Quod raro alias, praetorianus urbanusque miles in aciem deducti. Some considerations on the participation of the praetorian and urban cohorts in the civil wars of 69 A.D.: critical evaluation of the literary sources and the expedition against Narbonne Gaul (Part I)
No full textDuring the year of the four emperors the Praetorian Guard and the Urban cohorts played an important role in the military events of the civil wars. the paper examines some problems related to the involvement of these military corps in the military campaigns of AD 69. the literary sources often describe the Praetorians and the Urbaniniciani as passionate and violent, like the other milites of the Roman army, and moreover as second-rate and undisciplined soldiers; a careful analysis assesses if these descriptions are truthful or depend on the use of literary topoi and if the soldiers of urban troops were really inferior warriors to the legionaries serving on the frontier. Secondly, the paper examines accurately one of the conflicts in which the urban troops took part: the maritime expedition that Otho launched to attack Narbonense Gaul. the analysis of the literary and epigraphic documentation, thanks to new updated interpretations of the sources, fosters the acquisition of new and more precise historical information in order to reconstruct this military campaign
Quod raro alias, praetorianus urbanusque miles in aciem deducti. Unsolved problems and new interpretations on the movements and the composition of the urban troops during the civil wars of AD 69 (Part II)
No full textDuring the Year of the four emperors the Praetorian Guard and the Urban cohorts played an important role in the military events of the civil wars. The paper examines some problems related to the involvement of these military corps in the military campaigns of AD 69: the number of soldiers and cohorts participating in the different war scenarios, the movements and the fate of Otho’s Praetorians compared with Vitellius’ newly formed Praetorian cohorts. Moreover, in light to new interpretations of the sources, it analyzes the history and the composition of the four Urban cohorts created by Vitellius: in particular, I discuss the thesis according to which Vitellius mixed in legionaries formerly serving on the Rhine frontier and the old Otho’s urbaniciani within these new Urban cohorts
A priori estimates and large population limits for some nonsymmetric Nash systems with semimonotonicity
Full text linkWe address the problem of regularity of solutions (Formula presented.) to a family of semilinear parabolic systems of (Formula presented.) equations, which describe closed-loop equilibria of some (Formula presented.) -player differential games with Lagrangian having quadratic behaviour in the velocity variable, running costs (Formula presented.) and final costs (Formula presented.). By global (semi)monotonicity assumptions on the data (Formula presented.) and (Formula presented.), and assuming that derivatives of (Formula presented.) in directions (Formula presented.) are of order (Formula presented.) for (Formula presented.), we prove that derivatives of (Formula presented.) enjoy the same property. The estimates are uniform in the number of players (Formula presented.). Such a behaviour of the derivatives of (Formula presented.) arise in the theory of Mean Field Games, though here we do not make any symmetry assumption on the data. Then, by the estimates obtained we address the convergence problem (Formula presented.) in a ‘heterogeneous’ Mean Field framework, where players all observe the empirical measure of the whole population, but may react differently from one another. We also discuss some results on the joint (Formula presented.) and vanishing viscosity limit
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
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
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
