Globalização, desemprego e (nova) pobreza: estudo sobre impactes nas sodiedades portuguesa e brasileira

This article reflects upon the possible connections between the processes of economic globalization, changes in the labour market and the new forms of poverty. The debate is framed by two different economic contexts: Portugal (characterized by slow and insufficient growth rates, a serious social crisis, and difficulties in asserting itself economically and politically in the European and world contexts) and Brazil (a dynamic emerging economy, with high growth rates and receding poverty levels). This allows us to assess some of the economic and social impacts arising from the global pressure to be economically competitive, which have led to new forms of poverty, social precariousness and job insecurity in both societies.

Desempenho de tractores florestais processadores

A time-and-motion study in wood processing of the Eucalyptus harvester's operational cycle was developed. The objective was to evaluate wood harvesters working under several site conditions. The research includes two kinds of harvesters while processing wood to supply paper and cellulose factories, as follows: a machine with twin tires and other one with large tracks, both connected to a different head harvester models. The forestry species were Eucalyptus saligna Smith and Eucalyptus grandis Hill ex Maiden, seven and eight years old, in slope terrains ranging from 0% to 10% degrees, under harvesting systems used by Votorantim and Suzano forestry companies, in São Paulo State, Brazi. Considering all field research, results disclosed that, for some conditions, both machines have shown mathematical correlation between some mechanical wood operation within the processing operational cycle and the saw logs production. All the mathematical correlations were found to express logarithmical models.
