A nuclear-armed North Korea without ICBMs: the best achievable objective

This article analyzes the North Korean nuclear crisis from a balance-of-power perspective. It is in the long-term interests of international peace for a secure and independent North Korea to serve as a buffer between US and Chinese ground forces. However, the conventional military advantage of the South Korean-American alliance over North Korea has grown drastically since the end of the Cold War, threatening North Korea’s survival. Since North Korea lacks any reliable ally, nuclear weapons represent its most cost-effective way to restore a balance of power and thus secure itself. Accepting security guarantees in exchange for its nuclear arsenal is rhetorically appealing but not a viable approach. North Korea’s development of intercontinental ballistic missiles (ICBMs), however, has overcompensated for the post-Cold War imbalance, inviting talk in Washington of waging a preventive war. Persuading North Korea to give up its ICBM capability, not its nuclear arsenal, should therefore be the primary objective of US diplomacy.     

A bivariate optimal replacement policy for a cold standby repairable system with repair priority

In this article, an optimal replacement policy for a cold standby repairable system consisting of two dissimilar components with repair priority is studied. Assume that both Components 1 and 2, after repair, are not as good as new, and the main component (Component 1) has repair priority. Both the sequence of working times and that of the components'repair times are generated by geometric processes. We consider a bivariate replacement policy (T,N) in which the system is replaced when either cumulative working time of Component 1 reaches T, or the number of failures of Component 1 reaches N, whichever occurs first. The problem is to determine the optimal replacement policy (T,N)* such that the long run average loss per unit time (or simply the average loss rate) of the system is minimized. An explicit expression of this rate is derived, and then optimal policy (T,N)* can be numerically determined through a two‐dimensional‐search procedure. A numerical example is given to illustrate the model's applicability and procedure, and to illustrate some properties of the optimal solution. We also show that if replacements are made solely on the basis of the number of failures N, or solely on the basis of the cumulative working time T, the former class of policies performs better than the latter, albeit only under some mild conditions. © 2010 Wiley Periodicals, Inc.

内隐自尊、外显自尊及其交互作用对应对方式的影响研究

为了探讨内隐自尊、外显自尊及其交互作用对应对方式的影响,我们采用实验设计方法对某大学60名学生进行研究,选用自尊量表（SES）、应对方式问卷（CSQ）和内隐测验程序（IAT）施测。结果显示：一是内隐自尊、外显自尊存在低相关;二是外显自尊在积极、消极两种应对方式上主效应显著;三是不同外显自尊水平下,内隐自尊对积极应对方式有不同的影响。即高外显自尊水平下,高内隐自尊者比低内隐自尊者应用更多的积极应对方式;低外显自尊水平下,内隐自尊水平不影响积极应对方式的应用。由此可见,自尊类型影响个体应对方式,要培养个体安全的高自尊以促使个体在压力面前更多使用积极应对方式。
