This dissertation offers a novel interpretation of Aristotle’s notion of teaching (didaskalia). In Part I, I defend my claim that we can find in Aristotle’s works a conception of teaching, which is a crucial yet under-explored part of his theory of education. In Part II, I use this interpretation to...
Light trapping with standing waves has been achieved using photonic bandgap crystals, metal-dielectric waveguides and periodic metal nanocavity arrays. Compared with photonic materials, plasmonic metal nanocavities can provide light confinement at the sub-wavelength scale with strong near-field electric enhancement. The localized surface plasmons of individual metal nanoparticles can collectively couple...
The social groups to which individuals belong, as well as the identities that result from these group memberships, exert powerful influences on their political attitudes. Additionally, political elites offer cues that shape these same preferences—often by targeting and interacting with identities. However, there remain underexplored pathways by which elites can...
Dynamic decision-making is a complex process that relies on our ability to generate, evaluate and implement a variety of strategies. Understanding how people navigate this process is a difficult problem that requires a wide range of methodologies. This study details a combination of behavioral experiments, computational modeling, and neuroimaging that...
The term compaction band identifies a rich variety of structural features of the Earth's crust that affect formations of sedimentary rocks. The most common definition for compaction band often found in the literature describes them as narrow planar zones of concentrated porosity reduction, which may involve limited to none shear...
As technology scales down, challenges in fabrication, thermal stress, and in-field degradation have put the reliability of processors at risk. Among different fault types, transient faults manifest themselves frequently due to high chip density, aggressive voltage scaling, and high clock frequency. Some dependable processor architectures have been proposed to counter...
This thesis investigates various aspects of productivity. In the first chapter I investigate the role of consumer demand in generating productivity dispersion. In particular, I study how differences in consumer preferences across the household income distribution generate dispersion in markups across the Indian manufacturing sector. I find that this consumer...
The high-temperature oxidation/reduction behaviors of iron and its oxides are important to a variety of energy conversion and storage technologies, such as the solid-oxide iron-air battery and chemical looping combustion. The useful lifetime of iron redox materials is limited, however, by structural degradation arising from (i) sintering, accelerated by phase...
Abstract Kaposi sarcoma (KS) is the most common cancer associated with human immunodeficiency virus/ Acquired Immunodeficiency Syndrome (HIV/AIDS) infection worldwide and it is the most prevalent cancer in some countries in sub-Saharan Africa (SSA). The introduction of combination antiretroviral therapy (ART), led to dramatic declines in KS morbidity and mortality,...
The effect of Alkali-Silica Reaction (ASR) on concrete mechanical behavior and the multi-physics considerations that come along are highly complex. Hydration and other chemical reactions occur at the micrometer scale. Hygro-thermal phenomena and concrete cracks due to ASR are typically studied at the meso-scale, i.e. at the aggregate level. At...
