Massive amounts of data with a large number of predictors routinely arrive in data systems as a result of recent developments in data collection technology. In this data-intensive world, predictive models are more important than ever to extract information and make decisions, and are widely applied in many different fields....
Stroke is the leading cause of permanent adult disability. Subcortical unilateral (hemiparetic) stroke affecting the internal capsule or basal ganglia is the most common of all strokes and usually results in hemiparesis of the contralateral arm and leg. About 80% of the individuals with a moderate to severe hemiparetic stroke...
This dissertation investigates two ways in which personality psychology should move beyond the traditional approach of measuring personality with broad domains composed of trait descriptors, as exemplified by the Big Five taxonomy. The first study (Chapter 2) suggests an alternative to the traditional approach of aggregating personality items into domains....
Leptin, a peptide mainly secreted in proportion to adipose tissue mass, increases energy expenditure with a parallel increase in breathing. The existence of a leptin-mediated neural circuit linking breathing to metabolism has been speculated, yet the precise central mechanisms were unknown. In my thesis, I show that optogenetic activation of...
Thermoelectric materials are of particular interest in a variety of fields because of their ability to directly convert heat to electricity (and vice versa), however, they struggle to gain widespread adoption because of their low efficiency. A common strategy in the field of thermoelectricity is to introduce material defects into...
We consider the statistical study of partially observed queueing systems arising in application areas such as hospital networks, data centers and cloud computing systems. Since these services operate under strict performance requirements, a statistical understanding of their performance is of great practical interest. A key challenge in these settings is...
As humans have evolved over time, so have the materials that they rely on. From the Stone Age through the Iron Age, entire eras have been defined by specific materials, their corresponding properties, and the applications they have enabled. This is still true to this day, as the Silicon Age...
“Musical Networks in Bergamo and the Borders of the Venetian Republic, 1580–1630,” examines the mediation and circulation of northern Italian music through social and professional networks with an emphasis on Bergamo, a thriving musical center during this period. In so doing, I challenge established narratives of early modern history that...
This dissertation argues that the convergence of industrialized wage-labor, increased economic precariousness, close and partisan elections, and weak ballot laws dramatically increased the incidence of economic voter intimidation between 1873 and 1896. When this form of coercion primarily affected African American voters, as it did in the 1860s, politicians did...
This dissertation is a collection of three studies on topics in economic history and labor economics, in Italy and the United States. The chapters are ordered chronologically, based on the period of interest. In the first chapter, I investigate the causes and consequences of public spending on primary education in...
