The City of Denton Pecan Creek Wastewater Treatment Facility has periodically failed effluent toxicity testing. A Toxicity Identification Evaluation has determined that Diazinon in the effluent is contributing to the observed toxicity. Chlorpyrifos is also implicated as a factor. The City of Denton constructed a half acre experimental wetland to remove Diazinon related toxicity. Results from spiking and microcosm experiments indicate that the wetland can reduce the Diazinon.

The purpose of this study was to re-examine the issue of whether adult children of alcoholics experience more depression, anxiety, and lower self-esteem than do children of non-alcoholic families. This study is a replication of the study of David Dodd, entitled A Comparison of Adult Children of Alcoholic Families with Adult Children from Non-Alcoholic Families. 1990. The measures used in this study were as follows: Children of Alcoholics Screening Test, the Beck Depression Inventory, the State-Trait Anxiety Inventory, the Coopersmith Adult Self-Esteem Inventory, and a questionnaire developed by this writer designed to obtain family history regarding not only alcoholism, but other issues of family dysfunctionality as well. The subjects for this study were 231 students enrolled in the counselor education program at this university, all aged 19 or older. Of the 230 subjects, 31 were male and 199 were female. Eleven males identified themselves as children of alcoholics, as measured by the Children of Alcoholics Screening Test, and 60 females identified themselves as children of alcoholics. Thus, a total of 71 subjects in this study were identified as children of alcoholics. T-tests were conducted to see whether any differences existed between the male and female groups. No significant differences were …

This study was designed to determine the effects of child-centered play therapy as a play therapy training model for beginning play therapy students. The purpose of this study was to determine the effects of child-centered play therapy training on play therapy trainees in (a) improving positive attitudes and beliefs toward children; (b) improving knowledge of child-centered play therapy; (c) improving confidence in applying child-centered play therapy skills; (d) reducing dominance tendencies in trainees' personality as measured by the California Psychological Inventory; and (e) increasing tolerance levels in trainees' personality as measured by the CPI. The experimental group, consisting of 37 counseling graduate students with a specialty in child counseling, received 45 clock hours of introduction to play therapy graduate course training at the University of North Texas, Denton. The control group, consisting of 29 counseling graduate students with a specialty in child counseling, received other counseling graduate courses training but no play therapy training at the time of their participation in this study at the University of North Texas. Both experimental and control group students completed the pretest and the posttest on the Play Therapy Attitude Knowledge Skills Survey and the California Psychological Inventory at the beginning and the end …

This thesis examined student-participants' self-reported use of romantic relational maintenance strategies and their partners' reports of relational satisfaction. Additionally, individuals outside the romantic relationship reported on student-participants' general communicator style. The research proposed that general style reports would be predictive of relational maintenance strategy usage and of romantic partners' relational satisfaction. The study found that general style behaviors may not be indicative of relational maintenance strategy usage or romantic partners' relational satisfaction. Tests of sex differences revealed that females' expression of various relational maintenance strategies and style behaviors are associated with male partners' relational satisfaction; however, no results were obtained indicating specific behaviors expressed by males result in female partners' relational satisfaction.

In this study, a computer simulation model for library CD-ROM LAN systems was created. Using this model, the system optimization problems were examined. The simulation model imitated the process of the actual decision variables changing their values and generated the corresponding results. Under a certain system environment, if the values of decision variables are changing, the system performances are getting changed also. This study investigated these relationships with the created model. The system users' interarrival time, service time, and other relevant data were collected on randomly selected days in a university library. For data collection, both of the observation and the system automatic metering software were used. According to the collected data, a discrete events simulation model was created with GPSS/H. The simulation model was proven valid and accurate by a pilot test and by the calculation with queuing theory. Statistical tests were used for data comparison and analysis. In addition, animation technique was used to show the simulation process by using Proof Animation. By this technique, the simulation process was monitored on the screen.

This study investigated the effects of personality characteristics on emergent leadership in small group settings. Two instruments were used to assess personality factors: The BASIS-A and the California Personality Inventory (CPI). A sociometric tool was developed to elicit leader ranking of female group members. The BASIS-A, was used to test for Taking Charge and Wanting Recognition lifestyles in women who emerged as leaders. The CPI was used to assess female emergent leaders for Dominance and Leadership Potential. The two instruments and a sociometric form were distributed to 115 female graduate counselor-in-training students the last week of their group counseling experience. This survey resulted in 55 respondents (N=55) from eleven discussion groups. It was expected that women who had the highest averaged leader rank would demonstrate higher test scores in Dominance, Leadership Potential, Taking Charge, and Wanting Recognition than women who received a lower averaged leader rank. It was also thought that these four test factors would be highly related. If so, a case would be made to use the BASIS-A as an emergent leader assessment tool because it is consistently based in one psychological theory. No significant effect was found between the highest leader rank and three of the test …

The purpose of the study is to examine adult attachment relationships among a group of college students and their parents. Two attachment hypotheses were tested: The mental model hypothesis for attachments with parents and romantic partners and the compensation hypothesis for attachment with God. Hypothesis 1 attempted to determine if there was agreement between parents and children about a self-reported attachment style. Support was found as students and parents had a significantly higher level of agreement when reporting a secure style of attachment between them, with sons being significantly highest. Hypothesis 2 examined agreement on attachment style between generations: Children's report of attachments to parents and parents' report of attachment to their parents. Results indicated that parents' reporting a secure style of attachment to their parents was significantly higher with their same gender parents. Hypothesis 3 produced two 15 x 15 correlation matrices including measures of romantic attachment and religiousness for children and parents. In general, further validity for measures used is provided in numerous expected correlations. Anxious and avoidant romantic attachment styles and desperate love were significantly positively related and were often negatively related to a secure style of attachment. Results indicate significant relationships between fathers' and children's (particularly …

According to Alfred Adler, founder of Individual Psychology, a feeling of inferiority is in some degree common to all people. People who are unable to overcome these inferiority feelings by striving for cooperation may become discouraged. Although there are three scales to measure social interest, no scales measuring discouragement for adults was found. Additionally, Adler held basic assumptions regarding homosexuality, and the findings suggest that the assumptions should be reexamined. The purpose of this study was twofold. First, three University of North Texas candidates developed a discouragement scale for adults 18 years of age and older, known as the Discouragement Scale for Adults (DSA). Discouragement was examined relative to the five life tasks. Second, this candidate normed the instrument for the scores of gay male subjects and compared it to the scores of the other subject groups. Since the emphasis was on developing the instrument and norming it for various subject groups, no hypothesis was developed. Data was collected on three subject groups, known as the general norm subjects, the discouraged subjects, and the gay male subjects. Analyses were performed on the scores. Among the analyses, it was found that gay male subjects were slightly more discouraged than the general …

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 …

The objective of the present study was to evaluate the relationship between a set of cofactors and severity of cognitive impairment, to determine if there were any factors which significantly predicted more severe neurocognitive deficits in persons with AIDS. Twenty-four male volunteers recruited from community groups and physician referrals participated. Subjects completed several self-report questionnaires eliciting information regarding demographics and risk factor variables, in addition to a comprehensive battery of neuropsychological tests. A severity of cognitive impairment summary score was computed for each subject, reflecting both the number of impaired tests and their distance in the impaired direction from normative data. Neither CD4 count, number of months since diagnosis of AIDS, number of AIDS-related illnesses, number of recent stressors, history of head injury/LOC, history of substance use, current or past psychiatric disorder, history of learning disability nor history of other medical illness were found to be significantly related to severity of cognitive impairment in this sample, after controlling for the effects of age, level of education, estimated premorbid IQ and mood status. However, no reliable conclusions could be drawn from this study because the small sample size resulted in an unacceptably low level of statistical power for the desired regression …

The purpose of this study was to examine the social perceptions of young children with disabilities and young children of color. Further, an attempt was made to determine whether differential rates of acceptance were experienced by either group, or by the group of children who were of color and also had a disability within integrated classrooms. Young children (age 5.0 through 6.11) were studied in intact groups (N=120) from child care centers in the Texas counties of Denton and Dallas. Three measures of social perceptions were implemented: (a) a forced choice (multiple alternative) technique using dolls of a variety of ethnicities and ability statuses in which children must select dolls they feel represent a list of positive and negative attributes; (b) social distance theory as measured by children's artwork; (c) a sociometric rating. The results of this study showed significant areas (p< 05) of stereotype and bias in the perceptions of young children toward ethnicity, disability and gender. Implications for further research into the efficacy of multicultural and anti-bias education programs is recommended.

A sample of 227 undergraduate students was administered pre-intervention paper-and-pencil questionnaires to assess homophobia, fear of AIDS contagion, symbolic representations of AIDS and homosexuality, and specific personality attributes including authoritarianism, religiosity, and conservatism. Participants then read one of eight intervention vignettes about an ill person; these vignettes varied by sexual orientation of the patient, disease (AIDS versus lung cancer), and mode of transmission (in the AIDS conditions). Participants then completed post-intervention measures assessing the degree to which the ill person in the vignette was responsible and to blame for his illness, the level of stigma toward him, and concerns about social interactions with him. Results indicate the following: a) Attributions of personal responsibility are primarily a function of mode of illness transmission; b) fear of AIDS contagion is predictive of stigma and social avoidance of PWAs; and c) AIDS-related stigma and attributions of blame are largely a function of symbolic associations between homosexuality and IV drug abuse (which were previously stigmatized) and AIDS.
