Several new models of computation have emerged in the last few years, and many developments of traditional computational models have been proposed with the aim of taking into account the new demands of computer systems users and the new capabilities of computation engines. A new computational model, or a new feature in a traditional one, usually is reflected in a new family of programming languages, and new paradigms of software development.

DCM 2010, co-located with FLoC 2010, concerns Causality, Computation, and Physics, and aims to provide a forum for ideas about new computing means and models, with a particular emphasis on computational and causal models related to physics and biology. We believe that bringing together different approaches -- in a community with the strong foundational background characteristic of FLoC -- inevitably results in inspirational cross-boundary exchanges, and innovative further research.

Day two of this pre-FLoC 2010 workshop -- in the form of Quantum Information Science Scotland 2010 (QUISCO 2010) -- is given over to physics and quantum related computation. The content of day one is more typical of past DCM workshops -- covering a wide spectrum of topics related to the development of new computational models or new features for traditional computational models.

DCM 2010 attracted a full spectrum of excellent and innovative research papers, including twenty regular submissions and five invited talks. All the submissions were of a high quality, although scheduling constraints allowed just sixteen regular submissions to be accepted for presentation at the workshop. This volume contains the articles of fourteen of the talks presented, together with one from invited speaker Cristian Calude.

The co-chairs of DCM 2010 and QUISCO 2010 have many people to thanks for their help, including the DCM Steering Committee and the DCM 2010 Programme Committee (see below), and a number of external reviewers.

We would also like to thank the FLoC 2010 local organisers, and the FLoC Workshops Chair Philip Scott, for all their help with the organisation of DCM 2010.
