An Analysis Of Associations Between Polarimetric Supercell Signatures, Erik Green

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Supercell thunderstorms produce unique polarimetric radar signatures that are not often observed in unorganized deep convection. Repetitive signatures include deep and persistent differential reflectivity (Z_DR) columns and the Z_DR arc signature, which are both indicative of thermodynamic and microphysical processes intrinsic to supercells. Prior investigations of supercell polarimetric signatures, both those observed by operational and research radars, and those simulated numerically, reveal positive correlations between the Z_DR column depth and cross-sectional area and quantitative characteristics of the radar reflectivity field. This study expands upon prior work by incorporating a dataset of discrete, right moving supercells …

Settler Colonial Origins Of Intimate Partner Violence In Indigenous Communities, Maia C. Behrendt

Department of Sociology: Dissertations, Theses, and Student Research

Indigenous women in the United States experience disproportionately higher rates of intimate partner violence (IPV) compared to their non-Indigenous counterparts. Through a framework of settler colonialism, this article examines how settler colonial gender practices disrupted and eroded generational patterns of gender roles and power relationships within Indigenous communities, contributing over time to today's higher levels of IPV perpetrated against Indigenous women. I argue that future research on IPV must attend to the historical, contemporary, and legal impacts of settler colonial policies and laws that contribute to increased rates of violence within marginalized and racialized communities. In this article, I first …

Wasted Intuitions: New York City’S Solid Waste Management System And The Ambiguous Effects Of Traditional Collective Good Provision Analysis, Andrew Asplin

Honors Program: Senior Projects (Public)

Refuse Collection services' status as a public good has been highly contested. As it is both rivalrous and excludable, basic theory predicts that private provision of solid waste management services will be more efficient. Private trash carters are able to specialize in a way that municipality-run services simply cannot. New York City is unique in that its solid waste management system is rigidly split: residential trash is managed by the city; commercial trash is managed by private businesses. This thesis explores how New York City's public and private solid waste management systems complicate these initial intuitions through a welfare analysis. …

Turning Back Time: Implications Of Originalist Legal Theory For Women's Rights, Emma Mays

Honors Program: Senior Projects (Public)

Since America’s foundation, women’s rights have expanded to lengths that would have been unimaginable to the Founding Fathers including the right to vote, the ability to work outside the home, and some aspects of bodily autonomy. These legal adaptations, along with a larger cultural shift towards liberation, have left many modern-day women with a false sense of security in the face of growing judicial sentiments that threaten the rights of women. The legal theory of originalism that has been growing in force significantly since the 1980s argues that in interpreting constitutional matters, judges should uncover and promote the meaning of …

Safety Splash: Pool Safety For Children And Adults, Rachel Lofton

Honors Program: Senior Projects (Public)

This outreach project was made to address the issue of too many children drowning at pools due to a lack of water safety education. The dissemination of pool safety education is imperative to reduce accidental injuries and drownings. The goal of the Safety Splash video and supplemental materials is to provide pool safety education for children and adults.

The Green Wave: Effects Of Legal Marijuana On The Labor Market., Sara Varon

Honors Program: Senior Projects (Public)

In this paper I examine the relationship between the introduction of recreational marijuana laws and the labor market. First, using Google Trends data I find evidence that states that undergo the treatment of recreational marijuana legalization will likely experience a large and significant increase in search volume terms related to marijuana demand following the implementation of marijuana regulations. Using this same data set, I find support for the theory that as marijuana legalization becomes more entrenched within each individual state, public interest for marijuana also increases which allows for the use of Google Trends data as a proxy for legalization …

Biochar: Properties And Potential Benefits For Agricultural Soil In Rwanda, Andromede Uwase

Honors Program: Senior Projects (Public)

Physical and chemical soil degradation is becoming a major challenge for agricultural productivity in Rwanda, which is the most important part of the country’s economy. The wide spreading soil degradation in Rwanda is mainly a result of naturally poor soils coupled with unsustainable soil management leading to, for example, accelerated soil erosion, acidification, nutrient loss, compaction, and to decreasing yields. Biochar, as an end product of pyrolysis of biomass in the absence of oxygen, has been proposed as a soil amendment in remediation strategies because of its positive effects on soil productivity relevant parameters such as soil pH, structure, nutrient …

Targeting Transgenic Proteins To The Mitochondria In Plants, Susan Qudus, Jeffrey P. Mower

Honors Program: Senior Projects (Public)

Cytoplasmic male sterility (CMS) in plants can convert an individual into female through sterilization of the male reproductive parts, creating an inability to produce functional pollen. In nature, this is advantageous for genetic diversity and producing progeny with unique genes that may be beneficial in evolution. For agriculture, this method is preferential for selection of desirable traits in crops when cross breeding. CMS is typically caused by genes in the mitochondrial DNA (mtDNA), such as novel open reading frames (ORFs) that form after imperfect repair of double-stranded breaks in the mtDNA. Specific CMS genes vary among various plant species. It …
