Evaluating Journal Impact Factor: a systematic survey of the pros and cons, and overview of alternative measures [PDF]

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2020
Background: Journal Impact Factor (JIF) has several intrinsic flaws, which highlight its inability to adequately measure citation distributions or indicate journal quality.

Warped product Einstein metrics on homogeneous spaces and homogeneous Ricci solitons [PDF]

open access: yes, 2013
In this paper we consider connections between Ricci solitons and Einstein metrics on homogeneous spaces. We show that a semi-algebraic Ricci soliton admits an Einstein one-dimensional extension if the soliton derivation can be chosen to be normal.

Geometric thermodynamics: black holes and the meaning of the scalar curvature [PDF]

open access: yes, 2014
In this paper we show that the vanishing of the scalar curvature of Ruppeiner-like metrics does not characterize the ideal gas. Furthermore, we claim through an example that flatness is not a sufficient condition to establish the absence of interactions ...

Using Analog Ensembles with Alternative Metrics for Hindcasting with Multistations

open access: yesParadigmPlus, 2020
This study concerns the problem of making weather predictions for a location where no data is available, using meteorological datasets from nearby stations. The hindcast with multiple stations is performed with different variants of the Analog Ensemble (

Alternative publication metrics in the time of COVID-19

open access: yesBaylor University Medical Center Proceedings, 2021
Alternative metrics are unique bibliometrics comprising social, news, and other sources of media outside of traditional academic citations. Some have suggested that these metrics can complement traditional metrics of research impact, including public engagement with research.

Surface metrics: an alternative to patch metrics for the quantification of landscape structure

open access: yesLandscape Ecology, 2009
Modern landscape ecology is based on the patch mosaic paradigm, in which landscapes are conceptualized and analyzed as mosaics of discrete patches. While this model has been widely success- ful, there are many situations where it is more meaningful to model landscape structure based on continuous rather than discrete spatial heterogeneity.

Tracking citations and altmetrics for research data: Challenges and opportunities [PDF]

open access: yes, 2013
Methods for determining research quality have long been debated but with little lasting agreement on standards, leading to the emergence of alternative metrics.
