Wetland wastewater treatment offers low-cost, energy efficient alternatives to conventional wastewater technologies. In this study, an artificial wetland was constructed at the City of Denton, Texas Pecan Creek Water Reclamation Plant to facilitate diazinon removal from treated effluent.

Black nationalism responded to America's failure to examine the effects of slavery's legacy. Its aims represent those issues that were either unsupported by or in opposition to the goals of the civil rights leadership. In particular, the civil rights movement dismissed any claims that the history of slavery had a lasting effect on African-Americans. This conflict developed because of mainstream America's inability to realize that the black community is not monolithic and African-Americans were differentially affected by slavery's legacy. It is those blacks who are most affected by the culture of poverty created by America's history of slavery who make up today's inner-city populations. Despite successes by the civil rights movement, problems within lower-class black communities continue because the issues of the black underclass have not yet been fully addressed.

Self-concept scores of 19 visually-impaired adults were compared to those of 19 matched sighted adults using the Tennessee Self-Concept Scale (TSCS). All participants attended the University of North Texas. Scores were examined against the Vocabulary and Information subtests of the Wechsler Adult Intelligence Scale-Revised (WAIS-R).

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.

The purpose of this study was to provide descriptive information about values education programs in Texas elementary schools for policy makers, curriculum directors, and educators. Insight into this contemporary issue is augmented by exploring (a) commercially or locally developed values programs that are in place in schools, (b) the relationship between student and school district demographics and values education programs, (c) the role that different interest groups have in the introduction of values education programs, and (d) the extent to which values education programs are accepted by different groups.

This study evaluated the effects of chlorinated effluent discharged from the City of Denton, Texas' wastewater treatment plant on Pecan Creek's fish and macroinvertebrate assemblages, and their recovery upon dechlorination. A baseline of ecological conditions was established while chlorine was present in the effluent (June 1993- October 1993), and was evaluated again after dechlorination with sulfur dioxide (October 1993-August 1994). In situ Asiatic clam and fathead minnow ambient toxicity tests, and fish and macroinvertebrate collections were used to establish this baseline for comparison to post-dechlorination results.

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.

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.

The objective of this research was to determine if physical and microbial sediment characterizations could be used to explain benthic macroinvertebrate distribution in two branches of Lake Ray Roberts, Texas.

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.

This investigation sought to identify linkages between the Texas Supreme Court and public opinion through 1) a matching of written decisions with scientifically conducted public opinion polls; 2) direct mention of public opinion and its synonyms in Texas justices' decisions; 3) comparison of these mentions over time; and 4) comparison of 10 personal attributes of justices with matched decisions. The study moved the unit of analysis from the U.S. Supreme Court to the state court level by using classification schemes and attribute models previously applied to the U.S. Supreme Court. It determined that linkages exist between the Texas Supreme Court's written decisions and public opinion from 1978 to July 1994.

This dissertation is an attempt to give a picture of the Nevada frontier journalist Samuel L. Clemens and the surroundings in which he worked. It is also an assessment of the extent to which Clemens (and his alter ego Twain) can be considered a serious journalist and the extent to which he violated the very principles he championed.

The purpose of this study was to measure music performance program enrollments and course availability for educationally disadvantaged and non-educationally disadvantaged groups (grades 9-12) in Texas, and to further examine relationships which could help music educators understand the role which music performance programs play in the lives of educationally disadvantaged students. Data analyzed were collected by Texas' Public Education Information Management System (PEIMS). Educationally disadvantaged groups under consideration included economically disadvantaged, at risk (as defined by Texas Education Agency guidelines), limited English proficient, as well as Black and Hispanic students. Separate analyses were conducted for band, choir, and orchestra. Subjects included 907,327 students from 1,048 school districts.

The purposes of this study were: (a) to present a brief history of university press publishing in Texas, (b) to describe operating policies and practices of these presses, (c) to compare these policies and practices with commonly accepted principles of publishing policy, and (d) to provide a view of the future of university press publishing in Texas.

The involvement of teachers, parents, and administrators in shared decision making is a critical component in recent attempts to implement site-based decision making in Texas schools. This involvement is usually maintained through the school council, which is the sanctioned forum for discourse as defined by Texas laws. The purpose of this qualitative study was to describe and analyze the content and patterns of decision making discourse in three Texas elementary school councils. The research questions focused on (a) council member role descriptions, (b) training, (c) patterns of deliberation, and (d) varieties of issues discussed. A total of 44 council members participated in the research. Observation, interviews, structured group interviews, decision-making inventories, and documents were used to collect data from December 1992 until January 1994.

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 …

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.

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.

The problem of using a state adopted textbook written to apply to a large body of students with varying interests and needs was overcome by using a detailed syllabus that arranged course content in a meaningful sequence that appealed to student interest. The outlined syllabus prepared a two semester life science curriculum to be used by the teacher to guide lesson planning. Both semesters were divided into three units each. Materials included in the syllabus were given to actual student groups in real classroom settings. Since hands on learning was an important part of classroom instruction, two laboratory sections were included in the appendices to be used with the syllabus.

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 …
