Recent studies have shown that many physiological and behavioral processes can be characterized by long-range correlations.
The Hurst exponent H of fractal analysis and the fractional-differencing parameter d of the ARFIMA methodology are useful for capturing serial correlations. In this study, we report on different estimators
of H and d implemented in R, a popular and freely available software package. By means of Monte Carlo simulations, we analyzed the performance
of (1) the Geweke—Porter-Hudak estimator, (2) the approximate maximum likelihood algorithm, (3) the smoothed periodogram approach,
(4) the Whittle estimator, (5) rescaled range analysis, (6) a modified periodogram, (7) Higuchi’s method, and (8) detrended
fluctuation analysis. The findings—confined to ARFIMA (0, d, 0) models and fractional Gaussian noise—identify the best estimators for persistent and antipersistent series. Two examples
combining these results with the step-by-step procedure proposed by Delignières et al. (2006) demonstrate how this evaluation
can be used as a guideline in a typical research situation. 相似文献

Tinnitus therapy according to the Heidelberg model of music therapy integrates psychological strategies in order to manage the perception and approaches to tinnitus aimed at curing the underlying somatic disorder. The specific musical therapeutic interventions as well as the postulated specific effective factors are explained. Several multidisciplinary studies support the effectiveness of this form of therapy. The results indicate that the therapy is highly advantageous in terms of treatment duration, effectiveness, and follow-up stability compared to customary interventions. Furthermore, the results of brain imaging strongly suggest the usefulness of further investigations and discussion in the realm of neuronal modeling of chronic tinnitus. 相似文献

According to Stephen Davies, there is no such thing as free beauty. Using actual and imaginary examples, he tries to show that our aesthetic evaluations of objects inevitably pay heed to the kinds to which they belong or in which we judge them to belong. His examples are not as compelling as he thinks, however. Furthermore, nature looked at through a microscope (or a telescope) provides us with a particular class of counter-examples which have not been dealt with by Davies and which put considerable pressure on his account. 相似文献

We model the forgetting of propositional variables in a modal logical context where agents become ignorant and are aware of
each others’ or their own resulting ignorance. The resulting logic is sound and complete. It can be compared to variable-forgetting
as abstraction from information, wherein agents become unaware of certain variables: by employing elementary results for bisimulation,
it follows that beliefs not involving the forgotten atom(s) remain true.

This article analyzes the views of 3 Dutch physicians working in the former Dutch East Indies during the first part of the 20th century. These physicians based ideas about the nature of the normal indigenous psyche on both their analysis of Indonesian individuals suffering from mental illness and on casual observations that represented widely shared cultural stereotypes. On that basis, they advocated a psychological colonial policy, which was to be based on a scientific understanding of the psyche of the Indonesian people. Using these ideas, they advocated political repression, justified inequality and racism, and limited educational opportunities for Indonesians. Representatives of the Indonesian nationalist movement vigorously protested against these ideas. 相似文献
