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
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
B decays as spectroscope for charmed four-quark states
No full textAbstractThe Ds(2320) state recently observed by BaBar in the Ds+π0 channel may be the first of a host of cqq̄q̄ four-quark states. We give a phenomenological account of the masses and decay modes. The isosinglet Ds(2320) state is the only narrow one, dominated by the observed isospin violating decay and less than ∼ 100 keV in width. All other states are expected to decay hadronically. Notable resonances are in doubly charged Ds+π+, D+K+, wrong pairing D+K−, and also Ds+K−, Dη channels. We propose B decays as searching ground for such 4-quark states, which recoil against D̄(∗) meson from B decay, or π+ D̄(∗), K̄ mesons from B̄ decay. Exotic qcc̄q̄ charmonia could also be produced, and may be behind the slow J/ψ bump in inclusive B→J/ψ+X decay
