Editorial notice on the review process 

As part of our ongoing effort to safeguard the scientific quality of our journal, the editorial board detected administrative shortcomings in the review procedure for two 2014 issues and one 2015 issue. As a result of this administrative deficiency we were unable to trace the authors of some review reports. 

In order to remedy this shortcoming the editorial board and the publisher decided to re-evaluate all concerned articles by anonymous external reviewers. The review confirmed that all published articles met academic standards. At the same time, we have adjusted our administrative review procedures in order to avoid similar incidents in the future. Unfortunately, this resulted in a delay of our publication scheme for the second and third issue of 2015. We would like to express our sincere apologies to our authors and readers.
