The Effects of Implementing a Reward-Based Version of Ostrom's Eight Design Principles as an Intervention Package on Responses in a Common Pool Resource (CPR) Game (open access)

The Effects of Implementing a Reward-Based Version of Ostrom's Eight Design Principles as an Intervention Package on Responses in a Common Pool Resource (CPR) Game

The aim of behavior analysis has always been to apply technologies rooted in basic behavioral principles to problems of societal importance (e.g., Skinner, 1948; 1953; 1987). One such problem is the Tragedy of the Commons - a phenomenon arising from systemic failures among a community, leading to the total collapse of a critical resource (Hardin, 1968). Elinor Ostrom's Eight Design Principles were developed to provide a framework for the self-management of common pool resources (CPRs; Ostrom, 1990/2015). When applied as an independently manipulated variable, Ostrom's design principles have shown strong effects in the management of CPRs within the context of a tabletop board game Catan® (Smith & Becker, 2023). This preparation included both rewards (i.e., positive reinforcement) and sanctions (i.e., positive punishment) as a feature of the independent variable. However, it has been well documented that punishing and coercive contingencies can lead to problematic outcomes for individuals and societies (e.g., Sidman, 2001; Skinner, 1976). This study evaluated the effects of utilizing only rewarding consequences in lieu of sanctions in an effort to produce the previously observed control over self-management of a CPR, utilizing the previously adapted rules of the Catan® board game.

The Effect of Developmental Hypoxia on Cardiac Physiology in Three Species: Alligator mississippiensis, Chelydra serpentina, and Danio rerio

In this dissertation, I explored the effects of developmental hypoxia on heart contractility in three separate species of ectotherms: the common snapping turtle (Chelydra serpentina), the American alligator (Alligator mississippiensis), and the zebrafish (Danio rerio). I began with the common snapping turtle and tested whether the utilization of the sarcoplasmic reticulum was altered in response to developmental hypoxia. In the next two chapters, developmental hypoxia of the American alligator was explored studying how the cardiac tissue was affected, specifically in physiological stressors, sarcoplasmic reticulum utilization and sensitivity to pharmacological increases in contractility. The last chapter explored how zebrafish heart contractility was altered in response to chronic hypoxia from egg to adult. Findings from these chapters suggest that while developmental hypoxia did alter cardiac contractility, it did not alter the response of the heart to physiological stressors such as increased heart rate or under hypoxia. Overall, these findings contribute to increasing the current understanding of how developmental hypoxia alters the cardiovascular system but with an emphasis on the cardiac tissue level.

An Empirical Investigation of the Medical Supply Chain and Its Impact on Human Solid Organ Transplantation

The objective of this dissertation is to first identify if there are any academic research gaps in our understanding of the medical supply chain and secondly to understand the role and impact of logistics on the human organ transplant process. The first essay identifies the current status of medical supply chain literature and provides future direction for improving the medical supply chain. This was accomplished by preforming a systematic literature review and a bibliometric analysis from 2,160 publications was conducted. The second essay explores how logistical aspects impact transplant logistics performance and the quality of life for the transplant recipient. Survey data was collected from medical professionals and analyzed using structural equation modeling. The third essay identifies the factors are influencing the number of donor kidneys discarded each year. A retrospective analysis of all deceased donor kidneys procured in hospitals in UNOS region 4 (Texas and Oklahoma) from January 1, 2001, to June 28, 2021, was conducted. Data was analyzed using multinomial logit regression and panel data analysis. As a result, we identified several medical and logistics factors that have influenced the number of donor kidneys discarded in the United States.

An Analysis of Litigation against North Carolina Educators and School Districts under the North Carolina Tort Claims Act

This dissertation discussed the impact of the North Carolina Tort Claims Act and the history of governmental immunity that has protected school districts and school employees in North Carolina. The research question addressed was: how have North Carolina state courts interpreted the North Carolina Tort Claims Act in litigation against North Carolina school districts and their employees? The North Carolina Tort Claims Act provided citizens with a vehicle to sue local governmental agencies and their employees, such as school employees. The act also provided immunity for schools, especially for excessive damages in the case of negligence by an employee. The study examined how state courts have responded to different plaintiffs since the passage of the North Carolina Tort Claims Act in 1951. The decisions in the cases analyzed have been mostly favorable to schools, which has strengthened immunity for school employees. There were four legal aspects addressed by the courts after the passage of the North Carolina Tort Claims Act either most frequently or were unique to the case law of North Carolina. Those legal aspects were tests of school districts' governmental immunity; contributory negligence on the part of the plaintiff; the official capacity of school employees in lawsuits; and …

Acute and Sublethal Impacts of Crude Oil Photo-Induced Toxicity in an Early Life Stage Marine Fish (Sciaenops ocellatus) and Invertebrate (Americamysis bahia)

We investigated the modifying effects of ultraviolet (UV) light and chemical dispersant (Corexit 9500A) on crude oil toxicity in juvenile mysids (≤ 24 h) (Americamysis bahia) and larval red drum (24-72 hpf) (Sciaenops ocellatus). These results demonstrate that crude oil toxicity significantly increases with co-exposure to environmentally relevant UV levels in both species, indicating photo-induced toxicity. This toxicity was further exacerbated by the application of chemical dispersants which increased the dissolution and concentration of oil-derived polycyclic aromatic hydrocarbons (PAHs) in test solutions. To better understand the mechanisms and initiating events of this observed photo-induced toxicity, the incidence of apoptotic cell death and global transcriptomic changes were assessed in larval red drum (24-72 hpf) following co-exposure to crude oil and UV. These results showed that co-exposure to UV and low concentrations of crude oil (<1 µg/L ∑PAH50) induced apoptotic cell death in skin and eye tissue and altered transcriptomic pathways related to visual processing and dermatological disease. To link these cellular and molecular impacts of photo-induced toxicity to apical endpoints of ecological performance, sublethal impacts to growth, metabolic rate, and visually mediated behaviors were explored in larval red drum at 2 developmental stages. These results suggested that earlier life stages may …

Archive Activism: Memoir of a "Uniquely Nasty" Journey

Access: Use of this item is restricted to the UNT Community
Archive Activism is a memoir of activism rooted in a new way to converse with history—by rescuing it. Archive activists discover documents and other important materials often classified, “gone missing,” or sealed that somehow escaped the fireplace or shredder. It is an approach to LGBTQ advocacy and policy activism based on citizen archivery and original archival research to effect social change. Research=Activism is the formula growing out of Charles Francis’s personal story as a gay Texan born and raised during the 1950s and 1960s in Dallas. The rescues range in time and place from Francis’s first encounter with a raucous, near-violent religious demonstration in Fort Worth to attics loaded with forgotten historic treasures of LGBTQ pioneers. Archive Activism tells how Francis helped Governor George W. Bush achieve his dream of becoming president in 2000 by reaching out to gay and lesbian supporters, the first time a Republican candidate for president formally met with gay and lesbian Americans. This inspired Francis to engage with deleted LGBTQ history by forming a historical society with an edge, a new Mattachine Society of Washington, DC. For the first time, Archive Activism reveals how LGBTQ secrets were held for decades at the LBJ Presidential Library …
