论行政人的从政道德建设——以人性和欲望为基点

随着改革开放和市场经济的发展，虽然带来了社会的发展和人性的解放，同时也对行政人造成了一定冲击。一些干部滑坡、以权谋私等现象依然存在，这些问题与行政人的从政道德密切相关。因此，本文围绕行政人的从政道德建设，从人性和欲望的角度出发，提出一些可供参考的思路。     

塔里木河中游地区草湖环境的演变——基于清末至民国草湖纠纷事件的讨论

清末至民国,发生在塔里木河中游地区的三起草湖纠纷事件,反映了草湖地区的人地关系趋于紧张.经过研究,我们发现引起草湖纠纷的因素来自于平原绿洲区,即快速增长的人口及其不断增长的需求对草湖环境产生了极大的压力.草湖地区人类不合理的开发活动,加剧了塔里木河汊流的发育,使塔里木河水散失日益严重,最终造成草湖环境的不断退化;甚至酿成了1921年塔里木河下游河道的改道.     

试析《逃离》中弗洛拉的神话隐喻

艾丽丝·门罗的短篇小说《逃离》,表面上书写的是在中年危机和琐碎中挣扎的女性,展示的是卡拉的欲望和遗憾,坚强和软弱.实际上门罗通过借用古希腊神话和《圣经》典故,将小说中的女性与神话意象相互联系.通过分析门罗小说中具有代表性的原型——山羊弗洛拉,发掘出原型背后小说的意义,同时加深对门罗女性观的理解.     

Fractional Brownian motion and clinical trials

The purpose of this paper is to extend the widely used classical Brownian motion technique for monitoring clinical trial data to a larger class of stochastic processes, i.e. fractional Brownian motion, and compare these results. The beta-blocker heart attack trial is presented as an example to illustrate both methods.     

CO-tucker: a new method for the simultaneous analysis of a sequence of paired tables

Relationships between species and their environment are a key component to understand ecological communities. Usually, this kind of data are repeated over time or space for communities and their environment, which leads to a sequence of pairs of ecological tables, i.e. multi-way matrices. This work proposes a new method which is a combined approach of STATICO and Tucker3 techniques and deals to the problem of describing not only the stable part of the dynamics of structure–function relationships between communities and their environment (in different locations and/or at different times), but also the interactions and changes associated with the ecosystems’ dynamics. At the same time, emphasis is given to the comparison with the STATICO method on the same (real) data set, where advantages and drawbacks are explored and discussed. Thus, this study produces a general methodological framework and develops a new technique to facilitate the use of these practices by researchers. Furthermore, from this first approach with estuarine environmental data one of the major advantages of modeling ecological data sets with the CO-TUCKER model is the gain in interpretability.

通过顾客价值理论分析,商业经营现象抽象和商业发展历史考证得出:提升顾客价值就是增加顾客效用和降低顾客成本;商业经营实质就是降低顾客成本,商业发展历史就是降低顾客成本的演变史;认识降低顾客成本规律是商业经营和发展的创新思维,是商业经营理念和经营方针的深化和创新。     

Asymptotic Distribution of the Estimated BDS Statistic from The Residuals of Location-Scale Type Processes

We introduce local asymptotic normality (LAN) for the log-likelihood ratio and the contiguity property of a class of location-scale processes in this paper. Using the contiguity property, we study the asymptotic distribution of the estimated Brock-Dechert-Scheinkman (BDS) statistic from the standardized residuals of fitting location-scale type processes.     

Urban poverty and labor market dynamics in five Latin American countries: 2003–2008

Latin America experienced a long period of sustained growth since 2003 that positively impacted social and labor market indicators, including poverty. This paper contributes to the understanding of this process as it carries out a comparative study of poverty dynamics in five Latin American countries during 2003–2008. It analyzes the extent to which countries with different levels of poverty incidence diverge in terms of poverty exit and entry rates, identifies the relative importance of the frequency and impact of events associated to poverty transitions and examines how these events affect households with different characteristics. For this, a dynamic analysis of panel data is carried out using regular household surveys. Sizeable rates of poverty movements were observed in all five countries and it was found that a large proportion of household experienced positive events, mainly related to the labor market; however, only a small fraction of them actually exited poverty. Demographic events and public cash transfers proved to be of little relevance; in particular, the latter did not contribute much either to intensify poverty exits or to prevent poverty entries. Households with children experienced more (less) negative (positive) events than those without children. It appeared therefore that even when the economy behaved reasonably well at the aggregate level, high levels of labor turnover and income mobility (even of a negative nature) still prevail, mainly associated to the high level of precariousness and the undeveloped system of social protection that characterize the studied countries.     

Using Weight Functions in Spatial Point Pattern Analysis with Application to Plant Ecology Data

This paper presents procedures for percentile estimation in the three-parameter inverse Gaussian (IG3) and the two-parameter inverse Gaussian (IG2) distributions. All procedures require first the estimation of distribution parameters and second the computation of the desired quantile at the estimated parameters. Parameter estimation is accomplished by maximum likelihood (ML) or a mixed moments (MXM) method. A Newton-Rahpson (NR) procedure is used for inverting the CDF. Simulation and asymptotic results are given for the resulting estimators. Two sets of real data are used to illustrate the procedures.
