Proposing A Measure Of Ethicality For Humans And Ai, Alejandro Jorge Napolitano Jawerbaum

Electronic Theses and Dissertations

Smarter people or intelligent machines are able to make more accurate inferences about their environment and other agents more efficiently than less intelligent agents. Formally: ‘Intelligence measures an agent’s ability to achieve goals in a wide range of environments.’ (Legg, 2008)

In this dissertation we extend this definition to include ethical behaviour and we will offer a mathematical formalism and a way to estimate how ethical an action is or will be, both for a human and for a computer, by calculating the expected values of random variables. Formally, we propose the following measure of ethicality, which is computable, or …

Examining School Nurses' Knowledge And Confidence Related To Their Intention To Screen For And Report Child Sexual Abuse: A Descriptive Cross-Sectional Study, Suzanne Ackers

Electronic Theses and Dissertations

Background: Child sexual abuse (CSA) in a preventable national public health problem that results in adverse health consequences. Research suggests many victims are currently attending school. Screening for early detection of health issues is integral to school nurse (SN) practice but there is little evidence that screening for CSA is occurring in schools despite recommendations that it should be. Lack of confidence and knowledge related to screening for suspected CSA contribute to a SN’s missed opportunity for early intervention.

Purpose: To describe SNs knowledge and self-efficacy associated with screening for and reporting CSA in school settings.

This study used an effective approach …

Glycerophosphocholine Is Used For Lipid And Phosphate Metabolism By Candida Albicans, Will King

Electronic Theses and Dissertations

The metabolism of phosphatidylcholine (PC), a major eukaryotic membrane lipid, has been shown to be an important aspect of pathogenesis in Candida albicans. Of note, PC turnover product, glycerophosphocholine (GPC), is abundant renal metabolite available within the host. GPC is readily imported by C. albicans, and deletion of the major GPC transporter, Git3, leads to decreased virulence in a bloodstream infection model. Here I have characterized two potential metabolic fates of internalized GPC. The first metabolic fate explored is internalized GPC can be hydrolyzed to release P_i. To determine if GPC import and subsequent metabolism impact phosphate …

Systematic Product And Process Design Of Versatile Perfluorocarbon Nanoemulsions For Elimination Of Hypoxia And Reactive Oxygen Species, Eric Lambert

Electronic Theses and Dissertations

According to a 2022 report, organs destined for transplantation are discarded 15% of the time for various reasons (Israni et al. 2022). This highlights a critical need in transplant practices. Transplant donor tissues are in need of essential nutrients, including molecular oxygen, to maintain integrity during preservation. A current trend in preservation is to perfuse the ex vivo tissue graft with nutrient-rich aqueous perfusate on a closed circuit. This practice, known as machine perfusion (MP) is limited by the absence of an oxygen-carrying component in the perfusate. Additionally, injuries to the recipient are sustained on reperfusion of the transplanted …

Assessment Of Facultative Sulfur Reducing Bacteria In Acidic And Circumneutral Passive Remediation Systems Using A Novel Culturing Technique, Natalie Lamagna

Electronic Theses and Dissertations

Pollution resulting from abandoned mine drainage (AMD) is widespread across the nation and impacts thousands of miles of watersheds in Pennsylvania alone. AMD contaminants pose hazards to ecosystems and to human health by lowering the pH and by suspending toxic heavy metals in water. Sulfur reducing bacteria (SRB) are known to remove metals and sulfur species from mine drainage through the formation of metal sulfide precipitates and have been documented to raise the alkalinity of water. Therefore, it is necessary to understand the environmental conditions in which these microorganisms survive. Environmental samples were collected from a circumneutral and an acidic …

Hoping As A Transformational Imperative In Puerto Rico: A Phenomenological And Grounded Theory Study Within Colonized Space, José Luiggi-Hernández

Electronic Theses and Dissertations

As the United States continues to restrict Puerto Rico’s self-determination and imposes oppressive institutions such as the Oversight Board, the people of the archipelago live in precarity and hopelessness. Limited psychological research on colonialism has focused on the detrimental impact of oppression and its influence on the development of fatalism and the inferiority complex. On the other hand, existing psychological theories of hope fail to describe how it is lived within the post-colonial context and to explain the ways in which this psychological phenomenon arises even in the face of systematic dehumanization. As Puerto Ricans show evident signs of hope …

Statistical Methods For Assessing Treatment Effects On Ordinal Outcomes And Selecting Optimal Treatment On Survival Outcomes Using Observational Data., Huirong Hu

Electronic Theses and Dissertations

This dissertation consists of two projects investigating statistical methods in causal inference and personalized medication using observational data. In the first project, we propose a parametric marginal structural ordinal logistic regression model (MS-OLRM) to assess treatment effects on ordinal outcomes. Average treatment effect (ATE) is used to measure the difference of the mean outcomes if all patients would have been treated compared with the outcomes if they would not have been treated. Many statistical methods have been developed to estimate ATE when the outcome is continuous or binary. The methodology on assessing treatment effect for an ordinal outcome is less …

The Relationships Between State-Level Economic Policies, Child Maltreatment, And Suicidal Behavior And Mortality., Yana B. Feygin

Electronic Theses and Dissertations

Suicide has proven to be difficult to predict and prevent at the individual level,1–3 so much so that a recent analysis of individual risk assessments found a maximal positive predictive value of 5.5% for suicide death,2 and suicide continues to be a leading cause of death among adolescents age 10-19 years.4 By targeting modifiable risk factors at the population level, policy has the potential to extend our reach to people and subgroups that are missed by individual level interventions. This ecological study of adolescent suicide rates, state policies, and child maltreatment in US states from 2005-2019 and Kentucky counties from …

It’S Not What You (Don’T) Eat, It’S What Eats You: Countering The U.S. Eating Disorder Master Narrative, Kelsea V. Schoenbauer

Electronic Theses and Dissertations

Eating disorders, including anorexia and bulimia nervosa, and binge-eating disorder, affect approximately 20 million women in the United States (National Eating Disorders Association, 2022d). The dominant approach to studying eating disorders is based on the master narrative of biomedicine. The present dissertation examines the existing master narrative by investigating the meaning that women themselves ascribe to their eating disorder experiences. Drawing upon notions of embodiment, the present dissertation proposes narrative theorizing as an appropriate lens through which to view women’s narrative sense-making processes and employs narrative research methods. Using a modified version of McAdams’ (2008b) life story interview protocol, I …

Novel Approach For Non-Invasive Prediction Of Body Shape And Habitus, Emma Young

Electronic Theses and Dissertations

While marker-based motion capture remains the gold standard in measuring human movement, accuracy is influenced by soft-tissue artifacts, particularly for subjects with high body mass index (BMI) where markers are not placed close to the underlying bone. Obesity influences joint loads and motion patterns, and BMI may not be sufficient to capture the distribution of a subject’s weight or to differentiate differences between subjects. Subjects in need of a joint replacement are more likely to have mobility issues or pain, which prevents exercise. Obesity also increases the likelihood of needing a total joint replacement. Accurate movement data for subjects with …

The Integration Of Catholic Mission And Ethics In Contributing To A Good Death, Noah Dimas

Electronic Theses and Dissertations

Catholic healthcare ethics exists within a morality that is under regular heavy scrutiny. This is furthered by the healthcare space itself becoming more secular as the greater society itself moves beyond the religious origins of healthcare. However, this does not have to be relegated to a negative. Rather, this can become a strong call to action for Catholic healthcare to rally together and advocate for itself in the wider healthcare space. This is especially true as these challenges to the Catholic moral-ethical framework begin to question the presence of both Catholic and religious healthcare as whole. These challenges, if left …

Soluble Epoxide Hydrolase Inhibition: A Novel Therapeutic Strategy For Alcohol-Associated Liver Disease., Jeffrey Warner

Electronic Theses and Dissertations

Introduction Alcohol-associated liver disease (ALD) is a common chronic liver disease and healthcare burden, and a spectrum of pathologies ranging from steatosis to steatohepatitis, fibrosis, and alcohol-associated hepatitis (AH). Despite its prevalence, there are limited effective therapeutic options for the treatment of ALD/AH. Previous evidence suggested that inhibition of soluble epoxide hydrolase (sEH), a lipid metabolism enzyme which degrades beneficial metabolites of dietary polyunsaturated fatty acids, may be a beneficial strategy. The central hypothesis of the current dissertation is that sEH inhibition will ameliorate alcohol-associated liver injury and inflammation in mouse models of ALD. Methods To determine the efficacy of …

Adverse Birth Outcomes: Investigating The Role Of Nativity And Perceived Racial Discrimination Among Black Mothers Enrolled In Des Moines, Iowa Healthy Start., Kendria Kelly-Taylor

Electronic Theses and Dissertations

Birth outcomes for Black women in the United States (US) are disproportionately worse in comparison to non-Black women, even when controlling for potential confounders. Existing studies suggest foreign-born (FB) Black women present better birth outcomes in comparison to US-born (USB) Black women. Also, the longer FB Black women live in the US, the more their perinatal health advantage diminishes. Racial discrimination has been hypothesized as a potential reason for this decline. This dissertation investigates the relationship between nativity and adverse birth outcomes while also exploring how the reporting of racial discrimination impacts birth outcomes among FB and USB Black mothers …
