Description
In recent years we have witnessed a shift towards multi-processor system-on-chips (MPSoCs) to address the demands of embedded devices (such as cell phones, GPS devices, luxury car features, etc.). Highly optimized MPSoCs are well-suited to tackle the complex application demands desired by the end user customer. These MPSoCs incorporate a constellation of heterogeneous processing elements (PEs) (general purpose PEs and application-specific integrated circuits (ASICS)). A typical MPSoC will be composed of a application processor, such as an ARM Coretex-A9 with cache coherent memory hierarchy, and several application sub-systems. Each of these sub-systems are composed of highly optimized instruction processors, graphics/DSP processors, and custom hardware accelerators. Typically, these sub-systems utilize scratchpad memories (SPM) rather than support cache coherency. The overall architecture is an integration of the various sub-systems through a high bandwidth system-level interconnect (such as a Network-on-Chip (NoC)). The shift to MPSoCs has been fueled by three major factors: demand for high performance, the use of component libraries, and short design turn around time. As customers continue to desire more and more complex applications on their embedded devices the performance demand for these devices continues to increase. Designers have turned to using MPSoCs to address this demand. By using pre-made IP libraries designers can quickly piece together a MPSoC that will meet the application demands of the end user with minimal time spent designing new hardware. Additionally, the use of MPSoCs allows designers to generate new devices very quickly and thus reducing the time to market. In this work, a complete MPSoC synthesis design flow is presented. We first present a technique \cite{leary1_intro} to address the synthesis of the interconnect architecture (particularly Network-on-Chip (NoC)). We then address the synthesis of the memory architecture of a MPSoC sub-system \cite{leary2_intro}. Lastly, we present a co-synthesis technique to generate the functional and memory architectures simultaneously. The validity and quality of each synthesis technique is demonstrated through extensive experimentation.

Description
Individual behavior change is a goal of many public policies directed at people of low socioeconomic status. Without evidence of behavioral change, these policies cannot be considered a success: a process of co-production where some level of cooperation between the client and program administrators is required to successfully meet program objectives. The Special Supplemental Nutrition Program for Women, Infants and Children (WIC), is one example of a co-production design. WIC encourages women to engage in healthy behaviors by providing healthy food along with nutrition education to improve the health status of low-income families. However, while WIC is one of the most studied nutrition programs, little attention has been paid to the nutrition education portion or to interactions between staff members and participants. This research draws on the public policy and administration literature about street-level bureaucrats and co-production, which provides a framework for understanding the purposeful, inter-dependent relationships between front-line service providers and clients. However, neither literature explicates the process of interactions that is expected to lead to client behavior change and co-production. The primary contribution of this research is the creation of a grounded theory that identifies and explains the WIC interaction process as one of "negotiating healthy self-government". Based on analysis of three months of observations of WIC encounters in two clinics, this research finds that participants and staff members enter into tacit and explicit negotiations concerning the degree to which participants should govern their family's nutrition-related behavior. Clients actively shape the interactions by demonstrating their discipline and efforts to feed their families, while staff members refine and reinforce self-governing behaviors through assessing action, and providing advice to ensure behaviors meet recommendations. Finally, participants and staff members distinctly link self-governing behavior to identity: "good mothers" feed their children healthy food and govern their behaviors to meet nutritional recommendations. This research has implications for the study of behavior change promotion in public programs by introducing the concept of identity as a mechanism for governance and explicating the interaction process between front-line service providers and clients

Description
This study uses the ontological lenses of discourse theory to conduct a critical mixed-methods analysis of state statutes related to prostitution and sex trafficking. The primary research question of the study was, "How do state laws communicate and reinforce discourses related to sex trafficking and prostitution and how do these discourses reinforce hegemony and define the role of the state?" A mixed methods approach was used to analyze prostitution and sex trafficking related annotated and Shepardized statutes from all fifty states. The analysis found that not all prostitution related discourses found in the literature were present in state statutes. Instead, statutes could be organized around five different themes: child abuse, exploitation, criminalization, place, and licensing and regulation. A deeper analysis of discourses present across and within each of these themes illustrated an inconsistent understanding of prostitution as a social problem and an inconsistent understanding of the legitimate role of the state in regulating or criminalizing prostitution. The inconsistencies in the law suggest concerns for equal protection under the law based upon a person's perceived deservingness, which often hinges on his or her race, class, gender identity, sexuality, age, ability, and nationality. Implications for the field include insights into a substantive policy area rarely studied by policy and administration scholars, a unique approach to mixed methods research, and the use of a new technique for analyzing vast quantities of unstructured data.

Description
This dissertation explores the megamachine, a prominent metaphor in American humanist and philosopher of technology, Lewis Mumford's Myth of the Machine series. The term refers critically to dynamic, regimented human capacities that drive scientific and technical innovation in society. Mumford's view of the nature of collectives focuses on qualities and patterns that emerge from the behavior of groups, societies, systems, and ecologies. It is my aim to reenergize key concepts about collective capacities drawn from Lewis Mumford's critique of historical and modern sociotechnical arrangements. I investigate the possibility of accessing those capacities through improved design for Technology Assessment (TA), formal practices that engage experts and lay citizens in the evaluation of complex scientific and technical issues.
I analyze the components of Mumford's megamachine and align key concerns in two pivotal works that characterize the impact of collective capacities on society: Bruno Latour's Pasteurization of France (1988) and Elias Canetti's Crowds and Power (1962). As I create a model of collective capacities in the sociotechnical according to the parameters of Mumford's megamachine, I rehabilitate two established ideas about the behavior of crowds and about the undue influence of technological systems on human behavior. I depart from Mumford's tactics and those of Canetti and Latour and propose a novel focus for STS on "sociotechnical crowds" as a meaningful unit of social measure. I make clear that Mumford's critique of the sociotechnical status quo still informs the conditions for innovation today.
Using mixed mode qualitative methods in two types of empirical field studies, I then investigate how a focus on the characteristics and components of collective human capacities in sociotechnical systems can affect the design and performance of TA. I propose a new model of TA, Emergent Technology Assessment (ETA), which includes greater public participation and recognizes the interrelationship among experience, affect and the material in mediating the innovation process. The resulting model -- the "soft" megamachine --introduces new strategies to build capacity for responsible innovation in society.

Description
The quality and quantity of talented members of the US STEM workforce has
been a subject of great interest to policy and decision makers for the past 40 years.
Recent research indicates that while there exist specific shortages in specific disciplines
and areas of expertise in the private sector and the federal government, there is no
noticeable shortage in any STEM academic discipline, but rather a surplus of PhDs
vying for increasingly scarce tenure track positions. Despite the seeming availability
of industry and private sector jobs, recent PhDs still struggle to find employment in
those areas. I argue that the decades old narrative suggesting a shortage of STEM
PhDs in the US poses a threat to the value of the natural science PhD, and that
this narrative contributes significantly to why so many PhDs struggle to find career
employment in their fields. This study aims to address the following question: what is
the value of a STEM PhD outside academia? I begin with a critical review of existing
literature, and then analyze programmatic documents for STEM PhD programs at
ASU, interviews with industry employers, and an examination the public face of value
for these degrees. I then uncover the nature of the value alignment, value disconnect,
and value erosion in the ecosystem which produces and then employs STEM PhDs,
concluding with specific areas which merit special consideration in an effort to increase
the value of these degrees for all stakeholders involved.

Description
This thesis examines Care Not Cash, a welfare reform measure that replaced traditional cash General Assistance program payments for homeless persons in San Francisco with in-kind social services. Unlike most welfare reform measures, proponents framed Care Not Cash as a progressive policy, aimed at expanding social services and government care for this vulnerable population. Drawing on primary and secondary documents, as well as interviews with homelessness policy experts, this thesis examines the historical and political success of Care Not Cash, and explores the potential need for implementation of a similar program in Phoenix, Arizona.

Description
In the fifteen years between the discovery of fetal alcohol syndrome (FAS) in 1973 and the passage of alcohol beverage warning labels in 1988, FAS transformed from a medical diagnosis between practitioner and pregnant women to a broader societal risk imbued with political and cultural meaning. I examine how scientific, social, moral, and political narratives dynamically interacted to construct the risk of drinking during pregnancy and the public health response of health warning labels on alcohol. To situate such phenomena I first observe the closest regulatory precedents, the public health responses to thalidomide and cigarettes, which established a federal response to fetal risk. I then examine the history of how the US defined and responded to the social problem of alcoholism, paying particular attention to the role of women in that process. Those chapters inform my discussion of how the US reengaged with alcohol control at the federal level in the last quarter of the twentieth century. In the 1970s, FAS allowed federal agencies to carve out disciplinary authority, but robust public health measures were tempered by uncertainty surrounding issues of bureaucratic authority over labeling, and the mechanism and extent of alcohol’s impact on development. A socially conservative presidency, dramatic budgetary cuts, and increased industry funding reshaped the public health approach to alcoholism in the 1980s. The passage of labeling in 1988 required several conditions: a groundswell of other labeling initiatives that normalized the practice; the classification of other high profile, socially unacceptable alcohol-related behaviors such as drunk driving and youth drinking; and the creation of a dual public health population that faced increased medical, social, and political scrutiny, the pregnant woman and her developing fetus.

Description
Cities today face new economic, political, and social challenges spurred, in part, by the growth of immigrant and newcomer populations and increasing competitive pressure in the context of contemporary globalization. In the face of these challenges, some U.S. city and county governments have adopted the “welcoming city initiative,” which promotes both immigrant integration and economic growth. To date, little research has explored why different U.S. cities decide to pursue the welcoming city initiatives, what cities really hope to achieve through them, or what governing arrangements emerge to develop and implement these initiatives. In addition to illuminating the emerging discursive, political, and organizational dynamics of welcoming, this dissertation contributes to the literatures in urban asset development, urban regime theory, and political and bureaucratic incorporation.
Drawing on 30 interviews with key actors and document analysis, this dissertation employs a multiple case study design to conduct an interpretive policy analysis of the initiatives of four U.S. welcoming cities: Austin, Texas; Boise, Idaho; Chicago, Illinois; and Philadelphia, Pennsylvania. The analysis explores three independent but interconnected themes. The first theme concerns multiple, context-specific framings of “welcoming” and the types of assets cities seek to leverage and develop through the welcoming city initiatives. This investigation finds that while each city puts a priority on developing a certain set of assets based on its unique political, economic, and demographic contexts, welcoming efforts tend to encourage immigrant entrepreneurialism, the leveraging newcomers’ human capital and financial assets, and the development place-based assets to attract and retain newcomers. The efforts to strengthen community capacity seek to institutionalize a new norm of welcoming, structure immigrant-friendly governance practices, and engage newcomers and longer-term residents in their community affairs. The second theme probes the ways in which these four cities create and maintain governing regimes for the initiative. The analysis finds that, while the four cities develop different governing structures, all pursue the creation of mixed types of governing coalitions that combine pro-growth and opportunity expansion regimes by incorporating the goals of economic growth and immigrant integration. The third theme investigates different modes of immigrant incorporation and their contribution to immigrant integration, the final stage in immigrant settlement. The analysis suggests that political leaders and bureaucratic agencies of the welcoming cities tend to build reciprocal relationships, rather than principal-agent relationships, in which political leaders rely on the positional, professional, and technical expertise of bureaucrats. In these early stages on the initiative, political and bureaucratic incorporation aim to create institutional changes that help immigrants and newcomers to be viewed as political constituents and clients of bureaucratic agencies.
This dissertation broadly concludes that the welcoming city initiative is a promising new urban economic development framework that could reshape urban space by integrating pro-growth demands with social integration and inclusion. Going forward, however, deeper consideration of the perspectives and rights of immigrants and newcomers themselves is needed in these initiatives.

Description
With more than one third of Americans considered to be obese, obesity is a public health issue in the United States. While obesity is linked to and caused by a number of factors, sugar sweetened beverage (SSB) consumption is a major contributor to increased obesity rates. For the purposes of this paper, SSBs will include any beverage in which sugar is added. This includes juices that are not 100% fruit juice, coffee or tea drinks that are sugar sweetened, energy or sport drinks, and most commonly, soda. Excess sugar in the diet is substantially linked to obesity and negative health effects. SSBs represent the primary source of added sugar in the average American diet. Part I of this paper will discuss obesity as a public health problem and establish the link between consumption of SSBs and poor health effects. Part II will discuss the public policy instrument families and the strengths and weaknesses of each policy approach. Part III will identify current policies specifically focused on curbing SSB consumption. Each policy will be analyzed for efficacy based on available scientific research. Lastly, Part IV will propose new policy alternatives and ways to improve current policies. A final policy recommendation will be presented as an ideal roadmap for policy makers looking to address the link between SSB consumption and obesity.

Description
This dissertation examines the efforts of the Carnegie Image Tube Committee (CITC), a group created by Vannevar Bush and composed of astronomers and physicists, who sought to develop a photoelectric imaging device, generally called an image tube, to aid astronomical observations. The Carnegie Institution of Washington’s Department of Terrestrial Magnetism coordinated the CITC, but the committee included members from observatories and laboratories across the United States. The CITC, which operated from 1954 to 1976, sought to replace direct photography as the primary means of astronomical imaging.
Physicists, who gained training in electronics during World War II, led the early push for the development of image tubes in astronomy. Vannevar Bush’s concern for scientific prestige led him to form a committee to investigate image tube technology, and postwar federal funding for the sciences helped the CITC sustain development efforts for a decade. During those development years, the CITC acted as a mediator between the astronomical community and the image tube producers but failed to engage astronomers concerning various development paths, resulting in a user group without real buy-in on the final product.
After a decade of development efforts, the CITC designed an image tube, which Radio Corporation of American manufactured, and, with additional funding from the National Science Foundation, the committee distributed to observatories around the world. While excited about the potential of electronic imaging, few astronomers used the Carnegie-developed device regularly. Although the CITC’s efforts did not result in an overwhelming adoption of image tubes by the astronomical community, examining the design, funding, production, and marketing of the Carnegie image tube shows the many and varied processes through which astronomers have acquired new tools. Astronomers’ use of the Carnegie image tube to acquire useful scientific data illustrates factors that contribute to astronomers’ adoption or non-adoption of those new tools.
