City managers and policy makers are increasing looking to environmental systems to provide beneficial services for urban systems. Constructed wetland systems (CWS), highly managed and designed wetland ecosystems, are being utilized to remove pollution, particularly excess nitrogen (N), from treated wastewater. Various wetland process remove N from effluent, such as denitrification, direct plant uptake, and soil accumulation. Emergent macrophytes provide direct uptake of N and improve conditions for microbially-mediated N processing. The role of different macrophytes species, however, is less understood and has primarily been examined in mesocosm and microcosm experiments and in mesic environments. I examined the effects of community composition on N removal and processing at the whole ecosystem scale in an aridland, constructed wetland (42 ha) through: 1) quantifying above- and belowground biomass and community composition from July 2011 \u2014 November 2012 using a non-destructive allometric technique, and; 2) quantifying macrophyte N content and direct macrophyte N uptake over the 2012 growing season. Average peak biomass in July 2011 & 2012 was 2,930 g dw/m2 and 2,340 g dw/m2, respectively. Typha spp. (Typha domingensis and Typha latifolia) comprised the majority (approximately 2/3) of live aboveground biomass throughout the sampling period. No statistically significant differences were observed in macrophyte N content among the six species present, with an overall average of 1.68% N in aboveground tissues and 1.29% N in belowground tissues. Per unit area of wetland, Typha spp. retained the most N (22 g/m2); total N retained by all species was 34 g/m2. System-wide direct plant N uptake was markedly lower than N input to the system and thus represented a small portion of system N processing. Soil accumulation of N also played a minor role, leaving denitrification as the likely process responsible for the majority of system N processing. Based on a literature review, macrophyte species composition likely influences denitrification through oxygen diffusion into soils and through the quality and quantity of carbon in leaf litter. While this study and the literature indicates Typha spp. may be the best species to promote wetland N processing, other considerations (e.g., bird habitat) and conditions (e.g., type of wastewater being treated) likely make mixed stands of macrophytes preferable in many applications. Additionally, this study demonstrated the importance of urban wetlands as scientific laboratories for scientists of all ages and as excellent stepping-off points for experiments of science-policy discourse.

Brundtland’s definition of sustainability is the ability to “meet the needs of the present without compromising the ability of future generations to meet their needs” (IISD, 2021). But what if there are no future generations? Social sustainability, the sector of sustainability that foregrounds the well-being and livelihoods of people (and thereby continuation of humanity), is included in definitions within the sustainability field, but less developed in sustainability practice. In an effort to bridge this gap of knowledge, 14 U.S. cities and over 100 sustainability policies were analyzed for their social sustainability performance. An eight-item analytical framework that deals with differing areas of social equity guided the analysis. Results found that most cities’ sustainability departments fell short of truly addressing social sustainability concerns. Out of the eight items, the most frequently addressed were housing security and racial and gender equality whereas few, if any, cities addressed the more specific social concerns of immigration, technology and media, or arts/cultural preservation. Future research is recommended to gain a better understanding of the ways existing cities can improve in this area.

This paper conducts an exploration of the election policy reaction to the COVID-19 pandemic within the United States. While living through and voting during the real-time events which took place during the COVID-19 Pandemic of 2020, it soon became evident that there was not enough experience from earlier election emergencies to properly ensure against voter disenfranchisement. Given the scope of the global pandemic and the speed with which policymakers had to act, there was very little time to properly prepare. There was also great contention regarding the legitimacy of election methods proposed to alleviate in-person election concerns, such as mail-in voting. The political battle between those who believed COVID-19 to be a grave concern against those who did not consider COVID-19 to be a legitimate threat towards their livelihoods also affected policymaking decisions. Policymakers were forced into a corner, as they experienced criticism for not enough government action, as well as disapproval on the actual regulation that came to pass. This paper therefore aims to understand what factors led to the decisions which shaped the election policy which occurred as a reaction to the COVID-19 pandemic during the election year of 2020. This analysis is conducted by considering the following: prior election emergency policy; the development of reactive election policy in March, proactive policy established for the August and November elections; and a review of voter disenfranchisement which occurred due to COVID-19.

This paper argues that improved student disability services at universities can limit the amount of stress that burdens students with disabilities in order to, improve their mood and create greater possibilities for successful student outcomes. This study begins by reviewing the progress that has been made in the 20th and 21st centuries in terms of heightened awareness and legislation that benefit people with disabilities. In addition, it applauds the efforts made so far at the Arizona State University Polytechnic and Tempe campuses, but also seeks to highlight some concerns that might become a focus of future policymaking endeavors. The applause and concerns are based on the experience of the author with ASU’s Disability Resource Center (DRC), now rebranded as the Student Accessibility and Inclusive Learning Services (SAILS). The author’s lens of physical/mobility limitations yields insight into the accessibility of the unique programs
offered by ASU’s Study Abroad Office as well as the daily transportation efforts of the DRC/SAILS’s DART service. The particular experiences discussed include a Barrett Global Intensive Experience trip to Ireland, the use of the on-campus DART transportation service at Polytechnic and Tempe, handicap parking and elevator placement at Polytechnic, the intercampus shuttle, and the future of Zoom as a means of providing accessibility to students with disabilities. This paper will make recommendations to the appropriate parties for possible changes to policy and/or procedure and alterations to the current state of tangible obstacles.

The African Continental Free Trade Agreement is one of the latest developments in the world of African politics. It influences several key policy arenas, including the focus of this paper: developmental policy. The AfCFTA hopes to integrate the intra-African trading system, as well as implement several measures to integrate their entire economies. This paper examines the intersection between the AfCFTA and developmental policy defining how it helps and hinders African development goals. This thesis intends to give a clear picture of how this agreement coincides with developmental policy through both economic and political research. The goal of this paper is to provide readers with a detailed report on how this economic agreement could be shaping the developmental policy of the African world.

This thesis examines the current state of intervention in developing countries that are suffering from human rights abuses, mass killings, and/or politicide. The first part of this thesis will be a brief examination of present-day United States intervention efforts in order to understand the decision making and reconstruction process within the status quo. This will also be done by looking at the global community´s preferred form of intervention and how the United States aligns with these standards such as those represented in the Responsibility to Protect. Secondly, this thesis aims to remodel the reconstruction process in order to conceptualize the addition of mental health first aid. This will be presented by first analyzing the importance of mental health aid and then looking at the specific diagnoses that concatenate with trauma. This thesis argues that current reconstruction efforts are insufficient without the implementation of psychological aid. Without adding psychological aid, countries are more likely to return to cycles of violence that were present pre-intervention. Public policy should change to include aiding civilians, not only physically, economically, or militarily, but also by including psychological aid. Implementing behavior health specific aid in developing countries may potentially be the missing component to lasting change that countries need in order to sustain political sovereignty and support community efforts to rebuild. This research, therefore, aims to bridge important gaps between United States intervention efforts, public policy and mental health.

This thesis investigates the policy surrounding English Language Learners (ELL) on both a federal and state level, with an emphasis on the state of Arizona. Arizona ELL policy and pedagogy have been the subjects of research nationwide; many studies demonstrate that ELLs struggle before, during and after participating in Arizona ELL programs (Lillie et al. 2012; Roa 2012; Office of Civil Rights 2012). Despite this previous research there were limited comprehensive overviews of the data that had been collected as well as recommendations that could be created utilizing the data. This thesis addresses that void of information through 1) A comprehensive literature review of the framework of policies used on the federal and state level, and 2) recommendations provided that are based on the findings of the literature included in the review. Study findings present that there is limited literature to support the English-Only policies currently enforced in the state of Arizona and that students would be better served to utilize other language acquisition approaches that view their primary language as a resource rather than a problem. Additionally, the literature suggests that there needs to be greater oversight in what language is being used to define certain groups so that all students receive proper resources and that there needs to be more communication about federal and state guidelines currently in place. It was recommended that extended research be conducted given recent policy shifts in the state of Arizona that occurred while the thesis was written, that future policy should account for greater inclusivity as well as continuous support, and that the state of Arizona reframe most of its current policies to be more fully aligned with research-based strategies.

The rise in urban populations is encouraging cities to pursue sustainable water treatment services implementing constructed treatment wetlands (CTW). This is especially important in arid climates where water resources are scarce; however, research regarding aridland CTWs is limited. The Tres Rios CTW in Phoenix, Arizona, USA, presents the tradeoff between greater water loss and enhanced nitrogen (N) removal. Previous research has suggested that water loss due to transpiration is replaced by a phenomenon termed the Biological Tide. This trend has been documented since 2011 by combining transpiration values with a nitrogen budget. Calculations were made at both the marsh and whole-system scale. The purpose of this paper is to demonstrate how the Biological Tide enhances N uptake throughout the CTW. Results indicate that about half of the nitrogen taken up by the vegetated marsh is associated with new water entering the marsh via the Biological Tide with even higher values during warmer months. Furthermore, it is this phenomenon that enhances N uptake throughout the year, on average, by 25.9% for nitrite, 9.54% for nitrate, and 4.84% for ammonium at the whole-system scale and 95.5%, 147%, and 118% within the marsh. This paper demonstrates the Biological Tide’s significant impact on enhanced N removal in an aridland CTW.

A comprehensive review of the managed retreat literature reveals mixed feelings towards the legality, practicality and cost of the policy action as a way to react to rising sea level and coastal erosion. Existing research shows increasing costs of severe storm damage borne to insurance companies and private citizens, furthering the need for long-term policy actions that mitigate the negative effects of major storms. Some main policy actions are restricting development, strategically abandoning infrastructure, funding buyout programs, utilizing rolling easements, and implementing a variety of protective structures. These policy actions face various problems regarding their feasibility and practicality as policy tools, including wavering public support and total costs associated with the actions. Managed retreat specifically faces public scrutiny, as many coastal property owners are reluctant to retreat from the shore. This paper will use examples of managed retreat in other countries (Netherlands, Belgium, and France) to develop plans for specific municipalities, using their models, costs and successes to generate in-depth policy plans and proposals. When observing Clatsop County, Oregon and assessing its policy options, its established that the best policy option is a combination of beach nourishment and Controlled Reduced Tides. This paper analyzes several features of the county, such as the importance of its coastal economic activity and its geographical makeup, to decide what policy actions would be best to mitigate its risk from sea level rise and flood damages. The process used to determine the best course of action for Clatsop County can be replicated in other municipalities, although the resulting policies will obviously be unique to the area.
