Una nuova tecnica per la misurazione dell’autofluorescenza del fondo oculare: modulo software per l’analisi quantitativa dell’autofluorescenza del fondo oculare
No full textA new method of autofluorescence quantification: software module autofluorescence quantitative analysis. Age related macular disease (AMD) is now the leading cause of severe visual loss in all industrialized countries. It may be speculated that changes seen in FAF imaging on the RPE cell level precede the occurrence of visible lesions as the disease progresses. There is no an universally accepted standard method to quantification FAF. It should be remembered that AF measurements are relative and subject to degradation by the lens, rather than absolute values obtained spectroscopically. To make quantitative assessment of abnormal AF we planed a new method based on the quantification of grey variations between two images of AF, recorded in different period, in the same patients. Key words: autofluorescence quantification, age-related macular degeneratio
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
