The increase in the number of terrorist attacks in Russia suggests that anti-terrorist policies have failed to solve the Chechen terrorist problem. The Putin paradox, named after Russia’s president Vladimir Putin, is the capacity of the incumbent government to maintain or even increase its popular support while suffering increasing terrorist attacks. This paper presents a dynamic model where go...

In this study, I investigated students' memories of the terrorist attacks of September 11, 2001, carried out by Al Qaeda terrorists against the World Trade Center in New York and the Pentagon in Washington. Participants completed on two occasions (2 weeks and 8 months after the events took place) a memory questionnaire that included an assessment of the phenomenal richness of their memories. Th...

Activity data accumulated in real life, e.g. in terrorist activities and fraudulent customer contacts, presents special structural and semantic complexities. However, it may lead to or be associated with significant business impacts. For instance, a series of terrorist activities may trigger a disaster to the society, large amounts of fraudulent activities in social security program may result ...

This paper highlights five areas where economic analysis of terrorism has had the greatest policy relevance during the last 30 years. These areas involve evaluating the effectiveness of counterterrorism actions, identifying the causes of terrorism, measuring the economic ramification of terrorism, analyzing the time-series dynamics of terrorist events, and formulating game-theoretic representat...

In this paper, we present algorithms for subgroup detection and demonstrated them with a real-time case study of USS Cole bombing terrorist network. The algorithms are demonstrated in an application by a prototype system. The system finds associations between terrorist and terrorist organisations and is capable of determining links between terrorism plots occurred in the past, their affiliation...

Public policies to mitigate the impacts of extreme events such as hurricanes or terrorist attacks will differ depending on whether they focus on reducing risk or reducing vulnerability. Here we present and defend six assertions aimed at exploring the benefits of vulnerability-based policies. (1) Risk-based approaches to covering the costs of extreme events do not depend for their success on red...

The R package Synth implements synthetic control methods for comparative case studies designed to estimate the causal effects of policy interventions and other events of interest (Abadie and Gardeazabal 2003; Abadie, Diamond, and Hainmueller 2010). These techniques are particularly well-suited to investigate events occurring at an aggregate level (i.e., countries, cities, regions, etc.) and aff...

The implementation of knowledge management practices has been underway in both the public and private sectors for many years. For the federal government this transition was well underway prior to the devastating events of September 11th, 2001 (9/11). However those events increased the awareness of the value and importance of the government’s stewardship of its knowledge. In fact, the 9/11 terro...

Recent geopolitical events, including the terrorist attacks on the United States on September 11, 2001, and ongoing military operations in Iraq, have raised awareness of the often severe psychological after-effects of these and other types of traumatic events. Post traumatic stress disorder (PTSD) represents the most severe of these sequelae. PTSD is an under-recognized and under-treated chroni...

"Pentagon Prepares a Futures Market on Terror Attacks" blared the headline in the New York Times above an article on the Pentagon's "policy analysis market" (PAM) project. The Pentagon intended to employ a "virtual stock market" — for the aggregation of information and derivation of forecasts — to help predict foreign-policy events such as a coup d'état in a particular country or terrorist atta...
