Assessment of Self-Archiving in Institutional Repositories: Depositorship and Full-Text Availability
No full textThis research evaluates the success of open access self-archiving in several well-known institutional repositories. Two assessment factors have been applied to examine the current practice of self-archiving: depositorship and the availability of full text. This research discovers that the rate of author self-archiving is low and that the majority of documents have been deposited by a librarian or administrative staff. Similarly, the rate of full-text availability is relatively low, except for Australian repositories. By identifying different practices of self-archiving, repository managers can create new strategies for the operation of their repositories and the development of archiving policies

Applying the NISO Metasearch Initiative Scheme to Enhance E-Resources Management at Rutgers University Library
No full textThis paper discusses problems in the management of library e-resources and attempts to identify potential solutions to the problems. By describing an e-resources enhancement project taken by Rutgers University Libraries, this paper points to the importance of providing contextually-rich metadata and reorganizing the accessibility of e-resources on a library’s website. It introduces how this Rutgers project adopted the National Information Standards Organization Metasearch Initiative to support the identification of appropriate e-collections for metaseaching. The outcomes of the project have facilitated a dynamic display of relevant e-resources to library users as an effective way of automatic access to library e-collections.Peer reviewe
A Metadata Manager's Role in Collaborative Projects: The Rutgers University Libraries Experience
No full textPurpose – This article discusses the roles and responsibilities of a metadata manager in collaborative digital projects.
Methodology – It describes the general requirements for metadata management, and introduces some scenarios in the practices of digital projects by the Rutgers University Libraries to support the generalized definition. A workflow of metadata management is illustrated.
Practical implications – With an explicit definition of the roles and responsibilities of the metadata manager, many other digital libraries that need to develop a new or optimize the existing workflow may find the Rutgers experience useful as reference.
Originality – Very few articles have explored this topic although the functions of metadata in the development of digital projects have been talked extensively.Peer reviewe

Extension of the sun-synchronous Orbit
No full textThrough careful consideration of the orbit perturbation force due to the oblate nature of the primary body a secular variation of the ascending node angle of a near-polar orbit can be induced without expulsion of propellant. Resultantly, the orbit perturbations can be used to maintain the orbit plane in, for example, a near-perpendicular (or at any other angle) alignment to the Sun-line throughout the full year of the primary body; such orbits are normally termed Sun-synchronous orbits [1, 2]. Sun-synchronous orbits about the Earth are typically near-circular Low-Earth Orbits (LEOs), with an altitude of less than 1500 km. It is normal to design a LEO such that the orbit period is synchronised with the rotation of the Earth‟s surface over a given period, such that a repeating ground-track is established. A repeating ground-track, together with the near-constant illumination conditions of the ground-track when observed from a Sun-synchronous orbit, enables repeat observations of a target over an extended period under similar illumination conditions [1, 2]. For this reason, Sun-synchronous orbits are extensively used by Earth Observation (EO) platforms, including currently the Environmental Satellite (ENVISAT), the second European Remote Sensing satellite (ERS-2) and many more. By definition, a given Sun-synchronous orbit is a finite resource similar to a geostationary orbit. A typical characterising parameter of a Sun-synchronous orbit is the Mean Local Solar Time (MLST) at descending node, with a value of 1030 hours typical. Note that ERS-1 and ERS-2 used a MLST at descending node of 1030 hours ± 5 minutes, while ENVISAT uses a 1000 hours ± 5 minutes MLST at descending node [3]. Following selection of the MLST at descending node and for a given desired repeat ground-track, the orbit period and hence the semi-major axis are fixed, thereafter assuming a circular orbit is desired it is found that only a single orbit inclination will enable a Sun-synchronous orbit [2]. As such, only a few spacecraft can populate a given repeat ground-track Sun-synchronous orbit without compromise, for example on the MLST at descending node. Indeed a notable feature of on-going studies by the ENVISAT Post launch Support Office is the desire to ensure sufficient propellant remains at end-of-mission for re-orbiting to a graveyard orbit to ensure the orbital slot is available for future missions [4]. An extension to the Sun-synchronous orbit is considered using an undefined, non-orientation constrained, low-thrust propulsion system. Initially the low-thrust propulsion system will be considered for the free selection of orbit inclination and altitude while maintaining the Sun-synchronous condition. Subsequently the maintenance of a given Sun-synchronous repeat-ground track will be considered, using the low-thrust propulsion system to enable the free selection of orbit altitude. An analytical expression will be developed to describe these extensions prior to then validating the analytical expressions within a numerical simulation of a spacecraft orbit. Finally, an analysis will be presented on transfer and injection trajectories to these orbits
Species diversity, systematic revision and molecular phylogeny of Ganodermataceae (Polyporales, Basidiomycota) with an emphasis on Chinese collections
No full textGanodermataceae is one of the main families of macrofungi since species in the family are both ecologically and economically important. The double-walled basidiospores with ornamented endospore walls are the characteristic features of Ganodermataceae. It is a large and complex family; although many studies have focused on Ganodermataceae, the global diversity, geographic distribution, taxonomy and molecular phylogeny of Ganodermataceae still remained incompletely understood. In this work, taxonomic and phylogenetic studies on worldwide species of Ganodermataceae were carried out by morphological examination and molecular phylogenetic analyses inferred from six gene loci including the internal transcribed spacer regions (ITS), the large subunit of nuclear ribosomal RNA gene (nLSU), the second largest subunit of RNA polymerase II gene (rpb2), the translation elongation factor 1-α gene (tef1), the small subunit mitochondrial rRNA gene (mtSSU) and the small subunit nuclear ribosomal RNA gene (nSSU). A total of 1 382 sequences were used in the phylogenetic analyses, of which 817 were newly generated, including 132 sequences of ITS, 139 sequences of nLSU, 83 sequences of rpb2, 124 sequences of tef1, 150 sequences of mtSSU and 189 sequences of nSSU. The combined six-gene dataset included sequences from 391 specimens representing 146 taxa from Ganodermataceae. Based on morphological and phylogenetic analyses, 14 genera were confirmed in Ganodermataceae: Amauroderma, Amaurodermellus, Cristataspora, Foraminispora, Furtadoella, Ganoderma, Haddowia, Humphreya, Magoderna, Neoganoderma, Sanguinoderma, Sinoganoderma, Tomophagus and Trachydermella. Among these genera, Neoganoderma gen. nov. is proposed for Ganoderma neurosporum; Sinoganoderma gen. nov. is proposed for Ganoderma shandongense; Furtadoella gen. nov. is proposed to include taxa previously belonging to Furtadoa since Furtadoa is a homonym of a plant genus in the Araceae; Trachydermella gen. nov. is proposed to include Trachyderma tsunodae since Trachyderma is a homonym of a lichen genus in the Pannariaceae. Twenty-three new species, viz., Ganoderma acaciicola, G. acontextum, G. alpinum, G. bubalinomarginatum, G. castaneum, G. chuxiongense, G. cocoicola, G. fallax, G. guangxiense, G. puerense, G. subangustisporum, G. subellipsoideum, G. subflexipes, G. sublobatum, G. tongshanense, G. yunlingense, Haddowia macropora, Sanguinoderma guangdongense, Sa. infundibulare, Sa. longistipitum, Sa. melanocarpum, Sa. microsporum and Sa. tricolor are described. In addition, another 33 known species are also described in detail for comparison. Scanning electron micrographs of basidiospores of 10 genera in Ganodermataceae are provided. A key to the accepted genera of Ganodermataceae and keys to the accepted species of Ganoderma, Haddowia, Humphreya, Magoderna, Sanguinoderma and Tomophagus are also provided. In total, 278 species are accepted as members of Ganodermataceae including 59 species distributed in China. Taxonomic novelties: New genera: Furtadoella B.K. Cui & Y.F. Sun, Neoganoderma B.K.

Batch Loading in Metadata Creation: A Case Study the Rutgers University Libraries Experience
No full textPurpose – The purpose of this article is to describe a workflow of automated batch loading metadata from existing text to a database.
Methodology/Approach – It introduces a case for the experience of metadata creation at Rutgers University Libraries in a collaborative digital project with the Hoboken Public Library in New Jersey.
Findings – It is found that a well-designed workflow is crucial to the success of metadata batch loading. It is also found that the metadata manager needs to collaborate with people of different roles and work carefully with data reorganization and transferring.
Practical Implications – Metadata creation and management is an integrated component of any digital project. Our experience in metadata batch loading has practical significance that may be incorporated into the practice of other metadata projects. The workflow introduced in this article will provide valuable example for librarians and information professionals to consider or redesign their own digital efforts.
Originality – Based on our real exercise, this workflow has been proven to be unique and useful. It was, after the writing of this article, applied to a new collaborative digital project and once again fulfilled the requirements for another batch transferring process.Peer reviewe
