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
SREBP contributes to induction of collagen VI transcription by serum starvation
No full textCollagen VI is a main extracellular matrix protein whose mutation is linked to myopathic diseases. In myoblasts and other cell types, collagen VI gene transcription peaks during cell-cycle exit that precedes differentiation, upon serum withdrawal or confluence. To get insight into this transcriptional regulation, we characterized a growth arrest responsive region (GARR) in the Col6a1 promoter responsible for this effect. In this work, we identify sterol regulatory element binding protein (SREBP) as a GARR binding protein and provide evidence that SREBP contributes to induction of Col6a1 transcription in serum free conditions. Furthermore, our data unveil a previously unexpected link between extracellular matrix production and LDL signalin
Identification of a recognition element for CAAT-enhancer binding proteins (C/EBPs) in the elastin promoter.
No full textDNase I footprinting experiments with a DNA fragment of the human elastin promoter have revealed a protected segment comprised between -156 and -172 nucleotides from the translation start site. Various types of gel retardation experiments indicate that the protected element binds different members of the C/EBP family of transcription factors. CAT (chloramphenicol acetyltransferase) fusion constructs carrying the wild type or a mutated promoter sequence were transfected into NIH3T3 and chick embryo aorta cells. The mutation significantly lowered CAT expression in NIH3T3 cells, but was ineffective in aorta cells. Cotransfection of the CAT promoter constructs with eucaryotic vectors expressing C/EBPs, did not affect the production of the reporter gene in NIH3T3 cells; on the contrary a several-fold increase of CAT activity was observed in aortic cells. This increase, however, was identical for the wild type and the mutated constructs. Taken together the data indicate that the elastin promoter contains a recognition site for proteins of the C/EBP family and that the function of this cis-acting element on basal elastin transcription varies with the cell type
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
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
