Is What Works Working? Thinking Evaluatively About The What Works Clearinghouse, Andrew A. Nelson

Theses and Dissertations--Education Sciences

Since the mid-twentieth century, the U.S. Department of Education has drafted and enacted policies to bridge the research-practice gap—that is, the gap between “what works” according to educational research and what is actually practiced by teachers and their administrators (e.g., Dirkx, 2006; Joyce & Cartwright, 2019; Tseng, 2012). One of the latest manifestations of this “what works” political legacy is the What Works Clearinghouse (WWC), which took shape as part of the Institute of Education Sciences (IES) in 2002. The WWC’s mission is to be a “central and trusted source of scientific evidence for what works in education” (WWC, 2020d, …

Exploring Preservice Teachers’ Practices And Perspectives On Whiteness: Development And Initial Validation Of The Whiteness Components Scale, Falynn Amor Thompson

Theses and Dissertations--Educational, School, and Counseling Psychology

For decades, educational scholars have considered and investigated a number of factors (e.g., teacher beliefs and expectations, racism, and inadequate school resources) that maintain the negative schooling experiences of Black students. Recently, scholars have identified components of whiteness as factors informing the adverse educational experiences of these students. To date, however, few researchers have empirically examined attitudes, behaviors, and perspectives of whiteness in educational settings and among educational stakeholders. In addition, no study has explored an association between whiteness components and Black students’ overall educational experiences. The dearth of these studies in the educational and psychological literatures is due in …

A Study Of Language And Its Uses In Flute Performance And Pedagogy, Sarah Tuley

Theses and Dissertations--Music

Various tone colors can be produced on the flute in part by altering the shape of the lips, jaw and tongue movement, and air speed. As these actions are similar to those in the production of speech, flutists and flute teachers often associate aspects of playing with consonants and vowels. However, the shape of the oral cavity can vary depending on the spoken language of the flute-player. By becoming familiar with the pronunciations of different sounds from various languages, the flutist may discover a wider variety of tone colors at his/her disposal. This document will investigate the use of vowels …

Chimurenga Chepfungwa: A Liberated Cultural Curriculum For The Madzimbabwe Singer, Tanyaradzwa Tawengwa

Theses and Dissertations--Music

Chimurenga ChePfungwa is the self-liberation of the mind. Education can either be an instrument for liberation or a tool for colonial indoctrination, brainwashing, and enslavement — the European colonization of Africa in the late-nineteenth century and the continent's epic efforts at self-liberation have amply taught us this.

Chimurenga ChePfungwa calls for the centering of ChiVanhu knowledge systems such as Ngano, Tsumo neNziyo. ChiVanhu encapsulates Madzimbabwe indigenous knowledge systems, cosmologies, and ways of being, and this paper insists on the primacy of these ChiVanhu epistemologies for the construction of knowledge and knowing.

Amagama ayadala. Words create. So much of the language …

Songs For High Voice: An Annotated Guide To African Romances, Op. 17 By Samuel Coleridge-Taylor, Makeda Danielle Hampton

Theses and Dissertations--Music

African Romances, Op. 17, composed in 1897 by African-British composer Samuel Coleridge-Taylor (1875-1912), is a collection of seven songs for high voice that is uniquely both African and American. The lyrics of this song cycle were first published in the book Majors and Minors, a collection of poems published in 1895 by Paul Laurence Dunbar (1872-1906).

An analysis of resources supports that academic discourse in Black vocal music has been underrepresented due to the absence of centralized information, such as published scores, recorded materials, catalogs, and guides for study and performance. While in depth research focusing on the art …

Contemporary scholars have devoted much attention to the ways Keckley’s Behind the Scenes combines elements of multiple genres to assure its long-term survival …

Substrate Trafficking Within The Type Vii Secretion Systems Of Pathogenic Mycobacteria, Zachary A. Williamson

Theses and Dissertations--Molecular and Cellular Biochemistry

Tuberculosis (TB), primarily caused by infection of Mycobacterium tuberculosis (Mtb) in the lungs, is the deadliest infectious bacterial disease killing 1.5 million people annually. A major determinant of virulence is active secretion through three specialized type VII secretion (ESX) systems; ESX-1, ESX-3, and ESX-5. A large group of substrates exported by the ESX systems is the PE (Proline-Glutamine) and PPE (Proline-Proline-Glutamate) families of proteins, which are highly expanded in the pathogenic species of Mycobacteria and encompass over 7% of Mtb’s genome coding capacity. PE and PPE proteins interact together to form PE-PPE heterodimers, and are secreted through …

Reversible Glucan Phosphorylation In The Red Alga, Cyanidioschyzon Merolae, Corey Owen Brizzee

Theses and Dissertations--Molecular and Cellular Biochemistry

Starch and glycogen are an essential component for the majority of species and have been developed to maintain homeostasis in response to environmental changes. Water-soluble glycogen is an excellent source of quick, short-term energy in response to energy demands. In contrast, plants and algae have developed the macromolecule starch that is elegantly suitable for their dependence on external circumstances. Semi-crystalline starch is water-insoluble and inaccessible to most amylolytic enzymes, thus plants and algae have developed a coordinated system so that these enzymes can gain access to the denser starch energy cache. Starch-like semi-crystalline polysaccharides are also found in red algae, …

Characterization Of Spontaneous Preeclampsia In The African Green Monkey (Chlorocebus Aethiops Sabaeus), Chelsea Christina Weaver

Theses and Dissertations--Biology

Hypertensive pregnancy disorders are a major contribution to maternal and neonatal mortality worldwide. Two of these disorders, preeclampsia and chronic hypertension in pregnancy, affect up to 10% of all pregnancies. These hypertensive disorders of pregnancy are associated with long-term, postnatal risk factors for both mother and offspring. Despite numerous recent advances in preeclampsia research, the underlying mechanisms are still not understood. This could be due to lack of a spontaneous animal model. This dissertation presents the African Green Monkey (AGM; Chlorocebus aethiops sabaeus) as the first known spontaneous animal model of preeclampsia and a highly translational model of chronic …

The adoption of IoT features can also provide attackers with new potential avenues to access and exploit a system's vulnerabilities. Previously, existing systems could more or less be considered a closed system …

Combining Approximate Computing And Adiabatic Logic For Low-Power And Energy-Efficient Iot Edge Computing, Wu Yang

Theses and Dissertations--Electrical and Computer Engineering

The growing data-intensive applications that run on IoT edge devices require the circuit to be low-power consumption and energy-efficient for limited resources. As conventional Complementary Metal-Oxide-Semiconductor (CMOS) scales down to the nanometer technology node, it reaches its limits, such as leakage and power consumption. Adiabatic logic and approximate computing are emerging techniques for the low-power circuit. Adiabatic logic can recycle energy which is a promising solution for building energy-efficient circuits. However, the power clock scheme and dual-rail structure of adiabatic logic increase the overall area. Power consumption is further reduced by applying approximate computing while reducing the complexity and size …

Old cultivars had larger root systems with more roots that grew two times faster than intermediate/modern cultivars. Wild type …

Optimization Of Gelatin-Based Cellular Coating Of Msc For Myocardial Infarction Therapy, Kara Amelle Davis

Theses and Dissertations--Chemical and Materials Engineering

Cardiovascular disease remains the number one threat to American lives. During an acute myocardial infarction (AMI), blood flow is blocked and results in the formation of scar tissue. As the body’s immune system responds, inflammatory signaling causes an increase in both scar tissue size and the patient’s risk for further chronic heart failure. In order to reduce the risk of continued heart disease inflammatory signaling must be reduced. Stem cell therapies have the ability to alter the immune system’s pro-inflammatory signal. However, stem cell retention is limited due to blood flow shear. Gelatin methacrylate (GelMA) based coatings have been shown …
