Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Review of the micro-tubular solid oxide fuel cell
No full textFuel cells are devices that convert chemical energy in hydrogen enriched fuels into electricity electrochemically.
Micro-tubular solid oxide fuel cells (MT-SOFCs), the type pioneered by K. Kendall in the early
1990s, are a variety of SOFCs that are on the scale of millimetres compared to their much larger SOFC
relatives that are typically on the scale of tens of centimetres. The main advantage of the MT-SOFC, over
its larger predecessor, is that it is smaller in size and is more suitable for rapid start up. This may allowthe
SOFC to be used in devices such as auxiliary power units, automotive power supplies, mobile electricity
generators and battery re-chargers.
The following paper is Part I of a two part series. Part I will introduce the reader to the MT-SOFC
stack and its applications, indicating who is researching what in this field and also specifically investigate
the design issues related to multi-cell reactor systems called stacks. Part II will review in detail the
combinations of materials and methods used to produce the electrodes and electrolytes of MT-SOFC’s.
Also the role of modelling and validation techniques used in the design and improvement of the electrodes
and electrolytes will be investigated. A broad range of scientific and engineering disciplines are
involved in a stack design. Scientific and engineering content has been discussed in the areas of thermalself-
sustainability and efficiency, sealing technologies, manifold design, electrical connections and cell
performance optimisation
