New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a given thesis/dissertation in DRUM.

Item More Than the 'Physical Remains of Yesterday's Industry:' A Case Study of the Clayton Cotton Mill(2021) McCoy, Abigail; Palus, Matthew M.; Anthropology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The historic Clayton Cotton Mill located in Clayton, North Carolina, operated from the early- to mid-twentieth century. This research investigates the quality and quantity of data that is recovered from twentieth century industrial sites when investigators utilize the methodologies and research interests of labor archaeology. It also examines how labor archaeology informs questions relating to race, paternalism, and child labor, and how labor archaeology’s methodologies highlight the potential public value of the resource.The initial archaeological investigations conducted at this mill were focused on traditional industrial archaeology research questions and concluded that the resource was not eligible for listing on the NRHP without considering research avenues associated with labor archaeology. The goal of this project is to evaluate this resource through the lens of labor archaeology, identifying valuable information that adds to a more complete understanding of the resource and would have been lost if the original recommendation was accepted.Item RE-OS AND OXYGEN SYSTEMATICS OF VARIABLY ALTERED ULTRAMAFIC ROCKS, NORTH CAROLINA(2020) Centorbi, Tracey; Walker, Richard J.; Geology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This study focuses on the origin and modification of six ultramafic bodies located in the Blue Ridge Province of North Carolina. The bodies consist mainly of harzburgites and dunites with associated chromites. Some of the bodies are associated spatially and genetically with mafic lithologies while others are fault bounded. All the bodies in the study are characterized by variations in their initial Os isotopic compositions, assuming a formation age of 490 Ma (187Os/188Osinitial 0.1114 to 0.1360). Most of the initial 187Os/188Os ratios are chondritic to subchondritic and can be explained by Re depletion during a partial melting event prior to ophiolite formation. By contrast, some initial 187Os/188Os ratios, particularly for those bodies in the Tallulah Falls formation, are suprachondritic suggesting the addition of radiogenic Os during a melt percolation or melt/rock reaction event, most likely during the event that led to the formation of the bodies. Oxygen isotopic δ18O values of the bodies range from +4.85 to +7.60 which overlap with and extend above mantle estimates. The cause of the higher values remains unresolved, but serpentinization and contamination by large amounts of crustal material can be excluded. It is concluded that the six bodies in this study have a common history as the residues of mantle partial melting, with chemical compositions and isotopic systematics similar to Phanerozoic ophiolite peridotites associated with the same collisional event, as well as modern abyssal peridotites. Nevertheless, Os isotopic characteristics indicate different processes acted within the bodies despite their relatively close spatial association.Item ‘DEVOTED TO THE INTERESTS OF HIS RACE’: BLACK OFFICEHOLDERS AND THE POLITICAL CULTURE OF FREEDOM IN WILMINGTON, NORTH CAROLINA, 1865-1877(2016) Jackson, Thanayi Michelle; Rowland, Leslie S.; History; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This dissertation examines black officeholding in Wilmington, North Carolina, from emancipation in 1865 through 1876, when Democrats gained control of the state government and brought Reconstruction to an end. It considers the struggle for black office holding in the city, the black men who held office, the dynamic political culture of which they were a part, and their significance in the day-to-day lives of their constituents. Once they were enfranchised, black Wilmingtonians, who constituted a majority of the city’s population, used their voting leverage to negotiate the election of black men to public office. They did so by using Republican factionalism or what the dissertation argues was an alternative partisanship. Ultimately, it was not factional divisions, but voter suppression, gerrymandering, and constitutional revisions that made local government appointive rather than elective, Democrats at the state level chipped away at the political gains black Wilmingtonians had made.
