Discovering Scholarly Orphans Using ORCID
Archival efforts such as (C)LOCKSS and Portico are in place to ensure the
longevity of traditional scholarly resources like journal articles. At the same
time, researchers are depositing a broad variety of other scholarly artifacts
into emerging online portals that are designed to support web-based
scholarship. These web-native scholarly objects are largely neglected by
current archival practices and hence they become scholarly orphans. We
therefore argue for a novel paradigm that is tailored towards archiving these
scholarly orphans. We are investigating the feasibility of using Open
Researcher and Contributor ID (ORCID) as a supporting infrastructure for the
process of discovery of web identities and scholarly orphans for active
researchers. We analyze ORCID in terms of coverage of researchers, subjects,
and location and assess the richness of its profiles in terms of web identities
and scholarly artifacts. We find that ORCID currently lacks in all considered
aspects and hence can only be considered in conjunction with other discovery
sources. However, ORCID is growing fast so there is potential that it could
achieve a satisfactory level of coverage and richness in the near future.Comment: 10 pages, 5 figures, 5 tables accepted for publication at JCDL 201
Pointwise intersection in neighbourhood modal logic
We study the logic of neighbourhood models with pointwise intersection, as a
means to characterize multi-modal logics. Pointwise intersection takes us from
a set of neighbourhood sets (one for each member of a set
, used to interpret the modality ) to a new neighbourhood set
, which in turn allows us to interpret the operator .
Here, is in the neighbourhood for if and only if equals the
intersection of some . We show that the
notion of pointwise intersection has various applications in epistemic and
doxastic logic, deontic logic, coalition logic, and evidence logic. We then
establish sound and strongly complete axiomatizations for the weakest logic
characterized by pointwise intersection and for a number of variants, using a
new and generally applicable technique for canonical model construction.Comment: Submitted to Advances in Modal Logic 201
Extending Sitemaps for ResourceSync
The documents used in the ResourceSync synchronization framework are based on
the widely adopted document format defined by the Sitemap protocol. In order to
address requirements of the framework, extensions to the Sitemap format were
necessary. This short paper describes the concerns we had about introducing
such extensions, the tests we did to evaluate their validity, and aspects of
the framework to address them.Comment: 4 pages, 6 listings, accepted at JCDL 201
Gravitational wave energy spectrum of hyperbolic encounters
The emission of gravitational waves is studied for a system of massive
objects interacting on hyperbolic orbits within the quadrupole approximation
following the work of Capozziello et al. Here we focus on the derivation of an
analytic formula for the energy spectrum of the emitted waves. We checked
numerically that our formula is in agreement with the two limiting cases for
which results were already available: for the eccentricity {\epsilon} = 1, the
parabolic case whose spectrum was computed by Berry and Gair, and the large
{\epsilon} limit with the formula given by Turner.Comment: 9 pages, 4 figures, Accepted for publication in Physical Review

The effects of trust on performance of high-tech business relationships
We investigate the effects of trust propensity, cognition based trust and affect based trust on relationship performance in terms of openness, conflicts and success. Data from a field study of 391 Dutch firms in high tech industries support the research model. Trust that derives from affection is key and outweighs cognition based trust and trust propensity. Openness increases success that in turn fosters the development of affect based trust. The results provide preliminary but convincing evidence for the value of relational capital in durable business relationships that strive for the development of new technological knowledge.
