Brain activation detection by neighborhood one-class SVM

Brain activation detection is an important problem in fMRI data analysis. In this paper, we propose a data-driven activation detection method called neighborhood one-class SVM (NOC-SVM). Based on the probability distribution assumption of the one-class SVM algorithm and the neighborhood consistency hypothesis, NOC-SVM identifies a voxel as either an activated or non-activated voxel by a weighted distance between its near neighbors and a hyperplane in a high-dimensional kernel space. The proposed NOC-SVM are evaluated by using both synthetic and real datasets. On two synthetic datasets with different SNRs, NOC-SVM performs better than K-means and fuzzy K-means clustering and is comparable to POM. On a real fMRI dataset, NOC-SVM can discover activated regions similar to K-means and fuzzy K-means. These results show that the proposed algorithm is an effective activation detection method for fMRI data analysis. Furthermore, it is stabler than K-means and fuzzy K-means clustering.     

“过分自信”的研究及其跨文化差异

“过分自信”是一种偏离校准,是指人们关于一般知识问题的概率判断通常以某种方式偏离校准,这种偏离都偏高。跨文化系列研究表明：面对常识和概率判断问题,集体主义文化成员（如中国人）比个体主义文化成员（如美国人）更过分自信。文章在简要回顾“过分自信”研究的基础上,对“过分自信”的跨文化差异及原因进行了比较详细地介绍,并对“过分自信”跨文化差异研究的进一步发展和实际应用进行讨论。冀对以往的研究做初步的归纳和总结,促进决策领域中跨文化比较方面的研究得到进一步发展     

平面香水广告版面设计的眼动研究

本研究以EyeLinkⅡ型眼动仪探讨被试在观看香水广告时的眼动特征。实验设计为4(香水瓶位置:左上角、右上角、左下角、右下角)×3(背景图案:人物、广告词、风景)×2(兴趣区:香水、背景)的被试内设计。结果发现:(1)当香水瓶位于广告的下半部分时能够吸引消费者更多的注意;(2)当以人物为背景图案时,被试对位于广告左下角的香水瓶的注意更多;当以广告词为背景图案时,被试对位于广告的左上角的香水瓶的注意更多;(3)被试对香水广告版面设计时背景图案为风景的香水广告的喜爱甚于人物(名人或模特)和广告词。     

Buddhist Thought and Several Problems in the World Today

Buddhism has not only produced an influence upon the ancient world culture but is also playing an important role in world affairs today. This article analyzes several important problems in the world today: world peace, disarmament, economic justice, human rights, environmental protection, and universal cooperation in world problem solving. The writer holds that, to solve these problems, we should study Buddhist theory and get some helpful ideas from it. Translated from Beida Journal of Philosophy, Vol. 5, Special Issue, April 2004     

There are no Degrees in a Bodhisattva's Compassion

This paper is to argue that there are no degrees in a Bodhisattva's compassion and also to explore the Western account of compassion, which suggests that there are degrees in our compassion. After analyzing and comparing both positions, I affirm that they are opposite views.     

佛教与婆罗门教善恶观念比较

佛教与婆罗门教是古代印度的两个主要宗教派别。它们的善恶观念是各自理论体系中的重要组成部分。两教的此类观念虽然有明显不同,但都与古代印度圣典吠陀和奥义书有渊源关系。佛教和婆罗门教各自的善恶观念都有不同层次的划分。在后来的发展中,两教的善恶观念有很大的趋同性,它们相互影响,彼此吸收对方思想。两教中的一些基本层次的善恶观念的内容有大量是相同的,较高层次的善恶观念虽有不同,但同样强调智慧解脱。这方面的思想对古代印度系统宗教哲学的形成起了促进作用,在世界文化发展史上占有重要地位。     

印度古代宗教中的神的观念

本文对印度古代哲学中的神的观念进行了专门研究.作者对印度最早的宗教历史文献--吠陀中的神的观念的主要形态进行了描述,对印度社会中影响最大的婆罗门教(印度教)的神的观念进行了探讨,并对神在印度宗教哲学中的地位进行了分析.认为印度的宗教在东方文化中占有显要的地位,而古代印度人的神的观念又是其宗教理论中的基本内容.     

对表征方式与内容类别影响THOG问题判定的再考察

用独立组实验设计重新研究了“内容类别”与“表征方式”两个因素对被试判定THOG问题的作用。结果表明．主词一致的表征方式只对被试正确解决具体内容的THOG问题具有促进作用。主词是否一致对被试正确解决抽象内容的THOG问题并没有显著影响。     

The Undesirable & the Adesirable

The guise of the good thesis can be understood as an attempt to distinguish between human motivations that are intelligible as desires and those that are not. I propose, first, that we understand the intelligibility at stake here as the kind necessary for the experience of reactive attitudes, both negative and positive, to the behavior and motivations of an agent. Given this, I argue that the thesis must be understood as proposing substantive content restrictions on how human agents perceive objects of their desires; it cannot be a purely formal constraint. Moreover, while proponents of the guise of the good thesis who posit substantive content restrictions on human desire are right to do so, they are mistaken to claim that we always desire the apparently good. Instead, I propose a different limit: the naturally attractive. This alternative to the guise of the good thesis nonetheless captures the compelling idea that human desires are intelligent, quasi‐perceptual responses to the world.     

自动思维及归因方式对抑郁症作用的多因素分析

目的：探讨抑郁症患者治疗前后自动思维、应付方式变化对抑郁严重程度变化的影响及其相互作用。方法：对97例抑郁症患者分别在其入、出院时进行测评,测评工具包括自评抑郁量表、自动思维问卷和归因方式问卷。此外对100例正常对照亦进行上述测评,其中29例在15—20天后重测。结果：自动思维问卷得分、归因方式问卷得分的logistic回归分析、路径分析表明,自动思维、对正性事件的整体性维度的归因方式对抑郁程度的影响有显著作用,自动思维的变化对SDS的变化的直接影响最大(路径系数为0．572),归因方式中正性事件整体性归因的变化为其次(路径系数为一0．193),而自动思维的变化与归因方式中正性事件整体性归因的变化的相互影响较小(路径系数为-0．188)。结论：自动思维、对正性事件的整体性维度的归因方式对抑郁严重程度有显著影响。
