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
Learning from errors in radiology: a comprehensive review
No full textAn important goal of error analysis is to create processes aimed at reducing or preventing the occurrence of errors and minimizing the degree of harm. The discovery of any errors presents an opportunity to study the types that occur and to examine their sources and develop measures to prevent them from recurring. The development of an effective system for detecting and appropriately managing errors is essential to substantially attenuate their consequences. At this stage, the error analysis process identifies contributing factors to enable the implementation of concrete steps to prevent such errors from occurring in the future. Active and comprehensive management of errors and adverse events requires ongoing surveillance processes. Educational programs, morbidity and mortality meetings, and a comprehensive and respected root cause analysis process are also essential components of this comprehensive approach. To reduce the incidence of errors, health care providers must identify their causes, devise solutions, and measure the success of improvement efforts. Moreover, accurate measurements of the incidence of error, based on clear and consistent definitions, are essential prerequisites for effective action
