Pump and Dumps in the Bitcoin Era: Real Time Detection of Cryptocurrency Market Manipulations
In the last years, cryptocurrencies are increasingly popular. Even people who
are not experts have started to invest in these securities and nowadays
cryptocurrency exchanges process transactions for over 100 billion US dollars
per month. However, many cryptocurrencies have low liquidity and therefore they
are highly prone to market manipulation schemes. In this paper, we perform an
in-depth analysis of pump and dump schemes organized by communities over the
Internet. We observe how these communities are organized and how they carry out
the fraud. Then, we report on two case studies related to pump and dump groups.
Lastly, we introduce an approach to detect the fraud in real time that
outperforms the current state of the art, so to help investors stay out of the
market when a pump and dump scheme is in action.Comment: Accepted for publication at The 29th International Conference on

Transforming Conservation
There are severe problems with the decision-making processes currently widely used, leading to ineffective use of evidence, faulty decisions, wasting of resources and the erosion of public and political support. In this book an international team of experts provide solutions.
The transformation suggested includes rethinking how evidence is assessed, combined, communicated and used in decision-making; using effective methods when asking experts to make judgements (i.e. avoiding just asking an expert or a group of experts!); using a structured process for making decisions that incorporate the evidence and having effective processes for learning from actions. In each case, the specific problem with decision making is described with a range of practical solutions.
Adopting this approach to decision-making requires societal change so detailed suggestions are made for transforming organisations, governments, businesses, funders and philanthropists. The practical suggestions include twelve downloadable checklists.
The vision of the authors is to transform conservation so it is more effective, more cost-efficient, learns from practice and is more attractive to funders. However, the lessons of this important book go well beyond conservation to decision-makers in any field

Understanding evolutionary processes during past Quaternary climatic cycles: Can it be applied to the future?
Climate change affected ecological community make-up during the Quaternary which was probably both the cause of, and was caused by, evolutionary processes such as species evolution, adaptation and extinction of species and populations
