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
Canvas Supports in Paintings by Nicolai Abildgaard: Fabrics and Formats
No full textAn investigation of the technique and materials in paintings by the Danish artist Nicolai Abildgaard (1743 – 1809) included examination of the canvas supports in a large number of his works. Thread count and weave density were studied by automated weave-mapping computer software, designed for working with digital X-radiographs. This was also used for the comparison of weave patterns in order to establish matches between the canvases of various paintings and thereby verify that different canvases originated from the same bolt.The canvas supports in paintings executed by Abildgaard in Rome 1772-77 appeared to be typical only in some ways for Italian canvas production of the era. In comparison, the supports of his Danish paintings were found to have features in common that to a large degree were determined by practical and economic factors such as Danish eighteenth-century fiscal policy, market conditions and manufacture circumstances. This applied to the quality of the fabric, i.e. the type of fibre, thread count and tightness of weave, as well as the scale and the formats within which the majority of the paintings fall.<br/
An Early Work by Titian: The 'Portrait of a Man' in Copenhagen
No full textTizians mandsportræt i København har været genstand for kun ringe grad af opmærksomhed i forskningen til trods for, at det giver et fascinerende indblik i kunstnerens tidligere karriere som portrætmaler. Artiklen forsøger at afhjælpe dette ved dels at redegøre for resultaterne af en nylig maleteknisk undersøgelse og dels at inddrage ny viden relateret til Tizians tidlige produktion. Portrættets undertiden betvivlede tilskrivning, dateringen og betydningen for den tidlige del af Tizians oeuvre diskuteres, såvel som muligheden for at portrættet forestiller Tizians aldrende læremester Giovanni Bellini
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

No full textFarveændringer er et fænomen der ses med jævne mellemrum i malerier fra den danske Guldalder, dvs perioden ca 1810-1850. En udvikling i produktionen og salget af kunstnerfarver samt opfindelsen af nye farver allerede fra fra de tidlige år af århundredet betød, at malerne havde et bredere udvalg til rådighed, men heriblandt også produkter, som havde ringere holdbarhed og lysægthed end forudset. Kunstnernes skoling i perioden havde en karakter, som kun i ringe grad rustede dem til at imødegå de materialemæssige udfordringer, som udviklingen medførte. De affødte farveændringer har i flere tilfælde medført en ændret opfattelse, og undertiden en fejltolkning, af motiverne
