A Survey of the Twentieth Century American Trends in Secondary Mathematics Education

Description: This investigation of twentieth century trends in mathematics education includes the survey of existing literature and questionnaires conducted with retired and active Texas teachers. Historical events, trends in curriculum, instruction, learning theories, and contradictions of twenty-year periods are delineated. Questionnaire responses are tabulated along the same periods and vignettes of typical classrooms are drawn from the data. Results of the survey show the impact of societal forces on mathematics curricula, a continued downward expansion of content into lower grades and expanding knowledge of learning processes. A unified mathematics curriculum, classroom-related learning theory research, and further development of team-teaching are postulated as future trends. Recommendations include further examination of trends through isolation of other variables such as region and ethnicity.

Size Fractionation of Metabolically Active Phytoplankton and Bacteria in Two Diverse Lentic Systems

Description: Simultaneous size fractionation of plankton populations associated with NaH^14CO_3 and ^3H-glucose uptake was employed in eutrophic Lake Texoma (Texas and Oklahoma) and oligotrophic Flathead Lake (Montana). Autoradiography was utilized to determine the role of specific microorganisms in community metabolism. Ultraplankton (0.45-10 μm) dominated plankton numbers and metabolic activity in both aquatic systems. Many of the most abundant species were not the most productive, in terms of inorganic C fixation. Rates of heterotrophic uptake of ^3H-glucose were small in comparison to photolithotrophic uptake in both lakes, Photoheterotrophy was more extensive in Flathead Lake, Autoradiographs indicated that bacteria were responsible for observed photoheterotrophy. Oscillatoria sp. exhibited. mixotrophy in Lake Texoma,

Genic Differentiation Between Two Chromosomal Races of Pocket Gophers, Geomys bursarius

Description: Genic data from two chromosomal races of Geomys bursarius from a contact zone in central Texas indicated that the two races possessed distinct gene pools which would define them as separate species. Data from proteins encoded from 21 loci in this study substantiated this hypothesis. A pattern of alternately fixed alleles at the ADH-l, MDH-2, LDH-l, and IDH-1 loci with no apparent gene flow in zones of contact strongly suggested that these two races should be designated as separate species. Levels of heterozygosity and high FST values indicate that genomic structuring within Geomys is most heavily influenced by high levels of inbreeding and low migration rates. Fossorial rodents were suggested to undergo speciation primarily through parapatric means.

Personality Variables Relating to Facet Denervation Response

Description: The disabling conditions of chronic low-back pain continue to cost patient, family, and society. The intricate mechanisms which perpetuate this medical condition often consist of both organic and functional factors. This study evaluated personality and psychosocial variables which may control individual responses to facet denervation, a treatment for chronic lumbar distress. The subjects were 47 chronic pain patients whose symptoms conformed to the facet syndrome. Patient responses to the Minnesota Multiphasic Personality Inventory (MMPI) and the Sixteen Personality Factor Questionnaire were reviewed in an effort to predict statistically symptomatic relief. Also, the patients' involvement in litigation and their accuracy in determining their pain level were studied as possible influencing variables. Results show the litigation factor and two scalesof the MMPI to be most useful in predicting patient response from facet denervation treatment.

Duals and Weak Completeness in Certain Sequence Spaces

Description: In this paper the weak completeness of certain sequence spaces is examined. In particular, we show that each of the sequence spaces c0 and 9, 1 < p < c, is a Banach space. A Riesz representation for the dual space of each of these sequence spaces is given. A Riesz representation theorem for Hilbert space is also proven. In the third chapter we conclude that any reflexive space is weakly (sequentially) complete. We give 01 as an example of a non-reflexive space that is weakly complete. Two examples, c0 and YJ, are given of spaces that fail to be weakly complete.

Patient Behaviors: Development of a Rating System

Description: The patient's failure to cooperate effectively in the patient/physician (patient and physician) interaction has been shown to be a problem of significant magnitude. In the present study, an attempt was made to identify specific, patient behaviors which might be related to physician judgment of a good patient and progress of treatment. A checklist of 37 behaviors was compiled. A series of 100 patients was observed during their interaction with physicians and occurrences of behaviors from the checklist were noted by an experimenter. Physicians also indicated whether the patient was considered to be a good patient and whether treatment was progressing as expected. For every third patient, physicians noted the occurrence of behaviors from the checklist. An association was found between some behaviors from the checklist and the physicians' judgment. There was also shown to be a difference in the ability of the experimenter and the physicians involved to detect these behaviors.

The Electronic Spectrum of (-)-S-(pS)-2,5,3',6'-Tetrahydro-2.2-Paracyclophane-2-Carboxylic Acid

Description: A new, efficient route was used in the synthesis of [2.2]-paracyclophane-2-carboxylic acid. The acid as then resolved and the Birch reduction performed yielding one enantiomer of tetrahydro-[2.2]-paracyclophane-2-carboxylic acid. The ultraviolet spectrum of tetrahydro-[2.2]-paracyclophane- 2-carboxylic acid in isopenthane shows one absorption at 206 nm (Emax = 5,271). There are three bands observed in the circular dichroism spectrum in isopentane at 236 nm ([] = 1.8 X 104), 201 nm ([0] = -16 X 104) and a positive band indicated below 180 nm but not observed. The bands were assigned and possible reasons for the occurrence of a mr'r* transition at unexpectedly long wavelengths are discussed.

Peer Counselor Effectiveness in a Study Skills Course

Description: Research has demonstrated the efficacy of attitudinal-motivational counseling in conjunction with study skills training. However, it has not been clear whether group or individual counseling was most beneficial. This research attempted to evaluate the usefulness of peer counselors in group and individual counseling sessions. Using students voluntarily enrolled in a study skills program, it was demonstrated that all students improved in study habit scores. However, only individual-peer counseling was effective in changing academic attitudes (p < . 05), as compared to group-peer counseling, no-counseling, and no-treatment conditions. Grade-point-average change scores were not differentially effected by the treatment conditions.

Conditioned Reinforcement with an Equine Subject

Description: Historically, horse trainers have relied primarily upon repetition, negative reinforcement, and punishment to teach new behaviors. Positive reinforcement has been eschewed, largely on the basis of the wides read belief that positive reinforcement is not effective with horses. Additional difficulties in the timely application of such reinforcement have further inhibited its use. After repeated pairing of an auditory stimulus with an established primary reinforcer, the auditory stimulus was predicted to be a reinforcer. An equine subject was then successfully trained to perform five different, novel tasks using only the auditory stimulus. Subsequently, extinction of behavior was noted in the absence of the conditioned reinforcer. Implications for many phases of horse training were discussed. Some weaknesses of the present study were noted along with suggested issues for future investigations.

Treatment of Preorgasmic Women Utilizing Group Threapy [sic] and Home-Based Training

Description: There have been various approaches to the treatment of nonorgasmic women, including psychoanalysis, desensitization, relaxation, masturbation, and group therapy. The present study was conducted to examine the efficacy of group therapy combined with home-based training in the treatment of primary nonorgasmic women. A no-treatment control group was also employed. Treatment consisted of two weekly 1- hour group sessions for 5 weeks. Educative processes were employed, such as detailed information on physiology of female sexual response. Structured homework exercises were also utilized, such as mastubatory techniques, role-playing orgasm, strengthening vaginal muscles, and assertiveness training in sexual and nonsexual situations. Results indicated an 88% success rate in the treatment group and no change in the control group.
