Ready for the energy and water industries: knowledge and skills of business professionals and excecutives: synopsis of the results
Dynamic changes taking place in the energy and water industries are bringing with them new and different demands on business specialists and managers of enterprises. These developments, together with an emerging, demographically induced shortages of specialists call for an industry-focused realignment of academic business education and training. This will require curricula geared to both recent scientific findings in various disciplines and the current and future needs of the energy and water industries for specialists and managers. So far, the latter have hardly been studied systematically. The present study fills this gap

Phylogeny and life history evolution of Blaberoidea (Blattodea)
Blaberoidea, comprised of Ectobiidae and Blaberidae, is the most speciose cockroach clade and exhibits immense variation in life history strategies. We analysed the phylogeny of Blaberoidea using four mitochondrial and three nuclear genes from 99 blaberoid taxa. Blaberoidea (excl. Anaplectidae) and Blaberidae were recovered as monophyletic, but Ectobiidae was not; Attaphilinae is deeply subordinate in Blattellinae and herein abandoned. Our results, together with those from other recent phylogenetic studies, show that the structuring of Blaberoidea in Blaberidae, Pseudophyllodromiidae stat. rev., Ectobiidae stat. rev., Blattellidae stat. rev., and Nyctiboridae stat. rev. (with “ectobiid” subfamilies raised to family rank) represents a sound basis for further development of Blaberoidea systematics. Relationships in Blaberidae are widely incongruent with current classification, but more congruent with geographic distribution, with large Afrotropical, Neotropical, and Indo-Malayan clades. We further investigate evolutionary trends and correlations of various life history traits: wing development, body size, microhabitat, mating pattern, ootheca handling, and clutch size
Using taxonomic consistency with semi‐automated data pre‐processing for high quality DNA barcodes
1. In recent years, large‐scale DNA barcoding campaigns have generated an enormous amount of COI barcodes, which are usually stored in NCBI's GenBank and the official Barcode of Life database (BOLD). BOLD data are generally associated with more detailed and better curated meta‐data, because a great proportion is based on expert‐verified and vouchered material, accessible in public collections. In the course of the initiative German Barcode of Life data were generated for the reference library of 2,846 species of Coleoptera from 13,516 individuals.
2. Confronted with the high effort associated with the identification, verification and data validation, a bioinformatic pipeline, “TaxCI” was developed that (1) identifies taxonomic inconsistencies in a given tree topology (optionally including a reference dataset), (2) discriminates between different cases of incongruence in order to identify contamination or misidentified specimens, (3) graphically marks those cases in the tree, which finally can be checked again and, if needed, corrected or removed from the dataset. For this, “TaxCI” may use DNA‐based species delimitations from other approaches (e.g. mPTP) or may perform implemented threshold‐based clustering.
3. The data‐processing pipeline was tested on a newly generated set of barcodes, using the available BOLD records as a reference. A data revision based on the first run of the TaxCI tool resulted in the second TaxCI analysis in a taxonomic match ratio very similar to the one recorded from the reference set (92% vs. 94%). The revised dataset improved by nearly 20% through this procedure compared to the original, uncorrected one.
4. Overall, the new processing pipeline for DNA barcode data allows for the rapid and easy identification of inconsistencies in large datasets, which can be dealt with before submitting them to public data repositories like BOLD or GenBank. Ultimately, this will increase the quality of submitted data and the speed of data submission, while primarily avoiding the deterioration of the accuracy of the data repositories due to ambiguously identified or contaminated specimens
