The Carbon_h-factor: predicting individuals' research impact at early stages ...
Assessing an individual's research impact on the basis of a transparent algorithm is an important task for evaluation and comparison purposes. Besides simple but also inaccurate... -
Why Has the Number of Scientific Retractions Increased?
Background The number of retracted scientific publications has risen sharply, but it is unclear whether this reflects an increase in publication of flawed articles or an... -
A Comprehensive Survey of Retracted Articles from the Scholarly Literature
Background The number of retracted scholarly articles has risen precipitously in recent years. Past surveys of the retracted literature each limited their scope to articles in... -
Impact of Reporting Bias in Network Meta-Analysis of Antidepressant Placebo-C...
Background Indirect comparisons of competing treatments by network meta-analysis (NMA) are increasingly in use. Reporting bias has received little attention in this context.... -
Using Crowdsourcing to Evaluate Published Scientific Literature: Methods and ...
Systematically evaluating scientific literature is a time consuming endeavor that requires hours of coding and rating. Here, we describe a method to distribute these tasks... -
Profit (p)-Index: The Degree to Which Authors Profit from Co-Authors
Current metrics for estimating a scientist’s academic performance treat the author’s publications as if these were solely attributable to the author. However, this approach... -
The impact of funding through the RF President's grants for young scientists ...
The impact of grants on research productivity has been investigated by a number of retrospective studies. The results of these studies vary considerably. The objective of my... -
Predicting Scholars' Scientific Impact
We tested the underlying assumption that citation counts are reliable predictors of future success, analyzing complete citation data on the careers of ~150,000 scientists. Our... -
Measuring the Value of Research Data: A Citation Analysis of Oceanographic Da...
Evaluation of scientific research is becoming increasingly reliant on publication-based bibliometric indicators, which may result in the devaluation of other scientific... -
Do Altmetrics Work? Twitter and Ten Other Social Web Services
Altmetric measurements derived from the social web are increasingly advocated and used as early indicators of article impact and usefulness. Nevertheless, there is a lack of... -
A New Family of Cumulative Indexes for Measuring Scientific Performance
In this paper we propose a new family of cumulative indexes for measuring scientific performance which can be applied to many metrics, including h index and its variants (here... -
A Measure of Total Research Impact Independent of Time and Discipline
Authorship and citation practices evolve with time and differ by academic discipline. As such, indicators of research productivity based on citation records are naturally... -
Universities scale like cities.
Recent studies of urban scaling show that important socioeconomic city characteristics such as wealth and innovation capacity exhibit a nonlinear, particularly a power law... -
Impact of GDP, spending on RD, number of universities and scientific journals...

Bibliometric Evidence for a Hierarchy of the Sciences
The hypothesis of a Hierarchy of the Sciences, first formulated in the 19(th) century, predicts that, moving from simple and general phenomena (e.g. particle dynamics) to... -
Database citation in full text biomedical articles.
Molecular biology and literature databases represent essential infrastructure for life science research. Effective integration of these data resources requires that there are... -
The number of scholarly documents on the public web.
The number of scholarly documents available on the web is estimated using capture/recapture methods by studying the coverage of two major academic search engines: Google Scholar... -
Network Effects on Scientific Collaborations
Background: The analysis of co-authorship network aims at exploring the impact of network structure on the outcome of scientific collaborations and research publications.... -
A simple index for the high-citation tail of citation distribution to quantif...
BACKGROUND: Conventional scientometric predictors of research performance such as the number of papers, citations, and papers in the top 1% of highly cited papers cannot be... -
Trends in Citations to Books on Epidemiological and Statistical Methods in th...
BackgroundThere are no analyses of citations to books on epidemiological and statistical methods in the biomedical literature. Such analyses may shed light on how concepts and...
