The Effects Of Active Vs Passive Recovery On Subsequent Bouts Of High Intensity Performance In Recreational Adult Runners, Matthew Mccreary

Theses and Dissertations

Background: Runners can perform training runs designed to elicit desired adaptations for future competition. When performed at a high-intensity, these running bouts will lead to fatigue that needs to be diminished to sustain the desired workload for the training session. Performing an active recovery or remaining passive are two methods that runners could use.

Purpose: The purpose of this study was to investigate the effects of active vs passive recovery on a subsequent running bout of 400 meters in recreational adult runners. It was hypothesized that the active recovery condition would maintain performance better than passive recovery.

Methods: A crossover …

Monitoring Changes On The Sheyenne National Grassland Using Multitemporal Landsat Data, Stefano Potter

Theses and Dissertations

Tallgrass prairies are one of the rarest ecosystems on the planet as up to 99% of their historical extent has been converted to agriculture. Once a prairie is converted there is often a loss of ecosystem services such as soil retention, carbon storage, water quality and a loss of biodiversity. It can take centuries to restore a native prairie after conversion has taken place. The Sheyenne National Grassland is managed by the U.S. Forest Service and contains the largest publicly owned tract of tallgrass prairie remaining in North America making it a highly valuable for conservation.

Ordinary least squares regression …

Distributed Team Communication Preferences: A Case Study Of Community-Based Medical Schools, Jessica Sobolik

Theses and Dissertations

It’s surprising that in the 50 years since computer networks were created, geographically distributed teams still face communication challenges. Businesses manage geographically distributed teams across the globe seemingly well, but in higher education, communication between geographically distributed teams on different campuses is a challenge. Faculty-administrators, staff and students are focused on their day-to-day tasks, and send e-mails and voicemails without giving much thought to how those messages are received on the other end. Often, the recipient of that communication reacts negatively, causing conflict.

This mixed-methods exploratory-sequential study qualitatively explored communication challenges, solutions, preferences, and feelings of connectedness and conflict among …

Cameroonian Immigrants Switching From Non-Stem To Stem-And-Related Fields In The United States, Delphine Ngum Tamukong

Theses and Dissertations

Recent studies on STEM education in the United States (U.S.) have largely focused on such issues as the ever increasing need for more STEM workers, STEM attrition/retention, the gender gap in STEM, encouraging more STEM enrollment both at college and post-graduate levels, and the use of modern technology to facilitate STEM education. Other studies have considered the impact of immigrants on STEM education in the U.S. and on the U.S. economy in terms of either creating or filling STEM jobs. Many of those studies underscore the importance of immigrants in boosting the high skilled, much needed, STEM labor force and …

Healthcare Providers’ Perceptions Of Barriers And Facilitators To Making A Recommendation To Screen For Colorectal Cancer, Jesse Tran

Theses and Dissertations

Background. Colorectal cancer (CRC) is the third most commonly diagnosed type of cancer in North Dakota. It also ranks second in late-stage diagnosis among all cancers. High quality screening tests such as colonoscopy have shown to reduce CRC incidence significantly, but screening rates in North Dakota remain low. The literature is consistent in that a recommendation by a healthcare provider is the most influential factor in a patient’s decision to screen.

Purpose. The purpose of this dissertation was to understand how healthcare providers perceive the barriers and facilitators that affect their decision to make CRC screening recommendations to patients. Identifying …

Characterization Of The Immune Stimulating Properties Of Type Iii Secretion System Needle Protein Bscf From Bordetella Pertussis: Towards The Development Of A New Acellular Pertussis Vaccine, Travis Douglas Alvine

Theses and Dissertations

Despite widespread vaccination, Bordetella pertussis, the causative agent of whooping cough, is still a threat to global health. One cause of pertussis reemergence observed in many countries is ineffective immunity generated by the current acellular pertussis (aP) vaccines. Interestingly, recent studies have shown that TLR stimulating agents can enhance aP vaccine induced immunity. Type III secretion (T3S) system needle proteins from many gram-negative bacteria have been shown to be strong TLR agonists that induce NF-B/AP-1 signaling and promote inflammatory cytokine release from innate cells in vitro. In this study, we investigated the immune modulating properties of BscF, a purified T3S …

An Evaluation Of Elk Home Range Variation In North Dakota, Jacqueline Marie Amor

Theses and Dissertations

In North Dakota, dispersing elk (Cervus elaphus) were colonizing areas of suitable habitat in Turtle Mountain, Pembina Hills, and Porcupine Hills, ND, USA. Although these 3 elk herds were small (~100–250 individuals each), they had been responsible for crop depredation in these areas. The North Dakota Game and Fish Department (NDGF) had little information on these elk herds. In cooperation with Standing Rock Sioux Reservation and Manitoba Department of Sustainable Development, NDGF contracted with the University of North Dakota (UND) to collect and analyze critical baseline information to better manage these elk herds. The objectives of this study were to …

The Prediction Of Nonmedical Prescription Stimulant Use In College Students, Danielle Lynn Beyer

Theses and Dissertations

The use of prescription stimulant medications, such as Ritalin and Adderall, has increased dramatically over the past two decades (Zuvekas & Vitiello, 2014). Particularly concerning to public health officials has been the escalation of college students who report nonmedical prescription stimulant use (NPS). Studies have identified cognitive enhancement (i.e., increased concentration, etc.) as the primary motive for college students to engage in NPS (DeSantis et al, 2011; Smith & Farah, 2011). Additional findings suggest individuals involved with Greek organizations and/or individuals who maintain lower cumulative grade point averages (GPA) report significantly higher rates of NPS than Non-Greek and/or higher GPA …

A Phenomenological Study Of Bullying Experienced By Graduate Students And Faculty Through The Lens Of Power, Anne Bodensteiner

Theses and Dissertations

The purpose of this study was to explore the lived experiences of graduate students and faculty members who experienced bullying as a result of their role in higher education. Phenomenological exploration of this topic involved interviews with 14 participants; seven graduate students and seven faculty members. Power as described by Foucault (1994) was used as theoretical framework for this research. Findings from the study revealed institutions of higher education exploit power through differentiation, institutionalization, instrumental modes, types of objectives, and rationalization. Age, gender, life experiences, and positional rank were differentials found between the subject and aggressor. Institutionalization was expressed through …

Intergenerational Effects Of Embryonic Cocaine Exposure In Zebrafish, Cody Adam Boyle

Theses and Dissertations

Cocaine addiction has both genetic and environmentally driven components. Relatively recently several groups have suggested that epigenetic regulation of gene expression might be the mechanism linking environmental influence and inheritance in drug addiction. We have shown previously that embryonic cocaine exposure increases physiological and behavioral sensitivity to the drug in longitudinal adults. In this study, we provide evidence that the effects of embryonic pre-exposure to cocaine are intergenerational in zebrafish. In addition, we show how gene expression in the zebrafish telencephalon, which includes the teleost equivalent of the nucleus accumbens, changes during acute cocaine treatment during behavioral testing. These experiments …

Health And Wellness Coaching Utilization And Perspectives Of Health Practitioners Working In American Indian Communities, Jill Breyen

Theses and Dissertations

Despite increased interest in client-directed counseling methods to manage chronic disease, limited data exists about utilization of counseling skills and attitudes towards these methods among health care providers, specifically those providing care to at risk populations. The aim of this qualitative study was to explore the beliefs and practices of a multidisciplinary group of health practitioners who were trained in health and wellness coaching (HWC) that included motivational interviewing (MI) techniques. The training was sponsored by the Bemidji Area Indian Health Service Health Promotion Disease Prevention (BAO IHS HPDP) program. Forty-seven trained coaches from the BAO IHS HPDP working with …

Acetate Supplementation Reduces Disease Progression, Alters Cns And Myelin Lipid Content, And Influences Cns And Myelin Protein Content In Mice Subjected To Experimental Autoimmune Encephalomyelitis, Amber C. Chevalier

Theses and Dissertations

Acetate supplementation increases brain acetyl-CoA levels that influence inflammation, energy production, histone and non-histone protein acetylation, and purinergic signaling. Interestingly, acetate significantly increases fatty acid content in lipopolysaccharide (LPS)-stimulated BV2 (immortalized murine cell line) microglia compared to control-treated LPS-stimulated cells. This suggests that increasing brain acetyl-CoA metabolism may also influence lipid synthesis. We wanted to determine if treatment with glyceryl triacetate alters central nervous system (CNS) lipid content in mice subjected to experimental autoimmune encephalomyelitis (EAE), an autoimmune multiple sclerosis model. In addition, we performed experiments to determine whether treatment had an effect on disease progression, protein levels of enzymes …

Investigating Cloud Condensation Nuclei Activity And Particle Growth Of Aging Diesel Exhaust Particles, Humphrey Chigozie Chukwuto

Theses and Dissertations

Soot particles are an essential atmospheric constituent because of their effects on human

health, regional and global climate. The impact of soot on climate and human health depends on

their ability to interact with water vapor. Freshly emitted soot particles are hydrophobic but the

chemical and physical transformations (aging) they undergo while airborne can make them hydrophilic

enough to retain water and act as nuclei for cloud formation. The aging of soot is a

complicated process and represents a significant uncertainty in quantifying the net radiative forcing

of soot particles. In this study, the cloud condensation nuclei (CCN) activity and …

Concurrent Plyometric And Endurance Training Effects On Aerobic Fitness-Performance In Adult Endurance Athletes: A Systematic Review With Meta-Analysis, Lisa Annemarie Connelly

Theses and Dissertations

Numerous training modalities have been used to improve aerobic fitness and performance. Concurrent strength and endurance training is considered an effective modality to improve aerobic outcomes, although little is known about the effectiveness of concurrent plyometric (jump) training. The aim of this systematic review and meta-analysis was to determine the effectiveness of plyometric training on aerobic fitness (operationalized as maximal oxygen uptake [V ̇O2max] and running economy [RE]) and performance (time trial performance). Five online databases were used to identify peer-reviewed studies published from 1980 onwards — the year the first concurrent training study was published. Studies were included if …

Relationships Between The Second To Fourth Digit Ratio (2d:4d) And Game-Related Statistics In Semi-Professional Female Basketball Players, Makailah Janae Dyer

Theses and Dissertations

Digit ratio (2D:4D) is a negative correlate of sports performance, although this relationship may be weak in open-skill sports. This study aimed to quantify relationships between 2D:4D and game-related statistics in female basketball players, and to quantify differences in mean 2D:4Ds between starters and reserves. Sixty-four female basketball players were measured for height, mass, and 2D:4D, with game-related statistics collected end-season. Partial correlations (adjusted for age and BMI) quantified relationships between 2D:4Ds and game- related statistics. Unpaired t-tests quantified differences in mean 2D:4Ds between starters and reserves. This study found that 2D:4D was a substantial negative correlate of blocks, rebounds, …

A Comparison Study Of American Indian And Caucasian Sex Offenders On Trauma And Selected Trauma Effects, Regina Sioux Ertz

Theses and Dissertations

American Indian/Alaskan Natives (AI/AN) have a long history of documented trauma experiences. In addition, AI/AN individuals are likely to have fewer economic resources and are faced with increased traumatic experiences in comparison to the general population. Further, the American Indian population is also affected by overrepresentation with incarceration rates in federal and state government detention centers. These data support the need to address non-sexual recidivism issues in the American Indian population. Little research has examined trauma experiences, selected trauma effects, and unique differences for American Indian sex offenders. Treatment employed for American Indian sex offenders is conducted based on data …

Design And Construction Of A Robotic Vehicle To Assist During Planetary Surface Operations, Christopher Anthony Follette

Theses and Dissertations

In the near future, astronauts will explore new planetary surfaces in the Solar System. To enable peak performance, these astronauts will need to utilize all of the tools at their disposal. It is proposed that one such tool is a planetary surface rover designed specifically to assist the astronauts during their Extra-Vehicular-Activities (EVA’s).

This rover is designed and built to operate in concert with existing analog planetary surface infrastructure at the University of North Dakota (UND). This rover will be remotely controlled by an astronaut located on the planetary surface, enabling real-time operation and obstacle avoidance. The rover will act …

An Investigation Of The Latent Structure Of Eating Disorder Behaviors And Non-Suicidal Self-Injury (Nssi), Erica Goodman Goodman

Theses and Dissertations

Non-suicidal self-injury (NSSI; deliberate harm to the self) and eating disorders frequently co-occur, and both place an individual at increased risk for suicide. Individuals who report NSSI are similar to those that report eating disorder behaviors on emotion regulation, impulsivity, and pain tolerance. Thus, the current study aimed to investigate how the relationship between NSSI and eating disorder behaviors is best understood, based on the intent of the behavior (e.g., “to hurt myself”) or the function (e.g., “I became less angry”). Participants were 493 undergraduate students (80% female; 90% white) who completed an online survey regarding lifetime NSSI and eating …

Development And Validation Of The Internalized Classism Scale For Poor And Working Class In The United States, Aleska Randa Hagan

Theses and Dissertations

The poor and working class are largely overlooked or ignored across many aspects of U.S society including public policy, societal structure, representation in media, and even in the realm of psychological research (Lott, 2002; Smith, 2005). Furthermore, of the scanty representations and descriptions of the poor and working class that are available, most are derived from oppressive classist views and negative stereotypes (Smith, 2010). Classism pervades the social structure of the United States. Classist beliefs and experiences of classism are internalized by all members of society to some degree. Working class and poor people who experience internalized classism are likely …

Special And General Education Partners Co-Teaching Through The Structural Lens Of Complexity Theory, Shirley Ann Johnson

Theses and Dissertations

Inclusive education is one of the most complex and demanding reforms in schools today. How school systems are structured may account for the many difficulties schools are having in strengthening, sustaining, and expanding inclusive education. Co-teaching is an instructional delivery method that offers a promising practice towards successful inclusive education. The purpose of this phenomenological study was to examine the perspectives of co-teachers actively engaged in expanding the practice of co-teaching to help leaders strengthen, sustain, and expand effective inclusive education for students with disabilities.

Complexity theory provided the theoretical framework to explore how the co-teachers interacted and self-organized when …

A Longitudinal Study Of The Negative Impact Of Falls On Health, Well-Being, And Survival Among Older Adults: An Examination Of Protective Psychosocial Mediators, Harpa Lind Jonsdottir

Theses and Dissertations

Falls can have detrimental effects on older adults’ physical and psychological health, and survival rates. However, there appears to be a protective psychosocial mediator that may lessen the negative impact of experiencing a fall on health and well-being. The psychosocial factors examined as mediators of the falls - health and well-being relationship in this study were dispositional optimism and perceived control. Participants were 232 community-dwelling older adults, age 68 or older. This study was linked to a longitudinal study including data collected in 2008 and 2010 (Grand Cities Healthy Aging Study (GCHAS). Measurements of dispositional optimism, perceived control, self-rated physical …

Social And Emotional Learning In The Ell Classroom: A Case Study, Satoko Takeda Kao

Theses and Dissertations

The goal of social-emotional learning (SEL) is to create a safe environment for students to learn in and improve peer relationships, decrease conduct problems and emotional distress, and promote academic achievement. SEL program implementation has grown over the last decade in U.S. schools; however, these programs are designed for general education, not English Language Learner (ELL) students. Furthermore, research on teaching SEL to ELL students is limited.

This study explored what SEL looked like and how bullying prevention and character education programs were adapted in an elementary ELL classroom. The theoretical framework for this study was based on CASEL’s “Five …

Genetic Analysis Of Frost Tolerance In Rapeseed/Canola (Brassica Napus L.), Danielle Fiebelkorn Wrucke

Plant Sciences

Frost can be detrimental to canola (Brassica napus L.) production. Depending on the severity, the entire field can be killed. Having frost tolerance in canola would benefit growers by allowing them to plant early, utilize early season moisture, and avoid high heat during flowering. However, frost tolerance in canola has not been well studied. A protocol was developed that determined 14 day old seedlings should be acclimated at 4°C for 7 days before being exposed to overnight frost (-4°C) in a small freezing chamber. However, when a larger chamber was used for freezing, the protocol was optimized to -8°C instead. …

Distillers Byproduct Compared To Other Nitrogen Sources As A Fertilizer For Corn, Elizabeth Anne Lovering

Plant Sciences

Corn (Zea mays L.) based ethanol and associated byproducts like wet (WDG) production has increased over the past decade. Research was conducted in five environments in North Dakota to determine the nitrogen (N) fertilization value of WDG compared to five other N fertilizer sources. In fertilizer responsive sites, 25% more WDG were required based on N equivalent than other N sources to obtain a similar yield and grain protein when applied in the spring. Effectiveness of WDG were reduced when applied to no-tilled corn. Utilizing WDG as a nitrogen source is not economical at the current product prices of WDG …

Hop Establishment Impacted By Mulch Type And Nitrogen Source, Lindsey Ranee Forward

Plant Sciences

Agronomic research is lacking for hops (Humulus lupulus), especially in North Dakota (ND) and the northern Great Plains, where demand has risen. This research was done to evaluate factors influencing hops establishment in ND. Factors for this research were hop cultivar, mulch type, and nitrogen source. Variables measured included weed suppression, soil temperature, soil moisture, hop growth, and yield. Nitrogen source did not affect hop growth. ‘Cascade’ outperformed ‘Mt. Hood’ and ‘Santiam’. Mulch type affected hop establishment, weed suppression, soil temperature, and soil moisture readings. Landscape fabric provided the greatest weed suppression and retained the most soil moisture, but also …

Dispute Resolution And Spiritual Congruity, F. Peter Philips

Articles & Chapters

A survey of various conflict resolution approaches suggests a correlation between spiritual traditions and conflict resolution strategies. Moreover, Western societies' approaches to dispute resolution appear incongruent with stated spiritual and cultural values.
