This thesis discusses Mexican immigration into Texas, and the communities in which the immigrants settled. The focus is on Dallas, with particular emphasis placed upon the women of Little Mexico, a specific barrio there. Sources include interviews with the subjects and their descendants, newspaper articles, journals, unpublished theses about Little Mexico, and books.

Mental imagery is a common theme in research that clarifies how musical thought relates to musical performance. Unfortunately, minimal information exists regarding mental imagery and singers. The purpose of this study was to probe the role, if any, mental imagery plays in the conceptualization of pitch and vowel. By interviewing singers at differing levels of expertise, basic information was obtained about the mental processes used by singers. Through evaluations of the singers' mental processes, it was concluded that 95% of the singers in the study employed mental imagery. All singers described using kinesthetic imagery, while the majority implemented sensory and auditory imagery. Viso-spatial imagery was implemented among the more experienced singers. The majority of singers also reported: imaging pitch and vowel interactively; imaging from an internal perspective; and utilizing mental rehearsal. Less than half of the singers described using methods other than mental imagery to conceptualize pitch and vowel.

This thesis estimates the spatial extent of chlorinated solvent contamination of the soil at the Naval Air Station, Dallas, then estimates the fate and transport of these contaminants, over time, using the Soil Transport and Fate database and the Vadose-Zone Interactive Processes (VIP) modeling software. Geostatistical analysis identifies two areas with serious chlorinated solvent contamination. Fate and transport modeling estimates that this contamination will degrade and disperse from the soil phase to below regulatory limits within one year, although there is a risk of groundwater contamination. Contaminants are estimated to persist in the water and air phases of the soil. Further sampling is recommended to confirm the results of this study.

Areas were sampled in the White Rock Creek Watershed to examine sediment bound trace metal distributions and sorption relationships. A Kruskal-Wallis AOV found significant among area differences for most metals, and SNK-like multiple comparisons were used to group these areas. Kruskal-Wallis AOVs similarly found among area differences for sediment components that bind trace metals (Fe and Mn oxides and organic carbon) and physicochemical conditions that influence metal sorption (particle size and pH). Multiple correlation found numerous relationships among trace metals, sediment components, and physicochemical conditions. Statistical relationships indicate that metal partitioning to various sorption factors is metal specific. White Rock Creek Watershed trace metal concentrations are comparable to those in many urban watersheds.

This study examines the relationship between exercise adherence and several factors: self-motivation; attitudinal commitment; predisposing, enabling, and reinforcing (PER) factors; and barriers related to exercise. The sample (N=431) consists of employees at Texas Instruments, Incorporated in Dallas, Texas. The sample was placed into six comparison groups: high adherers, low adherers, nonparticipants who exercise, nonparticipants who do not exercise, dropouts who exercise and dropouts who do not exercise. Using a one-way ANOVA, the results show significance (p<.01) among the groups for: self-motivation and barriers. Attitudinal commitment and PER factors did not show significance. The results can be applied to worksite health programs to increase exercise adherence among employee populations.

This purpose of this study was to investigate and examine the attitudes of therapists who treat HIV-positive (HIV+) clients. Specifically, therapists' perceptions of their own preparedness in dealing with specific issues and emotions of HIV+ clients were examined. Also, therapists' evaluation of their own efficacy of specific therapeutic approaches with HIV+ clients was examined. These therapists' perceptions and evaluations of all their clients in general were compared to their HIV+ clients. Comparisons were also made within the two groups.

The relationship between work-family role strain and parenting styles (permissive, authoritarian, and authoritative) was examined. Questionnaires were completed by 45 mothers whose children (ages newborn to three years) were enrolled in early childhood centers in the Dallas-Fort Worth-Denton, Texas, area. Participants were primarily Caucasian, high-income mothers who had attended college. Results indicated no significant relationship between role strain and parenting styles. Open-ended questions revealed insights into mothers' reported role strain. This research may provide employers and professionals who work with families with information to assist mothers in reducing role strain. They may also recognize that parenting style may be independent of a successful balance of work and family.

In an attempt to determine the effectiveness of a pretreatment assessment procedure known as the scatter plot (Touchette, MacDonald, & Langer, 1985), direct observational data was collected by 13 middle school teachers on four "problem" students. After four weeks of data collection, interobserver agreement probes were calculated and a visual analysis of the plotted data was performed to ascertain a possible pattern of problem behavior. Additionally, in an attempt to assess the teachers' perceptions of the scatter plot, the 13 teachers were asked to complete a questionnaire. Although a visual analysis of the plotted data suggested a possible pattern of problem behavior, interobserver agreement probes failed to achieve a desired overall reliability of 90% or higher. Despite a low IOA, results of the questionnaire administered to the 13 teachers generally supported the use of the scatter plot as a means of assessing student behavior. Possible reasons for failing to attain an IOA of 90% or higher include the total number of students in a class, the number of subjects observed per period, the teacher's location in the classroom, and the subjects ability to recognize if the teacher was "looking." Recommendations are provided regarding future research concerning the scatter plot and …

This study investigated relationships among and between psychological hardiness, coping style, and burnout in 101 female hospital nurses. The third generation (50-item) hardiness scale, scored by the revised scoring procedure, was used to measure hardiness and its components. The Maslach Burnout Inventory was used as the measurement for burnout. Coping style was assessed by the COPE Inventory. The components of hardiness, commitment, control, and challenge, were hypothesized to be negative predictors of emotional exhaustion and depersonalization and positive predictors of personal accomplishment. In addition, hardiness and its components were postulated to be positively related to adaptive coping styles and negatively related to maladaptive coping styles. Emotional exhaustion and depersonalization were thought to be related positively to maladaptive coping styles and negatively related to adaptive coping styles. Personal accomplishment was thought to be positively related to adaptive coping style and negatively related to maladaptive coping style. Simple and multiple regressions were used.

The problem of this study involved identifying and ranking perceptions of the attributes of exemplary teaching of adjunct faculty of the Dallas County Community College District. Data was collected by a 75 item opinionnaire and a demographic data sheet which was sent to a population of 3,000 employees of the Dallas County Community College District and 100 exemplary faculty from 39 of the 50 United States. The five chapters were titled Introduction, Review of Literature, Methods, Presentation and Analysis of Findings, and Summary, Discussion, Conclusions, and Recommendations. Revealed through the findings of Chapter 4 was the order of attributes as a Grand grand rank found through the combining of the grand rank order of the Dallas County Community Colleges' employees and the rank order of the nationally recognized exemplary faculty. Findings disclosed that a rank ordering of items represented by Kendall's W at .9654 with a chi-square of 142.8815 at the .001 level of significance. These findings led to the rejection of three null hypotheses and the following related conclusions: (1) perceptions of importance of teaching attributes, can be rank ordered, (2) while a high level of significant values of W may be interpreted as meaning that the observers and …

Although much research has examined the impact of life stress and the subsequent development of health symptoms, most of this research has been done with White middle class adults. Similar to the adult research, life stress research with children and adolescents has focused on White middle class individuals. The present study expands the knowledge about the stress process in ethnic/racial adolescents while controlling for the effects of SES. A sample population consisting of 103 Black students, 129 Hispanic students, and 105 White students was compared with respect to stressful events experienced, coping strategies, and social support. Students from a wide range of socioeconomic backgrounds were included within each ethnic/racial group studied. After experimentally and statistically controlling for the effects of socioeconomic status, significant differences were observed. Black and Hispanic students reported receiving higher levels of Enacted Social Support (actual support) than White students. Contrary to what has been previous suggested, Black and Hispanic students reported having experienced fewer stressful life events than White students. Other ethnic/racial group differences that emerged included differences in ways in which specific patterns of moderator variables served to enhance the relationship between life stress and psychological symptomatology.

Stoney Burns (Brent LaSalle Stein) edited and published Dallas Notes, a Dallas, Texas, underground newspaper, from November 1967 through September 1970. This thesis considers whether Burns was the unifying figure in the Dallas counterculture.

Ninety-nine African-American undergraduates, at a historically Black college, completed the African American Acculturation Scale to compare fraternity/sorority members with independents' participation in Black cultural traditions versus dominant White society. Greek members were hypothesized to be more traditional, because these organizations represent ethnic enclaves, have duplicate institutions, and communicate ethnic socialization; findings did not support this, but reasons for joining did. They were more superstitious in their beliefs than nonmembers, likely related to pledgeship and initiation rituals. Validity data on the new measure were provided. Why participants join fraternities, why they like/dislike them, and what purposes they serve was also examined.

This was a quantitative study designed to determine the role orientation and role behavior of school resource officers in public secondary schools in a metropolitan area of central Texas. The perception of role orientation and role behavior was assessed by two relevant groups: secondary school principals and school resource officers. Each group's perception of role orientation and role behavior was compared to determine if role conflict was an inhibiting factor in the job performance of the recently created school resource officer position. This instrument relied heavily on the work of James Telb who conducted a 1982 study involving the role perceptions of public safety officers in public institutions of higher learning as viewed by senior patrol officers and campus judicial officers. A questionnaire was distributed to both groups to assess perceptions of role orientation of school resource officers as either service oriented or law enforcement oriented. A statistically significant difference in role orientation was identified between groups on two factors: maintenance of traditional police values and police discretionary powers and handling of behavioral scenarios.

Proprietary colleges are uniquely different from two or four year colleges due to the emphasis on the student establishing a definite career path prior to enrollment. Because of this career track emphasis, Bandura's (1977) postulation that self-efficacy is a significant variable influencing task completion may offer insight into the challenge of student retention at a proprietary college. The study's purpose was to determine if career self-efficacy, demographic factors, and academic preparedness measures in first quarter students could predict student persistence, class attendance, and academic performance. The statistical technique of multinomial logistic regression was applied to data files of 725 first quarter students who attended The Art Institute of Dallas from Summer 1996 through Winter 1997. The predictor variables included a measure of career self-efficacy, ASSET scores (American College Testing Program, 1994), ethnicity, age, gender, full-time/part-time attendance, high school grade point average, parents' educational level, socioeconomic status, and developmental course placement. Criterion variables were completion, class attendance, and cumulative grade point average.

The present study compared the academic stress levels of 450 college sophomore students at a public university and a public two-year college. This investigation also explored the levels of academic stress by institutional type, age, gender, and ethnicity. Data were obtained from having the subjects complete the Academic Stress Scale, a questionnaire which lists thirty five stress items found in the college classroom. Analysis of variance and t-tests were used to analyze the data. There were 225 subjects each in the community college group and the university group. The university group had a statistically significant higher mean stress score than the community college group. 294 traditional age (23 and younger) and 156 nontraditional age (24 and over) subjects stress levels were compared. It was found that the traditional age college student group experienced a statistically significant higher academic stress level in both academic settings. Group means were compared between the stress scores of 245 female and 205 male subjects. At both the community college and university levels, the female group had a statistically significant higher level of academic stress. The academic stress levels were also compared according to ethnicity. The minority group consisted of 104 subjects and 346 subjects comprised …

The purpose of this study was to provide both businesses and institutions of higher education with a descriptive analysis of the programs of five companies that have utilized community colleges in their basic skills programs. The five companies represented included Texas Instruments Defense Systems Corporation and SGS-Thomson Microelectronics (electronics companies), Abbott Laboratories (a pharmaceutical company), J & E Die Casting (a small die casting firm), and Company X, a semiconductor company that requested anonymity. The community colleges included were Richland College, Brookhaven College, and North Lake College. Modified case studies were used to obtain data collected through individual interviews with representatives from the community colleges and the companies. The syntheses of documentaries provided details of how the five community college-directed workplace literacy programs met, or failed to meet, their literacy challenges. Descriptions of the curriculum and structure of each program were also included. Numerous factors contributed to the success or demise of the programs studied. Elements that served as powerful assets when adequately supported were detrimental when neglected. Factors common to all of the programs were financial support, management philosophical support, confidentiality, adequate testing instruments, class schedule flexibility, instructor capability, physical classroom facilities, and work-related documentation integrated into the curriculum. …

The purpose of this study was to assess the effectiveness of computer-assisted instruction (CAI) as a method of delivery. Student attitude toward method of instruction was examined. Additionally, the amount of study time required by the students was observed.

The present investigation evaluated sport-related motivational climates by assessing personal and perceived parental goal orientations and perceived parental pressure in children and adolescents. Data were collected from 202 middle-class, racially diverse students, including 43 male and 50 female children aged 12 or below (M age = 10.6) and 51 male and 58 female adolescents aged 13 or above (M age = 14.7), who had participated in a variety of organized sports, and were enrolled in elementary, middle, and high schools of the Dallas (TX) Independent School District. Measures included personal and parental projected versions (mother's and father's) of the Task and Ego Orientation in Sport Questionnaire (TEOSQ), the Sport Parental Pressure Scale (mother's and father's versions), and a background assessment.

Student retention is one of the most important issues facing higher education. The demand for accountability of higher education has pushed the issue of student retention to the forefront of its agenda. Increasingly, state legislatures are tying funding to institutional effectiveness, using graduation rates as measures of academic quality. Though there is an abundance of literature of studies conducted at the four year institution, few studies have examined the community college student. This study attempted to identify 4 specific pre-enrollment variables, (1) parent's education, (2) high school senior grade point average, (3) educational goals and (4) racial origin, as predictors of persistence and retention. The sample included 312 entering freshmen at North Lake College in Irving, Texas who were administered the College Student Inventory (CSI) in the fall semesters of 1995 and 1996. The 1995 cohort consisted of 201 entries, 103 (51.2%) female and 98 (48.8) male. The 1996 cohort consisted of 111 entries, 65 (58.5%) female and 46 (41.5%) male. A data base was constructed by extracting selected data elements from the completed inventory. Each student was tracked for one year following the semester they completed the survey. The Pearson Chi-Square Test of Independence with .05 level of significance …

Reorganization efforts within colleges and universities are increasingly considered as institutions look for ways to streamline operations for financial cost savings or competitive advantage. The purpose of this study was to assess a particular change effort in a university library which took place between August, 1996 and July, 1997. A team was formed to manage the change effort, and an outside consultant was hired to facilitate the process and guide the team. Stufflebeam's evaluation model was used as a conceptual framework to evaluate the entire process which included a particular change management model brought in by the consultant. The entire change effort was described by the author as a participating member of the team and assessed by gathering feedback from team members, library staff members affected by the effort, and members of the library administration.

The research was designed to test the hypothesis that significant differences exist between Hispanic and non-Hispanic students respecting background characteristics and reasons for enrollment in selected two-year colleges. The findings led to firm conclusions regarding the need for educational institutions to provide remedial and tutorial services, liberal financial aid, culturally sensitive institutional ambience, diversity in faculty, counselors, and staff, and instructional and student development programs responsive to the cultural diversity of all students.

The purpose of this study is to examine domestic violence as it occurs in same-sex male relationships. Data were collected by in-depth interviews with twenty-five gay males, who were between the ages of 23 and 43, and who had previous experience being in a homosexual relationship where domestic violence was present. The major findings of this study include the respondents': 1) definitions of domestic violence and abuse; 2) the type of domestic violence or abuse personally experienced; and 3) reasons they believe domestic violence or abuse occurs in these types of relationships. This study illustrates the need for further research in this area of domestic violence and for programs or services targeted for this specific population.
