The True Legacy Of Atkins And Roper: The Unreliability Principle, Mentally Ill Defendants, And The Death Penalty’S Unraveling, Scott E. Sundby Dec 2014

The True Legacy Of Atkins And Roper: The Unreliability Principle, Mentally Ill Defendants, And The Death Penalty’S Unraveling, Scott E. Sundby

William & Mary Bill of Rights Journal

In striking down the death penalty for intellectually disabled and juvenile defendants, Atkins v. Virginia and Roper v. Simmons have been understandably heralded as important holdings under the Court’s Eighth Amendment jurisprudence that has found the death penalty “disproportional” for certain types of defendants and crimes. This Article argues, however, that the cases have a far more revolutionary reach than their conventional understanding. In both cases the Court went one step beyond its usual two-step analysis of assessing whether imposing the death penalty violated “evolving standards of decency.” This extra step looked at why even though intellectual disability and youth …

Simulation Based Evaluation Of Multiscale Small Area Health Models, Purbasha Dasgupta Dec 2014

Simulation Based Evaluation Of Multiscale Small Area Health Models, Purbasha Dasgupta

Theses and Dissertations

The effects of scale on the analysis of spatial data, often referred to as the modifiable areal unit problem in spatial studies, is one of the issues often encountered in small area health models. These spatial effects of scale are also seen in the areas of disease mapping where data are usually available in counts. Often there is a need to consider the different scales of aggregation that exist within count data, since inferences based on analyses can vary if we change the definition of the unit of analysis. This thesis provides a framework that describes the distribution of relative …

Modeling Mussel Mortality: Investigating The Importance Of Swash And The Potential Implications Of Changing Wave Environments, Shadow Leigh Gulledge Dec 2014

Modeling Mussel Mortality: Investigating The Importance Of Swash And The Potential Implications Of Changing Wave Environments, Shadow Leigh Gulledge

Theses and Dissertations

Rising sea level and increases in temperature are causing biogeographic shifts in intertidal zones and can also lead to shifts in the local vertical zonation of organisms due to changes in body temperature during aerial exposure during low tide. Swash is an important determinant of aerial body temperatures, and vulnerability of intertidal zones to changes in climate could potentially depend on how much and how often animals are cooled by waves. While wave heights (and thus swash) are generally expected to increase with climate change, anthropogenic physical structures, such as breakwaters and wave energy converters, can decrease wave height and …

An Analysis Of The Cultural Invariance Of A Visual-Motor Integration Measure, Emma Kate C. Wright Dec 2014

An Analysis Of The Cultural Invariance Of A Visual-Motor Integration Measure, Emma Kate C. Wright

Theses and Dissertations

As diverse populations within schools increase, the need for culturally-sensitive assessment is essential; however, test of ability vary in their degree of influence from culture. No test is “culture free,” but the low-linguistic demands on test of visual-motor integration (VMI) make them appropriate for use with diverse populations. Variation in VMI test performance due to cultural factors has negative implications for test interpretation and use with diverse populations because of VMI’s significant association with school readiness, academic achievement, social-emotional functioning, and neuropsychological assessment. The current study explored the cultural invariance of the Bender Motor Gestalt Test, Second Edition (BG-II), a …

Life Satisfaction And Academic Performance In Early Adolescents: Evidence For Reciprocal Relationships, Zi Jia Ng Dec 2014

Life Satisfaction And Academic Performance In Early Adolescents: Evidence For Reciprocal Relationships, Zi Jia Ng

Theses and Dissertations

Student well-being remains a relatively neglected topic despite its intimate link to positive school outcomes. As academic achievement is the yardstick of student success and school accountability, school-based mental health research and practice have focused primarily on the assessment and treatment of learning and behavioral problems. This shortterm longitudinal study sought to establish the role of student subjective well-being in academic achievement. Based on the engine model of well-being (Jayawickreme, Forgeard, & Seligman, 2012), the study focused on life satisfaction as a process variable and academic performance as an outcome variable. Using two waves (five months apart) of data, the …

Relationships Between Prior Experiences, Current Teaching Contexts, And Novice Teachers' Use Of Concrete Representation For Mathematics Instruction, Elizabeth Lee Johnson Dec 2014

Relationships Between Prior Experiences, Current Teaching Contexts, And Novice Teachers' Use Of Concrete Representation For Mathematics Instruction, Elizabeth Lee Johnson

Theses and Dissertations

This case study documents the perceived influences on three novice elementary teachers’ use of concrete representations for teaching mathematics. In order to develop mathematical proficiency, students need access to a variety of representations (i.e. pictures, words, symbols, concrete materials, and real world contexts) to make sense of mathematical ideas. Three sources of data were collected: video-recorded lessons, interviews, and a focus group. Analyses indicated that although concrete representations were accessible to all three teachers, they were least used among the available representations. Verbal expression was most prominent, followed closely by abstract written symbols. Technology, which was not one of the …

Toward The Combinatorial Development Of Hydrophobic-Tagged Antifolate-Directed Degradation Of Human Thymidylate Synthase, Daniel J. Menasco Dec 2014

Toward The Combinatorial Development Of Hydrophobic-Tagged Antifolate-Directed Degradation Of Human Thymidylate Synthase, Daniel J. Menasco

Theses and Dissertations

Direct post-translational control over a protein of interest (POI) can be exploited by manipulating the cells protein quality-control systems responsible for either intracellular turnover through ubiquitination (POI half-life) or repairing and degrading misfolded proteins.1 In an effort to target and degrade a high value POI we selected the enzyme human thymidylate synthase (TS) for post-translational degradation through ligand-directed ubiquitination and hydrophobic tagging. Thymidylate synthase catalyzes the reductive methylation of 2’-deoxyuridine monophosphate (dUMP) to 2’-deoxythymidine monophosphate (dTMP). As the de novo source of dTMP the regulation of intracellular TS is strictly controlled by ubiquitinindependent proteasomal degradation mediated by an internal TS-degron …

Defining And Supporting Organizational Readiness In The Interactive Systems Framework For Dissemination And Implementaion, Jonathan Peter Scaccia Dec 2014

Defining And Supporting Organizational Readiness In The Interactive Systems Framework For Dissemination And Implementaion, Jonathan Peter Scaccia

Theses and Dissertations

Introduction. In the implementation literature, organizational readiness is associated with an increased likelihood of achieving innovation outcomes. Organizational readiness consists of organizational capacity (general and innovation-specific) and organization motivation. Organizations who wish to get results from their innovations have an interest in making sure that certain factors and subcomponents are in place. However, having awareness that certain capacities and factors that influence motivation are linked to improved innovation outcomes does not necessarily help organizations to get “more ready.” There is a need for organizations to know if and how they can effectively put these factors and subcomponents into place. This …

Universal Two-Electron Correlation Operator On Excited States, Bryan Thomas Nichols Dec 2014

Universal Two-Electron Correlation Operator On Excited States, Bryan Thomas Nichols

Theses and Dissertations

Excited states of chemical systems are extremely important in understanding spectra, chemical phenomena, as well as how a particular compound behaves in reactions. Computationally, excited states are normally very expensive to calculate. The difficulty in calculating these states with wavefunction based methods can be mainly attributed to the calculation of large multi-determinant wavefunctions. One reason to use a complicated multi-determinant wavefunction is to include some of the effects of correlation energy. The quantity of correlation energy can most simply be defined as the reduction in energy caused by any two or more electrons trying to avoid each other. The most …

Experimental And Theoretical Studies Of Native And Engineered Vascular Tissue Mechanics, Boran Zhou Dec 2014

Experimental And Theoretical Studies Of Native And Engineered Vascular Tissue Mechanics, Boran Zhou

Theses and Dissertations

Background: Implantation of vascular grafts provides a means to restore blood flow in compromised regions of the circulatory system, and thus is used to treat a wide range of cardiovascular diseases. Despite significant advancements in autologous grafting strategies as well as the engineering of synthetic alternatives, mechanical, structural, and compositional incongruities between the graft and the host artery remain as contributing factors to graft failure. The typical failure modality manifests as proximal anastomotic intimal hyperplasia, which places restrictions on the host vessel size currently treated with grafting strategies (> 5 mm internal diameter). In order to improve long-term clinical outcomes, …

Automated Scratchpad Mapping And Allocation For Embedded Processors, Yang Gao Dec 2014

Automated Scratchpad Mapping And Allocation For Embedded Processors, Yang Gao

Theses and Dissertations

Embedded system-on-chip processors such as the Texas Instruments C66 DSP and the IBM Cell provide the programmer with a software controlled on-chip memory to supplement a traditional but simple two-level cache. By decomposing data sets and their corresponding workload into small subsets that fit within this on-chip memory, the processor can potentially achieve equivalent or better performance, power efficiency, and area efficiency than with its sophisticated cache. However, program controlled on chip memory requires a shift in the responsibility for management and allocation from the hardware to the programmer. Specifically, this requires the explicit mapping of program arrays to specific …

Applications Of Nonlinear Optimization, Yao Xie Dec 2014

Applications Of Nonlinear Optimization, Yao Xie

Arts & Sciences Graduate Student Theses and Dissertations

We apply an interior point algorithm to two nonlinear optimization problems and achieve improved results. We also devise an approximate convex functional alternative for use in one of the problems and estimate its accuracy. The first problem is maximum variance unfolding in machine learning. The traditional method to solve this problem is to convert it to a semi-definite optimization problem by defining a kernel matrix. We obtain better unfolding and higher speeds with the interior point algorithm on the original non-convex problem for data with less than 10,000 points. The second problem is a multi-objective dose optimization for intensity modulated …

Synthesis And Characterization Of Pbs Quantum Sheets Through Lamellar Assembly, And Updates To The Cdse Quantum Wire Synthesis, Paul James Morrison

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation reports the novel synthesis of PbS quantum plates (QPs) via a reaction executed at low temperatures. The PbS QPs are grown in a template-assisted mechanism, with the first excitonic peak observed in the visible region of light at ~620 nm (2.0 eV), at an energy radically different than the band gap of bulk PbS (~3000 nm, 0.42eV). The large energy shift is due to the extremely thin dimension of these nanoplates, which is determined to be ~1 nm in thickness. Thickness measurements are made in a powder X-ray diffractometer (XRD) at low angles (between 2-15º 2θ). These measurements …
