It seemed desirable to investigate more fully the effect of hexadecanol on the microbial population of a reservoir. It was the purpose of this investigation to determine the effect of hexadecanol on the micro-biota of Lake Hefner, to ascertain which organisms were stimulated by hexadecanol both in the laboratory and the reservoir, and to investigate the degradation of hexadecanol by microorganisms selected from Lake Hefner.

This study investigated the relationship between certain biographical and personality characteristics and decision-making ability of purchasing personnel as measured by the results achieved in a complex management game.

Adult stonefly emergence, nymphal growth, drift and microdistribution were examined in Battle Branch, a secondorder, spring-fed stream, from November, 1982 to May, 1984. Adults of 22 species emerged successionally, with specific adults present every month. Searching emergent objects and the stream margin was best for collection of winter and early spring emerging species. Sweeping the streamside and light trapping were most efficient for late spring and summer emerging species. Nymphal growth for nine abundant species generally fit double log or semilog models. Drift was low, but did show a post-sunset pulse. Generally, leaf material was found to be significantly related (p<O.001) to density, diversity and biomass of stoneflies in Battle Branch.

Etheostoma spectabile, E. punctulatum, and Cottus carolinae were sampled Mar., 1983, - Feb., 1984, in Flint Creek, Oklahoma. Immature E. spectabile ate primarily microcrustaceans, while mature fishes relied more on mayflies and amphipods. Juvenile E. punctulatum fed upon mayflies, amphipods, and Asellus. Mature E. punctulatum ate primarily mayflies, and other relatively larger prey. Cottus carolinae consumed chironomids almost exclusively in Jan. - Feb., 1984, while mayflies were predominant the remainder of the year. No significant habitat partitioning between the two darters, and seasonal habitat segregation between C. carolinae and the two darters was found. Dietary overlap between the darters was significantly correlated (p<0.0005) to differences in x prey sizes.

This study was conducted to examine the use of microcomputers and other computers by top administrators in the twenty—seven public colleges and universities in Oklahoma; to assess the impact that training and other factors have on the extent to which microcomputers are being used; and to identify trends in administrative computer usage. The survey technique was utilized in collecting the data for this study. The survey instrument was developed for use in this study from a review of the literature, an evaluation by a panel of judges, and a pilot study. The survey instrument was sent to the administrators for business, academic, and student affairs via the president of each university in the 1986 spring and summer semesters. Seventy-four of the eighty-one or 91.4 percent of the administrators responded. Following is a summary of the major findings of this study. 1. Fourteen of the seventy-four or 18.9 percent of the respondents personally use a microcomputer and 51.3 percent of the respondents have someone use a microcomputer on their behalf. 2. The most prevalent use of microcomputers is word processing; the most prevalent uses of mainframes are word processing and database management; and the majority of the respondents do not use …

This study concerns the characteristics of fund development directors employed in selected homes for the aged. The first purpose of this study is to develop a profile of job functions, through task analysis, among development directors in charitable homes for the aged. The second purpose of this study is to develop a profile of personal characteristics of development directors of charitable homes for the aged based on the following characteristics: age, sex, educational background, experience outside development, membership in community organizations and amount of specific training in fund development. One instrument was used to gather data for the study. It was distributed to a population of 29 development directors in charitable homes for the aged in Arkansas, Louisiana, Oklahoma, New Mexico, and Texas. This population was predetermined by an initial survey form sent to 193 chief executive officers in the five states mentioned above. Twenty-nine reported formalized programs employing a full-time person with at least a part-time involvement in fund development activities. Of the twenty-nine development directors surveyed, fifteen usable instruments were received (52 percent). A program was used for the survey that included crosstabulation of social characteristics, success in fund raising, length of time in position and educational preparation. …

The study is a contextual analysis of flood victimization. Victimization is defined as the social, psychological, and physiological aftermath experienced by victims of a disaster. Disaster researchers concentrate on the victims' characteristics to explain the varying degrees of their victimization, providing only ambiguous results. Theorists such as Kreps, Wildavsky, and Douglas contend that the outcomes of disasters are contingent upon social structure. This analysis treats victimization as one such outcome. The condition and behavior of individuals can be explained by the presence of disaster and the conditions of social organization. A model explains victimization based on individual's attributes (individual resources), his social environment, and the disaster characteristics. This study uses the 1984 Mingo Creek Flood Victims Survey data to test the model. The data contain information measuring victimization. The survey data are linked with 1980 Census tract data. The tract data provide indicators of the social networks. This tract information, the contextual variables, taps the social conditions, including poverty, unemployment, geographic mobility, and family patterns. This study uses factor analysis to identify the dimensions of victimization. Regression tests the relationship between the contextual variables, the individual resource variables, the disaster characteristic variables, and victimization. The results of the analysis show …

A case study was conducted to document the changes in the attitudes of academic administrators at Langston University with regards to the use of various types of information sources for strategic planning. Environmental scanning of external factors was accomplished for six months by the use of a selective dissemination of information (SDI) service. Pre- and post-assessments of the perceived reliance on, satisfaction with and adequacy of personal and library-type information sources were conducted. Findings indicated the continued reliance on personal sources. No statistically significant changes were found in perceived adequacy levels in the use of library-type materials. The overall satisfaction level for the use of library-type information sources and retrieval methods showed a significant increase. Further study is recommended that will utilize additional information technology and other academic institutions.

The problem of this study was to document the history of radio station WKY, Oklahoma City, and to locate its place within the development of American radio broadcasting. This thesis divides WKY's history into two periods: 1920 through 1925, the years it was operated by Earl Hull, and 1926 through 1989, after it was acquired by E. K. Gaylord. The purpose of this study was to record the history of the oldest radio station operating west of the Mississippi River, its effect on the broadcast industry in general, and its effect on Gaylord Broadcasting Corporation, the parent organization. The study also explored the innovations. in both programming and engineering that caused the station to grow into one of the most popular radio stations in the Southwest, as well as its decline in recent years.

The purpose of this study was to investigate the interpersonal influences which Bohumil Makovsky, Director of Bands and Chairman of the Music Department at Oklahoma A&M College from 1915 to 1943, had on his students and peers, as confirmed through the perceptions of selected individuals, and to determine what personal characteristics and means he drew upon to induce changes in his students and peers.

The purpose of this study was to compare four different methods of bibliographic instruction in order to determine which method would have the most effect on student learning.

The primary purpose of this study was to identify and secure perceptions of what personal and institutional factors influenced and attracted adult students to enroll in four year institutions in Oklahoma. The secondary purpose was to compare student responses by institution. The more notable findings include: (1) dominant personal factors as to why adult students in this study returned to college were reportedly to improve/advance themselves, especially as it relates to their career; (2) flexible class scheduling was reported to be the most important institutional function for recruiting adult students, with academic quality and institutional costs of education next in importance; (3) almost 90% of respondents reported being under 45 years of age; (4) almost 85% reported commuting fewer than 50 miles to class; (5) approximately 90% reported enrolling each fall and spring (6) approximately twice as many respondents who returned to college reported they did so because it was more important to them to complete an unfinished degree than to begin a degree. Conclusions drawn from this study are as follows: (1) adult students appear to be unlikely to enroll in classes meeting more than three times a week; (2) adult students in Oklahoma may no longer be described …

Ways in which educational structures can initiate and facilitate older learners' self-directed learning projects are described in this study. The research was guided by questions related to the ways that educational organizations can facilitate the learning process for older learners. This study involved two distinct phases of research. In the first phase, a survey was administered to approximately 100 older learners at four organizations for senior citizens; the four organizations were Hillcrest Center for 55+, Golden Learning Opportunities and Workshop, Tulsa Senior Services, and Retired Senior Volunteer Program. The survey enabled the researcher to identify the 10 most frequented sites for gathering information related to the learning projects of senior citizens in Tulsa, Oklahoma. The survey respondents were volunteer participants from classes, social occasions, and other learning opportunities offered by the organizations. The survey produced three sites where older learners pursued learning activities. Phase two involved ethnographic techniques in order to identify and describe at each three sites specific educational structures that facilitated older learners' self-directed learning projects. The descriptions from each of the identified sites involved three data-collection techniques. The data-collection techniques used included interviews, observation, and artifact collection. The focus of this phase was to describe the educational …

The south-central United States serves as an important biogeographical link and dispersal corridor between Nearctic and Neotropical elements of western hemisphere odonate faunas. Its species are reasonably well known because of substantial collections, but there has been no concerted effort to document the extent of biodiversity and possible geographic affinities of dragonflies and damselflies of this region. The recent discoveries of Argia leonorae Garrison, Gomphus gonzalezi Dunkle and Erpetogomphus heterodon Garrison from southern and western Texas and northern Mexico suggest that Odonata species remain to be discovered in this area, particularly from far south Texas and northern Mexico. I have documented a total of 12,515 records of Odonata found in 408 counties within the south-central U.S. A total of 73 species of damselflies and 160 species of dragonflies was revealed in the region. The 233 (197 in Texas) Odonata species are distributed among 10 families and 66 genera. Illustrated family, generic, and species-level keys are provided. Since the beginning of this work in the Fall of 1993, one species has been added each to the Louisiana and Oklahoma faunas, and 12 species have been added, previously unreported from Texas, including four new to the U.S. The area of highest Odonata …

Seventy-one aquatic species including the copepodids and nauplii were identified from Lake Texoma from August 1996 to September 1997. Zooplankton community structure, abundance and spatial and temporal distributions were compared among five lake zones delineated a priori based on chloride concentration. The zones, in order of decreasing chloride concentration, are the Red River zone (RRZ), Red river Transition zone (RRTZ), Main Lake zone (MLZ), Washita River Transition zone (WRTZ) and Washita River zone (WRZ). Bray Curtis Similarity Index showed community structure was most similar in the two Red River arm zones, the two Washita River arm zones and the MLZ. Zooplankton abundance was greatest in the Red River arm (312 org/L), intermediate in the Washita River arm (217 org/L) and least in the Main Lake body (103 org/L). A significant increase in the abundance of a deformed rotifer, Keratella cochlearis, was observed mainly in the Red River arm during a second study from March 1999 to June 1999. Seasonal dynamics, rather than spatial dynamics, were more important in structuring the zooplankton community, especially in the two river arms. Spatial variance was solely attributed to station and zone effects independent of time for a few crustacean species and many of the …

The purposes of this research were to explore the effectiveness of the Chickasaw Nation early care and education program in promoting school readiness while infusing tribally relevant values in children from birth through age five; engaging parents in all aspects of their children’s learning; and supporting children and families through the transitioning to kindergarten. The study used qualitative methods to examine the experiences and perceptions of ten parents, ten teachers, and five administrators within Chickasaw Nation’s early care and education system regarding the four basic areas of school readiness, parent engagement, transition, and culturally relevant pedagogy. Four primary themes emerged from the semi-structured interviews: 1) socialization, school readiness, and transition, 2) learning, curriculum, and assessment, 3) the role of parents, and 4) cultural integrity. Data were collected through semi-structured interviews, transcribed, and analyzed based on four research questions. Findings indicated parents, teachers, and administrators were satisfied that the program was successful with assisting children in making progress toward achieving developmental and school readiness goals and that the children were physically, socially, emotionally, and cognitively prepared to enter kindergarten. The program provided activities to encourage and promote parental involvement; however, parents did not indicate active involvement or participation in the activities. …

Classrooms, libraries, student unions, and university campuses shape students’ learning experiences. These physical learning spaces set the stage for college student engagement and academic performance. Most of the research about the role of physical spaces in learning lacks the student perspective. The goal of this study was to offer a student-centered vision of ideal learning spaces. Students are the learners for whom learning spaces are designed, and this thesis examines the way students of one summer class at Oklahoma Baptist University conceptualized and interacted with their learning spaces. Data collection included surveys of the students, a focus group with members of the class, participant observation in the classroom, and interviews with students and the professor. Students viewed physical spaces as the backdrop for human action and chose spaces that supported their learning styles and goals. Students described supportive spaces as warm, purposefully crafted spaces, and full of other people who were seriously pursuing the same goals. This thesis explores the ways students conceptualized and interacted with learning spaces as a network of support for their learning and provides recommendations for the design of learning spaces that facilitate this support.
