The Role Of Enso On Atmospheric Patterns In The Great Plains Of The United States In The Cesm2 Large Ensemble, Taylor Jean Dolan

Theses and Dissertations

The El Niño Southern Oscillation (ENSO) is a common teleconnection used for seasonal forecasts over the Great Plains of the United States, where the warmer (colder) conditions are associated with the positive (negative) phase. Precipitation is more nuanced due to the impacts of single events on seasonal precipitation. Understanding how ENSO impacts temperature and precipitation events in a warming climate is vital for understanding risks to the agricultural community. Unfortunately, deterministic climate simulations complicate matters as results can vary between different models due to internal variability.This study leverages the Community Earth System Model 2 Large Ensemble (CESM2) to explore the …

Restoring The Occupational Therapy Spirit In Hand Therapy Practice, Karrianna Iseminger

Theses and Dissertations

The dominant role psychosocial factors play in physical healing and disability perceptions of individuals with upper extremity (UE) conditions has been documented repeatedly in the literature for over 40 years. This population is at particular risk given the number of occupations requiring the functional use of one or both UEs for successful performance. However, occupational therapy practitioners (OTPs) specializing in hand therapy do not appear to have a shared practice or understanding of evaluation and intervention for psychosocial factors as they tend to focus mostly on the physical limitations of occupational performance. Therefore, the purpose of this three-article dissertation project …

The Effects Of Disconfirming Feedback On Multiple Tests Of A Witness's Memory, Kaden Alan Bollinger

Theses and Dissertations

Testing a witness’s memory more than once has been shown to decrease accuracy in subsequent tests, and providing a witness with disconfirming feedback has also been shown to reduce confidence levels and reduce accuracy after they have made a decision from a lineup. The current study aims to examine how disconfirming feedback affects a witness’s accuracy throughout multiple lineups, as well as looking to examine the reflector variables of reaction time and the “Remember, Know, Guess” (e.g. RKG) questionnaire. Participants who incorrectly chose a suspect from an initial target-absent lineup were given disconfirming feedback and randomly assigned to either a …

Novel Methods To Increase Carbon Mineralization Rates, Charles Ekpewani Kwaku Kporxah

Theses and Dissertations

Humans have contributed to climate change through anthropogenic emissions of greenhouse gases, such as carbon dioxide (CO2), methane, chlorofluorocarbons, and nitrous oxide, into the atmosphere. CO2 emissions contribute approximately 79% to the warming of the Earth's surface. Various tactics have been developed to slow down global warming and prepare for climate change, including carbon mineralization. Carbon mineralization is a process that converts CO2 into solid mineral forms, such as carbonates, emulating the natural weathering process of alkaline silicate rocks. However, the rate of natural weathering is slow, occurring on geologic time scales. Therefore, the goal of this research is to …

Constructing And Understanding Angler License Typologies And Response To Landscape Change, Michael James Lant

Theses and Dissertations

Usda Wildlife Services Management Efforts At The Grand Forks Wastewater Treatment Plant, Dorothy Celeste Daulton

Theses and Dissertations

Wildlife collisions with aircraft (wildlife strikes) are a costly and dangerous issue. In recent decades, wildlife strikes within airport boundaries have decreased partly due to on-airfield wildlife strike mitigation efforts. Landscape attractants surrounding airfields within an 8 km radius have been found to influence the occurrence of wildlife strikes by increasing wildlife presence and abundance on or near airfields. The effectiveness of mitigation efforts can be increased by extending operations to include landscape features in an 8 km radius from airports. However, not much is known about the long-term effects of wildlife strike mitigation operations when conducted on neighboring properties, …

One way to alter gut microbiome is to implement a prebiotic or probiotic. To determine if this is an effective treatment option for anxiety and depression, a literature review was conducted using primarily randomized clinical trials. PubMed was the primary database that was used for this research. Articles were sorted and chosen based upon applicability to the problem being …

Minimally Invasive Therapies In The Treatment Of Arthropathy, Steven Bateman

Physician Assistant Scholarly Project Papers

It is estimated that 27% of adults over 45 years of age suffer from osteoarthritis of the hip secondary to articular cartilage damage over the lifespan. Joint pain diminishes life quality, limits range of motion and overall activity, and frequently impairs basic ambulation. These functional deficits worsen the progression of comorbidities that are often referred to as lifestylerelated chronic disease as physical activity subsequently declines. This literature review explores the efficacy of minimally invasive therapies that precede and delay surgical intervention in adult patients experiencing functional limitations and pain in major joints. The study examines the effectiveness of various interventions, …

Population Genomics Provide Insight Into Ancestral Relationships And Diversity Of The Feral Horses Of Theodore Roosevelt National Park, Melissa A. Thompson, Blake E. Mccann, Turk Rhen, Rebecca Simmons

Biology Faculty Publications

Theodore Roosevelt National Park (TRNP) manages a herd of feral horses (Equus caballus) which was present on the landscape prior to the establishment of the park. The population presents a unique scenario in that it has experienced fairly intensive and well-documented management since the park's establishment, including herd size reductions, intentional introduction of diversity, and subsequent attempts to remove introduced lineages. This provides an interesting case study on the genetic effects of diverse evolutionary forces on an isolated feral population. To explore the effects of these forces and clarify the relationship of this feral herd with other horses, …

Probiotic Therapy For The Treatment And Prevention Of Bacterial Vaginosis, Chelsea Scheil

Physician Assistant Scholarly Project Posters

Bacterial vaginosis (BV) is a common presenting complaint in healthcare, and patients often experience recurrences at a frustrating rate. The mainstay of current treatment is antibiotic therapy, either via oral or vaginal route. When recurrences occur, stronger antibiotics are often employed. This current method of treatment does not address an underlying component that impacts infection recurrence and rate of recurrence- the patient’s baseline vaginal microbiome and the healthy bacteria that support it. To investigate the use of probiotics in bacterial vaginosis treatment, a comprehensive literature review was completed using databases PubMed and Embase. The results of this literature review confirm …
