Developing Concepts In Second Language (L2) Science From ‘Bits And Pieces’ Of Prior Knowledge: A Multiple Case Study Of Spanish-Speaking 4th And 5th Graders, María Isabel Martínez-Cuenca

Electronic Theses & Dissertations (2024 - present)

Earth science concepts sit at the intersection of the compounding difficulties English language learners’ (ELLs) face in content-integrated instruction. Emerging first language (L1) skills, emerging L2 language, and the difficulty of science terms interact with second language (L2) content learning. Moreover, L2 science concepts rarely develop incidentally through L2 socialization and instruction in the same naturalistic way as they do in the L1. Leveraging L1 resources may help ELLs in this process, yet there is a dearth of studies that consistently do so. This dissertation explores how, and the extent to which, leveraging ELLs’ pre-existing knowledge may support science and …

Development Of Dna Nanoswitches With Aptamer Based Detection For Thrombin, Camryn A. Beckles

Electronic Theses & Dissertations (2024 - present)

Bio-transducers are devices capable of converting the binding signals from molecular recognition events into readable signals for analytical detection. There is a need for modular bio-transducers that can specifically detect a wide range of analytes using a unified readout technique, as this approach could dramatically reduce costs of healthcare diagnostics and environmental monitoring.

To create such a modular transducer, the molecular recognition properties of aptamers will be used and integrated with the already established biosensing capabilities of DNA nanoswitches that reconfigure their shape in the presence of their target molecule. In this design, the detector strands of the nanoswitch will …

Misoscale Vortices In The Eyewall Boundary Layer Of A Tropical Cyclone In A Large Eddy Simulation, Emily A. Lucy

Electronic Theses & Dissertations (2024 - present)

Since the late 1980s, there have been numerous observations of extreme updrafts, gusts, and small-scale rotation in the eyewall of tropical cyclones (TCs). Research aircraft, dropsondes, and, more recently, mobile radars have collected these observations, most often from within the boundary layer. Previous studies have documented dropsondes associated with extreme gusts and updrafts, while others have discussed specific incidents of misoscale features in tropical cyclones. Several high-resolution numerical simulations of TCs have documented similar features. This study uses one such simulation from Worsnop et al. (2017). A small but intense tropical cyclone in a quiescent environment is simulated.

The Excessive Cost Of Health: An Analysis Of Pharmaceutical Accessibility Issues In The United States, Henry Woodman Curtis

Electronic Theses & Dissertations (2024 - present)

Compared to the rest of the world, the United States has one of the worst-performing health care systems. While this is influenced by our hospital systems and clinical care in certain contexts, one of the biggest culprits for our poor ratings is the cost and availability of prescription medications. We pay more than any comparable country for the exact same medications and have a harder time actually accessing them. In this dissertation, I aim to analyze how individuals, companies, and governmental agencies have responded to various instances of high-cost or low-availability prescription medications. To begin, I examine pharmaceutical patenting practices …

Association Of Non-Communicable Diseases With Severe Covid-19 Among People Living With And Without Diagnosed Hiv/Aids In New York State, Ravi Kumar Balu

Electronic Theses & Dissertations (2024 - present)

Background: People living with diagnosed HIV (PLWDH) have a higher chance of co-infections and co-morbidities than the general population. When SARS-CoV-2 was first reported in China in December 2019 and later declared a pandemic, it was speculated that PLWDH might be more prone to SARS-CoV-2 infection and severe disease outcomes given their increased vulnerability to other respiratory infections like influenza, pneumococcal pneumonia and tuberculosis. However, several facets of COVID-19 disease in PLWDH are incompletely understood, including whether non-communicable diseases (NCDs) are strong risk factors for severe disease outcomes and death as they are in the general population.

Methods: The data …

The Role Of The Nasal Migratory Mass In Olfactory Bulb Formation And Fertility, Charisse Martin

Electronic Theses & Dissertations (2024 - present)

The olfactory migratory mass plays an essential role in the development of the olfactory bulb by facilitating the migration of the gonadotropin-releasing hormone neurons from the olfactory placode to the pre-optic hypothalamic area in the brain. In mammals, the migration of GnRH neurons is critical for establishing the hypothalamic-pituitary-gonadal axis (HPG axis), which regulates reproductive function through the production and secretion of gonadotropins. Luteinizing hormone (LH) and Follicle-stimulating hormone (FSH) instruct the gonads to function appropriately, ensuring sexual maturation and fertility. Disruptions in this migratory pathway have been linked with Kallmann syndrome, a condition characterized by low levels of GnRH, …

Betti Numbers Of Generic Ideals, Jason R. Howell

Electronic Theses & Dissertations (2024 - present)

We present results related to Betti numbers of so called generic ideals over a polynomial ring $T = \Bbbk[x_1, \ldots, x_n]$. For each $m$ define $T(m) = T/(x_{m+1}, \ldots, x_n)$ and for a homogeneous ideal $J$ we use the notation $J(m) = JT(m)$. Also we set $Q(m) = T(m)/J(m)$, and $L(m) = ann_{Q(m)}(x_m)$. The first main result is Theorem \ref{Long Exact Sequence} where we produce the following long exact sequence \begin{align*} \cdots \rightarrow &Tor_{k+1,j}^{T(m-1)}(Q(m-1),\Bbbk) \rightarrow Tor_{k-1,j+1}^{T(m-1)}(L(m),\Bbbk)_{j-1} \rightarrow Tor_{k,j}^{T(m)}(Q(m),\Bbbk) \rightarrow \\ &Tor_{k,j}^{T(m-1)}(Q(m-1),\Bbbk) \rightarrow Tor_{k-2,j-1}^{T(m-1)}(L(m),\Bbbk) \rightarrow \cdots. \end{align*} The second main result is Theorem \ref{Theorem F(j,m) equiv k(j,m)} where we explicitly describe …

Street Outreach And Reentry: The Role Of Community Violence Intervention In The Reintegration Of Returning Citizens, Hilary Jackl

Electronic Theses & Dissertations (2024 - present)

Amidst ongoing efforts to reduce the nation’s prison population, as well as calls to defund the police and invest in civilianized public safety strategies following the murder of George Floyd, community-based violence intervention (CVI) strategies have been increasingly recognized as a critical means by which to ameliorate the United States’ enduring gun violence problem without exacerbating the harms of overpolicing and mass incarceration. However, most contemporary CVI research has assessed program impacts on neighborhood rates of gun violence and has produced conflicting findings, leading scholars to call for the need to examine a wider range of program-related functions and outcomes. …

Comparison Of Methane Emission Quantification Methods At Landfills In New York State, Alexandra M. Catena

Electronic Theses & Dissertations (2024 - present)

Greenhouse gas (GHG) emission increases are a consequence of global population rise and economic growth. It is well known that carbon dioxide is the dominant GHG by mass, but methane has received increasing attention recently due to its high warming potential and relatively short lifetime of about a decade. Methane has several different types of both natural and anthropogenic sources including wetlands, waste management, energy, agriculture and farming, and wildfires, which makes tracking and reducing methane emissions a complex problem. The emission rates of each of these sources are highly uncertain due to differing emission estimation methods, which can be …

Nat10 Stabilizes Immune Response Factors Aiding With Cellular Immune Response To Zika Virus Infection, Shawn Gianola

Electronic Theses & Dissertations (2024 - present)

Zika virus (ZIKV) remains a significant public health concern due to major gaps in our understanding of its infection mechanisms and immune evasion strategies. Despite its link to severe complications such as microcephaly and Guillain-Barré Syndrome (GBS), no vaccine or targeted antiviral therapies exist. Compounding this concern is the expanding habitat of ZIKV-carrying mosquito vectors, driven by climate change, which increases the risk of future outbreaks in previously unaffected regions.

One promising area of investigation involves post-transcriptional modifications (PTMs) chemical alterations to RNA that influence its stability, translation, and function. Although over 170 PTMs have been identified, their roles remain …

Does Type Of Metta Phrase Impact The Acceptability And Utility Of Loving-Kindness Interventions: An Experimental Evaluation, Shannon B. Underwood

Electronic Theses & Dissertations (2024 - present)

Loving-kindness (metta) meditation (LKM) is a widely utilized self-compassion intervention with numerous biopsychosocial benefits. Yet a smaller, emerging body of evidence suggests that LKM is difficult and various barriers impact its accessibility and effectiveness. Relational Frame Theory provides a behavioral and contextual perspective of language and cognition that may help clarify how LKM may yield receptivity or rejection of the practice itself. Prior research examining the role of language in LKM identified specific metta phrases more likely to evoke a coordinated (i.e., sameness/agreement) or oppositional (i.e., rejection/lacking) response, and found that indices of psychological suffering predicted oppositional responding (Underwood, 2023). …

Backgrounds And Efficiencies For Low-Energy Searches, And Improved Calibration Techniques In The Lux-Zeplin Dark Matter Experiment, Gregory M. Blockinger

Electronic Theses & Dissertations (2024 - present)

The full understanding of dark matter has eluded physicists for many years. While there is abundant astrophysical evidence across many scales, the exact nature of this matter, which comprises about 25% of the Universe’s energy density, remains unknown. Weakly Interacting Massive Particles (WIMPs) are one of the leading theoretical candidates, and numerous ex- periments have searched for their interactions. In recent decades, dual-phase Time Projection Chambers (TPCs) have become the leading technology in this search. The LUX-ZEPLIN (LZ) detector is one such xenon-based experiment, operating nearly a mile underground in the Black Hills of South Dakota at the Sanford Underground …

Boundary Conditions, Symmetries, And Bootstrap In 2d Conformal Field Theory, Yucong Cai

Electronic Theses & Dissertations (2024 - present)

This dissertation contains two parts of study on the Friedan states and on the conformal bootstrap with symmetries.

The Friedan states are potential physical boundary states of the free boson. However, they exhibited a continuous spectrum in the open string sector, in contrast to more standard examples. The explicit expressions for the density of states of the Friedan states is obtained. Some pathologies and possible contradictions of these states are explored. The $g$ functions of the Friedan states are shown to be infinite, suggesting an infinite number of degrees of freedom in the theory.

The modular conformal bootstrap using the …

Y’All Means All: Pro-Choice Abortion Activism In West Texas Post-Dobbs, Hannah S. Noblewolf

Electronic Theses & Dissertations (2024 - present)

In the spring of 2021, a six-week abortion ban passed by popular vote in the city of Westerburg, Texas. It had a civil enforcement mechanism, allowing someone to collect a reward of $2,000 if they successfully sued someone they reported for “aiding and abetting” abortion. The ban, called the Westerburg Sanctuary City ordinance, was referred to as “bounty hunting.” When the ban passed it became the template for the state-level Texas Heartbeat Act, which provides a greater financial reward for a successful civil suit, with a minimum of $10,000 plus legal fees. In the face of this ban, pro-choice activists …

Identification Of Fentanyl And Fentanyl Analogs Found In Human Urine Using Gas Chromatography-Mass Spectrometry, Adam M. Fisher

Electronic Theses & Dissertations (2024 - present)

Identification of fentanyl and its analogs in unknown samples is a frequent practice completed in forensic crime labs, as the fentanyl epidemic continues. With the continued increase in illicit drug use, crime labs are not able to keep up with the flooding of new fentanyl analogs being developed, resulting in new analogs slipping past the crime labs’ authority. This research is to start to develop a database of commonly found fentanyl analogs in New York State. Gas Chromatography-Mass Spectrometry (GC-MS) is a widely used method for the detection and identification of illicit drugs in forensic crime labs. A database that …

Improving Generalizability In Image Manipulation Detection, Zhenfei Zhang

Electronic Theses & Dissertations (2024 - present)

Image manipulation detection (IMD) aims to determine whether an image has been tampered with and to identify the manipulated regions. These capabilities have become increasingly important with the rapid advancement of media editing and generation technologies, such as Photoshop and generative AI methods, which underscore the need for robust tools for media authentication. Although current state-of-the-art (SoTA) methods achieve strong results on common manipulation types, such as splicing, copy-move, and removal, they often struggle to generalize to manipulation types not represented in the training data. Consequently, their real-world applicability remains limited, with performance degrading significantly in practical scenarios.

Pathways To Disclosure And Treatment Among Individuals With An Attraction To Minors, Theodore Jackson

Electronic Theses & Dissertations (2024 - present)

Child sexual abuse prevention is a significant social concern in the United States and internationally. While there have been some successful efforts to reduce recidivism risk among individuals who have committed sexual offenses, we fall short when preventing first time offenses. Therefore, looking at ways to provide treatment to those who are more at-risk for a first offense seems like a potential solution to this problem. One such relevant risk-factor is attraction to minors. This study is a qualitative examination using Interpretive Phenomenological Analysis of how people who are attracted to minors make the decision to disclose their attraction, seek …

A Social Exchange Perspective On Attentiveness As A Resource In Newcomer Relationship Development And Assimilation, Huy Q. Le

Electronic Theses & Dissertations (2024 - present)

My dissertation investigates the role of social relationships in newcomer socialization within organizations, emphasizing the importance of extra-role conversations in building affective trust and facilitating integration. I hypothesize that while attention to work-related tasks is crucial, engaging in extra-role conversations with supervisors and co-workers fosters affective trust, a key factor in socialization. I integrate social exchange theory, proposing that attention acts as a socioemotional resource exchanged in social interactions, leading to stronger affective trust and ultimately socialization outcomes. These informal interactions help newcomers adopt organizational values and integrate into social groups. I test my hypotheses using longitudinal archival data collected …
