Mountain Lions In North Dakota: A Public Opinion Survey, Theodore A. Darnell

Theses and Dissertations

Breeding mountain lion (Puma concolor) populations currently inhabit the western portion of North Dakota. In recent years, apparent increases in human-lion interactions across North Dakota, and other Midwest states, have challenged wildlife managers who strive to balance biological and social carrying capacities of these animals. In 2019, we surveyed 2,000 residents of North Dakota, USA, using a self-administered mail survey to discern knowledge of and attitudes towards mountain lions, and to explore whether the presence of these animals would influence decisions to recreate in western North Dakota. Our questionnaire included 12 questions designed to ascertain respondent attitudes towards mountain lions. …

The Impact Of Clinician Attachment Style On Burnout And Job Satisfaction: Introducing Mindfulness As A Mediator, Jill Marie Calderon

Theses and Dissertations

Attachment style is theorized to develop in childhood, as a result of the bonds that develop between child and caregiver. The research has shown individuals with an insecure attachment style are more at risk for job burnout and less satisfied with their jobs. This study proposed, mindfulness may be the internal process influencing the relationship between attachment style, burnout and job satisfaction. Mindfulness is defined as paying attention on purpose, in the present moment, nonjudgmentally and has found to be positively correlated with secure attachment styles. Additionally, mindfulness has shown to have a negative relationship with burnout and a positive …

Bio-Regenerative Life Support Systems Functional Stability And Limitations, A Theoretical Modeling Approach, Curt I. Holmer

Theses and Dissertations

Experiments with Ecological Closed Life Support Systems (ECLSS) for moderate sized crews have shown instability when supporting crews over long periods of time required for deep space travel. Tests such as Russia’s BIOS series, NASA’s Lunar-Mars Life Support Test Project (LMLSTP), ESA’s Micro-Ecological Life Support System Alternative (MELiSSA), and Japan’s Closed Ecology Experiment Facilities (CEEF) have shown that microalgae and higher plants combined with physical-chemical material converters can be a successful part of a Biological Life Support System or a Closed Ecological Life Support System. LMLSTP, MELiSSA, and CEBAS experiments as well as commercial Ecosphere products have proven stability at …

Influences On The Development Of Ethical Decision-Making In Speech-Language Pathology Students: A Phenomenological Study Of Graduate Students And Clinical Supervisors, Joni K. Mehrhoff

Theses and Dissertations

Speech-language pathologists (SLPs) serve as members of the interprofessional team for complex patients. As such, SLPs are required to uphold ethical practices and respond to the needs of patients, their families, healthcare organizations, and the interprofessional team. Speech-language pathology graduates are part of the ethical healthcare team during clinical experiences. Yet, limited research is available to define the development of student ethical decision-making. The purpose of this study was to explore what influences SLP graduate students and clinical supervisors ascribe to in the development of ethical decision-making. Participants included five SLP graduate students and six SLP clinical supervisors from accredited …

Electron Beam Irradiation As A Potential Lipid Decontamination Technique For Life Detection Instruments, Denise Kathleen Buckner

Theses and Dissertations

In the search for extraterrestrial life, identification of molecular biosignatures is a key technique. Lipids are important molecular biosignatures: they are ubiquitous to terrestrial life, survive for billions of years in the geologic record, can form biotically and abiotically (bearing molecular features indicating biogenicity), and are detected throughout the Solar System. Lipid-based life detection instruments require stringent contamination control to prevent false positives, but traditional decontamination techniques are unlikely to sufficiently remove lipid contamination without compromising instrument materials. This thesis investigates Electron Beam Irradiation (EBI) as a potential decontamination technique; five representative lipid standards, including palmitic acid, oleic acid, heneicosane, …

Automated Fractional Snow Cover Monitoring From Near-Surface Remote Sensing In Grassland, Anai Caparo Bellido

Theses and Dissertations

Snow cover is an important variable in both climatological and hydrological studies because of its relationship to environmental energy and mass flux. However, variability in snow cover can confound satellite-based efforts to monitor vegetation phenology.

This research explores the utility of the PhenoCam network cameras to estimate Fractional Snow Cover (FSC) in grassland. The goal is to operationalize FSC estimates from PhenoCams to inform and improve satellite-based determination of phenological metrics.

The study site is the Oakville Prairie Biological Field Station, located near Grand Forks, North Dakota. I developed a mostly semi-automated process to estimate FSC from PhenoCam images through …

An Exploration Of Indigenous Spiritual Microaggressions, Cerynn Dawn Desjarlais

This descriptive exploratory research is amongst the first to investigate Spiritual Microaggressions experienced by Indigenous Peoples across North America. Microaggressions can further be conceptualized and categorized as microassaults, microinsults, and microinvalidations. Participants who self-identify as Indigenous individuals ages 18 and over, from North America, who work in or are educated in the mental health field engaged in 60-90-minute interviews to explore the spiritual microaggressions incurred upon them. A total of 8 participants who identify as mental health professionals and graduate students in the mental health field were interviewed as an intensity sample. Participants discussed the implications of Indigenous Spiritual Microaggressions …

On The Potential Of Lignin As A Sintering Aid And Binder For Designing Porous Foams, Grant Christian Ellis

Theses and Dissertations

Lignin, as an abundant source of bio-renewable material, has been a subject of investigation for many years. Due to its chemically heterogenous and recalcitrant nature, 98% of the material is discarded as waste [3]. Laboratory groups have been exploring lignin’s potential as a value-added ingredient to promote biocompatibility, biodegradation, and substitute toxic, petroleum-based materials [4,6]. In our laboratory, lignin has been utilized as precursor for carbon foam, yielding highly porous structures after pyrolysis [5], and has also been shown to be compatible with other bio-waste materials [8]. The next stage of research focusses on controlled additions of Cu or Distiller’s …

Interferon-Γ Medaites Lung Damage Through The Hyper-Activation Of Ccr2+ Inflammatory Monocytes During Influenza Virus Infection, Mitchell Anthony Klomp

Theses and Dissertations

Influenza viruses (IV) have caused untold morbidity and mortality throughout the previous centuries. These viruses have caused several pandemics that have witnessed the loss of millions of lives. Today, IVs continue to circulate annually, and the efficacy of influenza virus vaccines are limited. As IV pandemics in 1918, 1957, and 2009 have shown the world, the push for a universal influenza vaccine has never been more relevant. While much research has been devoted to understanding the virology around IVs, the immunopathology of the host-pathogen axis has been less studied. Recently, there has been much attention on the role of the …

Evaluating Mixed-Mode Survey Designs For Collecting Deer And Fall Turkey Hunter Harvest Data In North Dakota, Ethan James Kalinowski

Theses and Dissertations

Achieving state wildlife agency biological goals for deer (Odocoileus spp.) and turkey (Meleagris gallopavo) rely on high quality data collection via hunter harvest surveys. Concomitantly, better information is needed to optimize best survey methods. From 2017 to 2019, we surveyed North Dakota, USA, deer and fall turkey hunters using a self-administered mail control survey and 3 mixed-mode internet/mail surveys to gain a better understanding of alternative survey designs that may be used to estimate harvest of game populations and inform future management efforts. Our first objective was to measure response rates across various segments of deer and fall turkey hunters …

At-Home Childcare Providers’ Perceptions Of Gardening With Children, Erin Lauckner

Theses and Dissertations

Children do not consume recommended amounts of fruits and vegetables, which has been correlated with negative health consequences. Gardening with children has been shown to positively impact children’s consumption of these foods. While research investigating gardening with children exists, much of this has been conducted with teachers and children in schools, and limited research has been conducted with childcare providers and preschool-aged children. Little research has been conducted about this topic with in-home childcare providers and the children under their care. This pilot study utilized a cross-sectional mixed methods research design through an online survey instrument. A convenience sample of …

Investigation Of The Neurological Manifestations Of Lyme Disease And The Impact Of Borrelia Burgdorferi On The Epigenetic Landscape Of Astrocytes, Derick Thompson

Theses and Dissertations

Lyme disease, caused by the spirochete Borrelia burgdorferi (Bb), is the most commonly reported vector-borne disease in the United States – with 30,000 cases being reported to the CDC annually, though it is estimated that 300,000 individuals are infected each year in the U.S [1–4]. Due to the medical treatment of the disease, this equates to an estimated $712 million - $1.3 billion in medical costs each year [5]. Conclusively, due to the continued geographical spread and increasing incidence rate, Lyme disease is becoming a greater public health threat throughout the world.

The symptoms of Lyme disease can range from …

Land Management And Plant Species Pattern Effects On Grassland Pollinator Services, Leslie Blaine Yellow Hammer

Theses and Dissertations

Invertebrate pollinator populations are widely recognized as declining because of anthropogenic activities that include changes in the amount and quality of available habitat, competition with introduced species, increased agricultural chemical use, and climate change. Because habitat and resource availability affect pollinator populations, land management may affect pollinator presence. My first aim was to determine if pollinator communities and habitat characteristics (available bare ground and floral resources) differed between grazed and idle grasslands within the Grand Forks County Grasslands of northeastern North Dakota, USA. Although available bare ground and plant species richness differed between grassland types, floral resources and pollinator communities …

Mitochondrial Utilization Of Competing Fuels Is Altered In Insulin Resistant Skeletal Muscle Of Non-Obese Rats (Goto-Kakizaki), Nicola Lai, Ciarán E. Fealy, Chinna M. Kummitha, Silvia Cabras, John P. Kirwan, Charles L. Hoppel

Electrical & Computer Engineering Faculty Publications

Aim: Insulin-resistant skeletal muscle is characterized by metabolic inflexibility with associated alterations in substrate selection, mediated by peroxisome-proliferator activated receptor 𝜹 (PPAR𝜹). Although it is established that PPAR𝜹 contributes to the alteration of energy metabolism, it is not clear whether it plays a role in mitochondrial fuel competition. While nutrient overload may impair metabolic flexibility by fuel congestion within mitochondria, in absence of obesity defects at a mitochondrial level have not yet been excluded. We sought to determine whether reduced PPAR𝜹 content in insulin-resistant rat skeletal muscle of a non-obese rat model of T2DM (Goto-Kakizaki, GK) ameliorate the inhibitory effect …

Physical Activity And Depression In Mothers Of A Child With A Special Health Care Need: Informing Future Interventions, Brianna Jean Black

Theses and Dissertations

In the United States, approximately 20 percent of all children have a special health care need. Additionally, mothers of a child with a special health care need have worse overall well-being, mental and physical health compared to mothers of typically developing children. Physical activity may improve depressive symptoms and overall health in these mothers; however, little is known about the acceptability of physical activity interventions for mothers of a child with a special health care need. Therefore, the primary aim of this study was to understand more about mother’s desire to use physical activity to improve depressive symptoms after having …

Examining Perceived In-Group Similarity And Out-Group Dissimilarity As Predictors Of Religious Intergroup Bias, Richard Clark Grove

Theses and Dissertations

People tend to feel more favorably toward others who share their beliefs and values. Religion can provide a quick estimate of ideological similarity. The religious values conflict model (Brandt & Van Tongeren, 2017) proposes that people high and low in religiosity are both prejudiced toward groups with dissimilar values. However, the role of dissimilarity in predicting religious intergroup bias has not been directly tested. A pilot study (N = 326) tested whether Christians and nonreligious people would demonstrate the patterns of intergroup bias predicted by the religious values conflict model. Additionally, the respective roles of perceived in-group and out-group dissimilarity …

Twice-Exceptional College Students Narratives: When Giftedness And Mental Health Intersect, Emily Dubord Hill

Theses and Dissertations

Gifted college students often arrive at universities with high GPAs and/or ACT/SAT scores. Their achievements in extracurricular activities such as in the arts, athletics, service, and leadership are well beyond the average student. To admissions representatives and faculty, these students look well-adjusted and successful on paper. However, many of these gifted college students come with unique challenges that go misunderstood, ignored, and underserved during their years in higher education—specifically involving their mental health.

There are copious amounts of literature on gifted K-12 students and their mental health behaviors but very limited research done on the gifted college student population. Although …

Home Range And Habitat Selection Of Gray Wolves (Canis Lupus) On Red Lake Indian Reservation And Surrounding Areas, June Levin

Theses and Dissertations

Every animal requires space where they can perform activities to survive and reproduce. For land animals, components of space use include area and habitat. Because most land animals are living on a human dominated landscape, understanding home range area and habitat needs is critical to their conservation. This is particularly relevant for threatened or endangered species such as the gray wolf (Canis lupus). The Minnesota Department of Natural Resources estimates home ranges and habitat use of wolves in northwestern Minnesota; however, a subset of this population lives within the bounds of Red Lake Indian Reservation, where The Red Lake Band …

Mapping Land Use And Land Cover Change And Its Impact On Landscape Structure And Amphibian Functional Connectivity In The Prairie Pothole Region, Taylor Holm

Theses and Dissertations

Monitoring land use and land cover (LULC) change and its effect on habitat availability and connectivity is crucial for species conservation and management. This is most efficiently accomplished at a sufficiently broad scale using remote sensing technology. Current approaches benefit from freely available data sources such as National Land Cover Database (NLCD), derived from 30 m Landsat imagery. However, temporal frequency and spatial resolution of NLCD may be insufficient for some applications. Specifically, 30 m resolution data may not detect small or narrow landscape features that may be important habitat for small animals such as amphibians. Other available data sources, …

A Study Of The Feasibility Of Growth, Extraction, And Industrial Scale Up Processing Of Microalgae Lipids., Jasmine Oleksik

Theses and Dissertations

The interest in microalgae as a plausible alternative to crop oils as a raw material in the form of triglycerides and free fatty acids (FA oils) for renewable fuels and chemicals is increasing and it is a widespread research topic at the lab scale. Microalgae contain a higher lipid content on a dry weight basis compared to oilseeds such as soybeans. Additionally, the growth and cultivation cycle of microalgae is 15 days, in comparison to soybeans where the cycle occurs once or twice annually. Despite these advantages, to date it has been uneconomical to produce microalgae oils in a world-scale …

These simulation outputs can be used to demonstrate the ways a forest grows over time. The user can …

Transformative Education In Agroecology: Student, Teacher, And Client Involvement In Co-Learning, Charles A. Francis, Anna Marie Nicolaysen, Geir Lieblein, Tor Arvid Breland

Department of Agronomy and Horticulture: Faculty Publications

Educational methods have evolved rapidly in agroecology, which is a complex and holistic field without a long history or the formal tradition of any single academic discipline. Definitions of agroecology have evolved from its initial conception as a marriage of agriculture with ecology, to an aggregation of different paths including science, practices, and movements, and recently as a broad appreciation of the ecology of food systems. In contrast with traditional courses that begin with a history of the discipline and review the contributions of early leaders, we have embraced phenomenology to firmly establish roots in students’ learning through their experiences …

Gwas: Fast-Forwarding Gene Identification And Characterization In Temperate Cereals: Lessons From Barley – A Review, Ahmad M. Alqudah, Ahmed Sallam, P. Stephen Baenziger, Andreas Börner

Department of Agronomy and Horticulture: Faculty Publications

Understanding the genetic complexity of traits is an important objective of small grain temperate cereals yield and adaptation improvements. Bi-parental quantitative trait loci (QTL) linkage mapping is a pow- erful method to identify genetic regions that co-segregate in the trait of interest within the research pop- ulation. However, recently, association or linkage disequilibrium (LD) mapping using a genome-wide association study (GWAS) became an approach for unraveling the molecular genetic basis underlying the natural phenotypic variation. Many causative allele(s)/loci have been identified using the power of this approach which had not been detected in QTL mapping populations. In barley (Hordeum …

Prediction Strategies For Leveraging Information Of Associated Traits Under Single- And Multi-Trait Approaches In Soybeans, Reyna Persa, Arthur Bernardeli, Diego Jarquin

Department of Agronomy and Horticulture: Faculty Publications

The availability of molecular markers has revolutionized conventional ways to improve genotypes in plant and animal breeding through genome-based predictions. Several models and methods have been developed to leverage the genomic information in the prediction context to allow more efficient ways to screen and select superior genotypes. In plant breeding, usually, grain yield (yield) is the main trait to drive the selection of superior genotypes; however, in many cases, the information of associated traits is also routinely collected and it can potentially be used to enhance the selection. In this research, we considered different prediction strategies to leverage the information …

Transparency After Carpenter, Hannah Bloch-Wehba

Faculty Scholarship

This brief invited response to Professor Matthew Tokson’s Foulston-Siefkin lecture on the Supreme Court's decision in Carpenter v. United States makes two contributions. First, I highlight the social, political, and economic factors at play in the Carpenter decision. The Carpenter Court recognized, in particular, that digital surveillance implicates the rights of more than just criminal suspects: it poses unique and unappreciated threats to public governance of policing. The decision, I argue, reflects longstanding preoccupations in Fourth Amendment decisions with protecting the “public” — particularly innocent third parties — from intrusive and baseless investigations. In so doing, I situate Professor Tokson’s …
