Description
Sufficient sleep in childhood is fundamental to proper development as well as preventing behavioral or emotional complications later in adulthood (Gregory & Sadeh, 2012; Bruni, 2010). Sleep is controlled by a 24-hour cycle of hormonal regulation termed the circadian rhythm, which is controlled by different environmental inputs such as light (Reppert & Weaver, 2002). Previous research has also demonstrated that light exposure at night can delay the night phase production of specific hormones that promote sleep (Zeitzer, Dijk, Kronauer, Brown, & Czeisler, 2004; Chang, Aeschbach, Duffy, & Czeisler, 2015), which in turn delays sleep onset. Such studies involving the effects that light may have on sleep have focused on adult subjects, however, and it is important to explore this idea in childhood to promote proper development. The first aim of this study was to examine the effects of light exposure in the hour before bedtime on different measures of sleep in middle childhood. The second aim was to determine the genetic and environmental contributions to light exposure and sleep. A diverse sample of 490 twin children was assessed at 8 years of age. Twins followed a week long protocol in which they wore actigraph watches that collected data on both light and sleep. Zero-order correlations with subsequent multilevel regression analyses showed that any light exposure in the hour before bedtime was significantly positively associated with sleep onset latency. Twin intraclass correlations indicated no heritability for light exposure, but did indicate some heritability ranging from 7-66% for the sleep indicators. Overall, these findings regarding the impacts of sleep in childhood build upon an area of research that has only been explored in adulthood. These impacts of light on sleep in childhood suggest that possible interventions ought to be explored for implementation to minimize the long-term effects of altered sleeping patterns in childhood.

Previous research has showed that auditory modulation may be affected by pure tone
stimuli played prior to the onset of speech production. In this experiment, we are examining the
specificity of the auditory stimulus by implementing congruent and incongruent speech sounds in
addition to non-speech sound. Electroencephalography (EEG) data was recorded for eleven adult
subjects in both speaking (speech planning) and silent reading (no speech planning) conditions.
Data analysis was accomplished manually as well as via generation of a MATLAB code to
combine data sets and calculate auditory modulation (suppression). Results of the P200
modulation showed that modulation was larger for incongruent stimuli than congruent stimuli.
However, this was not the case for the N100 modulation. The data for pure tone could not be
analyzed because the intensity of this stimulus was substantially lower than that of the speech
stimuli. Overall, the results indicated that the P200 component plays a significant role in
processing stimuli and determining the relevance of stimuli; this result is consistent with role of
P200 component in high-level analysis of speech and perceptual processing. This experiment is
ongoing, and we hope to obtain data from more subjects to support the current findings.

Description
The Numb gene encodes an adaptor protein that has been shown to play a role in muscle repair, cell proliferation, and the determination of cell fate in satellite cells. Ablation of this gene in satellite cells results in an up-regulation of myostatin and p21, which inhibit the proliferation of myoblasts. These results indicate that the regulation of numb and myostatin could be used to amplify muscle regeneration. This would function as a therapeutic approach to degenerative muscle diseases, such as muscular dystrophy. There are four mammalian NUMB proteins produced through alternative splicing of the Numb mRNA transcript. Only two isoforms are present in adult mammalian muscle, indicating some form of muscle-specific post-transcriptional control of the gene. Additionally, the presence of two polyadenylation sites, and multiple miRNA seed sequences within the 3’ untranslated region (UTR) of mouse Numb indicate the possibility of regulation by a muscle specific miRNA.

Van der Waerden’s Theorem asserts that for any two positive integers k and r, one may find an integer w=w(k,r) known as the Van der Waerden Number such that for every r-coloring of the integers from 1 to w there exists a monochromatic arithmetic progression of length k. This groundbreaking theorem in combinatorics has greatly impacted the field of discrete math for decades. However, it is quite difficult to find the exact values of w. As such, it would be worth more of our time to try and bound such a value, both from below and above, in order to restrict the possible values of the Van der Waerden Numbers. In this thesis we will endeavor to bound such a number; in addition to proving Van der Waerden’s Theorem, we will discuss the unique functions that bound the Van der Waerden Numbers.

Description
While English language education has become increasingly prominent worldwide, countries have adopted various initiatives to increase English language development. One country making a push for English language development is Taiwan; however, current educational practices and values can prove to be challenges in implementing new methods. For example, although Communicative Language Teaching (CLT) methods gained popularity starting in the 1990s, they have been slow to take hold in Taiwan. Additionally, Taiwan’s Ministry of Education is pushing for bilingualism by the year 2030, introducing curricular reforms and new strategies to increase the prominence of English on a social level. In order to analyze current educational methods and practices in Taiwan, as well as predict the efficacy of new strategies, this study focused on gathering the perspectives and experiences of the students themselves. International students were specifically targeted, as they have had exposure to multiple educational environments, as well as firsthand experience applying their English language knowledge in an immersive environment. To gather student perspective, an online survey was made available to Taiwanese international students currently studying in a U.S. university. Respondents were asked multiple-choice questions on curricular focus, as well as short answer questions regarding their educational experiences. Overall, the respondents showed an agreement in regards to the heavy emphasis of reading, writing, and grammar in Taiwan, which they correlated directly with high-stakes exams, particularly the university entrance exam. They also noted the lack of speaking and listening practice, as well as a strong desire to apply English in a communicative sense. These observations hold significant implications for various stakeholders, including teachers, principals, curriculum developers, exam designers, and university admissions.

Innovation Space is Arizona State University’s capstone style project in which upper division students gain real experience in the startup and product development world by solving real-world problems. These problems were presented to my team by sponsor; LG Electronics. Innovation Space uniquely offered an interdisciplinary glance into “real life” in the months before college graduation. Students are placed on teams with designers, engineers, sustainability majors, and business majors to better reflect the real world. As a business student of this program, I was able to gain and share knowledge from my teammates’ distinct backgrounds; as well as gain the interdisciplinary experience that is key to a college education, specifically to a business student. LG Electronics, our sponsor, brought our team the task of expanding their product line in their “wind comfort” business unit. LG Electronics has created a lighter, more efficient motor for a fan; likely as an answer to their dominating fan competitor, Dyson. LG Electronics wanted to see what our team could do to alter the way people cool their homes, and we responded with three original ideas: a modular, non-centralized A/C unit; a hands-free hair dryer; and a portable 360 degree fan. Our team developed the latter product, and named it Torus. The product was developed over the course of August 2018 to May 2019, ending in a working prototype formally presented to the sponsor and industry professionals. On top of this project, I was directed to also analyze the Innovation Space program for its benefits and drawbacks to a business degree from the W.P. Carey School of Business.

RISE Tutoring is an ASU student organization which helps refugee youth achieve academic and personal success through tutoring and mentorship. As a member of RISE Tutoring for three years, the researcher sought to document and analyze the program’s impact on the Phoenix refugee community. It was determined that video documentation, with its ability to capture both visual and verbal testimony, was the ideal holistic approach to assess and share this impact. The researcher hypothesized that RISE Tutoring adds value to the lives of its tutors and students through the multidimensional growth––educational, personal, and cultural––it facilitates for all. Methods of data collection were limited to video and audio, but approval from the Institutional Review Board and consent from all participants were obtained prior to the project’s start. The final video, filmed and edited with the help of a professional videographer, was 20 minutes and 21 seconds in length. The findings derived from the recorded interviews with students, tutors, and community leaders, and from the footage of tutoring and group activities, validated the researcher’s hypothesis. Viewers of the video can witness the bonding of tutors and students; hear the pride in the voices of the tutors and see the passion in their eyes when they speak of their students; and feel the joy and excitement that the program brings to its students’ lives. This project transformed the personal experiences of participants into a collective RISE Tutoring identity which can now be presented, for the first time, to the public. The video also aimed to help RISE Tutoring share its meaningful work and improve its marketing efforts, thereby enabling the organization to recruit more tutors and students, build new partnerships, and fundraise. Through the fulfillment of these goals, the video will empower the organization to effect greater change in the community.

Soccer is a global phenomenon that is played, watched, and enjoyed all over the world. Players and fans are quick to point out that soccer is an international language that unites people of all ethnicities and backgrounds together. However, there has been little research done to find out why, how, or if this is true. In this paper I will demonstrate how soccer is an effective means of communication when barriers of culture, geography, and language exist. To do this I conducted a survey, ultimately across 147 regular soccer players, and took field notes on one on one conversations to gather experiences and opinions regarding how soccer has helped people connect when other means of communication were not viable. By surveying and speaking with regular players, I was able to determine just how effective and in what ways soccer facilitates communication and brings people together. This research is a viable starting point into exploring how a global society can learn from soccer players to break down communication barriers and cooperate better with one another.

YAP/TAZ is the key effector in the Hippo pathway, but it is also involved in many other regulatory pathways to control tissue and organ size. To better understand its regulation and effects in tumorigenesis and degeneration, a preliminary feedback network was created with the species YAP/TAZ, phosphorylated YAP/TAZ, LATS, miR-130a, VGLL4, and β-catenin. From this network a set of ordinary differential equations were written and analyzed for parameter effects. A model showing the healthy, tumorigenic, and degenerative states was created and preliminary parameter analysis identified the effects of parameter modifications on the overall levels of YAP/TAZ. Further analysis is required and connections with the underlying biology should continue to be pursued to better understand how parameter modifications could improve disease treatments.
