Caveats for the Use of Citation Indicators in Research and Journal Evaluations
TLDR
The assumption that citation and publication practices are homogenous within specialties and fields of science is invalid and the delineation of fields and among specialties is fuzzy.Abstract:
Ageing of publications, percentage of self-citations, and impact vary from journal to journal within fields of science. The assumption that citation and publication practices are homogenous within specialties and fields of science is invalid. Furthermore, the delineation of fields and among specialties is fuzzy. Institutional units of analysis and persons may move between fields or span different specialties. The match between the citation index and institutional profiles varies among institutional units and nations. The respective matches may heavily affect the representation of the units. Non-ISI journals are increasingly cornered into "transdisciplinary" Mode-2 functions with the exception of specialist journals publishing in languages other than English. An "externally cited impact factor" can be calculated for these journals. The citation impact of non-ISI journals will be demonstrated using Science and Public Policy as the example.read more

A comment to the paper by Waltman et al., Scientometrics, 87, 467---481, 2011
Tobias Opthof,Loet Leydesdorff +1 more
TL;DR: Comment is made using previously published data of Van Raan to address the pivotal issue of how the results of citation analysis correlate with the Results of peer review, and the lack of correlation with the peer-review based quality indicator applies equally to the newly developed ones.

Leveraging Citation Networks to Visualize Scholarly Influence Over Time
TL;DR: This approach uses an animated node-link diagram showing the citation network accumulated around the researcher over the course of the career in concert with key indicators, highlighting influence both within and across fields.

Bibliometric data in clinical cardiology revisited. The case of 37 Dutch professors.
TL;DR: There is too much inhomogeneity in citation characteristics even within a relatively homogeneous group of clinical cardiologists, therefore, citation analysis should be applied with great care in science policy.

A multidimensional approach to evaluating management journals: Refining PageRank via the differentiation of citation types and identifying the roles that management journals play
TL;DR: Two citation‐based approaches to facilitate a multidimensional evaluation of 39 selected management journals are introduced, including a refined application of PageRank via the differentiation of citation types and a form of mathematical manipulation to identify the roles that theselected management journals play.

Differences in the rank position of journals by Eigenfactor metrics and the five‐year impact factor in the Journal Citation Reports and the Eigenfactor Project web site
TL;DR: The differences in the scores and rank positions by the three new scientometric indicators of 52 journals in the Information and Library Science category were analysed to determine the range of differences and the extent of changes in rank positions.

The Strength of Weak Ties
TL;DR: In this paper, it is argued that the degree of overlap of two individuals' friendship networks varies directly with the strength of their tie to one another, and the impact of this principle on diffusion of influence and information, mobility opportunity, and community organization is explored.

An index to quantify an individual's scientific research output
TL;DR: The index h, defined as the number of papers with citation number ≥h, is proposed as a useful index to characterize the scientific output of a researcher.

A Set of Measures of Centrality Based on Betweenness
TL;DR: A family of new measures of point and graph centrality based on early intuitions of Bavelas (1948) is introduced in this paper, which define centrality in terms of the degree to which a point falls on the shortest path between others and there fore has a potential for control of communication.

The New Production of Knowledge: The Dynamics of Science and Research in Contemporary Societies
TL;DR: The authors argued that the ways in which knowledge is produced are undergoing fundamental changes at the end of the twentieth century and that these changes mark a distinct shift into a new mode of knowledge production which is replacing or reforming established institutions, disciplines, practices and policies.
