音乐与科学的不解缘

音乐是声音的艺术,它与声音科学的关系最为密切。声乐和器乐都与许多门类的科学相关。音乐具有启迪创造思维,开发创造力的功能。音乐学习能提高儿童的空间推理能力。通过音乐的物理作用、社会作用和情绪作用可以达到治疗人体疾病的目的。音乐还与动物和植物的生态密切相关。植物经络学说和植物控制系统的理论与实践,揭示了音乐农学将造福人类的光明前景。     

思维科学视角下的文理兼修——谈如何培养工科大学生的形象思维能力

形象思维和逻辑思维是人们普遍关注的两种基本思维形式,但长久以来却存在按文、理截然两分的偏误。本文在揭示将“文科思维”与“理科思维”截然分开的片面性基础上,重点探讨工科大学生加强形象思维能力培养的途径和方法。     

论文明的发展趋势——生态文明

从属于地球共同体的人类文明走过了原始文明、农业文明,又演绎出今天的现代全球文明。现代文明的缺陷引起地球共同体终结的危机。因此人类文明需要进入新的发展过程,而走向生态文明就是人类和地球共同体的未来,这需要克服实证科学语言所具有的单一性,以东方占优势的类比思维来弥补西方实证科学逻辑思维的不足。无论是东方文明还是西方文明,都有着相互的关联。西方的逻辑、东方的关联和类比,都是走向生态文明的必须。     

Limit theorems for a general weighted process under random censoring

Necessary and sufficient conditions for weak and strong convergence are derived for the weighted version of a general process under random censoring. To be more explicit, this means that for this process complete analogues are obtained of the Chibisov-O'Reilly theorem, the Lai-Wellner Glivenko-Cantelli theorem, and the James law of the iterated logarithm for the empirical process. The process contains as special cases the so-called basic martingale, the empirical cumulative hazard process, and the product-limit process. As a tool we derive a Kiefer-process-type approximation of our process, which may be of independent interest.     

Sensitivity Analysis for Importance Assessment

We review briefly some examples that would support an extended role for quantitative sensitivity analysis in the context of model-based analysis (Section 1). We then review what features a quantitative sensitivity analysis needs to have to play such a role (Section 2). The methods that meet these requirements are described in Section 3; an example is provided in Section 4. Some pointers to further research are set out in Section 5.

工科院校音乐教育与创造性思维能力的培养

科学发现、工程设计需要创造性思维，工科院校的大学生不仅要重视科学思维的发展，也要强调创造性思维的培养。音乐教育作为人文教育的一个重要方面，同其他艺术一样对学生科学思维的发展，尤其是创造性思维的发展具有不可忽视的作用。文章从工科院校学生音乐教育与创造性思维能力发展规律之间的关系出发。阐述音乐教育是培养学生形象思维的最佳途径之一，并且提出了在工科院校学生音乐教育中培养学生的创造性思维的一些看法。     

Families of Hadamard group divisible designs

By a family of designs we mean a set of designs whose parameters can be represented as functions of an auxiliary variable t where the design will exist for infinitely many values of t. The best known family is probably the family of finite projective planes with υ = b = t² + t + 1, r = k = t + 1, and λ = 1. In some instances, notably coding theory, the existence of families is essential to provide the degree of precision required which can well vary from one coding problem to another. A natural vehicle for developing binary codes is the class of Hadamard matrices. Bush (1977) introduced the idea of constructing semi-regular designs using Hadamard matrices whereas the present study is concerned mostly with construction of regular designs using Hadamard matrices. While codes constructed from these designs are not optimal in the usual sense, it is possible that they may still have substantial value since, with different values of λ₁ and λ₂, there are different error correcting capabilities.     

Biological Markers of Environmental and Ecological Contamination: An Overview

An approach, using biomarkers (biological responses) for assessing the biological and ecological significance of contaminants present in the environment is described. Living organisms integrate exposure to contaminants in their environment and respond in some measurable and predictable way. Responses are observed at several levels of biological organization from the biomolecular level, where pollutants can cause damage to critical cellular macromolecules and elicit defensive strategies such as detoxication and repair mechanisms, to the organismal level, where severe disturbances are manifested as impairment in growth, reproduction, developmental abnormalities, or decreased survival. Biomarkers can provide not only evidence of exposure to a broad spectrum of anthropogenic chemicals, but also a temporally integrated measure of bioavailable contaminant levels. A suite of biomarkers are evaluated over time to determine the magnitude of the problem and possible consequences. Relationships between biomarker response and adverse ecological effects are determined from estimates of animal health and population structure.     

横向扩展，纵向连锁，动静结合，创建思维新机制——广州人思维机制建构探索

本篇是系列论文第二篇，紧扣广州人思维机制建构问题展开。从广州人创建思维新机制看，思维是以横向扩展（“静”中有“动”）作基础，并以纵向推移（“静”“动”结合）作深化，最终实现纵横交错的动态系统，从而全面具体把握现实发展
