Description
Social Carrying Capacity (SCC) has been used commonly in the past to study the impact of increasing numbers of tourists on tourists’ satisfaction with a destination. However, it has been used less commonly to research the impact of increasing levels of tourism on residents of tourism destinations. As definitions of sustainable tourism shift to be more inclusive of residents, commonly used constructs should also be refined or modified to reflect this ontological shift. Current operational definitions of SCC tend to focus on crowding as the major indicator SCC has been reached. Even the theories commonly used to study SCC, stimulus-overload and expectancy theories, relate directly to crowding. This Master’s thesis aimed to expand the concept of SCC to be more representative of the manifold impacts experienced by residents of tourism destinations as tourism increases. This aim was accomplished through an exploratory mixed methods study ultimately resulting in the creation of a new SCC measurement tool.
The qualitative phase of this research consisted of four focus groups in three sites with varying levels of tourism development. The data from the focus groups were used to inform item writing of a measurement tool that represented a greater number of SCC indicators than crowding to confirm the validity of the indicators in the quantitative phase of the research. After the instrument was distributed via a statewide poll, two structural equation models were fit to compare the operational definitions. A better understanding of the relationship between one of the supporting theories, stimulus-overload theory, and SCC was uncovered with evidence of an emergent connection between SCC and tourism-related stressors.
The results of the research indicate that there are multiple indicators of SCC experienced by residents of tourism destinations which can change in degree and expression as tourism development in a community increases. The operational definition including these indicators explained more variance in support for tourism development than overcrowding alone. A greater awareness of these indicators and their evolution can strengthen the theoretical foundation of SCC and enable practitioners to make multi-faceted, proactive decisions when managing a destination.

Description
This thesis intends to help inform American Indian nations’ decision making related to housing. The study recognizes the urgent need for housing solutions that fit the needs of a community as well as benefit the overall ecosystem. One model that can offer guidance is the Circular Economy (CE) model. A well-thought-out CE process can provide housing solutions that are economically, socially, and environmentally sustainable. It also stimulates the local economy by strategically introducing positive changes. This research identifies the construction potential of available circular materials as compared to more contemporary building materials. It then recommends a closed-loop circular model that utilizes the community’s existing infrastructure to develop affordable housing. The proposed CE model operates within the built environment, stimulating local employment while catering to the needs of the residents. Such an approach can prove to be beneficial for the local community and perhaps scalable to the global economy.

Description
Universities and colleges in the United States (U.S.) are in a period of rapid transformation. Driven by the need for an educated workforce, higher education institutions are responding to rapid innovation, globalization, economic realities, and sociodemographic shifts. Simultaneously, extensive educational online networks connect millions of people worldwide enable learning and knowledge sharing beyond what society has experienced to date. In light of technological advancements, the preservation and presentation of certain ideals that undergird academia and the communication and application of knowledge are undergoing dramatic change. Within higher education, this is both a challenge and an opportunity to re-envision the commitment to educate the public. This research discusses potential forms of this redesign and how it can build upon and depart from previous iterations of higher education. How colleges and universities will adapt to become more relevant, engaging, and accessible is a pressing question that must be addressed.
Using case studies focused on creating sustainability education materials, this dissertation develops knowledge related to three interconnected areas of study that will contribute to redesigning higher education through participatory action research methodology. First, higher education has a civic responsibility to provide new ways of thinking, being, and doing globally and providing more access to education to broader society, especially through public research institutions. Second, with a vast array of available learning materials, higher education should invest in elegantly-designed experiences consisting of well-reasoned, meticulously-curated, and high-quality content that is aesthetically appealing, engaging, and accessible to a broad audience. Third, as universities transition from the gatekeepers of knowledge to the connectors of knowledge, they also need to ensure that a coherent mission is articulated and invested in by stakeholders to create an intentionally beneficial transformational effort. The transformation of higher education toward a more inclusive learning environment through new ways of thinking and elegantly-designed learning experiences will serve to improve our learning institutions. As part of the necessary core for an educated democracy, higher education institutions must strive to create a more equitable, inclusive, and diverse society.

Description
Predominant sustainability pedagogy and science largely focus on fixing existingproblems via solutions external to humans (e.g. carbon sequestration, renewable energy).
While external or outer interventions can support a transition to a sustainable future,
internal or inner developments should also be highly valued. For this dissertation, I define
sustainability as the ability of any individual, community or country to meet their needs
and live happily without compromising the ability of other individuals, communities,
countries and future generations to meet their needs and live happily. Framed this way, a
sustainable and happy life should focus on both outer and inner development, the latter
largely unconsidered in sustainability science and scholarship.
I propose that emphasizing spiritual wellbeing and spiritual practices can support
individuals and communities to act with mindfulness, awareness, compassion,
connection, and love, transitioning to a more sustainable existence. This dissertation
consists of three studies: (1) the development of a theoretical framework identifying
spirituality as the missing link between sustainability and happiness, (2) an empirical
pilot study testing the theoretical framework via contemplative practices in a
sustainability classroom, and (3) an autoethnography exploring my inner development
and transformation as a sustainability and spirituality researcher over the past four years.
The theoretical framework found and posits, based on existing literature, that
spirituality indeed may be the missing link between an unsustainable existence and a
sustainably and happy future. Results from the empirical study suggest that a focus on
spirituality leads students to develop inner traits necessary for sustainable behavior and a
deeper understanding of sustainability. My autoethnography demonstrates the spiritual
ii
transformation possible from integrating spiritual well-being and intellect, while striving
to embody sustainability as a spiritual journey. My research supports further studies and a
greater understanding of the importance of spiritual well-being to sustainability and the
incorporation of contemplative practices in sustainability classrooms. Finally, I hope this
dissertation will (1) inspire sustainability scientists, researchers, and students to integrate
spiritual well-being as an important part of their lives and work, and (2) encourage deeper
conversations about the radical inner shift we need to achieve lasting sustainability for all
beings.

Description
The current sustainability crisis is born from a specious notion that humans are separate from and in a position of control over nature. In response, this dissertation reconceptualizes education beyond its current anthropocentric model to imagine education as learning through relationality with all that is ‘beyond’ the human. The study leaves behind hegemonic binary distinctions (human
ature, teacher/student, formal
on-formal education) to reimagine education as a multidirectional process of learning as worlding and becoming-with Earth (Haraway, 2016a). It explores what matters in education and how it comes to matter.
This dissertation introduces the concept of storyworlding to describe what occurs when multispecies, multi-mattered assemblages (re)write Earth’s narratives through their relationships with one another. Taking its inspiration from the work of the Common Worlds Research Collective, Donna Haraway, and Isabelle Stengers, storyworlding acknowledges that the relationships between and among all biotic and abiotic forces on Earth make stories through their interactions, and these stories make a pluriverse of worlds.
The study is structured as a natureculture (Haraway, 2003) ethnography. This innovation on ethnography, a traditionally human-centered method, focuses on agential, multispecies/ multi-mattered assemblages rather than the description of human culture. Data is not generated and then labeled as fixed in this study. It is emergent in its assemblages as a co-narrator in sympoietic storyworlding (Haraway, 2016b).
Data generation took place over 6 months in a small, coffee-producing region of Southeastern Brazil. Data generation methods included walking conversations with children and the more-than-human world, participation in a multi-grade, one-room schoolhouse, and the collection of visual and audio data such as drawings, photographs, videos, and audio recordings.
Using an intentionally slow, messy, and fluid diffractive analysis, I follow the data where it leads as I think with the concept of storyworlding (Barad, 2007; Mazzei, 2014). Drawing inspiration from Donna Haraway, Isabelle Stengers, and Iveta Silova, the dissertation concludes with an Epilogue of speculative fabulation (SF) imaginings through which I invite the reader to engage in the thought experiment of reimagining not only what matters in education, but what education, itself, is.

Description
The construction industry generates tremendous amounts of data every day. Data can inform practitioners to increase their project performance as well as the quality of the resulting built environment. The data gathered from each stage has unique characteristics, and processing them to the appropriate information is critical. However, it is often difficult to measure the impact of the research across project phases (i.e., planning, design, construction, operation and maintenance, and end-of-life). The goal of this dissertation is to present how industry data can be used to make an impact on construction practices and test a suite of methods to measure the impact of construction research across project phases. The dissertation provides examples of impactful research studies for each project phase to demonstrate the collection and utilization of data generated from each stage and to assess the potential tangible impact on construction industry practices. The completed studies presented both quantitative and qualitative analyses. The first study focuses on the planning phase and provides a practice to improve frond end planning (FEP) implementation by developing the project definition rating index (PDRI) maturity and accuracy total rating system (MATRS). The second study uses earned value management system (EVMS) information from the design and construction phases to support reliable project control and management. The dissertation then provides a third study, this time focusing on the operations phase and comparing the impact of project delivery methods using the international roughness index (IRI). Lastly, the end-of-life or decommissioning phase is tackled through a study that gauges the monetary impact of the circular economy concept applied to reuse construction and demolition (C&D) waste. This dissertation measures the impact of the research according to the knowledge mobilization (KMb) theory, which illustrates the value of the work to the public and to practitioners.

Description
The continued reliance on fossil fuel for energy resources has proven to be unsustainable, leading to depletion of world reserves and emission of greenhouse gases during their combustion. Therefore, research initiatives to develop potentially carbon-neutral biofuels were given the highest importance. Hydrothermal liquefaction (HTL, a thermochemical conversion process) of microalgae is recognized as a favorable and efficient technique to produce liquid biofuels from wet feedstocks. In this work, three different microalgae (Kirchneriella sp., Galdieria sulphuraria, Micractinium sp.) grown and harvested at Arizona State University were hydrothermally liquefied to optimize their process conditions under different temperatures (200-375 °C), residence times (15-60 min), solids loadings (10-20 wt.%), and process pressures (9-24 MPa). A one-factor-at-a-time approach was employed, and comprehensive experiments were conducted at 10 % solid loadings and a residence time of 30 min. Co-liquefaction of Salicornia bigelovii Torr. (SL), Swine manure (SM) with Cyanidioschyzon merolae (CM) was tested for the presence of synergy. A positive synergistic effect was observed during the co-liquefaction of biomasses, where the experimental yield (32.95 wt.%) of biocrude oil was higher than the expected value (29.23 wt.% ). Co-liquefaction also led to an increase in the energy content of the co-liquefied biocrude oil and a higher energy recovery rate ( 88.55 %). The HTL biocrude was measured for energy content, elemental, and chemical composition using GC-MS. HTL aqueous phase was analyzed for potential co-products by spectrophotometric techniques and is rich in soluble carbohydrates, dissolved ammoniacal nitrogen, and phosphates. HTL biochar was studied for its nutrient content (nitrogen and phosphorous) and viability of its recovery to cultivate algae without any inhibition using the nutrient leaching. HTL biochar was also studied to produce hydrogen via pyrolysis using a membrane reactor at 500 °C, 1 atm, for 24 h to produce 5.93 wt.% gas. The gaseous product contains 45.7 mol % H2, 44.05 ml % CH4, and 10.25 mol % of CO. The versatile applications of HTL biochar were proposed from a detailed physicochemical characterization. The metal impurities in the algae, bio-oil, and biochar were quantified by ICP-OES where algae and biochar contain a large proportion of phosphorous and magnesium.

Description
Cities are in need of radical knowledge system innovations and designs in the age of the Anthropocene. Cities are complex sites of interactions across social, ecological, and technological dimensions. Cities are also experiencing rapidly changing and intractable environmental conditions. Given uncertain and incomplete knowledge of both future environmental conditions and the outcomes of urban resilience efforts, today’s knowledge systems are unequipped to generate the knowledge and wisdom needed to act. As such, cities must modernize the knowledge infrastructure underpinning today’s complex urban systems. The principal objective of this dissertation is to make the case for, and guide, the vital knowledge system innovations that coastal cities need in order to build more resilient urban futures. Chapter 2 demonstrates the use of knowledge systems analysis as a tool to stress-test and upgrade the Federal Emergency Management Agency flood mapping knowledge system that drives flood resilience planning and decision-making in New York City. In Chapter 3, a conceptual framework is constructed for the design and analysis of knowledge co-production by integrating concepts across the co-production and urban social-ecological-technological systems literatures. In Chapter 4, the conceptual framework is used to analyze two case studies of knowledge co-production in the Miami Metropolitan Area to better inform decisions for how and when to employ co-production as a tool to achieve sustainability and resilience outcomes. In Chapter 5, six propositions are presented – derived from a synthesis of the literature and the three empirical cases – that knowledge professionals can employ to create, facilitate, and scale up knowledge system innovations: flatten knowledge hierarchies; create plural and positive visions of the future; construct knowledge co-production to achieve desired outcomes; acknowledge and anticipate the influence of power and authority; build anticipatory capacities to act under deep uncertainty; and identify and invest in knowledge innovations. While these six propositions apply to the context of coastal cities and flood resilience, most can also be useful to facilitate knowledge innovations to adapt to other complex and intractable environmental problems. Cities must move swiftly to create and catalyze knowledge system innovations given the scale of climate impacts and rapidly changing environmental conditions.

Description
The science community has made efforts for over a half century to address sustainable development, which gave birth to sustainability science at the turn of the twenty-first century. Along with the development of sustainability science during the past two decades, a landscape sustainability science (LSS) perspective has been emerging. As interests in LSS continue to grow rapidly, scholars are wondering what LSS is about and how LSS fits into sustainability science, while practitioners are asking how LSS actually contributes to sustainability in the real world. To help address these questions, this dissertation research aims to explore the currently underused problem-driven, diagnostic approach to enhancing landscape sustainability through an empirical example of urbanization-associated farmland loss (UAFL). Based mainly on multimethod analysis of bibliographic information, the dissertation explores conceptual issues such as how sustainability science differs from conventional sustainable development research, and how the past, present, and future research needs of LSS evolve. It also includes two empirical studies diagnosing the issue of urban expansion and the related food security concern in the context of China, and proposes a different problem framing for farmland preservation such that stakeholders can be more effectively mobilized. The most important findings are: (1) Sustainability science is not “old wine in a new bottle,” and in particular, is featured by its complex human-environment systems perspective and value-laden transdisciplinary perspective. (2) LSS has become a vibrant emerging field since 2004-2006 with over three-decade’s intellectual accumulation deeply rooted in landscape ecology, yet LSS has to further embrace the two featured perspectives of sustainability science and to conduct more problem-driven, diagnostic studies of concrete landscape-relevant sustainability concerns. (3) Farmland preservationists’ existing problem framing of UAFL is inappropriate for its invalid causal attribution (i.e., urban expansion is responsible for farmland loss; farmland loss is responsible for decreasing grain production; and decreasing grain production instead of increasing grain demand is responsible for grain self-insufficiency); the real problem with UAFL is social injustice due to collective action dilemma in preserving farmland for regional and global food sufficiency. The present research provides broad implications for landscape scientists, the sustainability research community, and UAFL stakeholders.

Description
Phosphorus (P) is a limiting nutrient in ecosystems and is mainly used as fertilizer to grow food. The demand for P is increasing due to the need for increased food supply to support a growing population. However, P is obtained from phosphate rock, a finite resource that takes millions of years to form. These phosphate rock deposits are found in only a few countries. This uneven distribution of phosphate rock leads to a potential imbalance in socio-economic systems, generating food security pressure due to unaffordability of P fertilizer. Thus, the first P-sustainability concern is a stable supply of affordable P fertilizer for agriculture. In addition, improper management of P from field to fork leaves an open end in the global P cycle that results in widespread water pollution. This eutrophication leads to toxic algal blooms and hypoxic “dead zones”. Thus, the second P-sustainability concern involves P pollution from agriculture and cities. This thesis focuses on P flows in a city (Macau as a case study) and on potential strategies for improvements of sustainable P management in city and agriculture. Chapter 2 showed a P-substance-flow analysis for Macau from 1998-2016. Macau is a city with a unique economy build on tourism. The major P flows into Macau were from food, detergent, and sand (for land reclamation). P recovery from wastewater treatment could enhance Macau’s overall P sustainability if the recovered P could be directed towards replacing mined P used to produce food. Chapters 3 and 4 tested a combination of P sustainability management tactics including recycling P from cities and enhancing P-use efficiency (PUE) in agriculture. Algae and biosolids were used as recycled-P fertilizers, and genetically transformed lettuce was used as the a PUE-enhanced crop. This P sustainable system was compared to the conventional agricultural system using commercial fertilizer and the wild type lettuce. Chapters 3 and 4 showed that trying to combine a PUE-enhancement strategy with P recycling did not work well, although organic fertilizers like algae and biosolids may be more beneficial as part of longer-term agricultural practices. This would be a good area for future research.
