficulties. All these transformations happened through coercive forces3 of the institutional environment. As of the Nineties, these forces became stronger, the environment became broader and more complex, with the emergency of new environmental factors. This study proposed to study the managing process and its practices, related to the micro environment, although it is required to articulate these actions, the demands and requirements from the macro environment. To make this research effective, semi structured interviews have been conducted with the managers who participated in both institutional change processes. In the results analysis, it has been possible to verify the particularity of each change, the one from 1998 with a strong normative action of the managers against coercive forces from the government for the search of recognition and the institutional legitimation and the one in 2008, which has been characterized by the normative action by managers in agreement with the coercive forces from the government, in favor of the government policy for the technological professional education. However, the results analysis it is possible to notice the evidence of a belonging feeling from the interviewed managers

Modulação da expressão da proteína XPA em resposta ao tratamento com azul de metileno fotossensibilizado

Reactive oxygen species (ROS) are produced by aerobic metabolism and react with biomolecules, such as lipids, proteins and DNA. In high concentration, they lead to oxidative stress. Among ROS, singlet oxygen (1O2) is one of the main ROS involved in oxidative stress and is one of the most reactive forms of molecular oxygen. The exposure of some dyes, such as methylene blue (MB) to light (MB+VL), is able to generate 1O2 and it is the principle involved in photodynamic therapy (PDT). 1O2 e other ROS have caused toxic and carcinogenic effects and have been associated with ageing, neurodegenerative diseases and cancer. Oxidative DNA damage is mainly repaired by base excision repair (BER) pathway. However, recent studies have observed the involvement of nucleotide excision repair (NER) factors in the repair of this type of injury. One of these factors is the Xeroderma Pigmentosum Complementation Group A (XPA) protein, which acts with other proteins in DNA damage recognition and in the recruitment of other repair factors. Moreover, oxidative agents such as 1O2 can induce gene expression. In this context, this study aimed at evaluating the response of XPA-deficient cells after treatment with photosensitized MB. For this purpose, we analyzed the cell viability and occurrence of oxidative DNA damage in cells lines proficient and deficient in XPA after treatment with MB+VL, and evaluated the expression of this enzyme in proficient and complemented cells. Our results indicate an increased resistance to treatment of complemented cells and a higher level of oxidative damage in the deficient cell lines. Furthermore, the treatment was able to modulate the XPA expression up to 24 hours later. These results indicate a direct evidence for the involvement of NER enzymes in the repair of oxidative damage. Besides, a better understanding of the effects of PDT on the induction of gene expression could be provided

O sindicato como espaço de construção da profissão docente

This work examines the connection Syndicate/teachers profession trying to unveil the important role taken over by the Syndical movement in the process of professionalization of the militant teachers. For that, it describes and analyses the historical course of three Syndicates representatives of the teachers category Associação dos Professores Licenciados da Bahia APLB; Sindicato dos Trabalhadores em Educação de Pernambuco SINTEPE; Sindicato dos Servidores Municipais de Petrolina SINDSEMP acting in the micro-region of the San Francisco Valley, especially, in the municipalities of Juazeiro Bahia , and of Petrolina Pernambuco. It concentrates its interests on the contribution of the Syndicates for the professional development of these teachers in this region analysing the aspects related to emerging conflicts into the Syndical organization, to the attitude of these entities before the educational reality to their reinvindicative struggles to the formative dimension of the group actions. This study tries to answer the following questions: How has this syndical movement of teachers of state school of S. Francisco Valley been characterized? How do their actions reflect in the formation and professionalization of the teachers? Do teachers recognize the syndicate as a constructive space for the teaching profession? The methodological trajectory was directed through a qualitative approach of an etnomethodological character, using instruments for the understanding of this reality, The treatment of the data was based on the interpretative analysis of the speeches present in documents and through answers of the interviwees, having as a reference in this analysis the theoretical studies about syndicalism and the teacher professionalization. For a conceptual construction of this work it was studied these two categories from their genesis, from the social historical evolution of their concepts and the up to date discussions that give explanations about the teachers syndical movement and about the process of teachers professionalization. As thesis of this study it was defended the idea of that the teachers syndicates have contributed expressively in the process of the construction of the teacher profession of the militant teachers of this in the micro-region of the S. Francisco Valley. Once the teachers participate actively in this movement promoted by the syndical entities, the teachers develop the critical sense of the educational realty; improve their formation and reinvindicate from the State this condition as a Right; fight for better conditions in the work; reinvindicate the salary valuation and, try to construct an image of teacher basing on a professional model. The contribution of the Syndicate in the process of teachers profissionalization, is more evident in its external dimension that chacterizes the profissionalism, on the related aspects: to the forms of participation in the definition and the management of the educational politics; to the political struggles for the achievements of the professional status, to the recognition and of his eventual valuation. The syndical actions have repercussions with less intensity in the inside dimension that defines the profissionality, in the related aspects: to the administratation of the pedagogical processes in schools and in the classroom; to the acquisition of branches of knowledges; to the epistemological criticism of the acquirements mobilized in the teaching; the curricular question to the mediation that make possible the learning at school and in the classroom

A Internet como tecnointeração da aprendizagem: valorização da cultura e identidade juvenil

The present study investigates Internet as technological interaction in the school environment as a resource of the teaching-learning process. It aims to discuss the lack of synchronicity between proposals of educational access for Internet use and types of access and interaction applied by youngsters. For the development of this research, I resorted to a qualitative, descriptive and explanatory research focused on a group whose subjects are youngsters from eleven to fifteen years of age in a catholic school which belongs to a group of private teaching schools in Natal city, Rio Grande do Norte state. As methodological option it focus on a group and the observation of its participation, discourse analysis and ethnography, considering facts and data of the pedagogical practice concerning the focused theme, besides the attempt to know the youngsters everyday at school and the relationship between them and juvenile cultures. It recognizes the existence of two moments of the focused group: the first related to internet use like technological interaction; the second concerns to the way Internet is problematic as technological interaction in classroom learning. While contacting with youngsters, the study discusses the concepts of Media Environments, Culture, Identity, Network, Consumption and Citizenship. It recognizes that it is relevant for the school to consider Internet a pedagogical tool, directed not just at research, but mostly as learning environment and as learning construction in a collaborative way. It points out the need of approach between school and media environment, reevaluating the pedagogical practice, offering a new evaluation proposal (self-evaluation). It suggests a renewal in the teacher's pedagogical practice in the classroom and using Internet, valuing the connection between technological interaction and communication as motivation elements of student s learning construction and their effective participation in decisions involving citizenship. It gives priority to educational work directed at the establishment of dialogic relationship between codes, learning and contents, leading to the new findings domain in the media environment, enabling the development of abilities and performances directed at the recognition and consumption of information from a critical reading of the media

Beirando a vida, driblando os problemas: estratégias de bem viver

The purpose of this study is to analyze the strategies used by families living in at-risk-and-vulnerable situations registered with the Estratégia Saúde da Família (ESF) ( Family Health Strategy ) as they face their daily problems. This is an investigation of a qualitative nature, using interview as the main tool for an empirical approach. Ten women from the Panatis location in northern Natal, Rio Grande do Norte, whose families live in precarious social-economical situations were interviewed. The interviews occurred between the months of April and June, 2007. The reports revealed that a mixture of improvisations and creativity was used as strategies for overcoming the privations and necessities of daily life. We also reached the conclusion that these families sought solutions for their problems through religiosity and a gift reciprocity system as resources for obtaining personal recognition and support in adversity. The results, in addition, point to ESF as one of the strategies used by these families in the search for attention and care. From this perspective, ESF has proven to be a place for listening and the construction of ties that are consolidated through home visits, organized groups, in parties and outings that are promoted in the community, reestablishing contact and support among people and signaling a way out of abandonment and isolation. Holders of knowledge constructed through life experiences, the participants of the study led us to induce and infer the need to amplify space that will allow them to express meanings, values and experiences, and consider that becoming ill is a process that incorporates dimensions of life that go beyond the physical. As health professionals, we need to be aware of the multiple and creative abilities used in the daily lives of these families, so that we can, along with them, reinvent a new way of dealing with health

Proposta de algoritmo para detecção de vazamentos em oleodutos utilizando análise freqüencial de sinais de pressão

Pipeline leak detection is a matter of great interest for companies who transport petroleum and its derivatives, in face of rising exigencies of environmental policies in industrialized and industrializing countries. However, existing technologies are not yet fully consolidated and many studies have been accomplished in order to achieve better levels of sensitivity and reliability for pipeline leak detection in a wide range of flowing conditions. In this sense, this study presents the results obtained from frequency spectrum analysis of pressure signals from pipelines in several flowing conditions like normal flowing, leakages, pump switching, etc. The results show that is possible to distinguish between the frequency spectra of those different flowing conditions, allowing recognition and announce of liquid pipeline leakages from pressure monitoring. Based upon these results, a pipeline leak detection algorithm employing frequency analysis of pressure signals is proposed, along with a methodology for its tuning and calibration. The proposed algorithm and its tuning methodology are evaluated with data obtained from real leakages accomplished in pipelines transferring crude oil and water, in order to evaluate its sensitivity, reliability and applicability to different flowing conditions

O discurso humorístico nas charges da Tribuna do Norte

In this dissertation, we analyze the constitution and functioning of the humorous discourse in discursive genre cartoon from the recognition and analysis of the techniques of humor used to get the desired effects of meaning. We used the theoretical and methodological assumptions of French Discourse Analysis henceforth (AD) for the research. Specifically on the techniques of humor, we rely on authors like Possenti (1998) and Propp (1992) to see how these procedures are present in the cartoons and make the discourse of humor. To achieve this goal, ten (10) cartoons were analyzed dealing with episodes relating to the management of the mayor Micarla de Souza in the city of Natal, RN. These cartoons were published in the newspaper Tribuna do Norte during the year 2012. The research falls within the field of study of Applied Linguistics and is qualitative, interpretive nature. In the first part, we did a rescue of the foundations of discourse analysis, discussing the concept of interdiscourse, then we carry on about the notion of gender discourse from the perspective of AD, and the genre itself cartoon as we work with the cartoon as a discourse genre, and finally, we deal with this humor discourse in cartoons. We then developed some analyzes to illustrate the postulate that all text is founded upon certain conditions of enunciation; that the relationship between the cartoons and interdiscourse is a constitutive relationship that brings out certain cartoons/ discourses and not others, and especially what humor techniques are used strategically by the cartoonist, whose discursive decisions cause certain effects of meaning. The results of this paper find that discursive relations are relations of subjects and meanings, that the discourse of cartoon is built from other sayings and discourses, and that certain textual and discursive procedures/techniques, as parody, irony, lowering the other, the ambiguity and displacement are mobilized in the text to generate the possible effect of the comic, thus building the humor discourse of the cartoons analyzed
