Chemical Mechanism of the Catalytic Subunit of Camp-Dependent Protein Kinase: Methods for Determining the Primary ¹⁸O Isotope Effects Using the Remote Label Technique

Description: A description of the nature of the transition state structure for phosphoryl transfer in the cAPK reaction requires a measurement of the primary 180 isotope effect at the serine hydroxyl acceptor. Since it is difficult to obtain primary 180 isotope effect directly, the 15N/1 4N ratio of the a-amine of the C-terminal glycine in the peptide Leu Arg-Lys-Ala-Ser-Leu-Gly (when serine is phosphorylated) was used to represent on the phosphorylation at serine. 15N Glycine, ' 4N-Glycine and 180 serine w… more

Class and Freedom of Choice in the Marriage Patterns of Antebellum Texas Women

Description: Little scholarly analysis has been devoted to the hypothesis that antebellum Texas women generally married within their own socioeconomic (slaveholding) class, and thus had only limited choice in the selection of marriage partners. This quantitatively based investigation suggests that the popular image should be carefully qualified. This study reveals that although a majority of Texas women who married during the early 1850s chose men who had the same slaveholding status, a significant minority… more

Comparative Effectiveness of Paired Versus Individual Learning of Cognitive Skills Using Computer-Based Instruction

Description: This study examined the comparative effectiveness of learning of cognitive skills when instruction is presented through computer-based instruction using student-to-computer ratios of one-to-one and two-to-one. Effectiveness was gauged through scores on posttests administered subsequent to completion of each of nine computer-based lessons and on a single composite test score.

A Comparison of Measures of Signal-To-Noise Ratio, Jitter, Shimmer, and Speaking Fundamental Frequency in Smoking and Nonsmoking Females

Description: Fifteen nonsmoking and fifteen smoking females 19 to 36 years of age were evaluated on measures of signal-to-noise ratio (SNR), jitter, shimmer, and speaking fundamental frequency (F0). The results indicated that: 1) there is a significant difference between female smokers and nonsmokers on measures of SNR, mean, and maximum F0 and, 2) there is no significant difference between female smokers and nonsmokers on measures of jitter, shimmer and minimum F0 . The SNR was found to be a powerful tool … more

A Comprehensive Neuropsychological Screening Device for Adults: Reliability of Parallel Forms

Description: The purpose of the present study was to evaluate the reliability of parallel-forms of the Comprehensive Neuropsychological Screening Device (CNS). Forty-five subjects ranging in age from 16 to 69 were administered Form A and Form B of the CNS at two week intervals. Results indicated that the CNS has adequate test-retest reliability. The results suggest the applicability of using the CNS as a screening device for brain dysfunction.

Computer Simulations of Mechanical Behavior of Polymer Liquid Crystals

Description: In this dissertation molecular dynamics simulations of behavior of polymer liquid crystals (PLC's) under tensile deformation have been performed. PLC's composed of random or block copolymers of rigid and flexible segments have been studies. Systems of fully flexible chains have been simulated for comparison. Stress-strain relations and fracture mechanics have been investigated.

The Effects of Age-Graded Associations on the Political Activism of the Elderly

Some studies indicate that the elderly will soon develop the consensus needed for political action; other studies counter that the elderly will never be a viable political factor. Among the determinants listed as influencing the political participation equation are standard socioeconomic variables (e.g., race, soci… more

Efficient Parallel Algorithms and Data Structures Related to Trees

Description: The main contribution of this dissertation proposes a new paradigm, called the parentheses matching paradigm. It claims that this paradigm is well suited for designing efficient parallel algorithms for a broad class of nonnumeric problems. To demonstrate its applicability, we present three cost-optimal parallel algorithms for breadth-first traversal of general trees, sorting a special class of integers, and coloring an interval graph with the minimum number of colors.

The emergence and development of Browning's auditor

Description: By presenting the auditor as a unifying principle that links Browning's earliest works to his dramatic monologues, this dissertation enhances the importance of the ever-ignored experimental works in developing the dramatic monologue technique. An exploration of the emergence and development of the auditor has an additional, but never ancillary, effect of proclaiming the originality and inventiveness of Browning's dramatic technique.
