A crise do subprime e seus efeitos sobre os Estados Unidos e reflexos no Brasil

Between December 2007 and June 2009 the United States witnessed 18 months of recession that became known as the subprime crisis. Beginning in the housing market, the crisis moved into the banking and financial markets and spread throughout the entire economy through a domino effect, affecting the majority of other businesses. A major reflection of this was the large rise in unemployment rates due to business slashing jobs in an attempt to preserve cash. Although the crisis has officially ended, the unemployment rate reached over 10% in 2010 in the United States. American's continue to seek new jobs in a very difficult employment market, while attempting to manage the family household budget. American household income, which decreased either by pay cuts, job loss, and the effects of inflation, leads the majority of Americans to declare that the crisis had not yet ended. The crisis has spread to the world in varying degrees. Brazil was one of the countries least affected due to government policies and the large amount of foreign exchange. Although the crisis has affected Brazil only slightly, we will show how it reached this country and how the government solved this problem. This research paper will explain how the subprime crisis began, how it manifested itself in the U.S. economy and throughout the population. Also, it will show the crisis’ effects in Brazil and show some statements from Americans with their respective views and their experiences relative to the crisis

Direcionamento de crédito: uma análise sobre os efeitos da atuação do BNDES durante a crise do Subprime

This essay treats the government acting on the National Financial System (SFN) through the policy of directing credit, a common practice within industrialization attempts. In Brazil this policy occurred mainly through the principal instrument of the government on the financial system, the National Bank of Economic and Social Development (BNDES). It will be explained BNDES’ position within public finances and its ability to mobilize or act as an intermediary for mobilizing resources for the economy. Will also be addressed the countercyclical characteristics of BNDES’ disbursements in the Brazilian economy using as a backdrop the financial crisis that erupted in the overthrow of the mortgages in the USA, also known as the subprime crisis. Finally we will present the main ideas behind the criticism and praise that this model with strong state presence in the financial system suffers

Crise do modelo do jornalismo comercial e emergência do jornalismo cidadão

Corporative media, represented by TV, radio, press and internet conglomerates, is responsible for the biggest portion of audience and public all over the world. The commercial media was built upon media concentration and monopoly strategies and this business aims society’s economic and political control. Unfortunately, they don’t represent the biggest portion of population’s interests and, because of that, corporative media faces a crisis moment while alternative means of communication rise from the initiative of professionals who are committed to society’s marginalized sectors. Radical media intends to express a variant vision about hegemonic policies, priorities and perspectives. Citizen journalism is one of radical media arms and this research proposition is to analyze the business model of commercial media in Brazil and in the world, its means of production, and compare them with citizen journalism methods. This work also intends to analyze radical media and how it is opposite to corporative media by studying Escola de Notícias, an educommunication project from São Paulo

Realidade em crise: uma cobertura in loco da crise econômica na Espanha

Em um contexto globalizado, onde os acontecimentos possuem alcance mundial, torna-se necessário avaliar a eficiência do chamado Jornalismo Internacional na divulgação de informações. A singularidade do olhar jornalístico tem sido comprometida neste ramo, uma vez que a modalidade está cada vez mais ligada às agências de notícias, que apresentam uma cobertura pasteurizada dos assuntos em questão. O objetivo geral deste projeto foi contribuir para o enriquecimento das informações sobre a crise de origem econômica na Espanha, por meio da produção de conteúdo in loco, e retratar os reflexos deste contexto na vida da população europeia, nos âmbitos cultural, econômico, político e social, a fim de comprovar que é fundamental a presença do correspondente no local do assunto reportado. Além disso, constatou-se ser necessário reportar os efeitos da crise na vida comum dos habitantes da Espanha, uma vez que os meios de comunicação tradicionais se limitam a fornecer uma visão tecnicista do assunto, por meio de números e estatísticas. As notas, notícias, entrevistas, fotos e vídeos produzidos foram publicados em uma página experimental criada no Facebook, de modo a avaliar a eficácia das redes sociais enquanto novas plataformas do jornalismo digital

Regeneração avançada sob ilhas de vegetação em área de campo cerrado na estação ecológica de Itirapina, SP

Devido à ação antrópica e consequente fragmentação e degradação do bioma Cerrado, as Unidades de Conservação cada vez mais se inserem como importantes locais de retenção da biodiversidade. A Estação Ecológica de Itirapina apresenta-se como um dos poucos locais do Estado de São Paulo que conservam as diversas fitofisionomias comuns nesse domínio. No intuito de contribuir com informações que auxiliem na conservação e restauração desse bioma, este trabalho traz como questões: as “Ilhas” de Vegetação facilitam o processo de sucessão no Campo Cerrado da Estação Ecológica de Itirapina, SP? Há diferença na regeneração em função da cobertura de copa condicionada pelas espécies formadoras das ilhas estudadas? Para isso, foram selecionadas ilhas com predomínio de Dalbergia miscolobium Benth. (Fabaceae), de Hancornia speciosa Gomes (Apocynaceae) e “Ilhas” Mistas, nas quais levantaram-se todos os indivíduos lenhosos e sublenhosos em parcelas montadas sob sua cobertura de copa e no seu entorno, além de amostrada a cobertura do estrato herbáceo, em função da aplicação do Método do Toque. Comparando-se o entorno e o interior das ilhas analisadas através do uso do Teste t pareado, foram relacionados os componentes diversidade, densidade, riqueza, cobertura do estrato herbáceo, além dos parâmetros de estrutura de habitat: temperatura, luminosidade, umidade do ar e do solo, e biomassa de serrapilheira. Utilizando-se a análise de ANOVA foram usados os mesmos parâmetros para a comparação das ilhas entre si. Alguns resultados nas Mistas, como a diversidade e cobertura do estrato herbáceo (t=5,113; p=0,00373/ t=-3,51; p=0,017, respectivamente), e nas ilhas de Dalbergia miscolobium, como a densidade e a riqueza (t=3,264; p=0,0223/ t=2,850; p=0,0463, respectivamente), associados com análises de estrutura de habitat (para p≤0,06), indicaram...

Posteriormente, se discutiu o impacto desta crise, sobre a segurança alimentar nos países mais afetados e, por fim, foca-se sobre o pouco impacto da crise no caso do Brasil. Analisa-se, portanto, os meios que fizeram com que o Brasil, diferentemente de outros países, conseguisse passar “ileso” pela crise dos alimentos, com relação à economia e a segurança alimentar

Análise exergética e ecológica de um sistema compacto de cogeração operando com gás de síntese

The aim of this work is to make a qualitatively and ecologically evaluation of a compact cogeneration system that operates with synthesis gas obtained from a gasifier. Using the Eucalyptus Biomass as fuel, that passes through a wood gasifier (Drowndraft type) and supply the internal combustion engine. The compact cogeneration system is composed of two heat exchangers, an energy generator connected to an internal combustion engine and an absorption refrigeration system. The complete system is installed in the laboratory from the Energy Department at the University of Guaratinguetá. By the analysis related to the First and Second Thermodynamic Laws applied in this system, was possible to identify the mass flows in each point, energetic efficiency, irreversibility and exergetic efficiency. The components that have the biggest irreversibilities are the gasifier, followed by the internal combustion engine, which should be focused in future improvements. The system efficiency in energetic basis is 51,84% and in exergetic basis is 22,78%. Using the ecologic efficiency methodology was possible to identify the emissions rates, the pollution indicator associated to the combustion of the synthesis gas in the internal combustion engine. The ecologic efficiency considering the energectic analysis is 91,73%, while considering the exergetic analysis, 83,65%. It is concluded that the use of the synthesis gas in a compact cogeneration system is viable from the technical and ecological point of view, making possible to generate energy for isolated communities and promoting the decentralized electricity generation

Crise da cafeicultura e seus efeitos socioeconômicos no município de Dracena (SP)

The coffee crisis in the 1980s reached deeply municipality of Dracena, considering that the coffee had significant social and economic importance to the area. In this context, the research aimed to analyze the socioeconomic consequences that this crisis has provided small rural proprietors of the county. To achieve this goal we seek to articulate the theoretical reference, with data from secondary sources, interviews with the main responsible for the agricultural sector and an application questionnaire to 21 small rural proprietors of the county. It was found that, due to the dependence relationship with the coffee, the economy of the city suffered from the attack of said culture during the 1980s. Rural producers who cultivated such crops as the main, had to readjust productively to remain in the countryside, but the economic and social development that coffee was brought in earlier times was not rescued. As a consequence, there has been an intensification of evasion demographic of rural municipality, a process that had begun in the 1970s and was strongly reinforced by the crisis of the coffee culture. We note that from the 2000s, the situation became better for small rural proprietors in order that public policies implemented now serve, in part, the needs of those with greater efficiency. This situation can be evidenced by a slight reduction in the number of rural people dracenense. Despite improvements recorded since the 2000s, the situation is still not ideal, given that many small proprietors surveyed expressed dissatisfaction. In this context, we note that the performance and joint of federal, state and municipal government are essential so that public policies are efficient, thus providing decent conditions for social reproduction of small rural proprietors and their dependents in the countryside
