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 …

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

Immersion is an important aspect of entertainment media because it both drives the use of media and heightens one’s experience with that media (Nilsson et al., 2016). There are three core aspects of immersion. These aspects are (1) narrative engagement, (2) flow, and (3) enjoyment. This study set out to determine whether these aspects are statistically distinct from one another when observed in video games. The result indicated that these aspects were distinct from one another when examined through a structural equation model. This indicates that creating an overarching immersion variable that combines the different aspects of immersion may not …

Countries As Laboratories: Reflections On Sierra Leone’S Amended Anti-Human Trafficking Law, Andrea L. Dennis

Scholarly Works

Sierra Leone’s improved anti-trafficking laws align with global norms, but enforcement remains weak due to socio-economic realities and Western deterrence mismatches, limiting effective prosecution despite recent legislative reforms.

The Hidden Cost Of Venture Capital, Emilie Aguirre

Faculty Scholarship

Founders, employees, consumers, and even funders increasingly expect businesses to pursue social goals alongside financial performance. Yet even the most committed firms have found it difficult to maintain social performance over time. Scholars in economics, management, and law have put forth several explanations for this “mission drift,” including inappropriate governance, poor management, lack of genuine commitment, and threat of takeovers. Puzzlingly, research to date primarily focuses on later-stage firms, even though the events and decisions that take place in a firm’s early stages can critically impact retention of its social performance.

Drawing from over five years of qualitative field research …

Technological Development Of In-Cell Nmr: Microfluidic, Metabolomic, And Fluxomic Approaches, Nicholas Sciolino

Electronic Theses & Dissertations (2024 - present)

In the fields of structural biology, metabolomics, and fluxomics, there is a driving, technique-based concern when it comes to high-resolution spectrometry and its marriage to biological and physiological relevance. Sample preparation often involves cellular perturbation, lysate separation schemes, combinations with non-biological reagents, and timeline slack. Conceptually, the farther we get from the cell, the greater the potential disparity between what exists in vivo and our in vitro manipulations. This is particularly true when seeking to collect data on transfected targets of interest, and on sensitive metabolic equilibria that occur on the order of minutes. The question remains: if we are …

The Purpose Of The Preliminary Injunction, Samuel Bray

Journal Articles

This Article explores a reshaping of the preliminary injunction that is occurring in the federal courts. A preliminary injunction is designed to be a "hold in place" order, blocking actions by the parties that would undermine the efficacy of the court's remedial options. But the preliminary injunction is becoming a device for accelerating the merits decision. Instead of a four-factor test for preliminary relief, increasingly there is one factor: the merits. This Article critiques this transformation, and it argues that the preliminary injunction should be recentered on the protection of the court's remedial options.
