Abstract
The CD-ROM and web versions of the Science Citation Index databases are
compared as to their content and format features. Several differences have
been detected such as the use of different punctuation marks in both
versions and a different organisation of author’s affiliation data. These
differences make automatic comparisons of ISI products difficult and they
should be considered when matching both databases. Some recommendations to
ensure more normalisation and reliability of data are pointed out.

TITLE : The citation impacts and citation environments of Chinese journals

Abstract
Based on the citation data of journals covered by the China Scientific and
Technical Papers and Citations Database (CSTPCD), we obtained aggregated
journal-journal citation environments by applying routines developed
specifically for this purpose. Local citation impact of journals is defined
as the share of the total citations in a local citation environment, which
is expressed as a ratio and can be visualized by the size of the nodes. The
vertical size of the nodes varies proportionally to a journal’s total
citation share, while the horizontal size of the nodes is used to provide
citation information after correction for the within-journal (self-)
citations. In the “citing” environment, the equivalent of the local
citation performance can also be considered as a citation activity index.
Using the “citing” patterns as variables one is able to map how the
relevant journal environments are perceived by the collective of authors of
a journal, while the “cited” environment reflects the impact of journals in
a local environment. In this study, we analyze citation impacts of three
Chinese journals in mathematics and compare local citation impacts with
impact factors. Local citation impacts reflect a journal’s status and
function better than (global) impact factors. We also found that authors in
Chinese journals prefer international instead of domestic ones as sources
for their citations.

TITLE : A bibliometric and citation analysis of stroke-related research in
Taiwan

Abstract
As the population ages in Taiwan, stroke research has received greater
attention in recent years. Strokes have significant impacts on the health
and well-being of the elderly. To formulate future research policy,
information on stroke publications should be collected. In this research,
we studied stroke-related research articles published by Taiwan researchers
which were indexed in the Science Citation Index from 1991 to 2005. We
found that the quantity of publications has increased at a quicker pace
than the worldwide trend. Over the years, there has been an increase in
international collaboration, mainly with researchers in the U.S. Article
visibility, measured as the frequency of being cited, also increased during
the period. It appears that stroke research in Taiwan has become more
globally connected and has also improved in quality. The publication output
was concentrated in a few institutes, but there was a wide variation among
these institutes in the ability to independently conduct research. A wide
array of keywords indicated a probable lack of continuity in research.
Nevertheless, there was an inverse relationship between stroke mortality
and number of published articles in Taiwan. To improve the quality and
efficiency of stroke research, continuity in research focuses needs to be
maintained, and thus funding should be allocated on a long-term basis to
institutes with a proven record of success.

TITLE : Transient and continuant authors in a research field: The case of
terrorism

Abstract
The issue of research continuance in a scientific discipline was analyzed
and applied to the field of terrorism. The growing amount of literature in
this field is produced mostly by one-timers who “visit” the field,
contribute one or two articles, and then move to another subject area. This
research pattern does not contribute to the regularity and constancy of
publication by which a scientific discipline is formed and theories and
paradigms of the field are created. This study observed the research
continuance and transience of scientific publications in terrorism by using
obtainable “most prolific terrorism authors” lists at different points in
time. These lists designed by several terrorism researchers, presented a
few researchers who contributed to the field continuously and many others
whose main research interest lay in another discipline. The four lists
observed included authors who were continuants, transients, new-comers, and
terminators (who left the field). The lack of continuous, full-time
research in a research field is typical of many disciplines, but the
influence of this research pattern on a field’s growth and stability is
different for older, established disciplines than for new and formative
fields of study. With in the former, intellectual mobility could contribute
to the rise of new topics and probably enrich the particular scientific
field; with the latter, by contrast, it could hamper the formation and
growth of the field.

TITLE : An educational resource for information literacy in higher
education: Functional and users analyses of the e-COMS academic portal
AUTHORS : MARIA PINTO, ANNE-VINCIANE DOUCET
Department of Information Science, University of Granada, Granada (Spain)
Abstract
As in today’s knowledge society the Internet is playing an important role
in the information literacy of university students the goal of this paper
is to analyse, after its first year on the Web, the informational impact of
an e-learning resource developed by Granada’s University lecturers (the e-
COMS educational portal), a pioneer in Spain for training in information
literacy. From the objective and subjective data provided by the own portal
and by it users, two different and complementary kinds of analysis
(functional and users’) are performed. Assessment of various capabilities,
among which visibility and usability stand out, is provided. The highly
positive but improvable results offer a detailed analysis of the functional
aspects of the portal itself and of the users’ relations with this
information resource. From these analyses strengths and weaknesses are
extracted and some proposals for improvement are derived.

TITLE : Generalized Hirsch h-index for disclosing latent facts in citation
networks

Abstract
What is the value of a scientist and its impact upon the scientific
thinking? How can we measure the prestige of a journal or a conference? The
evaluation of the scientific work of a scientist and the estimation of the
quality of a journal or conference has long attracted significant interest,
due to the benefits by obtaining an unbiased and fair criterion. Although
it appears to be simple, defining a quality metric is not an easy task. To
overcome the disadvantages of the present metrics used for ranking
scientists and journals, J. E. Hirsch proposed a pioneering metric, the now
famous h-index. In this article we demonstrate several inefficiencies of
this index and develop a pair of generalizations and effective variants of
it to deal with scientist ranking and publication forum ranking. The new
citation indices are able to disclose trendsetters in scientific research,
as well as researchers that constantly shape their field with their
influential work, no matter how old they are. We exhibit the effectiveness
and the benefits of the new indices to unfold the full potential of the h-
index, with extensive experimental results obtained from the DBLP, a widely
known on-line digital library.

TITLE : Separating the articles of authors with the same name
AUTHORS : JOSÉ M. SOLER

Autónoma de Madrid, Madrid (Spain)
Abstract
I describe a method to separate the articles of different authors with the
same name. It is based on a distance between any two publications, defined
in terms of the probability that they would have as many coincidences if
they were drawn at random from all published documents. Articles with a
given author name are then clustered according to their distance, so that
all articles in a cluster belong very likely to the same author. The method
has proven very useful in generating groups of papers that are then
selected manually. This simplifies considerably citation analysis when the
author publication lists are not available.

TITLE : Models for citation behavior
AUTHORS : SARALEES NADARAJAHa SAMUEL KOTZb

bGeorge Washington University, Washington, DC (USA)
Abstract
The number of citations of journal papers is an important measure of the
impact of research. Thus, the modeling of citation behavior needs
attention. Burrell, Egghe, Rousseau and others pioneered this type of
modeling. Several models have been proposed for the citation distribution.
In this note, we derive the most comprehensive collection of formulas for
the citation distribution, covering some 17 flexible families. The
corresponding estimation procedures are also derived by the method of
moments. We feel that this work could serve as a useful reference for the
modeling of citation behavior.

Abstract
The research questions are as follows: to what extent do Canadian medical
school faculty members have person-to-person interactions with individuals
working in public and private sector organizations? What are the
characteristics of Canadian medical school faculty members who interact
with individuals working in these work settings? Are these different
network patterns complementary or substitute? The data used for this study
are from a cross-sectional survey of Canadian medical school faculty
members (n = 907). Structural multivariate ordered probit models were
estimated to explore the characteristics of faculty members with different
network patterns and to see if these network patterns are complementary or
substitute. Study results suggest that the different network patterns
considered in the study are not conflicting, but that some patterns
correspond to different faculty member profiles.

TITLE : Profiling citation impact: A new methodology
AUTHORS : JONATHAN ADAMS, KAREN GURNEY, STUART MARSHALL
Evidence Ltd, Leeds (UK)
Abstract
A methodology for creating bibliometric impact profiles is described. The
advantages of such profiles as a management tool to supplement the
reporting power of traditional average impact metrics are discussed. The
impact profile for the UK as a whole reveals the extent to which the median
and modal UK impact values differ from and are significantly below average
impact. Only one-third of UK output for 1995–2004 is above world average
impact although the UK’s average world-normalised impact is 1.24. Time-
categorised impact profiles are used to test hypotheses about changing
impact and confirm that the increase in average UK impact is due to real
improvement rather than a reduction in low impact outputs. The impact
profile methodology has been applied across disciplines as well as years
and is shown to work well in all subject categories. It reveals substantial
variations in performance between disciplines. The value of calculating the
profile median and mode as well as the average impact are demonstrated.
Finally, the methodology is applied to a specific data-set to compare the
impact profile of the elite Laboratory of Molecular Biology (Cambridge)
with the relevant UK average. This demonstrates an application of the
methodology by identifying where the institute’s exceptional performance is
located. The value of impact profiles lies in their role as an interpretive
aid for non-specialists, not as a technical transformation of the data for
scientometricians.

Abstract
The purpose of the study proposed in this paper is to evaluate the Spanish
public university websites dedicated to the European Higher Education Area
(EHEA). To do so, the quality of these resources has been analysed in the
light of data provided by a series of indicators grouped in seven criteria,
most of which were used to determine what information is made available and
in what way. The criteria used in our analysis are: visibility, authority,
updatedness, accesibility, correctness and completeness, quality assessment
and navigability. All in all, the results allow us to carry out an overall
diagnosis of the situation and also provide us with information about the
situation at each university, thus revealing their main strengths, namely
authority and navegability, and also their chief shortcomings: updatedness,
accessibility and quality assessment. In this way it is possible to detect
the best practices in each of the aspects evaluated so that they can serve
as an example and guide for universities with greater deficiencies and thus
help them to improve their EHEA websites.
