Human exposure, analysis and reinforcement of evacuation capabilities against tsunami in Padang (Indonesia)
No full textCette thèse résume une démarche intégrée visant à évaluer l’exposition humaine et ses variations spatio-temporelles en cas de tsunami dans une zone urbaine littorale en Indonésie, ainsi que la capacité d’évacuation vers des refuges. Ce travail de recherche systématise des méthodes permettant d’estimer la quantité de population présente heure par heure durant n’importe quel jour de la semaine et de l’année, à une échelle très fine, dans une zone urbaine. Il se fonde pour cela sur une hypothèse de rythme de vie contrôlant les activités et donc la distribution de la population. L’heure d’arrivée d’un tsunami étant imprévisible, ces informations sont très importantes pour améliorer les programmes de réduction du risque. Cette démarche permet ainsi de dégager des scénarios types de distribution de la population, utilisés pour ensuite évaluer la capacité d’évacuation de ces populations. Le modèle de simulation dynamique issu de cette recherche permet de mesurer l’accessibilité des zones selon certains scénarios, et de proposer des améliorations pour une meilleure préparation de la protection des civils.This dissertation summarizes an integrated approach whose aim is to assess the human exposure and its spatial and temporal variations in the event of a tsunami in a costal urban zone of Indonesia, as well as the capacity to join evacuation shelters for populations under threat. This research systematizes methods to estimate the amount of people present hour by hour during any day of the week and the year, at a very fine scale, in an urban area. It uses a hypothesis about a common rhythm of life which controls the activities and therefore the distribution of the Padang inhabitants. Considering that time of a tsunami occurrence is impossible to estimate, this information is very important to improve risk reduction programs. This approach allows in particular identifying various types of scenarios for the distribution of the population that can then be used to evaluate the evacuation capacity of these populations. A dynamic simulation model resulting from this research allows for the measurement of the accessibility of shelters following these scenarios. The analysis of the results suggests improvements for a better preparation on the part of authorities to protect civilians

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
