Characterization And Kinetic Analysis Of Novel Di-Aryl-Substituted Isoxazole Hydrazone Analogues At The L-Cystine/L-Glutamate Exchanger System Xc-, Jayme Lee Hartzell

Graduate Student Theses, Dissertations, & Professional Papers

The System xc- antiporter is plasma membrane transporter that mediates the exchange of extracellular L-cystine with intracellular L-glutamate. This exchange is significant within the context of the CNS because the import of L-cystine is required for the synthesis of the antioxidant glutathione, while the efflux of L-glutamate has the potential to contribute to either excitatory signaling or excitotoxic pathology. Changes in the activity of the transport system have been suggested to contribute to the underlying pathological mechanisms of a variety of CNS disorders, one of the most prominent of which is it highly enriched expression glial brain tumors. In an …

The Bear In The Footprint: Using Ethnography To Interpret Archaeological Evidence Of Bear Hunting And Bear Veneration In The Northern Rockies, Michael D. Ciani

Graduate Student Theses, Dissertations, & Professional Papers

Archaeological evidence of prehistoric bear hunting and bear veneration in the northern Rocky Mountains and northwestern Plains is presented. Ethnographic documents and the writings of trappers, traders, and explorers are assessed in order to establish an interpretative framework to help decipher archaeological contexts in the region that include bear remains and rock art depicting bears. Examining prehistoric archaeological contexts in Montana and Wyoming within this framework suggests evidence of bear hunting and veneration similar to the regional ethnographic record. Data trends imply there may be a relationship between such sites and variables like site location, seasonality, function, and age. Contexts …

Assessing The Determinants Facilitating Local Vulnerabilities And Adaptive Capacities To Climate Change Impacts In High Mountain Areas: A Case Study Of Northern Ladakh, India, Kimiko Nygaard Barrett

Graduate Student Theses, Dissertations, & Professional Papers

Climate change is increasingly redefining the dialectic exchange between human systems and ecological processes. While the rhetoric of climate change is articulated within broad arenas of governance and policy, the realities of climate change are experienced at the local scale. Effective adaptation measures must therefore be commensurate with local resources, needs and objectives while remaining aligned with larger decision-making efforts. The impacts of climate change are heterogeneous and vary with geographic context. Biophysical parameters interface with socioeconomic and political forces to greatly influence the outcome of climate-related risks at the local level. In the high mountains of the western Himalayas …

A Treatise On The Assault On Language Sovereignty In The United States: History, Education, And Implications For Policy, Annie Thornburg Oakes

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation examines the revitalization of endangered Indigenous languages in the United States in relation to the concept of sovereignty. I investigate historical reasons for language destruction in the United States as a means of understanding the mechanism used in conquest and the long-range effects on the educational system. I use the term "language sovereignty" to reflect the right of tribal organizations in the US to assert the use of traditional languages as a means of self-identifying as distinct sovereign nations. I draw from initiatives in Hawaii and Europe to demonstrate how regional and linguistic minority languages have been revitalized …

Life, Liberty, And The Pursuit Of Free Markets: Alec's Populist Constructions Of "The People" In State Politics, Anne Sherwood

Graduate Student Theses, Dissertations, & Professional Papers

The American Legislative Exchange Council, or ALEC, has been championing neoliberal and neoconservative bills relatively unnoticed in statehouses across the country for years. Using the populist frame, I contend that ALEC creates a new subject position for its corporate and legislative members as small business owners and virtuous entrepreneurs. This rhetoric is also on display in Wisconsin, where Governor Scott Walker utilizes populist rhetoric to constitute "the people" as workers.

The U.S. National Park Service: Organizational Adaptation In An Era Of Complexity, Uncertainty, And Change, Anna Christina Mills

Graduate Student Theses, Dissertations, & Professional Papers

Conservation agencies worldwide are facing rapid, volatile social and ecological change, which is especially problematic for bureaucratic, hierarchical conservation organizations that are designed to be stable and resistant to change. The current science and management paradigm based on Progressive era ideology is proving to be inadequate to deal with this change, and the need for a new paradigm that embraces complexity and uncertainty in our social ecological systems is emerging. The National Park Service (NPS) is one of these organizations that has acknowledged the need to better adapt to a changing environment. An external science committee recommends in Revisiting Leopold: …

Stakeholder Perspectives Regarding The Ecosystem Services Produced By The Frank Church - River Of No Return Wilderness In Central Idaho, Benjamin Thomas Irey

Graduate Student Theses, Dissertations, & Professional Papers

Wilderness management is directed by policy and legislation that mandates protection of the values associated with wilderness character. However, there is ample evidence to suggest that wilderness benefits society in many ways, beyond the values associated with wilderness character. If that is the case, then failure to account for those values will lead to socially inefficient management decisions. The Frank Church - River of No Return Wilderness (FC-RONRW) in central Idaho was selected as a case study region in which to test the hypothesis that society derives a multitude of benefits from wilderness in addition to those associated with wilderness …

A Quantitative Study With Online Collaborative Learning In A Computer Literacy Course, Kevin Engellant

Graduate Student Theses, Dissertations, & Professional Papers

Collaboration, along with critical thinking, communication and creativity, is one of the four C's identified in the Partnership for 21st Century Skills Framework. The word collaboration is becoming a common part of many conversations. This study explored which type of learning instruction, collaborative learning in an online environment or individual learning in an online environment, is the most effective in a beginning online computer literacy course. The problem underlying this study was that despite the popularity of collaboration in education, many educators are not properly implementing an environment that encourages and supports effective collaboration. The purpose of this quantitative study …

Stepping Outside: The Shifting Subjectivities Of Post-Romantic Poetry, William John Soloy

Graduate Student Theses, Dissertations, & Professional Papers

This investigation traces the arc of fracturing and exteriorizing subjectivities in the post-Romantic poetries of Modernism and Postmodernism, ultimately considering the state of contemporary Postmodern subjectivity after the Language Poets. Focusing primarily on T.S. Eliot, John Ashbery, and Christian Hawkey, the thesis argues that the I/Other split associated with Romantic poetry’s idealized Othering of nature performs a major shift with the interiorizing fragmentation of the speaker(s) in “The Love Song of J. Alfred Prufrock.” The anxiety produced by this claustrophobic, internal splitting of voices reaches critical mass in the chorus of difficult-to-trace speakers of “The Waste Land,” causing a breach …

Women And Horses: Three Centuries Of Patriarchal Control In British And American Literature, Kaitlynn Hanna Hirst

Graduate Student Theses, Dissertations, & Professional Papers

Both literary representations of horsewomen and critical responses to such characterizations have largely failed to expose the full complexity of the cultural constraints brought to bear on women’s interactions with horses. In this thesis therefore I will argue that in response to feminist activity to dispel stereotypes of any group of women, the long development of strong, capable representations of women on horseback spanning the nineteenth through the early twenty-first century prove to be little more than repetitive archetypal images which serve to reaffirm patriarchal controls in western culture. If only threaded together by the ways the literary figure of …

Commodity Or Dignity? Nurturing Managers' Courtesy Nurtures Workers' Productivity, Montana Rafferty Moss

Graduate Student Theses, Dissertations, & Professional Papers

Dignity is the measure of people's worth determined through social interactions (Neal, 2012). As people must enjoy core capabilities to possess dignity (Ward & Syversen, 2009), work is one activity through which core capabilities provide a sense of worth (Venkatapuram, 2013). Workplace managers must enact dignity affirming discourse so their workers perceive ownership of core capabilities that afford a sense of worth and fulfillment. Dignity disaffirming (or violating) discourse obstructs core capabilities, leaving work unsatisfying and workers physiologically, psychologically, and emotionally damaged. Not only do such people suffer, but so do their organizations (Ghoshal, 2005). This study reveals that women …

Second-Dialect Acquisition In Southwestern Pennsylvania, Lisa Marie Sprowls

Graduate Student Theses, Dissertations, & Professional Papers

This thesis presents an analysis of second-dialect acquisition of Pittsburgh English phonological features. Pittsburgh English is the dialect spoken in southwestern Pennsylvania. There are two phonological features unique to the dialect: (i) the [ɔ] realization of the low-back vowel merger and (ii) monophthongal /aw/ (Johnstone et al. 2002). The current study is based on speech data collected from nine participants, native speakers of other dialects of English who now live in southwestern Pennsylvania. This analysis shows that these two phonological features can be acquired. This is the first study to examine Pittsburgh English as a second-dialect. Participants read a word …

Third Party Effects Of Affectionate Communication In Family Subsystems: Examining Influence On Affectionate Communication, Mental Well-Being, And Family Satisfaction, Timothy M. Curran

Graduate Student Theses, Dissertations, & Professional Papers

This study examined the links between affectionate communication expressed within family dyads and affectionate communication expressed among other dyads, as well as individual reports of satisfaction with family life and mental well-being. Overall, the study showed that a child’s report of affectionate communication exchanged in the child/father subsystem is associated with mother’s satisfaction with family life. Additionally, mother reports of affectionate communication exchanged in the spousal relationships were positively associated with child reports of child/father affectionate communication exchanged. Finally, both perceptions of affectionate exchange in dyads outside and inside of one’s direct experience correlated with satisfaction with family life and …

An Alloy Of Steel And Information And Communication Technology (Ict): Does It Facilitate Trade?, Volodymyr Shemayev

Graduate Student Theses, Dissertations, & Professional Papers

The advances in Information and Communication Technology (ICT) over the last 20 years, particularly proliferation of the Internet, fixed-telephones, and mobile phones, have significantly reshaped the way modern firms do their business. The economic literature suggests that ICT could be a potential trade-enabler, given its ability to reduce costs of search and communication between trade partners. This research intends to examine whether ICT affects countries’ capabilities to export steel and its articles. To estimate the impacts of the Internet, mobile phones, and fixed-telephones on bilateral trade flows in the steel industry, I apply various gravity model specifications, including those capturing …

Juvenile Age Estimation Using Cranial Ratios, Rachel Lucille Fife

Graduate Student Theses, Dissertations, & Professional Papers

Age estimation of juvenile crania can be accomplished with accuracy from dentition. In the absence of dentition there is not a sufficient substitute for reliably establishing age. I offer an alternative means of age estimation using cranial ratios, which are informative because of the differential growth rates of the orbits, facial bones, and cranial vault. I took 40 measurements from 76 crania and statistically analyzed ratio relationships among them to produce equations for age estimation. Accuracy of age estimation using cranial ratios increases with the number of measurements used. Ratios reduce the effect of size differences due to sex, but …

'This Disc Is Not For A Bird Bath, It's For My Tractor': Exploring Gender, Sustainable Agriculture, And Networks In Western Montana, Eva Kathryn Rocke

Graduate Student Theses, Dissertations, & Professional Papers

Women’s presence in agriculture as farmers, consumers, advocates, and activists has become ever more apparent over the last two decades as census data, popular media, and academic literature increasingly reflect their work. Many of the farmers in western Montana practicing sustainable agriculture are women and have built relationships with other women farmers in the region through existing agriculture-focused organizations like Homegrown and the Western Montana Growers’ Cooperative. Even with the strong presence of these organizations, some women farmers feel there is potential for the formalization of a women farmer network in western Montana that would increase the opportunities for socialization …

Restoration As Caring Practice: A Relational Perspective On Ecological Recovery, Daniel Avery Congdon

Graduate Student Theses, Dissertations, & Professional Papers

Ecological restoration is defined by the Society for Ecological Restoration (SER) as “the process of assisting the recovery of an ecosystem that has been degraded, damaged or destroyed” (9). In practice, restoration typically involves the removal of pollution, human-made structures (like dams or roads), invasive species, and other impediments to ecological health. Removing the sources of ecological impairment is coupled with the reintroduction of flora, fauna, and the physical structures that are necessary for healthy ecosystem function. The potential for restoration to dominate nature is a concern of environmental ethicists. In theory, domination might stem from the technology used in …

Understanding Traditions And Practices Of Medicinal Plant Use In Carhuamayo, Junin, Peru, Anastasia Orkwiszewski

Graduate Student Theses, Dissertations, & Professional Papers

Understanding and preserving Traditional Ecological Knowledge and Practices (TEKP) are essential for the continued resilience and cultural diversity of humanity. TEKP faces a multitude of threats from habitat loss, growth of the market economy, globalization, and acculturation. Medicinal plant use in the high Andean town of Carhuamayo, Junín, was studied to assess the vibrancy of that particular branch of TEKP in that area, in what parts of the population it was held, and what factors influence its loss or growth. Gender, age, migrant status, and acculturation levels were not found to be statistically significant in predicting medicinal plant knowledge. Analysis …

The Comet Mine: An Engendered Study Of Victorian Consumption Practices And Material Culture On A Small Mining Landscape, Ryan E. Wendel

Graduate Student Theses, Dissertations, & Professional Papers

The Comet mine is an early 20th-century, largely undocumented mining

community that existed along the periphery of the Coloma Mining District in the Garnet Range of western Montana. During the summer of 2010, archaeological excavations occurred at multiple features at the site.

Spiritual Practices Among Northern Plains Tribal Members As A Protective Factor In The Relationship Between Unexpected Deaths And Traumatic Grief, Ciara D. Hansen

Graduate Student Theses, Dissertations, & Professional Papers

Background: Grief is an important and potentially misunderstood construct in Indian country. Past research has shown that the experience of unexpected deaths has been associated with intense and maladaptive grief responses. Active participation in religion or spirituality has been shown to buffer against the negative effects of bereavement. Given the well-documented premature mortality rates and generally lowered life expectancy in American Indian communities, this study examined the relationships between spirituality, unexpected deaths, and traumatic grief, as measured by the Inventory of Traumatic Grief – Revised (ITG-R). Method: A secondary multiple regression analysis was used to test the hypothesis that …

The Politics Of Melancholy In Alfonso Cuarón’S Y Tu Mamá También, Children Of Men And The Possibility Of Hope, Jessica Anderson

Graduate Student Theses, Dissertations, & Professional Papers

This thesis examines how three films directed by Alfonso Cuarón, Y Tu Mamá También, Children of Men, and The Possibility of Hope, represent the impact of globalization on society and the environment. These films are thematically related, and intended to be considered in connection with one another, as indicated by both interviews with Cuarón, and by critical commentary informing audience reception of these works. Each film uses melancholy as a plot device, and as an ambient presence to elucidate Cuarón’s underlying message that we must re-examine the problematic social, economic and environmental consequences of neo-liberal capitalist models of globalization. Melancholy …
