Da proteção à precarização um estudo do fenômeno jurídico trabalhista no contexto das transformações do capitalismo

This research aims to investigate the effectiveness of the legal labor phenomenon in contemporary capitalism as rectifier element of the contradictions between capital and labor. From the analysis of legislative developments - state and business - and court decisions related to the category of freight transport is expected to determine the protectionist stiffness proclaimed by the institutional structure of labor in Brazil, considered by the hegemonic discourse as political-economic factor that prevents growth. It is intended to unravel the relationships between political and civil society, studying the internal contradictions and ideological influence among these spaces, with theoretical support in Marx and Gramsci. The function of this research is to test the premise that the protectionist discourse is a rational action of capitalism and the organic intellectuals of political society in order to achieve hegemony and hide the real contradictions between capital and labor, in addition to also assist in the discussion on deregulation and easing in Brazil. The analysis points to the confirmation of our premise, since the evolution of the legal phenomenon in the transport sector was charging toward the neoliberal project

Competitividade dos produtores rurais de cana-de-açúcar da região agreste do Rio Grande do Norte

Deregulation of the sugar-alcohol sector in the 90s meant that agribusiness firms begin a process of reorganization of their production structures to enhance their abilities to become competitive in the new scenario. This study aims to examine the Production Chain of Sugar cane in Agreste region of Rio Grande do Norte, with studies to contribute to the competitiveness of farmers giving grants for planning and implementing policies, programs and projects, public and / or private. The method used in the study was researching the literature on the history of sugar cane in Brazil, agribusiness management, production chains and competitiveness, in field research used a questionnaire to collect information from farmers. It is concluded that the rural producers of cane sugar in newborns are not competitive and therefore it is necessary policies and / or for private gain in competitiveness of producers and consequently the production chain. It is hoped that the study serves as a subsidy for those policies proposição

As relações de gênero no trabalho: uma análise da inserção das mulheres e homens na rede de fast food

The purpose of this study was investigate the sexual division of the work in a chain of fast food, in Natal, RN. These aspects were analyzed with the ways of organization of the work, being made a case study. The main objective of this survey was to analyze the influence of gender relations in the insertion of men and women in the job market and to analyze the question of feminine submission in the professional world. These questions were analyzed considering the current period of the worldwide capitalism, from the characteristics of productive process and the growth of the service sectors. The research was made with a group of workers on the production sectors; attendance, management and human resources at restfood store, where six clerks were interviewed. Through our research, it is possible to perceive the permanence of the sexual division at the job in the interior of the productive processes at Restfood, that puts the woman in a subordinate position in relation to the man. This result can be confirmed if we considerate that the women, on this chain of food, occupy in first place the function of waitress and on this, trere s no functional progression, while her workmates (the men) for occupying other functions can progress inside the company. It was also evidenced that in a context of globalization of the capital, deregulation and disrespect of labor laws, the capital acts without any respect to workers. That was what we observed at the interviewer speech; the scarcity of the conditions of work and the constant disrespect of the labor laws. This way, we could evidence that the scarcity of work conditions hit men and women, but it has a crueler face with the women, and this one reproduces itself, day by day in the process of social reproduction, through family life, insertion in the world of the work, information and received social education. So, the capital explores all of them, but the gender relations create to the capital, the possibility of a different degree of exploration, becoming this way, the women main victims herself

Associação da imunoexpressão das proteínas XRCC1, TFIIH E XPF com características clinicopatológicas e sobrevida em carcinoma epidermoide de língua oral

DNA repair systems, genes and proteins are essential for genome integrity maintenance, avoiding serious diseases such as cancer. Deregulation in the expression of those proteins has been associated with both the risk of development and evolution of various human cancers, including oral squamous cell carcinoma. The purpose of this study was to analyze the immunoreactivity of the DNA repair proteins XRCC1, THIIF and XPF in oral tongue squamous cell carcinoma (OTSCC) and to investigate its association with clinical and histopathological parameters, outcome and 5-year survival rate. Seventy-four cases of OTSCC were analyzed semi-quantitatively through immunohistochemistry. We observed that DNA repair proteins were highly expressed in parenchymal cells; however, we only observed a significant association between XRCC1 high expression and better clinical staging (p=0,02). Cox regression showed that tumor size (p<0,01), lymph node involvement (p=0,04), tumor stage (p=0,02) and depth of invasion> 4mm (p=0,05) were prognostic factors. The results of this experiment suggest that XRCC1, TFIIH and XPF participate in the tumorigenic process, however, their immunoexpression may not be used as an independent prognostic indicator for OTSCC.
