The recent civil war in Sierra Leone (1991-2002) saw massive migrations amongst the civilian population and widespread damage to villages and towns. This study combines elements of military and cultural geography to ask the questions of how the events of the war changed the cultural landscape and how the cultural landscape influenced the course of the war. Fieldwork for this study was conducted during the summer of 2005 in the Eastern Province and included numerous semi-structured interviews regarding the landscape histories of villages, towns, and various temporary camps. These findings revealed that a clear relationship existed between the civil war and the cultural landscape. On the one hand, the war caused dramatic changes in the morphology of the cultural landscape, creating three distinct landscapes (pre-war, wartime, and post-war), while on the other hand the cultural landscape went far to structure the character of the war. In order to understand how the cultural landscape structured the war one must first consider how the landscape was perceived by each major faction (Revolutionary United Front, Sierra Leone Army, and Civil Defense Forces) as presenting a unique set of risks and opportunities. This perception was based in their strategic intentions and capabilities. Intentions can be understood as military objectives (derived from political goals), while capabilities can be understood as factors which constrain and enable action. Since each faction had different military objectives and capabilities they each perceived the landscape in a unique manner and this perception influenced their military operations. It is recommended that cultural geographers begin to study the impacts of war on the landscape and that military geographers expand their focus on the physical landscape by taking into account the role of the cultural landscape and environmental perception.

Abstract Residents of communities that are at the edge of the rural-urban divide are likely to have many senses of place reflective of the changes occurring around them. As the place where they have resided in and identify with becomes transformed by changes in land use and social composition, these residents may be forced to either adapt or leave. Often overlooked, these individuals may feel as if the place where they have long resided is no longer their home. As the familiar routes, stores, and neighborhoods give way to new highways, big name stores, and exclusive subdivisions, their understanding of its sense of place becomes challenged. This thesis seeks to understand changing senses of place among residents in Lutz, an unincorporated community at the edge of the city of Tampa in Florida. Using a humanistic geography approach which focuses on individual perceptions, nine semi-structured interviews were conducted on questions related to community boundaries, everyday experiences of demographic and land use transformations, and possible futures of the community. Further background on the community was collected by traveling through it and analyzing media accounts which provided both historical and contemporary perspectives on its cultural landscapes. One of the main findings of this thesis is that the unincorporated nature of this community adds a unique dimension to discussions of its socio-spatial transformations since the role of boundaries in sense of place becomes complicated here. Thus, in contrast to firm lines drawn by cartographers or postal agencies, cultural boundaries have a high degree of subjectivity and are often at odds with official demarcations. Overall, this thesis highlights the value of focusing on residents of unincorporated communities in order to build more complex notions of place-based identities.

Commercial strips are ubiquitous elements of the American landscape. They offer important opportunities for inquiry into the ways in which cities are adapted, preserved, and redeveloped over time. This research examines the dynamics of reinvestment along central city commercial strips in Austin, Texas. Research was aimed at understanding the relationship between reinvestment in existing commercial buildings and larger processes of redevelopment and change along commercial strips undergoing transition. Case study commercial strips were selected that had been established in the early to mid-twentieth century and that had experienced decline and subsequent reinvestment. Historic patterns of land use, transportation, and economic trends are described and related to the relatively recent growth of concentrations of local businesses and reinvestment activity along case study commercial strips. “Core samples” of preservation and adaptive reuse were examined using spatial data, building surveys, historical data, and interviews with associated actors. Additional interviews were conducted with actors who have initiated, influenced, and regulated reinvestment, including business and property owners, developers, neighborhood activists, a media correspondent, city officials, among others. This research details the private, public, and community-based actors who shape the character of reinvestment; the influx of new businesses and retention of iconic businesses; and conflicts and negotiations at the edges of commercial and residential districts and between public and private sectors. The dissertation relates observations along Austin’s commercial strips to four themes identified in the literature and their associated views of improvement: 1. commercial strips as “wicked problems” of land use and transportation; 2. commercial strips as cultural landscapes and roadside heritage; 3. commercial strips as concentrations of commercial properties with opportunities for sustainability and retrofitting of commercial properties; and 4. commercial strips as contested arenas of gentrification. This research highlights the importance of understanding the durability of existing land development patterns and of incorporating an understanding of the continued and adaptive use of buildings and urban fabric in land use planning. It presents emerging opportunities for preservation practice beyond standard practices of survey and landmarking. It illustrates the many ways in which actors have agency, or “choreograph” change individually and collectively, in responding to opportunities and challenges presented in the context of social and economic change. / text

The Bureau of Reclamation (BOR) is interested in understanding the human and environmental consequences of past Glen Canyon Dam water release policies and using these data to inform future water release and land management policies. One step in this direction is to understand how American Indian people have used the Colorado River and adjoining lands in Glen Canyon and Grand Canyon. The BOR, through its Glen Canyon Environmental Studies (GCES) office, has provided funds for various American Indian groups to identify places and things of cultural significance in the 300 mile long river and canyon ecosystem that has come to be called the Colorado River Corridor. This study is the second to report on the cultural resources of the Southern Paiute people found in this riverine ecosystem. The rock art study funded by the BOR and managed by the Glen Canyon Environmental Studies (GCES) office is the basis of this report. This study is unique in the history of rock art studies and is unusual when compared with other American Indian cultural resource assessments. There are five unique features of this study. First, all funds for conducting the research were contracted to the Southern Paiute Consortium. Second, the Southern Paiute people decided during the previous studies that their next study would be about rock art. Third, the GCES /BOR permitted research to be conducted in terms of Paiute perceptions of the study area rather than specifically in terms of the scientifically established study area for the project. Thus, it was possible to conduct the Kanab Creek side canyon study. Fourth, all interviews were guided by a ten -page survey instrument, so Southern Paiute responses could be systematically compared. Fifth, both all-male and all- female research trips were conducted, thus producing the first gender - specific interviews of rock art sites. The resulting study is both interdisciplinary and multivocal.

Beginning in the second half of the twentieth century, three American astronomical observatories in Arizona and Hawai'i were transformed from scientific research facilities into mountains of controversy. This dissertation examines the histories of conflict between Native, environmentalist, and astronomy communities over telescope construction at Kitt Peak, Mauna Kea, and Mt. Graham from the mid-1970s to the present. I situate each history of conflict within shifting social, cultural, political, and environmental tensions by drawing upon narrative as a category of analysis. Astronomers, environmentalist groups, and the Native communities of the Tohono O'odham Nation, the San Carlos Apaches, and Native Hawaiians deployed competing cultural constructions of the mountains--as an ideal observing site, a "pristine" ecosystem, or a spiritual temple--and these narratives played a pivotal role in the making of contested landscapes in postwar American astronomy. / History of Science

In this thesis, I discuss engineering colloidal particles to have specific, isotropic interactions and studying their cluster geometries in equilibrium. I discuss light scattering experiments showing that a highly specific protein, Dscam, is unstable against thermal aggregation. This result lead me to use DNA instead to control interparticle specificity. I coated 1-micron diameter polystyrene particles uniformly with DNA. I used fluorescence microscopy with oxygen-scavenging enzymes to observe these particles self-assembling in clusters. These experiments show that a packing of 6 spheres that is rarely seen in a single-component system is observed very often in an optimized 3-species system. Then I show experiments using the same 3 species but 9 total particles, finding that the equilibrium yields of the most likely cluster relative to other stable clusters are lower than at 6 particles. I conclude from these experiments that optimizing the assembly of an otherwise unlikely configuration may require nearly as many species as particles. Finally, I investigate the scalability of self-assembly of particles with isotropic and specific interactions theoretically. I use both exact and approximate partition functions to show that spheres with specific interactions can have energy landscapes with thermodynamically large numbers of strictly local minima relative to the number of their ground states. Compared to single-component systems, these systems of many different species may spend much more time in kinetic traps and never reach their ground states. Finally, I discuss briefly some directions for further study, including questions of how the results in this thesis may be related to protein folding and complex formation. / Engineering and Applied Sciences

Based on ethnographic research conducted in the Exumas Cays, Bahamas, this thesis investigates how traditional ecological knowledge (TEK) and conservation ethics are situated in place and integrated into cultural landscapes. This is illustrated using satellite imagery and ethnographic data to describe the TEK associated with kitchen gardens, plant-collecting areas, fishing grounds, farm fields and pastures within the traditional use areas of one Exumian settlement known as The Hermitage. By situating TEK in cultural landscapes, this thesis provides a more holistic representation of the interconnectedness between community, knowledge, practice, belief, place, and landscape. This thesis also includes discussions on the theoretical importance of linking TEK with place and landscape; the formation and role of conservation ethics in preserving places or resources in a local environment; and a description of an emerging theory in cultural ecology called environmental multiplicity, which argues for the resiliency of traditional social-ecological systems as a result of creating multiple subsistence strategies and webs of interdependent social relationships to guard against social and natural perturbations.
