A mailed survey of female prenatal genetic counselors, obstetric nurses, and high school biology teachers was conducted to determine if these groups hold different attitudes toward genetic risk and to investigate the extent to which any differences result from the effect of different professional experiences. In this study, the participants were 166 genetic counselors, 116 obstetric nurses, and 78 biology teachers (n = 360). Survey participants completed a written questionnaire designed to assess their numeric estimate of the empiric risk for birth defects/genetic problems, their subjective perception of this risk, and their personal use of prenatal diagnosis. Genetic counselors were found to be less likely than the other groups to consider the frequency of birth defects/genetic problems as rare and were 10 times more likely than nurses and 8 times more likely than teachers to have had prenatal diagnosis. Furthermore, more than half of the prenatal diagnosis procedures had by genetic counselors were not medically indicated. These results suggest that genetic counselors have an increased perception of genetic risks relative to nurses or teachers. Possible explanations for this finding are discussed, and the potential role of discordant risk perception in creating biases in the genetic counseling process is explored. 相似文献
By applying results from in-depth interviews with older Iranian Sufis residing in Sweden, this article describes the benefits of the value system of Sufism prizing mystical union above self-realization. As persons conceive of themselves as all forming parts of other-than-self rather than as separate selves, the result is tolerance towards other people's opinions and the vanishing of hostile feelings and competition. Compassion and identification with the whole of creation allows Sufis to avoid the sense of loneliness and exclusion felt by so many immigrants. 相似文献
This study tested the hypothesis that breathlessness in asthma relates linearly to airway obstruction when situational, attentional and emotional influences are held constant via random presentation of different intensities of externally applied airflow obstruction. Adolescents with stable asthma and normal controls (n=25+25) with lung functions of approximately 3.5 l forced expiratory volume in 1 s (FEV1) breathed through a device which obstructed airflow with five stimulus intensities, analogous to a mean reduction in FEV1 of 8–66%. A session consisted of 10 blocks, each with presentation of five stimulus intensities plus the baseline resistance of the apparatus. Breathlessness was continuously reported by moving a lever along a 10-point scale. The mean breathlessness was computed per stimulus intensity. Lung function and anxiety were measured before and after the test.
Participants with asthma, not controls, manifested a paradoxical response: they reported significantly more breathlessness, but undifferentially. One patient against 12 controls reported consistently more breathlessness from baseline to severe obstruction. The hypothesis was only supported for controls. Breathlessness did not correlate with severity of asthma, lung function, duration of asthma, number of exacerbations over the last six months, age, sex or anxiety.
It was concluded that the meaning of airflow obstruction in patients with asthma has changed and underlies their paradoxical responses, even when situational, attentional and emotional factors are controlled. 相似文献
Sixteen right-handed participants (8 male and 8 female students) and 16 left-handed participants (8 male and 8 female students) were presented with cartoon faces expressing emotions ranging from extremely positive to extremely negative. A forced-choice paradigm was used in which the participants were asked to rate the faces as either positive or negative. Compared to men, women rated faces more positively, especially in response to right visual field presentations. Women rated neutral and mildly positive faces more positively in the right than in the left visual field, whereas men rated these faces consistently across visual fields. Handedness did not affect the ratings of emotion. The data suggest a positive emotional bias of the left hemisphere in women. 相似文献

We used a spatial negative priming (SNP) paradigm to examine visual selective attention in infants and adults using eye movements as the motor selection measure. In SNP, when a previously ignored location becomes the target to be selected, responses to it are impaired, providing a measure of inhibitory selection. Each trial consisted of a prime and a probe, separated by 67, 200, or 550 ms interstimulus intervals (ISIs). In the prime, a target was accompanied by a distractor. In the probe, the target appeared either in the location formerly occupied by the distractor (ignored repetition) or in another location (control). Adults exhibited the SNP effect in all three ISI conditions, producing slower saccade latencies on ignored repetition versus control trials. The SNP effect obtained for infants only under 550 and 200 ms ISI conditions. These results suggest that important developments in visual selection are rooted in emerging inhibitory mechanisms. 相似文献
In face-to-face conversation speech is perceived by ear and eye. We studied the prerequisites of audio-visual speech perception by using perceptually ambiguous sine wave replicas of natural speech as auditory stimuli. When the subjects were not aware that the auditory stimuli were speech, they showed only negligible integration of auditory and visual stimuli. When the same subjects learned to perceive the same auditory stimuli as speech, they integrated the auditory and visual stimuli in a similar manner as natural speech. These results demonstrate the existence of a multisensory speech-specific mode of perception. 相似文献
Critics of genetic discourse are concerned that deterministic and discriminatory views of genetics are increasingly becoming
adopted. These views argue that current genetic discourse becomes a source of power whereby powerful institutions harm people
with so-called “bad” genes. This essay argues that current analyses of the power of genetics discourse are grounded in an
improper reading that disempowers patients. Deploying Michel Foucault's concept “care of the self,” this essay claims that
genetics discourse is better understood as a way that patients take on power through rhetoric rather than a force that has
power over patients. Through a close reading of the “My Family Health Portrait” program, this paper argues that patients experience
a process of “subjection” wherein they become agents of and objects of genetics discourse both. This alternative mode of analyzing
the power of genetics discourse has implications for our collective understanding of the operations of the care of the self
and the uses of genetic information that we propose. 相似文献
This paper describes how the Electrical and Computer Engineering Department at South Dakota School of Mines and Technology
has chosen to integrate ethics into their curriculum. All university freshmen engineering students are introduced to ethics
through the presentation of ethical dilemmas. During this exercise, students are forced to argue both sides (‘for’ and ‘against’)
of a hypothetical ethical engineering dilemma. It provides a setting for great discussion with the desired outcome that they
learn to carefully analyze a situation before they draw conclusions. In the sophomore year, students are introduced to methods
to use the fundamental principles, the fundamental canons, and the suggested guidelines for use with the fundamental canons
of ethics when analyzing appropriate action to be taken when confronted with ethical dilemmas. We currently use the ‘sophomore’
method for seniors because the sequencing is just beginning. Next year the seniors will do more indepth analysis of ethical
case studies.
