    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Mechanical Fasteners for Cladding Sandwich Panels: Interpretative Models for Shear Behaviour

    No full text
    The shear performance of screwed connection systems usually adopted for lightweight sandwich panels is investigated in this paper. First of all, after brief considerations concerning the possibility to use cladding panels as diaphragm in steel building and the corresponding connecting system requirements, the results of available monotonic and cyclic experimental analyses on several connection typologies are summarised. Then mathematical models able to interpret both monotonic and cyclic behaviour of the connections are proposed. In particular, the mathematical cyclic model is based on the previously defined envelope curve, which is expressed by means of a Ramberg-Osgood type law relationship and calibrated trough monotonic tests. Finally, the comparison between experimental and numerical results is carried out, focussing on the actual dissipative capacities of such connection typologies
