Bromelia serra Griseb. (Bromeliaceae) es una hierba terrestre que habita en el sotobosque de bosques abiertos del Chaco y el Cerrado. En este trabajo se analizó el efecto de la temperatura, el clima lumínico y la escarificación sobre la germinación de semillas. Se evaluaron dos regímenes de temperatura (15/20 ºC y 20/30 ºC), tres ambientes lumínicos (Luz, Filtro y Oscuridad; 100% luz y 0.65 R:FR, 100% luz y 0.09 R:FR y sin luz respectivamente) y dos tratamientos de escarificación (Escarificación durante 1 min. con H2SO4 al 30% y Control sin escarificar). La temperatura fue un factor clave ya que solo se registró germinación (una reducida fracción de las semillas y en forma lenta) en el tratamiento a 20/30 ºC. Las semillas fueron indiferentes a la intensidad de luz, germinando tanto en condiciones de luz como de oscuridad. La calidad de la luz afectó la germinación, registrándose mayores porcentajes de germinación a altas relaciones R:FR. No se detectaron efectos de la escarificación en la germinación de las semillas. Los resultados de este trabajo aportan información básica sobre la germinación de semillas, que resultan útiles para el manejo de la especie.

Macro-analysis, regulation and the method: an alternative to the methodological holism and individualism to a historical and institutionalist macro-economy. The paper examines the epistemological conditions that make the "regulationist" macro-analysis a possible alternative to the traditional equilibrium approaches. It shows how these analyses allow to overcome the structure-agent dilemma as from the concept of contextual rationality and of a hol-individualist methodology that, combined with the notion of strong historicity, find wide theoretical basis in Bourdieu's sociology, in Braudel's works on economical history and in Lukács's ontology on the social being. The paper also explains its historical origins and concludes with a synthesis of the method and the necessary steps to accomplish this type of macroeconomics approach.

This paper explores the problems of an unstable regulatory regime in network industries and addresses the tension between the necessary flexibility in the long-term regulatory commitment and the need for institutional stability. A draft statute that substantively changes the initial terms under which fixed telecommunications services have been transferred to private companies - currently under discussion in the Brazilian Congress - is presented as an example of that tension. Some alternative proposals to tackle with universal service challenges - the underlying problem behind the mentioned draft statute - are presented in the end.

O presente trabalho tem por objetivo apresentar algumas idéias sobre o tema do treinamento corporal e sua relação com o domínio da natureza. Para isso apresenta-se a teoria da formação do sujeito e da civilização desenvolvida por Theodor W. Adorno e Max Horkheimer, sobretudo na Dialética do esclarecimento. A ênfase recai sobre o papel do sacrifício nesse processo, e a relação deste com o corpo. A partir daí procura-se entender o esporte, e dentro dele o treinamento corporal, com vistas a desenvolver uma análise daquele baseada na lógica sacrificial e na correspondente redução do corpo a uma naturalidade desqualificada e fungível.

There has been considerable debate over whether corporal punishment against children should be prohibited in Canada. Various organizations, most notably the Canadian Foundation for Children, Youth and the Law, have argued that the Canadian Government should ban the use of corporal punishment by repealing the specific section of the Canadian Criminal Code that provides parents with a legal defence to use corporal punishment against their children; this provision is outlined in Section 43 of the Criminal Code. Recently, the Canadian Foundation for Children, Youth and the Law challenged the constitutionality of Section 43 before the Supreme Court of Canada. The organization claimed Section 43 is unconstitutional. It violates children's Charter rights, such as the right to security of a person (Section 7), the right to be protected from cruel and unusual treatment (Section 12), and denies children the same protection adults receive under the law. Both the Canadian government and the Supreme Court of Canada reject the Foundation's arguments. Examining the federal government and the judicial system's rationale for refusing to remove Section 43 of the Canadian Criminal Code discloses how the parent-child relationship is perceived. This thesis examines how the parent-child relationship is perceived by the Canadian government and the issues that arise from such a view. This examination is essential for the comprehension of why Canada's corporal punishment law was enacted and remains in effect today.
