Spaceflight Safety Regulations: The Case For Implementing Safety Management Systems In The Developing U.S. Commercial Human Spaceflight Industry, Carly Davidson

Theses and Dissertations

Accidents have historically accompanied the development of new transportation systems, often due to technical failures; but human factors – such as organizational culture and management decisions – are increasingly recognized as significant contributors. A strong safety culture, prioritizing safety at all organizational levels, effective management procedures, and open reporting of violations, is believed to improve outcomes by proactively reducing risk in highly technical organizations. These elements form the basis of Safety Management Systems (SMS), which include safety policy, risk management, assurance, and promotion. As commercial spaceflight expands public access to space, US regulators must develop flexible safety regulations that protect …

Applicability Of Cementochronology To Estimate Season-Of-Death In Humans: Insights From Modern Documented Collections, Olga Ibarra-Sanchez

Theses and Dissertations

Dental cementum is characterized by lifelong deposition of alternating opaque annuli in fall/winter and translucent bands in spring/summer. This study aims to test the applicability of cementochronology to estimate season-of-death, by observing the properties of the last layer, with direct implications for forensic anthropology and bioarchaeology. The sample includes canine teeth from 146 adults (84 males, 62 females), age-at-death ranging from 20-97 years (mean=61.7 years, SD=18.6 years), from two contemporary skeletal collections. Of these individuals, 78 (53.4%) died in spring/summer and 68 (46.6%) died in fall/winter. Overall accuracy was low at 64.4% (94/146). Accuracy was higher for spring/summer deaths 100.0% …

Testing Microscopic Approaches For Cementochronology In The 21st Century Identified Skeletal Collection, Portugal, Amando Luis Montalvo Jr.

Theses and Dissertations

Age-at-death estimation is a key component to the creation of a biological profile in forensic anthropology. Acellular extrinsic fiber cementum annulations have been shown to correlate with chronological age. Cementochronology examines this correlation through the sum of the alternating translucent bands and opaque annuli, and the age of eruption of a tooth. While several microscopy techniques have been used, there is no consensus on the most optimal. This study will assess the reliability, precision and accuracy of three microscopy techniques: Brightfield (BF), Phase Contrast (PC) and Differential Interference Contrast (DIC). PC was the most reliable (rTEM= 10.4%), the most precise …

Punitiveness In The Modern Era: Gender Roles & Anti-Transgender Attitudes, Haley Brooke Trantham

Theses and Dissertations

Public opinion on punitiveness is an important topic of study because it can influence political elites’ decision making when developing legislation. This study focused on the role gender ideology and anti-transgender attitudes on punitiveness while controlling for religious and political conservatism. The 2020 American National Election Study (ANES) was used to examine the association between conservatism, traditional gender roles, and anti-transgender attitudes on their influence of punitiveness. Three ordinal logistic regressions were run for each type of punitiveness (i.e., death penalty support, crime spending, and felon disenfranchisement). Results indicated that religious conservatives had lesser odds for supporting the death penalty …

Confirmatory Factor Analysis Of The Psychopathic Personality Inventory-Revised: Short Form In College-Attending Emerging Adults, Lydia Stanhope

Theses and Dissertations

Psychopathy research stems from the work of Dr. Hervey Cleckley, whose research aided in providing the foundation for psychopathy assessments currently utilized in the field. Several researchers used Cleckley’s framework to further home in on characteristics that are central to psychopathy. Among the primary researchers who adapted the characteristics into their own measures are Robert Hare, Paul Frick, and Scott Lilienfeld; the work of these researchers is what helped lead to the creation of the Psychopathic Personality Inventory-Revised: Short Form (PPI-R: SF). The current study aimed to confirm the two-, three-, and eight-factor models from previous versions of the measure …

Barriers To Hispanic Post-Secondary Education In Science Fields, Luis Slayton

Theses and Dissertations

The study aimed to examine whether external barriers could be identified and are present throughout a Hispanic individual's educational life. The beliefs of the Hispanic community regarding education and the nature of acquiring an education could be relevant to the factors that impede the completion of high school. A survey approach was chosen as the methodology for the study due to the confidential nature of a questionnaire. Human nature tends to be more honest when not asked personal questions face-to-face. Additionally, there is potential to generalize attributes from a small sample to a larger population, allowing inferences about the identified …

Causal Neuro-Symbolic Artificial Intelligence: Synergy Between Neuro-Symbolic And Causal Artificial Intelligence, Utkarshani Jaimini

Theses and Dissertations

Understanding and reasoning about cause and effect is innate to human cognition. In everyday life, humans continuously engage in causal reasoning and hypothetical retrospection to make decisions, plan actions, and interpret events. This cognitive ability allows us to ask questions such as: “What caused this situation?”, “What will happen if I take this action?”, or “What would have happened had I chosen differently?” This intuitive capacity to form mental models of the world, infer causal relationships, and reason about alternative scenarios, particularly counterfactuals, is central to our intelligence and adaptability. In contrast, current machine learning (ML) and artificial intelligence (AI) …

Investigating The Ecology Of The Homeless Court: The Promise Of Quasi-Experimental And Statistical Learning Methods, Dylan Wong

Theses and Dissertations

Interactions with the legal system are a crucial factor in maintaining homelessness. Difficulties in addressing legal issues are barriers to accessing services and finding employment and housing. Across the United States, the homeless court is an emerging legal program that has been developed to break this cycle, but they appear to face numerous capacity and coordination problems. Few empirical and systematic investigations have been conducted on homeless court programs. Further, previous studies of homeless courts focus their process and outcome measures on the priorities of the legal system. An investigation into the ecology, or environmental context, of homeless persons would …

Unveiling Injustices In Theodore Dreiser's “An American Tragedy” And Susan Glaspell's “A Jury Of Her Peers”, Athena Maria Dotsikas

Theses and Dissertations

Crime and its representation in new age media is seeping into every avenue of discussion nowadays. The influence of crime is most notably evident in literature, where real cases inspired fictional novels and short stories that explore social issues and injustices. Since the 16th century, true crime has captivated human curiosity while also shedding light on the United States legal and justice system. Ultimately, true crime narratives provide a deeper understanding of human psychology and the reasons behind a number of gruesome and horrific incidents. This thesis investigates how Theodore Dreiser’s An American Tragedy and Susan Glaspell’s A Jury of …

The Instrumentalization Of The Unprivileged Combatants By Western Countries Aimed To Oppress National Liberation Wars, Fares Mahmoud Def-Allah Abdelhamid

Theses and Dissertations

The goal of International Humanitarian Law (IHL) is purported to be the humanization of wars. Nonetheless, the atrocities committed in wars and the war criminals’ impunity suggest the failure of IHL. Notwithstanding, some voices call for reforming and developing IHL. In contrast, this thesis argues that IHL should be rejected entirely since the distinction between privileged and unprivileged combatants indicates that IHL is biased against anti-colonizers. It is biased in three senses. Firstly, IHL, particularly the distinction between privileged and unprivileged combatants, is dominated by Western rationality, which can be noticed in the domination of the civilization concept with its …

Just Do Something: Framing A Movement To Fight Fascism, Heather-Ann Layth

Theses and Dissertations

This study seeks to better understand antifascist activism, in part to add sociological perspectives to the antifascist movement and better understand a group publicly maligned by negative portrayals by politicians and the media. This study is important because fascism is already doing real damage to marginalized Americans and represents a real threat of further identitarian and authoritarian oppression. Yet, the movement against growing fascism has been painted as a boogeyman in the public eye. Efforts to stop neo-Nazis and white supremacists from gathering are not discussed in terms of fighting fascism but rather in terms which criminalize and demonize antifascists. …

Identification Of Cadmium As A Structural And Functional Modulator Of Psd-95 Regulating Nmdars At Postsynaptic Membranes, Claudia Garza

Theses and Dissertations

Postsynaptic density-95 (PSD-95) is an essential scaffolding protein in excitatory neurons. PSD-95’s N-terminal palmitoylation region elicits synaptic plasticity by targeting, anchoring, and trafficking glutamate receptors, such as N-methyl-d-aspartate receptors (NMDAR), to the postsynaptic membrane. The molecular interactions of PSD-95 and its dysregulation in excitatory synapses are currently being explored as primary causes of neurodegenerative diseases and disorders, such as Alzheimer’s disease, Schizophrenia, and Parkinson’s disease. Recent studies demonstrate an overaccumulation of zinc at two cysteines (C3 and C5) and two histidines (H24 and H28) of PSD-95 blocks palmitoylation, causing a loss of NMDAR at the postsynaptic membrane. In addition, exposure …

The Effects Of Placing Students In Special Education In A Disciplinary Alternative Education Program, Daniel Garza
