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 …

Feasibility Of Downscaling Naaps Aerosol Fields For Incorporating More Realistic Aerosol Direct Effects In Wrf-Chem Simulations, Brittany Nikole Carson

Theses and Dissertations

When unaccounted for in numerical weather prediction (NWP) models, heavy aerosol events can cause significant unrealized biases in forecasted meteorological parameters such as surface temperature. A novel concept is proposed in this study to dynamically downscale aerosol fields from a global chemical transport model into a higher resolution NWP model to improve the near-surface forecasting accuracies during heavy aerosol events like biomass burning events. This concept is tested for a major biomass burning aerosol event over the Northern Great Plains region of the United States that occurred from 28 June – 4 July 2015. Aerosol analyses from the Navy Aerosol …

Simulation Of Notch Driven Hydraulic Fracture In Open Hole Completion, Nejma Djabelkhir

Theses and Dissertations

Hydrocarbon production from unconventional plays, including shale oil and gas, has begun in the USA since nearly two decades ago and experienced a rapid growth. Horizontal drilling and multistage hydraulic fracturing (HF) are the prime technologies in development and stimulation of unconventional reservoirs. Open hole (OH) and cased hole (CH) are the primary completion methods used in unconventional reservoirs. OH compared to cased hole (CH) completion is more desired as it requires less operation cost and time while it results in more production due to larger area of wellbore exposure to the formation. However, OH completion is susceptible to near …

Sexism, Gender Identity, And Psychological Well-Being: Examining Women’S Reactions To A Social Identity Threat, Wendy Nicole Fisher

Theses and Dissertations

For women, sexism is an unavoidable experience and perceiving one’s self as a victim of sexism can have detrimental effects on psychological well-being. However, situational factors, such as level of sexism, and individual differences in gender-related beliefs can influence whether women attribute negative experiences and outcomes to sexism and the degree to which they are impacted by sexism. The current two-part study examined how women responded to sexist feedback depending on the level and target of sexism, as well as individual differences in gender identity and endorsement of sexism. The impact of sexist feedback on women’s psychological well-being was also …

The Value Of Existential Worlds: Creation And Validation Of A Measure To Explore The Four Existential Worlds, Matthew Robert Rozzi

Theses and Dissertations

The field of counseling psychology is increasingly focused on understanding clients in holistic and non-pathologizing ways. Existential theory provides the four-worlds model for exploring human existence in line with this modern psychological zeitgeist. In this model, humans are understood to exist simultaneously in four “worlds” or “dimensions”: physical (umwelt), social (mitwelt), psychological (eigenwelt), and spiritual/philosophical (uberwelt). This measure construction project is the first known study to examine the personal importance (value) of existing in each world. The Value of Existential Worlds (VEW) was created and psychometrically examined. From the initial 63-items, a shorter (20-item) version was created which demonstrated a …

Case Judgments And Juror Perceptions Of The Stereotypical Defendant, Mariah Sorby

Theses and Dissertations

Stereotypes and prejudice have been shown to bias information processing and decision making. There are physical traits that are stereotypically associated with criminals, i.e. tattoos, dark skin-tone, facial untrustworthiness, Afrocentric facial features. These features have been shown to influence verdict decisions and sentencing outcomes. However, there is a paucity of research investigating the additive effects of these features while also considering individual levels of prejudice and egalitarian views. The current research aimed to investigate the effects of several combinations of features on defendant verdict, sentencing, and criminal appearance ratings, rather than assessing the features in isolation, while controlling for prejudice …

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 …

Design Of Spouted Fluidized Bed Computational Models For Advanced Energy Applications, Ryder Shallbetter

Theses and Dissertations

Fluidization process technology has been widely studied since its first commercial uses during the 1920s. Initially, developmental progress was slow as fluidized beds are complex in design and often hard to scale up in size. However, with the emergence of computational fluid dynamics (CFD), researchers were able to simulate wide ranges of fluidization and create new fluidization designs to help solve complex problems. This study aims to determine if CFD can be effective in designing spout-fluid beds with draft tubes for advanced energy applications. CFD has been employed for studying the fluidization characteristics, design, and optimization of spouted beds. However, …

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 …

Stochastic Inversion Integrating Seismic Data, Litho-Facies Physical Properties, And Multiple-Point Geostatistics For Reservoir Characterization, Mohamed Mohamed

Dissertations, Master's Theses and Master's Reports

We proposed a novel seismic inversion approach that integrates the physical properties of litho-facies, and geophysical data, within the multiple-point geostatistical frameworks to reduce the uncertainty in predictions of litho-facies spatial arrangement away from wells or control points. The litho-facies groups (rock-type) in the well locations are defined and conditioned to the distribution of elastic properties, including P-wave velocity (Vp) and facies density (ρ) in the well locations. A conceptual geological model (training image) is utilized within a wavelet-based multiple-point geostatistical simulation (WAVESIM) algorithm to generate litho-facies realizations. In our inversion algorithm, the forward model is created by implementing the …
