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
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.

This study examines sustainable development concerns as an essential part of the Costa Rican national identity. Interviews with ecotourism industry workers and an analysis of pertinent news articles shine light on the Costa Rican citizen's perspective of sustainable development, showing that in spite of current initiatives industry workers still have unmet environmental and economic concerns, and that the general public is both passionately interested and personally invested in the topic.

Description
The effects that forensic-themed programs such as CSI: Crime Scene Investigation has on the public's understanding and expectations of the criminal justice system has been a main focus of study in recent years. This phenomenon was coined by the media and termed the "CSI Effect." This study aimed to research the correlations between age, gender, and program-watching habits on potential juries' evidence expectations in court. To do so, 70 people were surveyed and asked a series of demographic questions, as well as questions about how often they watch forensic-themed shows and their experience with the criminal justice system. They were given a mock crime scene scenario and asked about their scientific and non-scientific evidence expectations in this particular case. The most notable results showed that a longer exposure time to forensic-themed programs correlated to high evidence expectations. However, how often viewers watch forensic-themed programs did not seem to affect their evidence expectations. It was concluded that the higher evidence expectations by modern jurors may be due to a combination of the "CSI Effect" and the newly hypothesized "Tech Effect," instead of just being the consequence of the watching too much forensic-themed television.

Abstract Upon review of complex ethnic conflict over the past century in the Great Lakes region, the 2005 Opinion of the Case Concerning Armed Activities on the Territory of the Congo does not properly acknowledge the conflict's complexity, and thus fails in applying customary international law to the allegations under dispute. Both concepts of self-defense and the violation of the duty of vigilance are found particularly restrictive, and their application by the ICJ does not recognize realities. The thesis is laid out to provide context for the dispute, followed by consideration of the historical circumstances that shaped the ethnic, political, and economic reality of the Second Congo War. Finally the paper will begin an inquiry into self-defense and the duty of vigilance as unequipped legal concepts to consider the atypical conflict. I. Introduction II.

Description
In this essay we will explore how five female characters are defined as "bad" or "good" girls based on their interaction and relationship with the patriarchal figures of their text. We will be looking at Goneril, Regan, and Cordelia in Shakespeare's King Lear and Bellatrix Lestrange and Hermione Granger in the Harry Potter series. In order to analyze these five characters in relation to their texts we must first understand what a patriarchal society looks like. Moreover, how a patriarchal society is in the very foundations of both King Lear and the Harry Potter series, which is a result of the culture that each text was published in. By analyzing the actions and words of all five female characters we will be able to see how a patriarchal system is reflected in each text in determining the female characters' fate at the end of those texts.

Description
The difficulty of measuring complex goals within nongovernmental organizations is well detailed in nonprofit management literature. For many years, NGOs have faced obstacles ranging from the technical difficulties of measuring intangible missions to ambiguous or unreliable performance criteria to political issues in the design of measurement systems that cater to diverse stakeholders. But despite the challenges, many nongovernmental organizations and researchers are rising to the challenge to design and implement effective systems of measurement. This thesis outlines the lessons learned from a study of the history and development of performance measurement, existing measurement systems and their implementation, as well as various insights gained from interviews conducted in Spring 2013 with leaders of nonprofit and nongovernmental organizations that are facing or that have faced these and many more obstacles in performance management. With these goals, this paper will strive to answer two main questions. What are performance measures and how do they differ by sector? What are performance measurement systems and why are they important?

Description
J.K. Rowling's Harry Potter series has revolutionized the young adult publishing industry. So popular are the Potter books that they have managed to spawn an empire of merchandise, scholarly literature, movies, and even a theme park, suggesting that Harry Potter is more than just a children's book. In fact, The Harry Potter books, although often categorized under children's literature, contain many elements that make a book distinctly young adult; therefore, by conducting a rhetorical analysis of Rowling's first book, Harry Potter and the Sorcerer's Stone, this thesis will delve deeper into the specifics of theme, literary elements, rhetorical devices, plot, marketing, and characterization to analyze, on a basic level, why Rowling's books appeal to so many, and why they are quintessentially young adult.

My thesis is a creative project. It is a full-length fantasy novel, the first in a trilogy, with the first draft being over 80,000 words. The novel is about a girl named Aster in a world called Aevenora. She is nineteen. Her father just died, giving her a rock-like object with his last breath and telling her to bring it to her great-grandmother, who lives on the other side of Aevenora. Aster and her friends, who join her on her way to her great-grandmother's, are fighting against the Underground throughout the novel. The Underground is a group of people dedicated to regaining wealth, technology, unity, and power that Aevenora had a millennium ago, in the Golden Age. But they have a sinister side to them: they force all magic users (including Aster) to join their cause or die. A theme throughout the novel is Aster's struggle with death. From her mother's death at a young age, to her father's death, to using self-defense and killing humans herself, Aster wonders what the point of death is and why people she loves have to die. This struggle is one philosophers have long grappled with, and one I hope to provide a philosophical answer to by the end of the trilogy. Because novel-writing is a long and involved process, I am submitting only the first draft as my thesis. It is not yet publishable, but I will spend a year or two revising it, then send it to agents and hopefully publish it. I request the embargo option, so that the first draft of the novel will not be released until I have completed the final draft and sent it to agents.
