Description
The purpose of this project is to raise awareness for children with social anxiety. As a book directed to children around the age of 12, it will give them a character they can relate to, so they can feel less alone. Throughout the story, the main character experiences symptoms of social anxiety and is subject to events that exacerbate those symptoms. Despite her challenges, the main character is able to effectively cope with her social anxiety through her own hard work, and help from her family members, teachers, and peers. The intent is to show children with social anxiety that, contrary to what their disorder makes them feel, they are special and have the capacity to develop skills that are relevant to their talents and interests, and overcome their fears. They should know that parents, teachers, and peers will be there to help and support them and will not judge them as harshly as they suspect. The supporting characters in this story show how a strong support base can influence the success of children with social anxiety. By the end of the story, the main character still has social anxiety, but has gained confidence and her symptoms are less severe. This illustrates that, although social anxiety cannot simply be overcome—that is, it doesn’t go away completely—it can be effectively managed with assistance from close others, and perseverance.

Description
Alzheimer’s Disease (AD) affects over 5 million individuals in the U.S. and has a direct cost estimated in excess of $200 billion per year. Broadly speaking, there are two forms of AD—early-onset, familial AD (FAD) and late-onset-sporadic AD (SAD). Animal models of AD, which rely on the overexpression of FAD-related mutations, have provided important insights into the disease. However, these models do not display important disease-related pathologies and have been limited in their ability to model the complex genetics associated with SAD.
Advances in cellular reprogramming, have enabled the generation of in vitro disease models that can be used to dissect disease mechanisms and evaluate potential therapeutics. To that end, efforts by many groups, including the Brafman laboratory, to generated patient-specific hiPSCs have demonstrated the promise of studying AD in a simplified and accessible system. However, neurons generated from these hiPSCs have shown some, but not all, of the early molecular and cellular hallmarks associated with the disease. Additionally, phenotypes and pathological hallmarks associated with later stages of the human disease have not been observed with current hiPSC-based systems. Further, disease relevant phenotypes in neurons generated from SAD hiPSCs have been highly variable or largely absent. Finally, the reprogramming process erases phenotypes associated with cellular aging and, as a result, iPSC-derived neurons more closely resemble fetal brain rather than adult brain.
It is well-established that in vivo cells reside within a complex 3-D microenvironment that plays a significant role in regulating cell behavior. Signaling and other cellular functions, such as gene expression and differentiation potential, differ in 3-D cultures compared with 2-D substrates. Nonetheless, previous studies using AD hiPSCs have relied on 2-D neuronal culture models that do not reflect the 3-D complexity of native brain tissue, and therefore, are unable to replicate all aspects of AD pathogenesis. Further, the reprogramming process erases cellular aging phenotypes. To address these limitations, this project aimed to develop bioengineering methods for the generation of 3-D organoid-based cultures that mimic in vivo cortical tissue, and to generate an inducible gene repression system to recapitulate cellular aging hallmarks.

Description
In Arizona, there are virtually no established support groups or services for children on the autism spectrum and their families when experiencing the loss of a loved one. This is due to many factors, including the complexity of autism, an inconsistent belief that children with autism are capable of grieving, and a general lack of research conducted on the crossover of children with autism and grief. This proposal is based on the social work strengths perspective, in which I argue that children living with autism are capable of grieving and need support to do so. The way families and practitioners approach grief among children with autism is with individual counseling based on a therapist's discretion, grief books and guides, and virtual communities. I attempt to compile evidence-based and practical activities, interviews with parents and professionals, and my experience in order to recommend effective support for children with autism experiencing loss. My hope is that caregivers will use this material in order to understand and help a neglected population find the language and means to safely grieve.

Description
Background: Noninvasive MRI methods that can accurately detect subtle brain changes are highly desirable when studying disease-modifying interventions. Texture analysis is a novel imaging technique which utilizes the extraction of a large number of image features with high specificity and predictive power. In this investigation, we use texture analysis to assess and classify age-related changes in the right and left hippocampal regions, the areas known to show some of the earliest change in Alzheimer's disease (AD). Apolipoprotein E (APOE)'s e4 allele confers an increased risk for AD, so studying differences in APOE e4 carriers may help to ascertain subtle brain changes before there has been an obvious change in behavior. We examined texture analysis measures that predict age-related changes, which reflect atrophy in a group of cognitively normal individuals. We hypothesized that the APOE e4 carriers would exhibit significant age-related differences in texture features compared to non-carriers, so that the predictive texture features hold promise for early assessment of AD. Methods: 120 normal adults between the ages of 32 and 90 were recruited for this neuroimaging study from a larger parent study at Mayo Clinic Arizona studying longitudinal cognitive functioning (Caselli et al., 2009). As part of the parent study, the participants were genotyped for APOE genetic polymorphisms and received comprehensive cognitive testing every two years, on average. Neuroimaging was done at Barrow Neurological Institute and a 3D T1-weighted magnetic resonance image was obtained during scanning that allowed for subsequent texture analysis processing. Voxel-based features of the appearance, structure, and arrangement of these regions of interest were extracted utilizing the Mayo Clinic Python Texture Analysis Pipeline (pyTAP). Algorithms applied in feature extraction included Grey-Level Co-Occurrence Matrix (GLCM), Gabor Filter Banks (GFB), Local Binary Patterns (LBP), Discrete Orthogonal Stockwell Transform (DOST), and Laplacian-of-Gaussian Histograms (LoGH). Principal component (PC) analysis was used to reduce the dimensionality of the algorithmically selected features to 13 PCs. A stepwise forward regression model was used to determine the effect of APOE status (APOE e4 carriers vs. noncarriers), and the texture feature principal components on age (as a continuous variable). After identification of 5 significant predictors of age in the model, the individual feature coefficients of those principal components were examined to determine which features contributed most significantly to the prediction of an aging brain. Results: 70 texture features were extracted for the two regions of interest in each participant's scan. The texture features were coded as 70 initial components andwere rotated to generate 13 principal components (PC) that contributed 75% of the variance in the dataset by scree plot analysis. The forward stepwise regression model used in this exploratory study significantly predicted age, accounting for approximately 40% of the variance in the data. The regression model revealed 5 significant regressors (2 right PC's, APOE status, and 2 left PC by APOE interactions). Finally, the specific texture features that contributed to each significant PCs were identified. Conclusion: Analysis of image texture features resulted in a statistical model that was able to detect subtle changes in brain integrity associated with age in a group of participants who are cognitively normal, but have an increased risk of developing AD based on the presence of the APOE e4 phenotype. This is an important finding, given that detecting subtle changes in regions vulnerable to the effects of AD in patients could allow certain texture features to serve as noninvasive, sensitive biomarkers predictive of AD. Even with only a small number of patients, the ability for us to determine sensitive imaging biomarkers could facilitate great improvement in speed of detection and effectiveness of AD interventions..

Description
As part of a group project, myself and four teammates created an interactive children's storybook based off of the "Young Lady's Illustrated Primer" in Neal Stephenson's novel The Diamond Age. This electronic book is meant to be read aloud by a caregiver with their child, and is designed for reading over long distances through the use of real-time voice and video calling. While one part of the team focused on building the electronic book itself and writing the program, myself and two others wrote the story and I provided illustrations. Our Primer tells the story of a young princess named Charname (short for character name) who escapes from a tower and goes on a mission to save four companions to help her on her quest. The book is meant for reader-insertion, and teaches children problem-solving, teamwork, and critical thinking skills by presenting challenges for Princess Charname to solve. The Primer borrows techniques from modern video game design, focusing heavily on interactivity and feelings of agency through offering the child choices of how to proceed, similar to choose-your-own-adventure books. If brought to market, the medium lends itself well to expanded quests and storylines for the child to explore as they learn and grow. Additionally, resources are provided for the narrator to help create an engaging experience for the child, based off of research on parent-child cooperative reading and cooperative gameplay. The final version of the Primer included a website to run the program, a book-like computer to access the program online, and three complete story segments for the child and narrator to read together.

Description
Popular culture tends to downplay strong female characters to favor a plethora of male figures that children look up to as heroes. This creates a gender imbalance in exposure to inspirational characters that children can look up to as role models. For our team's creative project, we chose to write and illustrate a children's book mainly targeted at young girls, ages eight to twelve that focuses on the stories of selected female figures of Norse mythology. The five stories in our collection focus on the figures Frigg, Skadi, Elli, Idunn, and Freya and are inspired by the mythology contained in the Prose Edda by Snorri Sturluson and selected medieval texts on the Germanic Lombard tribe. Through our book, Women of Norse Myth: For Little Goddesses, we wanted to introduce children to Norse mythology, a branch of myth that is often overshadowed by more popular mythologies such as Roman and Greek. Additionally, our goal was to bring light to the female figures within Norse myth that are generally given less attention than their male counterparts. Keeping in mind these goals, the stories were adapted from the original myths in a manner that would be suitable for a young audience as well as our aim for female empowerment. The final manuscript contains an introduction to Norse cosmology, introductions to the figures, a glossary of Norse terms used, and the illustrated stories themselves. Together with our combined talents, interests, and goals, Women of Norse Myth: For Little Goddesses was completed, and we hope that someday it can be published and serve as a fun and inspiring storybook for children to read and learn from.

Description
The author examined the relationship between social intelligence and attachment style, specifically how attachment style affects how individuals respond to social intelligence training. Students at the Herberger Young Scholars Academy, a school for the highly gifted, completed an online social intelligence training program through the Social Intelligence Institute and were assessed on a number of items. These items include the Tromso Social Intelligence Scale (TSIS), the Attachment Questionnaire for Children (AQ-C), and a daily diary measure in which they recorded and rated their social interactions day to day. All participants were found to be either securely or insecurely attached, and those that were insecurely attached were further divided into insecure anxious attachment style and insecure avoidant attachment style. It was hypothesized that those with a secure attachment style would have higher initial TSIS scores than those with an insecure attachment style. It was also hypothesized that insecurely attached individuals would benefit more from the social intelligence training program than securely attached individuals indicated by "In tune" scores from the daily diaries, and insecure avoidant individuals would benefit more from the program than insecure anxious individuals indicated by "In tune" scores from the daily diaries. None of these hypotheses were supported by the data, as there was no significant difference between the initial social intelligence scores of the three attachment styles, and none of the variables measured were found to be significant predictors of "In tune" scores. Key Words: social intelligence, social intelligence training, attachment, attachment style, children, adolescents, gifted, IQ, high IQ

Description
Children today are being primed with technology at very young ages, leading to a more digitally focused lifestyle. Tangentially, today's digital culture has led to the increase of online shopping rather than in-store shopping. A group of students at Arizona State University's Innovation Space program, in partnership with Disney Consumer Products, set out to create a children's product that bridged the physical-digital gap, and encouraged outdoor activity. The result of their work was Blitz: a versatile, outdoor gaming console that brings traditional outdoor fun into the digital world. This thesis and paired creative project are an extension of the research and development done by the Blitz team. The purpose of this additional research is to discover how parents and children shop online in to design a website to market and sell the Blitz gaming system. Some of the topics covered include visual design, functionality, user interaction, and marketing tactics. The goal is not to develop advertising tactics to manipulate children, but to find the best ways to design for, and market children's products.

The research objective is to maintain the A4 nanobody stability during dialysis. Various dialysis buffers were tested and compared, including PBS with varying amounts of the detergent, Tween: low, high, none. Furthermore, PBS, Tris, and HEPES, were tested and compared. PBS without Tween was the worst for preserving A4 stability. PBS was determined to be a better dialysis buffer than Tris or HEPES. To find the optimum buffer, other buffers will be tested and compared with PBS; methods such as gravity filtration and lyophilization will be considered as alternatives to dialysis.

Does assisted cycle therapy influence activities of daily living in older adults with Down syndrome?
Description
The aim of this study is to examine the relationship between Assisted Cycle Therapy, leisure time activity levels, fine motor control, and grip force in older adults with Down syndrome (DS), all of which affect activities of daily living (ADL) and therefore quality of life. This is relevant because this particular group is at risk for developing early onset Alzheimer's disease (AD), which presents itself uniquely in this population. The parent or guardian of six participants with DS completed Godin's Leisure Time Exercise Questionnaire and the participants themselves completed Purdue Pegboard and grip force assessments before and after an 8-week exercise intervention. The results were inconsistent with past research, with no change being seen in fine motor control or grip force and a decrease being seen in leisure activity. These findings are indicative of the importance of the effect of fatigue on leisure activity as well as maintaining elevated heart rate throughout exercise interventions.
