Despite the drawbacks already pointed out and the wide set of variants suggested to overcome some of them, the ℎ-index is the most used measure to conduct the author-level scientific evaluation. Simplicity is probably its main advantage and the reason for its popularity. The main goal of the current study is to propose an index that is directly linked and almost perfectly correlated with the ℎ-index but is even simpler to obtain. Our index does not require any form of calculation. It disregards the distribution of citations among the papers of the author. Instead, only the total number of papers and the total number of citations of the author is used to obtain the final score. The score of each author can be seen in the table we present in this study. Although much simpler than the ℎ-index (and other measures that account for citation distribution), our index produces the same general conclusions. We illustrate the application of this index with a sample of economists. info:eu-repo/semantics/publishedVersion

The measurement of scientific performance is usually done giving the full credit of each paper to all its authors. Aiming to analyze the impact of the number of authors on the performance, we propose an adjustment to the h-index that is flexible enough to allow the consideration of distinct co-authorship weighting schemes. We then evaluate the publication performance of the members of the departments of economics of the top 10 world universities. Our results show that the number of authors per paper is rapidly increasing and that this dimension measurably affects the final ranking of authors even in a subject area where the average number of authors is lower than in physical and life sciences. info:eu-repo/semantics/publishedVersion

For many decisions in science, evaluators have to select, assess, and rank authors based on their scientific achievements. However, the most diffused scientific performance bibliometric metric – the h index – produces many ties, precluding its use to define a full ranking of the authors. In turn, recently, Jorge Hirsch1 proposes the ℎɑ index (which measures the number of papers of the h core in which the author was the scientific leader)and the associated rɑ index(percentage of papers belonging to the h core in which the author was leader)to capture the concept of scientific leadership. We suggest using this last measure to break the ties of the h index. The method is extremely simple and provides a complete solution to this critical problem of the h index. To that end, we develop a two steps procedure, which is able to produce a more granulated ranking of the authors. info:eu-repo/semantics/publishedVersion

Num cenário de crescente abertura das economias, com acentuado incremento dos níveis de globalização económica, os países (e as empresas) enfrentam forte concorrência nos mercados internacionais. Apesar da importância deste fenómeno, as métricas dominantes para a análise desta temática são ainda demasiado simplistas para captar a complexidade do fenómeno. No entanto, na última década, emergiram alguns contributos que contribuíram para minimizar este gap da literatura. O objetivo deste artigo é triplo. Em primeiro lugar, discutir criticamente esses contributos recentes. Em segundo lugar, contribuir para estruturar as diferentes formas de avaliação do fenómeno da concorrência comercial. Em terceiro lugar, identificar lacunas existentes, sugerindo pistas de investigação. info:eu-repo/semantics/publishedVersion

In universities and other research institutions, critical decisions (e.g., hiring, promotions, awards, and research funds allocation) are supported by bibliometric measures. The present study contributes to the literature by proposing a measure of publication performance. Our index (p'-index) takes the p-index suggested by Prathap (2010a,b) as starting point. With a small adjustment in the p-index, we obtain a measure that does not require any form of calculations. We build a table (presented in this study as online appendix) showing the final performance scores for each combination of: (i) total number of papers and (ii) total number of citations. The evidence shows that this new metric is almost perfectly correlated with the p-index (0.999), meaning that we can reach the same conclusions without having to make calculations. info:eu-repo/semantics/publishedVersion

Pontoscolex corethrurus (Müller, 1857) plays an important role in tropical soil ecosystems and has been widely used as an animal model for a large variety of ecological studies, in particular due to its common presence and generally high abundance in human-disturbed tropical soils. In this study we describe the complete mitochondrial genome of the peregrine earthworm P. corethrurus. This is the first record of a mitochondrial genome within the Rhinodrilidae family. Its mitochondrial genome is 14 835 bp in length containing 37 genes (13 protein-coding genes (PCG), 2 rRNA genes and 22 tRNA genes). It has the same gene content and structure as in other sequenced earthworms, but unusual among invertebrates it has several overlapping open reading frames. All genes are encoded on the same strand. Most of the PCGs use ATG as the start codon except for ND3, which uses GTG as the start codon. The A+T content of the mitochondrial genome is 59.9% (31.8% A, 28.1% T, 14.6% G, and 25.6% for C). The annotated genome sequence has been deposited in GenBank under the accession number KT988053. Made available in DSpace on 2017-09-30T10:26:30Z (GMT).

Urban flooding events which are often caused by a lack of capacity of the urban collecting system, can be a risk to human life. The CENTAUR project is developing an innovative, cost effective, local and autonomous sewer flow control system to reduce urban flood risk. The CENTAUR system consists of a flow control device controlled by a Fuzzy Logic algorithm to allow upstream storage capacity to be used to reduce downstream flood risk. Results will be presented from a modelling study of this system, based on the sewer network in the city of Coimbra, Portugal. These results show the ability of the system to decrease water level in a critical location, without increasing flood risk upstream. CENTAUR is an Innovation action funded by European Union’s (EU) Horizon 2020 research and innovation programme under grant agreement No 641931.
