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 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.

Affirmative action is an education policy adopted by higher education institutions in the 1960s, where an applicant’s race is taken into account to some degree when being evaluated for admission to a college or university. The practice of affirmative action, or race conscious-admissions, has been repeatedly challenged in the legal system and remains a controversial and polarizing topic amongst the general public, campus leaders, and policy makers. Despite a vast amount of research on the effects of affirmative action policies on student and institutional behaviors and outcomes, such as college applications and enrollments, considerably less research has examined students’ attitudes towards race-conscious admissions policies. Even less research has focused on students in academic disciplines, especially STEM or engineering. Likewise, there is a paucity of research that explores students’ perceptions and knowledge of how affirmative action is implemented in practice. To address these gaps, this study investigates undergraduate engineering students’ knowledge of and attitudes towards affirmative action admissions policies in higher education. The Student Attitudes Towards Admissions Policies Survey (SATAPS) was designed to assess students’ knowledge of and attitudes regarding affirmative action practices in higher education admissions. This survey was administered to undergraduate engineering students and a comparison group of education students at 42 colleges/universities in the United States. Data were analyzed utilizing confirmatory factor analysis and hierarchical regression. Results demonstrated that students have low levels of knowledge about affirmative action, and have misconceptions about how the policy functions in practice. There was no difference in engineering and education students’ level of support for affirmative action; however, underrepresented minority students in engineering were more supportive of affirmative action. Results also indicated that students’ beliefs and values were the strongest predictors of attitude towards affirmative action, so much so that this negated the significance of demographic and personal characteristics, which was observed in the majority of previous studies. Results highlight a complicated relationship between demographic characteristics, personal variables, knowledge, institutional context, beliefs/values, and attitude towards affirmative action admissions policies in higher education.

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.

The United States accounts for only 4% of the world’s female population, but it is home to more than 30% of the world’s incarcerated women, the majority of whom will eventually attempt a successful reentry into society. Almost half of the incarcerated women in the United States have not obtained a high school diploma or equivalency, and only 31% have attempted some college, compared to 58% among the general public (Ewert & Wildhagen, 2011). There is ample evidence of the impact of a post-secondary degree on reducing recidivism and increasing reentry success. However, the Arizona Department of Corrections reports that of the more than 40,000 people incarcerated in November of 2019, only 5,333, or 12.5%, were involved in any type of educational programming while incarcerated (2019).

Few studies have looked closely at the barriers to higher education for formerly incarcerated individuals, and even fewer have focused on women. The purpose of this qualitative action research study was to examine the educational experiences of formerly incarcerated women through the lenses of critical social theory (Freeman & Vasconcelos, 2010; Freire, 1970) and possible selves theory (Markus & Nurius, 1986) in an effort to more fully understand low educational attainment in this population and use this knowledge to develop an effective, participant-informed intervention and provide recommendations for university outreach programs. Study participants were formerly incarcerated women and individuals who work with this population. Data were collected from in-depth semi-structured interviews and materials created during the College After Prison Workshop which was developed for this project.

Interviews revealed that the women in this study crave a sense of belonging, feel regret over their lost possible selves, experience a fear of standing still or going backward, and have a strong desire to help others. Findings suggest that colleges and universities can support formerly incarcerated women in the post-secondary system by curating a community of scholars and demonstrating a clear path forward for formerly incarcerated women by reducing systemic barriers.

The problem of practice addressed in this mixed-methods research study is assessing whether participating in professional development workshops helped community college instructors improve their pedagogical practices, leading to improved student success and achievement rates. In this study, I explore the effects of an intervention I designed to help English 101 instructors teach a new, direct-placement composition class, which was created to comply with the mandates of AB-705, an educational reform bill in California. I used three guiding theories to undergird and evaluate the intervention: Darling-Hammond et al.'s Accountability Approach (2014), Freire's Critical Pedagogy (1970), and Kirkpatrick and Kayser-Kirkpatrick’s Model of Training Effectiveness (2009). To address the research questions of this study, I analyzed pre- and post-surveys, faculty interviews, and student success and retention data. The results from the data were mixed. While the quantitative survey data did not support the claim that the College of the Canyons (COC) SkillShare Workshops affected instructors’ attitudes about teaching and their teaching behaviors, the qualitative interview data showed that the workshops did improve instructors’ professional capacities and were a valuable professional development resource. Additionally, the quantitative institutional data demonstrated that workshop participation significantly increased instructors’ student success and retention rates.

Presidents exercise influence over policy discussion and options in America by the frequency and language they use to describe the current conditions, the perceived problems, and the solutions. The ability for presidents to articulate problems and solutions assumes an underlying purpose exists. This study examines how presidents frame the policy discussion for education in America and how they describe the purpose of education in the public record: the benefit of education is for society (common good), or the benefit it to the student (private good). Then the study examines the extent to which those frames stay consistent or are variable within and between administrations. The study utilizes presidential issue framing and agenda-setting to examine historical documents in the Public Papers of the President archive to determine the articulated purpose using the framework proposed by David Labaree. This study focuses on three administrations of the most recent period of federalism in education policy in America, starting with Bill Clinton and ending with Barack Obama. The study found that President William Clinton used the purposes of Social Mobility and Social Efficiency most frequently, President George W. Bush used Social Efficiency – Public Good and Social Efficiency – Private Good most, and President Barack Obama used Social Efficiency – Public Good more than all other frames. All three presidents maintained relatively consistent use of their prominent frames throughout their administrations with some indication that slight shifts may occur. All three presidents had low utilization of the frame Democratic Equality, and all used the combined frame Social Efficiency the most. Some variation between the utilization of the second-level codes of Private Good and Public Good do exist between administrations. The prominence of the combined frame Social Efficiency across administrations may suggest a more crystalized definition for the purpose of K-12 education in America.
