La Triste Sologne. L’utilisation du sol dans une région française à l’abandon au début du XIXe siècle
No full textAfter having defined the limits of the Sologne, which lies to the south of the bend the Loire makes at Orléans, and having recalled the general features of the region's physical geography and its dismal situation at the end of the 18th century, the author next presents the first ideas and attempts to improve the «sad Sologne».
Working from documents included in an old survey, giving precise statistics concerning land-use, he then draws up, by means of a series of maps, a picture of the economic situation in the Sologne at the beginning of the 19th century.
He examines successively the most common sorts of land utilisation in the Sologne : arable land, woods and forests, moors, ponds, vineyards. Using ordnance maps prepared in 1822-40, the author then provides other interesting information concerning land-use and the state of communications, still very unsure, at the beginning of the 19 th century. In conclusion, the overall picture of the Sologne between 1830 and 1840 was still that of a region with a backward and underdeveloped agriculture.Après avoir délimité la Sologne qui s'étend au Sud du coude que la Loire fait à Orléans, et rappelé les caractères généraux de la géographie physique de celte région et la situation misérable dans laquelle elle se trouvait à la fin du XVIIIe siècle, l'auteur fait connaître tout d'abord les premières idées et tentatives d'amélioration de «la triste Sologne».
— Se basant sur les documents incorporés à l'ancien cadastre, donnant des statistiques précises sur l'utilisation du sol, il fait ensuite, au moyen d'une série de caries, un tableau de la situation économique de la Sologne au début du XIXe siècle.
— Successivement, il examine les types de sols les plus répandus de la Sologne, les terres arables, les bois et forêts, les landes, les étangs, les vignobles.
— Utilisant les relevés de la Reconnaissance militaire effectués entre 1822 et 1840, l'auteur donne enfin d'autres renseignements intéressants sur l'utilisation du sol et l'état encore très précaire des communications au début du XIXe siècle.
— En conclusion, le tableau d'ensemble de la Sologne, entre 1830 et 1840, était encore celui d'une région à l'agriculture arriérée et sous-développée.Sutton Keith, Lenfant M. La Triste Sologne.

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
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
