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

Borderplex Economic Growth: Chicken, Egg, or Scrambled?
No full textRegional debates over which metropoitan economy is the dominant growth pole in multi-city areas can be intense. Such discourse is frequently voiced with regard to economic expansion in the El Paso, Texas, USA - Ciudad Juarez, Chihuahua, Mexico borderplex economy. To date, no empirical analyses have been carried out to address that question. Granger causality tests are applied to various cross-border data to shed light on that question and others regarding the nature of regional growth in this international setting.Border economic growth, applied econometrics, population, employment
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Fertility transition in Benin : new reproductive patterns or traditional behaviours?.
No full textThis study analyses reproductive changes in Benin,
a
West African
country with
high fertility
and
low prevalence of use of modem contraceptive methods, using a combination
of quantitative
and
qualitative approaches. Findings indicate that a transition to
lower fertility is
underway, particularly
in the urban areas, as a result of an emerging pattern
of
birth limitation
and continued
desire for the
traditional long birth intervals. But only a
small
change
has
occurred
in the
main proximate
determinants of fertility. The data suggest:
that changes in childhood mortality
in
combination
with
increased
women's
education,
though modest, have probably created
a
demand for fertility
control
among
women;
that induced abortion among other
factors,
may
be
one of the
means through
which
such
demand was met, particularly in urban areas;
and that the economic crisis of the 1980s was the
main catalyst
which precipitated the
onset
of transition.
Changes in reproductive preference and practice suggest
a
diffusion
process,
from the
urban
and
more educated women to the rural and less educated
ones.
The
data
also
reveal that the
low
prevalence of use of modem contraception may
be
associated with
poor
knowledge,
widespread
fear
of side effects and complications and poor quality
of
family
planning
services.
The
main
policy
implication of these results is that an appropriate reproductive
health
programme
is
required
to
address women's needs and reduce the levels of
unwanted
pregnancies and
induced
abortion
which
are likely to be rising rapidly

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
