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
Thermopower Of An Intermediate Valence Model Of Tl2mn 2o7
No full textIn this work we calculate the thermopower of Tl2Mn 2O7, together with its static resistivity and dynamical conductivity. This compound exhibits colossal magnetoresistance, which is not adequately explained by the double-exchange mechanism. We use Hubbard operators to reformulate a previous model of Ventura and Alascio that describes the 3d orbitals of Mn with two magnetic configurations, hybridized with a conduction band associated to the Tl. We reformulate a previous treatment to obtain approximate one-electron green's functions (GF) for the model. We have employed these GF to calculate the properties mentioned above for several values of the system parameters and obtained a qualitative agreement with the experimental results. © 2004 Elsevier B.V.

No full textThe reading The Concept of Equity. An Interdisciplinary Assesment (Universitätsverlag
Winter, Heidelberg, 2007), edited by Daniela Carpi, is a good exemple of Law and literature
approach. In the three sections of this paper, however, three qualifications to such
approach are produced: a) literary criticism and legal theory do remain different matters;
b) legal theory, and legal history too, have to distinguish external from internal equity,
which are branches of morals and law respectively; 3) a different story of equity is possible:
not good equity vs. bad law, but just the opposite
