浅论义素分析角度观照下的英语词义演变

词的意义往往都是由词汇意义和语法意义两部分构成,其中的词汇词义时常出现变化的现象。运用义素分析法,分析英语词汇发生词义演变的类型,主要有义素增添、义素脱落、义素变更三种义素变化方式,并对词义演变方面应用的利弊进行探讨。

SIMEX estimation in case of correlated measurement errors

The simulation-extrapolation (SIMEX) approach of Cook and Stefanski (J. Am. Stat. Assoc. 89:1314–1328, 1994) has proved to be successful in obtaining reliable estimates if variables are measured with (additive) errors. In particular for nonlinear models, this approach has advantages compared to other procedures such as the instrumental variable approach if only variables measured with error are available. However, it has always been assumed that measurement errors for the dependent variable are not correlated with those related to the explanatory variables although such scenario is quite likely. In such a case the (standard) SIMEX suffers from misspecification even for the simple linear regression model. Our paper reports first results from a generalized SIMEX (GSIMEX) approach which takes account of this correlation. We also demonstrate in our simulation study that neglect of the correlation will lead to estimates which may be worse than those from the naive estimator which completely disregards measurement errors.     

Construction of neighbor designs of block size 4 for all values of v ≥ 5 by using the method of addition

In this article, a general method of construction of neighbor block designs is given. The designs are constructed using variation of a simple method which we refer to as the method of addition (renamed as the method of cyclic shifts). We give complete solution of neighbor balanced designs for k = 4 for any value of v. We also give many series of generalized neighbor designs (GNDs). In the last section, we have constructed GNDs in a sequential manner (as Did John 1981) for v ≤ 50 and r is multiple of k.     

新型农村社会养老保险基金保值增值问题研究

在梳理新农保基金管理制度现状的基础上,通过构建新农保基金收支预测模型,运用三省六县的调研数据,预测了未来新农保基金面临的贬值风险,并在分析制约新农保基金保值增值因素的基础上提出,从当下看,应切实加强新农保基金管理相关政策的落实和新的特殊政策的制定;从长远角度出发,应该逐步建立和完善新农保基金的保值增值管理体制,从委托中国社保基金管理运营逐步过渡到新农保基金的自我管理和运营。
