1	Endogeneidade da taxa natural de crescimento / Endogeneity of the natural rate of growth Leite, Anna Olimpia de Moura 27 November 2012 (has links) De acordo com León-Ledesma and Thirlwall (2002), o presente trabalho se propõe a testar a endogeneidade da taxa natural de crescimento para um conjunto amplo de países, no sentido do crescimento de longo prazo ser determinado pela demanda. Econometricamente, a principal hipótese a ser testada é a presença de não linearidade na Lei de Okun, que implica na existência de duas taxas naturais, cada uma correspondendo a um regime de crescimento. Utilizando dados anuais para o período de 1980 a 2007 e dados trimestrais para o intervalo entre 1980 e 2011, os resultados corroboram a hipótese de endogeneidade quando aplicada a metodologia proposta por LLT. Esta evidência se repete ao definir exogenamente os regimes de crescimento pelos métodos de Markov-Switching e threshold autoregressive regression (TAR) para os dados anuais, no entanto, para os dados trimestrais há indicações de endogeneidade e exogeneidade da taxa natural de crescimento. / Following León-Ledesma and Thirlwall (2002), this master\'s thesis aims to examine the sensitivity of the natural growth rate to the actual growth rate for a broad set of countries, based on demand-led growth theory. The main hypothesis being tested is the presence of non-linearities in Okun\'s Law, which means the existence of two natural growth rates, each corresponding to a growth regime. Using annual data over the period 1980-2007 and quarterly data over the period 1980-2011, the results support the idea that natural growth rate is dependent of the actual growth rate when applying LLT\'s methodology. This evidence repeats when establishing exogenously the regimes of growth by using Markov-Switching and threshold autoregressive regression (TAR) for the annual data, however for quarterly data this is less straightforward, having indication of endogenous and exogenous natural growth rate.

2	Power Disparities and the Structure of Childrearing: A Content Analysis of Bestselling Children's Books Anderson, Angela M 13 June 2011 (has links) The lack of sociological research on adult/child stratification in children’s books and the impacts books make in the lives of children and adults, especially in regards to socialization, are important reasons to investigate this medium. Through a conflict and feminist perspective, as well as utilizing a cultural diamond framework, this research examines the representations of power disparities between adults and children, and the structures of childrearing within the cultural object of 64 bestselling children’s picture books from 1993 to 2008. I employed content analysis to evaluate appearances of gender, age, race, parental behaviors, and childrearing structures. My findings demonstrate that gender and age disparities prevail, non-white main characters remain invisible, males as main adult characters exhibit higher rates of parental behaviors, and concerted cultivation child rearing structure is present in illustrations. Future research should focus on other aspects of the cultural diamond to gain deeper knowledge of cultural meanings.

Assim, generalizamos e unificamos todos os resultados precedentes deste tipo. Como aplicação, mostramos estimativas a priori para uma classe de problemas elípticos quasilineares com crescimento quadratico no gradiente e investigamos, sob várias hipóteses, a multiplicidade das soluções obtidas para este problema. / [en] This thesis focuses on global extension of the interior weak Harnack inequality for a general class of divergence-type elliptic equations, under very weak regularity assumptions on the differential operator. In this way we generalize and unify all previous results of this type. As an application, we prove a priori estimates for a class of quasilinear elliptic problems with quadratic growth on the gradient and we investigate, under various assumptions, the multiplicity of the solutions obtained for this problem.
