Economia política da arte moderna II/ notas para uma sistematização provisória

Paradigma tradicional de excelência artesanal, com que meios pode a pintura responder à abstração do trabalho e à sua ordenação serial, inerentes à modernização capitalista? O texto presente busca sistematizar os momentos decisivos de um percurso que se estende de Manet (1832-1883) a Rothko (1903-1970). Constitui o capítulo conclusivo de uma investigação sobre a transformação crítica do modo de pintar em modo de fabricação, fundado na superação reflexiva da dicotomia entre trabalho intelectual e corporal, imposta historicamente à sociedade. Atualizada criticamente e assinalando um fecho possível do processo da arte moderna, a pintura de Rothko põe-se como a negação de todo aspecto individual da pintura e de unidade orgânica e monádica da obra. Alcança-se assim o último termo de um processo; termo que assinala o fim do ciclo da autonomia estética como forma ligada à liberdade do sujeito, idealizado como natureza desinteressada. Para o trabalho de resistência contra a aceleração da barbárie é fundamental doravante levar em conta os fatores de heteronomia supraindividuais que, se não logram controlar toda a produção, detêm a hegemonia na esfera da circulação.

An integrated approach to evaluate emerging contaminants in drinking water

The chemical stock of emerging contaminants in Brazilian drinking water is of great interest due to the poor water quality at surface water intakes. In addition, little is known about the effect of some contaminants, such as endocrine disrupting chemicals (EDCs), which may be present in both raw and treated water. The aim of this work was to evaluate selected emerging contaminants in Brazilian waters using both chemical and biological analyses. Sampling sites were established in different municipalities based upon raw water quality data. Estrone, 17 beta-estradiol, estriol, 17 alpha-ethinylestradiol, bisphenol A, 4-n-octylphenol and 4-n-nonylphenol were determined in the samples by liquid chromatography-tandem mass spectrometry. A yeast assay using a Saccharomyces cerevisiae bioluminescent bioreporter was used to evaluate the estrogenic activity of the water samples. The first integrated results revealed similarities between the two individual approaches, since higher values for the bioassay were accompanied by significant concentrations of some selected compounds in surface water samples. No estrogenicity was observed for drinking water samples. Our results also indicate that the usual paradigm of evaluating water quality by measuring selected EDCs in a given water sample via chemical analysis, needs to be reviewed since the observed estrogenicity of a water sample is now a better guiding parameter to the selection of samples and substances to be chemically investigated in further analysis. So far, the data bank produced in this work, i.e., the comparison between chemical burden and observed estrogenicity, is not yet sufficiently robust to fully guide this decision.

Challenges for Brazilian MNCs' international human resources management

Multinationals from emerging countries such as Brazil now take the path of internationalisation where early movers have already been. However, these companies have to develop new tools to deal with their own challenges, since they come from countries with different historical backgrounds and specificities. This paper explores challenges for Brazilian MNCs in terms of HRM when operating abroad. It presents the results of six cases of Brazilian MNCs through a grounded theory study. Results show these companies had to deal with their former economic turbulence, shortage of qualified workforce to work internationally and the need to develop HRM competencies to operate globally.

White paper sobre Open Source, Open Access, open Standards e o futuro da catalogação

The discussions on the future of cataloging has received increased attention in the last ten years, mainly due to the impact of rapid development of information and communication technologies in the same period, which has provided access to the Web anytime, anywhere. These discussions revolve around the need for a new bibliographic framework to meet the demand of this new reality in the digital environment, ie how libraries can process, store, deliver, share and integrate their collections (physical, digital or scanned), in current post-PC era? Faced with this question, Open Access, Open Source and Open Standards are three concepts that need to receive greater attention in the field of Library and Information Science, as it is believed to be fundamental elements for the change of paradigm of descriptive representation, currently based conceptually on physical item rather than intellectual work. This paper aims to raise and discuss such issues and instigate information professionals, especially librarians, to think, discuss and propose initiatives for such problems, contributing and sharing ideas and possible solutions, in multidisciplinary teams. At the end is suggested the effective creation of multidisciplinary and inter-institutional study groups on the future of cataloging and its impact on national collections, in order to contribute to the area of descriptive representation in national and international level
