Next‐Generation Sequencing of the Bacterial 16S rRNA Gene for Forensic Soil Comparison: A Feasibility Study

Soil has the potential to be valuable forensic evidence linking a person or item to a crime scene; however, there is no established soil individualization technique. In this study, the utility of soil bacterial profiling via next‐generation sequencing of the 16S rRNA gene was examined for associating soils with their place of origin. Soil samples were collected from ten diverse and nine similar habitats over time, and within three habitats at various horizontal and vertical distances. Bacterial profiles were analyzed using four methods: abundance charts and nonmetric multidimensional scaling provided simplification and visualization of the massive datasets, potentially aiding in expert testimony, while analysis of similarities and k‐nearest neighbor offered objective statistical comparisons. The vast majority of soil bacterial profiles (95.4%) were classified to their location of origin, highlighting the potential of bacterial profiling via next‐generation sequencing for the forensic analysis of soil samples.     

From Balcony to Barricade: Nationalism and Popular Mobilisation in Georgia,Ukraine, and Russia

This article examines the dynamics of popular mobilisation in autocratic post-communist regimes, focusing on how opposition groups manoeuvre around cultural and structural constraints to inspire ordinary citizens to join street protests, despite the real dangers associated with political action. Using evidence from original interviews with activists in Georgia, Ukraine, and Russia, the article analyses the comparative challenges facing Russian activists in constructing new collective identities for the people they hope will become their followers, through the use of an inclusive, civic nationalism and a narrative that links action in the present to an ongoing, shared historical process.     

Testing types: A review and test of police types

This paper offers a review and comparison of five major typologies of individual police officers, concluding with the suggestion that the five typologies contain a total of four major distinct types. An independent data set is then used in a secondary analysis to test empirically the existence of the four generic types. The test results provide nothing to support the notion that the four types actually exist; no empirical counterpart was found for any of the hypothesized generic types.
