- Description:
- Supported vanadium oxide materials have been extensively studied for alkane oxidative dehydrogenation (ODH) reactions due to their high activity and selectivity. The catalytic activity of supported VOx materials is influenced by the surface coverage of VOx sites and hence the distribution of V=O, V-O-V, and V-O-S (S, support) bonds. The...

- The question of how native species diversity affects a community’s ability to resist invasive species has inspired decades of research. One of the oldest invasion biology hypotheses is that more species rich ecosystems are less invaded. While there has been strong support for this hypothesis, there is also strong evidence...

- Description:
- Current prediction instruments for violent recidivism lack accuracy as recidivism rates for violent offenses remain high (Fazel & Wolf, 2015). Part of the issue may be the conceptualization of violent offenders as a homogenous group as opposed to heterogeneous subgroups. Additionally, various studies suggest that cognitive abilities in violent offenders...

- Description:
- Numerous insights into the sensorimotor systems that guide the control of voice have been garnered by observing how the system responds to manipulations of its auditory feedback. However, current approaches may be limited in the exploration of more complex parameters of volitional and adaptive voice control due to their limited...

- Description:
- Rationally assembled nanostructures exhibit distinct physical and chemical properties beyond their individual units. The development of nanofabrication tools enables precise structural defining of nanomaterials scalable to large areas. This dissertation focuses on plasmonic nanoparticle arrays that show unique diffractive coupling with lattice spacings engineered close to the wavelength of light....

- Since its discovery in 2012 at the Large Hadron Collider (LHC), efforts have beenmade to measure and characterize the properties of the Higgs boson. Among these efforts have been searches for rare decays of the Higgs predicted by the standard model (SM) of particle physics. One such decay is the...

- Description:
- The lanthanides, with their limited orbital effects and high oxophilicity, represent a class of catalytic metals highly distinguished from more commonly-utilized transition metals. Homogeneous lanthanide catalysts often afford high catalytic rates and impressive selectivity. However, challenges regarding the synthesis and utilization of highly air- and water-sensitive organo-lanthanide complexes have limited...

- Description:
- In this thesis, we study pushforwards of canonical and log-pluricanonical bundles on projective log canonical pairs over the complex numbers. We partially answer a Fujita-type conjecture proposed by Popa and Schnell in the log canonical setting. Built on Kawamata’s result for morphisms that are smooth outside a simple normal crossing...

Though this property makes cells versatile, it presents significant design challenges when, to treat diseases, we must alter cellular responses. To understand changes to the complex regulatory pathways that cause diseases, studies often investigate the...

- How do people make meaning of risk-taking? The present dissertation proposes a normative lay theory of risk-taking. The proposed model promotes the following core ideas: (a) Risk-taking is generally an ambiguous construct and requires the illumination of at least some dimensional parameters to disambiguate the risk behavior and risk-taker; (b)...

- In this dissertation I examine the entanglement between female literacy and female sexuality in nineteenth-century Brazilian novels. I investigate the ways in which male authors used literature as a mechanism for policing female sexuality and stabilizing the traditional family. I argue that nineteenth-century Brazilian fiction exhibits a recurring preoccupation with...
