The purpose of this applied project was to research and recommend to Phoenix Children’s Hospital (PCH) improvements to their website in order to provide parents whose child has been newly diagnosed with cancer the most clear and appropriate health information. I conducted a study in order to analyze and evaluate the health information content currently provided to parents at PCH. This was done by through qualitative coding methods on both printed documents provided by The Emily Center Library, as well as interviews conducted with three Hematology/Oncology nurses at PCH. Additionally, I researched the current literature surrounding this topic in order to provide a background of information. Based on the results, I recommended that PCH offer parents a comprehensive cancer database in which all provided information would be searchable via their website. This database would also allow them to expand on their two topic focuses: home care and emotional support. Additionally, I recommended that parents are provided information on how to identify credible and non- credible sources on the Internet so that they can find information that is truly medically valuable when searching for information on their own. Lastly, I offered future recommendations that will require continued research so that PCH’s provided health information can continue to grow and improve.
Research and Development of a Blackboard Orientation Course for Face-to-Face Students Taking Online Courses at Washington State University-Everett
Washington State University Everett could benefit from a Blackboard® online orientation course prior to their first credited online course. Research included results from student satisfaction surveys and focus groups. It was determined through both quantitative and qualitative data that students who opt into an online orientation course have the potential for increased satisfaction and success with online coursework throughout their degree-completion experience. Once this determination was made, a fully-functioning Blackboard® orientation course was designed and developed. The course has been tested by faculty and is ready for Fall 2017 deployment as a voluntary online orientation for any student already admitted to WSU Everett.

Diagnostic utility of WISC-IV General Abilities Index and Cognitive Proficiency Index difference scores among children with ADHD
The Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) General Abilities Index (GAI) and Cognitive Proficiency Index (CPI) have been advanced as possible diagnostic markers of Attention-Deficit Hyperactivity Disorder (ADHD). Diagnostic utility statistics were used to test the ability of GAI-CPI difference scores to identify children with ADHD. Participants included an ADHD sample (n = 78), a referred but non-diagnosed hospital sample (n = 66), and a simulated sample with virtually identical psychometric characteristics as the WISC-IV 2,200 child standardization sample. Receiver Operating Characteristic (ROC) analyses were computed to determine the utility of GAI-CPI difference scores to identify children with ADHD. The GAI-CPI discrepancy method had an AUC of .64, 95% CI [0.58, 0.71] for the ADHD sample compared to the simulated normative sample and an AUC of .46, 95% CI [0.37, 0.56] for the ADHD sample compared to the referred but non-diagnosed hospital sample. These AUC scores indicate that the GAI-CPI discrepancy method has low accuracy.
Thermal modeling and investigation into heat extraction methods for building-applied photovoltaic (BAPV) systems have become important for the industry in order to predict energy production and lower the cost per kilowatt-hour (kWh) of generating electricity from these types of systems. High operating temperatures have a direct impact on the performance of BAPV systems and can reduce power output by as much as 10 to 20%. The traditional method of minimizing the operating temperature of BAPV modules has been to include a suitable air gap for ventilation between the rooftop and the modules. There has been research done at Arizona State University (ASU) which investigates the optimum air gap spacing on sufficiently spaced (2-6 inch vertical; 2-inch lateral) modules of four columns. However, the thermal modeling of a large continuous array (with multiple modules of the same type and size and at the same air gap) had yet to be done at ASU prior to this project. In addition to the air gap effect analysis, the industry is exploring different ways of extracting the heat from PV modules including hybrid photovoltaic-thermal systems (PV/T). The goal of this project was to develop a thermal model for a small residential BAPV array consisting of 12 identical polycrystalline silicon modules at an air gap of 2.5 inches from the rooftop. The thermal model coefficients are empirically derived from a simulated field test setup at ASU and are presented in this thesis. Additionally, this project investigates the effects of cooling the array with a 40-Watt exhaust fan. The fan had negligible effect on power output or efficiency for this 2.5-inch air gap array, but provided slightly lower temperatures and better temperature uniformity across the array.
Separate but together: a design history of the Riordan Mansion, an American arts and crafts duplex, Flagstaff, Arizona, 1904
This thesis documents the design history of the Riordan Mansion, and Arts and Crafts style duplex built in Flagstaff, Arizona in 1904 by brothers Michael and Timothy Riordan. The study investigates factors that influenced the design including the Riordan family; the location in Flagstaff, Arizona; the architect, Charles Whittlesey; the Arts and Crafts Movement, and other cultural influences such as religion, naturalism, exoticism, art, and literature. Exterior facade and interior plan, construction materials, technological advances, and furnishings all demonstrate Arts and Crafts characteristics and key principles of the design reform movement. Design reform began in the 1860s with a rejection of the Industrial Revolution's use of machine produced goods, seeking to restore to daily life fundamental values and living standards based upon usefulness and beauty and to promote the importance of the craftsman. The Riordan Mansion (now an Arizona State Park) demonstrates Arts and Crafts principles through its setting and incorporation of local materials; its unified duplex plan, which is unique among grand American Arts and Crafts mansions; its sophisticated interior that utilizes such typical traits as the inglenook, built-in and custom designed furnishings; moldings that repeat from room to room; and collections of Native American and Asian artifacts, an extensive library, paintings and photographs. This home is an extension of its Flagstaff setting to which the Riordans were tied as community leaders.
From Marathon to Athens was inspired by the legend of Pheidippides, a Greek messenger who ran approximately twenty-six miles between the cities of Marathon and Athens in ancient Greece to deliver an important wartime message. According to the legend, he died shortly after completing the journey. The marathon races of today were inspired by his story, though it may be more myth than reality. There is a great deal of inherent drama in the undertaking of such a feat, whether it be a marathon or any other test of strength and endurance. There is the rush of adrenaline when it begins, followed by the excitement and exhilaration of the first few miles. Then, there is a period of settling in and finding a groove - when the runner realizes that there is a long way to go, but is determined to pace him or herself and stay strong. All too often, there is the "wall" that appears about three-quarters of the way through, when it seems that there is no strength left to finish the race. Finally, there is the final push to the finish line - where the runner decides that they are going to make it, in spite of fatigue, pain, or any other obstacle. In this piece, I used a simple melody that was very loosely modeled after a melody from ancient Greece (the tune inscribed on the Epitaph of Seikilos). I used both Phrygian and Dorian modes, which, according to Plato, were most appropriate for soldiers. Throughout the piece, I used different instruments, mostly percussion, to represent the heartbeat of the runner. In the legend, the runner dies - in the piece, the heartbeat becomes very fast and then rather erratic. It then slows and, finally, stops. Though I find the story of Pheidippides inspiring, I wish all marathon runners and athletes of every kind (myself included) a safer and happier outcome!
Coping with school bullying: an examination of longitudinal effects of coping on peer victimization and adjustment
Despite some prevailing attitudes that bullying is normal, relatively innocuous behavior, it has recently been recognized as a serious problem in schools worldwide. Victimized students are more likely to evidence poor academic and semi-academic outcomes, experience social difficulties, and drop out of school in comparison to their non-victimized peers. Although anti-bullying programs have proliferated during the last decade, those aimed at helping children cope with bullying often suffer from a lack of basic research on the effectiveness of children's responses to bullying. The focus of this study was to delineate the ways in which elementary school-aged children typically cope with peer victimization, then to examine which strategies reduce future risk for harassment and associated adjustment problems to inform prevention and intervention program development. A cohort-sequential design was used to examine the effectiveness of children's strategies for coping with peer victimization. The sample included 317 children (157 boys; 49.5% Caucasian, 50.5% Hispanic; M age =10 years 5 months at T1) who were surveyed in the Fall and Spring of two academic years. Confirmatory factory analysis was used to validate the factor structure of the coping measure used and internal reliability was verified. Comparison of means indicated differences in children's coping based upon sex and age. For example, girls tend to cope more emotionally and cognitively, while boys are more behavioral in their coping. Regression results indicated that a number of specific relationships were present between coping, victimization, loneliness, and anxiety. For example, support seeking behavior was effective at decreasing victimization for younger children (fourth graders) who experienced high initial victimization. In contrast, revenge seeking behavior was predictive of increased victimization for both girls and highly victimized students. Problem solving was effective at reducing adjustment problems over time for younger students and, although results for older students were non-significant, it appears to be a promising strategy due to a lack of association with negative future outcomes. Results highlight the importance of identifying influential characteristics of individual children in order for prevention and intervention programs to successfully decrease the incidence and adverse impact of bullying behavior.
Micromachining has seen application growth in a variety of industries requiring a miniaturization of the machining process. Machining at the micro level generates different cutter/workpiece interactions, generating more localized temperature spikes in the part/sample, as suggested by multiple studies. Temper-etch inspection is a non-destructive test used to identify `grind burns' or localized over-heating in steel components. This research investigated the application of temper-etch inspection to micromachined steel. The tests were performed on AISI 4340 steel samples. Finding, indications of localized over-heating was the primary focus of the experiment. In addition, change in condition between the original and post-machining hardness in the machined slot bottom was investigated. The results revealed that, under the conditions of the experiment, no indications of localized over-heating were present. However, there was a change in hardness at the bottom of the machined slot compared to the rest of the sample. Further research is needed to test the applicability of temper-etch inspection to micromilled steel and to identify the source of the change in hardness.
For this thesis a Monte Carlo simulation was conducted to investigate the robustness of three latent interaction modeling approaches (constrained product indicator, generalized appended product indicator (GAPI), and latent moderated structural equations (LMS)) under high degrees of nonnormality of the exogenous indicators, which have not been investigated in previous literature. Results showed that the constrained product indicator and LMS approaches yielded biased estimates of the interaction effect when the exogenous indicators were highly nonnormal. When the violation of nonnormality was not severe (symmetric with excess kurtosis < 1), the LMS approach with ML estimation yielded the most precise latent interaction effect estimates. The LMS approach with ML estimation also had the highest statistical power among the three approaches, given that the actual Type-I error rates of the Wald and likelihood ratio test of interaction effect were acceptable. In highly nonnormal conditions, only the GAPI approach with ML estimation yielded unbiased latent interaction effect estimates, with an acceptable actual Type-I error rate of both the Wald test and likelihood ratio test of interaction effect. No support for the use of the Satorra-Bentler or Yuan-Bentler ML corrections was found across all three methods.
