对微创脊柱外科发展历程的思考

微创脊柱外科是现代脊柱外科发展的必然趋势。近几十年来,微创技术不断革新,微创理念也逐渐深入人心。在取得了巨大成就的同时还有许多问题值得我们去思考和探索。我们不仅应注重微创技术的创新和应用,更要注意应用微创理念,做到二者的有机统一。     

Differential effects of mindful breathing, progressive muscle relaxation, and loving-kindness meditation on decentering and negative reactions to repetitive thoughts

Decentering has been proposed as a potential mechanism of mindfulness-based interventions but has received limited empirical examination to date in experimental studies comparing mindfulness meditation to active comparison conditions. In the present study, we compared the immediate effects of mindful breathing (MB) to two alternative stress-management techniques: progressive muscle relaxation (PMR) and loving-kindness meditation (LKM) to test whether decentering is unique to mindfulness meditation or common across approaches. Novice meditators (190 female undergraduates) were randomly assigned to complete one of three 15-min stress-management exercises (MB, PMR, or LKM) presented by audio recording. Immediately after the exercise, participants completed measures of decentering, frequency of repetitive thoughts during the exercise, and degree of negative reaction to thoughts. As predicted, participants in the MB condition reported greater decentering relative to the other two conditions. The association between frequency of repetitive thought and negative reactions to thoughts was relatively weaker in the MB condition than in the PMR and LKM conditions, in which these two variables were strongly and positively correlated. Consistent with the construct of decentering, the relative independence between these two variables in the MB condition suggests that mindful breathing may help to reduce reactivity to repetitive thoughts. Taken together, results help to provide further evidence of decentering as a potential mechanism that distinguishes mindfulness practice from other credible stress-management approaches.     

THOUGHT EXPERIMENTS

Abstract: This article seeks to explain how thought experiments work, and also the reasons why they can fail. It is divided into four sections. The first argues that thought experiments in philosophy and science should be treated together. The second examines existing accounts of thought experiments and shows why they are inadequate. The third proposes a better account of thought experiments. According to this account, a thought experimenter manipulates her worldview in accord with the “what if” questions posed by a thought experiment. When all necessary manipulations are carried through, the result is either a consistent model or a contradiction. If a consistent model is achieved, the thought experimenter can conclude that the scenario is possible; if a consistent model cannot be constructed, then the scenario is not possible. The fourth section of the article uses this account to shed light on the circumstances in which thought experiments fail.     

THE VARIETY OF PANENTHEISMS

Abstract. In this article I review the efforts of eighteen scientists and theologians, recorded in this book, to describe the relation of God to the universe during a conference sponsored by the John Templeton Foundation at Windsor Castle in 2001. Theologians from several branches of Christian faith articulate their understanding of panentheism, revealing a considerable diversity. I deal with each author in relation to six issues: the way God acts, how God's intimate relation to the world is to be described, the relation of God to spacetime, whether God is dependent upon the world, what type of language is used, and the problem of dipolar panentheism. I identify significant differences between these authors, suggest where fruitful dialogue is possible, and distinguish between intelligibility and plausibility in comparing dipolar panentheism with other types.     

When effortful thinking influences judgmental anchoring: differential effects of forewarning and incentives on self‐generated and externally provided anchors

Two experiments examined the impact of financial incentives and forewarnings on judgmental anchoring effects, or the tendency for judgments of uncertain qualities to be biased in the direction of salient anchor values. Previous research has found no effect of either manipulation on the magnitude of anchoring effects. We argue, however, that anchoring effects are produced by multiple mechanisms—one involving an effortful process of adjustment from “self‐generated” anchors, and another involving the biased recruitment of anchor‐consistent information from “externally provided” anchors—and that only the former should be influenced by incentives and forewarning. Two studies confirmed these predictions, showing that responses to “self‐generated” anchors are influenced by both incentives and forewarnings whereas responses to “externally provided” anchors are not. Discussion focuses on the implications of these effects for debiasing efforts. Copyright © 2005 John Wiley & Sons, Ltd.

Multiple Realizability Intuitions and the Functionalist Conception of the Mind

A popular argument supporting functionalism has been what is commonly called the “multiple realizability” argument. One version of this argument uses thought experiments designed to show that minds could be composed of different types of material. This article offers a metaphilosophical analysis of this argument and shows that it fails to provide a strong case for functionalism. The multiple realizability argument is best understood as an inference‐to‐the‐best‐explanation argument, whereby a functionalist account of our mental concepts serves to explain our multiple realizability intuitions. I show that the argument is inadequate because alternative accounts of our mental concepts exist that provide equally plausible explanations for these intuitions. Moreover, in the case of our qualia concepts, a nonfunctionalist account explains several other intuitions that functionalism cannot explain. Thus, despite its popularity, the intuition‐based version of the multiple realizability argument is a poor reason for accepting functionalism.     

Philosophy in the Act: The Socio-Political Relevance of Mamardašvili’s Philosophizing

Although topics in social and political philosophy might not be the first to associate with Mamarda?vili, it is argued in this paper that key concepts in his thought, viz. the concepts of form, thought, and culture come together, in the 1980s in particular, in a notion of civil society that goes deeper than that of many of his contemporaries. The relevance of his philosophy at this point is intensified by the specific nature of Soviet philosophical culture, but, it is argued, extends well beyond that, fully justifying his honorary title of “Georgian Socrates”.     

Three Arguments For Scientific Freedom

The principle of scientific freedom is usually taken forgranted; few attempts have been made to justify it systematically. The present paper discusses three “classic” arguments, which are used to justify this principle. However, it will become clear that (a) each argument refers to a different understanding of science and therefore justifies a different type of science, and that (b) each of them is based on assumptions which are not always consistent with the social reality of scientific research; the profound changes science has undergone since its inception are not sufficiently taken into account.     

The Christology of St Anthony of Padua: content and method

In 1946 St Anthony of Padua (1195–1231) was declared a Doctor of the Church, recognised for his profound learning. Whereas much has been written about St Anthony, very little of it concerns his profound learning – and so it is not inappropriate to ask wherein this learning lies. Reading St Anthony reveals Christological concerns to be at the heart of his work and in this paper the author explores and clarifies his position. However, anyone looking for new and exciting Christological insights is likely to be disappointed, for St Anthony is entirely orthodox and traditional, although we should not only consider the content of his work, but his ‘method’ too. The way that the saint presents doctrine, and the inferences he draws from it, has much to be commended. Indeed, St Anthony may well be contrasted with those modern theologians who, it has been suggested, have rather lost track of what it is they are really doing.
