Abstract:

This paper addresses emerging trends in the collective dynamics found in knowledge networks, those networks composed of the relationships among knowledge sources, such as citation networks and keyword networks. In studying the formation and detection of new trends in the process of knowledge evolution, we use the collective dynamics approach to construct a network of knowledge clusters based on citation clustering. This approach explores the processes and rules of new trends emerging in knowledge clusters by examining the continuous changes in keyword vectors found in the interaction and coordination between evolving knowledge clusters. In direct citation networks, the collective dynamics approach is found to be superior to the baseline method, especially in predicting small knowledge fields with less data and more uncertainties.

Abstract:

The SNIP (source normalized impact per paper) indicator is an indicator of the citation impact of scientific journals. The indicator, introduced by Henk Moed in 2010, is included in Elsevier's Scopus database. The SNIP indicator uses a source normalized approach to correct for differences in citation practices between scientific fields. The strength of this approach is that it does not require a field classification system in which the boundaries of fields are explicitly defined.

In this paper, a number of modifications that were recently made to the SNIP indicator are explained, and the advantages of the resulting revised SNIP indicator are pointed out. It is argued that the original SNIP indicator has some counterintuitive properties, and it is shown mathematically that the revised SNIP indicator does not have these properties. Empirically, the differences between the original SNIP indicator and the revised one turn out to be relatively small, although some systematic differences can be observed. Relations with other source normalized indicators proposed in the literature are discussed as well. (c) 2012 Elsevier Ltd. All rights reserved.

A mathematical characterization of the Hirsch-index by means of minimal increments

Hirsch-index, h-Index, Characterization, Increment

Abstract:

The minimum configuration to have a h-index equal to h is h papers each having h citations, hence h(2) citations in total. To increase the h-index to h + 1 we minimally need (h + 1)(2) citations, an increment of I-1(h) = 2h + 1. The latter number increases with 2 per unit increase of h. This increment of the second order is denoted I-2(h) =2.

If we define I-1 and I-2 for a general Hirsch configuration (say n papers each having f(n) citations) we calculate I-1(f) and I-2(f) similarly as for the h-index. We characterize all functions f for which I-2(f) = 2 and show that this can be obtained for functions f(n) different from the h-index. We show that f(n) = n (i.e. the h-index) if and only if I-2(f) = 2, f(1) = 1 and f(2) = 2.

We give a similar characterization for the threshold index (where n papers have a constant number C of citations). Here we deal with second order increments I-2(f) = 0. (c) 2013 Elsevier Ltd. All rights reserved.

Title:

Correlation between variables subject to an order restriction, with application to scientometric indices

Abstract:

Variables subject to an order restriction, for instance Y <= X, have a bivariate distribution over a non-rectangular joint domain that entails a non-null and potentially large structural relation even if the variables show no association (in the sense that particular ranges of values of X do not co-occur with particular ranges of values of Y). Order restrictions affect a number of scientometric indices (including the h index and its variants) that are routinely subjected to correlational analyses to assess whether they provide redundant information, but these correlations are contaminated by the structural relation. This paper proposes an alternative definition of association between variables subject to an order restriction that eliminates their structural relation and reverts to the conventional definition when applied to variables that are not subject to order restrictions. This alternative definition is illustrated in a number of theoretical cases and it is also applied !

to empirical data involving scientometric indices subject to an order restriction. A test statistic is also derived which allows testing for the significance of an association between variables subject to an order restriction. (c) 2013 Elsevier Ltd. All rights reserved.

Abstract:

In this paper we provide the reader with a visual representation of relationships among the impact of book chapters indexed in the Book Citation Index using information gain values and published by different academic publishers in specific disciplines. The impact of book chapters can be characterized statistically by citations histograms. For instance, we can compute the probability of occurrence of book chapters with a number of citations in different intervals for each academic publisher. We predict the similarity between two citation histograms based on the amount of relative information between such characterizations. We observe that the citation patterns of book chapters follow a Lotkaian distribution. This paper describes the structure of the Book Citation Index using 'heliocentric clockwise maps' which allow the reader not only to determine the grade of similarity of a given academic publisher indexed in the Book Citation Index with a specific discipline according to !

their citation distribution, but also to easily observe the general structure of a discipline, identifying the publishers with higher impact and output. (c) 2013 Elsevier Ltd. All rights reserved.

Abstract:

Analysis of 131 publications during 2006-2007 by staff of the School of Environmental Science and Management at Southern Cross University reveals that the journal impact factor, article length and type (i.e., article or review), and journal self-citations affect the citations accrued to 2012. Authors seeking to be well cited should aim to write comprehensive and substantial review articles, and submit them to journals with a high impact factor which has previously carried articles on the topic. Nonetheless, strategic placement of articles is complementary to, and no substitute for careful crafting of good quality research. Evidence remains equivocal regarding the contribution of an author's prior publication success (h-index) and of open-access journals. Crown Copyright (c) 2012 Published by Elsevier Ltd.

Abstract:

China's status as a scientific power, particularly in the emerging area of nanotechnology, has become widely accepted in the global scientific community. The role of knowledge spillover in China's nanotechnology development is generally assumed, albeit without much convincing evidence. Very little has been investigated on the different mechanisms of knowledge spillover. Utilizing both cross-sectional data and longitudinal data of 77 Chinese nanoscientists' publications, this study aims to differentiate individual effects from the effect of international collaboration on the research performance of Chinese researchers. The study finds evidence in support of the "birds of a feather flock together" argument - that China's best scientists collaborate at international level. It also finds that collaboration across national boundaries has a consistently positive effect on China's nano research quality with a time-decaying pattern. Language turns out to be the most influential fact!

or impacting the quality or visibility of Chinese nano research. Policy implications on research evaluation, human capital management, and public research and development allocation are also discussed in the end. (c) 2012 Elsevier Ltd. All rights reserved.

Abstract:

The evaluation of performance at the individual level is of fundamental importance in informing management decisions. The literature provides various indicators and types of measures, however a problem that is still unresolved and little addressed is how to compare the performance of researchers working in different fields (apples to oranges). In this work we propose a solution, testing various scaling factors for the distributions of research productivity in 174 scientific fields. The analysis is based on the observation of scientific production by all Italian university researchers active in the hard sciences over the period 2004-2008, as indexed by the Web of Science. The most effective scaling factor is the average of the productivity distribution of researchers with productivity above zero. (c) 2013 Elsevier Ltd. All rights reserved.

Abstract:

The arbitrariness of the h-index becomes evident, when one requires q x h instead of h citations as the threshold for the definition of the index, thus changing the size of the core of the most influential publications of a dataset. I analyze the citation records of 26 physicists in order to determine how much the prefactor q influences the ranking. Likewise, the arbitrariness of the highly-cited-publications indicator is due to the threshold value, given either as an absolute number of citations or as a percentage of highly cited papers. The analysis of the 26 citation records shows that the changes in the rankings in dependence on these thresholds are rather large and comparable with the respective changes for the h-index.

Abstract:

In this paper we attempt to assess the impact of journals in the field of forestry, in terms of bibliometric data, by providing an evaluation of forestry journals based on data envelopment analysis (DEA). In addition, based on the results of the conducted analysis, we provide suggestions for improving the impact of the journals in terms of widely accepted measures of journal citation impact, such as the journal impact factor (IF) and the journal h-index. More specifically, by modifying certain inputs associated with the productivity of forestry journals, we have illustrated how this method could be utilized to raise their efficiency, which in terms of research impact can then be translated into an increase of their bibliometric indices, such as the h-index, IF or eigenfactor score.

How relevant is the predictive power of the h-index? A case study of the time-dependent Hirsch index

Abstract:

The h-index has been shown to have predictive power. Here I report results of an empirical study showing that the increase of the h-index with time often depends for a long time on citations to rather old publications. This inert behavior of the h-index means that it is difficult to use it as a measure for predicting future scientific output. (c) 2013 Elsevier Ltd. All rights reserved.

Abstract:

Academic productivity and research funding have been hot topics in biomedical research. While publications and their citations are popular indicators of academic productivity, there has been no rigorous way to quantify co-authors' relative contributions. This has seriously compromised quantitative studies on the relationship between academic productivity and research funding. Here we apply an axiomatic approach and associated bibliometric measures to revisit a recent study by Ginther et al. (Ginther et al., 2011a,b) in which the probability of receiving a U.S. National Institutes of Health (NIH) R01 award was analyzed with respect to the applicant's race/ethnicity. Our results provide new insight and suggest that there is no significant racial bias in the NIH review process, in contrast to the conclusion from the study by D. K. Ginther et al. Our axiomatic approach has a potential to be widely used for scientific assessment and management. (c) 2012 Elsevier Ltd. All rights r!

Abstract:

Hypes occur in every domain of human behavior, including scientific research. We show in this contribution that journals and authors who studied the h-index benefited in terms of short-term citations. As, moreover, the introduction of the h-index is more a 'clever find' than a first rate intellectual achievement, its rise can be compared to a stock market bubble. (c) 2012 Elsevier Ltd.

Abstract:

Since its introduction, the Journal Impact Factor has probably been the most extensively adopted bibliometric indicator. Notwithstanding its well-known strengths and limits, it is still widely misused as a tool for evaluation, well beyond the purposes it was intended for. In order to shed further light on its nature, the present work studies how the correlation between the Journal Impact Factor and the (time-weighed) article Mean Received Citations (intended as a measure of journal performance) has evolved through time. It focuses on a sample of hard sciences and social sciences journals from the 1999 to 2010 time period. Correlation coefficients (Pearson's Coefficients as well as Spearman's Coefficients and Kendall's tau(alpha)) are calculated and then tested against several null hypotheses. The results show that in most cases Journal Impact Factors and their yearly variations do not display a strong correlation with citedness. Differences also exist among scientific areas.!

Abstract:

We propose a cross-field evaluation method for the publications of research institutes. With this approach, we first determine a set of the most visible publications (MVPs) for each field from the publications of all assessed institutes according to the field's h-index. Then, we measure an institute's production in each field by its percentage share (i.e., contribution) to the field's MVPs. Finally, we obtain an institute's cross-field production measure as the average of its contributions to all fields. The proposed approach is proven empirically to be reasonable, intuitive to understand, and uniformly applicable to various sets of institutes and fields of different publication and citation patterns. The field and cross-field production measures obtained by the proposed approach not only allow linear ranking of institutes, but also reveal the degree of their production difference.
