Description
The human motion is defined as an amalgamation of several physical traits such as bipedal locomotion, posture and manual dexterity, and mental expectation. In addition to the “positive” body form defined by these traits, casting light on the body produces a “negative” of the body: its shadow. We often interchangeably use with silhouettes in the place of shadow to emphasize indifference to interior features. In a manner of speaking, the shadow is an alter ego that imitates the individual.
The principal value of shadow is its non-invasive behaviour of reflecting precisely the actions of the individual it is attached to. Nonetheless we can still think of the body’s shadow not as the body but its alter ego.
Based on this premise, my thesis creates an experiential system that extracts the data related to the contour of your human shape and gives it a texture and life of its own, so as to emulate your movements and postures, and to be your extension. In technical terms, my thesis extracts abstraction from a pre-indexed database that could be generated from an offline data set or in real time to complement these actions of a user in front of a low-cost optical motion capture device like the Microsoft Kinect. This notion could be the system’s interpretation of the action which creates modularized art through the abstraction’s ‘similarity’ to the live action.
Through my research, I have developed a stable system that tackles various connotations associated with shadows and the need to determine the ideal features that contribute to the relevance of the actions performed. The implication of Factor Oracle [3] pattern interpretation is tested with a feature bin of videos. The system also is flexible towards several methods of Nearest Neighbours searches and a machine learning module to derive the same output. The overall purpose is to establish this in real time and provide a constant feedback to the user. This can be expanded to handle larger dynamic data.
In addition to estimating human actions, my thesis best tries to test various Nearest Neighbour search methods in real time depending upon the data stream. This provides a basis to understand varying parameters that complement human activity recognition and feature matching in real time.

Description
Nearly seven decades ago, the US government established grants to the states for family planning and acknowledged the importance of enabling all women to plan and space their pregnancies, regardless of personal income. Since then, publicly-funded family planning services have empowered millions of women, men, and adolescents to achieve their childbearing goals. Despite the recognized importance of subsidized family planning, services remain funded in a piecemeal fashion. Since the 1940s there have been numerous federal funding sources for family planning, including the Title V Maternal and Child Health Services Program, Office of Economic Opportunity grants, Title XX Social Services Program, Title X Family Planning Program, Medicaid, and the State Children’s Health Insurance Program, alongside state and local support. Spending guidelines allow states varying degrees of flexibility regarding allocation, to best serve the local population. With nearly two billion dollars spent annually on subsidized family planning, criticism often arises surrounding effective local program spending and state politics influencing grant allocation. Political tension regarding the amount of control states should have in managing federal funding is exacerbated in the context of family planning, which has become increasingly controversial among social conservatives in the twenty-first century. This thesis examines how Arizona’s political, geographic, cultural, and ethnic landscape shaped the state management of federal family planning funding since the early twentieth century. Using an extensive literature review, archival research, and oral history interviews, this thesis demonstrates the unique way Arizona state agencies and nonprofits collaborated to maximize the use of federal family planning grants, effectively reaching the most residents possible. That partnership allowed Arizona providers to reduce geographic barriers to family planning in a rural, frontier state. The social and political history surrounding the use of federal family planning funds in Arizona demonstrates the important role states have in efficient, effective, and equitable state implementation of national resources in successfully reaching local populations. The contextualization of government funding of family planning provides insight into recent attempts to defund abortion providers like Planned Parenthood, cut the Title X Family Planning Program, and restructure Medicaid in the twenty-first century.

Description
This study examined upper extremity function, including manual dexterity, in chronic stroke survivors following a 10-week high intensity interval treadmill walking intervention. Six stroke survivors completed two 35-minute high intensity interval treadmill walking sessions based on ventilatory threshold per week. In addition, each participant completed one 30-minute low-intensity walking session at home. Participants completed upper extremity and manual dexterity testing at baseline, acutely, and after the 10-week intervention. Contrary to the prediction made, significant improvements in both paretic and non-paretic upper-extremity function including manual dexterity were not found. While time to complete the Nine Hole Peg Test (9HPB) somewhat decreased and the number of blocks transferred in the Box and Blocks Test (BBT) slightly increased, results were not found to be statistically significant. The results do suggest, nonetheless, that high intensity interval treadmill training may lead to improvements in upper extremity function and potentially daily living in chronic stroke survivors.

Description
Background: Physical inactivity is a major cause of obesity, hypertension, cardiovascular disease, and diabetes and has become a major public health problem. Physical inactivity is detrimental to one's health, but it has also created a significant healthcare burden. Within the past decade, many health-based interventions have been implemented to encourage physically inactive individuals to adopt a more active lifestyle. These health-based interventions have used social media websites, particularly Facebook, to establish social support between the participants of those interventions. There is currently limited research on this topic. This study aims to add to that literature by exploring strategies to encourage participants of health-based interventions to interact with a Facebook group. Purpose: An exercise and nutrition-based intervention called Athletes for Life (AFL) has been using a Facebook page over the past 2.5 years to establish social support between participants of the program, among other functions. The level of interaction that participants had with the Facebook page has declined over the past year. The objective of this study is to redesign and refine the AFL Facebook page so that it is more appealing and interactive to AFL participants. Methods: Redesigning and refining the AFL Facebook page were achieved through three strategies. The first strategy was to recruit approximately twenty participants to the new AFL Facebook group. The next strategy was to select a participant to become the group champion who would post encouraging content on the Facebook group wall. The final strategy was to maintain the consistency with which participants liked and viewed posts on the group wall. Results: The results of this study showed nine participants joined the group and these participants had a combined total of 62 likes and 110 views on the group wall over an eleven-week period. Participants interacted with the content posted by the Facebook group administrators on a consistent basis, but only one participant posted a recipe to the group wall. Measuring the level of interaction for each individual post was significant because it illustrated that the level of interaction participants had with posts depended on the identity of the posts' author. Conclusions: Future research should test the effectiveness of a Facebook group page for promoting physical activity and implementing the suggestions from study participants to increase Facebook usage.

Description
The Student Health Outreach for Wellness (SHOW) is a free, student-led interprofessional clinic and community outreach initiative that aims to serve individuals experiencing homelessness in Phoenix, AZ. Individuals experiencing homelessness face many situational and financial barriers to finding healthcare. In order to better understand these barriers, a community needs assessment (CNA) was conducted in Fall 2014 on the Human Services Campus (HSC), a hub of resources for the population. Results indicated chronic disease is moderately prevalent (37.21% and 27.91% reported obesity and hypertension, respectively, among others). Since chronic diseases can lead to more severe health issues, it is imperative to address, manage, and avoid these conditions. Health education programs are a key component of the SHOW clinic model and a means to address chronic disease. The Health Belief Model (HBM) is a theory-based behavior change model used in programs to increase patient adherence to and promotion of preventative health behaviors. SHOW health education programs will use the constructs of this model to inform program development. Since many student volunteers are not well-versed in health education literature, a SHOW Program Development Guide based on the HBM has been created. The guide will help ensure SHOW delivers high-quality and efficacious programs that have a long-lasting impact on patients now and as the organization continues to grow.

Description
Emergency departments (EDs) across the country have been forced to accommodate an ever-expanding population of mental health patients. This study surveyed physicians and social workers in order to determine the most commonly treated mental illnesses in the ED, common frustrations in the care of mental health patients, limitations in the provision of treatment, and possible changes and improvements to the treatment system for the future. Attitudes toward the deinstitutionalization movement of the 1960s also were assessed, as this movement is hypothesized to have contributed to the current strain on EDs with respect to treating mental health issues. In this thesis, the deinstirutionalization movement and possible implications for mental health treatment in EDs are reviewed' In addition, questionnaires were administered to a sample of 6 ED doctors and 2 ED social workers-. Survey responses suggest that more resources, including availability of ED staff psychiatrists and dedicated facilities for mental health patients' would offer improvements to the current system. With careful evaluation of the ability of the ED to meet the needs of mental health patients, alternative resources for more effective and successful treatment strategies may be developed that offer a compromise between institutionalization and the revolving door of the ED.

Description
The purpose of this study was to determine if there was a relationship between the constructs of motivational theories, Self-Determination Theory and Health Belief Model, and adherence to a home exercise program. The constructs of Self-Determination Theory are autonomy, competence, and social relatedness. The constructs of Health Belief Model are perceived benefits, perceived barriers, perceived severity, and perceived susceptibility. Participants were receiving therapy at two outpatient clinics located in the Phoenix metropolitan area (n=40). Autonomy was assessed with a modified Treatment Self-Regulation Questionnaire. Competence was assessed with a modified Perceived Competence Scale. Social relatedness was assessed with a modified Health Care Climate Questionnaire. Perceived benefits and barriers were measured with a modified Exercise Benefits/Barriers Scale. Perceived severity and susceptibility were measured with a modified Health Beliefs Questionnaire. Adherence was measured with one Likert-type question that was created by the researchers. The data was scored and analyzed with the scoring guidelines provided by the questionnaires and the statistics software, IBM Statistical Package for the Social Sciences. The results showed that competence was the only construct that was significantly correlated with home exercise program adherence. The results from this study should be used for further research that focuses on creating a competence-supportive environment in physical therapy settings.

Description
According to the Center for Disease Control, 1 in every 3 individuals will fall in their lifetime. Treadmill perturbation training has been a beneficial tool to increase reactive postural control and decrease the amount of falls. This study looked at the extent of the training effects on 29 healthy young adults to evaluate if stepping improvements in one direction could generalize to improvements in the quality of stepping in other directions. Outcome variables of Margin of Stability (MOS), step length, and step latency were evaluated for all 15 participants trained with forward perturbations and 14 participants trained with backward perturbations. From the paired t-tests, there were limited significant improvements in stepping with regards to motor learning and generalization. The only significant outcome was an increase in step length for the participants who trained in the backward direction (p=0.014; p<0.05). However, this significant increase in step length for this backward group did not generalize when the participants stepped in the forward direction post training. From the correlation tests, there was a significant, moderate correlation between motor learning and generalization (rho =0.527, p= 0.043; p<0.05), thus suggesting there may be a relationship between the amount of learning and the amount of generalization observed. Further evaluation of the second step and the foot motion during stepping may reveal more information and explain the changes in stepping to describe how healthy young adults were able to regain balance with each perturbation given.
