Evolving Discipline Strategies: The Effects Of Police Removal On School Discipline In San Francisco, Eliza Grace Giroux

Master's Projects and Capstones

As conversations about equity and student well-being continue to shape public education, longstanding approaches to discipline in schools are being reevaluated. One major area of focus has been the presence of police on school campuses, especially when punitive systems have disproportionately harmed marginalized students. In San Francisco, this shift culminated in the 2020 passage of Resolution 206, which formally ended the school district’s partnership with the San Francisco Police Department and removed armed officers from campuses. This capstone examines the impact of that decision by exploring how school discipline practices have changed in the years since. Through interviews with members …

Theses and Dissertations

The objective of this research was to investigate the biopreservative effects of chitosan and lemon essential oil in slush ice treatments on the microbial shelf life of refrigerated catfish fillets. Catfish fillets were stored in slush ice treatments containing chitosan (CH), lemon essential oil (LO), a combination (CH+LO), water (CTRL), and no slush (NS) for three d at 4 C, then stored at 4C for twelve d post-slush. The growth of background microflora in catfish fillets treated with CH and CH+LO was reduced (P<0.05), maintaining total aerobic counts below 4.5 log CFU/g, while the control reached spoilage levels (>7 log CFU/g) by Day 6. Chitosan effectively extended the microbial shelf life but lowered pH, …

Effects Of Different Forms Of Dietary Zinc On Weaned Steers When Fed Prior To Weaning, Christopher Lane Addison

Theses and Dissertations

Zinc (Zn) is crucial for many life sustaining processes within the body. Additional Zn is known to be beneficial during certain periods of increased stress. Weaning is one of the most stressful periods of beef calves’ lives. Due to this it was hypothesized that additional zinc in an organic form would increase weight gain and immune response compared to additional zinc in an inorganic form or no added zinc. No differences were found for ADG, Th score, IgG concentration, or mineral concentration among treatments. However, there was a novel and unexpected finding when there was no difference found in preweaning …

Evaluation Of Plant Growth Regulators On Sweetpotato Slip Propagation, Kerington Lyn Bass

Theses and Dissertations

Sweetpotato production is often impacted by high mortality of slips during transplantation to the field, particularly with greenhouse-grown slips. These slips develop thinner stems, thus being more vulnerable to transplant shock, resulting in reduced establishment. To address this issue, the study evaluated the effects of four plant growth regulators on the morphological and anatomical characteristics of sweetpotato slips. In the first experiment, external growth parameters were recorded over four weeks, followed by post-harvest assessments of plant and root material. In the second experiment, the widths of various stem structures in stained cross-sections of slip stems were measured. Results showed that …

The Effects Of Ataxin-1 Overexpression In The Central Nervous System On Specific Behavioral And Physiological Characteristics Of Drosophila Melanogaster, Sydney Davis

Theses and Dissertations

Spinocerebellar ataxia type 1 (SCA1) is a dominantly inherited neurodegenerative disease caused by a CAG repeat expansion in the ataxin-1 gene, which results in an abnormally long polyglutamine tract. Similarly, overexpression of wildtype Ataxin-1 (wt-Atx-1) in Drosophila melanogaster leads to neurodegeneration, reduced lifespan, and impaired negative geotaxis. Observations include disruptions in sleep-wake cycles, increased oxidative stress biomarkers (like protein carbonyls), and dysregulation of developmental genes such as armadillo (arm) and nemo kinase (nmo). Additionally, elevated expression of SUMOylation-related genes (Aos-1, Uba2, and dSmt3 or dSumo) and increased SUMO protein levels indicate enhanced SUMOylation in the brain. Quantitative analysis of neuronal …

Assessment Of Pagp Gene Function In Avian Pathogenic Escherichia Coli Pathogenicity Using Different Challenge Models, Hailey Fugate

Theses and Dissertations

Avian pathogenic Escherichia coli (APEC) is a leading cause of morbidity and mortality in poultry, contributing an estimated $40 million in annual losses in the U.S. broiler industry alone, and contributing to growing concerns over antibiotic resistance. This study investigated the role of the pagP gene, which encodes a lipid A palmitoyl transferase involved in immune evasion, using both a broiler chick and embryo challenge model. Deletion of pagP significantly reduced mortality and lesion severity in broilers, indicating its role in APEC pathogenicity. However, in embryos, pagP deletion had minimal effects on survival and bacterial colonization, suggesting alternative virulence mechanisms …

Theses and Dissertations

The dairy industry has increasingly prioritized improving animal welfare for intensively housed cows. This study evaluated the effects of environmental enrichment (EE) using an automated brush system on stress physiology, behavior, and productivity of lactating dairy cows. Fifty-nine pregnant and lactating dairy cows were divided into two groups: CON (no brush) and TRT (automated brush system). Saliva samples were collected to measure cortisol concentrations, and behaviors were monitored in the morning (07:00 h - 11:00 h) and evening (19:00 h - 23:00 h) using high-resolution cameras. The results indicated that cows with brush access had lower cortisol concentrations, suggesting reduced …

Exploring Sexual Dimorphism In A Drosophila Melanogaster Model Of Spinocerebellar Ataxia Type 1, Madelyn Hunter

Theses and Dissertations

Neurodegenerative diseases affect over 36 million people and are characterized by loss of motor control, neuronal degradation, and behavioral changes. The most common of these diseases exhibit sexually dimorphic effects. In this study, Spinocerebellar ataxia type 1 (SCA1) was modeled in the Drosophila central nervous system using the yeast hybrid UAS/GAL4 system. Locomotor activity and clock gene expression was monitored for male and female SCA1 and control flies. Clock genes such as per, tim, Clk, and cyc were monitored over a 24-hour period using qRT-PCR, and distinct sexual dimorphism was detected in locomotor activity and in gene expression for SCA1 …

Evaluating The Use Of Translucency Score As An Effective Parameter Of Eggshell Quality, Cassidy Autumn Morris

Theses and Dissertations

The objective of this thesis was to determine if an egg’s translucency score (TS) could be used as an effective predicting parameter to determine eggshell quality in both broiler breeders and commercial laying hens. In broiler breeders, it was determined that TS could be used as an effective predicting parameter for eggshell thickness (P< 0.001) and L* scores (P< 0.001). It was also found that the supplementation of organically sourced trace minerals could significantly decrease the TS of eggs, resulting in a better-quality eggshell (P< 0.001). In two different aged commercial laying hen experiments, there was no conclusive evidence for TS to be a predictive parameter of eggshell quality throughout the storage period. It was found, however, that the storage period did significantly increase the TS throughout storage in both experiments (P< 0.001).

Impact Of Fertilizer Timing And Cover Crop Establishment Methods On Bedded Soybean Cropping Systems In Mississippi, Grant Madison Shavers

Theses and Dissertations

Mississippi’s agriculture faces challenges from high rainfall, bedded cropping systems, and varying soil testing methods. Many producers apply phosphorus (P), potassium (K), and sulfur (S) in the fall to reduce spring workload and rain-related delays. While fall fertilization raises concerns about yield losses, research indicates minimal differences in soybean (Glycine max L.) yield between fall and spring applications. Raised beds also limit cover crop (CC) establishment despite their potential benefits. We explored strategies to integrate CCs into bedded systems while assessing bed stability and residue management during soybean production. Additionally, Mississippi’s use of two soil nutrient extraction methods highlights the …

Effects Of Environmental Stress And Antimicrobials On The Health, Microbiome, And Product Shelf-Life Of Channel And Hybrid Catfish, Guyue Tang

Theses and Dissertations

Two studies investigated various aspects of channel and hybrid catfish production and processing. The first study examined the effects of ammonia stress (15 mg/L vs. 1 mg/L control) on growth performance and fillet quality. While channel catfish demonstrated superior growth, ammonia stress minimally impacted the sensory profiles of both species. Gut microbiota analysis revealed species-specific differences, with Lactococcus lactis dominating hybrid catfish communities. The second study evaluated buffered vinegar treatment (1.5%) on fillet shelf life during refrigerated storage. Vinegar-treated fillets maintained better microbiological quality, with aerobic plate counts remaining below 7 log cfu/g through day 6, while untreated fillets exceeded …

Climate Change Anxiety And Hope Both Predict Action: A Moderation Analysis, Yuhan Bi, Grace Hyde, Orei Z. Odents, Kai Okagawa, Cassandra Hoffman, Kimberly A. Barchard

Spectra Undergraduate Research Journal

Climate change is associated with extreme weather events that have devastating effects on communities worldwide. These events disrupt ecosystems, damage infrastructure, and influence physical and mental well-being. Urgent action is needed. Prior studies demonstrate that people are more likely to take action if they feel anxious about climate change and if they feel hopeful they can make a difference. However, we hypothesized that anxiety and hope would interact: that anxiety would only predict action when people felt hopeful. Therefore, we used path analysis to determine if hope moderates the relation between anxiety and action.

In a cross-sectional design, 500 United …
