Lichenological Contributions in Honour of David Galloway
No full textDavid Galloway, former president of the IAL, became 65 in May 2007. On this occasion 55 colleagues and friends contributed a Festschrift with 36 papers. The editors took the chance to invite papers in two major fields of interest of the jubilee; the history of lichenology and southern hemisphere and tropical lichenology. The historical part of the volume comprises 7 papers on 118 pages including A bibliography of David Galloway (L. Arvidsson). Special contributions are devoted to Eric Acharius (I. Kärnefelt & A. Thell), William Lauder Lindsay (D. L. Hawksworth) and Richard Spruce (M. R. D. Seaward) or to broader topics like the history of lichenology in Norway (P. M. Jørgensen), the early years of the International Association for Lichenology (I. Kärnefelt & A. Thell) and the history of the Uppsala lichen herbarium (R. Moberg: What a visitor’s book reveals). The major part with nearly 500 pages presents a wide range of taxonomic or floristic novelties from the Southern Hemisphere but also 4 papers on lichen ecology. 13 species are named in honour of David Galloway in the present volume. They are listed on page 28 at the end of the bibliography; but unfortunately there is no list of the many other taxonomic novelties and changes introduced in the volume. Three new genera are proposed: Catillochroma Kalb in the Megalariaceae, Davidgallowaya Aptroot in the Parmeliaceae s.l. and Gallaicolichen Sérusiaux & Lücking. Taxonomic changes (mostly new taxa) are presented in the following genera: Anzia, Bacidia, Bilimbia, Caloplaca, Candelaria, Carbonea, Chiodecton, Cladonia, Coccocarpia, Coenogonium, Cryptolechia, Dactylospora, Haematomma, Himantormia, Hypotrachyna, Leptogium, Megalaria, Menegazzia, Parmelia, Parmeliopsis, Parmotrema, Punctelia, Ramalina, Relicina, Rimularia, Roccella, Sphaerellothecium, Teloschistes, Tephromela, Thelotrema and Trapelia. There is also a number of keys included in various papers: cetrarioid lichens in the southern hemisphere (T. Randlane & A. Saag), Coccocarpia in Costa Rica (R. Lücking et al.), Cryptolechia all species (K. Kalb), Ramalina osorioi group in South America (H. Kashiwadani et al.) and Teloschistes in Africa (P. Frödén & I. Kärnefelt). To highlight the variety of topics the 2 most extended papers might be mentioned. In a paper entitled New species of the genus Caloplaca in Australia (S. Ya. Kodratyul et al.) no less than 19 new species are described. Under the title A contribution to the knowledge of lichenicolous fungi and lichens occurring in New Zealand (J. Hafellner & H. Mayrhofer) data on 60 taxa are presented of which 28 represent new country records. Limited space does not allow to mention more single contributions. The editors Ingvar and Arne did an impressive job by organizing and editing such a huge and important volume but nevertheless a few shortcommings must be mentioned: on page 43 and 47 a paragraph of 14 lines is printed twice and on page 43 in the second line the word "clerynen" appears which should be read as "clergymen". Few photograph illustrations are of lower quality because of the use of scanned copies instead of the original photographs (e.g. p. 57)

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
