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
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
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Varying levels of acceptance and egg abortion of the invasive Halyomorpha halys by different strains of native parasitoids.
No full textThe brown marmorated stink bug Halyomorpha halys (Hemiptera: Pentatomidae) is an invasive pest of global concern affecting many agricultural crops. In the invaded areas (North America, Europe), the impact of native biological control agents is generally low and mostly attributable to generalist species. Native egg parasitoids, for example, often attack H. halys eggs but their offspring are unable to develop. The lack of co-evolved relationships between H. halys and native egg parasitoids could be reduced over time if native egg parasitoids adapt to the new host, either by avoiding them (reducing behavioural acceptance) or by gaining the capacity to successfully exploit them (increasing developmental success). The likelihood of adaptation and consequences for biological control is expected to depend on the amount of within-and among population and species variation in acceptance, host killing ability (egg abortion), and developmental success. The aim of this study was to investigate the level of acceptance, abortion rate and development success of five strains of each of the native North American egg parasitoids Trissolcus euschisti and Telenomus podisi. One-week old mated parasitoid females were exposed to an H. halys eggs clutch at 25 °C. Oviposition behaviour was recorded for 5 hours for each female. Parasitoid emergence was recorded and after the emergence of the nymphs, the unhatched eggs were dissected and classified as aborted, empty, containing nymphs or parasitoids. As expected, all parasitoid strains showed a high (but varying) level of acceptance of H. halys eggs, but offspring development was extremely rare. Varying rates of H. halys egg abortion due to unsuccessful parasitism were also observed, with more abortion in the egg masses exposed to T. podisi compared to those exposed to T. euschisti.
This study will be useful to understand at which level the genetic variance may influence the different adaptation level of egg parasitoids to the new host allowing the development and implementation of further efficacy biocontrol strategies
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
