Guatemala is a nation with a history of severe political and socioeconomic problems. These crises contributed to the growth and durability of insurgent movements, which from 1961 to 1996 were endemic in certain regions of the nation, particularly western Guatemala. This paper examines insurgent activity in the four marketing subsystems described by Smith1 found in western Guatemala: dendritic, primate, top-heavy and interlocking. Peasants are said to be severely disadvantaged in the dendritic marketing systems, disadvantaged in primate markets, and relatively capable of making a decent living in top-heavy and interlocking systems. If this is so, support for system changing revolutionary movements should predictably be highest in dendritic systems, significant in primate systems, and only marginal in top-heavy and interlocking systems. An examination of the political-military situation in western Guatemala from 1976 to 1996 supports this thesis. 相似文献

This article examines US Army psychological operations (PsyOp) as practiced during the waning years of the Cold War in Latin America. Certain themes, especially legitimacy, in-group/out-group, and safety/fear are demonstrated to be recurrent in regional PsyOp campaigns, largely because they seem to activate rich inference systems in the human brain. Yet anthropologists and other scholars of Latin America have paid little attention to military PsyOp. Despite our natural susceptibilities, we can best evaluate propaganda (and other claims to knowledge) by following the advice of Karl Popper: competing theories, including politically loaded ones, should always be explanatory and subject to criticism. 相似文献

This article is a theoretic study of the following problem in verification: Mobile units under control of an agent, whom we call the HIDER, travel on a known transportation network and must at the conclusion of their itinerary report locations at fixed time intervals to a monitoring authority, whom we call the SEEKER. The purpose of this reporting requirement is to verify that illegal units do not infiltrate the network from sources under the control of the HIDER. We assume that the SEEKER has an independent intelligence-gathering capability which gives sightings of both legal and illegal units. The purpose of this article is to quantify the advantage of frequent over infrequent reporting. © 1992 John Wiley & Sons, Inc. 相似文献

A system is subject to shocks that arrive according to a nonhomogeneous Poisson process. As shocks occur a system has two types of failures. Type 1 failure (minor failure) is removed by a minimal repair, whereas type 2 failure (catastrophic failure) is removed by replacement. The probability of a type 2 failure is permitted to depend on the number of shocks since the last replacement. A system is replaced at the times of type 2 failure or at the nth type 1 failure, whichever comes first. The optimal policy is to select n* to minimize the expected cost per unit time for an infinite time span. A numerical example is given to illustrate the method. © 1996 John Wiley & Sons, Inc. 相似文献

Military reading lists, intended to promote professional reading and in turn enhance education and develop critical thinking skills and sound judgement, recommend key texts to military personnel. This is a noble intent but the lists themselves, while generally good, are not flawless. Critiques of military reading lists often focus on what sources they are missing. This article offers its own critique but from a different perspective. It does so by analysing why some sources, which have become outdated, are based on faulty or incomplete research, have been thoroughly disproven, or some combination of the above, nevertheless linger on military reading lists. It then offers a short list of such sources, which it recommends be either removed from existing reading lists or accompanied by other sources that place the original source in appropriate historical context. Where applicable, it also recommends alternative sources that provide insights into the same subject matter. In so doing, this article is intended generate debate and to assist militaries to achieve a better balance between evaluation, induction and retention of valid knowledge on one hand, and rejection of outdated or flawed knowledge on the other. 相似文献

A potentially productive triangular arrangement among Russia, Ukraine, and the United States emerged in 1994 from efforts to constrain nuclear weapons diffusion. By 2001, this promising initiative was nearly moribund, owing to the inability or unwillingness of the parties to fulfill the commitments of subsequent agreements. The domestic and external causes of this failure are many and clear. Yet the advantages to each of reengaging in a trilateral relationship are also plain. This means fulfilling their unfinished agenda by learning from past mistakes, adopting realistic premises and goals, and pursuing ‘bottom up’ as well as ‘top down’ strategies. 相似文献

Did the Panamanian Defense Forces conduct infiltration operations at the Arraijan Tank Farm in 1988?

This article reviews the circumstances surrounding a relatively obscure and almost forgotten US Marine Corps and Army security enhancement operation undertaken in Panama that commenced in early April of 1988. Marines were sent to Panama to protect oil and ammunition storage facilities from potential saboteurs. By April 1989 they had reported sighting armed, uniformed intruders on at least 43 occasions and receiving gunfire or discharging their own weapons during 16 incidents. Yet despite the repeated barrages of small arms fire over the course of a year, they failed to recover enemy ammunition, bodies or body parts and their own equipment and positions displayed no signs of suffering from hostile fire. This article analyzes the events from the point of view of a veteran of the operation and highlights the role that psychological operations may have played in generating the situation. 相似文献

U.S. nuclear export policy has undergone major transformations since 1945, and the most recent change, as expressed in the July 18, 2005, India-U.S. Joint Statement, represents an especially significant shift in policy. The document reverses more than a quarter century of U.S. declaratory policy, suggesting that the current U.S. administration regards nuclear proliferation to be both inevitable and not necessarily a bad thing. This article investigates this policy shift, looking at the history of U.S. nuclear export policy and the potential ramifications of the new policy on the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). The author also touches on the potential effects of the Joint Statement on Indian-Pakistani relations. Finally, it is suggested that it is not too late for India and the United States to change the new policy with more consideration for the NPT and the Nuclear Suppliers Group Initiative. 相似文献
