Towards Human Explainable Digital Forensics: Generating Human Interpretable Evidence For Semantic Understanding In Manipulated Images And Text, Yuwei Chen

Electronic Theses & Dissertations (2024 - present)

Detecting and characterizing manipulations in digital media continues to pose a significant challenge within the field of digital forensics. Despite notable advancements, the discipline often remains in a reactive stance against emerging threats. Current state-of-the-art methods, typically evaluated within academic settings, fails to mirror the complexities of real-world disinformation scenarios. These methods generally prioritize high performance based on quantitative metrics, yet they demonstrate a considerable dependency on training data and lack adaptability to new novel attack signatures. With the rapid evolution of attack methodologies, the dependency on highly accurate models that do not generalize or adapt well to unseen threats …

On The Application Of The Diaconis-Holmes-Neal Sampler To Unimodal Underlying Probabilities, Christopher J. Lange

Electronic Theses & Dissertations (2024 - present)

Upon the introduction of the Metropolis et. al (1953) [6] algorithm, the question of how many steps in the Markov chain were needed to achieve convergence to stationarity became apparent. Eventually it was found that the convergence was rather slow, i.e. for a process on n states the number of steps needed to achieve convergence to stationarity was found to be on the order of n². [8]

The obvious problem with Metropolis et. al (1953) is that the Markov chain is reversible. [6] In other words, for any state j we can move from j to j + …

The Response Of Tropopause Phenomena To Stratospheric Variability: Rossby Wave Breaking And Tropopause Polar Vortices, Cameron R. Paquette

Electronic Theses & Dissertations (2024 - present)

Variability in the high-latitude wintertime stratospheric flow, often referred to as the stratospheric polar vortex, can precede anomalous conditions in tropospheric flow on subseasonal-to-seasonal (S2S) timescales and impact surface weather. The range of stratospheric impacts on tropospheric conditions range from shifts in the North Atlantic storm tracks, formation of cold spells, and development of extreme precipitation. Impacts of stratospheric variability are known to persist for up to 60 days, providing ample windows of opportunity in forecasting on S2S timescales. This dissertation focuses on the stratospheric impacts on tropopause-level processes, such as Rossby wave breaking (RWB) events and tropopause polar vortices …

Intention-Setting Among Recreational Psychedelic Users: Associated Acute Effects And Changes In Well-Being, Zi Ling Fiona Low

Electronic Theses & Dissertations (2024 - present)

Psychedelic intentions play an important role in shaping acute psychedelic experiences and influencing long-term outcomes. Limited existing literature suggests that different types of intentions are linked to acute experiences and outcomes in varying ways. However, data on the types of intentions set by recreational users remain scarce, and their effects lack clarity. This study investigates intention-setting practices among recreational psychedelic users, aiming to establish a taxonomy of intentions in naturalistic use contexts and clarify user perspectives on the impact of intention-setting. We also examine how domain-specific intentions correlate with acute psychedelic effects and changes in well-being. Finally, we test a …

Assessing Antiretroviral Therapy Prescribing Practices In New York State For Pregnant People Living With Hiv, Beverly Amofah

Electronic Theses & Dissertations (2024 - present)

ABSTRACT

Objective: The Panel on Treatment of HIV During Pregnancy and Prevention of Perinatal Transmission advises patient counseling to facilitate informed decision-making when evaluating changes in antiretroviral therapy (ART) during pregnancy and for patients to stay on suppressive regimens regardless of drug class. The purpose of this study was to investigate racial and ethnic disparities in the prescription of ‘preferred’ HIV drug regimens for pregnant people living with diagnosed HIV in New York State (NYS). This research also assessed whether prescribing practices for pregnant people on ART were consistent with Department of Health and Human Services (DHHS) guidelines.

Relational Mechanisms In Residential Eating Disorder Treatment: A Moderated Mediation Analysis, Bethany Ah Crawford

Electronic Theses & Dissertations (2024 - present)

Background. Eating Disorders (ED), previously described as a “disease of disconnection,” appear to have differing trajectories of treatment and behavior change based, in part, on feelings of connectedness to others during and outside of treatment. Patient experience of Relational Connectedness is not well-explored in ED treatment compared to other diagnoses but may be a valuable mechanism of change. Interpersonal problems are also known to impact outcome trajectories. Patients high in interpersonal and relational difficulties exhibit negative compensatory behaviors such as avoidance and hostility, which can deleteriously affect building a trusting relationship. Individual difference variables likely play a role in relationship-outcome …

Families’ Experiences Participating In A Collaborative, Multimodal Writing Workshop: Agency, Home Literacies, And Home/School Connections, Erin M. Faeth

Electronic Theses & Dissertations (2024 - present)

Students benefit academically and socially from strong home and school partnerships (Padak & Rasinski, 2010; Patrikakou et al., 2003; Risko & Walker-Dalhouse, 2009), yet there is often a gap between these contexts (Nelson, 2019; Padak & Rasinski, 2010; Risko & Walker-Dalhouse, 2009). To bridge the divide between these spaces, I drew on a sociocultural view of writing, the paradigm of family literacy, and third spaces of literacy to investigate four families’ experiences participating in a collaborative, multimodal writing workshop. Through practitioner research and case study methods, I explored the following research questions: (1) How do families talk about writing while …

Concurrent Parasympathetic Synchrony In Romantic Couples Exposed To Childhood Maltreatment Subtypes, Kate L. Senich

Electronic Theses & Dissertations (2024 - present)

Early responsive caregiving hones children’s physiological systems and subsequently supports social interactions (Feldman, 2007; Porges 2001; Steelman et al, 2002). Conversely, mis-attuned interactions with caregivers, such as exposure to maltreatment subtypes, might hinder social engagement capacities at both behavioral and biological levels (Kim & Cicchetti, 2004; Sheridan & McLaughlin et al., 2014). These early adverse influences endure across development and can affect behavioral and physiological interactions with romantic partners (Mayo et al., 2021; River et al., 2020; Zamir, 2022). Specifically, temporally coordinated patterns of physiological responses between partners (i.e., synchrony) are linked with important relationship behaviors, including conflict behaviors …

Divided By Fear: The Influence Of Political Beliefs On The Perception Of Extremist Groups, Hannah A. Scott

Electronic Theses & Dissertations (2024 - present)

Acts of violent extremism and support for political violence have increased in the United States over the past decade. Previous studies have primarily focused on the differences in risk perception between White Supremacists and Islamic Extremists/Jihadists, neglecting other ideological movements. This study utilizes data from the fifth wave of the Chapman Survey of American Fears and employs ordinal logistic regression to compare the fear of seven different extremist groups and movements: Islamic Extremists/Jihadists, the Militia/Patriot Movement, White Supremacists, Extreme Environmentalists, Extreme Animal Rightists, Anti-Immigration Groups, and ANTIFA. The findings reveal notable differences across political parties (Democrats, Republicans, and Independents) and …

From A Child's Perspective: A Qualitative Study Of Elementary School Student Engagement, Deanna J. Springstead-Gonzalez

Electronic Theses & Dissertations (2024 - present)

Abstract

Background and Purpose. This study sought to investigate child engagement from the children's perspective, aiming to understand better what they perceive as factors that facilitate or constrain their academic engagement in classrooms. By centering children's voices, this research challenges traditional views of students as passive recipients of education, instead recognizing them as active participants with valuable insights into their learning experiences. This work builds on the frameworks proposed by Shirley and Hargreaves (2021) and Lawson and Lawson (2013) that utilize socio-ecological theory to better understand those factors impacting children’s learning experiences.

Method. The study was conducted at an elementary …

Worldbuilding A Queer Before: D&D As A Neomedievalism For A Modern Age, Brianna M. Thompson

Electronic Theses & Dissertations (2024 - present)

Dungeons & Dragons (D&D) has had countless participants and audience members in the course of its over fifty-year existence. It has also been the subject of several studies that attempt to capture its unique form of performative play. Yet, there has been a scarcity of scholarship on how D&D acts as a neomedievalism and how that can offer a queer kind of opportunity to its players, allowing them to find a place in a past that is historically inaccessible and yet endlessly in the process of being (re)imagined. Using an interweaving of archival theory with queer and performance studies, particularly …

Perception As Creation In Swann's Way, Ethan D. Snowball

Electronic Theses & Dissertations (2024 - present)

Marcel Proust’s Swann’s Way is written with such detail that it overwhelms both the reader’s and the character’s sensory experience. Despite all the details, each character takes their senses of the world and strings them together as coherent images and stories. Proust shows that perceptions and memories are malleable, as individuals perceive objects in a way that brings entire stories or images to their conscious experience. The way that Proust’s characters take sensory objects and create images shows that each character can consciously interpret the world around them. Social images find themselves competing with the personally constructed images of an …

Postcolonial Notions Of Criminality In Jane Eyre And Wide Sargasso Sea, Hannah M. Karim

Electronic Theses & Dissertations (2024 - present)

This thesis will use Charlotte Brontë's Jane Eyre and Jean Rhys’s Wide Sargasso Sea to gain a greater understanding of the postcolonial notions of criminality that are sustained and reproduced through racialized purity rhetoric and hierarchy. I argue that the restriction of the definition of the human, within scientific, religious, and legal realms, functioned towards the colonial end of sustaining racial hierarchy. In terms of its means of functioning, I argue that its need to function discretely is a direct response to the abolishment of slavery and with it, the shifting social demand for an appearance of reason, moral righteousness, …

Elucidating The Effects Of Environmental And Physiological Conditions On Stem Cell Regulation In Vivo, Nimmy John

Electronic Theses & Dissertations (2024 - present)

The Notch signaling pathway is a highly conserved intercellular signaling pathway that any dysregulation can lead to a variety of human diseases. These diseases are further exacerbated by various environmental, pathological and genetic conditions. Previous studies have shown that these conditions have been known to affect the Notch transcriptional response. However, the molecular mechanisms by which such conditions influence Notch signaling remained largely unknown. Moreover, most Notch studies have relied on in vitro systems and indirect reporters, which can miss the dynamic and contextual nature of Notch signaling. Here, we systematically analyzed the effects of these conditions with single molecule …

The second chapter investigates the relationship between digital repression and the nature of conflicts using a …

"Can We See How It Works?" The Interactions Among Teacher, Student, And Content At A Living History Museum, Stacy E. Ward

Electronic Theses & Dissertations (2024 - present)

Today’s students need to be critical consumers of information. To that end, a thoughtful social studies curriculum provides students an opportunity to gain content knowledge and to practice thinking skills. However, elementary teachers, especially primary grade (K-2) teachers, often do not possess the skills and content knowledge to teach rich historical content and thinking skills. Teachers can partner with museum professionals and access museum content in this endeavor. Living history museums, immersive museums that interpret multiple buildings, trades, and heritage breed animals, hold the potential to be a strong partner for primary grade students, who are only 5-, 6- and, …

Heterogeneous Being: The Inhumanities And The Creative-Scientific Aesthetic, Steven L. Ogden

Electronic Theses & Dissertations (2024 - present)

Heterogeneous Being attempts to set the often-disunited aspects of the sciences and humanities in congruence and to extol and advance a hybrid creative-scientific aesthetic that moves beyond any restricted dimensions of its previously segregated fields of study. It likewise expresses the need to perpetuate that hybrid form of inquiry and representation to successfully address or convey the precarious realities of Earth’s ecological and environmental conditions. Heterogeneous Being asks readers to observe the inexhaustible proofs of our pluralized configurations with the nonhuman world, to recognize the agentic potentialities nonhuman subjects may hold both in and outside of those inhuman enmeshments, and …

Conserved A-Rich Regions In The 3’ Utr Of Zika Virus Differentially Affect Viral Gene Expression, Kristen Kaytes

Electronic Theses & Dissertations (2024 - present)

Following its discovery in 1947, Zika virus garnered little attention in the global stage until a rapidly spreading epidemic brough the virus to the global stage in 2015. Continuous advances in research have begun to further the understanding of the molecular biology of Zika virus, however much is still unknown. Much of our understanding of the virus comes from cross reference to other viruses within the same family, such as Dengue virus and West Nile virus. A commonality of these viruses is that they resemble cellular mRNAs and have a single-stranded positive-sense RNA genome that contains a 5’-cap but lacks …

Demonstration And Assessment Of Dark Field And Phase X-Ray Computed Tomography, Wadiah Hamed Allahyani

Electronic Theses & Dissertations (2024 - present)

Conventional computed tomography produces a 2D slice or 3D image from multiple conventional images to avoid overlapping structures and increase visualization of the internal features of the object. A set up, macro controls and processing for computed tomography was created for the Center for X-ray Optics for the first time, and demonstrated in this work. Adding differential phase contrast to conventional x-ray images highlights edges. Two more channels of information, dark field and integrated phase, improve the contrast and increase the signal-to-noise ratios of the image. Combining these channels with computed tomography is an important development. This work is the …

The Job Satisfaction Of New York State’S Public School Business And Marketing Education Teachers, Michael Lamastra

Electronic Theses & Dissertations (2024 - present)

The Strengthening Career and Technical Education for the 21st Century (Perkins) Act defines career and technical education as organized educational activities in which students learn applied academics, professional skills, and career training in a specific technical field. Many United States students, and ,specifically, New York State students, do not have access to CTE coursework. New York has seven CTE content areas: agriculture, business and marketing, computer science, family and consumer science, health sciences, technology, and trade/technical education.

One barrier to accessing this coursework is the availability of teaching staff. According to data collected by the New York State Education Department …

Testigos, Pero No Protagonistas: Bioficciones, Postmemoria Y Trauma Transgeneracional En Las Narrativas De Nona Fernández Y Rita Indiana, Fiordaliza Ippolito

Electronic Theses & Dissertations (2024 - present)

This dissertation examines how the concepts of biopolitics and postmemory are addressed in the narratives of Chilean author Nona Fernández (1971—) and Dominican author Rita Indiana (1977—) when portraying the dynamics of control and power in the totalitarian regimes of Augusto Pinochet’s dictatorship (1973-1990) and Joaquín Balaguer Twelve Years (1966-1978). Methodologically, the study explores biopolitics, which regulates the lives and bodies of citizens, and necropolitics, which dictates who can live and who must die, to understand state repression in both narrative contexts. Through the concept of postmemory, the research observes how the trauma of dictatorships is transmitted generationally and manifests …

Differences In Mental Health Outcomes In Immigrant Vs. U.S.-Born Populations In Urban Vs. Rural Areas In The United States, Zoë Gentles

Electronic Theses & Dissertations (2024 - present)

Background

The immigration process to the United States creates distinct mental stressors. These stressors are influenced by socioeconomic factors including income, education level and insurance status. In rural America, these factors are intensified due to a poor healthcare infrastructure that is limited. This study examines the relationship between urban-rural residence and mental health outcomes among immigrants vs. native-born residents in the United States.

Methods

Data from the National Health Interview Survey (NHIS) from 2019 and 2022 were used to examine the relationship. The exposure of interest was place of birth, and the outcome of interest was the presence of clinically …

Tapping A Hidden Resource In Classrooms: Peer Interactions And Their Role In Language, Literacy, And Disciplinary Literacy Practices Among Adolescent English And Non-English Learners, Jina Byeon

Electronic Theses & Dissertations (2024 - present)

This qualitative case study examines how peer interactions among six seventh-grade English Learners (ELs) and non-ELs serve as both a context for and a method of developing adolescents' literacy and disciplinary literacy practices. Data sources include two semi-structured interviews with each student and their four classroom teachers, student and teacher ethnographic interviews, 300 hours of classroom observations (in English Language Arts, Social Studies, Math and Science, English as a New Language Tutorial), and student-generated artifacts (e.g., worksheets).

Through the application of iterative and thematic data analysis, three key themes were identified: 1) adolescents' interactions with their peers fostered a supportive …

Investigation Of Electromigration Stresses Of Advanced Node Conductors Through Pulsed Power Behavior, Mohd Mueen Ul Islam Mattoo

Electronic Theses & Dissertations (2024 - present)

The microelectronics industry continues to put a heavy focus on preventing electromigration (EM) failures at advanced node conductors. The continuous scaling coupled with higher operating current densities further accentuate the problem. Most of the electromigration testing in the industry is performed with DC currents to evaluate the electromigration reliability of metal interconnects. However, most of the real-world applications operate using a pulsed current rather than a constant direct current. EM testing with pulsed direct current (PDC) show interesting results with how the current induced stress gradient evolves in absence of the electromigration driving force. It is generally assumed that the …

Personalizing Heat Information For Adults Over 65, Bruce C. Pollock Jr

Electronic Theses & Dissertations (2024 - present)

In the lead-up to extreme heat events, federal agencies, such as the National Weather Service (NWS), issue products and messages that advise people as to expected impacts, duration, and protective actions of the hazard. Within social media graphics, words such as “elderly” are used but are not defined by age. This can complicate personalization of risk to a hazard, such as extreme heat. I conducted focus groups across the United States and found that the term "elderly” was not understood among the general population. Additionally, I found that definitions of aging were tied to concepts such as mobility, resource access, …

The Developmental Impact Of Childhood Abuse: Heart Rate Variability, Adult Psychopathology, And The Protective Role Of Social Engagement, Rachel R. Mitchell

Electronic Theses & Dissertations (2024 - present)

Childhood abuse is a prevalent experience that can have a profound impact on health and well-being. Extensive literature has linked childhood abuse to an elevated risk of psychopathology, including suicidality and substance use. Recent neuroimaging and psychophysiological research suggest that childhood abuse may influence the development of the body’s stress response systems. Exposure to chronic and uncontrollable stress, such as childhood abuse, has been implicated in the dysregulation of neural circuits that govern autonomic control and emotion regulation. This study examined resting high-frequency heart rate variability (HF-HRV) as an index of physiological regulation and its associations with adult mental health …

Self-Preservation: Autobiography As A Form Of Archivization As Seen Through The Life And Poetic Works Of John Clare, Meghan J. Slaff

Electronic Theses & Dissertations (2024 - present)

This paper will look at how the processing efforts of an archivist mirror that of an autobiographer through the shared motivation of adding to the cultural memory or textual canon of a society. For archival purposes, the typical steps of ingesting, preparing, and presenting a collection are creation, capture, arrangement/description, and pluralization. To create an autobiography, writers take the memories that have been created and experienced due to events in their lives and capture those memories via recording in the literary form known as autobiography. These autobiographers then arrange and describe their memories in a way that shows vast similarities …

Further Results On Learning Quantum Measurement Classes: Quantum Pac Model For Povm Hypothesis Classes, Arka Prabha Das

Electronic Theses & Dissertations (2024 - present)

This thesis investigates the problem of learning from quantum systems, where each example consists of a quantum state paired with a classical outcome. The task centers on choosing an effective measurement rule from a fixed set to enable accurate prediction of the classical outcome from the quantum state. A central focus lies in understanding whether joint measurement strategies that cannot be separated into local operations offer a real benefit in terms of the number of examples needed for successful learning. We examine conditions under which a non-separable measurement within a given hypothesis class achieves strictly better sample complexity bounds compared …

Studies On Convexity Of Dnf Formulae, Josue A. Ruiz

Electronic Theses & Dissertations (2024 - present)

In this dissertation, we investigate the problem of determining whether a Boolean formula given in disjunctive normal form (DNF) is convex. Although Boolean formulas have various applications, our research focuses on the practical application for rule-based access control policies, where policies are often expressed as a set of Boolean rules. Understanding the structural properties of such formulas is crucial for determining whether a policy can be efficiently represented within a specific access control model.

The main contribution of this research is the conception and analysis of convexity derived from the “gap problem.” In this context, convexity is characterized by the …
