脑及其自我先天本能和后天驱动力的神经生物化学观念

这本专著总结了作者多年来最重要的研究成果。研究表明，人的大脑皮层具有获得驱动力的独特能力．正是这种能力创造了人类社会，并促使人类社会不断进化。作者认为，人类社会目前还处于反复实验的发展阶段，但其最终必将由现在的不可知状态逐渐过渡到理性指导的平衡状态。通过对获得性驱动力的特殊分析及以前曾认为不可知的脑机理的发现，作者对社会生活的发展及艺术、科学的起源给出了合理的生理学解释。本书的目的是要论证即使在脑及其自我的关系中，自然规律仍然是简单的，而不是不可知的。

世界文化和不可知论的政见——一个致力于跨文化融洽交流的计划

就世界文化课程内容的具体设置,及联合大学与传媒以更好地实现课程积极目标等诸问题进行探讨.通过多层次的论证强调指出人们始终持有相异或相冲突的宗教、哲学以及意识形态,尚没有一种普世真理足以使世间所有人心悦诚服.即便是广泛接受和运用中的科学知识,其发展亦受阻于人类本身的局限而不可确定.尽管科学在前沿问题研究上竞争激烈,也仍然无法回答和消除所有的问题和差异.因此,从全球或泛人类立场观之,人类现有的知识与理解能力具有不确定和不完整的特点,而这样的特点浸透在所有的具体文化信仰之中.认识到共同局限性的人们--尤其是政界的领导人--亟需摒弃极端的文化分离思想,以更宽容理解的心态思考和行动,这样才能避免不同民族及不同国家间的不断冲突和互相伤害.     

北祁连山榴辉岩锆石SHRIMP定年及其构造意义

应用阴极发光和离子探针技术, 对北祁连山高压变质带两个榴辉岩样品中的锆石进行了结构和形态学观察以及原位U-Pb定年. 所获得的年龄值分别为463 ± 6 和468 ± 13 Ma, 代表了本区榴辉岩相变质时代. 这是北祁连山加里东期高压变质作用的最早记录, 可能代表了大洋板块俯冲进入上地幔经受榴辉岩相变质的时间.
