Are there dual labor markets in Chile?: Empirical evidence
(Elsevier, 1996)
In this paper we use a switching regression method to test the hypothesis that segmentation in the Chilean labor market exists. The results support the labor segmentation hypothesis and consequently they contradict those ...
Inflection and stability points of diphasic logistic analysis of growth
(Univ Sao Paolo, 2015-05-01)
Growth functions with inflection points following a diphasic model, can be adjusted by two approaches using segmented regression or the sum of two functions. In both cases, there are two functions, one for each phase, with ...
Automatic Segmentation of Exudates in Ocular Images using Ensembles of Aperture Filters and Logistic Regression
(IOPScience, 2013-10)
Hard and soft exudates are the main signs of diabetic macular edema (DME). The segmentation of both kinds of exudates generates valuable information not only for the diagnosis of DME, but also for treatment, which helps ...
State segmentation in unequal democracies
(2019)
This paper introduces the concept of state segmentation and relates it to a causal argument for
why unequal democracies survive. State segmentation describes asymmetries between the
efficiency of citizenship rights for ...
Regression of intestinal metaplasia to cardiac or fundic mucosa in patients with Barrett's esophagus submitted to vagotomy, partial gastrectomy and duodenal diversion. A prospective study of 78 patients with more than 5 years of follow up
(MOSBY, INC, 2006-01)
Background. Regression of intestinal metaplasia to cardiac mucosa in patients with Barrett's (BE) esophagus could alter the natural history of BE.
Objective. To determine the regression of intestinal metaplasia to cardiac ...
Critical points in logistic growth curves and treatment comparisons
(Universidade de São Paulo (USP), 2012-01-01)
Several biological phenomena have a behavior over time mathematically characterized by a strong increasing function in the early stages of development, then by a less pronounced growth, sometimes showing stability. The ...

Response plateau models fitting via isotonic regression
(UNIV FEDERAL SANTA MARIASANTA MARIA, 2013-08-02)
Within the nutritional context, the supplementation of microminerals in bird food is often made in quantities exceeding those required in the attempt to ensure the proper performance of the animals. The experiments of type ...
