abstract: The purpose of this study was to increase first year residential student engagement and participation in residence hall programs during the 2011 fall semester at the Downtown Phoenix Campus of Arizona State University. Six upperclassmen (Taylor Place Leaders) residing in a residence hall (Taylor Place) were matched by academic major with 17 first year students residing in Taylor Place. During the first eleven weeks of the fall semester 2011, first year students met regularly with their Taylor Place Leader to discuss residence hall program participation, living in Taylor Place, attending Arizona State University, and adjusting to their academic responsibilities. All 23 program participants completed a pre-survey inquiring about their satisfaction with their decision to attend Arizona State University, residence hall involvement, and knowledge of university services. The researcher met with Taylor Place Leaders throughout the study to learn about their experiences with mentoring the first year students. At the conclusion of the study, participants met with the researcher to complete a post-survey inquiring about the same information as the pre-survey and participated in individual interviews discussing their experience in the study. Two major findings were identified. First, participants reported that the Taylor Place Experience peer mentoring program assisted first year students in adjusting to college through identifying student support resources. Second, participants reported that living on campus during the freshman year, with mentoring support, could promote academic success, compared with living at home due to the close living proximity of their peers. Taylor Place also saw an increase in residence hall program participation during the 2011 fall semester in comparison to the 2010 fall semester. However, six of the seventeen freshman study participants decided to move out of Taylor Place and live at home by the end of the 2011 fall semester, for various reasons, such as family and employment obligations as well as being homesick. / Dissertation/Thesis / Ed.D.

The integration of cogeneration technologies in residential communities has the potential of reducing energy demand and harmful emissions. This study investigated the impact of selected design parameters on the environmental and economic performances of cogeneration systems integrated into residential communities in cold U.S. climates following a centralized or a decentralized integration approach. Parameters investigated include: 1) density, 2) use mix, 3) street configuration, 4) housing typology, 5) envelope and building systems' efficiencies, 6) renewable energy utilization, 7) cogeneration system type, 8) size, and 9) operation strategy. Based on this, combinations of design characteristics achieving an optimum system performance were identified. The study followed a two-phased mixed research model: first, studies of residential community design and three case studies of sustainable residential communities were analyzed to identify key design parameters; subsequently, simulation tools were utilized to assess the impact of each parameter on cogeneration system performance and to optimize the community design to improve that performance. Assessment procedures included: developing a base-line model representing typical design characteristics of U.S. residential communities; assessing the system performance within this model, for each integration approach, using three performance indicators: reduction in primary energy use, reduction in CO2 emissions; and internal rate of return; assessing the impact of each parameter on the system performance through developing 46 design variations of the base-line model representing changes in these parameters and calculating the three indicators for each variation; using a multi-attribute decision analysis methodology to evaluate the relative impact of each parameter on the system performance; and finally, developing two design optimization scenarios for each integration approach. Results show that, through design optimization, existing cogeneration technologies can be economically feasible and cause reductions of up to 18% in primary energy use and up to 42% in CO2 emissions, with the centralized approach offering a higher potential for performance improvements. A significant correlation also existed between design characteristics identified as favorable for cogeneration system performance and those of sustainable residential communities. These include high densities, high mix of uses, interconnected street networks, and mixing of housing typologies. This indicates the higher potential for integrating cogeneration systems in sustainable residential communities.
