Description
The biohacker movement is an important and modern form of activism. This study broadly examines how positive-activist-oriented biohackers emerge, organize, and respond to social crises. Despite growing public awareness, few studies have examined biohacking's influence on prevailing notions of organizing and medicine in-context. Therefore, this study examines biohacking in the context of the 2016 EpiPen price-gouging crisis, and explores how biohackers communicatively attempted to constitute counter-narratives and counter-logics about medical access and price through do-it-yourself (DIY) medical device alternatives. Discourse tracing and critical case study analysis are useful methodological frameworks for mapping the historical discursive and material logics that led to the EpiPen pricing crisis, including the medicalization of allergy, the advancement of drug-device combination technologies, and role of public health policy, and pharmaceutical marketing tactics. Findings suggest two new interpretations for how non-traditional forms of organizing facilitate new modes of resistance in times of institutional crisis. First, the study considers the concept of "pop-up maktivism" to conceptualize activism as a type of connective activity rather than collective organizing. Second, findings illustrate how activities such as participation and co-production can function as meaningful forms of institutional resistance within dominant discourses. This study proposes “mirrored materiality” to describe how biohackers deploy certain dominant logics to contest others. Lastly, implications for contributions to the conceptual frameworks of biopower, sociomateriality, and alternative organizing are discussed.

Description
This dissertation explores the impact of environmental dependent risk on disease dynamics within a Lagrangian modeling perspective; where the identity (defined by place of residency) of individuals is preserved throughout the epidemic process. In Chapter Three, the impact of individuals who refuse to be vaccinated is explored. MMR vaccination and birth rate data from the State of California are used to determine the impact of the anti-vaccine movement on the dynamics of growth of the anti-vaccine sub-population. Dissertation results suggest that under realistic California social dynamics scenarios, it is not possible to revert the influence of anti-vaccine
contagion. In Chapter Four, the dynamics of Zika virus are explored in two highly distinct idealized environments defined by a parameter that models highly distinctive levels of risk, the result of vector and host density and vector control measures. The underlying assumption is that these two communities are intimately connected due to economics with the impact of various patterns of mobility being incorporated via
the use of residency times. In short, a highly heterogeneous community is defined by its risk of acquiring a Zika infection within one of two "spaces," one lacking access to health services or effective vector control policies (lack of resources or ignored due to high levels of crime, or poverty, or both). Low risk regions are defined as those with access to solid health facilities and where vector control measures are implemented routinely. It was found that the better connected these communities are, the existence of communities where mobility between risk regions is not hampered, lower the overall, two patch Zika prevalence. Chapter Five focuses on the dynamics of tuberculosis (TB), a communicable disease, also on an idealized high-low risk set up. The impact of mobility within these two highly distinct TB-risk environments on the dynamics and control of this disease is systematically explored. It is found that collaboration and mobility, under some circumstances, can reduce the overall TB burden.

Description
Sexual assault at colleges and universities in the United States is a significant health and human rights issue that impacts somewhere between one-in-four and one-in-five students. Despite the alarmingly high burden, overall rates of disclosing to crisis, health, and victim services, and reporting to schools and law enforcement remain low. In order to buffer students from associated short- and long-term harm, and help them reestablish safety and pursue justice, empirically-supported, innovative, and trauma-informed secondary prevention strategies are needed. To address this pressing issue, the current study used a trauma-informed, feminist community research approach to develop and design a prototype of an internet-based decision aid specifically tailored to assist students at Arizona State University who experience sexual assault with making informed choices about reporting and seeking care, advocacy, and support on and off campus. Results from preliminary alpha testing of the tool showed that: 1. It is feasible to adapt decision aids for use with the target population, and 2. While aspects of the tool can be improved during the next phases of redrafting and redesign, members of the target population find it to be acceptable, comprehensible, and usable.

Description
The purpose of this study was to examine the feasibility and preliminary efficacy of a theory-driven and a atheoretical reminder point-of-choice (PoC) prompt interventions on reducing workplace sedentary behavior in office workers with self-reported low usage (<4 hours per day) of their sit-stand workstations in the standing position. The design of this study was a cross-over trial including randomization into either the theory-driven or atheoertical reminder condition, after completion of a no prompt control condition. Participants (N=19) included full-time, primarily female, Caucasian, middle-aged office workers. The primary aim of this study was to assess the feasibility of these two PoC prompt conditions on reducing sedentary behaviors through the use of a Therapy Evaluation Questionnaire. The secondary aim of this study was to assess the preliminary efficacy of the two PoC prompt conditions on reducing sedentary behaviors relative to no-prompt control using the activPAL micro device. For the primary aim, descriptive means adjusted for ordering effect were computed. For the secondary aim, mixed-effects regression models were used to cluster for observations within-persons and were adjusted for age, gender, race, job-type, and ordering effects. During the no-prompt control, participants spent 267.90 ± 68.01 sitting and 170.20 ± 69.34 min/8hr workday standing. The reminder PoC prompt condition significantly increased sanding time (b[se] = 24.52 [11.09], p=0.034) while the theory-driven PoC condition significantly decreased time spent in long sitting bouts b[se] = -34.86 [16.20], p=0.036), both relative to no prompt control. No statistically significant reductions in sitting time were seen in either PoC prompt condition. Furthermore, no statistically significant differences between the two PoC prompt conditions were observed. This study provides feasibility insight in addition to objective measures of sedentary behaviors regarding the use of PoC prompt interventions in the workplace.

Description
Monitoring human exposure to chemicals posing public health threats is critically important for risk management and for informing regulatory actions. Chemical threats result from both environmental pollutants and elected substance use (e.g., consumption of drugs, alcohol and tobacco). Measuring chemical occurrence and concentrations in environmental matrices can help to pinpoint human exposure routes. For instance, indoor dust, a sink of indoor environmental contaminants, can serve to assess indoor air contamination and associated human exposures. Urban wastewater arriving at treatment plants contains urine and stool from the general population, the analysis of which can provide information on chemical threats in the community and ongoing harmful exposures. Analysis of sewage sludge can serve to reveal the identity and quantity of persistent organic pollutants in cities and inform estimates of toxic body burdens in local populations.
The objective of this dissertation was to investigate the occurrence and quantity of select, potentially harmful, anthropogenic chemicals in various environmental matrices and to explore the diagnostic value of analytical assays for informing public health decision-making. This dissertation (i) is the first to report spatio-temporal variations and estrogenic burdens of five parabens in sewage sludge from at the U.S. nationwide scale; (ii) represents the first China-wide survey to assess the occurrence and toxic emissions of parabens, triclosan, triclocarban, as well as triclocarban metabolites and transformation products contained in Chinese sewage sludge; (iii) documents the first use of a dispersive solid phase extraction method for indoor dust to measure dust-borne parabens, triclosan and triclocarban and estimating associated human exposures from dust ingestion; and (iv) is the first U.S. study to assess population-level alcohol and nicotine consumption in three U.S. communities using wastewater-based epidemiology (WBE). Obtained data on baseline levels of selected emerging contaminants in sewage sludge and indoor dust can serve to inform the future monitoring needs, risk assessment, and policy making. This work showcases the utility of WBE and urban metabolism metrology via dust and sewage sludge analysis to assess human behavior (e.g., drinking and smoking) and exposure risks more rapidly, efficiently and anonymously than traditional approaches can.

Description
Incarceration has a lasting and robust impact on individuals’ health, social support networks, and general well-being. Yet the role of carceral or personal factors in health outcomes remains unclear, particularly for racial and ethnic minorities. Prisons, with crowded living areas and shared bathroom facilities, invite the spread of infectious diseases such as hepatitis C and HIV/AIDS. The overwhelming majority of incarcerated individuals will eventually be released back to their communities, bringing with them any health-related issues acquired in prison and beforehand. This makes ex-prisoners’ health a correctional and public health and safety issue. Accordingly, this study seeks to advance our understanding and improve correctional policy by (1) assessing the factors that affect the adverse physical and mental health of returning prisoners, (2) determining how different types of social support (instrumental or emotional) and stress alter the relationship between health and positive reentry outcomes, and (3) examining how health, stress, and social support influence offending and drug use. The broader purpose of this research is to inform correctional policy and practice, engage public health concerns about ex-prisoners, and create a cost-effective model to decrease the stressors related to offender reentry, with the ultimate aim of reducing recidivism. The study includes 802 male ex-prisoners, with an original target sample size of 400 gang and 400 non-gang members identified using disproportionate stratified random sampling techniques. The study was conducted in cooperation with the Texas Department of Criminal Justice (TDCJ) in two prisons. Data come from the National Institute of Justice (NIJ) funded LoneStar Project and include a battery of survey questions about demographic information, physical and mental health, criminological theoretical constructs, release planning, criminogenic attitudes, and gang membership. The dissertation uses two waves of the LoneStar Project: an in-prison baseline interview, administered a week before release, and an interview administered over the phone at one month post-release. After conducting descriptive analyses, regression modeling will be used to assess the effects of the key independent variables on physical health and later, self-reported offending, net of appropriate controls. Results and relevant policy implications are discussed and should appeal to criminologists, health scholars, policymakers, and practitioners.

Description
In the United States, seasonal influenza is responsible for enormous medical costs and lost earnings as well as thousands of deaths. Medical masks are effective non-pharmaceutical preventions for minimizing the spread of illness in the event of an influenza outbreak. However, people in the United States rarely wear face masks the way many people in Asian countries do.
In a previous study of public response to the 2009 influenza A H1N1 pandemic, 71% of United States respondents supported the recommendation to wear a mask during the flu outbreak, while only 8% of respondents reported they wore a mask in public to protect themselves from getting sick. What are the factors that cause this gap? The purpose of this exploratory study is to identify barriers to the wearing of masks among adults in the United States.
The research was conducted through an online survey of 84 American residents via the Survey Monkey Audience service to collect their opinions on influenza, mask-wearing, and the perceived barriers to wearing face masks for flu prevention. The results are presented in the descriptive analysis and the non-parametric analysis.
The results showed a barrier against social interaction is a significant factor (p=0.003) regarding the impact between flu experience and the perceived barriers. The participants believed mask-wearing may lead other people difficult to perceiving their feelings. Regarding the relationship between mask-wearing experience and the perceived barriers, there were significant differences in perceived benefits (p=0.028), perceived risks (p= 0.003), and social value (p=0.021). Participants who have had worn masks had perceived higher benefits of mask-wearing, higher risks of catching the flu, and a higher agreement of importance to protect other people from getting the flu from them. The most common perceived barrier among the participants is product satisfaction. 85.71% of the participants agreed that wearing face masks is uncomfortable. 80.95% of the participants agreed with the importance to wear face masks as it protects other people from getting the flu from them, but only 37.5% of the participants with flu history had worn face masks.
By examining barriers to the wearing of masks for influenza prevention, this study can assess public willingness to adopt personal prevention behaviors and provide information for related policies in the future.

The United Nations projects that 68% of the world population will live in urban areas by 2050. As urban areas continue to grow, it is critical to consider how cities will be redesigned and reimagined to ensure that they are healthy and beneficial places that can properly support their residents. In addition, college students have been identified as a vulnerable population in regards to overall wellness. In Downtown Phoenix, one the biggest elements of concern will be the built environment and its influence on wellbeing as the city itself and Arizona State University’s Downtown campus populations continue to expand. Given this, the purpose of this study is two-fold. I applied Social-Cognitive Theory as a framework to first, understand student perceptions of the built and social environment and second, explore how perceptions of the built and social environment influence student wellbeing. I used semi-structured interviews and participant-driven photo elicitation to answer these questions. The study took place at Taylor Place Mall on Arizona State University’s Downtown Campus and participants were students who attend classes on the ASU Downtown Campus. Findings displayed the need for design considerations to focus on the safety of students, creating places to gather for social connection, and overall a desire for design to focus on place making and place meaning, as well as other themes. Understanding more clearly how the built and social environment guides behaviors and social opportunities can help urban designers, landscape architects, and community developers better plan healthier environments that foster productive behaviors, create meaningful spaces, and prove to be sustainable in future years.

Description
Objective: The Special Supplemental Nutrition Program for Women, Infants and Children (WIC) is a federally-funded program that provides supplemental food packages, nutrition education, and healthcare referrals to low-income women, infants, and children under 5, who are at the highest nutritional risk. This study explores if household WIC participation is associated with healthier dietary behaviors among age-ineligible children (5-18-years-old) in WIC households. Consumption frequency of fruits, vegetables, 100% juice, sugar-sweetened beverages (SSBs), and energy-dense snacks (sweet and salty snacks) among children from WIC and income-qualifying non-WIC households were compared.
Methods: Data were obtained from two cross-sectional panels (2009-10 and 2014) of the New Jersey Child Health Study conducted in four low-income New Jersey cities. Questions from previously validated surveys assessed consumption frequency of fruits, vegetables, SSBs, and sweet and salty snacks. Analyses were confined to 570 children between 5-18 yrs; of which 365 (5-11 yrs: 237, 12-18 yrs: 128) resided in WIC participating households and 205 (5-11 yrs: 138, 12-18 yrs: 67) in income-qualifying non-WIC households. Over half of the sample was African American and 43% were Hispanic. Multivariable analyses were conducted to compute incidence rate ratios (IRRs) using negative binomial regression to compare the differences in eating behaviors of children in WIC vs. Non-WIC households
Results: Household WIC participation was associated with a slightly higher frequency of vegetable consumption among 12-18-year-old children (IRR= 1.25, p=.05); differences were significant among older males (12-18-years-old) (p=.006), and not in females.
Frequency of 100% juice consumption was significantly higher among younger females (5-11-years-old) in WIC households who consumed juice about 44% more frequently (p=.02) compared to similar age girls in non-WIC households. Hispanic children in WIC households reported a lower frequency of SSBs consumption (p=.01); this association was only true among males (p=.02).
Conclusions: Household WIC participation is associated with healthier dietary behaviors among age-ineligible children living in the households, suggesting a positive spillover effect of the program. Proposed changes to WIC packages are likely to have dietary implications not only for WIC participants but also for non-participating children residing in WIC households,

Description
The purpose of this study was to evaluate the impact of a mentoring program on self-efficacy beliefs. High-risk undergraduate students at Arizona State University majoring in Public Health and other closely-related fields represent this study’s sample. Bandura’s Self-Efficacy Theory guides this study’s theoretical framework. This study used a mixed method, action research design. Participants took a pre-test that measures their self-efficacy and registered the barriers to their academic success; following that, they enrolled and participated in a mentoring program. Upon completion of the program, they completed a post-test to evaluate any changes to their perspectives. Non-parametric Wilcoxon signed-rank tests were applied to the surveys. Throughout the mentoring program, participants completed field notes and I completed a journal about our interactions. These, along with two focus group discussions, were analyzed using grounded theory in addition to the pre- and post-tests. The surveys found that the mentoring program impacted their self-efficacy in overcoming educational barriers the qualitative data showed a strong correlation between the intervention and perceived confidence. This included their perceived ability to perform difficult or unusual tasks, but also their ability to overcome barriers.
