Space-based solar power is a renewable energy that is an alternative to all other forms of energy production. It takes on a new approach that pushes energy production off-world. Energy is harnessed and beamed down to a ground receiver via microwaves which is then sent to the grid and distributed to people across the country, and even globe. While the technology is new and still in the research and development stages, the ability is there. An economic analysis of the various technology yields levelized costs of energy comparable to current prices—under $.10/kWh. The markets and profits for this type of technology are abundant, ranging from commercial to military uses, with profits in the millions to billions of dollars. The environmental impacts are low compared to current energy production methods. The potential is great, the technology is close, and the future is near.

Denver, Colorado is experiencing an unprecedented growth spurt, particularly in the downtown neighborhoods. As such, the city has proposed a multitude of urban revitalization projects in its urban core. This pattern of revitalization has unintended consequences including changes in residents’ meanings assigned to their neighborhoods and subsequently changes in residents’ attachment to those neighborhoods. Given this, the purpose of this phenomenological study was to use a symbolic interactionist perspective to uncover resident meanings of their neighborhoods and discover how redevelopment efforts are affecting those assigned meanings. Participants, recruited through the snowball sampling method in the Globeville and Elyria-Swansea neighborhoods in downtown Denver, were interviewed during spring of 2017. Photo-elicitation techniques were used as part of the interviews. Additionally, secondary data available through public documents were analyzed to provide a context for understanding the changes that are taking place in the selected neighborhoods. This data aids in guiding future research, which may ultimately better inform the government agencies and private organizations who are looking to redevelop low-income neighborhoods similar to the Globeville and Elyria-Swansea neighborhoods in the given study.

This thesis, done in a capstone course through the Arizona State University School of Sustainability, examines the current state of sustainability-related processes at all of Major League Baseball's Cactus League sites, with a focus on Salt River Fields. Through this close examination, a final report created of our findings and suggestions were presented to executives from Major League Baseball and the two occupants of Salt River Fields: the Arizona Diamondbacks and the Colorado Rockies. The overall goal is to add value to Cactus League stadiums, clubs, and the fans while promoting sustainable initiatives and creating lasting change. With a team of 11 undergraduate and graduate students from ASU led by Colin Tetreault, research was conducted by examining similar efforts by major sports leagues and comparable organizations. Our team researched reports from organizations such as the National Hockey League to determine how we could implement our ideas on a large scale successfully. Determining that fan engagement is crucial to changing the culture and implementation of sustainability, we also researched ways to interact with fans on social media and cooperated with the social media teams from the Arizona Diamondbacks and the Colorado Rockies. Additionally, we visited every stadium in the Cactus League and met with representatives from each team to determine what sort of processes they have in place, if they have any suggestions or thoughts for our efforts, and we gave each of them advice as consultants. At each site, we also interviewed vendors, cleaning crews, and fans for more information. At Salt River Fields, we engaged the guest service attendants, social media team, vendors, the Jani King custodial team, and staff involved with operations for information and to suggest changes. We started a new initiative in cooperation with these entities known as the "Recycle Rally" where we engaged with fans about recycling information and collected their recyclables. Additionally, we surveyed fans on their personal views on sustainability at each game we attended. We also conducted two waste audits at Salt River Fields, where we examined a large sample size of waste, sorted all of it into categories, and weighed it on a scale to determine how much of each category of waste there was. This data was later plotted and analyzed.

This thesis examines how the wording of proposed government policies can affect the level of public support that a given policy generates. By surveying 158 Phoenix residents, I tested the differing degrees of support that voters would have for a proposed city ordinance, which would stop Homeowners' Associations from restricting the use of native desert plants in residential landscaping. The ordinance was framed in the survey as a self-governance issue or a water conservation issue. I found that the message frames had little effect on the overall level of support for the ordinance, since most residents had moderate support for the policy. However, participants who were either residents of Homeowners' Associations that did not have native plant restrictions, or native residents of Arizona, demonstrated greater levels of support for the self-determination frame of the proposed ordinance. These findings have implications for policy makers who use targeted messages to establish pro-environmental policies at the local level.

Many scholars agree that heritage tourism has grown in recent years. It has become a unique way for communities to diversify their economies while preserving local culture and heritage. One unique way communities are doing this is through heritage festivals. These festivals have a significant impact on local communities and are multifaceted as they do not just provide economic impact to host communities, but also positive or potentially negative social and environmental impacts.

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.

This study was designed to influence consumer habits, specifically those relating to purchases of fruits, vegetables, and junk food. Previous studies have clearly shown the ineffectiveness of simply describing the health benefits of eating more fruits and vegetables (F/V). In contrast, this study aimed to change the result by changing the message: providing participants with insight into the hidden agendas of food companies and grocery stores, provide useful tips on how to include children when selecting F/V, and emphasizing the importance of parental modeling in regard to food purchases. Participants of this study were separated into two groups, the tour group and the education group. The tour group was guided through a grocery store where they learned about sales tactics and manipulations used by grocery stores and food companies to influence purchases. Education group participants were provided with an education session focusing on USDA and FDA handouts displaying current educational suggestions for increasing F/V consumption. Grocery store receipts were collected and analyzed to track the progress of both groups. The goal of the study was to identify a method of informing consumers that will produce a significant change in behavior. Increasing F/V consumption, even in relatively small amounts, would be an important step forward in improving the diet and overall health of Americans. This study was the first of its kind to measure purchasing patterns objectively (through analysis of purchase receipts, rather than personal opinion/evaluation surveys) and in a wide-scope retail environment that includes all grocery store purchases by participants. Significant increases or decreases in the amount of money spent on F/V, or the amount (pounds) of F/V purchased were not seen, however a small correlation (r = 0.133) exists when comparing the weight of F/V purchased pre/post intervention. Data from Food Frequency Questionnaires shows participants consuming significantly higher amounts of F/V post intervention (p=0.043). The tour group and education group experienced an average increase of 0.7 servings per day. Future interventions might benefit by extending their scope to include cooking demonstrations, in-home interventions, and education on healthy eating outside of the home.
