Electroencephalographic Events During the Wisconsin Card Sorting Test

Electroencephalographic Events During the Wisconsin Card Sorting Test

Date: August 1998
Creator: DeBeus, Mary
Description: Quantitative electroencephalography (QEEG) was used in this study to describe cognitive processing, particularly brain locations used, during performance of the Wisconsin Card Sorting Test (WCST). The hypothesis was that significant cognitive functioning is not limited to the frontal lobes. Significant EEG activity was found in non-frontal areas as well as frontal areas.

An Empirical Investigation of Personal and Situational Factors That Relate to the Formation of Entrepreneurial Intentions

An Empirical Investigation of Personal and Situational Factors That Relate to the Formation of Entrepreneurial Intentions

Date: August 1998
Creator: Summers, David F. (David Frederic), 1948-
Description: New entrepreneurial organizations emerge as a result of careful thought and action. Therefore, entrepreneurship may be considered an example of planned behavior. Previous research suggests that intentions are the single best predictor of planned behavior. Given the significance of intentions, the purpose of this study was to investigate the relationships between the personal characteristics of the entrepreneur and perceived environmental factors, and entrepreneurial intentions.

Evaluation of Sequential Events in Phagocytosis by Earthworm Coelomocytes as Potential Immunotoxicity Biomarkers

Evaluation of Sequential Events in Phagocytosis by Earthworm Coelomocytes as Potential Immunotoxicity Biomarkers

Date: August 1998
Creator: Murray, Stephanie Mae
Description: This research evaluated the potential of activation and attachment, as sequential companion biomarkers of phagocytosis by earthworm, Lumbricus terrestris, immunoactive coelomocytes for use in immunotoxicology. The potential was assessed by exposing earthworms to sublethal concentrations of CuSO4 and Arochlor 1254®, chemicals used as reference or standard immunotoxicants.

An Examination of the Criterion-Related Validity of a Developmental Assessment Center

An Examination of the Criterion-Related Validity of a Developmental Assessment Center

Date: August 1998
Creator: Yurkon, Andrew C.
Description: The purpose of this study was to investigate the criterion-related validity of an assessment center's competency dimension ratings, exercise ratings, and standardized test scores. Numerous studies have clearly demonstrated assessment centers display substantial evidence of content and criterion-related validity. However, the inability of assessment centers to display construct-related validity has caused a great deal of concern among researchers. The suggestions of these researchers are addressed through a more detailed examination of the criterion-related validity of an assessment center. Despite a number of methodological issues, two competency dimensions and two components stand out as viable predictors of the criteria used in this study. Examination of individual and incremental validity coefficients reveals the Strategic Focus and Attracting and Developing Talent competency dimensions, the In-Basket exercise, and the Watson-Glaser scaled score consistently predict the criteria used in this study. The implications of these results for future research are discussed.

Filial Therapy with Non-Offending Parents of Children Who Have Been Sexually Abused

Filial Therapy with Non-Offending Parents of Children Who Have Been Sexually Abused

Date: August 1998
Creator: Costas, Mary Bassett
Description: This study was designed to determine the effectiveness of filial therapy as a method of intervention for non-offending parents and their children who have experienced sexual abuse. Filial therapy is a didactic/dynamic approach used by play therapists to train parents to be therapeutic agents with their children. Parents are taught basic child-centered play therapy skills and the utilization of these skills in weekly play sessions with their children. Parents learn to create a special environment which enhances and strengthens the parent-child relationship, thus assisting in personal growth and change for both the parent and child. The purpose of this study was to determine if filial therapy is effective in: (a) increasing the acceptance of non-offending parents of their sexually abused children; (b) reducing the stress level of non-offending parents; (c) improving empathic behaviors of non-offending parents toward their sexually abused child; (d) decreasing the anxiety of sexually abused children; (e) enhancing the self-concept of sexually abused children; (f) decreasing behavior problems of sexually abused children as reported by their non-offending parents; and (g) enhancing the emotional adjustment of sexually abused children.

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).
