Rights to do wrong are not necessary even within the framework of interest-based rights aimed at preserving autonomy (contra Waldron, Enoch, and Herstein). Agents can make morally significant choices and develop their moral character without a right to do wrong, so long as we allow that there can be moral variation within the set of actions that an agent is permitted to perform. Agents can also engage in non-trivial self-constitution in choosing between morally indifferent options, so long as there is adequate non-moral variation among the alternatives. The stubborn intuition that individuals have a right to do wrong in some cases can be explained as stemming from a cautionary principle motivated by the asymmetry between the risk of wrongly interfering and that of refraining from interfering. 相似文献

Stress can precipitate major depression and other disorders linked to hippocampal shrinkage. It is hypothesized but not established that treatment of these disorders reverses and prevents the hippocampal changes. Dendritic retraction of individual neurons might in concert with other pathophysiological events contribute to the shrinkage phenomenon. Animal studies have shown that various stress paradigms can induce dendritic retraction in the CA3 pyramidal neurons of the hippocampus. Since electroconvulsive treatment is the most effective treatment in humans with major depression, we investigated whether repeated electroconvulsive stimulations (ECSs) could influence such changes in stressed rats. Furthermore, we investigated whether ECSs per se could influence neuronal branching and total length of the CA3 hippocampal neuronal dendritic tree in normal rats. Rats were stressed using the 21-day 6 h daily restraint stress paradigm. The study shows that stress caused remodelling of the pyramidal neurons by significantly reducing the number of dendritic branch points and total length of the apical dendritic tree. Concomitant administration of ECSs prevented these effects. ECSs had no effect on pyramidal neuron dendrites in normal rats. 相似文献

THE CONTROL OF BIAS IN RATINGS: A THEORY OF RATING 总被引:2,自引:0,他引:2
Based on several years of research and a careful analysis of the rating process Wherry developed a theory of rating. An accurate rating is seen as being a function of three major components: Performance of the ratee, observation of that performance by the rater, and the recall of those observations by the rater. Cast in a mold of classical psychometric theory each of these components is seen as consisting of a systematic portion and a random portion. The systematic portion of each component is further broken down. The performance of the ratee is a combination of true ability or aptitude for the job and the influence of the environment. What the rater observes is a function the performance of the ratee and bias of observation and what the rater recalls is a result of those observations combined with a bias of recall. The development of the theory of rating unfolds by defining the various factors that affect each of these components in a series of linear equations. Various theorems and corollaries are proposed which should lead to a maximization of the true ability component of the ratee and minimize environmental influence and the bias and error components. The theorems and corollaries suggest testable hypotheses for the researcher in performance evaluation. 相似文献

Dictionary definitions are often used in education and in computerized databases for processing natural language, but their accuracy as models of word meaning has not been carefully evaluated. An experiment involving fourth graders and adults measured the efficacy of dictionary definitions in marking distinctions in sense and found them to be very poor for children, but fairly helpful for adults. A second experiment compared dictionary definitions to definitions written by college students who had sorted sets of sentence citations, and found both moderately effective in teaching word use. Good definitions were produced less often for high-frequency words than for low-frequency words, given equivalent numbers of citations, suggesting that sentences using high-frequency words are less informative overall. Also, the more citations available to the definition writer, the better the definition was in teaching word use, suggesting that information about word meaning is cumulative and describable.This research was partially supported by grants from the Spencer and Sloan Foundations to George A. Miller. 相似文献

In this article, I develop a higher-order interpretation of Leibniz's theory of consciousness according to which memory is constitutive of consciousness. I offer an account of Leibniz's theory of memory on which his theory of consciousness may be based, and I then show that Leibniz could have developed a coherent higher-order account. However, it is not clear whether Leibniz held (or should have held) such an account of consciousness; I sketch an alternative that has at least as many advantages as the higher-order theory. This analysis provides an important antecedent to the contemporary discussions of higher-order theories of consciousness. 相似文献
