When the waters recede: The economic impact of tsunamis in the Graeco-Roman world
No full textThis article investigates the impact of ancient tsunamis on the ancient World. Nowadays, the effects of such events on contemporary economic is easy to assess and investigate, thanks to the amount of information available. More complicated is the picture for pre-modem societies. The aim of this paper is precisely to focus on the economic consequences, if any, of tidal waves on certain regions and periods of the classical world. As a matter of fact, the study of natural disasters has been a popular topic for modem scholarship of the Antiquity. Along the Mediterranean basin, ancient tsunamis usually devastated regions with high levels of seismic activity, such as the Balkans, the South-East, the Levant or the central and eastern islands. Most of the archaeological evidence from tsunamis and earthquakes, however, has been mixed up by a combination of geological and human activity, making it difficult to single out which is which. Tsunamis were less frequent than earthquakes but their impact on human communities and their available natural resources could have been more catastrophic, at least in the short-term. The unexpected nature of such tidal waves surely produced considerable unrest within the affected population, who might have been familiar with the devastating effects of earthquakes but most probably were unaware of such a rare natural phenomenon. Our main goal, however, is to ascertain the economic impact of ancient tsunamis on the 'longue-durée'. The article is composed of two main parts. In the first one, we examine the evidence for tsunamis occurred in the Mediterranean basins from fifth century BC till the fourth AD, before the great tsunami of AD 365. It is possible to recognize how the Graeco-Roman literature describes, in some cases with remarkable accuracy, the basic functioning of what geologists know as tsunamis, but generally fails to provide any information on the economic impact of them on the ancient societies. In the second part, we focus on the tsunami of AD 365, for which we have more information, provided by both literary and documentary evidence, allowing us to use it as an interesting case study with a particular relevance in the ancient history. The final conclusion is that tsunamis in antiquity, as far as it is possible to infer from the status of our sources, despite having probably a huge damaging effect on the economy on the short term, usually did not affect it on the 'longue-durée', given, most likely, to efficient policies devised by ancient civilizations, to cope with such events

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
