Children were especially vulnerable, perishing with disheartening frequency throughout the century. Yet despite the high rates of child mortality, Tidewater culture underwent a revolution in regard to the eighteenth-century family. Children became the emotional focus of the family, becoming cherished for their youthful capering and playful nature. However, child death was no less common. The way in which parents coped with the death of a child changed throughout the century, reflecting the emotionalized understanding of children and childhood. The rituals surrounding the death of a child—from preparations for burial, the funeral, and lasting commemorations—evolved over the course of the eighteenth century, reflecting the new place of the child within the eighteenth-century family and the emotional trauma felt by the family after the death of a child. / Master of Arts Virginia society Tidewater infant mortality Eighteenth century child mortality family culture
12	Trace Metals and Stable Isotopes as Tracers of Life History and Trophic Connections in Estuarine-Dependent Fish from Tampa Bay, Florida Boehme-Terrana, Linae Marie 15 November 2007 (has links) Florida's estuaries support a wide range of species yet little is known about tracemetal cycling among members of this important ecosystem. To examine the flow of trace metals through the Tampa Bay estuary, four fish species representing different trophic levels were analyzed for copper (Cu), zinc (Zn) and stable isotopes of carbon (C) and nitrogen (N). Species selected were the striped mullet (Mugil cephalus), tidewater mojarra (Eucinostomus harengulus), bay anchovy (Anchoa mitchilli), and sand seatrout (Cynoscion arenarius). Juvenile fish were collected from the Alafia, Hillsborough, Palm, and Little Manatee Rivers. Adults were collected from Tampa Bay. Combinations of trace metal and stable isotope analyses were used to evaluate geographic variability in trace metal concentrations among locations in Tampa Bay and to shed light on trophic pathways that lead to trace metal accumulation. In juvenile mullet, significant trends were found between Zn concentrations, stable isotope ratios, and standard length. Animals of the smallest size classes carry greater concentrations of zinc in their tissues and have distinct stable isotope ratios that reflect their recent life history as offshore planktivorous larvae. Interestingly, the ratio of Zn:Cu concentrations was highly conserved. While species-specific differences were observed, relatively small Zn:Cu variations suggest a possible bioregulatory mechanism that maintains an optimal Zn:Cu ratio even in the presence of elevated absolute metal concentrations. Stable isotope ratios proved to be an effective tracer of ontogenetic changes in fish diet and habitat. Carbon and nitrogen stable isotope analyses revealed that trophic relations between species are established very early in an organism's life history. The bay anchovy, a major prey item of the sand seatrout, has δ15N values very similar to this predator. Although trophic linkages between trace metals and stable isotopes proved difficult to interpret, the relation between zinc concentrations and δ¹³C values suggested that trace metal concentrations are highest in animals that utilize food webs based on terrestrial carbon.

14	The Unquantified Mass Loss and Changes of Northern Hemisphere Marine-Terminating Glaciers Kochtitzky, William 24 August 2022 (has links) Most of the glacier-caused sea level rise to date has been sourced from melt and icebergs from marine-terminating glaciers. Marine-terminating glaciers drain nearly all the Greenland and Antarctic ice sheets and many polar ice caps, ice fields, and mountain glaciers. However, we previously did not know how much solid mass, or frontal ablation, was lost by these glaciers, a key component of glacier mass balance. This thesis quantifies the area change and mass loss of marine-terminating glaciers in the Northern Hemisphere from 2000 to 2020 by quantifying glacier retreat, advance, and frontal ablation. In total, the 1704 marine-terminating glaciers in the Northern Hemisphere lost an average of 389.7 ± 1.6 km² a⁻¹ of their terminus from 2000 to 2020, for a total of 7527 ± 31 km², with 123 glaciers ceasing to be marine-terminating over this period. Overall, 85.3% of glaciers retreated, 2.5% advanced, and the remaining 12.3% did not change outside of uncertainty limits. Frontal ablation of marine-terminating glaciers, not including the Greenland Ice Sheet, contributed an average of 44.47 ± 6.23 Gt a⁻¹ of ice to the ocean from 2000 to 2010, and 51.98 ± 4.62 Gt a⁻¹ from 2010 to 2020. Ice discharge from 2000 to 2020 was equivalent to 2.10 ± 0.22 mm of sea-level rise and comprised approximately 79% of frontal ablation, with the remainder from terminus retreat. In Greenland, frontal ablation totaled 522.00 ± 17.38 Gt a⁻¹ for 2000-2010 and 559.05 ± 12.59 Gt a⁻¹ for 2010-2020. Ice discharge comprised ~90% of frontal ablation during both periods, while volume loss due to terminus retreat comprised the remainder. In total, Greenland accounted for 90% of northern hemisphere frontal ablation from 2000 to 2020. When combined with climatic-basal mass balance estimates this allows for the first estimate of complete Northern Hemisphere glacier mass budgets, which shows that Arctic Russia, Greenland, and Svalbard have positive climatic-basal balances. For the first time, this thesis provides complete frontal ablation estimates for the entire Northern Hemisphere of 522.0 ± 17.4 Gt a⁻¹ for 2000-2010 and 559.1 ± 12.6 Gt a⁻¹ for 2010-2020. glacier Alaska Canada Greenland Svalbard Iceland Russia climate change remote sensing icebergs ocean frontal ablation satellites calving Landsat Sentinel GIS tidewater glacier
15	Legislating the Danville Connection, 1847-1862: Railroads and Regionalism versus Nationalism in the Confederate States of America Stanley, Philip 01 January 2014 (has links) This thesis examines the effect regionalism had upon North Carolina and Virginia during the 1847-1862 legislative battles over the Danville, Virginia, to Greensboro, North Carolina, railroad connection. The first chapter examines the rivalry between eastern and western North Carolina for internal improvement legislation, namely westerners’ wish to connect with Virginia and easterners’ desire to remain economically relevant. The second chapter investigates the Tidewater region of Virginia and its battle against the Southside to create a rail connection with North Carolina. The third chapter examines the legislation for the Danville Connection during the American Civil War in the Virginia, North Carolina, and Confederate legislatures. Through an examination of voting patterns and public opinion, this thesis finds that, despite Confederate President Jefferson Davis’s designation of the Danville connection as a military necessity, regionalism overcame Confederate nationalism during this instance.

17	Off-Host Biology and Ecology of Immature Gulf Coast Ticks (Amblyomma Maculatum Koch) in Mississippi Portugal, Jose Santos 06 May 2017 (has links) Little is understood about off-host behavior and ecology of immature Amblyomma maculatum Koch (Gulf Coast tick). A more complete understanding of this tick is essential to protect human and animal health. My research focused on seasonality and distribution of immatures in Mississippi, potential suitability of some insect and human hosts to larvae, and aspects of nymphal questing behavior. A single larva was collected (third off-host collection reported) when sampling A. maculatum habitat using a novel device. Collection of this larva in November expands the stage’s known seasonality and confirmed a prediction concerning seasonality of larval A. maculatum. Low frequency of immatures (8.3%) confirmed that they’re incredibly difficult to collect off-host. Nymphal collections peaked in March, and known seasonality was extended for both nymphs and adults. I examined known records, elucidating seasonality and distribution of A. maculatum in Mississippi. Either multiple generations per year or diapause are responsible for observed bi-modal distribution of immature collections. Additionally, I compiled the most extensive host record of immature A. maculatum in Mississippi and investigated seasonality patterns using USDA plant hardiness zones. I compiled the most complete record of ticks found on arthropods. Amblyomma americanum and A. maculatum were both confirmed to crawl onto arthropods, giving support to occasional, unintentional dispersal by phoresy. There was no conclusive evidence that larval A. maculatum feed on arthropods, however data supported feeding by larval A. americanum. These results have interesting implications regarding evolution of pathogens/endosymbionts. I provided the first evidence that larval A. maculatum can attach to humans. Rickettsia parkeri, a human pathogen transmitted by this species has recently been shown to be capable of transovarial transmission. Therefore, larval A. maculatum may provide another avenue of transmission. I have demonstrated that A. maculatum are difficult to collect off-host in part because they prefer to quest low to the ground. In choice studies, 5-cm-tall stems were most likely to be occupied by nymphs released into an array of stems. Low vapor pressure deficit encouraged questing, while higher VPD and warmer temperature increased questing height. These results may have implications in understanding host-seeking behavior in other tick species as well. water vapor relative humidity fall armyworm house cricket European honey bee Spodoptera frugiperda Acheta domesticus Apis mellifera parumapertus Tidewater spotted fever Rickettsia parkeri rickettsiosis Heartwater Ehrlichia ruminantium Hepatozoon americanum scapularis Maculatum group Neotropical Water vapor Ixodes Dermacentor critical equilibrium humidity critical equilibrium activity Nearctic Boophilus Rhipicephalus southeast National Tick Collection hemolymph americanum nitens variabilis Andropogon virginicus broomsedge tickarium photophase fixed action pattern fixed behavior Candidatus Rickettsia andeanae
18	From Tidewater to Tennessee: The Structuring Influences of Virginia Schemata in the Settlement of East Tennessee Nakoff, Slade 01 May 2024 (has links) (PDF) For over two hundred years, historians have debated the historical importance of early Tennessee migrants in shaping the state’s history. These discussions center around North Carolina's impact compared to Virginia's. By shifting discourse to the retention of migrant mentalities, the overwhelming influence of Virginia emerges through the continuity of privilege and commodification schemata. This study employs an interdisciplinary methodological approach combining schema theory, memory studies, and material culture analysis to outline the retention of mentalities from Tidewater, Virginia, to East Tennessee during the early settlement period. By utilizing the case study of John Carter of Watauga (1728-1781), the research illustrates how Virginian origins shaped settlers’ perceptions of privilege through inheritance, ordered society, and models of success, as well as commodification through ownership, resource extraction, and speculation. Findings reveal that Virginian mental frameworks were foundational paradigms, guiding settlers’ actions and perpetuating hierarchical structures within Tennessee society. Despite the opportunity for deviation that migration and community establishment provided, elite settlers chose to assimilate and reestablish the dominant position of Virginian schemata within their new environment. The persistence of Virginian schemata in Tennessee informs broader questions of identity formation, migrant nostalgia, and the enduring legacy of colonial mentalities in shaping American history.
