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
ORIGIN OF THE RAW MATERIAL OF THE SCULPTURES AND COLUMNS FROM STRZELNO IN THE COLLECTIONS OF THE NATIONAL MUSEUM IN POZNAN IN THE LIGHT OF PETROGRAPHIC RESEARCH
No full textThe research note discusses the outcome of petrographic studies relating to five Romanesque stone monuments from Strzelno, featured at the National Museum in Poznan. The research encompassed:
- a perpendicular fragment of a column shaft 50 x 24 cm (dep. 64), originating from the post-Premonstratensian church of the Holy Trinity in Strzelno, covered with an ornamental tendril;
- a fragment of the shaft of a column with an angel 28 x 28 x 28 cm (dep. 564) from the church of the Holy Trinity;
- the head of Christ from the foundation tympanum in the rotunda of St. Prokop, damaged in a fire from 1945 (P. 19);
- the head of a statue 22 x 20 x 21 cm (dep. 563), unearthed in the course of archaeological excavations in front of the rotunda of St. Prokop in 1950;
- a column capital 40 x 36 x 20 cm (dep. 65) from the church of the Holy Trinity, with acanthus leafs in the corners and a fragment of a lamb.
The examined monuments disclosed the presence of two types of sandstone: white quartzose sandstone, used for making the shaft of the column covered with an ornamental tendril, the shaft of a column with an angle, and the head of Christ, as well as subarkose sandstone used for the head of the statue and the column with acanthus leafs.
It is difficult to propose an unambiguous origin of the white sandstone which could have been mined in the Warta river valley, e. g. near Konin-Brzezno (Tertiary sandstone), or in the Sudety Mts. in the regions of Zlotoryja, Lwowek Slaski, and Boleslawiec, as well as in Klodzko - between Polanica, Radkow and Krzeszowice (Cretaceous sandstone).
The mineral composition of the red sandstones, their colour, and the presence of a calcite-clayey cement indicate a resemblance to the Permian period (Rotliegend) or Triassic sandstone (Buntsandstein) which do not occur in the Polish lowlands, and whose nearest outcroppings are located in the Sudety Mts. Particular attention is drawn to the petrographic similarity of this raw material to the sandstone in the portal of the abbey in Olbin, inserted into the southern nave of the church of St. Mary Magdalene in Wroclaw.
The establishment of a connection between those monuments was rendered possible by a petrographic expert study of the abbey portal sandstone conducted by Alfred Majerowicz in 1963. The description contained therein corresponds to the petrography of the red sandstones from Strzelno. This similarity cannot be regarded as accidental since the raw material in question is not universally available. A sculptor could have used a similarly coloured raw material but he was unable to perceive the forms of the microscopic kaolinite crystals and the carbonates between the quartz grains. Consequently, we may conclude that the sandstone was brought over to Strzelno (in a raw form or as a completed work) probably by the same stone-cutters who made the portal for Olbin Abbey
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
