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
Sulla sostituibilità ospedale-territorio
No full textNel lavoro si cerca di individuare se la relazione tra spese sanitarie effettuate sul territorio sia legata alla spesa ospedaliera da una relazione di complementarietà o di sostituibilità, argomentando che la prima sembra prevalere, cosicché il corrente trasferimento di risorse verso l'assistenza territoriale stessa potrà apportare solo ridotti vantaggi per la spesa sanitaria pubblica totale
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
Are Bruxellois and Walloons more optimistic about their health?
No full textUsing the data collected for the year 2004 in the Belgian Health Survey, we aim to show that, controlling for all the determinants of self-reported health state, there is a residual effect of geographic location on the self-assessed health, namely a more favourable scoring for individuals that are resident both in the region of Brussels and in the region of Walloonia, with respect to individuals that are resident in the Flanders. Regional effects do not change either if we take account of supply of health services or if we control for their utilization. Moreover the effect of past level of health is encompassed to test for habituation, and the results still hold. The above findings can be used both to construct “equivalent expected QALY’s or EEQ” ,i.e. the average quality adjusted life years that a newborn, taking account of the different average level of health at the regional level, can expect to experience in the different geographical areas of Belgium (the three regions have approximately the same EEQ), and to predict a “need factor” to be used either for equity analysis or to ascertain its evolution in time.Self-assessed health; Quality of life; QALY’s; Regions of Belgium; Health Survey; Ordered Probit.
Are people from Brussels and walloons more optimistic about their health?
No full textUsing the data collected for 2004 in the Belgian Health Survey, we aim to show that, after examining all the elements used in determining a self-reported state of health, geographic location bears considerably on the results of self-assessed health, namely a more favourable scoring was registered for individuals that are resident both in the region of Brussels and in the region of Wallonia, with respect to a more negative outlook for individuals that are resident in Flanders. Regional effects do not change, however, even when taking into account the supplying of health services or when controlling their utilization. Moreover, the estimate also considered the adaptation behaviour, represented by health transition and these results still hold true. The above findings can be used both to construct “equivalent expected QALY’s or EEQ”, i.e. the average quality adjusted life years that a newborn, taking account of the different average level of health at the regional level, can expect to live in the different geographical areas of Belgium (the three regions have approximately the same EEQ), and to predict a “need factor” to be used either for equity analysis or to ascertain its development in time.Self-assessed health; Quality of life; QALY's; Regions of Belgium; Health Survey; Ordered Probit
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
