Elder Abuse in Residential Settings in Israel—Myth or Reality?

ABSTRACT

The article tries to answer the question: Is elder abuse in residential care in Israel a myth or a reality? A broad definition of abuse was used, including the ‘classical’ forms presented in the literature, and also violation of rights and any act that infringes on quality of life of residents. As no data exist which directly explored this issue, the analysis was based on: recent laws mandating the report of abuse, governmental surveillance data, court cases, media clippings, and data from quality of life studies. Findings reveal that abuse in its ‘classical’ form exists only in a limited number of small private unlicensed facilities. However, when using the broader definition, abuse is a reality in many settings, exercised mainly by nurses' aides.     

On LSE in regression model for long-range dependent random fields on spheres

We study the asymptotic behaviour of least squares estimators (LSE) in regression models for long-range dependent random fields observed on spheres. The LSE can be given as a weighted functional of long-range dependent random fields. It is known that in this scenario the limits can be non-Gaussian. We derive the limit distribution and the corresponding rate of convergence for the estimators. The results were obtained under rather general assumptions on the random fields. Simulation studies were conducted to support theoretical findings.     

Measures of dependence for the multivariate t distribution with applications to the stock market

Two measures of dependence for multivariate t and Cauchy random variables are developed based on Kullback–Leibler number. The mutual information number T(X) is obtained in a closed expression form, as well as its asymptotic distribution. A dependence coefficient ρ₁, is defined (based on the Kullback–Leibler number) with the properties of ρ₁=0 indicating independence and ρ₁=1indicating degeneracy. Two real life examples from the stock market are used to analyze the level of dependence and correlation among stocks.     

A Copula‐Based Non‐parametric Measure of Regression Dependence

Abstract. This article presents a framework for comparing bivariate distributions according to their degree of regression dependence. We introduce the general concept of a regression dependence order (RDO). In addition, we define a new non‐parametric measure of regression dependence and study its properties. Besides being monotone in the new RDOs, the measure takes on its extreme values precisely at independence and almost sure functional dependence, respectively. A consistent non‐parametric estimator of the new measure is constructed and its asymptotic properties are investigated. Finally, the finite sample properties of the estimate are studied by means of a small simulation study.

“语言是一种符号系统”说疑议

文章简要概括了索绪尔“语言是一种符号系统”说,认为索氏那种研究语言而“不管历时态”的学说,就认识论而言乃是机械唯物主义的,就方法论而言是形而上学的,落实到实践上则是行不通的。文中立足汉语研究之现实,以典型事例印证了索氏之说的误导作用。进而对索氏理论的基石“能指和所指的联系是任意的”说进行验证,发现它的提出主要是出于理论建构的需要,但同时也不可避免地暴露了索氏理论的臆断性。文章的结论是:“语言是一种符号系统”说的观念是浮泛的,它对汉语研究的负面影响是严重的。     

Testing the Martingale Difference Hypothesis

In this paper we consider testing that an economic time series follows a martingale difference process. The martingale difference hypothesis has typically been tested using information contained in the second moments of a process, that is, using test statistics based on the sample autocovariances or periodograms. Tests based on these statistics are inconsistent since they cannot detect nonlinear alternatives. In this paper we consider tests that detect linear and nonlinear alternatives. Given that the asymptotic distributions of the considered tests statistics depend on the data generating process, we propose to implement the tests using a modified wild bootstrap procedure. The paper theoretically justifies the proposed tests and examines their finite sample behavior by means of Monte Carlo experiments.     

Continuous-Time Stochastic Processes with Cyclical Long-Range Dependence

This paper introduces continuous‐time random processes whose spectral density is unbounded at some non‐zero frequencies. The discretized versions of these processes have asymptotic properties similar to those of discrete‐time Gegenbauer processes. The paper presents some properties of the covariance function and spectral density as well as a theory of statistical estimation of the mean and covariance function of such processes. Some directions for further generalizations of the results are indicated.     

农户分化、乡土依赖与集体收益分配权退出

基于3个农村改革试验区716个农户的微观数据,实证分析农户分化、乡土依赖对农户集体收益分配权退出意愿的影响。结果表明,农户的不断分化并未提高其集体收益分配权退出意愿,分化程度较高的农户更倾向于继续持有集体收益分配权,土地、宅基地的退出对集体收益分配权退出意愿未产生显著影响,但对所在村的心理依赖水平有着显著的反向影响,即在集体收益分配权的退出中,对其退出意愿产生影响的更多是农户对乡土的心理依赖,而非现实依赖。这要求在进一步探索中,既要有改革的紧迫感,完善退出机制,引导符合条件的农户理性退出集体收益分配权,也要有历史的耐心,充分尊重农户的乡土情结。     

相关性下的银行风险集成研究综述

银行风险之间的相关关系会使风险之间相互转化,相互影响,令风险呈现出放大或者缩小的趋势,显著影响着银行风险度量结果的准确性。银行风险集成致力于在充分考虑银行风险相关关系的基础上,对银行风险进行较为准确的度量。但是银行风险具有相关关系种类繁多、表现形式复杂、以及数据的可获得性差等显著特征,导致银行风险的集成度量领域存在诸多挑战。本文对相关性下的银行风险集成研究进行综述,具体从集成对象、集成方法和集成数据三个层次系统展开。首先对银行风险及其蕴含的种类繁多的相关关系类型进行解析,然后分析银行风险相关关系表征出的多种复杂特性,根据对这些特性的刻画能力对银行风险的集成方法进行划分和比较,最后总结了获取银行风险集成数据的多种途径。在此基础上,进一步分析了银行风险集成研究的难点和未来趋势。
