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

No full textVariations 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
Effects of loading method and crate position on the truck on some stress indicators in rabbits transported to the slaughterhouse
No full textThe aim of this study was to determine the effects of loading method and crate position on the truck onsome stress indicators in commercial rabbits transported to the slaughterhouse. On two journeys inJuly a total of 192 animals (82 days old) were transported to the slaughterhouse during the morning(9.00 a.m.) for a mean transport time of 100 min. The transport truck was uncovered, with a total of128 fixed plastic transport crates, for an overall capacity of 1500 subjects. To evaluate the effects ofcrate position, at each session, 96 animals were distributed at random in 8 crates on the same side ofthe truck (12 animals per cage, 57.7 kg/m2) as follows: 24 animals in 2 top front (TF) crates, 24animals in 2 bottom front (BF) crates, 24 in 2 top rear (TR) crates and 24 in 2 bottom rear (BR) crates.In the middle of TF, BF, TR and BR crates four data-loggers were placed for temperature (T°) andrelative humidity (%RH) control. To evaluate different loading methods one cage from each positionwas loaded in a smooth way (S: 12 rabbits from the farm crates were placed in a wide trolley andcarried gently into the transport cage - loading time for 48 subjects: 12 min.) while the other wasloaded in a rough way (R: rabbits from four crates were carried all together in the same trolley andloaded hurriedly - loading time for 48 subjects: 4 min.). All rabbits were individually weighed beforetransport and at unloading. To assess some stress indicators, blood samples were collected from 40male rabbits (20 per journey: 5 per truck position, 10 per loading method) on the farm 2 days beforeloading (basal level) and at slaughter during exsanguinations. The TR crates showed the highest meantemperature and the lowest relative humidity (P<0.001) while the other cages on the truck differedonly in humidity. No effects on weight losses during transport could be ascribed to loading methods orcrate position in the truck. Corticosterone showed a tendency to increase from basal levels in allanimals, the increase being significant only during transport using the rough loading method.Neutrophilia and lymphocitopenia were significant for all rabbits, independently of their position inthe truck or the loading method. Packed cell volume never differed significantly among groups.Rabbits transported in TR crates (with higher mean temperature) showed a significant augmentation oftotal protein level, as a possible consequence of dehydration. A significant upsurge of aspartate aminotransferase and creatine kinase activities was observed in all the animals. In conclusion, stressparameters were more influenced by transport and handling itself rather than by specific conditionsrelated to different loading methods or crate position in the truck.[...
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
