Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
The function of recycled lithic items at late Lower Paleolithic Qesem Cave, Israel. An overview of the use-wear data
No full textThe study of lithic recycling in Paleolithic cultures throughout the OldWorld is increasingly becoming a topic of interest for many scholars. Technological analyses, refitting, and spatial analyses are disclosing the “recycling behavior” of many contexts, especially those of Lower and Middle Paleolithic sites. Still lacking, however, is a functional approach to the subject, which would certainly add new pieces to this intriguing jigsaw puzzle. Use-wear analysis, one of the most powerful methods to reach functional interpretations in lithic finds, can greatly improve our understanding of Paleolithic recycling behavior. Even in those cases where post- depositional alterations affected lithic items, use-wear analyses may produce important data despite the decrease in detail or less than optimal conditions of preservation. At the late Lower Paleolithic site of Qesem Cave, the high degree of conservation and preservation of the lithic tools maximizes the inference potential of this method. In this article, functional data are summarized following a study of a large sample of Amudian parent flakes (flakes from which were produced cores on flakes, termed COF-FFs) as well as recycled products (blanks produced from COF-FFs). Confirming the inference potential of use-wear analyses, this data allows for the delineation of functional peculiarities of the studied items, which, despite first impression, are anything but expedient. Moreover, the current use-wear analysis expands the scenario outlined by the technological study of the lithic recycling phenomenon at QesemCave, confirming its own role in the complex techno-functional system practiced by the hominins of Qesem Cave
Variations on the Author
Full text link“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
Full text linkWe 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
Evidence for the repeated use of a central hearth at Middle Pleistocene (300 ky ago) Qesem Cave, Israel
No full textA major debate in prehistory revolves around the time and place of the earliest habitual use of fire and the hominin species responsible for it. Here we present a newly discovered hearth at Qesem Cave (Israel) that was repeatedly used and was the focus of hearth-centered human activities, as early as three-hundred-thousand years ago. The hearth, identified based on mineralogical and microscopic criteria, contains two superimposed use cycles, each composed of shorter - episodes possibly the earliest superimposed hearth securely identified to date. The hearth covers ca. 4 m(2) in area making it a uniquely large hearth in comparison to any contemporaneous hearth identified thus far, possibly indicating it has been used by a relatively large group of people. In addition, the hearth is located in the center of the cave and is associated with butchered animal remains and a dense flint assemblage. The flint assemblage indicates spatially differentiated meat cutting and hide working activity areas. The central location of the hearth within the cave and the activities associated with it may reflect an embedded perception of space organization of the Qesem Cave inhabitants. Since fire was habitually used throughout the 420-200 ky sequence of Qesem Cave, where preservation conditions are alike throughout, we suggest that this unique hearth may reflect a development in nature and most probably in the intensity of fire use in Qesem Cave, from ca. 300 ka ago onwards.
