The Sharing Economy And Urban Crime, Bryan S. Weber

Publications and Research

This paper examines whether the intensity of Airbnb is associated with city-level crime rates. This research sheds light on matters adjacent to current activities in public policy as cities engage in city-level Airbnb regulation. At the same time, Airbnb continues to expand. In the aggregate, Airbnb usage is associated with no significant crime increase but rather significant decreases in crimes of private conflict that persist in direction, significance, and magnitude over time. I do uncover evidence that two types of rooms, private rooms (44%) and shared rooms (1.5%), appear to be positively associated with both property crimes and crimes against …

Mental Health Stigma Related To Depression And Suicidal Behavior In Korean-Americans, Soo Min Kim

Student Theses

Despite the surge of the Korean population within the United States, the Korean-American population is significantly underrepresented in research when observed separately from other Asian groups. The Republic of Korea has had the highest suicide rate within the OECD nations for well over a decade (Organization of Economic Cooperation and Development), and evidence suggests that the risk of suicidality may extend to Koreans living abroad (Kung, 2018). There is also evidence of high prevalence of depressive symptoms in Korean-Americans (Bernstein et al., 2011). In addition, Koreans are consistently demonstrated to hold stigmatizing beliefs about mental illness, however, very little research …

An Investigation Of Continued Contact Between Victim And Perpetrator After Sexual Violence, Maria Bates

Student Theses

Given the prevalence of sexual violence and child sexual abuse (CSA) it is imperative to accurately conceptualize victim experience following sexual violence. Rape myths do not provide an adequate understanding of victim behavior post-abuse/assault (e.g., Denne et al., 2013; Harsey & Freed, 2023; Romero-Sanchez et al., 2018; Russel & Hand, 2017), such as prescribing that victims of sexual violence would never hold contact with a perpetrator post-abuse/assault (e.g., Maurer, 2015; Shepp et al., 2019; St. George et al., 2022; Smith, 2023). Since research shows that many victims, particularly CSA victims, know the perpetrator, (e.g., Basile, 2020; Gewirtz-Meydan & Finkelhor, 2020; …

Human Trafficking Screening Tools Amongst Migrants And Refugees: Current Tools And Future Outlooks, Audra Fox

Student Theses

While various human trafficking screening tools exist to help stakeholders identify indicators and risk of trafficking, few tools are designed specifically for use amongst migrants and refugees. Via interviews with anti-trafficking stakeholders, the following qualitative study describes what tools stakeholders currently use to asses trafficking amongst migrants and refugee, and if stakeholders desire a new tool specific for migrant/refugee populations. Thematic results indicate that most stakeholders are not using validated tools for trafficking victims, let alone migrants and refugees (n=5, 38.5%). Of the total sample, 62% of participants (n=8) reported various screening discrepancies across stakeholders. Additionally, …

Enhanced Rate Capability And Capacity Of Lib Full Cells Achieved Through Aerosol Jet Printing, Rodrigo Rodriguez, L. Jay Deiner, Bang-Hung S. Tsao, Joseph P. Fellner

Publications and Research

Thick lithium-iron phosphate (LFP) cathodes (31 mg cm−2) with rationally engineered pore structure and tortuosity were manufactured with an aerosol jet (AJ) printer. Cathode pore structuring was tuned by controlling the rate at which the printed ink dried. Slow-drying prints yielded smoother cathodes while fast-drying prints resulted in mesoscale structuring with substantial surface roughness. X-ray tomography further revealed that the rapid drying of AJ printed LFP cathodes produced low-tortuosity pore channels which were preserved after calendering. Full cells comprised of AJ print optimized LFP cathodes, with 30 mg cm−2 active material loadings, and capacity-matched, AJ printed lithium titanate anodes were …

Through The Digital Lens: Examining Beliefs About Online Child Sexual Abuse, Kendhyl Delacour

Student Theses

Child sexual abuse (CSA) is a global societal problem. Advances in technology and widespread Internet access have shifted much of the focus and prevention policies toward online CSA (OCSA). Initially, internet crimes against children were seen as “stranger danger” offenses, where the perpetrator was unknown to the victim. However, recent studies show that online sex offenses are mostly committed by individuals known to the victim. While existing literature has explored how the “stranger danger myth” shapes public perceptions about in-person offenders, little is known about public beliefs regarding OCSA within the context of the stranger danger myth. This study aimed …

Use Of Population-Weighted Density Index For Coronavirus Spread In The United States, Huseyin Yuce, Hannah Stauss, Adrienne Persad

Publications and Research

Background: Understanding how population density affected the transmission of COVID-19 is vitally important, since crowded cities were the epicenters for the disease. Since human contact was the main cause of the spread, population-weighted densities have been shown to be a better measure than conventional densities, since the variation in density across subareas matters more than the density in the total area. Objectives: This study investigates the impact of population-weighted density and other demographics on the rate of COVID-19 spread in the United States. Methods: The study considers population-weighted density and many other demographics. The population-weighted density index is the weighted …

‘A Storm Is Coming:' The New York Times Coverage Of The Covid-19 Pandemic In American Prisons, Katarzyna Celinska, Amina Cheboubi

Publications and Research

In this research, we analyzed the content of 171 articles published between March and August 2020 in the New York Times (NYT) on COVID-19 in American correctional institutions. We observed that the NYT coverage decreased significantly over 6 months. Our analysis uncovered 8 themes within two broader frames: institutional and systemic inequity. Although the themes are not mutually exclusive, we argue that ‘Responding to COVID-19,’ ‘A storm is Coming,’ ‘Collective Experience,’ and ‘Critiquing Prison Conditions’ are within the institutional framing. ‘Redefining Public Safety,’ ‘Categorizing Prisoners,’ ‘Doing Injustice,’ and ‘Making it as a Celebrity’ are the themes that highlight systemic inequity, …

Frontera De Valldemosa’S Equinotación And The Nineteenth-Century Textbook Controversies It Sparked, Antoni Pizà

Publications and Research

Abstract:

Francisco Frontera de Valldemosa (1807-1891) published the first edition of his treatise, generally known as Equinotación, in 1837. The book purported to simplify musical notation by reducing the complex system of clefs to only three. From the moment it became public his clef method became controversial. First, it sparked a long controversy in the Revue et gazette musicale de Paris regarding the system’s originality, usefulness, and possible plagiarism. Subsequent editions decades later also sparked debates and even a couple of lawsuits, as reflected in several articles in the Gaceta musical barcelonesa. At the bottom of these polemics …

Entrypoints For Integrating Computing And Tech Into Teacher Education: Addressing Problems And Opportunities With The Encite Framework, Sara E. Vogel, Aman Yadav, David Phelps, Aankit Patel

Publications and Research

To coherently integrate computing and digital technology into teacher education, stakeholders at teacher preparation institutions must grapple with a complex landscape of problems and opportunities. This paper’s literature review maps that landscape into problems and opportunities that are (1) technological, (2) pedagogical, definitional / (3) ideological, (4) political, and (5) developmental in nature. While existing frameworks respond to particular aspects of these areas (e.g. the popular TPACK framework zooms in on technological and pedagogical questions), stakeholders engaged in curricular planning must think more holistically about how to prepare future teachers. We share EnCITE (Entrypoints to Computing Integrated Teacher Education), a …

Attribute-Based Fine-Grained Access Control Using Verifiable Credentials, Srinivasa Dumpa

Student Theses

In the era of digital transformation, ensuring secure and privacy-preserving access control mechanisms is of paramount importance. Traditional identity-based access control systems often fall short in providing granular control and user autonomy over digital identities. This thesis presents a novel approach to access control by leveraging the power of verifiable credentials and attribute-based access control. The proposed system introduces a decentralized and user-centric framework that enables fine-grained access control based on specific attributes encapsulated within verifiable credentials. These tamper-evident digital credentials, stored in a user's digital wallet, contain a rich set of attributes that can be selectively disclosed to grant …

How Do Teachers Make Sense Of New Learning About Culturally Responsive And Sustaining Education?, Kristine Mustillo

Student Theses

The education of Black citizens has historically been unequal and plagued with deficit based approaches that result in the under-education and over-disciplining of Black youth in schools, with dire implications. Culturally Responsive and Sustaining Education (CRSE)aims to change the narrative by honoring the racial, ethnic, linguistic and cultural differences of students of color who are marginalized in a school curriculum, featuring a pedagogy that empowers students (Ladson-Billings, 2021). Educators often report that they understand CRSE in theory but there is confusion when putting the theory into action and there are other challenges faced when working in current social and political …
