This dissertation enfoca the relationship between technological competences accumulation and the learning underlying processes. This relationship is examined in the company AGCO Comércio and Indústria Ltda, during the period of 1970 to 2000. It is of a company metal-mechanics, agricultural machines manufacturer. In other words, the dissertation examines the processes technological learning implications for aA technological competences accumulation in the company in study. The dissertation enfoca the competences accumulation for three technological functions: processes and organization, products and equipments. The learning processes are examined to the light of four characteristic: variety, intensity, operation and interaction, from the structure existing analysis use in the literature. Based on study of individual case, this study found that the technological competences ways to accumulation in the studied company are associates to the several processes used to acquire technological knowledge and converts him in organizacional. Ademais, the simple incidence of these processes in the company didn't guarantee in the company a positive implication for the technological competences accumulation. The company accumulated level middleman-superior technological competence (level 6) to accomplish production and function products function processes and organization activities, and intermediary level (level 5) to accomplish function equipments activities. In haves to characteristic key, the learning processes introduce an oscillation differentiated along time: the variety oscillated of moderated the several; the intensity of intermittent the continuous; the operation of bad the good; and the interaction of weak the strong. Through the existing structure use in the literature, however applied to a previous studies different industry, this dissertation suggests that must there be an organized , continuous effort and integrated for the knowledge generation and sowing in every company in order to the technological training accumulation be accelerated in the company.

Este trabalho procura identificar a relação entre dispersão da propriedade acionária e remuneração de executivos. A literatura sugere que, devido a problemas de ação coletiva e custos de agência, companhias com propriedade acionária mais dispersa tendem a remunerar melhor seus executivos. Utilizando dados disponíveis pela primeira vez no Brasil, este trabalho procura testar essa hipótese. Os testes econométricos realizados, com base em uma amostra de 315 companhias abertas brasileiras cujas ações são admitidas à negociação em bolsa de valores, evidenciam uma forte correlação, positiva e estatisticamente significante, entre a remuneração dos administradores e a dispersão acionária. O trabalho conclui que, ceteris paribus, companhias com propriedade acionária mais dispersa pagam remuneração maior a seus administradores.

In this article we show that among elementary school students in Brazil there is a negative and significant relationship between within-class age dispersion and pupil’s proficiency. The relationship between the age-grade delay and school proficiency is usually explained by several factors that influence the educational process, since both student’s age-grade and his/her proficiency reflect difficulties implicit in the child's life. However, we show that the negative relation between within-class age dispersion and individual proficiency can be mitigated by the presence of teachers with high levels of certain attributes, such as teaching experience and years of schooling. This relationship supports the hypothesis that the greater the within-class age dispersion, the difficulties of implementing uniform learning projects are more significant, considering that there is a greater diversity of interests. Therefore, under those circumstances the role of the teacher in class seems to be essential to minimize any negative effect that age diversity may have on individual performance.

O trabalho visa mensurar os efeitos das transferências intergovernamentais sobre as políticas públicas voltadas à educação fundamental. A hipótese que investigamos é a de que as transferências incondicionais aumentam a variabilidade das políticas públicas adotas, enquanto as transferências condicionais diminuem a variabilidade das políticas, já as transferências semi-condicionais afetam as políticas públicas de modo intermediário entre esses extremos. Com base nestes argumentos desenvolvemos estratégicas empíricas baseadas em métodos de regressão em painel, com uso de variáveis instrumentais e de designs descontínuos de regressão.
