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
Modelling prehistoric topography and vegetation in the lower Thames Valley, UK: Palaeoenvironmental context for wetland archaeology and evidence for Neolithic Landnám from north Woolwich
No full textMulti-proxy investigations at 2 Pier Road, North Woolwich, London, UK, have revealed deposits spanning the Middle-Late Holocene from the late Mesolithic (c. 4360 cal BC) onwards. Pollen data show an Elm Decline at c. 4210–3950 cal BC followed by landnám clearances at c. 4210–3910 cal BC and c. 3710–3030 cal BC and the first appearance of cereal at c. 3540–3030 cal BC. These events are potentially contemporary with the construction of nearby Neolithic trackways, providing indirect evidence for agriculture and settlement. REVEALS modelling shows the first significant reduction in woodland cover is coincident with the Neolithic Elm decline, but the main step-change to open conditions occurred in the Early Bronze Age, following a decline in lime at c. 2110–1630 cal BC. Palaeo-topographic modelling of the region shows that although the trend towards increasing openness coincides with gradual wetland expansion, the shift to open vegetation cover cannot be explained by this and is probably the result of human activity. This study highlights the value of combining deposit and vegetation cover modelling to contextualise wetland archaeology and shows that together these provide useful proxies for landscape-scale human activity that can identify ephemeral signals of prehistoric activity.</p
6918 Determining potential: onshore/offshore prehistory
No full textHistoric England commissioned a team from the University of Southampton to undertake project 6918, ‘Determining Potential: onshore/offshore prehistory’ between January 2014 and July 2015. The central focus of the research was on evaluating methods that might be used to help move from generic to more specific understandings of archaeological potential within such environs. A region of the Bristol Channel and Somerset Levels was chosen as the study area within which to carry out this work, due to its already noted high potential for contributing to our understanding of prehistory. Three overarching aims were given for the project: a. Assess the efficacy of predictive modelling for the determination of the potential for submerged prehistoric archaeology in English waters;b. Evaluate the range of methods open to archaeologists when assessing the potential for submerged prehistoric archaeology offshore, and how best to investigate/mitigate for it; andc. Extend our knowledge of key inter-tidal and offshore sequences in a region already known for its nationally significant inter-tidal and onshore prehistoric record.This monograph describes three different approaches to modelling potential: inductive, deductive and geoarchaeological. The conclusion is reached that inductive predictive modelling is currently an inappropriate method for improving our understanding of offshore potential (and in some instances deeply buried onshore locations) in England. This is due to low data density and high degrees of uncertainty with regard to prehistoric activity. Deductive and geoarchaeologically focused methods were found to hold much greater promise for determining potential. However, again the need for high quality input data was highlighted. All of the above approaches should be seen as iterative in nature, and require a commitment to improving data accessibility and joined up approaches to acquisition. It also requires a greater degree of communication with colleagues working in countries whose territorial waters directly abut England’s.The above recognition of the need to improve our baseline understanding of both palaeoenvironmental change and archaeological finds density is one of the most significant and challenging outcomes from this project. In carrying out the review to address point b above, and the fieldwork to address point c, it became clear that we need to sample larger volumes across a wider range of ecological niches. Put simply, without adopting methods that maximise the chance of recovering material culture offshore we will never be able to:1. Answer key research questions identified in regional and national research agendas that are pertinent to both the onshore and offshore archaeological record.2. Improve our ability to pinpoint areas likely to produce important finds.The lack of direct engagement offshore, the limited nature of inter-tidal investigations and the uneven distribution of commercial activity onshore has led to a record that is hard to interpret with regard to the specifics of potential, beyond discussion in the broadest terms. Rather than being a negative outcome this is seen to be a positive result. The act of creating a deductive model forced detailed analysis of the qualities of input data, and highlighted lacunae in our understanding. In ground-truthing the deductive model new information was generated that contributes to our growing appreciation of the complexities of environmental change across the study region, and areas in need of future research clearly identified. Finally, through accepting that we may not be able to answer questions we have already raised of the offshore record without a change in approach, this research establishes the urgent need for more detailed consideration of how we manage and carry out research into the submerged prehistoric record, as well as compiling and distributing these results
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
