马尔科夫人才规划模型与应用研究

介绍了马尔科夫人才规划模型，提供了一种可以用来进行组织的内部人力资源供给预测的方法，其基本思想是找出过去人事变动的规律，以此来推测未来的人事变动趋势．这一方法不仅可以处理员工类别单一的组织中人力供给的预测问题，也可以解决员工类别复杂的大型组织中的内部人力供给预测。     

人性假设与企业人力资源管理

人性假设是许多社会科学领域研究的出发点 ,企业也常常从自己的人性假设出发形成企业人力资源管理的理念。基于不同的人性假设 ,中国古代哲学、近现代西方经济学和管理学分别提出了对社会治理和企业治理的看法。在总结与分析的基础上 ,我们提出一种“混沌人”的假设。     

以科学发展观创新我国的环境标准

科学发展观是对可持续发展的新概括新发展,贯彻和落实科学发展观是构建社会主义和谐社会的必然途径。我们要把这种理念切实贯彻于制度建设中,具体到我国环境标准制度建设,就是要用科学发展观来指导环境标准的创新。     

制度是最好的伯乐

社会经济发展的实践证明,人力资源是国民财富的最终基础,决定国家强弱的因素是制度,制度具有间接的人才选拔功能。人才能否脱颖而出或能否健康成长,有赖于符合人性的公开竞争的制度安排和制度设计;而民主政治则是建立和实现制度创新的本质要求。     

论新新闻学

20世纪60年代，新闻报道中的客观性原则遭到前所未有的怀疑和挑战，一种全新的新闻报道思潮——新新闻学悄然出现在美国，该文论述了新新闻学的内容及社会背景，客观地评价了新新闻学的理论及实践中的价值。     

一种防空C~3I系统的效能分析方法

本文讨论了一种评定C~3I系统效能的方法。这种方法是根据系统完成使命的能力和系统的内部结构两方面的分析来完成的。通过对IFFN系统的评定,对本方法进行了举例说明。     

Storage of irradiated human blood; a source of error in quantitative chromosome analysis

Summary Human whole blood was irradiated with 2.5 Gy of 220 kVp X-rays and stored before culture with 9.7 M BrdU and 19.4 or 38.7 M BrdU for 0, 24, 48 and 72 h. The frequency of dicentrics and ring chromosomes was determined in cells staining as first division (M1) metaphases with the fluorescence plus Giemsa technique. Storage had no influence on the observed aberration yields in 44 h cultures containing 9.7 M BrdU. In 66 h cultures at 19.4 M BrdU the observed yields after 2 and 3 days' storage were significantly lower as compared to cultures from fresh blood. No storage effect was revealed in 66 h cultures containing 38.7 M BrdU. In cases where cytogenetic radiation dosimetry has to be carried out using blood samples which have been in transit for 2–3 days, the findings are of relevance for a correct determination of the chromosome damage in M1 cells.     

“新文科”建设背景下经济学人才培养的路径研究

“新文科”建设是新时代对人文社会科学教育提出的新要求。如何在“新文科”理念下培养经济学人才,是中国经济学建设的一个重要课题。首先,从时代性、战略性、创新性、交融性和发展性5个特征维度阐释“新文科”建设的内涵;其次,探讨“新文科”建设背景下经济学人才培养存在的主要问题;最后,提出经济学人才培养需要持续优化经济学专业培养目标和培养方案;加强经济学的课程思政教育,推动济学与其他学科的交叉融合,推动经济学人才培养模式创新以及培养学生解决问题的能力等路径。研究结果可为培养适应新时代发展的经济学人才提供理论参考。     

Self-labeling of human polymorphonuclear leucocyte myeloperoxidase with125iodine

In order to obtain a radioimmunoassay (RIA) technique for the measurement of human plasma myeloperoxidase (MPO), we purified the enzyme from polymorphonuclear granulocytes (neutrophils), and compared three methods of labeling it with¹²⁵Iodine: chloramine T, lactoperoxidase, and an original technique of self labeling based on the ability of the enzyme to oxidize and bind¹²⁵I in the presence of H₂O₂. The chloramine T technique produced a degraded protein, as well shown by a high non-specific binding of tracer to antibody. The lactoperoxidase technique did not succeed in labeling MPO with an adequate specific activity. In contrast, the self-labeling method gave a stable tracer with a specific activity of 23 Ci/gmg MPO (85 MBq), a satisfactory level of immunoreactivity, and a low-specific binding (3%). After labeling, purification of tracer was achieved by gel filtration chromatography in phosphate buffer (0.05 M; pH7) to which 0.1% poly-L-lysine was added. The labeled molecule remained stable for 40 days and could be used for RIA with a polyclonal antibody raised in rabbits.
