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
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
In vitro growth of environmental mastitis pathogens in various bedding materials
Full text linkThe objectives of this study were to evaluate the "bacterial growth promoting properties" of different bedding materials and how these properties are affected by organic matter (addition of sterile urine and feces to mimic environmental conditions). Three environmental mastitis pathogens (Escherichia coli, Klebsiella pneumoniae, Streptococcus uberis) and 10 different sterile bedding materials (straw, pine sawdust, cedar sawdust, chopped petroleum based ink newspaper (CPBIN), chopped soy based ink newspaper (CSBIN), mulched petroleum based ink newspaper, chopped bond paper, sand, pine treated 10 mesh limestone, untreated 10 mesh limestone) were used in 6 trials. Four ml of sterile physiological saline was the liquid source in trials 1-3, whereas 4 ml of a sterile fecal slurry was used in trials 4-6. In trials 1-3, CPBIN and pine sawdust supported significantly lower growth of all organisms at all time periods for all trials. Bacterial numbers in straw and cedar sawdust were significantly lower compared with mulch, bond, and inorganic beddings for 24 h (E. coli) and 36 h (E. pneumoniae-straw only). There were no significant differences among inorganic beddings. Mulch and bond paper supported the greatest numbers of E. coli and E pneumoniae. Cedar sawdust supported significantly lower s. uberis numbers compared with mulch, bond, straw, and inorganic beddings. Numbers of s. uberis were lower than E. coli and K. pneumoniae and declined rapidly after peaking, whereas E. coli and K. pneumoniae numbers generally remained high throughout the trials. In trials 4-6, bacterial numbers (all species) were generally 1-3 logs higher in all beddings for all time periods in all trials. CPBIN and CSBIN supported significantly lower numbers of E. coli and K. pneumoniae (CSBIN only) compared with all other beddings over most time periods. No significant differences occurred among other bedding types. These results demonstrate inherent differences in capacity of different beddings to support bacterial growth in vitro, under sterile conditions, and that organism numbers in bedding are enhanced by organic contamination. Chopped newspaper supported significantly lower numbers of environmental mastitis pathogens with and without the addition of organic matter and may decrease the risk of environmental mastitis. Caution should be exerted when comparing bacterial growth in organic bedding to inorganic bedding since uniform liquid inocula created greater saturation of inorganic beddings because of their greater densities
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
