Resumo: O estudo teve por objetivo analisar o comportamento das taxas de desemprego regionais no Brasil. Especificamente buscou-se identificar a existência de um processo de convergência e se esse é caracterizado como condicional ou incondicional. A principal inovação consiste em estender esse tipo de análise para as 27 Unidades da Federação. Utilizando testes de raízes unitárias em painel, pode-se fortemente rejeitar a hipótese de presença de raiz unitária, indicando que os choques sobre as taxas de desemprego regionais possuem efeitos transitórios, e a convergência se caracteriza como condicional, o que explica a existência de diferenças estáveis entre os índices de desemprego regionais. As evidências se alinham com a abordagem de equilíbrio ou a Teoria Compensatória, tendo como principais explicações para o fenômeno a preferência dos indivíduos por determinados locais.
A survey of hospitals on three continents was performed to assess their infection control preparedness and measures,
and their infection rate in hospital health care workers during the COVID-19 pandemic. All surveyed hospitals used similar PPE but differences in preparedness, PPE shortages, and infection rates were reported.
Household structure has been recognized as an important element of residential location choice. The aim of this work is to understand how the spatial configuration resulting from these location choices could cause differentials in terms of urban life and opportunities. To do so, a weighted gravitational accessibility index is applied to the São Paulo Metropolitan Area to investigate the differences among household structures to distinct types of accessibility (jobs, education and leisure). The results point to a high disparity between accessibility levels, especially in the accessibility to jobs. The household size plays an important role, with lower accessibility levels associated with more members in the household. The study shows that the household composition also has impacts on accessibility and that higher deprivation levels affect single-parent households.
Decision in urban planning involves an understanding of complex interactions between diff erent aspects of the city. The use spatial decision support systems (SDSS) became an important tool to support decision-making, given its capability to integrate spatial and descriptive data and allow simulation of alternative scenarios. In this work, we present a new tool that reproduces the dynamics of e-commerce and urban logistics and that supports decision making for urban planners. The tool allows for assessment of alternative logistics interventions, considering the effi ciency aspects from the supply side and overall environmental and travel time savings beneï¬ ts from the demand side.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
