    "Modulares Tumorendoprothesensystem für die Untere Extremität KMFTR"

    206 patients with tumorendoprosteses of the KMFTR-type at the lower extremity were operated at the Institute Rizolli Bologna and at the University Clinic of Vienna. The minimum follow up was 2 years (mean 3.2, max. 8 years). In order to bridge the defect caused by tumor resection the proximal femur was replaced in 42 cases, the distal femur in 119 cases and in 6 patients a total femur prosthesis was used. The proximal tibia was replaced in 35 cases and in 4 cases a total knee prosthesis was implanted. Clinical evaluation according to Enneking revealed 71.6% excellent and good results. In 83.4% the radiological score was higher then 20. We saw deep infections in 8.2% (17 patients), breakage of the prosthesis in 6.8% and aseptic loosening in 5.8%. 3 patients had to be amputated due to infection. In the remaining cases of infection in 66% of the patients healing was observed. All cases of aseptic loosening or breakage could be revised successfully by an exchange of the prostheses and therefore salvage of the leg was achieved

    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

    Appropriate Similarity Measures for Author Cocitation Analysis

    No full text
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
