Understanding and Management of Holistic Water Quality and Legionella in Public Building Systems

This research aims to develop an understanding of how interventions designed to improve water quality in buildings can be used to mitigate Legionella pneumophila concentrations. Intervention methods can be described as any approach that can be used to improve microbial water quality. In order to provide a foundation of background knowledge, a literature review was conducted to identify similar studies and collect relevant and timely research similar to the subject. The information gathered from the literature review was used to structure the sampling process and parameters. Using the research collected from the literature review, a review table was created to summarize the differences in the studies conducted and to determine research gaps. To categorize the studies, intervention methods, contaminants addressed, and water quality meta-data were differentiated for each of the articles. For the purpose of the sampling process, the three interventions analyzed consist of flushing, water heater set point change, and both flushing and water heater set point change. The locations of the sampling consisted of the city drinking water inlet, the basement janitor's closet, basement shower, 2nd floor, 3rd floor, and 7th floor break rooms and restrooms of the Interdisciplinary Science and Technology Building IV at ASU. For the flushing intervention, the sampling results demonstrated an increase in free and total chlorine concentration post flushing which aligns with the research found in the literature review. In addition, it was observed that iron concentrations drastically increased for both the cold and hot water by flushing. There was a significant decrease detected for ATP concentrations post flush in the hot line. However through the sampling session, the flushing intervention did not yield statistically significant results for Legionella concentrations.

Every body holds a story: empowerment through social-somatics and community dance within a K-12 dance education program

Every body holds a story. Those stories are rich with physical movements to be expressed, and through the physical expression comes self-awareness and transformation. A partnership between Arizona State University and Arcadia High School was the vehicle in which I implemented a curriculum built around somatic experiences and communal beliefs and values. The framework for this investigated curriculum teaches students' embodiment of self, tolerance and acceptance in collaboration, life skills through applied constructivist principles, and increased critical thinking and problem-solving abilities. This research involved somatic exercises enabling participants to have insight into natural moving patterns, how such patterns relate to others and outside environments. Research concluded with collective dialogue around individual and shared experiences. I worked twice per week with a choreography class with a four unit curriculum. From varying modes of assessment (e.g., one-on-one interviews, group discussions, journals, surveys, ongoing observations) students' responses to this type of curriculum ranged from excitement and curiosity to frustrating and provoking. Although these areas of research are not necessarily new to the field of dance and education, gaps in dialogue, published work, and reliable resources prove these theories and methods are still valued and necessary. This research demonstrates the imperative demand in dance education for deeper connections of self-discovery.

In contemporary U.S. culture, dance is often confined to the young and the trained, isolated on stages and in dance studios, and viewed as entertainment that is disconnected from "real life." Socially engaged dance practices re-connect dance to society in meaningful ways. By connecting individuals to their own bodies, to each other, to ideas, and to social, civic, and educational institutions, socially engaged dance practices use movement, the body, and the tools of participatory art, which contributes to the development of a democratic society, while catalyzing social change, and building healthy communities.
