Trust realisation in multi-domain collaborative environments

In the Internet-age, the geographical boundaries that have previously impinged upon inter-organisational collaborations have become decreasingly important. Of more importance for such collaborations is the notion and subsequent nature of trust - this is especially so in Grid-like environments where resources are both made available and subsequently accessed and used by remote users from a multitude of institutions with a variety of different privileges spanning across the collaborating resources. In this context, the ability to dynamically negotiate and subsequently enforce security policies driven by various levels of inter-organisational trust is essential. In this paper we present a dynamic trust negotiation (DTN) model and associated prototype implementation showing the benefits and limitations DTN incurs in supporting n-tier delegation hops needed for trust realisation in multi-domain collaborative environments

Privacy, security, and trust issues in smart environments

Recent advances in networking, handheld computing and sensor technologies have driven forward research towards the realisation of Mark Weiser's dream of calm and ubiquitous computing (variously called pervasive computing, ambient computing, active spaces, the disappearing computer or context-aware computing). In turn, this has led to the emergence of smart environments as one significant facet of research in this domain. A smart environment, or space, is a region of the real world that is extensively equipped with sensors, actuators and computing components [1]. In effect the smart space becomes a part of a larger information system: with all actions within the space potentially affecting the underlying computer applications, which may themselves affect the space through the actuators. Such smart environments have tremendous potential within many application areas to improve the utility of a space. Consider the potential offered by a smart environment that prolongs the time an elderly or infirm person can live an independent life or the potential offered by a smart environment that supports vicarious learning

China’s Institutional Architecture: A New Institutional Economics and Organization Theory Perspective on the Links between Local Governance and Local Enterprises

We start our exploration of China’s institutional change by asking what the China experience can tell us about institutional economics and organization theory. We point to under-researched areas such as the formation of firms and the interplay between firms and local politics. Our findings support the dynamic capability approach which concentrates on activities rather than on pre-defined groups and models institution building as a co-operative game between the local business community and local government agencies. We find that the analysis of firms has to set in before they are formed by entrepreneurs and networks and we identify political management as a core competence of these two groups. While this contradicts the conventional view of clientelism or principle agent relations as institutional building blocks, we don’t propose competing models. Instead, we suggest focusing on a dynamic process in which the role of players can change. Faced with the spontaneous emergence of institutions, our concept of institutional architecture captures the fact that the two models can co-exist side by side and that, once the dichotomy between formal and informal institutions is given up, there can be a transition from local patron-client relations to local business-state coordination.entrepreneurship;dynamic capabilities;networks;institutional change;diversity and convergence of institutions

Electronic Mailing List and Internet Forums - Tools for Management and Marketing within Educational Organizations

This paper is about the use of Electronic Mailing List and Internet Forums as tools for managers within educational organizations. In the same time, some of concepts, ideas and models can be used in other business organizations, especially in service providing organizations. Understanding management requires both learning and practicing, directly experiencing. People involved in electronic networks are experiencing the alternative to real communication. We considered Electronic Mailing List and Internet Forums both as marketing tool and a human resources management tool. The benefits of using discussion lists are: people informed, involved and improved.electronic mailing list, internet forums, virtual groups, educational organization, educational tool, working groups

Coping with Extreme Events: Institutional Flocking

Recent measurements in the North Atlantic confirm that the thermohaline circulation driving the Gulf Stream has come to a stand. Oceanographic monitoring over the last 50 years already showed that the circulation was weakening. Under the influence of the large inflow of melting water in Northern Atlantic waters during last summer, it has now virtually stopped. Consequently, the KNMI and the RIVM estimate the average . In this essay we will explore how such a new risk profile affects the distribution of risks among societal groups, and the way in which governing institutions need to adapt in order to be prepared for situations of rapid but unknown change. The next section will first introduce an analytical perspective, building upon the Risk Society thesis and a proposed model of ‘institutional flocking’.temperature to decrease by 3°C in the next 15 years

Enforcement in Dynamic Spectrum Access Systems

The spectrum access rights granted by the Federal government to spectrum users come with the expectation of protection from harmful interference. As a consequence of the growth of wireless demand and services of all types, technical progress enabling smart agile radio networks, and on-going spectrum management reform, there is both a need and opportunity to use and share spectrum more intensively and dynamically. A key element of any framework for managing harmful interference is the mechanism for enforcement of those rights. Since the rights to use spectrum and to protection from harmful interference vary by band (licensed/unlicensed, legacy/newly reformed) and type of use/users (primary/secondary, overlay/underlay), it is reasonable to expect that the enforcement mechanisms may need to vary as well.\ud \ud In this paper, we present a taxonomy for evaluating alternative mechanisms for enforcing interference protection for spectrum usage rights, with special attention to the potential changes that may be expected from wider deployment of Dynamic Spectrum Access (DSA) systems. Our exploration of how the design of the enforcement regime interacts with and influences the incentives of radio operators under different rights regimes and market scenarios is intended to assist in refining thinking about appropriate access rights regimes and how best to incentivize investment and growth in more efficient and valuable uses of the radio frequency spectrum

Semantic security: specification and enforcement of semantic policies for security-driven collaborations

Collaborative research can often have demands on finer-grained security that go beyond the authentication-only paradigm as typified by many e-Infrastructure/Grid based solutions. Supporting finer-grained access control is often essential for domains where the specification and subsequent enforcement of authorization policies is needed. The clinical domain is one area in particular where this is so. However it is the case that existing security authorization solutions are fragile, inflexible and difficult to establish and maintain. As a result they often do not meet the needs of real world collaborations where robustness and flexibility of policy specification and enforcement, and ease of maintenance are essential. In this paper we present results of the JISC funded Advanced Grid Authorisation through Semantic Technologies (AGAST) project (www.nesc.ac.uk/hub/projects/agast) and show how semantic-based approaches to security policy specification and enforcement can address many of the limitations with existing security solutions. These are demonstrated into the clinical trials domain through the MRC funded Virtual Organisations for Trials and Epidemiological Studies (VOTES) project (www.nesc.ac.uk/hub/projects/votes) and the epidemiological domain through the JISC funded SeeGEO project (www.nesc.ac.uk/hub/projects/seegeo)

Governance-technology co-evolution and misalignment in the electricity industry

This paper explores some reasons why the alignment between governance and technology in infrastructures may be unstable or not easy to achieve. Focusing on the electricity industry, we claim that the decentralization of governance – an essential step towards a decentralized technical coordination - may be hampered by if deregulation magnifies behavioural uncertainties and asset specificities; and that in a technically decentralized system, political demand for centralized coordination may arise if the players are able to collude and lobby, and if such practices lead to higher electricity rates and lower efficiency. Our claims are supported by insights coming from approaches as diverse as transaction cost economics, the competence-based view of the firm, and political economy.Governance; Technology; Coherence; Competence; Transaction costs; Regulation.

The Open Research Web: A Preview of the Optimal and the Inevitable

The multiple online research impact metrics we are developing will allow the rich new database , the Research Web, to be navigated, analyzed, mined and evaluated in powerful new ways that were not even conceivable in the paper era – nor even in the online era, until the database and the tools became openly accessible for online use by all: by researchers, research institutions, research funders, teachers, students, and even by the general public that funds the research and for whose benefit it is being conducted: Which research is being used most? By whom? Which research is growing most quickly? In what direction? under whose influence? Which research is showing immediate short-term usefulness, which shows delayed, longer term usefulness, and which has sustained long-lasting impact? Which research and researchers are the most authoritative? Whose research is most using this authoritative research, and whose research is the authoritative research using? Which are the best pointers (“hubs”) to the authoritative research? Is there any way to predict what research will have later citation impact (based on its earlier download impact), so junior researchers can be given resources before their work has had a chance to make itself felt through citations? Can research trends and directions be predicted from the online database? Can text content be used to find and compare related research, for influence, overlap, direction? Can a layman, unfamiliar with the specialized content of a field, be guided to the most relevant and important work? These are just a sample of the new online-age questions that the Open Research Web will begin to answer

Economic Organization in the Knowledge Economy Some Austrian Insights

I critically discuss recent claims about economic organization in the emerging “knowledge economy,” specifically that authority relations will tend to disappear (or at least become radically transformed), the boundaries of the firm will blur, and coordination mechanisms will be much more malleable than assumed in organizational economics, resulting in various “new organizational forms.” In particular, the price mechanism will be used inside hierarchies to a much greater extent. In order to obtain an analytical focus on the knowledge economy, I assume that it may be approximated by “Hayekian settings” (after Hayek 1945), that is, settings in which knowledge is distributed and where knowledge inputs are relatively more important in production than physical capital inputs. I then argue, drawing on organizational economics as well as Mises’ insights in property rights and comparative systems, that the presence of Hayekian settings does not mean that authority will disappear, etc., although economic organization will in fact be affected by the emergence of the knowledge economy. This suggests that Austrian economics has an important contribution to make to the study of economic organization.Economic organizations, Austrian economics
