Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Neuroblastoma incidence and survival in European children (1978-1997): Report from the Automated Childhood Cancer Information System project.
No full textAbstract
The Automated Childhood Cancer Information System (ACCIS) collects and presents data on childhood cancer in Europe. This report describes trends (1978-1997) and geographical differences (1988-1997) in incidence and survival for 6202 children with neuroblastoma from 59 registries in 19 countries, grouped into five regions (British Isles, West, East, North, and South). The age-standardised incidence rate (ASR) of neuroblastoma in Europe in 1988-1997 was 10.9 cases per million children, being highest in infants (52.6). The ASR of neuroblastoma increased in Europe from 8.4 in 1978-1982 to 11.6 in 1993-1997, mostly due to an increase in infants (from 35.4 to 57.8). Overall 5-year survival was 59%, ranging from 47% (East) to 67% (West). It improved markedly from 37% in 1978-1982 to 66% in 1993-1997, especially in infants. A certain amount of overdiagnosis in children under 2 years of age may explain the increased incidence rates and partially the increase in survival. Survival of older children (aged 2-14 years), which is likely to be largely affected by therapy, has also improved from 21% to 45%
Time trends of cancer incidence in European children (1978-1997): Report from the Automated Childhood Cancer Information System project
No full textWithin the framework of the Automated Childhood Cancer Information System (ACCIS), time trend analyses for childhood cancer were performed using data from 33 population-based cancer registries in 15 European countries for the period 1978-1997. The overall incidence rate based on 77,111 cases has increased significantly (P<0.0001), with an average annual percentage change (AAPC) of 1.1%. The rising trend was observed in all five geographical regions and in the majority of the disease groups (in order of AAPC): soft tissue sarcomas (1.8%), brain tumours, tumours of the sympathetic nervous system, germ-cell tumours, carcinomas, lymphomas, renal tumours, and leukaemias (0.6%). No change was seen in incidence of bone tumours, hepatic tumours and retinoblastoma. The increased incidence can only partly be explained by changes in diagnostic methods and by registration artefacts. The patterns and magnitude of these increases suggest that other factors, e.g. changes in lifestyle and in exposure to a variety of agents, have contributed to the increase in childhood cancer in the recent decades
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
