Description
Research has found there is a lack of women present in the IS industry. In order to combat this problem, this research examines why women are not choosing IS majors at the university level. At Arizona State University, the Computer Information Systems undergraduate degree program is only 23 percent female. Many different factors can influence the decision to choose a major, so survey methodology was used to ascertain what factors were the most important to different demographic groups when making this decision. The study found no significant gender difference when making this decision, but rather a difference between specific majors. Genuine interest, interesting work and high career earnings were identified as the most influential reasons for choosing a college major. The results were used to create recommendations for the IS Department at ASU to implement in the next year and encourage more female participation in the CIS undergraduate degree program.

Description
In this thesis a community-based ride sharing mobile application, Ride Devil, will be introduced and created to provide services for communities such as Arizona State University and its students, faculty, and other affiliates to find safe rides around campus because campus population problem exists. This causes increased transportation costs, decreased parking space availability, and more transportation issues. The Ride Devil application itself is based off on the ride-sharing concept of transportation as introduced, above. Students, faculty, and other university affiliates will drive their own vehicles and use the Ride Devil services in order to coordinate pick-ups with members of its community. Not only is this form of transportation more cost effective than competing transportation models, taxis, but it also promotes safety, community, and educational assistance.

Description
Theft as well as burglary rates have remained high all across the world. These thefts involve stealing expensive objects like cars, or breaking into homes and stealing televisions, or going to malls and shoplifting. Aside from these kinds of crimes, theft involving personal items like backpacks, laptops, or mobile devices is just as important. Travelers and students can be subjected to these kinds of thefts easily and unnoticeably. According to a report from Kensington IT, an estimated one laptop is stolen every 53 seconds, 70 million smartphones are lost each year, and 52% of devices are stolen from the office/workplaces with 24% from conferences. One way to protect these items is to use a security device to ensure greater safety. The iMovedAlarm is an affordable sensor alarm that notifies people when their belongings are being stolen while also deterring thieves from stealing those belongings. The iMovedAlarm is a module that consists of a sound alarm, an LED light, and sensor technologies that activate when an object leaves the vicinity of the owner. When a thief attempts to steal the object, the iMovedAlarm will know to sound a buzzer alarm, flash an array of LED lights, and send alerts to a user's smartphone or wearable devices. This can help deter a thief from continuing the crime as those around him or her will have a better notice of what is happening. In addition, if the thief continues on with stealing the item, the iMovedAlarm can be tracked with the user's smartphone so that the location of the items can be found. The iMovedAlarm utilizes Arduino technology to make the device even more user-friendly.

Description
How prepared are individuals to work in an environment with sensitive information? Do business students believe a data security course would be a valuable addition to their curriculum? This study investigates W.P. Carey's role in preparing its students for jobs in which they most likely will have to handle large amounts of important data. Roughly 500 students across varying majors and years of education in the W.P. Carey School of Business answered an assortment of questions on their computer habits, and responded to various scenarios to test their knowledge. The survey targeted three specific areas (Software Updates, Password Protection, and Phishing) which was believed to be most pertinent to the students' future roles as professionals. While a large number of those surveyed (roughly 65%) responded well to most questions, nearly a third of all the responses received indicated cause for concern or an indication of a lack of knowledge. It was suggested (and many respondents agreed) that further education be provided to students for their own well-being in addition to the wellbeing of their future employers.

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
We created a sufficient database that can be used by the SDA for extensive analysis as well as a starting foundation for further development. The design of the database revolved around the men’s basketball team and includes data for conferences, teams, players, and the historic schedule of teams past performances. This design can be used as a template for future sports that would like to be added to the database. The queries we ran that tested the functionality of the database show the utility and accessibility that is possible with the data currently in the database. The visuals included assist our examples by exhibiting how the results gathered by the queries can be transformed into figures that may be more visually appealing than the raw data. We came up with example questions that could be potential questions the SDA may have regarding current and past performance statistics. We expect that as a continuation of this project, the SDA will be able to utilize it to their advantage to analyze and improve the performance levels of other teams.

Description
While Covid-19 had severe impacts on education across the board, the goal of our research is to examine how virtual learning affected Business Data Analytics and Computer Information Students at Arizona State University. A survey was created to measure three key academic areas (student learning, communication, and student engagement) that may have experienced a notable change in quality. Forty Nine W.P. Carey students were surveyed and their responses were recorded in a Google Sheet. From there the results were transferred to excel and converted into a Numeric Likert scale. By establishing base scores for each of the survey statements we can isolate areas of virtual learning that underwhelmed or satisfied our target demographic. The objective of the subsequent analysis was to identify any areas within the three focal points that participants felt strongly impacted their performance with virtual schooling during the August 2020 to May 2021 school year.
