Description
Deconvolution of noisy data is an ill-posed problem, and requires some form of regularization to stabilize its solution. Tikhonov regularization is the most common method used, but it depends on the choice of a regularization parameter λ which must generally be estimated using one of several common methods. These methods can be computationally intensive, so I consider their behavior when only a portion of the sampled data is used. I show that the results of these methods converge as the sampling resolution increases, and use this to suggest a method of downsampling to estimate λ. I then present numerical results showing that this method can be feasible, and propose future avenues of inquiry.

Hiking and Hegemony: Destabilizing the nature/culture and gender binaries through outdoor recreation
Description
This paper explores the contested relationships between nature, culture, and gender. In order to analyze these relationships, we look specifically at outdoor recreation. Furthermore, we employ poststructuralist feminist theory in order to produce three frameworks; the first of which is titled Mother Nature’s Promiscuous Past. Rooted in Old World and colonial values, this framework illustrates the flawed feminization of nature by masculinity, and its subsequent extortion of anything related to femininity — including women and nature itself. This belief barred women from nature, resulting in a lack of access for women to outdoor recreation.
Our second framework, titled The Pleasurable Potential of Outdoor Recreation, cites second-wave feminism as a catalyst for women’s participation in wilderness exploration and outdoor recreation. The work of radical feminists and the women’s liberation movement in 1960s and 1970s empowered women at home, in the workplace, and eventually, in the outdoors; women reclaimed their wilderness, yet they continued to employ Framework One’s feminization of nature. Ecofeminsim brought together nature and women, seeking to bring justice to two groups wronged by the same entity: masculinity. In this context, outdoor recreation is empowering for women.
Despite the potential of Framework Two to reinscribe and better the experiences of women in outdoor recreation, we argue that both Frameworks One and Two perpetuate the gender binary and the nature/culture binary, because they are based upon the notion that women are in fact fundamentally different and separate from men, the notion that nature is an entity separate from culture, or human society, as well as the notion that nature is in fact a feminine entity.
Our third framework, Deer Pay No Mind to Your Genitals, engages poststructuralism, asserting that outdoor recreation and activities that occur in nature can serve to destabilize and deconstruct notions of the gender binary. However, we argue that care must be exercised during this process as not to perpetuate the problematic nature/culture binary, a phenomenon that is unproductive in terms of both sustainability and gender liberation. Outdoor recreation has been used by many as a tool to deconstruct numerous societal constraints, including the gender binary; this, however, continues to attribute escapist and isolationist qualities toward nature, and therefore perpetuating the nature/culture divide. Ultimately, we argue outdoor recreation can and should be used as a tool deconstruct the gender binary, however needs to account for the fact that if nature is helping to construct elements of culture, then the two cannot be separate.

Description
Species survive by adapting to what is demanded by their environment. In constant and fluctuating environments, specialist and generalists should be favored, respectively. However, the costs and benefits of adaptation can depend on a variety of factors that alter the intensity of the specialist-generalist trade-off. We examined flight performance to determine how well flies that evolved in constant and fluctuating temperatures acclimated to hot and cold temperatures. We predicted that flies would perform best at temperatures most similar to the ones the flies evolved at. Best performance was found when rearing and testing temperatures aligned with the temperature at which a genotype had evolved, with the generalist sharing the best and worst performance combination with the constant thermally evolved flies. Interestingly, evolved and reared temperatures had equal impact on flight performance. It was also observed that rearing at 25°C resulted in flies with the best fitness. These results contribute to the specialist-generalist theory and the idea that long term cold development is restricting in terms of range for thermal performance.

Description
Despite regional peace agreements, billions of dollars in aid, and the United Nations’ largest peacekeeping mission in the world, conflict in the eastern Democratic Republic of the Congo persists. This paper explores criticisms made by political scientist Séverine Autesserre, who argues that three simplistic narratives revolving around conflict minerals as a cause, sexual abuse against women and girls as an outcome, and rebuilding central state control as the solution dominate how international interveners view the Congolese conflict. Autesserre further posits that conflict continues because peacebuilding efforts fail to address local dynamics. Using monitoring and evaluation reports of peacebuilding projects in the eastern Congo, primarily from the U.S. Agency for International Development, this paper examines three questions: Do aid agencies have any local peacebuilding projects? If so, do these projects reinforce the dominant narratives? And lastly, do these projects view conflict as a continuum that must be managed through process-oriented objectives, or as a binary phenomenon requiring events-oriented objectives, such as elections? The analysis is based on 10 total reports gathered online, the majority of which are from USAID. Due to a lack of publicly available data and M&E reports on Congo peacebuilding, this collection does not represent a random sample and is not being used to make statistically significant conclusions. Nevertheless, the M&E reports provide a window into how the “rubber meets the road,” so to speak, in terms of how USAID and others view the role of their peacebuilding programs and how to assess programmatic success.
These reports reveal there are certainly some local peacebuilding programs and they do appear to view conflict as a continuum requiring process-oriented goals, such as creating local community mediation organizations. In terms of Autesserre’s three dominant narratives, the results are more mixed. This assortment of seemingly contradictory findings does not mean Autesserre’s arguments are invalid. The USAID Congo Country Strategy document unlocks this apparent contradiction as it explicitly acknowledges Autesserre’s criticisms and appears to move toward finding more nuanced approaches to the conflict. However, at times it still emphasizes the same dominant narratives and state-to-state level approaches. This paper, therefore, concludes that USAID, and potentially others, are in a state of transition between entrenched and evolving narratives. The discord in these evaluations highlights the internal crisis peacebuilders in the Congo are currently facing as they reassess their narratives. In keeping with the self-improving nature of M&E, hopefully these international interveners can move through their narrative transition in an efficient manner, so that they can remain a supportive peacebuilding partner to the Congolese people.

Description
All Walks Project is a student-led nonprofit dedicated to spreading awareness about domestic sex trafficking on college campuses by implementing replicable Student Chapter models on both high school and college campuses. Through the All Walks Project: New Chapter Guide, we explore the effectiveness of peer-to-peer grassroots student organizations, and we provide students with a structured framework to create an effective grassroots campaign against trafficking of their own, with personalized assistance from the All Walks Project's Regional Representatives. This guide explores walks students through the step-by-step process of creating an All Walks Student Chapter. These steps include registering the chapter as a club with the host school, filing a funding request, setting up regular meeting times, connecting with a sister school, becoming educated about sex trafficking, creating a market strategy to fit the specific school, creating an effective student executive board, creating the chapter's social media presence, and registering the chapter with an All Walks Project Regional Representative. This guide also provides the chapter leaders with ideas and guidelines for events, meeting agendas, flyers, and many other relevant resources in order to involve the chapters in official All Walks Project nationwide anti-trafficking campaigns.

Description
A growing number of jobs in the US require a college degree or technical education, and the wage difference between jobs requiring a high school diploma and a college education has increased to over $17,000 per year. Enrollment levels in postsecondary education have been rising for at least the past decade, and this paper attempts to tease out how much of the increasing enrollment is due to changes in the demand by companies for workers. A Bartik Instrument, which is a measure of local area labor demand, for each county in the US was constructed from 2007 to 2014, and using multivariate linear regression the effect of changing labor demand on local postsecondary education enrollment rates was examined. A small positive effect was found, but the effect size in relation to the total change in enrollment levels was diminutive. From the start to the end of the recession (2007 to 2010), Bartik Instrument calculated unemployment increased from 5.3% nationally to 8.2%. This level of labor demand contraction would lead to a 0.42% increase in enrollment between 2008 and 2011. The true enrollment increase over this period was 7.6%, so the model calculated 5.5% of the enrollment increase was based on the changes in labor demand.

Description
Popular culture has a longstanding tendency for being affected by, and reversely affecting, politics. Films, in particular, can exist as either purse “escapism” or heady pathways for political commentary. During the Second World War, governments in both the United States and Great Britain used film as a vessel for their own messages, but after the war ended, the two nations allowed their respective film industries more free expression in commenting on wartime and post-war politics. Film also provided particularly vivid political commentary during, and in the years immediately following, the Cold War. Though film has a longstanding history of being a force for political commentary, the medium’s specific engagement with the Cold War holds particular significance because works produced by the two nations’ film industries paralleled the social trend toward political activism at the time. While films produced in the UK and the United States in the 1960s addressed a wide range of contentious political issues, a huge body of work was spurred on by one of the most pressing political tensions of the time: namely, the Cold War.
The United States and Great Britain were major, allied forces during the Cold War. Despite their allied positions, they had unique politico-social perspectives that greatly reflected their immediate involvement in the conflict, in addition to their respective political histories and engagement in previous wars. As the Cold War threat was a large and, in many ways, incomprehensible one, each country took certain elements of the Cold War situation and used those elements to reflect their varied political social positions to a more popular audience and the culture it consumed.
In turn, filmmakers in both countries used their mediums to make overarching political commentaries on the Cold War situation. This analysis looks at five films from those countries during the 1960s, and explores how each representation offered different, often conflicting, perspectives on how to “manage” Cold War tensions, while simultaneously reflecting their conflicted culture and political decisions. The films analyzed reveal that each country focused on contrasting perceptions about the source of the threat posed by Soviet forces, thus becoming tools to further promote their distinct political stances. While the specifics of that commentary changed with each filmmaker, they generally paralleled each country’s perspective on the overall Cold War atmosphere. The British message represented the Cold War as a very internal battle—one that involved the threat within UK borders via the infiltration of spies the tools of espionage. In contrast, the American films suggest that the Cold War threat was largely an internal one, a struggle best combatted by increasing weaponry that would help control the threat before it reached American borders.

Arizona State University students are currently out of the loop when it comes to hearing about events being held in their community. This is because there is no established service that provides an inclusive list of both on and near campus events. What's worse is that the current methods for event marketing rely heavily on who one knows. Currently, ASU students hear about events through word of mouth, email chains, Facebook pages, and posters around campus. Thankfully, there is now an event marketing method that is available to everyone. UniEvents is a newly developed event service that live-tracks events around ASU's Tempe campus. UniEvents consists of a webpage that accommodates all screen sizes and is accessible by all devices including smartphones, tablets, and desktop computers. The website offers a user-friendly interface and useful features. Students are able to scan through event listings on a calendar or they can use an interactive map to find events nearest to them. Furthermore, UniEvents also offers the option for users to submit events to be advertised through the service. This way, students and organizations can easily spread the word about events on campus. Through UniEvents, ASU students will finally be able to see a conclusive list of upcoming events in one convenient site. Students will be able to save time and hassle by not having to rely on numerous sources to learn about events. UniEvents is committed to help students learn about events and get involved in campus activities!

This research seeks to answer a question—is it possible to change the overall “image” of a city through changes to individual parts of the cityscape? Based on the approach of urban theorist Kevin Lynch the city of Berlin is analyzed through Lynch’s five elements: paths, edges, districts, nodes, and landmarks. Within Berlin, the Unter den Linden, Berlin Wall, Museum Island, Alexanderplatz, and Brandenburg Gate are analyzed through this lens. The time period from 1989-2015 provides a strong example of a case where a city has been able to reinvent its image. This research utilizes historical images and written accounts of the city of Berlin to track changes to the city’s overall “image.” These accounts and images are then contrasted with those of a visit conducted in June of 2015. Ultimately, much is revealed about Berlin through this analysis of its urban landscape. During the 1990s, many sites across the city were re-designed through high-profile international design competitions that show the global interest in rebuilding Berlin after the fall of the Berlin Wall in 1989. A return to pre-20th century architecture, through rebuilding and restoration, is one significant outcome of this process. The struggle of Berlin, and Germany, to come to terms with the history of former Communist East German is another. This research finally reveals that even after almost 30 years of being a reunified city, Berlin has yet to fully understand its Communist history to the same degree it grasps its Nazi past in the cityscape.

Description
This paper explores how marginalist economics defines and inevitably constrains Victorian sensation fiction's content and composition. I argue that economic intuition implies that sensationalist heroes and antagonists, writers and readers all pursued a fundamental, "rational" aim: the attainment of pleasure. So although "sensationalism" took on connotations of moral impropriety in the Victorian age, sensation fiction primarily involves experiences of pain on the page that excite the reader's pleasure. As such, sensationalism as a whole can be seen as a conformist product, one which mirrors the effects of all commodities on the market, rather than as a rebellious one. Indeed, contrary to modern and contemporary critics' assumptions, sensation fiction may not be as scandalous as it seems.
