Description
While type 2 diabetes (T2D) rates have soared, the number of Americans classified as ‘prediabetic’ has also increased. Despite this, current preventative approaches are costly and often not without undue side-effects. Instead, behavioral lifestyle approaches hold promise in reducing conversion rates of T2D as the latest treatment option that could mitigate and transform disease management. However, present interventions do not possess the scope necessary for implementation in a realistic, scalable way that can target the large at-risk population.
The application (app) “BeWell24” mitigates this diabetes risk through targeting sleep, physical activity, sedentary behavior, and diet, and is being delivered through mHealth technology to attenuate the higher-risk of the prediabetic Veteran population. In order for full scale dissemination, this thesis examines a provider perspective of the ‘Post-intervention interview guide’, performed with a Phoenix Veterans Affairs Health Care System (PVAHCS) provider. It then suggests revisions to the interview guide based on the provider’s interview and existing literature. This thesis also emphasizes the rationale behind these proposed changes to be organized in line with the iPARIHS framework (integrated Promoting Action on Research Implementation in Health Services).
Overall, the provider responded positively to BeWell24 and the ‘Post-intervention interview guide’, with constructive suggestions for each question in the interview guide. The main theme of the provider’s answers and comments were to prioritize efficiency and preserve standard clinical flow. A revised interview guide is provided, which prospectively presents as a more brief and focused interview organized by the iPARIHS framework. This revised interview guide could aid in the clarity of provider responses, specifically for the prospective interviews of the ongoing larger BeWell24 study and future studies.

Description
In this research paper I combine statistics from various reports and studies with around 20 different interviews with female journalists to understand how women are faring in national and local television newsrooms in 2019. I explore issues such as the pay gap, sexual assault, the importance of appearance, balancing work and family life and obstacles that women of color uniquely face. I spoke with women from various cultural backgrounds, experience levels, and in different positions within their newsrooms. Through my scholarly research and 19 interviews with women who either currently work at NBC News in New York City and women who currently or recently worked at 12News, the NBC affiliate in Phoenix, I conclude they share similar stories of oppression, sexism and issues. However, women have made more progress in local markets and have more opportunities when compared to the national level. I also explore reasons for why this disparity is happening and why local newsrooms seem to have more women represented through their on-air talent than national newsrooms do. One of the reasons I concluded for this include, how local newsrooms have a better understanding of their audience members thus making them more able to reflect their talent to their diverse audience. Another factor that might play a role in this disparity includes, the historical factor and societal norm of seeing men in higher positions and authoritative roles, such as being an anchor, at the network level. Lastly, the idea of how family and having children impacts women’s careers more than men. This can lead to less women pursuing a job at the network since they must spend time raising a family and have the ability and flexibility to do that easier at the local level. Overall, I focused on the barriers, obstacles and stories these women have had throughout their careers all while looking at it from both a local perspective and a national one.

Currently conventional Subtitle D landfills are the primary means of disposing of our waste in the United States. While this method of waste disposal aims at protecting the environment, it does so through the use of liners and caps that effectively freeze the breakdown of waste. Because this method can keep landfills active, and thus a potential groundwater threat for over a hundred years, I take an in depth look at the ability of bioreactor landfills to quickly stabilize waste. In the thesis I detail the current state of bioreactor landfill technologies, assessing the pros and cons of anaerobic and aerobic bioreactor technologies. Finally, with an industrial perspective, I conclude that moving on to bioreactor landfills as an alternative isn't as simple as it may first appear, and that it is a contextually specific solution that must be further refined before replacing current landfills.

Description
A Conversation on Stuttering is a documentary film that is aimed at raising awareness about stuttering. Still not fully understood by modern research, stuttering (stammering in the UK) is a diagnosis often accompanied by years of ridicule, shame, and misconceptions. We set out to interview people who stutter, researchers, and clinicians alike to gain insight into the impact stuttering can have. Our participants in this documentary included four people who stutter, two clinicians, and 2 researchers (one of them being a person who stutters). The questions asked ranged from topics of physical and emotional aspects of stuttering to therapy experiences and research on what causes stuttering. From the mix of genuine, sometimes emotional, responses, the film captures flowing conversation on a range of experiences had by our interviewees. Through these responses, we hope to open further dialogue about the themes of identity, understanding our differences, and perspectives that can make a more accepting world.

Characterization and Manipulation of Microbiomes From Arid Landfills for Improved Methane Production
Description
Environmentally harmful byproducts from solid waste’s decomposition, including methane (CH4) emissions, are managed through standardized landfill engineering and gas-capture mechanisms. Yet only a limited number of studies have analyzed the development and composition of Bacteria and Archaea involved in CH4 production from landfills. The objectives of this research were to compare microbiomes and bioactivity from CH4-producing communities in contrasting spatial areas of arid landfills and to tests a new technology to biostimulate CH4 production (methanogenesis) from solid waste under dynamic environmental conditions controlled in the laboratory. My hypothesis was that the diversity and abundance of methanogenic Archaea in municipal solid waste (MSW), or its leachate, play an important role on CH4 production partially attributed to the group’s wide hydrogen (H2) consumption capabilities. I tested this hypothesis by conducting complementary field observations and laboratory experiments. I describe niches of methanogenic Archaea in MSW leachate across defined areas within a single landfill, while demonstrating functional H2-dependent activity. To alleviate limited H2 bioavailability encountered in-situ, I present biostimulant feasibility and proof-of-concepts studies through the amendment of zero valent metals (ZVMs). My results demonstrate that older-aged MSW was minimally biostimulated for greater CH4 production relative to a control when exposed to iron (Fe0) or manganese (Mn0), due to highly discernable traits of soluble carbon, nitrogen, and unidentified fluorophores found in water extracts between young and old aged, starting MSW. Acetate and inhibitory H2 partial pressures accumulated in microcosms containing old-aged MSW. In a final experiment, repeated amendments of ZVMs to MSW in a 600 day mesocosm experiment mediated significantly higher CH4 concentrations and yields during the first of three ZVM injections. Fe0 and Mn0 experimental treatments at mesocosm-scale also highlighted accelerated development of seemingly important, but elusive Archaea including Methanobacteriaceae, a methane-producing family that is found in diverse environments. Also, prokaryotic classes including Candidatus Bathyarchaeota, an uncultured group commonly found in carbon-rich ecosystems, and Clostridia; All three taxa I identified as highly predictive in the time-dependent progression of MSW decomposition. Altogether, my experiments demonstrate the importance of H2 bioavailability on CH4 production and the consistent development of Methanobacteriaceae in productive MSW microbiomes.

Zero-Valent Metals (ZVM) are highly reactive materials and have been proved to be effective in contaminant reduction in soils and groundwater remediation. In fact, zero-Valent Iron (ZVI) has proven to be very effective in removing, particularly chlorinated organics, heavy metals, and odorous sulfides. Addition of ZVI has also been proved in enhancing the methane gas generation in anaerobic digestion of activated sludge. However, no studies have been conducted regarding the effect of ZVM stimulation to Municipal Solid Waste (MSW) degradation. Therefore, a collaborative study was developed to manipulate microbial activity in the landfill bioreactors to favor methane production by adding ZVMs. This study focuses on evaluating the effects of added ZVM on the leachate generated from replicated lab scale landfill bioreactors. The specific objective was to investigate the effects of ZVMs addition on the organic and inorganic pollutants in leachate. The hypothesis here evaluated was that adding ZVM including ZVI and Zero Valent Manganese (ZVMn) will enhance the removal rates of the organic pollutants present in the leachate, likely by a putative higher rate of microbial metabolism. Test with six (4.23 gallons) bioreactors assembled with MSW collected from the Salt River Landfill and Southwest Regional Landfill showed that under 5 grams /liter of ZVI and 0.625 grams/liter of ZVMn additions, no significant difference was observed in the pH and temperature data of the leachate generated from these reactors. The conductivity data suggested the steady rise across all reactors over the period of time. The removal efficiency of sCOD was highest (27.112 mg/lit/day) for the reactors added with ZVMn at the end of 150 days for bottom layer, however the removal rate was highest (16.955 mg/lit/day) for ZVI after the end of 150 days of the middle layer. Similar trends in the results was observed in TC analysis. HPLC study indicated the dominance of the concentration of heptanoate and isovalerate were leachate generated from the bottom layer across all reactors. Heptanoate continued to dominate in the ZVMn added leachate even after middle layer injection. IC analysis concluded the chloride was dominant in the leachate generated from all the reactors and there was a steady increase in the chloride content over the period of time. Along with chloride, fluoride, bromide, nitrate, nitrite, phosphate and sulfate were also detected in considerable concentrations. In the summary, the addition of the zero valent metals has proved to be efficient in removal of the organics present in the leachate.

News headlines are filled with unequal treatment in the workplace. However, there are also inspirational stories that encourage young women to face the challenges they are presented as they become executives in corporate America.
The purpose of this study was to interview women executives within corporate America to identify similar means of navigating women-specific issues they may have been presented with within their industry. More specifically, the questions sought to identify how these women became successful within their industry and how their female identities may have provided benefits to them, professionally. Interviewees were selected on a multitude of factors, title and status in company, industry, including availability, mutual connections, and demographics. Interviews were conducted both in person, over the phone, via web video conference and via email. All interviewees were asked the same questions, and interviews ranged from 25-45 minutes each. Each one was recorded and transcribed in order to facilitate comparison between stories, experiences, and other mentions.
The initial intention of analyzing the interviews and stories of these executives was to identify common factors that unified their stories. There were nine categories that the interviews sought to investigate: work-life balance, starting off strong, daily routines, mentorship/support, leadership, impact and legacy, advice and motivation, pros of being a woman, biggest challenges/cons. However, the interviews revealed that there were a plethora of unique factors that identified the stories these women had to tell. Overall, 5/8 of the executives believed that their female identity provided an advantage to them in the corporate sector, 2/8 women said their identity was a neutral factor, and only one woman stated she felt it placed her at a disadvantage. Further, this study concludes that the stories of impenetrable glass ceilings and roadblocks are balanced to some degree by stories of success within the corporate sector. There were 3 key themes for their narratives for success, having a support system, putting yourself first, and giving back.

Description
In April of 1994, a genocide broke out in Rwanda that lasted about 100 days and killed approximately 800,000 men, women, and children (Krain, 2005). Over the course of the last seven months we worked with a Rwandan refugee to bring this project to fruition. This refugee inspired us to show the personal side of the issue of resettlement and we believed that she would be able to make an impact on others if we could share her story. The purpose of this project was to record this refugees story of resettlement in America. As mentioned above, we wanted to share their powerful journey from Rwanda to America. We believed that by introducing a personal story to a relatively impersonal matter we would bring more understanding to this issue. We wanted to create a project that could not only be a source of education, but also have a personal aspect that would inspire many to learn more and get involved with issues that are important to them. We believed creating this short film would be the best way we could have this story reach more people. Over these seven months, we created a short film that told the story of the Rwandan genocide and the American resettlement process from the unique perspective of someone who has experienced both.

Description
Fantasy football exists as a thought-to-be male dominated space, particularly with respect to the linguistic practices of players. Heteronormativity runs rampant, and fantasy players are not held accountable for the implications of their language. This essay analyzes what the dynamics of fantasy football leagues are, how current linguistic practices shape them, and suggests that women’s participating in fantasy football leagues functions as a type of trash talk that encourages men to address their internalized heteronormativity and create a more welcoming and progressive experience for people of all genders.
