Citizen media literacy is essential in a democratic society, particularly in the online environment where valid media sources have proliferated alongside purveyors of fake news. This dissertation explores technologies that automatically detect aspects of bias in news articles, with the ultimate aim of leveraging them to augment media literacy. It...
In the design of efficient adsorbents for the sequestration of toxic molecules and the separation of volatile organic compounds, two important criteria are: high porosity and high density of sorptive sites. The work in this thesis showcases how metal-organic frameworks (MOFs) can be used as porous adsorbent templates where many...
Quantum metrology has been among the most vigorous branches of quantum technology. It involves using quantum effects to achieve better estimation of parameters of a physical sys- tem. Conventionally the system consists of an ensemble of N non-interacting atoms and the measurements are done on individual atomic states, such as...
People and horses have a deep, co-constructed, and co-evolutionary history. This dissertation evaluates sociopolitical change of the Hungarian Bronze Age (2800 – 800 BC) in the context of long-term shifts in human-horse relationships. In the Bronze Age, horses are assumed to mount the development of complex polities ruled by elite,...
This dissertation studies topics in health care operations management related to value-based care, where {\em value} can be thought of as the ratio of quality to cost. The objective in value-based care is to increase, or maximize, value by reducing costs and improving quality health outcomes. In Chapter 1 we...
This dissertation is a broad study on individual and firm-level financial conditions and their effects on politics. In the first chapter, I study the effect of economic conditions on political polarization using micro-data on house prices, mortgages, and individual political contributions. I argue that shocks to housing wealth --- the...
The world is an increasingly interdependent place. Regions of economic activity are deeply connected with each other through the movement of goods, labor and ideas. This has deep consequence for both the economist and policymaker: in the evaluation of economic activity, an exogenous shock in any given region does not...
Macrophages are one of the most versatile immune cells in the immune system. They are found in nearly every tissue and organ throughout the body. Macrophages play important roles of orchestrating initiation and resolution of inflammation, such as sentineling against pathogens or engulfing apoptotic cells. Macrophages are able to respond...
In December 1889, a few weeks after the monarchy in Brazil was replaced by a republican government, seventy-year-old USAmerican poet Walt Whitman wrote a poem called “A Christmas Greeting” to welcome the “Brazilian brother” into democracy. Though filled with hope and excitement for yet another republic born in the Americas,...
Proteins are a class of nanoscale building block with remarkable chemical complexity and sophistication: their diverse functions, shapes and symmetry, and atomically monodisperse structures far surpass the range of nanoparticles that can be accessed synthetically. The chemical topology of proteins that drive their assembly into higher order materials are central...
