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
Non-LTE modelling of prominence fine structures using hydrogen Lyman-line profiles
Date of Acceptance: 10/03/2015Aims. We perform a detailed statistical analysis of the spectral Lyman-line observations of the quiescent prominence observed on May 18, 2005. Methods. We used a profile-to-profile comparison of the synthetic Lyman spectra obtained by 2D single-thread prominence fine-structure model as a starting point for a full statistical analysis of the observed Lyman spectra. We employed 2D multi-thread fine-structure models with random positions and line-of-sight velocities of each thread to obtain a statistically significant set of synthetic Lyman-line profiles. We used for the first time multi-thread models composed of non-identical threads and viewed at line-of-sight angles different from perpendicular to the magnetic field. Results. We investigated the plasma properties of the prominence observed with the SoHO/SUMER spectrograph on May 18, 2005 by comparing the histograms of three statistical parameters characterizing the properties of the synthetic and observed line profiles. In this way, the integrated intensity, Lyman decrement ratio, and the ratio of intensity at the central reversal to the average intensity of peaks provided insight into the column mass and the central temperature of the prominence fine structures.Peer reviewe
Remaking intimate citizenship in multicultural Europe: introduction
Book synopsis: This book offers a ground-breaking analysis of how women's movements have been remaking citizenship in multicultural Europe. Presenting the findings of a large scale, multi-disciplinary, cross-national feminist research project, FEMCIT, it develops an expanded, multi-dimensional understanding of citizenship as practice and experience. Remaking Citizenship pays particular attention to processes of racialization and minoritization as they impact upon, and construct, citizenship and women's movements in contemporary Europe. The book develops answers to two vital questions – what difference have women's movements and feminism made to experiences and practices of citizenship, and how can we assess the state of citizenship in contemporary Europe from the perspective of women, particularly minoritized women

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
Lamentation sur Sumer et Ur 351
La ligne 351 de LSU soulève des problèmes considérables. La version de Nippur (G et K) a TUR(-)sag̃ (dumu-sag̃) bulug-ga KI.LAM-bi-a ki [...], celle d'Ur (HH) dul2-sag̃ bulug-ga KI.LAMba-bi-a ki li-bi-ib-de5-de5-ge. S.N. Kramer ne traduit pas (ANET [1969] 617). P. Michalowski, s'appuyant sur le texte d'Ur, reconstruit túl sag bulug-ga ganba-bi-a ki li-bi-ib-ri-ir-ge (The Lamentation over the Destruction of Sumer and Ur [=MC 1, 1989] 58) et propose "The one who (used to) drill large wells, (now just) scratches the ground in the market place" (p. 59). Dans son commentaire (p.98), il remarque toutefois que les deux textes de Nippur ont TUR sag au lie de dul2-sag̃ et n'exclut pas que "the phonetic similarity between túl and tur result[s] in a reinterpretation of the beginninge of the line as dumu sag". Le PSD (B 176) enfin enregistre le passage s.v. bulug B (a word for son), li dumu-sag̃, mais n'offre pas de traduction
Role of the vertical pressure gradient in wave boundary layers
The pressure field in an oscillatory boundary layer is obtained by means of direct numerical simulations (DNS). The vertical pressure gradient is treated as any other turbulence quantity and its statistical properties are calculated from the DNS data. Moreover, a criterion involving the vertical pressure gradient is used to detect spots. The large fluctuations of the vertical pressure gradient, which take place in the turbulent flow, have significant implications for sediment transport
Dynamics of chromospheric and transition region lines observed with SOHO/SUMER and the GCT/Tenerife
High-resolution spectroscopic observations of the quiet Sun have been carried out in September 1996 at the German Gregory Coude Telescope (GCT) in Tenerife and in May 1997 with the SUMER instrument onboard SOHO. Time sequences of spectra in the visible and near infrared as well as in the ultraviolet have been taken, covering a range of heights from the solar photosphere up into the transition region. In this contribution we present the dynamical behaviour observed at the various heights in the solar atmosphere. (C) 2000 COSPAR. Published by Elsevier Science Ltd
