In this research we consider stochastic models of Glioblastoma Multiforme brain tumors. We first look at a model by K. Swanson et al., which describes the dynamics as random diffusion plus deterministic logistic growth. We introduce a stochastic component in the logistic growth in the form of a random growth rate defined by a Poisson process. We show that this stochastic logistic growth model leads to a more accurate evaluation of the tumor growth compared its deterministic counterpart. We also discuss future plans to incorporate individual patient geometry, extend the model to three dimensions and to incorporate effects of different treatments into our model, in collaboration with a local hospital.

It is well known that the lack of care coordination in the healthcare system causes numerous problems including cost inefficiency and inconsistent care, specifically for complex pediatric and adult patients. Many pediatric patients have complex medical and social service needs which can be expensive for both the patient’s parents and the general healthcare system. Therefore, it is difficult for the healthcare system to deliver the highest quality care possible, due to the number of appointments that have to be scheduled (with some being out of state), the large volume of physical health records, and overall lack of time parents have to coordinate this care while also caring for themselves and other family members. It is integral to find a more efficient way to coordinate care for these patients, in order to improve overall care, cost efficiency, and outcomes. <br/>A number of stakeholders in Arizona came together to work on this problem over several years. They were funded through a PCORI Eugene Washington Engagement grant to investigators at ASU. This project, Take Action for Arizona's Children through Care Coordination: A Bridge to Action was developed in order to further develop a research agenda and build the network (PCOR). Regional conferences were conducted in Flagstaff, Yuma, Phoenix, and Tucson, as well as a final capstone conference held in Phoenix. At these conferences, frustrations, suggestions, and opinions regarding Children with Special Health Care Needs (CSHCN) and navigating the healthcare system were shared and testimonials were transcribed.<br/>This study focused on the capstone conference. The study design was a strategic design workshop; results of the design analysis were analyzed qualitatively using descriptive content analysis. Themes described parent’s common experiences navigating the system, impacts resulting from such experiences, and desires for the care coordination system. Quotes were then grouped into major themes and subthemes for the capstone conference. After these themes were determined, the overarching goals of stakeholders could be assessed, and implementation projects could be described.

The United States’ War on Drugs declared in 1971 by President Richard Nixon and revamped by President Reagan in the 1980s has been an objectively failed initiative with origins based in racism and oppression. After exploring the repercussions of this endeavor for societies and individuals around the world, global researchers and policymakers have declared that the policies and institutions created to fight the battle have left devastation in their wake. Despite high economic and social costs, missed opportunities in public health and criminal justice sectors, and increasing limits on our personal freedoms, all the measures taken to eradicate drug abuse and trafficking have been unsuccessful. Not only that, but militarized police tactics, mass incarceration, and harsh penalties that stifle opportunities for rehabilitation, growth, and change disproportionately harm poor and minority communities. <br/>Because reform in U.S. drug policy is badly needed, the goals of America’s longest war need to be reevaluated, implications of the initiative reexamined, and alternative strategies reconsidered. Solutions must be propagated from a diverse spectrum of contributors and holistic understanding through scientific research, empirical evidence, innovation, public health, social wellbeing, and measurable outcomes. But before we can know where we should be headed, we need to appreciate how we got to where we are. This preliminary expository investigation will explore and outline the history of drug use and prohibition in the United States before the War on Drugs was officially declared. Through an examination of the different patterns of substance use, evolving civil tolerance of users, racially-charged anti-drug misinformation/propaganda campaigns, and increasingly restrictive drug control policies, a foundation for developing solutions and strengths-based strategies for drug reform will emerge.

This thesis discusses why there is so much employee turnover in the Sports Programs department, which is a working department of the Sun Devil Fitness Complex on Arizona State’s Tempe Campus. The analysis discusses the problems that have been noticed from personal experience, and the problems that have been explained by employees that left about why they decided to leave. The analysis is done based on the concepts of the four frames, based on research documented by Bolman and Deal in their book. There is an overview of all of the departments and specifically the Sports Programs department, and a deep dive into what that department does. There is a discussion of what problems may be present, and some solutions such as debriefings, trainings, and more objective evaluations that can be implemented into the department to try to fix the problems that have been noticed.

I conducted a literature review of articles pertaining to the history and treatment of rats. After outlining all of the relevant connections, I argue that as a result of people's conceptions about rats, rats do not receive the same respect and protections afforded other animals, such as cats and dogs, in the laboratory and beyond. I present both negative and positive conceptions about rats and the realities of these conceptions. Finally, I talk about the changes that need to take place in laboratory research, why animals are still used in research today, and the alternatives that exist to animal models.

This project explorers the potential reasons for the discrepancies between state responses to the COVID-19 pandemic, with a particular focus on the possibility of a correlation between political ideology and a state’s nonpharmacological intervention policy timing. In addition to outlining the current literature on the preferences of conservative and liberal ideology, examples of both past and present scientific based pandemic responses are described as well. Given the current understanding of the social and economic dimension of conservative and liberal political ideology, it was hypothesized that there may be a positive correlation between conservative ideology and premature action by a state. Data was collected on the current ideological landscape and the daily COVID-19 cases numbers of each state in addition to tracking each state’s policy changes. Two correlation tests were performed to find that there was no significant positive or negative correlation between the two variables.

Vocal emotion production is important for social interactions in daily life. Previous studies found that pre-lingually deafened cochlear implant (CI) children without residual acoustic hearing had significant deficits in producing pitch cues for vocal emotions as compared to post-lingually deafened CI adults, normal-hearing (NH) children, and NH adults. In light of the importance of residual acoustic hearing for the development of vocal emotion production, this study tested whether pre-lingually deafened CI children with residual acoustic hearing may produce similar pitch cues for vocal emotions as the other participant groups. Sixteen pre-lingually deafened CI children with residual acoustic hearing, nine post-lingually deafened CI adults with residual acoustic hearing, twelve NH children, and eleven NH adults were asked to produce ten semantically neutral sentences in happy or sad emotion. The results showed that there was no significant group effect for the ratio of mean fundamental frequency (F0) and the ratio of F0 standard deviation between emotions. Instead, CI children showed significantly greater intensity difference between emotions than CI adults, NH children, and NH adults. In CI children, aided pure-tone average hearing threshold of acoustic ear was correlated with the ratio of mean F0 and the ratio of duration between emotions. These results suggest that residual acoustic hearing with low-frequency pitch cues may facilitate the development of vocal emotion production in pre-lingually deafened CI children.

Obesity rates among adults have steadily grown in recent decades all the way up to 42.4% in 2018. This is a 12% increase from the turn of the century (Center for Disease Control and Prevention, 2021). A major reason for this rise is increased consumption of processed, high-calorie foods. People eat these foods at a young age and develop bad eating habits that can last for the rest of their lives. It is essential to intervene early and help adolescents form balanced, healthy eating habits before bad habits are already formed. Our solution to this problem is Green Gamers. Green Gamers combines adolescent’s passion for gaming with healthy eating via in-game rewards for healthy eating. People will be able to purchase healthy food items, such as a bag of carrots, and on the packaging there will be a QR code. They will then be able to scan the code on our website, and earn points which will unlock in-game items and other rewards. Video game rewards act as effective motivators for you people to eat more healthy foods. After the solution was formulated, a preliminary survey was conducted to confirm that video game related rewards would inspire children to eat more healthy foods. Based on those results, we are currently in the process of running a secondary market research campaign to learn if gift card rewards are a stronger motivator. Our end goal for Green Gamers would be to partner with large gaming studios and food producers. This would allow us access to many gaming franchises, so that rewards are available from a wide variety of games: making the platform appealing to a diverse audience of gamers. Similarly, a relationship with large food producers would give us the ability to place QR codes on a greater assortment of healthy food items. Although no relationships with large companies have been forged yet, we plan to utilize funding to test our concept on small focus groups in schools.

Patent protection creates an encouraging environment for innovation, but it can be a hindrance to the availability of new medications. There are many countries that still harbor this competition while ensuring that all citizens have access to these medications. There are downsides to certain patent systems, but with a few modifications they can be remedied to achieve the highest level of access, quality of care, and best cost for the insured. In most of the countries reviewed, the patent system is thoroughly regulated with the consumers in mind. There are opportunities for manufacturers to create generic and cost effective medications within the typical patent protection timeline to ensure access to new medications. The systems that are in place encourage innovation with medical devices and medication by providing incentives for the researchers.

Antibiotic resistance is a growing crisis across the globe. With the use of antibiotics in heathcare settings in an ever-growing population, the growth of antibiotic resistance has been named a top 10 global public health threat by the World Health Organization. Through an analysis of 6 countries; Mexico, China, the United States, India, Saudi Arabia, and Ethiopia, I look at the current implementation of policy and contributing factors to the use and abuse of antibiotics within the country. Through my research, I was able to find knowledge, behaviors, and a lack of enforcement to be the main contributors to the growing antibiotic crisis. Based on the evidence, I suggested three policies that focused on treatment, prevention, or economic assistance in an effort to combat the antibiotic crisis on a global scale. With socio-economic factors in mind as well as sustainability of policy, the evidence pointed in the direction of a three-pronged approach on prevention with education, policy enforcement, and a global database to minimize the growth of antibiotic resistance as well as improve public health at a global level.
