Description
Desert ecosystems are one of the fastest urbanizing areas on the planet. This rapid shift has the potential to alter the abundances and species richness of herbivore and plant communities. Herbivores, for example, are expected to be more abundant in urban desert remnant parks located within cities due to anthropogenic activities that concentrate food resources and reduce native predator populations. Despite this assumption, previous research conducted around Phoenix has shown that top-down herbivory led to equally reduced plant biomass. It is unclear if this insignificant difference in herbivory at rural and urban sites is due to unaltered desert herbivore populations or altered activity levels that counteract abundance differences. Vertebrate herbivore populations were surveyed at four sites inside and four sites outside of the core of Phoenix during fall 2014 and spring 2015 in order to determine whether abundances and richness differ significantly between urban and rural sites. In order to survey species composition and abundance at these sites, 100 Sherman traps and 8 larger wire traps that are designed to attract and capture small vertebrates such as mice, rats, and squirrels, were set at each site for two consecutive trap nights. Results suggest that the commonly assumed effect of urbanization on herbivore abundances does not apply to small rodent herbivore populations in a desert city, as overall small rodent abundances were statistically similar regardless of location. Though a significant difference was not found for species richness, a significant difference between small rodent genera richness at these sites was observed.

Description
The Colorado River is the lifeblood for seven Basin States including Colorado, Utah, Wyoming, New Mexico, Arizona, California and Nevada. This water source aided westward expansion and allowed the arid Southwest to grow. Today, the river is over-allocated resulting in reduced flows. This could lead to water challenges in Arizona and the other Basin states. This river is the single largest entity from which Arizona receives water. Despite this, Arizona is still better situated for water cutbacks than other states like California. Arizona has more than nine million acre-feet of banked underground water and access to other water sources including the Salt and Verde rivers. Government officials are making decisions now that will affect water usage in Arizona for decades and generations to come. Digital media, such as iPad magazines are a good way to reach this technologically savvy generation and engage them concerning important issues. Designing for digital platforms presents unique opportunities. This platform requires solid content and visually appealing design to attract a Millennial audience born between the years 1981 and 1996, according to Pew Research Center. Digital magazines currently present a small segment of the media market, however this segment is growing exponentially. A study by Pew Research Center reports that this slice of the population is interested in consuming the news and emerging technologies such as digital magazines. These are good ways to reach and interest a digitally engaged readership. Reaching this age group is important because the Millennial generation will need to determine the future of the Colorado River and water use in Arizona. To ensure the future of water in the West, this generation needs to "learn about the reality of our water supply, what our real water challenges are and then get engaged and have a voice in what we do about our water planning for the future" (Porter, 2015). DISCLAIMER: The digital magazine was created in InDesign with interactive PDFs, which are best viewed on tablets. Screenshots of the magazine are included to demonstrate the magazine.

Description
In Arizona's early history, Females garnered more independence than most other women in the United States because they were forced to build a completely new life in settlements with little to no infrastructure. Now, Arizona has achieved a level of equality that no other state has yet to achieve in regard to gender representation. Yet, we have yet to achieve total equity. This paper looks to analyze responses that female senators from the Arizona State Legislature gave while being interviewed by the author. With questions derived from previous research conducted on women in politics at the state and federal level, this paper will delve into the personal experiences of six female senators. Although their personal narratives differ, their stories seem to reflect a collective tie that unites the female members together, beyond party allegiance. Each of the responses given by the senators had some aspects that showed trends supporting the majority of the hypotheses. Moving forward, in order to achieve 50% equality, two more senators would need to be elected and replace male senators.

Description
As Arizona enters its fifteenth year of drought and Lake Mead hits historic lows, water management and policy planning will become increasingly important to ensure future water security in the Southwestern region of the United States. This thesis compares water demand trends and policies at the municipal level in Phoenix and Tucson, Arizona over the time period from 1980-2010. By analyzing gallons per capita per day (GPCD) trends for each city in the context of population growth, drought, and major state and local policies over the twenty year period, reasons for declines in per capita water demand were explored. Despite differences in their available water sources and political cultures, both the City of Phoenix and the City of Tucson have successfully reduced their per capita water consumption levels between 1980 and 2010. However, this study suggests that each city's measured success at reducing GPCD has been more a result of external events (supply augmentation, drought, and differing development trends) rather than conservation and demand reduction regulations adopted under the auspices of the Groundwater Management Act.

Description
Each year the United States' interstates and roadways become increasingly congested, with little development of useful mass transit. Elon Musk released a whitepaper titled Hyperloop Alpha in order to generate conversation around a potential "fifth mode of transportation" as an alternative to current high-speed rail technologies. This case study analyzes the implications of implementing the Hyperloop along the 120-mile Phoenix-Tucson route in terms of the State's geographic, economic, political, and environmental advantages for the Hyperloop design. This case study was not meant to investigate the engineering aspects of an untested technology, but rather to generate conversation and elicit enthusiasm in the State of Arizona in order to bring the project in-house. Through comparison of the California context of the Hyperloop and other megaregions this report proposes that given Arizona's solar power production potential, short, flat, undeveloped route, explosive population growth, urban density distribution, recognized need for HSR, and strong research institutions make it the ideal site and premiere candidate for initial Hyperloop testing and construction.

Description
Dual Language Immersion programs have been growing exponentially as a result of an urgent need for globally competent, bilingual or multilingual citizens. The US is currently facing a language deficit, which negatively affects national security, international relations and even the economy. If America wants to stay in contention as one of the strongest world powers, the US needs to foster more interest in learning foreign languages earlier and invest in the development of foreign language education. The purpose of this paper is to provide an overview of the history and implementation of different Dual Language Immersion program models. The geographical scope of the paper will cover historical background in Canada and the current implementation of Dual Language Immersion models in three Southwestern states: California, Utah and Arizona. The paper also outlines challenges related to the implementation of these dual language immersion programs.

Description
This creative project is a collection of profiles focused on Arizona nonprofits and refugees. The profiles share stories of refugees, volunteers, employees and others involved in the community serving refugees. Nonprofits are a vital resource for refugee resettlement. These organizations offer services to support refugees as they transition into new communities. Some services include: housing, English language learning, cultural orientation, job placement, medical treatment, education, and farming. Each of these programs support resiliency for refugees and for the communities in which they live. We Are Resilient was created first, to show the important role nonprofits have in serving refugees. Second, to connect people to a few of the stories and experiences within the Arizona refugee community. And third, to build understanding of the strength refugees bring to communities of Arizona and by extension the country. Visit weareresilientaz.com to learn more.

Description
The objective of the research was to simulate interdependencies between municipal water-power distribution systems in a theoretical section of the Phoenix urban environment that had variable population density and highest ambient temperature. Real-time simulations were run using the Resilient Infrastructure Simulation Environment (RISE) software developed by Laboratory for Energy and Power Solutions (LEAPS) at ASU. The simulations were run at estimated population density to simulate urbanism, and temperature conditions to simulate increased urban heat island effect of Phoenix at 2020, 2040, 2060, and 2080 using the IEEE 13 bus test case were developed. The water model was simulated by extrapolated projections of increased population from the city of Phoenix census data. The goal of the simulations was that they could be used to observe the critical combination of system factors that lead to cascading failures and overloads across the interconnected system. Furthermore, a Resilient Infrastructure Simulation Environment (RISE) user manual was developed and contains an introduction to RISE and how it works, 2 chapters detailing the components of power and water systems, respectively, and a final section describing the RISE GUI as a user. The user manual allows prospective users, such as utility operators or other stakeholders, to familiarize themselves with both systems and explore consequences of altering system properties in RISE by themselves. Parts of the RISE User Manual were used in the online "help" guide on the RISE webpage.

Description
Current literature on sustainability education and its core competencies (systems thinking, normative, interpersonal, strategic, and future thinking) has yet to acknowledge the K-12 level, concentrating instead on higher-level institutions. To initiate study at the critical K-12 level, a curriculum module composed of four lessons to address the wicked sustainability problem of drought in the Sonoran Desert was developed, piloted, and evaluated. The framework of each lesson combined the core competencies and the 5Es pedagogy (engage, explore, explain, elaborate, and evaluate). Two lessons were successfully piloted in two seventh grade middle-school science classes in Phoenix, Arizona. Topics addressed were the water cycle, types of drought, water systems, and mitigation methods. Evaluation determined a high level of student engagement. Post-pilot teacher questionnaires revealed a high degree of support for inclusion of sustainability education and core competencies addressing drought in future opportunities. It is concluded that lessons in the future can adopt the core competences of sustainability with the support of educators in Arizona.

Description
Urban Heat Island (UHI) is considered as one of the major problems in the 21st century posed to human beings as a result of urbanization and industrialization of human civilization. The large amount of heat generated from urban structures, as they consume and re-radiate solar radiations, and from the anthropogenic heat sources are the main causes of UHI. The two heat sources increase the temperatures of an urban area as compared to its surroundings, which is known as Urban Heat Island Intensity (UHII). The problem is even worse in cities or metropolises with large population and extensive economic activities. The estimated three billion people living in the urban areas in the world are directly exposed to the problem, which will be increased significantly in the near future. Due to the severity of the problem, vast research effort has been dedicated and a wide range of literature is available for the subject. The literature available in this area includes the latest research approaches, concepts, methodologies, latest investigation tools and mitigation measures. This study was carried out to review and summarize this research area through an investigation of the most important feature of UHI. It was concluded that the heat re-radiated by the urban structures plays the most important role which should be investigated in details to study urban heating especially the UHI. It was also concluded that the future research should be focused on design and planning parameters for reducing the effects of urban heat island and ultimately living in a better environment.
