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

Relações entre mecanismos de coordenação e controle com desempenho organizacional: um estudo nas instituições públicas de ensino médio de Natal

This research aimed at relating coordination and control forms to organizational performance. The multicase study was applied in two public high schools: Centro Federal de Educação Tecnológica do Rio Grande do Norte and Floriano Cavalcanti. In order to accomplish these objectives, it was developed a qualitative analysis and considered coordination and control forms of several authors. Also was considered Sander´s (1984) model of organizational performance. The mentioned model considers two criteria to analyze organizational performance: one instrumental (efficiency and efficacy) and other substantive (effectiveness e relevance). The research attempts to show the importance of balancing these criteria in a way that effectiveness and relevance becomes more important at schools. It was proven that the use of bureaucratic coordination forms has the power to influence the evaluation on the instrumental technique. At the same time, it was observed that the use of mechanisms based on the autonomy of the school is related to efficiency and efficacy. The object of this research can be considered successful

Mecanismos alternativos de solución de controversias en el contrato estatal la amigable composición

Con este documento se pretende adentrarse mucho más en el estudio de los mecanismos alternativos de solución de controversias que puedan surgir dentro del desarrollo del contrato estatal y en especial el mecanismo denominado como la Amigable Composición de muy poca utilización entre las partes en conflicto pese a tener muchas ventajas en lo que tiene que ver con el procedimiento establecido para llevarla a cabo, efectos legales luego de su realización y la posibilidad de intervención de un tercero imparcial. Se entrara a manejar el tema desde las definiciones de cada uno de los mecanismos alternativos de solución de controversias consagrado para dirimir los conflictos que puedan surgir con ocasión de la celebración de un contrato estatal, hasta llegar a la comparación de cada uno de estos métodos con la Amigable Composición, estableciendo similitudes y diferencias para que el lector tenga los criterios suficientes para emitir una opinión en lo que tiene que ver con la mayor idoneidad de uno u otro mecanismo alternativo de solución de controversias.

A influência política na gestão das empresas estatais à luz do direito fundamental à boa administração e da governança corporativa e pública

This study is dedicated to explain the extent to which political influence in the management of state-owned enterprises can be considered legitimate in the light of the fundamental right to good governance and corporate and public governance, for which was undertaken bibliographical and documentary research guided by the deductive method of work, in which were investigated and presented concepts and issues relating to the State, Government, politics, Public Administration, constitutional principles of Public Administration, the fundamental right to good administration, corporate and public governance and state enterprises. Based on the assumptions found in the works and consulted laws it was possible to conclude that the political influence in state-owned enterprises management can be considered legitimate in the light of the fundamental right to good governance if it promotes the public interest and the public purposes achievement, effectively, efficiently and if it preserves the citizens' rights and the principles and rules that make up the legal framework for public administration; and can be considered legitimate in the light of corporate and public governance to the extent that, in a transparent manner and according to the relevant rules, it seeks not the private benefit of politicians, but to promote the public interest or, in other words, the increase of public value produced by them, while protecting and guaranteeing the rights of its stakeholders and shareholders.

Utilidad de los diagramas causales para conceptualizar mecanismos en epidemiología laboral

Pese a que un objetivo de la epidemiología es la identificación de relaciones de causalidad entre un factor de riesgo y un problema de salud, la metodología de investigación de esta disciplina sacrifica a menudo la validez interna a favor de la capacidad de detección de asociación. Existen métodos gráficos y estadísticos que pueden ayudar a desentrañar los posibles mecanismos causales y así conocer algo mejor la llamada "caja negra". En esta nota se presentan los diagramas causales, una de las herramientas más útiles para plantear, antes del análisis, si una posible asociación es causal o simplemente debida a un sesgo. Para mostrar su utilidad, se proponen varias situaciones en el ámbito de salud laboral, mostrando cómo puede surgir asociación en rutas no causales a consecuencia de un sesgo. En conclusión, se recomienda el uso de los diagramas causales como parte de la praxis habitual en la investigación epidemiológica.

Transparência das informações públicas nos portais das instituições federais de educação profissional da região sul do Brasil

Considering the need of communication between public management and society and its citizens, in a way which is more effective and transparent, the aim of this research was to analyze the transparency of public information presented by the managers of the portals of southern Brazil’s Federal Institutes. It is a qualitative and quantitative research, applied as its purpose, and exploratory as its aim. In order to explain the issue from the theoretical frameworks published, it will be used as a procedure the bibliographic research and the further study field research in the six southern Brazil’s Federal Institutes. Therefore, the theoretical framework approaches aspects about public transparency, concepts of information and communication in the public sector, and it presents measurement indexes of public transparency. The data collection with the Institutes sought to measure – in the portals – the level of transparency of the information presented by the managers, applying a search tool which provided the transparency index of eleven categories of the researched items, besides verifying the presence of the required items by Access to Information Law. In the sequence, it sought to verify the Institutes managers’ perception of the aspects which composes the proposed theme, for the purpose of observing how the process of communication between public agencies and the citizen is happening. The main results obtained emphasize, in a general way, a low level of public information propagation, with a lower average of propagation to the information about social, environmental and economic responsibility, and a greater average to the information related to the institution’s general data – from its management structure to its ordinance. It was also observed that no institution which was researched fully comply with the demands of the Access of Information Law. The results about the manager perceptio demonstrate a tendency in publishing the produced information, however, elements such disorganization of information in the portals, lack of standardization of the virtual structure and type of language to use, and lack of procedures of popular participation and interaction in the portals are determiners to bring problems in the access and in the communication with the public. Besides, the short time of institutions’ creation and the short time of the managers assuming their functions must be considered as a reflex of the found results. Therewith, the present study highlighted the importance of Public Transparency theme and it reached a positive result to a scientific and social contribution.

Estudo da efetividade dos mecanismos de compartilhamento de memória em hipervisores

The growing demand for large-scale virtualization environments, such as the ones used in cloud computing, has led to a need for efficient management of computing resources. RAM memory is the one of the most required resources in these environments, and is usually the main factor limiting the number of virtual machines that can run on the physical host. Recently, hypervisors have brought mechanisms for transparent memory sharing between virtual machines in order to reduce the total demand for system memory. These mechanisms “merge” similar pages detected in multiple virtual machines into the same physical memory, using a copy-on-write mechanism in a manner that is transparent to the guest systems. The objective of this study is to present an overview of these mechanisms and also evaluate their performance and effectiveness. The results of two popular hypervisors (VMware and KVM) using different guest operating systems (Linux and Windows) and different workloads (synthetic and real) are presented herein. The results show significant performance differences between hypervisors according to the guest system workloads and execution time.

Governança ambiental e turismo: a participação de atores no Parque Nacional Tortuguero, Costa Rica

A experiência na construção da governança ambiental em torno do Parque Nacional Tortuguero na Costa Rica é a questão principal deste artigo. A mesma será analisada a partir da implementação do Conselho Local de Tortuguero/Setor Oeste e das articulações de atores do Setor Costeiro, notadamente, onde há incidência maior de turismo. Estruturou-se este artigo com base em pesquisas qualitativas, a exemplo de coleta de informações da bibliografia especializada, de dados documentais, legais e também via entrevistas. Por meio de tais movimentos, identificou-se uma série de ações relacionadas à conservação do meio ambiente e do turismo, dentro de uma perspectiva sustentável. Entretanto, em que pese os avanços alcançados, constata-se ainda a necessidade de se empreender mais esforços por parte de todos os envolvidos, sobretudo do Estado e na sua interação com os demais atores, pois persistem problemas diversos que são, historicamente, são insustentáveis a pensar-se em manejo do meio ambiente.
