Draft Bibliometric Analysis
for the U.S. Environmental Protection Agency/Office of Research
and Development's Fellowship Program (Fellowships Awarded in
1995 and 1996 Only)
This is a bibliometric analysis of the papers authored by the 244 individuals who received a
Science To Achieve Results (STAR) or Greater Research Opportunity (GRO) Fellowship in
1995 or 1996 from the U.S. Environmental Protection Agency (EPA). For this analysis, 1,257
papers were reviewed, and they were published from 1996 to 2006. These publications were
cited 16,280 times in the journals covered by Thomson's Web of Science1 and Scopus2. Of
these 1,257 publications, 1,019 (81.07%) have been cited at least once in a journal.
Searches of Thomson Scientific's Web of Science and Scopus were conducted to obtain times
cited data for the fellows' journal publications. The analysis was completed using Thomson's
Essential Science Indicators (ESI) and Journal Citation Reports (JCR) as benchmarks. ESI
provides access to a unique and comprehensive compilation of essential science performance
statistics and science trends data derived from Thomson's databases. For this analysis, the ESI
highly cited papers thresholds as well as the hot papers thresholds were used to assess the
influence and impact of the fellows' papers. JCR is a recognized authority for evaluating
journals. It presents quantifiable statistical data that provide a systematic, objective way to
evaluate the world's leading journals and their impact and influence in the global research
community. The two key measures used in this analysis to assess the journals in which the
EPA fellows' papers are published are the Impact Factor and Immediacy Index. The Impact
Factor is a measure of the frequency with which the "average article" in a journal has been
cited in a particular year. The Impact Factor helps evaluate a journal's relative importance,
especially when compared to other journals in the same field. The Immediacy Index is a
measure of how quickly the "average article" in a journal is cited. This index indicates how
often articles published in a journal are cited within the same year and it is useful in comparing
how quickly journals are cited.
The report includes a summary of the results of the analysis, an analysis of the 1,257 fellows'
papers analyzed by ESI field (e.g., chemistry, environment/ecology, engineering), an analysis
of the journals in which the fellows' papers were published, a table of the highly cited
researchers who were in the fellowship program, and a list of the patents and patent
applications for the former fellows.
Thomson Scientific's Web of Science provides access to current and retrospective multidisciplinary information
from approximately 8,830 of the most prestigious, high impact research journals in the world. Web of Science also
provides cited reference searching.

Scopus is a large abstract and citation database of research literature and quality Web sources designed to support
the literature research process. Scopus offers access to 15,000 titles from 4,000 different publishers, more than
12,850 academic journals (including coverage of 535 Open Access journals, 750 conference proceedings, and 600
trade publications), 27 million abstracts, 245 million references, 200 million scientific Web pages, and 13 million
patent records.

Bibliometric Analysis of 1995-1996 EPA Fellows' Journal Articles
SUMMARY OF RESULTS
l. More than one-sixth of the fellows' publications are highly cited papers. A review of the
citations indicates that 217 (17.26%) of the fellows' papers qualify as highly cited when using the
ES/ criteria for the top 10% of highly cited publications. This is 1.7 times the number expected.
Thirty-one (2.47%) of the fellows' papers qualify as highly cited when using the ES/ criteria for
the top 1%, which is 2.5 times the number expected. Seven (0.56%) of these papers qualify as
very highly cited when using the criteria for the top 0.1%, which is 5.6 times the number
anticipated. None of the papers actually meet the 0.01 % threshold for the most highly cited
papers, which is not surprising given that the expected number of papers that would meet this
threshold for this analysis is 0.12.
2. The fellows' papers are more highly cited than the average paper. Using the ESI average
citation rates for papers published by field as the benchmark, in 15 of the 22 fields in which the
EPA fellows' papers were published, the ratio of actual to expected cites is greater than 1,
indicating that the fellows' papers are more highly cited than the average papers in those fields.
For all 22 fields combined, the ratio of total number of cites to the total number of expected cites
(16,280 to 10,479.32) is 1.55, indicating that the fellows' papers are more highly cited than the
average paper.
3. One-third of the fellows' papers are published in high impact journals. Four hundred
seventy-seven (477) of the 1,257 papers were published in the top 10% of journals ranked by
JCF? Impact Factor, representing 37.95% of EPA fellows' papers. This number is 3.8 times
higher than expected. Four hundred nineteen (419) of the 1,257 papers appear in the top 10% of
journals ranked by JCf? Immediacy Index, representing 33.33% of EPA fellows' papers. This
number is 3.3 times higher than expected.
4. Twenty of the fellows' papers qualify as hot papers. Using the hot paper thresholds
established by ESI as a benchmark, 20 hot papers, representing 1.59% of the fellows' papers,
were identified in the analysis. Hot papers are papers that were highly cited shortly after they
were published. The number of fellows' hot papers is 16 times higher than the 1.26 hot papers
expected.
5. The authors of the fellows' papers cite themselves much less than the average author.
Eight hundred forty-four (844) of the 16,280 cites are author self-cites. This 5.18% author self-
citation rate is well below the accepted range of 10-30% author self-citation rate.
6. None of the fellows are included in ISIHighlyCited.com, which is a database of the world's
most influential researchers who have made key contributions to science and technology during
the period from 1981 to 1999. This result is not surprising given that the 1995-1996 fellows
probably began their careers in the late 1990s.
7. There were 13 patents issued and 31 patent applications filed by 1995-1996 EPA fellows.
Ten (76.90%) of the 13 patents have been referenced by 22 other patents.

Bibliometric Analysis of 1995-1996 EPA Fellows' Journal Articles
Highly Cited Fellows' Publications
All of the journals covered by ESI are assigned a field, and to compensate for varying citation rates
across scientific fields, different thresholds are applied to each field. Thresholds are set to select
highly cited papers to be listed in ESI. Different thresholds are set for both field and year of
publication. Setting different thresholds for each year allows comparable representation for older and
younger papers for each field.
The 1,257 fellows' research papers reviewed for this analysis were published in journals that were
assigned to 22 of the 22 ESI fields. The distribution of the papers among these 22 fields and the
number of citations by field are presented in Table 1.

Thirty-one (2.47%) of the papers analyzed qualify as highly cited when using the ESI criteria for the
top 1% of papers. These papers cover nine fields—Agricultural Sciences, Biology & Biochemistry,
Chemistry, Clinical Medicine, Engineering, Environment/Ecology, Geosciences, Multidisciplinary,
and Plant & Animal Science. Table 3 shows the 31 papers by field that meet the top 1% threshold in
ESI The citations for these 31 papers are provided in Tables 4 through 12. There were 7 (0.56%)
very highly cited fellows' papers in the fields of Environment/Ecology, Multidisciplinary, and Plant &
Animal Science. These papers, which meet the top 0.1% threshold in ESI, are listed in Table 13.
None of the fellows' papers actually meets the top 0.01% threshold in ESI, which is not surprising
given that the expected number of papers to meet this threshold for this analysis is 0.12.

Bibliometric Analysis of 1995-1996 EPA Fellows' Journal Articles
Ratio of Actual Cites to Expected Citation Rates
The expected citation rate is the average number of cites that a paper published in the same journal in
the same year and of the same document type (article, review, editorial, etc.) has received from the
year of publication to the present. Using the ESI average citation rates for papers published by field as
the benchmark, in 15 of the 22 fields in which the EPA fellows' papers were published, the ratio of
actual to expected cites is greater than 1, indicating that the fellows' papers are more highly cited than
the average papers in those fields (see Table 14). For all 22 fields combined, the ratio of total number
of cites to the total number of expected cites (16,280 to 10,479.32) is 1.55, indicating that the fellows'
papers are more highly cited than the average paper.

JCR Benchmarks
Impact Factor. The JCR Impact Factor is a well known metric in citation analysis. It is a measure of
the frequency with which the "average article" in a journal has been cited in a particular year. The
Impact Factor helps evaluate a journal's relative importance, especially when compared to others in the
same field. The Impact Factor is calculated by dividing the number of citations in the current year to
articles published in the 2 previous years by the total number of articles published in the 2 previous
years.
Table 15 indicates the number of fellows' papers published in the top 10% of journals, based on the
JCR Impact Factor. Four hundred seventy-seven (477) of 1,257 papers were published in the top 10%
of journals, representing 37.95% of the fellows' papers. This indicates that more than one-third of the
fellows' papers are published in the highest quality journals as determined by the JCR Impact Factor,
which is 3.8 times higher than the expected percentage.

Immediacy Index. The JCR Immediacy Index is a measure of how quickly the average article in a
journal is cited. It indicates how often articles published in a journal are cited within the year they are
published. The Immediacy Index is calculated by dividing the number of citations to articles published
in a given year by the number of articles published in that year.
Table 16 indicates the number of fellows' papers published in the top 10% of journals, based on the
JCR Immediacy Index. Four hundred nineteen (419) of the 1,257 papers appear in the top 10% of
journals, representing 33.33% of the fellows' papers. This indicates that one-third of the fellows'
papers are published in the highest quality journals as determined by the JCR Immediacy Index, which
is 3.3 times higher than the expected percentage.

Hot Papers
ESI establishes citation thresholds for hot papers, which are selected from the highly cited papers in
different fields, but the time frame for citing and cited papers is much shorter—papers must be cited
within 2 years of publication and the citations must occur in a 2-month time period. Papers are
assigned to 2-month periods and thresholds are set for each period and field to select 0.1% of papers.
There were no hot papers identified for the current 2-month period (i.e., March-April 2007), but there
were a number of hot papers identified from previous periods.
Using the hot paper thresholds established by ESI as a benchmark, 20 hot papers, representing 1.59%
of the fellows' papers, were identified in five fields—Agricultural Sciences, Engineering,
Environment/Ecology, Geosciences, and Plant & Animal Science. The number of fellows' hot papers
is 16 times higher than expected. The hot papers are listed in Table 17.

Author Self-Citation
Self-citations are journal article references to articles from that same author (i.e., the first author).
Because higher author self-citation rates can inflate the number of citations, the author self-citation rate
was calculated for the fellows' papers. Of the 16,280 total cites, 844 are author self-cites—a 5.18%
author self-citation rate. Garfield and Sher3 found that authors working in research-based disciplines
tend to cite themselves on the average of 20% of the time. MacRoberts and MacRoberts4 claim that
approximately 10% to 30% of all the citations listed fall into the category of author self-citation.
Kovacic and Misak5 recently reported a 20% author self-citation rate for medical literature. Therefore,
the 5.18% self-cite rate for the fellows' papers is well below the range for author self-citation.
Highly Cited Researchers
A search of Thomson's ISIHighlyCited. com revealed that none of the former fellows are highly cited
researchers, which is to be expected because most of these individuals began their careers in the late
1990s. ISIHighlyCited.com is a database of the world's most influential researchers who have made
key contributions to science and technology during the period from 1981 to 1999.
