A Data Driven Approach To Optimize Re-Fracturing Operations In The Williston Basin, Joshua Kroschel
A Data Driven Approach To Optimize Re-Fracturing Operations In The Williston Basin, Joshua Kroschel
Theses and Dissertations
Because of the recent paradigm shift focusing heavily on cost minimization, many operators are now re-developing existing assets at much lower costs instead of developing newly drilled wells. Although it may seem that the hydraulic fracturing process on a well would be easier after initial stimulation, this is not usually the case and is often more difficult. Being able to identify high margin effects of treatment parameters will help engineers design hydraulic fracturing treatments to minimize average STP (STP) and minimize costs. This research develops a feature engineered multivariate regression model that identifies several high margin areas for STP reduction. …

Childhood Adversity And The Millon Clinical Multiaxial Inventory, Fourth Edition (Mcmi-Iv), Jenna Marie Wolff
Childhood Adversity And The Millon Clinical Multiaxial Inventory, Fourth Edition (Mcmi-Iv), Jenna Marie Wolff
Theses and Dissertations
The Millon Clinical Multiaxial Inventory, 4th edition (MCMI-IV; Millon et al., 2015) is a reliable and valid personality assessment based on Theodore Millon’s biosocial learning theory of personality. Millon’s theory evolved to include 15 personality constructs that vary in adaptive and maladaptive response patterns. In his most recent book (Millon, 2011), he presented hypotheses about biological and environmental factors that contribute to development of each personality construct. Many of these hypotheses specify particular adversities in childhood that differentially contribute to each construct. This study is the first to evaluate Millon’s hypotheses about how childhood adversities may contribute to development of …

Capital Trial Facets: Juror Perceptions Of Expert Testimony, Prior Record, And Mental Health, Madison Elizabeth Adrian
Capital Trial Facets: Juror Perceptions Of Expert Testimony, Prior Record, And Mental Health, Madison Elizabeth Adrian
Theses and Dissertations
Capital trials introduce several emotional components beyond what occurs within a typical trial. Furthermore, in cases where a defendant’s mental state has been called into question, there is additional layer of bias and stereotyping toward the defendant, particularly when diagnosed with schizophrenia or psychopathy. Additionally, expert testimony frequently enters the court as mitigating evidence to persuade jurors against the death penalty, yet prior research has found mixed results regarding which types of experts are most effective. On the other hand, prior criminal record may be utilized as an aggravating factor, yet its scope in differing crime contexts, such as a …

Understanding Nanog's Role During Cell Differentiation, Oluwatobiloba Samuel Aminu
Understanding Nanog's Role During Cell Differentiation, Oluwatobiloba Samuel Aminu
Theses and Dissertations
Pluripotency is characterized by the capacity to self-renew and differentiate into all cell types. This state relies on both extrinsic factors, such as leukemia inhibitory factor and bone morphogenetic protein, and intrinsic factors, including pluripotent transcription factors.While the role of pluripotent transcription factors in stem cell maintenance is well understood, their functions beyond pluripotency remain unclear. In this study, we focused on NANOG, a core member of the pluripotency network, and investigated its roles in two different models of differentiation: the transition from the naive to the primed pluripotent state and neuroectodermal differentiation. Our findings demonstrate that NANOG plays a …

The Interplay Between Parp-1 And Histone Modifications In Transcriptional Regulation During Development And Heat Shock Response, Gbolahan Gbenga Bamgbose
Theses and Dissertations
Poly(ADP-ribose) polymerase 1 (PARP-1), a multifunctional nuclear enzyme, plays a crucial role in transcriptional regulation through its three functional domains: the N-terminal DNA-binding domain (DBD), the automodification domain (AD), and the C-terminal domain, which includes the WGR and the catalytic domains. Despite its importance, the mechanisms directing PARP-1 to chromatin remain unclear and PARP-1’s role in development is still poorly understood. In chapter II, we interrogated the role of PARP-1 domains in PARP-1 to chromatin. We used ChIP-seq of YFP-tagged deletional isoforms of PARP-1 and a construct that lacks only the first zinc finger domain (ΔZnI). Interestingly, our findings suggest …

Intracranial Mast Cell Activation And Central Histaminergic Dysregulation In Food Allergy-Associated Neuropathology And Behavioral Changes, Danielle Germundson-Hermanson
Theses and Dissertations
Food allergy occurs when the immune system reacts inappropriately to an otherwise harmless food. The hypersensitivity response is known to cause physical symptoms ranging from mild gastrointestinal discomfort to life-threatening anaphylaxis. Curiously, there is growing evidence that some food-allergic individuals experience changes in mood and behavior after consuming an offending food despite not experiencing severe physical symptoms. However, the mechanism(s) through which food allergy may affect the brain and behavior has yet to be elucidated. Previously, we found that inducing non-anaphylactic cow’s milk allergy (CMA) in mice resulted in abnormal behavior, neuroinflammation, and an increased the number of brain mast …

Theses and Dissertations
Lyme disease, caused by Borrelia burgdorferi, is currently the most prevalent vector borne disease in North America. With the CDC estimating almost 500,000 new cases every year, methods are needed to control the vector, the black legged tick (Ixodes scapularis). Like other tick-borne diseases, Lyme disease is zoonotic and involves tick parasitism on rodent reservoirs in the wild. The main reservoir host of Lyme disease is the white-footed mouse (Peromyscus leucopus). This study aims to explore the effectiveness of a reservoir targeted control approach by the treatment of white-footed mice with oral isoxazoline class drugs. …
A Measure Predicting Treatment Outcome For Sexual Offenders, Kaitlin Alyssa Guston
A Measure Predicting Treatment Outcome For Sexual Offenders, Kaitlin Alyssa Guston
Theses and Dissertations
Researchers generally agree that treatment reduces the likelihood of sexual offender recidivism. However, studies show attrition rates of up to 85% in some treatment programs for sex offenders. Because many risk factors for recidivism and treatment attrition are the same, the present study used gold-standard risk assessments to predict which sex offenders would not complete a community treatment program. The Static-99r, Stable-2007, and URICA assessed static risk factors, dynamic needs, and responsivity to treatment for 289 sex offenders. Pre-treatment scores from the sex offenders in the sample indicated that these assessment instruments could predict treatment attrition for sex offenders in …

The Effects Of Covid-19 On School Attendance: Examining Explanations For Chronically Absent Students, Samantha Kaloustian
Theses and Dissertations
Kindergarten through 12th grade school administrators and educators are tasked with the challenge of ensuring every student is consistently attending school. Balfanz and Byrnes (2012) and Henderson et al. (2014) stated that either students cannot attend school because of multiple factors, students will not attend, or students do not attend because of a lack of value in education. Then, in 2020, the school attendance challenge was heightened with educating students during a worldwide pandemic. During this time, school environments varied from 100% virtual learning to hybrid learning—meaning they had both virtual and face-to-face instruction—to 100% face-to-face instruction. After knowing how …
