Description
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.

Description
The greatest challenge facing humanity in the twenty-first century is our ability to reconcile the capacity of natural systems to support continued improvement in human welfare around the globe. Over the last decade, the scientific community has attempted to formulate research agendas in response to what they view as the problems of sustainability. Perhaps the most prominent and wide-ranging of these efforts has been sustainability science, an interdisciplinary, problem-driven field that seeks to address fundamental questions on human-environment interactions. This project examines how sustainability scientists grapple with and bound the deeply social, political and normative dimensions of both characterizing and pursuing sustainability. Based on in-depth interviews with leading researchers and a content analysis of the relevant literature, this project first addresses three core questions: (1) how sustainability scientists define and bound sustainability; (2) how and why various research agendas are being constructed to address these notions of sustainability; (3) and how scientists see their research contributing to societal efforts to move towards sustainability. Based on these results, the project explores the tensions between scientific efforts to study and inform sustainability and social action. It discusses the implications of transforming sustainability into the subject of scientific analysis with a focus on the power of science to constrain discourse and the institutional and epistemological contexts that link knowledge to societal outcomes. Following this analysis, sustainability science is repositioned, borrowing Herbert Simon's concept, as a "science of design." Sustainability science has thus far been too focused on understanding the "problem-space"--addressing fundamental questions about coupled human-natural systems. A new set objectives and design principles are proposed that would move the field toward a more solutions-oriented approach and the enrichment of public reasoning and deliberation. Four new research streams that would situate sustainability science as a science of design are then discussed: creating desirable futures, socio-technical change, sustainability values, and social learning. The results serve as a foundation for a sustainability science that is evaluated on its ability to frame sustainability problems and solutions in ways that make them amenable to democratic and pragmatic social action.

Description
In the first thirty years of the XX century, an old literary visual tradition was reborn in a series of new striking visual texts better known as calligrams. They were produced by some avant-garde poets such as Vicente Huidobro, José Juan Tablada, Alberto Hidalgo and Carlos Oquendo de Amat in Latin America, and Juan Larrea, Guillermo de Torre, Francisco Vighi, Luis Mosquera, and others in Spain. However, with few exceptions, the interpretation of those written drawings has caught little attention from literary critics. This research, contrasted to that of Willard Bohn's, is a contribution to the deciphering of such literary art form, designated here as the figurative visual poem. It is a proposal for its visual reading which draws from the fact that this type of text is concretely a drawing formed by written verses. As such, it can be regarded as a plastic writing, combining pictorial and verbal signs in one perceptible configuration on the page. The result of this semiotic operation is a hybrid product in which the iconic forms become symbolic and vice versa. It is in fact, an art object which should be approached as a text that can be seen as well as read. The study leads to the conclusion that Willard Bohn misreads the order in which language and image are articulated in the visual poem identified with the second order semiological system proposed by Roland Barthes, placing preeminence on language over image. This results in reading the avant-garde visual figurative poem in an ekphrastic fashion. Consequently, the role of the image in the system is left in an ambiguous realm at the time of deciphering this hybrid text. Our contribution to re-conducting this undertaking has been equally drawn from a semiotic stance taken from Louis Hjemslev that balances language and image as correlates of a semiotic function. Due to the signaling nature of both, language and figure, a visual poem becomes an iconic metaphor as well as a metaphoric icon, and moreover a self-referential sign, thus justifying its status of an autonomous art.

Description
The uncertainty of change inherent in issues such as climate change and regional growth has created a significant challenge for public decision makers trying to decide what adaptation actions are needed to respond to these possible changes. This challenge threatens the resiliency and thus the long term sustainability of our social-ecological systems. Using an empirical embedded case study approach to explore the application of advanced scenario analysis methods to regional growth visioning projects in two regions, this dissertation provides empirical evidence that for issues with high uncertainty, advanced scenario planning (ASP) methods are effective tools for helping decision makers to anticipate and prepare to adapt to change.

Description
The hagiographic comedy written by Tirso de Molina Los lagos de San Vicente (1607) presents the journey of Santa Casilda in search of the cure of an illness in her blood that affects her. Casilda rejects the medical assistance offered to her by Muslim doctors and miraculously she finds the cure in the Christian world. In this quest, the intellectual and theological evolution of the future saint in defense of the Christian faith is presented. This dissertation will study the resources that Tirso de Molina employs to show the rejection and displacement against the Islamic world represented by a series of erotic behaviors that, in the effort of dramatizing these impertinences they are characterized within a second discourse. Tirso de Molina takes advantage of the hagiographic comedy's discourse nature and the baroque's obscure literary characteristics to express his messages. This dissertation will study in detail how the combination of hagiographic theatrical elements with linguistic expressions are used to convey a subversive discourse that therefore suggests the application of queer theory as a frame of reference. As a result of this investigation it is concluded that Tirso de Molina promotes the hagiographic model and in order to contrast the triumph of the moral Catholic world over the immoral Muslim world the play writer makes references to the nefarious sin.

ABSTRACT As referenced in Navajo ceremonial prayers and songs, "Saad bee hahoozhood jini," it began harmoniously with language. This dissertation examines and celebrates in new ways the meaning of language in Navajo literature. The first chapter is an introduction of this dissertation. I share my personal experiences with language, both English and Navajo, and how it has shaped me to be the person I am today as a Navajo speaker, student, educator, and professional. The second chapter contains an analysis and review of Western ideology of feminism and its place in Navajo society and a comparative study of several works written by Navajo authors, including Laura Tohe, Luci Tapahonso, and Nia Francisco, and how their creative works reflect the foundation of Navajo culture, Asdzaa Nadleehe, Changing Woman. The third chapter presents my own short fiction of Navajo characters living in today's society, a society that entails both positive and negative issues of Navajo life. These stories present realistic twenty-first century environments on the Navajo reservation. The fourth chapter consists of a short fiction written originally in the Navajo language. The story also represents the celebration of Navajo language as it thrives in today's time of tribal and cultural struggles. The sense of it being told in Navajo celebrates and preserves Navajo culture and language. The final chapter is the beginning of an oral narrative presented in written form, that of my grandmother's life story. This introduction of her story also is in itself a commemoration of language, oral Navajo language.

Description
Consumer goods supply chains have gradually incorporated lean manufacturing principles to identify and reduce non-value-added activities. Companies implementing lean practices have experienced improvements in cost, quality, and demand responsiveness. However certain elements of these practices, especially those related to transportation and distribution may have detrimental impact on the environment. This study asks: What impact do current best practices in lean logistics and retailing have on environmental performance? The research hypothesis of this dissertation establishes that lean distribution of durable and consumable goods can result in an increased amount of carbon dioxide emissions, leading to climate change and natural resource depletion impacts, while lean retailing operations can reduce carbon emissions. Distribution and retailing phases of the life cycle are characterized in a two-echelon supply chain discrete-event simulation modeled after current operations from leading organizations based in the U.S. Southwest. By conducting an overview of critical sustainability issues and their relationship with consumer products, it is possible to address the environmental implications of lean logistics and retailing operations. Provided the waste reduction nature from lean manufacturing, four lean best practices are examined in detail in order to formulate specific research propositions. These propositions are integrated into an experimental design linking annual carbon dioxide equivalent emissions to: (1) shipment frequency between supply chain partners, (2) proximity between decoupling point of products and final customers, (3) inventory turns at the warehousing level, and (4) degree of supplier integration. All propositions are tested through the use of the simulation model. Results confirmed the four research propositions. Furthermore, they suggest synergy between product shipment frequency among supply chain partners and product management due to lean retailing practices. In addition, the study confirms prior research speculations about the potential carbon intensity from transportation operations subject to lean principles.

Description
Over the past century in the southwestern United States human actions have altered hydrological processes that shape riparian ecosystems. One change, release of treated wastewater into waterways, has created perennial base flows and increased nutrient availability in ephemeral or intermittent channels. While there are benefits to utilizing treated wastewater for environmental flows, there are numerous unresolved ecohydrological issues regarding the efficacy of effluent to sustain groundwater-dependent riparian ecosystems. This research examined how nutrient-rich effluent, released into waterways with varying depths to groundwater, influences riparian plant community development. Statewide analysis of spatial and temporal patterns of effluent generation and release revealed that hydrogeomorphic setting significantly influences downstream riparian response. Approximately 70% of effluent released is into deep groundwater systems, which produced the lowest riparian development. A greenhouse study assessed how varying concentrations of nitrogen and phosphorus, emulating levels in effluent, influenced plant community response. With increasing nitrogen concentrations, vegetation emerging from riparian seed banks had greater biomass, reduced species richness, and greater abundance of nitrophilic species. The effluent-dominated Santa Cruz River in southern Arizona, with a shallow groundwater upper reach and deep groundwater lower reach, served as a study river while the San Pedro River provided a control. Analysis revealed that woody species richness and composition were similar between the two systems. Hydric pioneers (Populus fremontii, Salix gooddingii) were dominant at perennial sites on both rivers. Nitrophilic species (Conium maculatum, Polygonum lapathifolium) dominated herbaceous plant communities and plant heights were greatest in effluent-dominated reaches. Riparian vegetation declined with increasing downstream distance in the upper Santa Cruz, while patterns in the lower Santa Cruz were confounded by additional downstream agricultural input and a channelized floodplain. There were distinct longitudinal and lateral shifts toward more xeric species with increasing downstream distance and increasing lateral distance from the low-flow channel. Patterns in the upper and lower Santa Cruz reaches indicate that water availability drives riparian vegetation outcomes below treatment facilities. Ultimately, this research informs decision processes and increases adaptive capacity for water resources policy and management through the integration of ecological data in decision frameworks regarding the release of effluent for environmental flows.

Description
Economic development over the last century has driven a tripling of the world's population, a twenty-fold increase in fossil fuel consumption, and a tripling of traditional biomass consumption. The associated broad income and wealth inequities are retaining over 2 billion people in poverty. Adding to this, fossil fuel combustion is impacting the environment across spatial and temporal scales and the cost of energy is outpacing all other variable costs for most industries. With 60% of world energy delivered in 2008 consumed by the commercial and industrial sector, the fragmented and disparate energy-related decision making within organizations are largely responsible for the inefficient and impacting use of energy resources. The global transition towards sustainable development will require the collective efforts of national, regional, and local governments, institutions, the private sector, and a well-informed public. The leadership role in this transition could be provided by private and public sector organizations, by way of sustainability-oriented organizations, cultures, and infrastructure. The diversity in literature exemplifies the developing nature of sustainability science, with most sustainability assessment approaches and frameworks lacking transformational characteristics, tending to focus on analytical methods. In general, some shortfalls in sustainability assessment processes include lack of: * thorough stakeholder participation in systems and stakeholder mapping, * participatory envisioning of future sustainable states, * normative aggregation of results to provide an overall measure of sustainability, and * influence within strategic decision-making processes. Specific to energy sustainability assessments, while some authors aggregate results to provide overall sustainability scores, assessments have focused solely on energy supply scenarios, while including the deficits discussed above. This paper presents a framework for supporting organizational transition processes towards sustainable energy systems, using systems and stakeholder mapping, participatory envisioning, and sustainability assessment to prepare the development of transition strategies towards realizing long-term energy sustainability. The energy system at Arizona State University's Tempe campus (ASU) in 2008 was used as a baseline to evaluate the sustainability of the current system. From interviews and participatory workshops, energy system stakeholders provided information to map the current system and measure its performance. Utilizing operationalized principles of energy sustainability, stakeholders envisioned a future sustainable state of the energy system, and then developed strategies to begin transition of the current system to its potential future sustainable state. Key findings include stakeholders recognizing that the current energy system is unsustainable as measured against principles of energy sustainability and an envisioned future sustainable state of the energy system. Also, insufficient governmental stakeholder engagement upstream within the current system could lead to added risk as regulations affect energy supply. Energy demand behavior and consumption patterns are insufficiently understood by current stakeholders, limiting participation and accountability from consumers. In conclusion, although this research study focused on the Tempe campus, ASU could apply this process to other campuses thereby improving overall ASU energy system sustainability. Expanding stakeholder engagement upstream within the energy system and better understanding energy consumption behavior can also improve long-term energy sustainability. Finally, benchmarking ASU's performance against its peer universities could expand the current climate commitment of participants to broader sustainability goals.

Description
This dissertation addresses the representation of women in the poetry of the Irish poet Thomas Kinsella. Using a variety of theoretical approaches, including historical criticism, French feminist theory and Jungian psychoanalytical theory, I argue that although women are an integral part of Kinsella's ongoing aesthetic project of self-interrogation, their role in his poetry is deeply problematic from a feminist perspective. For purposes of my discussion I have divided my analysis into three categories of female representation: the realistically based figure of the poet's wife Eleanor, often referred to as the Beloved; female archetypes and anima as formulated by the psychologist C.G. Jung; and the poetic trope of the feminized Muse. My contention is that while the underlying effect of the early love and marriage poems is to constrain the female subject by reinforcing stereotypical gender positions, Kinsella's aesthetic representation of this relationship undergoes a transformation as his poetry matures. With regard to Kinsella's mid-career work from the 1970s and the 1980s I argue that the poet's aesthetic integration of Jungian archetypes into his poetry of psychic exploration fundamentally influences his representation of women, whether real or archetypal. These works represent a substantial advance in the complexity of Kinsella's poetry; however, the imaginative power of these poems is ultimately undermined by the very ideas that inspire them - Jungian archetypal thought - since women are represented exclusively as facilitators and symbols on this male-centered journey of self-discovery. Further complicating the gender dynamics in Kinsella's poetry is the presence of the female Muse. This figure, which becomes of increasing importance to the poet, transforms from an aestheticized image of the Beloved, to a sinister snake-like apparition, and finally into a disembodied voice that is a projection of the poet and his alter-ego. Ultimately, Kinsella's Muse is an aesthetic construction, the site of inquiry into the difficulties inherent in the creative process, and a metaphor for the creative process itself. Through his innovative deployment of the trope of the Muse, Kinsella continues to advance the aesthetics of contemporary Irish poetry.
