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 …

Pivotal Perceptions: A Phenomenological Exploration Of Trauma-Informed Practices In An Urban School, Marni Choice-Hermosillo

Electronic Theses and Dissertations

This phenomenological study sought to examine the experiences of teachers in an urban K-8 school after a system-wide whole school implementation of trauma-informed practices. The practices teachers implemented in their classrooms that aligned with their personal perceptions of trauma-informed practices and its efficacy were explored. Additionally, the personal and professional barriers to implementation were also investigated. Identified practical strategies at both the elementary and middle school levels included establishing and maintaining relational trust and classroom community, actively teaching emotional regulation skills, and teaching and reinforcing rituals, routines and expectations throughout the school year. Lack of confidence and previous personal assumptions …

The subquestions are: (a) how do students describe the impact of a theatre arts program in relation to academic learning outcomes?, (b) how do students describe the impact of a theatre arts program in relation to non-academic learning outcomes? The study follows …

“The Gates Are Closed Here”: A Mixed Methods Study Examining The Lived Experiences Of Black South African Township Youth, Jason St. Mary

Electronic Theses and Dissertations

South African Black township youth encounter immense risks within their environment, with little opportunity for perceived success. The Langa Township, the oldest established segregated community in Cape Town, South Africa, is enveloped in massive unemployment rates, substantial poverty, and violent gangsterism. Extensive literature exists in North America on the relationship between positive youth development (PYD) and successful outcomes for young individuals, although there is limited research examining the framework in an international context. Due to historical oppression forced on South African youth, postcolonial theory provides a critical foundational component to PYD in the study. This mixed methods study examined the …

Sorting Of Cargo Proteins Within The Regulated Secretory Pathway: The Peripheral Membrane Protein Hid-1 As A Sorting And Vesicle Biogenesis Factor, Blake H. Hummer

Electronic Theses and Dissertations

Large dense core vesicles (LDCVs) form at the trans-Golgi network (TGN) and mediate the regulated release of neuropeptides and peptide hormones. Despite their central role to physiology, the mechanisms controlling biogenesis and sorting to LDCVs is not well understood. Optimizing the retention using selective hooks (RUSH) method in neuroendocrine cells, we show it is possible to visualize sorting to the constitutive and regulated secretory pathways in real-time and that the bulk of transmembrane LDCV cargoes do not sort directly onto LDCVs, but exit the TGN into non-regulated vesicles to be incorporated to LDCVs at a later step. Additionally, we characterize …

Discrepancy Inequalities In Graphs And Their Applications, Adam Purcilly

Electronic Theses and Dissertations

Spectral graph theory, which is the use of eigenvalues of matrices associated with graphs, is a modern technique that has expanded our understanding of graphs and their structure. A particularly useful tool in spectral graph theory is the Expander Mixing Lemma, also known as the discrepancy inequality, which bounds the edge distribution between two sets based on the spectral gap. More specifically, it states that a small spectral gap of a graph implies that the edge distribution is close to random. This dissertation uses this tool to study two problems in extremal graph theory, then produces similar discrepancy inequalities based …

Nurturing Excellence: A Case Study Of High School Learning Environments For The Gifted, Ryan A. Mcclintock

Electronic Theses and Dissertations

The nuanced and complex cognitive and social-emotional needs of high school gifted learners are not sufficiently met through accelerated coursework like Advanced Placement and International Baccalaureate alone. Addressing their needs requires the design, implementation, and leadership of programming that maximizes their agency, curiosity, and confidence. Such programming should be fully modern in its conception and allow gifted high school students to construct and share products of their learning with respect to issues of global importance. The purpose of this study was to explore high school learning environments designed to maximize the agency, confidence, and curiosity of gifted and talented secondary …

Fostering Trauma-Informed Schools By Considering The Experiences Of Teachers In Working With Trauma-Exposed Students, Allison A. Stiles

Electronic Theses and Dissertations

High rates of trauma exposure among youth in the United States and the detrimental effects of trauma on students’ psychosocial and academic outcomes are well-established. Such findings have engendered the emergence of trauma-informed schools across the nation. While research regarding trauma-informed schools has understandably focused on the needs of students, shockingly little is known about teachers’ experiences in working with trauma-exposed students. In particular, very few studies have examined the relationship between teachers’ indirect exposure to student trauma and related symptoms of secondary traumatic stress (STS), as well as factors that may predict STS levels or explain variation in the …

A Qualitative Study Of Non-Relational Foster Families Experiences Navigating The Education System, Emma Grace Topf

Electronic Theses and Dissertations

This qualitative study used a phenomenological approach to capture the lived experience of non-relational foster families navigating the Colorado public education system. While most research on children in foster care looks at all sub-populations of foster care combined, this is the first known study to focus solely on non-relational foster families navigating the education system. I explored non-relational foster parents experience navigating the education system for the school-age children in their care through a semi-structured two-interview approach. Four levels of data analysis were completed (descriptive coding, emergent coding of themes, a priori coding of research questions, and a priori coding …

Sensitivity Of Radical Sam Enzyme Mftc To Molecular Oxygen, Vishnu Govindarajan

Electronic Theses and Dissertations

MftC is a radical S-adenosyl L-methionine (SAM) enzyme that catalyzes the first step in the production of mycofactocin. It is a ribosomally synthesized post-translationally modified (RiPP) redox cofactor shown to be essential for the survival of bacteria in the Mycobacterium genus in the presence of cholesterol as a carbon source and for the sequestration of ethanol. MftC catalyzes the C – terminal decarboxylation of tyrosine and the subsequent cross-linking of tyrosine to the penultimate valine on the precursor peptide MftA. The product formed out of the reaction is processed into mycofactocin in downstream processes. The bacteria in the Mycobacterium tuberculosis …

Audience Segmentation Ethics In Health Promotion, Uyen Lili Le

Electronic Theses and Dissertations

Audience segmentation is a crucial component of health promotion campaigns as it is believed to support health-related campaigns to achieve greater benefits. However, there are numerous concerns about the ethicality of audience segmentation. For instance, Newton, Newton, Turk, and Ewing (2013) stated that audience segmentation can create inequalities between different groups of audiences. In addition, unintended audience and consequences are often excluded from health campaign planning and execution. These factors can negatively affect the campaign by creating adverse impacts. As a matter of fact, the prominent challenge of health promotion is sustaining the connection between ethics and effectiveness for promotional …

Climate Change And Seed Security Among Smallholder Farmers In Northern Ghana, Michael Biwalib Madin

Electronic Theses and Dissertations

Smallholder agriculture is highly susceptible to climate variability and change. According to recent projections by the Intergovernmental Panel on Climate Change, this sensitivity would likely increase in the coming decades, with more erratic rainfall, prolonged dry periods, shorter growing seasons, and seed germination failures. In the African context, the mechanisms through which these ecological stressors would affect seed security are poorly understood. Drawing upon a case study of semi-arid Ghana, this study examines climate change impacts on seed security among smallholder farmers. It adopts a mixed-methods approach with intensive fieldwork in two farming communities. Conceptually, the study uses a political …

Performing Ir, Charles Darwin Lulevitt

Electronic Theses and Dissertations

This research is an attempt to create a new way of understanding international relations, which is defined here as knowledge and practice that informs us of the nature, goals, and actors of international politics. At the core of the research is a simple concern, but one I am still rather unsure I have thought of enough: what does it mean to create a different discourse? The argument made is that international relations as we know it, is a discourse centered on state, sovereignty, and anarchy, and also white, hegemonic masculine culture, which forces us to maintain that culture’s social dominance. …

Quantification Of Dynamic Epithelial Sheet Architecture In Botryllus Schlosseri Using 2-D & 3-D Image Analysis, Roopa Madhu

Electronic Theses and Dissertations

Epithelial tubules form critical structures in various body tissues; how- ever, since they are difficult to access experimentally, their architecture and dynamics are not well understood. Here we examine the dynamic remodeling of epithelial tubes in vivo using a novel and uniquely accessible model system: the extracorporeal vasculature of Botryllus schlosseri (sea squirt). In Botryllus, massive retraction of blood vessels can be triggered without loss of barrier function, through (i) disrupting collagen crosslinking in the basement membrane using β-aminopropionitrile (BAPN); or (ii) disrupting the integrin pathway through inhibition of focal adhesion kinase (FAK). We performed stereographic projections of 3-dimensional …

Racially Diverse Adolescent Friendship Groups: A Phenomenological Research Study, Arielle Brooke Mottes

Electronic Theses and Dissertations

School psychologists and other school personnel are trained to engage in selfreflective and culturally humble practices to better serve an increasingly racially diverse student population. While most literature on cultural humility (CH) focuses on its development in professionals, this research study looks at its development in students experiencing the phenomenon of racially diverse friendship. Previous research has found there to be a significant relationship between Theory of Mind (ToM) and social competence. The intended purpose of this study was to explore the possible relationship between ToM and CH amongst high school students who are part of racially diverse friendship groups. …

Unsettling The American Old West: Women Of Color Write The Archives, Alison Turner

Electronic Theses and Dissertations

This dissertation gathers Louise Erdrich’s Four Souls (2004), Maxine Hong Kingston’s China Men (1977), and Valeria Luiselli’s Lost Children Archive (2019) into a literary corpus that I call postwestern histories. Building on scholarship that situates these novels in Native American, Chinese American, and Mexican/American literary traditions, I show how these novels simultaneously cross bounds of ethnic literary genres to unsettle a dominating narrative of the United States West that roots Anglo expansionist experiences as foundational in archives, historiographies, and literary canons. This unsettling occurs in postwestern histories through three shared characteristics: prioritization of communities that are underrepresented in archival holdings, …

Rock Glacier Development In The San Juan Mountains, Brandon K. Bailey

Electronic Theses and Dissertations

Rock glaciers are common landform features found in deglaciated alpine areas. 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 …

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 …

Working For A Living: A Terror Management Theory Approach To Finding Meaning In Vocation, Julian T. Frazier

Electronic Theses and Dissertations

Many individuals spend approximately a third of their lives either working, receiving training or education for work or otherwise engaged in their career. While the current literature attempts to discern the many roles that work can play in our lives, it only scantly explore the existential nature of work in relation to death and mortality. Terror Management Theory provides a framework explaining how increases in awareness of our mortality influences our behavior and beliefs. By studying work constructs from the lens of Terror Management Theory, we seek to gain insight on the potential role that work plays in bolstering psychological …

When Repatriation Doesn’T Happen: Relationships Created Through Cultural Property Negotiations, Ellyn Demuynck

Electronic Theses and Dissertations

This thesis analyzes the discourse of repatriation in connection to the Encounters exhibition held by the National Museum of Australia in 2015. Indigenous Australian and Torres Strait Islander artifacts were loaned to the Australian museum by the British Museum. At the close of the exhibition, one item, the Gweagal shield, was claimed for repatriation. The repatriation request had not been approved at the time of this research. The Gweagal shield is a historically significant artifact for Indigenous and non- Indigenous Australians. Analysis takes into account the political economy of the two museums and situates the exhibition within the relevant museum …

Empathy And Understanding: The Impact Of Gifted Adults In The Field Of Gifted Education, Laura N. Boroughf

Electronic Theses and Dissertations

This study examines the perceptions of gifted adults, who are educators, in order to understand the empathy and advocacy that comes with a shared childhood experience. This is a qualitative study that used narratives to voice the experience of the gifted child through the memory of eight gifted adult educators. These memories, and reflections on identification, were told through interviews. Themes emerged related to empathy, advocacy, and cognitive dissonance, as well as imposter syndrome, career readiness, gifted minorities and the positives of gifted programming. Ultimately, it was found that gifted programming is overwhelmingly a positive experience and mirrors the statement …

“Because We Are Catholic”: Music As A Bridge Between Identities Within The Catholic Community Of South India, Johnathan Theodore Travis Rhodes

Electronic Theses and Dissertations

In this thesis, I argue that the music of the Catholic Church of South India, which draws from Indian and Western music genres, functions as a cultural bridge allowing the worshiper to express a distinctively Catholic identity without distancing themselves from their Hindu roots. This cultural connection reinterprets Karnatak musical styles, practices, and traditions as distinctively Catholic rather than Indian or Hindu. Thus, Indian cultures are recontextualized within a Catholic paradigm, as these practices are regarded as Catholic regardless of their historical, cultural, or religious origin. These identities, Indian and Catholic, are not in tension with one another, but instead, …

Automated Recognition Of Facial Affect Using Deep Neural Networks, Behzad Hasani

Electronic Theses and Dissertations

Automated Facial Expression Recognition (FER) has been a topic of study in the field of computer vision and machine learning for decades. In spite of efforts made to improve the accuracy of FER systems, existing methods still are not generalizable and accurate enough for use in real-world applications. Many of the traditional methods use hand-crafted (a.k.a. engineered) features for representation of facial images. However, these methods often require rigorous hyper-parameter tuning to achieve favorable results.

Recently, Deep Neural Networks (DNNs) have shown to outperform traditional methods in visual object recognition. DNNs require huge data as well as powerful computing units …

Performances Of An Able, Academic Mind, Caleb Green

Electronic Theses and Dissertations

Western culture individualizes issues of public health. This is especially clear in academic life, where the structures of the university disable atypical bodies and minds in order to force them to simultaneously perform the roles of scholar, teacher, and colleague. The university not only fails to accommodate afflicted minds and bodies, it also produces more precarity in the process. This project is a performance ethnography of my time in the academy, starting with my life as an undergraduate being disciplined into academic life, moving toward recruitment for graduate school, and ending with events surrounding the construction of this very project. …

Using Multi-Source Data To Assess The Dynamics Of Socioeconomic Development In Africa, Xuantong Wang

Electronic Theses and Dissertations

Frequent and rapid spatially explicit assessment of socioeconomic development is critical for achieving the Sustainable Development Goals (SDGs) at both national and global levels. In the past decades, scientists have proposed many methods for monitoring human activities on the Earth’s surface on various spatiotemporal scales using Defense Meteorological Satellite Program Operational Line System (DMSP-OLS) nighttime lights (NTL) data. However, the DMSP-OLS NTL data and the associated processing methods have limited their reliability and applicability for systematic measuring and mapping of socioeconomic development. This research utilizes Visible Infrared Imaging Radiometer Suite (VIIRS) NTL and the Isolation Forest (iForest) machine learning algorithm …

The Casc Framework: An Assessment Model For Students With Intellectual And Developmental Disabilities, Laurel A. Snider

Electronic Theses and Dissertations

School psychologists pay a critical role in providing assessment and intervention services within the realm of special education. Within this role, they are highly likely to interact with students with intellectual and developmental disabilities (IDD). Students with IDD are characterized by significantly lower than average cognitive and daily living skills that may be comorbid with difficulties with communication, social skills, or other domains. With these differences in mind, dominant assessment practices have been criticized as lacking social and empirical validity when applied to this population. Although students with IDD frequently undergo evaluations, they continue to face significantly poorer post-school outcomes …

Cellular And Organismal Ramifications Of De Novo Purine Synthesis Dysregulation, Randall Craig Mazzarino

Electronic Theses and Dissertations

Purines are a class of nitrogenous bases and are essential small molecules to life. Purines are used within the cell as genetic information carriers, energy currency, signaling molecules, and cofactors for multiple processes. They are formed through de novo and salvage pathways found in cells across the phylogenetic tree. The substrates of enzymes within de novo purine synthesis are known to influence other processes within the cell, such as energy homeostasis. In humans, de novo purine synthesis disorders are rare, with around 100 people identified. These patients exhibit a range of phenotypes, with varying degrees of mental retardation, seizure activity, …

How 6-12th Grade Staff Support Students With Depression: A Pilot Study To Develop Measures Of Implicit Associations, Explicit Attitudes And Helping Behavior, Paul M. Thompson

Electronic Theses and Dissertations

Students with emotional disabilities are disproportionately suspended and expelled in K-12 schools. Attribution theory suggests individuals are less likely to provide assistance to others if they believe the individuals are responsible for their own difficulties. To test attribution theory, this study created new measures of explicit attitudes and implicit associations of licensed 6-12th grade staff regarding students with depression as well as a helping behavior measure of staff toward students with depression. The survey was distributed within a single school district in the western United States. A majority of the sample (N = 52) held a mental health license (60%), …
