Sales Of Cage-Free Eggs: The Impact Of Proposition 12 On Egg Prices And Consumer Welfare In California, Mingcong Xie

The Journal of Purdue Undergraduate Research

California’s Proposition 12, which outlaws the use of cages in the egg production process, went into effect on January 1, 2022. The main focus of this study is to follow the trend of weekly Californian and national egg price changes before and after the implementation of Proposition 12. Using the price series reported by the United States Department of Agriculture (USDA), structural break tests and Ordinary Least Squares (OLS) regressions are carried out to directly measure the economic impacts of this new regulation on egg prices. With different models used, this study shows that California consumers now pay an additional …

Biodiesel Transesterification Of Spent Coffee Grounds Using Dbu As A Catalyst: Using Dbu To Make Biodiesel From Coffee Grounds, Christopher Stepherson, Pericles Karras, Amy Ha, Phuc Tan Nguyen, Abigail Pati, Jacob Hejazi, Soheil Hussain, Elizabeth De Young, Shuaicheng Fu

The Journal of Purdue Undergraduate Research

Coffee is one of the most universally consumed beverages. The world produces 60 million tons of spent coffee grounds (SCGs) as waste per year. Biodiesel made from SCGs is an eco-friendly alternative fuel but proves difficult to produce. 1,8-Diazabicyclo[ 5.4.0]undec-7- ene (DBU) was used as both a solvent and a catalyst with methanol to determine the efficiency of biodiesel production from SCGs. The process was completed by extracting coffee oil from acid-washed spent coffee grounds (AWSCGs) using hexane. The two extraction methods that were explored were Soxhlet and agitation. DBU is an interesting choice as a solvent and a catalyst …

The Role Of Vocal Development Patterns: Predicting Neurogenetic Risk In Infancy Using Early Vocal Development And Sex, Alyssa Cregg, Rachel Siela, Olivia Battaglia, Kaylee Bobay, Madison Chin, Athena Fordwor, Conghao Gao, Deeksha Handa, Erin Lee, Tiernan Mcdivitt, Grace Strabala, Victoria Tuell, Laurel Williams

The Journal of Purdue Undergraduate Research

Extant literature documents a higher rate of language/speech disorders in males; however, despite sex being a potential moderator of outcomes, we do not know what role it plays in early vocal behavior of infants at high risk for such disorders. The purpose of this study was to ask: (1) Do high-risk infants demonstrate atypical vocal development patterns? (2) Is the quality and quantity of early babble distinct for male and female infants, and does this pattern vary across risk? To answer these questions, we examined the canonical babbling ratio (CBR; the ratio of canonical syllables, those with a consonant and …

Trauma, Recovery, And Adolescent Relationships In Stephen Chbosky’S The Perks Of Being A Wallflower: An In-Depth Analysis, Rachel Rosen

The Journal of Purdue Undergraduate Research

The development of adolescent identity after traumatic experiences is a fragile process. In this essay, I use Stephen Chbosky’s The Perks of Being a Wallflower (1999) to explore how adolescent relationships influence the path to recovery after traumatic experiences. After losing both his friend and aunt, Charlie, the novel’s protagonist, begins to write letters, which form the basis of the book. Recounting his journey to recovery, these letters ultimately reveal that Charlie’s aunt molested him when he was a child—a memory that he represses for years. Despite the importance of writing as a way for Charlie to cope with this …

Genome-Wide Mutagenesis To Investigate The N-Terminal Methylome: The Protective Effects Of Hsp31 And Other Methylated Proteins In Yeast, James Rooney, Jacob Lindsey

The Journal of Purdue Undergraduate Research

The purpose of this study was to understand the role of methylation in regulating the cellular stress response of Hsp31 in Saccharomyces cerevisiae yeast cells. Hsp31 is known to be methylated by the N-terminal methyltransferase Tae1. Changing the methylation site can affect the methylation status of Hsp31, which may play a role in the protective activity of Hsp31 against cellular stress. GLO1 is a gene in yeast involved in catalyzing the detoxification of methylglyoxal (MGO), which is a by-product of glycolysis. We established that S. cerevisiae in the glo1Δ and background is sensitive to cellular stress by MGO. Mutant strains …

Machine Learning Of Big Data: A Gaussian Regression Model To Predict The Spatiotemporal Distribution Of Ground Ozone, Jerry Gu

The Journal of Purdue Undergraduate Research

Tracking pollution levels on the ground is important to the environment and public health. One of the pollutants of concern is ozone, which, at high concentrations, can cause respiratory and cardiovascular problems. The National Center for Atmospheric Research (NCAR) has published valuable ozone data obtained from ground-based sensors installed at selected locations. Because it is unfeasible to measure the exact ozone levels everywhere at any time, it would be valuable to predict the temporal-spatial distributions of ozone concentration based on existing data. This would help us better understand the patterns and trends in the data and make better decisions to …

A Computational Profile Of Invasive Lionfish In Belize: A New Insight On A Destructive Species, Joshua E. Balan

The Journal of Purdue Undergraduate Research

Since their discovery in the region in 2009, invasive Indonesian-native lionfish have been taking over the Belize Barrier Reef. As a result, populations of local species have dwindled as they are either eaten or outcompeted by the invaders. This has led to devastating losses ecologically and economically; massive industries in the local nations, such as fisheries and tourism, have suffered greatly. Attempting to combat this, local organizations, from nonprofits to ecotourism companies, have been manually spear-hunting them on scuba dives to cull the population. One such company, Reef Conservation Institute (ReefCI), operating out of Tom Owens Caye outside of Placencia, …

Parentally Exposed Zebrafish Larvae Have Altered Craniofacial Measurements: Multigeneration Developmental Atrazine Toxicity, Isabelle Akoro

The Journal of Purdue Undergraduate Research

Atrazine is a herbicide used throughout the midwestern United States to prevent broadleaf weeds in crops. The U.S. Environmental Protection Agency (EPA) has set the maximum contaminant level at 3 ppb (μg/L) in drinking water. Atrazine is an endocrine disrupter interfering with the function of hormones and disrupting normal physiology and homeostasis throughout development and the life course of an organism. The zebrafish model was used to test the hypothesis that an embryonic parental atrazine exposure will cause modifications in morphology in developing offspring. AB adult zebrafish were bred. Embryos were collected and exposed to atrazine concentrations of 0, 0.3, …

“Help Is Here”: How A Daca Pathway To Citizenship Will Help Save The Social Security Fund, Jissel Esparza

Arkansas Law Review

Two federal programs hold their beneficiaries in limbo: DACA and Social Security. This Comment demonstrates that creating a citizenship pathway for the DACA population will not only give these deserving individuals the ability and security to remain in the United States but will also provide relief to Social Security’s impending insolvency through the influx of taxes that these then citizens will contribute as a result of increased opportunities. At the same time, this Comment does not attempt to portray its argument as a “silver bullet.” Rather, this approach is one tool that can be utilized by legislative efforts to remedy …

Wanted: A Prudential Framework For Crypto Assets, Lee Reiners, Sangita Gazi

Arkansas Law Review

This Article summarizes the limited publicly available data on banks’ exposure to crypto assets and offers several specific examples of how U.S. banks engage in crypto-related businesses. It then examines past guidance issued by U.S. bank regulators and explains why this guidance lacks sufficient detail to clarify the prudential requirements associated with the various crypto-related activities in which banks are engaged. The Article then assesses the adequacy of the Basel Committee on Banking Supervision’s final prudential standard for crypto-asset exposures, issued in December 2022, and finds that the measure fails to adequately address the unique risks various crypto-asset activities pose …
