Stoichiometry and Deposition Temperature Dependence  of the Microstructural and Electrical Properties of Barium Strontium Titanate Thin Films

Stoichiometry and Deposition Temperature Dependence of the Microstructural and Electrical Properties of Barium Strontium Titanate Thin Films

Date: May 1998
Creator: Pena, Piedad
Description: Barium Strontium Titanate (BST) was deposited on Pt/ZrO2 / SiO2/Si substrates using liquid source metal organic chemical vapor deposition. A stoichiometry series was deposited with various GrII/Ti ratios (0.658 to 1.022) and a temperature series was deposited at 550 to 700°C. The thin films were characterized using transmission electron microscopy. Both series of samples contained cubic perovskite BST and an amorphous phase. The grain size increased and the volume fraction of amorphous phase decreased with increasing deposition temperature. The electrical and microstructural properties improved as the GrII/Ti ratio approached 1 and deteriorated beyond 1. This research demonstrates that BST thin films are a strong candidate for future MOS transistor gate insulator applications.

Masculine Role Conflict in Gay Men: Mediation of Psychological Well-Being and Help-Seeking Behaviors

Masculine Role Conflict in Gay Men: Mediation of Psychological Well-Being and Help-Seeking Behaviors

Date: August 1998
Creator: Simonsen, Gregory
Description: Gender role issues have been an integral part of psychology since the 1970s. More recently, theories and research have surfaced concerning the issues of maleness in our society. Most of these theories focus on masculine gender role and how it affects men in various ways, e.g., their psychological well-being, substance use, relational abilities, and help-seeking behaviors. One area of maleness that has consistently been left out of the Masculine Role Conflict (MRC) debate is that of homosexuality. As a gay man develops, he finds himself at odds with society over something that he experiences biologically as normal and appropriate. It is the contention of this paper that MRC is an issue related to psychological distress among gay men and not psychological weakness in gay men, per se.

The Effect of Giving Class Time for Reading on the Reading Achievement of Fourth Graders and the Effect of Using a Computer-Based Reading Management Program on the Reading Achievement of Fifth Graders

The Effect of Giving Class Time for Reading on the Reading Achievement of Fourth Graders and the Effect of Using a Computer-Based Reading Management Program on the Reading Achievement of Fifth Graders

Date: May 1998
Creator: Peters, Rochelle
Description: This study investigated the problem that educators have throughout the state of Texas. The problem educators have is that reading scores continue to fall short of state expectations. This study investigated the effectiveness of 90 minutes of class time given for reading to students who use the Electronic Bookshelf Program and the effectiveness of the Electronic Bookshelf Program, which is being sold to school districts throughout the nation. The literature review focused on the effectiveness of independent reading on reading achievement, and the effectiveness of using computer-based reading programs to increase reading achievement.

Susceptibility of College Students to Alcohol Abuse and Alcohol Related Problems: the Impact of Family Environmental Factors

Susceptibility of College Students to Alcohol Abuse and Alcohol Related Problems: the Impact of Family Environmental Factors

Date: December 1998
Creator: Blue, James M. (James Michael)
Description: The purpose of this study was to examine the impact of parental divorce, level of family conflict, and family history of alcoholism on the alcohol use patterns of college students. Gender differences were also explored. Multivariate Analysis of Variance revealed mixed results. Parental marital status was found to have no significant effect on college students' alcohol behavior. High family conflict had a significant impact on both level of current alcohol use and level of alcohol related problems. A positive family history of alcoholism was found to have effects on the level of alcohol related problems encountered by students. Gender played a significant role, with males reporting higher levels of alcohol-related problems. No significant interactions were found. Results, contributions and limitations of the study are discussed.

Creating a Mythistory: Texas Historians in the Nineteenth Century

Creating a Mythistory: Texas Historians in the Nineteenth Century

Date: August 1998
Creator: McLemore, Laura Lyons, 1950-
Description: Many historians have acknowledged the temptation to portray people as they see themselves and wish to be seen, blending history and ideology. The result is "mythistory." Twentieth century Texas writers and historians, remarking upon the exceptional durability of the Texas mythistory that emerged from the nineteenth century, have questioned its resistance to revision throughout the twentieth century. By placing the writing of Texas history within the context of American and European intellectual climates and history writing generally, from the close of the eighteenth century to the beginning of the twentieth, it is possible to identify a pattern that provides some insight into the popularity and persistence of Texas mythistory.

An Exploratory Investigation of the Origins and Regulatory Actions of the United Kingdom's Financial Reporting Review Panel

An Exploratory Investigation of the Origins and Regulatory Actions of the United Kingdom's Financial Reporting Review Panel

Date: December 1998
Creator: Styles, Alan K. (Alan Keith)
Description: In 1990, the accounting profession and the British government worked together to establish a new regulatory framework for financial reporting in the United Kingdom (UK), the Financial Reporting Council (FRC) and its two subsidiaries, the Accounting Standards Board (ASB) and the Financial Reporting Review Panel (FRRP). The FRRP enforces companies' compliance with the ASB's accounting standards and the accounting provisions of the UK Companies Act. Only one study, Brandt et al. (1997), has examined the activities and effectiveness of the FRRP. This dissertation attempts to extend Brandt et. al (1997) and add to understanding of the origins and regulatory actions of the FRRP.

Natural Smooth Measures on the Leaves of the Unstable Manifold of Open Billiard Dynamical Systems

Natural Smooth Measures on the Leaves of the Unstable Manifold of Open Billiard Dynamical Systems

Date: December 1998
Creator: Richardson, Peter A. (Peter Adolph), 1955-
Description: In this paper, we prove, for a certain class of open billiard dynamical systems, the existence of a family of smooth probability measures on the leaves of the dynamical system's unstable manifold. These measures describe the conditional asymptotic behavior of forward trajectories of the system. Furthermore, properties of these families are proven which are germane to the PYC programme for these systems. Strong sufficient conditions for the uniqueness of such families are given which depend upon geometric properties of the system's phase space. In particular, these results hold for a fairly nonrestrictive class of triangular configurations of scatterers.

The Rhetoric of Posthumanism in Four Twentieth-Century International Novels

The Rhetoric of Posthumanism in Four Twentieth-Century International Novels

Date: August 1998
Creator: Lin, Lidan
Description: The dissertation traces the trope of the incomplete character in four twentieth-century cosmopolitan novels that reflect European colonialism in a global context. I argue that, by creating characters sharply aware of the insufficiency of the Self and thus constantly seeking the constitutive participation of the Other, the four authors E. M. Forster, Samuel Beckett, J. M. Coetzee, and Congwen Shen all dramatize the incomplete character as an agent of postcolonial resistance to Western humanism that, tending to enforce the divide between the Self and the Other, provided the epistemological basis for the emergence of European colonialism. For example, Fielding's good-willed aspiration to forge cross-cultural friendship in A Passage to India; Murphy's dogged search for recognition of his Irish identity in Murphy; Susan's unfailing compassion to restore Friday's lost speech in Foe; and Changshun Teng, the Chinese orange-grower's warm-hearted generosity toward his customers in Long River--all these textual occasions dramatize the incomplete character's anxiety over the Other's rejection that will impair the fullness of his or her being, rendering it solitary and empty. I relate this anxiety to the theory of "posthumanism" advanced by such thinkers as Marx, Bakhtin, Sartre, and Lacan; in their texts the humanist view of the individual ...
