Understanding how spin waves propagate through ferromagnets is an important component of a wider international effort to create spintronic devices. In this thesis, we develop a propagating spin wave spectroscopy to make a variety of measurements on thin films of Yttrium Iron Garnet (YIG), a material known for having long...
When a cell divides, it must assemble a microtubule-based structure called a spindle, which provides the forces that physically segregate the chromosomes. In most cell types the microtubules that comprise the spindle are nucleated and organized by centriole-containing centrosomes. In many species, however, oocyte meiosis is carried out in the...
This dissertation reports on a 16-week ethnographic study of politicized caring within a museum-based tinkering program for high school students called the FabYouth program. Drawing on a data set that includes 16 field notes, 785.83 minutes (about 13.1 hours) of ethnographic audio-video recordings, 280 photographs, and ten student interviews, I...
A great deal of work has been done in recent years to construct algebraic invariants ofLegendrian knots, and their higher-dimensional analogues. Here we employ the diagram-
matic calculus developed in [3], in order to develop an iterative method for computing the
so-called vexillary functions of a class of Legendrian surfaces....
This dissertation consists of three chapters that each study the interaction between government policy and real estate markets. All three chapters are connected by a broad interest in renters, landlords, and rental markets. Chapter 1 investigates the relationship between place-based policies and real estate and rental markets empirically by studying...
Ataxic dysarthria is a disorder affecting the naturalness of speech due to damage to the cerebellum, a neural structure critical for the timing, scaling, and sequencing of speech movements (Ackermann, Vogel, Petersen, & Poremba, 1992; Diener & Dichgans, 1992; Duffy, 2013; Rampello, Rampello, Patti, & Zappia, 2016). In healthy individuals,...
Problems in interpersonal functioning are a major concern. In adults, interpersonal dysfunction is often investigated as it relates to personality disorders (PDs). In fact, researchers have argued that a core of interpersonal dysfunction is what defines personality disorders (Hopwood, Wright, Ansell, & Pincus, 2013). This is perhaps most evident for...
The Escherichia coli ribosome is a molecular machine capable of sequence-defined polymerization of -amino acids into proteins, a feat unmatched by any other current synthetic catalyst. It is complex in its structure, comprised of 3 RNA parts (the 5S, 16S, and 23S ribosomal RNAs) and 54 ribosomal proteins (r-proteins). Efforts...
This dissertation addresses problems in the source properties of major earthquakes. It is composed of four largely independent studies. In chapter 2, we explore the possible theoretical origin of the distance-depth correction q(, h) introduced 75 years ago by B. Gutenberg for the computation of the body wave magnitude mb,...
Standard-based accountability policies have profoundly shaped the landscape of public education in the United States. At the heart of these policies are standardized assessments, administered annually, which are used to evaluate schools and, at times, teachers. While always controversial, opposition to these policies increased following the widespread adoption of the...
