Illegal immigration has been a major topic of concern in the last few years in both the United States and the European Union; the policies and practices of border control and the use of detention have often been the center for political debate. Assessing the policies in the United States and the European Union in regards to how 'liberal' each are carried out through practice provides insight to the disparity between policy and practice. The thesis analyzes and compares the discourse used written into the policies, official government guidelines, and reports which focus on the approval and criticism of how the polices are put into practice through the United States and European Union government agencies; whist providing data on recent illegal immigrant trends along the U.S.-Mexican border, as well as the Greek-Turkish border. The results discovered conclude that the European Union writes more 'liberal' discourse into their policy and government guidelines than the United States; the European Union illustrates more concern for fundamental individual rights while carrying out practice along the borders; but is falling short in ensuring that Member States (such as Greece) carry out other policy areas up to European Union standards, in this case the use of detention. The implications of the thesis offer...

The U.S. Southwest Border is associated with highly politicized topics, yet the lived experience of Border Patrol agents is not one of them. Border Patrol agents face risks to their personal safety and security as they attempt to safeguard the national security of the United States while implementing the policies of their organization, which are sometimes at odds with the beliefs and expectations of agents in the field. The purpose of this phenomenological study was to explore perceptions and lived experiences related to the threats and dangers that Border Patrol agents face as they protect the U.S. Southwest Border. The theoretical framework for this study involved McGregor's organizational behavior theory, Janis's groupthink theory, and the bureaucratic dissonance phenomenon. Data collected through semistructured interviews of 11 former Border Patrol agents with direct experience working along the U.S. Southwest Border were inductively coded and subjected to a thematic analysis procedure. On-duty risks, emotional toll, lack of community support, and separation from family are among the stressors for members of this profession. The key findings regarding threats and dangers included: perceived manpower shortage, fear of assaults, the very nature of the job, political and presidential administration conflicts, and lack of mobility (location and career advancements). The recommendations call for greater policy-and decision-maker understanding of the stresses and conflicts facing Border Patrol agents, which could effect positive social change by encouraging policies and regulations to improve job safety and security, and to inform training programs. The promulgation of the findings may contribute to improvements of the morale and safety of Border Patrol agents and enhance security of the United States.

The National Border Patrol Museum (NBPM) in El Paso, Texas presents a view of the history, culture and life along the U.S.-Mexico border that no other museum in the world can offer. Moreover, it provides an opportunity to study and understand people and life in the border through the different forms in which they are representing themselves and how others view them as well. Mean Green: A Visual Cultural Analysis of the National Border Patrol Museum is a visual cultural analysis of the museum that deploys theoretical approaches in the disciplines of visual and cultural studies, Border Studies, Ethnic Studies, discourse analysis, museology, and spatial theory. The objectives of this dissertation are: 1) to study the varied representations, i.e., the hypermasculine white American male and the disenfranchised "illegal" immigrant, that reinforce and challenge the dominant discourse present in the hegemonic state and which are deconstructed when rearticulated in everyday border life; 2) to analyze why the museum represents a homotopia within the limits of a heterotopia; 3) to learn how the museum creates imagined communities through the use of its historical patrimony; 4) to observe the practices in relations of power by employing the notion of panopticon in their design and impose power over its visitors; and finally 5) to understand how the museum is providing a commodification of symbols to promote the hegemonic state. I reference historical events to frame the research for this project: history of the border, especially the El Paso border region, the creation of The Fraternal Order of Retired Border Patrol Officers, the history of the Border Patrol and the NBPM. Altogether, this work shows how the National Border Patrol Museum's exhibits and artifact displays are a reflection of what is happening in the border region.

The vegetation associations in the Eastern San Cristobal Valley of Barry M. Goldwater Range-East (BMGR) were mapped using a combination of field surveys (relevés) and interpretation of aerial imagery in order to contribute to ongoing mapping efforts of Barry M. Goldwater Range-East. Throughout the San Cristobal Valley, 149 relevé samples were collected to characterize the vegetation associations. Seventeen vegetation associations were identified and mapped, including a new Larrea tridentata/Ambrosia dumosa/Grusonia kunzei (Creosote bush-White bursage-Devil's cholla) association. Accuracy assessment of the map was conducted using a contingency table finding the map to be 82% accurate. Route proliferation in the San Cristobal Valley of Barry M. Goldwater Range-East (BMGR) was also mapped and measured using remotely sensed imagery in geographic information systems and modeled with geographical variables in a multivariate regression. Throughout the San Cristobal Valley study site, 6,878 km of unauthorized routes were identified. Geographic explanatory variables distance from slopes greater than 34% (b = -3.252e-5, p<0.001) and the most influential variable distance from unauthorized routes (b = -0.006568, p<0.001) were tested for significance and influence in predicting unauthorized route density. The resulting model, built from the two significant geographic variables in a multivariate regression, was able to explain 57% of the variability in the data. The results from this study have shown that through the use of GIS and remote sensing, unauthorized route density can be predicted by geographic variables which can then be used to make future route management decisions.

This thesis presents an online path planning algorithm developed for unmanned vehicles in charge of autonomous border patrol. In this Pursuit-Evasion game, the unmanned vehicle is required to capture multiple trespassers on its own before any of them reach a target safe house where they are safe from capture. The problem formulation is based on Isaacs’ Target Guarding problem, but extended to the case of multiple evaders. The proposed path planning method is based on Rapidly-exploring random trees (RRT) and is capable of producing trajectories within several seconds to capture 2 or 3 evaders. Simulations are carried out to demonstrate that the resulting trajectories approach the optimal solution produced by a nonlinear programming-based numerical optimal control solver. Experiments are also conducted on unmanned ground vehicles to show the feasibility of implementing the proposed online path planning algorithm on physical applications.

Federal agencies operating along the border in southern Florida include the United States Coast Guard (USCG), United States Customs and Border Protection (USCBP), which is the parent agency for Border Patrol (BP), Immigration Customs Enforcement (ICE), and the National Park Service (NPS). Each agency has its own mission regarding immigration, and conflicts have emerged regarding responsibilities and responses to immigrant landings. The purpose of this study was to identify federal law enforcement perspectives about tactics for responses to Cuban immigrant landings within national parks in southern Florida. This study was motivated by the following research questions: 1.) How do the federal agencies operating along the southeastern border in Florida work together during responses to Cuban immigrant landings within national parks? 2.) What are the perspectives among agency personnel about tactics for response to Cuban immigrant landings within national parks? 3.) What tactics should be emphasized in future responses? The concept of shared mental models (SMM) provided a framework for the research, and data was collected through the Q method. Three factors, or social perspectives, on responses to landings were revealed: 1.) React & Transport, 2.) Protect and 3.) Plan. Implications for managers, limitations and future research is discussed.

In this paper I discuss some of the findings in my study of the encounters between female migrants and immigration enforcement authorities along the U.S.-Mexico border. An objective of the research is to ascertain a more accurate picture of women temporarily suspended in the “intersection” of diametrically opposed processes: immigration enforcement and transnational mobility. Of the many issues that have emerged from this research, family separation is most palpable. This suggests a deeply entrenched relationship between immigration enforcement and the transnationalization of family ties. While this relationship may at first not be obvious, women’s accounts of family separation and family reunification show how, in reconciling these contradictory tendencies, migrant mobility is strengthened, which in turn challenges enforcement measures. In this way, the intersection not only sheds light on how opposing forces (enforcement and mobility) converge but also how each is contingent on the other. This analysis is possible in part through the use of a conceptual intersection of diametrically opposed forces, border enforcement and transnational movement, and thus proves useful in examining the transformative nature of globalized spaces.
