Ciberdemocracia, participação social e o voto pela internet

O estudo tem por objetivos apresentar e refletir sobre ideias de teóricos e entendimentos de internautas sobre a interface entre política, democracia e tecnologias da comunicação e informação, seus problemas, potencialidades e perspectivas a partir da compreensão de que as novas tecnologias da comunicação revolucionaram e revolucionam a compreensão sobre a participação democrática. Partindo da história da internet e das novas tecnologias procura-se colocar o ciberespaço e a ciberdemocracia como pano de fundo para o exame da possibilidade da utilização do voto através da internet, assim como mostrar que o uso crescente de dispositivos móveis e de aplicativos de compartilhamento de informações estão possibilitando a que as pessoas ganhem mais voz e, com isso, expressar seus descontentamentos e aprovações tanto na dimensão social quanto política. Quanto maior o percentual da população conectada, maior as possibilidades do desenvolvimento de uma consciência política e, com isso, maior formação de sociedades mais transparentes e participativas. A hipótese levantada é que a forma democrática de governo tem nas redes telemáticas um canal complementar de informação para fomentar a participação dos cidadãos em debates sobre questões de governo

A biossegurança nos consultórios públicos e particulares

Biosecurity is currently a concern for all health-related services, including dentistry, since infection control has a relevant importance. In dental practice, health-related occupations have contact with a great number of individuals who are potentially capable to transmit pathogens. This study comprised a descriptive evaluation of the universal precaution measures for infection control adopted by dental practitioners working at public and private offices in the city of Araçatuba, SP. Data collection was performed by a quiz with questions about individual and collective protection equipments. The results showed that the use of caps was reported by 55% of the professionals working at the public sector and 90% for the private sector. The use of masks and gloves was reported by all professionals surveyed; nevertheless, glove change between patients was not reported by 40% of professionals working at the public sector. There were more flaws in public offices as to the use of protective barriers, since except for the use of gloves, gowns and masks, the frequency of use of those barriers was smaller than at private offices.A biossegurança, atualmente, é uma preocupação de todos os serviços relacionados à saúde, neles inclui-se a odontologia, visto que o controle de infecção é de importância relevante. Na prática odontológica, as profissões de saúde têm contato com grande número de indivíduos que podem ser potencialmente capazes de transmitir patógenos. O objetivo do presente estudo foi uma avaliação descritiva da aplicação de medidas de precaução universal para controle de infecção entre cirurgiões-dentistas que atuam em consultórios públicos e particulares do Município de Araçatuba/SP. A coleta de dados foi realizada através de questionários contendo perguntas sobre equipamento de proteção individual e coletiva. Os resultados mostram que o uso de gorro foi relatado por 55% dos profissionais que atuam no serviço público e 90% que atuam no serviço privado. O uso de máscara e o uso de luvas foram relatados pelos 40 profissionais entrevistados, no entanto a troca de luvas entre os pacientes não foi relatada por 40% dos profissionais da rede pública. Conclui-se que ainda o setor público apresenta mais falhas em relação ao uso de barreiras protetoras, pois na maioria das questões abordadas a freqüência do uso dessas barreiras foram menores em relação ao setor privado

Self-medication with antibiotics: identification of risk factors and analysis of the brazilian population’s lifestyle.

Objectives:Measure the prevalence of adult and elderly users of the Brazilian primary healthcare system who self-medicated with antibiotics and identified its association with risk factors for self-medication and lifestyle. Materials and Methods:This is a quantitative, epidemiological study carried out in the Brazilian primary healthcare system. We used a semi-structured questionnaire and the Fantastic Lifestyle Checklist. We carried out a bivariate analysis, a binomial logistic regression, and the Mann-Whitney nonparametric test.Results: Out of the total sample (537 participants), 40.6% used antibiotics without medical prescription in the last 12 months. The dependent variable was associated with the presence of pain (OR=2.390, CI95, 1.414-4.041); storage of leftover antibiotics in the home (OR=2.124 CI95, 1.122-4.021); and use of medicines on someone’s recommendation (OR=1.722, CI95, 1.127-2.631). The group of individuals who used antibiotics without prescription in the last year had the lowest values in all domains assessed by the Fantastic Lifestyle Checklist and had the highest proportions in the final score of “Fair" and "Needs improvement”.Conclusions: A significant proportion of primary health care users in Brazil used antibiotics without medical prescription. Therefore, the population should receive better guidance on the use of antibiotics and greater incentive to develop healthy habits and lifestyle

Social aspects of dental caries in the context of mother-child pairs

The relationship between mother and child in the context of oral health has traditionally been exposed by the scientific literature in microbiology, which lacks a broad and necessary discussion of health and illness seen as processes, both biological and social. Objective: Investigate the family social determinants associated with the caries history of children and the need for dental treatment (NDT) among their mothers was the objective of this study. Material and methods: This research employed a cross-sectional study of mother-child pairs living in southern Brazil. Data collection occurred in public institutions of early childhood education. The instruments included a structured questionnaire administered to mothers and clinical oral examinations of the mothers and children. The social variables considered were marital status, maternal education, number of children, income, employment status, and frequency of visits to a dental professional. The measured outcomes were the maternal NDT and child caries history. Data were analyzed by the chi-square test (χ2) and by discriminant analysis. Results: The final sample consisted of 272 mother-child pairs and it was found that the greatest need for treatment was among mothers with low educational level and low family income who rarely or never visited a dentist. Tooth decay was less frequent in only child, and most frequent in children of mothers with low educational attainment, and in children in lower income households who rarely or never visited the dentist. The social determinants of caries in children and of the maternal NDT were similar. It follows that the maternal NDT and caries history among children were strongly associated with maternal education (

Return of the quantum cosmic censor

The influential theorems of Hawking and Penrose demonstrate that spacetime singularities are ubiquitous features of general relativity, Einstein's theory of gravity. The utility of classical general relativity in describing gravitational phenomena is maintained by the cosmic censorship principle. This conjecture, whose validity is still one of the most important open questions in general relativity, asserts that the undesirable spacetime singularities are always hidden inside of black holes. In this Letter we reanalyze extreme situations which have been considered as counterexamples to the cosmic censorship hypothesis. In particular, we consider the absorption of fermion particles by a spinning black hole. Ignoring quantum effects may lead one to conclude that an incident fermion wave may over spin the black hole, thereby exposing its inner singularity to distant observers. However, we show that when quantum effects are properly taken into account, the integrity of the black-hole event horizon is irrefutable. This observation suggests that the cosmic censorship principle is intrinsically a quantum phenomena.Comment: 5 page
