Procurement of organs from non-heart-beating cadaver donors raises concerns. Standards for optimal patient care during withdrawal of life-sustaining therapy are evolving and continue to be debated and studied. Consensus on specific procedures and methods has not been attained, however, and protocols for the procurement of organs from patients following the withdrawal of life-sustaining therapies may compromise the evolving standards and harm the patient and the attendant family. In addition, there is little evidence to suggest that such protocols will significantly increase the number of organs procured. "Non-heart-beating cadaver" protocols that do not give comprehensive attention to optimal patient/family care at the time of withdrawal of life-sustaining therapy ought not to be endorsed. 相似文献

This paper surveys the process approach literature with an emphasis on higher level cognitive functions like attention and concentration, learning and memory, and problem solving and executive functioning. In particular, it discusses organizational strategies and kinds of errors found on a variety of tests as well as behavioral, situational, and interpersonal issues as they relate to test procedures. It critiques the process approach and suggests future directions. 相似文献

This paper tests the hypothesis that contemporary global and globalised religion as exemplified in the Chicago ‘Parliament of the World's Religions’ of 1993 may be regarded as a resource which is central, rather than marginal to current human concerns in a threatened world. The paper is structured as follows. First, a short personal narrative gives some sense of what happened at the Parliament, and how this affected one of those present. Second, as a means of conveying the scale of the meeting, a brief content analysis and interpretation of the programme shows how (within certain limits) collaboration was made possible. Third, three insights are drawn from current sociology that facilitate an informed, albeit preliminary, evaluation of the Parliament as emancipatory event. These are: i) recent globalisation theory of the world system (Roland Robertson and Peter Beyer); ii) differentiation in a social reality understood as an “economy of signs and space”; (Scott Lash and John Urry); and in) the search for “meta‐theory”; in the “condition of post‐modernity”; (David Harvey). Fourth, some implications of the analysis and interpretation are drawn out which suggest that religion can be understood as a differentiated global resource, an ambiguous, yet dynamic form of ‘cultural capital’ of vital import in an era of post‐materialist value formation. Fifth, in conclusion, it is argued that thus understood the globalised religion represented by the 1993 ‘Parliament of the World's Religions’ has wider implications for the study of contemporary religion and forms of religiosity. Religion returns from the theoretical and cultural periphery (a marginalisation promoted by traditional secularisation theory) into a close relation to the core issues of our time. This is an optimistic interpretation of an event, the significance of which, in the opinion of this writer, should not be underestimated in the evaluation of religion as global resource. 相似文献

The human person makes great demands on the physician and calls for unique attention. Hence the doctor-patient relationship calls for the highest ideals of kindness, patience, trustworthiness, generosity and skill. The Catholic physician brings to these demands a specific meaning: ministering to the sick is to see Christ in them and to show Him to them. 相似文献

Recent speech research has begun to evaluate the internal structure of categories. In one such study, Kuhl (1991) found that discrimination was poorer for vowel stimuli that were more representative of the category (prototype, or P, set) than it was for less representative stimuli (nonprototype, or NP, set). This finding was interpreted as indicating that a category prototype may function as a “perceptual magnet,” effectively decreasing perceptual distance, and thus discriminability, between stimuli. The present study examines the function of prototypes in a musical category—another natural, but nonspeech category. Paralleling the Kuhl study, representative (P) and less representative (NP) sets of major triad stimuli were constructed, based on equal temperament. Musically experienced subjects rated the stimuli in each set for goodness as a major triad, with the highest rated stimulus serving as a prototype standard for a subsequent discrimination task. Results from the discrimination task demonstrated better performance in the P context than in the NP context. The current nonspeech results indicate that a prototype functions as an anchor rather than a magnet. In addition to providing a natural, nonspeech standard for comparison with speech findings, the results provide some important insights into the nature of musical categories. 相似文献

Although the eyes and the heart serve very different purposes, each receives autonomic innervation. Capitalizing on recent
theoretical and technological innovations in the understanding and assessment of oculomotor and cardiovascular behavior, three
experiments measured behavioral covariation between the oculomotor and cardiovascular systems. Measures of dark focus and
dark vergence indexed oculomotor tone, and the spectral decomposition of variations in heart rate indexed cardiovascular control
mechanisms. In Experiment 1, individual differences in cardiovascular parameters could predict individuals’ dark vergence
(R2=.806) but not their dark focus (R2=.404). In Experiment 2, the same parameters were measured from subjects who experience either panic attacks (n=11) or blood phobia (n=9). Heart rate was positively correlated with dark vergence and the two subject groups were separable based on both oculomotor
and cardiovascular variables. Using a within-subjects approach, Experiment 3 found that both dark vergence and dark focus
tended to be nearer during sympathetic dominance of the heart than during parasympathetic dominance, within-subjects variations
in cardiovascular parameters could predict dark focus, and between-subjects variations in interbeat intervals could predict
dark vergence. Shared patterns of autonomic activation may be responsible for this eye-heart link. 相似文献

Cortisol can be used to indicate stress level as well as to monitor certain disease states. Although cortisol can be sampled from blood and urine, saliva sampling has decided advantages. Unfortunately, whole saliva contains a number of substances that can metabolize or bind with cortisol, potentially confounding analysis and quantitation. We introduce a semipermeable pouch that accumulates a contaminant-free salivary ultrafiltrate, thereby overcoming a number of the problems encountered with whole saliva. In three studies, we demonstrate accuracy and utility of the device for cortisol determination: (1) in an artificial medium, 60%–77% of the cortisol was recovered in the ultrafiltrate; (2) in vivo, ultrafiltrate cortisol correlated highly with whole-saliva cortisol collected under ideal conditions; and (3) ultrafiltrate cortisol evinced positive relationships with depression and cigarette use, consistent with studies in the literature. We conclude that this device and saliva-filtering technologies in general are useful in applications requiring quantitation of cortisol. 相似文献

The Emergency Psychiatry Nursing Assessment Report Framework (EP Nurse) is designed to guide the nurse through the interview-and-reporting process, and to produce a report of the nursing evaluation in emergency psychiatry in 5–10 min. Input includes identifying information, presenting complaints, substance-use history, medical history and vitals, psychiatric medications, treatment history, history of mental illness, last hospitalization, family history of mental illness, nursing diagnosis, and nursing intervention. EP Nurse is intended to be used by licensed nurses familiar with nursing assessment in emergency psychiatry. It is suitable for adult patients. 相似文献

Although infants have the ability to discriminate a variety of speech contrasts, young children cannot always use this ability in the service of spoken-word recognition. The research reported here asked whether the reason young children sometimes fail to discriminate minimal word pairs is that they are less efficient at word recognition than adults, or whether it is that they employ different lexical representations. In particular, the research evaluated the proposal that young children’s lexical representations are more “holistic” than those of adults, and are based on overall acoustic-phonetic properties, as opposed to phonetic segments. Three- and four-year-olds were exposed initially to an invariant target word and were subsequently asked to determine whether a series of auditory stimuli matched or did not match the target. The critical test stimuli were nonwords that varied in their degree of phonetic featural overlap with the target, as well as in terms of the position(s) within the stimuli at which they differed from the target, and whether they differed from the target on one or two segments. Data from four experiments demonstrated that the frequency with which children mistook a nonword stimulus for the target was influenced by extent of featural overlap, but not by word position. The data also showed that, contrary to the predictions of the holistic hypothesis, stimuli differing from the target by two features on a single segment were confused with the target more often than were stimuli differing by a single feature on each of two segments. This finding suggests that children use both phonetic features and segments in accessing their mental lexicons, and that they are therefore much more similar to adults than is suggested by the holistic hypothesis. 相似文献
