Volatilidade dos retornos e governança: um estudo de eventos da crise do subprime

The financial crisis that occurred between the years 2007 and 2008, known as the subprime crisis, has highlighted the governance of companies in Brazil and worldwide. To monitor the financial risk, quantitative tools of risk management were created in the 1990s, after several financial disasters. The market turmoil has also led companies to invest in the development and use of information, which are applied as tools to support process control and decision making. Numerous empirical studies on informational efficiency of the market have been made inside and outside Brazil, revealing whether the prices reflect the information available instantly. The creation of different levels of corporate governance on BOVESPA, in 2000, made the firms had greater impairment in relation to its shareholders with greater transparency in their information. The purpose of this study is to analyze how the subprime financial crisis has affected, between January 2007 and December 2009, the volatility of stock returns in the BM&BOVESPA of companies with greater liquidity at different levels of corporate governance. From studies of time series and through the studies of events, econometric tests were performed by the EVIEWS, and through the results obtained it became evident that the adoption of good practices of corporate governance affect the volatility of returns of companies

Da crise do estado à democracia como alvo: Observações sobre o neoliberalismo a partir de Friedrich Hayek e Milton Friedman

The neoliberalism proclaims the crisis of the State in front of globalization , but, approaching two books taken as basic on this theoretical chain - The road to serfdom, of Friedrich Hayek, and Capitalism and Freedom, of Milton Friedman - to analyze this supposed dualism, the conclusion into which we arrive is another one. Remembering liberal tradition and quickly, later, analyzing critically the workmanships, can be perceived that others are the conflicts really gifts in the current capitalist reality - market versus State et capitalism versus democracy - and, from the understanding on the reading made and the theoretical trajectory of its authors, we may see as the neoliberalism locates itself in relation to these conflicts, which polar regions of these antagonisms privileges, what represents the State for itself, and what it intends as much more global philosophy than economic/politics thinking only

Investigações em torno do antropocentrismo e da atual crise ecológica

Many environmental ethics thinkers bear the existing ecological crisis is resultig from the fact that both, our thoughts and our actions would be antropocentric. It means that they (our thoughts and our actions) would have the human needs and wishes satisfaction as their only goals. However, a careful investigation about the relationship among humans could perhaps unveil that we are not antropocentric yet. The aim of this work is to enlighten this: whether we think and act in an antropocentric way as it seems to be largely accepted. It seems that we have found a satisfatory answer to the question

Hannah Arendt e a crise na educação como crise político-filosófica da modernidade

Este estudo busca esclarecer e discutir a reflexão de Hannah Arendt sobre a crise na educação no mundo contemporâneo enquanto crise político-filosófica da modernidade. Trata-se de explicitar de que forma o significado da educação está atrelado às condições de instituição, compartilhamento e conservação do mundo comum e humano. Com o intuito de reconstruir as análises da autora sobre os reflexos da crise político-filosófica da modernidade na esfera prépolítica da educação, esta pesquisa investiga de que modo o fim da tradição metafísica, o esfacelamento da autoridade, o obscurecimento da esfera pública e a moderna alienação do mundo promoveram uma profunda degradação das capacidades humanas de construir, conservar e compartilhar pela ação e pelo discurso um mundo que possa sobreviver e permanecer um lugar não mortal para seres que nascem e morrem. Palavras-chave: Hannah Arendt; Educação; Crise; Modernidade; Autoridade; Espaço Público.

O Entrelaçamento entre assistência social e trabalho informal: verdades e equívocos em tempos de crise do capital

The thesis presented here is of interest management to analyze the performance of the State, through the materialization of the professional courses, the process of integration of users CRAS-Pajuçara informal. Therefore, we assume that poverty and inequality reach a significant portion of the world population, in a context where the working class family is seen as an alternative to face the multiple expressions of social issues. Thus, before the changes of Productive Restructuring, marked by flexibility, outsourcing and casualization of labor relations in the world, the working class family must find ways to ensure their survival. In this direction, we discuss the advances, limitations and challenges posed to the Social Assistance Policy in contemporary, situating this context, the role of the state. Furthermore, we discussed the functionality of informality to the capitalist system, showing how capital appropriates of informal work, placing it in its logic, and thus makes the capital-labor ratio increasingly predatory, inhuman and unequal. The methodological procedures for the preparation of this study constitute a literature and documentary, beyond 10 semi-structured interviews directed to users of CRAS-Pajuçara, participants of training courses for the period 2010-2011. In light of the critical-dialectical rationality, and in a context where informal work has increasingly been co-opted as an alternative to huge unemployment in the same direction in which the welfare rises in tackling social inequality, the scope of this study, discusses and reveals the truths and misconceptions that surround this bourgeois discourse, in times of crisis of capital, the city of Natal, Brazil

A incorporação de preceitos ambientais no sistema de gestão de resíduos sólidos do município de João Câmara - RN Brasil

The reality points to the global environmental sustainability as the only viable option for addressing the crisis at hand. The move towards sustainability calls for the generation / evaluation systems in their direction, through the incorporation of environmental requirements and in line with the National Policy on Solid Waste. Therefore, the proposed research supports the importance of social and environmental vision, complementing the technical view, the system for management of solid waste from East London, which is a municipality that has a system whose inadequacies are configured in environmental risk and health. Therefore, by observing, applying the model of sustainability indicators and content analysis of interviews, this research proposes to investigate the principles of sustainability and social participation are presented and what is the perception of risk about the inadequacies in the system. The results confirmed the hypotheses of the study and draw a picture of worrying data, such as very unfavorable indicators of sustainability, lack of channels of participation, uncommitted investments with the management system, devaluation of the collector of waste and differing perceptions about the risk by making actors act in isolation. This worrying situation is eased by the appearance of a series of elements are configured as opportunities for the integration of environmental principles in the system. And despite the inability of managers to participate in the research system, yet it behaves as an opportunity to implement public policies in the area of solid waste such as: the preparation of the municipal waste, the institutionalization of selective collection and organization of cooperative with the support of companies present in the city and educational institutions as the Federal Institute. The research is an opportunity for the implementation of policies in the area of solid waste and will collaborate with the building instruments for the quality of life of residents, for the socioeconomic conditions of collectors and the move towards a sustainable society

Questão urbana e ambiental em tempos de crise do capital: configurações e particularidades no Brasil contemporâneo

Este trabalho tem por objetivo discutir os nexos entre crise do capital, questão urbana e ambiental, problematizando a inserção subordinada do Brasil no processo de mundialização com predomínio das finanças, as contradições que marcam estes processos e, em particular, suas repercussões nas cidades na contemporaneidade.
