竖向地震力的冲量计算法

一般认为地震在地表引起的破坏主要是S波的水平震动,很少考虑地震竖向力的作用。单从考虑地震水平力的作用是不易全面反映震害特征的。提出用冲量法来研究计算竖向地震力,通过对最大竖向地震力分布研究,探讨竖向地震力对建筑物的影响与破坏,为进一步提高工程抗震设计水平提供理论依据。

家族企业的传承冲突与解析

改革初期的我国第一代家族企业,在21世纪初都将逐步进入家族企业的权杖交接的重要阶段.如何从"第一代"创业者手中将企业传递到"第二代"家族企业的管理者手中,将越来越成为企业的重要课题.家族企业子承父业中的种种冲突的根源在于继承者的能力、权威不足或管理风格与原企业风格不协调.家族企业需要根据继承者的不同发展阶段系统地培养继承者.     

Interest,sensemaking and adaptive processes in emerging business networks — An Australian biofuel case

We contribute to the literature, firstly by elaborating sensemaking as an inter-organizational process. Second, we contribute by displaying how processual research captures reality in flight. Third, an interest model is developed in conjunction with how managers jointly develop an understanding and adapt their surrounding business network, so as to fit R&D into the social-economic environment. We develop the concept of inter-organizational sensemaking by elaborating the in-between; a joint and multi-actor understanding of the way resources-activities and the network of actors can change. Sensemaking is undertaken purposefully and so the interests of society, individual managers, firms and the mutual interests inherent with inter-organizational change also play a part. Our processual method studies events and activities through sequences of phases and periods defined by the researchers. A longitudinal case study of an emergent biofuel network exemplifies this approach. The paper discusses future research and managerial implications.

中俄石油合作的历史与阶段研究

中俄两国在石油领域的合作走过了十八年的历程。纵观这一历程,总体而言,两国石油合作十多年来一直在磨合,磨合发展过程当中有发展有延伸。目前两国石油合作进展顺利,2010年底中俄支线石油管道将修成,明年将进入正常运转,未来合作前景非常广阔。具体而言,中俄两国石油合作的历程可分为四个不同的时期或阶段,每一个时期与阶段有着不同的时机与特征。     

浅论建设工程项目待摊支出分配问题

在投资某项建设工程过程中,需要对相关支出进行待摊处理。现行的待摊支出分配方法因没有考虑资产的服务年限及成本动因,可能造成固定资产计量的不合理。对大型项目而言,应以项目投资为基数、以资产服务年限为权数分配待摊支出。     

The role payment depreciation in short temporal separations: Should online retailer make customers wait?

In recent times, it has become common for customers to pre-pay for goods but consume them later. The pain of payment reduces over time, in a phenomenon called payment depreciation (PD). Researchers have examined this phenomenon in situations when payment precedes consumption by long periods, ranging from three weeks to several years. The present study examines the occurrence of payment depreciation when costs precede benefits by short periods, such as three days to two weeks. The three experiments establish the presence of PD in short intervals of less than two weeks. The results are robust for both inventoried and non-inventoried consumption. The results further suggest that the sunk cost of a payment devalues discretely and not continuously. The value of the sunk cost in the consumer's mental account drops significantly after two weeks, as compared to one week. The results fail to demonstrate the effect of payment mode on the payment depreciation phenomenon. Implications indicate that retailers can vary their order delivery period to reduce product returns.     

Mandatory and Voluntary Disclosures: Dynamic Interactions

Firms sometimes obtain soft private information about growth prospects along with hard information about current or past performance. In this environment, we find that optimizing disclosures over multiple periods yields nonlinear stock price reactions following both voluntary and mandatory disclosures. Further, we derive several predictions about distinct short‐run and long‐run effects of disclosures and nondisclosures on security prices. Under specified conditions, when the volatility of the firm's earnings increases, the average contemporaneous and prospective post‐mandatory‐disclosure market premia (for voluntary disclosures over nondisclosures) rise, while farther‐in‐future market discounts (for such voluntary disclosures) also become larger. Our analysis moreover predicts that both the disclosure probability and the information content of nondisclosures can increase in the persistence of earnings.
