Perceptions Of Consensual Sexual Student-Faculty Relationships, Olivia Pottschmidt

Theses and Dissertations

Consensual, sexual relationships (CSRs) involving university faculty members and students are not uncommon (Richards et al., 2014). Given the increased attention of sexual harassment on college campuses, a number of universities have implemented CSR policies that generally fall into three categories: total ban, limited ban, and discouragement. Despite the intention of these policies,--the prevention of sexual assault and harassment--they have been criticized for being vague and too general (Bellas & Gosset, 2001; Jafar, 2003). Examining student perceptions can provide inside into university culture and inform policymaking. To this end, participants were randomly assigned to one of four conditions stemming from …

Investigation Of Factors That Affect Site Selection For Geothermal Energy Extraction In North Dakota, Ogonna Obinwa

Theses and Dissertations

Geothermal energy is independent renewable energy extracted from deep and shallow subsurface to provide electricity and heat for many applications. At shallow depths of about 3000 feet (914 meters), temperatures as high as 70 degrees Celcius could be extracted and used for domestic and commercial heating systems. Deeper and hotter resources are usually available at depths greater than 10000 feet (3048 meters). The hotter the extracted fluid temperature, the better it is suited for electricity generation. New technologies such as binary cycle systems have made it possible to use moderately hot liquids for electricity generation. However, specific conditions must be …

Endolysosome Involvement In The Protective Effects Of 17Ơ-Estradiol Against Hiv-1 Protein-Induced Neuronal Injury, Nicole Miller

Theses and Dissertations

Although combined antiretroviral therapy (cART) effectively suppresses HIV-1 infection and increases the lifespan of people living with HIV, up to 50% of HIVinfected individuals are experiencing HIV-associated neurocognitive disorder (HAND), with clinical symptoms ranging from mild cognitive impairment to severe dementia, for which no effective treatment is currently available. Synaptodendritic impairments, such as decreased dendritic spines and synaptic loss, that occur in various brain regions including the prefrontal cortex and hippocampus are key pathological features of HAND that correlates closely with neurocognitive impairments. The development of synaptodendritic impairment in HAND in the post-cART era is complicated and not fully understood; …

Hydraulic Fracture Propagation And Its Geometry Evolvement In Transversely Isotropic Formations, Dezhi Qiu

Theses and Dissertations

During the last two decades, the oil and gas industry started production from unconventional reservoirs, thanks to the rapid development of hydraulic fracturing technology. Fractures such as joints, faults, veins, and bedding planes are ubiquitous in unconventional formations such as laminated reservoirs. These discontinuities always form complex networks affecting the hydrological and mechanical behavior of subsurface rocks. Ideally, hydraulic fractures are expected to communicate these fracture networks to form a continuous path for fluid flow. However, the interaction mechanism between hydraulic fracture and natural fractures may result in different propagation paths to form various fracture geometries and stimulated reservoir volume …

An Examination Of Rural Help-Seeking Behaviors Related To Sexual Violence And Mental Health And Well-Being Outcomes, Dacia Kay Oberhelman

Theses and Dissertations

Those who experience sexual violence face numerous barriers in gaining access to resources. Additionally, choosing to seek help following an unwanted sexual experience is a difficult decision that is impacted by attitudes, subjective norms, and perceived behavioral control. The Theory of Planned Behavior addresses how these variables can help explain one’s intent to seek help following an unwanted sexual experience. Seeking help following an unwanted sexual experience has also been suggested to be increasingly difficult for those in rural communities due to additional barriers such as: fear of community and family backlash, lack of anonymity, fear of perpetrator(s) discovering services …

Characerization, Depolymerization And Fractionation Of Alkali Lignin, Audrey Lynn Lavallie

Theses and Dissertations

Lignin may serve as a potential source of renewable chemicals and as a possible wealth of materials for replacement of petroleum-based fuel and petrochemicals. Lignin is a plant component that constitutes the second most common natural polymer on earth, behind only cellulose, and is the most common natural polymer with an aromatic network. Technical lignins (isolated from chemical processing of raw lignin) are produced as waste in the papermaking and biorefinery industries; an estimation of U.S. waste lignin is about 24 million tons yearly, more than the estimated 10.5 million tons of plastics discarded annually. The exact structures of natural …

Social Cognitive Well-Being Model With Native American Students: Exploring Racial Identity And Internalized Racial Oppression, Megan Kay Smith

Theses and Dissertations

In this study, Lent’s (2004) social cognitive model of well-being (SCWB) was employed to examine the academic and social domain of satisfaction and life satisfaction with 121 Native American college students. They completed measures of positive affect, Native American identity, internalized racial oppression, and life satisfaction along with domain-specific (i.e., academic and social) self-efficacy, goal progress, and satisfaction. Using path analytic techniques, results indicated that the academic SCWB model was a close fit to data and the social SCWB model was a good fit to data. For both models, the relations among constructs accounted for large portions of variance for …

Negative And Positive Attention Bias In Anhedonia And Anxious Arousal: Can Depression And Anxiety Be Distinguished By Patterns Of Engagement And Disengagement Bias?, Helen Sawaya

Theses and Dissertations

Negative and positive attention bias (AB) is the preferential allocation of attentional resources to negative and positive stimuli in the environment, respectively. AB has been studied in various clinical and non-clinical populations and the process has been linked to symptoms of depression and anxiety. Findings so far suggest that negative AB is a trait-based factor that predisposes individuals to anxiety and depression. Positive AB appears specific to a depressed state, yet findings generally remain mixed. Measures of AB have been recently critiqued for their poor psychometric properties. This study addresses three gaps in the literature to further our understanding of …

An Exploration Of Sexual Consent, Sexual Non-Consent, And Nonverbal Sexual Consent Communication Behaviors, Amongst Community Stakeholders., Brent Stewart

Theses and Dissertations

Sexual Consent is a central concept in the field sexual violence and sexual violence prevention (Beres, 2007). However, despite disproportional rates of sexual violence amongst LGBT+ community, currently our understanding sexual consent and its practice is primarily focused on heterosexual encounters of traditional college aged students (CDC, 2017, Muehlenhard, Humphreys, Jozkowski & Peterson, 2016). The current study utilized the Delphi method to develop a better understanding of sexual consent, sexual non-consent, and nonverbal sexual consent communication behaviors among two distinct groups: sexual researchers and men who have sex with men (MSM). Thirty-five panelists (13 researchers 22 MSM) completed one- three …

Snail As A Dual Dna/Rna Binding Transcription Factor, Smruthi Rudraraju

Theses and Dissertations

Transcription factors (TFs) are a class of proteins that recognize and bind to specific DNA sequences to regulate gene transcription. This process often involves the recruitment of other proteins, including chromatin remodelers and RNA polymerase. Because of their crucial role in gene expression, transcription factor activity is generally tightly controlled. Aberrant transcription factor activity has been implicated in the pathogenesis of most diseases. Techniques such as chromatin immunoprecipitation followed by sequencing have helped researchers determine which genomic sites are bound by TFs.Experimentally determined TF binding sites are much fewer than the total number of predicted DNA binding sites present in …

Synthesis Of A Gemini Monomer And Cyclobutane-Containing Bifunctional Building Blocks For Novel Materials, Rahul Kumar Shahni

Theses and Dissertations

Gemini monomer, a new monomeric class that consists of two monomeric units connected by a covalent linker, can offer a highly dense polymeric framework. Moreover, their ability to form twice the number of covalent bonds than the conventional monomer can afford polymers with high thermal and mechanical strength. The desired Gemini monomer, ethylene 1,2-bis (2,4-pentadienoate) (EBP), was synthesized in two steps. First, an acid precursor 2,4-pentadienoic acid was synthesized by the condensation of malonic acid and acrolein. Second, ethylene glycol was used to connect two 2,4-pentadienoic acid units to obtain the monomer. Later, EBP was polymerized in ambient and solvent-free …

Transcriptomic And Pharmacological Characterization Of A Murine Line Harboring An Antidepressant-Insensitive Serotonin Transporter, Meghan Alicia Rodriquez

Theses and Dissertations

Perinatal depression is a complex mood disorder often treated with Selective Serotonin Reuptake Inhibitor (SSRI) antidepressants, which block the serotonin transporter (SERT) and alter synaptic serotonin concentrations. The serotonergic system is highly plastic and serotonin regulates the growth and maturation of neurons and signaling systems from conception through end of life. Notably, interference with serotonin levels during an SSRI sensitive window (SSW) of development in humans and rodents has been linked to neurovegetative effects which increase susceptibility for the manifestation of anxiety- and depressive-like behaviors and can be persistent throughout life. We hypothesize the persistent behavioral perturbations resulting from acute …

The Death Of The Big Deal And Implications For Technical Services, Angela Maranville, Karen Diaz

Faculty & Staff Scholarship

In recent years, a growing number of libraries have canceled or unbundled their “Big Deal” journal subscriptions – those subscriptions that include a full package of digital journal titles for one discounted cost. This started as an affordability problem but has slowly morphed into a challenge from libraries demanding a new pricing structure that accommodates and spurs the growing open access movement.

The change has caused a variety of challenges for technical services units including the increased need for user data, increasingly complicated workflows as they manage partial subscriptions, new interactions with consortia, and ongoing campus conversations. Whether the library …

Riparian Vegetation Changes Along The Red River Of The North: 1997-2018, Laura Akindo

Theses and Dissertations

Riparian zones are areas along waterways that are typically covered by woody vegetation, herbaceous plants, and grasses. Flooding is an important process in riparian habitats as it continuously causes net gains and losses of substrates in riparian communities that determine the productivity of the riparian area. Most notably by providing new areas on the floodplain to be colonized by riparian plant species. Sometimes extreme flooding events can temporarily devastate riparian communities, as in most cases the area recovers quickly. This study evaluated the effects of the 1997 Red River flood on the woody cover in the riparian area cover along …

Development Of A Deep Neural Network Based Method For Quality Control Of Modis Maiac Aerosol Data For Aerosol Modeling Applications, Joel Braxton Aldridge

Theses and Dissertations

Quality-assured satellite aerosol data have been shown to improve aerosol analysis and forecasts in Chemical Transport Models. However, biases present in the satellite-based aerosol data can also introduce non-negligible uncertainties in the downstream aerosol forecasts and impact model forecast accuracy. Therefore, in this study we evaluated uncertainties in Moderate Imaging Spectroradiometer (MODIS) Multi-Angle Implementation of Atmospheric Correction (MAIAC) aerosol products and developed a deep neural network (DNN) based method for quality control of Terra and Aqua MODIS MAIAC Aerosol Optical Depth (AOD) data using the version 3 level 2 AErosol RObotic NETwork (AERONET) data as the ground truth. This method …

Transcriptomic Analysis Of Young Regenerating Magnocellular Neurons (Mcns) Vs Mature Non- Regenerating Mcns, Malak Alzidaneen

Theses and Dissertations

Mature mammalian CNS neurons do not regenerate or recover following injuries. Different transcription factors have been linked to axonal growth and survival, and regulation changes in these transcription factors will affect the expression levels of genes involved in axonal regeneration. A robust collateral sprouting response within the distant terminal field of magnocellular neurons, the neurohypophysis, arising from the contralateral non-injured supraoptic neurons have been shown in response to unilateral denervation of MCNs tracts. This response peaked at age 35 days then it was followed by a complete loss of the regenerative capacity between 35 days and 125 days of age. …

Understanding Decision-Making Styles Of Part 135 Pilots In Remote Settings And Their Impact On Aviation Safety: A Qualitative Enquiry Of Alaskan Operational Environments, Dana Atkins

Theses and Dissertations

Aviation is a vital component of the State of Alaska’s transportation system. Air transportation is frequently the only means to move goods, services, and people across the state. Historically, air taxi and non-scheduled/charter air operators (14 C.F.R. Part 135) form the bulk of service providers in Alaska and have poor operational safety records through high rates of accidents. The problem is still prevalent despite numerous initiatives by the Federal Aviation Administration to reduce adverse safety events. Accident investigation reports have nominally attributed causal factors of these accidents to pilot error and at-risk behaviors such as violations. Extant research in aviation …

The Transformation Of Teacher Education Using Three-Dimensional Science Instruction, Patricia Ann Arnold

Theses and Dissertations

The impact of the Next Generation Science Standards (NGSS) on K-12 science education has gained significant momentum over the last several years. Evidence of the NGSS can be seen in revised state science content standards and amended teacher preparation standards. Due to this growing impetus, a holistic redesign of teacher preparation to systemically implement three-dimensional science teaching and learning needs to be prioritized. Based on this premise, this study investigated the change in pre-service teachers’ perceived self-efficacy in teaching science using three-dimensional instruction upon completion of an NGSS-designed intervention incorporated into an introductory science methods course. Designed as a “working …

Open And Fair Skies: A Level Playing Field For American Workers, Shea Byom

Theses and Dissertations

For years Delta, American, and United airlines have cited unfair practices by Qatar,United Arab Emirates, and Etihad airways. The main problem, they argued, was the unfair business practices, especially the government subsidies provided to these Gulf carriers that they believed harmed competition, and put at risk millions of U.S. jobs supported by tourism and travel (Al-Sayeh, 2014). Delta, American, and United airlines believed that the Gulf carriers were in direct violation of their Open Skies agreement, which provides open competition between all airlines. “Fair and open” eliminates government interference in commercial decisions of air carriers about routes, capacity, and pricing …
