Uniform asymptotics for ruin probability of a two-dimensional dependent renewal risk model

ABSTRACT

In this paper we consider the tail behavior of a two-dimensional dependent renewal risk model with two dependent classes of insurance business, in which the claim sizes are governed by a common renewal counting process, and their inter-arrival times are dependent, identically distributed. For the case that the claim size distribution belongs to the intersection of long-tailed distribution class and dominant variation class, we obtain an asymptotic formula, which holds uniformly for all time in an infinite interval. Moreover, we point out that the formula still holds uniformly for all time in an infinite interval for widely dependent random variables (r.v.s) under some conditions.     

读懂《多余的话》的一些想法

瞿秋白在《多余的话》中通过自我否定、自我丑化,自制了一个负面形象的瞿秋白,目的是要使杨之华厌恶自己,忘却自己.他不愿因自己的死给亲人留下巨大的伤痛.瞿秋白的这一良苦用心也给《多余的话》带来不应有的负面效应.《多余的话》中有真话、反话,也有不少夸大真实的话,读懂《多余的话》,不能望文生义.     

物理化学设计型实验的测量知识准备

物理化学是一门与其他学科交叉渗透的综合性强大学科.从训练学生综合分析解决实际问题的能力、培养创新意识等方面来看,物理化学实验很具有代表性.因此物理化学实验教学改革的方案也比较多,很多很好的设计型或者叫科研型方案被提出.然而开设该设计型实验课之前,学生需要对于传感器、测量、计算机等方面知识做些准备,文章就此提出一些想法和建议.

生态行政学:理论源流、分化及其困顿

由于生态环境的恶化,政府和公民迫切需要行动起来,以应对日益严峻的生存危机.在反思工业文明的过程中,具有后现代情境的生态主义为生态行政理论提供了实践理性的基础.生态政治的核心价值和现实偏向以及行政生态理论的历史发展,均催化着生态行政理论的萌芽.由于概念认定和价值趋向的差异,以及范式转换和治理领域悖论的存在,生态行政研究亦呈现出分化、多元化与发展的困顿.生态行政理论应在整体性与共生性的原则下着力提升治理系统的开放性和必要的多样性,以应对环境领域日益严峻的复杂性与不确定性.     

Statistical evaluation of individual bioequivalence

Drug switchability requires the evidence of individual bioequivalence which -refers to the comparison of the closeness between the two distributions of the pharmacokinetic (PK) responses from the same subject obtained under the repeated administrations of the test and reference formulations. Advantages and drawbacks of the current statistical procedures for assessment of individual bioequivalence are discussed with emphasis on the aggregate-based criteria, An intersection-union test based on disaggregate criteria is proposed for the evaluation of individual bioequivalence. In addition, a modified aggregated criterion is suggested to overcome the drawbacks suffered by aggregate criteria. The relationships among different criteria are examined, and the performance of the procedures will be compared. A numerical example is given to illustrate the proposed procedures.     

Psychometric and Demographic Predictors of the Perceived Risk of Terrorist Threats and the Willingness to Pay for Terrorism Risk Management Programs

A 2009 national telephone survey of 924 U.S. adults assessed perceptions of terrorism and homeland security issues. Respondents rated severity of effects, level of understanding, number affected, and likelihood of four terrorist threats: poisoned water supply; explosion of a small nuclear device in a major U.S. city; an airplane attack similar to 9/11; and explosion of a bomb in a building, train, subway, or highway. Respondents rated perceived risk and willingness to pay (WTP) for dealing with each threat. Demographic, attitudinal, and party affiliation data were collected. Respondents rated bomb as highest in perceived risk but gave the highest WTP ratings to nuclear device. For both perceived risk and WTP, psychometric variables were far stronger predictors than were demographic ones. OLS regression analyses using both types of variables to predict perceived risk found only two significant demographic predictors for any threat—Democrat (a negative predictor for bomb) and white male (a significant positive predictor for airline attack). In contrast, among psychometric variables, severity, number affected, and likelihood were predictors of all four threats and level of understanding was a predictor for one. For WTP, education was a negative predictor for three threats; no other demographic variables were significant predictors for any threat. Among psychometric variables, perceived risk and number affected were positive predictors of WTP for all four threats; severity and likelihood were predictors for three; level of understanding was a significant predictor for two.     

论我国刑事审判监督“诉监分置模式”之构建——以“角色理论”为分析工具

由公诉人行使刑事审判监督职能的合理性以及实践中存在的"监督不到位"的问题,是我国刑事诉讼制度中备受诟病和争议的焦点。本文运用法社会学的研究路径和角色理论解读刑事审判监督对我国现代刑事诉讼制度构建的影响,提出了有利于增强监督实效的"诉监分置"模式的理论构想。
