Description
The objective of this case study is to understand the context for which process improvement is effective and the challenges of implementing change. In 2015, a major apparel retailer pioneered a value stream mapping project that addressed the order writing process between its merchandising team and an external vendor. This case follows the development and execution of the project and the challenge of sustaining the improvements rendered. Thorough analysis supports the recommendation for continued organizational support, a post-event auditing process, and specific metrics to indicate the project's success.

Description
Although the Leadership Scholarship Program has seen successful recruiting processes throughout changes in leadership of the program; the organization expressed a need for major overhaul to reevaluate the decisions of the process and to establish backing for those decisions. By asking current and alumni members of the program about what they would like to see in a future member of the program as well as which parts of the process they found most important, the qualities of a future member of the program could be established and weighted. The goals of the reevaluation were to help eliminate bias, discrepancies between applications with extremely different uncontrollable factors, define points of discrepancies, and establish organizational sustainability while achieving a 100% acceptance rate from offered students. Each of these goals was achieved through methods outlined in the LSP Selection Process Manual that was written as a result of this reevaluation. The manual also outlines ways to improve the process going forward.

Description
Camp Carey is an annual freshman orientation program that takes place before the beginning of the semester in late July and early August. As the incoming W. P. Carey classes continue to grow each year, so to does the size of Camp. Beginning this project, we looked at potential that we could directly impact the quality of the camp experience, and ensure that Camp remains a memorable and quality experience for all involved. Camp is directed and facilitated every year by W. P. Carey staff members and a group upperclassmen, the camp directors and facilitators. Due to the direct impact that these upperclassmen have on the camp experience, we decided to focus our attention on improving the training provided to these individuals, and to emphasize a process of continuous data collection and improvement. The director training is broken into three modules that focus on risk management, facilitator selection, and facilitator training. Each of the seven exercises in the director training is based on a tool or practice used by modern companies in project management and human resources management. They were designed with three goals in mind: to immediately increase the directors' level of preparedness for Camp, to produce a written record to be used by directors in subsequent Camp seasons, and to provide directors with an introductory level of experience with concepts and tools that will benefit them in their professional careers. The facilitator training portion centers around the creation of a 1 credit, repeatable hybrid course to both reward facilitators, train them in proper conduct and materials for camp, as well as collect valuable feedback from the facilitators. The creation of a larger spring training session, designed to prepare the facilitators for activity facilitation, emergency preparedness, and representing W. P. Carey and ASU, and the implementation of a summer review training session are designed to prepare facilitators to lead the best camp possible. Further, the essays and surveys involved in the class are set up to gather valuable information and feedback from the facilitators for further improving the program year-over-year.

Description
This study analyzes the various applications of Lean Methodologies in emergency departments (ED) from the years 2005 through 2010. These data were then used to create a predictive model that hospitals can use to assess the benefits of using lean within their ED. Metrics studied include 1) rate of patients that left the ED without being seen 2) length of stay and 3) overall patient satisfaction. These metrics were extracted from published studies and used to create a linear regression model, which could be applied to an ED to predict its status after implementing a lean project. After developing these formulas, they were applied to the ED of fictional hospital T-1 in order to predict benefit. After determining the approximate values for the post-lean metrics, an estimate of the financial benefit was developed in conjunction with a financial executive at Chandler Regional Medical Center, in Chandler, Arizona.

Description
This research focuses and discusses on the Supply Chain process within the mental health industry and its impact on the center for health empowerment education employment recovery. Our first approach was to research background information on mental health sector. With 115 billion dollars on mental health treatment investment annually nationwide, many citizens continues to struggle to find help. Due to such a complex structure of specific industry, we needed to focus more specifically, Arizona. Even within Arizona, we chose one organization to discuss their complex supply chain logistic issues. Through analysis of beneficiaries, technology system, finance management, employer, many educational programs, we were able to identify possible improvements. Through utilizing Supply Chain concepts, my co-author and I came up with few solutions that can greatly benefit the organization.

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.

Perfection is extremely difficult to achieve when playing team sports. This is especially true for lacrosse, a sport where dropped passes, missed shots and turnovers are prevalent even at the college and professional levels of the game. In order to improve on mistakes, teams must first recognize where the errors are being made. The purpose of this project is to implement the DMAIC process improvement method into lacrosse, with the goal of identifying and implementing improvements, leading to a more successful team.
In order to use DMAIC, lacrosse was expressed as a process that included five phases: offense, defense, riding, clearing and faceoffs. Data was gathered for each phase using game film from the Arizona State Men’s Club Lacrosse Team over the course of the 2019 and 2020 seasons. The data was then analyzed by comparing the output statistics of each phase to the goal differential, number of goals scored, and number of goals against. Once the areas of improvement were determined, additional analysis was done to determine why these certain areas needed improvement. The results provided what changes needed to be made in order to improve the team. In order to ensure the team sustained their success, control measures were put in place to determine what action needs to be taken and when.

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
As the need for data intelligence becomes more pervasive, companies are facing a shortage of professionals with sufficient analytical skills. It is more important than ever for students in traditional business management programs to understand relevant issues in data analytics. The paper, a teaching case, is split into two parts: the business case and the teaching note. The case addresses the challenges of an electric battery company, Capsule Inc., in adopting new analytics technology. The teaching note provides relevant management concepts and technology adoption framework to analyze the case in a class setting. The case can be used to introduce students to the challenges of implementing automation software in an office, as it focuses on key issues such as process improvement, technology adoption, and cost-reduction.

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.
