Production of academic knowledge in the past two centuries has been marked by a clear trend towards specialization. The considerable importance currently gained by environmental issues, as seen through the lense of sustainable development, has promoted significant changes in this scenario and highlighted the need for interdisciplinary approaches (de-specialization). The recent creation of interdisciplinary master's and doctoral training programs in Brazil faces a range of obstacles related to the general crisis prevailing in University. Using examples taken from Brazilian graduate programs, our paper outlines and analyzes critically the programs focused on environmental issues nationwide and shows the significant limitations and challenges incurred in building this new field of knowledge. Despite a growing trend towards "environmentalization" of some disciplines, the issue at stake is to interdisciplinarize the focus on sustainable development. The consolidated programs are presented according to the specific institutional arrangements adopted by them. They clearly reflect a need to act creatively in order to break through the impenetrable structure of disciplinary departments. To conlcude, the idea of building a network structure within University is argued as a possible alternative, a solution that does not deny the role of traditional departments, but opens spaces for their interaction with interdisciplinary units and programs.

This paper compares anti-hookworm campaigns conducted in the early twentieth century in France, Germany, Brazil and West India. The populations that suffer from hookworm are not identical in the North and in the South. In tropical and semi-tropical regions hookworm is mainly found among poor peasants and is related to lack of hygiene, while in temperate climates hookworm was a professional disease of miners, a highly organized professional segment. Nevertheless, major disparities in the pattern of hookworm control did not reflect the North-South divide, but a difference between campaigns. These aimed at the eradication of hookworm infection (Germany and West-India) and at alleviating the effects of this infection on populations (France and Brazil). Maps that represented the prevalence of hookworm mirrored the aims of the sanitary campaign in which they were used: eradication of parasitic worms versus the reduction of the handicap induced by these worms. In public health as well, representing is intervening. And vice versa: patterns of intervention shape representations. [ABSTRACT FROM AUTHOR]
