Sounding The Alarm: Down-Ballot Setback For The Democrats In 2020, Yaakov Huba

The Yale Undergraduate Research Journal

The 2020 general election turned out more American voters than any other election, its monumental stakes commanding the attention of the world. While the focus in the race’s aftermath has primarily been the top of the ticket, the rebuke of President Trump’s time in office, the equally important down-ballot races have been largely passed over. Many major political analysts like the Cook Political Report predicted that Democrats would expand their House majority by 5-10 seats. Yet, the Democratic Party ended up losing 10 seats1. During the certification of election results, I collected data on incumbents in the US House of …


Optimal Information Design In Two-Sided Trade, Pradhi Aggarwal Aug 2021

Optimal Information Design In Two-Sided Trade, Pradhi Aggarwal

The Yale Undergraduate Research Journal

In a two-sided market with a broker, the broker can influence the buyer’s and seller’s optimal trading behaviour through strategic information design. We study the impact of information about waiting times on riders and drivers in a rideshare market. We consider three information regimes: the first in which no information about time is revealed, the second in which true waiting times are communicated, and finally an intermediate regime in which agents are only told whether their waiting time falls within a high or low category. We evaluate the optimality of each information regime by maximizing welfare and revenue for each …


Current State Of Seagrasses In Zanzibar: Impacts Of Coastal Economic Activities And Marine Protected Areas On Seagrass Cover, Danielle Purvis, Narriman Jiddawi Aug 2021

Current State Of Seagrasses In Zanzibar: Impacts Of Coastal Economic Activities And Marine Protected Areas On Seagrass Cover, Danielle Purvis, Narriman Jiddawi

Capstone Collection

Seagrass meadows are located abundantly in Zanzibar, Tanzania and provide essential ecosystem services, such as sediment nutrient enrichment and blue carbon sequestration. However, seagrasses have been less researched or protected than other marine ecosystems. Although environmental variables affect seagrass health, evidence suggests that anthropogenic impacts are their greatest threats. The rapid expansion of seaweed farming and tourism and widespread use of harmful small-scale fishing practices in Zanzibar have contributed to the degradation and removal of seagrass meadows, disrupted coastal marine food chains, and reduced local biodiversity that seagrasses support. Public or private marine protected areas (MPAs) protect most of Zanzibar’s …

Forensic Artifact Finder (Forensicaf): An Approach & Tool For Leveraging Crowd-Sourced Curated Forensic Artifacts, Tyler Balon, Krikor Herlopian, Ibrahim Baggili, Cinthya Grajeda-Mendez

Electrical & Computer Engineering and Computer Science Faculty Publications

Current methods for artifact analysis and understanding depend on investigator expertise. Experienced and technically savvy examiners spend a lot of time reverse engineering applications while attempting to find crumbs they leave behind on systems. This takes away valuable time from the investigative process, and slows down forensic examination. Furthermore, when specific artifact knowledge is gained, it stays within the respective forensic units. To combat these challenges, we present ForensicAF, an approach for leveraging curated, crowd-sourced artifacts from the Artifact Genome Project (AGP). The approach has the overarching goal of uncovering forensically relevant artifacts from storage media. We explain our approach …

Electrical & Computer Engineering and Computer Science Faculty Publications

We present a comprehensive review of digital forensics programs offered by universities across the United States (U.S.). While numerous studies on digital forensics standards and curriculum exist, few, if any, have examined digital forensics courses offered across the nation. Since digital forensics courses vary from university to university, online course catalogs for academic institutions were evaluated to curate a dataset. Universities were selected based on online searches, similar to those that would be made by prospective students. Ninety-seven (n = 97) degree programs in the U.S. were evaluated. Overall, results showed that advanced technical courses are missing from curricula. We …

Qualitative Review Of Educational Interventions For Improving Physical Activity Behaviors In Older Asian Americans In The United States, Raisa Kabir, Manoj Sharma, Sayeda Tazim Zaidi, Chia-Liang Dai

Spectra Undergraduate Research Journal

Physical activity (PA) provides numerous health benefits and minimizes chronic diseases and mental health issues, especially in older adults. The national survey data indicated that only 27.3% to 44.3% of older adults meet the recommended PA guidelines of 150 to 300 minutes/ week. There is limited data on PA behavior among older Asian American (AA) adults as very few to no local/national surveys have targeted these marginalized subgroups. This comprehensive review aims to identify existing PA intervention strategies and to update current knowledge on the effectiveness of these interventions to improve PA behavior among aging AA in the US. The …


The Future Of The Live Entertainment Tax In Southern Nevada, Katie M. Gilbertson Aug 2021

The Future Of The Live Entertainment Tax In Southern Nevada, Katie M. Gilbertson

Spectra Undergraduate Research Journal

The Live Entertainment Tax (LET) in Nevada generated nearly one billion dollars during the 2019-2020 fiscal year. LET revenue all goes to the State General Fund, even though 97 percent of LET revenue is generated in Clark County. Nevada is experiencing an economic crisis, particularly in the tourism industry. Solutions from various fields suggest the best way to boost the local economy is to reinvest revenue in its original county. One policy solution Nevada policymakers should consider is to carve out a percentage of revenue generated by the LET to return directly back to Clark County to revitalize tourism.

Spectra Undergraduate Research Journal

Alzheimer’s disease (AD) degrades the brain’s ability to remember, think, and carry out tasks. The exact cause is not known, but several risk factors have been identified, including diabetes mellitus (DM). DM causes elevated blood sugar levels due to reduced insulin production in the pancreas. The linkage between elevated glucose levels and the behavioral impairments are not fully understood, which was the focus of this study. Rats were trained to alternate directions in a maze to receive a reward on consecutive trials. After training, five rats were injected with streptozotocin (STZ), which induces hyperglycemia by injuring pancreatic beta cells. Three …


A Timeline Of Discovery And Current Research On Primary Open-Angle Glaucoma And Emergence Of Potentially Permanent Treatment Solutions, Yonosuke Dejesus, Guadalupe Moreno Ceballos Aug 2021

A Timeline Of Discovery And Current Research On Primary Open-Angle Glaucoma And Emergence Of Potentially Permanent Treatment Solutions, Yonosuke Dejesus, Guadalupe Moreno Ceballos

Spectra Undergraduate Research Journal

This research examines the timeline of the discovery and research of Primary Open-Angle Glaucoma (POAG). By reviewing the literature on genetic and molecular mechanisms, we aim to emphasize a long-term treatment solution (iSTENT) to mitigate intraocular pressure (IOP) related to POAG etiology and disease progression. POAG is a multifactorial, autosomal dominant, adult-onset eye disease wherein the optic nerve cells become damaged due to a buildup of excess aqueous humor, resulting in increased IOP. Consequently, POAG leads to progressive loss of peripheral vision and is the leading cause of blindness in the US. Due to the multifactorial nature of glaucoma’s inheritance …


Racial Profiling: Understanding The Practice Of Stop-And-Frisk In New York City, Lisa Ly Aug 2021

Racial Profiling: Understanding The Practice Of Stop-And-Frisk In New York City, Lisa Ly

Spectra Undergraduate Research Journal

Racial profiling has become a prominent issue in modern policing today. Instead of being based on individual suspicion, racial profiling embodies a belief that people of color are continuously singled out by the police for scrutiny and harassment. Policies and procedures make the Black community vulnerable to police discrimination and racial profiling. Floyd et al. v. City of New York et al. (2013) declared that the New York Police Department’s (NYPD) practice of stop-and-frisk was racially profiling Black civilians. This study sought (1) to determine if the NYPD post-Floyd is still engaging in racial profiling towards Black civilians; and (2) …
