This work deals with estimating the vector of means of certain characteristics of small areas. In this context, a unit level multivariate model with correlated sampling errors is considered. An approximation is obtained for the mean-squared and cross-product errors of the empirical best linear unbiased predictors of the means, when model parameters are estimated either by maximum likelihood (ML) or by restricted ML. This approach has been implemented on a Monte Carlo study using social and labour data from the Spanish Labour Force Survey. 相似文献

日本的大学在国家科技发展战略中处于前沿位置,政府将科技研究与开发经费中相当大的部分投入到了大学,并为此设计、调整了相关政策。竞争性科研经费制度的建立,透射出日本政府行政改革和高等教育改革的背景,反映了日本国家科技战略对大学科研功能的重视和依赖。科研经费竞争性投放对大学的创新性科学研究具有重要的引导作用和助推作用。 相似文献

正义是人类自古以来永恒不舍的追求,在全球环境日益恶化的今天,需要新的正义价值理念引领,环境正义应运而生。环境正义就是要求人类在处理环境危机时做到环境权利与环境义务的公平合理的分配与承担,以求整个人类共存与可持续发展。本研究立足于分析当前国际环境正义存在的问题,提出了我国在国际环境正义建设中应采取的对策。 相似文献

二十世纪八十年代之后,以"跨文化沟通教育体系""多元文化整合教育理论"为标志,中国人类学者从全球、国家、地方三个层面开始系统探讨学校教育与共同体建设问题.以二十一世纪之后的民族文化/非物质文化遗产进校园的实践为标志,国家通过学校教育传承地方知识培育学生的地方文化认同进而培育中华民族共同体意识.纵观百余年来中国学校教育塑造国家共同体的理论实践,其核心问题就是学校教育中的文化选择、整合与传递问题.要构建中国教育人类学的理论体系和话语体系,为铸牢中华民族共同体意识提供理论支撑. 相似文献

ABSTRACTWe consider the problem of parameter estimation by the observations of the inhomogeneous Poisson processes. We suppose that the intensity function of these processes is a smooth function of the unknown parameter and as a method of estimation we take the minimum distance approach. We are interested by the behavior of estimators in non Hilbertian situation and we define the minimum distance estimation (MDE) with the help of the Lp metrics. We show that (under regularity conditions) the MDE is consistent and we describe its limit distribution. 相似文献

Gibbs point processes (GPPs) constitute a large and flexible class of spatial point processes with explicit dependence between the points. They can model attractive as well as repulsive point patterns. Feature selection procedures are an important topic in high-dimensional statistical modeling. In this paper, a composite likelihood (in particular pseudo-likelihood) approach regularized with convex and nonconvex penalty functions is proposed to handle statistical inference for possibly high-dimensional inhomogeneous GPPs. We particularly investigate the setting where the number of covariates diverges as the domain of observation increases. Under some conditions provided on the spatial GPP and on penalty functions, we show that the oracle property, consistency and asymptotic normality hold. Our results also cover the low-dimensional case which fills a large gap in the literature. Through simulation experiments, we validate our theoretical results and finally, an application to a tropical forestry dataset illustrates the use of the proposed approach. 相似文献

The purpose of the present study was to investigate sociodemographic variables, features of sexual abuse (SA), and first psychiatric evaluation results of abused children, and to analyze the relation of the psychiatric evaluation results to the children’s age and gender, type and duration of abuse, abuser–child relationship, and marital status of the children’s parents, at one of the most experienced Child Advocacy Centers (CACs) in Turkey. All data were obtained from reports prepared by child and adolescent psychiatrists. The sample of this study consists of 436 child sexual abuse (CSA) cases who admitted ?zmir CAC between April 2014 and November 2015. The statistical analyses yielded significant relations between psychiatric symptoms and chronic abuse, the gender of the children, and type of abuse. Suicidal ideation and behaviors due to sexual abuse (SA) were also examined. According to our results, it is fair to say that children exposed to SA benefit from immediate psychiatric help because of their vulnerability for psychiatric disorders due to abuse. In this context, CACs are very important multidisciplinary establishments to determine children’s multiple needs to ease their trauma with collaborative teamwork. Psychiatric evaluation should be part of this multidisciplinary context. 相似文献
