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.

The dissertation focuses on one Truku (Indigenous) village in eastern Taiwan and aims to understand the processes and possibilities of bottom-up language revitalization. In 2012, the National Geographic Genographic Legacy Fund supported the village to start a community-driven language revitalization initiative. Drawing on scholarship guided by critical Indigenous research methodologies, critical sociocultural approaches to language policy and planning, and sociocultural approaches to learning, this study is an attempt to generate qualitative ethnographic research to facilitate local praxis. The major findings are four: Firstly, after decades of colonialism, villagers' lived experiences and language ideological standpoints vary significantly across generations and households, which constraints the possibility of collective endeavors. Secondly, building on previous scholars' emphasis on "ideological clarification" prior to language revitalization, I identify the dimension of embodied ideological differences, using cultural historical activity theory to illustrate how certain "mainstream" artifacts (e.g. orthography) can confine orally dominant elders' capacity to contribute. In a similar vein, by closely examining children's voices and language performances, I highlight children's theory of language as relationship-building and a theory of learning as participation in communities of participation, which stand in stark contrast to adult educators' constructs of acquisition and proficiency in traditional SLA. Finally, inspired by children and elders' voices, methodologically I argue for a relational conceptualization of agency and propose a relationship-oriented language revitalization framework. Such framework values and incorporates existing social relationships in praxis, and requires researchers and practitioners to humbly recognize the work of power in social relations and develop a trusting, reflective bond with the villagers before rushing to impose agendas. This dissertation contributes to the scholarship of language policy and planning by incorporating sociocultural learning theories designed to generate praxis-oriented analysis. By contextualizing identity and SLA processes in an Indigenous context, the study also illuminates the affective dimension of language learning and education. Overall this study offers valuable insights for scholars, educators, and practitioners interested in community-based language education. Equally important, this research represents the voices of multiple generations of Truku people, deeply committed to ensuring that future generations remain connected to their heritage language, knowledge system, and ways of being.

This study examines the contemporary school placement decisions of Navajo parents in the reservation community of Piñon, Arizona. School placement decisions are defined as the school where the parent chooses to enroll his/her child for schooling. Twelve Navajo parents participated in this qualitative study, which explored their past educational experiences in order to garner insight into the current school placement choices they have made for their children. Navajo parents who live within the community of Piñon, AZ who currently have school-aged children living in their household were recruited to participate in this study. Participants took part in 60- to 90-minute interviews that included questions related to their prior educational experiences and current school placement choices for their children. Parents were given an opportunity to reflect about the school placement decisions they have made for their children. The variety of schools Navajo parents are able to choose from were illuminated. These findings have implications for education decision makers by providing insight into which schools parents are choosing and why. The study will assist Navajo Nation policy makers in future educational planning, and may have more general implications for American Indian/Alaskan Native education. This may assist Navajo Education policy makers in making future decisions regarding the newly developed Navajo Department of Education and its education planning. Participants will also benefit from the study by being able to understand how the past has impacted the school placement choices they have made. In doing so parents may be better able to articulate the impetus behind the choices they make for their children, thereby becoming better advocates for themselves and their children. The results of this study impacts scholarly literature as a new viewpoint in the area of school choice. Navajo parents represent a distinct group who make educational choices within a specific context. This study is unique as the impact of historical Indian education policies is considered. Future studies can further expand on the topic creating a unique area of research in the field of Indian education.

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.

This qualitative study investigates the experiences of ten focal youth who came to the United States as refugees and were placed in Structured English Immersion (SEI) programs in Arizona high schools. The educational language policy for Arizona’s public schools (during the 2014-2015 school year) mandates SEI include four 60-minute classroom periods devoted to reading, writing, grammar, oral English exclusively. Students in SEI thus have restricted access to the full-range of general education courses required for graduation, as well as limited opportunities for social interaction with peers enrolled in the “mainstream” curriculum.

The study investigates how youth understand and navigate the school language policy, practices and discourses that position them, and specifically seeks to learn how being identified as an “English Language Learner” interacts with youth’s construction of academic and social identities. Adopting a critical sociocultural theory of language policy (following McCarty, 2011), employing ethnographically-informed research methods, and using social-positioning as an analytic lens, I aim to learn from an emic youth perspective and to amplify their voices. Eight Somali and two Iraqi students took part in two individual in-depth interviews; five students participated in a focus group; and all engaged in numerous informal conversations during 22 researcher site visits to an ethnic community-based organization (ECBO) and a family apartment.

Narratives recounting the participants’ lived experiences in the socio-cultural context of high school provide powerful examples of youth asserting personal agency and engaging in small acts of resistance to contest disagreeable positioning. The findings thus support the conceptualization of youth as creative producers of hybridity in response to their environments. This work also confirms the perennial significance of social categories and “othering” in high school. Though the institutional structure of separate classrooms and concomitant limited access to required courses hinder the study participants’ academic progress, the youth speak positively about the comfort of comradery and friendship in the shared safe space of the separate SEI classroom. The dissertation concludes with participants’ recommendations for educators, and the people refugee youth interact with in the context of high school, to improve refugee youth’s experience.

According to my 2016 survey of ASU undergraduate students, 33% have used stimulant medications (e.g. Adderall or Ritalin) without a prescription to study. I view this practice as a step towards cognitive enhancement, which is the deliberate application of biotechnology to radically alter the human condition. From a foresight perspective, the ability to actively improve human beings, to take our evolutionary destiny into our own hands, may be a turning point on par with agriculture or the use of fossil fuels. The existential risks, however, may be greater than the benefits—and many of the most radical technologies have made little documented progress.

I turn to an actual example where people are trying to make themselves marginally better at academic tasks, as a guide to how future transformative development in human enhancement may be incorporated into everyday practice. This project examines the history and context that led to the widespread use of stimulant medication on college campuses. I describe how Attention Deficit Hyperactivity Disorder (ADHD), for which stimulant medication is prescribed and diverted, governs students, negotiates relationships between parents and school authorities, and manages anxieties resulting from a competitive neoliberal educational system. I extend this archeology of ADHD through the actions and ethical beliefs of college students, and the bioethical arguments for and against human enhancement. Through this work, I open a new space for an expanded role for universities as institutions capable of creating experimental communities supporting ethical cognitive enhancement.

This is a qualitative case study using ethnographic methods of how one school community has been able to negotiate Arizona's restrictive English only language policies. Drawing from classroom and school-wide observations, extensive interviews, and document collection, this case study explores three key questions in relation to this school's negotiation process: 1) What characterizes the curriculum for English learners (ELs) and bilingual students at the case study school? 2) How do key actors, processes, and cultural practices at the case study school support the negotiation of Proposition 203 and House Bill 2064? and 3) What are the perspectives of key school community stakeholders in relation to the curriculum supporting bilingualism and the policy negotiation process? Findings show that by sharing certain key beliefs and practices, the school community has been able to work together, at times through struggle and perseverance, to negotiate for what they believe to be most important in school. They do so by sharing such key beliefs as the importance of seeing the whole child and teaching in ways that are real and meaningful. They also negotiate by engaging in a set of shared practices, which include: the use of Spanish campus-wide both for instruction and for the life and operation of the school, the cultivation of relationships amongst all school community members, and key curricular practices. These practices include providing a variety of learning experiences, especially those based upon the Arts, as well as a curriculum that focuses on providing opportunities to examine real world issues in an integrated and in-depth manner, to learn by integrating students' language, families, and experiences into the curriculum, and has a final goal of creating students who are critical thinkers, self-advocates, and agents within their own lives. All of these beliefs and practices contribute to a strong sense of community. It is this sense of community and the shared beliefs and practices, along with the increased agency this interconnectedness creates for all stakeholders, which has facilitated the successful use of parent waivers. These parent waivers have enabled parents to continue choosing alternative language education programs to those mandated by the state, namely integrated content and English instruction within the mainstream K-4 classroom and the Spanish/English dual language program option at the 5-8 grade levels.
