二十世纪美国反恐情报应用模式初探

美国作为较早受到恐怖主义威胁的西方发达国家，自20世纪70年代逐渐发展起了一套完善的执法体系，并积累了成熟的执法经验，特别是信息化时代背景下，美国执法部门的反恐斗争渗透着强烈而鲜明的信息情报色彩，是“情报导侦”理念和模式的现实体现，为我国执法与行动部门提供了一定的经验。其中的“威胁评估”综合情报分析模式是美国反恐情报工作的典型代表，对于预防恐怖主义犯罪起着特殊的作用。     

How long until midnight? Intelligence-policy relations and the United States response to the Israeli nuclear program, 1959–1985

Why did the United States fail to stop Israeli acquisition of nuclear weapons? Existing research argues that patrons such as the U.S. should have an easy time halting proliferation by militarily and economically vulnerable clients. Nevertheless, Israel acquired nuclear weapons with relatively little American opposition. Utilizing extensive primary source research, we argue that problematic intelligence-policy relations hindered U.S. efforts to arrest Israeli proliferation as (1) policymakers often gave mixed guidance to the intelligence community, resulting in (2) limited information on Israeli efforts that reinforced policy ambiguity. The results carry implications for understanding the dynamics of nuclear proliferation and intelligence-policy relations.     

On the contribution of defense innovation to China’s economic growth

As the most knowledge-intensive industrial sectors, China’s defense industries are developing very fast. The present paper will explore the contribution of China’s defense innovation to its economic growth. Cobb–Douglas production function, integrating defense and non-defense stock in knowledge, is applied during the course. In addition, an input–output analysis of defense equipment procurement was done. Positive effect of China’s defense innovation on economic growth has been revealed by comparing the results from the two methods. And some suggestions are made to strengthen the effect.     

Capacity investment decisions under risk aversion

This article studies the optimal capacity investment problem for a risk‐averse decision maker. The capacity can be either purchased or salvaged, whereas both involve a fixed cost and a proportional cost/revenue. We incorporate risk preference and use a consumption model to capture the decision maker's risk sensitivity in a multiperiod capacity investment model. We show that, in each period, capacity and consumption decisions can be separately determined. In addition, we characterize the structure of the optimal capacity strategy. When the parameters are stationary, we present certain conditions under which the optimal capacity strategy could be easily characterized by a static two‐sided (s, S) policy, whereby, the capacity is determined only at the beginning of period one, and held constant during the entire planning horizon. It is purchased up to B when the initial capacity is below b, salvaged down to Σ when it is above σ, and remains constant otherwise. Numerical tests are presented to investigate the impact of demand volatility on the optimal capacity strategy. © 2016 Wiley Periodicals, Inc. Naval Research Logistics 63: 218–235, 2016     

The financial performance of aircraft manufacturers during world war II: the vicissitudes of war

Controversy has long surrounded the role and profitability of US defense contractors. From a financial perspective the question becomes whether defense contractors earn greater profits and investor returns than other companies during military conflicts. We explore this question by examining the accounting profitability and investor returns of US aircraft manufacturers before, during, and after World War II and compare them to a sample of non-defense firms. We also examine the reactions of aircraft stock prices to important political and military events of the time. We find that (1) aircraft stocks exhibited positive abnormal returns around events associated with defense buildups and outbreaks of hostile action and negative returns around events signaling an end to hostilities, (2) the company’s accounting returns improved during the war but these higher accounting returns did not translate into higher stock returns for the shareholders, and (3) investors could have earned higher stock returns had they switched out of aircraft stocks after Pearl Harbor and reinvested the proceeds in the overall market.

An Imperfect Jewel: Military Theory and the Military Profession

This article explores a perennial theme in the literature of strategic studies: the relationship between military theory and the military profession. It begins with a conceptual analysis of this relationship. It then investigates what military theorists themselves have had to say about the utility of their craft. It concludes by assessing the actual influence of military theory on selected individuals and institutions. The individuals are George S. Patton, Jr., and Ulysses S. Grant. The institutions are the United States Army and the United States Air Force in the late twentieth century. The fundamental finding is suggested in the title: military theory can indeed be quite useful in the maturation of military commanders and in the development of martial institutions, but it is not always necessary and by no means perfect. It should thus be studied assiduously but used with caution.
