开拓性的成功经验——陈云领导接管沈阳述论

沈阳是中国共产党在解放战争时期接收的第一座大城市,其开拓性地接管沈阳的成功经验,是在陈云同志直接领导下创造的。在接管沈阳的过程中,以陈云为主任的军事管制委员会解决了如何接收得迅速稳妥,接收后如何尽快恢复社会秩序等一系列问题,充分体现了高超的社会组织才干和管理城市的能力,为中共中央全面总结接管城市的经验,顺利实现工作重心的转移发挥了巨大的指导作用,在中国现代史上留下了闪光的一页。     

基于政府与企业合作的应急物资存储成本控制问题的研究

本文针对政府储备应急物资过期报废损失严重、存储成本高的问题,提出了政府委托企业储备应急物资的方案,并对委托合作后政府如何激励企业降低应急物资存储成本的问题进行了研究。首先对政府与企业合作前后应急物资储备成本进行了分析,寻找能使节约成本公平分配的条件,继而在企业尽最大努力降低应急物资存储成本的条件下,建立了政府成本节约期望效用最大化的激励模型。最后用算例验证了政府和企业合作后存储成本控制的问题。     

从《诗经》里醒来的美学刺猬——张蜀恒“诗歌评书”的声音诗学考察

在内蒙古汉语诗歌写作群体中,诗人张蜀恒绝对是个异类。张蜀恒对＂诗歌＋评书＂的立体诗歌范式进行了先锋实验,主张＂诗歌评书＂的表演技巧主要有嗓子活、面子活、身子活等。本文就张蜀恒＂诗歌评书＂所表现出的声音诗学,从三个方面进行阐述：一是诗人不自觉的回到诗歌最初的形式尝试,以及与《诗经》的诗学关联;二是以方言入诗的＂以暴制暴＂问题;三是诗人介入生活的努力,即加大诗歌表现的民生容量。从中我们都能感受到了张氏声音诗学的独特魅力。

文章分析了人口承载力模型和适度人口量化测算模型,对陕西省人口承载力与适度人口规模进行定量估计,探讨了陕西省人口与经济社会、资源环境协调发展的对策。     

范氏气体准静态过程的基本关系式

本文导出了v摩尔范氏气体几种常见准静态过程的基本关系式,并给予了一定的物理解释。同时又指出当a=0、b=0时,上述范氏气体关系式正好完全转变为理想气体各相应关系式。     

A multi-treatment two stage adaptive allocation for survival outcomes

A multi-treatment two stage adaptive allocation design is developed for survival responses. Assuming noninformative random censoring, asymptotic p values of relevant tests of equality of treatment effects are used to derive the assignment probability of incoming second stage subjects. Several ethical and inferential criteria of the design are studied, and are compared with those of an existing competitor. Applicability and performance of the proposed design are also illustrated using a data arising from a real clinical trial.     

价格波动与资源配置效率研究

 文章从理论和经验两方面研究了价格波动对资源配置效率的影响。理论模型显示：由于调整成本的存在,面对较低水平价格波动的企业可能并不会立刻调整要素投入比例和生产计划,这一“保守策略”意味着价格波动可能带来企业配置效率损失的增加。但是随着价格波动幅度进一步增加,越来越多的企业将会主动的对生产计划进行调整,以便抵消较大幅度波动的不利影响。“保守策略”向“调整策略”的转变意味着价格波动引起的资源的配置效率损失可能存在门阀效应。利用1978-2007年省级面板数据和基于极大似然估计的随机前沿方法,文章实证研究证实了价格波动对资源配置效率损失的非线性影响,认为传统的研究可能低估价格波动对经济的负面影响。     

Using queueing models to estimate system capacity

The true capacity of a production or service system is often difficult to estimate with sufficient accuracy. The two main methodological approaches to capacity measurement described in the literature – measurements based on engineering and physical factors and measurement based on time studies – are both characterised by conceptual as well as practical shortcomings. This paper provides analyses on how capacity measurement can be approached using queueing models, thereby eliminating some major drawbacks of other approaches. The core idea is to use the theoretical relation among arrival rate, service rate and queueing time; because the arrival rate and queueing time can both be measured objectively in an empirical sense, these measures can be used to estimate the true service rate of the system. The suggested method is completely insensitive to the proportional relationship between design and effective capacity, and it cannot cause any behavioural problems during measurement since it does not require direct observation of the system itself. Particularly appealing is the potential for practical application to many contexts in many industries. The validity of the approach is discussed.     

Production quantity allocation for order fulfilment in the supply chain: a neural network based approach

In the current global business environment, it is very important to know how to allocate products from the producer to buyers (or distributors). If products are not appropriately distributed due to absence of an effective allocation policy, the producer and buyers cannot expect to increase customer satisfaction and financial profit. Sometimes some buyers can order more than the actual demand due to inappropriately forecasting customer orders. This is the big obstacle to the effective allocation of products. If the producer can become aware of buyers’ actual demands, it is possible to realise high-level order fulfilment through the effective allocation of products. In this study, new allocation policies are proposed considering buyers’ demands. The back propagation algorithm, one of the learning algorithms in neural network theory, is used to recognise actual demands from the previous buyers’ orders. After excluding surplus demands included in buyers’ demands, products are allocated to buyers according to one of the existing allocation policies depending on the company's decision. In the numerical examples, new allocation policies reducing buyers’ surplus demands outperform previous allocation policies with respect to average amount of backorder.     

Stimulating lifelong professional growth by guiding job characteristics

This article reports some findings from a broader study concerning the development of professional expertise. The aim of the part that is described in this article was to find out whether certain job-related factors situated in the domain of socio-technical systems design (STSD), that is, control capacity, job satisfaction, and learning value of the job, influence the development of professional knowledge, skills, and capabilities throughout the career. The sample consisted of 559 middle- and higher-level employees working in eight large Dutch companies. Theoretical contributions from learning theory, human resource management and work, and organizational psychology are used to conceptualize the phenomenon of professional expertise and to develop a theory of expertise development in careers. By providing insight into the relationships between several job-related factors, on the one hand, and the development of professional expertise, on the other, this research is intended to contribute to theory building in adult development and learning. Influential job characteristics that are situated in the domain of STSD seem to be of high importance in view of a further human resource development. Paying close attention to an individual's job and its content is indispensable in order to guide growth throughout the career and to enable life-long development of professional expertise.
