企业资产结构的影响因素及模式研究

资产结构是指企业资本在不同资产形态上分布状况及分配比例。资产结构一般具有整体性、封闭性、动态性等特征;资产结构的形成受到诸多内外部因素的影响。本文研究了影响企业资产结构的因素,分析了资产结构的类型,并根据资产变现性的特征,将资产结构模式分为三种类型。     

实行分层教学 提高学生英语综合能力

高职学生英语能力弱 ,知识水平参差不齐 ,两极分化现象严重。高职新生的英语水平起点不同 ,学习行为和学习方法不同 ,学生之间的学习能力具有差异。采用相同的教学目标 ,不同的教学手段和要求 ,多管齐下的方法 ,让不同层次学生的英语水平都有所提高。     

浅析产业内贸易理论

随着各国经济发展和人均收入水平的不断提高,产业内贸易的比重越来越大。以“国际产品异质性”、“需求偏好相似”、“规模经济优势”三个原理为支柱的产业内贸易理论对此进行了有效的解释,并以一个全新的视角对国际经贸理论进行了发展和完善。掌握这一理论无疑对我国产业结构的调整和贸易政策的制定都有着积极的借鉴意义。     

农业自然资源与食物生产的类型迭置分析—以福建省为例

福建省粮食缺口逐年拉大,其它副食品也出现程度不同的短缺信号。在食物短缺的背后隐含着农业自然资源数量的短缺,并且随着人口的增长而日益严重。本文从农业自然资源与食物生产的内在联系入手,尝试对其丰乏程度进行定量的地域划分和迭置分析,进而探索各地域类型的食物发展方向与总体对策。     

农地利用技术创新的类型与模式研究

农地利用技术是一个多层次的体系，它能在扩大耕地面积、提高土地利用率和耕地质量等多方面发挥重要作用。通过对“市场机制自发作用下的技术选择”和“政府引导下的技术选择”两种现实模式的探讨，认为技术创新具有外部性，土地利用更是具有明显的“外溢效应”，加上我国农业比较利益偏低和农地使用权流转市场发育不全带来的农地价格扭曲，常造成市场机制下技术创新的方向与资源稀缺状况不相符合的现象，从而带来资源配置的低效率。因此，适当的政府引导是必要的，也是有效的。     

中低层灵活就业群体的异同分析与对策

中低层灵活就业群体主要由下岗工人与农民工组成,他们是就业群体中的弱势群体,如何对他们进行更好的制度安排,促进灵活就业的发展,对于缓解就业压力有着积极的意义.中低层灵活就业中的两大类群体在就业方面既存在共性又存在区别,对此进行分析能更好地促进他们实现灵活就业,并为政府采取有针对性的措施提供参考.     

The formation and early development of German audit firms

This paper examines the emergence of audit firms in Germany through an analysis of contemporary sources. Special attention is paid to the range of services offered, their legal forms and ownership structure. In Germany, the demand for external audits developed because the corporate supervisory boards had been unable to fulfil their monitoring task satisfactorily. As a consequence of the major economic crisis of 1929-1931 and the collapse of large corporations caused by the fraudulent actions of managing directors, statutory audits for stock corporations were introduced in 1931. The first German audit and trust company, the Deutsche Treuhand-Gesellschaft, was established much earlier in 1890. Like other trust companies which emerged from 1905 onwards, it was owned by large banks. After the First World War, large commercial groups on the one hand, and the state on the other hand, started to form their own audit firms. Most of the audit and trust companies used the legal form of a corporation. Originally, the main activities of the trust companies were trustee activities and audits. Subsequently, they also offered tax and business advisory services. These features (a broad range of services offered, the corporation as the dominant legal form, and clients who are also owners) help us to understand key characteristics of modern German audit firms such as their limited liability to third parties.     

Revisiting the Miles and Snow strategic framework: uncovering interrelationships between strategic types,capabilities, environmental uncertainty,and firm performance

The Miles and Snow strategic type framework is re‐examined with respect to interrelationships with several theoretically relevant batteries of variables, including SBU strategic capabilities, environmental uncertainty, and performance. A newly developed constrained, multi‐objective, classification methodology is modified to empirically derive an alternative quantitative typology using survey data obtained from 709 firms in three countries (China, Japan, United States). We compare the Miles and Snow typology to the classification empirically derived utilizing this combinatorial optimization clustering procedure. With respect to both variable battery associations and objective statistical criteria, we show that the empirically derived solution clearly dominates the traditional P‐A‐D‐R typology of Miles and Snow. Implications and directions for future research are provided. Copyright © 2004 John Wiley & Sons, Ltd.     

Truthful germs are contagious: A local-to-global characterization of truthfulness

We study the question of which social choice functions from an abstract type space to a set of outcomes are truthful, i.e., implementable by truthful mechanisms, when utilities are quasi-linear. For convex domains, our main theorem characterizes truthful social choice functions as those satisfying two properties: local weak monotonicity and vortex-freeness. The first of these constrains the function values at any two sufficiently proximal points, while the second asserts that its line integrals around sufficiently small triangular loops must vanish.The characterization implies a local-to-global principle that allows one to deduce truthfulness of a function from its behavior on arbitrarily small neighborhoods of each point. Other consequences include a simple alternate derivation of the Saks–Yu Theorem that weak monotonicity characterizes truthfulness of functions having a convex domain and finite range, and a sufficient condition for constructing truthful functions by “stitching together” truthful subfunctions on different subsets of the domain.     

刚度不均匀分布的连体结构的抗震性能分析

通过连接体将两个或两个以上的独立塔楼连接在一起,形成连体结构。在地震作用下,塔楼的变形和内力变化复杂,且两塔楼之间的耦联效果显著。本文采用弹塑性时程分析法,研究其在罕遇地震作用下的动力响应,并且通过对不同对称性、平面内不同刚度分布、不同跨度的结构进行弹塑性时程分析,分析结构的对称性、跨度的参数对结构动力响应的影响。
