Decelerative cardiac responsiveness to acoustical stimulation in the near term fetus 总被引:1,自引:0,他引:1
Jean-Pierre Lecanuet Carolyn Granier-deferre Anne-Yvonne Jacquet Marie-Claire Busnel 《The Quarterly Journal of Experimental Psychology Section B: Comparative and Physiological Psychology》1992,44(3):279-303
Human fetal cardiac responses (36-39 weeks gestational age) to brief, repeated vocal stimuli (male or female voice uttering the same sentence), given at 90-95 dB SPL ex utero (around 20-30 dB less in utero) during a state of low fetal heart rate (FHR) variability, were examined using highly conservative statistical criteria taking into account each subject's prestimulus FHR variability. Subjects exposed to either of the two stimuli displayed significantly more decelerative heart rate (HR) changes compared to control subjects receiving no stimulation. The decelerative changes started during the first seconds following the onset of stimulation and reached their amplitude peak within 10 or 20 sec, depending on the subject. The directions—HR acceleration or deceleration—and the amplitude of the response depended on prestimulus HR variability only, not on prestimulus level. No major difference was found between the effects of the two voices. The data are compared to previous studies demonstrating fetal decelerative changes to acoustic stimuli of less than 105 dB SPL. The choice of an objective criterion to define an HR response and the possible orienting response nature of the decelerative change are discussed. 相似文献

Five hundred and fifty-eight cigarette smokers (mean 31 cigarettes/day) were randomized in four groups: Acupuncture, Behaviour Therapy, Placebo Medication and Waiting-list Control. The life-table analysis of smoking cessation showed, at a 12-month follow-up, no difference between Acupuncture, Behaviour Therapy and Placebo. Differences appeared only in an analysis of the abstinent subjects at each data point. Behaviour Therapy and Acupuncture accounted for significantly more abstinent subjects than Placebo at the end of the 2-week therapeutic phase. However at 9 and 12 months Acupuncture had a statistically-significant greater number of abstinent subjects than Behaviour Therapy, but there was no difference between Acupuncture and Placebo. The percentage decrease in smoking from baseline appeared significantly greater at 12 months in the first three groups than in the Control conditions. However, as in most smoking-cessation studies, the overall effect was small and non-specific. The results reflect the importance of maintenance programmes and of the prevention of addiction. 相似文献

Approximations form an essential part of scientific activity and they come in different forms: conceptual approximations (simplifications in models), mathematical approximations of various types (e.g. linear equations instead of non-linear ones, computational approximations), experimental approximations due to limitations of the instruments and so on and so forth. In this paper, we will consider one type of approximation, namely numerical approximations involved in the comparison of two results, be they experimental or theoretical. Our goal is to lay down the conceptual and formal foundations of a local theory of partial truth. This is done by introducing and exploring the concept of truth space. 相似文献

Reviewing the publications of prominent American rabbis who have (extensively) published on Jewish biomedical ethics, this
article highlights Orthodox, Conservative and Reform opinions on a most pressing contemporary bioethical issue: euthanasia.
Reviewing their opinions against the background of the halachic character of Jewish (biomedical) ethics, this article shows
how from one traditional Jewish textual source diverse, even contradictory, opinions emerge through different interpretations.
In this way, in the Jewish debate on euthanasia the specific methodology of Jewish (bio)ethical reasoning comes forward as
well as a diversity of opinion within Judaism and its branches. 相似文献

This study presents the validation of the Authentic Leadership Questionnaire (ALQ) in a sample of more than 600 Spanish employees. This questionnaire measures four distinct but related substantive components of authentic leadership. These components are: self-awareness, relational transparency, balanced processing, and internalized moral perspective. Structural equation modeling confirmed that the Spanish version of ALQ has high reliability and predictive validity for important leadership outputs such as perceived effectiveness of leadership, followers' extra effort and satisfaction with the leader. 相似文献

Medical thrillers have been a mainstay of popular fiction since the late 1970s and still attract a wide readership today. This article examines this specialized genre and its core conventions within the context of professionally-based fiction, i.e. the class of thrillers written by professionals or former professionals. The author maps this largely unchartered territory and analyzes the fictional representations of doctors and medicine provided in such novels. He argues that medical thrillers, which are not originally aimed at specialized readers and sometimes project a flawed image of medicine, may be used as a pedagogical tool with non-native learners of medical English. 相似文献
