The paper applies survival analysis to identify the determinants of terrorist group duration. Our sample includes 367 terrorist organizations that operated during 1970–2007. Consistent with the theory, determinants of these groups’ survival include their tactics, size, ideological basis, region of operation, and base-country characteristics. Cross-sectional and panel estimates are provided. Ter...

Abstract:Terrorism is a phenomenon that has spread to almost all parts of the world in the late 20th century and the beginning of the 21th century to the extent that many Middle East-ern countries have been subjected to such violence and unrest; in fact, with the advent of science and technology, particularly the global spread of the Internet and social net-works, the face of terrorism ha...

empowering of terrorist groups in the middle east is the product of numerous reasons. one of the most important of these reasons is the competition between regional powers and their use of the leverage of terrorist groups in order to put pressure on each other. furthermore, immature and wrong policies of great powers like: the united states in militarization of the region have provided new just...

The events of September 11, 2001 have irrevocably altered the landscape of computer security. In the aftermath of these events, various urban legends and rumors have developed surrounding terrorists’ online activities. One such topic has been in the alleged use of electronic steganography, a method to covertly hide messages within another, by terror st groups. This paper provides an overview of...

Using data from the University of Maryland’s Global Terrorism Database II, this paper first provides information on the nature of terrorist incidents in India in the period 1998-2004: the Indian states that were worst affected by terrorist incidents and fatalities; the terrorist groups responsible for such incidents and their modus operandi. Next, the paper focuses on the issue of fatalities fr...

This paper proposed structural analysis and mathematical methods for destabilizing terrorist networks. The three different approaches are discussed for example: (i) cohesion analysis (such as cliques, n-cliques, n-clans and k-plex) to determine familiarity, robustness and reachability within subgroups in 9/11 terrorist network; (ii) role analysis (such as position role index) to determine criti...

In this thesis, we considered the costs and benefits of implementing Positive Passenger Bag Match (PPBM) an anti-terrorist measure to keep bombs out of checked luggage on US domestic passenger flights. We constructed a stochastic model for comparing the cost-effectiveness of three alternative approaches to PPBM: no PPBML implementation; a PPBM imlementation that is applied to 5% of passengers; ...

Recent terrorist attacks and several terror alerts have increased the need to investigate the behavioral consequences of these threats. This research-in-progress paper focuses on the motivational factors determining usage behavior of social network sites (SNS) in the aftermath of terrorist attacks. Based on terror management theory (TMT) and uses and gratifications theory (U&G), this paper argu...

In recent years, terrorist groups have used the WWW to spread their ideologies, disseminate propaganda, and recruit members. Studying the terrorist websites may help us understand the characteristics of these websites and predict terrorist activities. In this paper, we propose to apply network topological analysis methods on systematically collected the terrorist website data and to study the s...

Because terrorist organizations often operate in network forms where individual terrorists collaborate with each other to carry out attacks, we could gain valuable knowledge about the terrorist organizations by studying structural properties of such terrorist networks. However, previous studies of terrorist network structure have generated little actionable results. This is due to the difficult...
