Digital Preservation Tools for Repository Managers 4: Putting storage, format management and preservation planning in the repository
No full textThe 5-module JISC KeepIt course on Digital Preservation Tools for Repository Managers was designed by repository managers. Each module consists of a mix of short presentations and hands-on exercises to learn about the basics and gain practice with each of the tools covered. Module 4 puts storage, format management and preservation planning in the repository, by making such functions available from within the familiar repository interface. Hitchcock's introduction briefly reviews the previous module, which acted as a primer on preservation workflow, formats and characterisation, as preparation for the preservation planning tools to be encountered in this module. This leads into an extensive practical tutorial on logical and bit-stream preservation using Plato (a preservation planning tool) and EPrints (software for creating digital repositories), which Rauber introduces with a rapid recap on the principles and reasons for digital preservation. Moving on to EPrints, Field presents a new 'hybrid' storage controller for EPrints providing selectable storage options locally and in the cloud. EPrints v3.2 introduces an abstracted storage layer which provides the ability for data hosting services such as Amazon S3 to be used as a storage back-end to EPrints. An accompanying tutorial leads users through some of the storage interfaces that EPrints can use, and also shows how to modify the storage policies. Tarrant places the process of managing formats and risk analysis in the EPrints repository interface. Another supporting exercise gives practical experience with the assignment of risk analysis scores to the discovered file formats to aid in digital preservation decisions. In this activity users are presented with a set of test files, a series of scanned images, for use throughout the remaining exercises. In a major element of this tutorial Rauber and Kulovits review preservation planning workflow, showing how to identify requirements using a mindmap approach and then how to upload the output to Plato, the preservation planning tool, to run experiments and produce results. Two exercises are outlined for users in the final 5 slides of the presentation, to describe the collection of test files provided previously, using the mindmap to define the requirements and to create the plan using Plato. The module completes with an exercise on preservation action (see document, no presentation slides), migrating selected files to new formats as identified in the plan. The preservation plan is uploaded to EPrints to act on the test files, displaying the results in an EPrints interface, also providing the means to review the preservation actions. Materials here include all presentations and supplementary materials to support the practicals, so the full course module can be experienced by other users
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
A Connectionist and Multivariate Approach to Science Maps: Som, Clustering and Mds Applied to Library & Information Science Research.
No full textThe visualization of scientific field structures is a classic of scientometric studies. This paper presents a domain analysis of the library and information science discipline based on author co-citation analysis (ACA) and journal cocitation analysis (JCA). The techniques used for map construction are the self-organizing map (SOM) neural
algorithm, Ward’s clustering method and multidimensional
scaling (MDS). The results of this study are compared with
similar research developed by Howard White and Katherine
McCain [1]. The methodologies used allow us to confirm that
the subject domains identified in this paper are, as well,
present in our study for the corresponding period. The appearance of studies pertaining to library science reveals
the relationship of this realm with information science.
Especially significant is the presence of the management on the journal maps. From a methodological standpoint, meanwhile, we would agree with those authors who consider
MDS, the SOM and clustering as complementary methods
that provide representations of the same reality from different analytical points of view. Even so, the MDS representation is the one offering greater possibilities for the structural representation of the clusters in a set of variables

No full textAuthor, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
