Catching the Changing-Look AGN Mrk 1018 as it undergoes another Significant Change in Accretion Rate
No full textOne joint Chandra/HST ToO observation (50 ks/3 orbits each) is proposed of the changing-look AGN Mrk 1018. This is to be triggered if the optical flux increases/decreases by at least a factor of two compared to the highest/lowest optical flux seen over the period 2016-2020. The major outburst in summer 2020 indicates that Mrk 1018 is still dynamic and unpredictable. Chandra data will be used to study how the X-ray emitting corona responds to another change in the accretion rate, whereas joint UV data are needed to study the X-ray corona/UV accretion disk connection during a major reconfiguration of the system. In addition, the HST data will check whether the UV outflow discovered in 2016 is directly linked to Mrk 1018's significant drop in luminosity
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
Lack of IDR-1018 toxicity.
No full text<p>The effects of IDR-1018, LL-37 and HB-107 on viability/metabolic activity were determined using an MTT-Assay with HaCaT cells (left) and primary human fibroblasts (HFB; right) at the indicated concentrations. Cells were incubated with peptides for 24 hours. Standard deviation was calculated out of three independent experiments and assessed as SEM (Statistical significance IDR-1018 vs. LL-37: * = p<0.05; ** = p<0.01; *** = p<0.005; IDR-1018 vs. HB-107<sup>+</sup> = p<0.05).</p
