Suicidal behaviour and somatic disorders
No full textUdgivelsesdato: Feb-11AIM: To review current knowledge on suicide and suicidal behaviour in selected somatic disorders and pain syndromes. MATERIALS AND METHODS: Available literature concerning suicide risk and cancer, neurological disorders, heart and lung disorders, bowel disorders. AIDS: Rheumatoid arthritis and pain was found by using Medline. RESULTS: There are fairly robust studies on the increased risk of suicide in a number of neurological disorders and cancers, while studies in cardiac, lung, rheumatologic disorders and others are fewer and far less robust. CONCLUSION: Suicide risk factors i.e. psychiatric disorder, previous suicide attempts, suicidal thoughts have to be considered in patients suffering from somatic disorders, especially disorders involved with an increased suicide risk
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
