“What’S Belonging Got To Do With It?”: An Exploration Of Campus Racial Climate And Sense Of Belonging In Black Counseling Students Attending Predominately White Institutions In The North Atlantic Region, Erin Durrah

Graduate Theses and Dissertations

Diversity, equity, and inclusion (DEI) dialogues are raging across campuses throughout the U.S. with specific focus on the needs of Black student populations in the aftermath of the George Floyd, Breonna Taylor and Ahmaud Arbury murders. However, if the supportive spirit of the DEI initiatives is undermined by a hostile campus climate and local community, it may negatively impact the learning environment isolating the target population, while also effecting their potential for successful completion of their programs. The current qualitative study aims to explore the perceptions of belonging expressed by Black graduate students enrolled in Council for Accreditation of Counseling …

Differential Impacts Of Hhv-6a Versus Hhv-6b Infection In Differentiated Human Neural Stem Cells, Elham Bahramian

Graduate Theses and Dissertations

Within the family Herpesviridae, sub-family β-herpesvirinae, and genus Roseolovirus, there areonly three human herpesviruses that have been described: HHV-6A, HHV-6B, and HHV-7. Initially, HHV-6A and HHV-6B were considered as two variants of the same virus (i.e., HHV6). Despite high overall genetic sequence identity (~90%), HHV-6A and HHV-6B are now recognized as two distinct viruses. Sequence divergence (e.g., >30%) in key coding regions and significant differences in physiological and biochemical profiles (e.g., use of different receptors for viral entry) underscores the conclusion that HHV-6A and HHV-6B are distinct viruses of the β-herpesvirinae. Despite these viruses being implicated as causative agents in …

Understanding Perceptions Of Graduating Seniors From Rural Schools On Higher Education: A Preregistered Study, Desiree Denise Brake

Graduate Theses and Dissertations

The purpose of this qualitative case (preregistered) study is to interview rural young Americans, deeply explore how they think about higher education as they prepare for life beyond high school, and analyze how those views and perceptions translate into barriers or motivators to its pursuit. Rural Americans feel less optimistic about their financial futures, find it more difficult to find a job in their communities, and believe their children will have a lower standard of living than their parents when they reach their parents’ age (Morin, 2016). Rural students are more likely to graduate from high school than their urban …

Female Adults’ Experiences Of Sexual Harassment And Assault In The Presence Of Others: A Qualitative Analysis Of The Effectiveness And Consequences Of Bystander Intervention Strategies, Kayla Ford

Graduate Theses and Dissertations

Bystander intervention programs aim to reduce the acceptance of violence against women by fostering prosocial behavior from community members, and often provide knowledge on behaviors associated with sexual risk and ways a bystander can intervene. However, there is limited knowledge on which intervention strategies are used, and how these interventions impact perpetrator behavior and incidence of verbal and physical harm to those involved. There is even less research on these phenomena from the perspective of the victim. To address these gaps, the current study utilized a qualitative approach to (1) identify bystander intervention strategies employed; (2) discuss trends of the …

Graduate Theses and Dissertations

This qualitative case study examined the impact Situational Leadership Theory II® has on followers in a small community in Haiti. Many studies have examined Situational Leadership Theory II® in corporate environments, but not in the low-income context of Haiti. The study focused on how the leadership characteristics and adaptability levels of an expatriate influenced the construction and the ongoing management of a Haiti egg farm project, which is timely based on the volatility currently in the country prior to and after the assassination of President Jovenel Moïse in 2021. Using various data gathering instruments, the study explored the expatriate’s leadership …

Investigating How Facilitators View The Functions And Perceived Values Of Reflective Activities On Transformative Learning Amongst People In Addiction, James Ryan Eller

Graduate Theses and Dissertations

Although there has been considerable empirical support for the effect of reflection, and specifically reflective activities, within the domain of transformative learning (Ballon & Skinner, 2008; King, 2004; Mezirow, 2012; Roessger, 2014; Taylor, 2017), there is a gap in the literature concerning the value of formal reflective activities when used with people in addiction recovery programs. I will interview facilitators of addiction programs to inquire on the methods of reflection their programming provides people in addiction, investigate the effectiveness of the activities, and then determine the connections (if any) between formal reflective activities and transformation in people in addiction. This …

Reliability Enhancing Control Algorithms For Two-Stage Grid-Tied Inverters, Yuheng Wu

Graduate Theses and Dissertations

In the photovoltaic (PV) generation system, two types of grid-tied inverter systems are usually deployed: the single-stage grid-tied inverter system and the two-stage grid-tied inverter system. In the single-stage grid-tied inverter system, the input of the inverter is directly connected to the PV arrays, while an additional dc-dc stage is inserted between the PV arrays and the dc-ac inverter in the two-stage design. The additional dc-dc stage could provide a stable dc-link voltage to the inverter, which also enables new design possibilities, including the multi-MPPT operation and solar-plus-storage application. Thus, the two-stage grid-tied inverter has been widely used in the …

Micronutrient Concentration Effects On Lettuce Growth And Susceptibility To Pythium, Kalyn M. Helms

Graduate Theses and Dissertations

In hydroponic production waterborne pathogens such as Pythium are ubiquitous and continually threaten a wide range of Controlled Environment Agriculture (CEA) crops in hydroponic production, including but not limited to: lettuce, spinach, basil, arugula, cucumber, tomato, sweet pepper, roses, chrysanthemums, and cannabis (Sutton et al., 2006; Gull, 2002; McGehee and Raudales, 2021; Gillespie, 2020). Despite extensive sanitation measures, disease control in hydroponics is fallible and requires constant surveillance and management to minimize outbreaks (Sutton et al., 2006). A potential disease suppression strategy is to increase micronutrient concentrations within hydroponic systems to naturally strengthen plant defenses against pathogens such as Pythium. …

The Impact Of Video-Taped Social Modeling On Alcohol Outcome Expectancies Of Young Adults And The Role Of Social Anxiety, Kyle Kevin Jackson

Graduate Theses and Dissertations

Alcohol outcome expectancies (AOEs) represent people’s ideas about the effects of alcohol (Fromme, 1993). Positive AOEs particularly have been identified as a potential risk factor for hazardous drinking (e.g., Brown et al., 1985). The exact mechanisms that modify AOEs are not fully understood. Further, people higher in social anxiety may be especially receptive to social modeling due to attentional bias shift towards others in social contexts (Rapee & Heimberg, 1997). The current study examined how social anxiety and social modeling associate with AOEs. It was hypothesized that 1) those in the social modeling treatment condition would have higher social anxiety-adjacent …

Using Copper Oxide And Zwitterions To Prevent Membrane Fouling And Optimizing Ultrafiltration Membrane Fabrication With Green Solvents, Cannon Hackett

Graduate Theses and Dissertations

Membrane fouling and sustainable production of membranes are two of the most important challenges in membrane science. Chapter 1 of this dissertation introduces these challenges and covers previous research that has been done in those areas. Additionally, the objectives of this dissertation are stated. In chapter 2, a study was done in which polyethersulfone ultrafiltration membranes were functionalized with copper oxide nanoparticles and zwitterions for the purpose of reducing fouling on the membrane surface. Characterization confirmed the attachment of each component to the membranes. Dead-end filtration was performed with water and bovine serum albumin solution and showed that the functionalization …

Multivariate Fairness For Paper Selection, Reem Alsaffar

Graduate Theses and Dissertations

Peer review is the process by which publishers select the best publications for inclusion in a journal or a conference. Bias in the peer review process can impact which papers are selected for inclusion in conferences and journals. Although often implicit, race, gender and other demographics can prevent members of underrepresented groups from presenting at major conferences. To try to avoid bias, many conferences use a double-blind review process to increase fairness during reviewing. However, recent studies argue that the bias has not been removed completely. Our research focuses on developing fair algorithms that correct for these biases and select …

Refugee-Background Students In New Zealand And The United States: Roots And Results Of Educational Policies And Practices, Jody L. Mcbrien, Maria Hayward

Journal of Global Education and Research

Both the United States (US) and New Zealand (NZ) have been resettling refugees since the Second World War. As such, and because of several international treaties signed by both countries, they must concern themselves with the education of resettled refugee students in their nations. In this study, the researchers examine the international agreements and national resettlement policies that shape these nations’ refugee education policies. Second, educational practices for refugee students in the US and NZ using phenomenological qualitative research based on observations, interviews, and focus groups with teachers and refugee students are examined. The researchers conclude that the more systematic …

Distress In The Workplace: Characterizing The Relationship Of Burnout Measures To The Occupational Depression Inventory, Irvin Sam Schonfeld, Renzo Bianchi

Publications and Research

Burnout has been found to problematically overlap with depression. However, the generalizability of this finding remains disputed. This study examined burnout–depression overlap using the recently developed Occupational Depression Inventory (ODI) and two burnout measures, the Maslach Burnout Inventory (MBI) and the Copenhagen Burnout Inventory (CBI). The study involved two teacher samples employed in France (N = 1,450) and New Zealand (N = 492). We found the correlations of the ODI with (a) the MBI’s emotional exhaustion (EE) subscale and (b) the CBI to reach .80. An explanation of these high correlations based on content overlap in fatigue-related items was ruled …

Impacts Of Feeding Biochar To Beef Cattle On Greenhouse Gas Emissions And Performance And Characterizing Yearling Steers Grazing Smooth Bromegrass Pasture Using Gps, Holly A. Heil

Department of Animal Science: Dissertations, Theses, and Student Research

As global warming continues to rise, the pressure and growing demand for sustainable animal production is increasing. Livestock naturally produce greenhouse gas emissions through enteric fermentation. Dietary manipulation strategies have been sought out to decrease emissions in ruminants using feed additives.

Two independent finishing feedlot experiments evaluated two types of biochar and its effects on animal performance, carcass characteristics and greenhouse gas emissions. Experiment 1 utilized pistachio shell biochar and experiment 2 utilized biochar sourced from ponderosa pine wood waste, both types included at 1% of the diet DM. The addition of biochar to the diet did not impact animal …

The Nebraska 4-H Equine Advancement Level Program’S Role In Positive Youth Development Using The Five Cs Model: An Exploratory Study, Eunhye Mccarthy

Department of Animal Science: Dissertations, Theses, and Student Research

Positive youth development (PYD) focuses on developing the strengths of youth through positive activities and behaviors rather than reducing negative tendencies. A well-researched model of PYD is the five C’s model that is popularly used in youth development organizations such as 4-H. The Nebraska 4-H Equine Advancement Level program was intended to serve as a guidebook for instruction and assessment of youth as they learn more about horses and horsemanship skills. Each of the four levels has an emphasis in developing a 4-H member’s responsibility, self-discipline, self-reliance, patience, and pride of accomplishments. The program was started approximately 30 years ago …

Variance Component Estimates For Growth Traits In Beef Cattle Using Selected Variants From Imputed Low-Pass Sequence Data, Chad A. Russell

Department of Animal Science: Dissertations, Theses, and Student Research

A beef cattle population (n = 2,343) was used to assess the impact of variants identified from imputed low-pass sequence (LPS) on the estimation of variance components and genetic parameters of birth weight (BWT) and post weaning gain (PWG). Variants were selected based on functional impact and were partitioned into four groups (Low, Modifier, Moderate, High) based on predicted functional consequences and re-partitioned based on consequence of mutation, such as missense and untranslated region variants, into six groups (G1-G6). Each subset was used to construct a genomic relationship matrix (GRM) for univariate animal models. Multiple analyses were conducted to …

Environmental Determination Of Gastrointestinal Parasitism In Katahdin Sheep, Brian Arisman

Department of Animal Science: Dissertations, Theses, and Student Research

Gastrointestinal nematodes (GIN) negatively affect the performance and wellbeing of sheep and are difficult to control due to anthelmintic resistance. Producers are therefore choosing breeds naturally resistant to GIN infection, such as the Katahdin. Katahdin are raised in various climates and management systems in the U.S., and those environmental factors can be combined into eco-management clusters. We hypothesized that GIN challenge varies predictably based on the characteristics of these clusters. Katahdin producers from across the U.S. were surveyed for management information. Body weights (BW), fecal egg counts (FEC) and FAMACHA scores (FAM) were collected on 3,527 Katahdin lambs around 90 …

Polygenic Transcriptome Risk Scores (Ptrs) Can Improve Portability Of Polygenic Risk Scores Across Ancestries, Yanyu Liang, Milton Pividori, Ani Manichaikul, Abraham A. Palmer, Nancy J. Cox, Heather E. Wheeler, Hae Kyung Im

Biology: Faculty Publications and Other Works

Background: Polygenic risk scores (PRS) are valuable to translate the results of genome-wide association studies (GWAS) into clinical practice. To date, most GWAS have been based on individuals of European-ancestry leading to poor performance in populations of non-European ancestry. Results: We introduce the polygenic transcriptome risk score (PTRS), which is based on predicted transcript levels (rather than SNPs), and explore the portability of PTRS across populations using UK Biobank data. Conclusions: We show that PTRS has a significantly higher portability (Wilcoxon p=0.013) in the African-descent samples where the loss of performance is most acute with better performance than PRS when …

Biostatistics Collaborative Core: Faculty Publications and Other Works

Objective: We aimed to examine biomarkers for screening unhealthy alcohol use in the trauma setting.

Summary and Background Data: Self-report tools are the practice standard for screening unhealthy alcohol use; however, their collection suffers from recall bias and incomplete collection by staff.

Methods: We performed a multi-center prospective clinical study of 251 adult patients who arrived within 24 hours of injury with external validation in another 60 patients. The Alcohol Use Disorders Identification Test served as the reference standard. The following biomarkers were measured: (1) PEth; (2) ethyl glucuronide; (3) ethyl sulfate; (4) gammaglutamyl-transpeptidase; (5) carbohydrate deficient transferrin; and (6) …
