The Effect of Standardised Learning Diaries on Self-Regulated Learning, Calibration Accuracy and Academic Achievement

Avanelle Joseph-Edwards
The online learning environment is a dynamic yet complex learning modality. Students are physically separated from their peers, they grapple with feelings of isolation, and they may be unable to self-regulate their learning. Studies have shown that self-regulation is related to academic achievement and student metacognitive monitoring in online settings. The present study investigated the effects of a standardized diaries on students’ self-regulatory behaviors, calibration accuracy and academic achievement within an online learning environment. Using...

Crime and Panic: Contextual Factors in Violent and Sex Offender Sentencing

Jessica Huffman
Although crime rates have been decreasing nationwide, the public is still very concerned with crime as a social problem and generally supportive of criminal justice penalties for wrongdoing. The mass of punitive laws have been especially harsh on those convicted of sexual offenses, even as these offenders comprise a small part of the entire crime picture. The passage of mandatory minimum sentences and risk management laws for sex offenders suggest a moral panic over sexual...

On the Thermal Stresses Due to a Uniform Heat Flow Past a Circular Hole With a Radial Edge Crack

George F. Edmonds
The problem solved in this dissertation is that of finding the stresses in an isotropic, linear, thermoelastic solid when a uniform heat flow is disturbed by the presence of an insulated circular hole with a radial edge crack. By superimposing a Mellin transform solution of the equations of thermoelasticity on a Michell series solution the author reduces the problem to a pair of singular integral equations which are then solved numerically. The stress intensity factors...

The Geochemistry of Selenium and Sulfur in a Coastal Salt Marsh

David Jay Velinsky
Investigation of the various chemical forms of selenium and sulfur in sediments and pore waters can provide information about various oxidation/reduction processes. Five cores were obtained from the Great Marsh, from April 1985 to June 1986. Sampling times coincided with the seasonal redox cycle known to occur within the marsh system. Sediments were analyzed for various selenium and sulfur phases. Iron monosulfides and elemental sulfur both display large seasonal changes in concentration and distribution with...

Methodology for Analyzing and Characterizing Error Generation in Presence of Autocorrelated Demands in Stochastic Inventory Models

Rafael Diaz
Most techniques that describe and solve stochastic inventory problems rely upon the assumption of identically and independently distributed (IID) demands. Stochastic inventory formulations that fail to capture serially-correlated components in the demand lead to serious errors. This dissertation provides a robust method that approximates solutions to the stochastic inventory problem where the control review system is continuous, the demand contains autocorrelated components, and the lost sales case is considered. A simulation optimization technique based on...

Transverse Variability of the Flow and Density in Inlets of Southern Chile

Mario Arturo Cáceres Muñoz
Measurements of velocity and density profiles were made to describe the flow transverse structure in three inlets of southern Chile. The inlets show marked differences in their transverse dynamics in response to external forcing. In Aysen Fjord (45.2°S) the mean flow showed a three layer structure that was consistent with up-fjord wind-induced exchange, while in Chacao Channel (41.8°S), the mean flow exhibited predominantly a lateral structure that featured sharp velocity shears. In both cases, a...

Holocene Geology and Migration of a Low-Profile Barrier Island System, Metompkin Island, Virginia

Mark R. Byrnes
Analysis of historical shoreline position, cross-island profile change, and stratigraphic data provided a shoreline response model for low-profile barrier island systems. Historical shoreline data illustrates continuous, shore-parallel retreat between 1852 and 1957, at which time the island narrowed to a width of approximately 200 m. Between 1957 and 1981, ephemeral inlet breaching along southern Metompkin Island disrupted longshore sediment transport, increased the rate of shoreline recession, and resulted in differential rates of retreat associated with...
