Technological advances in the past decade alone are calling for modifications to the usability of various devices. Physical human interaction is becoming a popular method to communicate with user interfaces. This ranges from touch-based devices such as an iPad or tablet to free space gesture systems such as the Microsoft Kinect. With the rise in popularity of these types of devices comes the increased amount of them in public areas. Public areas frequently use walk-up-and-use displays, which give many people the opportunity to interact with them. Walk-up-and-use displays are intended to be simple enough that any individual, regardless of experience using similar technology, will be able to successfully maneuver the system. While this should be easy enough for the people using it, it is a more complicated task for the designers who are in charge of creating an interface simple enough to use while also accomplishing the tasks it was built to complete. A serious issue that I'll be addressing in this thesis is how a system designer knows what gestures to program the interface to successfully respond to. Gesture elicitation is one widely used method to discover common, intuitive, gestures that can be used with public walk-up-and-use interactive displays. In this paper, I present a study to extract common intuitive gestures for various tasks, an analysis of the responses, and suggestions for future designs of interactive, public, walk-up-and use interactions.

We study an idealized model of a wind-driven ocean, namely a 2-D lid-driven cavity with a linear temperature gradient along the side walls and constant hot and cold temperatures on the top and bottom boundaries respectively. In particular, we determine numerically the response on flow field and temperature stratification associated with the velocity of the lid driven by harmonic forcing using the Navier-Stokes equations with Boussinesq approximation in an attempt to gain an understanding of how variations of external forces (such as the wind over the ocean) transfer energy to a system by exciting internal modes through resonances. The time variation of the forcing, accounting for turbulence at the boundary is critical for allowing penetration of energy waves through the stratified medium in which the angles of the internal waves depend on these perturbation frequencies. Determining the results of the interaction of two 45 degree angle wave beams at the center of the cavity is of particular interest.

Description
This thesis studies the world governing body of soccer, the Fédération Internationale de Football Association (FIFA), by investigating its recent controversial past as a world-leading international non-profit organization. Through examining the organization's beginnings as well as its growth into a nonprofit goliath, this thesis assesses FIFA's actions compared to both the relatively relaxed legal standards in its home country of Switzerland as well as an established set of moral guidelines to analyze the organization's validity in today's complicated global environment. Topics include concerns surrounding FIFA's vast financial reserves, the organization's development programs, its treatment of minorities, and its efforts to prevent organizational transparency that may lead to legitimacy questions in the near future. In the end, assessments of FIFA's validity conclude that the organization falls somewhere between being completely credible and definitively fraudulent, as its actions seemingly are satisfactory legally according to Swiss laws and regulations on paper but questionable morally.

Description
We model communication among social insects as an interacting particle system in which individuals perform one of two tasks and neighboring sites anti-mimic one another. Parameters of our model are a probability of defection 2 (0; 1) and relative cost ci > 0 to the individual performing task i. We examine this process on complete graphs, bipartite graphs, and the integers, answering questions about the relationship between communication, defection rates and the division of labor. Assuming the division of labor is ideal when exactly half of the colony is performing each task, we nd that on some bipartite graphs and the integers it can eventually be made arbitrarily close to optimal if defection rates are sufficiently small. On complete graphs the fraction of individuals performing each task is also closest to one half when there is no defection, but is bounded by a constant dependent on the relative costs of each task.

Description
South Mountain is the largest municipal park in the nation. It is a bundled amenity, providing a series of linked services to the surrounding communities. A dataset of 19,209 homes in 155 neighborhoods within three miles of the park was utilized in order to complete a hedonic estimation for two nearby urban villages, Ahwatukee Foothills and South Mountain Village. Measures of access include proximity to the park, trailhead access, and adjacency to the park. Two regressions were estimated, the first including lot characteristics and subdivision fixed effects and the second using the coefficients for each subdivision as the dependent variable. These estimates describe how the location of a house in a subdivision contributes to its conditional mean price. As a result they offer a direct basis for capturing amenities measured at the neighborhood scale on home values. Park proximity, trailhead access and adjacency were found to significantly influence the price of homes at the 5% confidence level in Ahwatukee, but not in South Mountain Village. The results of this study can be applied to issues of environmental justice and park access in determining which areas and attributes of the park are associated with a high premium. Though South Mountain was preserved some time ago, development and future preservation in the City of Phoenix can be informed by such studies.

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.
