A point of care glucose sensor using electrochemical impedance spectroscopy (EIS) with a glutaraldehyde-linked enzyme shows promise as an effective biosensor platform. This report details the characterization of various factors on optimal binding frequency (OBF) and sensor performance to better prepare the sensor for future experimentation. Utilizing a screen printed carbon electrode, the necessary amount of glucose oxidase was determined to be 10 mg/mL. Binding time trials ranging from 1-3 minutes demonstrated that 1.5 minutes was the optimal binding time. This timeframe produced the strongest impedance response at each glucose concentration. Using this enzyme concentration and binding time, the native OBF of the biosensor was found to be 1.18 Hz using vector analysis. Temperature testing showed little change in OBF in sensors exposed to 4 \u00B0C through 43.3 \u00B0C. Only exposure to 60 \u00B0C resulted in rapid OBF change which was likely due to glucose oxidase becoming denatured. Humidity tests showed little change in OBF and sensor performance between sensors prepared at the humidities of 7.5%, 10.625% and 16.5% humidity. Alternatively, solutions containing common interference molecules such as uric acid, acetaminophen, and ascorbic acid resulted in a highly shifted OBF and drastically reduced signal.

Brundtland’s definition of sustainability is the ability to “meet the needs of the present without compromising the ability of future generations to meet their needs” (IISD, 2021). But what if there are no future generations? Social sustainability, the sector of sustainability that foregrounds the well-being and livelihoods of people (and thereby continuation of humanity), is included in definitions within the sustainability field, but less developed in sustainability practice. In an effort to bridge this gap of knowledge, 14 U.S. cities and over 100 sustainability policies were analyzed for their social sustainability performance. An eight-item analytical framework that deals with differing areas of social equity guided the analysis. Results found that most cities’ sustainability departments fell short of truly addressing social sustainability concerns. Out of the eight items, the most frequently addressed were housing security and racial and gender equality whereas few, if any, cities addressed the more specific social concerns of immigration, technology and media, or arts/cultural preservation. Future research is recommended to gain a better understanding of the ways existing cities can improve in this area.

2D fetal echocardiography (ECHO) can be used for monitoring heart development in utero. This study’s purpose is to empirically model normal fetal heart growth and function changes during development by ECHO and compare these to fetuses diagnosed with and without cardiomyopathy with diabetic mothers. There are existing mathematical models describing fetal heart development but they warrant revalidation and adjustment. 377 normal fetuses with healthy mothers, 98 normal fetuses with diabetic mothers, and 37 fetuses with cardiomyopathy and diabetic mothers had their cardiac structural dimensions, cardiothoracic ratio, valve flow velocities, and heart rates measured by fetal ECHO in a retrospective chart review. Cardiac features were fitted to linear functions, with respect to gestational age, femur length, head circumference, and biparietal diameter and z-scores were created to model normal fetal growth for all parameters. These z-scores were used to assess what metrics had no difference in means between the normal fetuses of both healthy and diabetic mothers but differed from those diagnosed with cardiomyopathy. It was found that functional metrics like mitral and tricuspid E wave and pulmonary velocity could be important predictors for cardiomyopathy when fitted by gestational age, femur length, head circumference, and biparietal diameter. Additionally, aortic and tricuspid annulus diameters when fitted to estimated gestational age showed potential to be predictors for fetal cardiomyopathy. While the metrics overlapped over their full range, combining them together may have the potential for predicting cardiomyopathy in utero. Future directions of this study will explore creating a classifier model that can predict cardiomyopathy using the metrics assessed in this study.

This paper conducts an exploration of the election policy reaction to the COVID-19 pandemic within the United States. While living through and voting during the real-time events which took place during the COVID-19 Pandemic of 2020, it soon became evident that there was not enough experience from earlier election emergencies to properly ensure against voter disenfranchisement. Given the scope of the global pandemic and the speed with which policymakers had to act, there was very little time to properly prepare. There was also great contention regarding the legitimacy of election methods proposed to alleviate in-person election concerns, such as mail-in voting. The political battle between those who believed COVID-19 to be a grave concern against those who did not consider COVID-19 to be a legitimate threat towards their livelihoods also affected policymaking decisions. Policymakers were forced into a corner, as they experienced criticism for not enough government action, as well as disapproval on the actual regulation that came to pass. This paper therefore aims to understand what factors led to the decisions which shaped the election policy which occurred as a reaction to the COVID-19 pandemic during the election year of 2020. This analysis is conducted by considering the following: prior election emergency policy; the development of reactive election policy in March, proactive policy established for the August and November elections; and a review of voter disenfranchisement which occurred due to COVID-19.

The purpose of this cookbook and ingredient index is to simplify the reasoning behind eating a plant based diet--including how it can be beneficial to your health, and what benefits each ingredient provides. These recipes have been cultivated and modified over time to provide nutritious meals that are also tasty. I was introduced to healthy eating at a young age, and have been fascinated by it ever since. The recipes and information conveyed about a plant based diet have come from the many books read and research I have done on the subject. This paper will walk you through how I started this journey, and go on to show a basic overview of what makes up the foods we consume and why we need them. The cookbook portion of my Thesis contains recipes for breakfast, lunch, dinner, snacks, sauces, and dessert. Following the cookbook is an ingredient index that goes through the majority of ingredients used in my recipes, and what health benefits they provide. I hope that by reading this, others will be inspired to use more plant-based whole foods in their diet, and realize the healing that can come from them.

Habitual Health is a holistic health firm meant to provide the Arizona State University students with awareness of healthy practices. Our Founders Ava Bobbs, Mario DiVenere, and Jack Hammond have found that students have a severe lack of knowledge involving healthy practices including diet, fitness, and cooking. The combination of our strengths and complements to weaknesses puts the firm in a strong position to garner market share and provide value to our company. Throughout on-campus research, the team found that the average Arizona State University student does not feel that they have the sufficient means to be healthy, which is a huge misalignment that prevents the average ASU student from living a healthy lifestyle. This is where Habitual Health comes in, we are going to bridge the gap between the lack of information about healthy initiatives and the implication that living a healthy lifestyle is too expensive, difficult, and time consuming. Habitual Health is a paid platform where ASU students can go to access fitness plans, recipes, topical discussions and analysis, and other health related resources. The product we have established is an interactive, user-friendly website that includes various healthy recipes, nutritional tips and habits, and physical exercise routines. Our data is based on running the website from 01/20/2023 - 03/01/2023. Our company's value proposition is that students’ health would benefit long-term from our platform's resources. We have targeted the ASU Greek Community, which includes roughly 6% of the ASU population.1 We tested our product within the Greek community because of the tight knit nature of the community, as well as the communal kitchen system in the Greek Leadership Village making it harder for those individuals to cook for themselves. We expect to see a revamped community within the GLV, causing a positive impact across the entire campus.

This thesis investigates the policy surrounding English Language Learners (ELL) on both a federal and state level, with an emphasis on the state of Arizona. Arizona ELL policy and pedagogy have been the subjects of research nationwide; many studies demonstrate that ELLs struggle before, during and after participating in Arizona ELL programs (Lillie et al. 2012; Roa 2012; Office of Civil Rights 2012). Despite this previous research there were limited comprehensive overviews of the data that had been collected as well as recommendations that could be created utilizing the data. This thesis addresses that void of information through 1) A comprehensive literature review of the framework of policies used on the federal and state level, and 2) recommendations provided that are based on the findings of the literature included in the review. Study findings present that there is limited literature to support the English-Only policies currently enforced in the state of Arizona and that students would be better served to utilize other language acquisition approaches that view their primary language as a resource rather than a problem. Additionally, the literature suggests that there needs to be greater oversight in what language is being used to define certain groups so that all students receive proper resources and that there needs to be more communication about federal and state guidelines currently in place. It was recommended that extended research be conducted given recent policy shifts in the state of Arizona that occurred while the thesis was written, that future policy should account for greater inclusivity as well as continuous support, and that the state of Arizona reframe most of its current policies to be more fully aligned with research-based strategies.
