Introdução: A Avaliação objetiva é um valioso recurso na pesquisa. Contudo, o estesiômetro provê informações por cores. Objetivo: Apresentar a conversão logarítmica dos valores nominais do estesiômetro como opção representativa de registro na avaliação de prejuízo tátil. Método: Estudo Piloto aprovado com parecer nº 1.337. 714, realizado de agosto de 2018 a julho de 2019. Valores nominais (gF) dos monofilamentos do estesiômetro foram convertidos em logaritmo, o procedimento serviu para o registro e o acompanhamento de pacientes cerebrovasculares em reabilitação (n=13), comparado ao controle (n=10), para notações de qualidade, acurácia e poder de inferências dos dados na representação do estado tátil. Statistical analysis performed by the GraphPad Prism 6.0 Program. Resultados: As opções numéricas trabalhadas conseguem representar a percepção da sensibilidade tátil, sendo que a conversão em logaritmo demonstra objetividade, sensibilidade, coerência e consistência para gerar mais inferências. Conclusão: A notação logarítmica para registro da sensibilidade é uma opção versátil de análise e interpretação dos dados na pesquisa em reabilitação.

If we make a set of measurements, such as narrow-band or multicolour photo-electric measurements, which are designed to improve a scheme of classification, and in particular if they are designed to extend the number of dimensions of classification, i.e. the number of classification parameters, then some important problems of analytical procedure arise. First, it is important not to reproduce the errors of the classification scheme which we are trying to improve. Second, when trying to extend the number of dimensions of classification we have little or nothing with which to test the validity of the new parameters.Problems similar to these have occurred in other areas of scientific research (notably psychology and education) and the branch of Statistics called Multivariate Analysis has been developed to deal with them. The techniques of this subject are largely unknown to astronomers, but, if carefully applied, they should at the very least ensure that the astronomer gets the maximum amount of information out of his data and does not waste his time looking for information which is not there. More optimistically, these techniques are potentially capable of indicating the number of classification parameters necessary and giving specific formulas for computing them, as well as pinpointing those particular measurements which are most crucial for determining the classification parameters.

Spectrum Imaging

As interest for parallel EELS spectrum imaging grows in laboratories equipped with commercial spectrometers, different approaches were used in recent years by a few research groups in the development of the technique of spectrum imaging as reported in the literature. Either by controlling, with a personal computer both the microsope and the spectrometer or using more powerful workstations interfaced to conventional multichannel analysers with commercially available programs to control the microscope and the spectrometer, spectrum images can now be obtained. Work on the limits of the technique, in terms of the quantitative performance was reported, however, by the present author where a systematic study of artifacts detection limits, statistical errors as a function of desired spatial resolution and range of chemical elements to be studied in a map was carried out The aim of the present paper is to show an application of quantitative parallel EELS spectrum imaging where statistical analysis is performed at each pixel and interpretation is carried out using criteria established from the statistical analysis and variations in composition are analyzed with the help of information retreived from t/γ maps so that artifacts are avoided.

A focus on the study of development and other kinds of changes in the whole individual has been one of the hallmarks of research by Magnusson and his colleagues. A number of different approaches emphasize this individual focus in their respective ways. This presentation focuses on intraindividual variability stemming from Cattell's P-technique factor analytic proposals, making several refinements to make it more tractable from a research design standpoint and more appropriate from a statistical analysis perspective. The associated methods make it possible to study intraindividual variability both within and between individuals. An empirical example is used to illustrate the procedure.
