release v1.0

This first release contains a simple EPIDEMES/SPR MORPHINE scenario implementation that simulates vaccination hesitancy dynamics.

In a nutshell, the scenario comprises of a synthetic population with individual attitudes being evaluated according to an interpretation of the 4C model (Betsch et al., 2015) and propagated periodically across single-parent households in a social network. Peers are distributed evenly over subgroups, each subgroup having their own initial hesitancy attitude distributions and one attractor with its particular (extremist) view or attitude taken into account to some extent by all subgroup members and schedulable to reflect influences from e.g. health authorities, social conformance or media campaigns. In between attitude propagation rounds, where peers reposition their attitude, each parent has their own relation frequency at which they activate the pressure from peers in their own static social network. Together the contact lists have an average degree of assortativity, here meaning the fraction of in-group vs. out-group peers, so that attitudes may propagate between as well as within subgroups.

Some remarks on this release:

• outbreaks of infectious disease spreading across the non-vaccinated population are not yet included.
• households are not yet assigned to geographical regions, even though 71486ned-TS-2010-2016.json containing Dutch sensus data on regional household compositions is contained in this release.
• statistics are configured by default to export to jdbc:h2:<path/to>/morphine, a local H2 database chosen for its portability and GUI, but any other JDBC database should fit the embedded JPA v2.1 provider (currently Hibernate ORM v5.1).
