Wiegman and Shappel (26) described years ago a practical and comprehensive model of human factors which can be applied to every accident. The so named HFACS or Human factors Accident Classification System model followed the causative models described by previously by Reason (17) and later by AGARD WG-23 (19). Nowdays it constitues a handy taxonomical tool to identify and determine causal facts ...

We invoke concepts from the theory of hypergraphs to give a measure of the closeness of family resemblance, and to make precise the idea of a composite likeness. It is shown that for any positive integer m, for any general term possessing any extent of family resemblance strictly greater than m, there is a taxonomical representation of the term whereby each subordinate taxon has an extent of fa...

Nine new species of the genus Folsomia are described from Buryatia (Russia, East Siberia): F. biparis sp. nov., F. fumosa sp. nov., F. heterothorax sp. nov., F. maximovi sp. nov., F. pseudovtorovi sp. nov., F. sensivillosa sp. nov., F. uniparis sp. nov., F. uniramia sp. nov., and F. vitimica sp. nov. A complete list and a key to species recorded in the Buryatia are given, and their morphology, ...

The identification of parasites in tissue sections is often difficult and fresh specimens are always required for accurate taxonomical classification. However, histological sections are in many cases the only material available and the identification of parasites in sections the subject of the recent histopathology workshop held in Dublin. The group reviewed the characteristics of representativ...

Based on the revision of available literature on the Colombian Cladocera (Crustacea: Branchiopoda), we present an annotated checklist, with taxonomical comments for all taxa recorded since the start of research on this group in the country in 1913. We have listed 101 valid taxa, of which most records belong to the Caribbean region of Colombia. The situation in Colombian Cladocera taxonomy is, a...

Authors’ contributions KMCR performed the field data collection and wrote the first original manuscript in Portuguese (Master’s thesis), CGZ prepared the submission version of the manuscript and carried the taxonomical identifications demanded, LCSL coordinated the research project, performed the original analysis, advised and mentored the original manuscript (Ms. KMCR Master’s thesis), RRNA de...

— Service discovery is one of the key problems that has been widely researched in the area of Service Oriented Architecture (SOA) based systems. Service category learning is a technique for efficiently facilitating service discovery. Most approaches for service category learning are based on suitable similarity distance measures using thresholds. Threshold selection is essentially difficult and...
