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
Synthesis and characterisation of phosphinothiolate tin(IV) complexes. Crystal structure of (SnBu2)-Bu-t(OPPh2C6H4S)(OH2) ClO4.H2O
No full text[SnR2Cl2] (R=Me, tBu) react with OPPh2C6H4SH in the presence of NaOEt affording mononuclear derivatives [SnR2(OPPh2C6H4S)2] (1, 2) with two units of the oxide of the thiophenylphosphine. The loss of one of such units is achieved by the reaction of 1 and 2 with HCF3SO3 or HClO4 giving rise to complexes with the formula [SnR2(OPPh2C6H4S)]A (A=CF3SO3, ClO4) (3a–b, 4a–b). The crystal structure of [SntBu2(OPPh2C6H4S)]ClO4 (4b) has been determined by X-ray diffraction
Una mirada no tan cerrada e intransigente
No full textPresentar y glosar la postura respecto a
los diversos tipos de infieles de los teólogos
dominicos del siglo XVI Cardenal Cayetano
y Bartolomé de las Casas, partiendo de santo
Tomás de Aquino. El Obispo misionero
escribirá que esta distinción es muy necesaria
para el estudio y trato con los infieles. Pero es que además, fue una mirada “no tan
cerrada” e intransigente –más ecuménica,
diríamos hoy– en los que la siguieron, que
desafortunadamente no fueron muchos
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
