Why we need a national strategy for liver disease
No full textFor the last 10 years the British Association for the Study of the Liver and the British Society of Gastroenterology Liver Section have been campaigning for greater recognition of liver disease as an important priority for the NHS. Deaths from liver disease are escalating at a frightening rate (Figure 1) (British Association for the Study of the Liver, 2009). Based on current trends, the death rate from liver disease will exceed cardiac deaths by 2030. This needs to be reversed before we get to this ridiculous scenario - over 95% of all liver diseases are entirely preventable or treatable, and deaths from liver disease occur at an average age of 55 years rather than ~82 years for cardiac disease or stroke. To stop this we need to reduce the rising tide of alcoholic liver disease and fatty liver disease, and actively treat the increasing number of patients with chronic hepatitis B and
The research interface between biosecurity and tourist behaviour
No full textThere is growing acknowledgement of the links between the behaviour of tourists and concerns arising from a range of issues that fall under the rubric of 'biosecurity'. Despite recessions, volatile oil prices and terrorist incidents and threats, global tourist movements continue a long-term trend of steady increase. At the same time, the interpenetration of national economies has resulted in increased biosecurity strains of both economic and ecological significance. This paper develops an overview and framework that makes explicit the conceptual terrain created by the overlap, or potential overlap, of research on these two highly significant global phenomena. We highlight the various scales, dimensions and aspects of this interface and argue that there is considerable urgency over the need to develop and pursue a coherent research agenda in this area. Suggestions are made regarding initial possibilities for advancing such a research agenda
Sport in Museums
No full textThis book explores, in breadth and depth, the role of sport in museums.
It surveys the history of sport in museums, including the growth in sport museums and halls of fame driven by major sports teams and sport organisations. The book considers the humanistic benefits of the promotion of sporting heritage within museums, and presents cases, museums stories and best practice from around the world.
Sport in Museums is essential reading for all students, researchers, curators, and historians with an interest in sport. It is also a useful resource for researchers and advanced students working in museum studies, heritage studies or cultural histor
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
A chemiluminescense-based assay for S-nitrosoalbumin and other plasma S-nitrosothiols
No full textThe lack of a simple assay for the quantification of S-nitrosothiols in complex biological matrices has hampered our understanding of their contribution to normal physiology and pathophysiological states. In this paper we describe an assay based upon the release of nitric oxide by reaction with a mixture consisting of Cu(I), iodine and iodide with subsequent quantification by chemiluminescense. With this method we can detect levels of S-nitrosothiols down to 5 nM in plasma. Following alkylation of free thiols with N-ethylmaleimide, and removal of nitrite with acidified sulfanilamide, we were able to measure known amounts of S-nitrosoalbumin added to plasma or whole blood, with an inter-assay variation for plasma S-nitrosothiols of approximately 4%. Further studies showed that the mean concentration of circulating S-nitrosothiols in venous plasma of healthy human volunteers was 28+/-7 nM
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
