With organizations’ rising interest in creativity as one of the most sought out skill sets for graduates, it has become crucial to infuse creativity training in academic programs. This study evaluated freshmen business students’ perceptions about their personal, everyday creativity and examined the influence of infusing creativity training in their freshmen seminar course. This action research study drew upon the intersection of three creative self-belief theories from management and education psychology literature: Jaussi, et al (2007) Creative Identity Theory; Karwowski (2014) Creative Mindset Theory; and Tierney & Farmer (2002) Creative Self-efficacy Theory. These theories arguably stemmed from Burke (1991) Identity …

The commercial semiconductor industry is gearing up for 5G communications in the 28GHz and higher band. In order to maintain the same relative receiver sensitivity, a larger number of antenna elements are required; the larger number of antenna elements is, in turn, driving semiconductor development. The purpose of this paper is to introduce a new method of dividing wireless communication protocols (such as the 802.11a/b/g/n and cellular UMTS MAC protocols) across multiple unreliable communication links using a new link layer communication model in concert with a smart antenna aperture design referred to as Vector Antenna. A vector antenna is a …

Glycosaminoglycans (GAGs) are long chains of negatively charged sulfated polysaccharides. They are often found to be covalently attached to proteins and form proteoglycans in the extracellular matrix (ECM). Many proteins bind GAGs through electrostatic interactions. GAG-binding proteins (GBPs) are involved in diverse physiological activities ranging from bacterial infections to cell-cell/cell-ECM contacts. This thesis is devoted to understanding how interactions between GBPs and their receptors modulate biological phenomena. Bacteria express GBPs on surface that facilitate dissemination and colonization by attaching to host ECM. The first GBP investigated in this thesis is decorin binding protein (DBP) found on the surface of Borrelia …

Rotary drums are commonly used for their high heat and mass transfer rates in the manufacture of cement, pharmaceuticals, food, and other particulate products. These processes are difficult to model because the particulate behavior is governed by the process conditions such as particle size, particle size distribution, shape, composition, and operating parameters, such as fill level and rotation rate. More research on heat transfer in rotary drums will increase operating efficiency, leading to significant energy savings on a global scale. This research utilizes infrared imaging to investigate the effects of fill level and rotation rate on the particle bed hydrodynamics …

My thesis argues that an unrecognized genre existed in classical Chinese painting, one which I call “ethnic" or "minority painting.” The genre of ethnic painting consistently displays certain styles and cultural values and is meant to represent unique ethnic identities. These ideas have not been substantially covered by previous research on Qing dynasty painting. My research raises three main questions: was there a distinct genre in traditional Chinese painting that could be called “ethnic art” (or "minority art")? How did ethnic art distinguish itself within Chinese painting? What were the ethnic identities presented by minority artists from ethnic groups within …

Human endeavors move 7x more volume of earth than the world’s rivers accelerating the removal of Earth’s soil surface. Measuring anthropogenic acceleration of soil erosion requires knowledge of natural rates through the study of 10Be, but same-watershed comparisons between anthropogenically-accelerated and natural erosion rates do not exist for urbanizing watersheds. Here I show that urban sprawl from 1989 to 2013 accelerated soil erosion between 1.3x and 15x above natural rates for different urbanizing watersheds in the metropolitan Phoenix region, Sonoran Desert, USA, and that statistical modeling a century of urban sprawl indicates an acceleration of only 2.7x for the Phoenix …

This work explores the underlying dynamics of democracies in the context of underdevelopment, arguing that when society has not attained a substantial degree of economic independence from the state, it undermines democratic quality and stability. Economic underdevelopment and political oppression are mutually reinforcing, and both are rooted in the structure of the agriculture sector, the distribution of land, and the rural societies that emerge around this order. These systems produce persistent power imbalances that militate toward their continuance, encourage dependency, and foster the development of neopatrimonialism and corruption in the government, thereby weakening key pillars of democracy such as accountability …

There is an ever-increasing demand for higher bandwidth and data rate ensuing from exploding number of radio frequency integrated systems and devices. As stated in the Shannon-Hartley theorem, the maximum achievable data rate of a communication channel is linearly proportional to the system bandwidth. This is the main driving force behind pushing wireless systems towards millimeter-wave frequency range, where larger bandwidth is available at a higher carrier frequency. Observing the Moor’s law, highly scaled complementary metal–oxide–semiconductor (CMOS) technologies provide fast transistors with a high unity power gain frequency which enables operating at millimeter-wave frequency range. CMOS is the compelling choice …

One type of assistive device for the blind has attempted to convert visual information into information that can be perceived through another sense, such as touch or hearing. A vibrotactile haptic display assistive device consists of an array of vibrating elements placed against the skin, allowing the blind individual to receive visual information through touch. However, these approaches have two significant technical challenges: large vibration element size and the number of microcontroller pins required for vibration control, both causing excessively low resolution of the device. Here, I propose and investigate a type of high-resolution vibrotactile haptic display which overcomes these …

Quiescin sulfhydryl oxidase 1 (QSOX1) is an enzyme that catalyzes disulfide bond formation by oxidizing two free sulfhydryl groups. QSOX1 consists of a thioredoxin (Trx) and an ERV (essential for respiration and viability)/ALR (augmenter of liver regeneration) domain which each contain CxxC motifs that work to bind to substrates and shuttle electrons to a flavin adenine dinucleotide (FAD) cofactor that accepts the electrons and reduces molecular oxygen to hydrogen peroxide. Investigation of the role of QSOX1 in cancer progression started when it was found at higher abundance in pancreatic ductal adenocarcinoma (PDA) patient plasma compared to healthy normal donor plasma. …

The dynamics of a fluid flow inside 2D square and 3D cubic cavities under various configurations were simulated and analyzed using a spectral code I developed. This code was validated against known studies in the 3D lid-driven cavity. It was then used to explore the various dynamical behaviors close to the onset of instability of the steady-state flow, and explain in the process the mechanism underlying an intermittent bursting previously observed. A fairly complete bifurcation picture emerged, using a combination of computational tools such as selective frequency damping, edge-state tracking and subspace restriction.

Recognizing that CEOs are less capable of diversifying their employment risks than shareholders who could diversify their investment risks through portfolio investments, agency theory assumes that CEOs tend to be risk averse compared with shareholders. Based on this assumption, agency theory scholars suggest that to align the risk preference of CEOs with that of shareholders, CEOs need to be closely monitored and have less power. SEC regulators have been adopting the suggestion and accordingly CEO power has been reduced in the past decades. However, the empirical results are mixed and cannot provide solid support for the suggestion that reducing CEO …

Valley Fever (VF), is a potentially lethal fungal pneumonia caused by Coccidioides spp., which is estimated to cause ~15-30% of all community-acquired pneumonias in the highly endemic Greater Phoenix and Tucson areas of Arizona. However, an accurate antigen-based diagnostic is still lacking. In order to identify protein and glycan antigen biomarkers of infection, I used a combination of genomics, proteomics and glycomics analyses to provide evidence of genus-specific proteins and glycosylations. The next goal was to determine if Coccidioides-specific glycans were present in biological samples from VF patients. Urine collected from 77 humans and 63 dogs were enriched for glycans …

During the Nazi era, which is historically regarded as lasting from 1933-1945, the National Socialists both looted and made “legal” confiscations of art and artifacts they deemed “degenerate” from museums throughout occupied Europe. The art they seized was sold abroad in exchange for foreign currency that not only funded their war efforts, but also allowed for purchases of art for Hitler’s un-realized Führermuseum in Linz, Austria. The rapid transfer of objects flooded the art market, making this period one of the most prosperous times for collectors and dealers. However, due to the overall hasty nature of the displacements, the ownership …

For a conventional quadcopter system with 4 planar rotors, flight times vary between 10 to 20 minutes depending on the weight of the quadcopter and the size of the battery used. In order to increase the flight time, either the weight of the quadcopter should be reduced or the battery size should be increased. Another way is to increase the efficiency of the propellers. Previous research shows that ducting a propeller can cause an increase of up to 94 % in the thrust produced by the rotor-duct system.

This dissertation investigates the precise degree to which prosody and syntax are related. One possibility is that the syntax-prosody mapping is one-to-one (“isomorphic”) at an underlying level (Chomsky & Halle 1968, Selkirk 1996, 2011, Ito & Mester 2009). This predicts that prosodic units should preferably match up with syntactic units. It is also possible that the mapping between these systems is entirely non-isomorphic, with prosody being influenced by factors from language perception and production (Wheeldon & Lahiri 1997, Lahiri & Plank 2010). In this work, I argue that both perspectives are needed in order to address the full range of …

It further analyzes the gaps in sustainability discourse that can be filled by environmental justice, such as the challenges posed by environmental racism. Despite this, neither field is able to contend with IEV in a meaningful way, which this thesis argues using the case study of the Flint Water Crisis (FWC). The FWC has …

Seeking an upper limit of the Neutron Electric Dipole Moment (nEDM) is a test of charge-parity (CP) violation beyond the Standard Model. The present experimentally tested nEDM upper limit is 3x10^(26) e cm. An experiment to be performed at the Oak Ridge National Lab Spallation Neutron Source (SNS) facility seeks to reach the 3x10^(28) e cm limit. The experiment is designed to probe for a dependence of the neutron's Larmor precession frequency on an applied electric eld. The experiment will use polarized helium-3 (3He) as a comagnetometer, polarization analyzer, and detector. Systematic influences on the nEDM measurement investigated in this …

Biculturalism embodies the degree to which individuals adapt to living within two cultural systems and develop the ability to live effectively across those two cultures. It represents, therefore, a normative developmental task among members of immigrant and ethnic-racial minority groups, and has important implications for psychosocial adjustment. Despite a strong theoretical focus on contextual influences in biculturalism scholarship, the ways in which proximal contexts shape its development are understudied. In my dissertation, I examine the mechanisms via which the family context might influence the development of bicultural competence among a socio-economically diverse sample of 749 U.S. Mexican-origin youths (30% Mexico-born) …

In my thesis, I characterize multi-nuclear manganese cofactors in modified reaction centers from the bacterium Rhodobacter sphaeroides. I characterized interactions between a variety of secondary electron donors and modified reaction centers. In Chapter 1, I provide the research aims, background, and a summary of the chapters in my thesis. In Chapter 2 and Chapter 3, I present my work with artificial four-helix bundles as secondary electron donors to modified bacterial reaction centers. In Chapter 2, I characterize the binding and energetics of the P1 Mn-protein, as a secondary electron donor to modified reaction centers. In Chapter 3, I present the …
