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

No full textGram-positive infections are a major burden on patients and healthcare systems globally, and the need to treat these infections correctly in an empirical manner has become paramount. Further complicating this changing etiology is the emergence of resistant strains which are no longer predictably susceptible to standard first-line antimicrobials such as oxacillin or vancomycin. Thus, new agents such as linezolid have been developed to alleviate the 'guesswork' of initial empirical prescribing in infections where Gram-positive pathogens may be present. Future agents also being developed for multiresistant Gram-positive infections include evernimicin antibiotics, daptomycin, oritavancin, glycylcyclines and novel broad-spectrum cephalosporins; however, these are still in the development phase
