Cognition theories describe the social with terms like language, interaction or culture, whose theoretical status has also been discussed in modern sociology. These concepts are not well-positioned to understand the emergence and autonomy of social orders. Sociological theory of self-referential systems can be useful to reconstruct the bottom-up process which contributes to the emergence of the social as communication as well as to describe the way in which society exerts downward causation upon cognitive phenomena. The core of this theory is the systemic category of meaning as a shared horizon for psychic and social systems.  相似文献

从系统论看肿瘤的生物靶向性治疗   总被引:2,自引:0,他引:2  
肿瘤的生物靶向性治疗是恶性肿瘤治疗的新方法,其试图通过在基因水平上调节与肿瘤发生、发展有密切联系的生命物质来达到治愈肿瘤的目的。但临床运用中,生物靶向性治疗的疗效与我们的想象相去甚远。本文运用系统论的观点,分析目前生物靶向性治疗中存在的问题及寻求可能解决的方法。  相似文献

Griffiths and Tenenbaum (2006) asked individuals to make predictions about the duration or extent of everyday events (e.g., cake baking times), and reported that predictions were optimal, employing Bayesian inference based on veridical prior distributions. Although the predictions conformed strikingly to statistics of the world, they reflect averages over many individuals. On the conjecture that the accuracy of the group response is chiefly a consequence of aggregating across individuals, we constructed simple, heuristic approximations to the Bayesian model premised on the hypothesis that individuals have access merely to a sample of k instances drawn from the relevant distribution. The accuracy of the group response reported by Griffiths and Tenenbaum could be accounted for by supposing that individuals each utilize only two instances. Moreover, the variability of the group data is more consistent with this small-sample hypothesis than with the hypothesis that people utilize veridical or nearly veridical representations of the underlying prior distributions. Our analyses lead to a qualitatively different view of how individuals reason from past experience than the view espoused by Griffiths and Tenenbaum.  相似文献

There are a number of proposals as to exactly how reasons, ends and rationality are related. It is often thought that practical reasons can be analyzed in terms of practical rationality, which, in turn, has something to do with the pursuit of ends. I want to argue against the conceptual priority of rationality and the pursuit of ends, and in favor of the conceptual priority of reasons. This case comes in two parts. I first argue for a new conception of ends by which all ends are had under the guise of reasons. I then articulate a sense of rationality, procedural rationality, that is connected with the pursuit of ends so conceived, where one is rational to the extent that one is motivated to act in accordance with reasons as they appear to be. Unfortunately, these conceptions of ends and procedural rationality are inadequate for building an account of practical reasons, though I try to explain why it is that the rational pursuit of ends generates intuitive but misleading accounts of genuine normative reasons. The crux of the problem is an insensitivity to an is-seems distinction, where procedural rationality concerns reasons as they appear, and what we are after is a substantive sense of rationality that concerns reasons as they are. Based on these distinct senses of rationality, and some disambiguation of what it is to have a reason, I offer a critique of internalist analyses of one’s reasons in terms of the motivational states of one’s ideal, procedurally rational self, and I offer an alternative analysis of one’s practical reasons in terms of practical wisdom that overcomes objections to related reasons externalist views. The resulting theory is roughly Humean about procedural rationality and roughly Aristotelian about reasons, capturing the core truths of both camps.

为了增强对脑室系统的血管畸形的认识,回顾性总结24例脑室系统的血管畸形的基本临床资料。结果显示,除1例静脉畸形外,其余23例均接受手术,21例全切,2例部分切除,病理证实海绵状血管瘤13例,AVM10例,其中死亡1例。提示脑室系统血管畸形发病率低,出血及脑积水多见,手术切除是海绵状血管瘤和AVM的最佳选择,而静脉畸形应予保留。  相似文献

我国艾滋病患者持续上升。艾滋病不仅损害了人们的躯体健康,也同时损害了人们的心理健康,引发心理危机。观察300例患者发现:抑郁症41.3%、焦虑症31.4%、报复心理20.0%、麻木8.3%。艾滋病的防治不仅仅是治疗肌体病痛的问题,还应该治疗患者的心理问题。因此运用系统论对艾滋病人心理问题中的相关问题进行探索和剖析,动员患者及全社会行动起来,才能达到对艾滋病的有效控制。  相似文献

心理咨询与心理治疗效果的关键在于心理咨询与心理治疗师自身的特质,而非理论技巧。因此,心理咨询与心理治疗师在心理咨询与治疗的过程中,会非常直接、深刻和迅速地影响当事人的生活。通过对我国心理咨询师健康发展之要素的探讨,提出心理咨询师的培养应逐步走向正规专业教育和训练途径;同时关注心理咨询师自己的个人成长,健全督导制度是预防心理咨询师的职业耗竭,也是我国心理咨询业健康发展的根本保障。  相似文献
