Gully and Stream Bank Toolbox. A technical guide for gully and stream bank erosion control programs in Great Barrier Reef catchments

This Toolbox is a guide to targeting, designing and implementing gully and stream bank erosion control activities in Great Barrier Reef (GBR) catchments. This third edition builds on 7 years of implementing these activities in multiple programs and it aims to inform the ongoing efforts to reduce the amount of fine sediment and associated nutrients delivered to the GBR lagoon. Sub‑soil erosion, predominantly from gullies and stream banks, contributes the vast bulk of the fine sediment load delivered to the GBR. The large area and extensive erosion in GBR catchments, and the limited resources available, make it important for erosion control to be targeted to cost‑effective sites and implemented using best practice based on best available information. Landholder support and site maintenance increase the likelihood that sediment reductions will persist over the long term

Fraud, Plot, or Collective Delusion? Social Media and Perceptions of Electoral Misconduct in the 2014 Scottish Independence Referendum

Online discussions of electoral fraud are becoming an increasingly important aspect of the electoral landscape in many contexts, as cyberspace is one of the few places where concerns about electoral conduct can be aired openly and freely. But it is often difficult to assess what this online activity tells us about actual electoral processes. This article analyzes a surge of tweets about electoral fraud at the time of the Scottish independence referendum of 2014 in order to ascertain whether this online activity reflected: (a) actual offline fraud observed by the social media users, (b) a concerted effort to undermine confidence in electoral administration, or (c) a collective delusion. Data mining and machine learning techniques are deployed in this analysis, which comes out strongly in favor of the collective delusion hypothesis.</p
