Living a healthy and balanced life can be difficult for college students at Arizona State<br/>University due to the barrier of high cost of healthy food. To understand more about this problem<br/>we conducted research on the Tempe campus through surveys and virtual focus groups. We<br/>discovered that the cost of healthy food is one of the main barriers preventing students from<br/>eating healthy. We also learned that the students would be more willing to eat healthier if they<br/>could access healthy foods at a more reasonable price. Our solution to this problem was Eunoia,<br/>a service that allows students to receive discounts on healthy food and incentivize them to eat<br/>healthier in the future. Our company creates an innovative relationship between our customers,<br/>their private health insurance companies and local grocery stores throughout the Phoenix Metro<br/>area. Students at Arizona State University will be able to purchase healthy food items discounted<br/>by up to 30%. These discounts will be funded by their health insurance companies as well as the<br/>local grocery stores they purchase from. Our business model allows our customers to live<br/>healthier lives while also providing value to partnered health insurance companies and grocery<br/>stores. Once we established our business model, we spoke with students at Arizona State<br/>University and representatives from health insurance companies. Through these demographics,<br/>we received positive feedback and early traction with our idea. Our goal is to be able to<br/>implement our product in the Arizona State University community and then expand this product<br/>into a more general market to help all people live a pure and balanced life.
In this formative research project, we seek to better understand the general barriers to refugee access to higher education. Using mixed methods research--which included surveys, interviews, and course data--we evaluate the benefits and challenges experienced by refugee students in Israel who are enrolled in Arizona State University's Education for Humanity programs. In the end, this case study resulted in 24 recommend programmatic changes designed to eliminate the barriers that prevent refugee students from accessing and succeeding in higher education.
Serial femtosecond crystallography (SFX) with an X-ray free-electron laser (XFEL) has enabled the determination of protein structures and protein reaction intermediates in millisecond to microsecond time resolutions. Mix-and-Inject crystallography (MISC) at XFELs enables fast mixing in the magnitude of milliseconds in order to achieve desired reaction time points. For these experiments, numerical simulations of a hydrodynamic flow mixer capable of fast mixing by diffusion has been developed using both COMSOL Multiphysics 5.6 and QuickerSims Computational Fluid Dynamics (CFD) Toolbox for MATLAB. These simulation programs were compared by calculations of mixing times and concentration flow profiles. Mixing times in the range of 1-10 ms were calculated in COMSOL under certain flow rate conditions whereas mixing times in the range of 6-15 ms were calculated with QuickerSims. From these mixing times, reaction intermediates can be varied from sub-millisecond to several hundred millisecond time points for a MISC experiment. Explanations for the discrepancies between the two models were attributed to variations in parameter definitions and meshing. Further analysis on the mixing characteristics were investigated by calculating an analytical solution to the convection-diffusion equation for fluid flow in a two-dimensional rectangular channel. The concentration profile along the width of the channel for the analytical solution was compared with the numerical solution obtained with COMSOL and QuickerSims. Upon comparison, it was determined that the diffusion coefficient may not be a significant factor for the disagreement between the two hydrodynamic flow models.
British colonialism was a well-established facet of Western history. The British have been especially notable in colonizing countries within Africa as well as India. In terms of India, the ramifications of their actions have had a significant impact on the social and political structure from the 19th century to modernity. Many scholars have alleged that brutalities set forth by the British and the discriminatory practices enforced onto the Indian population were entirely new. However, while the violence incurred cannot be ignored, the actual governance and structural changes were heavily influenced by the Hindu caste system already established within India. The Hindu caste system is a centuries-old practice that designates followers into five, family-determined, class denominations from highest to lowest: Brahmins (priests), Kshatriyas (rulers and warriors), Vaishyas (merchants, landowners, skilled workers), Shudras (farmworkers, servants, and unskilled workers), and Dalits (out-casts). The given thesis focuses on the perceptions and interactions of the British in 19th century India as well as the structural changes enforced by the British. Numerous nineteenth-century texts such as Up the Country by Emily Eden and India in 1848 by Arthur Mills, M.P. Murray were centered on the environment and day-to-day changes of India in the form of travel/informational readings. Both texts are utilized in this argument to highlight how the caste system was a contributing factor in British administration, contrary to the general perception of scholars. More importantly, Up the Country, offers a glimpse of the realities within northern India, where the British had the strongest control and is utilized to draw parallels between the caste system and British actions during the 1800s. The effects of discrimination and inequality continue to have a considerable effect on the Indian population to this day. However, the British have hastily been given total blame for such ramifications without considering the role of Indian societal principles in these disparities.
Ants are widespread species of eusocial insects, and myrmecophily describes the species which are associated with ants. Many mites are myrmecophilous species and interact with hosts in many ways such as phoresis or parasitism. The relationship between ants and mites are interesting as parasitic species could be used to control the spread of invasive ant species. For this project, I reviewed the existing literature on myrmecophilous mites around the world and compiled a database of ant-mite associations, which I then used to characterize factors such as host specificity, attachment sites, and biogeographical patterns. This work demonstrates that existing research on myrmecophilous mites has been both geographically and taxonomically biased and highlights the need for much more comprehensive surveys of mites living in association with ants.
As much as SARS-CoV-2 has altered the way humans live since the beginning of 2020, this virus's deadly nature has required clinical testing to meet 2020's demands of higher throughput, higher accuracy and higher efficiency. Information technology has allowed institutions, like Arizona State University (ASU), to make strategic and operational changes to combat the SARS-CoV-2 pandemic. At ASU, information technology was one of the six facets identified in the ongoing review of the ASU Biodesign Clinical Testing Laboratory (ABCTL) among business, communications, management/training, law, and clinical analysis. The first chapter of this manuscript covers the background of clinical laboratory automation and details the automated laboratory workflow to perform ABCTL’s COVID-19 diagnostic testing. The second chapter discusses the usability and efficiency of key information technology systems of the ABCTL. The third chapter explains the role of quality control and data management within ABCTL’s use of information technology. The fourth chapter highlights the importance of data modeling and 10 best practices when responding to future public health emergencies.
Apolipoprotein (ApoE) plays an important role in the transport of lipids in the brain for normal functioning. There are three different isoforms of ApoE which are coded for by three alleles (E2, E3, E4). Patients carrying at least one copy of ApoE E4 are known to be at higher risk for developing Alzheimer’s disease (AD) and earlier onset of symptoms. This is due to the buildup of amyloid plaques and neurofibrillary tangles of the brain from the accumulation of tau proteins, which are associated with the progression of Alzheimer’s disease. However, findings on ApoE E2 have shown that it may be a protective allele since it is linked to a decreased risk of formation of amyloid plaques and neurofibrillary tangles. To study this phenomenon within the context of a local population group, polymerase chain reaction and gel electrophoresis were conducted on extracted DNA samples. The principal goal in this research study was to genotype ApoE variants using single nucleotide polymorphism (SNP) specific primers, and polymerase chain reaction to analyze the frequency in the Tempe population to determine future healthcare needs.
For immigrants around the world, the United States represents hope for a new life and new opportunities. Colleen Vesely, Bethany Letiecq, and Rachael Goodman, in their article “Parenting Across Two Worlds: Low-Income Latina Immigrants’ Adaptation to Motherhood in the United States” provide examples of how real-world Latinx immigrant mothers view their experience in the United States. Many of the stories they include tell idealized versions of the American dream, what all people hope for when they immigrate to America. The immigrants they interviewed commonly talk about how they want to create a better life for their children and how by creating a better life for them it made the entire struggle worth it. Vesely, Letiecq, and Goodman do not just focus on the positives of immigration, they also explore the different barriers they must overcome in order to even try and achieve the ideal immigration experience they dream of. Cristina Henríquez perfectly embodies both the hopes and struggles of immigrants in her novel The Book of Unknown Americans (2015) by using the viewpoints of multiple immigrants to tell their specific immigration stories. This project uses Vesely, Letiecq, and Goodman’s article about the challenges of Latinx immigrant mothers’ experiences in the United States as a basis for my argument. In this thesis I postulate that motherhood, as it others women, has a negative impact on the ability of these Latinx immigrant mothers to create a place for themselves and feel a sense of belonging as depicted in Cristina Henríquez’s The Book Unknown of Americans (2015).
