加强和改进扶贫项目的监测与评估——基于泰国村庄基金的思考

扶贫开发是坚持以人为本科学发展观的具体体现,是构建社会主义和谐社会的重要内容,是全面建设小康社会和建设社会主义新农村的一项重要任务。我国的扶贫开发工作取得了显著的成效,但也存在着突出的问题。泰国村庄基金是一个很成功的扶贫项目,"它山之石,可以攻玉"。     

Some comments on sample quantiles for dependent observations

Sample quantiles obtained from a linear process are examined and their asymptotic properties are derived by using simple elementary arguments.     

Spreadsheet Analysis in Human Services

Abstract

Computerized spreadsheets were developed to support accounting functions, but these programs have come to have much broader applications. This chapter introduces spreadsheet analysis, briefly explains key concepts used in creating spreadsheets, and finally gives examples from direct practice and human service administration. While spreadsheets can be used for any task that requires manipulation of numbers or use of a calculator, they are most useful in producing charts and tables and for modeling problems requiring “what if” projections.     

圆筒形件拉深过程的力学理论分析与计算

本文应用塑性力学理论分析了拉深变形过程,根据拉深变形的实际情况,建立了位移和凸缘半径之间的关系,然后从轴对称变形几何方程出发,求出了拉深变形的应变与凸缘半径之间的关系,并通过该关系求得了等效应变,确定了真实应力应变关系模式,从而求解出了拉深力.     

网络教育的学习监控探析

网络学习已成为一种非常重要的教育模式，如何使网络学习高质、高效的发展成为网络教育面临的重要问题，解决这一问题的关键是施加必要的学习监控。通过分析网络学习监控的必要性，笔者认为对网络学习施加学习监控是一个从外部监控，到慢慢减少外部监控，再到完全自主监控这样一个循序渐进的过程。在具体实施学习监控的手段上，一方面提出应采取学业评价和电子学档等手段进行外部监控的支持，另一方面着重对网络学习自主监控的问题和策略进行了阐述。

Space–time calibration of radar rainfall data

Motivated by a specific problem concerning the relationship between radar reflectance and rainfall intensity, the paper develops a space–time model for use in environmental monitoring applications. The model is cast as a high dimensional multivariate state space time series model, in which the cross-covariance structure is derived from the spatial context of the component series, in such a way that its interpretation is essentially independent of the particular set of spatial locations at which the data are recorded. We develop algorithms for estimating the parameters of the model by maximum likelihood, and for making spatial predictions of the radar calibration parameters by using realtime computations. We apply the model to data from a weather radar station in Lancashire, England, and demonstrate through empirical validation the predictive performance of the model.

On the estimation of the marginal density of a moving average process

The authors present a new convolution‐type kernel estimator of the marginal density of an MA(1) process with general error distribution. They prove the √n; ‐consistency of the nonparametric estimator and give asymptotic expressions for the mean square and the integrated mean square error of some unobservable version of the estimator. An extension to MA(q) processes is presented in the case of the mean integrated square error. Finally, a simulation study shows the good practical behaviour of the estimator and the strong connection between the estimator and its unobservable version in terms of the choice of the bandwidth.     

Intensity Estimation for Spatial Point Processes Observed with Noise

Abstract.  This article introduces a kernel estimator of the intensity function of spatial point processes taking into account location errors. The asymptotic properties of the estimator are derived and a bandwidth selection procedure is described. A simulation study compares our results with that of the classical kernel estimator and shows that the edge-corrected deconvoluting kernel estimator is more appropriate.
