An Analysis of Successful and Unsuccessful Terrorist Assassinations: Informing Counterterrorism Through Situational Crime Prevention

This study applies environmental criminology and situational crime prevention (SCP) to study successful and unsuccessful assassinations by terrorists. Using these perspectives, a series of hypotheses were devised to understand the situational factors that contribute to successful compared to unsuccessful assassinations. A random sample of roughly 1,000 successful and 1,000 unsuccessful assassination attacks taking place between 2005 and 2014 was acquired from the Global Terrorism Database (GTD). Open source materials were then consulted to supplement the GTD with the creation of new SCP variables. The hypotheses were tested in a binary logistic regression, and additional regression models were created for 4 specific regions (the Middle East & North Africa, South Asia, Southeast Asia, and Sub Saharan Africa). Results indicate support for the application of SCP and environmental criminology to the study of assassinations by terrorists. Specifically, successful assassinations are associated with guardianship, weapon type, target location, terrorist location, attack intensity, and distance. Findings are largely consistent across the different regions, however, the results from each regional model deviated slightly from the full model, indicating that the impact of certain SCP variables on successful assassinations vary by region

Situational crime prevention and worldwide piracy: a cross‑continent analysis

Relying on situational crime prevention perspective, this study compares successful and unsuccessful pirate attacks reported to the International Maritime Bureau (IMB) from the year 2000 through 2013 (n = 4,902). The study builds upon the recent work of Shane and Magnuson in Justice Quarterly, pp 1–26 (2014), which found various SCP techniques effectively prevented piracy attacks on a global level. The current study builds upon these findings by testing whether the global effect of SCP is consistent across individual continents. A series of mixed-effects logistic regression models and follow-up likelihood ratio tests were incorporated to explore the research question. In each model, SCP techniques were associated with unsuccessful piracy attacks on a global level. When considered individually, SCP techniques were equally effective in each continent. However, the use of multiple techniques classified within the increased effort technique of SCP was associated with increased likelihood of unsuccessful attacks in only 3 (South East Asia, Far East, and Rest of the World) of the 6 continents included in this study. The implications of these findings are discussed

SARS-CoV-2 susceptibility and COVID-19 disease severity are associated with genetic variants affecting gene expression in a variety of tissues

Variability in SARS-CoV-2 susceptibility and COVID-19 disease severity between individuals is partly due to genetic factors. Here, we identify 4 genomic loci with suggestive associations for SARS-CoV-2 susceptibility and 19 for COVID-19 disease severity. Four of these 23 loci likely have an ethnicity-specific component. Genome-wide association study (GWAS) signals in 11 loci colocalize with expression quantitative trait loci (eQTLs) associated with the expression of 20 genes in 62 tissues/cell types (range: 1:43 tissues/gene), including lung, brain, heart, muscle, and skin as well as the digestive system and immune system. We perform genetic fine mapping to compute 99% credible SNP sets, which identify 10 GWAS loci that have eight or fewer SNPs in the credible set, including three loci with one single likely causal SNP. Our study suggests that the diverse symptoms and disease severity of COVID-19 observed between individuals is associated with variants across the genome, affecting gene expression levels in a wide variety of tissue types

COVID-19 Host Genetics Initiative. A first update on mapping the human genetic architecture of COVID-19

The COVID-19 pandemic continues to pose a major public health threat, especially in countries with low vaccination rates. To better understand the biological underpinnings of SARS-CoV-2 infection and COVID-19 severity, we formed the COVID-19 Host Genetics Initiative1. Here we present a genome-wide association study meta-analysis of up to 125,584 cases and over 2.5 million control individuals across 60 studies from 25 countries, adding 11 genome-wide significant loci compared with those previously identified2. Genes at new loci, including SFTPD, MUC5B and ACE2, reveal compelling insights regarding disease susceptibility and severity.</p
