企业的组织能力理论刍论

本文认为人在理性的动机之下，会表现出信任或机会主义的行为倾向。企业的发展壮大需要代理人之间的信任与合作，而引发信任抑制机会主义需要企业具有“组织能力”，即“签订”组织内部的默契等隐含契约的能力。组织能力的提高是企业进行规模扩张的必要条件。具有强大的组织能力的企业将主动进行边界扩张以寻求规模和企业价值的最大化，而不是如传统的交易成本经济学所预期的那样只是被动地为节约交易成本而进行边界决策。     

唐诗语篇中的隐性衔接探微

基于韩礼德和哈桑提出的语篇衔接理论,结合其他学者在语篇衔接与连贯上的研究成果,对隐性衔接这一语篇衔接手段作出界定,将隐性衔接划分为隐喻衔接与意象衔接两大类,并将其应用于唐诗语篇的分析之中。通过对唐诗语篇中隐性衔接的初步探讨,使读者更好地理解与欣赏唐诗这一特定语篇,并对诗歌的教学有一定的指导作用。     

Generalized transport costs and index numbers: A geographical analysis of economic and infrastructure fundamentals

We rely on the economic theory approach to index numbers to improve the existing definitions and decompositions of variations in generalized transport costs (GTCs). As a value index, we decompose GTCs into price and quantity indices associated to economic—market—costs and infrastructure variables—distance and time within a network. The methodology allows the accurate identification of the sources of GTCs decline. We illustrate it for the case of road freight transportation in Spain between 1980 and 2007 and at a highly detailed geographical level. Average GTCs weighted by trade flows have decreased by 16.3%, with infrastructure driving that reduction. We find large territorial disparities in GTCs, but also significant geographical clusters where the market and network indices show spatial association.     

论言外行为在大学英语教学中的运用

在英语教学中,学生往往只理解句子的表面意思,却不理解句子的言外之意,不能通过言内和言外的连贯作用把文章的深层含义理解透彻;而老师由于时间关系,可能无法详细讲解言外行为在英语中的作用,从而师生都忽视它的作用.本文从理论和实践相结合的角度分析言外行为在英语教学中的作用.

基于支持向量机的桁架桥可靠度评估

针对桁架桥结构极限状态方程一般难以显式表达的特点,提出基于支持向量机的桁架桥可靠度评估方法。通过抽样,采用桁架桥有限元计算,利用支持向量机的非线性映射和泛化能力,建立随机变量与结构响应之间的函数关系,模拟结构极限状态方程,采用优化算法计算桁架桥可靠指标。研究表明:该方法对于评估桁架桥可靠度具有较高的计算精度,但随车辆荷载随机变量的离散性增加,桁架桥的失效概率显著增大。     

水下拖缆抛物构型分析研究(英文)

This article discusses the dynamic state analysis of underwater towed-cable when tow-ship changes its speed in a direction making parabolic profile path. A three-dimensional model of underwater towed system is studied. The established governing equations for the system have been solved using the central implicit finite-difference method. The obtained difference non-linear coupled equations are solved by Newton's method and satisfactory results were achieved. The solution of this problem has practical importance in the estimation of dynamic loading and motion, and hence it is directly applicable to the enhancement of safety and the effectiveness of the offshore activities.
