基于生命周期的领导风格对人力资源管理实践影响研究

通过对87家中国制造企业的实证研究发现,在企业生命周期的创业阶段,变革型领导对内部职业机会、培训和员工参与有显著影响,交易型领导对人力资源管理实践有显著影响;在快速发展阶段,交易型领导对人力资源管理实践有显著影响;在成熟阶段,变革型领导和交易型领导都对人力资源管理实践有显著影响;在衰退阶段,变革型领导对人力资源管理实践有显著影响,交易型领导对内部职业机会、培训和员工参与有显著影响。     

菊科莴苣属订正及亚洲大陆菊科植物二新属

本文是对菊科莴苣属Lactuca L. 的分类订正, 文中起用了乳苣属Mulgedium Cass.和山   莴苣属Lagedium Sojak两个较老的属名, 建立了二个新属，即翅果菊属Ptrocypsela Shih与假   福王草属Paraprenathes Chang. 文末提供了莴苣属及邻近属以及东亚地区的有关种类的分属分种检索表。     

我国生物安全问题的现状分析及对策

在跨越了改变自身以适应环境和改变环境以适应自身的两大历史阶段之后,人类社会已进入到既能改变环境又能改变自身的历史新时期。由生物技术带来的安全风险具有人类历史发展的必然性,只能面对而不能回避。除空天、海洋、网络、传统安全外,生物威胁已上升为新的安全疆域,在当前我国重要战略机遇期构成了全新的安全需求。文章简述了自SARS暴发以来国内外生物安全问题的发展态势,深入分析了当前我国所面临生物安全威胁的现实特点。在对前人所做生物安全问题研究的基础上,总结归纳出了生物安全理论的框架。同时,以生物安全理论内涵为指导,对未来我国所面临生物安全威胁的发展走向进行了预测,提出了以新观念主导战略能力建设、以理论创新主导科技支撑、以体系应对新型生物性危害的实施策略。     

员工公平感影响因素的实证研究

本文通过对苏州高新区内71家企业427位员工的调查访问,研究了工作种类、行业类别和企业性质对员工公平感的影响。工作种类变量对员工的内部公平感和外部公平感都无显著影响;企业所在行业变量对员工的内部公平感和外部公平感都有显著影响;在企业性质变量上,其他企业中员工内部公平感要显著高于台资企业和日资企业,在日资企业中,机械行业员工对外部公平感受要显著高于IT行业。     

菊科亚菊属川甘亚菊类群订正

本文对作者本人在1983年《中国植物志》第76卷第一分册12l页上针对川甘亚菊处理过宽的问题，重新作出了订正。本文确认川甘亚菊、灰叶亚菊、深裂亚菊及下白亚菊分别为不同的种，并作出了这四个种的分种检索表。     

热水溶液中CH_4和CO_2之间碳同位素交换的初步研究

230℃和250℃温度下溶液中CH_4和CO_2之间的碳同位素交换反应的实验初步证实它们在水溶液中要比在于系统中容易进行同位素的交换。不同条件实验的比较表明溶液的酸度(或pH)、CH_4/CO_2(摩尔)和反应容器的大小等都会明显地影响同位素交换的速度。文中描述了实验方法,并从机制上初步讨论了实验结果。

三种数值方法在几种六道木分类中的应用

   In the last 10—20 years there has bee n increasing awareness of the problem con- cerning the aims and practices of taxonomy.  In particular, there has been growing interest in the development of numerical methods in biological taxonomy as an aid to making systematics a quantitative science, a step which comes in time to almost every scientific discipline.       Numerical taxonomy is the evaluation by numerical methods of the affinity or  similarity between taxonomic units and the employment of these affinities in erecting a hierarchic order of taxa.  The present rapid development of these ideas is presuma- bly a result of the development of computer techniques.       Numerical taxonomic approach has been applied to the studies of entomology and microbiology in China to some extent since 1975. But so far it hasn’t been commonly used in botany.  The present report is a preliminary study on 9 spp. of the genus Abelia.  A set of binary data with 54 characters  is  used  for  computing association coefficient; and a set of quantitative data with 47 characters for distance coefficient and correlation coefficient. For the mathematical models were chosen the non-metric  simple matching association coefficient, the geometrical distance of Riemannian space and correlation coefficient.  Computational procedures are stepwise presented in detail and computer programmes are written in the background of Algol-60 language. Cluster analysis is compared with simple linkage,  average  linkage  and multi-correlation.      The results of DC and CC for 9 spp. of Abelia agree closely with the traditional taxonomy, because the data we collected mainly come from morphological characters. It would seem that the results of quantita tive data are more appropriate for  seed plants.  It is, therefore, postulated that our programes are complementary and very useful to a wide range of classification entities, such as microbes, animals and plants in present situation in China.      In conclusion, a comparison between the  conventional taxonomy  and  numerical taxonomy has been made, and a brief discussion of three problems, i.e. the monothetic versus polythetic, divisive versus agglomerative, weighting versus unweighting.
