Separating Agent-Functioning and Inter-Agent Coordination by Activated Modules: The DECOMAS Architecture
The embedding of self-organizing inter-agent processes in distributed
software applications enables the decentralized coordination system elements,
solely based on concerted, localized interactions. The separation and
encapsulation of the activities that are conceptually related to the
coordination, is a crucial concern for systematic development practices in
order to prepare the reuse and systematic integration of coordination processes
in software systems. Here, we discuss a programming model that is based on the
externalization of processes prescriptions and their embedding in Multi-Agent
Systems (MAS). One fundamental design concern for a corresponding execution
middleware is the minimal-invasive augmentation of the activities that affect
coordination. This design challenge is approached by the activation of agent
modules. Modules are converted to software elements that reason about and
modify their host agent. We discuss and formalize this extension within the
context of a generic coordination architecture and exemplify the proposed
programming model with the decentralized management of (web) service
infrastructures
Untangling the Web of E-Research: Towards a Sociology of Online Knowledge
e-Research is a rapidly growing research area, both in terms of publications
and in terms of funding. In this article we argue that it is necessary to
reconceptualize the ways in which we seek to measure and understand e-Research
by developing a sociology of knowledge based on our understanding of how
science has been transformed historically and shifted into online forms. Next,
we report data which allows the examination of e-Research through a variety of
traces in order to begin to understand how the knowledge in the realm of
e-Research has been and is being constructed. These data indicate that
e-Research has had a variable impact in different fields of research. We argue
that only an overall account of the scale and scope of e-Research within and
between different fields makes it possible to identify the organizational
coherence and diffuseness of e-Research in terms of its socio-technical
networks, and thus to identify the contributions of e-Research to various
research fronts in the online production of knowledge

Making sense of assets: Community asset mapping and related approaches for cultivating capacities
This working paper critically reviews some main aspects from asset based approaches highlights key strengths and weaknesses for future research/development. Drawing on a large body of reports and relevant literature we draw on different theoretical traditions and critiques, as well as practices and processes embedded within a broad range of approaches including, widely acknowledged frameworks such Asset Based Community Development (ABCD), Appreciative Inquiry (AI), Sustainable Livelihood Approaches (SLA) and Community Capitals Framework (CCF). Although these are presented as distinct approaches, there is a sense of evolution through them and many of them overlap (in terms of both theories and methodologies). We also include emerging frameworks, including geographical, socio-spatial, visual and creative approaches, stemming from a number of projects within AHRC’s Connected Communities programme and additional collaborations
The civic survey of Greater London: social mapping, planners and urban space in the early twentieth century
This paper examines work conducted between 1915 and 1919 by a group of architects and planners based at the Royal Institute of British Architects. The project, called the Civic Survey of Greater London, and the substantial collection of maps and diagrams that resulted from it are currently unknown in histories of mapping and planning, thus this paper offers a preliminary account and analysis of the work. The paper begins by assessing the development of surveying and mapping techniques in the nineteenth century with the aim of situating the Survey within broader historical trajectories. The following section of the paper examines the immediate context for the Survey, in particular the place of Patrick Geddes and his ideas. The third part of the paper focuses on the work of the Survey itself. The fourth part draws out key analytical threads in dialogue with a number of the maps of the Survey. The emphasis placed here is on exploring lines of continuity between the Civic Survey of Greater London and earlier techniques of representation and governmentality. The concluding section reflects briefly on the reasons for the Survey's subsequent relative obscurity and the importance of the project for later traditions of surveying
How are higher education institutions dealing with openness?. A survey of practices, beliefs, and strategies in five European countries
Open Education is on the agenda of half of the surveyed Higher Education Institutions (HEIs) in France, Germany, Poland, Spain and the United Kingdom. For the other half of HEIs, Open Education does not seem to be an issue, at least at the time of the data collection of the survey (spring 2015). This report presents results of a representative a survey of Higher Education institutions in five European countries (France, Germany, Poland, Spain and the United Kingdom) to enquire about their Open Education (OE) practices, beliefs and strategies (e.g MOOCs). It aims to provide evidence for the further development of OE to support the supports the Opening Up Communication (European Commission, 2013) and the renewed priority on Open Education, enabled by digital technologies, of ET2020
Information standards to support application and enterprise interoperability for the smart grid
Copyright @ 2012 IEEE.Current changes in the European electricity industry are driven by regulatory directives to reduce greenhouse gas emissions, at the same time as replacing aged infrastructure and maintaining energy security. There is a wide acceptance of the requirement for smarter grids to support such changes and accommodate variable injections from renewable energy sources. However the design templates are still emerging to manage the level of information required to meet challenges such as balancing, planning and market dynamics under this new paradigm. While secure and scalable cloud computing architectures may contribute to supporting the informatics challenges of the smart grid, this paper focuses on the essential need for business alignment with standardised information models such as the IEC Common Information Model (CIM), to leverage data value and control system interoperability. In this paper we present details of use cases being considered by National Grid, the GB transmission system operator for information interoperability in pan-network system management and planning.This study is financially supported by the National Grid, UK
Privacy, Visibility, Transparency, and Exposure
This essay considers the relationship between privacy and visibility in the networked information age. Visibility is an important determinant of harm to privacy, but a persistent tendency to conceptualize privacy harms and expectations in terms of visibility has created two problems. First, focusing on visibility diminishes the salience and obscures the operation of nonvisual mechanisms designed to render individual identity, behavior, and preferences transparent to third parties. The metaphoric mapping to visibility suggests that surveillance is simply passive observation, rather than the active production of categories, narratives, and, norms. Second, even a broader conception of privacy harms as a function of informational transparency is incomplete. Privacy has a spatial dimension as well as an informational dimension. The spatial dimension of the privacy interest, which the author characterizes as an interest in avoiding or selectively limiting exposure, concerns the structure of experienced space. It is not negated by the fact that people in public spaces expect to be visible to others present in those spaces, and it encompasses both the arrangement of physical spaces and the design of networked communications technologies. U.S. privacy law and theory currently do not recognize this interest at all. This essay argues that they should
Attack-Surface Metrics, OSSTMM and Common Criteria Based Approach to “Composable Security” in Complex Systems
In recent studies on Complex Systems and Systems-of-Systems theory, a huge effort has been put to cope with behavioral problems, i.e. the possibility of controlling a desired overall or end-to-end behavior by acting on the individual elements that constitute the system itself. This problem is particularly important in the “SMART” environments, where the huge number of devices, their significant computational capabilities as well as their tight interconnection produce a complex architecture for which it is difficult to predict (and control) a desired behavior; furthermore, if the scenario is allowed to dynamically evolve through the modification of both topology and subsystems composition, then the control problem becomes a real challenge. In this perspective, the purpose of this paper is to cope with a specific class of control problems in complex systems, the “composability of security functionalities”, recently introduced by the European Funded research through the pSHIELD and nSHIELD projects (ARTEMIS-JU programme). In a nutshell, the objective of this research is to define a control framework that, given a target security level for a specific application scenario, is able to i) discover the system elements, ii) quantify the security level of each element as well as its contribution to the security of the overall system, and iii) compute the control action to be applied on such elements to reach the security target. The main innovations proposed by the authors are: i) the definition of a comprehensive methodology to quantify the security of a generic system independently from the technology and the environment and ii) the integration of the derived metrics into a closed-loop scheme that allows real-time control of the system. The solution described in this work moves from the proof-of-concepts performed in the early phase of the pSHIELD research and enrich es it through an innovative metric with a sound foundation, able to potentially cope with any kind of pplication scenarios (railways, automotive, manufacturing, ...)
