A Multifactorial Approach To Improve Piglet Health And Survival, Aryeri Stephanie Bardales Castellanos

Electronic Theses and Dissertations

Pre-weaning mortality (PWM) remains a significant challenge in modern swine production systems, particularly in the context of hyper prolific sows. Although genetic selection has successfully increased litter sizes, these advancements have also intensified physiological stress on sows and increased the vulnerability of neonatal piglets. The majority of PWM occurs within the first 72 hours postpartum, with crushing by the sow as the leading cause of death. Additionally, iron deficiency anemia remains one of the most widespread nutritional disorders in piglets, further compromising survival, immune function, and growth. This thesis adopts a multifactorial approach to evaluate two management interventions aimed at …

Developing Proportional Hazards Mixture Cure Models And Predicting Risk For Persons With End-Stage Kidney Disease, Nathan Meyer

Electronic Theses and Dissertations

Traditional survival analysis techniques assume that all individuals will eventually experience the event of interest. This is as opposed to allowing for a subset of cured individuals. Hence, we consider a mixture cure model that can allow a subset of people to be cured of the disease and will never experience the event of interest. This gives a more accurate interpretation of survivability by analyzing both the shortand long-term effects of a set of variables on the individuals’ survival probabilities. However, the cure status is considered an unknown variable. Thus, the expectationmaximization algorithm is required to estimate this latent variable …

What Do We Get Out Of Our Entertainment? Empirically Determining The Differences Between Narrative Engagement And Flow Using Video Games, Lars Wagener

Electronic Theses and Dissertations
