Summary, etc. <div class="page" title="Page 1"><div class="layoutArea"><div class="column"><p><span>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 </span><span>h </span><span>index – produces many ties, precluding its use to define a full ranking of the authors. In turn, recently, Jorge Hirsch </span><span>proposes the </span><span>h-alpha</span><span> </span><span>index (which measures the number of papers of the </span><span>h </span><span>core in which the author was the scientific leader)and the associated r-alpha </span><span>index(percentage of papers belonging to the </span><span>h </span><span>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 </span><span>h </span><span>index. The method is extremely simple and provides a complete solution to this critical problem of the </span><span>h </span><span>index. To that end, we develop a two steps procedure, which is able to produce a more granulated ranking of the authors. </span></p></div></div></div><br />
