Description
This dissertation explores the history of ancestral rituals and the related political controversy in the Song China (960-1279). Considering the pivotal role played by ancestral rites in shaping Chinese identity and consciousness, this study contributes to a better understanding of how ancestral ritual has been politicized in Chinese history as a specific cultural apparatus to manipulate politics through theatrical performance and liturgical discussion. Through a contextual analysis of a variety of Song scholar-officials and their ritual writings, including memorials, private letters, and commentaries on the ritual Classics, this study demonstrates that Song ritual debates over the zhaomu 昭穆 sequence--that is, the positioning of ancestral temples and spirit tablets in ancestral temples with preparation for alternation or removal--differentiated scholar-officials into separate factions of revivalists, conventionalists and centrists. From a new perspective of ritual politics, this study reveals the discursiveness of the New Learning (xinxue新學) community and its profound influence on the Learning of the Way (Daoxue 道學) fellowship of the Southern Song (1127-1279). It examines the evolution of the New Learning fellowship as a dynamic process that involved internal tension and differentiation. Daoxue ritualism was a continuation of this process in partaking in the revivalist approach of ritual that was initiated by the New Learning circle. Nowadays, the proliferation of ritual and Classical studies crystallizes the revitalization of Confucianism and Confucian rituals in China. Taking zhaomu as a point of departure, this project provides a lens through which modern scholars can explore the persistent tension between knowledge and power by rethinking the modernization of ritual and ritual politics in contemporary China.

Description
Bacteria of the Legionella genus are a water-borne pathogen of increasing concern due to being responsible for more annual drinking water related disease outbreaks in the United States than all other microbes combined. Unfortunately, the development of public health policies concerning Legionella has impeded by several key factors, including a paucity of data on their interactions and growth requirements in water distribution networks, a poor understanding of potential transmission sources for legionellosis, and limitations in current methodology for the characterization of these pathogens. To address these issues, a variety of research approaches were taken. By measuring Legionella survival in tap water, association in pipe material biofilms, population dynamics in a model distribution system, and occurrence in drinking water distribution system biofilms, key aspects of Legionella ecology in drinking water systems were revealed. Through a series of experiments qualitatively and quantitatively examining the growth of Legionella via nutrients obtained from several water sources, environmental nutritional requirements and capability for growth in the absence of host organisms were demonstrated. An examination of automobile windshield washer fluid as a possible source of legionellosis transmission revealed Legionella survival in certain windshield washer fluids, growth within washer fluid reservoirs, high levels and frequency of contamination in washer fluid reservoirs, and the presence of viable cells in washer fluid spray, suggesting the potential for exposure to Legionella from this novel source. After performing a systematic and quantitative analysis of methodology optimization for the analysis of Legionella cells via matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, several strains of this microbe isolated from separated and varied environmental water sampling sites were distinctly typed, demonstrating a potential application of this technology for the characterization of Legionella. The results from this study provide novel insight and methodology relevant to the development of programs for the monitoring and treatment of Legionella in drinking water systems.

Description
East Asia in the aftermath of the Cold War might provide the most favorable case for realist theory due to historical rivalries, territorial disputes, economic competition, great power politics and deep-rooted realist beliefs among politicians in the region. Yet the fundamental realist prediction of balance of power in the region has not materialized. Neither internal nor external balancing in their original senses is explicitly present. This poses a serious challenge to realism and more broadly, western international relations theories for understanding regional dynamics. Several explanations have been put forward in previous research, such as a total rejection of the applicability of realism for explaining East Asian politics, modifying realism by adding new variables, and focusing on domestic variables. Using a neoclassical realist term, underbalancing, this dissertation goes beyond neoclassical realist theory of underbalancing by reintroducing the distinction between external and internal balancing, which has direct implications for the resources needed for a balancing policy and external reactions to balancing policy. In particular, this approach emphasizes the effect of interaction between states on underbalancing. By doing so, it also highlights what is omitted by realism, namely, the agency of the targeted state at risk of being balanced. In other words, the policy of the state that is aware of its risk of being balanced could draw upon foreign policy tools it possesses to neutralize the balancing efforts from others. This notion of state policies influencing the outcome of balance of power is tested with post-Cold War East Asian politics. The cases included China-Japan and China-ASEAN strategic interactions after the Cold War. Based on materials from public media outlets, official documents and recently leaked U.S. diplomatic cables, this dissertation argues that China's policies towards neighboring states- policies expressed variously through cultural, diplomatic, economic and security initiatives- are indispensable to explain the fact of underbalancing in the region.

Description
Granular activated carbon (GAC) filters are final polishing step in the drinking water treatment systems for removal of dissolved organic carbon fractions. Generally filters are colonized by bacterial communities and their activity reduces biodegradable solutes allowing partial regeneration of GAC's adsorptive capacity. When the bacteria pass into the filtrate due to increased growth, microbiological quality of drinking water is compromised and regrowth in the distribution system occurs. Bacteria attached to carbon particles as biofilms or in conjugation with other bacteria were observed to be highly resistant to post filtration microbial mitigation techniques. Some of these bacteria were identified as pathogenic.
This study focuses on one such pathogen Legionella pneumophila which is resistant to environmental stressors and treatment conditions. It is also responsible for Legionnaires' disease outbreak through drinking water thus attracting attention of regulatory agencies. The work assessed the attachment and colonization of Legionella and heterotrophic bacteria in lab scale GAC media column filters. Quantification of Legionella and HPC in the influent, effluent, column's biofilms and on the GAC particles was performed over time using fluorescent microscopy and culture based techniques.
The results indicated gradual increase in the colonization of the GAC particles with HPC bacteria. Initially high number of Legionella cells were detected in the column effluent and were not detected on GAC suggesting low attachment of the cells to the particles potentially due to lack of any previous biofilms. With the initial colonization of the filter media by other bacteria the number of Legionella cells on the GAC particles and biofilms also increased. Presence of Legionella was confirmed in all the samples collected from the columns spiked with Legionella. Significant increase in the Legionella was observed in column's inner surface biofilm (0.25 logs up to 0.52 logs) and on GAC particles (0.42 logs up to 0.63 logs) after 2 months. Legionella and HPC attached to column's biofilm were higher than that on GAC particles indicating the strong association with biofilms. The bacterial concentration slowly increased in the effluent. This may be due to column's wall effect decreasing filter efficiency, possible exhaustion of GAC capacity over time and potential bacterial growth.

Description
Research in microbial biofuels has dramatically increased over the last decade. The bulk of this research has focused on increasing the production yields of cyanobacteria and algal cells and improving extraction processes. However, there has been little to no research on the potential impact of viruses on the yields of these phototrophic microbes for biofuel production. Viruses have the potential to significantly reduce microbial populations and limit their growth rates. It is therefore important to understand how viruses affect phototrophic microbes and the prevalence of these viruses in the environment. For this study, phototrophic microbes were grown in glass bioreactors, under continuous light and aeration. Detection and quantification of viruses of both environmental and laboratory microbial strains were measured through the use of a plaque assay. Plates were incubated at 25º C under continuous direct florescent light. Several environmental samples were taken from Tempe Town Lake (Tempe, AZ) and all the samples tested positive for viruses. Virus free phototrophic microbes were obtained from plaque assay plates by using a sterile loop to scoop up a virus free portion of the microbial lawn and transferred into a new bioreactor. Isolated cells were confirmed virus free through subsequent plaque assays. Viruses were detected from the bench scale bioreactors of Cyanobacteria Synechocystis PCC 6803 and the environmental samples. Viruses were consistently present through subsequent passage in fresh cultures; demonstrating viral contamination can be a chronic problem. In addition TEM was performed to examine presence or viral attachment to cyanobacterial cells and to characterize viral particles morphology. Electron micrographs obtained confirmed viral attachment and that the viruses detected were all of a similar size and shape. Particle sizes were measured to be approximately 50-60 nm. Cell reduction was observed as a decrease in optical density, with a transition from a dark green to a yellow green color for the cultures. Phototrophic microbial viruses were demonstrated to persist in the natural environment and to cause a reduction in algal populations in the bioreactors. Therefore it is likely that viruses could have a significant impact on microbial biofuel production by limiting the yields of production ponds.

Description
This study was devised to elucidate key information concerning the potential risk posed by Legionella in reclaimed water. A series of biological experiments and a recharge basin soil column study were conducted to examine the survival, growth, and transport of L. pneumophila through engineered reclaimed water systems. A pilot-scale, column study was set up to measure Legionella transport in the columns under Arizona recharge basin conditions. Two columns, A and B, were packed to a depth of 122 cm with a loamy sand media collected from a recharge basin in Mesa, Arizona. The grain size distribution of Column A differed from that of Column B by the removal of fines passing the #200 sieve. The different soil profiles represented by column A and B allowed for further investigation of soil attributes which influence the microbial transport mechanism. Both clear PVC columns stand at a height of 1.83 m with an inner diameter of 6.35 cm. Sampling ports were drilled into the column at the soil depths 15, 30, 60, 92, 122 cm. Both columns were acclimated with tertiary treated waste water and set to a flow rate of approximately 1.5 m/d. The columns were used to assess the transport of a bacterial indicator, E. coli, in addition to assessing the study's primary pathogen of concern, Legionella. Approximately, 〖10〗^7 to 〖10〗^9 E. coli cells or 〖10〗^6 to 〖10〗^7Legionella cells were spiked into the columns' head waters for each experiment. Periodically, samples were collected from each column's sampling ports, until a minimum of three pore volume passed through the columns.
The pilot-scale, column study produced novel results which demonstrated the mechanism for Legionella to be transported through recharge basin soil. E. coli was transported, through 122 cm of the media in under 6 hours, whereas, Legionella was transported, through the same distance, in under 30 hours. Legionella has been shown to survive in low nutrient conditions for over a year. Given the novel results of this proof of concept study, a claim can be made for the transport of Legionella into groundwater aquifers through engineering recharge basin conditions, in Central Arizona.

Description
This dissertation project addresses one of the most critical problems in the study of religion: how new formations of religion are constructed and constituted. My work builds on the recent revisions of the secularization theory, which demonstrates the alternative and hybrid ways people seek out religion in modernity. To this end, my project examines the emerging popularity and phenomenon of international meditation centers in Thailand, focusing on encounters between international meditation center teachers and their international students. Through participant observation and in-depth interviews at these sites throughout Thailand, my project explores the social processes of religious change and adaptation, and the construction of religious meaning. I detail the historical conditions that led to the formation of persisting ideas of Buddhism by tracing the continuities between Orientalist interpretations and modern-day spiritual seekers. My work contributes to a greater understanding of the most recent articulation of this engagement and interaction between Buddhism and the international community and adds to the burgeoning scholarship that reconsiders the relationship between religion and modernity. I investigate this relationship in regard to international meditation centers in Thailand through three angles: promotional materials concerning meditation in Thailand, experiences of international meditators, and teachings of international meditation center teachers. I contextualize this ethnographic analysis with an evaluation of the relationship of Buddhism to discourses of modernity and Orientalism as well as a historical inquiry into the rise of lay meditation in Thailand. Throughout I argue that international meditators' engagement with meditation in Thai temples constitutes a hybrid religiosity where the decontextualized practice of meditation is mixed with both non-religious and other religious beliefs and practices. Social discourses and practices involving meditation, even in a Buddhist country, demonstrate the deconstruction of traditional religiosity in modernity and the rise of hybrid religiosity. Through the decontextualization of meditation and the discourse of the practice having no religious boundaries, meditation becomes mixed with tourism, therapy, healing, as well as other religious and secular practices. This research contributes to studies of Theravada Buddhism as well as modern, global religions and the contemporary intersection between religion and tourism.

Description
This dissertation seeks to theorize small state strategic culture with special reference to the attitude of the ASEAN states toward institutionalizing regional cooperative security architectures. The quantitative case studies show that in small states where historically rooted strategic preferences may be limited, material influences and situational considerations take precedence over ideational factors in the making of the state's strategic culture. Second, the content of small state strategic culture focuses primarily on foreign and security policy issues that originate in their neighborhood. Lastly, Small states' threat perceptions from the neighborhood over time dictate the formation of strategic culture (provocative vs. cooperative). The qualitative case studies demonstrate that small Southeast Asian states (Singapore, Thailand, and Malaysia) exhibit a higher tendency for conflict. Multilateral cooperation is at best selective. Bilateral means is still the preferred policy approach when dealing with other states. This dissertation concludes with a pessimistic remark on the prospects for the development and maturation of the ASEAN Political-Security Community. At its current stage, the APSC appears to be a policy instrument created only to reinforce ASEAN's centrality in charting the region's security architecture. This is no small accomplishment in itself nonetheless.

Indian gaming casinos are now a common sight around Arizona. The study of the history of the Arizona Indian Gaming establishments is the topic of my thesis which focuses on the conflicts in 1992, between J. Fife Symington, governor of the State of Arizona, and the Arizona Indian tribes, particularly the Fort McDowell Yavapai Indian Community. In order to learn more about this small band of Yavapai, my thesis examines the early history of the Yavapai and some of its remarkable leaders, along with the history of Indian Tribal gaming in America and Arizona following the blockade by the Yavapai. My thesis examines how the Modern Political Economy Theory (MPET) framed Yavapai survival and identity along with their determination to achieve economic self-sufficiency. My research extended into use the legal court system the by American Indian Tribes to achieve their economic goals, that culminating in the Supreme Court ruling in California v. Cabazon Band of Mission Indians (1987) confirming the rights of Indian tribes to conduct gaming on tribal reservation lands. Congress followed with the "Indian Gaming Regulatory Act" of 1988, (IGRA) to regulate the conduct of gaming on Indian lands, including the stipulation that states negotiate in good faith with the state's Indian tribes. Arizona Governor Symington refused to negotiate the necessary compacts between the State of Arizona and the Arizona Indian tribes. The dispute reached a climax on May 12, 1992, when Attorney General of the U.S., Linda A. Akers, ordered a raid on Arizona Indian gaming casinos and the Fort McDowell Yavapai countered with a blockade to prevent the removal of their gaming machines. The result of this action by the Yavapai blockade opened compact negotiations between Governor Symington and the Arizona Indian tribes. This resulted in the growth in tribal gaming casinos along with increased political and economic influence for the Arizona Indian tribes. My conclusion explains the current state of the Fort McDowell Yavapai Indian Nation and describes the benefits from Indian casino gaming in the greater Phoenix area.

Nanotechnology is a scientific field that has recently expanded due to its applications in pharmaceutical and personal care products, industry and agriculture. As result of this unprecedented growth, nanoparticles (NPs) have become a significant environmental contaminant, with potential to impact various forms of life in environment. Metal nanoparticles (mNPs) exhibit unique properties such as increased chemical reactivity due to high specific surface area to volume ratios. Bacteria play a major role in many natural and engineered biogeochemical reactions in wastewater treatment plants and other environmental compartments. I have evaluated the laboratory isolates of E. coli, Bacillus, Alcaligenes, Pseudomonas; wastewater isolates of E. coli and Bacillus; and pathogenic isolate of E. coli for their response to 50 & 100 nm sized Cu nanoparticles (CuNPs). Bactericidal tests, scanning electron microscopy (SEM) analyses, and probable toxicity pathways assays were performed. The results indicate that under continuous mixing conditions, CuNPs are effective in inactivation of the selected bacterial isolates. In general, exposure to CuNPs resulted in 4 to >6 log reduction in bacterial population within 2 hours. Based on the GR, LDH and MTT assays, bacterial cells showed different toxicity elicitation pathways after exposure to CuNPs. Therefore, it can be concluded that the laboratory isolates are good candidates for predicting the behavior of environmental isolates exposed to CuNPs. Also, high inactivation values recorded in this study suggest that the presence of CuNPs in different environmental compartments may have an impact on pollutants attenuation and wastewater biological treatment processes. These results point towards the need for an in depth investigation of the impact of NPs on the biological processes; and long-term effect of high load of NPs on the stability of aquatic and terrestrial ecologies.
