Summary: This paper sets out an approach to Social Machines (SMs), their description
and analysis, based on a development of social constructionist theoretical
principles adapted for Web Science. We argue that currently the search for the
primitives of SMs, or appropriate units of analysis to describe them, tends to
favour either the technology or sociality. We suggest an approach that favours
distributed agency whether it is machinic or human or both. We argue that
current thinking (e.g. Actor Network Theory) is unsuited to SMs. Instead we
describe an alternative which prioritizes a view of socio-technical activity as
forming 'reflexive project structures'. We show that reflexivity in social
systems can be further usefully divided into more fundamental elements
(Recognition and Responsivity). This process enables us to capture more of the
variation in SMs and to distinguish them from non-Web based socio-technical
systems. We illustrate the approach by looking at different kinds of SMs
showing how they relate to contemporary social theory.

Summary: We have developed a new framework for supporting concurrency control in
collaborative applications. It supports multiple degrees of consistency and
allows users to choose concurrency control policies based on the objects they
are manipulating, the tasks they are performing, and the coupling and merge
policies they are using. Concurrency control policies are embodied in
hierarchical, constructor-based lock compatibility tables. Entries in these
tables may be specified explicitly or derived automatically from coupling and
merge policies. In this paper, we motivate and describe the framework,
identify several useful concurrency control policies it can support, evaluate
its flexibility, and give conclusions and directions for future work.

Summary: The need to merge different versions of an object to a common state arises
in collaborative computing due to several reasons including optimistic
concurrency control, asynchronous coupling, and absence of access control. We
have developed a flexible object merging framework that allows definition of
the merge policy based on the particular application and the context of the
collaborative activity. It performs automatic, semi-automatic, and interactive
merges, supports semantics-determined merges, operates on objects with
arbitrary structure and semantics, and allows fine-grained specification of
merge policies. It is based on an existing collaborative applications
framework and consists of a merge matrix, which defines merge functions and
their parameters and allows definition of multiple merge policies, and a merge
algorithm, which performs the merge based on the results computed by the merge
functions. In conjunction with our framework we introduce a set of merge
policies for several useful kinds of merges we have identified. This paper
motivates the need for a general approach to merging, identifies some important
merging issues, surveys previous research in merging, identifies a list of
merge requirements, describes our merging framework and illustrates it with
examples, and evaluates the framework with respect to the requirements and
other research efforts in merging objects.
