The Aftermath Of The Black Death In England: Edward Iii's Economic Policies To Repress The Peasantry, Leah Diciesare

Undergraduate Theses, Capstones, and Recitals

The Black Death caused a mass mortality in England, drastically affecting society. However, it was the aftermath of the plague that had the greatest impacts. The loss of life removed pressure on the economy due to population density, which gave the peasants opportunities to improve their lives. But that was a short-lived phenomenon; the peasantry ultimately remained repressed, as they had been prior to the plague. Edward III meddled in the English economy in the wake of the Black Death by introducing price and wage regulations. These efforts were to maintain the status quo in English society so that the …

Do You Hear Us? Amplifying Alternative Pathways For High School Pushouts Through Youth Participatory Action Research, Rob A. Duren

Educational Leadership and Policy Studies: Doctoral Research Projects

The school-to-prison pipeline (STPP) metaphor encapsulates and describes a set of legislative policies and educational practices that systematically funnel African American, Indigenous, and Latinx students from the classroom into the juvenile and criminal justice system at disparate rates. An emerging solution to address high school pushout and the STPP has been to develop Alternative Education Campuses (AECs). However, there is a current gap in the research that amplifies the counter narratives of students currently enrolled at an AEC, through their own words, using Youth Participatory Action Research (YPAR). Studies conducted with students who have been labeled “high-risk” are especially lacking. …

Automated Change Detection In Privacy Policies, Andrick Adhikari

Electronic Theses and Dissertations

Privacy policies notify Internet users about the privacy practices of websites, mobile apps, and other products and services. However, users rarely read them and struggle to understand their contents. Also, the entities that provide these policies are sometimes unmotivated to make them comprehensible. Due to the complicated nature of these documents, it gets even harder for users to understand and take note of any changes of interest or concern when these policies are changed or revised.

With recent development of machine learning and natural language processing, tools that can automatically annotate sentences of policies have been developed. These annotations can …

Thermally Driven Spin Transport In Ferromagnetic Metals, Wafa Saud Aljuaid

Electronic Theses and Dissertations

Since the discovery in 2008, the spin Seebeck effect has become one of the most active topics in the spin caloritronics research field. It opened a new way to create spin current by a combination of magnetic fields and heat. A temperature gradient in ferromagnetic (FM) metals generates a ow of spin current due to split of spin chemical potential between spin up and spin down electrons. This thermal spin current has been detected using an attached nonmagnetic heavy metal with large spin Hall angle via the inverse spin hall effect (ISHE). A voltage signal is generated since the nonmagnetic …

Experimental Investigation Of Low-Voltage Silicon Carbide (Sic) Semiconductor Devices For Power Conversion Applications, Saleh Salem H. Alharbi

Measuring The Connective Action Of Black Lives Matter Activists: A Psychometric Investigation Into Twitter Data, Paige Alfonzo

Electronic Theses and Dissertations

Many protest movements from the last twenty-first century have become increasingly networked and personalized. Several scholars have tapped into this change coining terms such as participatory action, digitally mediated action, computer-mediated communication, issue-based organization, and what I focus on in this project, connective action. Building on the ideas percolating across the literary landscape at the time, Bennett and Segerberg (2012) introduced the logic of connective action based on emergent characteristics they observed in post-2010 large-scale social movements. Both the logic of connective action and related work have become deeply ingrained in today's social movement scholarship. As such, I felt it …

Examining Artifacts Of The Watershed Segmentation, Emily Jo Armitage

Electronic Theses and Dissertations

The watershed segmentation is an algorithm used to systematically track cell intercalary behaviors during germ band extension of the Drosophila embryo. Neighboring cells share a contracting vertical interface, called a T1, which continues contracting to a single point, a T2, and extending in the horizontal direction to create what is called a T3 interface (Fig. 1). Additionally, higher order vertices called rosettes occur when five or more cells meet at a common vertex. Simulated T2 events demonstrate that cell angle and not noise level in the image contributes to the incorrect detection of artifactual T1s in more acute angled cells …

Social Work, Social Justice, And The Causes To Which We Are Called: Attitudes, Ally Behavior, And Activism, Brittanie Atteberry Ash

Electronic Theses and Dissertations

As a profession, social work has codified within its ethical guidance and educational policies a commitment to social justice. While social justice is enumerated in several guiding documents, social work continues to lack consensus on both the meaning and merit of social justice (Abramovitz, 1993; Funge, 2011; Hong & Hodge, 2009; Specht & Courtney, 1995; Van Soest & Garcia, 2003). Due to the lack of agreement within the profession about the centrality and meaning of social justice, many educational practices, attitudes, and actions of those working within the profession may not align with socially just ideals that are codified in …

The Emerging Metamodern Sensibility In Narrative: A Case Study Of Things Left Forgotten And The Dai Gyakuten Saiban Games, Gina Barbieri

Electronic Theses and Dissertations

This thesis proposes a metamodern shift in recent narrative trends, which incorporate modernist and postmodernist techniques for narrative. This includes narrative shifts which utilize postmodern devices such as irony and satire for seemingly modern ends such as hope and progress. This thesis posits that this shift can be understood through an analysis of emergent media, and considers the intertextual nature of fanfiction narratives emerging from games through a case study of Things Left Forgotten, a fanfiction written by Archive of Our Own user LookerDeWitt and based upon the two Dai Gyakuten Saiban games, spinoffs of the Ace Attorney series …

Fluid Dynamics Characterization Of Transcatheter Aortic Valves, Mohammed Barakat

Electronic Theses and Dissertations

Aortic stenosis due to degenerative calcific aortic valvular disease is the most reason for aortic valve replacement in developed countries. Aortic stenosis affects up to 7% of the world population, and current clinical data indicate that the number of the affected people could be triple by 2050, due to population ageing and health lifestyle. Transcatheter aortic valve replacement (TAVR) was introduced as a minimal invasive treatment of severe aortic stenosis. Even though surgical aortic valve replacement (SAVR) is considered the golden standard treatment for severe aortic stenosis patients, TAVR showed equivalent or even superior outcome compare to SAVR. Currently, transcatheter …

They are commonly used in the study of climatic changes throughout the Holocene and the reconstruction of neoglacial chronologies. For this research, Schmidt hammer rebound values, weathering rind thicknesses, and the length of lichen thalli diameters found on rock glacier surfaces are used to investigate their effectiveness as field-based relative age determination techniques. Additionally, the ability to identify periods of neoglacial activity using these methods is assessed in two neighboring cirque basins in the San Juan Mountains of Colorado. 41 field sites across three rock glaciers are established with …

Impacted Youth: Why School Psychologists Need To Consider Diverse Approaches Of Support, L. Morgan Beidleman

Electronic Theses and Dissertations

This paper examines trends among youth who are highly impacted by multiple adverse experiences. It outlines potential patterns of risk and protective factors often experienced by this population and encourages school psychologists to recognize, consider, and advocate for the needs of these youth. It goes on to describe and interpret the cultural practices of Leadership Coffeehouse, a Denver-based social enterprise that seeks to support disconnected youth through professional development and hands-on learning. Finally, because of the unique training school psychologists receive, considerations for expanding the role into non-traditional educational settings are proposed.

People And Place: A Journey Through Film, Tourism, And Heritage, Sarah Beals

Electronic Theses and Dissertations

Old Tucson Studios is a theme park where film, tourism, and heritage all converge through the American Western genre. During national social change, Westerns increase in number to reflect national values and identity. Westerns that ally with landscapes and people are potentially the most powerful storytelling tool in mainstream media. My research shows that this paring of people and place creates a prevailing image in the audience’s memory. The results suggest that the current image of the West comes from films made between 1951-1970, despite there being newer Westerns. John Wayne and saguaro cactus are enduring images with historic, cultural, …

Youth With Juvenile Justice Contact: Special Considerations In Measurement, Anne Elizabeth Biehl

Electronic Theses and Dissertations

Students who have contact with the juvenile justice system are a particularly vulnerable and unique school-aged population. The risk factors that plague the likelihood of justice-involvement are numerous and inter-connected. Early experiences of trauma and adversity, limited familial and financial capital, and challenges with mental health all contribute to increased likelihood of youth contact with juvenile justice systems. Despite said risk factors effects on young people overall, youth of color are particularly susceptible to become justice-involved. School and community discipline statistics are grossly, racially disproportionate.

Pathways from schools to the justice system have been widely investigate in the literature. There …

Social Support Among Undergraduate Students: Measure Development And Validation, Heather M. Blizzard

Electronic Theses and Dissertations

Being born into circumstances of low-income, having a racial minority status, and/or non-college educated families dwindle the opportunities for many students to obtain a college degree (Cox, 2016; Engle & Tinto, 2008; Jenkins et al., 2013). While many institutions of higher education have diligently worked to develop programs geared towards attending the educational inequalities among diverse student populations, there is still a great need for programs centered on the inequalities surrounding social support (Cox, 2016; Ward et al., 2012; Soria & Stebleton, 2012).

The purpose of this study was to develop and assess a measure to examine perceived social support …

Cellular And Developmental Insights Into The Early Evolution Of Muscle, Jeffrey J. Colgren

Electronic Theses and Dissertations

Whereas a great deal has been learned about the molecular underpinnings of morphological evolution in animals, much less is known about the origin of novel cell and tissue types. During the time in which the earliest animal lineages were diversifying, fundamental cell and tissue types, such as muscles, arose. Sponges are one of two animal lineages that lack muscles, yet they undergo coordinated full body contractions. Whereas the signaling processes have been studied, the physical mechanisms of contraction are completely uncharacterized. The main purpose of this work is to understand the primary contractile tissue of the sponge Ephydatia muelleri, …

Controlling Transition Metal-Catalyzed Alkyne Annulations Utilizing Polarized Ynol Ethers, Brandon L. Coles-Taylor

Electronic Theses and Dissertations

Transition metal-catalyzed alkyne annulations have developed into incredibly powerful synthetic tools over there the past quarter century. These reactions provide rapid access to important organic scaffolds such as indole, quinoline, isoquinoline, indene, and isocoumarin scaffolds. Transition metal mediated alkyne annulations have proven invaluable in synthetic fields, such as natural product total synthesis, by offering efficient pathways to otherwise synthetically difficult to access substrates.

Foundational works performed by chemist such as Larock, Ackermann, Satoh, and Miura have been established through relying upon the usage of symmetrical alkynes. When unsymmetrical alkynes are used in annulation processes mixtures of regioisomers are often isolated. …
