Description
As climate change becomes a greater challenge in today's society, it is critical to understand young people's perceptions of the phenomenon because they will become the next generation of decision-makers. This study examines knowledge, beliefs, and behaviors among high school students. The subjects of this study include students from high school science classes in Phoenix, Arizona, and Plainfield, Illinois. Using surveys and small group interviews to engage students in two climatically different locations, three questions were answered:
1) What do American students know and believe about climate change? How is knowledge related to beliefs?
2) What types of behaviors are students exhibiting that may affect climate change? How do beliefs relate to behavioral choices?
3) Do climate change knowledge, beliefs, and behaviors vary between geographic locations in the United States?
The results of this study begin to highlight the differences between knowledge, beliefs, and behaviors around the United States. First, results showed that students have heard of climate change but often confused aspects of the problem, and they tended to focus on causes and impacts, as opposed to solutions. Related to beliefs, students tended to believe that climate change is caused by both humans and natural trends, and would affect plant and animal species more than themselves and their families. Second, students were most likely to participate in individual behaviors such as turning off lights and electronics, and least likely to take public transportation and eat a vegetarian meal. Individual behaviors seem to be most relevant to this age group, in contrast to policy solutions. Third, students in Illinois felt they would be more likely to experience colder temperatures and more precipitation than those in Arizona, where students were more concerned about rising temperatures.
Understanding behaviors, motivations behind beliefs and choices, and barriers to actions can support pro-environmental behavior change. Educational strategies can be employed to more effectively account for the influences on a young person's belief formation and behavior choices. Providing engagement opportunities with location-specific solutions that are more feasible for youth to participate in on their own could also support efforts for behavior change.

Description
The sacred San Francisco Peaks in northern Arizona have been at the center of a series of land development controversies since the 1800s. Most recently, a controversy arose over a proposal by the ski area on the Peaks to use 100% reclaimed water to make artificial snow. The current state of the San Francisco Peaks controversy would benefit from a decision-making process that holds sustainability policy at its core. The first step towards a new sustainability-focused deliberative process regarding a complex issue like the San Francisco Peaks controversy requires understanding the issue's origins and the perspectives of the people involved in the issue. My thesis provides an historical analysis of the controversy and examines some of the laws and participatory mechanisms that have shaped the decision-making procedures and power structures from the 19th century to the early 21st century.

Description
Over the past century in the southwestern United States human actions have altered hydrological processes that shape riparian ecosystems. One change, release of treated wastewater into waterways, has created perennial base flows and increased nutrient availability in ephemeral or intermittent channels. While there are benefits to utilizing treated wastewater for environmental flows, there are numerous unresolved ecohydrological issues regarding the efficacy of effluent to sustain groundwater-dependent riparian ecosystems. This research examined how nutrient-rich effluent, released into waterways with varying depths to groundwater, influences riparian plant community development. Statewide analysis of spatial and temporal patterns of effluent generation and release revealed that hydrogeomorphic setting significantly influences downstream riparian response. Approximately 70% of effluent released is into deep groundwater systems, which produced the lowest riparian development. A greenhouse study assessed how varying concentrations of nitrogen and phosphorus, emulating levels in effluent, influenced plant community response. With increasing nitrogen concentrations, vegetation emerging from riparian seed banks had greater biomass, reduced species richness, and greater abundance of nitrophilic species. The effluent-dominated Santa Cruz River in southern Arizona, with a shallow groundwater upper reach and deep groundwater lower reach, served as a study river while the San Pedro River provided a control. Analysis revealed that woody species richness and composition were similar between the two systems. Hydric pioneers (Populus fremontii, Salix gooddingii) were dominant at perennial sites on both rivers. Nitrophilic species (Conium maculatum, Polygonum lapathifolium) dominated herbaceous plant communities and plant heights were greatest in effluent-dominated reaches. Riparian vegetation declined with increasing downstream distance in the upper Santa Cruz, while patterns in the lower Santa Cruz were confounded by additional downstream agricultural input and a channelized floodplain. There were distinct longitudinal and lateral shifts toward more xeric species with increasing downstream distance and increasing lateral distance from the low-flow channel. Patterns in the upper and lower Santa Cruz reaches indicate that water availability drives riparian vegetation outcomes below treatment facilities. Ultimately, this research informs decision processes and increases adaptive capacity for water resources policy and management through the integration of ecological data in decision frameworks regarding the release of effluent for environmental flows.

Description
Driven by concern over environmental, economic and social problems, small, place based communities are engaging in processes of transition to become more sustainable. These communities may be viewed as innovative front runners of a transition to a more sustainable society in general, each one, an experiment in social transformation. These experiments present learning opportunities to build robust theories of community transition and to create specific, actionable knowledge to improve, replicate, and accelerate transitions in real communities. Yet to date, there is very little empirical research into the community transition phenomenon. This thesis empirically develops an analytical framework and method for the purpose of researching community transition processes, the ultimate goal of which is to arrive at a practice of evidence based transitions. A multiple case study approach was used to investigate three community transitions while simultaneously developing the framework and method in an iterative fashion. The case studies selected were Ashton Hayes, a small English village, BedZED, an urban housing complex in London, and Forres, a small Scottish town. Each community was visited and data collected by interview and document analysis. The research design brings together elements of process tracing, transformative planning and governance, sustainability assessment, transition path analysis and transition management within a multiple case study envelope. While some preliminary insights are gained into community transitions based on the three cases the main contribution of this thesis is in the creation of the research framework and method. The general framework and method developed has potential for standardizing and synthesizing research of community transition processes leading to both theoretical and practical knowledge that allows sustainability transition to be approached with confidence and not just hope.

Description
Geology and its tangential studies, collectively known and referred to in this thesis as geosciences, have been paramount to the transformation and advancement of society, fundamentally changing the way we view, interact and live with the surrounding natural and built environment. It is important to recognize the value and importance of this interdisciplinary scientific field while reconciling its ties to imperial and colonizing extractive systems which have led to harmful and invasive endeavors. This intersection among geosciences, (environmental) justice studies, and decolonization is intended to promote inclusive pedagogical models through just and equitable methodologies and frameworks as to prevent further injustices and promote recognition and healing of old wounds. By utilizing decolonial frameworks and highlighting the voices of peoples from colonized and exploited landscapes, this annotated syllabus tackles the issues previously described while proposing solutions involving place-based education and the recentering of land within geoscience pedagogical models.

ABSTRACT
This study of the policies of the U.S. public school system focuses on state and federal funding to examine how budget cuts, the teacher shortage crisis, and large classroom sizes are interrelated. A qualitative method of approaching these issues and a meta-analysis of the findings, combined with my personal experience as a high school English teacher in the public school system points to a ripple effect where one problem is the result of the one before it. Solutions suggested in this study are made with the intention to support all U.S. public school students with an emphasis on students with special needs, English language learners, and students from low-income families. My findings show that marginalized students in U.S. public schools are experiencing a form of education injustice. This study highlights the burden placed upon the states to fund education and asserts that qualified professionals are increasingly difficult to recruit while teacher attrition rates continue to grow. The changing teacher-to-student ratio means students enjoy one-on-on time with teachers less often due to overcrowded classrooms. The interrelationship of these issues requires a multifaceted approach to solving them, beginning with a demand for more federal funding which will allow previously cut programs to be reinstated, incentives to recruit and retain highly qualified teachers which will reduce classroom sizes, and implementation of new programs targeted to ensure the success of students with special needs, English language learners, and students from low-income families.

Description
This project seeks to explore how organizations work toward refugee and immigrant integration through forming different types of coalitions and strategic networks. Semi-structured interviews were conducted to identify when coalitions emerge between refugee organizations and immigrant rights groups in order to examine their development, from how the coalitions broadly conceive of refugee and immigrant rights, to how they organize resources and information sharing, service provision, policy advocacy, and policy implementation. The project is guided by the question: What explains the formation of coalitions that advocate for both immigrant rights and refugee rights? Through examining the formation and development of these coalitions, this thesis engages at the intersections of immigration federalism, refugee studies and human rights scholarship to reveal deeper complexities in the politics of immigrant integration. The project sharpens these three scholarly intersections by three multi-level jurisdictions – California and Arizona in the United States and Athens in Greece – and by employing comparative analysis to unpack how national governments and federalism dynamics shape coalition building around immigrant integration.

Description
The thesis for this study is that structural racism within the U.S. criminal system causes Black mothers to assume the emotional work of caring for incarcerated sons. This project was designed using an interpretive approach that employed a combination of qualitative and auto-ethnographic methods, drawing on grounded theory principle. Six interviews were conducted with mothers in order to gain in-depth insight into their lived experiences. An auto-ethnographic method was used to analyze the author’s own personal experiences as a family member of the incarcerated in dialogue with the experiences of the broader research population. Studies on the key finding of the psycho-social impacts on mothers with incarcerated sons have explored the relationship between the mental depression of mothers and their son’s incarceration. They have found that financial challenges, dwindling social connections, lousy parenting evaluations, as well as the burden of care of the grandchildren of the incarcerated sons are some of the mediating factors of this relationship. A second key finding also showed that incarceration have had social-economic effects on the prisoner’s families. These families experience extreme financial hardship as a result of incarcerated loved ones. Another finding showed the unique coping strategies for mothers included assuming care taking responsibility, maintaining family relationships, and budget control. Finally, this study found that there are challenges to re-entry experienced by mothers with incarcerated sons when their released. Research findings and original contribution to scholarly knowledge uncovered that Black mothers of the incarcerated in addition to working the Second Shift, are experiencing the phenomena of what is coined to be the “Third Shift.”

Description
Small-scale, peasant farmers are some of the most vulnerable people to the effects of climate change. They rely on a stable climate to support their natural ways of farming, which typically depends on consistent rainfall, temperate weather, and predictable season cycles. The perceptions of how successful coffee production is during shifting climatic disruptions is of key importance, if mitigation or adaptation efforts are to be successfully implemented. By using ethnographic methods with members of a coffee cooperative in Mexico, called Cafe Justo, I found that peasant farmers are very perceptive of the climatic changes and recognize forthcoming challenges as a result of changes in weather and precipitation levels. Rain-fed agriculture remains particularly vulnerable to coffee market demands, as coffee production for the majority of the cooperative members is the primary source of income. Through interpretive analysis of in-depth interview data collected from 19 coffee-famers in Chiapas, Mexico, I identified factors associated with perceptions of changing climate and weather conditions. Social identities, general perceptions of climate change, and impacts on livelihoods were investigated through the speaking-with model, as it was presented by Nagar and Geiger in 2007. These findings have rich implications for co-learning between the small-scale, coffee farmers and the scientific community so that mitigation and adaptation strategies are discussed. The findings also merit further investigation into future migration changes due to mass exoduses of climate refugees who are no longer able to successfully cultivate and harvest the lands to serve their needs and those of their community.

Description
Accurately predicting local ranges of isotopic signatures in human populations is essential for answering questions about past migrations and mobility. While local ranges of δ18O can be estimated using modern baseline samples and precipitation models, there are many environmental and anthropogenic drivers that can cause these ranges to deviate from the ranges seen in human populations. This study performs a geostatistical meta-analysis on a large dataset (n = 1,370) of spatially contextualized archaeological δ18O samples from 30 publications in order to generate a predictive model of local human δ18O ranges in the Central Andes. Two models were generated, one using archaeological samples of both humans and fauna, and the other using only humans. The model using only human samples makes more accurate predictions, cautioning against the incorporation of faunal δ18O samples in studies of human provenance. The models are also compared against a model of δ18O values found in precipitation across the study area, and significant differences lead to the conclusion that precipitation models are insufficient for predicting local human δ18O ranges.
