国家安全中枢的构筑——对十八届三中全会决定“设立国家安全委员会”的解读

国家安全委员会具有“内外兼备”的基本职能,即：将维护国家安全与创新社会治理、创新有效预防和化解社会矛盾体制、健全公共安全体系等内政事务并列并举,在维护国内安全稳定方面也肩负重任。它较之现今的“国安领导小组”更为广泛和重要,是一个应对有别于国家日常工作之外的应急的危机管理机构,是应对可能的、突发的、潜在的对国家安全、利益构成威胁的前瞻性机构。     

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.     

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.     

Assessing the value of demand sharing in supply chains

We consider the problem of assessing the value of demand sharing in a multistage supply chain in which the retailer observes stationary autoregressive moving average demand with Gaussian white noise (shocks). Similar to previous research, we assume each supply chain player constructs its best linear forecast of the leadtime demand and uses it to determine the order quantity via a periodic review myopic order‐up‐to policy. We demonstrate how a typical supply chain player can determine the extent of its available information in the presence of demand sharing by studying the properties of the moving average polynomials of adjacent supply chain players. The retailer's demand is driven by the random shocks appearing in the autoregressive moving average representation for its demand. Under the assumptions we will make in this article, to the retailer, knowing the shock information is equivalent to knowing the demand process (assuming that the model parameters are also known). Thus (in the event of sharing) the retailer's demand sequence and shock sequence would contain the same information to the retailer's supplier. We will show that, once we consider the dynamics of demand propagation further up the chain, it may be that a player's demand and shock sequences will contain different levels of information for an upstream player. Hence, we study how a player can determine its available information under demand sharing, and use this information to forecast leadtime demand. We characterize the value of demand sharing for a typical supply chain player. Furthermore, we show conditions under which (i) it is equivalent to no sharing, (ii) it is equivalent to full information shock sharing, and (iii) it is intermediate in value to the two previously described arrangements. Although it follows from existing literature that demand sharing is equivalent to full information shock sharing between a retailer and supplier, we demonstrate and characterize when this result does not generalize to upstream supply chain players. We then show that demand propagates through a supply chain where any player may share nothing, its demand, or its full information shocks (FIS) with an adjacent upstream player as quasi‐ARMA in—quasi‐ARMA out. We also provide a convenient form for the propagation of demand in a supply chain that will lend itself to future research applications. © 2014 Wiley Periodicals, Inc.

The prospects of combined action: Lessons from Vietnam

Military commanders, policymakers, and analysts have recently embraced the concept of combined action as a powerful tool to improve the effectiveness of Afghan security forces in the fight against the Taliban. In doing so, they explicitly draw inspiration from the Combined Action Program employed by US Marines during the Vietnam War. This program is widely considered to have greatly improved the effectiveness of South Vietnamese government forces and contributed to increased population security in its area of operations and is considered a model worthy of emulation. This study finds that the success of the Vietnam-era Combined Action Program was more qualified than contemporary proponents argue. It argues that successes were tempered, and conditioned, by the choice of junior commanders, the level of operational control enjoyed by the US Marines, and the way the local forces were recruited and deployed. These conditions offer valuable lessons for those seeking to employ combined action not only in present-day Afghanistan, but also in future counterinsurgency campaigns.     

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.     

Political transition to democracy

This paper argues that the crisis of electoral democracy in Zimbabwe and Cote d'Ivoire is a result of underlying structural and institutional deficiencies within national and regional multinational institutions. It assesses the extent to which they have been ‘enablers’ or ‘spoilers’ of electoral-based transitions to democracy. Yet it avoids generalisations of the security sector's involvement in political transitions. In terms of structure, the paper is divided into four sections. Section one will briefly discuss the theoretical perspectives of the election-democracy trajectory. It argues that although elections are a major variable for democracy, unless the ‘ecology of elections’ is conducive, elections may not be an instrument of transition to democracy. The second section analyses the militarisation of politics and the role of the security sector in aiding or stalling democratisation. Section three will assess the role of regional organisations such as the Southern African Development Community, Economic Community of West African States and the African Union in electoral-based political transitions in Africa. Lastly, the paper will discuss how the security sector and multinational African institutions can aid political transitions to democracy in troubled African countries.     

Neglected but affected: voices from the oil-producing regions of Ghana and Uganda

The ‘resource curse’ is the paradoxical theory frequently used to explain how a seemingly desirable asset, such as oil, can actually pervert an economy, erode governance, perpetuate conflict, and ruin local communities to the extent that it becomes a curse. New oil discoveries in western Ghana and western Uganda have raised concerns for the democratic prospects and future stability of these countries and their surrounding regions. Based on field interviews in these oil-producing regions, this report summarises how local communities have been affected thus far and their concerns for the future. The authors assess the extent to which each country is vulnerable to oil-induced instability, and identify groups or communities that would be most likely to perpetuate it. Lastly, it provides some assessment of the future trajectory of each country.     

The elephant in the room

When United States (US) President Barack Obama announced in 2013 that he would host the first United States-Africa leaders' summit the next year, he was greeted with considerable scepticism. Many critics thought he was just playing catch-up with other countries and organisations which had been holding Africa summits for years, especially China. But, whatever the motives, the event itself proved to be a substantial success, probably re-setting US relations with Africa for many years to come.
