Forming perceptions and the limits to public participation on ocean commons: evidence from a citizens jury workshop

Alyne Elizabeth Delaney, Maria Hadjimichael
2017 International Journal of the Commons  
Stakeholder opinions uncovered through workshop discussions also show how commons are viewed today -as an economic resource -highlighting the trend of the mainstreaming of the commodification of the commons  ...  As this article reveals, the lessons learned from the Dogger Bank workshop advocate not simply what is required for managing one particular ocean commons, but also highlight some of the public participation  ...  After presenting our analysis of the workshop, we conclude with our view on limits to public participation in management of ocean commons.  ...

Due to poor signal strength, multipath e↵ects, and limited on-device computation power, common GPS receivers do not work indoors.  ...  By leveraging the computing power of the cloud, we accommodate longer signals for acquisition, and remove the requirement of decoding timestamps or ephemeris data from GPS signals.  ...  Some complementary techniques can further improve the accuracy of COIN-GPS.  ...

Initial Coin Offerings

Paul P. Momtaz, Renuka Sane
2020 PLoS ONE  
This paper examines the market for initial coin offerings (ICOs).  ...  I find that the ICO market is highly susceptible to such environmental shocks, resulting in substantial welfare losses for investors.  ...  While these limitations are necessary to avoid biases of the models' internal validity, they reduce the generalizability of the results.  ...

Private coins versus public coins in interactive proof systems

S Goldwasser, M Sipser
1986 Proceedings of the eighteenth annual ACM symposium on Theory of computing - STOC '86  
An interactive proof system is a method by which one party of unlimited resources, called the prover, can convince a party of limited resources, call the verifier, of the truth of a proposition.  ...  This extends the familiar proof system implicit in the notion of NP in that there the verifier may not toss coins or speak, but only listen and verify.  ...  Acknowledgements We are grateful to Oded Goldreich and Johan Hastad for pointing out that our proof works for a polynomial number of interactions.  ...
