Professora ou Tia? A polêmica formação do professor do primeiro segmento do Ensino Fundamental

Investigar a percepção que os professores das séries iniciais do Ensino Fundamental dacidade do Rio de Janeiro têm sobre a importância de sua formação para o desenvolvimentodas futuras gerações foi o objetivo desta pesquisa acadêmica. Muito se tem falado nosúltimos tempos sobre a necessidade de mudança na formação de professores. Na segundametade do século XX, a sociedade brasileira assistiu a transformações constantes ocorridasem seus diferentes setores, alguns dos quais historicamente co-responsáveis, junto com aescola, pelo desenvolvimento educacional a família e a Igreja. A sociedade foi tambémtestemunha do avanço das novas tecnologias, principalmente as da comunicação e dainformação que fizeram da mídia outro setor de fundamental importância para a educaçãode crianças e jovens. São mudanças que obrigam a um novo paradigma de professor,detentor de competências diferenciadas para o eficaz desenvolvimento do fazer docente. Natentativa de atingir o objetivo proposto desenvolvemos três capítulos. O primeiro focouprincipalmente a base teórica, que teve como maior sustentação as idéias de PierreBourdieu sobre o capital cultural. No segundo capítulo foi empreendida uma revisão datrajetória da representação social do professor, por meio de um levantamento da história eda legislação voltada para a formação desse profissional, procurando chamar atenção paraas exigências atuais percebidas por Edgar Morin, Jacques Delors e Philippe Perrenoud. Noúltimo capítulo foi apresentada a pesquisa feita com professores da rede oficial da cidadedo Rio de Janeiro, não perdendo de foco as teorias estudadas.

Public debt sustainability and endogenous seignorage in Brazil: time-series evidence from 1947-92

Using national accounts data for the revenue-GDP and expenditure GDP ratios from 1947 to 1992, we examine two central issues in public finance. First, was the path of public debt sustainable during this period? Second, if debt is sustainable, how has the government historically balanced the budget after hocks to either revenues or expenditures? The results show that (i) public deficit is stationary (bounded asymptotic variance), with the budget in Brazil being balanced almost entirely through changes in taxes, regardless of the cause of the initial imbalance. Expenditures are weakly exogenous, but tax revenues are not;(ii) a rational Brazilian consumer can have a behavior consistent with Ricardian Equivalence (iii) seignorage revenues are critical to restore intertemporal budget equilibrium, since, when we exclude them from total revenues, debt is not sustainable in econometric tests.

Growth, increasing returns, and public infrastructure : time series evidence

Initial endogenous growth models emphasized the importance of external effects and increasing retums in explaining growth. Empirically, this hypothesis can be confumed if the coefficient of physical capital per hour is unity in the aggregate production function. Previous estimates using time series data rejected this hypothesis, although cross-country estimates did nol The problem lies with the techniques employed, which are unable to capture low-frequency movements of high-frequency data. Using cointegration, new time series evidence confum the theory and conform to cross-country evidence. The implied Solow residual, which takes into account externaI effects to aggregate capital, has its behavior analyzed. The hypothesis that it is explained by government expenditures on infrasttucture is confIrmed. This suggests a supply-side role for government affecting productivity.

Public debt sustainability and endogenous seigniorage in Brazil: time-series evidence from 1947-92: revised version

Using national accounts data for the revenue-GDP and expenditureGDP ratios from 1947 to 1992, we examine three central issues in public finance. First, was the path of public debt sustainable during this period? Second, if debt is sustainable, how has the government historically balanced the budget after shocks to either revenues or expenditures? Third, are expenditures exogenous? The results show that (i) public deficit is stationary (bounded asymptotic variance), with the budget in Brazil being balanced almost entirely through changes in taxes, regardless of the cause of the initial imbalance. Expenditures are weakly exogenous, but tax revenues are not; (ii) the behavior of a rational Brazilian consumer may be consistent with Ricardian Equivalence; (iii) seigniorage revenues are critical to restore intertemporal budget equilibrium, since, when we exclude them from total revenues, debt is not sustainable in econometric tests.
