Using A Dynamic Model To Assess Maintenance Of Deer Tick Virus Via Horizontal Transmission In Ixodes Scapularis Populations, Hannah Jane Sproch

Public Health Theses

IntroductionDeer Tick Virus—a lineage of Powassan Virus—is an emerging tick-borne flavivirus associated with high rates of morbidity and mortality. Although DTV infection is rare, there has been an observed increase in the number of human cases in recent decades, necessitating more public health attention. Ixodes scapularis ticks are known to be the primary vector of DTV. However, the enzootic cycle has yet to be fully characterized and there is evidence that horizontal transmission alone may be insufficient for DTV maintenance; it is hypothesized that vertical and co-feeding transmission are also necessary for sustained transmission.

MethodsA dynamic model was developed to …

Occupational And Socioeconomic Risk Factors Of Noise-Induced Hearing Loss, Rongcan Sun

Public Health Theses

Hazardous noise (>85 dBA) is among the most common occupational exposures and responsible for the majority of noise-induced hearing loss. Noise-induced hearing loss impacts many aspects of a person’s life, including workplace safety, daily routine, economic consequences, and quality of life. However, studies on the relationship between occupational noise exposure and hearing loss were usually done in specific industries rather than the general population. In addition, studies focused on associations between socioeconomic factors and hearing loss rarely take the type of occupation into consideration. In this study, we aim to evaluate both occupational noise exposure and socioeconomic status as …

Nutrition And Hookworm Infection: A Causal Analysis Of The Literature, Mengting Su

Public Health Theses

Hookworm infection is one of the neglected tropical diseases, particularly in low and middle-income countries, but we know relatively little about causal evidence related to malnutrition. This is mainly due to the relatively small research community compared to those investigating the impact of hookworm infection on host nutritional status and disease complications. Causal inference is critical in epidemiology and biomedical research because it can be a powerful tool in enlightening prevention efforts and developing etiology models. The application of causal criteria to address complex epidemiological research questions is indeed helpful in proposing more interventions to improve the health and well-being …

Operationalizing The Unesco Universal Declaration On Bioethics And Human Rights Through A Trans-Cultural Lens: A Qualitative Study With Students In South Korea And The United States, Francis Yang

Public Health Theses

The UNESCO Universal Declaration on Bioethics and Human Rights (UDBHR) was a well-intentioned but controversial document. Some scholars appreciated UNESCO’s attempts at providing an internationally recognized set of ethical guidelines. Other critics maintained the UDBHR, in particular Article 12, was yet another representation of Western ideological hegemony and an ill-informed attempt at embracing universality at the expense of diversity. This paper acknowledged this debate but approaches the UDBHR in trans-cultural manner, framing the UDBHR not as an imposing guideline, but as a seed around which dialogue can coalesce. Such dialogue might engage similarities, differences, and nuances between different ethical perspectives, …

Quantitative Real-Time Pcr Assays For The Detection Of Leptospira, Alice Zhao

Public Health Theses

Leptospirosis is an infectious zoonotic disease caused by bacteria of the genus Leptospira. The genus is comprised of 40 pathogenic species divided among P1 (19) and P2 (21). Leptospirosis incurs a disproportionately large burden of disease in urban slum regions of developing countries that lack adequate sewage disposal, water treatment, and sanitation infrastructure. While P1 species have been identified in cases of human infection, it is unclear if all Leptospira species are capable of infecting humans, especially P2 species. Among P1 species, L. interrogans has been described as the most frequent specie to cause disease in both animals and humans, …

The Cartulary Of Prémontré: People, Places, And Networks From Medieval To Digital, Yvonne Seale, Heather Wacha

History

The cartulary of the northern French abbey of Prémontré was produced in the mid-thirteenth century, and preserves acts dating mostly from the 1120s to 1230s, with some later additions. Although the abbey of Prémontré was the mother house of a prominent monastic order, and despite the relative abundance of its documentary record, that source base has been comparatively little studied. In this article, we discuss the process of undertaking the first full edition of this manuscript, some preliminary findings, and the scope that new digital technologies might afford in future prosopographical studies of the cartulary.

Residential And Race/Ethnicity Disparities In Heat Vulnerability In The United States, Mitchell Manware

Public Health Theses

Adverse health outcomes caused by extreme heat represent the most direct human health threat associated with the warming of the Earth’s climate. Socioeconomic, demographic, health, land cover, and temperature determinants contribute to heat vulnerability; however, nationwide patterns of residential and race/ethnicity disparities in heat vulnerability in the United States are poorly understood. This study aimed to develop a Heat Vulnerability Index (HVI) for the United States; to assess differences in heat vulnerability across geographies that have experienced historical and/or contemporary forms of marginalization; and to quantify HVI by race/ethnicity. Principal components analysis (PCA) was used to calculate census tract level …

Experiences During The Implementation Of Two Different Project-Based Learning Assignments In A Fluid Mechanics Course., Orlando Ayala, Kristie Gutierrez, Francisco Cima, Julia Noginova, Min Jung Lee, Stacie Ringleb, Pilar Pazos, Krishnanand Kaipa, Jennifer Kidd

Engineering Technology Faculty Publications

There is growing evidence of the effectiveness of project-based learning (PBL) in preparing students to solve complex problems. In PBL implementations in engineering, students are treated as professional engineers facing projects centered around real-world problems, including the complexity and uncertainty that influence such problems. Not only does this help students to analyze and solve an authentic real-world task, promoting critical thinking, but also students learn from each other, learning valuable communication and teamwork skills. Faculty play an important part by assuming non-conventional roles (e.g., client, senior professional engineer, consultant) to help students throughout this instructional and learning approach. Typically in …

Satirical Dissent: The Subversive Messaging Of Ad Reinhardt’S 1946 And 1961 Art Comics How To Look At Modern Art In America, Julie A. Schumacher

Dissertations and Theses

Through a close analysis of Ad Reinhard's 1946 and 1961 art comics "How to Look at Modern Art in America,” examined in the context of their times, this paper will argue that Reinhardt’s idealist view and involvement with abstraction, as he saw it in its “purest” form, was intrinsically formed and shaped by his Marxist anticapitalistic perspectives in response to his concurrent time. When these works are examined through the lens of Reinhard’s socialist politics, a parallel narrative surfaces where “pictures artists” also signifies capitalism and its capacity to harmonize and contaminate.

The Night Of The Long Knives: Reconsidered, Edward G. Gunning Jr.

Dissertations and Theses

The "Night of the Long Knives"—June 30, 1934, and the murderous days that followed is one of the more fascinating episodes in the history of the Third Reich. A year after taking power, multiple circles of influence challenged Nazi control. The National Socialists perceived enemies everywhere. At times the internal challenges were as significant as the external.

Much of the conflict centered on a myriad of perspectives on the nature and direction of the Nazi revolution. For Hitler, the revolution was complete, at least for now. His real revolution was a racial one, whose full dimensions only became manifest later. …

Self-Reclamation Through Death: Attaining Creoleness In Jamaica Kincaid’S The Autobiography Of My Mother And In Praise Of Creoleness By Jean Bernabé, Patrick Chamoiseau And Raphaël Confiant, Phillip J. Jordan

Dissertations and Theses

This thesis makes the claim that Xuela, the protagonist of the novel The Autobiography of My Mother mirrors the principles of the essay In Praise of Creoleness by Jean Bernabé, Patrick Chamoiseau, and Raphael Confiant. These works, published nearly a decade apart address a process of identity formation in which specifically Caribbean identity features blend together in a fluid and complex way, the process of creolization. The essay, In Praise of Creoleness, can be seen as the manifesto of creolization, while Kincaid’s Xuela in The Autobiography of My Mother is the manifestation. Kincaid’s work presents an account of an individual’s …

Cherokee Abstract Artist Leon Polk Smith: A Convergence Of Traditions, Danielle Montanino

Through examination contextualizing his work within the history and political events of the Cherokee, Chickasaw, and Choctaw Nations it is revealed how Polk Smith developed a formal language that could navigate both worlds and be viewed through a pure abstraction lens or a lens embodying his Indigenous traditions. In addition to his Indigenous philosophies, Mesoamerican Inca Nation’s cultural motifs further ground Polk Smith’s Indigenous aesthetic, and avant-garde …

Flawed Judgment: The Prolonged Failure Of Handschu V. Special Services Division, 1971-2022, Henry A. Burby

Dissertations and Theses

This thesis explores Handschu v. Special Services Division, an ongoing federal class-action suit brought by New York activists in 1971 to challenge the NYPD's right to use covert tactics to monitor them and undermine their political projects. The Handschu plaintiffs originally hoped that the court would find the NYPD's covert activities unconstitutional and would intervene on behalf of all New Yorkers thus targeted. After the conservative Burger Court challenged the pro-activist decisions of the previous Warren Court, the plaintiffs abandoned their ambitious goals and settled with the defendants. The Handschu defendants easily sidelined this settlement in the wake of the …
