Taking Flight: An Independent Living Facility For Emancipated Foster Youth, Kristy Mcdaniel Leitzel

Theses and Dissertations

Motivation

Many of us think about foster care in the context of younger children removed from home. However, little thought is given to youth that age out of the foster care system and the associated challenges and risks they face, namely in the area of housing.

Youth in foster care often receive minimal support in making the transition to independence and are frequently forced into instant adulthood. They are faced with an abrupt end of support at a time when they have not yet mastered the educational, social, or economic survival skills necessary to be independent in the community (Haas, …

Small Mammal Community Ecology In A Northern Grassland, Lynda Lafond

Theses and Dissertations

I studied grassland small mammal community ecology at UND’s Oakville Prairie, in Grand Forks County, North Dakota summers 2018-2021. Specifically, I was interested in small mammal richness and abundance, investigating their habitat associations, investigating their phenotypic variation, and understanding their diets. I trapped small mammals for five consecutive nights at the end of June to early July 2018 – 2021. I also measured plant community composition and structure metrics. Over the four years, I captured 985 individuals from 11 species. Species richness and abundance varied spatially and temporally across the site. I most frequently captured meadow voles (Microtus pennsylvanicus), mice …

A Face Recognition Method Using Deep Learning To Identify Mask And Unmask Objects, Saroj Mishra

Theses and Dissertations

At the present, the use of face masks is growing day by day and it is mandated in most places across the world. People are encouraged to cover their faces when in public areas to avoid the spread of infection which can minimize the transmission of Covid-19 by 65 percent (according to the public health officials). So, it is important to detect people not wearing face masks. Additionally, face recognition has been applied to a wide area for security verification purposes since its performance, accuracy, and reliability [15] are better than any other traditional techniques like fingerprints, passwords, PINs, and …

Role Of Aurora Kinase A, Rab4a, And Endolysosomes In The Development Of Alzheimer’S Disease-Like Pathology, Zahra Afghah

Theses and Dissertations

Endosomes and lysosomes (endolysosomes) are organelles that play key roles in cell survival and cell death. These acidic intracellular organelles are the principal sites for intracellular hydrolytic activity required for the maintenance of cellular homeostasis. Endolysosomes are involved in the degradation of plasma membrane components, extracellular macromolecules, as well as intracellular macromolecules and cellular fragments. Understanding the physiological significance and pathological relevance of endolysosomes is now complicated by relatively recent findings of physical and functional interactions between endolysosomes and other intracellular organelles including endoplasmic reticulum, mitochondria, plasma membranes, and peroxisomes. Indeed, evidence clearly indicates that endolysosome dysfunction and inter-organellar signaling …

Internet Training Modules Targeting Home-Based Parent Involvement With Students In Early Childhood Special Education, Nicole Marie Reybok

Theses and Dissertations

Parental engagement is an essential element in the social-emotional and academic achievement of students. However, barriers to this involvement continue to exist. Barriers may take many forms including time, school and staff perceptions and bias, power dynamic, communication with teachers, curriculum, and differences in language and culture. Barriers to parent engagement are typically increased for parents of children with special education needs. Therefore, it is the responsibility of school staff to identify barriers that may exist for families and help them to develop solutions to overcome those barriers. This quantitative study investigated possible barriers to home-based parent involvement in Early …

The Impact Of Injury On Depression In Athletes: A Systematic Review, Nergis Akkaya

Theses and Dissertations

There are nearly 500,00 collegiate and professional athletes in the United States, and studies have shown how physical and mental demands of practice and competition (e.g., overtraining, exhaustion, injury) in addition to other external elements (e.g., trauma, retirement) adversely impact mental health. Injuries create a variety of emotional responses some of which can negatively affect athlete well-being. The focus of this systematic review was to build connections between mental health and sport and address two primary research questions:1. In what ways do injuries impact athlete depression? 2. How is depression experienced among athletes as a result of an injury? A …

Translocation Of Yops By Yersinia Pestis Into Canine Cell Lines, Betsy Louise Young

Theses and Dissertations

Yersinia pestis, the causative agent of plague, secretes a set of virulence proteins called Yops when in contact with eukaryotic cells. A subset of these Yops is translocated directly into the cytosol of the host eukaryotic cells by the type III secretion system. Using a protein tag-based reporter system, this study is focused on the translocation of these Yops into the cytosol of canine derived cell lines: MDCK and DH82. The MDCK cell line is a canine derived epithelial cell line, and the DH82 cell line is a canine derived monocyte cell line. The reporter system uses a phosphorylatable peptide …

Trajectories Of Medication Non-Adherence With Time-Varying Predictors And Association With Health Outcomes: A Comparison Of Classical Statistical Methods With Machine Learning Algorithms, Vasco Pontinha

Theses and Dissertations

Background: Medication adherence is a major obstacle to improving health care outcomes in long-term therapies for chronic diseases. According to the World Health Organization, interventions for improving medication adherence can have a higher impact on the health of the population than any other advance in medical treatments. Approximately 125,000 individuals die every year in the U.S. because of non-adherence to medication, representing societal costs of $100-289 billion. Previous research has successfully used group-based trajectories methods to identify similar longitudinal medication adherence trajectories. However, medication adherence is not an isolated behavior and is influenced by many factors that current interventions fail …

Landscape Ecology Influence On Population Dynamics And Gene Flow: A Muskrat’S Tale, Ayla A. Morehouse

Theses and Dissertations

Understanding movement patterns across a landscape is an essential tool for wildlife managers to understand and predict population dynamics, interactions, and susceptibility to disease and environmental changes. Part of this is due to population spatial synchrony being driven by three primary factors: dispersal, the “Moran Effect”, and trophic interactions. We seek to understand if dispersal may play a larger role in population synchrony and, if so, what landscape features may hinder the movement of muskrats (Ondatra zibethicus), a small semiaquatic mammal that relies on ditches and shallow wetlands for habitat and local movement. In this study we genotyped eleven microsatellite …

Genetic Breed Association And Contraceptive Response Gwas Of The Feral Horses (Equus Caballus) Of Theodore Roosevelt National Park, Melissa Amy Thompson

Theses and Dissertations

Theodore Roosevelt National Park (TRNP) is home to a herd of feral horses (Equus caballus) which were present on the landscape prior to the establishment of the park and are now maintained as a living history demonstration herd. I used genomic analyses to investigate the TRNP horses’ relatedness to other breeds and the genetic basis for variation in response to a contraceptive vaccine. DNA from 118 horses was genotyped for 70k SNPs spread evenly across the genome. To clarify the relationship of this herd with other horses, I used population genomic analyses to compare the TRNP genotypes to a dataset …

Associations Between Handgrip Strength Asymmetry And Health Related Quality Of Life Among Canadian Adults: An Analysis Of The Canadian Health Measures Survey, Jessica Lembke

Theses and Dissertations

Background: Health related quality of life (HRQOL), a measure of perceived quality of health is significantly related to current and future health. Handgrip strength (HGS) asymmetry is an aspect of muscle function that can be measured using handheld dynamometry. While several studies have examined relationships between HGS asymmetry and HRQOL, few have used nationally-representative data, and none have used Canadian data. The aim of this study, therefore, was to examine the association between HGS asymmetry and HRQOL in a nationally-representative sample of Canadian adults.

Methods: A secondary analysis of cross-sectional data from cycles 5 and 6 (2016–17 and 2018–19) of …

In the first study, undergraduate physiology student participation within online asynchronous peer group systems modeling activities was associated with progressive improvement on multiple choice question answer …

Examining Cultural Identification And Substance Use Among American Indian And Caucasian Adults, Lynn Ruth Martell

Theses and Dissertations

Previous research suggests American Indians (AIs) demonstrate higher levels of substance use and related consequences. AIs have experienced historical trauma through colonization which has created shifts in the way AIs conceptualize their identity. However, the literature on cultural identification as an influencing factor of substance use among AIs is inconsistent. The current study examined alcohol and drug use/related consequences, collective self-esteem, and cultural identification among 213 AI (n = 44) and Caucasian (CA; n = 169) adults via online surveys. Results indicated higher scores on the American Indian Cultural Identification (AICI) scale was a predictor for increased alcohol and drug …

Development Of Biomass-Derived Nanoparticles For Biological And Medical Applications, Sarah Elizabeth Reagen

Theses and Dissertations

Quantum dots (QDs) are a subset of nanoparticles (NPs) that have several unique optical and electrical properties that make them viable for fluorescent cell labeling applications. However, these QDs in the past were composed of toxic heavy metals such as lead and cadmium, and therefore, graphene-based QDs (GQDs) have been examined as an alternative material for these cell labeling applications for their increased biocompatibility. Furthermore, GQDs can produced singlet oxygen (1O2) for photodynamic therapy (PDT), making them capable of being used as a PS agent for cancer treatment. Additionally, hollow mesoporous silica nanoparticles (hMSNs) are capable of being an alternative …

Retired Indigenous And Non-Indigenous College Student Athletes' Mental Health Relating To Athletic Identity, Cultural Identity, And Career Transition, Victoria Williams

Theses and Dissertations

To date, empirical studies have investigated the transition or retirement phase, following the conclusion of a student-athletes’ four-year career as a comparison between student-athletes and non-athletes. Specifically, when investigating these constructs, researchers have failed to thoroughly investigate the role cultural identity may play in mitigating psychological symptoms during the transition phase. As such, this study will seek to investigate both Indigenous and non-Indigenous retired college student- athletes, during the transition phase, in terms of the degree to which they identified with their athletic identity, cultural identity and career transition. It is expected those retired Indigenous and non-Indigenous student- athletes who …

Data Driven Approach To Saltwater Disposal (Swd) Well Location Optimization In North Dakota, Kalyanaraman Venugopal

Theses and Dissertations

The sharp increase in oil and gas production in the Williston Basin of North Dakota since 2006 has resulted in a significant increase in produced water volumes. Primary mechanism for disposal of produced water is by injection into underground Inyan Kara formation through Class-II Saltwater Disposal (SWD) wells. With number of SWD wells anticipated to increase from 900 to over 1400 by 2035, localized pressurization and other potential issues that could affect performance of future oil and SWD wells, there was a need for a reliable model to select locations of future SWD wells for optimum performance. Since it is …

Non-Binary Gender Identity Development: A Qualitative Study, Trevor Waagen

Theses and Dissertations

Gender identity development models in psychology for transgender individuals have typically combined the experiences of binary transgender and non-binary transgender people into the same group. However, differences may exist between the two communities. Therefore, the present study sought to explore the lived experiences of non-binary adults and their gender identity development process. Through the lens of grounded theory (Charmaz, 2014), semi-structured, qualitative interviews were conducted with 10 non-binary participants to collect rich data on their gender identity development process. Transcriptions were coded and reviewed to develop themes and categories. The themes included: Connection and relationships, intersectionality and culture, gender in …

The Changing Evaluations Of Black Skin, White Masks Throughout History, Paul Gonzalez

Theses and Dissertations

Black Skin, White Masks, produced in 1952 by Frantz Fanon is an iconic piece of decolonization literature in which he speaks out against the physical, psychological, social, and economic effects of colonialism in Africa and evaluations of his work have continually evolved throughout the last 70 years. From 1952 to 1960, evaluations of his book was mostly confined in France, then in 1960 to 1968 his work was actively used in America as a guide on achieving political freedom for African Americans and analyzing the Civil Rights Movement and by 1990 onward, his book has been used to analyze …

The Role Of Slu7 In Spliceosome Function In Saccharomyces Cerevisiae, Sovira A. Chaudhry

Theses and Dissertations

The removal of introns from pre-messenger RNA via splicing in the nucleus is an essential step in gene expression. In recent decades, significant effort has been made to understand the chemical mechanisms of splicing reactions and the composition of the spliceosome that catalyzes them. Yet very little is known about the exact function of many splicing factors and small proteins within the spliceosome. Slu7, a pre-mRNA splicing factor, is essential during the second catalytic step of splicing because it interacts with several proteins and stabilizes the active site conformation. It has been found that Slu7 is involved in 3' splice …

Interpersonal Psychotherapy For Depressed Adolescents: A Systematic Review Of Quantitative Studies Exploring Effectiveness, Concomitant Findings, And Mediating And Moderating Variables, Luke Rex

Beyond The Binary Male: A Systematic Review Of Gender-Responsive Modifications To Risk Assessment Tools, Devin Randle

Theses and Dissertations

The American Psychological Association’s (APA) ethical guidelines identify that psychological tests should only be utilized on populations for which reliability and validity have been established. Likewise, the APA specifies gender to be nonbinary, encouraging clinicians to utilize inclusive and accurate measures. Following such guidelines when conducting violence risk assessments with women and individuals who identify as non-binary is currently challenging because a majority of violence risk assessment tools utilize a male normative sample. Applying such tools to populations beyond a cisgender male can result in misclassifications of individual risk. When risk is misclassified, improper interventions are utilized, which leads to …

Comparison Of Peak Skin Dose Calculated By Patient Radiation Dose Monitoring And Tracking Systems Versus Solid-State Detector Measurements, Vincent D. Gargaro

Theses and Dissertations

This study aims to compare the Peak Skin Dose (PSD) that patients obtain from fluoroscopy procedures. The study will show the differences between the PSD measured and calculated from a solid-state detector and the values the unit is displaying. Also, the study will compare PSD measurements from Patient Radiation Dose Monitoring and Tracking Systems (PRDMT). Numerous parameters need to be obtained to depict the PSD that a patient is receiving accurately. The PSD is crucial in assessing the potential biological effects of radiation.
