Growth Rates of Knowledge

Nick Zhang

This is an evolving document. It is devoted to summarizing patterns and laws of knowledge growth. By examining a variety of parameters in data sources such as Wikipedia and Microsoft Academic Graph, we can get deeper insights of how knowledge evolves.

With Registered Reports Towards Large Scale Data Curation

Steffen Herbold

The scale of manually validated data is currently limited by the effort that small groups of researchers can invest for the curation of such data. Within this paper, we propose the use of registered reports to scale the curation of manually validated data. The idea is inspired by the mechanical turk and replaces monetary payment with authorship of data set publication.

On the rules of science game

Endel Poder

Credit allocation in the mainstream bibliometrics is fundamentally flawed and the popular indicators have been misleading science for decades. Originally a simple technical mistake has become an integral part of our culture and is very difficult to correct. Although the problem has been raised in scientific articles, it seems mostly unknown to wider audience.

Distribution of scientific journals impact factor

Michael Romanovsky

We consider distributions of scientific journals impact factor. Analysing 9028 scientific journals with the largest impact factors, we found that the distribution of them is year-to-year stable (at least for analysed 2011-2013 years), and it has the character of the exponential Boltzmann distribution with the power law asymptotic (tail).

Which differences can be expected when two universities in the Leiden Ranking are compared? Some benchmarks for institutional research evaluations

Lutz Bornmann, Wolfgang Glänzel

The comparison of two universities in terms of bibliometric indicators frequently faces the problem of assessing the differences as meaningful or not. This Letter to the Editor proposes some benchmarks which can be used for supporting the interpretation of institutional differences.

Digital Archives as Big Data

Luis Martinez-Uribe

Digital archives contribute to Big data. Combining social network analysis, coincidence analysis, data reduction, and visual analytics leads to better characterize topics over time, publishers' main themes and best authors of all times, according to the British newspaper The Guardian and from the 3 million records of the British National Bibliography.

Carnot Efficiency of Publication

Abhisek Ukil

This paper analyzes publication efficiency in terms of Hirsch-index or h-index and total citations, with an analogy to the Carnot efficiency used in thermodynamics. Such publication efficiency, with typical value of 30%, can be utilized to normalize the research output judgment, favoring quality outputs in reduced quantity, which is currently lacking in many discipline.

Scientific wealth and inequality within nations

Gangan Prathap

We show that the greater the scientific wealth of a nation, the more likely that it will tend to concentrate this excellence in a few premier institutions. That is, great wealth implies great inequality of distribution. The scientific wealth is interpreted in terms of citation data harvested by Google Scholar Citations for profiled institutions from all countries in the world.

The Journal Impact Factor Should Not Be Discarded

Lutz Bornmann, Alexander I. Pudovkin

The Journal Impact Factor (JIF) has been heavily criticized over decades. This opinion piece argues that the JIF should not be demonized. It still can be employed for research evaluation purposes by carefully considering the context and academic environment.

Triclosan alters antimicrobial and inflammatory responses of epithelial cells

MA Wallet, NL Calderon, TR Alonso et al.

Periodontal diseases are a class of pathologies wherein oral microbes induce harmful immune responses in a susceptible host. Therefore, an agent that can both reduce microbial burden and lessen pathogenesis of localized inflammation would have beneficial effects in periodontal disease; 2,4,4‐trichloro‐2‐hydroxydiphenyl‐ether [triclosan] is currently used in oral care products owing to broad spectrum antimicrobial and anti‐inflammatory properties.ObjectiveTo determine effects of triclosan on the response of oral epithelial cells to stimulation with the inflammatory microbial product lipopolysaccharide (LPS), a ligand for toll‐like receptor 4 [TLR4].Materials/MethodsPrimary human oral epithelial cells were stimulated with LPS in the presence and/or absence of triclosan after which expression of pro‐inflammatory cytokines, β‐defensins, micro‐RNAs [miRNAs], or TLR‐signaling pathway proteins were evaluated.ResultsHere, we demonstrate that triclosan is a potent inhibitor of oral epithelial cell LPS‐induced pro‐inflammatory responses by inducing miRNA regulation of the TLR‐signaling pathway. Triclosan was not a pan‐suppresser of oral epithelial cell responses as β‐defensin 2 [βD2] and βD3 were upregulated by triclosan following LPS‐stimulation.ConclusionsThese data demonstrate both a novel antimicrobial mechanism by which triclosan improves plaque control and an additional anti‐inflammatory property, which could have beneficial effects in periodontal disease resolution.

Universal Metadata Standard

Andrej Poleev

The creation of a next generation internet (semantic web) is impossible without attributes, allowing the semantic association of documents and their integration into information context. To achieve these goals, the Universal Metadata Standard (ums) may be an ultimative tool, which could serve as a basis for documentography, and is functionally required for interpretation of documents by the automatic operating systems.

A Simple Extraction Procedure for Bibliographical Author Field

Pere Constans

A procedure for bibliographic author metadata extraction from scholarly texts is presented. The author segments are identified based on capitalization and line break patterns. Two main author layout templates, which can retrieve from a varied set of title pages, are provided. Additionally, several disambiguating rules are described.
