浅谈围堰截流和蓄水建设征地移民安置规划设计思路

在国内大中型水电站建设征地移民安置过程中,为满足电站围堰截流和蓄水阶段的移民安置要求,项目业主常提出阶段性实施移民安置任务的要求,设计单位需提出围堰和蓄水阶段建设征地移民安置规划设计专题报告。从近年国内水电项目围堰截流和蓄水等阶段性移民安置实际工作出发,分析提出了围堰截流和蓄水移民安置规划设计的概念,并从建设征地范围、实物指标、移民安置方案、农村移民安置规划、专业项目规划、投资概算、移民安置进度以及特殊措施处理等方面,提出了围堰截流和蓄水阶段性移民安置规划设计的主要设计思路,以供同仁参考。

浅谈农村移民安置方式与生产生活水平预测

水电工程移民安置方式直接关系到移民的居住权和生存权,选择切实可行的移民安置方式是移民生产生活得到保障的基础,亦是移民工作的重要内容和关键环节。移民生产生活水平预测是一个关系资源、经济、环境等多因素的复杂系统,其预测成果能否满足规划目标是判别移民安置方式是否可行的前提。目前,我国水电工程移民安置的重点在农村,不同区域的移民,生产生活现状条件差异较大,可供其选择的移民安置方式也不同,本文通过分析各种农村移民安置方式的特点,探讨其移民生产生活水平预测方法,提供一种科学选择移民安置方式的思路。

Software for Learning and for Doing Statistics

The community of statisticians and statistics educators should take responsibility for the evaluation and improvement of software quality from the perspective of education. The paper will develop a perspective, an ideal system of requirements to critically evaluate existing software and to produce future software more adequate both for learning and doing statistics in introductory courses. Different kinds of tools and microworlds are needed. After discussing general requirements for such programs, a prototypical ideal software system will be presented in detail. It will be illustrated how such a system could be used to construct learning environments and to support elementary data analysis with exploratory working style.     

A model for predicting determinants factors for NEETs rates: Support for the decision-makers

The purpose of this paper is to analyze the determining factors of the high levels of NEETs both in EU member states and in partner countries, to support policy steering and increase socio-economic cohesion. The use of longitudinal data (2005–2020) from Eurostat and World Bank databases and selected and the testing of a number of 19 factors likely to influence the rate of NEETs show us that the effectiveness of public policy solutions focused on this category of population increases when complex factors and not singular elements are targeted. From a methodological point of view, we will use MARS models and fixed effects panel models. To account for countries’ heterogeneity, these models are applied to homogeneous groups of countries, identified through cluster analysis. Social cohesion and sustainability measures for policy steering have higher chances if the action of the responsible institutions targets both meso and macro levels, if it acts not only on a factor but also on the causes that favor its manifestation. Our analysis demonstrated that the measures aimed at increasing the chances of NEETs in order to facilitate their access to education, the labor market, and social inclusion must be coordinated with those of support for combating poverty and any type of exclusion, the support given to employers (subsidizing jobs, for example), the family and the community to which the young person belongs or local authorities. Also, the research results show us that there are more common elements between countries when we analyze the factors likely to increase the rate of NEETs than when we focus on their analysis by geographical criteria, based on EU membership status or EU partner status, etc.

Techniques for defining geographic boundaries for health regions

Many federal and state programs require the geographic partitioning of states into regions for health services planning, monitoring, and/or administration. A common consideration for such programs is that region boundaries should be drawn so as to maximize the proportion of the state's population that receives health care services in its region of residence. Defining region boundaries thus may be viewed as a problem of partitioning a set of N small areal units (e.g. counties) into M subsets (regions) so as to minimize interactions (patient flow) among subsets. This paper describes three algorithms for region design and compares them in terms of computer-processing efficiency and solution value based on results from a number of test cases. Application of two of the algorithms, one based on the greedy heuristic and the other incorporating a max-flow/min-cut procedure, to a problem of dividing a metropolitan region into separate service areas for clusters of hospitals is also described.

Going for Gold: Atlanta's Bid for Fame

This article explores the importance of image to the Atlanta Olympic Games of 1996. It suggests that the event must be seen as an example of the use of the propagation of selected images designed to boost the standing of the city in an increasingly competitive interurban environment. The intersection of major sporting spectacles, big business and vastly increased television coverage provides an important new medium through which boosterists can put their city on the world map. However, as the Atlanta case reveals, the ‘semiotics of the successful city‘ involves a highly ideological construction which often presents urban areas as conflict‐free zones. In Atlanta, potentially negative images were removed both physically and symbolically from the urban landscape, while the actual experience of the Games suggested that the city had some way to go in material terms to match its often hyperbolic self‐promotion. The article suggests that the staging of events such as the Olympics is a necessarily high‐risk venture for cities, one that, as in the case of Atlanta, may not have been ultimately worth the effort. Cet article examine l'importance de l'image dans le cadre des Jeux Olympiques d'Atlanta de 1996. Il propose de considérer l'événement comme un exemple de la diffusion d'images sélectionnées, conçues et utilisées afin de promouvoir la réputation de la ville dans un contexte interurbain de plus en plus concurrentiel. L'intersection entre des spectacles sportifs exceptionnels, de grandes entreprises et une couverture télévisuelle considérablement étendue constitue un moyen novateur grâce auquel les promoteurs de cette dynamique peuvent positionner leur ville sur la carte du monde. Cependant, comme le montre le cas d'Atlanta, la ‘sémiotique d'une ville gagnante’ implique une construction idéologique très forte qui présente souvent les zones urbaines comme des espaces non conflictuels. À Atlanta, les images à potentiel négatif ont étééliminées à la fois physiquement et symboliquement du paysage urbain, tandis que les Jeux eux‐mêmes laissaient à penser que la ville devait progresser sur le plan matériel si elle voulait correspondre à son auto‐promotion souvent hyperbolique. L'article suggère que la mise en scène d'événements tels que les Jeux Olympiques est une opération nécessairement très risquée pour des villes, opération qui, à l'instar de l'expérience d'Atlanta, peut finalement ne pas justifier les efforts réalisés.     

Distribution-free Approximate Methods for Constructing Confidence Intervals for Quantiles

Quantile estimation is important for a wide range of applications. While point estimates based on one or two order statistics are common, constructing confidence intervals around them, however, is a more difficult problem. This paper has two goals. First, it surveys the numerous distribution-free methods for constructing approximate confidence intervals for quantiles. These techniques can be divided roughly into four categories: using a pivotal quantity, resampling, interpolation, and empirical likelihood methods. Second, a method based on the pivotal quantity that has received limited attention in the past is extended. Comprehensive simulation studies are used to compare performance across methods. The proposed method is simple and performs similarly to linear interpolation methods and a smoothed empirical likelihood method. While the proposed method has slightly wider interval widths, it can be calculated for more extreme quantiles even when there are few observations.     

Change point test for tail index for dependent data

To test for the constancy of tail index, Quintos et al. (Rev Econ Stud 68:633–663, 2001) proposed three types of change point tests for independent and ARCH type sequences. In this paper, we demonstrate that their tests can be successfully extended to a large class of dependent stationary sequences. Further, we designate a time-reverse version of those tests since the original tests produce very low powers in case the tail of distribution gets thinner. A simulation study is implemented for illustration.
