The inception of the human-powered water pump began during my trip to Maasailand in Kenya over the Summer of 2017. Being one of the few Broadening the Reach of Engineering through Community Engagement (BRECE) Scholars at Arizona State University, I was given the opportunity to join Prescott College (PC) on their annual trip to the Maasai Education, Research, and Conservation (MERC) Institute in rural Kenya. The ASU BRECE scholars that choose to travel were asked to collaborate with the local Maasai community to help develop functional and sustainable engineering solutions to problems identified alongside community members using rudimentary technology and tools that were available in this resource-constrained setting. This initiative evolved into multiple projects from the installation of GravityLights (a local invention that powers LEDs with falling sandbags), the construction/installation of smokeless stoves, and development of a much-needed solution to move water from the rainwater collection tanks around camp to other locations. This last project listed was prototyped once in camp, and this report details subsequent iterations of this human-powered pump.

Description
The field of robotics is rapidly expanding, and with it, the methods of teaching and introducing students must also advance alongside new technologies. There is a challenge in robotics education, especially at high school levels, to expose them to more modern and practical robots. One way to bridge this gap is human-robot interaction for a more hands-on and impactful experience that will leave students more interested in pursuing the field. Our project is a Robotic Head Kit that can be used in an educational setting to teach about its electrical, mechanical, programming, and psychological concepts. We took an existing robot head prototype and further advanced it so it can be easily assembled while still maintaining human complexity. Our research for this project dove into the electronics, mechanics, software, and even psychological barriers present in order to advance the already existing head design. The kit we have developed combines the field of robotics with psychology to create and add more life-like features and functionality to the robot, nicknamed "James Junior." The goal of our Honors Thesis was to initially fix electrical, mechanical, and software problems present. We were then tasked to run tests with high school students to validate our assembly instructions while gathering their observations and feedback about the robot's programmed reactions and emotions. The electrical problems were solved with custom PCBs designed to power and program the existing servo motors on the head. A new set of assembly instructions were written and modifications to the 3D printed parts were made for the kit. In software, existing code was improved to implement a user interface via keypad and joystick to give students control of the robot head they construct themselves. The results of our tests showed that we were not only successful in creating an intuitive robot head kit that could be easily assembled by high school students, but we were also successful in programming human-like expressions that could be emotionally perceived by the students.

Description
37,461 automobile accident fatalities occured in the United States in 2016 ("Quick Facts 2016", 2017). Improving the safety of roads has traditionally been approached by governmental agencies including the National Highway Traffic Safety Administration and State Departments of Transporation. In past literature, automobile crash data is analyzed using time-series prediction technicques to identify road segments and/or intersections likely to experience future crashes (Lord & Mannering, 2010). After dangerous zones have been identified road modifications can be implemented improving public safety. This project introduces a historical safety metric for evaluating the relative danger of roads in a road network. The historical safety metric can be used to update routing choices of individual drivers improving public safety by avoiding historically more dangerous routes. The metric is constructed using crash frequency, severity, location and traffic information. An analysis of publically-available crash and traffic data in Allgeheny County, Pennsylvania is used to generate the historical safety metric for a specific road network. Methods for evaluating routes based on the presented historical safety metric are included using the Mann Whitney U Test to evaluate the significance of routing decisions. The evaluation method presented requires routes have at least 20 crashes to be compared with significance testing. The safety of the road network is visualized using a heatmap to present distribution of the metric throughout Allgeheny County.

Description
There are problems in the breeding practices of miniature horses. This study seeks to determine the source of these detrimental outcomes based on an evaluation of primary attributes selected for by breeders and the lack of genetic information and understanding of these attributes. In order to do this a program model was created to test the effects of selection criteria on breeder behavior and the resultant foals of these crosses. Moving forwards this program will evolve into a database of the equine genome for different horses. This will allow breeders to input their horses and do faux crosses in order to decrease the incidence of negative and detrimental outcomes.

Description
The 1878 Treaty of Berlin sought to address the issue of minority rights in order to stabilize the interests of the Great Powers and the international order; however, in their formulation of a treaty intended to save the imperial component of the system, the European imperial powers not only gave one of their official acknowledgments to nationalist principles, but articulated a critique of the existing notion of state protection for ethnic minorities. This tentative but landmark modification of the imperial model of legitimacy suggested Europe or the world could consist of a host of sovereign nations. In so doing, it recognized the political, and ideological changes that nationalism demanded, changes that would reshape how national groups organize politically, culturally, and militarily. The logic of nationalism demanded that new boundaries, conceived on national lines be drawn, and they were drawn, both within the Austro-Hungarian and Ottoman Empires. The Treaty of Berlin led to the formation of Greater Bulgaria and Albania, and these new nationalities formed a initial answer to the European question of minority groups. The Treaty of Berlin is useful to examine in relation to its better-known and much more radical offspring, the Treaty of Versailles. Differences in the approach of either treaty provide a study in the lasting effects of soft power to resolve international conflict. The Great Powers met in Berlin to address a developing crisis in an attempt to avoid a destabilizing regional conflict through diplomatic and legal means, whereas the Paris Peace Conference met at Versailles to develop new order across Europe in the wake of the Great War. The Treaty of Versailles, sharply chiding the Central Powers as it promulgated a victor's peace, hoped to prevent future war by placing economic burdens on Germany. While the conference at Paris acknowledged the minority position, the overwhelming legal focus went to addressing developing nations and nationalisms in a way that was consistent with the beliefs of old imperial rule. The earlier Treaty of Berlin's relative emphasis on minority questions as logically antecedent to the disposition of nationalism becomes of highest significance in retrospect. It is this focused approach to addressing developing nationalism that makes the Treaty of Berlin an important point of discussion. It provides a precedent for how questions of minority rights should be addressed, and where it falls short of an answer on how conflict might be prevented, it explores how the tensions within the international system can exacerbate one another, as they did in the breakdown of diplomacy and law that to the First World War . This thesis aims to address how the triumph of nationalism as a model of state legitimacy almost immediately gave rise to the question of legal protection of minorities. The minority question only became more urgent as nationalists developed policies that practiced first passive, and then active exclusion of minority groups. While nationalism's relation to democratic rule seemed to solve the problems of representative government, it quickly forced the question of how legitimate representation was determined. Shifting notions of political legitimacy, unworkable empires, and heightened international rivalry formed a widening spiral of crisis that eclipsed the minority question, but this thesis supports the belief that the centrifugal force of conflict came out of the avoidance of addressing minority rights completely. Attempts were made through the twentieth century to mitigate conflict between people groups, but many failed to produce fully developed solutions, while many others favored the status quo, seemingly hoping that the question would answer itself. A study of the early history of the minority rights question helps us understand the national question in the old-new light of the international order and questions of international law. Given the conflicts that have arisen out of the relations between nations and the question of minority rights, the minority question is present in much of today's thinking about human rights and the maintenance of international order. Understanding the origins of minority rights and the factors considered in the early negotiations set to address the problem helps develop a deeper understanding of the of the interactions between nations and people today.

Description
This thesis examines the problems that occur when the politics and practices of social services, specifically maternal and prenatal care, are guided by a distorted understanding of immigration. It compares the politics and practice of this care across two international borders: the U.S.-Mexico and that within Hispaniola. In an ideal world, care would be extended to all individuals regardless of citizenship. However, since every welfare state has its limits at the national border, citizenship matters to both federal governments and medical professionals. Government-provided resources play an integral role in the current immigration debate, as these programs are a collective investment in which all individuals contribute in order to sustain it. The United States developed the welfare state in order to provide necessary resources to those who could not afford it. Its creators did not view these services as a handout, rather as a support for the future workforce of the country. However, health care was and still is not provided on this model of economic and social citizenship. Current U.S. healthcare policy dictates that no one can be turned away in an emergency situation because someone cannot pay their medical bill, including undocumented immigrants. But for immigrant mothers carrying children across the border, maternal and prenatal care does not qualify as an emergency and the federal government aid typically does not extend to them them as citizens. When care is extended to undocumented immigrants in the United States at all, it typically is provided to the child through Medicaid, who is by dint of the Fourteenth Amendment considered a citizen after birth. The relation between the Dominican Republic and Haiti offers a more complex situation, as the idea of birthright citizenship has recently been revoked. Following the Haitian Earthquake in 2010, the only healthcare to which many Haitians had access was across the Hispaniola border. Haitian women who give birth to children in the Dominican Republic are often not evaluated by a doctor until they are entering the delivery process, and even then health-care is complicated by or denied because of racial prejudice and unclear legal situation. In September of 2013, the Constitutional Court of the Dominican Republic issues a new ruling which declared that any immigrant born between 1929 and 2010 without documentation of their own or of their ancestors does not have citizenship, rendering many Haitians born in the Dominican Republic essentially stateless. To be born to a non-citizen mother typically means the child will likely be born with little or no prenatal care, and the mother will receive poor or inadequate care. Prenatal care is one of the most inexpensive elements of a care-model that carries huge returns relative to its costs. All governments would benefit from improved access to maternal and prenatal care because its future citizens who receive such care would be born healthier and have fewer expensive chronic illnesses. Fewer chronic illness among a population would have huge returns on the welfare state because fewer people would be utilizing it for expensive medical treatments. Though most medical professionals condemn the extreme act of denying care to pregnant women or infants (documented or not), the Dominican Republic and the United States have a popular politics that embraces this cruelty, despite the fact that both pride themselves on a multi-ethnic population. It is easy for policymakers to incriminate undocumented immigrants and claim that they are responsible for an illegitimate share of the consumption of the country's resources. Therefore, it seems likely that the host country's perceptions of immigrant natality and maternity help construct a negative image of the immigration "problem" in such a way that laws and policies are designed without accurate rationale. This thesis examines how the United States and the Dominican Republic might improve the relationship between the culture of healthcare and the role of the legal system for immigrants and their children. It seeks to understand the reasons, motivations, and consequences for denying immigrants services on the account of their citizenship status. The social, economic, and health consequences of being an undocumented citizen will be examined. Current legal policy and what political roadblocks and cultural prejudices must be overcome in order to implement a successful policy will be reviewed. Finally, the best practices prenatal care as a national investment will be discussed, as will the problem of cross-cultural perception of natality, maternity, and immigration.

Description
This thesis proposes the concept of soft robotic supernumerary limbs to assist the wearer in the execution of tasks, whether it be to share loads or replace an assistant. These controllable extra arms are made using soft robotics to reduce the weight and cost of the device, and are not limited in size and location to the user's arm as with exoskeletal devices. Soft robotics differ from traditional robotics in that they are made using soft materials such as silicone elastomers rather than hard materials such as metals or plastics. This thesis presents the design, fabrication, and testing of the arm, including the joints and the actuators to move them, as well as the design and fabrication of the human-body interface to unite man and machine. This prototype utilizes two types of pneumatically-driven actuators, pneumatic artificial muscles and fiber-reinforced actuators, to actuate the elbow and shoulder joints, respectively. The robotic limb is mounted at the waist on a backpack frame to avoid interfering with the wearer's biological arm. Through testing and evaluation, this prototype device proves the feasibility of soft supernumerary limbs, and opens up opportunities for further development into the field.

Description
This project charts the development of autobiography as a genre through two pairs of writers: Benjamin Franklin and Jean-Jacques Rousseau of the Enlightenment, and Oscar Wilde and James Weldon Johnson of the fin de siècle, leading into the twentieth century. The Enlightenment thinkers took an Augustinian confessional approach to the autobiography as a genre, revealing their flawed selves to the public in order to make themselves both authentic and virtuous. Through both these writers, autobiography became a way to replace the religious precepts of the Middle Ages, as the flawed self could be redeemed through society in its current historical moment rather than God. Franklin’s autobiography shows how self-making through economic credit is conducive to virtue, while Rousseau turned inward toward a natural goodness lacking in corrupt social relations. Despite their differences, both furthered the development of autobiography as an account of authentic self-making.
The fin de siècle writers fictionalized the autobiography and derived a concept of authenticity that develops from the suffering of social otherness. Wilde praised the poor over the bourgeois in a British Philistine society, while Johnson’s narrator argued for the authenticity of an African-American class striving for economic and social justice. Both writers redeemed suffering through the ideals of the subjective self, a turn inward that resembles Rousseau’s own look into his natural, innermost self. Overall, this project focuses on how the development of the genre between these two pairs of thinkers gives multiple accounts of self-making leading to the social Other becoming an agent for authenticity; how is the self to be read, understood, and made authentic through its imperfections and sufferings? The fictionality of the later works casts an overarching question: is attaining authenticity through autobiography merely fictional?

As robotics technology advances, robots are being created for use in situations where they collaborate with humans on complex tasks. For this to be safe and successful, it is important to understand what causes humans to trust robots more or less during a collaborative task. This research project aims to investigate human-robot trust through a collaborative game of logic that can be played with a human and a robot together. This thesis details the development of a game of logic that could be used for this purpose. The game of logic is based upon a popular game in AI research called ‘Wumpus World’. The original Wumpus World game was a low-interactivity game to be played by humans alone. In this project, the Wumpus World game is modified for a high degree of interactivity with a human player, while also allowing the game to be played simultaneously by an AI algorithm.

Description
My thesis, Arbitrary Samples: A Reflection on Boundaries, is a collection of poetry and prose that examines my individual perspective and interprets experiences that I have had in a way that also relates to collective experiences others may have had. I discuss the importance of art as a metaphoric medium. This is made most evident by the way I use poetry to channel emotions in inclusive manner and the way I use prose to re-evaluate pieces of my identity. I discuss the permanence of art and the ability art has to preserve and express memory. I also examine art's ability to express identity, and the necessity to separate the poetic voice from the personal identity of the writer. I go on to demonstrate the multiplicity of meanings often found in poetry, and the general subjectivity of poetic symbolism. My thesis is broken up into five sections, with five pieces of prose and twenty-four poems total. The topics I explore include, but are not limited to family illness, sexual identity, and domestic violence. The final section demonstrates the process of healing from certain experiences, and the ability to heal through writing. My thesis is a testament to both my English and History majors, and a reflection on the physical and psychological boundaries that exist in our everyday lives.
