Determining The Effects Of Imidacloprid On Non-Target Soil Organisms In Hemlock Stands, Braley Burke
Graduate Theses, Dissertations, and Problem Reports (ETD)
The hemlock woolly adelgid (HWA), Adelges tsugae Annand (Hemiptera: Adelgidae), is an invasive insect that is causing mortality of eastern hemlock trees, Tsuga canadensis, and Carolina hemlock trees, Tsuga caroliniana, across the eastern United States. To protect these ecologically important tree species, a neonicotinoid insecticide, imidacloprid, is commonly used. Imidacloprid is an effective treatment and can remain effective against HWA for four to six years but long-term (≥ one year after application) non-target effects of imidacloprid on forest ecosystems are not well-studied. This study examined terrestrial non-target effects of imidacloprid in hemlock stands with different treatment histories to …

Effects Of Acute And Chronic Nicotine Administration On Choice Of Probabilistic Outcomes, Katya A. Nolder
Graduate Theses, Dissertations, and Problem Reports (ETD)
Risky choice can be operationally defined as the choice for a larger, uncertain reinforcer over a smaller, certain reinforcer. Research suggests smokers engage in more risky or maladaptive decisions when compared to nonsmokers. The relation between nicotine and risky choice could benefit from further investigation, since nicotine is the active substance of tobacco products that maintains tobacco addiction. Acute nicotine administration has shown to alter risky choice; however, since the everyday smoker uses nicotine repeatedly, more research on chronic administration is warranted and would allow for assessment of tolerance or sensitization of these effects. The present study investigated effects of …

In Vitro And In Vivo Toxicological Evaluation Of Emissions From The Fused Filament Fabrication Three-Dimensional Printing, Mariana T. Farcas
Graduate Theses, Dissertations, and Problem Reports (ETD)
Fused filament fabrication (FFF), a three-dimensional (3-D) printing process, is an emerging technology that has recently gained wide popularity among both consumers and manufacturers. As filament is heated to above its glass transition temperature in a 3-D printer, a portion may undergo thermal decompostion, which releases ultrafine particles (UFP) and volatile organic compounds (VOCs) with potential adverse respiratory health effects are released into the air. This study's central hypotheses is that emissions generated during 3-D printing are toxic and exposure to these emissions induces pulmonary and systemic adverse health effects. Considering that currently, limited understanding is available on the health …

The knowledge of unsustainable human and Earth system interactions is widespread, especially in light of systemic environmental injustices. Systems science has enabled complex and rigorous understandings of human and Earth system dynamics, particularly relating to pollution of Earth’s land, water, air, and organisms. Given that many of these systems are not functioning sustainably or optimally, how might this field enable both rigorous understanding of the issues and experiments aimed at alternative outcomes? Here, we put forth a novel, multiscale systems science approach with three steps: (1) understanding the systemic issues at hand, (2) identifying systemic interventions, and (3) applying experiments …

Walden Dissertations and Doctoral Studies
Diabetes is one of America’s leading chronic diseases with comorbidities contributing to lower health statuses and increased health care costs. While it is known that lowering HbA1c reduces the deleterious effects of diabetes, the capability to identify people with diabetes at risk for uncontrolled HbA1c levels or developing comorbidities based on the compliance rates for different oral antihyperglycemic medication classes (OAMCs) and financial assistance programs does not yet exist. These quantitative longitudinal retrospective studies examined the association between medication compliance, using Proportion of Days Covered (PDC), by OAMC and Medicare financial aid programs, on predicting HbA1c levels and comorbidities in …

Millions of people die every year because of infectious diseases, and malaria is among the top five of the deadliest infectious disease. In 2018, malaria took more than four hundred thousand lives, and more than half of them are children under five years of age. Most malaria-affected parts of the world are also the home of the most underprivileged people. Seemingly, antimalarial drug discovery never achieved the attraction that it requires. Like malaria, another infectious disease that is not extensively explored by drug discovery campaigns is American trypanosomiasis or Chagas disease. More than a hundred years have passed since discovering …

Testing residential soil and paint for lead provides actionable information. By showing where and how much lead exists on the residence, it allows one to quantify risk and determine the best ways to reduce exposure along with the corresponding health and financial costs. For these reasons, several federal and state programs offer outreach to audiences on the benefits of testing residential soil and paint for lead. Not all individuals who know about lead’s adverse health effects, however, test their residence for lead, potentially limiting the actionable information that could have helped to reduce their exposure. Such individuals represent a challenge …

Legislators attempt to achieve intended goals by enacting laws that provide for regulatory enforcement. However, many times laws are unable to achieve their stated goals and in some ways may create new or exacerbate existing issues. Luckily, upon review, many of these issues can be fixed with quick modifications to either their implementation or enforcement mechanisms. In its current form, the Clean Air Act does not effectively account for differences in regional climate patterns, and, moreover, it perpetuates environmental injustice. If local governments were given more autonomy to enforce the Clean Air Act, they could shape its enforcement to more …
