幼儿冒险游戏水平与抗挫折能力的关系：自我效能感的中介作用

为考察幼儿冒险游戏水平与抗挫折能力的关系,及考察自我效能感在两者关系中的中介作用,本研究随机选取浙江省杭州市148名幼儿为被试,通过任务测评法评定幼儿的冒险游戏水平和自我效能感,通过教师问卷评定报告幼儿的抗挫折能力。结果表明：幼儿冒险游戏水平、自我效能感、抗挫折能力发展良好;冒险游戏水平直接正向预测抗挫折能力,并通过自我效能感间接预测抗挫折能力。

日本红十字会参与疫情危机应对的机制及启示

新冠肺炎疫情发生后,中国社会各界积极踊跃捐赠款物,体现了中华民族“一方有难、八方支援”的大爱精神。在此次新冠肺炎疫情防控中,地方政府依循惯例,迅速指定省、市红十字会和慈善总会作为接受社会捐助的专责机构,发挥了重要作用。然而,疫情重灾区湖北、武汉的红十字会却暴露出救援物资分配不均、捐赠收取管理费等问题。本文从国际比较视野出发,选取日本红十字会为研究对象,采取政策文本分析等研究方法,考察日本红十字会的疫情防控参与机制与捐赠款物分配机制,并提出对中国的若干启示。

An elastic-net penalized expectile regression with applications

To perform variable selection in expectile regression, we introduce the elastic-net penalty into expectile regression and propose an elastic-net penalized expectile regression (ER-EN) model. We then adopt the semismooth Newton coordinate descent (SNCD) algorithm to solve the proposed ER-EN model in high-dimensional settings. The advantages of ER-EN model are illustrated via extensive Monte Carlo simulations. The numerical results show that the ER-EN model outperforms the elastic-net penalized least squares regression (LSR-EN), the elastic-net penalized Huber regression (HR-EN), the elastic-net penalized quantile regression (QR-EN) and conventional expectile regression (ER) in terms of variable selection and predictive ability, especially for asymmetric distributions. We also apply the ER-EN model to two real-world applications: relative location of CT slices on the axial axis and metabolism of tacrolimus (Tac) drug. Empirical results also demonstrate the superiority of the ER-EN model.     

Variance estimation based on blocked 3×2 cross-validation in high-dimensional linear regression

In high-dimensional linear regression, the dimension of variables is always greater than the sample size. In this situation, the traditional variance estimation technique based on ordinary least squares constantly exhibits a high bias even under sparsity assumption. One of the major reasons is the high spurious correlation between unobserved realized noise and several predictors. To alleviate this problem, a refitted cross-validation (RCV) method has been proposed in the literature. However, for a complicated model, the RCV exhibits a lower probability that the selected model includes the true model in case of finite samples. This phenomenon may easily result in a large bias of variance estimation. Thus, a model selection method based on the ranks of the frequency of occurrences in six votes from a blocked 3×2 cross-validation is proposed in this study. The proposed method has a considerably larger probability of including the true model in practice than the RCV method. The variance estimation obtained using the model selected by the proposed method also shows a lower bias and a smaller variance. Furthermore, theoretical analysis proves the asymptotic normality property of the proposed variance estimation.     

Producing mobility: visual narratives of the rural migrant worker in Chinese television

This paper employs literatures of mobility to explore the ways which rural migrant workers in China are represented publicly via television drama. Through an analysis of the popular serial Mingong, the paper examines the underlying politics of contemporary migration in China through three themes: the territorialisation of rural and urban spaces; the embodiment of boundaries via corporeal practices and subjectivities; and the politicisation of rural migrant desires. This analysis demonstrates the significance of television in crafting discursive understandings of mobility and migrants that are suffused with contemporary governmentalities of generating but also managing and excluding migration.     

翻译理论视角下的戏剧剧本翻译及原则

随着中外文化交流的日渐频繁与深入,中国要向世界展现华夏文明和中国文化,而戏剧正是文化的精髓。我国有丰富的剧种和曲目繁多的优秀剧目,要有效地展现中国文化就要让优秀剧目跨出国门尽显中国戏剧的魅力。然而由于戏剧剧本的内容有大量的文言句式和诗词曲赋,在翻译中要有效地传递诗词曲赋的意象美面临很多挑战。同时,戏剧剧本的内容中还有大量的古代典故和戏剧术语,这些对于中国人都陌生的中国元素要有效地传递给全世界的朋友就需要有高质量的翻译。翻译的高质量需要有效翻译理论的指导,文章尝试用翻译剧本为例,阐述翻译理论指导下的戏剧剧本翻译的翻译原则。

Family Characteristics and Mate Selection: Evidence From Computer‐Assisted Dating in Japan

Research on mate selection rarely considers singles' preferences for their future partners' family configurations and experiences. Using online dating records from a matchmaking agency in Japan, a society with a strong emphasis on family and kinship, we examine how singles' responses to date requests correspond to potential mates' family circumstances. Results showed that singles' preferences for potential partners' family characteristics stem from a concern about future obligations toward the partner's family and stereotypes associated with certain family traits. Singles are less likely to accept requests from those from large families, which are seen as traditional. Being from a large family, however, hampers individuals' dating chances more if they are firstborn and have no brothers, two conditions that make them the designated child to care for elderly parents. We also find that Japanese singles seek partners with more of the universally valued family traits rather than traits similar to their own.
