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
Visualizations are an integral component for communicating and evaluating modern networks. As data becomes more complex, info-graphics require a balance between visual noise and effective storytelling that is often restricted by layouts unsuitable for scalability. The challenge then rests upon researchers to effectively structure their information in a way that allows for flexible, transparent illustration. We propose network graphing as an operative alternative for demonstrating community behavior over traditional charts which are unable to look past numeric data. In this paper, we explore methods for manipulating, processing, cleaning, and aggregating data in Python; a programming language tailored for handling structured data, which can then be formatted for analysis and modeling of social network tendencies in Gephi. We implement this data by applying an algorithm known as the Fruchterman-Reingold force-directed layout to datasets of Arizona State University’s research and collaboration network. The result is a visualization that analyzes the university’s infrastructure by providing insight about community behaviors between colleges. Furthermore, we highlight how the flexibility of this visualization provides a foundation for specific use cases by demonstrating centrality measures to find important liaisons that connect distant communities.

Description
This study, using personal experience as a basis for curiosity, seeks to explore why some portion of engineering students change their majors, whom I am calling "switchers." Another set of students are "persisters," or students who are still currently enrolled in engineering but have considered other paths. In collecting data, two students from each set, within the author's social network, were interviewed. Articles primarily concerning attrition and retention within engineering education were surveyed in this study. The literature's reasons for leaving engineering were tabulated and used to code these interviews, then the trends outside of this table were studied. The literature and all interviewees both stated that engineering students struggle with poor teachers, poor teaching methods, poor curriculum, and a lack of time. Outside of the literature, job prospects caused the interviewed students to feel trapped in engineering. Whether to take this study beyond the exploratory stage, and how to do that, is being considered currently.

Description
This paper introduces MisophoniAPP, a new website for managing misophonia. It will briefly discuss the nature of this chronic syndrome, which is the experience of reacting strongly to certain everyday sounds, or “triggers”. Various forms of Cognitive Behavioral Therapy and the Neural Repatterning Technique are currently used to treat misophonia, but they are not guaranteed to work for every patient. Few apps exist to help patients with their therapy, so this paper describes the design and creation of a new website that combines exposure therapy,
relaxation, and gamification to help patients alleviate their misophonic reflexes.

Description
This thesis first examines the history and contemporary landscape of school mental health, offering evidence for schools as an essential component of the child and adolescent system of care. It then provides contemporary discussion around the importance of design in public administration, as well as analyzes the current design model of school-based mental health services, including key actors, normative assumptions, and underlying conceptual models to demonstrate the outdated presumptions that have led to a model that is not designed to adapt to the unique needs of students, especially after the COVID-19 pandemic. Building on contemporary theory of design in public administration, I argue that the largely fragmented, decentralized, bureaucratic, complex, and underdeveloped design of school-based mental health services mainly developed in the 1970s and 1980s has reached its limits and cannot adapt to new societal variables. Lastly, I discuss said limitations of this model to argue for a conceptual and practical re-design of the current system of school-based mental health systems in the United States.

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.

With a fresh democratic energy emerging from newer generations, there is an increasing
number of youth becoming politically active and civically engaged. Many of whom are active
and engaged are college students, seeking change not only within politics and society, but within
their institution. At Arizona State University (ASU), the institution is spread across four unique
campuses in which each of the campuses holds its own undergraduate student government.
Within the Associated Students of Arizona State University (ASASU), each Undergraduate
Student Government (USG) experiences low voter turnout every year in their elections and high
turnover rates. Understanding why students chose to be involved in the first place is a major
question.

Description
Education is one of the most important factors in a person’s life - it shapes your friends as a child, your future career, and has tangible effects on a person’s earning potential, health, and more. The state government has the responsibility, and privilege, to provide every child with a K-12 education through a system of public schools as directed by the Arizona Constitution. The Arizona State Legislature expanded the public school system to include charter schools to facilitate more choices for students and parents in the delivery of education. In the late 1990s and throughout the last two decades, Arizona would form, fund, and begin to prioritize a parallel publicly-funded private education system.
Through the creation of the School Tuition Organization income tax credits, vouchers, and the Empowerment Scholarship Account program the Arizona State Legislature has systematically diverted funds from public schools to private education institutions. A report by the Center for the Future of Arizona, The Arizona We Want: The Decade Ahead, identified a range of issues, including education, that a majority of Arizonans find consensus on. Arizonans agree that a quality K-12 public education system is one of the most important issues to improving Arizona’s future and 73% agree that more money should be spent on K-12 education. Arizona leaders have shown a concerning willingness to ignore expressed public values in relation to education - these policy decisions have left our state public schools, which 88% of Arizona children attend, critically underfunded. Now is the time for all Arizonans to support the future we want by pushing for a strong, well-funded K-12 public education system.
