Social studies teachers represent various political, racial, and ideological perspectives. It remains unclear how social studies teachers choose curricula and balance the racial representation they present and the implications for students' racial lenses and understanding of race in the past and present. This qualitative study will have an impact…

The murder of George Floyd and COVID-19 in 2020 catapulted the issues of diversity, equity, and inclusion (DEI) to the forefront in every aspect of life: housing, healthcare, Internet access, and education. The perception of university leadership's actions and their ability to make appropriate decisions regarding those issues in creating a campus…

This dissertation presents results from research and curriculum development related to student understanding of the principle of superposition in introductory optics and upper-division quantum mechanics courses. The focus is on the extent to which students are able to relate the mathematical formalism used in physics to real-world phenomena. In…

Advances in electronics technology have transformed the cockpits of large and small modern aircraft. This transformation has created new challenges for the aviation electronics industry and the technicians that support and maintain aircraft. To meet these challenges, it is important to know the knowledge skills, and abilities required by these new…

Childhood permanent, uncorrectable vision impairment (VI) is rare, yet it is a public health burden as the impairment lasts a lifetime. Vision impairment describes decreased vision that affects everyday activities. Acuity cut-points commonly used include 20/40, 20/60 or 20/70. Blindness often refers to legal blindness (best corrected visual acuity…

Relatively little empirical attention has been paid to the political economy of publicly-retailed fiber-optic broadband internet service. To address this gap in the literature, this dissertation examines the history, dynamics and trends in the municipal broadband movement. In specific, Wilson, North Carolina's Greenlight service is examined in…

This discourse analysis study examines the final moments of selected online sermons delivered by America's leading evangelical pastors and speakers, paying particular attention to the language employed in the presentation of Christian gospel tenets, the public invitation for salvation, the altar call that identifies new followers, and the…

In order to truly meet the unique learning needs of young children with blindness and visual impairment (BVI), it is critical to accurately define the population to create and implement quality and responsive support services. The current analysis utilized existing data gathered from the Babies Count database to examine the defining…

This dissertation is composed of two parts. In the first part techniques of band exclusion(BE) and local optimization(LO) are proposed to solve linear continuum inverse problems independently of the grid spacing. The second part is devoted to the Fourier phase retrieval problem. Many situations in optics, medical imaging and signal processing call…

Developments in analytical chemistry were made using acoustically levitated small volumes of liquid to study enzyme reaction kinetics and by detecting volatile organic compounds in the gas phase using single-walled carbon nanotubes. Experience gained in engineering, electronics, automation, and software development from the design and…

The purpose of this study was to explore upper elementary reading classes in a low socio-economic area to determine the effects frequent praise, both academically and socially, have on the zone of proximal development in reading (ZPD[subscript RL], Renaissance Learning, 2006). A causal-comparative study was utilized by observing two groups of…

It has been more than two decades since the copper-oxide high temperature superconductors were discovered. However, building a satisfactory theoretical framework to study these compounds still remains one of the major challenges in condensed matter physics. In addition to the mechanism of superconductivity, understanding the properties of the…

Intercellular signaling is vital to communication within neuronal circuits. The suprachiasmatic nucleus (SCN), the master circadian clock of mammals, contains a dense collection of neurons that align their intrinsic rhythmicity with environmental stimulus and physiological state. While peptide physiology has been demonstrated as a contributor to…

The objective of this dissertation is to explore the socio-cultural contextualization of the digital divide in Japanese society. I undertake this task by developing a theoretical and methodological framework based on the notion of "culture as models," while explicating the cultural dimensions of the digital divide and the dynamics of…

In addition to the display application, Liquid Crystals (LC) can be very useful in other applications such as beam steering, tunable lenses, etc. Electro-optical LC tunable lenses have been considered as an alternative to conventional glass lenses because of their ability to change their focal length with the application of a control voltage, as…
