This paper traces the genealogy of the Hotteterre and the Chédeville families through a translation of three works by Jules Carlez, Ernest Thoinan, Nicolas Mauger. Carol Padgham Albrecht annotates these translations with biographical information and highlights the contributions of the instrument makers.

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.

The present study was designed to evaluate the efficacy of utilizing an avoidance conditioning paradigm in EMG biofeedback training and to compare this method to the standard biofeedback training paradigm. Frontalis EMG levels of 20 college students were monitored during non-stress and stress conditions. Half then received standard EMG biofeedback training. The other half received biofeedback with contingent aversive stimulation. Both groups received training to a relaxation criterion of 3 microvolts for 100 seconds or, for a maximum of two 20 minute sessions. Subjects were then monitored again during non-stress and stress conditions. Both groups obtained significant EMG reductions due to training with no significant differences between them. Standard biofeedback training required less time for subjects to achieve the relaxation criterion than did biofeedback with a shock-avoidance contingency. Possible applications of avoidance contingent biofeedback were suggested.

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.

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.

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.

This study investigates the effects of frequency variance on duration perception, using musically trained subjects. In the experiment three silent duration intervals were examined (4.75, 5.00, and 5.25 seconds); each interval was preceded and followed by tone markers. The onset marker was preceded by seven discrete tones one second apart, on the frequency 174.968 Hertz. This established a pulse or an external standard time measure. The subjects made judgments as to whether the offset marker fell "before," "on," or "after," the pulse. The offset marker had a variable frequency. In the study, the direction of the frequency change, the distance of frequency change, and the mathematical intervallic relationships of the two frequencies show possible influence on duration perception.

This study was to clarify strength factors using 12 selected exercises on the Universal Gym, and to determine what measures present a valid method of assessing strength of college-aged males, Eighty-eight males enrolled in beginning weight-training classes used the Universal Gym for twelve weeks, Subjects were tested for maximum strength on 12 exercises, Alpha and canonical factor analyses were performed on raw scores of all measures, and on scores when body weight and standing height variances were removed. A three-factor structure of upper extremity, lower extremity, and trunk strength was revealed when weight, and weight and height combined were statistically controlled. Results showed that residualized scores of weight can be used to evaluate strength on the Universal.Gym,

Wawrzyniec Goslicki's De optimo Senatore was published in Venice in 1568. Subsequent translations of the work had an impact on political thought in England in the seventeenth and eighteenth centuries. Goslicki's work has received little attention since, and this paper is an effort to restore to Goslicki his place of importance in Polish history and western political thought. The paper provides a brief biography of Goslicki; an account of the English translations and historiography surrounding De optimo Senatore; an analysis of Goslicki' s political thought; and, an explanation of his influence on William Shakespeare.

Two aspects of the biological activity of N-nitrosamines were studied. First, the effect of ascorbate on the mutagenicity of N-nitrosopiperidines was studied in the Ames Salmanella/ mammalian microsome mutagenicity test. The addition of ascorbate significantly enhanced the mutagenicity of these compounds. This enhancement was selective for N-nitrosamines suggesting a possible role of ascorbate in N-nitrosamine induced carcinogenicity. Second, the technique of velocity sedimentation in alkaline sucrose density gradients was applied to the detection of N-nitrosamine induced DNA damage in Balb/c 3T3 cells. This technique detected N-nitrosamine induced DNA damage when the cells were made permeable before treatment. This technique compares favorably with other test systems used to evaluate N-nitrosamines and should be useful in further studies of N-nitrosamines.
