Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDFWe 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
Contemporary Migration Processes in Russia
Get PDFThis article, abridged from the Russian
original, was published by the Institute
of Socio-Political Studies of the
Russian Academy of Science, Moscow,
in 1993. Irena Orlova, Y. Streltsova and
E. Skvortsova work in the Department
of Sociology of Migration at the Institute.
Dr. Orlova is the Head of the
Department. The article was translated
by A. Benifand and R. Kovaleva, York
University, and edited by R. Brym,
Professor of Sociology, University of
Toronto.
The article examines the contribution
of migration to Russian population
dynamics, inter-regional
migration flows, the growth of regional
and ethnic separatism, human
rights problems associated with migration,
refugee issues, and the "brain
drain" from Russia. It is based on official
demographic statistics and a wide
range of sociological surveys. It focuses
mainly on the period 1990-93
and contains a brief postscript bringing
the analysis up to date.Cet article estune version abrégée d'un

L'article examine l'effet des migrations
sur la dynamique démographique
en Russie, les flux migratoires
interrégionaux, la croissance des mouvements
séparatistes régionaux et ethniques,
les problèmes des droits de la
personne qui sont liés aux migrations,
la situation des réfugiés et les problèmes
résultant de l'émigration des intellectuels
russes. L'analyse est fondée
sur des statistiques démographiques
officielles et plusieurs études sociologiques.
Elle traite surtout de la période
1990-1993. Le postscriptum décrit les

Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
Get PDFThis 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

Investigation on the possibility of increasing the environmental safety and fuel efficiency of vehicles by means of gasoline nano-additive
Get PDFEnvironmental safety problemoriginatedfromvehicles requiresdevelopment andexploration of integrated and effective solutions, which considers the development level of technologies, the cost of their widespread use, the legislation requirements and other relevant aspects. One improvement method of the petroleum-derived fuels characteristics is the use of additives that complement the refining methods and provide ample opportunities to influence the individual characteristics. The aim of this work is to study the influence of the developed multifunctional surface-active nano-additive on the gasoline characteristics and engine performance. The measurement results confirmed the effective reduction of the surface tension of gasoline at the boundary with air, improving the mixture formation in the engine. On the other hand, the saturated vapor pressure was significantly decreased, which dramatically reduces evaporation losses and air pollution by light hydrocarbons. The use of the additive, due to a combination of its surface-active and catalytic action, significantly increases the fuel efficiency of engines and reduces octane requirements, greenhouse gases emissions, as well as noise level during operation of vehicles, and the environmental safety of vehicle operation increases. © 2019 by the authors
Mining e-mail content for author identification forensics
No full textWe describe an investigation into e-mail content mining for author identification, or authorship attribution, for the purpose of forensic investigation. We focus our discussion on the ability to discriminate between authors for the case of both aggregated e-mail topics as well as across different email topics. An extended set of e-mail document features including structural characteristics and linguistic patterns were derived and, together with a Support Vector Machine learning algorithm, were used for mining the e-mail content. Experiments using a number of e-mail documents generated by different authors on a set of topics gave promising results for both aggregated and multi-topic author categorisation
