TITLE: Can Otolaryngology Compete with Larger Fields Regarding
Impact Factor? Is Percentile-Based Impact Factor a Solution? (Editorial
Material, English)
AUTHOR: Labadie, RF; Fitzpatrick, JM
SOURCE: OTOLARYNGOLOGY-HEAD AND NECK SURGERY 145 (1). JUL 2011.
p.15-17 SAGE PUBLICATIONS LTD, LONDON
KEYWORDS: impact factor; surgical specialty fields
KEYWORDS+: DOCUMENTATION
ABSTRACT: Impact factor (IF) consists of reporting the number of
references an average article in a given journal receives over a 2-year
period. Despite several valid criticisms, IF has become an important
component of academic advancement. The authors sought to investigate the
possible relationship between size of specialty field and IF. The top 10
journals of 13 specialty fields were selected based on IF as reported by
Journal Citations Reports on the Web of Science. Specialty field
population was obtained from the American Board of Medical Specialties. A
highly positive correlation (r = 0.9) was noted with smaller fields (eg,
otolaryngology) having lower IFs. To overcome this population bias, a
percentile-based impact factor (PIF) may be used where the top journal
within a field is given 100%, the worst 0%, and all other journals' IFs
are proportionately scaled in between the 2 extremes. PIF acts to "level
the playing field," allowing between-specialty field comparisons.

TITLE: The visibility of health web portals for teens: a
hyperlink analysis (Article, English)
AUTHOR: Bowler, L; Hong, WY; He, DQ
SOURCE: ONLINE INFORMATION REVIEW 35 (3). 2011. p.443-470
EMERALD GROUP PUBLISHING LIMITED, BINGLEY
KEYWORDS: Adolescents; Health information; Web portals; Visibility;
Hyperlinks; Webometrics; Web sites; Portals
KEYWORDS+: HIGH-SCHOOL-STUDENTS; WORLD-WIDE-WEB; INFORMATION-SEEKING;
SEARCH ENGINES; IMPACT FACTORS; ADOLESCENTS; INTERNET;
SCIENCE; SITES; WEBOMETRICS
ABSTRACT: Purpose - The purpose of this study was to analyse the
hyperlinks leading to six teen health websites in order to assess the
visibility of teen health web portals as well as to discover which
websites refer teens to reliable health information.
Design/methodology/approach - An environmental scan of the web was
conducted to find sample health websites for teens. Inlink data was
gathered using Google Webmaster Tools, and the inlink sources were
classified by the type of creator.
Findings - The teen health websites in this study had a low level of
visibility on the web compared to general health web portals (such as
Medline Plus, for example) and a weak level of referrals from health-
related groups compared to other organisations such as schools and public
libraries. Many non-healthcare related websites are linking to teen
health information, demonstrating that teens' health information needs
are being met by sources that lack expertise in health care.
Research limitations/implications - Due to the small sample of six
websites, generalisations beyond the context of the study are difficult
to infer. The Google Webmaster inlink tool does not guarantee 100 per
cent coverage and some inlinks may not have been captured by the tool,
although this number is most likely minimal. The results of this study
present a snapshot rather than an all-inclusive view of the visibility of
teen health websites and offer a starting point for further investigation.
Practical implications - The weak network of inlinks leading from
reliable health care providers is a lost opportunity for health care
professionals to reach young people.
Social implications - Due to the weak network of inlinks from reliable
health information sources, teens may not be accessing accurate and
reliable health information. This could have a potential cost in terms of
health outcomes.
Originality/value - The study investigates health information for teens,
a population that increasingly uses the web as a source for health
information. The authors used an approach that has not been used before
in the study of teens and health information on the web.

TITLE: Concentration effect of citation to Iranian papers:
Iran's Matthew core journals (Article, English)

ABSTRACT: Purpose - The purpose of this study is to attempt to
suggest an adjustment in Iran's national publication strategy based on
the country-specific Matthew core journals. It investigates Iran's
performance in its national journal set, and proposes a more prominent
journal subset.
Design/methodology/approach - A citation analysis method is applied to
study Iran's scientific performance in its national journal set. The data
were extracted from the Science Citation Index at Web of Science and JCR
and imported to SPSS for further refinement and analysis.
Findings - The results showed that Iran experienced comparatively
considerable citation loss. Surplus citations are concentrated in a small
number of journals, presented as Iran's positive Matthew core journals.
The results also confirm a relatively poor publication strategy adopted
by Iranian scientists and that a publication concentration does not
necessarily enhance the chance of being widely cited.
Research limitations/implications - These findings imply that Iran needs
to watch more vigilantly the functioning of its science system. To
improve its presence at the international level, Iran should re-orient
its publication strategy towards a more prominent one. This may be the
case for similar science systems, where the emphasis is given to quantity
rather than quality.
Originality/value - Country-specific Matthew core journals, with serious
citation competition, can serve as an important criterion to monitor the
functioning of science systems regarding publication strategy. This is
the first empirical study to employ the concept to suggest improvements
in a country's publication strategy.

TITLE: The h-index, h-core citation rate and the bibliometric
profile of the Scopus database (Article, English)

ABSTRACT: Purpose The h-index has been used to evaluate research
productivity and impact (as manifested by the number of publications and
the number of citations received) at many levels of aggregations for
various targets. The purpose of this paper is to examine the bibliometric
characteristics of the largest multidisciplinary databases that are the
most widely used for measuring research productivity and impact.
Design/methodology/approach - The paper presents preliminary findings
about the Scopus database. It is to be complemented and contrasted by the
bibliometric profile of the Web of Science (WoS) database.
Findings - The test results showed that 18.7 million Scopus records had
one or more cited references, representing 42 per cent of the entire
database content. The ratio of cited reference enhanced records kept
slightly increasing year by year from 1996 to 2009. Scopus classifies the
journals and other serial sources into 27 broad subject areas by
assigning its journals to 21 science disciplines, four social science
disciplines, a single Arts and Humanities category, and/or a
multidisciplinary category. The distribution of records among the broad
subject areas can be searched in Scopus using the four-character codes of
the subject areas. A journal or a single primary document may be assigned
to more than one subject area. However, Scopus overdoes this, and it
significantly distorts the h-index for the broad subject areas. The h-
index of the pre-1996 subset of records for the 21,066,019 documents
published before 1996 is 1,451, i.e. there are records for 1,451
documents in that subset that were cited more than 1,450 times. The total
number of citations received by these 1,451 papers (i.e. the h-core,
representing the number of items that contribute to the h-index) is
4,416,488, producing an average citation rate of 3,044 citations per item
in the h-core of the pre-1996 subset of the entire Scopus database. For
the subset providing records for 23,455,354 documents published after
1995, the h-index is 1,339, so the total number of citations must be at
least 1,792,921. In reality the total number of citations received by
these papers is 3,903,157, yielding a citation rate of 2,915 citations
per document in the h-core. For the entire Scopus database of 44.5
million records the h-index is 1,757.
Originality/value - Knowing the bibliometric features of databases, their
own h-index and related metrics versus those of the alternative tools can
be very useful for computing a variety of research performance
indicators. However, we need to learn much more about our tools in our
rush to metricise everything before we can rest assured that our gauges
gauge correctly or at least with transparent limitations. Learning the
bibliometric profile of the tools used to measure the research
performance of researchers, departments, universities and journals can
help in making better informed decisions, and discovering the limitations
of the measuring tools.
