BETWEEN THE COURT AND THE BATTLEFIELD: SAMURAI WOMEN IN THE TALE OF THE HEIKE
Full text linkThe Heike monogatari (the Tale of the Heike, fourteenth century) recounts the fall of the Heike, a military clan also known as Taira, at the end of the Genpei War (1180-1185). In it, there are features dozens of female characters. This essay examines the representation of a number of women of warrior backgrounds in the Heike monogatari. The aim is to present the sense of the world of the Heike women, their relationship with other characters, male and female, and their function in the story
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
Molecular mechanisms and new therapeutic targets in epithelial to mesenchymal transition (EMT) and fibrosis, volume II
No full textThe induction of inflammatory epithelial-mesenchymal transition (EMT)/fibrosis requires a complex cellular reprogramming process involving epithelial, stromal, and immune cells and has important implications on cell survival, plasticity, and migratory/invasive abilities.
A wide array of extracellular stimuli, including soluble mediators, cell-to-cell interactions, and binding to the extracellular matrix (ECM), drive changes in resident cells towards a mesenchymal-like/profibrotic phenotype.
The classical EMT/fibrosis pathways induced by transforming growth factor (TGF)-β, the central profibrotic mediator, as well as by tumor necrosis factor (TNF)α and epidermal growth factor (EGF) are well known. Here we focused on the roles of new intracellular mechanisms involved in the modulation of EMT/fibrosis. Moreover, a better understanding of the crosstalk between classical EMT/fibrosis pathways and stress signaling pathways, such as autophagy and unfolded protein response (UPR) become increasingly important in the field.
Epigenetic processes, including histone acetylation and DNA/histone methylation, were shown to be essential modulators of the persistence of a new mesenchymal-like state or the reversion to an epithelial-like phenotype. Recent single-cell RNA-sequencing (scRNA-seq) experiments revealed that EMT transition is a transcriptional continuum of numerous epithelial-mesenchymal states rather than a binary epithelial vs. mesenchymal model. These recent insights considerably enhanced the understanding of the complexity and cell-specificity of this essential physio-pathological process.
However, despite considerable efforts in the field, new mechanisms remain to be elucidated, and cell-type specificities have yet to be fully characterized.
In this Research Topic, Sara Lovisa provided an updated overview of the recent debate on the definition of EMT, analyzing the impact of new technologies such as single cell transcriptomics. Moreover, the author summarized the different strategies used to define EMT in fibrotic disorders
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
