The Precipitation of Strontium Sulfate in Gels

Description: The growth of strontium sulfate precipitate by diffusion in various gels was studied by using optical transmission and confocal microscopies, scanning and transmission electron microscopies, and energy dispersive X ray fluorescence. Pure silica gel, pure agarose gel and the silica/agarose mixed gel at pH 7 - 10 were used throughout the present study. Precipitate morphology is sensitive to pH and to the nature of the growth medium. The morphology was observed as a function of time. The lack of change is presumably because of rapid depletion of the limiting reagent after the very beginning of precipitation. The problem of separating strontium sulfate precipitate from the gel medium is discussed.

Browning and Dickens: Religious Direction in Victorian England

Description: Many Nineteenth century writers experienced the withdrawal of God discussed by Miller in The Disappearance of God. Robert Browning and Charles Dickens present two examples of "Fra Lippo Lippi" and Great Expectations model effective alternatives to accepting God's absence. Conversely "Andrea del Sarto" accepts the void the other two heroes shun.

A Sythetic Study of a Cyclic Siloxydiyne and its Iron Carbonyl Complex

Description: The synthetic studies include the synthesis of the cyclic siloxydiyne, 3,3,5,5,8,8,10,10-octamethyl-4,9-dioxa-3,5,8,10-tetrasilacyclodeca-1,6- diyne [VI] and its novel iron carbonyl complex. In the preparation of [VI] by HBr promoted condensation of bis (methoxydimethylsilyl) acetylene, a minor product, a cyclic trimer was always formed along with the major product [VI]. No evidence of an equilibrium between the trimerization product and the dimerization product was found. Compound [VI] can react with iron carbonyl reagents to produce a novel binuclear iron complex of trimethylenemethane [VII] in very low yield either in a thermal or photo-reaction. The key step proposed by us in the formation of [VII] is a I,2-silyl shift in a complexed bis (silyl) acetylene to form a vinylidene intermediate. Experiments aimed at isolating this intermediate were not successful.

Charles Beard versus the Founding Fathers: Property Concepts in the Eighteenth Century

Description: This thesis deals with the role of property in the formation of the American Constitution and government. Charles Beard's views on property are compared with writings from the eighteenth century. Beard's writings on property and his critics are examined in the first two chapters. Then, the thesis's two historical contexts are evaluated. Concentrating on the Enclosure Acts, the fourth chapter looks at the importance of land to the former Englishmen. The eighteenth century view of property is the focus of the fifth section. The last chapter contrasts the two different views of property. Beard believed that the Constitution was a conservative document that protected the property of the few over the many. The Founding Fathers actually included liberal protections for property in the eighteenth century.

Linear Unification

Description: Efficient unification is considered within the context of logic programming. Unification is explained in terms of equivalence classes made up of terms, where there is a constraint that no equivalence class may contain more than one function term. It is demonstrated that several well-known "efficient" but nonlinear unification algorithms continually maintain the said constraint as a consequence of their choice of data structure for representing equivalence classes. The linearity of the Paterson-Wegman unification algorithm is shown largely to be a consequence of its use of unbounded lists of pointers for representing equivalences between terms, which allows it to avoid the nonlinearity of "union-find".

The Law and Its Enforcers in Faulkner's Trilogy

Description: This thesis evaluates how effectively the trilogy's laws and law enforcers further the ends of the fictional laws. The study examines the trilogy's law enforcers' responses to Snopes violations and bendings of the laws to evaluate the laws and their enforcers. The enforcers' responses to Snopes wrongs make clear how well the laws are written. These responses also reveal how well the enforcers themselves are able to achieve the objectives of the laws. It is argued in the thesis that although the laws are effectively written, the law enforcers fail to enforce the laws and, consequently, fail to achieve the laws' ends. It is also shown that the enforcers invariably harm innocent persons when they fail to enforce the law.

The Object-Oriented Database Editor

Description: Because of an interest in object-oriented database systems, designers have created systems to store and manipulate specific sets of abstract data types that belong to the real world environment they represent. Unfortunately, the advantage of these systems is also a disadvantage since no single object-oriented database system can be used for all applications. This paper describes an object-oriented database management system called the Object-oriented Database Editor (ODE) which overcomes this disadvantage by allowing designers to create and execute an object-oriented database that represents any type of environment and then to store it and simulate that environment. As conditions within the environment change, the designer can use ODE to alter that environment without loss of data. ODE provides a flexible environment for the user; it is efficient; and it can run on a personal computer.

Malaysian Natural Rubber Industry: An Econometric Analysis on the Elasticity of Supply and Demand Approaches

Description: The popularity of natural rubber as an important raw material was distorted in the post-World War Two period. It received heavy competition from synthetic rubber. The main purpose of this paper is to determine and to study supply elasticity and demand elasticity of natural rubber in the case of Malaysia. The main aim of analyzing the period since 1971 is that both price and quality competitiveness of Malaysian natural rubber have drastically improved. Therefore, in order for Malaysia to maintain her position as the leading producer and exporter of natural rubber in the world, supportive policies and incentives from the government would further enhance the prospects for improvements in this industry.

The Design and Function of the Interior Space of the Morton H. Meyerson Symphony Center of Dallas, 1980-1989

Description: This thesis investigates how the interior of the Morton H. Meyerson Symphony Center of Dallas accommodates the three groups which use the space: the patron, the musicians, and the administration. Following the Draft Brief of 1981 prepared by the Dallas Symphony Association's Concert Hall Building Committee, each area is discussed as to what was actually built and what concerns were met. The primary data were the symphony center and interviews with I.M. Pei, architect; Russell Johnson, acoustician of the concert hall; Charles Young, associate of Pei, Cobb, Freed & Associates, interior architect of the concert hall; Carolyn Miller, Trisha Wilson & Associates, designer of the Green Room, Richard Trimble, designer of the musicians' areas, and Joe Pereira, designer of the Administrative area.

Comparability of the WPPSI-R and the Stanford-Binet: Fourth Edition

Description: The purpose of this study was to compare the performance of children on the Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R) with their performance on the Stanford-Binet Intelligence Scale: Fourth Edition (SB:FE). One hundred and four children between 3 and 7 years of age were administered both tests. A moderate correlation was found between the WPPSI-R Full Scale IQ and the SB:FE Composite Score with a Pearson product-moment correlation of .46. This correlation suggests that the two tests are not interchangeable measures of children's intelligence. They may measure different, equally important aspects of intelligence. As both tests used are relatively new, the current findings should be considered one step in the accumulation of knowledge about the usefulness of the WPPSI-R.

Manipulation of Efficacy Information to Enhance Muscular Endurance Performance

Description: The present investigation was designed to examine the effects of the positive manipulation of information on self-efficacy and subsequent performance of 180 female subjects. High, moderate, and low self-efficacy subjects were randomly assigned to a treatment condition in a 3 x 4 x 3 (preexisting self-efficacy x efficacy information source x trials) factorial design. Information from the three efficacy sources of performance accomplishments, verbal persuasion, and vicarious experience was manipulated towards success after subjects completed a muscular leg endurance task. The results supported self-efficacy theory with high self-efficacy subjects extending their legs significantly longer than moderate and low self-efficacy subjects. However, subjects did not differentially [sic] respond to the manipulation of the efficacy information. Results are discussed in terms of efficacy as a mediator of performance on an endurance task as well as the lack of differential changes in efficacy based on the source from which that information is derived.

Sediment Bound Trace Metals in the White Rock Creek Watershed, Dallas and Collin Counties

Description: Areas were sampled in the White Rock Creek Watershed to examine sediment bound trace metal distributions and sorption relationships. A Kruskal-Wallis AOV found significant among area differences for most metals, and SNK-like multiple comparisons were used to group these areas. Kruskal-Wallis AOVs similarly found among area differences for sediment components that bind trace metals (Fe and Mn oxides and organic carbon) and physicochemical conditions that influence metal sorption (particle size and pH). Multiple correlation found numerous relationships among trace metals, sediment components, and physicochemical conditions. Statistical relationships indicate that metal partitioning to various sorption factors is metal specific. White Rock Creek Watershed trace metal concentrations are comparable to those in many urban watersheds.

The Relationship Between Race of Counselor, Cultural Mistrust Level and Willingness to Seek Psychological Treatment Among Mexican-American Adolescents

Description: The effects of cultural mistrust level and race of counselor on the willingness of Mexican-American adolescents to seek psychological help were examined in this experiment. A total of 79 Mexican-American adolescents consisting of 50 females and 29 males completed a Background Information Inventory, a modified version of the Cultural Mistrust Inventory, and the Help Seeking Attitude Scale. Five regression analyses were performed resulting in a significant interaction between cultural mistrust level and willingness to seek help. Mexican-American adolescents with high levels of mistrust were less willing to seek psychological treatment than those with a low level of mistrust. Results also indicated that females as well as individuals with higher levels of education were more willing to seek help than males and those with lower levels of education. Theoretical and practical implications are discussed.

Parental Attitudes Toward Human Sexuality Education in the Home and in the School

Description: To examine parental attitudes toward sexuality education in the home and school, sealed packets were distributed to fifth and seventh graders (N = 609) for each to deliver home to a parent. Parents were asked to express level of agreement with a series of attitude statements and to indicate the content and timing considered appropriate for sexuality instruction in the home and school. Analysis of 246 returned surveys (40% response rate) indicated that most parents trust the school to address human sexuality, though a sizeable minority of parents hold very conservative attitudes toward sexuality instruction in this setting. Results suggested that the majority of parents view school-based instruction as supplemental to instruction in the home.

Studies of the Interaction of LCAT with Lipoprotein Substrates in HDL Deficient Plasma Systems

Description: Enzymatic and lipid transfer reactions involved in reverse cholesterol transport were studied in HDL deficient plasma systems. Fasting plasma samples were obtained from control and cholesterol fed guinea pigs as well as from a fish eye disease patient and were used to localize the enzyme LCAT among plasma lipoproteins (VLDL, LDL, and HDL). In both guinea pig and fish eye disease patient plasma, the LCAT activity was found in association with the HDL type particles. Cholesterol feeding in guinea pigs altered the properties of lipoprotein substrates for LCAT resulting in some changes, specifically: 1) decreased fractional rate of plasma cholesterol esterification and, 2) lower transfer of free cholesterol (FC) and esterified cholesterol (CE) within the lipoprotein fractions.

Properties of R-Modules

Description: This thesis investigates some of the properties of R-modules. The material is presented in three chapters. Definitions and theorems which are assumed are stated in Chapter I. Proofs of these theorems may be found in Zariski and Samuel, Commutative Algebra, Vol. I, 1958. It is assumed that the reader is familiar with the basic properties of commutative rings and ideals in rings. Properties of R-modules are developed in Chapter II. The most important results presented in this chapter include existence theorems for R-modules and properties of submodules in R-modules. The third and final chapter presents an example which illustrates how a ring R, may be regarded as an R-module and speaks of the direct sum of ideals of a ring as a direct sum of submodules.

Militarization and Its Effects on Women's Economic Status: a Cross-National Study

Description: This research tested the hypothesis that militarization of societies, as defined by the percent of national budgets spent on military expenditures, has adverse effects on women's economic status relative to men's. This study also examined other predictor variables known to affect women's status. Data from sixty different nations were analyzed by means of multiple regression techniques. Results show that the militarization variable increased women's share of agriculture, which suggests that as men are mobilized into military activities, women are left to produce food for the country, a situation which can have contradictory effects on women's economic status. What is more important than militarization in predicting women's economic status relative to men's are high birth rates and sex ratios, which clearly depress women's economic opportunities.

Effects of Male and Female Speech Styles on the Perceptions of Clinical Psychologists

Description: Previous research suggests that gender-appropriate and gender-inappropriate use of sex-linked linguistic markers alters subjects' perceptions of the speaker. The present study examined the effects of male and female speech styles on clients' perceptions,. Undergraduates (N = 160) listened to audiotapes of clinical psychologists introducing the same client to psychotherapy. Clinician gender and sex-linked linguistic markers were manipulated. The results suggested that sex-stereotypes of males, females, and occupations played an important role in altering clients' perceptions of clinical psychologists. Sex-stereotypes did not, however, determine the desirability of the speaker as a therapist. The use of female speech styles increased the clinician's perceived femininity and desirability as a therapist.

Characterization of Human Glucose-6-Phosphate Isomerase of Different Sizes

Description: Glucose phosphate isomerase (GPI) was purified from human placenta utilizing cross-linked spherical particle phosphocellulose. In three steps, GPI could be purified approximately 5500 fold with greater than 50% recovery. The purified enzyme exhibited four bands upon non-denaturing PAGE and isoelectric focusing (IEF) when stained with GPI specific activity stain. The four isozymes were isolated by preparative IEF. The isoelectric points of the isozymes were determined. Sodium dodecyl sulfate (SDS) gel electrophoresis showed two types of subunits with different molecular weights. Structural analyses showed both types of subunits had blocked amino termini. Other properties of the isozymes and subunits, including immunological reactivity, pH stability, peptide mapping and amino acid composition, were also established.

Mistrust Level and Attitudes Toward Seeking Professional Psychological Help

Description: This study explored the relationship between cultural mistrust level and attitudes toward seeking professional psychological help. It was hypothesized that Blacks with high levels of cultural mistrust, when compared to those with low levels, would show less favorable attitudes toward seeking formal help for psychological problems. Black students were administered the Cultural Mistrust Inventory, Help-Seeking Attitude Scale, Reid-Gundlach Social Service Satisfaction Scale, and Opinions About Mental Illness Scale. Using a 2 (gender) X 2 (mistrust level) MANCOVA, a main effect for the factor of mistrust level was found along with a mistrust level by gender interaction. Students with higher levels of cultural mistrust were found to hold less favorable attitudes toward seeking professional psychological help when compared to students with lower levels of cultural mistrust.

The Comparison of Mandatory and Voluntary Compliance to Diet and Exercise Regimens Among Cardiovascular High Risk Seminary Theological Students

Description: This study evaluated a mandatory fitness assessment and counseling program designed to reduce coronary risk factors related to diet and exercise. The study was conducted at a southwestern graduate level theological institution. There were 19 mandatory and 22 voluntary participants. Each subject initially had either high blood pressure, high percentage body fat, or high total cholesterol. Significant changes were made within both groups regarding body fat percentage and diastolic blood pressure. Total cholesterol levels decreased for the voluntary group only. The mandatory group significantly improved their exercise level, yet still showed a significantly less positive attitude towards exercise. Overall, the fitness assessment and counseling was somewhat beneficial for both the mandatory and voluntary groups.
