In this study, computer human interaction factors are examined as a possible source of information to aid in the operation and management of local area computer networks. Users' perceptions of computer performance and response time are evaluated in relation to specific modifications in the information organization of a file server in a local area network configuration running in Novell 3.11.

The purpose of this study was to determine the optimal form and timing of feedback to establish a "new" behavior. It examined the relative effectiveness of delivering a corrective feedback immediately before the learner responds to a previously incorrect trial as compared to delivering a corrective feedback immediately after the incorrect response is made. Corrective feedback delivered immediately before the next opportunity to respond produced better learning than corrective feedback delivered immediately after a response. The Feedback Before condition decreased errors during training and increased acquisition rates. Results also indicated an interaction between time of feedback delivery and the complexity of the task. As the task complexity increased, the results were more dramatic in favor of the Feedback Before condition.

The purpose of this study was to explore relationships between and among the degree of mistrust black students hold towards Whites, the students' preferences for race of counselor, and the discussion of problems that are sexual in nature. Participants consisted of 60 black females and 51 black males recruited from a university population. All subjects completed the Terrell and Terrell Cultural Mistrust Inventory, Fischer-Turner Attitudes Toward Seeking Professional Psychological Help Scale, Corrigan and Schmidt Counselor Rating Form - Short Form, Tinsley Expectations About Counseling Inventory, and the Thermometer Method Form developed specifically for this project. A multiple regression model was used to explore the hypotheses of this study. The criterion variables consisted of scores on the Expectations About Counseling Form and Counselor Rating Form. Analyses revealed that the most significant predictors of counseling expectations were race of counselor and participant gender. Black students who were asked to assume \ they would see a black counselor had more favorable expectations about counseling than those black students asked to assume they would see a white counselor. Female participants had more favorable expectations about counseling than male participants. Results also indicated that the most significant predictors of counselor ratings were race of counselor …

Two continuous performance tests were administered to normal adult subjects. The mode of presentation (visual or auditory) and the type of task (vigilance or distractibility) were varied, and their effects on performance measured. Data were collected on eighty-two subjects, and results indicated that auditory presentation of stimuli increased the difficulty of both tasks. Results also suggest that the distractibility task administered in either mode was more difficult than the vigilance task. Intercorrelations among the four continuous performance tasks are provided. Normative data are presented on all four tasks administered. A measure of symptoms of attention-deficit disorder in adults, the Adult Behavior Checklist, was found to correlate significantly with another measure of pathology, the SCL-90-R.

The influence of theoretically prominent family processes on late adolescent college student identity development was the focus of this study. The primary purpose was to test a model of adolescent identity development. This model proposed that family health variables would predict identity development, and that attachment and separation-individuation would each make unique and additive contributions to identity development. The second purpose was to identify instruments which discretely measured the family processes. The third purpose was to better understand family influences by measuring the processes of exploration and commitment. Participants were 150 male and 150 female college students, between the ages of 18 and 23, and from intact families. Questionnaires completed measured family functioning and identity development. Family functioning measures covered three domains (family health, attachment to parents, and separation-individuation) which formed the set of independent variables. The identity measures (ego identity status and identity process) comprised the dependent variables. A hierarchical regression design was employed where family health variables were entered first, followed by attachment variables, then separation-individuation variables. The results indicated mixed support of the model. First, the proposed model was statistically supported for females as all domains predicted identity achievement and diffusion. For males, only family health predicted …

This study sought to determine if different factors had influenced females and males to select engineering/science-related studies at the Texas Academy of Mathematics and Science (TAMS). The data were collected in the fall semester in 1997 at TAMS located on the University of North Texas campus from a survey of factors reported in the literature that had influenced students to enroll in engineering/science-related curriculum.

This study assessed the predictive validity of four independent factors (Rotter Locus of Control Scale, Safety Locus of Control, Organizational Attribution Style Questionnaire, and Rosenburg Self-Esteem Scale) in the establishment of a measure of safety consciousness in predicting on-the-job injuries and the filing of workers' compensation claims. A 125-item questionnaire was designed and administered to assess participants' disposition on each of the four psychological dimensions, demographic data and on-the-job injury information.

The primary research questions dealt with whether parents consider different personality characteristics of importance for boys and girls. Data were collected by conducting a telephone survey of a random sample of parents in the city of Denton with children under the age of eighteen living in the household. Respondents were asked whether they considered the personality characteristics of responsibility, strict obedience, being respectful of the opinions of others, showing good manners, being independent, and having loyalty to a religion not important, somewhat important, or very important for boys and girls. Of the respondents fifty-nine were fathers and one hundred and twenty-one were mothers. The analysis of the data revealed that mothers and fathers have similar attitudes concerning the importance of these personality characteristics.

The purpose of this study was to investigate the effects of four learning styles (accommodator, assimilator, converger, and diverger) and two different presentation methods (traditional and computer-based) on knowledge acquisition in a university classroom.

Previous research suggests that careproviders' attitudes and perceptions significantly influence the type and quality of services received by institutionalized adults with developmental disabilities (IADD). This study explored attitudes careproviders hold concerning training needs of the IADD and their service model orientation. It traced the history of training people with developmental disabilities and provided a brief review of the medical, developmental, and normalization models of service delivery. The conceptual framework upon which this study was based proposed that staff perceptions and orientation concerning service delivery to the IADD can be conceptually related to five factors in a research model. They were identified as: (a) careprovider's characteristics; (b) working environment; (c) previous careprovider experience; (d) developmental disability history within the careprovider's family; and (e) self-reporting of a service delivery orientation. This study examined only a portion of this model (factors a, b, and e). The response sample included 370 professionals and paraprofessionals, aged 17 to 72 years, who were employed at a large residential facility serving individuals with developmental disabilities in Denton, Texas. The respondents were predominantly female (76.5%), Caucasian (72.2%) with slightly less than 75% having more than a high school diploma. The instrument, a self-administered questionnaire, consisted of three parts; …

With the advent of national storm water regulations, municipalities with populations greater than 100,000 are required to obtain National Pollutant Discharge Elimination System Permits (NPDES) for storm water discharges. In addition to the sampling required for the permit process, the City of Fort Worth contracted with the University of North Texas' Institute of Applied Sciences to conduct acute toxicity testing using Pimephales prcmelas and Ceriodaphnia dubia on storm water samples received from the Dallas/Fort Worth Metroplex. A Toxicity Identification Evaluation (TIE) was performed on four samples that exhibited acute toxicity to C. dubia. High levels of metals as well as diazinon were some of the probable toxicants found.
