Bound By Matter, Carlie Antes

School of Art, Art History, and Design: Theses and Student Creative Work

I view most aspects of life as being made up of tiny particles of matter that come together and synthesize to shape both our individual and collective human existence. Delicate threads are intricately woven together forming textiles and fabric. Tiny cellular particles shape all living species. Devices of human invention are mapped and constructed to aid in making sense of situations and surroundings. An accumulation of day-to-day moments coalesce to form complex memories and emotions. Each of these compositions are comprised of physical and/or emotional matter. This body of work utilizes the physical matter of my own lived experiences to …

This article explores how one higher education faculty learning community engaged in reflective practices in pursuit of their commitment to the inclusion of anti-racist content and pedagogy across their multidisciplinary curriculums. As a key initial step in engaging in this collaborative, cross-disciplinary work, they set out to consider collective definitions of key terms that are deemed critical to anti-racist pedagogy. This group engaged in a collaborative exploratory process to explore definitions and understanding of the following terms: whiteness, racism, race, racial equity, racial injustice/inequity, white supremacy, and anti-racism and document the reflective process by which the determination took place. Themes …

Practical Guidelines For Development Of A University-Wide Faculty Mentorship Program Using A Multimodal Mentoring Network Model, Matthew G. Schwartz

To Improve the Academy: A Journal of Educational Development

Formal faculty mentorship programs are a practical and effective pathway to enable faculty success in teaching, scholarship, and service and to enhance faculty satisfaction. Although informal mentoring relationships benefit some faculty, formal faculty mentorship programs ensure equitable access to mentorship for female faculty and faculty from diverse, underrepresented backgrounds. Formal faculty mentorship programs can utilize a variety of structures, each with their benefits and drawbacks. This article recommends a multimodal mentoring network model to harness the benefits of traditional dyadic mentoring, multiple-mentor mentorship, peer and near-peer mentorship, and topic- and affinity-based group mentorship and to confer the flexibility, adaptability, and …

Understanding The Participation Gap At Predominantly White Institutions: Examining Institutional Practices That Prevent Black Students From Studying Abroad, Jamil Funnah

Department of Educational Administration: Dissertations, Theses, and Student Research

Study abroad is an opportunity students in higher education increasingly participate in (Institute of International Education, 2022). However college Students of Color, particularly Black students, participate in study abroad at disproportionately lower rates when compared to their white peers. This case study seeks to understand the multiple influences that inform lower levels of Black student participation in study abroad. Using Gusa’s (2010) white institutional presence framework, I examine multiple data points within a singular site including institutional messaging, procedures, and students interviews. Findings showed that multiple reasons impact Black students' decisions to study abroad. Understanding the findings can lead to …

This study aims (1) to characterize the physical and biochemical traits of wheat and corn plants using RGB and hyperspectral imaging in the greenhouse, and (2) to estimate leaf nitrogen (N), phosphorus (P), and potassium (K) content using hyperspectral imaging and an analytical spectral device (ASD spectrometer) and compare the …

Extraction And Analytical Method For N-Nitrosoatrazine Using Liquid Chromatography Paired With Tandem Mass Spectrometry, Carolyn Billings

Honors Program: Senior Projects (Public)

Atrazine is an herbicide used in the United States to control weeds. When combined with nitrite, atrazine can be nitrosated to form N-nitrosoatrazine (NNAT) in vivo and in vitro under acidic conditions. Atrazine can also be metabolized to atrazine mercapturate, deethylatrazine (DEA), didealkylatrazine (DDA), and deisopropylatrazine (DIA). Atrazine is monitored in drinking water due to its possible carcinogenicity. The objective of this study was to develop extraction and analytical methods for NNAT, atrazine, and atrazine metabolites. An instrument detection limit, extraction methods comparison, and extraction method detection limit were determined. To compare methods, Fischer 344 rat tissue samples were …

Design Of Wythe Connectors For Concentrated Out-Of-Plane Loading Of Insulated Walls, Ammar Al-Maabreh, Fray F. Pozo, Marc Maguire

Durham School of Architectural Engineering and Construction: Faculty Publications

Partially composite concrete insulated wall panels must be designed to handle different types of loading, including out-of-plane concentrated loads. Currently, there is a lack of information that describes and helps engineers analyze the mechanics of axial load transfer for insulated wall panels for concentrated out-of-plane loads that may occur from lifting, handling, or floor/roof reactions. Such loading generates axial and shear forces in the wythe connectors, making it important to choose the type and quantity of connectors in the design process. This paper aims to develop a better understanding of out-of-plane point load mechanics on concrete sandwich wall panels. A …

Wakara's Waterscapes: Storytelling, Cartography, And Rhetorical Sovereignty On The Shores Of The Green River, Abbey O'Brien

Honors Program: Senior Projects (Public)

In the mid nineteenth-century, Wakara, a prominent Ute leader, witnessed the invasion of his homeland by Mormon settlers and mountain-men. He met the scouts and explorers who were sent out to examine the land and waterscapes, and who drew maps along their way. It was those same maps which were eventually used as tools to justify colonial expansion all across the Utah territories, Wakara’s home. But Wakara resisted. Employing his understandings of the roles that cartography and the written word played in Mormon and settler discourse, Wakara created his own maps in order to assert his Indigenous authority over the …

Diffractive Imaging Of Laser Induced Molecular Reactions With Kiloelectron–Volt Ultrafast Electron Diffraction, Yanwei Xiong

Department of Physics and Astronomy: Dissertations, Theses, and Student Research

Capturing the structural changes during a molecular reaction with ultrafast electron diffraction (UED) requires a high spatiotemporal resolution and sufficiently high signal-to-noise to record the signals with high fidelity. In this dissertation, I have focused on the development of a tabletop gas phase keV-UED setup with a femtosecond temporal resolution. A DC electron gun was employed to generate electron pulses with a high repetition rate of 5 kHz. The space charge effect in the electron pulse was ameliorated by compressing the 90 keV electron pulse longitudinally with a time varying electric field in an RF cavity. The velocity mismatch between …

Three Thingness: A Critical Introduction To The Collection, Kasey Peters

Department of English: Dissertations, Theses, and Student Research

The following project, "Three Thingness," consists of a critical introduction and craft essay on short story writing, and a sample of the collection Very Light in the End. The critical essay "Three Thingness" introduces a framework for evaluating short stories, and then evaluates a few key components undergirding the collection: gender, plot, and comic relief. Part postmodern realism and part absurst-lite^tm fiction, the collected stories depict characters as they navigate prescriptive narratives about bodies, gender, queerness, and illness.

A Device For Measuring Acoustic Output Intensity Of Transcranial Doppler Ultrasound Transducers For Comparison With Fda Regulations, Sarah Altman, Gregory Bashford, Benjamin Hage

Honors Program: Senior Projects (Public)

Transcranial Doppler Ultrasonography (TCD) is a non-invasive methodology which can evaluate cerebral blood flow velocity in real time. Single-element focused circular transducers placed on the scalp produce ultrasound waves capable of penetrating the skull with minimal aberration, enabling measurement of the Doppler shift. As such, TCD can measure blood flow velocity in the internal carotid and vertebral arteries, as well as the arteries of the Circle of Willis: the Anterior Cerebral (ACA), Posterior Cerebral (PCA), and Middle Cerebral Arteries (MCA). Intracranial aneurysm and ischemic stroke are serious conditions in which ballooning or occlusion of cerebral vessels cause insufficient perfusion, leading …

Does Being Known Matter? Analyzing The Effects Of Name Recognition By Instructor And Student, Brandon Bosch

Department of Sociology: Faculty Publications

Trying to learn the names of students is a challenging semester ritual for many professors and graduate students. In support of this endeavor, research suggests that learning students’ names promotes greater student participation and engagement (Auster and MacRone 1994; Pearson and Lucas 2011). However, both research and practical pedagogical advice has typically focused only on the importance of students believing that instructors know their names. Consequently, we know little about students feeling recognized by name by other students. To further explore this issue, this study analyzes both the predictors and outcomes of student name recognition. The results of the study …

Interface-Engineered Ferroelectricity Of Epitaxial Hf0.5Zr0.5O2 Thin Films, Shu Shi, Haolong Xi, Tengfei Cao, Weinan Lin, Zhongran Liu, Jiangzhen Niu, Da Lan, Chenghang Zhou, Jing Cao, Hanxin Su, Tieyang Zhao, Ping Yang, Yao Zhu, Xiaobing Yan, Evgeny Y. Tsymbal, He Tian, Jingsheng Chen

Department of Physics and Astronomy: Faculty Publications

Ferroelectric hafnia-based thin films have attracted intense attention due to their compatibility with complementary metal-oxide-semiconductor technology. However, the ferroelectric orthorhombic phase is thermodynamically metastable. Various efforts have been made to stabilize the ferroelectric orthorhombic phase of hafnia-based films such as controlling the growth kinetics and mechanical confinement. Here, we demonstrate a key interface engineering strategy to stabilize and enhance the ferroelectric orthorhombic phase of the Hf_0.5Zr_0.5O₂ thin film by deliberately controlling the termination of the bottom La_0.67Sr_0.33MnO₃ layer. We find that the Hf_0.5Zr_0.5O₂ films on …

Integrating And Optimizing Genomic, Weather, And Secondary Trait Data For Multiclass Classification, Vamsi Manthena, Diego Jarquín, Reka Howard

Department of Statistics: Faculty Publications

Modern plant breeding programs collect several data types such as weather, images, and secondary or associated traits besides the main trait (e.g., grain yield). Genomic data is high-dimensional and often over-crowds smaller data types when naively combined to explain the response variable. There is a need to develop methods able to effectively combine different data types of differing sizes to improve predictions. Additionally, in the face of changing climate conditions, there is a need to develop methods able to effectively combine weather information with genotype data to predict the performance of lines better. In this work, we develop a novel …
