environmental governance: the vision for a Green Economy and the growing influence of non-state actors. The work draws on multi-sited thick description to analyze how relationships between the state, market, and civil society are being reoriented towards global problems. Its focus is a non-binding agreement between California and Chiapas to create a market in carbon offsets credits for Reducing Emissions for Deforestation and forest Degradation (REDD). The study draws on three bodies of scholarship. From the institutionalist study of global environmental politics, it uses the ideas of orchestration, civil regulation, and private entrepreneurial authority to identity emerging alignments of state and non-state actors, premised on an exchange of public authority and private expertise. From concepts borrowed from science and technology studies, it inquires into the production, certification, and contestation of knowledge. From a constitutionalist perspective, it analyzes how new forms of public law and private expertise are reshaping foundational categories such as territory, authority, and rights. The analysis begins with general research questions applied to California and Chiapas, and the international space where groups influential in these sites are also active: 1) Where are new political and legal institutions emerging, and how are they structured? 2) What role does scientific, legal, and administrative expertise play in shaping these institutions, and vice versa? And 3) How are constitutional elements of the political order being reoriented towards these new spaces and away from the exclusive domain of the nation-state? The dissertation offers a number of propositions for combining institutionalist and constructivist approaches for the study of complex global governing arrangements. It argues that this can help identify constitutional reconfigurations that are not readily apparent using either approach alone.
To answer this question, I used a multipronged approach to triangulate a richer understanding of what art-science synthesis offers sustainability and how it functions. First, I performed an historical analysis of a maladapted wilderness aesthetic and turned to the work Aldo Leopold – an exemplar of an artist-scientist – for a new sustainability aesthetic. Then, I engaged in an individual contemporary art practice, culminating in a gallery exhibit, which displayed ecologically-informed work from a three year study of my backyard. Finally, I conducted small group research of artist-scientist teams tasked with developing interpretive signage for the Tres Rios wetland site. For this final element, I collected survey, wearable sensor, and ethnographic data.
Through this composite research, I found that successful art-science practices require significant energy and time investment. Although art-science is most intensive in an individual practice where the person must become “fluent” in two disciplines, it is still challenging in a group setting where members must become “conversational” in each other’s work. However, successful art-science syntheses appear to result in improved communication skills, better problem articulation, more creative problem solving, and the questioning of personal and disciplinary mental models. Thus, the outcomes of such syntheses warrant the effort required at both the individual and collaborative level.
In addition to the stormwater management function, Vegetative filter strips (VFS) are effective mechanisms for control of sediment flow and soil erosion from agricultural and urban lands. Erosion is a major problem associated with areas subjected to high runoffs or steep slopes across the globe. In order to effect economy in the design of grass filter strips as a mechanism for sediment control & stormwater management, an optimization model is required that minimizes the land requirements for the VFS. The optimization model presented in this study includes an intricate system of equations including the equations defining the sheet flow on the paved and grassed area combined with the equations defining the sediment transport over the vegetative filter strip using a non-linear programming optimization model. In this study, the optimization model has been applied using a sensitivity analysis of parameters such as different soil types, rainfall characteristics etc., performed to validate the model
Three dilemmas plague governance of scientific research and technological
innovation: the dilemma of orientation, the dilemma of legitimacy, and the dilemma of control. The dilemma of orientation risks innovation heedless of long-term implications. The dilemma of legitimacy grapples with delegation of authority in democracies, often at the expense of broader public interest. The dilemma of control poses that the undesirable implications of new technologies are hard to grasp, yet once grasped, all too difficult to remedy. That humanity has innovated itself into the sustainability crisis is a prime manifestation of these dilemmas.
Responsible innovation (RI), with foci on anticipation, inclusion, reflection, coordination, and adaptation, aims to mitigate dilemmas of orientation, legitimacy, and control. The aspiration of RI is to bend the processes of technology development toward more just, sustainable, and societally desirable outcomes. Despite the potential for fruitful interaction across RI’s constitutive domains—sustainability science and social studies of science and technology—most sustainability scientists under-theorize the sociopolitical dimensions of technological systems and most science and technology scholars hesitate to take a normative, solutions-oriented stance. Efforts to advance RI, although notable, entail one-off projects that do not lend themselves to comparative analysis for learning.
In this dissertation, I offer an intervention research framework to aid systematic study of intentional programs of change to advance responsible innovation. Two empirical studies demonstrate the framework in application. An evaluation of Science Outside the Lab presents a program to help early-career scientists and engineers understand the complexities of science policy. An evaluation of a Community Engagement Workshop presents a program to help engineers better look beyond technology, listen to and learn from people, and empower communities. Each program is efficacious in helping scientists and engineers more thoughtfully engage with mediators of science and technology governance dilemmas: Science Outside the Lab in revealing the dilemmas of orientation and legitimacy; Community Engagement Workshop in offering reflexive and inclusive approaches to control. As part of a larger intervention research portfolio, these and other projects hold promise for aiding governance of science and technology through responsible innovation.
This dissertation examines the use of Gram-positive thermophilic (60 ◦C) ARB in MXCs since very little is known regarding the behavior of these microorganisms in this setting. Here, we begin with the draft sequence of the Thermincola ferriacetica genome and reveal the presence of 35 multiheme c-type cytochromes. In addition, we employ electrochemical techniques including cyclic voltammetry (CV) and chronoamperometry (CA) to gain insight into the presence of multiple pathways for extracellular electron transport (EET) and current production (j) limitations in T. ferriacetica biofilms.
Next, Thermoanaerobacter pseudethanolicus, a fermentative ARB, is investigated for its ability to ferment pentose and hexose sugars prior to using its fermentation products, including acetate and lactate, for current production in an MXC. Using CA, current production is tracked over time with the generation and consumption of fermentation products. Using CV, the midpoint potential (EKA) of the T. pseudethanolicus EET pathway is revealed.
Lastly, a cellulolytic microbial consortium was employed for the purpose ofassessing the feasibility of using thermophilic MXCs for the conversion of solid waste into current production. Here, a highly enriched consortium of bacteria, predominately from the Firmicutes phylum, is capable of generating current from solid cellulosic materials.
In recent years, a more sustainable approach integrating economic, socio-cultural and environmental impacts has been suggested when analyzing short term event such as festivals. It is important for event managers and scholars alike to understand these potential impacts as heritage festivals continue to evolve and prevalent part of heritage tourism.
This study aims to measure and quantify the economic, social and environmental impacts of two heritage festivals – Gold Rush Days and Bluegrass Festival, closely following Andersson and Lundberg’s 2013 study on commensurability and sustainability utilizing willingness to pay (WTP) and willingness to accept (WTA). Both are annual heritage festivals and take place in Wickenburg, Arizona. Primary data collection methods are used to gather information regarding economic and social impacts. Paper questionnaires distributed via stratified random sample to festival attendees and town residents is the survey instrument used in the study. To determine environmental impacts, secondary data in the form of stakeholder interviews are conducted.
Findings suggest a positive economic impact to the town of Wickenburg. Visitor expenditures, retained local spending and direct, indirect, and induced impacts are presented. Social impacts show a generally positive attitude toward the festival from a resident perspective. Environmental impacts show that collaboration among town stakeholders is needed to better determine festival environmental impact as no formal measures of impact are currently being recorded. Further empirical research is needed to better determine these impacts.
