A Visual Political World: Determinants And Effects Of Visual Content, Silvia Michelle Torres Pacheco
A Visual Political World: Determinants And Effects Of Visual Content, Silvia Michelle Torres Pacheco
Arts & Sciences Electronic Theses and Dissertations
Political communication is a central element of several political dynamics. Its visual component is crucial in understanding the origin, characteristics and consequences of the messages sent between political figures, media and citizens. However, visual features have been largely overlooked in Political Science. Thus, in this dissertation, I introduce, describe and apply computer vision techniques for the analysis and processing of visual material, in order to not only improve data collection and visual content extraction, but also the understanding of the effects that visual components have on relevant political variables. In the first main chapter of this project, I implement computer …
Essays On Econometrics And Rational Choice, Junnan He
Essays On Econometrics And Rational Choice, Junnan He
Arts & Sciences Electronic Theses and Dissertations
Decision and choice theory is a topic of interest in both econometrics and microeconomic theory. We contribute to the theory of decision under both contexts, that is, the theory of model selection in econometrics, and the theory of rational decision in microeconomics.
There is a long-lasting theoretical interest in model selection. More recently, research on sparse estimators, a class of estimation methods that select and estimate important parameters simultaneously, has been the central focus on model selection. The methods become especially relevant when the problem is of high-dimensional nature. Theoretically, sparse methods can perform well when the true data generating …
Mechanics Of Phenotypic Aging Trajectories In C. Elegans And Humans, William Zhang
Mechanics Of Phenotypic Aging Trajectories In C. Elegans And Humans, William Zhang
Arts & Sciences Electronic Theses and Dissertations
Overall, my dissertation integrates longitudinal measurements of physiology to investigate the aging process. In the first half, I examine the surprising and largely unexplained degree of variation in lifespan within even homogeneous populations. I sought to understand how physiological aging differs between long- and short-lived individuals within a population of genetically identical C. elegans reared in a homogeneous environment. Using a novel culture apparatus, I longitudinally monitored aspects of aging physiology across a large population of isolated individuals. Aggregating several measures into an overall estimate of senescence, I find that long- and short-lived individuals start adulthood on an equal physiological …

Wish You Were Here, Janie Stamm, Janie I. Stamm
Graduate School of Art Theses
The State of Florida is under threat from the effects of climate change. Rising sea levels are creeping up on to Florida’s coast, eroding the beaches and encroaching on heavily populated cities. Over my lifetime I will watch the water spill over the streets of my home town. I will watch the water flood the Everglades, pushing saltwater into freshwater habitats. I will watch the water begin to drown the state, taking Florida’s many little known histories along with it. This thesis serves as a document of Floridian life during the Anthropocene.
Within this thesis, I tell the story of …
