Crystal Structure EPrints: Publication @ Source Through the Open Archive Initiative
No full textRecent advances in crystallographic instrumentation and computational resources have caused an explosion of crystallographic data, as shown by the recent exponential growth of the CSD [1]. However, even this is considered to be lower than expected, following the introduction of area detection. The reason for this is clearly identified as a publication bottleneck, which will become even more severe with developments in high throughput crystallography [2]. As a result of this situation, the user community is deprived of valuable information, and the funding bodies are getting a poor return for their investments!
Electronic publishing has helped to make some inroads into the problem, and is already an integral part of chemical and crystallographic publishing. This has dramatically reduced the turnaround time in the publication process, but the system still fails to keep apace of the generation of structural information, mainly because of the continued reliance on traditional protocols for the assembly of manuscripts and their peer review. The need to maintain some kind of review process is clear, and this makes the sometimes-used direct submission of structures to the CCDC “unpopular”.
Unlike the mathematical and electronic sciences, the chemical sciences have been reluctant to embrace the 'preprint concept' [3]: the one exception has been the efforts of rapid electronic communications journals. This poster outlines a pre-print procedure for the rapid and effective dissemination of structural information to the scientific community which removes the lengthy peer review process that hampers traditional publication routes, but provides an alternative mechanism. Crystallographic EPrints are built on a concept developed in the Computer Science community [4] whereby an author may reveal to the public archives of information. An Eprint makes available all raw, derived and results data from a crystallographic experiment via a searchable and hierarchical system. At the top searchable level this metadata includes bibliographic and chemical identifier items which allow access to a secondary level of searchable crystallographic items which are directly linked to the associated archived data.
Hence the results of a crystal structure determination may be disseminated in a manner that anyone wishing to utilise the information may access the entire archive of data related to it and assess its validity and worth
eCrystallographyDataReports: an open archive route for the reporting and dissemination of crystal structures
No full textAdvances in crystallographic instrumentation and computational resources have caused an explosion of crystallographic data, as shown by the recent exponential growth of the Cambridge Structural Database (CSD) [1]. However, even this is considered to be lower than expected, following the introduction of area detection. The reason for this is clearly identified as a publication bottleneck [2], which can only become even more severe with developments in high throughput crystallography [3].

Unlike the mathematical and electronic sciences, the chemical sciences have been reluctant to embrace the 'preprint concept' [4]: the one exception has been the efforts of rapid electronic communications journals. This poster outlines a publication at source procedure for the rapid and effective dissemination of structural information to the scientific community which removes the lengthy peer review process that hampers traditional publication routes, but provides an alternative mechanism. eCrystallographyDataReports are built on a concept developed in the Computer Science community, the Open Archive Initiative (OAI) [5], whereby an author may reveal to the public archives of information. OAI software, known as ePrints [6], has been modified to implement this new type of open archive. An eCrystallographyDataReport makes available all raw, derived and results data from a crystallographic experiment via a searchable and hierarchical system. At the top searchable level this metadata includes bibliographic and chemical identifier items which allow access to a secondary level of crystallographic items which are directly linked to the associated archived data.
The 'core bibliographic data' is made available to the public domain by the Open Archive Initiative Protocol for Metadata Harvesting (OAI-PMH) [7] so that it may be 'harvested' by data aggregator services. This enables linking of the archive record with other, perhaps not structurally related, published literature. Perhaps more importantly it notifies those monitoring the archive that a new entry is available, hence the CSD may automatically download the structural data and assimilate it into the database. This will return a deposition number which, along with any future literature citations of this entry, can be retrospectively added to the record to link the data or information sources.
eCrystallographyDataReports are intended for the publication of data only. Hence the results of a crystal structure determination may be disseminated in a manner that anyone wishing to utilise the information may access the entire archive of data related to it and assess its validity and worth. The archive entry can then be referenced, which allows learned society journals to streamline articles to contain more intellectual discussion and less experimental reports. This archive software is to be freely available for public download and installation and is simple and inexpensive to set up and maintain
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
