The author reviews the arguments made by Mark Hanson, James Keenan, S.J., and Joel Shuman in this issue. In the first section, she argues that they offer a significant contribution toward an understanding of the inner logic of a new trend in contemporary medicine, genetic engineering. However, she criticizes the authors for relying excessively on procedural guidelines and for failing to bring the practical realities of medicine and technology to bear on theory. She argues that more concrete guidelines, which are ultimately grounded in a Christian conception of the person and on the commandment to love, are necessary. Writing from the Roman Catholic perspective, the author argues that the distinction between genetic enhancement and gene therapy is essential, despite the criticisms which have been offered of this distinction. Understanding this distinction will be critical for identifying as licit only those forms of genetic manipulation which respect the dignity of the human person. 相似文献

We present a framework for machine implementation of families of non-classical logics with Kripke-style semantics. We decompose a logic into two interacting parts, each a natural deduction system: a base logic of labelled formulae, and a theory of labels characterizing the properties of the Kripke models. By appropriate combinations we capture both partial and complete fragments of large families of non-classical logics such as modal, relevance, and intuitionistic logics. Our approach is modular and supports uniform proofs of soundness, completeness and proof normalization. We have implemented our work in the Isabelle Logical Framework. 相似文献

Our 51-year old patient developed low back pain and an increase of tonus mainly in the left limb and trunk muscles. Microscopic examination of the muscles and electronmicroscopic examination of the sural nerve and that of the gastronemic muscle did not show any specific deviation. On the basis of spontaneous activity observed during EMG examination, protracted motor activity of great amplitude when moved passively, as well as characteristic clinical symptoms and the disease process Stiff-man syndrome was diagnosed. Considering literature data, we tried applying diazepam (Seduxen and Rivotril)-presumably increasing the praesynaptic inhibition and affecting the reticular system of the brain stem-, as well as GABA medicaments (Lioresal and Depakine) increasing synaptic transport. By giving Seduxen, Rivotril and Baclofen simultaneously a lasting remission of symptoms could be reached. Applying Depakine in combination with the above medicines proved ineffective, presumably because of synergetic side effects. 相似文献

Contributions to factor analysis of dichotomous variables 总被引:5,自引:0,他引:5

A new method is proposed for the factor analysis of dichotomous variables. Similar to the method of Christoffersson this uses information from the first and second order proportions to fit a multiple factor model. Through a transformation into a new set of sample characteristics, the estimation is considerably simplified. A generalized least-squares estimator is proposed, which asymptotically is as efficient as the corresponding estimator of Christoffersson, but which demands less computing time.This research was supported by the Bank of Sweden Tercentenary Foundation under project Structural Equation Models in the Social Sciences, project director Karl G. Jöreskog. 相似文献

Conceptual system as a cognitive-developmental variable in personality has been assumed to relate to different cognitions of self and others and of interpersonal relations at each developmental stage. The assumed relationship between conceptual system and some personality variables was studied in a group of students (N = 85). The “This-I-Believe” test (TIB) [Harvey, O. J. System structure, adaptability and creativity. In O. J. Harvey (Ed.), Experience, structure, and adaptability. New York: Springer, 1966.] for assessing the developmental stage of the conceptual system was administered together with personality scales for traits assumed important in socialization. A modified TIB scoring procedure was used. Highly significant differences in personality were obtained by a MANOVA, using conceptual system for classification. One dimension accounted for discrimination. Measures assumed to relate to sensitivity for and conformity to a social environment contributed most to the discrimination. 相似文献

Searle's Chinese Room was supposed to prove that computers can't understand: the man in the room, following, like a computer, syntactical rules alone, though indistinguishable from a genuine Chinese speaker, doesn't understand a word. But such a room is impossible: the man won't be able to respond correctly to questions like ‘What is the time?’, even though such an ability is indispensable for a genuine Chinese speaker. Several ways to provide the room with the required ability are considered, and it is concluded that for each of these the room will have understanding. Hence, Searle's argument is invalid. 相似文献

A computerized version of the Tower of Hanoi with a new form of administration was administered to two different groups, 15 men and 22 women, who were university students reporting normal psychological histories, and 24 traumatically brain-injured patients (20 men and 4 women). Scores on this test for both groups can be interpreted as an index of ability to solve problems and of learning strategies. Men and women scored differently on the task, i.e., women used different strategies than men to solve problems. 相似文献

40 and 48 subjects participated in two separate experiments aimed at reproducing the subliminal psychodynamic activation (SPA) phenomenon and taking into account the major methodological critique by Fudin (1986, 1990). Subjects were first exposed either to a full or one of all possible partial symbiotic messages and then to their anagram equivalents. Confounding and irrelevant influences were controlled; the results indicate that only the full symbiotic message improved motor performance. This strongly suggests that subjects encode the meaning of the full message and supports an interpretation in terms of an alleviation of an internal symbiotic conflict leading to a state of calmness conducive to improved motor performance. 相似文献
