Description
The Hohokam of central Arizona left behind evidence of a culture markedly different from and more complex than the small communities of O'odham farmers first encountered by Europeans in the sixteenth and seventeenth centuries A.D. Archaeologists have worked for well over a century to document Hohokam culture history, but much about Pre-Columbian life in the Sonoran Desert remains poorly understood. In particular, the organization of the Hohokam economy in the Phoenix Basin has been an elusive and complicated subject, despite having been the focus of much previous research. This dissertation provides an assessment of several working hypotheses regarding the organization and evolution of the pottery distribution sector of the Hohokam economy. This was accomplished using an agent-based modeling methodology known as pattern-oriented modeling. The objective of the research was to first identify a variety of economic models that may explain patterns of artifact distribution in the archaeological record. Those models were abstract representations of the real-world system theoretically drawn from different sources, including microeconomics, mathematics (network/graph theory), and economic anthropology. Next, the effort was turned toward implementing those hypotheses as agent-based models, and finally assessing whether or not any of the models were consistent with Hohokam ceramic datasets. The project's pattern-oriented modeling methodology led to the discard of several hypotheses, narrowing the range of plausible models of the organization of the Hohokam economy. The results suggest that for much of the Hohokam sequence a market-based system, perhaps structured around workshop procurement and shopkeeper merchandise, provided the means of distributing pottery from specialist producers to widely distributed consumers. Perhaps unsurprisingly, the results of this project are broadly consistent with earlier researchers' interpretations that the structure of the Hohokam economy evolved through time, growing more complex throughout the Preclassic, and undergoing a major reorganization resulting in a less complicated system at the transition to the Classic Period.

Description
Energy is a central concern of sustainability because how we produce and consume energy affects society, economy, and the environment. Sustainability scientists are interested in energy transitions away from fossil fuels because they are nonrenewable, increasingly expensive, have adverse health effects, and may be the main driver of climate change. They see an opportunity for developing countries to avoid the negative consequences fossil-fuel-based energy systems, and also to increase resilience, by leap-frogging-over the centralized energy grid systems that dominate the developed world. Energy transitions pose both challenges and opportunities. Obstacles to transitions include 1) an existing, centralized, complex energy-grid system, whose function is invisible to most users, 2) coordination and collective-action problems that are path dependent, and 3) difficulty in scaling up RE technologies. Because energy transitions rely on technological and social innovations, I am interested in how institutional factors can be leveraged to surmount these obstacles. The overarching question that underlies my research is: What constellation of institutional, biophysical, and social factors are essential for an energy transition? My objective is to derive a set of "design principles," that I term institutional drivers, for energy transitions analogous to Ostrom's institutional design principles. My dissertation research will analyze energy transitions using two approaches: applying the Institutional Analysis and Development Framework and a comparative case study analysis comprised of both primary and secondary sources. This dissertation includes: 1) an analysis of the world's energy portfolio; 2) a case study analysis of five countries; 3) a description of the institutional factors likely to promote a transition to renewable-energy use; and 4) an in-depth case study of Thailand's progress in replacing nonrenewable energy sources with renewable energy sources. My research will contribute to our understanding of how energy transitions at different scales can be accomplished in developing countries and what it takes for innovation to spread in a society.

Description
In this dissertation I argue that medieval peoples used a different style of identity from those applied to them by later scholarship and question the relevance of applying modern terms for identity groups (e.g., ethnicity or nationality) to the description of medieval social units. I propose we think of identity as a social construct comprised of three articulating facets, which I call: form, aspect, and definition. The form of identity is its manifestation in behavior and symbolic markers; its aspect is the perception of these forms by people; and its definition is the combination of these perceptions into a social category. Taking an interdisciplinary approach, I examine each facet individually before synthesizing the results. I study the form of identity through an analysis of styles in material culture using a consensus analysis to determine how well objects decorated with the same motif do communicating a shared idea to members of a social group. I explore the aspect of identity through a whole-corpus linguistics approach to Old English, in which I study the co-occurrence of words for "a people" and other semantic fields to refine our understanding of Old English perceptions of social identity. Finally, I investigate the definition of identity by comparing narrations of identity in Old English verse and prose in order to see how authors were able to use vocabulary and imagery to describe the identity of their subjects. In my conclusion I demonstrate that the people of Medieval England had a concept of identity based on the metaphor of a village meeting or a feast, in which smaller, innate groups were thought to aggregate into new heterogeneous wholes. The nature and scale of these groups changed over the course of the Anglo-Saxon period but some of the names used to refer to these units remained constant. Thus, I suggest scholars need to apply a culturally relevant concept of identity when describing the people who lived in Medieval Britain, one that might not match contemporary models, and be cognizant of the fact that medieval groups were not the same as their modern descendants.

Description
This dissertation is a detailed rhetorical analysis of interviews with rice farmers in central Java, Indonesia and documents published by the global NGOs United Nations Food and Agriculture Organization (FAO) and CGIAR. Using theories of materiality, literacies, and environmental rhetorics, I examine how seemingly distinct and disparate humans, organizations, and inanimates are actually entangled agents in a dynamic conversation. I have termed that conversation the discourse of rice farming. Studying local and global together challenges conventional dichotomous thinking about farming and food. Looking at this conversation as an entanglement reveals what Karen Barad has defined in Meeting the Universe Halfway as the intra-relatedness of all agents. I focus on rice farming because rice is a food staple around the world and a major component of global agriculture initiatives by FAO and CGIAR. I argue that farmers construct their jobs in terms of production, food sovereignty, and community. The NGOs construct agriculture in terms of consumption, food security, and poverty alleviation. In my project I emphasize the need for global agents to better account for how farmers construct agriculture. Accounting for how all agents impact the discourse of rice farming is the only way to come to an objective understanding rice farming's impact on local and global scales. My argument adds to the field of environmental rhetorics because most published case studies are about the United States and thus are limited in their applicability. And it enriches global conversations about food security and food justice because it shares accounts from actual farmers who are often conspicuously absent from literature on those topics.

Description
Advancing sustainable food systems requires holistic understanding and solutions-oriented approaches that transcend disciplines, so expertise in a variety of subjects is necessary. Proposed solutions are usually technically or socially oriented, but disagreement over the best approach to the future of food dominates the dialogue. Technological optimists argue that scientific advances are necessary to feed the world, but environmental purists believe that reductions in consumption and waste are sufficient and less risky. Life cycle assessment (LCA) helps resolve debates through quantitative analysis of environmental impacts from products which serve the same function. LCA used to compare dietary choices reveals that simple plant-based diets are better for the environment than diets that include animal products. However, analysis of soy protein isolate (SPI) demonstrates that certain plant-based proteins may be less preferable for the environment than some unprocessed meats in several categories due to additional impacts that come from industrial processing. LCAs' focus on production risks ignoring consumers, but the food system exists to serve consumers, who can be major drivers of change. Therefore, the path to a sustainable food system requires addressing consumption issues as well. Existing methods for advancing sustainable food systems that equate more information with better behavior or performance are insufficient to create change. Addressing food system issues requires sufficient tacit knowledge to understand how arguments are framed, what the supporting content is, the findings of primary sources, and complex and controversial dialogue surrounding innovations and interventions for food system sustainability. This level of expertise is called interactional competence and it is necessary to drive and maintain holistic progress towards sustainability. Development strategies for interactional competence are informed by studying the motivations and strategies utilized by vegans. A new methodology helps advance understanding of expertise development by assessing levels of expertise and reveals insights into how vegans maintain commitment to a principle that influences their daily lives. The study of veganism and expertise reveals that while providing information to debunk fallacies is important, the development of tacit knowledge is fundamental to advance to a stage of competence.

Description
Without scientific expertise, society may make catastrophically poor choices when faced with problems such as climate change. However, scientists who engage society with normative questions face tension between advocacy and the social norms of science that call for objectivity and neutrality. Policy established in 2011 by the Intergovernmental Panel on Climate Change (IPCC) required their communication to be objective and neutral and this research comprised a qualitative analysis of IPCC reports to consider how much of their communication is strictly factual (Objective), and value-free (Neutral), and to consider how their communication had changed from 1990 to 2013. Further research comprised a qualitative analysis of structured interviews with scientists and non-scientists who were professionally engaged in climate science communication, to consider practitioner views on advocacy. The literature and the structured interviews revealed a conflicting range of definitions for advocacy versus objectivity and neutrality. The practitioners that were interviewed struggled to separate objective and neutral science from attempts to persuade, and the IPCC reports contained a substantial amount of communication that was not strictly factual and value-free. This research found that science communication often blurred the distinction between facts and values, imbuing the subjective with the authority and credibility of science, and thereby damaging the foundation for scientific credibility. This research proposes a strict definition for factual and value-free as a means to separate science from advocacy, to better protect the credibility of science, and better prepare scientists to negotiate contentious science-based policy issues. The normative dimension of sustainability will likely entangle scientists in advocacy or the appearance of it, and this research may be generalizable to sustainability.

Description
This work challenges the conventional perceptions surrounding the utility and use of the CMS Open Payments data. I suggest unconsidered methodologies for extracting meaningful information from these data following an exploratory analysis of the 2014 research dataset that, in turn, enhance its value as a public good. This dataset is favored for analysis over the general payments dataset as it is believed that generating transparency in the pharmaceutical and medical device R&D process would be of the greatest benefit to public health. The research dataset has been largely ignored by analysts and this may be one of the few works that have accomplished a comprehensive exploratory analysis of these data. If we are to extract valuable information from this dataset, we must alter both our approach as well as focus our attention towards re-conceptualizing the questions that we ask. Adopting the theoretical framework of complex systems serves as the foundation for our interpretation of the research dataset. This framework, in conjunction with a methodological toolkit for network analysis, may set a precedent for the development of alternative perspectives that allow for novel interpretations of the information that big data attempts to convey. By thus proposing a novel perspective in interpreting the information that this dataset contains, it is possible to gain insight into the emergent dynamics of the collaborative relationships that are established during the pharmaceutical and medical device R&D process.

Description
Collaborative research is not only a form of social and human capital and a public good, but also a fundamental elicitor of positive Collective Action. Collaborative Research Networks can serve as models of proactive and purposive Collective Action and catalysts of societal change, if they function as more than hubs of research and knowledge. It is the goal of this Honors Thesis to examine the current nature under which collaborative research networks, focused on matters of Global Health or Sustainability, operate., how they are organized, what type of collaboration they engage in, and who collaborates with whom. A better understanding of these types of networks can lead to the formation of more effective networks that can develop innovative solutions to our collective Global Health and Sustainability problems.

Description
A pressing question in public policymaking is how best to allocate decision-making authority and to facilitate opportunities for input. When it comes to science, technology, and environmental (STE) policy decisions, persons impacted by those decisions often have relevant information and perspectives to contribute yet lack either the specialized, technical knowledge or the means by which to effectively communicate that knowledge. Consequently, due to a variety of factors, they are frequently denied meaningful involvement in making them. In an effort to better understand why this is so, and how this might change, this dissertation uses an activity systems framework to examine how three factors mediate the circulation of information in STE public engagement mechanisms.
In this project, I examine the transcripts of a 2015 administrative hearing and community meeting about the Santa Susana Field Lab—a former nuclear- and rocket engine-testing facility 30 miles from Los Angeles, where an experimental nuclear reactor suffered a partial meltdown in 1959. Specifically, I identify (1) who was designated as an "expert" versus a member of "the public," (2) the structural features, and (3) the stylistic features of participants' remarks at these events; and I study how these factors mediated the flow of information at each. To do so, I view "expert" and "public" as what Michael McGee has termed ideographs, and consider the structural and stylistic features that prior scholarship has identified to impact information flow.
Based on my analysis, I theorize that role designations, structural features, and stylistic features work together to mediate whose, what, and how information flows in public engagement mechanisms. Based on my findings, I also suggest that this mediation impacts policy outcomes. As such, I contend that better understanding the relationships among these mediational means, information flow, and policy outcomes is an important step towards developing public engagement mechanisms that most effectively use the relevant knowledge and other insights of all who have a stake in policy decisions.

Description
Ethos or credibility of a speaker is often defined as the speaker's character (Aristotle). Contemporary scholars however, have contended that ethos lies with the audience because while the speaker may efficiently persuade, the audience will decide if it wants to be persuaded (Farrell). Missing from the scholarly conversation is attention to how ethos is performed between speaker and audience under institutional structures that produce inequitable power relations subject to changing political contexts over time. In this dissertation I analyze how ethos is performed that is a function of a specific social and political environment.
My grandfather, Al Foon Lai, was a paper son. As an adult, I learned that paper sons were members of paper families that may or may not actually exist except on paper; furthermore paper immigration was the way many Chinese entered the United States to get around the Chinese Exclusion Act (1882-1943). Grandfather held legal status, but grandfather's name was fictitious and thus his entry to the United States in 1920 was illegal. Today by some authorities he would be classified as an illegal immigrant. As Grandfather's status as a paper son suggest, Grandfather's credibility as someone with the legal prerogative to reside in the U.S. was a dynamic construct that was negotiated in light of the changing cultural norms encoded in shifting immigration policies. Grandfather constructed his ethos "to do persuasion" in administrative hearings mandated under the Chinese Exclusion Act that produced asymmetrical power relations. By asymmetrical power relations I mean the unequal status between the administrator overseeing the hearing and Lai the immigrant. The unequal status was manifest in the techniques and procedures employed by the administrative body empowered to implement the Chinese Exclusion Act and subsequent laws that affected Chinese immigrants. Combining tools from narrative analysis and feminists rhetorical methods I analyze excerpts from Al Foon Lai's transcripts from three administrative hearings between 1926 and 1965. It finds that Grandfather employed narrative strategies that show the nature of negotiating ethos in asymmetrical power situations and the link between the performance of ethos and the political and social context.
