A technique employing diagnostic ultrasound to evaluate lateral pharyngeal wall motion during connected discourse is described. The validity and reliability of the procedure are discussed. Typical displacement patterns are shown for normal speakers and applications to cleft palate and laryngectomized speakers discussed. 相似文献

Evaluated anxiety and performance on concrete and abstract criterion-referenced mathematics tests for 267 1st and 2nd graders assigned to either individualized multiage programs (IMP) or traditional learning environments (TRAD). The State-Trait Anxiety Inventory for Children (STAIC) was used to measure anxiety. Lower trait and state anxiety was associated with the IMP program, and anxiety-reducing effects were greater for 2nd graders. High A-Trait 1st graders performed more poorly than low A-Trait 1st graders. Although IMP 1st graders were lower in A-Trait than TRAD children, they did not differ in performance. For 2nd graders, the IMP environment facilitated the performance of high A-Trait children, but resulted in poorer performance for low A-Trait children.

J. Kellerman (see record 1979-26395-001) argues that use of psychiatric patients in a study designed to search for psychosomatic etiological factors in neoplasms may have led to the present authors' negative results (see record 1978-03712-001). It is suggested, however, that the use of psychiatric patients increased the heterogeneity of the sample and probably enhanced, not limited, the likelihood of positive findings. It is also suggested that the inclusion of alcoholics in the study may have masked real differences between neoplasm and control Ss. However, new analyses run on subsets of the malignancy and malignancy-control samples from which alcoholics were first deleted failed to support his contention. New analyses run to test for differences between the frequencies of various high-scale MMPI types in neoplasm and control groups also failed to support the view that neoplasm patients are qualitatively different from controls on the inventory.

Two studies were conducted to explore the relation between (a) experience in counseling and psychotherapy and (b) ethical knowledge. In Study 1, 77 college students reported their experience as clients in a variety of settings and then completed a questionnaire concerning their knowledge of ethical issues. The hypothesis that clients (subjects who had counseling experience) would demonstrate ethical knowledge superior to that of nonclients (those with no such experience) was not supported. Ethical knowledge did not differ as a function of counseling experience, the setting in which counseling was received, or the number of sessions. However, though overall ethical knowledge was high across groups, knowledge with respect to each ethical issue was incomplete. In Study 2, following the same procedure, we compared 17 current psychotherapy clients at a Veterans Administration medical center with 15 nonclients, patients in the hypertension clinic who had never received psychological services. These clients demonstrated superior ethical knowledge on specific issues (.008?ps? 相似文献

The results of a case study in which over 100,000 Pascal program executions were monitored for run-time errors are reported. A large number of run-time errors in a wide variety of categories were observed. The data reported provided insight into the use and misuse of the features of Pascal by a large population of programmers. Some implications of these statistics on compiler implementation and programming language design are discussed. The number and variety of errors detected suggests that run-time checking mechanisms are more important and useful than is generally recognized, judging by the incompleteness of such mechanisms in many compilers. 相似文献

The way public authorities presently define the homeless in the United States carries forward a complex historical legacy. The causal and moral assessments of the homeless, grounded in the work ethic of our capitalist society, have left behind four interpretations of the homeless as vagrant, deviant, sick or victim. Analysis of recent studies of the homeless, while uncovering the presence of all four definitions, found that most of the ‘new’ homeless are victims of the economy or sick. 相似文献

"The Extraversion and Neuroticism scales of the Maudsley Personality Inventory were administered to 72 college students who were dichotomized on the basis of their scale scores. The inverted alphabet printing task was used to provide measures of motor learning performance. Analyses of variance of the motor learning scores showed that the women learned significantly faster than the men, but the main effects of Extraversion and Neuroticism were not significant." 17 refs.

Some effects of the addition of cobalt to the nickel hydroxide electrode 总被引:15,自引:0,他引:15
R. D. Armstrong G. W. D. Briggs E. A. Charles 《Journal of Applied Electrochemistry》1988,18(2):215-219
The action of cobalt upon the characteristics of the nickel hydroxide electrode has been investigated by constant current, linear potential sweep and EDAX methods. It was found that cobalt raises the oxygen overpotential and promotes greater utilization of the active material, although major additions of cobalt were observed to lower the working potential of the electrode. It was also found that cobalt prevented any significant loss of electrode capacity when the system was poisoned with iron. 相似文献
