A Framework for Analyzing the Economic Tradeoffs Between Urban Commerce and Security Against Terrorism

This article presents a framework for economic consequence analysis of terrorism countermeasures. It specifies major categories of direct and indirect costs, benefits, spillover effects, and transfer payments that must be estimated in a comprehensive assessment. It develops a spreadsheet tool for data collection, storage, and refinement, as well as estimation of the various components of the necessary economic accounts. It also illustrates the usefulness of the framework in the first assessment of the tradeoffs between enhanced security and changes in commercial activity in an urban area, with explicit attention to the role of spillover effects. The article also contributes a practical user interface to the model for emergency managers.

The ‘affective security curriculum’: breeding JBs through the marriage of the academic and the jingoistic

How does the US recruit its citizen spies used to maintain and proliferate coercive power? I use an interdisciplinary approach and a framework of affect theory to argue that there is an ‘affective security curriculum’ (ASC) that assists in explaining the tendencies towards jingoism used in the recruitment and indoctrination of students – as future security workers – in certain academic disciplines. The ASC is precisely the phenomenon that works to construct this expert class and is produced by order words, the most crucial of which is ‘terrorism’, as well as larger cultural norms linked to neoliberalism that have achieved near total dominance since the 1980s. The ASC works by intensifying the (in)ability to act for those in its domain. The necessity of linguistically proficient security workers to the US’ hegemonic project makes this a question of considerable political importance. The ASC is a different approach to answering questions of how US hegemony is maintained. Whereas positivist research agendas, such as content analysis, and postpositivist approaches, such as critical discourse analysis, certainly have their uses (and to which my notion of ASC is indebted), paradigms such as these fail to focus on the engendering processes at work vis-à-vis the expert class, without which the discursive frames such methodologies analyse would simply dissipate. My overarching purpose in this paper is to develop the concept of the ASC, its quiddity, and to present at least an incipient methodology for analysing its critical duties. As my primary intent is to introduce and conceptualize the theoretical framework of the affective security curriculum, the applied segment of this endeavour will be relatively brief – and is designed as a primer for further research.     

Perceptions of Randomized Security Schedules

Security of infrastructure is a major concern. Traditional security schedules are unable to provide omnipresent coverage; consequently, adversaries can exploit predictable vulnerabilities to their advantage. Randomized security schedules, which randomly deploy security measures, overcome these limitations, but public perceptions of such schedules have not been examined. In this experiment, participants were asked to make a choice between attending a venue that employed a traditional (i.e., search everyone) or a random (i.e., a probability of being searched) security schedule. The absolute probability of detecting contraband was manipulated (i.e., 1/10, 1/4, 1/2) but equivalent between the two schedule types. In general, participants were indifferent to either security schedule, regardless of the probability of detection. The randomized schedule was deemed more convenient, but the traditional schedule was considered fairer and safer. There were no differences between traditional and random schedule in terms of perceived effectiveness or deterrence. Policy implications for the implementation and utilization of randomized schedules are discussed.     

Identifying Changing Aviation Threat Environments Within an Adaptive Homeland Security Advisory System

A critical component of aviation security consists of screening passengers and baggage to protect airports and aircraft from terrorist threats. Advancements in screening device technology have increased the ability to detect these threats; however, specifying the operational configurations of these devices in response to changes in the threat environment can become difficult. This article proposes to use Fisher information as a statistical measure for detecting changes in the threat environment. The perceived risk of passengers, according to prescreening information and behavior analysis, is analyzed as the passengers sequentially enter the security checkpoint. The alarm responses from the devices used to detect threats are also analyzed to monitor significant changes in the frequency of threat items uncovered. The key results are that this information‐based measure can be used within the Homeland Security Advisory System to indicate changes in threat conditions in real time, and provide the flexibility of security screening detection devices to responsively and automatically adapt operational configurations to these changing threat conditions.     

Extending social security coverage to the rural sector in China

In late 2009 China launched an innovative, voluntary programme that by 2011 had extended pension coverage to 326.4 million people in the rural sector, including contributors and beneficiaries. It requires one contribution per year and provides a flat‐rate benefit and a contributions‐related benefit through a contributory individual account, with a government guarantee that the benefit will continue for life. The programme encourages participation of persons who do not pay income taxes, and thus have no tax incentive to participate, by providing substantial government subsidies. As a further incentive, old‐age benefits are provided to older parents when all their adult children participate in the contributory programme.

联盟信任变迁与美韩联盟转型

联盟信任与联盟困境之间存在密切关系。在双边不对称联盟中,联盟困境的"抛弃"与"牵连"对联盟信任的作用更为强烈,进而成为推动联盟转型的重要变量。在美韩联盟发展过程中,其联盟信任不断变迁。联盟初期,由战火锤炼铸就的美韩双向情绪性信任,中经"尼克松冲击"转变为情绪性—工具性信任,后冷战时代历经双方的战略调整与实力变迁影响,转为双向工具性信任。受联盟信任变迁的影响,美韩联盟也实现了由军事联盟向战略性联盟的转变,这是联盟信任下降与共有利益拓展的共同结果。
