新中国夫妻财产制立法的检视与思考

新中国夫妻财产制立法分为三个阶段:以1950年婚姻法为标志的初创阶段、以1980年婚姻法为标志的渐进发展阶段和以2001年现行婚姻法修改为标志的逐步完善阶段.新中国成立后的前30年,夫妻财产制在立法模式和实质内容上都深受前苏联的影响,突出表现为婚姻法一直独立于民法典采单行法形式、夫妻财产制始终采共同财产制且内容简略等特点;1980年以来的后30年,我国开始逐渐摆脱前苏联的影响,走上了一条兼容并蓄、自主立法的道路.当前,我国夫妻财产制急需全面提升充实,首先应确立包括男女实质平等、个人财产保护、交易安全等原则在内的多元价值理念,其次应从立法体例上推动亲属法回归民法,促进夫妻财产制立法的发展,最后应充实完善夫妻财产制的一系列基本制度内容.     

论汉语零句的语义表达

汉语中的零句在汉语语法中具有重要作用.语义表达是零句研究的重要组成部分之一.汉语零句的语义表达看似简单,但仍有其深层次的严谨的语法关系,文章从语法研究的三个平面(句法、语义、语用)入手,揭示并概括出零句多种多样的语义表达.另外,本文的研究成果还有助于为零句研究添砖加瓦.     

带有市场交易信息和随机微观噪声下的杠杆效应研究

在风险管理中杠杆效应的现象广泛存在，也是金融计量学中的重要议题。高频金融市场中蕴含着丰富的交易信息，而这些信息并不能都看作随机噪声，因此探讨利用市场交易信息并在带有随机噪声模型下研究杠杆效应具有重要意义。本文在带有市场交易信息和随机微观噪声相结合的模型下研究了杠杆效应，提出了新的杠杆效应估计，该估计具有n^1/8的收敛速度，同时给出了估计的方差和相关的定理。通过模拟分析得出利用广泛的市场微观信息可以更有效和更精确地对杠杆效应进行估计，模拟的结果表明本文提出的杠杆效应估计具有更好的渐近正态性和更小的偏差。最后将提出的估计应用到实证分析中，发现杠杆效应对未来一天波动率的预测具有显著性影响。

Two-sample high-dimensional empirical likelihood

In this paper, we apply empirical likelihood for two-sample problems with growing high dimensionality. Our results are demonstrated for constructing confidence regions for the difference of the means of two p-dimensional samples and the difference in value between coefficients of two p-dimensional sample linear model. We show that empirical likelihood based estimator has the efficient property. That is, as p → ∞ for high-dimensional data, the limit distribution of the EL ratio statistic for the difference of the means of two samples and the difference in value between coefficients of two-sample linear model is asymptotic normal distribution. Furthermore, empirical likelihood (EL) gives efficient estimator for regression coefficients in linear models, and can be as efficient as a parametric approach. The performance of the proposed method is illustrated via numerical simulations.     

论青年研究的学科与路径问题——以英美的青年文化研究为例

基于我国青年研究与英美的文化研究在学科与路径问题上的相似性.而在梳理西方青年文化研究的基础上,借鉴相关的研究实践和理论观点探讨青年研究的学科和路径问题.认为伯明翰学派在英美的青年文化研究领域成就最为卓越,得益于反学科立场和独具特色的研究路径.提出青年研究的核心是再现青年现实.而清醒的问题意识、坚实的学理基础和恰当的研究路径,是研究者进入青年的生活和思想世界而真实、可靠地再现青年现实的必要条件.     

Testing symmetry based on empirical likelihood

In this paper, we propose a general kth correlation coefficient between the density function and distribution function of a continuous variable as a measure of symmetry and asymmetry. We first propose a root-n moment-based estimator of the kth correlation coefficient and present its asymptotic results. Next, we consider statistical inference of the kth correlation coefficient by using the empirical likelihood (EL) method. The EL statistic is shown to be asymptotically a standard chi-squared distribution. Last, we propose a residual-based estimator of the kth correlation coefficient for a parametric regression model to test whether the density function of the true model error is symmetric or not. We present the asymptotic results of the residual-based kth correlation coefficient estimator and also construct its EL-based confidence intervals. Simulation studies are conducted to examine the performance of the proposed estimators, and we also use our proposed estimators to analyze the air quality dataset.     

中国英语学习者写作中的迁移性冗余

冗余是语言和言语交际的固有特征.它不仅与信息相关,而且与语言表达相关.在用英语写作时,中国英语学习者常常将汉语中的语言规则应用到英语作文中,造成冗长和重复性的表达,这种迁移性冗余妨碍了交流的效率.迁移性冗余主要体现在三个层面:句子、段落和语篇,其产生原因与中国人的哲学思想、思维方式及汉语的使用规则和习惯密切相关,了解其表现形式和产生缘由有助于消除这一类的冗余,提高交流的流畅性.     

What Influences the Growth of the Chinese Nonprofit Sector: A Prefecture-Level Study

The nonprofit sector in China has experienced unprecedented growth in its scope and impact over the past four decades. Despite the significant growth, the distribution of nonprofit activities across localities is not well understood. This study combines administrative and census data to examine the size of the Chinese nonprofit sector across 334 prefectures. The study demonstrates a significant variation in nonprofit sector size across prefectures. The study further shows that population heterogeneity, government social spending, and government fragmentation have positive effects on boosting nonprofit sector size in a prefecture. Although diverse service needs affect the growth of the Chinese nonprofit sector, government activities play a more important role in mobilizing nonprofit activities and driving nonprofit sector growth.
