The ringtail (Bassariscus astutus), a member of the Procyonidae, is capable of 180 degrees of hindlimb reversal during headfirst descent down a vertical substrate. The goal of this study was to determine the presence or absence of myological adaptations related to hindlimb reversal in the ringtail. Data for B. astutus are presented, including muscle weights and muscle maps ascertained from the dissection of four hindlimbs. Data from the current study were compared to published accounts of other species capable of hindlimb reversal, including procyonids (raccoon, coati, kinkajou, olingo), a mustelid (marten), palm civet, mongoose, tree squirrel, common tree shrew, and slow loris. Muscle mass data from this study demonstrate that the hip adductors of scansorial mammals are significantly more robust than those of terrestrial mammals, indicating a myological adaptation for climbing, but not necessarily hindlimb reversal. Among hindlimb reversers, the majority exhibit one belly of m. sartorius, the presence of m. extensor digiti I longus, and a fibular origin for m. fibularis longus. These characteristics indicate an emphasis on hip extension, ankle plantarflexion, and pes inversion. However, these characteristics are more likely due to phylogeny than hindlimb reversal because of their presence in closely-related non-reversers. Additional data on families outside of Carnivora may help determine if these myological traits are indeed due to phylogeny. Other myological data, such as moment arms and cross sectional areas, may provide evidence of adaptations for hindlimb reversal.

As society's energy crisis continues to become more imminent many industries and niches are seeking a new, sustainable and renewable source of electricity production. Similar to solar, wind and tidal energy, kinetic energy has the potential to generate electricity as an extremely renewable source of energy generation. While stationary bicycles can generate small amounts of electricity, the idea behind this project was to expand energy generation into the more common weight lifting side of exercising. The method for solving this problem was to find the average amount of power generated per user on a Smith machine and determine how much power was available from an accompanying energy generator. The generator consists of three phases: a copper coil and magnet generator, a full wave bridge rectifying circuit and a rheostat. These three phases working together formed a fully functioning controllable generator. The resulting issue with the kinetic energy generator was that the system was too inefficient to serve as a viable system for electricity generation. The electrical production of the generator only saved about 2 cents per year based on current Arizona electricity rates. In the end it was determined that the project was not a sustainable energy generation system and did not warrant further experimentation.

Dancers tend to injure the anterior cruciate ligament in their left leg more often than the right. It is unclear whether this trend is due to biased choreography or if leg dominance and left versus right asymmetries are contributing factors. The purpose of this study was to investigate asymmetries between the left and right leg, in knee abduction during landing, hip external rotation (ER) and internal rotation (IR) strength, and hip ER and IR range of motion in dancers compared to non-dancers. This study aimed to determine whether these asymmetries can be linked to leg dominance, and if this puts one leg at higher risk for ACL injury. Ten dancers and eleven non-dancers performed three maximal effort countermovement vertical jumps off of two feet, as well as three maximal effort single leg jumps on each leg. Knee abduction angles during the landing phase of the jumps were calculated using motion capture data. Maximum isometric hip ER and IR strength was measured at 15, 30, 45, 60, and 90 of knee flexion, and hip ER and IR range of motion was measured at 90 of knee flexion. Contrary to the hypothesis, few significant differences were found between the left and right leg, as well as between dancers and non-dancers. Dancers exhibited significantly greater IR range of motion than non-dancers, and knee abduction angles were greater on the right than left leg during double leg jumps. This opposes the hypothesis that knee abduction angles would be greater in dancers on the left leg. However, significant positive correlations were found
between IR strength and knee abduction angles during single leg jumps on the left leg, suggesting that IR strength may be a contributing factor to knee valgus. Further studies may want to utilize qualitative analyses, more relevant jumping tasks, and a different marker set to elucidate asymmetries of the lower limbs that may truly be present.

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.

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.

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.
