Description
Brought on by extended survival due to Highly Active Anti-Retroviral Therapy and increased incidence among older adults, the demographic profile of the HIV epidemic has begun to shift towards the aging population. As people living with HIV (PLWH) begin to age and develop multiple comorbidities, their needs are no longer limited to HIV treatment and disease management; they may require aging services similar to those with a negative HIV status. Increased attention has been placed on HIV and aging to assess the unique needs of older PLWH, however, limited research exists on the preparedness of aging services to provide adequate care to this population. This study aims to assess HIV and aging within Maricopa County, where individuals aged 50 years and older account for nearly half the reported HIV/AIDS cases in the county, and 30% of cases in Arizona. Two focus groups – one with older PLWH and another with aging service professionals – were conducted to gather information about existing aging services and the perspectives of older PLWH regarding their growing needs. Older PLWH were found to experience challenges similar to those that have been well-documented in previous studies: most notably, PTSD and other mental health conditions; fear of the future and isolation; HIV status disclosure and stigma; and economics and financial security. An anonymous survey was developed in conjunction with Aunt Rita’s Foundation to evaluate Maricopa County aging services; it was discovered that providers lack experience with HIV and admit deficiencies in their preparation to address the age-related concerns of older PLWH. The results show that the majority of providers were supportive of offering care to older PLWH and expressed interest in improving their preparedness. Future research is necessary to obtain perspectives from additional aging services in Maricopa County and word towards the development of an aging services directory to connect older PLWH to care.

Description
This research project investigated known and novel differential genetic variants and their associated molecular pathways involved in Type II diabetes mellitus for the purpose of improving diagnosis and treatment methods. The goal of this investigation was to 1) identify the genetic variants and SNPs in Type II diabetes to develop a gene regulatory pathway, and 2) utilize this pathway to determine suitable drug therapeutics for prevention and treatment. Using a Gene Set Enrichment Analysis (GSEA), a set of 1000 gene identifiers from a Mayo Clinic database was analyzed to determine the most significant genetic variants related to insulin signaling pathways involved in Type II Diabetes. The following genes were identified: NRAS, KRAS, PIK3CA, PDE3B, TSC1, AKT3, SOS1, NEU1, PRKAA2, AMPK, and ACC. In an extensive literature review and cross-analysis with Kegg and Reactome pathway databases, novel SNPs located on these gene variants were identified and used to determine suitable drug therapeutics for treatment. Overall, understanding how genetic mutations affect target gene function related to Type II Diabetes disease pathology is crucial to the development of effective diagnosis and treatment. This project provides new insight into the molecular basis of the Type II Diabetes, serving to help untangle the regulatory complexity of the disease and aid in the advancement of diagnosis and treatment.

This thesis discusses the complex situation involved in a person’s choice or means to vaccinate
themselves as well as their children. Included is a brief history on vaccines, a section describing
their mechanism of action, as well as information on how the vaccines work within our bodies.
The focus will then turn to the patient’s choice on whether or not to vaccinate themselves or their
child, including factors such as socioeconomic status, education level and their location. Within
this paper are the views of anti-vaccinators, as well as the views of pro-vaccinators and
suggestions on how to reeducate the public. I conclude that the AFIX model is of particular value
in public education: This involves Assessment of immunization coverage, Feedback in
informing providers of their performance, Incentives to help keep them motivated, and eXchange
of information which can be combined with incentives. While the AFIX model has focused on
doctors and nurses in the past, I conclude this model would be most effectively employed with
pharmacists, who see patients more routinely and often have higher levels of trust among the
general public.

Description
REACT is a student-led venture which strives to address the healthcare disparities from geographic, linguistic and cultural isolation of the refugee community in Arizona/Phoenix. We will achieve this by Understanding the needs of the community, Engaging the community directly, Educating through the use of culturally appropriate materials, and providing access to supplemental Patient Care.
This venture is unique in that it is an interdisciplinary fusion between students, health professionals, and non-profit organizations empowering underserved refugees. A refugee is an individual forced to leave their country because of persecution, war, or violence. Once they arrive in the United States, they are forced to restart their lives, often with little to no financial assets, minimal English literacy, and a lack of transferable skills from their previous occupations in their home countries. In addition to these socioeconomic disparities, it is common for refugees to face health disparities. Consequently, refugees are one of the most vulnerable populations in our society.
Our organization provides value to the refugee community through our three key services. These are made up of supplemental resources, educational workshops, and clinical services. Our supplemental materials include resources that our clients will use after they have left our care to further improve their health and quality of life. These items include personal hygiene kits, informational pamphlets, and nutritional foods.
The educational workshops we provide specifically address identified knowledge gaps that impede the autonomy of our clients’ health and wellbeing. Several of the topics that we cover (but are not limited to) are diabetes, postpartum depression, nutrition, dental hygiene, AHCCCS, and nutrition. The clinical services that the clinic will provide will be supplementary primary care services that will encompass basic physical exams, A1C blood pressure checks, and vaccinations. These services all are aimed at alleviating the barriers to health that refugees face and ultimately improve their quality of life.
Our venture seeks to maintain positive and sustained relationships with our client segments through continuous community engagement. In conjunction with providing educational workshops and clinical care in the future, REACT continually engages the community by planning formal and informal programming with the refugees based on the needs and wishes of individual communities.
REACT generates these services through the work of medical students from Mayo Clinic Alix School of Medicine and undergraduates from Arizona State University. Our team brings together the experience from hundreds of hours of work in the community, collaborations with refugee community leaders, and the insight of professionals in the healthcare/social-work industry.
Further, our members have had extensive experience working with refugees, training in culturally sensitive practices, and delivering care to those that need it most. With the cost of healthcare exponentially rising, there is little hope for refugees to find adequate culturally competent healthcare. This leads to an increase in chronic diseases, preventable health issues, and increased hospitalization costs. Supporting REACT is not only an investment in the health of the refugees but the health of our entire healthcare system.

Whistleblowing in Biomedical Research and Medicine: An Analysis of Ethical Expectations and Dilemmas
Description
In biomedical research institutions and medical institutions alike, whistleblowing, or the reporting of misconduct, has been severely retaliated against. Whistleblowers report misconduct by adhering to institutional whistleblowing policies, and do so in order to maintain ethical practice within their institution; it is important to note that by taking this ethical action, whistleblowers are aiming to protect the future of biomedical research and medicine. Despite these intentions, whistleblowing has developed a negative stigma due to the misconception that whistleblowers have self-proclaimed authority and are unable to function as part of a team. The retaliation against whistleblowers has been connected to psychological and professional fallout for the whistleblower, and it has been found that many whistleblowers suffer as a direct result of a lack of institutional support. The problems with whistleblowing culture demonstrate issues surrounding how ethics are maintained in institutions, who ethics policies apply to, and who has authority. The retaliation seen against whistleblowers outlines inherent institutional failures, and highlights the need for institutional change in order to both promote ethical practice and protect the whistleblowers who adhere to ethics policies. This thesis discusses such failures in detail, and outlines several broad solutions in order to combat this issue.

Description
In our exponentially expanding world, the knowledge of a group versus that of an individual is more relevant than ever. Social insects have evolved to rely on the information from the collective, and in the case of harvester ants, their choice revolves around the best seeds to collect.
The objective of this experiment is to study a colony’s seed preference following previous exposure to a seed type in the seed harvester ant Pogonomyrmex californicus. It was hypothesized that foragers would demonstrate a measurable preference for the seed type they had previously experienced over the novel seed type. The cuticular hydrocarbon profile is suspected to be an influence in the foragers’ seed selection. Following an incubation period with the designated seed type, a series of preference trials were conducted over the course of two days for two experiments in which each colony fragment was given a seed pile with a 1:1 ratio of niger and sesame, after which any seeds moved off the seed pile were determined to be chosen, as well as if the workers were observed moving the seeds off the pile from the video recordings. Using video recordings, the seed selections of individual foragers were also tracked. The results partially support the hypothesis, however, in some cases, the ants did not collect enough seeds for the preference to be significant, and not all colony fragments had preferences that lined up with what they had previously experienced according to their treatment. Familiarity with the hydrocarbon profile of the seed type the colony had experienced is a possible proximal explanation for why colonies had seed preferences that aligned with their treatment, the seed they were designated to experience. Due to the low quantity of seeds collected during preference trials, seed preference amongst individual foragers remains unclear due to many different foragers selecting a seed during only one trial, with very few foragers returning to forage for seeds over the course of the experiment.

Description
Many young people from The Gambia have been migrating illegally by routes through the desert to get to Libya and across the Mediterranean Sea to get to Italy. This is called back-way migration. A fair number of articles have been written that focus on the migrants leaving; however, the story that is not being told as often is about the families they leave behind. This thesis seeks to explore the everyday problems that occur to the families left behind and the country at large, as a result of the mass exodus of young people.

Description
The number of cancer survivors in the United States is growing rapidly and it is expected to double by 2040. Arizona is nationally ranked with the 14th highest number of survivors, many of which experience a wide range of persisting medical complications that result from the cancer and associated treatment. Consequently, there is an increased need for services tailored to the health and wellness of survivors. Studies have shown that exercise rehabilitation is effective in improving the physical and mental health of this patient population. This project aimed to investigate the status of medically-based exercise rehabilitation for cancer survivors in Arizona. It focused on services offered by cancer treatment centers and cardiac rehabilitation clinics, with cardiac rehabilitation providing a possible delivery method for future cancer exercise rehabilitation. A directory of resources was compiled based on responses to structured telephone interviews with the cancer treatment centers (n=32) and cardiac rehabilitation clinics (n=34) within the state. The directory will serve as a resource for both patients and clinicians by identifying statewide related services that are available at the medical institutions and within the community. Results showed that 42.9% and 39.4% of the cancer treatment centers and cardiac rehabilitation clinics, respectively, offered exercise related services for cancer survivors. 78.6% of cancer centers stated that they refer cancer survivors to physical therapy, while only 35.7% refer survivors to community-based programs. Only 2 cardiac rehabilitation clinics, or 6%, offered preventative cardiology exercise consultations to cancer survivors. In conclusion, rehabilitative exercise resources for cancer survivors in Arizona were limited. Additional cancer rehabilitation efficacy studies are needed to further clarify evidence-based practice guidelines and provide direction for optimal methods of healthcare delivery. It is recommended that this directory remains current with routine updates in an effort to increase patient accessibility to care.

Description
In my path through both the academic and the professional music world, I have realized that violinists traditionally operate in a very limited role when it comes to pop music. Rarely are string players integral to a song, and rarely are they allowed to indulge in creativity or improvisation. This three-track EP explores the various roles and functions that both the violin and the 21st-century violinist can have, beyond the stereotypical string pads in ballads and non-rhythmic, chordal accompaniment. The first track explores the violin providing chordal and rhythmic foundation of a song, containing only vocals and a midi bass as non-violin elements. The second track investigates the importance of production skills and strings providing the melody for a groove based up-tempo electronic drop. The final track is a more traditional yet accessible composition for piano and string quartet, inspired by the work of Ólafur Arnalds and Max Richter, potentially viable for modern dance choreography. The process of writing, recording, and producing this EP served as my first legitimate foray into the professional songwriting world. It is a testament to my battle with, and a temporary victory over, toxic perfectionism. This is an affliction that befalls creators of all trades: the crippling fear of putting out something less than perfect resulting in nothing being put out at all. Finally, I have put something out, something I am solely responsible for, that represent my original creative work. This EP seeks to set a blueprint for the capabilities of modern string playing and modern string players often neglected in the modern popular music sphere. It is the culmination of all I have learned as a musician, technically, professionally, and emotionally.
