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
Model regionalnej biblioteki cyfrowej na przykładzie Śląskiej Biblioteki Cyfrowej
Get PDFThe dissertation presents a model-template of a regional digital library (RDL) built with the use of
a diagnostic and functional approach to modelling an organisation. The model takes into account the
communicative nature of the RDL and is constructed following recommendations of the
international standards for long-term information preservation and sharing systems – OAIS and
PAIS.
The characteristics of RDL includes definitions, typologies and models of digital libraries (DL) and
is illustrated with the discussion of projects involving digitisation of cultural heritage in Poland and
worldwide. It includes examples of projects and DL, the beginnings of national, regional digital
librarianship, 9 European and American projects of DLs of a regional nature, and a comparative
analysis of 10 Polish RDLs.
To identify the conditions of functioning of the RDL, the properties of digital media, the postulates
of the economy of using information, the dynamics of technical progress in IT and new virtualised
forms of organisation have been analysed. These issues were supplemented with issues related to
librarianship: regional librarianship, copyright, automation of library processes and information
architecture in DL.
The diagnostic stage of modelling covered the case study of the Silesian Digital Library, currently
the largest RDL in Poland. At the functional stage, the RDL functions have analysed: resource
acquisition/condensation, giving context, long-term preservation and filtering access to the
resource.
In the presented model, the RDL structure is a set of geographically dispersed, cooperating entities
(Actors), performing tasks (Roles) in digitisation processes – from gaining access to original
documents, to presenting them on the RDL Access Platform. One Actor can play many Roles.
External Actors (e.g. external companies and institutions), not formally related to RDL, were also
distinguished. These can contribute to its resource, as long as they provide agreed data packages.
The functioning of RDL is process-based – RDL Actors carry out sequences of actions which are
appropriate to their roles: Owner, Supplier, Producer, Archive and Access Platform / Resource
Filter. RDL processes correspond to properly interpreted, traditional library processes: acquisition, cataloguing, preservation (archiving) and making available of documents. They are implemented in
a strictly defined RDL information architecture, which defines information packages resulting from
the processes.
The developed RDL model combines the organisational structure (Actors and their Roles), the
sequence of processes and the information architecture of the entire organisation. The structure of
the model is descriptively supplemented with organisational units supporting the acquisition
of documents in the region, regulation of copyright issues, support of competence development of
RDL Actors and information about resources, preparation of projects and promotion.
This model opens up a futuristic perspective in which RDL is an organisation that exists online and
is accessible online. The future RDL, thanks to a strictly defined information architecture,
separation of Actors from their Roles, recognition of External Actors as its co-creators, can be freely
migrated in the Archive and Platform for access to other places and entities in the network, offering
e.g. more favourable infrastructure or cost conditions. The physical ‘location’ of RDL Producers,
which are already companies from other parts of the country, is also not important.
The assumptions of OAIS and the RDL architecture determined by this standard make its ‘core’
independent of its physical location. RDL can be thought of as a complex digital object and sent
over networks to other physical locations. Advances in hardware and software mean that these
resources are no longer critical for organising and physically locating components of the RDL,
while maintaining control over its process chain and data structures
