The marginalization index for each municipality in Mexico confirms that the country is characterized by substantial economic inequality. Using this index as a tool to measure inequality in urbanization and data from the Consejo Nacional de Población (CONAPO) and the Instituto Nacional de Estadística y Geografía (INEGI), this work first analyzes observed spatial patterns of the marginalization index. Next, this dissertation analyzes the association between marginalization and mortality patterns inside Mexico. Overall, there is evidence of high marginalization linked to high mortality rates. Factors that might influence marginalization like geographical differences do not seem to influence the relationship between marginalization and mortality. Factors like migration and indigenous population percentages show more relevance in explaining the association between marginalization and mortality as a social causation effect. / text

Diatom-diazotroph associations contribute extensively to vertical flux in the modern ocean, and are linked to extensive sedimentary layers in the paleo-record formed either by rapidly sinking aggregates or more slowly sinking cells and chains. Although diatom sinking rates have been extensively studied, the sinking rates of these diatom symbioses are poorly documented. The effect of silicate and phosphate limitation on the sinking rate of Hemiaulus hauckii and its symbiont Richelia intracellularis were determined in semi-continuous cultures using a SETCOL. TEP (transparent exopolymer particle) was measured concurrently for linkages to aggregate formation. Although cells occurred in chains of 1-20 cells long, aggregate formation did not occur in semi-continuous cultures. There was no significant effect of P or Si limitation on sinking rates compared to controls. Although H. hauckii possess a symbiont that lacks gas vesicles, sinking rates (0.04-0.72 m/day) were within the range predicted by size-rate relationships. A portion of each H. hauckii experimental measurement ascended as well with significant differences found between the lowered P 80% exchange and the lowered Si with 80% exchange (p=0.05) and between the lowered Si with 80% exchange and the Si control batch culture (p=0.039). TEP production did not change significantly between treatments. However, a fraction of TEP in each population was positively buoyant as well, with ascent rates between 0.32-0.49 m/day. This study confirms an earlier report of positive buoyancy in TEP as well as noting that a significant fraction of the Hemiaulus symbiosis can be ascending within the population. / text
