RT Article T1 To Blend in or Hide Out? A Network Analysis on Maritime Criminal Co-voyages in Taiwan JF Journal of quantitative criminology VO 40 IS 2 SP 373 OP 393 A1 Jiang, Yansheng A1 Chang, Yi-chun 1932- A1 Weng, Wei A2 Chang, Yi-chun 1932- A2 Weng, Wei LA English YR 2024 UL https://krimdok.uni-tuebingen.de/Record/1925590798 AB ObjectivesUnderstanding how covert networks are formed is key to disrupting the operation of illicit activities. Applying standard network measures to a covert network, while useful, is limited in identifying the peculiar properties of the network in question. It is important that we compare the covert network against a benchmark, be it random networks or, more ideally, the counterpart (overt) network in the same context. We report a study in collaboration with law enforcement agency to examine the co-voyage network of criminals and non-criminals. A comparison of the two groups of actors in their network positions allows us to test whether criminals tend to blend in or hide out from the population of non-criminals.MethodsDrawing on data on maritime activities in Taiwan recorded from years 2016 to 2018, we map a maritime co-voyage network of 53,009 nodes and 2,592,288 weighted links. We follow a bootstrap resampling procedure to estimate the structural features of the co-voyage networks of criminals and non-criminals.ResultsCriminals are more likely to co-voyage with their own type than non-criminals. Similarly, criminals are more clustered in the co-voyage network than non-criminals.ConclusionsIt is more supported that criminals segregate from than blend in non-criminals in the co-voyage network.
