Evidence of the palaeolithic: a digital reconstruction, prior to the landfill, of Rookery Farm, Lower Kingswood, UK
Full text linkThe use of digital geospatial methods to reconstruct lost and/or buried landscaped has become an essential tool of archaeological exploration. Inherently, the level of success depends on the availability of information and the construction of comprehensive datasets. Discussed in this research report, are the various techniques and procedures undertaken by the PADMAC Unit over several years, to establish the location of a ‘lost’ Palaeolithic knapping-site which was originally revealed during the construction of a landfill site in a small dry valley at Rookery Farm, Lower Kingswood, Surrey during 1959. The knapping-site was described by L.W. Carpenter to have been situated on the deposits mapped as Clay-with-flints at the edge of the high plateau, overlooking the valley. Subsequent infilling of this valley destroyed and buried the site (the area has now been returned to agricultural use). The report of this specific discovery and the fact that throughout the 1950s and 1960s Carpenter had also found many Palaeolithic artefacts as surface-finds in this area inspired others to search for further evidence of the Palaeolithic. Surveys of Rookery Farm and the immediate area, were undertaken, trenches dug by F.F. Pemberton and artefacts found, but the question of the exact location of the ‘lost’ knapping-site remained, as did the concerns regarding the location of the Pemberton trenches and the effects of the construction of the landfill site on the integrity of the more recent Palaeolithic finds in the area. To better understand site formation in the archaeological area of Rookery Farm, the PADMAC Unit embarked on a long-term plan of geophysical investigations; soil/sediment analyses; geospatial 3D modelling, spatial analyses and Palaeolithic artefact technological analysis in an attempt to both model the location of the ‘knapping site’ and the Pemberton trenches and to resolve questions regarding the integrity of the Palaeolithic surface-scatters/sites on the deposits mapped as Clay-with-flints. Comprehensive datasets were constructed from the results of the Rookery Farm, borehole and trial pit investigations commissioned by Surrey County Council and Reigate & Banstead Borough Council. Additional material in the form of annotated maps, letters regarding the infilling (rubbish tipping) at Rookery Farm and ecological assessments, were also made available to the PADMAC Unit. To determine the potential of the Rookery Farm assemblages to yield a source information on the behaviour of Palaeolithic people, a technological analysis of the artefacts was made, and the results compared and contrasted with data the PADMAC Unit had obtained from the geoarchaeological investigation of other high-level Palaeolithic sites on deposits mapped as Clay-with-flints in the UK. Also, the raised-beach Palaeolithic site at Boxgrove, Sussex
Dolores Scott Jackson, Oral History
No full textThis is a video recording of an oral history interview with Dolores Scott Jackson. It was conducted January 22, 2019. The interviewer is Gwendolyn Savage. The videographer is Jeremy Glossup.
This interview focuses on Dolores Jackson\u27s memories of growing up in Delta County, Texas.
Dolores Jackson was born in 1939 and raised in Charleston, Texas. Her parents were Jack and Glenna Oats Scott. She has fond memories of growing up in Charleston, the family dairy, and school. Following graduation Jackson attended East Texas State College, now Texas A&M University-Commerce. She graduated in 1960 and married Roy Lee Jackson. The couple moved to Grand Saline, Texas, where Jackson worked as a teacher and her husband worked for Morton Salt. Five years later they moved back to Charleston.
Jackson saw many changes in her community over the years, remembering the poor roads and the development of electricity and water supplies. Jackson worked as an educator and is proud of her students\u27 accomplishments. Following her retirement from teaching, Jackson continued to be involved with the community through volunteering.https://lair.etamu.edu/scua-oral-history-all/1012/thumbnail.jp
Evidence of the Palaeolithic: a digital reconstruction, prior to the landfill, of Rookery Farm, Lower Kingswood, UK
Full text linkIn all good detective stories there are several facets to the plot. Identifying the facts that matter and those which are no more than a distraction, is vital to solving the mystery.
A classic example of an abstruse situation and the approach taken to determine both the location of a previously reported Palaeolithic knapping-site (now seemingly destroyed and buried beneath rubbish in a landfill site) along with the integrity of the recently identified Palaeolithic surface-scatters/sites on the high-level plateau at Rookery Farm, Lower Kingswood, Surrey, are addressed in this geoarchaeological research report. Surface-scatter/site investigations are generally considered ‘difficult’ in the sense of understanding site-formation and ascertaining archaeological integrity. As surface-scatters (particularly those on high-level plateaus and hilltops) may be the only evidence of a Palaeolithic presence in a region/country and could be indicative of embedded (i.e. in situ) site/s at that specific locale. This is an important challenge to be addressed.
In 1999, the PADMAC Unit was set up (at the University of Oxford) with the first guide to investigating and excavating high-level Palaeolithic surface-scatters/sites published in 2000 (Scott-Jackson, 2000). The prescribed techniques use methods and concepts of the earth sciences that have, by definition, been extended to the study and interpretation of sediments and landscapes. The Unit continues to develop the modelling framework which includes geophysical techniques, geospatial 3D modelling, spatial analysis, soil/sediment analysis and artefact techno-typological analysis and to expand the range of techniques and methodologies for the investigation and excavation of Palaeolithic surface-scatters/sites in various environments (Scott-Jackson, 2011).
This range of techniques and methodologies have now been widely deployed both in the UK and the Middle East (see http://users.ox.ac.uk/~padmac) in areas of Palaeolithic research as diverse as: resolving competing ‘Out of Africa’ models; early hominin use of the landscape; landscape exploitation; migration patterns and population change; lithic procurement; stone-tool manufacture (techno-typological analysis); usage of stone-tools and inter-regional (and arguably inter-species) comparative analysis of these various factors. It is anticipated therefore, that this research report will serve as a useful addition to the Palaeolithic archaeological record of Rookery Farm, Lower Kingswood

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
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
