Parental attitudes about sexual education: cross-cultural differences and covariate controls.

Cross-cultural differences in parental attitudes and experiences of childhood sexual education were examined. Parental attitudes and experiences were isolated for study because of their significance as a vehicle for transmitting culturally prescribed norms. The present study also tested for artifactual differences between cultures, in terms of explaining the differences with concomitant variability. Couples with children ranging in age from 1 to 10 were utilized and were drawn from four subcultures (Mexican-American, N = 22, Black American, N = 20, Caucasian American, N = 27, and Japanese-American, N = 18). The most salient and consistent finding was the pronounced significance of the covariate controls (especially father's education and mother's religiosity). That is, although a few cross-cultural effects remained significant despite the influence of a covariate, most of the findings were biased by a concomitant (i.e., demographic) variable.

Thermographic measurement of sexual arousal: a discriminant validity analysis.

Thermographic measurement was discovered to be a valid method for assessing human sexual arousal, in that it achieved adequate discriminant validity and that it covaried with self-reports of sexual arousal. The advantages of this procedure over other physiological methods are that it provides a thermogram indicating flow rate and transfer of heat, allows for cross-gender comparisons, and is a more ecologically valid method of assessing sexual arousal.

Thermographic measurement of sexual arousal: a methodological note.

A thermographic measure of sexual arousal in terms of the four stages of sexual stimulation (excitement phase, plateau phase, orgasm phase, and resolution phase) articulated by Masters and Johnson (1966) is described. A male and female masturbated to orgasm; the results are presented in terms of interpretations of both the thermographic image and the quantitative temperature profile. Possible future research applications are suggested, including sexual dysfunctions, sexual arousal, and gender differences.

Anesthesia for prolonged bronchoscopy.

At the Mayo Clinic, experience with 22 patients undergoing bronchoscopy on 29 occasions has shown that prolonged operative manipulation in the airway can be carried out safely and satisfactorily using general anesthesia. Requisites for this procedure include a period of apneic oxygenation, an adequate-sized endotracheal tube, hyperventilation of the patient during operative manipulation, and careful attention to management of postoperative bronchospasm. Prolonged bronchoscopy under general anesthesia has permitted localization of occult bronchogenic carcinoma at an earlier stage than has been possible up to this point.

Plasma dopamine-beta-hydroxylase activity and catecholamine levels in anesthetized dogs following acute hemorrhage.

Because dopamine-beta-hydroxylase (DBH) is released from storage vesicles in adrenergic nerves and the adrenal medulla along with catecholamines, determination of circulating levels of this enzyme might serve as an index of sympathoadrenal activity. This hypothesis has been studied in dogs anesthetized with cyclopropane, isoflurane, and thiopental that were subjected to a single acute hemorrhage and followed for 5 hours. Plasma DBH activity and catecholamine levels were determined before and every 30 minutes after the hemorrhage. Changes in DBH activity did not correlate well with changes in levels of circulating catecholamines in the dog in response to this form of stress.
