Die neolithischen Ufersiedlungen von Twann. Band 12: Die Überreste der Dörfer von Cortaillod. Stand der Forschung 1980 (Sedimentologie, Strukturen und Chronologie)
Get PDFDie durch die Projektierung der Nationalstrasse N5 ausgelöste Grossgrabung der jungsteinzeitlichen Siedlung von Twann fand zwischen 1974 und 1976 statt. Der vorliegende Band 12 der 20-teiligen Reihe befasst sich in einem ersten Teil mit den verschiedenen Besiedlungsphasen der Cortaillod-Zeit, die sich in den Abschnitten 6–12 über die Stratigrafien erschliessen liessen. Im zweiten Teil der Publikation werden die Ergebnisse der dendrochronologischen Untersuchungen vorgelegt
Die neolithischen Ufersiedlungen von Twann. Band 4: Archäologische Analyse der Sedimente. Großflächige Anwendung der Methode und Ergebnisse (Caissons 6 und 7: Cortaillod-Zivilisation).
Get PDFDie durch die Projektierung der Nationalstrasse N5 ausgelöste Grossgrabung der jungsteinzeitlichen Siedlung von Twann fand zwischen 1974 und 1976 statt. Der vorliegende Band 4 der 20-teiligen Reihe setzt sich mit der Analyse der Sedimente der Cortaillod-Schichten auseinander. Anhand von Beschreibungen und Profil(-Fotos) wurden sie nach Farben, Zusammensetzungen, Ausdehnungen sowie im Hinblick auf Veränderungen in der Fläche und ihrer stratigrafischen Lage mit dem Ziel untersucht, Siedlungsphasen anhand der Differenzierung von gleichzeitig abgelagerten Sedimenten zu fassen
Les crises catastrophiques du glissement des Parchets (Préalpes vaudoises, Suisse) : indices d'une augmentation des précipitations extrêmes entre 2000 et 1500 14C B [ Catastrophic events on the Parchets landslide (Western Swiss Prealps) : indicators of an increase of extreme precipitations between 2000 and 1500 14C BP.P]
No full textThe Les Parchets landslide is formed of flysch and argilaceous schists and was built up by successive mudflows. Dendrochronological analysis of 37 trunks, which have been extracted in excavations, allowed us:
- to demonstrate the catastrophic nature of the movements;
- to identify three successive events;
- to date the first event from the year 97;
- to date the following events between the years 300 and 450 and between 400 and 540 respectively.
Datings obtained one kilometer from this site in fluvial terraces, indicate a dramatic increase of torrentiality in the main river, progradation of a debris cone and progression of a deep landslide since ca 2000 14C BP. All these results indicate a strong increase of extreme precipitations during roman times.Le glissement des Parchets affecte des flysch et des schistes argileux de l'Ultrahelvétique, et s'est mis en place par coulées boueuses successives. L'analyse dendrochronologique de 37 troncs d'arbres mis au jour lors de chantiers de construction de chalets a permis:
- de démontrer la nature catastrophique des mouvements;
- d'identifier et de délimiter trois événements successifs;
- de dater le premier événement de l'an 97 après J.C.;
- de dater les deux événements suivants respectivement entre l'an 300 et 450 et entre l'an 400 et 540 après J.C..
Des datations obtenues à un kilomètre de là dans des terrasses fluviatiles indiquent une augmentation brutale de la torrentialhé dans la rivière principale, une forte progradation d'un cône torrentiel latéral et une progression d'un grand glissement de terrain profond à partir de 2000 14C BP environ. Tous ces résultats concordent et indiqueraient une forte augmentation des précipitations extrêmes à l'époque romaine.Schoeneich Philippe, Tercier Jean, Hurni Jean Pierre, Orcel Christian, Orcel Alain.

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
