Description
There has been a push to create and implement school wellness policies. Childhood obesity statistics suggest that schools may have an important role to play in promoting wellness. Childhood obesity has become a significant problem in the United States. The percentage of obese children in the United States has more than doubled since 1970, and up to 33% of the children in the United States are currently overweight. Among the 33% of children who are overweight, 25% are obese, and 14% have type 2 diabetes, previously considered to be a condition found only in adults. This mixed-method study with a string qualitative component study examined three aspects of federally mandated local wellness polices. The study investigated the policies themselves, how the policies are understood in the local school setting, with a particular focus on the impact the policies have had on school meals. The bulk of the research data was generated through 8 in-depth interviews. The interviews were conducted with key stakeholders within 2 elementary school districts in Arizona. In addition, the evaluation of 20 local wellness polices was conducted via a rubric scoring system. The primary component found to be lacking in local wellness policies was the evaluation method. Recommendations for school districts include the establishment of a clear method of measurement.

Description
This thesis explores the implications that the outcome of a certain U.S. lawsuit involving antiquities could have on practices and programs in the United States, related to cultural heritage and history. This paper examines the Rubin et al case, which sought to attach a collection of ancient Persian artifacts (known as The Persepolis Tablets) as a source of legal compensation. Presented as a case study, and using primary and secondary research sources, this paper analyzes the Rubin et al lawsuit and the factors that led to its initiation, and seeks to determine how and why adverse consequences could result from its final ruling. This thesis demonstrates that the final decision in the lawsuit could leave a negative impact on a number of practices related to cultural heritage in the United States, especially with regards to cultural and academic institutions such as museums and universities.

Description
This descriptive qualitative case study explored undergraduate degree attainment by African American males in football and basketball at a National Collegiate Athletic Association (NCAA) Division I institution in the Southwest. Semi-structured interviews were conducted with four participants at the institution to uncover experiences that helped or hindered their progress toward degree completion. Student perceptions of their environment, the role of athletics in determining future goals, and the role of the athletic institution and its constituent members in promoting or deterring degree completion is explored. Student aspiration to attain a degree, expectations for job prospects and financial opportunity after college is also discussed. Contextual and perceptual elements emerged as salient attributes in their experiences as students and athletes. The study results are consistent with previous findings linking academic engagement and motivation, to family and environment.

Description
The Committee on Rare and Endangered Wildlife Species (CREWS) of the U.S. Fish and Wildlife Service (FWS) made important and lasting contributions to one of the most significant pieces of environmental legislation in U.S. history: the Endangered Species Act of 1973 (ESA). CREWS was a prominent science-advisory body within the U.S. Department of the Interior (DOI) in the 1960s and 1970s, responsible for advising on the development of federal endangered-wildlife policy. The Committee took full advantage of its scientific and political authority by identifying a particular object of conservation--used in the development of the first U.S. list of endangered species--and establishing captive breeding as a primary conservation practice, both of which were written into the ESA and are employed in endangered-species listing and recovery to this day. Despite these important contributions to federal endangered-species practice and policy, CREWS has received little attention from historians of science or policy scholars. This dissertation is an empirical history of CREWS that draws on primary sources from the Smithsonian Institution (SI) Archives and a detailed analysis of the U.S. congressional record. The SI sources (including the records of the Bird and Mammal Laboratory, an FWS staffed research group stationed at the Smithsonian Institution) reveal the technical and political details of CREWS's advisory work. The congressional record provides evidence showing significant contributions of CREWS and its advisors and supervisors to the legislative process that resulted in the inclusion of key CREWS-inspired concepts and practices in the ESA. The foundational concepts and practices of the CREWS's research program drew from a number of areas currently of interest to several sub-disciplines that investigate the complex relationship between science and society. Among them are migratory bird conservation, systematics inspired by the Evolutionary Synthesis, species-focused ecology, captive breeding, reintroduction, and species transplantation. The following pages describe the role played by CREWS in drawing these various threads together and codifying them as endangered-species policy in the ESA.

Description
Children with dis/abilities the world over are widely required to sacrifice their human rights to education, equity, community, and inclusion. Fewer than 10% of children with dis/abilities in developing countries attend school. Namibia, Africa, where this study took place, is no different. Despite Namibia's adoption of international covenants and educational policy initiatives, children with dis/abilities continue to be overwhelmingly excluded from school. The body of literature on exclusion in sub-Saharan Africa is laden with the voices of teachers, principals, government education officials, development organizations, and scholars. This study attempted to foreground the voices of rural Namibian families of children with dis/abilities as they described their lived experiences via phenomenological interviews. Their stories uncovered deeply held assumptions, or cultural models, about dis/abilities. Furthermore, the study examined how policy was appropriated by local actors as mediated by their shared cultural models. Ideas that had been so deeply internalized about dis/abilities emerged from the data that served to illustrate how othering, familial obligation, child protection, supernatural forces, and notions of dis/ability intersect to continue to deny children with dis/abilities full access to educational opportunities. Additionally, the study describes how these cultural models influenced cognition and actions of parents as they appropriated local educational policy vis-à-vis creation and implementation; thereby, leaving authorized education policy for children with dis/abilities essentially obsolete. The top down ways of researching by international organizations and local agencies plus the authorized policy implementation continued to contribute to the perpetuation of exclusion. This study uncovered a need to apply bottom up methods of understanding what parents and children with dis/abilities desire and find reasonable for education, as well as understanding the power parents wield in local policy appropriation.

Description
Many expect renewable energy technologies to play a leading role in a sustainable energy supply system and to aid the shift away from an over-reliance on traditional hydrocarbon resources in the next few decades. This dissertation develops environmental, policy and social models to help understand various aspects of photovoltaic (PV) technologies. The first part of this dissertation advances the life cycle assessment (LCA) of PV systems by expanding the boundary of included processes using hybrid LCA and accounting for the technology-driven dynamics of environmental impacts. Hybrid LCA extends the traditional method combining bottom-up process-sum and top-down economic input-output (EIO) approaches. The embodied energy and carbon of multi-crystalline silicon photovoltaic systems are assessed using hybrid LCA. From 2001 to 2010, the embodied energy and carbon fell substantially, indicating that technological progress is realizing reductions in environmental impacts in addition to lower module price. A variety of policies support renewable energy adoption, and it is critical to make them function cooperatively. To reveal the interrelationships among these policies, the second part of this dissertation proposes three tiers of policy architecture. This study develops a model to determine the specific subsidies required to support a Renewable Portfolio Standard (RPS) goal. The financial requirements are calculated (in two scenarios) and compared with predictable funds from public sources. A main result is that the expected investments to achieve the RPS goal far exceed the economic allocation for subsidy of distributed PV. Even with subsidies there are often challenges with social acceptance. The third part of this dissertation originally develops a fuzzy logic inference model to relate consumers' attitudes about the technology such as perceived cost, maintenance, and environmental concern to their adoption intention. Fuzzy logic inference model is a type of soft computing models. It has the advantage of dealing with imprecise and insufficient information and mimicking reasoning processes of human brains. This model is implemented in a case study of residential PV adoption using data through a survey of homeowners in Arizona. The output of this model is the purchasing probability of PV.

Description
Despite the urgent need to reduce global greenhouse gas emissions (GHGs), there has been a lack of national climate action leadership in the United States. In this vacuum, the need for subnational action, particularly at the local level, has become essential. But cities only have the authority granted them by their state. Thus, many cities thus take climate action consistent, or in-sync, with their state. However, other cities take climate action inconsistent, or out-of-sync, with their state. This study examines this in-sync, out-of-sync phenomenon using a multilevel, multiple case study approach to determine the multilevel dynamics influencing whether a city is taking climate action. The study compares two states at opposite ends of the climate mitigation spectrum—Idaho, a state not taking any mitigation action, and Washington, a state taking aggressive mitigation action—and two cities within each of these states, with one city in-sync and the other out-of-sync with its state on climate action. The results show ideology/political affiliation as the most significant factor influencing state and city climate policy: progressive leaning cities/state are engaging in climate mitigation action; conservative leaning cities/state are not. This result was expected, but the study revealed many nuances that were not. For example, the strength of a city’s ideological leaning can overcome disabling state authority. Ideological leaning impacts whether non-state actors are a driver or barrier to climate action. Policy experimentation is found only in progressive cities. Co-benefits manifest in different ways, depending on ideological leaning and whether a city is in- or out-of-sync. And policy champion influence can be fully realized only with supportive elected leadership.
This study highlights important interplays between drivers and barriers cities face in addressing climate change in a multilevel setting; how those interplays can help or hinder municipal climate action; and strategies cities employ to address challenges they face. The study findings thus contribute to the understanding of why and how cities take climate action, and how barriers to action can be overcome. This understanding is essential for providing a path forward on municipal climate action and accelerating the reduction of municipal GHG emissions.

Description
Despite increased attention and funding from companies and governments worldwide over the past several years, cybersecurity incidents (such as data breaches or exploited vulnerabilities) remain frequent, widespread, and severe. Policymakers in the United States have generally addressed these problems discretely, treating them as individual events rather than identifying commonalities between them and forming a more effective broad-scale solution. In other words: the standard approaches to cybersecurity issues at the U.S. federal level do not provide sufficient insight into fundamental system behavior to meaningfully solve these problems. To that end, this dissertation develops a sociotechnical analogy of a classical mechanics technique, a framework named the Socio-Technical Lagrangian (STL). First, existing socio/technical/political cybersecurity systems in the United States are analyzed, and a new taxonomy is created which can be used to identify impacts of cybersecurity events at different scales. This taxonomy was created by analyzing a vetted corpus of key cybersecurity incidents, each of which was noted for its importance by multiple respected sources, with federal-level policy implications in the U.S..
The new taxonomy is leveraged to create STL, an abstraction-level framework. The original Lagrangian process, from the physical sciences, generates a new coordinate system that is customized for a specific complex mechanical system. This method replaces a conventional reference frame –one that is ill-suited for the desired analysis –with one that provides clearer insights into fundamental system behaviors. Similarly, STL replaces conventional cybersecurity analysis with a more salient lens, providing insight into the incentive structures within cybersecurity systems, revealing often hidden conflicts and their effects. The result is not a single solution, but a new framework that allows several questions to be asked and answered more effectively.
Synthesizing the findings from the taxonomy and STL framework, the third contribution involves formulating reasonable and effective recommendations for enhancing the cybersecurity system's state for multiple stakeholder groups. Leveraging the contextually appropriate taxonomy and unique STL framework, these suggestions address the reform of U.S. federal cybersecurity policy, drawing insights from various governmental sources, case law, and discussions with policy experts, culminating in analysis and recommendations around the 2023 White House Cybersecurity Strategy.

Description
A group of educators and administrators in an international school in Thailand collaborated for a year to devise and publish a policy document with aim to reform assessment practices of its faculty. The group’s beliefs derived from standards-based assessment leaders and its broad aim was to build a more coherent, accurate, and meaningful assessment system. Using Actor Network Theory as its theoretical perspective, this mixed-methods action research study explored the extent that the policy document changed the beliefs and practices of the faculty, the assessment materials within the system itself, and what other factors may also help account for any changes. The first finding is that the policy did lead to observable changes in practices of faculty traced in tests, quizzes, and the gradebooks that record assessments. A second finding is that the impact of the policy as an agent for change depends on the frequency that it is referenced.

Description
Marine plastic pollution (MPP) has emerged as one of the most pressing global environmental challenges of the anthropocene. There has been an upsurge in investment to mitigate MPP; however, interventions can be costly, inequitable, and ineffective in achieving their objectives. In my dissertation, I aim to research key considerations for creating cost-effective, equitable mitigation strategies for MPP and its impacts to marine biodiversity and coastal communities. In chapter one, I introduce the challenges plastic pollution poses. In chapter two, I use seascape ecology theory to present the concept of the plastic-scape and describe how seascape ecology principles, methods, and approaches to transdisciplinary science can inform research to mitigate MPP. In chapter three, I present a framework to help decision makers estimate the total cost of MPP interventions and partial costs accrued by stakeholder groups. I then apply this framework to two quantitative case studies and four comparative case studies to exemplify its use and highlight the ways spatial scale, temporal scale, and socio-economic conditions influence the intervention cost and cost distribution. In chapter four, I employ a trait-based approach to produce a framework for developing indices of species vulnerability to macroplastic pollution. Finally, in chapter five, I implement the framework developed in the previous chapter and present a multi-taxonomic, macroplastic vulnerability index for three marine taxa—mammals, birds, and turtles—to identify the marine species most vulnerable to macroplastic pollution in Hawai‘i. Overall, my dissertation shows how policy-driven, systemic research of MPP and its interventions can improve efforts to address MPP and its socio-economic and ecological consequences.
