人性·人本·人化--人本管理的实质及其管理实现

管理理论的建构常常以某种人性假设为前提.对复杂人性本质的不同推定,决定着管理科学理论的不同走向.人本管理是一种有别于其他诸如"物本管理"、"资本管理"、"能本管理"等的管理理论,其不同之处或者说其进步性就在于它谋求对人的理解,即试图在对人性的种种假设中探寻"人"与人之"本"的内在逻辑,以建立一种"人为"与"为人"的柔性的管理规约.在我国特有的管理语境中,人本管理的本质与实现的理解是有其独特性的.在管理实践中,人不仅仅是手段,人本身也是目的.     

浅谈能本管理在企业管理中的重要性

简要介绍了能本管理的涵义及其基本理念，重点阐述了能本管理的制度安排主要体现在用工制度、用人制度、分配制度和领导制度4个方面，同时指出能本管理的组织操作实质上就是建立一种“各尽其能”的运行机制，根据我国企业的组织结构，最重要的是建立一种“能级制”。     

关于实践在人类社会形成和发展作用的再思考

实践使自然世界分化出人化世界，实践是人类社会形成的基础。而且实践又是构成人类社会发展的动力，实践的这个作用一直被低估。本文着重就实践在人类社会形成和构成人类社会发展的动力方面，进行再思考和分析。

Immunogenetics

Summary The 1985 Catalog of Mapped Genes (Human Gene Mapping 8; 33) has been used to pick out the known, immunologically important genes; these are then discussed in the following order: 1. genes controlling organs, tissues and cells of the immune apparatus, 2. genes determining self structures, 3. genes determining the structures of immunological specificity, 4. genes determining substances with immunoregulatory and effector properties. The symbols for the genes and the biological functions of their products are explained. The genetics of the ABO blood groups, of the HLA-system and of antibody formation are given in rather more detail.     

In vitro amiodarone protein binding and its interaction with warfarin

Summary The binding of amiodarone to human plasma protein and to bovine serum, albumin was studied by three different methods, ultracentrifugation, equilibrium dialysis and fluorescence spectroscopy. The fraction of amiodarone bound to plasma protein amounted to 96.3%. The changes in the binding properties of 1-anilino-naphthalene-8-sulfonate for bovine serum albumin using warfarin and amiodarone as independent inhibitors were analyzed in terms of binding site specificity. The findings indicated that amiodarone and warfarin have two different binding sites on bovine serum albumin, so a noncompetitive inhibition mechanism was indicated. On the basis of our data we cannot exclude other mechanisms of interaction besides direct displacement of one drug by another; nevertheless, metabolite interference between amiodarone and coagulation cofactors may better explain the enhancement of warfarin's pharmacological action in association with amiodarone.This work was partially funded by the CNR (National Research Council, Rome, Italy), Program on Clinical Pharmacology and Rare Diseases. The authors would like to thanks Drs E. Marzi and E. riva for their help.     

Bicuculline and picrotoxin block γ-aminobutryic acid-gated Cl− conductance by different mechanisms

Summary Using isolated, internally perfused bullfrog dorsal root ganglion cells we have studied the dose-response curves for -aminobutyric acid (GABA) in the presence of internally or externally applied GABA antagonists. With external application of antagonists the inhibition of the GABA current by bicuculline was competitive and that by picrotoxin was noncompetitive. Picrotoxin but not bicuculline blocked when internally perfused.To whom reprint requests should be addressed.Acknowledgments. We thank Drs S. Minakami and S. Yasui for helpful discussions and comments.     

基于逻辑相似性的运动检索算法

针对基于内容的人体运动检索问题,提出了一种基于逻辑相似性的运动数据检索方法。首先,针对特定人体运动序列数据,使用自组织网络映射算法对运动数据进行预处理,找出运动数据帧的最佳匹配单元。然后,应用数据编码规则对匹配单元进行量化及编码处理,获得基于符号化表示的运动描述符。基于符号化表示的描述符建立运动序列索引机制,应用多分辨率框架进行运动模式匹配。最后,按照模式匹配结果进行运动相似性排序,输出检索结果。在CMU运动数据库中的试验结果表明了算法有效性。
