侵权法中的作为义务探究

国外立法例对侵权法中作为义务的规制模式不尽相同,中国台湾地区和大陆地区理论界对作为义务的研究在结合中国司法实践方面略显不足。对于侵权法中作为义务的探究,应当将国外立法例、中国理论界的研究成果与司法实践情况结合起来。中国侵权法中作为义务的设计应当遵循如下思路:无须在一般条款中明确作为义务;合同约定不应成为侵权法中作为义务的来源;不应当规定一般救助义务;作为义务来源应当具有层级性,且该层级性应当以重塑安全保障义务为中心。     

Changes in Family Relationships among Substance Abusing Runaway Adolescents: A Comparison between Family and Individual Therapies

Eligible adolescents (12–17 years old) were recruited from a short‐term crisis shelter for runaway adolescents in a large Midwestern city. Adolescents (N = 179) were randomly assigned to Ecologically‐Based Family Therapy (EBFT, n = 61), the Community Reinforcement Approach (CRA, n = 57), or brief Motivational Enhancement Therapy (MET, n = 61) with the primary focus on substance abuse. A significant increase in perceived family cohesion and a significant reduction in perceived family conflict were found among all treatment conditions from baseline to the 24‐month follow‐up. Adolescents who received EBFT demonstrated more improvement in family cohesion after treatment than those who received CRA or MET, and more reduction in family conflict during treatment than those who received MET.     

Welfare Programme Participation and the Wellbeing of Non-local Rural Migrants in Metropolitan China: A Social Exclusion Perspective

Educational gradient of health in rural China

The aim of this paper is to examine whether and how rural residents’ educational attainment is associated with their self-rated health in China. Taking advantage of the National Exercise Facility Survey that was collected between December 2015 and March 2016, we find that educational attainment has a significant and positive correlation with self-rated health, net of the effects of age, gender, and geographical region. This correlation is mediated by factors such as perceived importance of exercise and healthy lifestyle. Relatively, people’s cognitive knowledge about health-related information and material resource access fail to play a significant mediating role. The findings highlight the non-material and non-cognitive attributes of educational attainment in shaping the gradient of health in the rural setting of China. Interventions that expand formal education to the mass and optimize teaching contents may offer an effective means to balance the health gradient.     

Tail asymptotic of discounted aggregate claims with compound dependence under risky investment

This paper considers the tail asymptotic of discounted aggregate claims with compound dependence under risky investment. The price of risky investment is modeled by a geometric Lévy process, while claims are modeled by a one-sided linear process whose innovations further obeying a so-called upper tail asymptotic independence. When the innovations are heavy tailed, we derive some uniform asymptotic formulas. The results show that the linear dependence has significant impact on the tail asymptotic of discounted aggregate claims but the upper tail asymptotic independence is negligible.

老龄社会背景下我国城市的政治传播研究

在我国的城市已经进入老龄化社会的大背景下,老年人群体在城市的社会稳定和经济发展中的重要性日益体现出来了.要想充分发挥城市老年人在这两个方面的积极作用,不但要确保这一群体思想政治状况的稳定,而且要切实提高他们社会参与的积极性和主动性.无疑,政治传播在这方面应当承担起不可推卸的责任和义务.鉴于城市老年人群体基本上是在社区的范围内生活和活动,就必须做好社区政治传播在社区层面的工作,促使城市老年人以积极健康的心态融入到社会之中,这也有助于提升他们的生活质量.     

偏斜参数对GARCH族模型估计与预测绩效的影响

本文先运用蒙特卡洛模拟考察了偏斜参数对GARCH族模型估计结果的影响并发现,若标准化扰动项偏斜且厚尾,基于对称厚尾分布的极大似然估计量渐近有偏.以上证指数收益为样本,利用SPA检验,实证考察了10种常见的GARCH族结构分别在正态分布、Student-t、GED以及Skew-t分布假设下的波动率预测绩效.结果发现:①Skew-t分布假设下的GARCH族结构能够获得优越的预测绩效;②10种GARCH族结构中,有8种模型在Student-t分布假设下的预测绩效不及正态分布,而GED分布假设下也有4种模型不及正态分布;③样本外观测值的多少以及GARCH-m结构的有无不改变主要结论.
