When listeners hear sentences presented simultaneously, the listeners are better able to discriminate between speakers when there is a difference in fundamental frequency (F0). This paper explores the use of a pulse train vocoder to simulate cochlear implant listening. A pulse train vocoder, rather than a noise or tonal vocoder, was used so the fundamental frequency (F0) of speech would be well represented. The results of this experiment showed that listeners are able to use the F0 information to aid in speaker segregation. As expected, recognition performance is the poorest when there was no difference in F0 between speakers, and listeners performed better as the difference in F0 increased. The type of errors that the listeners made was also analyzed. The results show that when an error was made in identifying the correct word from the target sentence, the response was usually (~60%) a word that was uttered in the competing sentence.

Description
Intracranial aneurysms, which form in the blood vessels of the brain, are particularly dangerous because of the importance and fragility of the human brain. When an intracranial aneurysm gets large it poses a significant risk of bursting and causing subarachnoid hemorrhaging (SAH), a possibly fatal condition. One possible treatment involves placing a stent in the vessel to act as a flow diverter. In this study we look at the hemodynamics of two geometries of idealized basilar tip aneurysms, at 2,3, and 4 ml/s pulsatile flow, at three different points in the cardiac cycle. The smaller model had neck and dome diameters of 2.67 mm and 4 mm respectively, while the larger aneurysm had neck and dome diameters of 3 mm and 6 mm respectively. Both diameters and the dome to neck ratio increased in the second model, representing growth over time. Flow was analyzed using stereoscopic particle image velocimetry (PIV) for both geometries in untreated models, as well as after treatment with a high porosity Enterprise stent (Codman and Shurtleff Inc.). Flow in the models was characterized by root mean square velocity in the aneurysm and neck plane, cross neck flow, max aneurysm vorticity, and total aneurysm kinetic energy. It was found that in the smaller aneurysm model (model 1), Enterprise stent treatment reduced all flow parameters substantially. The smallest reduction was in max vorticity, at 42.48%, and the largest in total kinetic energy, at 75.69%. In the larger model (model 2) there was a 52.18% reduction in cross neck flow, but a 167.28% increase in aneurysm vorticity. The other three parameters experienced little change. These results, along with observed velocity vector fields, indicate a noticeable diversion of flow away from the aneurysm in the stent treated model 1. Treatment in model 2 had a small flow diversion effect, but also altered flow in unpredictable ways, in some cases having a detrimental effect on aneurysm hemodynamics. The results of this study indicate that Enterprise stent treatment is only effective in small, relatively undeveloped aneurysm geometries, and waiting until an aneurysm has grown too large can eliminate this treatment option altogether.

Description
Purpose: This thesis studies the behavior and actions of introverted and extraverted students in regards to preparing for and obtaining a postgraduate position. The purpose of this thesis is to develop an understanding of introverts' and extraverts' approach to the job search process and to provide suggestions to improve the job search process. Methodology: In addition to research of existing literature, a survey was given to students at the W. P. Carey School of Business at Arizona State University, to determine students' job search behaviors, and to recruiters of organizations who recruit from the W. P. Carey School of Business at Arizona State University to determine what recruiters look for in a candidate. Findings - We found that extraverts are more likely to network online than introverts. Secondly, we found that extraverts are more likely to self-promote their strengths to company recruiters than introverts. Thirdly, we found that introverts are more reserved when it comes to discussing their strengths with company recruiters than extraverts. Fourthly, we found that extraverts are more likely to feel as though they successfully represent themselves to company recruiters than introverts. Additionally, we found that the top three behaviors that recruiters look for in candidates include the candidate being energized about the prospects of working for the organization, that the candidate is knowledgeable about the organization, and that the candidate asks questions and introduces him-or-herself at organization information sessions. The three lowest rated behaviors were that the candidate uses live (in-person) networking to connect with the recruiter, that the candidate is reserved when discussing his/her accomplishments, and that the candidate uses online networking to connect with recruiters.

Description
Adam Simons is an Interdisciplinary Studies major at Arizona State University with concentrations in business and music. He is also a member of the alternative rock group RadioDriveBy. RadioDriveBy is a five-piece band based in Arizona that writes, professionally records, and performs its own original songs. This thesis contains a narrative of the planning, execution, and analysis of two albums released by RadioDriveBy. Through his experience and research in managing multiple releases, Simons covers the critical factors for artists to consider when marketing music in today's changing industry. The author divides an album release into five critical components: original music, release structure, artist image, accessibility and availability, and online promotion. This method of analysis develops manageable steps for artists to succeed in the modern music industry. Overall, this thesis is a model and creative project to help understand not only the behind-the-scenes work of RadioDriveBy, but also to provide a framework for other musicians and artists navigating the same path.

Description
White Dove Thrift Shoppes, two stores in Phoenix run by Hospice of the Valley, serve a vital function in the city. These stores allow members of the community to donate and shop while furthering the Hospice cause. Many aspects of the stores run smoothly but there is always room for improvement. While no formal goals have been established, it seems likely that management is looking for ways to increase sales and improve brand awareness. To determine how this can be accomplished, I conducted an external audit interviewed White Dove personnel. To remain competitive, White Dove needs to emphasize its strengths. Among these is the sense of community White Dove provides for its volunteers, customers, and management. The store offers high quality merchandise at a low price, which is essential for the thrift industry. The stores also are quite innovative, which will serve them well in the future. Along with its strengths, White Dove has some areas for improvement. To maximize profitability, it is recommended that White Dove engage in business practices that it is currently not exploring. In terms of marketing, the stores could advertise more within Hospice and the local community. Store tangibles could also be modified to make customers feel more comfortable. Additionally, White Dove should improve training methods for its volunteers and make all volunteers feel appreciated. Finally, managers have indicated that they would like to expand to a younger demographic. To accomplish this, White Dove can utilize ASU students and Greek life. If White Dove can successfully implement these recommendations and continue to highlight its strengths, the stores will remain competitive in the future.

Description
Website usage on both smartphone and tablet devices is rapidly increasing. Website success hinges largely upon how well information on the site is recalled and perceived. The purpose of this study is to explore the question of whether or not the differences in display size and resolution of smartphone versus tablet devices affect the recall of website information. I hypothesize that tablets will produce greater website recall than smartphones, due to their larger screen size and higher resolution which may reduce cognitive strain. During the study, participants viewed a sample website for two minutes on either an iPhone or iPad, and then participated in a brief 20 question memory test to evaluate how well they remembered the website information. Although test scores for the iPad users were about one test point higher than test scores for the iPhone users, the difference was not statistically significant. However, the study was limited by the low sample size (n = 94). This indicates that further research may find that tablets indeed allow for increased recall of certain kinds of website content.

Description
The following paper is a proposal for marketing materials advertising the W. P. Carey Leaders Academy and the experience of business students in Barrett, The Honors College. There is a distinct need for materials that market to and inform prospective students about the experiences and feeling of community that can be attained from being a student in the W. P. Carey Leaders Academy, which is "a community designed exclusively for premier students enrolled in the W. P. Carey School of Business" (W. P. Carey Leaders Academy). The challenge of successfully creating these materials was approached with various methods of data collection and research. The data collection included a review of Arizona State University (ASU), the W. P. Carey School of Business, and Barrett, The Honors College marketing materials, a review of materials from competing institutions, and scholarly articles on the subject of recruitment and marketing. Admission-based data from groups of excelling students was featured. Finally, interviews and surveys with current faculty, staff, and students were conducted to supplement the research and data collection. Analysis of the data provided insight into best practices when marketing from universities and provided an understanding of appropriate methods for marketing this information. The data indicated that creating an online viewbook, like the one currently marketing the entire business school, as well as providing a physical postcard mailer directing students to the online viewbook, would be the best strategy for marketing the W. P. Carey Leaders Academy. The sections of the viewbook this paper proposes to include are Why the W. P. Carey Leaders Academy, W. P. Carey Leaders Academy Experience, Student Life, Academic Success, Involvement, Scholarship, Professional Future, Barrett, The Honors College, For Parents, and Next Steps. Details of the Time, Cost, and Project Personnel follow.

With beauty magazines becoming a prevalent source of information and inspiration for girls and young adults, this creative project analyzed Seventeen Magazine in an attempt to understand its implications. Shortly after its debut, the publication shifted its focus from career and goal-oriented topics to those of fashion and romance. In an effort to construct a visual critique of the segments produced by Seventeen and receive audience response, an interactive installation was created and opened to the public. This paper explains the method used and includes a discussion of audience opinion.
