关于价值哲学与价值科学的思考

“价值”概念像一只随时间推移而逐渐鼓起来的麻袋,许多内容都只是后来才被装进去的。价值问题以不同的方式成为哲学研究的主题,哲学家们从不同的视角去研究价值问题,由此形成了当代哲学“价值论转向”的三种分支方向或表现形态,它们都只是“价值哲学”而非“价值科学”。价值问题既是哲学问题同时也是科学问题,光有关于价值的形而上的哲学层面的研究是远远不够的,还必须有关于价值的形而下的科学层面的研究。作为人类理性智慧把握价值问题的不同方式,这两种研究各有其适用范围,价值哲学与价值科学的齐头并进及彼此互补,将是价值研究真正走向成熟的标志。     

数据挖掘中高维定性数据的粗糙集聚类

一、引言数据挖掘的重要任务之一就是发现大型数据中的积聚现象(clusteringphenomena),并加以定量化描述。由于其处理的数据对象的特点,从分析思路和方法设计上都要充分地考虑数据类型和数据规模,主要困难在于维数灾(curseof dimensionality)问题。若将观测数据作为高维空间中的点集,则维数越高,数据点将越趋向边界,任意两个观测间的距离也将趋于同一临界值。这就导致距离聚类方法的效力减弱。而针对定性数据聚类分析中的维数灾问题,在已有的研究成果中主要有两种思路:(1)构建新的相似度或相异度指标,减小运算量,例如可以采用信息熵[1]、相…     

ESTIMATION OF A PROPORTION USING SEVERAL INDEPENDENT SAMPLES OF BINOMIAL MIXTURES

This paper considers a sequence of independent counts, with each count arising from a mixture of binomial distributions; the mixing distribution is fixed but the number of trials varies from count to count. In this common situation, an estimate of the underlying mean binomial proportion is needed. Two estimators are in general use: the arithmetic average and a weighted average of the observed proportions. Variances of the two estimators are compared and used to decide which estimator is preferred in a given context. The relative merits depend on the distribution of the proportions and the numbers of trials used.

Differences in Factors Attracting Consumers to Taiwan's Supermarkets and Traditional Wet Markets

Exit interviews were used to summarize factors attracting consumers to six supermarkets and three wet markets in a representative city. Using the history of the marketplace as the foundation for analysis, the strengths and weaknesses of the two retail formats are introduced and are compared to the consumer response data. Findings indicate that the decline of Taiwan's traditional markets will probably continue until all are replaced by new retail formats. Currently, the traditional market is in the weakest of all the retail positions since it supplies the needs of a shrinking population of older consumers with preferences and shopping behaviors unlike those of younger, nontraditional consumers. Supermarket expansion is slowing because new hypermarkets, convenience stores, and warehouse stores are competing to satisfy the needs of the younger, more mobile target population. Overall, store formats that provide lower prices, sales promotions, a good environment, good product quality, and good service have the greatest opportunity to build consumer loyalty and increase market share.     

马克思人的本质论与“以人为本”的实现 ———对现代农民问题的解析

关于马克思的人本质理论的理解,不仅仅是停留在其在现实性上是一切社会关系总和的层面上,而是应该纵观马克思的全部理论和在其主要发展轨迹中来把握。马克思对人本质的论证事实上是在三个层次:现实性、理想性、实践性上来进行的,从而给我们解析当代农民问题提供了理论框架,即在人本质的现实层面上分析当代农民状况、在人本质的理想层次上把握农民的发展、在人本质的实践层次上解构农民的行为。     

A unified sequential test procedure for simultaneous testing the equality of several binomial proportions to a specified standard

In this article, we propose a unified sequentially rejective test procedure for testing simultaneously the equality of several independent binomial proportions to a specified standard. The proposed test procedure is general enough to include some well-known multiple testing procedures such as the Ordinary Bonferroni procedure, Hochberg procedure and Rom procedure. It involves multiple tests of significance based on the simple binomial tests (exact or approximate) which can be easily found in many elementary standard statistics textbooks. Unlike the traditional Chi-square test of the overall hypothesis, the procedure can identify the subset of the binomial proportions, which are different from the prespecified standard with the control of the familywise type I error rate. Moreover, the power computation of the procedure is provided and the procedure is illustrated by two real examples from an ecological study and a carcinogenicity study.     

“鸭病康”防治鸭传染病的研究(一)——“鸭病康”的治病机理研究

纯中草药制剂“鸭病康”对禽多杀性巴氏杆菌、鸡白痢沙门氏菌、大肠杆菌O_(?)等的体外抑菌作用优于青霉索、链霉素、庆大霉素和磺胺,仅次于卡那霉素;对金黄色葡萄球菌的抑菌作用优于上述所有抗菌药物。其注射剂能使小白鼠脾脏极显著增重(p<0.01),使小白鼠腹腔巨噬细胞的吞噬百分率和吞噬指数明显提高(P<0.05,P<0.01),因此能增强动物的免疫机能。
