Description
Science communication to the public can help create informed citizens and help bolster professional creativity and skills. A method for exploring this discourse is through art and multimedia. In this study, online educational videos were created to test whether specific misconceptions about biological evolution could be effectively addressed while also engaging the viewer. Two short videos (~5 minutes total) were created and hosted on a website where participants could access the videos. Survey questions were provided before and after the videos to test participants' learning abilities. Additional survey questions asked for participants' opinions and experiences with the videos to gauge engagement. Overall improvement was observed in participants' learning and engagement with the videos but with variable levels of understanding and suggestions for better experience. Future work will focus on improving the quality of the video content as well as the level of engagement between participants and media.

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
Most individuals entering college are taking responsibility for their own health for the first time. Students are used to having a parent or guardian nearby to diagnose and provide remedies for common health issues. Entering college, whether in a different city or just down the road, means they must assume those responsibilities themselves. Navigating that transition can be difficult for college students. A large majority of students turn to internet health resources, such as WebMD, for health information. However, studies show that despite overall internet savvy, college students are not very skilled at finding legitimate health information online. Therefore, a health resource designed specifically for college students would be a valuable resource for many students at ASU. Working with local Phoenix physician Doug Lakin, I and a team of other Barrett students revised Dr. Lakin's healthcare guide, Thrive 101: Health & Wellness for College Students. I was responsible for the guide's second chapter, which provides information on specific illnesses and injuries. I conducted a literature review to discover the best practices for communicating medical information. I found that using short sentences, simple words, bullet point lists, numbered lists, and subheadings improved the effectiveness of a health resource. I also found that health information seekers want resources to be tailored specifically for them. They want personalized resources. Personalization means including health information that the intended reader wants, excluding the health information the reader does not want, as well as featuring personal anecdotes from individuals like the reader dealing with health problems like the reader's. I applied what I discovered to Thrive 101. I reorganized the chapter I was assigned, incorporating subheadings and clear organization of the information. I also eliminated information I judged irrelevant to college students and brainstormed what information was missing that college students would benefit from. At this time, the revision team has not gotten to the point where we are researching and writing new information, but we do have lists of items we want to include. The information already in the guide I reformatted into bulleted and numbered lists where possible. As with the new information, we have not begun to revise the guide on a prose level, shortening the sentences and simplifying the vocabulary, but we intend to work into the summer to finish our revisions.

Description
Communication skills are vital for the world we inhabit. Both oral and written communication are some of the most sought-after skills in the job market today; this holds true in science, technology, engineering and mathematics (STEM) fields. Despite the high demand for communication skills, communication classes are not required for some STEM majors (Missingham, 2006). STEM major maps are often so packed with core classes that they nearly exclude the possibility of taking communication courses. Students and job seekers are told they need to be able to communicate to succeed but are not given any information or support in developing their skills. Scientific inquiry and discovery cannot be limited to only those that understand high-level jargon and have a Ph.D. in a subject. STEM majors and graduates must be able to translate information to communities beyond other experts. If they cannot communicate the impact of their research and discoveries, who is going to listen to them?<br/>Overall, the literature around communication in STEM fields demonstrate the need for and value of specific, teachable communication skills. This paper will examine the impact of a communication training module that teaches specific communication skills to BIO 182: General Biology II students. The communication training module is an online module that teaches students the basics of oral communication. The impact of the module will be examined through the observation of students’ presentations.

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
My thesis/creative project is a series of videos, supplemented by a paper documenting all the research. The project focuses on domestic and feral cats through the viewpoint of the “warrior cats” book series. The use of a particular fandom as a vehicle for science communication is a unique platform for use as a thesis/creative project. The narrated videos are made with the intention of being presented on YouTube or a similar viewing platform to an audience that is already familiar with the book series. The videos would fit on the site as a form of educational film known as video essays. The videos cover a range of topics to relate this book series to real situations with domestic animals, particularly cats, and wildlife. Each video is around ten to twenty minutes long and presented as episodes in a series.
The objective of my thesis project is to help bridge the gap between entertainment and science. I grew up reading the warrior cats, and I assume I was similar to many other children and young teens who did not understand domestic cats or ecology enough to question anything in the books. I know that much of these books are fictional, but that does not mean that it can’t be analyzed and used as a tool for teaching. The goal is to reach common ground with those people who have an interest in the warrior cats series, and help them understand it in a new light, as well as the world around them. I aim for the takeaway of this series to encourage people to explore the concepts I discuss and consider expanding upon the ideas within the Warriors universe or with their own cats.

Forensic science is the application of science to matters of law, especially criminal investigation and procedure. ForenSICK Science, on the other hand, is an educational YouTube channel. It was created in early 2019 after listening to two people on a podcast confidently preach surprisingly inaccurate information about forensic science. My goal in the creation of the channel was to give people the proper information regarding the practice. This goal grew to encompass several different fields including continued education practices, informal and nonformal learning, and combating “science speak.” Using YouTube as a tool in this journey was the first step in combating forensic inaccuracies.

Description
The process of communicating science between the general public and scientific community has been marked by several challenges in the modern setting. Namely, scientists’ trepidation toward misinterpretation, jeopardization of professional reputability, and perception of two distinct arenas of communication has led to the perpetuation of the deficit model of communication. This model is exceptionally limiting as it effectively removes the scientists from the public sphere and can have devastating societal repercussions. The dialogue model of communication is a much more effective communicative model for the modern setting but has been met with resistance in its adoption. As communication as a whole is grounded in multiple foundational disciplines of psychology, philosophy, linguistics, and other fields, it would be apparent that the adoption of the principles of polymathy would serve to better prepare scientists to engage in mass communication with the public. As polymathy is a lifelong pursuit, the implementation of narrative training into collegiate undergraduate science curriculum would serve as a particularly potent beginning. That is, narrative's ability to reach near-universal audiences, enhance the recall and comprehension of complex subject matter, and forge an empathetic connection essential to effective communication is uniquely suited in ensuring a more effective communicative dynamic between the scientific community and the general public. As such, this thesis serves to advocate the adoption of narrative-based communicative training into undergraduate science curriculum not as separate courses, but rather as direct incorporation. This would serve to both revitalize polymathy in the modern age and prepare the next generation of scientists to be better equipped for the public dialogue.

Description
Cosmic horror distinguishes itself from standard horror in large part because of the things that it finds horrifying. Cosmic horror, like any horror, attaches itself to external experience. Powerful technologies’ ability to reshape our perspective are the ideal choice for this anchor point. Beyond the Wall of Sound is a podcast that seeks to unify the existential dread and scientific imaginings inherent in cosmic horror and weird fiction, with dystopian visions of technological futures. The podcast uses the strange and horrifying mind of HP Lovecraft, as revealed through his short stories, to shed light on the horrifying, revealing and absurd imaginaries that drive and emerge unintentionally from current pursuits in science and technological innovation. In this essay, I describe the roots of horror and its relevance and therefore applicability to human experience. I then exemplarily relate the practical mode of thought that created one of the podcast’s episodes, which take’s Lovecraft’s The Thing on the Doorstep and the authors fears of the future as a lens to discuss and reflect upon the technology of body switching. The podcast is presented as an important piece of science communication in the face of increasing misinformation and a rolling technological wave. The project is affected by the strength of Lovecraft’s influences over time, and ultimately is itself a vehicle for and a deconstruction of that influence. Ultimately, the purpose of this podcast is not to horrify, but to inspire people to do good and remain educated despite the horrors of a pessimistic and uncaring existence.
