Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Carl Anderson´s 1932 upward going positron
The 1932 discovery-photo of the positron track in Carl Anderson´s cloud chamber has been shown in numerous books and articles over the years. The 63 MeV positron strangely went upwards in the chamber, a fact not much discussed over the years. In his 1961 article about the early work on the positron and muon[1] Anderson writes:”Curiously enough, despite the strong admonitions of Dr. Millikan that upward-moving cosmic-ray particles were rare, this indeed was an example of one of those very rare upward-moving cosmic ray particles.” However, no explanation about the origin of the upward going positron has been published. In this work we discuss different positron sources and give a detailed explanation of the likely origin of Anderson´s upward going positron.</p
