On using the Shanghai ranking to assess the research performance of university systems
A new look at the Shanghai Jiao Tong Academic Ranking of World Universities to evaluate the performance of whole university systems is taken, with a clear picture emerges: at the aggregate level ARWU seems to be a very reliable one-dimensional scale. Expand
Childbirth Self-Efficacy Inventory: psychometric testing of the Spanish version.
The findings provide an additional and useful insight into practical ways of enhancing a woman's confidence to coping with childbirth: self-efficacy can be strengthened through persuasion by healthcare professionals, childbirth educators, and family and friends who offer support to the pregnant woman.

Growing Gaussian mixtures network for classification applications
The classical EM algorithm for Gaussian mixtures is also extended to jointly include labeled and unlabeled data and the utility of this extension and the reliability of the proposed growing technique are reported. Expand

The paper presents a set of straightforward procedures to estimate raw results and final relative scores and can safely state that the results of the Shanghai academic ranking of world universities are in fact reproducible. Expand
On the effects of institutional size in university classifications: the case of the Shanghai ranking
Primary components analysis of data from the Shanghai ranking (2013 edition) is used to explore factors that contribute to the variation of the total score and concludes that around 30 % of the variation in the ARWU indicators can be attributed to variation in size. Expand
Highly cited researchers: a moving target
The paper traces the development of the HCR category and its use by ARWU, providing insights into the social construction of research indicators and their potential to change research practice. Expand
Measuring the academic reputation through citation networks via PageRank
The approach proposed in this paper may open the door to new, Academic Ranking methodologies that go beyond current methods by reconciling the qualitative evaluation of Academic Prestige with its quantitative measurements via publication impact. Expand
On the internal dynamics of the Shanghai ranking
It is proposed that the utility and usability of the ARWU could be greatly improved by replacing the unwanted dynamical effects of the annual re-scaling based on raw scores of the best performers. Expand
Neural networks in fault detection: a case study
This study is one of the first to include a large set of real vibrational data and to illustrate the potential as well as the limitations of neural networks for fault detection. Expand
Robust stability of complex polynomials with annular uncertainties
In this paper, we find necessary and sufficient conditions for the stability of a family of annular, complex polynomials with the possibility of including a center polynomial. The proposed resultsExpand
