TITLE :  Bibliometric analysis of tsunami research

Abstract 

The use of the bibilometric analytical technique for examining tsunami 
research does not exist in the literature. The objective of the study was 
to perform a bibliometric analysis of all tsunami-related publications in 
the Science Citation Index (SCI). Analyzed parameters included document 
type, language of publication, publication output, authorship, publication 
patterns, distribution of subject category, distribution of author 
keywords, country of publication, most-frequently cited article, and 
document distribution after the Indonesia tsunami. The US and Japan 
produced 53% of the total output where the seven major industrial countries 
accounted for the majority of the total production. English was the 
dominant language, comprising 95% of articles. A simulation model was 
applied to describe the relationship between the number of authors and the 
number of articles, the number of journals and the number of articles, and 
the percentage of total articles and the number of times a certain keyword 
was used. Moreover the tsunami publication patterns in the first 8 months 
after the Indonesia tsunami occurred on 26 December 2004 indicated a high 
percentage of non-article publications and more documents being published 
in journals with higher impact factors.

TITLE  :  Hirsch index or Hirsch rate? Some thoughts arising 
          from Liang’s data

Abstract

Hirsch’s h-index gives a single number that in some sense summarizes an 
author’s research output and its impact. Since an individual author’s h-
index will be time-dependent, we propose instead the h-rate which, 
according to theory, is (almost) constant. We re-analyse a previously 
published data set (LIANG, 2006) which, although not of the precise form to 
properly test our model, reveals that in many cases we do not have a 
constant h-rate. On the other hand this then suggests ways in which deeper 
scientometric investigations could be carried out. This work should be 
viewed as complementary to that of LIANG (2006).

TITLE  :  Issued US patents, patent-related global academic and media 
publications, and the US market indices are inter-correlated, with varying 
growth patterns

Abstract

The increase in patents is a main driving force for discussions of 
international competitiveness, knowledge spillovers, patent office 
efficiencies, and others. However, to the author’s knowledge, it is 
interesting that no work has investigated the impact of the growth in the 
number of patents on patent-related scholarly (peer-reviewed) and media 
(e.g., press release) literatures, or evidence of inter-relatedness among 
these three literatures with those of the US market indices (viz., Dow, 
S&P500, NASDAQ). Here, I report that the growth in the number of US issued 
patents, the patentrelated media and peer-reviewed publications, and these 
indices are statistically correlated, but with drastically different growth 
rates. This general result affords data supporting a hypothesis that 
publicly traded companies, as drivers of innovation, are priming a new 
research area within the scholarly communities and simultaneously affecting 
market value through, what-may-be-called, “patent journalism.”

TITLE :  Who’s who and what’s what in Brazilian Public Health Sciences

Abstract

Introduction: The present study endeavours to provide information on what 
are the research interests of Brazilian Public Health and how authors can 
be ranked.
Methods: Post-graduate faculty members ISI data are analysed according to 
regions. Number of paper and its citations, papers’ type-complexity-
cooperation, Bradford’s Law, Shannon’s indexes, time dynamic functions, 
Lotka’s Law, and ranking functions are examined.
Results: Current production was built up in the last 30 years at a rate of 
9.6% articles/year and 12.6% citations/year. 66% of potential authors were 
present in ISI data records, 64% achieved at least one citation. Research 
fields do not much depart from the traditional PH purview. More than 66% of 
authors have just one paper and decrease is steep. Subtle differences call 
attention to the South region.
Conclusion: Brazilian PH is mainly committed to classical research fields 
and ranking among authors is narrow.

Abstract

Our aim is to compare the coverage of the Scopus database with that of 
Ulrich, to determine just how homogenous it is in the academic world. The 
variables taken into account were subject distribution, geographical 
distribution, distribution by publishers and the language of publication. 
The analysis of the coverage of a product of this nature should be done in 
relation to an accepted model, the optimal choice being Ulrich’s Directory, 
considered the international point of reference for the most comprehensive 
information on journals published throughout the world. The results 
described here allow us to draw a profile of Scopus in terms of its 
coverage by areas – geographic and thematic – and the significance of peer-
review in its publications. Both these aspects are highly pragmatic 
considerations for information retrieval, the evaluation of research, and 
the design of policies for the use of scientific databases in scientific 
promotion.

TITLE  :  Journal self-citation rates in ecological sciences

Abstract

Impact factors are a widely accepted means for the assessment of journal 
quality. However, journal editors have possibilities to influence the 
impact factor of their journals, for example, by requesting authors to cite 
additional papers published recently in that journal thus increasing the 
self-citation rate. I calculated self-citation rates of journals ranked in 
the Journal Citation Reports of ISI in the subject category “Ecology” (n = 
107). On average, self citation was responsible for 16.2 ± 1.3% (mean ± SE) 
of the impact factor in 2004. The self-citation rates decrease with 
increasing journal impact, but even high impact journals show large 
variation. Six journals suspected to request for additional citations 
showed high self-citation rates, which increased over the last seven years. 
To avoid further deliberate increases in self-citation rates, I suggest to 
take journal-specific self-citation rates into account for journal rankings.

Abstract

The authors present ranked lists of world’s countries – with main focus on 
EU countries (together with newly acceeded and candidate countries) – by 
their h-index on various science fields. As main source of data Thomson 
Scientific’s Essential Science Indicators (ESI) database was used. EU 
countries have strong positions in each field but none of them can 
successfully compete with the USA. The modest position of the newly 
accessed and candidate countries illustrate the importance of supportive 
economic and political background in order to achieve scientific success. 
An attempt is made to fit a recent theoretical model relating the h-index 
with two traditional scientometric indicators: the number of publications 
and the mean citation rate.
