Céréales, mauvaises herbes et faucilles : à la recherche des premiers agriculteurs au nord des Alpes
No full textThe study of data collected in the pile-dwellings from the region between the southwest of Germany and the Jura Lakes offers an achieved picture of the development of early agricultural practices between the 5th and the 4th millennium BC. Cultivated plants – mainly cereals – as well as ruderals and harvest tools trace the arrival of different currents of neolithisation. Information on the location and the length of life of the villages, deforestation and development of crop fields describe progressive anthropisation of the landscape.L’étude des données recueillies dans les palafittes de la zone comprise entre le sud-ouest de l’Allemagne et les lacs du pied du Jura donne une image achevée du développement des premières pratiques agricoles entre le Ve et le IVe millénaire avant notre ère. L’apparition de plantes cultivées, principalement des céréales, des mauvaises herbes et des outils de moisson permettent de tracer l’arrivée de différents courants de néolithisation. La localisation et la durée des villages, les indications relatives à la déforestation et à la préparation des champs destinés aux cultures décrivent l’anthropisation progressive du paysage.Maier Ursula, Schlichtherle Helmut, Borrello Maria Angelica.

The prehistoric lake-shore dwellings around the Alps between the 5th and the 3rd Millennium BC.
No full textConnus sous le nom populaire de palafittes, les habitats préhistoriques construits sur les rives des lacs subalpins du Néolithique à l’aube de l’âge du Fer (entre 5300 et 700 av. J.-C.) offrent des informations exceptionnelles sur l’évolution culturelle d’une importante région européenne, grâce à la préservation remarquable des matériaux organiques, en particulier du bois. À partir de la deuxième moitié du XXe siècle, le perfectionnement des techniques de fouille subaquatiques et de la dendrochronologie permettront la construction d’un schéma chronologique précis pour l’Europe nord-alpine. Les recherches contribueront à des observations d’ordre écologique à l’échelle locale et régionale et à l’identification des rythmes de développement des villages. Sous l’égide de l'UNESCO, les années 2010 verront la constitution d’un inventaire vaste et uniforme des sites préhistoriques des lacs circumalpins, classés Patrimoine culturel mondial en juin 2011.The prehistoric lakeshore dwellings of the Alps were built between the Neolithic and the dawn of the Iron Age (from 5300 to 700 BC). They offer exceptional information about the cultural evolution of a large European region due to the remarkable preservation of organic materials, in particular wood. From the second half of the 20th century, the advancement in excavation techniques and the development of dendrochronology will allow the construction of a chronological framework for central Europe, as well as local and regional ecological observations and the identification of the rhythms of villages' development. Under the auspices of UNESCO, the 2010s see the establishment of a broad and harmonized inventory of prehistoric lake-shore settlements of the alpine and listed as World cultural heritage in June 2011
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
