Palaeolithic reindeer hunting camps from Cosăuți (Middle Dniester, Moldova)
No full textSeveral Late Palaeolithic sites from the Middle Dniester area are characterized by specific artefact associations and archaeozoological assemblages that permit to include them in a particular category of reindeer hunting camps of the Palaeolithic communities. Among the Palaeolithic reindeer hunting camps, the multi-layered site of Cosăuți has a particular importance, since it includes more than two dozens of cultural layers dated from 20 to 14 thousand years BP. Nearly each of those strata exhibits an abundance of reindeer remains that represents up to 90% of the total archaeozoological material. The site of Cosăuți has yielded a variety of hunting weapons (spearheads, darts and spears, and a harpoon) that served for killing reindeer crossing the Dniester during the migration seasons. The geographical position of the site allows to control the part of the river valley where migrating reindeer herds crossed the Dniester and therefore the Cosăuți site had an advantageous strategical position. In many respects, the Palaeolithic site of Cosăuți resembles the location of the hunting camps of the ethnographically studied communities of caribou hunters in North America.Unele dintre siturile paleoliticului târziu din zona Nistrului mijlociu se caracterizează prin asocieri de piese și inventare arheologice specifice care permit atribuirea lor categoriei distincte a taberelor de vânătoare a renului specifice comunităților paleolitice. Între acestea, situl multi-stratificat de la Cosăuți are o importanța deosebită, având peste 20 de niveluri culturale datate în perioada 20 000– 14 000 BP. Aproape toate aceste straturi conțin numeroase resturi de ren, reprezentând cca. 90% din inventarul zoo-arheologic. Situl de la Cosăuți a produs o largă varietate de arme de vânătoare (diverse de tipuri de vârfuri și un harpon) utilizate în vânătoarea renilor care traversau Nistrul pe durata sezonului migrațiilor. Poziția geografică avantajoasă a sitului permitea controlul acestei părți a văii râului, acesta fiind locul pe unde turmele de reni traversau Nistrul. Din multe puncte de vedere, Cosăuți amintește de taberele de vânătoare documentate etnografic ale comunităților de vânători de caribu din America de Nord.Covalenco Serghei, Croitor Roman.

The Upper Valdarno Plio-Pleistocene vertebrate record: an historical overview, with notes on palaeobiology and stratigraphic significance of some important taxa
No full textThe Plio-Pleistocene fossiliferous mammal sites of the Upper Valdarno Basin (Tuscany, Italy) have been known since Renaissance times. Several mammal collections from there are housed at various Museums and Institutes. Various scientists or "fossil-hunters" collected all this material from Upper Valdarno over a long period of time up to the present days. We present here an overview of the history of these collections, as well as information on biochronology, taxonomy and palaeoecology on a selection of vertebrate taxa
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
Systematical position and paleoecology of the endemic deer Megaceroides algericus Lydekker, 1890 (Cervidae, Mammalia) from the late Pleistocene-early Holocene of North Africa
Get PDFInternational audienceThe unusual cranial morphology of the endemic extinct African deer Megaceroides algericus (Lydekker, 1890) is described. Some details of cranial and dental morphology suggest that M. algericus is closely related to the Eurasian giant deer Megaloceros giganteus (Blumenbach, 1799). The paper presents also a discussion on paleoecology and functional morphology of M. algericus, as well as its origin, phylogenetic and taxonomic position. Megaloceros mugarensis (Di Stefano, 1996) from the middle Pleistocene of Levant is regarded as a probable forerunner of M. algericus
