Search For Selection: Genomic, Transcriptomic, And Phenotypic Investigations Of Spotted Seatrout (Cynoscion Nebulosus), Jingwei Song
Dissertations, Theses, and Masters Projects
Climate change has resulted in both increased mean water temperature and higher frequencies of extreme water temperatures in coastal areas. These new thermal regimes exert strong selective pressure on the thermal physiology of coastal aquatic species. Phenotypic plasticity (the ability of one genotype to display multiple phenotypes) and local adaptation (increased fitness to local environment due to natural selection) dictate both short-term (from hours to days to weeks) and long-term (from years to decades) resilience of a species. To better predict how a species will respond to the negative impacts of climate change, one first needs to know the current …

Dissertations, Theses, and Masters Projects
This study explores how illicit transatlantic trade relations with the Dutch in seventeenth-century Virginia can be identified through the material record. The research was motivated by recent excavations at a seventeenth-century plantation on Virginia’s Eastern Shore. Eyreville, as it is now known, was a hub of transatlantic trade during the formative years of the Virginia colony. The recognizable presence of Dutch trade goods, coupled with the site’s pro-Dutch merchant residents, prompted the investigation into material signatures of illicit trade on the Eastern Shore and the Chesapeake. The identification of these material signatures is based on extensive research into geopolitical histories, …
Mindfulness Moderates The Association Between Internalizing Symptomatology And Emotional Eating, Ti Hsu
Mindfulness Moderates The Association Between Internalizing Symptomatology And Emotional Eating, Ti Hsu
Dissertations, Theses, and Masters Projects
Emotional eating is defined as the tendency to increase food consumption in order to modify negative emotional states. Although it is counter to the more typical response of decreasing food intake in the face of distress, emotional eating is observed in both eating disordered and healthy populations and is associated with overweight and obesity. Theories on emotional eating attribute its cause to inadequate emotion regulation, specifically an inability to draw awareness to and accept distress. Mindfulness, or the ability to pay attention to one's internal and external experiences, is negatively associated with both emotional eating and psychological distress. Only one …

The Role Of Suspended Sediment In Assessing Coastal Wetland Vulnerability, Daniel J. Coleman
The Role Of Suspended Sediment In Assessing Coastal Wetland Vulnerability, Daniel J. Coleman
Dissertations, Theses, and Masters Projects
Coastal wetlands sequester carbon, attenuate waves and storm surge, filter out nutrients and pollutants, and act as nursery habitat for important fisheries. The value of these ecosystems is underscored by their vulnerability to climate change, especially sea level rise. To persist under the threat of rising sea level, coastal wetlands must build elevation vertically. Delivery of sediment to the marsh during tidal flooding is a key component in the ecogeomorphic feedbacks that lead to elevation gain. Despite the importance of suspended sediment to assessing coastal wetland vulnerability, many questions remain unanswered. This dissertation addresses the impact of suspended sediment concentration …

The impact of molecular aggregation on the photophysics of eosin y adsorbed to TiO2 was investigated using diffuse reflectance spectroscopy, steady-state fluorescence and time correlated single photon counting (TCSPC) measurements. Deconvolution of the diffuse reflectance spectra of eosin y on TiO2 revealed the formation of H-aggregates, with the extent of H-aggregation increasing with increasing dye-loading concentration. The resultant bathochromic shift from the monomer diffuse reflectance maximum is due to Charge-transfermediated H-aggregates The fluorescent maximum also shifts with increasing dye loading concentration starting at 537.5 nm at a dye loading concentration of 7.5x10-7 M and shifting to 585 …
Experiments And Theory On Dynamical Hamiltononian Monodromy, Matthew Perry Nerem
Experiments And Theory On Dynamical Hamiltononian Monodromy, Matthew Perry Nerem
Dissertations, Theses, and Masters Projects
In classical mechanics, one of the advanced topics is the study of action and angle variables. These variables are quite abstract, but very powerful tools for describing classical motion. If a system has a full set of conservation laws, and if the motion of the system is bounded, then the motion can be described as flow on a torus. Action variables are functions of the conservation laws that identify the torus on which the motion lies, while angle variables tell the location of the system on that torus. In certain cases, the functional relationship between the conservation laws and the …
