Nápoles y Josep Sanchis Sivera: una evocación personal (1902)
No full textDurante la primavera de 1901, el historiador valenciano Josep Sanchis Sivera (1867-1937) realizó una interesantísima tournée que lo llevó a visitar diez ciudades italianas, entre las cuales Nápoles. Un viaje ciertamente emocionante y elocuente que, unos meses después, relató con todo tipo de detalles en el volumen titulado Dos meses en Italia (Impresiones y recuerdos) (1902). Así, en el transcurso de aquella narración, repleta de referencias artísticas e históricas aderezadas con anécdotas, destacan de una manera expresiva los capítulos dedicados a Nápoles, una metrópoli que el autor descubrió y evocó con erudición, emotividad y buen humor, con un evidente magnetismo. De este modo, el trabajo pretende analizar los lugares y las personas que Sanchis Sivera visitó y trató durante su estancia en la Campania

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
Previsional Acoustic Impact of the site work of the new metro line in Copenhagen
No full textThe City Circle Line (in Danish Cityringen) is a future expansion of the metro of Copenhagen that consists of two tunnels and 17 stations, all at 30 meters below ground level. The line, that should be operative in 2018, allows to connect some important areas of the cities of Copenhagen and Frederiksberg, replacing a part of the current bus services. The works needed for the construction of the Cityringen are quite noisy and the corresponding impact on the population is expected to be relevant.
In order to evaluate the acoustic impact of the site work, simulations have been carried out taking into account noise regulations and site specific conditions of the municipalities of Copenhagen and Frederiksberg. Particular attention was paid in the characterization of the noise power emission of the various machineries used in the different phases of the construction, as well as in the analysis of vibrations.
The goals of the paper are to describe the methodology used for the acoustical simulations and for the proposal of mitigation measures technically feasible
Use of the novel thrombopoietin receptor-agonist romiplostim, in combination with steroids and immunoglobulins for the increase of platelets prior to splenectomy, in refractory immune thrombocytopenia : a case report
No full textThis case report describes a patient with relapsed primary immune thrombocytopenic purpura (ITP), in which splenectomy was not possible due to the persistence of a low platelet count despite treatment with corticosteroids, intravenous immunoglobulins (IVIG) and platelet transfusion treatment. As an attempt to increase platelet count prior to performing splenectomy, the thrombopoietin receptor agonist, romiplostim, was administered in combination with steroids and IVIG. A single administration of romiplostim was found to be markedly effective, allowing a rapid and notable platelet increase, required for a well tolerated splenectomy. This case confirms the potent activity of romiplostim in ITP, and indicates that patients with recurrent primary ITP who are unresponsive to conventional immunosuppressive therapy may benefit from the addition of a short course of romiplosti
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
