军人伤亡保险存在的问题探析

军人伤亡保险作为军人保险制度的重要组成部分,其经济补偿功能已经被广大官兵逐渐认可。但作为分散军人职业风险的特定机制,其作用并未被充分开发出来,主要表现在较低的补偿水平等方面。因此,应充分借鉴国内外的相关经验,扬长避短,以充分发挥军人伤亡保险的作用。     

随军配偶未就业期间社会保险问题分析

军人配偶随军未就业期间社会保险的建立解决了军人配偶在随军未就业期间的基本生活补贴和养老、医疗保险问题,在一定程度上保障了随军配偶的利益。但在执行过程中也出现一些诸如险种较少,保障范围较窄,保障程度较低等问题。在分析存在问题的基础上,提出一些完善社会保险的建议。     

Bivariate models from univariate life distributions: A characterization cum modeling approach

Bivariate life distribution models are of importance for studying interdependent components. We present a generic approach by introducing a new concept of characterized model in stead of a characterized distribution. It strikes a balance between characterization and modeling approaches to eliminate their individual limitations and incorporate their respective strengths. The proposed model, being a characterized one, admits many important properties irrespective of the choice of marginal distributions. The retention of univariate IFR, DFR, IFRA, DFRA, NBU, and NWU class properties in the bivariate setup has been ensured along with some results on series combinations and convolution. No other models, available in the literature, can ensure simultaneous retention of these fundamental and extremely important class properties. © 2004 Wiley Periodicals, Inc.

一种基于混合模拟的计算组合电路中软错误率的方法与工具

随着工艺尺寸的不断缩小,组合电路引起的SER(Soft Error Rates)越来越严重.针对使用HSPICE计算组合电路软错误率速度较慢以及使用传统的组合电路软错误率分析工具在对待重汇聚时计算精度不高的问题,本文提出了一种混合模拟的方法,并基于该方法实现了组合电路软错误率分析工具.该混合模拟方法使用HSPICE模拟发生重汇聚的逻辑门;使用快速的脉冲传播算法模拟其他逻辑门.模拟结果表明,该方法可以在速度和精度上达到很好的折中.通过与国际上常用的组合电路软错误率分析工具进行比较发现,在重汇聚发生较多的电路中,该混合模拟方法更能真实地反应组合逻辑中的软错误率.

Health Insurance,Health Conditions,and Veteran Health Care Utilization

Abstract

The utilization of health care services by veterans has received much attention in recent years. However, the impact of the large array of factors affecting the veterans’ demand for health care services remains understudied. These factors include individual socio-demographic and economic characteristics, the availability of various sources of health insurance, and the prevalence of medical conditions. We use public data to analyze how veterans’ utilization of health care services varies with these factors. We also analyze how the reliance on VA services varies when alternative sources of health insurance are available to veterans. Based on the estimated relationships, we use a micro-simulation model to forecast future health care utilization, both inside and outside of VA.     

Many‐server loss models with non‐poisson time‐varying arrivals

This article proposes an approximation for the blocking probability in a many‐server loss model with a non‐Poisson time‐varying arrival process and flexible staffing (number of servers) and shows that it can be used to set staffing levels to stabilize the time‐varying blocking probability at a target level. Because the blocking probabilities necessarily change dramatically after each staffing change, we randomize the time of each staffing change about the planned time. We apply simulation to show that (i) the blocking probabilities cannot be stabilized without some form of randomization, (ii) the new staffing algorithm with randomiation can stabilize blocking probabilities at target levels and (iii) the required staffing can be quite different when the Poisson assumption is dropped. © 2017 Wiley Periodicals, Inc.

The real exchange rate Enigma: A safe haven solution from the cold war era

In this paper I shift the focus of real exchange rate analysis from conventional macroeconomic variables, which have failed to explain changes in floating real dollar exchange rates, to military security variables, which show an uncanny ability to explain the pattern of floating real exchange rate changes among NATO‐area floating currencies from early 1973 through the failed Soviet coup of August, 1991.
