Late Pleistocene Climate, Vegetation, And Fire History From A Southern Appalachian Bog, Whiteoak Bottoms, Nantahala National Forest, North Carolina, U.S.A., Mathew Stephen Boehm
Late Pleistocene Climate, Vegetation, And Fire History From A Southern Appalachian Bog, Whiteoak Bottoms, Nantahala National Forest, North Carolina, U.S.A., Mathew Stephen Boehm
Masters Theses
I examined loss-on-ignition, pollen, and charcoal evidence of climate, vegetation, and fire history at Whiteoak Bottoms (35º04’44”N, 83º31’50”W; 1032 m elevation), a peat-forming wetland located along the Nantahala River in western North Carolina. Previous research by J. McDonald and D. Leigh revealed that this wetland formed in a paleochannel of the Nantahala River between 15,000 and 14,000 cal yr BP. I obtained additional AMS radiocarbon dates, carried out high-resolution loss-on-ignition analysis, and examined pollen and microscopic charcoal assemblages in a 157-cm sediment core from the previous study. Radiocarbon dates and stratigraphic analyses indicate that much of the Holocene is missing …
Contextualizing The Tipton-Haynes State Historic Site (40wg59): Understanding Landscape Change At An Upland South Farmstead., Daniel Whitaker Howard Brock
Contextualizing The Tipton-Haynes State Historic Site (40wg59): Understanding Landscape Change At An Upland South Farmstead., Daniel Whitaker Howard Brock
Masters Theses
This thesis focuses on a contextual archaeological approach to investigate the historic landscape of the Tipton-Haynes State Historic Site. Tipton-Haynes is a late eighteenth- through twentieth-century upland south farmstead located in Johnson City, TN. Home to two prominent Tennessee families and occupied until acquired by the state in the 1960s, the site has experienced many alterations to the landscape over time. The analysis presented views the landscape as material culture investigated through a multidisciplinary approach including historic research, architectural survey, geophysical survey, dendrochronology, and archaeology. To make sense of the complex nature of the Tipton-Haynes site, multiple methods were used …
Online Social Network Friends And Spatio-Temporal Proximity Of Their Geotagged Photos – A Case Study Of Flickr Data, Sumang Liu
Masters Theses
This empirical study aims to analyze relationships between online social network (OSN) friends and spatio-temporal proximity of their geotagged photos, using Flickr data as a case study. First, this study analyzes whether Flickr friends tend to post geotagged photos that are closer to each other compared to Flickr non-friends in space and time. Second, this study investigates whether the number of geotagged photos posted by users is related to the distance and time difference between their geotagged photos. Third, this study examines the spatial distributions of geotagged photos of Flickr friends within specific distance intervals to further understand the geographic …
Public Land In A Changing Climate: Planning For An Uncertain Future, Kathleen Marie Hauser
Public Land In A Changing Climate: Planning For An Uncertain Future, Kathleen Marie Hauser
Masters Theses
This thesis investigates the ways in which institutions and actors consider climate change, and how the inclusion of diverse perspectives and challenges in the planning process shapes climate change governance. In particular, I asked how the participants, place-specific contexts, and decision-making processes affect environmental decision-making in Alaska’s National Parks. I discuss the literature on geographical perspectives on climate change, environmental and climate change governance, how uncertainty and risk affect decision-making in the context of climate change, and the history of land use management in the United States. This project incorporates qualitative methods to research the Climate Change Scenario Planning project …
Response Of Inland Lakes To Climate Change Across The Tibetan Plateau Investigated Using Landsat And Icesat Data, Zewen Liu
Masters Theses
The Tibetan Plateau experienced tremendous climate change during the past four decades. Due to the large size, widely distribution of cryosphere, and diverse landforms, different parts of the plateau may experience different climate and cryosphere changing patterns. The changes of inland lakes within the plateau are important indicators of climate change as these lakes are fed by precipitation, permafrost degradation, and glacier melting that are all sensitive to climate change. To examine the spatial and temporal differences of lake variations across the Tibetan Plateau, Landsat images and ICESat/GLAS altimetry data were used to extract the changes in surface areas of …
Justice, Truth, And Community Organizing In Boston, Ma, Melanie Ann Barron
Justice, Truth, And Community Organizing In Boston, Ma, Melanie Ann Barron
Masters Theses
In 2010, community organizers in Boston, MA began to lay the groundwork for a truth and reconciliation process about the long-term impacts of the violence and racism surrounding the desegregation/busing crisis in the 1970s. Organizers believe that the busing crisis still presents impediments to the ability of communities of color in Boston to live well and participate in public life. I contextualize their efforts first as a response to the failures of the liberal democratic reforms that marked the civil rights movement. Rather than truly reforming the structures that permit the existence of racialized inequalities, I argue that the liberal …
Spatial Discrepancies Between Nhdplus And Lidar-Derived Stream Networks, Nicole Marie Samu
Spatial Discrepancies Between Nhdplus And Lidar-Derived Stream Networks, Nicole Marie Samu
Masters Theses
Many organizations demand that current water resource issues necessitate improved stream network mapping for more accurate and reliable watershed analysis and modeling results, which can ultimately enable better management and policy decisions. Stream network data from the National Hydrography Dataset Plus (NHDPlus) and derived from Light Detection and Ranging (LIDAR) are each widely accepted to be of superior quality compared to many other conventional datasets. Each dataset indicates potential to improve a wide range of water resource applications; NHDPlus for its high spatial accuracy and functionality, and LIDAR-derived networks for their high resolutions. NHDPlus is publicly available and widely used; …
Redefining Memorial Landscapes: The Stolpersteine Project In Berlin, Matthew Russell Cook
Redefining Memorial Landscapes: The Stolpersteine Project In Berlin, Matthew Russell Cook
Masters Theses
Geographers have long been interested in the ways that states and individuals use cultural landscapes to shape the meaning and understanding of the past. In this thesis, I argue that individuals and the state embed different interpretations of the Holocaust past in the German landscape. In particular, I focus on the German artist Gunter Demnig and his Stolpersteine (stumbling stones) Project as a case study of memorial projects created by an individual. The Stolpersteine are small memorial stones for a single Holocaust victim. The stones are installed in front of homes and businesses that were the last known location of …
Reconstruction Of Fire History In The National Key Deer Refuge, Monroe County, Florida, U.S.A.: The Palmetto Pond Macroscopic Charcoal Record, Desiree Lynn Kocis
Reconstruction Of Fire History In The National Key Deer Refuge, Monroe County, Florida, U.S.A.: The Palmetto Pond Macroscopic Charcoal Record, Desiree Lynn Kocis
Masters Theses
The pine rocklands in the Lower Florida Keys are considered endangered because of rises in sea level, urbanization, and human impacts on the natural fire regime. Macroscopic charcoal in a sediment core recovered from Palmetto Pond (24°41’45.15”N, 81°19’43.84”W) in 2010 was examined in contiguous 1-cm intervals to reconstruct Late Holocene fire history. Palmetto Pond is a shallow freshwater solution hole located within the pine rocklands of No Name Key in Monroe County, Florida. Radiocarbon dating of plant material at 247 cm depth in the Palmetto Pond profile indicates the sediment record extends back to ca. 4500 cal yr BP. Charcoal …
Examining Impacts On Water Demand Resulting From Population And Employment Growth Using A Regional Adjustment Model, Steven Blake Thomas
Examining Impacts On Water Demand Resulting From Population And Employment Growth Using A Regional Adjustment Model, Steven Blake Thomas
Masters Theses
This thesis examines the currently available water use data and its limitation for use in scientific research. The first chapter offers a description of the current nationwide water data including descriptions of collection methods and trends found within the data. The varying collection methods used result in inconsistencies within the datasets and between the years. These inconsistencies have resulted in the data being used more as a point of reference than in nationwide empirical analysis of water use. There has been a calling for systematic improvements to the data, which could contribute to greater empirical analysis taking place at the …
