Between Physicalism And The New Dualism: The Moral Relevance Of The Human Body For Catholic Ethics, David J. Demboski

Electronic Theses and Dissertations

One could argue the remarkable changes to the landscape of Catholic moral theology over the course of the twentieth century were unparalleled in the history of the Church. Animated by anthropological and pastoral concerns, competing schools of Catholic ethicists introduced novel interpretations of natural law that sought to do greater justice to the entirety of the human person, not merely the physical dimension that tended to be emphasized throughout the manualist era. These unique and competing perspectives that emerged in the middle of the 1900s, found in the revisionist school and the New Natural Law Theory school, shaped the topography …

The Development And Optimization Of A Two-Dimensional Lc-Qqq-Ms-Method For The Combined Analysis Of Synthetic Cannabinoids And Designer Cathinones In Urine, Holly Penefsky

Electronic Theses and Dissertations

The compounds and chemical compositions of synthetic cannabinoids and designer cathinones are designed to mimic the intoxicating effects of D⁹-tetrahydrocannabinol and amphetamines, respectively. In order to skirt existing drug laws, non-controlled ingredients are used, and the original chemical structures of current drugs are being modified using analogs or derivatives. These continually changing chemical compositions pose a problem for policymakers, and forensic and analytical scientists, as users are able to attain a “legal high” and avoid detection in standard drug screens. Commonly, toxicology laboratories utilize a screening method, such as immunoassay, for the presumptive identification of designer drugs. When …

Trauma Informed Care In Alternative Education Settings, Cydney V. Quinn

Electronic Theses and Dissertations

Schools are considered to be the primary location for providing children with prevention and treatment for mental health symptoms, however, it is well documented that children’s mental health needs remain underserved. Especially at risk are children who have experienced trauma and other adverse childhood experiences (ACEs). Many children in this group are subject to disciplinary action, and are often removed from primary classrooms to alternative education placements (AEP) in an effort to manage behaviors. Therefore, it is important that alternative education teachers are trained in trauma-informed care (TIC). While it may be presumed that AEP staff would be well-versed in …

School Choice Considerations Of Black Parents Of Students With Dis/Abilities, Jaleah Robinson

Electronic Theses and Dissertations

Forty-four states and Washington, D.C. have passed legislation to expand school choice options for students and families (Cardine, 2019). In addition to a student’s assigned neighborhood school, one may enact choice by way of tax credits, charter schools, vouchers, relocation, and through other means, depending on where one lives. The act of choosing a school has been simplified by some to economic principles of competition and consumer satisfaction. What research has shown, however, is enacting school choice is much more complex and commonly intertwined with concepts of race, class, and ability (Ellison & Aloe, 2019). Academic quality (Mavrogordato & Stein, …

Identification Of Fluoxetine-Sert Interactions And Apo-Sert Studies Via Crosslinking Mass Spectrometry, Elizabeth Castellano

Electronic Theses and Dissertations

The serotonin transporter (SERT) is a member of the neurotransmitter sodium symporter family of transporters. SERT controls the magnitude and duration of serotonergic neurotransmission by facilitating the reuptake of serotonin back into the pre-synaptic neuron and is thus a target for antidepressants. Selective serotonin re-uptake inhibitors (SSRIs) such as fluoxetine, are commonly prescribed to treat depression. SSRIs act by blocking reuptake and prolonging serotonin signaling. However, significant problems regarding selectivity and mechanisms of action of these drugs remain unresolved. The structures of SERT and related transporters have been determined and serve as useful structural models. However, they are typically mutated …

Excremental Ecofeminism: Unearthing Waste’S Feminine And Narrative Agency In Early Modern Literature, Courtney Druzak

Electronic Theses and Dissertations

This project seeks to understand the role of forms of waste in early modern literary texts. It both offers up a theory—known as early modern excremental ecofeminism—for reading period specific texts in relation to waste and articulates how we may do so through close analysis of Edmund Spenser’s Faerie Queene, John Milton’s Paradise Lost, the elegies of Mary Sidney Herbert, the sonnet sequence Pamphilia to Amphilanthus by Mary Wroth, John Evelyn’s Fumifugium, and finally, William Shakespeare’s play Antony and Cleopatra. It chooses a variety of genres across texts from the 1580s to the 1660s both to interrogate …

Increasing Spiritual Leadership: An Analysis Of The “And Then Some” Components Of An Effective Mentoring Program For Lay Principals In The Altoona-Johnstown Diocese, Thomas Fleming, Jr.

Electronic Theses and Dissertations

Despite the opportunity for rowing to serve as an access point for innumerable young athletes to obtain financial and social support through a pathway to higher education, there remains …

Towards A "Universal Chemical Biology Toolbox" For Tackling Human Diseases, Christopher Swank

Electronic Theses and Dissertations

A lack of new drug targets and drug mechanisms, coupled with drug-pipeline attrition, represent significant problems in oncology drug discovery. Towards addressing this challenge, “fully-functionalized small-molecule probes” (FFSMPs) have been established, which are compounds that can be immediately used as “bait” to capture their protein targets under the same assay conditions used for oncology-based phenotypic screening. Specifically, each FFSMP library member contains one or more structural-diversity elements to promote interactions of the probe with different protein targets in living cells, an electrophile or photoreactive functional group for covalent attachment of the probe to interacting proteins via affinity or photoaffinity labeling, …
