Spatial and Temporal Influences of Water Quality on Zooplankton in Lake Texoma

Description: 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 water quality parameters supporting the presence of longitudinal gradients of differing water quality. Three independent models (Red River arm, Washita River arm, Main Lake body) rather than a single model for the entire reservoir, best describe patterns in the zooplankton community and its relationship to seasonal, physical and chemical factors. Statistical power, sample size and taxonomic resolution were examined. When monitoring seasonal and annuals trends in abundance, the greatest statistical power was achieved by analyzing count data at taxonomic levels above genus. Taxonomic sufficiency was assessed to determine if costs could be reduced for zooplankton identifications. For water quality monitoring ...

A Proposal for the Establishment of a Low-Power, Frequency Modulated, Educational Radio Station as Exemplified by Oklahoma Baptist University

Description: The purpose of this study was to investigate the various aspects of low-power frequency modulation educational broadcasting and to formulate from the findings a guide for the establishment of stations on campuses as exemplified at Oklahoma Baptist University. It is hoped that this report will provide detailed information of interest and value to that university, its staff, its present and future scholars, and to other school and individuals interested in building an educational broadcast facility.

A Bacteriological Survey of a Freshwater Reservoir

Description: In this study organisms that can be subcultured from lake water, using a prescribed procedure, limit, to an extent, the population, or portions of the population, that can be monitored. In essence, what is taking place is that a set of conditions is set forth and a study is made of the bacteria that will grow under these prescribed conditions.

The Effects of Hexadecanol on the Microbiota of Lake Hefner

Description: 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.

A Study of the Perceptual Factors which are Involved in Performance on the Bender Visual Motor Gestalt Test

Description: The purpose of the present study is to try to establish if perception is a determinate factor of performance on the Bender Gestalt Test. In a study which is attempting to determine the effects of perceptual factors as compared to motor factors on the Bender Gestalt Test, it would seem necessary to separate the two factors.

The Relationship Between Dogmatism and Neuroticism in Supervisors of Sheltered Workshops and Changes in the Self-Concept of Handicapped Employees

Description: The problem with which this investigation is concerned is whether or not dogmatism and neuroticism in supervisors of sheltered workshops is related to changes in the self-concept of handicapped employees. The measurements of dogmatism and neuroticism were accomplished through the use of Rokeach's Dogmatism Scale, (form E) and Winne's Neuroticism Scale. Pitt's Tennessee Self Concept Scale was used to measure the self-concept of the handicapped employees.

A History of WKY-AM

Description: 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 Efficacy of the Chickasaw Nation Early Care and Education Programs

Description: 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. There was little evidence to support culturally relevant pedagogy alignment with curriculum and practices. Implications for additional research focusing on American Indian children in preschool programs and the importance of instilling pride and culture are recommended.

Drumming Behavior of Selected North American Stoneflies (Plecoptera)

Description: Drumming is first described for five North American stonefly species, Acroneuria evoluta, Doroneuria baumanni, Isoperla namata, Chernokrilus misnomus, and Pictetiella expansa. Signals of Acroneuria lycorias, Phasganophora capitata and Isoperla signata are further described. Drumming was not recorded from Amhinemura delosa. Signals of A. evoluta are the most complex yet recorded in Plecoptera. Doroneuria baumanni, P. expanse, C. misnomus and P. capitata have 2-way exchanges. Male D. baumanni produce two prolonged beats by rubbing the hammer on the substratum; male-female signals are non-overlapping in the first two species and overlapping in the latter two. Female P. capitata answered with an unusually long sequence of beats. Two male Isoperla species produced monophasic calls without female answers. Female A. lycorias answered taped male signals with monophasic signals like all observed females.
