Persistência e memória longa sazonal na série de desemprego da região metropolitana de São Paulo

Este artigo aborda o tema da persistência na taxa de desemprego da região metropolitana de São Paulo. Foram utilizados modelos SARFIMA de integração fracionária para avaliar a dinâmica de absorção dos choques econômicos pela série de desemprego. A hipótese de histerese no desemprego foi avaliada usando os modelos de memória longa. Os resultados obtidos pelo arcabouço fracionário foram contrapostos aos do paradigma I(1) -I (0) e revelaram a incapacidade dos modelos tradicionais SARIMA de extrair corretamente o comportamento de baixa frequência da série temporal. Verificou-se que o modelo sazonal tradicional induz à superavaliação da persistência na série de tempo estudada.This paper deals with the persistence theme in the unemployment rate of São Paulo metropolitan region. SARFIMA fractional integration models were used to evaluate the dynamics of economic shock absorption by the unemployment series. The hysteresis hypothesis in the unemployment rate was evaluated using long-memory models. The results found using the fractional framework were compared with those of the I(0) -I (0) paradigm, and they showed the inability of the traditional SARIMA models to correctly extract the low-frequency behavior of the time series. It was shown that traditional seasonal model leads to an overvaluation of the persistence in the series

NUMERICAL STUDY OF OIL SPILL IN THE PATOS LAGOON ESTUARY REGION

The consumption pattern of the world population is based on petroleum derivatives, which despite contributing to the improvement of the quality of life, has negative aspects, mainly in the environmental scope. The number of oil spills in water slide has increased significantly in recent years. Considering the complexity of the marine environment, the present work aims to apply a identification system of the dynamics and dispersion of oil, using the numerical modeling in the region of Franceses Bridge, near to Patos Lagoon-RS, Brazil. The study of hypothetical events of oil leakage in the region is of fundamental importance, since the Riograndense Petroleum Refinery is located inside of the Patos Lagoon estuary. A data structure of atmospheric and oceanic circulation was organized and inserted in the coupling between the hydrodynamic module Telemac-3D and the ECOS oil model, during the period between 2010 and 2013. The coupling of these models provided satisfactory results, requiring a level of computational effort favorable to obtaining of results capable of giving technical and scientific support to studies such as those of environmental impacts and contingency plans
