Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Secretin-enhanced MRCP: How and Why-AJR expert panel narrative review
No full textSecretin-enhanced MRCP (S-MRCP) has advantages over standard MRCP for imaging of the pancreaticobiliary tree. Through the use of secretin to induce fluid production from the pancreas and leveraging of fluid-sensitive MRCP sequences, S-MRCP facilitates visualization of ductal anatomy, and the findings provide insight into pancreatic function, allowing radiologists to provide additional insight into a range of pancreatic conditions. This narrative review provides detailed information on the practical implementation of S-MRCP, including patient preparation, logistics of secretin administration, and dynamic secretin-enhanced MRCP acquisition. Also discussed are radiologists' interpretation and reporting of S-MRCP examinations, including assessments of dynamic compliance of the main pancreatic duct and of duodenal fluid volume. Established indications for S-MRCP include pancreas divisum, anomalous pancreaticobiliary junction, Santorinicele, Wirsungocele, chronic pancreatitis, main pancreatic duct stenosis, and assessment of complex postoperative anatomy. Equivocal or controversial indications are also described along with an approach to such indications. These indications include acute and recurrent acute pancreatitis, pancreatic exocrine function, sphincter of Oddi dysfunction, and pancreatic neoplasms
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
The destiny of italian prisoners in austro-hungarian pow camps during the first world war: Remembering the defeat of caporetto 100 years on
Full text linkThe living conditions of Italian prisoners during the First World War were extremely difficult. At the end of the conflict, the treatment of Italian soldiers in Austro-Hungarian POW camps and in those of the German territories was recognized as particularly harsh in comparison with that of other prisoners. The reasons may be ascribed to three main factors. The Italian prisoners paid the price of being considered traitors, since Italy was allied with the Austro-Hungarian Empire and with Germany until 1914, subsequently switching to the side of France, the United Kingdom and Russia. The Italian government and the Italian High Command considered their soldiers poorly inclined to engage in a war which became over time increasingly costly in terms of human sacrifice. The strategy pursued by the General-in-Chief Luigi Cadorna was very aggressive and showed little care for the life conditions of his troops, who were frequently thrown into the fray and exposed to potential slaughter. Due to this negative judgement on their troops’ willingness to fight, the government did not help, and even hindered, the despatch of packages of food and clothes to prisoners in the Austro-Hungarian and German camps via the Red Cross. The idea of a better life in the trenches compared with that expected in the camps as prisoners was widespread. Thirdly, the maritime blockade of the Adriatic Sea over time reduced to starvation the populations of Austria, Hungary and Germany, which obviously had grave repercussions on prisoners. It was estimated that around 100,000 Italians lost their lives in POW camps; after the defeat at Caporetto, when over 250,000 prisoners were captured, the number of deaths rose. The main causes of death were: tuberculosis, pneumonia, malnutrition and typhoid fever. At the end of the war, when coming back to Italy, former POWs were interned for months in camps (located predominantly in the Emilia region) and had to face interrogation and trials to demonstrate they were not deserters and were free to go back home. In the meantime, many lost their lives due to “Spanish” flu, pneumonia and other infectious diseases. Only the mobilization both of families and public opinion forced the Italian government to close the camps at the end of the year 1919
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
