Do academic laboratories correspond to scientific communities? Evidence from a large European university.
Although acknowledged as central in the economic literature, the issue of intra academic collaboration has been, insofar, relatively overlooked. This paper fills this gap by stressing the importance of communities in academic research. By analysing the publication behavior of researchers from a large European scientific university, we argue that in certain cases, the community level constitutes a relevant level for analysing the collaborative nature of scientific investigation. Indeed, the reality of research collaborations doesnât always fit the institutional division of academic work provided by laboratories.Economics of Science, Knowledge Intensive Communities, Academic Collaborations, Social Network Analysis.
Hyperbolic Browsers: From GUI to KUI
This paper studies the development of web browsers and describes a hyperbolic browser, a dynamic browser that organizes information visually
Correlation Networks Among Currencies
By analyzing the foreign exchange market data of various currencies, we
derive a hierarchical taxonomy of currencies constructing minimal-spanning
trees. Clustered structure of the currencies and the key currency in each
cluster are found. The clusters match nicely with the geographical regions of
corresponding countries in the world such as Asia or East Europe, the key
currencies are generally given by major economic countries as expected.Comment: 12 pages, 3 figures, 1 tabl
On Secure Workflow Decentralisation on the Internet
Decentralised workflow management systems are a new research area, where most
work to-date has focused on the system's overall architecture. As little
attention has been given to the security aspects in such systems, we follow a
security driven approach, and consider, from the perspective of available
security building blocks, how security can be implemented and what new
opportunities are presented when empowering the decentralised environment with
modern distributed security protocols. Our research is motivated by a more
general question of how to combine the positive enablers that email exchange
enjoys, with the general benefits of workflow systems, and more specifically
with the benefits that can be introduced in a decentralised environment. This
aims to equip email users with a set of tools to manage the semantics of a
message exchange, contents, participants and their roles in the exchange in an
environment that provides inherent assurances of security and privacy. This
work is based on a survey of contemporary distributed security protocols, and
considers how these protocols could be used in implementing a distributed
workflow management system with decentralised control . We review a set of
these protocols, focusing on the required message sequences in reviewing the
protocols, and discuss how these security protocols provide the foundations for
implementing core control-flow, data, and resource patterns in a distributed
workflow environment
