Ungoverned space? Examining the FARC's interactions with local populations in Northern Ecuador

The Ecuadorian state has long been absent from the regions along its northern border with Colombia. I argue that this lack of state presence has allowed non-state armed groups and criminal organizations space to not only operate from these areas, but also, to challenge and change the relationship between local populations and the Ecuadorian state. After reviewing theoretical approaches to concepts of changing security paradigms and ungoverned space, the article details the conditions that have allowed armed groups, specifically the FARC, to take advantage of the lack of state presence along Ecuador's northern border.     

The essence of war: French armies and small war in the Low Countries (1672–1697)

In the late seventeenth century during the Dutch War (1672–1678) and the Nine Years War (1688–1697), French armies relied on small war for the accomplishment of essential tasks and as part of an overall strategy of exhausting their opponents in the Low Countries. The purposes of small war included the imposition of contributions on enemy populations, the destruction of the enemy base of operations, blockades of fortresses, and the general support of campaign armies. The expression ‘small war’ in the French language appeared with growing frequency in the 1690s. Small war can be viewed as both a cause and consequence of the characteristics of these wars. The limited policy goals of Louis XIV the king of France required a strategy that minimised risk and accomplished the goal of reducing if not eliminating the Spanish presence in the Low Countries that bordered the north of France. As French armies increased in size during this period, the demand for specialists at small increased in order to provide security and ensure supply. Small war in the late seventeenth century was thus not ideologically motivated insurgency, but in the minds of French commanders an essential component of strategy and the nature of war.     

Initiating insurgencies abroad: French plans to ‘chouannise’ Britain and Ireland, 1793–1798

Secret French plans to launch guerrilla-style raids on the British Isles devised in the spring of 1796 were referred to as ‘chouanneries’. The name and concept behind these small-war operations were modelled on the irregular tactics used by the Chouan rebels in the Vendée, which the French state army had brutally quashed, but some wished to transfer into their institutional practice. Part of France's ongoing military strategy in the war against Britain, which included fomenting insurrection in Ireland, these irregular operations were to be manned partially by pardoned deserters and released convicts and prisoners of war. Of these, only Tate's brief invasion of Wales in 1797 was realised, but the surviving plans provide insightful historical lessons into an Anglophobic mindset shared by a small network of practitioners and policy deciders on the effectiveness of such shock and awe tactics. Largely motivated by the desire to take revenge for Britain's support of counter-revolutionaries in the Vendée, these plans could more aptly be referred to as counter-‘chouanneries’.     

对成像雷达的脉冲分段排序转发干扰

多假目标图像欺骗是目前宽带雷达干扰的难点。针对宽带雷达中常用的线性调频(Linear Frequency Modulated,LFM)信号,提出一种脉冲分段排序转发干扰方法。结合散射波信号模型,推导了合成干扰信号二维成像输出形式,讨论了假目标图像个数、分辨率与分段数以及转发次序之间的关系,并进行了仿真实验。结果表明该干扰方法可较便捷地产生多个沿距离向分布的假目标图像。结果对于成像雷达图像欺骗干扰具有理论指导意义。     

Upstream engagement and downstream entanglements: The assumptions,opportunities, and threats of partnering

This article addresses Western recruitment and management of personnel from non-Western countries in armed forces as part of a strategy of state stabilisation, examining its risks and benefits. ‘SFA’ (Security Forces Assistance) to indigenous forces has long been practised by the West and seems to have returned in recent years in a new form with the creation of armies in Iraq and Afghanistan. However, while providing cheap, proxy substitutes for the West and offering opportunities for state-building, the policy creates its own problems and can have significant, negative consequences.     

Urban violence and the militarisation of security: Brazilian ‘peacekeeping’ in Rio de Janeiro and Port-au-Prince

Despite problems of violence domestically, Brazil has played a key leadership role as part of MINUSTAH peacekeeping operations in Haiti since 2004. This article addresses how Brazil's international military engagement is shaping domestic approaches to urban security, and what may be the implications of the use of military strategies, operations, and norms to address issues of public security in Brazilian cities. It is argued that current approaches toward urban security employing military-trained peacekeepers actually represent a continuation of old paradigms, yet these recent militarised approaches are likely evolving into newer and potentially more accountable forms by constraining indiscriminate use of force and establishing a positive state presence in marginal urban areas. As such, the article connects long-established issues of dealing with urban violence in Latin America with ongoing debates in the United States and beyond about post-counterinsurgency approaches to increasingly urban conflict settings. It reflects on potential lessons to be learned from the Latin American perspective, while showing also how these have changed over the last decade. The article concludes that despite the potential utility of force in some urban conflict settings, this approach could entail a normative shift towards legitimising forceful containment of violence, and hinder democratic consolidation in Brazil.     

A branch‐and‐price approach for the stochastic generalized assignment problem

In this article, we address a stochastic generalized assignment machine scheduling problem in which the processing times of jobs are assumed to be random variables. We develop a branch‐and‐price (B&P) approach for solving this problem wherein the pricing problem is separable with respect to each machine, and has the structure of a multidimensional knapsack problem. In addition, we explore two other extensions of this method—one that utilizes a dual‐stabilization technique and another that incorporates an advanced‐start procedure to obtain an initial feasible solution. We compare the performance of these methods with that of the branch‐and‐cut (B&C) method within CPLEX. Our results show that all B&P‐based approaches perform better than the B&C method, with the best performance obtained for the B&P procedure that includes both the extensions aforementioned. We also utilize a Monte Carlo method within the B&P scheme, which affords the use of a small subset of scenarios at a time to estimate the “true” optimal objective function value. Our experimental investigation reveals that this approach readily yields solutions lying within 5% of optimality, while providing more than a 10‐fold savings in CPU times in comparison with the best of the other proposed B&P procedures. © 2014 Wiley Periodicals, Inc.

Japan as a Seapower: Strategy,Doctrine, and Capabilities under Three Defence Reviews, 1995–2010

Abstract

This article draws upon previously unavailable document materials to question views pointing to a degree of stagnation in Japanese maritime thinking. It similarly reviews claims about trends to compensate the decline of national military power with the build-up of projection capabilities. The article’s main argument is that Japanese seapower is not declining. The Japanese Navy is evolving to combine enhanced capabilities to retain sea control in the Sea of Japan and the East China Sea with extended operational reach and flexibility, including an expeditionary component to meet alliance and diplomatic commitments in East Asia and beyond its confines.     

The evolution of Hezbollah's strategy and military performance, 1982–2006

This article fills a gap in the research on Hezbollah by evaluating their military performance from their formation in 1982 and up till the 2006 Israel–Hezbollah war. This study tests the theses that Hezbollah had developed a very strong tactical proficiency in the late 1990s and that there are more similarities in their strategy and tactics during the 2006 war and the 1982–2000 insurgency in Southern Lebanon than previously assumed. Another central theme of this article is how Hezbollah has been constantly adapting and evolving for the duration of its existence.
