Many of these proposals utilize machine learning methods to detect these malicious modifications with high accuracy and confidence. However, machine learning …

Transgender Students And The First Amendment, Dara Purvis

Faculty Scholarship

Suppose a transgender child experiences teasing and harassment from their classmates, whose hostile reactions interrupt the school day. School administrators tell the transgender child that, in order to allow educational activities to continue, they must dress in more gender-neutral clothing, ideally cionsistent with the sex they were assigned at birth. The student's parents protest, arguing that their child's clothing is speech that expresses their gender identity. The school points to Tinker v. Des Moines, allowing suppression of student speech where it creates a material disruption, as well as recent legislation characterizing discussion of gender identity as lewd and obscene. …

The Nebulous Binaries Of C.S. Lewis' Till We Have Faces, Amantia Menalla

Honors Undergraduate Theses

Much of C.S. Lewis’ novel Till We Have Faces can be examined through one of two binaries. The tension between rationality, or reason, and spirituality, or religion, is one of the core facets of both the text and its main character, Orual. Orual feels the pull of both ideas and thus spends most of the novel in a nebulous space between them. This tension is further complicated by the space between the feminine and the masculine which she also inhabits. By covering her face and body, Orual de-emphasizes her feminine identity and takes on a masculine role, dressing as a …

Bayesian Estimation Of Hierarchical Linear Models From Incomplete Data: Cluster-Level Non-Linear Effects And Small Sample Sizes, Dongho Shin

Theses and Dissertations

We consider Bayesian estimation of a hierarchical linear model (HLM) from small sample sizes. The continuous response Y and covariates C are partially observed and assumed missing at random. With C having linear effects, the HLM may be efficiently estimated by available methods. When C includes cluster-level covariates having interactive or other nonlinear effects given small sample sizes, however, maximum likelihood estimation is suboptimal, and existing Gibbs samplers are based on a Bayesian joint distribution compatible with the HLM, but impute missing values of C by a Metropolis algorithm via a proposal density having a constant variance while the target …

Development Of Novel Hydrogel Materials For Viscoelastically Accurate Brain Phantoms, Lila G. Schandler

Theses and Dissertations

Current methods such as concussion tests and Magnetic Resonance Imaging (MRI) scans only reveal structural damage post-injury. Creating an anatomically accurate model of the brain that mimics brain structure and viscoelastic properties will further allow medical professionals to analyze concussion events and create curated and personalized plans of recovery for a patient’s unique brain injury.

Values have been established for the necessary viscoelastic properties (time constants and elasticity) to mimic the native human brain tissue such as grey matter and white matter. The mechanical properties of the hydrogel are tunable by varying the concentration of Phytagel (PHY), a protein binding …

Restoration Is Repairing Relationships: Bridging Indigenous And Western Sciences To Assess The Socio-Ecological Restoration Of Wild Rice (Zizania Palustris) On Keweenaw Bay Indian Community Homelands, Cassandra M. Reed-Vandam

Dissertations, Master's Theses and Master's Reports

Manoomin (wild rice, Zizania palustris) is an ecologically and culturally significant plant relative for the Keweenaw Bay Indian Community (KBIC). Historically, manoomin was present across much of the Great Lakes, however, their presence has declined since the early 1900s and, by 1990, virtually disappeared within KBIC homelands. Employing ethnography, surveys, focus groups, and conversations with Ojibwa knowledge holders, this research defined successful manoomin restoration for KBIC and developed socio-ecological attributes and indicators to assess restoration presented in the Medicine Wheel Framework for Manoomin Restoration. Surface water, sediment, and pore water samples at six different manoomin sites were analyzed to …

New Method For Computing The Euclidean Condition Number With Rim-C, Cody Mccarthy

Dissertations, Master's Theses and Master's Reports

The condition number, being critical to solving linear systems, has many impor-
tant applications. Specifically for robust control analysis, the Euclidean norm has
widespread use over the 1-norm and ∞-norm such as determining a control system’s
stability to uncertainty [1]. Much work has been done with estimating the Euclidean
condition number, but current algorithms for computing said condition number, with
large matrices, tend to run slow as well as requiring a large amount of computa-
tional resources. This report seeks to provide a more time efficient algorithm that
utilizes MATLAB’s eigs, svds, and normest commands as well as the recently …

Colombia´S National Mountain Peatland Map: Peatland Distribution, Condition And Carbon Stocks, Patrick Nicolas Skillings-Neira

Dissertations, Master's Theses and Master's Reports

In this research, I explore the distribution, condition, and carbon stocks of peatlands in the Colombian Andes. High mountain peatlands in Colombia, usually found within the páramos, face significant ecological challenges. Although Law 1930 (2018) mandates sustainable páramo management, it does not prohibit peatland disturbance. Undisturbed peatlands act as long-term carbon sinks, but their degradation can convert them into greenhouse gas sources. The lack of comprehensive national peatland mapping hampers effective environmental management and policy formulation. I aim to create a national-scale peatland map, assess peatland distribution, quantify degraded pasture peatlands, and report preliminary soil carbon stocks. Additionally, I compared …

The Implications Of Artificial Intelligence In The Criminal Justice System, Natalie Garay

Honors Undergraduate Theses

This thesis focuses on artificial intelligence's recent implications on the criminal justice system regarding its admissibility as evidence in civil and criminal cases. One of the main concerns surrounding artificial intelligence is determining the validity of AI application; application refers to the accuracy "AI measures, classifies, or predicts what it is designed to" (Article: Artificial Intelligence as Evidence by Paul W. Grimm, Maura R. Grossman & Gordon V.Cormack.(https://scholarlycommons.law.northwestern.edu/cgi/viewcontent.cgi?article=1349&context=njtip). Privacy law will also be analyzed in this analysis. Is evidence recorded without the individual's consent or knowledge acceptable in determining an individual's guilt? This analysis will primarily focus on …

An Investigation Of Students' Modes Of Thinking Concerning Linearity In Linear Algebra, Noa Levy

Honors Undergraduate Theses

The intent of this thesis is to investigate student approaches to linearity within a linear algebra context, focusing on definitional, computational, and theoretical skills. Linear algebra’s abstract nature constitutes a major challenge for a significant sector of STEM students, with the course often serving as undergraduates’ first encounter with mathematical proofs and extrapolations. The current student struggle is reflected through the prominent gap in knowledge derived from a lack of a concrete understanding of rudimentary concepts (like linearity), pivotal to student success. As such, this investigation aimed to bridge this gap by considering students’ modes of thinking regarding the elementary …

Healthcare Disparities Among Hypermobile Spectrum Disorder And Hypermobile Ehlers-Danlos Syndrome Patients, Brooke A. Martinez

Honors Undergraduate Theses

Hypermobile Ehlers-Danlos Syndrome (hEDS) is the most common subtype of rare connective tissue disorder called Ehlers-Danlos Syndrome (EDS). Hypermobile Spectrum Disorder (HSD) is a connective tissue disorder that presents itself similarly to hEDS. Both disorders primarily affect individuals assigned to females at birth (AFAB), and symptoms range from joint instability, musculoskeletal pain, dizziness, fatigue, depression, and anxiety. Due to many factors like lack of education or attitudes among medical professionals (MPs), receiving a diagnosis of either of these conditions can be a challenging and grueling journey for patients. An online survey was conducted and distributed over social media platforms to …

Reliable Detection Of Wnt7a Protein In Transfected Human Embryonic Kidney 293 Cells, Henry Okonkwo

Honors Undergraduate Theses

Fetal Alcohol Spectrum Disorders (FASDs) refer to a set of development abnormalities affecting a fetus that can result from prenatal alcohol exposure (PAE). Studies performed by the National Institute of Health estimate that the pervasiveness of FASDs may number as high as 1 to 5 per 100 school children. Congenital heart defects (CHDs) are a subset of these abnormalities and have been observed to occur in 38% of children with FASDs. While there is an association between PAE and CHDs, the exact molecular mechanism as to how it occurs remains unclear. A 2022 RNA sequencing study points to the Wnt7a …

As online scams have become more common, it is critical to understand factors that can influence appraisal of potentially untrustworthy sources. The present study focused on language, in the form of self-reported bilingualism, and its relation to scam susceptibility. Language is a factor that contributes to alterations in brain structure, cognitive performance, and cognitive control systems. Bilinguals show advantages in the form of increased synaptic …

Deceptive Realities: Exploring The Nexus Of Fake News, Artificial Intelligence, And Public Perception, Victor E. Milanes

Honors Undergraduate Theses

Our research delves into two critical areas: fake news and artificial intelligence (AI). Historically, fake news predates the printing press, but its resurgence after the 2016 US Presidential Election garnered mass attention. Studies indicate its potency, with one fake article found to be as influential as a campaign ad (Allcott & Gentzkow, 2017). However, partisan media likely skews its impact on public perception.

Conversely, AI's integration has surged in recent years, sparking both excitement and concern among the public (Pew Research Center, 2022). Its ability to generate hyper-specific images, demonstrated by DALL·E 2 and Midjourney, poses challenges in distinguishing real …

Hybridization Kinetics Of Four-Way Junctions Localized On A Dna Scaffold, Katherine N. Taylor

Honors Undergraduate Theses

DNA computing is an ever-growing field with scientists trying to design structures that optimize logic gate communication to develop fast, biologically compatible, computational structures. We hypothesize that by using the principles of DNA computing, it is possible to design a DNA tile capable of studying localized DNA hybridization that can differentiate between oligonucleotides of different structural conformations. This includes synthetically manipulating DNA into a nanostructure that can perform Boolean logic functions to calculate the different rates of hybridization. To test our hypothesis, we designed a DNA Tile that incorporated a 4WJ using YES logic. Linear and hairpin single-stranded (ss) DNA …

A Tool To Automate Neuropathological Assessment In Huntington Disease Mouse Models, Samuel A. Moldenhauer

Honors Undergraduate Theses

As our life expectancy continues to rise, so does the prevalence of neurodegenerative diseases, such as Huntington disease (HD). Neurodegeneration leads to progressive regional brain atrophy, typically initiating prior to symptom onset. With the advancements of medical treatments designed to target neurodegeneration, researchers measure their impact on atrophy in animal models to assess their effectiveness. This is important because treatments designed to combat neuropathology are more likely to modify the disease itself, per contra to treatments designed to mask or treat symptoms. One method of brain region size quantification is magnetic resonance imaging (MRI), which while accurate, is prohibitively expensive. …

The Impact Of Prenatal Paternal Cigarette Smoke On Male Urogenital Disorders: A Systematic Review, Raphaelia V. Mcdonald

Honors Undergraduate Theses

Urogenital disorders, including cryptorchidism, hypospadias, and reduced semen quality, represent significant congenital and developmental challenges in male reproductive health. While maternal smoking during pregnancy is a well-established risk factor, emerging evidence indicates that paternal smoking may also have adverse effects on male offspring’s reproductive development. This systematic review assessed the impact of paternal cigarette smoke exposure before and during pregnancy on the incidence of various urogenital disorders.

By synthesizing data from five critical studies, we found that paternal smoking was associated with a 3.8-fold increased risk of cryptorchidism and hypospadias, a 1.26-fold reduction in semen quality, and potential epigenetic changes …
