Based on a contingent perspective of accounting change, this paper reviews the historical development of differential reporting in Germany, by drawing on primary and secondary sources. The main objective of the paper is to shed light on the driving forces and main influential parameters that have shaped the existing differential reporting framework. This historical approach supplies interesting insights for the current discussion on differential reporting in Germany produced by the EU Regulation on the application of International Accounting Standards. 相似文献

论中小企业的发展困境及战略选择 总被引:1,自引:0,他引:1
目前中小企业发展缓慢,甚至出现大量破产,倒闭的现象,这种现象的发生除了与宏观环境的影响外,还与中小企业自身固有的缺陷有关,文章认为要解决中小企业的发展问题,主要要从中小企业内部的主控因素出发,根据企业自身特点和市场竞争程度,科学地选择发展战略才是解决问题的前提。 相似文献

本文对韩国国内行政区域如市郡区等小地区的失业统计共同差额比进行推定的方法有联合推定量,Woolf推定量和Mantel-Haenszel推定量等。对这个推定量的可信度是通过偏差和平均平方误差的概念来进行比较的。从对京畿地区经济活动人口调查情况看,这个地区内的24个市郡单位行政自治地区的男、女失业率差额比的偏差及平均平方误差是通过本次研究提出的推定程序来推定的。这些推定数的稳定性和效率性可以通过相对偏差和相对平均误差平方根来评价。Woolf推定量或Mantel-Haenszel推定量比联合推定量更为稳定,从其效率性来看三者很相似。 相似文献

A bilinear multivariate errors-in-variables model is considered. It corresponds to an overdetermined set of linear equations
AXB=C, A∈ℝm×n, B∈ℝp×q, in which the data A, B, C are perturbed by errors. The total least squares estimator is inconsistent in this case.
An adjusted least squares estimator is constructed, which converges to the true value X, as m →∞, q →∞. A small sample modification of the estimator is presented,
which is more stable for small m and q and is asymptotically equivalent to the adjusted least squares estimator. The theoretical
results are confirmed by a simulation study.

Serving an important condition for supporting sports teaching and research in universities and colleges, sports resources in universities and colleges should be rationally allocated and utilized in a comprehensive manner. Literature data method, survey method, on-the-spot investigation method, interviewing and statistical method are adopted to conduct in-depth research on the current sports resources in universities and colleges. In an all-round way with focusing on rational utilization, multi-tier development and resources sharing, based on domestic and foreign researches and advance experience, it takes universities and colleges in Tianjin as objects of study to bring forward the feasible, efficient, rational and suitable mode of comprehensive development, utilization and sports resources sharing, and the method of resources allocation. 相似文献

This article considers a linear regression model with some missing observations on the response variable and presents two
estimators of regression coefficients employing the approach of minimum risk estimation. Small disturbance asymptotic properties
of these estimators along with the traditional unbiased estimator are analyzed and conditions, that are easy to check in practice,
for the superiority of one estimator over the other are derived.
