Considering the explanations of schizophrenia that presume schizophrenia spectrum disorders (e.g., schizotypal personality disorder, schizoaffective disorder, etc.) to be genetically related to schizophrenia, the purpose of this study was to investigate the attention and information processing abilities of individuals who have been identified as schizotypal or psychosis-prone (i.e., schizophrenia spectrum functioning in individuals who do not have schizophrenia). Research indicates that persons identified as psychosis-prone may show attention and information processing deficits similar to individuals with schizophrenia. The identification and description of individuals who later decompensate into schizophrenia would advance the understanding of schizophrenia and its causes. The Chapman's PER-MAG scale (Perceptual Aberration-Magical Ideation) was used to identify 35 hypothetically psychosis-prone college students (schizotypy group) and 42 normal college students (nonschizotypy group) out of the 806 volunteer subjects. Their attention and information processing abilities were measured by COGLAB (a multiparadigmatic cognitive test battery that represents a continuum of cognitive functions, from preattentional to attentional, to conceptual). Their social adjustment was measured by the Premorbid Adjustment Scale (PAS). The hypotheses of the study were that the hypothetically psychosis-prone subjects would perform poorer than controls on COGLAB measures and that COGLAB measures of a more molar nature would better predict social adjustment …

Although several studies question information technology's contribution to productivity, organizations continue to invest in client/server systems (CSSs) particularly as enablers of business process reengineering (BPR). These efforts may be wasted if they do not improve business processes. This study focused on business processes and investigated the role of workstation-based CSSs in changing business processes. A multiple case study of workstation-based CSS databases in three organizations was performed with the proposition that they moderate the relation between managerial action and changes within business processes. The research framework suggested that changes to business processes are achieved by reducing uncertainty. In order to measure change in business processes, this study categorized business process change into: (1) compressing sequential tasks across functions, (2) compressing tasks vertically within the managerial hierarchy, (3) eliminating slack resources, (4) reducing the distance between the point of decision and the point of information or eliminating intermediaries, (5) reconfiguring sequential processes to operate in parallel, and (6) linking parallel activities during the process. Data collected from questionnaires, interviews, and observations from three case studies were used to construct network diagrams, relationship matrices, reachability matrices, and task tables of business processes. The results of this research partially support the proposition that …

Several studies have suggested that the effect of cultural differences among Information Systems (IS) professionals from different nations on the development and implementation of IS could be important. However, IS research has generally not considered culture when investigating the process of systems development. This study examined the relationship between the cultural backgrounds of IS designers and their process-related values with a field survey in Singapore, Taiwan, the United Kingdom and the United States. Hofstede's (1980) value survey module (i.e., Power Distance (PDI), Uncertainty Avoidance (UAI), InDiVidualism (IDV) and MASculininity/femininity) and Kumar's (1984) process-related values (i.e., technical, economic, and socio-political) were utilized in the data collection. The hypotheses tested were: whether the IS professionals differed on (H.,) their cultural dimensions based on country of origin, (Hg) their process-related values based on country of origin, and (H3) whether a relationship between their cultural dimensions and their process-related values existed. The countries were significantly different on their PDI, UAI and MAS, but not on their IDV. They significantly differed on their technical and sociopolitical values but not on their economic values. IDV and MAS significantly correlated with the process-related values in Singapore, Taiwan and the United States. In the United Kingdom, UAI significantly …

This dissertation describes the various military outposts on the Texas frontier between 1866 and 1886. It is arranged geographically, with each chapter covering a major fort or geographical area and the smaller posts associated with it. Official military records and government reports serve as the primary sources of data. In 1866 when the United States Army returned to the defense of Texas after four years of civil war, the state's frontier lay open to depredations from several Indian tribes and from lawless elements in Mexico. The army responded to those attacks by establishing several lines of major forts to protect the various danger areas of the frontier. To extend its control and protection to remote, vulnerable, or strategically important points within its jurisdiction, each major fort established outposts. Two main categories of outposts existed in Texas, subposts and picket stations. Subposts served as permanent scouting camps or guarded strategic points or lines of communication. Picket stations protected outlying locations, such as stage stations, that were particularly vulnerable to attack. Because Indians raiding in Texas usually operated in fairly small groups, garrisons at outposts were similarly small. Company-sized detachments generally garrisoned subposts, and picket stations seldom held more than a dozen …

The purpose of this study is to examine the four basic student assistance models and determine their distribution in Texas, describe the student assistance programs in place in public school districts in Texas including the program's goals, objectives and components, and explore the perceived effectiveness of student assistance programs as a viable means of drug and alcohol education for students enrolled in public school districts in Texas in kindergarten through twelfth grade.

Review of previous research on cultural differences in pain experience and/or pain behavior revealed that cultural affiliation affects pain perception and response. Unfortunately, the many inconsistent findings in the literature on cultural differences in pain experience and behavior have made interpretations and comparisons of results problematic. These inconsistent findings could be attributed to variations in acculturation level among cultural groups. The purpose of this study was to investigate cultural differences in pain experience (assessed by McGill Pain Questionnaire, the Box Scale, the Headache Pain Drawing, and the Headache Questionnaire) and pain behavior (measured by determining medication use and interference of daily functioning due to headaches) among Mexican (n = 43), Mexican American (n = 36), and Anglo American (n = 50) female chronic headache pain sufferers. The contribution of acculturation to differences in pain experience and behavior among cultural groups was measured by the Acculturation Rating Scale for Mexican Americans. The three cultural groups of women significantly differed on pain experience and pain behavior. Specifically, Mexican women experienced their headache pain more intensely, severely, and emotionally than Mexican American and Anglo American women. Furthermore, Mexican women were more willing to verbally express their pain than the other two groups. As …

The percentage of women who receive doctorates has increased by over 300 percent during the past three decades. The consequences of pursuing the Ph.D. degree have always been far reaching and profound, serving as an impetus and springboard for the reconfiguration of one's beliefs, values, and professional life. The purposes of this national study were to ascertain and describe marital and social changes that occurred in the lives of women who were awarded the Ph.D. degree at midlife. A questionnaire was distributed to a sample of three-hundred women who hold the Ph.D. degree and were employed in institutions of higher education in the United States. The study sought to identify the effects of the Ph.D. experience upon the marital relationships, friendships, and social activities of women who completed the degree between the ages of thirty-five and forty-five. Demographic data were collected which were related to their marital status before, during, and after the Ph.D. experience. Both closed and open-ended questions were posed which solicited information pertaining to their post Ph.D. experience. This research reports both quantitative and qualitative findings. The majority of women who complete the Ph.D. experience at midlife undergo and initiate changes in their lives which impact their …

The purpose of this study was to determine the effectiveness of career group counseling in raising the self-concept of at-risk high school students. The following subgroups were represented in the sample: male and female students, white and non-white ethnic groups, and students from sophomore, junior, and senior classifications. Two groups of students in the Lewisville Independent School District meeting the criteria for at-risk as defined by House Bill 1010 were administered a pretest and posttest using the Piers-Harris Children's Self-Concept Scale. The experimental group was from the Lewisville Learning Center. The control group was students enrolled in the Coordinated Vocational Academic Education (CVAE) classes at Lewisville High School. A treatment sample of 25 students received career group counseling. A nontreatment sample of 25 students did not receive any group counseling. The t-test for independent samples was used to analyze the data. The pretests for the experimental and control groups showed no significant difference at the .05 level. The treatment sample received 30 hours of group counseling in the Fall semester of 1994. At the end of 30 hours of counseling a posttest was administered to the treatment sample and to the control sample. The t-test for independent samples was used …

Under investigation in this study was the effect of ASE certification of automotive technician training programs and other selected factors on ASE test outcome and job placement rate. This research ponders whether the time and money invested in certifying technician training programs is returning desired improvements in this automobile manufacturer's dealer service staff. The study focussed on technicians employed at Chrysler dealerships around the United States. The 2 samples totalling 387 males between the ages of 22 and 30 were drawn from 1,007 graduates of automotive technician training programs. Technicians that completed a formal training program beyond the high school level certified by the National Institute for Automotive Service Excellence (ASE) were compared to others whose training was not certified by ASE. Comparisons were made on the basis of ASE Automobile Technician Test scores and on the length of time from training program completion to employment. This research sought to identify the significance of association between three main predictors - the status of training program ASE certification, work experience and year of training program completion - and the most desirable levels of ASE test outcome (at or above 90% on the ASE test) and job placement rate (immediately following completion …

The purpose of the study was to determine whether students' timbre preferences in the sixth grade remain stable through the tenth grade. The investigation also examined whether gender, band instruction, or musical home environment makes any difference in influencing the stability of students' timbre preferences from grade six through ten. Students' timbre preferences at the beginning of the study were compared to their preferences four years later. The students' timbre preferences were obtained by employing Gordon's Instrument Timbre Preference Test (ITPT). A questionnaire was also utilized at the conclusion of the study to determine which students had musical home environments and which did not. All sixth grade students enrolled in a single school district took the ITPT. Each student's scores were tallied and ranked in order to determine their timbre preferences; four years later they were retested and their scores were ranked again.

In a rapidly changing environment of growing competition for limited resources and ever increasing operational costs, institutions of higher education must focus on all aspects of the organizational functions to insure institutional effectiveness and the maximization of student success. This study will use a Student Environment Model (SEM) to assess students' perception of their college environment outside of the formal classroom at a unique two year technical college. The information obtained is used by the administration of Texas State Technical College Waco (TSTCW) to make appropriate adjustments in programs, services, or policies when the student data indicates that change or improvement is needed. While the SEM provides an indication of the students' "image" of the college environment, it can also provide indicators of areas which need improvement or require change. Applying the SEM information to decision making, problem solving, and planning will allow the institution and its people to move toward higher productivity and continuous quality improvement.

This quasi-experimental study examined the effects of participation in a Supplemental Instruction (SI) program on student test performance in a second-level developmental mathematics class in a four-year university setting. This research deviated from past research on Supplemental Instruction in that it examined effects of the program at the end of each test block rather than at the end of the course only. The quasi-experimental design was precipitated by an inability to control factors of participation and limited sample size. Test data were analyzed using analysis of variance; final course grades were analyzed using chi-square.

The major purpose of this study is to analyze hazardous waste enforcement by the states as mandated by the Resource Conservation and Recovery Act of 1976 (RCRA). States' historical enforcement records from 1980 to 1990 are analyzed to determine the pattern of variations in enforcement. This study differs from previous studies on hazardous waste regulation in that it employs longitudinal data from 1980 to 1990 to analyze states' enforcement effort.

George Walker, pianist, composer and pedagogue, composed piano sonatas in 1953, 1957, 1975, and 1984. The Sonata No. 4 demonstrates the composer's continued fascination with a relaxation of traditional forms, coloristic effects of persistent interval combinations, incorporation of folk elements into his thematic material, and harmonic and rhythmic underpinnings as structural bases to his work.

This study describes the development of the black business and professional community with emphasis on the period from 1920 to 1930, the riot itself, and the impact of the episode on the local black community. It utilizes traditional historical research methods, county records, contemporary newspapers, and oral history.

The objective of this research was to describe the extent to which Gift Annuity Agreements were used by United States higher education institutions in raising private philanthropic support during the period 1988-93.

The purpose of this study was to examine how parental separation is related to eating disturbances and assertiveness in females who struggle with bulimic symptoms. Two-hundred ninety-two undergraduate females from the University of North Texas comprised the subject group. Using pen and paper measures of assertiveness, bulimia, and parental separation, support was found for the prediction that there would be a relationship between assertiveness and parental separation. Likewise, partial support was found for the prediction that there would be a relationship between bulimia and parental separation. Parental separation was found to affect levels of bulimia and assertiveness. Finally, it was found that subjects endorsed greater emotional independence from fathers than from mothers.

Using a survey and case study formats, this study focused on the level of understanding and implementation of Title IX relating to Texas public school students. The survey focused on the degrees of principal understanding and the compliance with the statute. Additional areas of study analyzed the impact of such factors as principal gender and school level on understanding and implementation. The case study examined the degrees of implementation for a district that had experienced civil rights action and one that had not.

Female teenagers have been found to be the most affluent teens according to the Rand Youth Poll's nationwide survey. The survey finds the average weekly income from female teens age 16 to 19 to be $82, with $50 from earnings and the balance from their allowances. Other findings from the survey indicate that adolescent girls receive more than adolescent males in allowance from parents, as mothers understand the need for the female teen to have the income necessary to purchase clothing and cosmetics. Past research studies have attempted to measure the influence sources on teenagers when purchasing clothing by asking teens to rank different influence sources or by asking the teens who accompany them when shopping. The current research study develops a structural equation model that allows for the comparison of the three predominant influence sources identified in the consumer socialization literature, i.e., parental influence, peer influence, and promotional communications sought out by the teen. To test the model, 206 randomly selected female teenagers completed a mail questionnaire regarding the influences on clothing interest. The female teens were all members of a non-denominational youth group, age 13 to 19, living in the North Texas region. The model derived is only …

This study was designed to determine the effectiveness of filial therapy with incarcerated mothers as a method of increasing empathic behaviors with their children, increasing attitudes of acceptance toward their children, and reducing stress related to parenting. Filial therapy, a method of training parents to respond and interact therapeutically with their children, focuses on enhancing the parent-child relationship. The sample population of 22 volunteer subjects was drawn from a pool of incarcerated mothers in the Denton County Jail who had children between three and ten years of age. The experimental group parents, consisting of 12 incarcerated mothers, received 2-hour filial therapy training sessions biweekly for five weeks and participated in biweekly 30-minute play sessions with one of their children. The control group parents, consisting of 10 incarcerated mothers, received no treatment during the five weeks. The three written self-report instruments completed for pretesting and posttesting purposes by both groups were The Porter Parental Acceptance Scale, The Parenting Stress Index, and The Filial Problem Checklist. The parents were also videotaped in play sessions with their child before and after training as a means of measuring change in empathic behavior. Analysis of Covariance revealed that incarcerated mothers in the experimental group had …

During the Korean War, US-Japan relations changed dramatically from the occupation status into one of a security partnership in Asia. When North Korea invaded South Korea, Washington perceived Japan as the ultimate target. Washington immediately intervened in the Korean peninsula to protect the South on behalf of Japanese security. Japanese security was the most important objective of American policy regarding the Korean War, a reality to which historians have not given legitimate attention. While fighting in Korea, Washington decided to conclude an early peace treaty with Japan to initiate Japanese rearmament. The issue of Japanese rearmament was a focal point in the Japanese peace negotiation. Washington pressed Japan to rearm rapidly, but Tokyo stubbornly opposed. Under pressure from Washington, the Japanese government established the National Police Reserve and had to expand its military forces during the war. When the Korean War ceased in July 1953, Japanese armed forces numbered about 180,000 men. The Korean War also brought a fundamental change to Japanese economic and diplomatic relations in Asia. With a trade embargo on China following the unexpected Chinese intervention in Korea, Washington wanted to forbid Sino-Japanese trade completely. In addition, Washington pressed Tokyo to recognize the Nationalist regime in Taiwan …

The problem of this study was to determine if at-risk students who were enrolled in an educational support class for one hour a day would have an improvement on the four at-risk indicators being measured over students not enrolled in the academic support program. The four at-risk indicators are grade point average, self-concept, days absent from school, and discipline referrals. The hypothesis formulated for this study predicted no significant difference in mean scores of the four measured indicators between groups. These indicators were measured by the Piers-Harris Children's Self-Concept Scale, official school attendance records, official school transcripts, and the school's discipline records book. The at-risk population was identified from the use of an at-risk indicator scale. After random placement into either the control or experimental groups the samples were divided and analyzed according to grade and gender. The study was conducted over a 12 week period and included students from the Memphis, Michigan School District in grades six through nine. Data were analyzed by the independent means t test at the .05 level. The experimental group means were further analyzed for practical significance and for directional improvement. A series of tables provides a comparison of scores for all students participating …

This study was designed to investigate what course of action therapists and physicians report they would take in reconciling their conflicting duties to maintain confidentiality and protect third parties from harm in HIV-related situations. The physicians surveyed were licensed to practice medicine in Texas and board certified in Internal Medicine. The therapists surveyed were licensed professional counselors in Texas and members of one of three selected divisions within the Texas Counseling Association. A survey instrument developed by the researcher was mailed to 200 subjects randomly selected from each group.
