This study assessed the effects of running an eating prevention program on body image satisfaction/behavior and the leadership skills of collegiate women. The sample included a group of 43 undergraduate women who voluntarily chose to become peer-educators in the eating prevention program called the Body Project. Self-report questionnaires evaluating both the preoccupation with personal body image and general leadership skills were distributed and collected electronically. The results were analyzed to determine that being a peer leader in the Body project did not increase eating disorder symptoms but actually decreased the symptoms. It was also determined that being a peer educator had no effect on leadership skills. Therefore, being a peer leader is beneficial for reducing eating disorder symptoms, but not for advancing leadership skills.

Smartphone-based healthcare. It's becoming more real as technology advances, adding value to healthcare and opening the doors to more personalized medicine. The Medical Pal is a smartphone application that can track symptoms and analyze trends in the severity of those symptoms, alerting healthcare providers when there is a significant increase in the symptom severity. This is especially directed to the palliative patient, whose care is focused on managing symptoms and providing comfort. The HIPAA-compliant server used for the smartphone application was Catalyze.io and 40 Mayo Clinic Arizona palliative patients were surveyed on their smartphone usage to test the acceptance of this app in a clinical setting. A trial involving 9 simulated patients was conducted over a two week period to test the functionality of the app. A majority of surveyed patients (85%) expressed favor for the idea of a mobile ESAS, and the app was functioning, with the capability of displaying patient data on a healthcare provider's account. This project is intentionally a door-opener to an open field of opportunity for mobile health, symptom observation, and improvements in healthcare delivery.

The field of art conservation has evolved parallel to scientific advancements and in response to changing social conditions. Methods have expanded from dusting the surface of a work to bombarding an image with x-rays in an effort to fulfill the ultimate goal of restoration: to return a piece of art to the state originally created by the artist. The process has become much easier and more complex with the introduction of analytical equipment that shifted the focus of the field away from maintenance towards academic study. This work illustrates the changes the field and demonstrates the application of scientific techniques to specific works.

Description
The 23-step total synthesis of dolastatin 16, a cyclic depsipeptide of marine origin, is presented. Included are syntheses of nonnatural amino acids dolamethylleuine and dolaphenvaline. The biological activity of the synthetic product differed from naturally isolated dolastatin 16, which may indicate the initial screening identified an inactive compound and the active one was not detected initially, or may be a result of the conformational dynamics induced by the proline residues. Additionally, a family of structural analogues to the bacillistatins, another cyclic marine depsipeptide, were synthesized. These were deemed the silstatins. 8 modifications were produced. The alterations aimed to introduce a heteroatomic residue for further derivatization, such as producing an antibody-drug conjugate. This introduction did in general decrease the neoplastic activity of these agents, as expected, but by modulating the lipophilicity of the compound we were able to salvage much of the potency of the bacillistatins while potentially allowing prodrug development.

Description
As the prevalence of childhood obesity in the United States rises, opportunities for children to be physically active become more vital. One opportunity for physical activity involves children walking to and from school. However, children that live in areas with a pedestrian-unfriendly built environment and a low degree of walkability are less likely to be physically active and more likely to be overweight. The purpose of this study was to study walking routes from schools in low-income neighborhoods in Southwestern United States to a local community center. Walking routes from the three study schools (South Mountain High School, Percy Julian Middle School, and Rose Linda Elementary School) were determined by distance, popularity, and the presence of a major thoroughfare. Segments and intersections, which formed the routes, were randomly selected from each school's buffer region. The walking routes as a whole, along with the segments and intersections, were audited and scored using built environment assessments tools: MAPS, PEQI and Walkability Checklist. These scores were utilized to develop interactive mapping tools to visualize the quality of the routes, segments and intersections and identify areas for improvement. Results showed that the routes from Percy Julian to the Kroc Center were, overall, rated higher than routes from the other two schools. The highest scoring route, from the seven routes studied, was route 2 from Percy Julian to the Kroc Center along Broadway Road. South Mountain High School was overall the worst starting point for walking to the Kroc Center as those three walking routes were graded as the least walkable. Possible areas for improvement include installing traffic calming features along major thoroughfares and reducing the perceived risk to pedestrian safety by beautifying the community by planting greenery. Future directions include studying the built environment in South Phoenix communities that surround the Kroc Center.

Description
For my creative project, I originally decided to produce an original instrumental EP (Extended Play), its aim to bridge the gap between classical Choral/Orchestral literature and more modern Hip-Hop/Rhythm & Blues through the implementation of sample-based sounds and melodies. As the semester went on, however, I realized that my original focus was really putting a strain on my creativity. A broadening in scope was exactly what I needed to spark the creativity within me. I had to create what suited me at the time, or what was a reflection of my current environment. This change began to push me beyond what I believed I was capable of; the tracks for the EP seemed to follow effortlessly. For the first production on my EP, I sampled from an a cappella file that I found on a royalty-free music database. The file had a raw cut, sans instrumentation and effects, of a teenage girl singing an original Soul/Rhythm & Blues tune of hers named "Don't Go." Atop the vocal, I added an original drum kit and sub-bass waveform, sound-designed by me, and an airy synthesizer line. My second original production, titled "Dreams," is a production that exudes everything that I stand for and am inspired by with regards to music. This work is the kind of production that got me into producing music in the first place. It demonstrates simplicity and elegance in every sense. A Rhythm & Blues record (Monnie Riperton's Edge of a Dream), a simple, yet hard-hitting drum groove with drum sounds sampled from live drums, and bass-line were the only ingredients necessary to produce "Dreams." The video logs, an addition to the original productions, were put in place to track my progress throughout the semester. The observer gets to learn alongside me, from the inception and into the execution of the project, the facets of sampling, building a drum groove, and creating an arrangement. By including access to my workflow as part of this project, I wish to provide a dynamic, evolving tool for producers in the future.

Description
The Dorrance Center for Rare Childhood Disorders is a unique research division at TGen (The Translational Genomics Research Institute) that provides personalized care to children and young adults facing rare, undiagnosed diseases. TGen scientists believe that the answers to these enigmatic disorders can often be found in a person's genetic code. They aim to solve these genetic mysteries using whole exome sequencing, a method that prioritizes the protein-coding portion of the genome in the search for disease-causing variants. Unfortunately, a communication gap sometimes exists between the TGen scientists and the patients they serve. I have seen, first hand, the kind of confusion that this study elicits in the families of its participants. Therefore, for my thesis, I decided to create a booklet that is meant to provide some clarity as to what exactly The Dorrance Center for Rare Childhood Disorders does to help diagnose children with rare disorders. The purpose of the booklet is to dispel any confusion regarding the study by providing a general review of genetics and an application of these lessons to the relevant sequencing technology as well as a discussion of the causes and effects of genetic mutations that often times are linked to rare childhood disorders.

Description
Among wild rodent populations, vertical transmission is believed to constitute the primary route of infection for Lymphocytic Choriomeningitis Virus (LCMV), a non-lytic arenavirus with both acute and chronic forms. When carrier mice infected at birth with the acute Armstrong strain reproduce, they generate congenital carrier offspring containing a quasispecies of LCMV that includes Armstrong as well as its chronic Clone-13 variant. This study examined the genetic trends in the vertical transmission of LCMV from mothers infected perinatally with Clone-13. Viral isolates obtained from the serum of congenital carrier offspring were partially sequenced to reveal residue 260 in the glycoprotein-encoding region of their S segment, the site of a major amino acid change differentiating the chronic and acute strains. It was found that the phenylalanine-to-leucine mutation associated with Clone-13 was present in 100% of the isolates, strongly indicating that the offspring of Clone-13 carriers contain exclusively the chronic variant. This research has broad implications for the epidemiology of the virus, and, given the predominance of Armstrong in the wild, suggests that there must be a biological cost associated with Clone-13 infection in non-carriers.

Description
Physical activity as a health or nutrition related intervention might stimulate appetite and increase hunger due to increased energy expenditure. This study analyzed the effect of a postprandial 15-minute walk on the hunger and energy intake of 10 obese, pre-diabetic adults. Subjects participated in three 4-hour trials: a walk treatment (consume highly glycemic meal, walk for 15 minutes at a moderate pace, and rest for 4 hours), a fiber treatment (consume highly glycemic meal enriched with soluble fiber and rest for 4 hours), and a control treatment (consume highly glycemic meal without fiber and rest for 4 hours). The effects of each treatment on hunger and energy intake were measured using a Likert scale analysis (ranging from "completely satisfied" to "extremely hungry") at 4 hours post-treatment and pre/ post 24-hour dietary logs. The results showed no significant increase or decrease on hunger or energy intake for both the walk and the fiber treatment compared to the control treatment. This denies the idea that physical activity might increase short-term hunger, and supports the use of physical activity as a viable nutrition related intervention tool.

Description
Maternal health and mental health have recently become globally recognized as critical areas of focus. The continued research into the relationship between maternal health and mental health—in particular, how they are affected by public policy and infrastructure—is vital to the improvement of general health outcomes. An investigation of literature, current health landscape and indicators, gray literature, and the current policy landscape in an exemplar country (Australia), Bangladesh and Nepal was done. Bangladesh and Nepal were chosen due to the recent amounts of change seen in each country’s maternal health status. Both Bangladesh and Nepal are severely lacking in official mental health services, facilities, and personnel. The analysis revealed flaws and disparities in each country’s current policy landscape. Despite these disparities it should be recognized that policies and programs are being implemented – just in a very piecemeal manner, and not entirely by each country’s respective government. Integration of maternal health services and mental health services is recommended to improve functionality of already existing services. The addition of minimal but necessary components to health systems is recommended.
