Description
The high rate of teacher turnover in the United States has prompted a number of studies into why teachers leave as well as why they stay. The present study aims to add to that knowledge specifically regarding why teachers choose to stay at urban schools. Several reasons teachers in general choose to stay have been identified in previous studies including faith in their students, continuing hope and sense of responsibility, and love among others. The importance of such a study is the possibility of designing programs that reinforce teacher success through understanding the personal and professional reasons teachers choose to stay. Getting teachers to stay is important to the nation's goal of providing equity in science education to all children. Important to this research is an understanding of motivational theories. Already a challenge in the over-busy modern world, the ability to self-motivate and motivate others is of particular importance to teachers in urban schools as well as teachers struggling against restrictive budgets. Studies have shown teachers extrinsically motivated will need external rewards to encourage them while teachers who are intrinsically motivated will have their own internal reasons such as satisfaction in contributing to the future, self-actualization, or the joy of accomplishment. Some studies have suggested that teachers who decide to remain teaching tend to be intrinsic motivators. Unfortunately, the environment in most Western country educational systems presents a challenge to achieving these intrinsic goals. As a result, self-determination theory should play a significant role in shaping educational programs. The following study examined the perspectives of secondary school science teachers, specifically regarding why they opted to remain within the classroom in urban districts. It was conducted utilizing interviews and surveys of teachers working within urban school districts in Arizona and California. The sample consisted of 94 science teachers. More than half of the participants were White females and 36 percent of them had been teaching for more than 15 years. Participation in the study was based on self-selected volunteerism. Survey questions were based on self-determination theory and used Likert scale responses. Follow-up audiotaped interview requested information regarding identity and their social interaction within the urban settings. The survey responses were analyzed using SPSS for descriptive statistics, one-way ANOVA, and linear regression. The results of this study provide insight on what works to motivate science teachers to continue teaching in less than ideal school settings and with such high bureaucratic impediments as standardized testing and school rating systems. It demonstrates that science teachers do seem to be intrinsically motivated and suggests some areas in which this motivation can be fostered. Such results could help in the development of teacher support groups, professional development programs, or other programs designed to assist teachers struggling to deal with the specific problems and needs of inner city school students.

Description
The craft of improvisation at the organ has survived a long period of dormancy and is experiencing a strong resurgence in the twenty-first century. This project seeks to establish a precedence for the value of notated music as a resource in learning improvisation, and then, through music analysis, provide examples of how that process can develop. The result of the ideas presented here is a pathway whereby any disciplined organist can learn to imitate composed music, assimilate the musical ideas, and innovate through the act of spontaneous improvisation.

Description
Calcium hydroxide carbonation processes were studied to investigate the potential for abiotic soil improvement. Different mixtures of common soil constituents such as sand, clay, and granite were mixed with a calcium hydroxide slurry and carbonated at approximately 860 psi. While the carbonation was successful and calcite formation was strong on sample exteriors, a 4 mm passivating boundary layer effect was observed, impeding the carbonation process at the center. XRD analysis was used to characterize the extent of carbonation, indicating extremely poor carbonation and therefore CO2 penetration inside the visible boundary. The depth of the passivating layer was found to be independent of both time and choice of aggregate. Less than adequate strength was developed in carbonated trials due to formation of small, weakly-connected crystals, shown with SEM analysis. Additional research, especially in situ analysis with thermogravimetric analysis would be useful to determine the causation of poor carbonation performance. This technology has great potential to substitute for certain Portland cement applications if these issues can be addressed.

Description
As green buildings become more popular, the challenge of structural engineer is to move beyond simply green to develop sustainable, and high-performing buildings that are more than just environmentally friendly. For decades, Portland cement-based products have been known as the most commonly used construction materials in the world, and as a result, cement production is a significant source of global carbon dioxide (CO2) emissions, and environmental impacts at all stages of the process. In recent years, the increasing cost of energy and resource supplies, and concerns related to greenhouse gas emissions and environmental impacts have ignited more interests in utilizing waste and by-product materials as the primary ingredient to replace ordinary Portland cement in concrete systems. The environmental benefits of cement replacement are enormous, including the diversion of non-recycled waste from landfills for useful applications, the reduction in non-renewable energy consumption for cement production, and the corresponding emission of greenhouse gases. In the vast available body of literature, concretes consisting activated fly ash or slag as the binder have been shown to have high compressive strengths, and resistance to fire and chemical attack. This research focuses to utilize fly ash, by-product of coal fired power plant along with different alkaline solutions to form a final product with comparable properties to or superior than those of ordinary Portland cement concrete. Fly ash mortars using different concentration of sodium hydroxide and waterglass were dry and moist cured at different temperatures prior subjecting to uniaxial compressive loading condition. Since moist curing continuously supplies water for the hydration process of activated fly ash mortars while preventing thermal shrinkage and cracking, the samples were more durable and demonstrated a noticeably higher compressive strength. The influence of the concentration of the activating agent (4, or 8 M sodium hydroxide solution), and activator-to-binder ratio of 0.40 on the compressive strengths of concretes containing Class F fly ash as the sole binder is analyzed. Furthermore, liquid sodium silicate (waterglass) with silica modulus of 1.0 and 2.0 along with activator-to-binder ratio of 0.04 and 0.07 was also studied to understand its performance in contributing to the strength development of the activated fly ash concrete. Statistical analysis of the compressive strength results show that the available alkali concentration has a larger influence on the compressive strengths of activated concretes made using fly ash than the influence of curing parameters (elevated temperatures, condition, and duration).

Description
This research paper creates a modern score transcription of selected choral works by composer Alexander Chesnokov. The life and works of Alexander Chesnokov are almost completely unknown in the United States. A collection of his works is housed in the New York Public Library (NYPL). Selected transcripts from this collection provide insight into the works and style of Alexander Chesnokov. They may also serve as a study guide and point for further research and explorations into the life and compositions of this Russian composer. The sets of transcriptions within this paper were created from a microfilm copy from the NYPL's archival holdings. This study comprises transcriptions of selected scores, a discussion of errors and editorial choices, text translations, and a brief history of choral performance and style during pre-revolutionary Russia, the time period during which this composer lived and wrote.

Description
From Marathon to Athens was inspired by the legend of Pheidippides, a Greek messenger who ran approximately twenty-six miles between the cities of Marathon and Athens in ancient Greece to deliver an important wartime message. According to the legend, he died shortly after completing the journey. The marathon races of today were inspired by his story, though it may be more myth than reality. There is a great deal of inherent drama in the undertaking of such a feat, whether it be a marathon or any other test of strength and endurance. There is the rush of adrenaline when it begins, followed by the excitement and exhilaration of the first few miles. Then, there is a period of settling in and finding a groove - when the runner realizes that there is a long way to go, but is determined to pace him or herself and stay strong. All too often, there is the "wall" that appears about three-quarters of the way through, when it seems that there is no strength left to finish the race. Finally, there is the final push to the finish line - where the runner decides that they are going to make it, in spite of fatigue, pain, or any other obstacle. In this piece, I used a simple melody that was very loosely modeled after a melody from ancient Greece (the tune inscribed on the Epitaph of Seikilos). I used both Phrygian and Dorian modes, which, according to Plato, were most appropriate for soldiers. Throughout the piece, I used different instruments, mostly percussion, to represent the heartbeat of the runner. In the legend, the runner dies - in the piece, the heartbeat becomes very fast and then rather erratic. It then slows and, finally, stops. Though I find the story of Pheidippides inspiring, I wish all marathon runners and athletes of every kind (myself included) a safer and happier outcome!

Description
The Burning Man Festival, a free-spirited yet highly sophisticated social experiment celebrating "radical self expression and radical self reliance" is well-known for its large-scale and highly interactive public art installations. For twenty-five years, Burners (as festival participants are called) have been creating and displaying amazing works of art for the annual event, which currently takes place in Nevada's Black Rock Desert. In the desert, Burners build a temporary city, appropriate the open space to serve as their "tabula rasa" or "blank canvas," and unleash their creative potential in the name of "active participation" and social civility. In the process, they produce public art on a scale unprecedented in United States history. This dissertation, a visual and narrative ethnography, explores the layers of aesthetic and social meanings Burners associate with public art. Told in narrative form, this project utilizes "in situ" field notes, photographic field notes, rhetorical analyses of art installations, thematic analysis of Burner storytelling, and writing as a method of inquiry as means for investigating and understanding more fully the ways Burners create, display, and consume public art. Findings for this project indicate Burners value public art beyond its material presentation. Preparing for, building, celebrating, and experiencing aesthetic transformation through the engagement of public art all are viewed as valuable"art" experiences at Burning Man. Working in tandem, these experiences also produce profound feelings of connection and collaboration in the community, suggesting Burning Man's methods for producing public art could serve as model to follow, or points for reflection, for other groups wishing to use public art and other forms of material expression to bring their members closer together.

Description
Families and schools share the monumental responsibility of educating children. Children and parent-teacher conferences remain the primary means by which parents and teachers share academic information. Given the limited effectiveness of these conferences, a more compelling alternative for home-school collaboration on academic matters is warranted. The purpose of this action research study was to examine an alternative approach to parent-teacher conferences, Academic Parent Teacher Teams (APTT). APTT is a classroom-based parent involvement model composed of three 75-minute parent-teacher team meetings and an individual 30-minute parent-teacher session. Team meetings are highly structured and include six components: personally inviting parents by the teacher; sharing whole-class and individual student data; setting 60-day academic goals; coaching parents in `teaching' skills; distributing take-home practice materials; and networking. Quantitative data included pre- and post-intervention parent surveys, and pre- and post-intervention student scores on high frequency words and oral reading fluency. Qualitative data included field notes from APTT meetings, pre- and post-intervention teacher reflections, and teacher, parent, and student interviews. Findings from this study supported previous research that suggested most parents have high aspirations for their children's academic success. Findings also indicated parents understood their involvement was important to support academic growth. Increased quality and quantity of parent-teacher communication and interaction improved parents' ability to support student learning at home. Parents increased involvement in children's academics was related to teachers' provision of detailed information and training of parents. Qualitative results showed parents' teaching efforts contributed to students' improvement in reading. To understand this outcome, effectual congruence (EC) was offered as an explanation. EC occurred when parents and teachers agreed on an action plan for student achievement, when there was a mutual commitment to taking specific actions and when each person's role was clearly defined and implemented. EC became the process that supported achievement growth. These results demonstrated that relationships between parents and teachers are complex. Further, when teachers and parents were fully invested in collaboration it produced powerful results for students. This study provided critical information for parents, teachers, administrators and policy makers attempting to implement more effective parent involvement initiatives.
