论经济分析方法在军事法中的应用

伴随着经济学的发展,经济分析方法于上世纪被引入法学领域,形成法经济学。经过半个世纪的努力,经济分析方法已经出现在众多部门法学研究中。军事法作为一门独立的部门法学并不排斥经济分析方法,用经济分析方法研究军事法具有重要意义。     

Determination of burn‐in parameters and residual life for highly reliable products

Today, many products are designed and manufactured to function for a long period of time before they fail. Determining product reliability is a great challenge to manufacturers of highly reliable products with only a relatively short period of time available for internal life testing. In particular, it may be difficult to determine optimal burn‐in parameters and characterize the residual life distribution. A promising alternative is to use data on a quality characteristic (QC) whose degradation over time can be related to product failure. Typically, product failure corresponds to the first passage time of the degradation path beyond a critical value. If degradation paths can be modeled properly, one can predict failure time and determine the life distribution without actually observing failures. In this paper, we first use a Wiener process to describe the continuous degradation path of the quality characteristic of the product. A Wiener process allows nonconstant variance and nonzero correlation among data collected at different time points. We propose a decision rule for classifying a unit as normal or weak, and give an economic model for determining the optimal termination time and other parameters of a burn‐in test. Next, we propose a method for assessing the product's lifetime distribution of the passed units. The proposed methodologies are all based only on the product's initial observed degradation data. Finally, an example of an electronic product, namely contact image scanner (CIS), is used to illustrate the proposed procedure. © 2002 Wiley Periodicals, Inc. Naval Research Logistics, 2003

Epidemics,national security,and US immigration policy

What are relationships between epidemics, national security, and US immigration policy? This question is important because it sheds light on transnational or nontraditional security areas, American immigration policy, and a pressing issue for US leaders who have recently faced epidemics such as the West Africa Ebola outbreak that began in 2013. This article answers it and lays ground in the area by reviewing epidemics in world history, using International Relations and Security Studies works to specify dangers of contagions for states, and identifying three general immigration measures that American leaders have utilized from the seventeenth century to the present day to protect against contagions, which are (1) policies restricting entrance of foreigners thought to carry specified diseases, (2) the isolation or quarantining of immigrants with contagious disease, and (3) delegating the President with authority to stop immigration in the event of an epidemic abroad. This study has implications for research and contemporary US immigration policy.     

A Re-assessment of the Japanese Armaments Production During World War II*

Abstract

This paper examines the nexus between the Japanese strategy and economic–industrial mobilization during the period 1937–1945. From 1937 to December 1941, the country was engaged in a land war of attrition in China. This war requested an immense amount of resources and was associated with armaments procurement strategy with emphasis in the army. However, the Japanese strategic vision assumed that the state was strong enough to engage in one land war against China and in a naval war in the Pacific simultaneously. The basis of Japanese strategy was a utopia. Making things worse, the naval war in the Pacific was conducted against the most industrialized powers in the world [the US and the British Empire (Britain, Australia, India, etc.)]. Finally, the internal Japanese industrial mobilization was associated with immense errors in armaments production (absence of economies of scale and scope, limited raw materials, etc.). Under these circumstances, the defeat was an expected outcome.
