Alfred Maugard et la vie théâtrale à Québec en 1871
No full textOn a peu réfléchi à la place qu’occupe le théâtre dans la ville de Québec dans la deuxième moitié du xixe siècle. Le présent article revient sur cette période, pour saisir le rôle qu’a pu y jouer le comédien français Alfred Maugard, qui arrive en 1871 avec la Compagnie française des Antilles. Celui-ci a fait toute sa carrière dans les provinces françaises de France, de Suisse et de Belgique et au cours de nombreuses tournées dans les colonies du Pacifique. Arrivant à Québec, il trouve une ville qui n’a pas de théâtre permanent et il y établit la première troupe professionnelle francophone de son histoire. Pendant une décennie, il assure une activité théâtrale avec l’aide des amateurs locaux et malgré l’opposition réitérée des ultramontains et du clergé.Little thought has been given to the place of theatre in Québec City in the second half of the 19th century. This article looks back at this period, to understand the role played by the French actor Alfred Maugard, who arrived in 1871 with the Compagnie française des Antilles. He spent his entire career in the French provinces of France, Switzerland and Belgium and toured extensively in the Pacific colonies. Arriving in Québec City, he found a city that did not have a permanent theatre, and there he established the first professional troupe in its history. For a decade, he provided theatre in French with the help of local amateurs and despite repeated opposition from the ultramontanes and the clergy
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
Variations on the Author
No full text“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
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
Biotransformation of halogenated compounds by lyophilized cells of Rhodococcus erythropolis in a continuous solid-gas biofilter
No full textThe irreversible hydrolysis of 1-chlorobutane to 1-butanol and HCl by lyophilized cells of Rhodococcus erythropolis NCIMB 13064, using a solid–gas biofilter, is described as a model reaction. 1-Chlorobutane is hydrolyzed by the haloalkane dehalogenase from R. erythropolis. A critical water thermodynamic activity (aw ) of 0.4 is necessary for the enzyme to become active and optimal dehalogenase activity for the lyophilized cells is obtained for a aw of 0.9. A temperature of reaction of 40 ◦ C represents the best compromise between stability and activity. The activation energy of the reaction was determined and found equal to 59.5 kJ/mol. The absence of internal diffusional limitation of substrates in the biofilter was observed. The apparent Michaelis–Menten constants Km and Vmax for the lyophilized cells of R. erythropolis were 0.011 (1-chlorobutane thermodynamic activity, aClBut ) and 3.22 µmoles/min g of cell, respectively. The activity and stability of lyophilized cells were dependent on the quantity of HCl produced. Since possible modifications of local pH by the HCl product, pH control by the addition of volatile Lewis base (triethylamine) in the gaseous phase was employed. Triethylamine plays the role of a volatile buffer that controls local pH and the ionization state of the dehalogenase and prevents inhibition by Cl− . Finally, cells broken by the action of the lysozyme, were more stable than intact cells and more active. An initial reaction rate equal to 4.5 µmoles/min g of cell was observed
Nonconventional hydrolytic dehalogenation of 1-chlorobutane by dehydrated bacteria in a continuous solid-gas biofilter
No full textRhodococcus erythropolis NCIMB 13064 and Xanthobacter autotrophicus GJ10 are able to catalyze the conversion of halogenated hydrocarbons to their corresponding alcohols. These strains are attractive biocatalysts for gas phase remediation of polluted gaseous effluents because of their complementary specificity for short or medium and for mono-, di-, or trisubstituted halogenated hydrocarbons (C2-C8 for Rhodococcus erythropolis and C1-C4 for Xanthobacter autotrophicus). After dehydration, these bacteria can catalyze the hydrolytic dehalogenation of 1-chlorobutane in a nonconventional gas phase system under a controlled water thermodynamic activity (aw). This process makes it possible to avoid the problems of solubility and bacterial development due to the presence of water in the traditional biofilters. In the aqueous phase, the dehalogenase activity of Rhodococcus erythropolis is less sensitive to thermal denaturation and the apparent Michaelis-Menten constants at 30°C were 0.4 mM and 2.40 μmol min−1 g−1 for Km and Vmax, respectively. For Xanthobacter autotrophicus they were 2.8 mM and 0.35 μmol min−1 g−1. In the gas phase, the behavior of dehydrated Xanthobacter autotrophicus cells is different from that observed with Rhododcoccus erythropolis cells. The stability of the dehalogenase activity is markedly lower. It is shown that the HCl produced during the reaction is responsible for this low stability. Contrary to Rhodococcus erythropolis cells, disruption of cell walls does not increase the stability of the dehalogenase activity. The activity and stability of lyophilized Xanthobacter autotrophicus GJ10 cells are dependant on various parameters. Optimal dehalogenase activity was determined for water thermodynamic activity (aw) of 0.85. A temperature of 30°C offers the best compromise between activity and stability. The pH control before dehydration plays a role in the ionization state of the dehalogenase in the cells. The apparent Michaelis-Menten constants Km and Vmax for the dehydrated Xanthobacter autotrophicus cells were 0.07 (1-chlorobutane thermodynamic activity) and 0.08 μmol min−1 g−1 of cells, respectively. A maximal transformation capacity of 1.4 g of 1-chlorobutane per day was finally obtained using 1g of lyophilized Xanthobacter autotrophicus GJ10 cell
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
