Mechanisms Of Cold Region Hydrologic Changes To Recent Wetting In A Terminal Lake Basin, Diane Frances Van Hoy

Theses and Dissertations

The recent changes in hydroclimatic conditions in the Northern Great Plains (NGP) have led to an increase in precipitation and wetland connectivity over the last few decades. The most recent wet period started at 2005 after the last NGP drought (1999-2004). The current wetting is expected to continue and could potentially last into 2038 and beyond. The increases in precipitation during the recent wet period yield an integrated response resulting in hydrologic changes in the NGP. However, the underlying mechanism of the hydrologic changes caused by recent wetting is poorly understood requiring a physically-based modeling framework in order to decipher …

Faculty And Staff Perceptions About Concealed Carry Initiatives And Their Effect On Campus Safety: A Multi-State Examination, Heidi Marie Ahl-Quanbeck

Theses and Dissertations

Concealed carry on campus is a polarizing debate affecting higher education today. Concealed carry refers to the carrying of a weapon in public while concealed from view. Prompted by isolated instances of gun violence as well as the changing gun culture within our society, ten states now permit weapons on campus as a result of legislation or institutional policy. Yet, little is known about faculty and staff perspectives on concealed carry on campus initiatives or how weapons could affect perceptions about campus safety. The purpose of this study is to better understand faculty and staff perspectives on concealed carry, to …

Quantifying Extravehicular Activity Performance Degradation Due To Sustenance Deprivation, Eryn Beisner

Theses and Dissertations

Modern EVAs (spacewalks) performed onboard the International Space Station require astronauts to endure up to twelve hours of intense mental and physical exertion without food, as they do not stop to eat nor do they currently have the capabilities to consume sustenance in their spacesuits. With the future of space exploration taking aim at the Moon, Mars, and beyond, EVAs are expected to become more demanding than ever. This is a pilot study to attempt to quantify astronaut performance during an EVA to determine if there is significant performance degradation because of acute starvation. Astronauts conducting EVA training at NASA’s …

Differentiating Active And Passive Fatigue States With The Use Of Electroencephalography, Kyle Anthony Bernhardt

Theses and Dissertations

With advances in automation technology, it is becoming essential to understand how automation affects human operators. A concern for the implementation of automation technology is the interactive effects it has with operator cognitive fatigue. Desmond and Hancock (2001) proposed that two types of fatigue can arise depending on the nature of the task: active and passive. Active fatigue results when operators must make constant perceptual-motor adjustments during high task demands, while passive fatigue results from operators executing little or no perceptual-motor adjustments during low task demands, similar to when automation is employed. The purpose of this study was to use …

Evaluation Of Nest Fate Classification Accuracy, Research Activities And Nesting Behaviors Of Least Terns And Piping Plovers On The Missouri River, Alicia Kyren Andes

Theses and Dissertations

Federally protected interior Least Terns (Sternula antillarum athalassos) and Piping Plovers (Charadrius melodus) are small shorebirds that nest on un-vegetated sand habitat, such as temporary sandbars and permanent islands along inland river systems in the United States including the Missouri River, during the summer months. Extensive monitoring and research has been conducted on the Missouri River populations because they are an important component of recovery efforts for both species; therefore, two of my primary objectives included: 1) estimate rates of and determine factors that influence nest fate misclassifications and 2) evaluate the impacts of research activities on shorebird nesting behaviors …

The Impact Of Implicit Attitudes On Behavioral Intentions To Prevent Suicide, Julio Brionez

Theses and Dissertations

The suicide rate in the United States of America continues to climb despite national strategies to reduce it (Centers for Disease Control and Prevention & National Center for Health Statistics, 2016; U.S. Department of Health and Human Services (HHS) Office of the Surgeon General & National Action Alliance for Suicide Prevention, 2012). What the strategies lack is mechanisms to target implicit attitudes (IAs) about suicide. This omission is important as IAs have been effective at predicting future suicide attempts (Nock et al., 2010). This study used an implicit association test of attitudes to suicide (IAT-SUICIDE) to examine IAs to suicide …

Investigating The Impact Of Offset Fracture Hits Using Rate Transient Analysis In The Bakken And Three Forks Formation, Divide County, North Dakota, Cody Lee Brown

Theses and Dissertations

The common development plan for operators in the Williston Basin has been to initially drill and complete one well in order to hold a 1280 acre spacing unit. Once acreage is secure across the asset, operators return to each spacing unit and drill infill wells. By the time infill wells are drilled, reservoir depletion from the original (parent) well can be observed within the spacing unit. Reservoir depletion increases the likelihood of existing wells experiencing inter- communication when infill wells are hydraulically fractured. Such inter-well communication, or frac-hits, often have detrimental effects on existing wells. As such, understanding the effect …

Teacher-Writer Perceptions On The Essence Of Writing: Influences, Identity And Habits Of Mind To Sustain A Writing Life, Shari L. Daniels

Theses and Dissertations

This body of work contains three articles that support the need for K-12 teachers to write

professionally and personally. The research sought to explore the questions of initial influences

to write, essentials to sustain writing and the relationship of teacher-writer development to self

authorship. Much of the previous literature produced by scholars, authors and teacher-writers

focus on the benefits for students when teachers are confident as writers. Student motivation to

write rests on the beliefs of the teacher who provides a model for writing as this shapes student

beliefs about themselves as writers. However, there is little research that provides …

The Involvement Of Polyol Pathway In Hypgerglycemia And Cadmium Toxicity In The Establishment Of Diabetic Neprhopathy, Bethany Anne Davis

Theses and Dissertations

Diabetic nephropathy (DN) is a major cause of end-stage renal disease (ESRD), where prolonged exposure to hyperglycemia induces damage to proximal tubule cells of the kidney. Since progression to ESRD correlates to pathological changes in the tubular segments of the kidney, the effects of hyperglycemia in the PT portion of the nephron may be particularly relevant to the progression of DN. Development of this disease also is likely to occur in the context of exposure to other renal toxins, and the heavy metal cadmium (Cd2+) may be the most relevant due to the accumulation of this metal in the major …

The War After Battle: Morale, Post-Traumatic Stress And Long-Term Welfare Of Combat Soldiers, Corey Doan

Theses and Dissertations

There is a historical, literary, and philosophical record of the effects of combat on mental health. Modern psychological research has focused on the relationship between combat deployment and a litany of mental health issues which include post-traumatic stress disorder (PTSD), various forms and manifestations of depression, substance abuse with a specific focus on alcohol, as well as social, family, and work-life functional impairment. This study introduces a customized 18-item Integrated Military Morale Questionnaire (IMMQ) which was designed to measure the proposed basic components of military morale: personal morale, cohesion, and esprit de corps. Data from 185 United States military members …

Wild And Domestic: Short Stories, Sara E. Dupree

Theses and Dissertations

Wild and Domestic is a collection of short stories set in rural northwestern Minnesota that center around themes of parenting, family, and the desire for stability and security. This desire for domestic harmony often comes into conflict with the characters’ strong desire for personal freedom, self-expression, sexual gratification, and a deeper connection to the natural world—desires that are linked to the concept of wild. The collection also invites readers to reflect on its animal characters. In many of the stories, animal characters, both wild and domestic, play a role in setting up the crisis or climax of the story by …

"Representative Bureaucracy" In Police Hiring Practices: A Case Study Of A Diverse Police Agency, Sara Franceen Edel

Intonation Production And Perception In Children With Developmental Language Impairment, Afua Blay

Theses and Dissertations

Studies on intonation production and perception in children with developmental language impairment (LI) have reported mixed outcomes. Some suggest that intonation processing is impaired in this population but others fail to find any evidence of such a deficit. The issue is further complicated by findings that indicate that these children perform poorly on some intonation tasks but not on others. The source of the discrepant findings is unclear. However, one shortcoming is that most previous studies do not report information on severity of LI of participants. Thus, it may be that the mixed findings on intonation processing in children with …

Women Engineering Majors' Choice To Stay: A Phenomenological Exploration Of Persistence Experiences, Victoria Morrissette

Theses and Dissertations

The historical underrepresentation of women in engineering persists for women engineering majors in college and once they enter the workforce. While some engineering disciplines have seen an increase in women students, overall the numbers still have fallen well behind other STEM disciplines despite years of research. Most studies on this issue have been quantitative and have looked at factors associated with why women leave engineering. This qualitative study, in contrast, gave women engineering majors the opportunity to share their experiences in answer to the question of why women choose to stay in an engineering major. Phenomenological methods, including semi-structured interviews, …

This study used a phenomenological approach to discover why and how faculty at a 4-year public university use the innovation of instructional video in their classrooms. The phenomenon studied was the adoption process and the motivation of the …

Academic Interventions In Secondary Schools: Examining Teachers' Perceptions Of Implementing A Multi-Tiered System Of Support, Shannon Mortrud

Theses and Dissertations

According to the National Center for Education Statistics (2015) only 34% of eighth grade students in the U.S. scored at or above proficient in reading and only 33% were at or above proficient in math. Reading comprehension is essential for the acquisition of knowledge in all coursework and those students who have reading deficits may experience increased academic failure. Deficits in math skills may also increase core academic failure for secondary students expected to complete rigorous courses in algebra and beyond. In a review of the literature, Blount (2012) deduced that academic failure is one of the main predictive risk …
