AMG 837 Potentiates Insulin Secretion from Islets.
No full text<p>Islets were isolated from mice and the activity of AMG 837 on insulin secretion was determined. (A) The dose response relationship of AMG 837 and insulin secretion on mouse islets at 16.7 mM glucose was evaluated. (B) In order to determine whether the activity of AMG 837 was GPR40/FFA1 dependent, islets were isolated from GPR40 null mice (<i>gpr40<sup>−/−</sup></i>). AMG 837 potentiated glucose stimulated insulin secretion from wild type islets (black bar), but not <i>gpr40<sup>−/−</sup></i> islets (blue bar). (C) Glucose dependence of AMG 837 on glucose stimulated insulin secretion was determined by incubating islets in buffer containing either 0.1% DMSO (black bar) or 1 µM AMG 837 in 0.1% DMSO (blue bar) in the presence of increasing concentrations of glucose. Statistical significance is denoted by * (p<0.5), ** (p<0.01) and *** (p<0.001) as determined by one-way or two-way ANOVA.</p

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
International Telecommunication Union-Radiocommunication Sector (ITU-R) P.837-6 and P.837-7 performance to estimate Indonesian rainfall
No full textThis work evaluated the performance of International Telecommunication
Union-Radiocommunication Sector (ITU-R) P.837-6 and P.837-7 models
(Annex 1) to estimate one-minute rainfall rates in Indonesia. In addition
to the default ITU-R P.837-6, the input of ITU-R P.837-6 is also
modified using data which has better spatial resolution, i.e. a combination
of Tropical Rainfall Measuring Mission (TRMM) 3A25 and 3B43
(ITU-R+3A25+3B43), 3B42 and 3B43 (ITU-R+3B42+3B43), Global
Satellite Mapping of Precipitation (ITU-R+GSMaP), and Global
Precipitation Measurement (ITU-R+GPM). Among the five test sites,
the default ITU-R P.837-6 and ITU-R+3A25+3B43 could predict one-minute
rainfall rates at two locations accurately. The ITU-R P.837-7 exhibited
a marginally better performance for sites that had a high percentage of very
heavy rain, particularly at large (1%) and small (0.001%) percentages of time
exceeded. The spatial distribution of rainfall rate produced by ITU-R P.837-7
and ITU-R+3A25+3B43 was closer to the pattern demonstrated by recent
satellite precipitation measurements
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
