Routes of technology : pottery production and mobility during the Mesolithic-Neolithic transition in the Scheldt river valley (Belgium)
This research is focused on the transition from a hunter-gatherer way of life (‘Mesolithic’) to an agro-pastoral way of life (‘Neolithic’) in the Scheldt river valley in northern Belgium. Pottery is one of the Neolithic elements that was transferred to the Mesolithic groups in the study area, somewhere during the 5th millennium cal BC. By studying the pottery remains from six archaeological sites dating from this transitional period, we try to gain insight into (1) the presence of and contact with Neolithic groups in the study area and (2) when and how the knowledge of pottery production was transferred to the Mesolithic hunter-gatherer groups. The pottery-producing hunter-gatherers in the study area belong to the so-called “Swifterbant Culture”.
The Swifterbant Culture pottery from the Scheldt river valley was analysed by shape, decoration, and technology. For the latter, we tried to reconstruct the entire pottery production process: extraction of clays, preparation of clays, the way in which the vessels were built, shaped and finished. Next, this process was compared to the available information about the pottery technology from other Neolithic and hunter-gatherer groups of the adjacent areas.
The pottery technology of the Swifterbant Culture appeared to be very similar to that of a Neolithic culture of the loess soils in central Belgium and the Paris basin: the Blicquy/Villeneuve-Saint-Germain (BQY/VSG), dated to ca. 5000/4950 – 4750/4650 cal BC. The techniques used to make the vessel bases, to build the vessel bodies, and shape them afterwards, are identical. However, there are also obvious differences between these pottery traditions, for which an explanation must be found.
Another focus of this research is the direct dating of pottery. This was done in two ways: by dating food residue that is preserved on the vessel surfaces. And by dating plant (moss) remains that were once added to the pottery clay as temper. The food crust dates were systematically too old, as a result of the reservoir effect. When fish or other aquatic resources were prepared in the vessels, this has an ageing effect on the radiocarbon dates. Since fish is frequently prepared in the Swifterbant Culture vessels, the food crusts cannot be used for 14C dating. The moss temper dates, on the other hand, yielded good results. This is promising for future research
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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 start of pottery production by hunter-gatherers in the Low Countries (Swifterbant Culture, 5th millennium BC) : a critical assessment of the available radiocarbon dates
In this paper we critically review the earliest dates for pottery production by hunter-gatherers in the Low Countries (Swifterbant Culture). The start of pottery production in the Swifterbant Culture is traditionally set around 5000 cal BC. We argue that his date is largely based on pottery food crust dates, which have a probable reservoir effect due to the processing of freshwater fish in these vessels. If we focus only on the 14C dates of organic macro-remains, found within the same sediment layers as the pottery remains, then it is quite possible that the oldest Swifterbant Culture pottery actually dates between ca. 4800 and 4700/4600 cal BC
Variations on the Author
“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
We 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
