How not to pay for the war

As a result of allied subsidy and the influence of sunk costs, the marginal cost of the Gulf War to the US was reduced to negligible size. This result is at variance with the Olson‐Zeckhauser thesis that in an alliance “the small exploit the large.” A game theoretic alternative explanation suggests that the relation between allies resembles the game of Chicken, successfully played by the US. The ability to shift the marginal costs of war in the short term raises questions about the possible underestimation of long term effects.     

Turkey-Africa alliance: Evolving patterns in security relations

ABSTRACT

Turkey has maintained its strategic relations with Africa at the highest level under recent AK Party governments in the field not only of low politics but also of high politics. For example, it opened its largest overseas military base in Somalia in 2017 and signed military, defense and security pacts with more than 25 African countries. This article traces the deep historical and cultural relations with Africa behind its newly evolving foreign policy identity, arguing that its booming economic power has been a significant driving force in shaping a new security strategy. It examines what the growing security involvement means for both Turkey and Africa in order to contribute to the relevant literature through a holistic approach from both theoretical and conceptual perspectives.

CREATING SUNS ON EARTH

Concerns about climate change and energy security have prompted some countries to revive dormant nuclear fission power programs to meet growing energy demands and reduce carbon dioxide emissions. However, this so-called nuclear renaissance based on fission would have major drawbacks in the areas of safety, security, and nonproliferation. Nuclear fusion, however, is portrayed by its proponents as mitigating these drawbacks, and scientists continue to pursue fusion's promise with two large-scale projects: the International Thermonuclear Experimental Reactor (ITER), and the Laser Inertial Fusion Engine (LIFE) reactor. Although supporters often hail fusion as proliferation resistant, the technology could be used to create weapons-usable fissile material. This article explains how fissile material could be created in ITER or LIFE and analyzes other nonproliferation implications of fusion; the authors discuss the various challenges faced by ITER and LIFE.     

Greek response to the Cyprus invasion

The contemporary history of three countries was marked on July 1974 when the Greek colonels overthrew the legitimate government of Cyprus, Turkey invaded the island to preserve her interests and Greece returned to democracy, but withdrew from NATO. The apathy of her allies was a bitter experience for Greece, considering that the government in Athens was struggling to cope with the consequences of the invasion and Turkey's aggression, as well as with the diplomatic isolation caused by the seven-year dictatorial rule. This paper examines the response of the Greek government and makes particular reference to Karamanlis's archives and Greek parliamentary proceedings. The purpose of the present study is to explore whether Greece was genuinely committed to the settlement of the Cyprus issue and failed due to lack of support or simply ignored the appeals of the Cypriot people and pursued more vital foreign policy objectives, thus contributing to the partition of the island.     

The strategic utility of New Zealand Special Forces

In 1955, the New Zealand government authorised the creation of a Special Forces unit to operate with British forces in Malaya to counter a communist-inspired guerrilla insurgency. Drawing upon the operational experiences of the New Zealand SAS largely taken from the Cold War period, and underpinned by Colin Gray's Special Forces essentials of ‘economy of force’ and ‘expansion of choice’, this article will show how New Zealand's SAS is now accepted not only as a respected and relevant part of the nation's military capability, but also empowers its political decision-makers with the confidence to take on significant, and at times difficult, strategic foreign-policy choices.     

Cognitivism,prospect theory,and foreign policy change: a comparative analysis of the politics of counterinsurgency in Malaya and Afghanistan

This article investigates the cognitive limitations on policy change in counterinsurgency (COIN) efforts by examining why American decision-makers failed to revise their government strategy substantially while fighting the insurgency in Afghanistan in 2003–2014 and why their British counterparts were more successful in adjusting their policies in the Malayan insurgency in 1948–1954. Unlike most of the COIN literature that concentrates on military strategy and tactics, the analysis of government policy-making in Malaya holds some important political lessons for American leaders today despite differences between the insurgencies in Afghanistan and British Malaya. As a response to the criticism of COIN studies in general that they lack theoretical guidance, this article utilizes an integrated cognitivist-prospect theory framework. It is argued that some of the COIN literature mistakenly suggests that a more difficult strategic situation was primarily responsible for American failure in Afghanistan. Instead, American decision-makers faced a more difficult task cognitively than their British counterparts, as policy change in Afghanistan would have required greater ideational change. American principals were much more attached to their beliefs emotionally, had no alternative problem representation, and had to shift between frames in order to engineer a response that was more in line with events on the ground in Afghanistan. Regarding prospect theory, findings indicate that gains frames appear to be unhelpful in monitoring progress until catastrophic failure endangers the reference point, and that decision-makers often have more than one reference point to attune their policies to, which often results in suboptimal choices with regard to at least one reference point.     

基于稀疏表示和非参数判别分析的降维算法

针对人脸识别问题提出一种新的监督降维算法。算法首先基于稀疏表示理论,利用同类样本间的稀疏重构来构建图。此方案不仅可以克服传统图构造方法中参数选择的困难,而且能够更好地刻画类内信息。然后,算法采用非参数类间离差来刻画类间信息,非参数类间离差在处理复杂分布数据时相比于参数类间离差更具判别力。最后,算法通过保持类内稀疏重构关系的同时最大化非参数类间离差来求得最优的投影矩阵。在ORL和Extended Yale B公共人脸数据库的实验表明,该算法能够获得较好的识别结果。     

Joint pricing,assortment, and inventory decisions for a retailer's product line

Consider a set of product variants that are differentiated by some secondary attributes such as flavor, color, or size. The retailer's problem is to jointly determine the set of variants to include in her product line (“assortment”), together with their prices and inventory levels, so as to maximize her expected profit. We model the consumer choice process using a multinomial logit choice model and consider a newsvendor type inventory setting. We derive the structure of the optimal assortment for some important special cases, including the case of horizontally differentiated items, and propose a dominance relationship for the general case that simplifies the search for an optimal assortment. We also discuss structural properties of the optimal prices. Finally, motivated by our analytical results, we propose a heuristic solution procedure, which is shown to be quite effective through a numerical study. © 2007 Wiley Periodicals, Inc.

Pricing bridges to cross a river

We consider a pricing problem in directed, uncapacitated networks. Tariffs must be defined by an operator, the leader, for a subset of m arcs, the tariff arcs. Costs of all other arcs in the network are assumed to be given. There are n clients, the followers, and after the tariffs have been determined, the clients route their demands independent of each other on paths with minimal total cost. The problem is to find tariffs that maximize the operator's revenue. Motivated by applications in telecommunication networks, we consider a restricted version of this problem, assuming that each client utilizes at most one of the operator's tariff arcs. The problem is equivalent to pricing bridges that clients can use in order to cross a river. We prove that this problem is APX‐hard. Moreover, we analyze the effect of uniform pricing, proving that it yields both an m approximation and a (1 + lnD)‐approximation. Here, D is upper bounded by the total demand of all clients. In addition, we consider the problem under the additional restriction that the operator must not reject any of the clients. We prove that this problem does not admit approximation algorithms with any reasonable performance guarantee, unless P = NP, and we prove the existence of an n‐approximation algorithm. © 2007 Wiley Periodicals, Inc.
