Criminalization Of Homelessness: The Impact Of A Market-Oriented Approach, Gabriella M. Chioffi

Duke Journal of Comparative & International Law

Since the fourteenth century, countries have sought to criminalize unhoused individuals by labeling them as "vagrants." Currently, the United States and other countries continue to criminalize acts of sleeping rough, begging, loitering and other vagrancy-type activities that disproportionately target unhoused persons. Despite going through a period of decriminalization in the 1960s and 1970s, these punitive measures were largely reinstated by the 1990s. In the most extreme case, vagrancy criminalization was entrenched in a state's constitution. This Note contends that the reversion to punitive measures is triggered by a country's transition to a market-oriented approach that privatizes housing development and de-emphasizes …

The Spectral Response Of Time-Resolved Piv In A Turbulent Boundary Layer, Peter Manovski, Wagih Abu Rowin, Henry Ng, Paul Gulotta, Matteo Giacobello, Charitha De Silva, Nicholas Hutchins, Ivan Marusic

Student Publications

This study presents the application of time-resolved particle image velocimetry (TR-PIV) to measure the mean and fluctuating velocity components in a turbulent boundary layer (TBL) over an axisymmetric body of revolution. A narrow wall-normal strip of the flow was captured using a synchronised high-speed laser and camera at a recording frequency of up to 80 kHz. The resulting streamwise and wall-normal velocity TR-PIV data were validated against hot-wire anemometry measurements and direct numerical simulations (DNS) of a flat plate under matched flow conditions. The mean flow results showed good agreement between all methods, while the expected attenuation due to the …

Shrinkage Study In Photopolymerisable Hybrid Sol-Gel Through Holographic Patterning, Jamshed Aftab, Izabela Naydenova, Tatsiana Mikulchyk

Articles

Photopolymerisation induced shrinkage of holographic materials is one of the main factors which needs to be considered for designing holographic optical elements (HOEs) with high accuracy in light redirection with maximum efficiency. This work studies the shrinkage in photopolymerisable hybrid sol-gel (PHSG) by examining the properties of volume transmission gratings recorded in PHSG layers. It explores both the dependence of shrinkage on the holographic grating parameters (thickness, spatial frequency, slant angle) and the effect of material aging. By using the fringe-plane rotation model, shrinkage is found to have the maximum value of 1.37 % at 765 lines/mm (19.36° slant angle) …

Collaboration Across The Silos: Consultation As A Means For Integrating Services For Twice-Exceptional Learners, Kimberly Bowers Yoshino

Electronic Theses and Dissertations

Twice-exceptional (2e) learners are underserved in American schools. As students who demonstrate both giftedness and disabilities, 2e learners maintain profiles that warrant tailored educational services across special and gifted education programs. Yet, these programs are considered institutionally mutually exclusive as legal mandates create de facto isolation — the antithesis of what is recommended for the students’ optimal development. School psychologists have been identified as professionals critically positioned to support 2e learners because of their specialized skill set, namely in consultation. However, little is known about their consultative practices with the educators who serve 2e learners or how they traverse school …

Young Adults’ Metaperceptions Of Their Childhood Caregivers’ Appraisals And Young Adulthood Mental Health, Cassandra Svelnys

Electronic Theses and Dissertations

Early experiences and relationships have enduring impacts on the development of self and later mental health and wellbeing. In social relationships and interactions, the developing individual is continuously assessing how they view themself, how they view the other person, and how they believe the other person views them. Metaperceptions represent the latter construct: how an individual thinks another person perceives them. Childhood self-esteem, parent-child attachment, and metaperceptions are foundational constructs for the developing individual, yet metaperceptions have not previously been tested as a predictor for adulthood mental health while also accounting for childhood self-esteem and parent-child attachment. This study introduced …

Who Gets To Be A Child And When? The Pervasive Yet Contextually Shaped Nature Of Racialized Adultification Across Perceivers And Contexts, Kevin M. Summers

Electronic Theses and Dissertations

Racialized adultification is a pervasive bias in which individuals tend to judge Black children as older and more adult-like than White children of the same age. This racial bias is discussed across many scientific domains in addition to popular media, yet there is relatively little empirical work documenting its existence, consequences, and boundary conditions. In the current work, I aim to develop an empirical foundation that advances scientific understanding of racialized adultification and in turn contributes to a growing model that elucidates the conditions under which individuals are disproportionately likely to express this pernicious bias. In the current work, I …

Employee Engagement Strategies For Purchasing Managers, Winona L. Sewell Hall

Walden Dissertations and Doctoral Studies

The lack of employee engagement negatively impacts organizations through revenue loss, poor productivity, and toxic cultures. Purchasing managers are concerned with decreased employee engagement as it negatively impacts productivity and revenue. Grounded in situational leadership theory, the purpose of this qualitative pragmatic inquiry was to explore strategies purchasing managers use to increase engagement and productivity. The participants were six managers who have been successful in implementing strategies to increase employee engagement. Data were collected using semistructured interviews. Through thematic analysis, three key themes were identified: (a) communication, (b) leadership styles, and (c) culture. A key recommendation is for purchasing managers …

Enhancing Multi-Step Stock Price Forecasting With Social Media Sentiment And Engagement Metrics, Damilare Olaniyan

Electronic Theses and Dissertations

This thesis investigates whether social media sentiment can improve the accuracy of stock price prediction beyond traditional historical data. While financial markets have long relied on structured numerical indicators, the growing influence of public discourse on platforms like Twitter has introduced new opportunities for extracting market-relevant signals from unstructured text. The study focuses on four major technology firms and combines sentiment features derived from Twitter with historical stock prices in a hybrid machine learning framework. Engagement-weighted sentiment, linguistic complexity, and polarity intensity were extracted using natural language processing techniques and incorporated into classification and regression models. Results show that including …

Artists In The Alternative Genre: Communication Through Music, C. L. Noë

Electronic Theses and Dissertations

Musicians throughout time and genre have strived to connect with their audience through music, whether they are trying to communicate a story or their own unique style. Musicians in alternative rock genres are no different, and therefore, this thesis looks at three different bands and analyzes the ways they convey meaning through their music for their audiences. Starting with Green Day, in the American Idiot album, they communicate the inner turmoil of the characters through a rhythmic motif and the different ways it presents in the music. Next, Fall Out Boy communicates authenticity to their fans through lyrics, vocal style, …

Collaborative Federated Learning For Robots In Heterogeneous Environments, Karlan Schneider

Electronic Theses and Dissertations

This research investigates the performance of Federated Averaging (FedAvg) in simulated Federated Learning (FL) scenarios with varying degrees of environmental heterogeneity among robotic agents. The study explores the impact of data heterogeneity on both the convergence of FedAvg and the fairness of learning, with regard to consistency of performance across agents. Experiments were conducted with simulated robots trained to perform a target collection task, where a subset of agents encountered an unfamiliar environment. The results demonstrate that while FedAvg exhibits resilience to the introduction of new environmental data, it struggles to ensure both convergence and fairness in heterogeneous settings. Specifically, …

Photochemistry Of Quinones And Combustion-Derived Particles, Desiree J. Sarmiento

Electronic Theses and Dissertations

Quinones are ubiquitous species that can be produced from the photochemical aging of combustion-derived particles (CDPs). Polycyclic aromatic hydrocarbons (PAHs) are a major component of CDPs and are precursors to quinones and other oxidized products (OPAHs). My work first expanded on the PAH and OPAH photochemistry research of Dr. John Haynes, who showed that anthracene (ANT) oxidizes into 1,4-naphthoquinone (1,4-NAPQ), 1,4-anthraquinone (1,4-ANTQ), and 9,10-anthraquinone (9,10-ANTQ), and of Dr. Heather Runberg, who demonstrated the ability of ANT and these quinones to generate reactive oxygen species (ROS). Then at the Pacific Northwest National Laboratory (PNNL), I was given the opportunity to investigate …

The Role Of Adolescent Depression Heterogeneity And Resilience Resources In Adulthood Cardiometabolic Health And Depressive Symptoms, Samantha R. Scott

Electronic Theses and Dissertations

Depression in adolescence is a major public health problem and is a risk factor for early-onset cardiometabolic disease. Although adolescent depression is a risk factor for poor cardiometabolic health, depression is heterogeneous and associations may differ by sex. Additionally, if risk factors such as depression can predict adulthood cardiometabolic health, resilience factors (e.g., social, school, neighborhood) that are protective for depression may also be protective for physical health, but this is an ongoing area of research. The goals of the current dissertation were to gain a better understanding of what depressive symptom presentations in adolescents are most concerning for adulthood …

A Qualitative Examination Of Homelessness Risk Factors And Housing Histories Of Single Room Occupancy (Sro) Tenants In Chicago, Shadman Syed Saquib

College of Science and Health Theses and Dissertations

Single-Room Occupancy (SRO) housing is among the most affordable private market housing options and serves tenants who often have multiple oppressed identities, including economic marginalization, carceral histories, and disabling conditions. However, SRO buildings are often sold for redevelopment, displacing tenants with few alternative housing options and at risk of homelessness. Research suggests that multiple ecological factors, such as prior housing instability, predict future homelessness, which may be compounded for individuals with oppressed identities. Thus, the current study explores the housing histories and identities of displaced SRO tenants to understand their vulnerability to post-displacement homelessness. Seventeen participants who were displaced from …

Dataset For Cholesterol And Q147e Deamidation Modulates Aa-Crystallin Membrane Binding Elucidating Protective Role Of Lens Membrane Composition Changes With Aging, Preston Hazen, Nawal K. Khadka, Laxman Mainali

Biophysics Research Data

Purpose: αA-Crystallin (αAc) binding with lens membranes increases with age and cataract formation. However, the role of lipids and cholesterol (Chol) in Q147E-αAc membrane binding remains unclear, which we aim to elucidate in this study.

Methods: We have used the electron paramagnetic resonance spin-labeling method to probe the Chol/ 1-palmitoyl-2-oleoylphosphatidylcholine (POPC) and Chol/ sphingomyelin (SM) membranes binding with wild-type (WT) and Q147E-αAc.

Results: Compared to WT-αAc, the Q147E mutant had increased binding to POPC and decreased binding to SM membranes without Chol. Adding 33 mol% Chol to the POPC and SM membranes decreased the binding of WT and, to a …

Intersectional Resistance: German Working-Class Adaptation To Nazi Control, Nyhan O’Sullivan

Lawrence University Honors Projects

Prior to the Nazi seizure of power, the working class in Germany held political power at the local and national level. Once the Nazi state obtained control, they took decisive action and dismantle workers institutions and control the working class. The working class was forced to adapt to these rapidly changing circumstances and push back against the Nazi state in ways dictated largely by the conditions in which workers found themselves. Workers with vastly different experiences, from forced laborers to enthusiastic fascist volunteers experiences the Nazi states contempt for workers and resisted. By examining this resistance and the effects it …

Synthesis Of Anti-Schistosomal Heterocyclic Compounds Targeting Thioredoxin Glutathione Reductase, Alexander Stewart

Lawrence University Honors Projects

chistosomiasis is a deadly and debilitating parasitic disease caused by Schistosoma mansoni which affects 200+ million people annually who come into contact with contaminated water. Currently only one drug (Praziquantel) has been used to treat this disease for almost 50 years, and fear of resistance is growing, thus a new drug and new target is needed. Inhibition of the organism-specific redox defense protein Thioredoxin Glutathione Reductase (TGR) has lead to the death of the worm in vitro, indicating that it would be a good druggable target. Fragment based analysis and x-ray crystallography have returned the outline of a lead compound …

Burned In Berlin – Banned In Boston: Censorship Of Booksellers During The Interwar Period In The U. S. As Compared To Germany, 1919-1939, Aleksandra Jimerson-Mckinnies

Lawrence University Honors Projects

During the twenty-year interwar period from 1919-1939, two vastly different nations faced their own personal wars with the censorship of booksellers. Germany—at first the Weimar Republic, then later the Nazi Regime—underwent such a transformation that Berlin went from one of the literary capitals of the world to the site of the most infamous of censorship crimes: the book burnings. Meanwhile, the United States was a long-standing democratic nation in which freedom of speech was one of its cornerstone tenants. Despite the differences of governments and the scope and scale of the censorship, there were major similarities between the tactics and …

Evolutionary Conservation Of Wiskott-Aldrich Syndrome Protein In Clarthrin-Mediated Endocytosis, Jonah Friedmann

Lawrence University Honors Projects

Clathrin-mediated endocytosis (CME) is a cellular process for internalizing extracellular materials and recycling parts of the plasma membrane into intracellular vesicles. When a threshold of membrane-bound receptors is met at the cell surface, endocytic proteins organize into a conformation that can invaginate the membrane and separate a vesicle into the cytosol. Our current model for understanding CME has been derived from studies in Saccharomyces cerevisiae. Previous research has led to a model for how Las17, a homolog of Wiskott Aldrich Syndrome Protein (WASP), contributes to CME. WASP proteins are critical actin nucleators involved in multiple processes. In S. cerevisiae, Las17 …
