Artificial Biasedness: How Inherent Biases in the Creation of Algorithms make Artificial Intelligence Facial Recognition Programs Racially Biased
No full textabstract: Artificial Intelligence’s facial recognition programs are inherently racially biased. The programs are not necessarily created with the intent to disproportionately impact marginalized communities, but through their data mining process of learning, they can become biased as the data they use may train them to think in a biased manner. Biased data is difficult to spot as the programming field is homogeneous and this issue reflects underlying societal biases. Facial recognition programs do not identify minorities at the same rate as their Caucasian counterparts leading to false positives in identifications and an increase of run-ins with the law. AI does not have the ability to role-reverse judge as a human does and therefore its use should be limited until a more equitable program is developed and thoroughly tested. (abstract
The Effects of the PsaL Calcium Binding on the Oligomeric and Spectroscopic Properties in Synechocystis sp. PCC 6803
No full textabstract: In oxygenic photosynthesis, conversion of solar energy to chemical energy is catalyzed by the pigment-protein complexes Photosystem II (PSII) and Photosystem I (PSI) embedded within the thylakoid membrane of photoautotrophs. The function of these pigment-protein complexes are conserved between all photoautotrophs, however, the oligomeric structure, as well as the spectroscopic properties of the PSI complex, differ. In early evolving photoautotrophs, PSI exists in a trimeric organization, but in later evolving species this was lost and PSI exists solely as a monomer. While the reasons for a change in oligomerization are not fully understood, one of the 11 subunits within cyanobacterial PSI, PsaL, is thought to be involved in trimerization through the coordination of a calcium ion in an adjacent monomer. Recently published structures have demonstrated that PSI complexes are capable of trimerization without coordinating the calcium ion within PsaL. 5 Here we explore the role the calcium ion plays in both the oligomeric and spectroscopic properties in PSI isolated from Synechocystis sp. PCC 6803. (abstract
EVOLVE Academy: Keeping Children Engaged in Sports in a Digital Environment
No full textabstract: In 2020, the world was swept by a global pandemic. It disrupted the lives of millions; many lost their jobs, students were forced to leave schools, and children were left with little to do while quarantined at their houses. Although the media outlets covered very little of how children were being affected by COVID-19, it was obvious that their group was not immune to the issues the world was facing. Being stuck at home with little to do took a mental and physical toll on many kids. That is when EVOLVE Academy became an idea; our team wanted to create a fully online platform for children to help them practice and evolve their athletics skills, or simply spend part of their day performing a physical and health activity. Our team designed a solution that would benefit children, as well as parents that were struggling to find engaging activities for their kids while out of school. We quickly encountered issues that made it difficult for us to reach our target audience and make them believe and trust our platform. However, we persisted and tried to solve and answer the questions and problems that came along the way. Sadly, the same pandemic that opened the widow for EVOLVE Academy to exist, is now the reason people are walking away from it. Children want real interaction. They want to connect with other kids through more than just a screen. Although the priority of parents remains the safety and security of their kids, parents are also searching and opting for more “human� interactions, leaving EVOLVE Academy with little room to grow and succeed.

Exploring the Spatial Networks of Sustainable Agritourism in the Municipalities of Utuado, Ciales, Florida, and Jayuya, Puerto Rico
No full textabstract: As climate change continues to escalate natural hazards around the globe, certain communities feel the impacts of these disasters more so than others. After Hurricane Maria devastated communities in 2017, Puerto Rico struggled to respond to the needs of its citizens, particularly those in rural areas. Many of the regions affected did not have resilient community structures in place to be able to withstand the systemic ripple effects of the hurricane. However, various community endeavors have developed post-Hurricane Maria to foster community collaboration and resiliency, including the development of agricultural tourism, otherwise known as agritourism.
Although agritourism has begun to develop in rural regions of Puerto Rico, including the municipalities of Utuado, Ciales, Florida, and Jayuya, a systems-understanding is lacking of the current agritourism situation in the region and its related capacities, limitations, and opportunities of agritourism. To address this gap, a spatially explicit understanding and map of the underlying tourism infrastructure is needed to support the development of sustainable agritourism in Utuado, Jayuya, Ciales, and Florida municipalities in Puerto Rico.
This report spatially represents the current state of tourism opportunities in the region as a result of asking “What are the spatial networks of gastronomy, accommodations, farms, and attractions that support the development of agritourism in Utuado, Jayuya, Ciales and Florida municipalities in Puerto Rico?� Three steps lead to the spatial representation starting with developing a comprehensive inventory. Second, we visualize the spatial map through Google Maps. Lastly, we explore the larger context of the report through an ArcGIS Storymap. The inventory will help with better understanding the number and variety of tourism resources available. The spatial visualization will help with understanding the distribution of resources and explore potential connections between resources and what relationships could be fostered in the future. Lastly, the ArcGIS Storymap will serve as a framework for outlining the future development of the SARE project. Overall, this report outlines the spatial maps of tourism resources and provides a tool to be used by community partners, tourists, and project partners. (abstract
COVID-19 and College Students: The Relationships among Fear of COVID-19, Preventative Behaviors, & Vaccination Intention
No full textabstract: Objective: This study looked at three key variables of fear of COVID-19, preventative behaviors, and vaccination intent among college students in the United Sates. In addition, the three key variables were compared between genders, age groups, race groups, and over time to see if there were any significant findings.
Method: This longitudinal study consisted of two anonymous online surveys administered on REDCap before and after a COVID-19 vaccine became available.
Results: The findings suggested positive correlations between students’ fear of COVID-19 and their preventative behaviors with the passing of time. Hispanic/Latino participants had significantly higher fear of COVID-19 scores compared to Non-Hispanic Whites and other races at Wave I and II. Participants between 25 and 30 years old had a marginally greater difference fear of COVID-19 score compared to those less than 25. Females had significantly higher mean preventative behavior score than males at Wave II. There was a significant association between race/ethnicity groups and vaccination intent.
Conclusion: Knowing why different groups do not engage in recommended preventative behaviors or receive vaccinations can tell us more about what tailored interventions may need to be developed and implemented to promote health and wellbeing in this population. Further research needs to be done regarding race, gender, and age and how these different groups of college students are responding to COVID-19 and why. (abstract

A case for the Rehabilitation of Private Prisons within Arizona
No full textabstract: The privatization of prisons within Arizona has been a hot button issue and needs to be further analyzed to determine their benefits and expenses. To begin this investigation into the effectiveness of private prisons within Arizona and possible steps that need to be taken for its rehabilitation certain definitions and prior research need to be understood. Following this explanation, areas such as costs analysis across different types of prisons, liability rates across differing types of prison guards, and the differing psychology of different types of prisons can be examined to gain an overall assessment of the current performance of privatized prisons within Arizona. After this in-depth analysis of the current private prison system within Arizona, the flaws of the system will become abundantly clear and the solutions that should be implemented to alleviate these problems will be discussed.

The Future of Programming: The effectiveness and uses of digital content to engage students
No full textabstract: In a COVID-19 world, student engagement has suffered drastically as organizations and universities shifted to an online format. Yet, there is still an opportunity and a space for digital content creation to bridge the gap in a virtual and hybrid university lifestyle. This project looks at how student groups can still engage students at ASU Tempe through digital content creation and which tools to use to enter the space. (abstract
Contaminants in Philippine Fish (Siganus fuscescens) and Potential Effects on Public Health
No full textabstract: The Philippines relies on a vast biodiversity of fishes as a staple food, but like many countries around the globe, experiences severe “leakages� of contaminants and pollutants in the environment. In order to better understand the relationship between environmental pollutants and public health, this research project measured the concentration of pollutants in a commonly consumed local fish (Siganus fuscescens), and then evaluated the potential health risks of eating this fish based on estimated average consumer weight and consumption levels. Fish sampled from four different sites located in Negros Oriental, Philippines were analyzed for organic contaminants using gas chromatography and mass spectroscopy. Pollutants quantified included polycyclic aromatic hydrocarbons (PAHs), pesticides, phthalates, and polychlorinated biphenyl (PCBs). Across the four study sites, fishes from Manjuyod showed the highest frequency of detection of different pollutants. However, phthalates and PAHs were found in similar concentrations in all four sites, with fishes from Dumaguete showing the highest level of PCBs compared to the other sampled sites. The U.S. Environmental Protection Agency’s guide for fish contaminants pinpoints several health risks associated with the chronic ingestion of these contaminants. Based on estimated average body weights of Filipino adult men, adult women, and children, and various consumption levels, people who eat the fish at or above the national average consumption level may be at increased risk for chronic health outcomes, such as cancer and/or other adverse effects. Specifically, due to the high concentration of PCBs in Dumaguete, selected populations who eat local fish from this site may be at higher risk than the citizens who eat the fish from other sites at similar consumption rates. These results can help to inform local and national policies on water quality, waste disposal, and fish consumption advisory programs. (abstract
