- Women in STEM Fellowship: An Intersectional and Interdisciplinary Approach
to Advancing Inclusion in the Sciences
Authors: Ina C. Seethaler et al.
Abstract: At our university, women-identified individuals make up 23% of students in STEM fields; less than 15% of them graduate with a STEM degree. Nationally, more than 40% of women who enter a STEM job leave it within fewer than ten years. Gendered issues within STEM industries have been identified, yet we are far from equal opportunities for all genders. In 2018, we—the director of Women’s and Gender Studies (WGS) with colleagues in Math, Computing Sciences, and Chemistry—received a $45,000 grant to create a “Women in STEM Fellowship.” The inclusion of WGS made the fellowship interdisciplinary, intersectional, and informed our decision-making process via feminist diversity, equity, and inclusion approaches. Through WGS approaches to questioning oppressive systems as well as a community-building focus, we attempted to mitigate prevalent reliance on neoliberal individualism.This article offers insights into the fellowship's activities and programs, challenges and successes, as well as assessment. We call on diversity initiatives in STEM to collaborate with academic and student success units—such as WGS or Black Studies—that house much-needed expertise and to refrain from isolating efforts in STEM departments.

- Intramolecular Friedel-Crafts Addition of Indoles to Tertiary Allylic
Alcohols
Authors: Bryan H. Wakefield et al.
Abstract: An intermolecular Friedel-Crafts alkylation of indole and tertiary allylic alcohols has been developed. The allylic alcohols were synthesized using a two-step procedure, then exposure of these alcohols to diphenyl phosphate facilitated the desired annulation reaction. This reaction tolerated a variety of indole substitutions to yield 1H,2H,3H,4H-pyrido[1,2-a]indoles.

- The Planted Catalog: The Role of the Botanical Garden in Botany
Authors: Douglas Tuers
Abstract: This article will investigate the role of the botanical garden in botany. What its role is and how it fills it. This article will take the Missouri Botanical Garden as a case study, drawing heavily from archival material compromised mostly of letters between Henry Shaw and the prominent botanists of his day. This study also draws on the prominent histories of the Missouri Botanical Garden. The analysis use the philosophical tradition around reference in logic and language. This study argues that the botanical garden is a bridge between locality and herbaria. The order of the flora travels to the locality and the wildness of the locality travels to the flora. Both cross the botanical garden where the reference between the entry in the flora and the occurrence of the species in the wild is made explicit.

- The Effect of Noise-reducing Acoustic Panels on the Noise Levels and
Overall Safety of Infant Sleep Machines
Authors: Pranav Poola
Abstract: Infant sleep machines (ISMs) are devices used to help infants fall asleep faster and stay asleep for longer amounts of time, yet they can often be too loud for infantile ears, which could potentially be dangerous. This research aimed to minimize the risks of infant sleep machines without reducing the effectiveness of the infant sleep machines themselves through the use of acoustic panels. Based on previous studies, it was hypothesized that the acoustic panels would reduce the noise levels of the ISM to less than recommended limits of 50 dB-A. A specific corner of a designated room was prepared with a crib with a sound level meter placed inside and a table housing the ISM all to simulate a sleeping infant being exposed to the white noise from the ISM. After 30 trials were conducted without any soundproofing, another 30 trials were conducted after acoustic panels were placed on the walls behind the crib in order to reduce the noise levels of the ISM. Significant differences were found between the two groups, with the t-statistic of 30.9688 being much higher than the critical value of 1.697, and the p-value being less than 0.001, all with an alpha of 0.05. Finally, it was found that acoustic panels did reduce the noise levels to below less than 50 dB-A, which means the hypothesis was supported. This shows that acoustic panels have a significant effect on noise reduction for infants and are a safe, inexpensive option for parents.

- A Simple and Reliable Reporter Assay to Test siRNA-Mediated Silencing of
HIV-1 Gene Functions
Authors: Kylie R. Tager et al.
Abstract: The human immunodeficiency virus (HIV-1) infects and kills CD4+ T-lymphocytes causing a progressive loss of host immune competence, which ultimately leads to AIDS. RNA interference, as mediated by short interfering RNAs (siRNAs) designed to target viral mRNAs and expressed endogenously, offer a potential gene therapy approach to inhibit HIV replication. However, a simple and reliable method to screen the silencing activity of particular anti-HIV siRNAs is useful prior to conducting more extensive experimentation to determine the downstream effects on viral replication. Here, a short hairpin RNA (shRNA) targeting HIV-1 Rev (Revsh8526) was designed and cloned into an expression plasmid under the control of the RNA Polymerase III H1 promoter. To test the ability of Revsh8526 to silence Rev, a chimeric β-galactosidase reporter plasmid containing Rev exon 2 (β-galactosidase-RevE2) was generated. The ability of Revsh8526 to target and inhibit reporter gene expression was shown by X-gal staining and ortho-nitrophenyl-β-galactoside (ONPG) assay. The results of these assays indicated Revsh8526 effectively targeted and significantly inhibited β-galactosidase expression as compared to a non-targeted shRNA. These results show the utility of the chimeric β-galactosidase reporter in initial screening of siRNA reagents.

- Investigation of Staphylococcus aureus Bacteriophage Population at a South
Carolina University: The Disappearance of S. aureus Bacteriophage
Population Amidst the COVID-19 Pandemic
Authors: Korinne M. Swanson et al.
Abstract: Bacteriophages are naturally occurring, nonpathogenic viruses, which infect bacterial cells. Recently, bacteriophage research has increased with hopes of using them against antibiotic resistant bacterial infections in the future. This study aimed to determine a possible correlation between perceived stress and the Staphylococcus aureus bacteriophage population at Coastal Carolina University (CCU), Conway, South Carolina, using isolation and characterization techniques to further understand humans as a potential bacteriophage source. From October 2020 to March 2021, nasal and postauricular swab samples were collected from 12 participants on a monthly basis along with a perceived stress survey. Samples were subjected to filtration, amplification, plaque assays, and PCR techniques to identify and characterize bacteriophage. The purpose of this study was to understand humans as a repository for bacteriophage and to understand factors, namely perceived stress, which affect bacteriophage presence on humans. Results suggested that possible changes due to the COVID-19 pandemic, such as increased stress levels, mask wearing, and constant hand washing/ sanitizing, caused a drastic decrease in the Escherichia coli and Staphylococcus aureus phage population at Coastal Carolina University.
