abstract: Although racial minorities are heavily represented in student bodies throughout the United States, school administrators who work with minority children have been overwhelmingly White. Previous research by race scholars has demonstrated that systems of racial dominance in the larger society are often replicated in schools. However, the role of White school administrators in perpetuating or disrupting racism has not been documented. This study examined the racial attitudes and resulting professional practices of White school administrators who worked in a unique environment. These administrators lived and practiced their profession in towns that lay just outside the borders of the Navajo Nation, a large Indian reservation in the Four Corners region of Arizona, New Mexico, and Utah. Termed border towns, these communities were populated by a large majority of Native Americans, with a heavy representation of Hispanics. This placed White school administrators in the uncommon position of living and working in a place where they were a numeric minority, while simultaneously representing the majority culture in the United States. Twelve White border town administrators in four different communities agreed to participate in the interview study, conducted over a two-month period in 2010 and 2011. Using a semi-structured interview format, the researcher gathered data on participants' racial attitudes and analyzed responses to find common themes. Common responses among the interviewees indicated that there were clear racial hierarchies within border town schools and that these hierarchies were sometimes atypical of those found in mainstream American society. These racial hierarchies were characterized by a dichotomy of Native American students based on residence in town or on the reservation, as well as deferential treatment of White administrators by Native American constituents. The intersectionality of race and socioeconomic class was a key finding of the study, with implications for school administrators' professional actions. Racial attitudes also impacted White border town administrators' actions and sometimes reinforced institutionally racist practices. Finally, results of the study supported several established models of race relations and White identity formation. / Dissertation/Thesis / Ed.D. Educational Administration and Supervision 2011

abstract: ABSTRACT Water resources in many parts of the world are subject to increasing stress because of (a) the growth in demand caused by population increase and economic development, (b) threats to supply caused by climate and land cover change, and (c) a heightened awareness of the importance of maintaining water supplies to other parts of the ecosystem. An additional factor is the quality of water management. The United States-Mexican border provides an example of poor water management combined with increasing demand for water resources that are both scarce and uncertain. This dissertation focuses on the problem of water management in the border city of Ciudad Juarez, Chihuahua. The city has attracted foreign investment during the last few decades, largely due to relatively low environmental and labor costs, and to a range of tax incentives and concessions. This has led to economic and population growth, but also to higher demand for public services such as water which leads to congestion and scarcity. In particular, as water resources have become scarce, the cost of water supply has increased. The dissertation analyzes the conditions that allow for the efficient use of water resources at sustainable levels of economic activity--i.e., employment and investment. In particular, it analyzes the water management strategies that lead to an efficient and sustainable use of water when the source of water is either an aquifer, or there is conjunctive use of ground and imported water. The first part of the dissertation constructs a model of the interactive effects of water supply, wage rates, inward migration of labor and inward investment of capital. It shows how growing water scarcity affects population growth through the impact it has on real wage rates, and how this erodes the comparative advantage of Ciudad Juarez--low wages--to the point where foreign investment stops. This reveals the very close connection between water management and the level of economic activity in Ciudad Juarez. The second part of the dissertation examines the effect of sustainable and efficient water management strategies on population and economic activity levels under two different settings. In the first Ciudad Juarez relies exclusively on ground water to meet demand--this reflects the current situation of Ciudad Juarez. In the second Ciudad Juarez is able both to import water and to draw on aquifers to meet demand. This situation is motivated by the fact that Ciudad Juarez is considering importing water from elsewhere to maintain its economic growth and mitigate the overdraft of the Bolson del Hueco aquifer. Both models were calibrated on data for Ciudad Juarez, and then used to run experiments with respect to different environmental and economic conditions, and different water management options. It is shown that for a given set of technological, institutional and environmental conditions, the way water is managed in a desert environment determines the long run equilibrium levels of employment, investment and output. It is also shown that the efficiency of water management is consistent with the sustainability of water use and economic activity. Importing water could allow the economy to operate at higher levels of activity than where it relies solely on local aquifers. However, at some scale, water availability will limit the level of economic activity, and the disposable income of the residents of Ciudad Juarez. / Dissertation/Thesis / Ph.D. Sustainability 2011

abstract: In this dissertation, I focus on a subset of Native American theatre, one that concentrates on peoples of mixed heritages and the place(s) between worlds that they inhabit. As it is an emergent field of research, one goal of this project is to illuminate its range and depth through an examination of three specific points of focus - plays by Elvira and Hortencia Colorado (Chichimec Otomí/México/US), who create theatre together; Diane Glancy (Cherokee/US); and Marie Clements (Métis/Canada). These plays explore some of the possibilities of (hi)story, culture, and language within the theatrical realm across Turtle Island (North America). I believe the playwrights' positionalities in the liminal space between Native and non-Native realms afford these playwrights a unique ability to facilitate cross-cultural dialogues through recentering Native stories and methodologies. I examine the theatrical works of this select group of mixed heritage playwrights, while focusing on how they open up dialogue(s) between cultures, the larger cultural discourses with which they engage, and their innovations in creating these dialogues. While each playwright features specific mixed heritage characters in certain plays, the focus is generally on the subject matter - themes central to current Native and mixed heritage daily realities. I concentrate on where they engage in cross-cultural discourses and innovations; while there are some common themes across the dissertation, the specific points of analysis are exclusive to each chapter. I employ an interdisciplinary approach, which includes theories from theatre and performance studies, indigenous knowledge systems, comparative literary studies, rhetoric, and cultural studies. / Dissertation/Thesis / Ph.D. Theatre 2011

The research examines what drives Mergers and Acquisitions (M&As) using a theoretical and empirical approach. The theoretical part uses flexible optimal policies which adjust to changes in the market structure following a merger. The empirical part tests the major theoretical predictions to identify determinants of M&As in advanced economies. Chapters 1 and 2 consider M&As among firms in a pollution-intensive sector. Chapter 1 shows that identical polluting firms engage in M&As only if environmental policies are flexible. Chapter 2 shows that the flexibility of environmental policy increases the incentive to merge among heterogeneous firms. In addition, with flexible policy highly polluting firms have the highest incentive to merge than less polluting firms in a given sector. The empirical evidence suggests that the decision of manufacturing firms to engage in M&As is affected by environmental policy and firms may engage in merger deals in anticipation of a change in policy. Chapter 3 shows that with a flexible consumption tax firms in a bigger, more efficient country takeover firms in a smaller, less efficient country. The incentive to merge increases with the efficiency and market size of the host country. The empirical result obtained from 7 OECD countries shows that market size and firm efficiency play a major role in triggering international mergers.

Migration has become a topical theme both in academia and in public discourses across the media which have contributed to create a highly political and visual 'migrant subject'. However, the highly mediatized figure of the migrant has left crucial aspects of migration underrepresented and unrecognised. What is normally concealed and left to the margins of public debate is the individual experience of the protagonists, their imaginative lifeworlds and the complexity of their stories. This practice-based research has centred its inquiry on the relationship between the lived experiences and the imagination of past, present and future existential possibilities, by engaging three Egyptian migrants through the creative processes of theatre improvisations, storytelling practices, participatory photography, collaborative filmmaking and animation. It recognizes the fundamental role that imagination and future existential possibilities play in people’s perceptions of reality, in their decisions and actions, and finally in the way they narrate their experiences. In order to better understand how individuals make their choices, interact with each other, understand themselves and the world around them, I have argued that we need to take into account their biographies and imaginative inner lives as the ways people retell their stories allow space for contradiction, feelings of ambivalence and uncertainty, unlaced and unfinished thoughts and existential dilemmas. Imaginative realms of existence are ever-changing and ungraspable, posing a challenge to conventional methodologies in the social sciences which rely heavily on observation, interviews and text. The thesis is divided into two parts. By using the ethnographic material that emerged during fieldwork and from the creative processes, in the first part I look at the role imagination and the future play in Ali’s, Mohamed’s and Mahmoud’s relationships to their origins, and to their decisions and experiences of illegally crossing the Mediterranean Sea in order to reach Milan (Italy). The second part describes and reflects upon the performative and audio-visual collaborative practices that involved my participants in producing their own narrations and theoretical reflections on their experiences, aspirations and memories. It is thanks to the ‘subjunctive possibilities’ enabled by performative improvisations, creative storytelling and the animation that my participants and I could explore their mnemonic and imaginative processes. Finally, the thesis concludes by arguing for social research to engage participants in more collaborative and creative practices in the study of migration, as a necessary way of involving the protagonists in producing the questions and counter-narratives that reclaim their acts of struggle and their creative imaginative abilities to contrast objectifying political discourses and exclusionary legal and bureaucratic procedures.

Pluralities of people s crossings of the Mekong Thai-Lao border occur as locals subvert, reject, ignore, and embrace the logic of the national border. From a state-centric point of view, the everyday movements of these people, who rely mainly on a subsistence economy and have their own modes of crossing, are undocumented. I argue that people s mobility co-exists with the practice of sedentary assumption. The aim of this thesis is to promote theory related to the Third Space in Borderland Studies by the presentation and analysis of people s pluralities in border-crossings. The borderland area of Khong Chiam (Thailand)-Sanasomboun (Lao PDR) is the location of an in-between state in which spatial negotiations, temporal negotiations, and negotiations of political subjectivities contribute to the nature of mobility in the Third Space. To achieve the objective of this thesis, ethnographic methodology was used over six months of fieldwork from March to September 2016, and included participant observations, interviews and essay-readings that involved 110 participants in the borderland site. People s movements across the Mekong River border occur daily without formal state approval. From the perspective of the Thai Ban, the river is a lived space in which they catch food and use for transport. However, their interpretation of the Mekong as the state boundary does not completely disappear. This thesis examines the everyday banal pluralities of the Thai Ban s border-crossings by weaving together the three concepts of space, temporality, and negotiations of political subjectivities. The spatial and temporal negotiations involved in the border-crossings shape and are shaped by this other interpretation of the Mekong as a lived space, and different political subjectivities contribute to the pluralities of the crossings. The presentation of these pluralities of border-crossings adds to Borderland Studies specifically and the social sciences in general in the development of an understanding of the Third Space. As this thesis focuses on people s mobility at quasi-state checkpoints and in areas along the Mekong Thai-Lao border with no border checkpoints, it is suggested that future research examines the everyday practices of border-crossings at land borders.

Electrokinetic phenomena in liquid foams is at a junction between two areas. On one side is the investigation of liquid foam drainage, and on the other side is electrokinetics of surface driven flow on solid-liquid interfaces. However, the electrokinetic phenomena in liquid foam films significantly lack understanding. Therefore, the novelty of the thesis is to address the mentioned gap in three stages. The outcome has potential applications in a novel separation approaches of biological molecules such as proteins and DNA. In the first stage, the electrokinetic flow of a sufficiently thick (180 μm) free liquid film was investigated using cationic and anionic surfactants by confocal micron-resolution particle image velocimetry (μ-PIV). The reverse of the surface charge resulted in a shift in charge of the electrical double layer at the free liquid film interface, which caused the direction of the electroosmotic velocity to reverse. In each surfactant type used, the fluid velocity profiles were measured at different depths of the free liquid film (different z-planes). It was found how the fluid velocity varied with depth. Numerical simulations of the electroosmotic flow in the same system were also performed using Finite Element Method to understand the flow dynamics. A reasonably good agreement was found between the numerical simulations and the experimental results validating the model. In the second stage, instead of flow visualisation particles, rhodamine B (RB) and fluorescein isocyanate (FICT) dye were added to the free liquid film. Under the initial conditions of pH 7.2, RB is a neutral dye, and FICT has a -2 charge. Under an imposed electric field pH variations were detected and an interesting flow profile was observed. The CFD model developed earlier (stage one) was modified to include the local pH variation. The behaviour of the simulated pH had a good agreement with the behaviour of the FICT. Further confirmation of local pH variation was undertaken using extra new experiments which also showed a good agreed with the simulation. In the third stage, a liquid foam electrokinetic separation chamber was designed to extend the study to include practical applications. The first challenge was to achieve a stable foam under external electric field. A polymer-surfactant mixture can solve the stability problem. However, the mixture of polymers required an alkaline pH (>9) condition for the polymer mixture to be soluble in the aqueous system. Lectin and tetramethylrhodamine goat anti-rabbit (IgG) protein mixture with different molecular mass to charge ratio (50 kDa and 150 kDa) were injected near the anode. The system was monitored in three location: (a) in a vicinity of the injection region, (b) between the two electrodes and (c) in a vicinity of the cathode. In the region (a), a decay of the luminescence intensity of the fluorescein of the two proteins was noted with varying rate. In region (b), an increase followed by a decrease in fluorescein intensity of the proteins was observed again at a varying rate. In region (c), an increase of the dye concentration was observed and again at a different rate. The observed difference was caused by difference of the electrophoretic velocity of the two proteins. The setup proved that proteins could be separated based on their electrophoretic mobility inside a liquid foam. The findings from the thesis show the ability to manipulate fluid flow within a free liquid film, and inside a liquid foam system by an external DC electric field, is not only interesting academically but has potential application in a novel separation approach of biological molecules and beyond. The result show, with the correct surfactant formulation, it possible to make a stable foam under an electric field which can be set up for separation of proteins using foam electrokinetics.

abstract: In The Archive and the Repertoire, Diana Taylor discusses how performance, gestures, resistances within a community holds an embodied memory and enacts the transmission of knowledge within that community. Taylor discusses how this embodied memory is alternative to the written archive of history, history of interaction, history of meaning, history of language. Through the consideration of performance, Taylor urges her reader to reconsider oral and performative transmission of culture, knowledge, customs, traditions, and resistance. This project considers whether this reconsideration can be extended or expanded to oral and performative transmission of law within a community. Specifically, this research explores the conflict between the project of nationality and the reality of social organizing on a community/collective level. It asserts that this conflict is manifested most dramatically within border communities. The dissertation examines how the role of written law in the borderlands divides land and inhabitants and reconstructs a new understanding of the borderlands through oral histories and resistance by border communities. The overall goal of the dissertation is to challenge current scholarship to address the conceptual and sociopolitical task of a world in which legal representations and abstractions supersede the complex reality of community relations. As legal anthropologist Sally Falk Moore identified, we must consider carefully whether or not law controls the social context and what this means for our own definitions of community, what are the boundaries and borders of communities, and the seemingly limitedness of social interaction that becomes based on such legal definitions. The dissertation analyzes the defining disconnect of law from the social context that manifests itself amongst border communities along the U.S.-Mexico border. By exploring how law creates, sustains, molds, and connects the phenomenon of sovereignty, economy, and international borders, we can begin to understand how actions of border communities along the U.S.-Mexico border define the disconnect of law from the social context by redefining community itself. / Dissertation/Thesis / Ph.D. Justice Studies 2012

Konflikterna i södra Afrika under 1900-talets andra hälft är något som idag är främmande för många och som direkt för tankarna till apartheid regimen. Hårt pressat av omvärlden på grund av deras raspolitik kämpade Sydafrika i många år en oftast anonym konflikt mot kommunistiska styrkor som hade stöd från Kuba och Sovjetunionen. Under vissa perioder, speciellt mot krigsslutet, eskalerades stridigheterna och stora konventionella operationer bedrevs långt in i Angola för att hindra framfarten av fientliga styrkor.  Sydafrikas användandet av stridsflyg kopplas i denna studie till John A. Warden III:s teorier om hur luftmakt bör användas. Warden är mest känd från perspektivet att hans teorier var grundläggande i planerandet av Gulfkriget i Irak och andra amerikanska luftoffensiver under 1990- och 2000-talet. I detta arbete undersöks i hur stor utsträckning det är möjligt att finna spår av Wardens luftmakts-teorier i Sydafrikas gränskrig. Resultatet av studien visar, genom en analys, hur enskilda händelser och operationer korrelerar med utvalda begrepp ur Wardens teorier. Däremot finns det inga indikationer som pekar på att det större strategiska perspektivet överensstämmer med Wardens större konceptuella idéer. / The conflicts in southern Africa during the second part of the 20th-century are today a piece of half-forgotten history that immediately invokes images of the South African apartheid regime. Under immense pressure from the outside world, South Africa fought a conflict against a communist force that enjoyed support from states such as Cuba and the Soviet Union. The conflict tended to rise and fall in intensity and during the latter part of the war; conventional operations were executed deep into Angolan territory in order to halt the enemy offensive. In this study the South African use of fighter jets are compared to John A. Warden III’s theories on how an air war should be fought. Wardens claim to fame came with the Gulf war and the following conflicts that used methods that spawned from his ideas on how airpower should be used. This essay examines to what extent Wardens ideas are applicable to the South African border war.  The analysis shows that specific events and operations correlate with Wardens ideas, however there are no significant signs of what might be interpreted as operations of the type of conceptual thinking that Wardens uses on the larger, strategic scale.

This thesis is a study on solutions for cross-border insolvency of multinational corporate groups, with particular reference to the EU Regulation on insolvency proceedings recast 2015 (EIR Recast). Multinational corporate groups are important players in the modern business world; how to treat them in cross-border insolvency context has been hotly debated. The main issue is how to preserve the value of the group under circumstances where member companies in the same group are in more than one country and subject to more than one set of insolvency law. The existing solutions include substantive consolidation, procedural consolidation proposed by cross-border insolvency law scholars, market/hybrid legal solutions aiming to avoid group-wide insolvency, and the EIR recast which unprecedentedly provides 'group coordination proceedings' to respond to this issue as a procedural cooperation framework. All these solutions will be examined in this thesis in the light of insolvency law/cross-border insolvency law theories and multinational enterprises theories. The aim of this thesis is to examine the existing solutions for cross-border insolvency of multinational corporate groups on the basis of a combination of insolvency law/cross-border insolvency law theories and multinational enterprises theories. The thesis starts from theoretical grounds of corporate rescue and argues that preservation of going concern value and respecting entity law are the goals of corporate rescue law. It further considers theories regarding multinational enterprises and its implications on developing cross-border insolvency solutions for multinational corporate groups. With an understanding of relevant theories, the thesis examines the procedural consolidation solution which focuses on insolvency jurisdictional rules. The result is that procedural consolidation may not be in line with the reality of how the groups are operated and may not provide certainty to the creditors and market. The thesis moves on to examine the market/hybrid legal solutions which purport to be able to avoid group-wide cross-border insolvency. It shows certain merits of these solutions and also reveals the limitations and uncertainty of them. Finally, it argues that a general insolvency cooperation framework- the new group coordination proceedings- is desirable to work as an alternative to the above-mentioned solutions with improved certainty. The thesis tries to improve the utility of the proceedings by providing a recommendation to one of their main weaknesses-the opt-out mechanism.
