Circadian rhythms — physiological, behavioral, and metabolic oscillations with an approximate 24-h period — are controlled by an evolutionarily conserved set of core clock genes operating at the transcriptional and protein level. Entrainable by Zeitgebers (external environmental stimuli such as light, temperature, and food) that modulate time-of-day specific functions, the...
Interfacial science brings together diverse areas of interest such as electronic materials, quantum materials, bio-membranes and catalysts. In-situ X-ray characterization techniques can be used to understand the assembly of atoms, molecules and supported nanoparticles at interfaces in complex environments. This thesis work focuses on the use of various X-ray characterization...
Having an Experience: Media Franchises, Events, & Participatory Culture explores, like its title suggests, what we mean when we talk about “having an experience” in today’s media culture. Traveling to an expanded network of sites where media fans are actively called to go out and “have an experience” in the...
While the proportion of students from lower socioeconomic status (SES) backgrounds enrolled in higher education continues to increase, rates of upward SES mobility among people from the
lower end of the socioeconomic distribution remain extremely low and socioeconomic inequality
in the United States continues to rise. The current manuscript examines...
The airway epithelial cells (AECs) lining the conducting passageways of the lung secrete a variety of immunomodulatory factors. One interesting pair of molecules produces by AECs is IL-6 and prostaglandin E2 (PGE2). PGE2 limits lung inflammation and promotes bronchodilation. By contrast, IL-6 drives intense airway inflammation, remodeling, and fibrosis. The...
While the scholarship on policing and surveillance suggests that police departments have and use a wide array of sophisticated tools, the literature has largely focused on only a handful of the largest departments. Moreover, these studies tend to be qualitative, so it is difficult to pinpoint what factors might be...
Triplet excited state chemistry has enabled a range of important organic transformations by accessing reaction pathways inaccessible to photoredox chemistry. Such photoreactions are triggered by triplet photosensitizers, which absorb visible-light photons and transfer the energy to the substrate or to a co-catalyst through triplet-triplet energy transfer (TT EnT). The most...
Graphene oxide (GO) is a heavily oxidized version of graphene, which is often made by oxidative chemical exfoliation from graphite powders. The reaction decorates the graphene sheets with oxygen-containing functional groups including hydroxyl and epoxide groups on the basal plane, as well as carboxyl groups on the edge, rendering the...
This dissertation studies the real effects of firms’ financing decisions as well as the economics consequences of bias in fair value prices of corporate bonds. The first chapter examines the impact of compliance with changes in mandated financial reporting on corporate financing and investment decisions. I employ the recent implementation...
The commitment of resources to coaching almost always occurs in interaction with other district-wide efforts to improve instruction. Given this probable situation, it’s concerning that the field lacks the ability to provide guidance regarding how coaches might reasonably be integrated within overall plans for the coordination and improvement of instruction....
