Description
The Leukemia and Lymphoma Society (LLS) is a nonprofit organization with a mission to fund research for cures and treatments for blood-related cancer. Light The Night is one of the largest peer-to-peer (P2P) fundraising events, with approximately 1 million participants in 140 locations throughout the United States and Canada. Participants walk with illuminated lanterns to commemorate survivors, friends, family, and supporters. Sustainability has become a recent concern for the organization's corporate partners and participants. LLS has shown an increased dedication to sustainability by creating an Environmental Social Governance (ESG) council and has started taking steps toward creating a national plan for sustainability at its Light The Night events.
In order to extend sustainability efforts to all Light The Night events, the client requests
the Sustainable Light Knights team to:
1. Perform a materiality assessment for the Light The Night event, accounting for the recent changes that seek to minimize sustainability practices.
2. Rank the event's most material activities, considering food and beverage, waste, lanterns, and t-shirts.
3. Assess the best practices for managing the highest material impacts.
4. Identify short, medium, and long-term goals to help LLS plan for the next steps.
The Sustainable Light Knights consist of four Arizona State University graduate students from the Masters of Sustainability Solutions program. The team undertook an analytical approach to understand P2P events, including conducting a landscape analysis, identifying best practices, and completing a TOWS (threats, opportunities, weaknesses, and strengths) analysis. This served as the foundation for the materiality assessment for Light The Night, which guided what impact topics were most relevant.
To bring the findings of the materiality matrix to life, The Sustainable Light Knights created a sustainable event planning checklist, procurement guidelines, and a vendor pledge for use by Light The Night staff. We grouped the recommendations for sustainable actions into low, medium, and high priority and short, medium, and long-term goals. While this assessment focused on Light The Night, the recommendations outlined in this action plan can extend to other fundraising events organized by LLS. The design of the action plan is to help LLS leadership and staff take steps to lower the impact of Light The Night events nationwide and transform LLS into a leader within sustainable events that can serve as an example for other nonprofit organizations to follow.

Description
Both molecular structure of macromolecular materials and subsequent processing of these materials dictate resulting material properties. In this work novel synthetic strategies combined with detailed analytical methodology reveal fundamental structure-processing-property relationships in thermoplastic polyesters, thermoplastic polyurethanes, covalently crosslinked acetal functionalized networks, and small molecule surfactants. 4,4’ dimethyloxybisbenzoate afforded a series of novel polyester structures, and the incorporation of this monomer both increased the Tg and decreased the crystallinity in cyclohexane dimethanol based polyesters. Solubility and dynamic light scattering experiments combined with oscillatory rheology techniques provided methodology to validate polyurethane extrusion in commercial polyurethanes. Acid catalyzed hydroxyl addition to vinyl ethers provided two families of acetal functionalized poly(ethylene glycol hydrogels). Stoichiometric control of binary thiol-acrylate polymerizations afforded hydrogels with both tunable mechanical properties and predictable degradation profiles. Following this work, a photoacid generator catalyzed cationic catalysis provided acetal functionalized organogels whose mechanical properties were predicted by excess vinyl ether monomers which underwent cationic polymerization under the same reaction conditions that yielded acetal functionalization. Time resolved FT-IR spectroscopy provided new understanding in hydroxyl vinyl ether reactions, where both hydroxyl addition to a vinyl ether and vinyl ether cationic polymerization occur concurrently. This work inspired research into new reactive systems for photobase generator applications. However, current photobase generator technologies proved incompatible for carbon-Michael reactions between acetoacetate and acrylate functionalities as a result of uncontrollable acrylate free radical polymerization. The fundamental knowledge and synthetic strategies afforded by these investigations were applied to small molecule surfactant systems for fire-fighting applications. Triethylsilyl-containing zwitterionic and cationic surfactants displayed surface tensions lower than hydrocarbon surfactants, but larger than siloxane-containing surfactants. For the first time, oscillatory rheology and polarized optical light imagine rheology highlighted shear-induced micelle alignment in triethylsilyl surfactants, which provided more stable foams than zwitterionic analogues. The knowledge gained from these investigations provided fundamental structure-processing-property relationships in small molecule surfactant solutions applied as fire-fighting foams. This discovery regarding the effect of self-assembled structures in foam solutions informs the design and analysis of next generation surfactants to replace fluorocarbon surfactants in fire-fighting foam applications.

Description
Acrylate polymers are a versatile class of polymers that have found extensive applications in diverse fields, including adhesive, coatings, packaging, cosmetics, textile, food, electronics, and automotive industries. Incorporating crosslinking elements such as supramolecular chemistry or photoreactive group imparts unique and desirable properties to the resulting acrylate polymers. In the first project, regioselective Michael addition allowed the efficient installation of the nucleobase, guanine and cytosine, on acrylate-containing monomers, which enabled the preparation of a series of nucleobase functionalized acrylate and n-butyl acrylate copolymers using conventional free radical copolymerization. Guanine-containing copolymers exhibited superior thermal, thermomechanical, and morphological properties than cytosine-containing copolymer analogs due to the relatively strong guanine self-association. Further understanding of rheological, mechanical, and adhesive properties revealed the influence of guanine content and provided valuable information for designing and optimizing guanine-containing copolymers for elastomers and adhesives. Controlled radical polymerization enabled the synthesis of guanine and cytosine-containing triblock copolymers. Blending these two triblock copolymers formed supramolecular networks through molecular recognitions between guanine and cytosine and enhanced polymer self-assembly. Next, incorporating spiropyran photoisomerization functional groups in the acrylate copolymer enabled the formation of zwitterionic polymers upon ultraviolet (UV) radiation, which facilitated the Cu ion removal from aqueous solutions. The final project aimed to synthesize a family of macro-crosslinkers bearing an acrylate pendant group, which demonstrated compatibility with versatile reactive diluents, such as poly(dimethyl siloxane) and epoxy. The designed macro-crosslinkers showed promise in developing UV adhesives with desirable properties, such as low shrinkage, fast curing, and high thermal stability. These projects offered valuable insights into the fundamental structure-property-morphology relationships in crosslinked acrylic polymers that incorporate supramolecular chemistry or photoreactive functional groups, paving the way for new advances in the design of acrylate polymer with enhanced mechanical and morphological properties.

Description
After many decades of promoting sustainable tourism and development, the world faces the pressing issue of overtourism. Overtourism is viewed as the condition where the growth of visitor volume puts destinations’ capacity under pressure resulting in many negative impacts on the environment, economy, culture, and society. It causes many community residents to resent tourism development. Visitors are concerned about their travel experience in overcrowded places. Understanding overtourism is necessary for destination management. This dissertation includes three studies to: 1) review the phenomenon of overtourism; 2) examine the perceptions of local residents and test the relationship between their satisfaction with quality of life and level of support for tourism development in overtourism context; and 3) examine the management of stakeholder involvement in an evidence-based sustainable tourism plan that aims to address overtourism. Different research methods are employed in the three studies of the dissertation: a conceptual paper based on literature review; a concurrent triangulation approach using both quantitative and qualitative data collected from a survey with host community; and a case study involving analysis of documents related to a sustainable tourism plan and in-depth interviews with key informants who were involved in developing the plan. Several theoretical or conceptual frameworks are used to guide research, including those that consider the relationship between residents’ satisfaction with QOL and their support for tourism development, crowding theory, stress coping framework, place attachment, and a multi-stakeholder involvement management framework. Sedona, a destination that is concerned about overtourism, was chosen to be the research site for two of the studies. Study 1 reveals the complexity of overtourism and pinpoints important aspects and details (e.g., causes, impacts) that need to be considered while solving overtourism. Study 2 investigates impacts of overtourism on the quality of life of the host community and identifies different ways residents cope with the crowding condition. Residents’ support for tourism development is influenced by their satisfaction with quality of life and possibly by their attachment to destination. Study 3 documents a comprehensive mechanism to manage stakeholder involvement and utilization of evidence in a sustainable tourism plan. Findings are helpful for destination management.

Description
Nature-based recreation is a popular way for people to interact with the environment that also confers numerous economic and health benefits. It is important that the social-ecological systems (SES) that host nature-based recreation be managed effectively, both to preserve the benefits of this important human-environment interaction, and to avoid the potential negative outcomes of recreational commons. The SES that host nature-based recreation are characterized by complex and dynamic feedbacks that complicate their management. Managing these systems is made more complex by the suite of external, multi-scalar, and anthropogenic forces (e.g., climate change, trans-boundary pollution) that plague them with increasing frequency. This dissertation investigates the importance of accounting for this full range of system feedbacks when managing for nature-based recreation. I begin with a broad discussion of the types of dilemmas faced by managers of nature-based recreation. I create a systems-thinking typology of management dilemmas that apply across different recreation modes and system contexts, and which are characterized as feedbacks within the broader recreational system. My findings in this chapter have important implications for understanding and anticipating how different exogenous and endogenous shocks (including management interventions, themselves) may work through or change the processes in SES that host nature-based recreation. In the following two chapters, I narrow my focus to examine case studies of specific dilemma archetypes and proposed management interventions. First, I perform an ex ante analysis of a prospective policy response to a regulatory spiral of excess recreational fishing effort and abridged fishing seasons in the U.S. Gulf of Mexico. I estimate behavioral models of fishers’ responses to a prospective incentive-based intervention, and find evidence that such a policy could improve multiple fishery outcomes. Second, I perform an ex post program evaluation of an invasive species bounty program. My results suggest that the program underperformed because it failed to overcome countervailing incentives. Together, my case study analyses reveal the value of modeling for designing policy for these complex SES and show the importance of accounting for the full set of system feedbacks (including the incentives that drive recreator behaviors and the impacts of those behaviors) when managing nature-based recreation.

Description
Dear reader, I hope you will read this entire dissertation. If you are reluctant because of its length, I invite you to contact me for a conversation instead. Over the past eight years I have been a part of three unfolding histories: colonialism, sustainability science, and the Atlas of Creative Tools (the Atlas). In this dissertation I describe how I am a part of these histories. I advocate for partnering them so that the Atlas is used by people in the field of sustainability science to advance cognitive justice in their work. This advocacy is supported by research conducted using a mixed-methods approach. I combine qualitative methods used to study each of the three histories with the experiential knowledge I gained from being a part of them. Throughout the dissertation I move back and forth between academic research and experiential knowledge. Each informs the other. This back-and-forth movement is itself a method to interrogate the assumptions of dissertation writing. My purposes for doing so are two-fold. I want to honor the dissertation as a form of knowledge production that can promote cognitive justice while also pointing out how it hinders it. Additionally, the back-and-forth interrogation method involves using creative tools from the Atlas in the text itself. This demonstrates how the Atlas can be used to promote cognitive justice while producing knowledge in sustainability science. I structure this dissertation to aid you in four ways. First, I provide a view of sustainability science as a contested space that people can and do use to advance cognitive justice. Second, I write about my research and analysis of the Atlas so that my descriptions can be used right away by other practitioners who are working with the Atlas. Third, my methods for interrogating the dissertation itself are meant to be used, modified, and built on by others. Finally, I hope that the connections I make between the Atlas and sustainability science are helpful for your work, and that they inspire you to try the Atlas and see how you can use it to promote cognitive justice in your own contexts.
