This research discusses contextual factors that influence the development of complementary and/or integrative therapies developed by local health units on street-level bureaucracy in Santos. Through a qualitative approach, the research verifies that street-level bureaucracy is free to suggest and implement the aforementioned therapies, even if they do not have formal support of the municipality; however, they need support from their immediate local supervisors so they can adjust and implement the practice’s routine, or the practice might not occur. Additionally, this text also presents guidelines in order to further develop the research.

This paper deals with the likelihood ratio test (LRT) for testing hypotheseson the mixing measure in mixture models with or without structural parameter. The main result gives the asymptotic distribution of the LRTstatisticsunder some conditions that are proved to be almost necessary.A detailed solution is given for two testing problems: thetest of a single distribution against any mixture, with application to Gaussian, Poisson andbinomial distributions; the test of the number of populations in afinite mixture with or without structural parameter.

An explicit formula for the probability that a Brownian motion crosses a piecewise linear boundary in a finite time interval is derived. This formula is used to obtain approximations to the crossing probabilities for general boundaries which are the uniform limits of piecewise linear functions. The rules for assessing the accuracies of the approximations are given. The calculations of the crossing probabilities are easily carried out through Monte Carlo methods. Some numerical examples are provided.
