Citizenship in the United States: The Roles of Immigrant Characteristics and Country of Origin This study develops and estimates a model of the naturalization process in the US. The model is based on both the characteristics of immigrants and features of their countries of origin. The empirical analysis is based on the 2000 US Census. Both the characteristics of immigrants and the origin-countr...

many species of the freshwater pulmonate snail family lymnaeidae act as intermediate hosts in the transmission of digenean trematode larvae, including those of the causative agent of fasciolosis. based on this, current investigation was aimed to determine diversity and geographical distribution of lymnaeidae snails and role of biochemical indices in habitat of them in west azerbaijan province, ...

Abstract: In geographical epidemiology, disease counts are typically available in discrete spatial units and at discrete time-points. For example, surveillance data on infectious diseases usually consists of weekly counts of new infections in pre-defined geographical areas. Similarly, but on a different timescale, cancer registries typically report yearly incidence or mortality counts in admini...

OBJECTIVES This study examined trends in geographical disparities in cardiovascular-disease (CVD) mortality in the United States between 1969 and 2011. METHODS National vital statistics data and the National Longitudinal Mortality Study were used to estimate regional, state, and county-level disparities in CVD mortality over time. Log-linear, weighted least squares, and Cox regression were us...

In this paper we present an algorithm, which vectorize geographical images. The transformation from a raster representation to a vectorial one is a question that has to be frequently treated in the management and processing images. For example the geographical information is readily available on photos, maps, planimetries. These documents contain characters, symbols and graphical parts. Usually...

Although topic models designed for textual collections annotated with geographical meta-data have been previously shown to be effective at capturing vocabulary preferences of people living in different geographical regions, little is known about their utility for information retrieval in general or microblog retrieval in particular. In this work, we propose simple and scalable geographical late...
