常规兵器试验设计和开发过程中的质量控制

通过对常规兵器试验如何进行＂设计和开发过程的质量控制＂这一具体问题的研究,将PDCA循环管理模式用于试验的设计和开发过程。文章结合常规兵器试验设计和开发的工作实际,探讨了在试验设计和开发工作中借鉴PDCA循环理论与实践,进一步提升试验设计和开发的工作效益,使试验设计和开发向标准化发展,进而促进试验设计和开发质量的全面提升。     

企业组织中特定人力资本的道德研究

道德逐渐成为现代企业组织竞争的基本条件和核心,是企业长期利润的来源之一。本文通过研究道德的载体—人力资本与道德的关系,提出动机—行为模式;通过研究对道德起更重要作用的特定人力资本道德,提出如何提高整个企业组织的道德水平并最终形成善的道德循环。     

High-growth recoveries, inventories and the Great Moderation

We present evidence about the disappearance of the high-growth recoveries from recessions with intense job creation typically observed until the eighties. This result matches the belief that recessions now have an L-shape as opposed to the old-time recessions that always had a V-shape. We also show how this change in business cycle dynamics can explain part of the Great Moderation. We postulate that these two phenomena may be due to changes in inventory management brought about by improvements in information and communications technologies.     

经济转型期多元化经营的风险及对策

多元化还是专业化,这是企业发展过程中常遇到的问题,也是企业最困惑的问题之一。一般地,当宏观经济处于增长期,则行业发展趋好,行业竞争较弱,此时多元化经营比较容易成功;当宏观经济处于成熟期和衰退期,则行业发展趋势变坏,行业竞争加剧,多元化经营则难以成功。经济转型将使传统行业的发展趋势受到不利影响,从而加大多元化经营的风险。     

等概率条件下的转弯型堆垛机作业效率的计算研究

转弯型堆垛机是自动化立体仓库中实现货物自动存取的关键设备,文中对转弯型堆垛机效率问题进行研究。在假定等概率拣取货物的条件下,分别推求转弯型堆垛机的平均单一作业和复合作业循环周期和作业效率的计算公式,并利用华南理工大学仓储综合实验室的基本数据进行了作业效率的实证计算,从而为自动化立体仓库系统的建设设计和有效管理提供依据。     

Assessing the reversal of investor sentiment

Assessing the reversal of sentiment in stock markets is needed because, according to the social mood cycle, the change of social mood over time is an antecedent of price movements. The purpose of this study is to empirically assess reversal of investor sentiment, to show the phases of social mood cycle from increasing mood to decreasing mood, and to explain the dynamic change in market inefficiency from increasing to decreasing. Growth modeling, developed particularly for dealing with the change over time, is used in this study for assessing the reversal of investor sentiment. The autocovariance structure of errors and the variances/covariances of the random coefficients are all taken into account in the model. The results have indicated that the change in investor sentiment over time is inverted U-shaped for the entire market. Moreover, arbitrage constraint and stock characteristics exert a joint moderating effect on sentiment reversal. Less arbitrage constraint can strengthen sentiment reversal only when the market for individual stocks is dominated by noise traders. Based on the results obtained, we discuss asset pricing, liquidity management, and market intervention.     

基于生命周期的虚拟企业知识活动分析及其伙伴选择过程研究

随着新经济的到来,知识越来越成为企业快速响应市场机遇和获取竞争优势的最短缺资源。而企业自身知识资源的有限性使企业越来越多地采用虚拟企业的高级形态——知识联盟型虚拟企业来弥补企业知识资源的不足以快速响应变化的市场需求。首先对知识联盟型虚拟企业的知识缺口类型进行研究和划分,然后分析并描述虚拟企业生命周期各阶段的知识活动;在此基础之上,探讨虚拟企业组建阶段考虑知识要素的伙伴选择过程;最后,针对不同的知识缺口,提出伙伴选择过程的评价指标体系设计中应考虑的知识性因素。     

Dating the ‘world business cycle’

By mid-2008 the world was witnessing the unfolding of a relatively rare macroeconomic phenomenon, namely, the onset of what one might call a synchronized international – or ‘world’ – recession. But what exactly is a ‘synchronized world recession’? This article proposes a practical definition of a ‘synchronized world recession’ and a putative set of historical post-WWII dates for a ‘world business cycle chronology’. Further, using a constructed ‘world coincident index of economic indicators’ and an associated ‘world leading index of economic indicators’, this article demonstrates that evidence was available from early in the second half of 2007 that the world was indeed sliding inexorably towards its fourth synchronized world recession since WWII (although, interestingly, already its second of the twenty-first century!).     

The cyclicality of consumption,wages and employment of the public sector in the euro area

This study empirically examines the business cycle behaviour of public consumption and its main components, the public wage bill (including its breakdown into compensation per employee and public employment) and intermediate consumption, in the euro area aggregate, euro area countries and a group of selected non-euro area Organization for Economic Co-operation and Development (OECD) countries (Denmark, Sweden, the UK, Japan and the US). It looks across a large number of variables and methods, using annual data from 1960 to 2005. It finds robust evidence supporting that public consumption, wages and employment co-move with the business cycle in a pro-cyclical manner with 1–2 year lags, notably for the euro area aggregate and euro area countries. The findings reflect mainly the correlation between cyclical developments, but also point to an important role of pro-cyclical discretionary fiscal policies.
