Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Full text linkThe yellow mealworm beetle Tenebrio molitor L. (Coleoptera Tenebrionidae) is an important stored products pest, although its
larvae are also one of the most promising for food and feed. Although T. molitor has been widely investigated, there remains a
lack of information about the sensory structures on maxillary and labial palps. Here, it was investigated the external morphology
and distribution pattern of the sensilla on mouthpart palps of T. molitor larvae using scanning electron microscopy. In T. molitor,
the maxillary palp has three segments, whereas the labial palp has two segments. Based on the morphology of the features of the
sensilla on the apical articles of both the maxillary and labial palps, we classified them into nine types: sensilla trichoidea types 1
and 2, sensilla digitiformia, sensilla chaetica, sensilla coeloconica, sensilla basiconica types 1 and 2, sensilla styloconica types 1
and 2. A total of 23 sensilla on maxillary palps and 13 sensilla on labial palps were found. In particular, the sensilla basiconica
form the sensory complex located on the tip of each palp. In T. molitor, the numbers of sensilla present on the sensory complexes
do not differ between maxillary and labial palps, as 13 units
