Tangibilidade, classe de ativos e estrutura de capital das empresas listadas na BM&FBOVESPA

This study aims to investigate the influence of the asset class and the breakdown of tangibility as determinant factors of the capital structure of companies listed on the BM & FBOVESPA in the period of 2008-2012. Two current assets classes were composed and once they were grouped by liquidity, they were also analyzed by the financial institutions for credit granting: current resources (Cash, Bank and Financial Applications) and operations with duplicates (Stocks and Receivables). The breakdown of the tangible assets was made based on its main components provided as warrantees for loans like Machinery & Equipment and Land & Buildings. For an analysis extension, three metrics for leverage (accounting, financial and market) were applied and the sample was divided into economic sectors, adopted by BM&FBOVESPA. The data model in dynamic panel estimated by a systemic GMM of two levels was used in this study due its strength to problems of endogenous relationship as well as the omitted variables bias. The found results suggest that current resources are determinants of the capital structure possibly because they re characterized as proxies for financial solvency, being its relationship with debt positive. The sectorial analysis confirmed the results for current resources. The tangibility of assets has inverse proportional relationship with the leverage. As it is disintegrated in its main components, the significant and negative influence of machinery & equipment was more marked in the Industrial Goods sector. This result shows that, on average, the most specific assets from operating activities of a company compete for a less use of third party resources. As complementary results, it was observed that the leverage has persistence, which is linked with the static trade-off theory. Specifically for financial leverage, it was observed that the persistence is relevant when it is controlled for the lagged current assets classes variables. The proxy variable for growth opportunities, measured by the Market -to -Book, has the sign of its contradictory coefficient. The company size has a positive relationship with debt, in favor of static trade-off theory. Profitability is the most consistent variable in all the performed estimations, showing strong negative and significant relationship with leverage, as the pecking order theory predicts

Avaliação da expressão das moléculas HLA de classe I não clássicas HLA-G E HLA-E em espécimes gástricas de pacientes acometidos com a bactéria Helicobacter Pylori

The expression of human leukocyte antigen G (HLA-G) and human leukocyte antigen E (HLA-E) in physiological and pathological processes remains unknown, it is believed that these molecules play a fundamental role in the establishment and maintenance of immune tolerance by inhibiting the functions of immunocompetent cells. In literature we found no published study involving the bacterium Helicobacter pylori (H. pylori) with expression of HLA-G and HLA-E. The objective this study is investigated the expression of this protein in gastric biopsies of patients with the bacterium H. pylori. Sixty-four biopsies of the patients with diagnosis of infection by H. pylori were evaluated to expression of HLA-G and HLA-E. The samples were stratified according to the presence of carcinoma or peptic ulcers. Patients without H. pylori were used to control. To investigate the expression of this protein were used immunohistochemistry technique with monoclonal antibody anti-HLA-G and anti-HLA-E. Other criteria such as analysis of the inflammatory infiltrate (hematoxylin-eosin) and identification of H. pylori (Giemsa) were analyzed. We detected HLA-G and HLA-E molecules in the most samples containing ulcer and gastric carcinoma. In negative control group was not detected the presence of HLA-G and HLA-E. The presence of H. pylori seems modulate the expression of HLA-G and HLA-E, favoring the evolution of infection, giving different degrees of gastric lesion in epithelium of these patients

O aluno surdo em classe regular: concepções e práticas dos professores

Le texte se rapporte à une recherche sur les conceptions d enseignants concernant l inclusion scolaire d élèves sourds , et leurs ralations avec les pratiques qu ils développent dans les classe régulières. Elle a été conduite dans une école publique régulière appartenant à la commune de Assu RN, et dont le choix méthodologique a été une approche qualitative, du genre ethnographyque. La construction des données devient d un processus d observation, de l application d entretiens demi-structurés et de l analyse de documents, ayant pour sujets quatre enseignants des années initiales de l enseignement fondamental. L apport théorique de base a été la théorie socio-culturelle proposée par Vygotsky (2003 ; 2005), censée traduire la compréhension de l homme dans sa dimension historique et culturelle, et mettre en évidence l interaction sociale en tant que condition pour le développement des individus. Les données font connaître que les enseignants sujets de la recherche sont favorables à l inclusion scolaire des élèves sourds dans les classes régulières, néanmoins soulignent le besoin d un changement à l école pour que l inclusion devienne une réalité. Les enseignants sont d avis que l apprentissage des élèves sourds se fait d une façon qui met trop de temps, moyennant l utilisation de recours spécifiques, tels que l usage du langage des signes (Libras). Ils signalent les difficultés qu ils doivent faire face quand il s agit de travailler pédagogiquement avec ces élèves dans le quotidien, telles que : manque d un travail collectif à l école ; besoin d une formation spécialisée ; démonstration de sentiments de peur, ou préjugés de la part de quelques uns du personnel de l école , tout celà interférant directement dans leurs attitudes et leurs actions faces aux élèves ; manque d appui des instances administratives de l école ; absence de politiques consistentes pour guider l éducation sous un regard inclusif. Quant aux pratiques pédagogiques développées à l école, la recherche laisse voir que, par rapport à la présence des élèves sourds, très peu d adaptations y ont été introduites, d où se dégage que la planification des actions éducatives à l école se tourne, prioritairement, vers les élèves qui écoutent, c est-à-dire, vers un groupe apparemment homogène. On a constaté, en plus, qu il n existe pas à l école aucun professionnel habilité pour l établissement d un processus de communication avec les élèves sourds. Malgré ces difficultés, les enseignants avouent, quand même, que travailler avec ces élèves rapporte toujours des bénéfices, tels que la collaboration et le respect mutuels chez les élèves, l acquisition de nouveaux savoirs et l amélioration de la pratique pédagogique des enseignants

Narrativas infantis: o que nos contam as crianças de suas experiências no hospital e na classe hospitalar

This dissertation focuses on the narratives of children hospitalized with chronic diseases. The overall goal is to deduce, from the look of the child health care, hospital class contributions to the process of school inclusion. The research is part of the qualitative ethnographical approach and is based on the principles and research methods (auto)biographical in education and schooling in hospital. Participated in the investigation 05(five) children, aged between 06 (six) and 12 (twelve) years of age, treated at the Center for Children s Onco-Hematology, Varela Santiago Children s Hospital in Natal-RN. The corpus used for the analysis comprises five (05) narrative interviews, 03 (three) drawings made by children as well as records in the researcher s field diary. The sources were collected during the months of August 2010 to February 2011. The analysis revealed that the inclusion of the hospital class, and ensure the right to education, contributes to the construction of strategies for coping with illness and hospitalization, as it promotes autonomy, comfort, playfulness and self-knowledge, the rand the world, easing the stress of hospitalization. The figure of the teacher took the class hospital in the voices of children, a reliever and minimizing the role of double exclusion that cause illness and hospitalization, showing the contributions to (re) construction of identity and subjectivity constitution strengthened. The children interviewed said that the hospital class leave the hospital more cheerful. The playfulness and learning experiences in the hospital are seen by children as actions that go beyond the physical treatment of the disease, since it provides them with acceptance and understanding of hospitalization and illness, to give them affective security and emotional. In conclusion, the narratives of children confirm that the service class hospital ensures continuity of schooling, but they reveal, namely, that this service provides them socialization among peers and with adults, strengthening the emotional, social and cognitive biopsychosocial perspective of attention

Apropriações, conflitos e negociações de gênero, classe e sorologia: etnografando situações e performances no mundo social do HIV/AIDS (Rio de Janeiro)

Considerando o caráter multifacetado e socialmente heterogêneo da epidemia do HIV/AIDS, gostaria de refletir sobre as formas pragmáticas de apropriação, negociação e conflito de gênero em termos das disposições possíveis de masculinidade e feminilidade ou, ainda, suas amplas combinações entre homens e mulheres de diferentes identidades sexuais e diversos status sorológicos. Os contextos a serem explorados e descritos são aqueles particulares ao mundo social da AIDS, incluindo tanto o cotidiano de uma ONG AIDS específica, bem como os que se apresentam em situações tanto públicas como privadas na cidade do Rio de Janeiro. Pretendo discutir como novas subjetividades podem se constituir a partir dos usos de categorias sexuais e sorológicas, valores morais e de expressões performativas de gênero.

O comportamento eleitoral da nova classe trabalhadora no Rio Grande do Norte 2014: ideologia, avaliação de governo e voto

This thesis investigates the voting behavior of the fractions of the new working class in Rio Grande do Norte, more specifically in the cities of Natal, Mossoró and Caicó, from the presidential election of 2014. This research examined the ideology, the evaluation of government and guidance the vote of a portion of the working classes of RN voters. In Brazil, from 2003, socio-economic change has occurred perceptibly, especially in a part of the working classes who ascended socially and switched to the "C economic class." Thus, there was this period, a significant expansion of this social stratum. The expansion of the "class C" in the past decade in Brazil raised the academic debate and in the media about the emergence of a "new middle class". Neri (2008) termed the "class C" of the "new middle class" and that will be the central part of their studies. But the debate on the "new middle class" can not be simplistic to the point of considering that social mobility, the main variable income, entered this segment of the population in the middle class, because it has different specificities of the popular classes. To understand this phenomenon, the income variable was outdated, adding the importance of ownership of the means of production, control of labor power and the symbolic values in the division of social classes resulting in three fractions of the new working class: the management positions, non-heads and small fighters. In this study, using as a complement to the sociological approach (ideologies and social classes) and the performance evaluation was identified that the new working class (heads) mainly reproduced the ideological and political positioning of the middle class, resulting in the rejection of PT governments (2003-2014) and it’s social, compensatory and redistributive policies. From what has been seen, the new working class (chiefs) approaches the ideological and political behavior of the middle class that will reflect in their electoral choices and class interests. The new working class (not heads and small fighters who voted in the situation) because of its classist and ideological interests approached the Workers' Party positively evaluating the Lula-Dilma governments (2003-2014) due to the implementation of compensatory policies, and redistributive programs government turned to the popular classes. In a counterpoint, the voters of the new working class (not heads and small fighters) who voted null, reproduced the discourse of mainstream media and the middle class about the rejection of compensatory policies, redistribution and government programs of Lula-Dilma governments, and consequently they disapproved of the government Dilma and her candidacy.
