A Generalization of Sturmian Sequences: Combinatorial Structure and Transcendence

A Generalization of Sturmian Sequences: Combinatorial Structure and Transcendence

Date: August 1998
Creator: Risley, Rebecca N.
Description: We investigate a class of minimal sequences on a finite alphabet Ak = {1,2,...,k} having (k - 1)n + 1 distinct subwords of length n. These sequences, originally defined by P. Arnoux and G. Rauzy, are a natural generalization of binary Sturmian sequences. We describe two simple combinatorial algorithms for constructing characteristic Arnoux-Rauzy sequences (one of which is new even in the Sturmian case). Arnoux-Rauzy sequences arising from fixed points of primitive morphisms are characterized by an underlying periodic structure. We show that every Arnoux-Rauzy sequence contains arbitrarily large subwords of the form V^2+ε and, in the Sturmian case, arbitrarily large subwords of the form V^3+ε. Finally, we prove that an irrational number whose base b-digit expansion is an Arnoux-Rauzy sequence is transcendental.

Group Decision-Making in Computer-Supported Cooperative Work Environments

Group Decision-Making in Computer-Supported Cooperative Work Environments

Date: August 1998
Creator: Ayala-Bush, Mary T. (Mary Theresa)
Description: Computer-Support Cooperative Work (CSCW) reflects the change in emphasis from using computers to solve problems to using computers to facilitate human interactions. Most studies, however, have focused on the use of the technology rather than on the human-human interaction (HHI) in these environments due to: the varied perspectives of the investigators; and the lack of a consistent variables. Although numerous studies exist on a variety of products, only limited research has been conducted with the most prevalent of the technologies in the marketplace, Lotus Notes™. This field study, conducted using Lotus Notes™, operationalizes a model proposed, but not tested, for the study of group decision-making in CSCW environments put forth by Kraemer and Pinsonneault (1990). This study examines the use of CSCW in the group decision-making process, the participation rate for group decision-making in CSCW environments, and the criteria for determining quality in group decisions in CSCW environments. The study also proposes a new perspective for examining technology using the human context, recommends extensions for the group study framework and explores areas for future research.

A History of Contemporary Independent Film Marketing in the United States (1989-1998)

A History of Contemporary Independent Film Marketing in the United States (1989-1998)

Date: August 1998
Creator: Ahearn, John P. (John Patrick)
Description: This study explores the reasons for the rise in independent film's popularity, which have created a unique Hollywood phenomenon, the successful "mini-major" independent studio, dedicated to both art and commerce. Chapters cover the history of independent film, characteristics of both independent and mainstreamfilms with regards to financing, acquisition, distribution and marketing, trends within independent film in the late 1980s and 1990s, crucial distributors and landmark independent films, and key growth areas in the future for independent film.

Hormones, Distress, and Immune Functioning in Women

Hormones, Distress, and Immune Functioning in Women

Date: August 1998
Creator: Rubino-Watkins, Maria Francesca
Description: The present study set out to investigate the biopsychosocial model of illness using variables previously identified as directly impacting illness or as mediating the relationship between other variables and illness. Oral contraceptive use, stress, and negative affect were investigated as predictors of immunological competence, measured by the level of Immunoglobulin G antibodies to Epstein-Barr Virus Viral Capsid Antigen (EBV-VCA IgG).

Impact of Training on the Information Technology Attitudes of University Faculty

Impact of Training on the Information Technology Attitudes of University Faculty

Date: August 1998
Creator: Gilmore, Elizabeth L. (Elizabeth Lee)
Description: The purpose of this study was to determine whether training had an impact on the information technology attitudes of university faculty. The study was twofold. First, it sought to determine whether training changed attitudes toward information technology among faculty at a small, liberal arts university. Secondly, a group of faculty at a similar university was used to compare the differences in attitudes toward information technology among faculty who had received training and those who had not. The research population consisted of 218 faculty from these two universities. The literature review focused on obstacles to information technology use by faculty, instruments currently available for measuring faculty attitude, methods used in training faculty to use information technology, and integration of information technology by faculty.

Influence of Current Parent-Child Relationships on Dating Motivations in Young Adulthood

Influence of Current Parent-Child Relationships on Dating Motivations in Young Adulthood

Date: August 1998
Creator: Butcher, Karen H. (Karen Hunt)
Description: The purpose of this study was to explore how supportive functions of parent-child relationships influence young adult dating motivations and involvement. Theoretical literature suggests that emotionally supportive homes provide a secure base for children to depend on as they explore themselves and other relationships. However, problematic family ties could be expected to inhibit relationship involvement due to negative past experiences or to encourage involvement as a search for intimacy. A sample of 206 single, female undergraduates completed questionnaires assessing relationships with parents and aspects of romantic involvement and development. The set of Parent-Child Relationship variables included Support, Conflict, Depth, and Affective Quality in relationships with mother and father. The Attachment Related Dating Motivation variables included measures of Anxiety, Dependency, and Closeness in relationships, Attachment Motivation, Sexual Expression, Dating Exploration, Behavioral Indicators of Romantic Involvement, Sexual Involvement, and Level, Satisfaction, and Importance of Romantic Involvement.

The Influence of Parental Conflict on Late Adolescent Perceptions of Parental Support

The Influence of Parental Conflict on Late Adolescent Perceptions of Parental Support

Date: August 1998
Creator: Flint, Pamela
Description: The question addressed in this study is whether either parent's conflict style affected the supportive quality of the parents' relationship with the son or daughter. It was important to explore variables that affect support because supportive relationships with parents have been related to adolescent adjustment. Past studies have suggested parental conflict has a negative impact on the parent-adolescent relationship. Research in the area of mediators of perceived support in the parent-adolescent relationships is limited. This study focused on perceived support in the specific relationship of the parent and adolescent. Qualitative measures of conflict were used since they have been more strongly related to changes in parent-adolescent relationships than quantitative measures. In this study the supportive quality of the parent-adolescent relationship was operationalized as a measure of parental support, depth of the parent-adolescent relationship, and conflict in the parent-adolescent relationship (Quality of Relationship Inventory).

Investigating the Relationship Between Integrity and Job Turnover

Investigating the Relationship Between Integrity and Job Turnover

Date: August 1998
Creator: Simonini, Scott L.
Description: Integrity tests have become a widely used tool in modern-day selection systems. These instruments are generally designed to predict dishonest and counterproductive attitudes/behavior. A group of participants who had quit a job without notice was found to have higher scores on an Integrity/Pessimism scale (indicating low integrity and highly pessimistic attitudes) than an involuntary turnover group of those who had been fired or laid off. Post hoc analyses also found supporting evidence in that the quit without notice group also had higher expressed exit intentions scores (indicating negative attitudes toward current occupation/industry) and shorter average tenure than the involuntary (fired and laid off) group. The potential benefits of developing a predictive Integrity/Pessimism scale are discussed.

An Investigation of Factors Affecting Test Equating in Latent Trait Theory

An Investigation of Factors Affecting Test Equating in Latent Trait Theory

Date: August 1998
Creator: Suanthong, Surintorn
Description: The study investigated five factors which can affect the equating of scores from two tests onto a common score scale. The five factors studied were: (a) distribution type (i.e., normal versus uniform); (b) standard deviation of itemdifficulties (i.e., .68, .95, .99); (c) test length or number of test items (i.e., 50,100, 200); (d) number of common items (i.e., 10,20,30); and (e) sample size (i.e., 100, 300, 500). The significant two-way interaction effects were for common item length and test length, standard deviation of item difficulties and distribution type, and standard deviation of item difficulties and sample size.

Juan Bautista Maino's Adoration of the Shepherds: An Analysis of Iconography, Iconology, and Style

Juan Bautista Maino's Adoration of the Shepherds: An Analysis of Iconography, Iconology, and Style

Date: August 1998
Creator: Berry, Christine A. (Christine Alyce)
Description: This thesis investigates the iconography, iconology, and style of Juan Bautista Maino s Adoration of the Shepherds (1615-1620) located at the Meadows Museum, Dallas, Texas. The study begins with an overview of general information on Maino and his works. Chapter 2 explores the evolution of the Adoration of the Shepherds depiction in art, while examining social and political factors which may have influenced Maino's iconographical choices. Chapter 3 is a comparative analysis of the Meadows Adoration of the Shepherds to two other Adoration of the Shepherds by Maino, revealing a stylistic progression and presenting an argument for the dates the Meadows painting was rendered. Chapter 4 reviews the findings and suggests further study on this and other paintings by Maino.
