Terrorist attacks are events which hinder the development of a region. Before the terrorist attacks, we need to conduct a graded evaluation of the terrorist attacks. After getting the level of terrorist attacks, we can fight terrorist organizations more effectively. This paper builds rating models for terrorist attacks, hidden or emerging terrorist organization classification discovery models, terrorist organization alliance network models and more, through quantitative research of the Global Terrorism Database, which solved the event classification. Through studying relevant literature and the variables of the Global Terrorism Database, this paper sorted out 25 observation variables related to the impact level (level of harm) of terrorist attacks. By establishing a mathematical model of factor analysis, 11 factors related to the impact level (level of harm) of terrorist attacks were constructed, and the variance of the contribution of each factor was used as the weight to calculate the comprehensive rate of the impact level of each terrorist attack. Finally, K-means clustering method is used to cluster and analyze the comprehensive rate of impact level, and the top 10 terrorist attacks with the highest impact level in the past two decades were obtained.

AbstractTourism is one of the most important sector of the national economy and in the same time is the main reason for which the tourists visit the North African states. In 2015, the total contribution of North African tourism represent 10.8% from GDP registering an increase of 1.4% compared to 2014, also the contribution of tourism to employment was 10.4 % in 2015. But this increase was affected by the terrorist attacks in Algeria, Egypt, Libya, Morocco and Tunisia. According to Global Terrorism Index for 2016, these countries are in the ranking of states with the highest impact of terrorism. Security situation in 2015 is the following: 947 incidents, 1198 deaths, 1603 injured, 264 property damages. This situation greatly influences the decision of tourists to travel in these countries. For demonstrate what is the impact on terrorism in this region have been analized the data bases of World Travel and Tourism Council, Council and Foreign Relations and Global Terrorism Database for the period 2010-2015. If the terrorist attacks continue in the next years not only the tourism will be affected but also the activities of its associates.

The past years have witnessed increasingly widespread terrorism, violently destroying world peace and regional prosperity. Therefore, uncovering terrorist plots has become the most crucial step for eliminating terrorist attacks. However, with the terrorist scheme being disguised under the huge amount of data flow on the internet, identifying terrorist organizations still remains challenging. Since many terrorist organizations are prone to launch terrorist attacks together, here, we model their relationships as a Terrorist Organization Alliance (TOA) network and propose a novel method to identify the key terrorist organizations in the TOA network. The TOA network utilizes existing key nodes in order to extract useful information, and, with the help of the entropy weight method, the new solution to the TOA network is effective and precise. The experiments are performed on the dataset from the Global Terrorism Database, and the results are statistically validated through t-tests and convergence analysis. Compared with the traditional methods, our method is proven to be superior in terms of measure the harm of terrorist attack organizations and find the key terrorist organizations.

Terrorist attacks have become a serious source of risk affecting the security of the international community. Using the Global Terrorism Database (GTD), in order to quantitatively study past terrorist attacks and their temporal and spatial evolution the analytic hierarchy process (AHP) was used to classify the degree of damage from terrorist attacks. The various factors influencing terrorist attacks were extracted and represented in three dimensions. Subsequently, using MATLAB for analysis and processing, the grading standards for terrorist attacks were classified into five levels according to the degree of hazard. Based on this grading standard, the top ten terrorist attacks with the highest degree of hazard in the past two decades were listed. Because the characteristics and habits of a terrorist or group exhibit a certain consistency, the K-means cluster analysis method was used to classify terrorists according to region, type of attack, type of target and type of weapon used by the terrorists. Several attacks that might have been committed by the same terrorist organization or individual at different times and in different locations were classified into one category, and the top five categories were selected according to the degree of sabotage inflicted by the organization or individual. Finally, the spatiotemporal evolution of terrorist attacks in the past three years was analyzed, considering the terrorist attack targets and key areas of terrorist attacks. The Middle East, Southeast Asia, Central Asia, and Africa were predicted to be the regions that will be most seriously affected by future global terrorist events. The terrorist attacks in Southeast Asia are expected to become more severe, and the scope of terrorist attacks in Africa is expected to widen. Civilians are the targets most at risk for terrorist attacks, and the corresponding risk index is considerably higher than it is for other targets. The results of this research can help individuals and the government to enable a better understanding of terrorism, improve awareness to prevent terrorism and enhance emergency management and rescue, and provide a solid and reliable basis and reference for joint counterterrorism in various countries and regions.

The Impact

IntroductionMost of the literature on terrorist attacks’ health impacts has focused on direct victims rather than on distal consequences in the overall population. There is limited knowledge on how terrorist attacks can be detrimental to access to healthcare services. The objective of this study is to assess the impact of terrorist attacks on the utilisation of maternal healthcare services by examining the case of Burkina Faso.MethodsThis longitudinal quasi-experimental study uses multiple interrupted time series analysis. Utilisation of healthcare services data was extracted from the National Health Information System in Burkina Faso. Data span the period of January 2013–December 2018 and include all public primary healthcare centres and district hospitals. Terrorist attack data were extracted from the Armed Conflict Location and Event Data project. Negative binomial regression models were fitted with fixed effects to isolate the immediate and long-term effects of terrorist attacks on three outcomes (antenatal care visits, of facility deliveries and of cesarean sections).ResultsDuring the next month of an attack, the incidence of assisted deliveries in healthcare facilities is significantly reduced by 3.8% (95% CI 1.3 to 6.3). Multiple attacks have immediate effects more pronounced than single attacks. Longitudinal analysis show that the incremental number of terrorist attacks is associated with a decrease of the three outcomes. For every additional attack in a commune, the incidence of cesarean sections is reduced by 7.7% (95% CI 4.7 to 10.7) while, for assisted deliveries, it is reduced by 2.5% (95% CI 1.9 to 3.1) and, for antenatal care visits, by 1.8% (95% CI 1.2 to 2.5).ConclusionTerrorist attacks constitute a new barrier to access of maternal healthcare in Burkina Faso. The exponential increase in terrorist activities in West Africa is expected to have negative effects on maternal health in the entire region.

This paper investigates the impact of the recent terrorist attacks on the Turkish banking sector. Specifically, an event study analysis is executed to estimate the abnormal returns of banks’ stocks in Turkey. According to the results, negative and significant abnormal returns were observed on the event dates of terrorist attacks, those of which especially occurred at international points and touristic places. The study continues with a regression analysis that looks into the cross-bank variation of abnormal returns by using important bank characteristics as predictors. The regression analysis exhibits that banks with higher leverage and larger size are prone to getting more negatively affected by the terrorist attack. On the other hand, banks with higher liquidity and higher income level are likely to have less negative abnormal returns.

Global Terrorism Database

We study the spatiotemporal correlation of terrorist attacks by al-Qaeda, the Islamic State of Iraq and Syria (ISIS), and local insurgents, in six geographical areas identified via k-means clustering applied to the Global Terrorism Database. All surveyed organizations exhibit near-repeat activity whereby a prior attack increases the likelihood of a subsequent one by the same group within 20 km and on average 4 (al-Qaeda) to 10 (ISIS) weeks. Near-response activity, whereby an attack by a given organization elicits further attacks from a different one, is found to depend on the adversarial, neutral, or collaborative relationship between the two. When in conflict, local insurgents respond quickly to attacks by global terror groups while global terror groups delay their responses to local insurgents, leading to an asymmetric dynamic. When neutral or allied, attacks by one group enhance the response likelihood of the other, regardless of hierarchy. These trends arise consistently in all clusters for which data are available. Government intervention and spillover effects are also discussed; we find no evidence of outbidding. Understanding the regional dynamics of terrorism may be greatly beneficial in policy making and intervention design.

With over 14% of all terrorist attacks since 1970 targeting law enforcement, terrorist attacks on police is a problem in need of scholarly attention. Police serve as symbolic targets of the government and strategic targets of terrorist attacks, yet we know little about such attacks. This article explores terrorist attacks targeting police in heavily hit countries, drawing from the Global Terrorism Database. While Iraq and India have the most terrorist attacks targeting police, these countries also have a high number of terrorist attacks against all targets. To account for the total number of terrorist attacks, proportions are explored, finding Macedonia, Russia, and Georgia have the highest proportions of terrorist attacks targeting police between 1998 and 2010. A common thread among these heavily hit countries is a rapidly changing governing regime coupled with societal schism—in other words, these countries seem to share low governmental legitimacy. Implications for future research are discussed.

This paper investigates how counterterrorism targeting terrorist leaders affects terrorist attacks. This effect is theoretically ambiguous and depends on whether terrorist groups are modeled as unitary actors or not. The paper exploits a natural experiment provided by strikes by Unmanned Aerial Vehicles (drones) “hitting” and “missing” terrorist leaders in Pakistan. Results suggest that terrorist groups increase the number of attacks they commit after a drone “hit” on their leader compared with after a “miss.” This increase is statistically significant for 3 out of 6 months after a hit, when it ranges between 47.7% and 70.3%. Additional analysis of heterogenous effects across groups and leaders, and the impact of drone hits on the type of attack, terrorist group infighting, and splintering, suggest that principal-agent problems—(new) terrorist leaders struggling to control and discipline their operatives—account for these results better than alternative theoretical explanations.

Research on terrorism in democracies borrows from the literature on civil war and rebellion to argue that more proportional representation decreases the likelihood of terrorist violence. However, theories of broader social mobilization may be ill-suited to predicting the occurrence of terrorism. This article proposes that proportionalism's institutionalization of small minority groups as legitimate but relatively insignificant political actors leads to militancy. Analyses of the Global Terrorism Database on domestic terrorist attacks across all democracies in 1975–2007 provide broad support for this argument. The presence and greater degrees of proportionalism are significantly associated with greater levels of domestic terrorism when ethnic fractionalization within a given society increases. Moreover, domestic terrorism increases as the number of small parties represented in the legislature increases.

BackgroundA reduction in suicide in England and Wales has been reported after the attacks of 11 September 2001 in the USA. It may be plausible therefore to expect a much greater impact on suicide in the UK in response to the events of 7 July 2005, caused by the first suicide terrorist attack by Islamic extremists on British soil.AimsTo examine the effect of the 7 July 2005 terrorist attacks in London on suicide rates in England and Wales.MethodAnalysis of number of suicide (ICD–10 codes X60–X84) and undetermined injury deaths (ICD–10 codes Y10–Y34) reported in England and Wales in the 12 weeks before and after 7 July 2005. We used Shewhart Control Charts based on Poisson rates to explore adjusted daily and weekly suicide rates and rate differences with respect to 7 July 2005.ResultsA brief but significant reduction in daily suicide rate was observed a few days after the terrorist attack in London on 7 July 2005. Further reduction was also observed on the 21 July 2005, coinciding with the second wave of attacks. No similar reduction in suicide was seen during the same period in the previous 4 years. Poisson regression models with indicator variables for each day in July 2005 revealed a reduction of 40% of the expected daily rate for these 2 days only. We found no evidence of any longer-term effect on suicide.ConclusionsThe study findings are contrary to our expectation and only weakly support Durkheim's theory that periods of national threat lower the suicide rate through the impact on social cohesion. It is possible that previous experience of IRA terrorism in the UK may have limited the effect of the 7 July 2005 attacks on suicide in England and Wales. The shock value of suicide terrorism and its psychological potency appear to diminish over time as the tactic becomes overused.
