Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Early sex and its behavioral consequences in New Zealand
No full textA steady trend towards earlier sexual intercourse is now well documented. However; the relationship of this development to trends in other early sexual formative experiences has not been explored, nor has there been an analysis of the longer-term behavioral consequences. The data examined in this paper were drawn from a two-stage national survey of sexual lifestyles on a sample of 2,361 adult New Zealanders in the age range 18-54. Techniques of survival analysis and multiple logistic regression were used Over time there was a consistent decline and diminishing gap in age of onset for first experience, first intercourse, and first regular partnership. Multivariate analysis confirms that males, the young, the less educated ethnic minorities, and respondents professing no religious affiliation were all more likely to report earlier onset of sexual experiences. However; while all three socio-sexual events showed the same trend pre-intercourse experiences exerted the strongest influence on subsequent sexual practices and outcomes. This has implications for preventive strategies.Am - Accepted Manuscrip
Patterns of care and professional decision making in a New Zealand general practice sample
No full textIt is hypothesised that professional and organisational factors will significantly influence the pattern of care in general practice. This hypothesis is assessed for four key activities: laboratory test orders, prescriptions, referrals, and request for follow up. The data are drawn from a 1% sample of all weekday general practice office encounters in the Hamilton health district recorded over a twelve-month period from February 1979. Overall, 16% of patients receive a laboratory test, under two-thirds a prescription, 8% are referred, and under half receive a specific request for follow up. Interpractitioner variation in activity is substantial for each service: orders for laboratory tests vary between 1% and nearly half of all patients seen, the upper limit of activity for both prescribing and follow up is four patients in five, while rates of referral vary between 0 and 20%. Professional and organisational attributes exert a limited influence on this variation in service activity. Nevertheless, older practitioners, those trained outside New Zealand or without postgraduate qualifications, solo practitioners and practices with high volumes, with low fees and located outside Hamilton, have slightly lower rates of laboratory test orders and slightly higher rates of prescribing. These effects persist after controlling for diagnosis. In a multivariate analysis, diagnostic criteria are seen to be of overwhelming importance in the determination of activity levels. The identity of the practitioner is also a significant influence. Overall, the model accounts for only a fifth of the variation in activity level.VoR - Version of Recor
