Description
The thesis "How Professional Artists Can Better Promote Themselves Online" aims to create a solution to improve artists' online sales and exposure. With the Internet being such a congested platform, I began to wonder how it was possible for artists to stand out from the crowd. I conducted six in-depth interviews in order to form a better understanding of what problems and frustrations artists currently faced everyday online. The data I collected from these interviews transformed my thesis into an entrepreneurial venture, and the iPhone app Artello was born. I created an entire working prototype of my app using Keynotopia. Artello's mission is to build an interactive art community that will create and foster relationships between artists and buyers like never before. This platform illustrates to buyers an artist's personality, style, and individual story. With Artello's guidance, artists will form stronger relationships with art buyers, connect with similar artists, and create a compelling online presence.

A cost analysis was done on the participant recruitment for an ongoing research project to promote colon cancer screening in Phoenix, Arizona. The aim of the 5-year project is to navigate people, who do not regularly see primary care physicians, from the community to a nearby clinic to be screened, using an intervention strategy called tailored navigation. Through tailored navigation, participants' barriers to being screened are addressed by Community Health Navigators, who call the participant over the span of 8 weeks following an initial class at a community site and give them information on how to overcome his or her specific barrier. The objective of this cost analysis is to explore the costs of recruiting a participant from the community to the initial class to a potential program manager. The process of recruitment involved recruitment of a community site, project introduction, the sign-up of interested participants, eligibility, baseline, and consent tests, and the class itself. A Community Site Liaison recruits sites and schedules class times. The Community Health Navigator conducts eligibility, baseline, and consent surveys and teaches the class, a sixty minute presentation on colon cancer screening. The cost of recruitment per community site was $541.23, and the cost per participant attending class was estimated to be $1,594.41 per participant with variation between $1,379.97 and $1,770.71 in optimistic and conservative scenarios, respectively.

Description
Information technology has become an increasing popular major offered by various universities, and provides the student with notable flexibility regarding courses as there are multiple career paths to suit the person’s specific technical interests. However, the methods universities use to promote their majors, including IT, are not as effective as it needs to be. The mediums currently used are mostly comprised of brochures, flyers, a single web page from the university’s entire website, and some communication with advisors, among others. This can be an issue for many readers as the information is often brief, providing only summaries of what can be expected, and ambiguous statistics that may not accurately or completely reflect the prospects of graduates looking to make a living the rest of their adult lives. This could cause some students to choose a major that may not be their best fit, and changing majors later will be very costly and delay graduation by one or more years. Therefore, the advocation of majors will have be rethought. The IT major offered at ASU is a perfect opportunity to determine whether a major can be promoted through a different approach with a senior capstone project involving a website. This Barrett creative project will act as a subset of the capstone project that will explore an attempt at introducing in interactive element to the website that allows prospective students to get a brief introduction to the computer networking aspect of IT, which includes a real world introductory game, along with more detailed exercises if the user is interested.

Description
Short-term medical volunteer work via a nongovernmental organization is a popular tool for students in the health care field to gain experience, while further providing communities that normally lack health care options the opportunity to receive free care. One such organization, VIDA Volunteer Travel, has been successful in implementing this model in Central America. However, organizations of this form have not been evaluated for effectiveness or improvement. This exploratory study examines the effectiveness of VIDA based on six qualifying characteristics that make up a successful NGO. The researcher conducted in-depth, semi-structured interviews with 21 individuals, including VIDA staff members in Costa Rica and Nicaragua, health professionals working for VIDA, local community leaders, and volunteers participating in VIDA's programs. Summaries and quotes of these interviews were uploaded and analysed using Atlas.ti to identify common words and themes from the interviews. Informants frequently identified the organization as sustainable, both from a fiscal and ecological standpoint. The organization also successfully managed volunteers, although post-trip follow-up was lacking. Adherence to the mission statement and distribution of supplies allowed for improved organization and successful structure of the organization. Education and health promotion was also emphasized, although implementation of this education into the communities was lacking. Collaboration with the community and volunteers allowed for stringent, successful treatment to be given to patients, and ethical guidelines set up by the organization allowed for self-governance and improvement of the NGO. This study suggests future research opportunities for the organization, to evaluate its own impact and opportunities for improvement. Furthermore, suggestions are addressed that allow the organization to improve upon its well-implemented infrastructure, and allow for future organizations to use VIDA as a model for improvement.

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.

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
Hospitalized and chronically ill infants are at risk for motor, cognitive, and social developmental delays. Nurses have an important role in supporting infant and family development to mitigate these delays. A literature review was performed to identify nursing interventions that promote development in these three categories. After literature was selected, critical appraisals were performed to assess the quality of evidence. Breast feeding, early cognitive-motor intervention, and family centered care were found to be beneficial for promoting motor development. Maternal scaffolding, responsive-didactic caregiving, and skin-to-skin contact are recommended nursing interventions for cognitive development. Lastly, integration of music is the nursing intervention recommended to promote social development.
