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 $\mathcal{N}_i$ (one for each member $i$ of a set $G$, used to interpret the modality $\square_i$) to a new neighbourhood set $\mathcal{N}_G$, which in turn allows us to interpret the operator $\square_G$. Here, $X$ is in the neighbourhood for $G$ if and only if $X$ equals the intersection of some $\mathcal{Y} = \{Y_i \mid i\in G\}$. 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.
