The primary purpose of this study was to determine whether or not two different phonological awareness techniques utilizing rhyme and alliteration were useful in the acquisition of phonological awareness in at - risk children attending a Head Start …

Can Christians Be Bhaktas? A Sanskritic View From Central India, C. 1850, Richard Fox Young

Journal of Hindu-Christian Studies

My essay focuses on an undeservedly obscure individual, Somanath Vyas, whose name hardly registers among South Asia scholars. Recently, however, Somanath's writings have elicited interest among Sanskritists in Central India where he lived. Of these, I focus on the Kalandikaprakasa, composed between 1847 and 1850. A major treatise in wissenschaftliches and Sanskrit, it discusses knowledge, scientific and religious, that the author, a traditionally-educated Hindu pandit, deemed worthy of knowing. Importantly, this knowledge included a knowledge of Christianity. For an era rife with interreligious polemics, to advocate on behalf of Christianity as a religion worth knowing in relation to its …

The Neural Correlates Of Third-Party Punishment, Owen D. Jones, Joshua Buckholtz, Christopher L. Asplund, Paul E. Dux, David H. Zald, John C. Gore, Rene Marois

Vanderbilt Law School Faculty Publications

This article reports the discovery, from the first full-scale law and neuroscience experiment, of the brain activity underlying punishment decisions.

We used functional magnetic resonance imaging (fMRI) to measure brain activity of subjects as they read hypothetical scenarios about harm-causing protagonists and then decided whether to punish and, if so, how much.

The key variables were: a) presence or absence of excusing, justifying, or otherwise mitigating factors (such as acting under duress); and b) harm severity (which ranged from a stolen CD to a rape/murder/torture combination).

Findings include:

(1) Analytic and emotional brain circuitries are jointly involved, yet quite separately …

Democracy Uncaged, Suzanna Sherry

Vanderbilt Law School Faculty Publications

Sanford Levinson calls for a new constitutional convention in Our Undemocratic Constitution: Where the Constitution Goes Wrong (and How We the People Can Correct It). This review explains how Levinson overstates the Constitution's defects and understates the risks of submitting it to a constitutional convention for revision. It exposes the hidden biases in Levinson's analysis and defends the counter-majoritarian aspects of the Constitution that Levinson criticizes.

The Development Of A "Genetic Eyewitness" Profiling System For Low Template Forensic Specimens: Identification Of Novel Protein, Rna, And Dna Biomarkers, Erin Hanson

Electronic Theses and Dissertations

In many criminal investigations, valuable information regarding the physical appearance of suspected perpetrators or the time and order of events that transpired are provided by eyewitness accounts. However, the information obtained from eyewitnesses is often constrained by human recollection or subjective accounts and provides a biased description of the perpetrator's appearance or an inaccurate time line of events. Additionally, in numerous situations eyewitness accounts may not be available. An increasing reliance therefore is placed on the biological evidence recovered during criminal investigations to act as a silent witness, providing unbiased and scientific information that may aid in the resolution of …

Capitalism And The Tax System: A Search For Social Justice, Beverly I. Moran

Vanderbilt Law School Faculty Publications

America is a country founded on ideas. The Enlightenment was one set of ideas that attended our birth and one Enlightenment belief as strong today as during the revolution is our faith in capitalism and the protection of private property. Yet, the United States tax system manages to violate fundamental capitalist principles as outlined in the extensive writings of Adam Smith - the father of capitalism. Comparing Smith's vision to the current United States tax system reveals many important inconsistencies, particularly the current penchant for simultaneously taxing wages while exempting (or delaying) taxes on wealth and wealth appreciation. The article …

Analytical Modeling With Decoupled Optimal Control Of Biomechanical Sit -To -Stand Movement, Asif Mahmood Mughal

Theses and Dissertations

Biomechanical movements with multiple degrees of freedom exhibit complex coordination and control mechanisms in the presence of physiological constraints. A human body biomechanical model which can mimic diverse 3D physiological movements is a challenging task. In this study, we develop a mathematical framework to study human sit-to-stand (STS) movement using 2D biomechanical models. This analytical framework models the physiological system for feedback controller design. A 2D 4-segment biomechanical model with optimal feedback controller design provides a motivation to extend this scheme for analytical 3D bipedal modeling. We used a newly developed mathematical modeling toolbox (Maple’s DynaFlexPro) to generate 3D 8-segment …
