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
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
The Luminosity Lab, located at Arizona State University, is a prototype for a novel model of interdisciplinary, student-led innovation. The model’s design was informed by the following desired outcomes: i) the model would be well-suited for the 21st century, ii) it would attract, motivate, and retain the university’s strongest student talent, iii) it would operate without the oversight of faculty, and iv) it would work towards the conceptualization, design, development, and deployment of solutions that would positively impact society. This model of interdisciplinary research was tested at Arizona State University across four academic years with participation of over 200 students, who represented more than 20 academic disciplines. The results have shown successful integration of interdisciplinary expertise to identify unmet needs, design innovative concepts, and develop research-informed solutions. This dissertation analyzes Luminosity’s model to determine the following: i) Can a collegiate, student-driven interdisciplinary model of innovation designed for the 21st century perform without faculty management? ii) What are the motivators and culture that enable student success within this model? and iii) How does Luminosity differ from traditional research opportunities and learning experiences?
Through a qualitative, grounded theory analysis, this dissertation examines the phenomena of the students engaging in Luminosity’s model, who have demonstrated their ability to serve as the principal investigators and innovators in conducting substantial discovery, research, and innovation work through full project life cycles. This study supports a theory that highly talented students often feel limited by the pace and scope of their college educations, and yearn for experiences that motivate them with agency, achievement, mastery, affinity for colleagues, and a desire to impact society. Through the cumulative effect of these motivators and an organizational design that facilitates a bottom-up approach to student-driven innovation, Luminosity has established itself as a novel model of research and development in the collegiate space.

Description
This action research project was a concurrent mixed method case study design The purpose of this action research study was to begin to understand how an institution of higher education can best support creativity and innovation of university staff members. More specifically this study looked at the influence of a design thinking workshop on university staff perceived creative and innovative ability. Additionally, this study looked at the influence of individual attributes on staff creativity, and the influence of organizational attributes on staff innovation. Amabile and Pratt’s Dynamic Component Model of Creativity and Innovation in Organizations informed this study. Participants for this study were recruited from the Educational Outreach and Student Services division of Arizona State University at the Downtown Phoenix campus. Qualitative and quantitative data were collected using a Creativity and Innovation Survey (CIS) and individual interviews. The Creativity and Innovation Survey was distributed to staff before and after they participated in a two module design thinking workshop. Interviews with staff occurred after the conclusion of the workshops. In responses to the CIS and in interview staff had a strong belief in their ability to be creative and innovative in the workplace. A correlational analysis of CIS data indicated that a positive and significant relationship existed between creativity and individual attributes, as well as between, innovation and organizational attributes. Staff also expressed these relationships during interviews. The themes of collaboration, supervision, and resources each emerged from the interview data as important influencers of staff creativity and innovation. Although staff expressed there was a value in the design thinking workshops during interviews, a significant difference was not found in staffs’ perceived creativity and innovation after participating in the design thinking workshop. Implications for practice and for future research are discussed.

Description
Development is a compelling, but imprecise goal. Although the concept can motivate action and mobilize resources, fundamental questions about what it means to ‘develop’ and what actions are required to achieve that goal remain the subject of intense debate. Faced with this uncertainty, development actors can look to two sources of guidance: other disciplines, or the practice of development itself. This dissertation explores the origins of the theories which guide development action and argues that in order for development to deliver on its mandate it must reject supposedly universal theories borrowed from other disciplines (‘exogenous’ theories) and instead must develop contingent, local theories based in the on-the-ground experiences of those doing development (‘endogenous’ theories).
This argument is demonstrated using the case of innovation theory in Guyana. Innovation and development are both popular ways to make sense of change and in recent decades they have become conflated, with innovation being presented as a near-universal fix for development problems. This discourse has taken root in Guyana, where the recent discovery of oil has made the questions of development increasingly urgent and the promise of innovation increasingly attractive. The argument proceeds in four phases:
Chapter one explores how and why certain theories become influential in development, then discusses the implications of doing development work based on ‘exogenous’ versus ‘endogenous’ theory. It then proposes four guidelines for the use of theory in development.
Chapter two traces how innovation came to become understood as a solution to development problems, and assesses whether and under what conditions it can be expected to contribute to development.
Chapter three turns to Guyana, and builds on interviews and participant observation to present an endogenous theory of innovation in Guyana. The chapter also explores the practical and methodological challenges of building such a theory.
Chapter four compares the endogenous theory of innovation presented in the previous chapter to several dominant exogenous theories, exploring the policy implications of each and demonstrating why the endogenous theory provides a superior source of guidance for development action in Guyana.
