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
Variations on the Author
Full text link“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
A geographic correlation study of the incidence of pancreatic and other cancers in whites
No full textEcologic analyses of cancer incidence rates may be helpful to formulate hypotheses on risk factors and mechanisms of poorly known neoplasms, such as pancreatic cancer. We calculated sex-specific pair-wise and partial (after adjustment for lung cancer incidence) correlations between the incidence of pancreatic cancer and that of 23 other cancers in two international sets of cancer incidence data: the recorded or estimated incidence for 2000 in 38 European countries and the recorded incidence in Whites for 1993-1997 in 35 cancer registries from North America and Oceania. In both sexes and datasets, a strong, highly significant correlation was present between the incidence of pancreatic cancer and that of lung and kidney cancer. For the latter, correlation coefficients in the European data were 0.71 in men and 0.74 in women (both p<0.0001); in the cancer registry data they were 0.57 (p=0.0004) in men and 0.45 (p=0.007) in women. The results on kidney cancer were not modified by adjustment for the correlation with lung cancer, were confirmed by the application of spatial regression models and, with the exception of men in the cancer registry data, were confirmed in sensitivity analyses restricted to the populations with data of best quality. Weaker, less consistent correlations were found for colorectal, endometrial, ovarian and bladder cancers. Tobacco smoking is a plausible explanation of the association between pancreatic and lung cancer; the association with kidney cancer likely reflects additional common etiologic and pathogenetic factors of the two neoplasms. © Springer 2006
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Mechanistic considerations in the molecular epidemiology of head and neck cancer
No full textHead and neck cancer occurs through a complex multistage process that is likely to involve a combination of carcinogen exposure and genetic susceptibility. The primary cause of head and neck cancer are alcohol consumption and cigarette smoking, although the carcinogenic mechanism for these agents is unclear. Molecular epidemiological studies of head and neck cancer can help to clarify the carcinogenic process in several ways, including identification of metabolizing genes which increase the risk of head and neck cancer, identification of DNA adducts in target cells and analysis of specific gene mutations and their relationship with exposure. This review summarizes current knowledge on the molecular epidemiology of head and neck cancer and attempts to identify those areas where future studies may prove fruitful
