TITLE: What Do Federal District Judges Want? An Analysis of
Publications, Citations, and Reversals (Article, English)

ABSTRACT: Evidence from a data set of federal district judges from
2001 and 2002 suggests that district judges adjust their opinion-writing
practices to minimize their workload while maximizing their reputation
and chance for elevation to a higher court. District judges in circuits
with politically uniform circuit judges are better able to predict what
opinions will get affirmed by the circuit court, leading to higher
publication rates and a higher affirmance rate. In contrast, district
judges in circuits with politically diverse circuit judges are less able
to predict the preferences of the reviewing circuit court panel, leading
district judges to publish fewer but higher-quality opinions in an effort
to maximize their affirmance rate (JEL K40, K41, K49).

ABSTRACT: Background: Fewer dermatologists than other clinical
specialists are entering and being retained as physicians in the Canadian
medical workforce. Studies suggest that dermatologist numbers may
influence skin disease outcomes. No study has questioned whether the
number of clinical dermatologists can influence academic productivity.
Objective: To quantify the correlation of the number of dermatologists
with biomedical scientific production in this field from 1996 to 2008 in
Canada.
Methods: Canadian dermatology biomedical scientific production from
SCImago Journal & Country Rank (SJR) were merged with Canadian Medical
Association (CMA) dermatologist demographic data. Linear regression
analyses were used to model the relationships.
Results: The low growth of dermatologist numbers by 8.16% in Canada from
1996 to 2008 correlates with a small increase in articles by 7.59%
published in this subject area during this period. This has reduced the
scientific importance of Canadian dermatology in the world.
Conclusion: The number of dermatologists was a significant predictor of
biomedical research production in the field of dermatology. This suggests
that specialist availability may be one factor influencing dermatology
research and publications.

ABSTRACT: Purpose - The aim of this article is to study a locally-
oriented and book-based research field using two Swedish language
sources. Knowledge about citation patterns outside journal-based, English
language databases is scarce; thus a substantial part of research in the
humanities and the social sciences is neglected in bibliometric studies.
Design/methodology/approach - Citation characteristics (publication type,
language, gender and age) in the journal Tidskrift for
Litteraturvetenskap (2000-2009) and in grant applications (2006-2009) are
studied. The datasets are analyzed further, adopting an author-co-
citation approach for depicting and comparing the "intellectual base" of
the field.
Findings - It is shown that monographs and anthologies are the main
publication channel in Swedish literary research. English, followed by
Swedish, is the major language, and the gender of authors seems to
influence citation practices. Furthermore, a common intellectual base of
literary studies that is independent of publication type and language
could be identified.
Practical implications - Bibliometric analysis of fields within the
humanities needs to go beyond established databases and materials. The
extensive use of recent English language monographs in Swedish literary
studies informs the acquisition policy of university libraries serving
literature scholars.
Originality/value - Citation analysis of non-English sources offers
further knowledge about scholarly fields with a local and "rural"
profile. The approach of using references in grant applications provides
a novel and promising venue for bibliometric research.

ABSTRACT: Science studies have not yet provided a heuristic that
distinguishes creative accomplishments from other research contributions.
Likewise, there is no commonly agreed typology of creative scientific
results. This article takes up these two desiderata. It is argued that
scientific creativity springs from the fundamental tension between
originality and scientific relevance. Based on this consideration, a
heuristic is introduced that singles out creative research
accomplishments from other contributions in science. Furthermore, it is
shown that creative contributions are not only advances in theory, but
also new methods, new empirical phenomena, and the development of new
research instrumentation. The article introduces examples from science
history and presents results from bibliometric studies.

ABSTRACT: 'Discometrics', a long neglected area of informetric
studies was revisited in a network context. Cooperation between jazz
musicians was analysed using the recent 'Hirschian' concepts of network
informetrics. Partnership Ability Index (phi) was found to be a useful
measure to characterize the way performers are embedded in their
partnership network. Indications of some positive relations between phi
and other 'qualities' of the performers were found. (C) 2012 Elsevier

ABSTRACT: We propose two new indices that are able to measure a
scientific researcher's overall influence and the level of his/her works'
association with the main-stream research subjects within a scientific
field. These two new measures - the total influence index and the
mainstream index - differ from traditional performance measures such as
the simple citation count and the h-index in that they take into account
the indirect influence of an author's work. Indirect influence describes
a scientific publication's impact upon subsequent works that do not
reference it directly. The two measures capture indirect influence
information from the knowledge emanating paths embedded in the citation
network of a target scientific field. We take the Hirsch index, data
envelopment analysis, and lithium iron phosphate battery technology field
to examine the characteristics of these two measures. The results show
that the total influence index favors earlier researchers and
successfully highlights those researchers who have made crucial
contributions to the target scientific field. The main-stream index, in
addition to underlining total influence, also spotlights active
researchers who enter into a scientific field in a later development
stage. In summary, these two new measures are valuable complements to
traditional scientific performance measures. (C) 2012 Elsevier Ltd. All

ABSTRACT: The relationship between researchers' publishing and
citing behaviours has received little examination despite its potential
importance in scholarly communication, particularly at an international
level. To remedy this we studied documents and their references indexed
in Thomson Reuters's Web of Science (WoS) in the period 2000-2009 to
compare journal publishing behaviours against journal citing behaviours
across the world. The results reveal that most publications in, and
citations to, all five quality based strata of journals examined come
from scientifically and economically advanced countries. Nevertheless, in
proportion to their total number of citations given to WoS journals, it
seems that less developed countries cite high-quality journals at the
same rate as developed countries and so the poorer publishing of less
developed countries does not seem to be due to a lack of access to top
journals. Moreover, examining the publishing and citing trends of
countries revealed a decreasing rate of high-income and Scientifically
Advanced Countries (SACs) publications in, and citations to, all quality
ranges of journals in comparison to the increasing rate of publications
and citations of other groups. Finally, research cooperation between
developed and less developed countries seems to positively influence the
publishing behaviour of the latter as their publications co-authored with
developed countries were published more often in top journals. (C) 2012

ABSTRACT: The paper first introduces the basic problems of author
bibliographic coupling including the relationship between author
bibliographic coupling and document bibliographic coupling as well as the
three calculation methods of author coupling strength, namely, simple
method, minimum method and combined method. Next I choose a small sample
of authors in Chinese library and information science (LIS) as the
research objects to have a comparative analysis of three types of author
coupling strength algorithms (the data source is from the Chinese Social
Sciences Citation Index (CSSCI)). The result shows that the minimum
method is the most appropriate one to calculate the author coupling
strength. Then a large sample of authors is chosen to analyze the
intellectual structure of Chinese LIS. The result shows that author
bibliographic coupling analysis (ABCA) can discover the intellectual
structure of a discipline better. It is also found that compared with
author cocitation analysis (ACA), ABCA has the advantage that it not only
can discover the intellectual structure of a discipline more
comprehensively and concretely but also can reflect the research frontier
of the discipline. Finally, some practical problems that arise during
this research are discussed. (C) 2012 Elsevier Ltd. All rights reserved.

ABSTRACT: This paper investigates the citation impact of three
large geographical areas - the U.S., the European Union (EU), and the
rest of the world (RW) - at different aggregation levels. The difficulty
is that 42% of the 3.6 million articles in our Thomson Scientific dataset
are assigned to several sub-fields among a set of 219 Web of Science
categories. We follow a multiplicative approach in which every article is
wholly counted as many times as it appears at each aggregation level. We
compute the crown indicator and the Mean Normalized Citation Score (MNCS)
using for the first time sub-field normalization procedures for the
multiplicative case. We also compute a third indicator that does not
correct for differences in citation practices across sub-fields. It is
found that: (1) No geographical area is systematically favored (or
penalized) by any of the two normalized indicators. (2) According to the
MNCS, only in six out of 80 disciplines - but in none of 20 fields - is
the EU ahead of the U.S. In contrast, the normalized U.S./EU gap is
greater than 20% in 44 disciplines, 13 fields, and for all sciences as a
whole. The dominance of the EU over the RW is even greater. (3) The U. S.
appears to devote relatively more - and the RW less - publication effort
to sub-fields with a high mean citation rate, which explains why the
U.S./EU and EU/RW gaps for all sciences as a whole increase by 4.5 and
5.6 percentage points in the un-normalized case. The results with a
fractional approach are very similar indeed. (C) 2012 Elsevier Ltd. All

ABSTRACT: The process of assessing individual authors should rely
upon a proper aggregation of reliable and valid papers' quality metrics.
Citations are merely one possible way to measure appreciation of
publications. In this study we propose some new, SJR- and SNIP-based
indicators, which not only take into account the broadly conceived
popularity of a paper (manifested by the number of citations), but also
other factors like its potential, or the quality of papers that cite a
given publication. We explore the relation and correlation between
different metrics and study how they affect the values of a real-valued
generalized h-index calculated for 11 prominent scientometricians. We
note that the h-index is a very unstable impact function, highly
sensitive for applying input elements' scaling. Our analysis is not only
of theoretical significance: data scaling is often performed to normalize
citations across disciplines. Uncontrolled application of this operation
may lead to unfair and biased (toward some groups) decisions. This puts
the validity of authors assessment and ranking using the h-index into
question. Obviously, a good impact function to be used in practice should
not be as much sensitive to changing input data as the analyzed one. (C)

ABSTRACT: Project funding is an increasingly important mode of
research funding. The rationale is that through project funding new
fields and new themes can be supported more effectively. Furthermore,
project funding improves competition, which is expected to select the
better research projects and researchers. However, project funding has a
price, as it requires researchers to invest time in reviewing proposals,
and to participate in selection committees. In that perspective,
selection committee membership can be seen as a service to the scholarly
community.
However, what do committee members themselves get from membership? In
this paper we show that committee members in average are more successful
in grant applications than other principle investigators, and this is not
explained by performance differences. The findings suggest that committee
membership is not only service, but also self-service. (C) 2012 Elsevier

ABSTRACT: In this paper, we discussed the feasibility of early
recognition of highly cited papers with citation prediction tools.
Because there are some noises in papers' citation behaviors, the soft
fuzzy rough set (SFRS), which is well robust to noises, is introduced in
constructing the case-based classifier (CBC) for highly cited papers.
After careful design that included: (a) feature reduction by SFRS; (b)
case selection by the combination use of SFRS and the concept of case
coverage; (c) reasoning by two classification techniques of case coverage
based prediction and case score based prediction, this study demonstrates
that the highly cited papers could be predicted by objectively assessed
factors. It shows that features included the research capabilities of the
first author, the papers' quality and the reputation of journal are the
most relevant predictors for highly cited papers. (C) 2012 Elsevier Ltd.

ABSTRACT: The study tries to construct the diffusion models of
crisis information in micro blog. We propose three information release
patterns in micro blog according to the duration of crisis information
released, namely concentrated release, continuous release, and pulse
release. Based on Logistic function, three respective diffusion models
are constructed. We choose three crisis events to test the diffusion
models using the variables of the number of micro blogs with the crisis
information (NMCI) and the increment of NMCI. The estimate results show
that the diffusion of crisis information in micro blogs can be described
by Logistic function, and the growth curve of NMCI is S-shaped. (C) 2012

measuring both weighted networks and directed networks. After analyzing

KEYWORDS: Citation based indicator (CBI); Combined impact indicator

ABSTRACT: Metrics based on percentile ranks (PRs) for measuring
scholarly impact involves complex treatment because of various defects
such as overvaluing or devaluing an object caused by percentile ranking
schemes, ignoring precise citation variation among those ranked next to
each other, and inconsistency caused by additional papers or citations.
These defects are especially obvious in a small-sized dataset. To avoid
the complicated treatment of PRs based metrics, we propose two new
indicators-the citation-based indicator (CBI) and the combined impact
indicator (CII). Document types of publications are taken into account.
With the two indicators, one would no more be bothered by complex issues
encountered by PRs based indicators. For a small-sized dataset with less
than 100 papers, special calculation is no more needed. The CBI is based
solely on citation counts and the CII measures the integrate
contributions of publications and citations. Both virtual and empirical
data are used so as to compare the effect of related indicators. The CII
and the PRs based indicator I3 are highly correlated but the former
reflects citation impact more and the latter relates more to
publications. (C) 2012 Elsevier Ltd. All rights reserved.

research fields, appropriate standardization must be applied as part of
any bibliometric analysis of the productivity of individual scientists
and research organizations. Such standardization involves scaling by some
factor that characterizes the distribution of the citations of articles
from the same year and subject category. In this work we conduct an
analysis of the sensitivity of researchers' productivity rankings to the
scaling factor chosen to standardize their citations. To do this we first
prepare the productivity rankings for all researchers (more than 30,000)
operating in the hard sciences in Italy, over the period 2004-2008. We
then measure the shifts in rankings caused by adopting scaling factors
other than the particular factor that seems more effective for comparing
the impact of publications in different fields: the citation average of
the distribution of cited-only publications. (C) 2012 Elsevier Ltd. All

ABSTRACT: The aim of this brief communication is to reply to a
letter by Kosmulski (Journal of Informetrics 6(3):368-369, 2012), which
criticizes a recent indicator called "success-index". The most
interesting features of this indicator, presented in Franceschini et al.
(Scientometrics, in press), are: (i) allowing the selection of an "elite"
subset from a set of publications and (ii) implementing the field-
normalization at the level of an individual publication. We show that the
Kosmulski's criticism is unfair and inappropriate, as it is the result of
a misinterpretation of the indicator. (C) 2012 Elsevier Ltd. All rights

ABSTRACT: A new size-independent indicator of scientific journal
prestige, the SJR2 indicator, is proposed. This indicator takes into
account not only the prestige of the citing scientific journal but also
its closeness to the cited journal using the cosine of the angle between
the vectors of the two journals' cocitation profiles. To eliminate the
size effect, the accumulated prestige is divided by the fraction of the
journal's citable documents, thus eliminating the decreasing tendency of
this type of indicator and giving meaning to the scores. Its method of
computation is described, and the results of its implementation on the
Scopus 2008 dataset is compared with those of an ad hoc Journal Impact
Factor, JIF(3y), and SNIP, the comparison being made both overall and
within specific scientific areas. All three, the SJR2 indicator, the SNIP
indicator and the JIF distributions, were found to fit well to a
logarithmic law. Although the three metrics were strongly correlated,
there were major changes in rank. In addition, the SJR2 was distributed
more equalized than the JIF by Subject Area and almost as equalized as
the SNIP, and better than both at the lower level of Specific Subject
Areas. The incorporation of the cosine increased the values of the flows
of prestige between thematically close journals. (C) 2012 Elsevier Ltd.

ABSTRACT: Citation curves for researchers with the same h index can
vary greatly in the heaviness of their top (excess citations to core
papers) or the heaviness of their tail (citations to non-core papers),
revealing quantitative differences across researchers. Also, promotion to
the next higher h depends only on citations received by a small subset of
papers, so that researchers with a given h may have citation curves whose
top and tail reveal a weaker impact than that of researchers with a lower
h. To overcome these problems, we propose a two-sided h index, an
extension that computes additional h indices progressively up the top and
out the tail of the citation curve. This extension represents a citation
curve descriptor one of whose elements is the scalar h. The advantages of
the two-sided h index are illustrated through analysis of citation curves
for 88 researchers with h indices ranging from 8 to 20. Several schemes
are also discussed that use the two-sided h index to define criteria for
ranking researchers within and across scalar h indices, according to
whether the top of the citation curve, its tail, or both are deemed
relevant under the circumstances in which research accomplishments are
assessed. (C) 2012 Elsevier Ltd. All rights reserved.

ABSTRACT: Evaluating the performance of institutions with different
resources is not easy, any citation distribution comparisons are strongly
affected by the differences in the number of articles published. The
paper introduces a method for comparing citation distributions of
research groups that differ in size. The citation distribution of a
larger group is reduced by a certain factor and compared with the
original distribution of a smaller group. Expected values and tolerance
intervals of the reduced set of citations are calculated. A comparison of
both distributions can be conveniently viewed in a graph. The size-
independent reduced Hirsch index - a function of reducing factor that
allows the comparison of groups within a scientific field - is calculated
in the same way. The method can be used for comparing groups or units
differing in full-time equivalent, funding or the number of researchers,
for comparing countries by population, gross domestic product, etc. It is
shown that for the calculation of the reduced Hirsch index, the upper
part of the original citation distribution is sufficient. The method is
illustrated through several case comparisons. (C) 2012 Elsevier Ltd. All

ABSTRACT: Despite the huge amount of literature concerning the h-
index, few papers have been devoted to its statistical analysis when a
probabilistic distribution is assumed for citation counts. The present
contribution mainly aims to divulge the inferential techniques recently
introduced by Pratelli et al. (2012), by explaining the details for
proper point and set estimation of the theoretical h-index. Moreover,
some new achievements on simultaneous inference - addressed to produce
suitable scholar comparisons - are carried out. Finally, the analysis of
the citation dataset for the Nobel Laureates (in the last five years) and
for the Fields medallists (from 2002 onward) is considered in order to
exemplify the theoretical issues. (C) 2012 Elsevier Ltd. All rights

ABSTRACT: In this work, an analysis of scientific bibliographic
productivity was made using the Faculdade de Filosofia e Ciencias,
Universidade Estadual Paulista (FFC-UNESP) as example. It is composed by
nine departments which offer altogether nine undergraduate courses: 1)
Archival, 2) Library, 3) Speech Therapy, 4) Pedagogy, 5) International
Relations, 6) Physiotherapy, 7) Occupational Therapy, 8) Philosophy, 9)
Social Sciences and six graduate programs leading to M. S. and Ph.D.
degrees. Moreover, when analyzing the different courses of FFC-UNESP,
they represent typical academic organization in Brazil and Latin America
and could be taken as a model for analyzing other Brazilian research
institutions. Using data retrieved from the Lattes Plataform database
(Curriculum Lattes) we have quantitatively the scientific productivity
percentage of professors at UNESP. We observed that bibliometric
evaluations using the Curriculum Lattes (CL) showed that the professors
published papers in journal are not indexed by ISI and SCOPUS. This
analysis was made using: 1) the total number of papers (indexed in
Curriculum Lattes database), 2) the number of papers indexed by Thomson
ISI Web of Science database and SCOPUS database, and 3) the Hirsch (h-
index) by ISI and SCOPUS. Bibliometric evaluations of departments showed
a better performance of Political Science and Economics Department when
compared to others departments, in relation total number of papers
(indexed in Curriculum Lattes database). We also analyzed the academic
advisory (Master's Thesis and Ph. D. Thesis) by nine departments of
FFC/UNESP. The Administration and School Supervision Department presented
a higher academic advisory (concluded and current) when compared to the
others departments.

ABSTRACT: In Brazil and in many countries around the world, soccer,
in addition to being a competition or professional activity, has been
considered a leisure activity and entertainment. In soccer matches,
different to what happens in other cultural events, there is a passionate
participation of people. If, in one hand, this makes the spectacle even
greater, with expression of joy, it could, on the other hand, also cause
violence and destruction. Currently, the increase of violence in football
stadiums has generated significant concern to the authorities, especially
police forces, involved in undertaking actions to reduce risks during
soccer matches. However, this process lacks scientific grounds. The aim
of this exploratory and descriptive paper is to build up knowledge about
the theme for researchers through the bibliometric analysis of
international literature, by using the ProKnow-C process ( Knowledge
Development Process - Constructivist). We searched articles published
between 2001 and 2010 in scientific journals available on the CAPES
website. The research resulted in a Bibliographic Portfolio composed by
14 scientifically sound articles, aligned with the researchers view on
the theme "Risk management in soccer stadiums". These articles were
analyzed to identify: the main journals, articles, authors and keywords.
It is concluded that the process used has provided the researchers with
the knowledge of the state of the art on the theme, allowing the
continuation of the research.
