Innovators and contrapreneurs: Crucial alliances that connect and separate organizational change processes

This paper focuses on the coupling among alliances, relationships, management, and activities, when major strategic changes are carried out in an old organization. The paper also points out hownew alliances andchanged relationships seem to be developing in a Norwegian company. As a conclusion, we point out six elements which, according to our research, have to be present to minimize the implementation of reversible processes in organizations where organizational change processes have been implemented so that continued change can go on in the company.

Schiff碱型双(苯并-15-冠-5)对碱金属苦味酸盐的萃取性能研究

用五种Ｓｃｈｉｆ碱型双（苯并＿１５＿冠＿５）为离子载体,在水＿１,２＿二氯乙烷体系中研究了其对碱金属苦味酸盐的萃取性能,测定了分配比Ｄ和萃取平衡常数Ｋｅ．结果表明,这些双冠醚与苦味酸钠以１∶１（冠醚单元∶金属离子）形式络合,而与苦味酸钾和苦味酸铷则以２∶１形式络合．     

A continuous 200-ka palaeoclimatic record from stalagmite in Tangshan Cave, Nanjing

An oxygen isotope temperature record from 381 to 166 kaB. P. (²³⁰Th/²³⁴U dating and tuned ages) has been obtained by combining data on the isotopic composition of calcites with that of fluid inclusions trapped in a stalagmite from a limestone cave in which a fossil cranium deposited. Several laminae in microsequence of the stalagmite represent climatic events or shifts. The Nanjing man fossil was older than 381 kaB. P.     

On some tests-based projection pursuit for elliptical symmetry of a high-dimensional distribution

Some test statistics of Kolmogorov type and Cramér-von Mises type based on projection pursuit technique are proposed for the testing problem of sphericity of a high-dimensional distribution. The limiting distributions of the test statistics are derived under the null hypothesis and under any fixed alternative. The asymptotic properties of bootstrap approximation are investigated. Furthermore, for computational reasons, an approximation for the statistics, based on the number theoretic method, is suggested. An erratum to this article is available at .
