Abstract: Abstract: Abstract: The purpose of this paper is to present the results of our research on Internet using by candidates for councilor in Curitiba, Florianopolis and Porto Alegre. From the examination of virtual campaign of candidates who used websites among about 1.400 applicants for the positions for its offices in these capitals, we evaluate the use of these politicians have made the Internet in municipal elections in October 2008. Our basic hypothesis is that the web pages of candidates for elected office, especially the council, served mainly to disseminate traditional political practices, strengthening personalistic and clientelistic ties with the electorate.

Many applications of wireless sensor networks require that nodes, besides monitoring a given phenomenon, must be able to detect and communicate asynchronous events (e.g. alarms), implying that they have to often listen to the medium in idle mode, which is inherently energy wasteful. In such a scenario time synchronization is crucial to efficiently operate in duty-cycles and minimize energy consumption. In this work we assess the impact of the trade-off between spending energy with more frequent synchronizations and in return saving it by reducing the idle listening window necessary for the desired reliability of the communication. The optimal frequency of time synchronizations is obtained analytically and corroborated by numerical results, showing that several times less overall energy may be spent with a finer synchronization when compared with maintaining the minimum clock precision required by the phenomenon being monitored, greatly extending the life-span of the network.

O objetivo deste texto e fazer um estudo do grau de sucesso e fracasso da Federacao das Industrias do Estado do Parana (Fiep) diante das propostas apresentadas na Assembleia Legislativa do Parana na 16a legislatura (2007-2011). Para tanto, analisaremos o indice de convergencia entre posicionamento da associacao industrial paranaense e as proposicoes que tramitaram no Legislativo estadual, apoiando-nos na metodologia desenvolvida por Mancuso (2007) para a analise da acao parlamentar do empresariado em escala nacional. Procuraremos demonstrar duas proposicoes basicas: i. o grau de sucesso do empresariado paranaense e menor do que aquele observado por outros atores do Legislativo federal; ii. o empresariado paranaense pode ser caracterizado como ator politico com baixo grau de capacidade propositiva, mas com elevado poder de veto sobre as propostas que contrariam seus interesses. Dessa forma, buscaremos inserir-nos no debate a respeito da acao politica da acao empresarial no periodo pos-1988, evidenciando algumas de suas singularidades e formas inovadoras de acao coletiva em escala regional.
