For longitudinal time series data, linear mixed models that contain both random effects across individuals and first-order autoregressive errors within individuals may be appropriate. Some statistical diagnostics based on the models under a proposed elliptical error structure are developed in this work. It is well known that the class of elliptical distributions offers a more flexible framework for modelling since it contains both light- and heavy-tailed distributions. Iterative procedures for the maximum-likelihood estimates of the model parameters are presented. Score tests for the presence of autocorrelation and the homogeneity of autocorrelation coefficients among individuals are constructed. The properties of test statistics are investigated through Monte Carlo simulations. The local influence method for the models is also given. The analysed results of a real data set illustrate the values of the models and diagnostic statistics. 相似文献

AbstractDuring 2009, the Hilton M. Briggs Library, South Dakota State University, went live with MetaLib, a federated search engine from Ex Libris. This paper presents the implementation process, addresses resource accessibility issues, and suggests a number of resources that can be consulted about these issues. Readers can apply similar strategies to projects involving federated search systems, as many implementation projects involve the same basic considerations presented here. The author did not find any studies specifically focused on configurations of MetaLib resources, so this content should be singularly useful. 相似文献

恢复性司法理念下我国刑事和解制度的构建 总被引:1,自引:0,他引:1
李綦通 《北京理工大学学报(社会科学版)》2010,12(4):92-97
国历史上和现代的刑事和解实践无法实现恢复性司法的目标。针对这一问题,运用历史考察和比较研究的方法,对我国刑事和解制度的发展进行了梳理,对我国刑事和解与恢复性司法进行了比较。我国的刑事和解在适用模式、适用范围和结果方面与恢复性司法存在一定的差别。我国刑事和解制度的构建应该以联合国预防犯罪和刑事司法委员会《关于在刑事事项中采用恢复性司法方案的基本原则》为参照,在适用范围、和解结果等方面达到恢复性司法的目标。 相似文献

In this paper, we empirically assess the role of individual social capital on personal bankruptcy and default outcomes in the consumer credit market. After controlling for a borrower’s risk score, debt, income, wealth, and legal and economic environments, we find that default/bankruptcy risk rises and then falls over the lifecycle, while a borrower who owns a home or is married has a lower risk of default/bankruptcy. Moreover, a borrower who migrates 190 miles from his “state of birth” is 17% more likely to default and 15% more likely to file for bankruptcy, while a borrower who continues to live in his state of birth is 14% and 10% less likely to default and file for bankruptcy, respectively. A borrower who moves to a rural area is 9% and 7% less likely to default and declare bankruptcy, respectively. We also find that measures of social networks, norms, and cooperation and trust (i.e., aggregate social capital) are inversely related to consumer bankruptcy. 相似文献

Abstract This article addresses the relationship between language and identity and language and power. Language is viewed as an important vehicle through which empowerment can occur in society and through which social workers can contribute to the empowerment of dual language individuals and communities. Language suppression is viewed through the framework of bilinguaphobia, a term coined by Faltis and Coulter in 2004. Because of the long and unique history of Spanish in Southwestern communities, the authors suggest that true empowerment must overcome the prevalent discourse of fear of bilingualism. This article suggests that the present status and identity of Latinos in the Southwestern United States would be enhanced and affirmed by the healthy co-existence of two tongues and two cultural frameworks and that social workers should recognize and advocate for the power of bilingual discourses. 相似文献

同隐喻一样,借代也是一种重要的思维方式和认知工具.然而,长期以来,借代研究仍然拘泥于修辞范畴,其功能得不到充分体现.本文从认知角度出发,在引入理想化认知模型(ICM)的基础上对借代的工作机制进行重新探讨和认识,同时对其在语篇连贯和衔接方面所发挥的重要作用也进行了初步研究. 相似文献

Social skills and symbol skills are positively associated in middle childhood, but the relation between these domains is less clear in newly verbal toddlers. Vygotsky proposed that symbols are both tools for interaction and mental tools for thought. Do symbols help even very young children build skills for interacting with and conceptualizing the social world? Longitudinal data from 108 children and mothers were collected when children were 14, 24, and 36 months. Children's gestures and words during mother–child interactions were used as symbol skill indicators to predict children's abilities to engage others and the number of social‐emotional concepts children portray during play. In a series of growth models, words had a stronger effect on engagement skills whereas early gesture use predicted later development of social‐emotional concepts. Therefore, even in early development, symbols serve as both communication tools and mental tools to construct understanding of the social‐emotional world. 相似文献

在自然语言处理中,神经网络模型(ANN)比符号主义方法更加接近人脑处理语言的实际心理加工机制。神经网络模拟可检验“语言加工双重路线”、“语言初始状态”等假设有效性;语言认知心理机制研究也会对神经网络构建起促进作用。语言认知机制研究应从追求简单的脑区定位发展到脑区间互动以及脑内语言信息加工的时空网络建模。 相似文献

Objective.?Low total testosterone levels (TT) have been associated with increased morbidity and mortality. However, the prevalence and incidence of testosterone deficiency (TD) in association with its risk has not been assessed systematically to date.Methods.?Data from the prospective population-based Study of Health in Pomerania were used. From the 2117 men aged 20–79 years at baseline, 1490 men with complete TT data were analysed. Crude and age-specific prevalence and incidence rates of TD were estimated by TT levels below the age-specific 10th percentile. Analysis of covariance and Poisson regression models were used to assess the association of socio-demographic characteristics, health-related lifestyle, as well as somatometric, medical and laboratory measures with risk of incident TD.Results.?TD baseline prevalence was 10.4% (N?=?155) and incidence 11.7 per 1000 person-years. TT levels showed a significant age-related decline with an unadjusted rate of 0.05 nmol/l per year. Obesity, metabolic syndrome, diabetes and dyslipidaemia were identified as risk factors of incident TD. Subpopulations of men without the revealed risk factors at both examinations maintained constant TT levels over time.Conclusions.?Besides aging alone, lifestyle and different comorbidities were associated with TT level decline, suggesting that the age-related TT decline may be at least partly prevented through the management of potentially modifiable risk factors and health related behaviour. 相似文献
