Description
Most reliable nutrition information can be found online, but it can be nearly impossible to differentiate from the unreliable blogs and websites that claim their information is correct. Because of this, it can be difficult for students to determine which information is true and which advice they will follow. During this time of growth and learning, it is essential that students have access to accurate information that will help them to be healthier individuals for years to come. The goal of this project was to provide students with an easily accessible and reliable resource for nutrition information that was presented in a simple and relatable way. The following videos and attached materials were created in response to ASU student needs and will be available for students on the ASU wellness website.

Description
Research shows that an effective method for decreasing bullying is for bystanders to intervene when they see bullying occur. If students are going to intervene they need to be able to not only recognize bullying, but also have strategies to combat it. Students should be able to get this information from their teachers. However, preservice teachers who will one day have their own classroom do not have knowledge of bullying and upstander behavior. We created an online training for preservice teachers to increase their knowledge of bullying and upstander behavior so they could share these practices with their future students and in turn their students could become upstanders and decrease bullying incidents. Implications for future research and policy include repeating the study over a longer period of time, and the inclusion of upstander behavior training into existing preservice teacher training programs.

Description
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
Background: The purpose of this study was to assess the efficacy of a lifestyle intervention on cardiorespiratory fitness in Latino youth with obesity and prediabetes. <br/>Methods: Participants (n=50) in this study were taken from a larger randomized controlled trial (n=180, BMI ≥ 95th percentile). Youth participated in a 6-month lifestyle intervention that included physical activity (60 minutes, 3x/week) and nutrition and wellness classes (60 minutes, 1x/week) delivered to families at the Lincoln Family YMCA in Downtown Phoenix. The primary outcome was cardiorespiratory fitness measured at baseline and post-intervention.<br/>Results: The mean BMI for the sample was 33.17 ± 4.54 kg/m2, which put the participants in the 98.4th percentile. At baseline, the mean VO2max was 2737.02 ± 488.89 mL/min. The mean relative VO2max was 30.65 ± 3.87 mL/kg/min. VO2max values significantly increased from baseline to post-intervention (2737.022 ± 483.977 mL/min vs 2932.654 ± 96.062 mL/min, p<0.001). <br/>Conclusion: Culturally-grounded, family-focused lifestyle interventions are a promising approach for improving cardiorespiratory fitness in high-risk youth at risk for diabetes.

Description
This research aims to develop an understanding of how interventions designed to improve water quality in buildings can be used to mitigate Legionella pneumophila concentrations. Intervention methods can be described as any approach that can be used to improve microbial water quality. In order to provide a foundation of background knowledge, a literature review was conducted to identify similar studies and collect relevant and timely research similar to the subject. The information gathered from the literature review was used to structure the sampling process and parameters. Using the research collected from the literature review, a review table was created to summarize the differences in the studies conducted and to determine research gaps. To categorize the studies, intervention methods, contaminants addressed, and water quality meta-data were differentiated for each of the articles. For the purpose of the sampling process, the three interventions analyzed consist of flushing, water heater set point change, and both flushing and water heater set point change. The locations of the sampling consisted of the city drinking water inlet, the basement janitor's closet, basement shower, 2nd floor, 3rd floor, and 7th floor break rooms and restrooms of the Interdisciplinary Science and Technology Building IV at ASU. For the flushing intervention, the sampling results demonstrated an increase in free and total chlorine concentration post flushing which aligns with the research found in the literature review. In addition, it was observed that iron concentrations drastically increased for both the cold and hot water by flushing. There was a significant decrease detected for ATP concentrations post flush in the hot line. However through the sampling session, the flushing intervention did not yield statistically significant results for Legionella concentrations.

Description
Human beings are social creatures and need social connections to thrive in society. I observed low social connectedness amongst the students with disabilities in my high school and wanted to do more research on the cause of this occurrence. In my literary analysis and proposal, I highlight the effects social isolation and loneliness have on the well-being of people. While concluding that negative health effects come from low social connection, I researched the prevalence of low social connection amongst the disabled population and found that although low social connectedness can impact anyone, those with disabilities experience more low social connectedness than those without disabilities. I then analyzed ways in which low social connection can be addressed and focused on measuring social isolation and loneliness as indicators of low connectedness. I proposed a promising mentorship program intervention for my chosen population, young adults with disabilities, to help them increase social connection. This proposal may be adapted for use with any population. My goal for this program is to help increase social connection, promote societal support, and increase self-esteem and knowledge of their desired career and life skills as they transition into adult roles. Furthermore, I hope this paper may help spread awareness and get society to think of ways interventions to promote social connectedness can be implemented for people, like young adults with disabilities, who experience low social connectedness.

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.

Description
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.

Description
This thesis examines the current state of intervention in developing countries that are suffering from human rights abuses, mass killings, and/or politicide. The first part of this thesis will be a brief examination of present-day United States intervention efforts in order to understand the decision making and reconstruction process within the status quo. This will also be done by looking at the global community´s preferred form of intervention and how the United States aligns with these standards such as those represented in the Responsibility to Protect. Secondly, this thesis aims to remodel the reconstruction process in order to conceptualize the addition of mental health first aid. This will be presented by first analyzing the importance of mental health aid and then looking at the specific diagnoses that concatenate with trauma. This thesis argues that current reconstruction efforts are insufficient without the implementation of psychological aid. Without adding psychological aid, countries are more likely to return to cycles of violence that were present pre-intervention. Public policy should change to include aiding civilians, not only physically, economically, or militarily, but also by including psychological aid. Implementing behavior health specific aid in developing countries may potentially be the missing component to lasting change that countries need in order to sustain political sovereignty and support community efforts to rebuild. This research, therefore, aims to bridge important gaps between United States intervention efforts, public policy and mental health.

Description
This thesis seeks to analyze the phenomenon of increasing multipolarity in the global environment vis-à-vis the conduct of humanitarian intervention. Established powers, including the United States and United Kingdom, and rising, predominantly developing states seem at odds over where to intervene, when, and on what basis. Situating this conflict within the responsibility to protect (R2P) doctrine, which has been the guiding international framework for intervention over the past decade-and-a-half, the research answers whether the processes of multipolarity will ultimately lead to the reconciliation of nation-state interests (cooperation) or unreconciled divergence (competition). Using United Nations Security Council resolutions to temporally track multipolarity and map nations’ language into the rhetorical spaces of humanitarianism and inclinations toward intervention, the research finds support for the proposition that concepts of humanitarian intervention between great and rising powers are more conflictual. Furthermore, nations appear to be clustering into “camps” along broadly humanitarian/interventionist and state sovereigntist lines. To preserve humanitarian intervention in a more multipolar world, its proponents must accommodate diverse nation-state interests, facilitate improved relations among the member states of the U.N. Security Council, and empower regional bodies as partners in alleviating conflict under an R2P mandate.
