Several semiparametric estimators recently developed in the econometrics literature are based on the rank correlation between the dependent and explanatory variables. Examples include the maximum rank correlation estimator (MRC) of Han (1987), the monotone rank estimator (MR) of Cavanagh and Sherman (1998), the pairwise-difference rank estimators (PDR) of Abrevaya (2003),...

Assembly of the large and small subunits of the <em>E. coli</em> ribosome is a complicated process that involves transcription, processing, and modifying of the ribosomal RNA, the binding of ribosomal proteins, and the folding of the particles into complex structures. A number of ribosome assembly factors, including maturation factors, GTPases,...
The expansion of public education at the beginning of the twentieth century had a profound effect on the American economy. This dissertation explores the impact of changing educational institutions on both individuals and communities with a study of Iowa during its introduction of modern grammar schools and high schools during...
For all its significance in world affairs, the United Nations is full of paradoxes. As a system - i.e. as a collection of independent yet interrelated entities - its contradictions derive from the juxtaposition of forces encouraging fragmentation and calls for improved harmonization. On its part, the reality of inter-organizational...
The promise of a clean, renewable, and abundant energy supply make the efficient conversion of solar energy to electricity a compelling scientific and societal goal. In the following chapters, I will describe my efforts to advance one class of photovoltaic technology, dye-sensitized solar cells, by demonstration and characterization of unexplored...
Polarized epithelial cells are divided by tight junctions into an apical membrane domain, which faces the lumen of an organ, and a basolateral domain, which is in contact with underlying connective tissues. To establish and maintain polarity, newly synthesized and recycling transmembrane proteins are sorted to either the apical or...
Breakout reactions from the CNO cycles leading into the rp-process in explosive stellar hydrogen burning environments have been studied using the Argonne Tandem Linac Accelerator System (ATLAS). Earlier work is reported and summarized with an introduction to the beam, target and detector development in the nuclear astrophysics group at Argonne...
This dissertation consists of three self-standing essays, each of which focuses on a dialogue from Plato's later period. Together, they touch on some of his well-known views in metaphysics and moral psychology, from his theory of forms to his theory of the tripartite soul. But the topic that unifies these...
The goal of this dissertation was to elucidate the coalescence of vacancies in the cubic polytype of silicon carbide in a nuclear reactor relevant system. Large-scale empirical potential atomistic simulations were employed and the exploration of long time-scale behavior was performed through a new application of the parallel replica dynamics...
