Carl Friedrich Geiser and Ferdinand Rudio : the men behind the first International Congress of Mathematicians
No full textThe first International Congress of Mathematicians (ICM) was held in Zurich in 1897, setting the standards for all future ICMs. Whilst giving an overview of the congress itself, this thesis focuses on the Swiss organisers, who were predominantly university professors and secondary school teachers. As this thesis aims to offer some insight into their lives, it includes their biographies, highlighting their individual contributions to the congress. Furthermore, it explains why Zurich was chosen as the first host city and how the committee proceeded with the congress organisation.
Two of the main organisers were the Swiss geometers Carl Friedrich Geiser (1843-1934) and Ferdinand Rudio (1856-1929). In addition to the congress, they also made valuable contributions to mathematical education, and in Rudio’s case, the history of mathematics. Therefore, this thesis focuses primarily on these two mathematicians.
As for Geiser, the relationship to his great-uncle Jakob Steiner is explained in more detail. Furthermore, his contributions to the administration of the Swiss Federal Institute of Technology are summarised. Due to the overarching theme of mathematical education and collaborations in this thesis, Geiser’s schoolbook "Einleitung in die synthetische Geometrie" is considered in more detail and Geiser’s methods are highlighted.
A selection of Rudio’s contributions to the history of mathematics is studied as well. His book "Archimedes, Huygens, Lambert, Legendre" is analysed and compared to E W Hobson’s treatise "Squaring the Circle". Furthermore, Rudio’s papers relating to the commentary of Simplicius on quadratures by Antiphon and Hippocrates are considered, focusing on Rudio’s translation of the commentary and on "Die Möndchen des Hippokrates". The thesis concludes with an analysis of Rudio’s popular lectures "Leonhard Euler" and "Über den Antheil der mathematischen Wissenschaften an der Kultur der Renaissance", which are prime examples of his approach to the history of mathematics

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Antennae brown from the 3 rd joint onwards. Elytra dark brown, with a large testaceous patch around shoulder, the suture and the margin narrowly so on the whole length. Underside completely testaceous, abdomen testaceous-brown. Head: Large, testaceous; transverse, distance from eye to pronotum equal to 1.5 times diameter of an eye. Interocular space large, 2.8 times as large as eye diameter. Anterior margin of frons almost evenly curved concavely; head strongly depressed on antero-median part. Surface shining, covered with fine punctures and very fine and long yellow setae. Mandibles long, slender, straight, only slightly curved. Last segment of maxillary and labial palpi broad, 3.7 times as long as broad, flattened and strongly elongate, about 1 / 3 longer than mandibles, with fine pubescence; setae dense, fine and testaceous. Apex of last joint of maxillary palpi broadly rounded, labial palpi narrowly so. Antennae long, filiform, 1 st, 3 rd and 4 th joints elongate, 2 nd joint very small, globulose, 5 th - 11 th joints subequal, cylindrical, about 2.2 times as long as broad. Pronotum: Testaceous, slightly transverse, strongly and deeply depressed posteriorly before angles. Anterior margin rounded. Posterior angles protruding and obliquely carinate. Entire surface shining with small punctures, each with a long and very fine yellow seta. Scutellum broad, triangular and testaceous. Elytra: Dark brown, testaceous on base around shoulders and narrowly so along suture and along margin on the whole length. Sides slightly dilated, almost parallel, broadest behind middle, with 3 distinct costae and coarsely punctured. Punctures very large, individually visible, deeply impressed and much closer together than their own diameter. Pubescence dense; setae short, very fine and brown. Elytral margins narrowly bordered. Underside: Completely testaceous, finely and densely pubescent. Aedeagus: Lateral lobes narrow, rounded and with a few setae posteriorly, ending a sharp point dorsally. Median lobe with a sharp ridge dorsally. Female: Unknown. Measurements: TL: 8.6–8.7 mm; TL-H: 7.1 mm; HL: 2.0 mm; HW: 2.25 mm; LP: 1.9 Type material: Holotype 3 (NHMB): “NE India, Meghalaya, Tura Peak, 600–1000 m, 25 ° 31 ’N 90 ° 14 ’E, Pacholátko leg, 12–22.VI. 2007 ” [white printed label]. “ Holotype Lamellipalpus pacholatkoi turaensis n.ssp. Brancucci & Geiser 08” [red printed label]. Paratype: 1 specimen with same data as holotype (NHMB). This specimen has a red printed paratype label. Etymology: The name of this species is derived from the type locality, Tura Peak, Meghalaya. Affinities: We decided to rank the specimens from Tura Peak as a subspecies as they are distinct from the typical specimens, particularly in their size. Otherwise the characters are not sufficient to rank these specimens as a distinct species. The most closely related species is L. kubani sp. nov. from Thailand. However, in the present subspecies the joints of the antennae are much more elongate (globulose in L. kubani sp. nov.), and the punctures on the elytra are evenly distributed and not confluent, with each one distinctly visible. Distribution: NE India (Meghalaya).Published as part of Brancucci, Michel & Geiser, Michael, 2009, A revision of the genus Lamellipalpus Maulik, 1921 (Coleoptera, Lampyridae), pp. 1-20 in Zootaxa 2080 on page 10, DOI: 10.5281/zenodo.18733
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
