O poder e as injustiças nas pesquisas em seres humanos

Após considerações gerais sobre a ética na pesquisa envolvendo seres humanos, focaliza-se a possibilidade de ocorrências de injustiças, sob a égide de diversas formas de poder. Exemplificam-se situações concretas. Enfatiza-se a análise das possíveis injustiças à luz da Bioética, com destaque para multi e transdisciplinaridade. O autor se posiciona quanto às características atuais da Bioética, cuja ótica levou à elaboração das Diretrizes éticas para a pesquisa envolvendo seres humanos, no Brasil (Resolução 196/96 e complementares do Conselho Nacional de Saúde). Descreve-se a sistemática das atividades do Grupo Executivo de Trabalho - GET, designado pelo Conselho Nacional de Saúde (órgão de controle social na área da saúde), para elaborar as Diretrizes. É dado destaque à participação dos diversos segmentos da sociedade, evidenciando multi e transdiciplinaridade, sob a coordenação do GET, do qual o autor foi Presidente. Comentam-se os principais tópicos das Diretrizes brasileiras, enfocando-se a sua relação com o tema de poder e injustiça. Salienta-se o papel dos Comitês de Ética em Pesquisa - CEP e da Comissão Nacional de Ética em Pesquisa - CONEP.

About the Use of the HdHr Algorithm Group in Integrating the Movement Equation with Nonlinear Terms

This work summarizes the HdHr group of Hermitian integration algorithms for dynamic structural analysis applications. It proposes a procedure for their use when nonlinear terms are present in the equilibrium equation. The simple pendulum problem is solved as a first example and the numerical results are discussed. Directions to be pursued in future research are also mentioned. Copyright (C) 2009 H.M. Bottura and A. C. Rigitano.

Administrative rationality and coping strategies in shift work

Shift work (SW) can affect worker health and productivity. Working at night, workers often accumulate fatigue and are less productive. In Brazil, laws have been drafted aiming to reduce night work and rotating shift hours. In order to slash costs, companies have been looking for new arrangements to improve productivity under these conditions. The purpose of this study was to examine management changes and their outcomes in a large glass factory located in an industrial region of Brazil. The results show that the management, seeking equal productivity among shifts, focused its efforts mainly on distributing employee expertise. The arrangement resulted in 12 different groups that combine to serve three fixed shifts. A same shift can be served by more than one group, and the members of a same group share days off on different days. There was no statistically significant productivity difference among the three shifts. The on-site examination showed that part of the production was held by the workers and transferred to the next shift in order for them to be able to meet the management's performance rate requirements. The finding shows how a Brazilian cultural trait (resistance without conflict) is used to drive coping in SW.

Incidence of high blood pressure in a group of tannery workers in Brazil

O objetivo deste estudo foi medir a incidência de hipertensão arterial sistêmica em um curtume de médio porte em Botucatu, São Paulo, Sudeste do Brasil, onde havia sido observada, em estudo prévio, uma correlação positiva entre tempo de trabalho e níveis pressóricos, bem como uma alta prevalência de hipertensão. Para tanto, uma coorte de trabalhadores desse curtume foi acompanhada durante sete anos. Ao final do seguimento, estimou-se a taxa de incidência de hipertensão arterial como 0,0964.ano-1, valor considerado elevado se comparado com o encontrado em outros grupos profissionais.

Association between diastolic blood pressure and cumulative work time

A pressão arterial diastólica foi analisada enquanto indicador genérico de envelhecimento, e sua associação com o tempo de serviço foi estudada após o controle da idade como possível fator de confundimento. O estudo foi realizado entre operários de um curtume brasileiro em julho de 1993. Foi testada a associação entre pressão diastólica e tempo de serviço, ajustando um modelo de regressão linear de segunda ordem, em que a pressão diastólica era função da idade e do tempo de serviço do operário. Ao ajustar o modelo, pode-se prever que, no início do trabalho no curtume, em média, cada período de um ano está associado com um aumento de cerca de 1,5 mmHg na pressão diastólica. O ajuste obtido realça um componente diretamente associado ao trabalho como parte do coeficiente de aumento da pressão no grupo estudado. Esse componente é o dobro daquele diretamente associado com a idade.

Finite group actions on products of spheres

In this work we make some contributions to the theory of actions of finite groups on products of spheres. Suppose that the group Z(q)(tau) acts freely on the product of k copies of spheres. Question: Is r less than or equal to k? We solve this question for several values of r and k.

Biological and DNA evidence of two dissimilar populations of the Rhipicephalus sanguineus tick group (Acari : Ixodidae) in South America

In this work, the biology, mitochondrial DNA and fertility of hybrids from two strains of Rhipicephalus sanguineus, from Brazil and Argentina, were compared. Engorged larvae, nymphs and adults from Argentina weighed more and the engorgement period of adult females was significantly longer than those of their Brazilian counterparts, whereas adult female tick yield rate was higher for the Brazilian strain. High intraspecific divergence of mitochondrial DNA was detected between R. sanguineus from Brazil and Argentina. on the other hand, a strong genetic relationship was detected between European and Argentinean R. sanguineus populations while the Brazilian population appeared to be related to the African Rhipicephalus turanicus. Adult hybrid females laid eggs, which were mostly unviable, whereas a mean of more than 1400 larvae hatched per egg mass from pure Brazilian and Argentinean strains. These results showed that differences between these strains are greater than previously assumed and that the biosysternatic status of R. sanguineus ticks from South America should be re-evaluated. Wide variations, such as these might account for the reported worldwide differences in biology and vector capacity of this species. (c) 2005 Elsevier B.V. All rights reserved.

Geometrical Lagrangian for a supersymmetric Yang-Mills theory on the group manifold

Perhaps one of the main features of Einstein's General Theory of Relativity is that spacetime is not flat itself but curved. Nowadays, however, many of the unifying theories like superstrings on even alternative gravity theories such as teleparalell geometric theories assume flat spacetime for their calculations. This article, an extended account of an earlier author's contribution, it is assumed a curved group manifold as a geometrical background from which a Lagrangian for a supersymmetric N = 2, d = 5 Yang-Mills - SYM, N = 2, d = 5 - is built up. The spacetime is a hypersurface embedded in this geometrical scenario, and the geometrical action here obtained can be readily coupled to the five-dimensional supergravity action. The essential idea that underlies this work has its roots in the Einstein-Cartan formulation of gravity and in the 'group manifold approach to gravity and supergravity theories'. The group SYM, N = 2, d = 5, turns out to be the direct product of supergravity and a general gauge group g: G = g circle times <(SU(2, 2/1))over bar>.

The influence of study schedules and work on the sleep-wake cycle of college students

College students usually exhibit an irregular sleep-wake cycle characterized by great phase delays on weekends and short sleep length on weekdays. As the temporal organization of social activities is an important synchronizer of human biological rhythms, we investigated the role played by study's schedules and work on the sleep-wake cycle. Three groups of female college students were investigated: (1) no-job morning group, (2) no-job evening group, (3) job evening group. The volunteers answered a sleep questionnaire in the classroom. The effects of day of the week and group on the sleep schedules and sleep length were analyzed by a two way ANOVA for repeated measures. The three groups showed delays in the wake up time on weekends. No-job evening and morning groups also delayed bedtime, but the job evening group slept at the same time on weekdays as on weekends. Sleep length increased on weekends for morning group and job evening group, whereas the no-job evening group maintained the amount of sleep from weekdays to weekends. This survey showed that the tendency of phase delay on weekends was differently expressed according to study's schedules and work.

DIFFERENT MEDIA, DIFFERENT TYPES OF COLLECTIVE WORK IN ONLINE CONTINUING TEACHER EDUCATION: WOULD YOU PASS THE PEN, PLEASE?

This paper presents some findings regarding the interaction between different computer interfaces and different types of collective work. We want to claim that design in online learning environments has a paramount role in the type of collaboration that happens among participants. In this paper, we report on data that illustrate how teachers can collaborate online in order to learn how to use geometry software in teaching activities. A virtual environment which allows that construction to be carried out collectively, even if the participants are not sharing a classroom, is the setting for the research presented in this paper.
