13. Survival of women with cancer in palliative care : use of the Palliatives Prognostic Score (PaPScore) in a population of Brazilian women / Sobrevida em mulheres com cancer em cuidados paliativos : o uso do Palliatives Prognostic Score (PaPScore) em uma população de mulheres brasileiras
Introduction: The accurate prediction of survival time in terminal cancer patients is difficult but critically important, helping patients and their families develop goals and priorities, directing implementation of the most appropriate therapy and permitting the correct use of existing resources. Many studies have been developed in an attempt to improve pro

14. AVALIAÇÃO DE RECURSOS DE PETRÓLEO NÃO DESCOBERTOS: METODOLOGIA E MÉTODOS DE ELICIAÇÃO DE INFORMAÇÕES SUBJETIVAS / ASSESSING UNDISCOVERED OIL AND GAS RESOURCES: METHODOLOGY AND ELICITATION OF SUBJECTIVE INFORMATION
A avaliação de recursos petrolíferos não descobertos, isto é feita a partir de informações obtidas de testes indiretos como a sismografia, é a base para as decisões sobre a perfuração de poços de exploração. As informações disponíveis nessa fase que antecede a perfuração de poços são vagas e plenas de incertezas. Por outro lado, a avalia

15. Beliefs/representations about tobacco addiction a study on the vulneral adolescents to tobacco use / Tabagismo: uma busca da subjetividade no uso da droga permitida
The use of tobacco is the most serious problem in Public Health. Studies show the early consumption in adolescence and the factors that predispose this consumption and/or nicotine dependece. Currently, there are Laws, which regulate advertisements and public locations on tobacco use. Interdisciplinary approaches seeking methodological links among these diver

16. Probabilidades: a visão laplaciana e a visão freqüentista na introdução do conceito
From her origin, the concept of probabilities grew in multiple perspectives: concretely, the probability of an event or phenomenon has been conceived in a classic slope or laplaciana (based on the "Law of Laplace"), in a slope based on the relative frequency of the event in study (based on the "Law of the Great Numbers" of Jacques Bernoulli) and in a slope p

17. Inference from Inadequate and Inaccurate Data, III*
Having measured D numerical properties of a physical object E which requires many more than D parameters for its complete description, we want to estimate P other numerical properties of E. Continuing the discussion in papers I1 and II,2 the present paper gives estimates when we believe it likely that we can guess an upper bound M on the Hilbert norm not of

18. Conditioned Behavior in Drosophila melanogaster
Populations of Drosophila were trained by alternately exposing them to two odorants, one coupled with electric shock. On testing, the flies avoided the shock-associated odor. Pseudoconditioning, excitatory states, odor preference, sensitization, habituation, and subjective bias have been eliminated as explanations. The selective avoidance can be extinguished

19. Prevalence of back pain among fulltime United States workers.
A source of data on the health and working conditions of a probability sample of United States workers, the Quality of Employment Survey for 1972-3 (QES73), is investigated for the first time to determine which groups of workers are more or are less likely to report back pain. Estimated coefficients from a logistic regression are used to calculate odds ratio

20. Objective detection of hemifield and quadrantic field defects by visual evoked cortical potentials.
AIMS/BACKGROUND: An objective method for detecting hemifield and quadrantic visual field defects has been developed using steady state visual evoked cortical potentials (VECPs), an adaptive noise canceller (ANC), and Hotelling's t2 statistic. The purpose of this study was to determine the sensitivity and specificity of the technique. METHODS: Nine subjects (

21. Cardiovascular and sweating dysfunction in patients with Holmes-Adie syndrome.
A cross-sectional study is reported in which 53 patients with Holmes-Adie syndrome have been subjected to a battery of tests of autonomic nervous function referable to the cardiovascular system, to two objective tests of sweating function, and to subjective assessment of sweating by application of quinizarin powder followed by body heating. The majority of p

22. Failure to handle more than one internal representation in visual detection tasks
Perceptual studies make a clear distinction between sensitivity and decision criterion. The former is taken to characterize the processing efficiency of the underlying sensory system and it increases with stimulus strength. The latter is regarded as the manifestation of a subjective operation whereby individuals decide on (as opposed to react reflexivel

23. Tumor angiogenesis as a predictor of recurrence and survival in patients with node-negative colon cancer.
OBJECTIVE: The authors' objective was to quantitatively assess angiogenesis or neovascularity within node-negative colon cancers and to determine if increased angiogenesis correlated with higher recurrence and lower survival rates. SUMMARY BACKGROUND DATA: Neovascularization promotes rapid tumor growth by facilitating nutrient and metabolite exchange. Recent
