Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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

Raffield Benjamin Paul, Inside that fortress sat a few peasant men, and it was half-made: a study of 'Viking' fortifications in the British Isles, AD793-1066, Thèse de doctorat soutenue en 2010, (Université de Birmingham) Résumé/abstract : The study of Viking fortifications is a neglected subject which could reveal much to archaeologists about the Viking way of life. The popular representation of these Scandinavian seafarers is often as drunken, bloodthirsty heathens who rampaged across Brita..
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
Neopolyploid establishment and evolution /by Benjamin Paul Oswald.
Despite the well-documented historical importance of polyploidy, the mechanisms responsible for the establishment and evolutionary success of novel polyploid lineages remain unresolved. One possibility, which has not been previously evaluated theoretically, is that novel polyploid lineages are initially more resistant to pathogens than the diploid progenitor species. Another possibility is that polyploidization results in immediate divergence of phenotypic characters, and may alter the phenotypic and genotypic associations between traits, i.e. the P and G matrices. In combination with factors such as competition, assortative mating, reproductive assurance, and stabilizing selection, establishment and coexistence may be plausible. Here we explore neopolyploid establishment and evolution in three ways: (1) by developing and analyzing mathematical models of interactions between newly formed polyploid lineages and their pathogens; (2) by studying the perennial plant Heuchera grossulariifolia and measuring phenotypic divergence and changes in the phenotypic and genotypic covariance matrices caused by neopolyploidization; and (3) by developing a model of polyploid establishment using individual based simulations that explores how changing environments facilitate polyploid evolution. We find, that for the genetic mechanisms of pathogen resistance with the best empirical support, newly formed polyploid populations of hosts are expected to be more resistant than their diploid progenitors. Our results also reveal that polyploidization causes immediate divergence for traits relevant to establishment and results in significant changes in the structure of the phenotypic covariance matrix. In contrast, our results do not provide evidence that polyploidization results in immediate and substantial shifts in the genetic covariance matrix. Our model shows that polyploid establishment and coexistence with diploids is likely using observed values for parameters, and without the polyploid lineage needing a fitness advantage. We further predict that polyploid lineages will have an increased opportunity for replacement of their diploid progenitors in cases where the environment changes rapidly.Thesis (Ph.

Dispelling the Myths Behind First-author Citation Counts
We 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
