汉英亲属称谓中隐蔽的深层文化

汉英两种语言在亲属称谓语上有各自的民族特色和语言特征,它们存在着巨大的差异。前者丰富、复杂,而后者简单、概括。这些差异准确地映射出其背后的中西方文化不同的历史渊源与文化传统。隐蔽在汉英亲属称谓系统中的深层文化分别是由等级观念造成的长幼亲疏尊卑分明的中国文化和个人主义价值取向带来的人人平等观念的西方文化。     

Extended Family Integration Among Euro and Mexican Americans: Ethnicity,Gender, and Class

This article compares the extended family integration of Euro and Mexican American women and men and assesses the importance of class and culture in explaining ethnic differences. Using National Survey of Families and Households II data (N = 7,929), we find that ethnic differences depend on the dimension of integration. Mexican Americans exhibit higher rates of kin coresidence and proximity, but lower rates of financial support than Euro Americans. Two additional differences exist only among women: Mexican American women are more likely than Euro American women to give household or child care help. As to the explanation for these differences, social class is the key factor; cultural variables have little effect. Our findings support a theoretical framework attending to intersections among ethnicity, gender, and class.     

计算最大Lyapunov指数的推广小数据量法

在分析常用的计算最大Lyapunov指数小数据量法的基础上,研究了混沌吸引子时间轨道的不可逆特性,提出基于后向搜索和双向搜索计算最大Lyapunov指数的推广小数据量法通用经验公式。数值仿真表明,新方法比原来仅做前向搜索的小数据量法在计算准确度和抗噪声性能上更加优越。     

Generalized Sobol sensitivity indices for dependent variables: numerical methods

The hierarchically orthogonal functional decomposition of any measurable function η of a random vector X=(X₁,?…?, X_p) consists in decomposing η(X) into a sum of increasing dimension functions depending only on a subvector of X. Even when X₁,?…?, X_p are assumed to be dependent, this decomposition is unique if the components are hierarchically orthogonal. That is, two of the components are orthogonal whenever all the variables involved in one of the summands are a subset of the variables involved in the other. Setting Y=η(X), this decomposition leads to the definition of generalized sensitivity indices able to quantify the uncertainty of Y due to each dependent input in X [Chastaing G, Gamboa F, Prieur C. Generalized Hoeffding–Sobol decomposition for dependent variables – application to sensitivity analysis. Electron J Statist. 2012;6:2420–2448]. In this paper, a numerical method is developed to identify the component functions of the decomposition using the hierarchical orthogonality property. Furthermore, the asymptotic properties of the components estimation is studied, as well as the numerical estimation of the generalized sensitivity indices of a toy model. Lastly, the method is applied to a model arising from a real-world problem.     

Complete consistency for the estimator of nonparametric regression models based on extended negatively dependent errors

In this paper, we provide some exponential inequalities for extended negatively dependent (END) random variables. By using these exponential inequalities and the truncated method, we investigate the complete consistency for the estimator of nonparametric regression model based on END errors. As an application, the complete consistency for the nearest neighbour estimator is obtained.     

新时期新义衍生形成的多义词

新时期汉语新词新义项的形成出现了由既有词派生和新词派生两种并存的情形,并进而形成了旧词多义和新词多义两种多义现象。新义衍生的主要模式引申和比喻在两种多义词中呈现出不平衡性,显示出新时期新义产生的某种特点和规律。有必要在定量统计的基础上对该种现象进行分析,并对其形成的原因作出解释。     

刑法的立法解释论

刑法的立法解释作为刑法解释的一个分支,带有明显的中国特色的标签,是指最高立法机关对法律条文和法律事实所作的有权解释。在运作过程中,需要对其从三个方面加以梳理和细化:一是巩固刑法的立法解释的法理基础;二是弘扬刑法的立法解释的合目的性原则;三是界定刑法的立法解释的扩张解释方法。由此,以期达刑法恰如其分的适用之目的。     

推广的简单方程方法对两个非线性发展方程的应用

本文借助于计算机代数系统Mathematica,利用推广的简单方程方法成功获得了Joseph-Egri方程和(2+1)-维KP方程新的精确行波解,并且分别以含两个任意参数的双曲函数、三角函数及有理函数等三种形式表示,其中双曲函数表示的行波解中参数取特殊值时可得到孤波解。     

Drawing on Kinship Care Support for Older People during a Pandemic (COVID-19): Practice Considerations for Social Workers in Ghana

ABSTRACT

Undoubtedly, the ongoing COVID-19 pandemic has brought both systemic, practice changes and limitations to social workers’ commitment to the welfare of vulnerable populations such as older people. A golden preventive rule of the COVID-19 pandemic; maintaining physical and social distancing, has limited social workers’ direct practice support for older people who are considered as an at-risk population. Within jurisdictions such as Ghana where kinship care practices are culturally engrained, social workers should promote kinship care support as substitute mechanisms and pathways to safeguard or meet the welfare needs of older people.
