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
ABSTRACT This study examined the schooling experiences and perceptions of resettled sub-Saharan African middle school refugee students in a metropolitan area of the United States Southwest. The research questions underpinning this study included: What are the schooling experiences and perceptions of resettled sub-Saharan African middle school refugee students in a southwestern U.S. state? 1a) How do they view their relationships with their teachers and peers? 1b) Can they identify a teacher or school staff member in their school community who is a significant resource for them? and 1c) What factors contribute to their challenges and successes in their school community? This qualitative study documented and analyzed the schooling experiences and perceptions of resettled refugee middle school students, who are relatively new to the U.S. educational system. Purposive and convenience sampling were sources utilized in selecting participants for this study. Semi-structured interviews and focus groups were used to capture the stories of 10 resettled sub-Saharan African refugee students enrolled in 7th and 8th grade, who have lived in the U.S. not more than 10 years and not less than three years. Among the participants, half were male and half female. They came from six countries: Burundi, Democratic Republic of Congo, Liberia, Rwanda, Sierra Leone and Somalia. Findings of the study revealed six major themes: teachers' helpfulness, positive perceptions of school, friends as resources at school, disruptive students in the classroom, need for better teachers, and before and after school activities. Overall, the participants in the study expressed a positive perception of their teachers and their schools, yet presented a dichotomous view of their schooling experiences and perceptions.

Description
Given the surge of immigrant and resettled refugee student enrollment in public schools, a strong understanding of the transition process for these students and their families and facilitating the creation of effective schooling contexts are major educational priorities. It is critical to determine how to best support and assist resettled refugee students in academic and other endeavors. This study seeks to better understand the perspectives of resettled refugee students who are recent high school graduates and their mentors in order to contribute practical insights into resettled refugee education and to give voice to these students. Informed by sociocultural theories as reflected in the works of Daniels, Cole and Wertsch, (2007) and others, twelve resettled refugees from Bhutan, Iraq and Burma (aka Myanmar) and ten mentors participated in individual interview sessions and focus group discussions. The study took place in Arizona. The participants' responses were audio-recorded, transcribed, interpreted, coded, and categorized into themes. Study findings suggested that: resettled refugee students struggled with adjusting to their new school system. They were marginalized and faced discrimination and suffered low teacher expectations. They were placed in English language classes that they felt were not beneficial to them; and almost all attended inner city urban schools in areas with a high poverty concentration characterized by gang and drug activities that further adversely affected their performances. Against the odds, with the help of their mentors, striving for a better life, commitment to family, and resilience, the study participants were able to not only complete their high school education on time but earned impressive grade point averages of between 3.5 to 4.2 that helped five of them win scholarships to four-year colleges.

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
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.

Description
According to UNESCO's 2010 survey results of 58 member countries, 34 of the countries had less than 1 percent of children enrolled in special education programs. Ten of these countries provided special education provision for less than .01 percent of children. However, the demand to educate students with disabilities in inclusive educational settings continues to grow. Thus, there are many national initiatives aimed at finding ways of creating forms of inclusive educational settings that can respond to children with special needs. In this study, the purpose was to better understand the processes of local adaptation and modification of UNESCO's inclusive education policies, the possible resistances to global forces in inclusive education in Turkey, and the consequences of the implications of those policies in Ankara, Turkey from local educators' views. With that goal in mind, recently adopted Turkish inclusive educational policies implemented after the Salamanca Statement in 1994 were reviewed on a selective basis. The discussion of the policy and document analysis section helped to make connections between the global inclusive education policy changes and local practices in the Turkish education system. In the second part of the study, semi-structured interviews were conducted with local educators in Ankara (teachers, administrators, and academic advisors) and policy makers from the Ministry of National Education. An analysis of the interview data highlighted the various complexities, tensions, and inadequacies in the conceptualization of inclusive education in Turkish public primary schools that study participants have observed and experienced. In light of the findings, possible reasons behind the gap between theory and practice and the discrepancies between Western and Turkish interpretations of inclusive education in Turkey are discussed. In the current inclusive education system in Turkey, the challenge of modifying deeply held attitudes at both personal and institutional levels, providing clearly constructed inclusive education policies and approaches, offering appropriate training to key stakeholders, and making adequate resources available appear to be the primary issues for moving forward with full inclusion initiatives.

ABSTRACT
This study examines the language and literacy experiences of Kurdish minority children during their first year of mainstream schooling in a southeastern village in Turkey. I employed ethnographic research methods (participant observation, multi-modal data collection, interviewing, and focus groups) to investigate the language practices of the children in relation to language ideologies circulating in the wider context. I focused on the perspectives and practices of one 1st grade classroom (14 students) but also talked with seven parents, three teachers, and two administrators.
A careful analysis of the data collected shows that there is a hierarchy among languages used in the community—Turkish, English, and Kurdish. The children, their parents, and their teachers all valued Turkish and English more than Kurdish. While explaining some of their reasons for this view, they discussed the status and functions of each language in society with an emphasis on their functions. My analysis also shows that, although participants devalue the Kurdish language, they still value Kurdish as a tie to their ethnic roots. Another key finding of this study is that policies that appear in teachers’ practices and the school environment seemed to be robust mediators of the language beliefs and practices of the Kurds who participated in my study. School is believed to provide opportunities for learning languages in ways that facilitate greater participation in society and increased access to prestigious jobs for Kurdish children who do not want to live in the village long-term. Related to that, one finding demonstrates that current circumstances make language choice like a life choice for Kurdish children. While Kurds who choose Turkish are often successful in school (and therefore have access to better jobs), the ones who maintain their Kurdish usually have only animal breeding or farming as employment options. I also found that although the Kurdish children that I observed subscribed to ideologies that valued Turkish and English over their native language, they did not entirely abandon their Kurdish language. Instead, they were involved in Turkish- Kurdish bilingual practices such as language broking, language sharing, and language crossing.
