The purpose of this paper is to present a new electromagnetic device which uses alternating magnetic fields for tracking movements of multiple points inside and outside the vocal tract. It is biologically safe, noninvasive, it does not interfere with speech movements, allows for multiple recording in the same subject, and for easy collection of large amounts of data. It is especially suitable for evaluation of patients with speech motor impairments.  相似文献

The results of an evaluation of the perfusion scintigraphy findings of 350 hospitalised neurological patients and 55 more strictly selected neurosurgical patients with cerebrovascular complaints, revealed an accuraty of 83%, a sensitivity of 89%, and a specificity of 83%. The selection of the patients had no influence on the results as a whole. Compared with contrast-medium angiography, incorrect diagnosis must be expected in 17% of the cases. This includes erroneous negative findings in 10% of the cases. Grounds for misinterpretations are suggested, and the biological and methodological limitations of the method are set forth.  相似文献

Two hundred and sixty three young adult college students responded to openended questions assessing their specific intentions, motives, and plans for having children. The most commonly stated motives for childbearing reflected a strong interest in establishing an identity and social network. Financial, marital, and emotional stability were identified as important factors influencing the timing of parenthood. Several significant sex differences were found for both motives and the timing of parenthood. These findings are discussed in terms of changing social norms regarding parenthood and changing sex role expectations.Portions of this research were presented at the Eastern Regional Psychological Association Convention in New York, April 1986. This research was funded by a grant from Trenton State College, Committee for Faculty and Institutional Research and Sabbatical Leave.  相似文献

Data on 94 women gathered during four field trips to a village located in the Malnad area of Karnataka form the basis of this examination of changes in Havik Brahmin marriage patterns over a 20-year period. Four case studies of marriages and two case studies of single women illustrate social change, particularly the influence of increased education, marriage age, and marriage choice. These case studies illustrate that, with an increase in marriage age and an increase in educational level, women have increased independence as daughters, brides, wives, and mothers. Concurrent with this is a decreased emphasis on ritual. Women have become assertive as they have perceived options. The socialization of women into learned helplessness and absolute dependence on men is in the past. Where women were perceived and perceived themselves as forever childlike, they now have grown to maturity. Men have to acknowledge women's educational achievements, especially when sisters achieve more than their brothers. With the recognition of feminine achievement has come increased independence for women. Mothers who have been bitter about their own limitations have encouraged daughters to achieve. With a change from an ascribed status of men as superior to achieved status based on merit has come increased opportunities for women.  相似文献

The psychotherapeutic life-work of psychiatrist Arthur Kronfeld has almost fallen into oblivion. Against the background of the 100th anniversary of his birth the author traces Kronfeld's psychotherapeutic career, pointing out his activity at the Berliner "Institute of Sexual Research" under Magnus Hirschfeld, and his psychotherapeutic concept--the psychagogic guidance of the patient--and its connection with the individual psychology of Alfred Adler. Kronfeld translated his theoretical positions into activities directed towards socialization and the teachability of psychotherapy which are still worthy of note by those engaged in the field.  相似文献
