An Online Academic Support Model for Students Enrolled in Internet-Based Classes

Description: This doctoral dissertation describes a research study that examined the effectiveness of an experimental Supplemental Instruction (SI) program that utilized computer-mediated communication (CMC) rather than traditional SI review sessions. During the Spring 1999 semester, six sections of an introductory computer course were offered via the Internet by a suburban community college district in Texas. Using Campbell and Stanley's Nonequivalent Control Group model, the online SI program was randomly… more

Work-family responsiveness in organizations: The influence of resource dependence and institutionalization on program adaptation

Description: Changes in workforce demographics, employee sentiments, and working conditions have increased attention on employees' needs to balance the demands of work life and family life. Despite apparent growing interest among companies to be responsive to these needs, the number of companies demonstrating high levels of work-family responsiveness is relatively small. The frameworks of resource dependence theory and institutional theory were used to develop a model to explain differences in work-family r… more

Macroinvertebrate Community Structure as an Indicator of Watershed Health in the Upper Trinity River Basin, North Central Texas

Description: This study describes macroinvertebrate community structure and assesses its potential in detecting point and non-point sources of disturbance associated with rural and urban areas in the Upper Trinity River Basin. Geospatial techniques were used to quantify landuse within the watershed in a GIS. At rural sites near the headwaters of the Trinity River, collector-gathering burrowers that are adapted to minimal flow comprised the majority of taxa. Destinies of taxa compositions at downstream sites… more

Scanning Tunneling Microscopy of Homo-Epitaxial Chemical Vapor Deposited Diamond (100) Films

Description: Atomic resolution images of hot-tungsten filament chemical-vapor-deposition (CVD) grown epitaxial diamond (100) films obtained in ultrahigh vacuum (UHV) with a scanning tunneling microscope (STM) are reported. A (2x1) dimer surface reconstruction and amorphous atomic regions were observed on the hydrogen terminated (100) surface. The (2x1) unit cell was measured to be 0.51"0.01 x 0.25"0.01 nm2. The amorphous regions were identified as amorphous carbon. After CVD growth, the surface of the epita… more

The Cluster Hypothesis: A Visual/Statistical Analysis

Description: By allowing judgments based on a small number of exemplar documents to be applied to a larger number of unexamined documents, clustered presentation of search results represents an intuitively attractive possibility for reducing the cognitive resource demands on human users of information retrieval systems. However, clustered presentation of search results is sensible only to the extent that naturally occurring similarity relationships among documents correspond to topically coherent clusters. … more

The Validity of Health Claims on the World Wide Web: A Case Study of the Herbal Remedy Opuntia

Description: The World Wide Web has become a significant source of medical information for the public, but there is concern that much of the information is inaccurate, misleading, and unsupported by scientific evidence. This study analyzes the validity of health claims on the World Wide Web for the herbal Opuntia using an evidence-based approach, and supports the observation that individuals must critically assess health information in this relatively new medium of communication. A systematic search by mea… more

Conformational Studies of Myosin and Actin with Calibrated Resonance Energy Transfer

Description: Resonance energy transfer was employed to study the conformational changes of actomyosin during ATP hydrolysis. To calibrate the technique, the parameters for resonance energy transfer were defined. With conformational searching algorithms to predict probe orientation, the distances measured by resonance energy transfer are highly consistent with the atomic models, which verified the accuracy and feasibility of resonance energy transfer for structural studies of proteins and oligonucleotides. … more

An investigation of the relationships between job characteristics, satisfaction, and team commitment as influenced by organization-based self-esteem within a team-based environment

Description: Team-based management is a popular contemporary method of redesigning jobs in order to more effectively utilize the human potential of employees. The use of such management techniques should result in increased satisfaction and team commitment; however, many research studies have failed to demonstrate increases in affective outcomes on the part of the employee. The research question examined in this study is, "What specific job dimensions and situational factors result in higher levels of satis… more

Emotional Health, Well-Being, And Religion as Quest

Description: This study examined the relationship between the religious orientation quest and well-being using the 1998 General Social Survey. In addition to the religious orientation quest the extrinsic and intrinsic religious orientations were also investigated. Analysis of the data indicated that there was a slight negative association between quest and general well-being, while also demonstrating a strong positive association between quest and inner peace. These results underscore the supposition that q… more

Stretched Out On Her Grave: The Evolution of a Perversion

Description: The word "necrophilia" brings a particular definition readily to mind – that of an act of sexual intercourse with a corpse, probably a female corpse at that. But the definition of the word did not always have this connotation; quite literally the word means "love of the dead," or "a morbid attraction to death." An examination of nineteenth-century literature reveals a gradual change in relationships between the living and the dead, culminating in the sexualized representation of corpses at the … more

Characterizing the Municipal Solid Waste Stream in Denton, Texas

Description: Forty-two commercially collected dumpsters from Denton’s Municipal Solid Waste Stream were emptied, sorted and weighed to characterize the material types and make preliminary recycling policy recommendations. The general composition of Denton’s solid waste stream was not significantly different from the composition of the nation’s solid waste stream. Fifty-eight percent of the observed waste stream was recyclable. Paper made up the largest portion of recyclable materials and the "grocery" sourc… more

Relationship Between Flow Experience, Flow Dimensions, and the Equivalence of Challenges and Skills in the Web-Based Training Environment

Description: This study applied components of Csikszentmhalyi’s flow theory to the Web-based Training (WBT) environment. Specifically considered were how the equivalence of a learner’s perceived challenges and skills for an activity can effectively predict the emergence of flow in the WBT environment. Also considered was the ability of flow dimensions — defined in flow theory — to predict and model the occurrence of flow during WBT activities. Over a period of about one hour, students (n=43) from a southwes… more

Jezebel's Daughters: A Study of Wilkie Collins and His Female Villains

Description: The term "feminist," when applied to Wilkie Collins, implies he was concerned with rectifying the oppression of women in domestic life as well as with promoting equal rights between the sexes. This study explores Collins the "feminist" by analyzing his portrayals of women, particularly his most powerful feminine creations: his villainesses. Although this focus is somewhat limited, it allows for a detailed analysis of the development of Collins's attitudes towards powerful women from the beginni… more

The Application of a Health Service Utilization Model to a Low Income, Ethnically Diverse Sample of Women

Description: A model for health care utilization was applied to a sample of low income women. Demographic Predisposing, Psychosocial Predisposing, Illness Level, and Enabling indicators were examined separately for African American (n = 266), Anglo American (n = 200), and Mexican American (n = 210) women. Structural Equation Modeling revealed that for African American and Anglo American women, Illness Level, the only significant path to Utilization, had a mediating effect on Psychosocial Predisposing indica… more
