Neuropsychological Predictors of Incompetency to Stand Trial

Neuropsychological Predictors of Incompetency to Stand Trial

Date: December 2004
Creator: Grandjean, Nicole Rae
Description: This study investigated the effect of cognitive factors on competency to stand trial. Previous researchers have investigated how psychological variables --such as psychosis and intelligence--contribute to incompetency. Although several researchers have established that intelligence contributes to incompetency, very few have investigated the role of specific cognitive abilities within the realm of intelligence. This study investigated the performance of 55 defendants referred for competency restoration on neuropsychological measures. Specifically, competent defendants and incompetent defendants were compared on several measures assessing functioning in seven cognitive domains. Competent defendants performed significantly better than incompetent defendants on measures of verbal comprehension, social judgment, verbal memory, and executive functioning. Competent and incompetent defendants did not differ on attention, visual spatial skills, or nonverbal memory.

Neuroticism and Religious Coping Styles as Mediators of Depressive Affect and Perceived Stress

Neuroticism and Religious Coping Styles as Mediators of Depressive Affect and Perceived Stress

Date: August 2005
Creator: Crostley, Jeremy T.
Description: Previous researchers have shown that the collaborative, self-directing, and deferring styles of religious coping result in different outcomes of depression under different levels of perceived stress. Neuroticism has also been shown to affect coping effectiveness overall or choice of coping method. However, little work has been done to investigate the association between neuroticism and the choice or effectiveness of religious coping styles in particular, or on the association of neuroticism and perceived stress. The present study addressed research questions by examining relations among neuroticism, perceived stress, objective life events, religious and non-religious coping styles, effectiveness of coping styles, and depression. Hierarchical multiple regression and correlational techniques found that religious coping styles predict depression, religious and non-religious coping correspond, and neuroticism predicts perceived stress beyond situational stressors. Neuroticism did not predict use of religious coping styles, but remaining personality factors were successful in predicting coping. Implications, limitations, and future directions are discussed.

Neutron Density Depression Due to an Oblate Spheroidal Detector

Neutron Density Depression Due to an Oblate Spheroidal Detector

Date: January 1954
Creator: Trammell, Margaret Ruth
Description: In this paper, two projects have been undertaken. First, Workman's calculations have been checked to a higher degree of approximation to determine the accuracy of his method. Second, a new set of boundary conditions has been developed for obtaining solutions of the neutron diffusion equation which do not depend on the solution of the equation inside the detector.

Neutron Transmutation and Hydrogenation Study of Hg₁₋xCdxTe

Neutron Transmutation and Hydrogenation Study of Hg₁₋xCdxTe

Date: December 2007
Creator: Zhao, Wei
Description: Anomalous Hall behavior of HgCdTe refers to a "double cross-over" feature of the Hall coefficient in p-type material, or a peak in the Hall mobility or Hall coefficient in n-type material. A magnetoconductivity tensor approach was utilized to identify presence of two electrons contributing to the conduction as well as transport properties of each electron in the material. The two electron model for the mobility shows that the anomalous Hall behavior results from the competition of two electrons, one in the energy gap graded region near the CdZnTe/HgCdTe interface with large band gap and the other in the bulk of the LPE film with narrow band gap. Hg0.78Cd0.22Te samples grown by LPE on CdZnTe(111B)-oriented substrates were exposed to various doses of thermal neutrons (~1.7 x 1016 - 1.25 x 1017 /cm2) and subsequently annealed at ~220oC for ~24h in Hg saturated vapor to recover damage and reduce the presence of Hg vacancies. Extensive Magnetotransport measurements were performed on these samples. SIMS profile for impurities produced by neutron irradiation was also obtained. The purpose for this study is to investigate the influence of neutron irradiation on this material as a basis for further study on HgCdTe74Se. The result shows that total ...

Never Odd Or Even: Using Temporal Structures In Composing Music For Dance

Never Odd Or Even: Using Temporal Structures In Composing Music For Dance

Date: May 2012
Creator: Bernardo, Daniel
Description: This study engages the collaboration of dance and music, focusing primarily on experiences in the production of a large scale collaborative concert entitled Never Odd or Even. Famous historical collaborations offer archetypal collaborative models, the more unconventional of which are applied to the pieces of the concert. Issues and observations regarding cross-influence, project evolution, and application of the collaborative models are engaged to determine effective means of collaboration given different circumstances. The key focus of the study, the temporal relationship between music and dance, is explored in great detail to determine three models for relating time between music and dance. These temporal relationship models are applied to the pieces and evaluated on effectiveness and potential strengths when applied to dance.

Creator: Dong, Zhiming (Eric)
Description: I. Diels-Alder reactions of 1,2,3,4,9,9-hexachloro-1,4,4a,8a-tetrahydro-1,4-metha- nonaphthalene (16) and 1,2,3,4,9,9-hexachloro-1,4,6,7-tetrahydro-1,4-methanonaphthalene (17) toward dienophiles N-methyl-1,2,4-triazoline-3,5-dione (MTAD), N-phenyl-1,2,4-triazoline-3,5-dione (PTAD) and/or N-methylmaleimide (NMM) have been examined. II. Epoxides derived from functionalized 1,4,4a,9a-tetrahydro-9,10-dioxo-1,4-methanoanthracenes (1a and 1b) undergo acid- and base-promoted intramolecular nucleophilic ring-opening to form new polycyclic alcohols. III. The title cycloalkylidenecarbene has been generated via reaction of 8-methylenepentacyclo[5.4.0.0^{2,6}.0^{3,10}. 0^{5.9}]undecan-11-one (44) with diethyl diazomethyl-phosphonate (DAMP). This species could be trapped in situ by cyclohexene, thereby affording the corresponding cycloadduct 46a and 46b.

A New Algorithm for Finding the Minimum Distance between Two Convex Hulls

A New Algorithm for Finding the Minimum Distance between Two Convex Hulls

Date: May 2009
Creator: Kaown, Dougsoo
Description: The problem of computing the minimum distance between two convex hulls has applications to many areas including robotics, computer graphics and path planning. Moreover, determining the minimum distance between two convex hulls plays a significant role in support vector machines (SVM). In this study, a new algorithm for finding the minimum distance between two convex hulls is proposed and investigated. A convergence of the algorithm is proved and applicability of the algorithm to support vector machines is demostrated. The performance of the new algorithm is compared with the performance of one of the most popular algorithms, the sequential minimal optimization (SMO) method. The new algorithm is simple to understand, easy to implement, and can be more efficient than the SMO method for many SVM problems.

A New Approach for Transition Metal Free Magnetic Sic: Defect Induced Magnetism After Self-ion Implantation

A New Approach for Transition Metal Free Magnetic Sic: Defect Induced Magnetism After Self-ion Implantation

Date: May 2013
Creator: Kummari, Venkata Chandra Sekhar
Description: SiC has become an attractive wide bandgap semiconductor due to its unique physical and electronic properties and is widely used in high temperature, high frequency, high power and radiation resistant applications. SiC has been used as an alternative to Si in harsh environments such as in the oil industry, nuclear power systems, aeronautical, and space applications. SiC is also known for its polytypism and among them 3C-SiC, 4H-SiC and 6H-SiC are the most common polytypes used for research purposes. Among these polytypes 4H-SiC is gaining importance due to its easy commercial availability with a large bandgap of 3.26 eV at room temperature. Controlled creation of defects in materials is an approach to modify the electronic properties in a way that new functionality may result. SiC is a promising candidate for defect-induced magnetism on which spintronic devices could be developed. The defects considered are of room temperature stable vacancy types, eliminating the need for magnetic impurities, which easily diffuse at room temperature. Impurity free vacancy type defects can be created by implanting the host atoms of silicon or carbon. The implantation fluence determines the defect density, which is a critical parameter for defect induced magnetism. Therefore, we have studied the influence ...

A New Approach to Measurement of Partial Knowledge

A New Approach to Measurement of Partial Knowledge

Date: August 1973
Creator: Wagner, David E.
Description: The problem of this study is that of developing a testing procedure for multiple-choice tests which would increase the relationship between test scores and a criterion. The procedure investigated in this research was one in which subjects took a multiple-choice test but were required to continue responding on each item until the correct answer was obtained. The total number of responses was used as the score on the test. The purpose of this research was to investigate the possibility of increasing predictability by changing the procedure of administering the test, rather than changing the test itself.
