Expulsion from school is life changing. This single event can alter the trajectory of a student's life--for better or for worse. How life changes is unique for each individual student. Risk and protective factors that impact an individual student's resilience determine the level of positive or negative outcomes experienced as a result of expulsion. Educators have the opportunity to take advantage of this disruption in students' education to improve the trajectory of students' lives. However, without thoughtful intervention from caring educators, this interruption in students' education may have an irreparable destructive impact on students' future. The purpose of this study was to understand the expulsion experience from the point of view of the student in order to represent this critical stakeholder group in future policy and program development, implementation, and decision-making. Students' narratives are a means for members of the educational community to access students' experiences and perceptions in order to understand the impact of expulsion on students' lives. Students' perspectives are presented through thick description in this narrative case study. The experience of these eight students is evidence that expulsion can change students' lives in a positive way. Knowing this, responsible educators must develop interventions for expelled students that channel the positive life-changing potential of this experience. Educators must develop interventions focused on bringing forth protective factors that are documented to increase resilience and to make students less susceptible to the risks inherent in removing them from school. Recommendations for educators and policy-makers are presented to assist educators in preventing expulsion and improving educational and socio-emotional outcomes for expelled students.

This paper studies the narrative stained glass cycle of the Life of Saint Mary the Egyptian at Bourges Cathedral within the context of prevailing—and often conflicting--civil and ecclesiastical attitudes toward sex, sexual sin, and prostitution in early thirteenth century France. Although the Church maintained that sexual sin was mortal sin, civil records suggest the public was skeptical. Through the example of a penitent harlot, this window, both structurally and in thematic content, attempts to map a doctrinally appropriate path from sexual sin to purity of spirit—and salvation—through complete submission to the Church and its clergy.

This study examines how Native American warriors imprisoned at Fort Marion in St. Augustine, Florida, between 1875 and 1878, used their drawings to perform acculturation. I use the Kiowa warrior Paul Caryl Zotom’s drawings as a case study to demonstrate how the prisoners became methodical and formulaic in their subject matter and artistic style. Euro-American visitors to Fort Marion appreciated particular drawings over others, thereby directing subject matter. Prisoners adopted European artistic standards, thus, connected with their White audience further. Zotom’s embrace of both the subject matter and artistic style that the Euro-American audience appreciated most indicates his desire to demonstrate how successful he and his fellow prisoners were at adopting the white man’s road. I argue that much of the apparent change displayed visually in Zotom’s drawings was performed rather than true acculturation.

Howard University was recently identified as a school that lacks recycling initiatives and policies. In response, Howard University drafted a plan to become the greenest college in the United States. This study was conducted to identify if there were existing recycling practices on the campus, compare the practices, if applicable, to the local recycling regulations, and present potential obstacles and recommendations to be used by Howard University while designing their recycling program. This study was performed by visiting the campus to identify recycling practices and interviewing campus occupants, and comparing the findings to the local recycling regulations. The key finding of this study is that Howard University does not have a recycling program and does not comply with local recycling regulations.

Bio-fuels such as ethanol provide an extraordinary opportunity to address our dependency on foreign oil. This case study examines the economic and environmental impacts associated with constructing and operating a dry mill ethanol manufacturing facility in a Southwest Georgia town and surrounding communities. The case study found that the plant had little impact on air quality, water quality, and habitat fragmentation. However, economic results showed the plant produced $1.5 million in tax revenues, and 86 jobs. Ethanol producers and communities must consider both the economic and environmental impacts on a local community when searching or attracting a bio-fuels plant. Likewise, communities should be aware of these challenges when attracting ethanol production plants.

The Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) of 1980, and the Superfund Amendments and Reauthorization Act (SARA) of 1986 strengthen roles of the community in the CERCLA process. Many layers of bureaucracy and the complexity of regulations make the implementation and enforcement of environmental policy a burdensome process. Local government, the public and private corporations have a critical role in the CERCLA decision-making process by implementing a comprehensive public participation process. This paper examines a case study in which a local Colorado health department implemented a successful public participation process in order to positively affect the remediation decision-making process.

Renewable energy such as biomass has given markets, including dairy farms, an effective approach to reducing the costs of sustaining a profitable business. Anaerobic digestion systems offer dairy farms a very effective way to reduce manure odor, comply with soil and water pollution regulations, manufacture compost for general market sales, produce irrigation capacity and generate on-site electricity as well as the ability to sell excess electricity back to the local utilities. This project defines anaerobic digestion technologies and practices, analyzes case studies and presents a step-by-step anaerobic digestion project startup checklist. The result is an anaerobic digestion project working guide that acts as a tool to aid dairy farmers in their own potential anaerobic digestion project.

Microgrids are autonomously operated, geographically clustered electricity generation and distribution systems that supply power in closed system settings; they are highly compatible with renewable energy sources and distributed generation technologies. Mocrogrids are currently a serially underutilized and underappreciated commodity in the energy infrastructure portfolio worldwide. To demonstrate feasibility under poor conditions (little renewable energy potential and high demand) this capstone project develops a theoretical case study in which a renewable microgrid is employed to power rural communities of southern Montgomery County, Arkansas. Utilizing commercially manufactured 1.5-megawatt wind turbines and a 1-megawatt solar panel generation system, 4-megawatts of lithium ion battery storage, and demand response technology, a microgrid is designed that supplies 235 households with reliable electricity supply.
