This study, a qualitative investigation anchored in Foucaltian analysis with approximations to post-structuralist theory, explores the question of autonomy as one of the tensions of nursing performance/knowledge which can be discursively articulated to bioethics and to techno biomedicine. From such perspective, from the multiples vies that may emerge to completing a critical reading of the analyzed texts (articles produced by nurses) and of the interviews with intensive care nurses, the theme of autonomy was analytically explored from the concept of self care, unfolding itself into categories which express privileging: morals as obedience to the Law; conduct and morals concerning technical knowledge; self-governing in its confront with technique. These are configured as ethical possibilities for the intensive care nurse/subject, not as sequential or competitive stages, but connected and confluent in the experience of the current historical period.

Neoseiulus HUGHES, 1948 is currently one of the largest genus of Phytoseiidae Berlese. Neoseiulus demitei sp. nov., a new species of phytoseiid mite from Rio Grande do Sul State, Brazil, is illustrated and described based on specimens collected on Tibouchina sp. (Melastomataceae) plants. This new species differs from others by having most of propodossomal setae reaching the base of nearby setae and a constriction of ventrianal shield at level of preanal pores. Nevertheless, this new species is the first of the species subgroup kennetti described from Brazil. A key of Neoseiulus species reported in Brazil is also included. Source

Natural rubber latex was submitted to epoxidation reaction to establish the best reaction conditions without the occurrence of side reactions, which promote coagulation of the latex and development of an agglomerate of rubber. Epoxy groups were produced by in situ epoxidation with formic acid and hydrogen peroxide. The samples were characterized qualitatively by Fourier Transform Infrared (FTIR) analysis and the degree of modification determined by Hydrogen Nuclear Magnetic Resonance Spectroscopy (1H-NMR) analysis. A linear increase in the glass transition temperature (Tg) was observed. The results show that the epoxidation of natural rubber latex is possible and depends on the reaction conditions. Source

Respective literatures on sustainable business models (SBMs) and the bottom of the pyramid (BOP) share the assumption that organizations can contribute to value creation for both business and society. The premise of a win-win solution for multiple stakeholders relies mostly on market-oriented solutions, giving little attention to the role that government programs and regulations may have in promoting such initiatives. At best, literature considers government as an obstacle to the development of SBMs in the BOP context. In this paper, we challenge that view by presenting the case of the Ecoelce project, an SBM developed in the BOP context of Northeastern Brazil. We show that this project transformed a coercive pressure from the Brazilian government into a strategic opportunity and a source of shared value. We argue that the mobilization of native capability was key in this process. © 2016 Elsevier Ltd. Source

In order to describe adequacy of weight gain during pregnancy and its association with pre-pregnancy nutritional status and other factors, a cohort study of pregnant women enrolled at 16-36 weeks of gestation and followed up until delivery was carried out in prenatal care in primary care services in Rio Grande do Sul State, Brazil. Maternal weight was recorded at each prenatal care visit. Weight gain was classified as "adequate," "insufficient" or "excessive" (Institute of Medicine). Poisson regression was used to measure the associations. The sample was comprised of 667 women, and insufficient and excessive weight gain incidences were 25.8% and 44.8%, respectively. Overweight and obese before pregnancy had a significant increased risk of excessive weight gain in pregnancy (RR: 1.75; 95%CI: 1.48-2.07, RR: 1.55; 95%CI: 1.23-1.96, respectively). Women with fewer than six prenatal visits had a 52% increased risk for weight gain below recommended values. Although insufficient weight gain may still be a public health problem, excessive gain is becoming a concern that needs immediate attention in prenatal care. Source
