论城市房屋拆迁侵权类型及其责任方式

由于城市化进程的发展,我国的城市房屋拆迁行为愈渐频繁。由于政府在拆迁行为过程中角色的错位,未按照法定程序以及开发商的补偿不合理等原因导致的侵权行为愈演愈烈。新的《物权法》已经出台并付诸于实施,在这一新的法律制度环境下,如何去规制拆迁行为中的秩序,维护相对方的利益,明确各方责任将是本文着重探讨的重点。     

Generally weighted moving average control charts with fast initial response features

The generally weighted moving average (GWMA) control chart is an extension model of exponentially weighted moving average (EWMA) control chart. Recently, some approaches have been proposed to modify EWMA charts with fast initial response (FIR) features. We introduce these approaches in GWMA-type charts. Via simulation, various control schemes are designed and then their average run lengths are computed and compared. Based on the overall performance, it is showed that the DGWMA chart is the best choice especially when the shift is moderate, and the GWMA charts provided with additional FIR feature have a good performance only in detecting large shifts during the initial stage.     

“动态镜头”、“运动镜头”、“运动摄像”及相关概念辨析

在关于电视画面运动的讨论中,有好几个概念都存在彼此牵连、界定不清的问题。为了廓清思路,更好地指导实践,可从拍摄的角度起用一个新概念——“固定拍摄”,以便与传统的“运动摄像”概念形成呼应;从后期剪辑的角度,则可以起用一对新概念——“静态镜头”和“动态镜头”,以适应观众对画面的把握方式;同时,对传统的一对概念“固定镜头”和“运动镜头”相应地需要进行更准确的定位和把握。最后,对与“运动摄像”相关的一系列容易让人误解的传统概念、术语也进行了更为细致的辨别。     

一种简单有效的二项分布比例参数似然比置信区间的求法

对二项分布比例参数p的似然比置信区间,提出一种简便求解方法。在平均覆盖率、平均区间长度及区间长度的95%置信区间准则下与WScore、Plus4、Jeffreys置信区间进行模拟比较。试验表明,在二项分布b(n,p)的参数n≥20且p∈(0.1,0.9)时,该方法获取的似然比置信区间性能优良。当点估计p值不是接近于0或1且n≥20时,推荐使用本方法获取p的置信区间。     

New V control chart for the Maxwell distribution

Control charts have been popularly used as a user-friendly yet technically sophisticated tool to monitor whether a process is in statistical control or not. These charts are basically constructed under the normality assumption. But in many practical situations in real life this normality assumption may be violated. One such non-normal situation is to monitor the process variability from a skewed parent distribution where we propose the use of a Maxwell control chart. We introduce a pivotal quantity for the scale parameter of the Maxwell distribution which follows a gamma distribution. Probability limits and L-sigma limits are studied along with performance measure based on average run length and power curve. To avoid the complexity of future calculations for practitioners, factors for constructing control chart for monitoring the Maxwell parameter are given for different sample sizes and for different false alarm rate. We also provide simulated data to illustrate the Maxwell control chart. Finally, a real life example has been given to show the importance of such a control chart.     

Monitoring the coefficient of variation using a variable sample size and sampling interval control chart

This article proposes a CV chart by using the variable sample size and sampling interval (VSSI) feature to improve the performance of the basic CV chart, for detecting small and moderate shifts in the CV. The proposed VSSI CV chart is designed by allowing the sample size and the sampling interval to vary. The VSSI CV chart's statistical performance is measured by using the average time to signal (ATS) and expected average time to signal (EATS) criteria and is compared with that of existing CV charts. The Markov chain approach is employed in the design of the chart.     

日本对中国文化的摧残与中国文化重心西移之历史考察

日本帝国主义侵华期间对中国文化进行肆意摧残,为了保存中华民族的文化精华,中国东部地区的重要高等院校、文物国宝、重要报刊等文化机构、文化设施及文化团体,尤其是大批文化名人,纷纷内迁西移,这在实际上形成了中国文化重心西移的历史壮举。它不仅保存了中华民族的文化精华和精英,而且大大改变了西部文化的落后状况,对今天的西部文化大开发也有重要启示和借鉴。

A hybrid approach to configure eco-efficient supply chains under consideration of performance and risk aspects

Formal models that support multi-criteria decision making represent a strongly growing area in sustainable supply chain management research. However, uncertainties and risks are seldom considered in quantitative models for green supply chain (SC) design. The paper at hand suggests a hybrid approach to configure an eco-efficient SC for a new product under consideration of economic and environmental risks. Discrete-event simulation is applied to assess the financial, operational and environmental performance of different SC configuration options while the value-at-risk concept is adapted to evaluate related SC risks. The analytic hierarchy process is employed to solve the resulting multi-criteria decision problem of choosing the best option. The approach is illustrated at a case example of a fast moving consumer goods manufacturer.
