大院民居的空间内容包罗万象,主要表现在居住和民居的样式上.人们对自己能感觉到的空间,常常赋予某些意义和象征,因此形成了熔建筑的实用、认知、审美,有时兼有崇拜观念于一炉的空间意识,使得大院民居的居住空间在布局安排上表现出了变幻多姿的特点,同时折射出了晋商独特的审美意识和深厚的文化底蕴. 相似文献

This paper reports findings from research conducted in six Romanian residential care homes. The aim of the paper is to examine the views held by young people, currently living in residential care, about the importance of their biological families and the option and challenge of reintegration. The data reflect the ideas and perspectives of 44 young people captured through a narrative interview approach using social mapping activities. The results indicate that most children and young people know at least one birth parent and maintain contact on their own initiative; most do not place a high level of importance on such relationships which are generally characterised by lack of confidence, low security and a presumed limited capacity on the part of the biological family to meet their needs. Family reintegration is considered to be a viable option for a small number of young people; others do not see it as realistic because of the impact of long-term separation and the likelihood of experiencing poorer living conditions. 相似文献

We consider a test for the equality of k population medians, θi i=1,2,….,k, when it is believed a priori, that θ i: The observations are subject to right censorhip. The distributions of the censoring variables for each population are assumed to be equal. This test is compared with the general k-sample test proposed by Breslow 相似文献

A new discrete distribution defined over all the positive integers and with the name of Geeta distribution is described. It is L-shaped like the logarithmic series distribution, Yule distribution and the discrete Pareto distribution but is far more versatile than them as it has two parameters. It belongs to the classes of location parameter distributions, modified power series distributions, Lagrange series distributions and exponential distributions. Its mean fi, variance a2 and two recurrence formulae for higher central moments are obtained. Convolution theorem and variations in the model with changes in the parameters have been considered. ML estimators, MVU estimators and estimators based of mean and variance and on mean and first frequency have been derived. 相似文献

We study a hypothesis testing problem involving the location model suggested by Olkin and Tate (1961). Specifically, we derive a likelihood ratio lest of the associated location hypothesis as an alternative to the conventional method of carrying out separate tests for each of the parameters. A small sample Monte Carlo comparison indicates the general superiority of the former in terms of statistical power. We also comment briefly on the properties of the test. 相似文献

When F = Ga, confidence intervals are derived and presented in graphs for p = P(Y < X), when X and Y are independent and the sample sizes are at most 25. Also, it is demonstrated via a monte carlo simulation that this is a robust procedure, when the distributions of X and Y differ by a location parameter. 相似文献

This paper presents an aided design methodology of flexible manufacturing system control with a view to industrial implementation. The approach considered through a modelling phase, the a validation phase by simulation and finally a distributed implementation phase. In the modelling phase, based on the Petri net formalism, we demonstrate the hierarchical aspect which separates the part flow control and the product resource control. In addition, we emphasize generic aspects which allow us to use an object-oriented approach. These aspects and the set of modelled objects are directly used in the simulation and production phases after an automatic translation in an implementation language (ADA in our case). In consequence, the distributed location for those two phases is well facilitated from the viewpoint of the approach used. 相似文献

"东欧新马克思主义"指的是第二次世界大战后在东欧国家兴起的一种马克思主义流派,其历史大体上分为两个时期:20世纪50-70年代,东欧新马克思主义作为稳定的学术派别存在,具体地说,包括南斯拉夫实践派、布达佩斯学派以及波兰和捷克斯洛伐克等国的新马克思主义;70年代后.东欧新马克思主义者作为个体融入到西方学术界,但其学术创作仍然有着东欧新马克思主义的深刻烙印.东欧新马克思主义与通常意义上的西方马克思主义以及70年代后欧美新马克思主义共同构成了20世纪新马克思主义的基本格局,其中,东欧新马克思主义鲜明的理论特色在于:其一,对马克思思想独特的、深刻的阐述;其二,对社会主义理论与实践、历史与命运的反思和对社会主义改革的理论设计;其三,对现代性的独特的理论反思. 相似文献

针对目前自主局域定向定位的需求,文中提出了一种在近场模型下反向利用阵列信号处理相关理论实现阵列自身的高精度定向定位方法,仿真实验表明该方法可以有效实现阵列的高精度定向定位.进一步对该方法的定向定位精度进行了理论分析,通过仿真分析了阵列所处位置、信号源数目、阵列自身天线阵元数目以及信号源位置存在误差时对定向定位精度的影响,相关实验结论具有重要的工程应用指导意义. 相似文献
