Contributing Risk Factors in the Association Between Sexual Abuse Experiences and Disturbed Eating Patterns in College Females (open access)

Contributing Risk Factors in the Association Between Sexual Abuse Experiences and Disturbed Eating Patterns in College Females

This study examined two theoretical factors proposed to explain the relationship between sexual abuse experiences and disturbed eating patterns. Over 300 women completed questionnaires designed to assess sexual abuse histories, bodily shame, body disparagement, and disordered eating behaviors. Multivariate analyses indicated that bodily shame, body image dysphoria, and bodily dissatisfaction were significantly higher in participants with previous sexual violations. In addition, disordered eating symptoms and behaviors were related to reported severity of sexual abuse experiences. However, the relationship between the severity of disturbed eating patterns and sexual abuse histories appears to be more meaningful in relation to the presence of bodily shame and body dissatisfaction, as proposed in previous research. Future research implications are discussed.

Control over Therapist Interactions as a Reinforcer for a Child with Autism (open access)

Control over Therapist Interactions as a Reinforcer for a Child with Autism

This study evaluated whether therapist terminations of social interactions would decrease social terminations and increase social initiations during play activities with a child with autism. The assessment took place in two conditions. The first condition, instructed involved social interactions with instructions delivered, and the second, uninstructed, involved social interactions without instructions delivered. These conditions were analyzed with a multiple baseline across-conditions design. Interaction duration, initiations, instructions, and child terminations were recorded. This study showed that the therapist-removal procedure resulted in a complete decrease in child terminations, and an increase in the number of initiations and the duration of the child-therapist interactions during the uninstructed condition. Similar effects were seen in the instructed condition, but to a lesser degree.

Counselor Effectiveness and Correlations With Select Demographic Variables for Masters Level Counseling Students

Access: Use of this item is restricted to the UNT Community
Counselor education programs are charged with the responsibility to train students to be effective counselors. Despite relative consistency in academic and clinical experiences, some students are less effective than others. It was the intent of this research to investigate possible relationships which may exist between students' background and experiences and their levels of demonstrated counselor effectiveness as measured by the Counselor Rating Form - Short Version (CRF-S) and the Supervisor Rated-Counselor Interaction Analysis (SR-CIA). It was hypothesized that counselor effectiveness would be negatively correlated with prior teaching experience and level of religious participation. Data was collected using a demographic survey from masters level counseling students participating in their practicum semester. Counseling tapes from each of the participants were collected towards the end of the semester. These tapes were then rated by doctoral students using the CRF-S and the SR-CIA. The total sample size was 28. Regression analysis was used to investigate the hypotheses. Three models were constructed. The dependent variables used were scores from the CRF-S, the SR-CIA and a third comprised of a normalized composite of CRF-S and SR-CIA termed COMPOSITE. Each model used, as the independent variables, years of teaching experience, and hours of religious participation. Results from …

Countable Additivity, Exhaustivity, and the Structure of Certain Banach Lattices (open access)

Countable Additivity, Exhaustivity, and the Structure of Certain Banach Lattices

The notion of uniform countable additivity or uniform absolute continuity is present implicitly in the Lebesgue Dominated Convergence Theorem and explicitly in the Vitali-Hahn-Saks and Nikodym Theorems, respectively. V. M. Dubrovsky studied the connection between uniform countable additivity and uniform absolute continuity in a series of papers, and Bartle, Dunford, and Schwartz established a close relationship between uniform countable additivity in ca(Σ) and operator theory for the classical continuous function spaces C(K). Numerous authors have worked extensively on extending and generalizing the theorems of the preceding authors. Specifically, we mention Bilyeu and Lewis as well as Brooks and Drewnowski, whose efforts molded the direction and focus of this paper. This paper is a study of the techniques used by Bell, Bilyeu, and Lewis in their paper on uniform exhaustivity and Banach lattices to present a Banach lattice version of two important and powerful results in measure theory by Brooks and Drewnowski. In showing that the notions of exhaustivity and continuity take on familiar forms in certain Banach lattices of measures they show that these important measure theory results follow as corollaries of the generalized Banach lattice versions. This work uses their template to generalize results established by Bator, Bilyeu, and …

Cure Kinetics and Processing Parameters of Neat and Reinforced High Performance Epoxy Resins: Evaluation of Techniques

Access: Use of this item is restricted to the UNT Community
Kinetic equation parameters for the curing reaction of a commercial glass fiber reinforced high performance epoxy prepreg composed of the tetrafunctional epoxy tetraglycidyl 4,4-diaminodiphenyl methane (TGDDM), the tetrafunctional amine curing agent 4,4’-diaminodiphenylsulfone (DDS) and an ionic initiator/accelerator, are determined by various thermal analysis techniques and the results compared. The reaction is monitored by heat generated determined by differential scanning calorimetry (DSC). The changes in physical properties indicating increasing conversion are followed by shifts in glass transition temperature determined by DSC and temperature-modulated DSC (TMDSC), thermomechanical (TMA) and dynamic mechanical (DMA) analysis and thermally stimulated depolarization (TSD). Changes in viscosity, also indicative of degree of conversion, are monitored by DMA. Thermal stability as a function of degree of cure is monitored by thermogravimetric analysis (TGA). The parameters of the general kinetic equations, including activation energy and rate constant, are explained and used to compare results of various techniques. The utilities of the kinetic descriptions are demonstrated in the construction of a useful time-temperature-transformation (TTT) diagram for rapid determination of processing parameters in the processing of prepregs.

Current and Future Trends in Computer Use in Elementary School Settings (open access)

Current and Future Trends in Computer Use in Elementary School Settings

The study examined current and future trends in computer use in elementary school settings. A survey instrument was developed and validated for distribution to a random sample of 200 technology coordinators in the public school districts in the state of Texas from whom 95 responses were received. The survey instrument was used to obtain information about five areas of computer use in elementary schools. These areas are: physical configurations, instructional uses, implementation issues, training and staff development, and Internet use. The study found that all public school districts that participated in the study have acquired computer hardware in their elementary schools. In addition, some other advanced computer technology components are starting to be found in elementary schools, such as teacher workstations, CD-ROM, interactive video, computer multimedia, LCD panels, and laser printers. Respondents reported that elementary school teachers in their districts have incorporated computers into their classrooms as an instructional tool and many changes have occurred in teachers’ teaching styles due to computers. However, there are some problems that hinder the effective use of computers. The major problem is lack of training. A high percentage of respondents, 81.3%, indicated that the majority of their elementary school teachers had completed less than …

Customer Induced Uncertainty and Its Impact on Organizational Design (open access)

Customer Induced Uncertainty and Its Impact on Organizational Design

How firms facing environmental uncertainty should organize their activities remains an important and challenging question for today's managers and organizational researchers. Proponents of contingency theory have argued that organizations must adjust their activities to fit the level of environmental uncertainty to ensure long-term survival. Although much work has been done on contingency theory, it is clear that our understanding of uncertainty is far from complete. One important aspect of today's organizations is their focus on service, mass customization, and continuous innovation. This focus often results in the customer being brought either into the organization or at least into closer contact with it. Even though the literature provides numerous evidences of the increasing customer focus, it is yet to empirically explain how the complications of customer-organizational interactions might create uncertainty for contemporary organizations. The traditional measure of uncertainty still considers customers as an environmental factor causing demand uncertainty while ignoring the complex nature of customer and organizational encounters. Seeking to further refine the concept of uncertainty and focusing on the contemporary business phenomena, this study develops measures aspects of customer induced uncertainty and examines their relationships with three organizational design variables. Specifically, this study explains the complicated nature of customer - …

As Darkness Falls: A Composition for Wind Ensemble

Access: Use of this item is restricted to the UNT Community
As Darkness Falls is a composition that explores our interaction with several aspects of darkness through the use of musical imagery. The imagery attempts to reflect the moods, feelings, and impressions of a person as he or she interacts with darkness. The non-programmatic character of the composition allows listeners to superimpose their own experiences onto the musical tapestry in order to manifest a personal connection between the listener and the music. As Darkness Falls is a composition scored for a minimum instrumentation of piccolo, 6 flutes, 3 oboes, 3 bassoons, 9 B-flat clarinets, B-flat bass clarinet, 2 E-flat alto saxophones, B-flat tenor saxophone, E-flat baritone saxophone, 4 B-flat trumpets, 4 horns in F, 3 tenor trombones, bass trombone, 2 euphoniums, 2 tubas, timpani, and 4 percussionists. The music consists of three movements (slow-slow-fast) lasting a total of approximately seventeen minutes. The duration of each of the three movements is six minutes, four and one-half minutes, and six and one-half minutes, respectively. The document also contains an analysis of the work by the composer. The analysis explores the compositional style of the work, focusing on musical aspects within each movement that were governing parameters in the compositional process.

A Descriptive Study of Students Who Were Accepted for Admission at West Texas A&M University But Did Not Enroll

Access: Use of this item is restricted to the UNT Community
Each year, institutions of higher education devote valuable financial and personnel resources in the hope of enhancing student recruitment and matriculation. The purpose of this study was to examine the demographic characteristics, the factors that influenced students’ decisions to apply for admission to a university, their educational intentions, and their reasons for not enrolling after they had been admitted. The subjects of the study were first-time freshmen accepted for admission to a mid-size, public, southwestern university who did not enroll for the fall 1997 semester. Statistically significant differences were found when comparing no-shows and enrolled students by gender, ethnicity, age, ACT/SAT score, and distance of their hometown from the university. There were more female no-shows, and more males enrolled than females; a greater percentage of no-shows reported the distance of their hometown to be more than 200 miles; and the mean test score for no-shows was higher. Factors important in the college selection process found to be statistically significant among the groups were: a greater percentage of Minorities than Caucasians reported the importance of the financial aid award or a scholarship offer; students living within 100 miles of the campus reported the proximity of the university as important, advice received …

Design of a Monitoring System for a Plasma Cleaning Machine (open access)

Design of a Monitoring System for a Plasma Cleaning Machine

Plasma cleaning is the most effective dry process to remove surface contaminates from a SAW (Surface Acoustical Wave) device. Consistent gas pressures, flows, and good electrical connections between the chamber shelves are necessary for the process to function predictably. In addition, operation of the monitoring system must be transparent to the plasma cleaning unit. This thesis describes a simple solution to the complex problem of monitoring a plasma cleaning system. The monitoring system uses the LabVIEW® G programming language and hardware, both products of National Instruments, Inc.®, to monitor critical parameters necessary to achieve a consistent process when cleaning these devices.

Developing Criteria for Extracting Principal Components and Assessing Multiple Significance Tests in Knowledge Discovery Applications (open access)

Developing Criteria for Extracting Principal Components and Assessing Multiple Significance Tests in Knowledge Discovery Applications

With advances in computer technology, organizations are able to store large amounts of data in data warehouses. There are two fundamental issues researchers must address: the dimensionality of data and the interpretation of multiple statistical tests. The first issue addressed by this research is the determination of the number of components to retain in principal components analysis. This research establishes regression, asymptotic theory, and neural network approaches for estimating mean and 95th percentile eigenvalues for implementing Horn's parallel analysis procedure for retaining components. Certain methods perform better for specific combinations of sample size and numbers of variables. The adjusted normal order statistic estimator (ANOSE), an asymptotic procedure, performs the best overall. Future research is warranted on combining methods to increase accuracy. The second issue involves interpreting multiple statistical tests. This study uses simulation to show that Parker and Rothenberg's technique using a density function with a mixture of betas to model p-values is viable for p-values from central and non-central t distributions. The simulation study shows that final estimates obtained in the proposed mixture approach reliably estimate the true proportion of the distributions associated with the null and nonnull hypotheses. Modeling the density of p-values allows for better control of …

Development and Validation of the Checklist for Differential Diagnosis of Attentional Problems (open access)

Development and Validation of the Checklist for Differential Diagnosis of Attentional Problems

The current study discussed the development and validation of the Checklist for Differential Diagnosis of Attentional Problems (CDDAP), a tool for use with adults seeking diagnosis and treatment of an Attention Deficit Hyperactivity Disorder. Normative data are provided on three subject groups (ADHD adults, controls, and adults with other psychiatric disorders). Convergent validity was established with the SCL-90, and criterion validity established through comparing scaled scores with final diagnoses. Overall, this measure was accurate at differentiating adults with ADHD from controls and adults with other psychiatric disorders. Results indicated that the CDDAP was also able to identify other psychiatric disorders with 71 to 92% accuracy, depending on the disorder.

Development and Validity of the Teachers' Attitude, Comfort and Training Scale (TACTS) on Sexuality Education (open access)

Development and Validity of the Teachers' Attitude, Comfort and Training Scale (TACTS) on Sexuality Education

The purpose of the study was to design and validate an instrument designed to investigate teachers' attitudes in regard to adolescent sexuality education. Test development adhered to the guidelines of Aligna and Crocker. Cronbach alpha was performed on the entire instrument and determined the reliability to be .8003, thus the instrument was consistent in measuring the domain areas. A panel of experts assessed content validity of items. A principal component factor analysis and a Pearson's product moment correlation were used for construct validity. Teacher concerns about curriculum implementation, teacher comfort with the subject matter, course-specific teacher attitudes, teacher interest about curriculum content, and teacher attitudes toward sexuality were found to be the constructs of the TACTS.

Development of a Coaxiality Indicator

Access: Use of this item is restricted to the UNT Community
The geometric dimensioning and tolerancing concept of coaxiality is often required by design engineers for balance of rotating parts and precision mating parts. In current practice, it is difficult for manufacturers to measure coaxiality quickly and inexpensively. This study examines feasibility of a manually-operated, mechanical device combined with formulae to indicate coaxiality of a test specimen. The author designs, fabricates, and tests the system for measuring coaxiality of holes machined in a steel test piece. Gage Repeatability and Reproducibility (gage R&R) and univariate analysis of variance is performed in accordance with Measurement System Analysis published by AIAG. Results indicate significant design flaws exist in the current configuration of the device; observed values vary greatly with operator technique. Suggestions for device improvements conclude the research.

Development of Cardiovascular Regulation in Embryos of the Domestic Fowl (Gallus Gallus), with a Partial Comparison to Embryos of the Desert Tortoise (Gopherus Agassizii) (open access)

Development of Cardiovascular Regulation in Embryos of the Domestic Fowl (Gallus Gallus), with a Partial Comparison to Embryos of the Desert Tortoise (Gopherus Agassizii)

In adult vertebrates, cardiovascular regulation is accomplished by numerous systems with neural, hormonal and local components responsible for the majority of regulation. These regulatory components work in concert to maintain the essential function of blood perfusion to adult tissues. Given the essential nature of this function it is therefore surprising that the development of cardiovascular regulation during gestation is poorly understood. The majority of what is known is based on a single vertebrate model, the fetal lamb. The fetal lamb has been used in multiple studies due to the clear clinical applications and has been pivotal in understanding the onset of regulation in developing vertebrates. However, study on the fetal lamb is limited to the latter 40% of gestation and has the added complication of an in-utero developmental strategy. Therefore the primary focus of this dissertation was to characterize basic cardiovascular regulation in the chicken embryo to provided the needed information for it's use an alternative to the fetal lamb. Developing chicken embryos rely on both alpha and beta adrenergic tones to maintain normal heart rate and arterial blood pressure during incubation. However, on day 21, just prior to hatch, these animals lose both tones on arterial pressure suggesting the …

The Development of IAM District Lodge 776 in Fort Worth, Texas, 1942-1946: A Case Study in the Growth of Organized Labor During World War II (open access)

The Development of IAM District Lodge 776 in Fort Worth, Texas, 1942-1946: A Case Study in the Growth of Organized Labor During World War II

This thesis concentrates on a local union of the International Association of Machinists (IAM), District Lodge 776, of Fort Worth, Texas, during the war years. The main argument of the thesis runs along three basic lines. First, it demonstrates that the experiences of the Fort Worth Machinists clearly fit into the national labor movement during the war years. Second, it argues that the existence, survival, and strength of the union depended greatly on outside forcesan expanding national economy, a powerful national union, and a generally labor-friendly government. Third, it shows that union officers and rank-and-file members used their bases of strengththe national economy, the national IAM, and the federal governmentto build an effective local labor organization.

A Discrimination of Software Implementation Success Criteria (open access)

A Discrimination of Software Implementation Success Criteria

Software implementation projects struggle with the delicate balance of low cost, on-time delivery and quality. The methodologies and processes used to create and maintain a quality software system are expensive to deploy and result in long development cycle-time. However, without their deployment into the software implementation life-cycle, a software system will be undependable, unsuccessful. The purpose of this research is to identify a succinct set of software implementation success criteria and assess the key independent constructs, activities, carried out to ensure a successful implementation project. The research will assess the success of a software implementation project as the dependent construct of interest and use the software process model (methodology) as the independent construct. This field research involved three phases: (1) criteria development, (2) data collection, and (3) testing of hypotheses and discriminant analysis. The first phase resulted in the development of the measurement instruments for the independent and dependent constructs. The measurement instrument for the independent construct was representative of the criteria from highly regarded software implementation process models and methodologies, e.g., ISO9000, Software Engineering Institute's Capability Maturity Model (SEI CMM). The dependent construct was developed from the categories and criteria from the Delone and McLean (1992) MIS List of …

Ecological Enhancement of Timber Growth: Applying Compost to Loblolly Pine Plantations

Access: Use of this item is restricted to the UNT Community
This study explored the application of compost onto a small loblolly pine tree forest in northeast Texas. Its purpose was to determine if the application of various amounts of compost would provide for accelerated rates of growth for the trees. Soil parameters were also monitored. A total of 270 trees were planted and studied in a northeast Texas forest ecosystem. Compost rates of 5, 25, and 50 tons per acre with either soil or compost backfill were utilized and compared to a control without compost. Nonparametric and parametric ANOVA and Chi-Square tests were utilized. The results indicated that greater application rates retained greater moisture and higher pH levels in the soil. Compost applications also yielded a greater survival rate as well as larger tree height and diameter when compared to the control. The 25 ton/acre application backfilled in native soil achieved the greatest average in height and diameter when compared to the averages for the control plot. Greater growth differences for the 25S application can be attributed to additional nutrients coupled with a stable pH consistent with native soil acidity.

The Effect of Increased Collaboration Among the Library Media Specialist and School Personnel on Perceptions of the Roles and Responsibilities of the Library Media Specialist

Access: Use of this item is restricted to the UNT Community
This study measured and explored changes in perceptions of the roles and responsibilities of the library media specialist when the level of collaboration increased. Seven library media specialists targeted four members of their educational communities with whom to increase collaborative activities. Before and after the collaboration began, the library media specialists, the teachers with whom they chose to collaborate, other members from the same educational community, and a control group that did not participate in increased collaboration were given a roles and responsibilities rank-order form. This form was used to measure changes in perceptions regarding the importance of the three roles and selected responsibilities related to the three roles before and after the collaborative experience. The library media specialists and the targeted teachers also kept reflection logs to record factors that enhanced collaboration, factors that inhibited collaboration, and any changes in their teaching style as a result of the collaborative experience. Results indicate that the participating library media specialists themselves experienced the most change. Role identification remains a problem as library media specialists seek to become teaching partners with classroom teachers yet still must keep the library media center aligned with school and district goals and move toward making it …

The Effect of Presence of Support Systems and Level of Agreement on the Performance of Work Groups

In the study of team-based organizations most of the research has focus on the internal make-up and structure of teams. Recently there has been more interest in the effects that environment has on teams. With this new focus Support Systems in organizations have become an area of interest. Examining the perceptions of workers with respect to support systems of organizations could give insight into performance. This study specifically examines the interaction between a team's shared perception of the support in their environment and the level of support in their environment. The interaction between the two does seem to have a strong relationship with perceived performance. How do the two concepts interact, and what does this mean for organizational designers? Both questions are discussed.
