Gedichten Ali Rashid Moussaoui
No full textSchilder en dichter Ali Rashid probeert in zijn werk een verbinding te maken tussen persoonlijke herinneringen en de loop van de algemene geschiedenis. Herinneringen aan Irak, de mensen daar, zijn jeugd, de oorlogsjaren, de onderdrukking en de armoede. Door zijn herinneringen als uitgangspunt te nemen en ze in een breder perspectief te plaatsen, probeert hij als kunstenaar verantwoordelijkheid te nemen voor de hem omringende wereld. Tijdens zijn verblijf in Nederland zoekt hij naar verbanden tussen het Oosten en het Westen. Zijn werk is krachtig, maar ook poëtisch. Als schilder en dichter zoekt hij naar manieren om lijnen en letters te verenigen. Deze fascinatie stamt uit de oorlogsjaren toen gedichten onleesbaar werden gemaakt door er doorheen te tekenen. Een zaak van leven en dood
Influence of Ti–TiN multilayer PVD-coatings design on residual stresses and adhesion
Get PDFMultilayer systems can offer an efficient way of controlling residual stress, improve adhesion and enhance toughness of coated systems. This work aims at the development of multilayer coating with improved adhesion, based on numerical design approach. The numerical model of titanium-titanium nitride (Ti-TiN) multilayer has been formulated with multi-physics FEM, to find the optimal thickness of individual layers in a multilayer that can decrease interfacial axial and in-plane shear stress. These coatings configurations are experimentally produced to quantitatively evaluate the scratch adhesion, in-plane residual stresses, nanoindentation hardness and elastic-modulus. Analytical modeling with FilmDoctor® was performed for accurate adhesion evaluation. The multilayer in comparison with bi-layer shows significant improvement (22%) in adhesion under decreased interfacial stress conditions without any affect on overall coating stiffness and hardness. The multilayer coating in comparison with different configurations was also investigated. Result shows an increase in scratch adhesion of 18% and 27% for the optimal position and thickness of interlayers respectively. Qualitative comparison of in-plane residual stress shows higher stress in bi-layer and lower stress in multilayer with optimal thickness of interlayer. The approach in the study could be used to develop stress-optimized coatings for wear resistance applications. © 2015 Elsevier Ltd

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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
