AIM: To assess sociodemographic and behavioural risk factors for periodontal attachment loss (PAL) progression after 5 years in an urban sample from south Brazil. METHODS: At baseline, 1586 subjects, 14 years and older, were derived using a multistage probabilistic sample strategy. At follow-up, 653 of 755 subjects had >/=6 teeth and were included in this analysis. A modified multiple Poisson regression was used to calculate adjusted relative risks (RR) and 95% confidence intervals (CI). RESULTS: Overall, 247 (37.8%) subjects exhibited PAL progression >/=3 mm in >/=4 teeth. Subjects older than 30 years had approximately two times higher risk of having PAL progression than younger subjects. Subjects with low education had 53% higher risk (RR = 1.53; 95% CI:1.06-2.22) of PAL progression compared to those with high education. A significant interaction between gender and smoking was observed. Among never-smokers, males were 33% more likely (RR = 1.33; 95% CI:1.06-1.66) to experience PAL progression than females. Among smokers, there was 8% increased risk of PAL progression (RR = 1.08; 95% CI:1.01-1.14) for males and 21% (RR = 1.21; 95% CI:1.11-1.33) for females per 10 packyears. Skin colour, socioeconomy, dental care and diabetes were not significantly associated with PAL progression after statistical adjustment. CONCLUSION: Sociodemographic factors and smoking are independent risk factors for PAL progression in this Brazilian population.

Este artigo pretende retomar a interpretação que pode ser chamada de tradicional das três condições do ato propriamente virtuoso expostas em  EN II 4, i.e., o conhecimento, escolher deliberadamente o ato por ele mesmo e seguir-se de uma disposição firme e não hesitante. A atenção da análise será voltada à primeira e à terceira condição. Buscar-se-á mostrar que a condição do conhecimento pode ser compreendida como conhecimento das circunstâncias, do ato ele mesmo como virtuoso e das técnicas ou ofícios que podem ser por ele requeridos. Buscar-se-á igualmente justificar a introdução do termo ‘disposição’ na tradução apresentada, já que o termo grego ‘hexis’ não consta na passagem analisada. Um apontamento será feito, por fim, no sentido de oferecer uma justificativa mais ampla para a interpretação aqui defendida na medida em que a localiza como um posicionamento contrário à concepção intelectualista socrática.

We consider the Fractionally Integrated Exponential Generalized Autoregressive Conditional Heteroskedasticity process, denoted by FIEGARCH(p,d,q), introduced by Bollerslev and Mikkelsen (1996). We present a simulated study regarding the estimation of the risk measure VaRp on FIEGARCH processes. We consider the distribution function of the portfolio log-returns (univariate case) and the multivariate distribution function of the risk-factor changes (multivariate case). We also compare the performance of the risk measures VaRp, ESp and MaxLoss for a portfolio composed by stocks of four Brazilian companies.
