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
Rheumatoid arthritis - patient perception of disease, care, quality of life, coping and well-being : a study from a Swedish health care district
No full textDuring the past decades, the focus of outcome studies in chronic diseases such as rheumatoid arthritis (RA) has changed from a technical and biological preoccupation towards a more patient-concemed psychosocial perspective. The changing paradigm of chronic disease impact has been conceptualised in a number of self-report health status and outcome measurements that have been called 11one of the primary achievements of rheumatology in the 1980s". The overall aim of the study was to make a broad elucidation of the perceived selfMreported impact of rheumatoid arthritis in a representative group of individuals from a health care district, with regard to treatment and care, quality oflife, coping and well-being.A total of 321 patients from a health care district in the northern part of Kalmar county, Sweden, with both early/mild and more severe disease were enrolled in the first part of the study, in which the medical records of these individuals were scrutinised for information about previous treatment and care. In the second part of the study, 222 of the initial 321 persons participated in an extensive postal survey exploring perceived impact of RA by self-report.The uncertain outcome of RA disease was emphasised by a high frequency of discontinuations of drug therapy due to lack of effect or side-effects. Underlining the lack of a medical cure for RA, more than 40% of the individuals had undergone some kind of surgical procedure due to the disease. The rehabilitation services to individuals with RA appear to be functioning fairly adequately since those still working were employed in administrative work rather than in production. The participants indicated a preference for a good reception by health care workers rather than technically correct care. Only a minority of the patients who had been treated as in-patients felt that they had been involved in the planning of the care. Also, the physicians seemed to underestimate the patients desire for information concerning both medical and social aspects of the disease.Quality of life scores exhibited a change for the worse with increasing self-reported functional disability. Physical, psychological and social life domains were fairly highly interrelated and all revealed lower levels with increasing self-reported functional disability. Also, lower levels of well-being were closely associated with a more severe RA disease, in particular loneliness, indolence, tension, security, future-orientation and endurance. Coping and wellMbeing were only weakly interrelated, but individuals who declared an active lifostyle exhibited a better well-being with a higher basic mood, greater fotureorientation and less indolence, loneliness and inferiority. Individuals accepting the RA disease displayed less guilt and tension, and greater endurance and basic mood.The study depicts how individuals with RA in a health care district are provided with both the basic treatment and more specialised care in a collaboration between medical and surgical specialists. In general, satisfaction with the care provided was more closely related with clinical signs rather than self-reported functional performance, although the latter might more adequately reflect the perceived need of the patients. Thus, the results support the application of self-reported functional disability assessment in routine clinical rheumatological practice. The study displays methods that measure and quantify the increasing negative psychosocial impact of RA with increasing functional disability. Some evidence was also found supporting the inclusion of coping enhancement elements in health care programmes targeting patients with RA. Consequently, the inclusion of counselling enhancing acceptance of the RA and encouraging decisions about new relevant goals might, at least theoretically, increase well-being in patients with RA.</p
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
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
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

Comparison of Systematic Versus Targeted Screening for Detection of Risky Drinking in Primary Care
No full textAim: To compare two identification methods for risky drinking in primary health care centres (PHCs). Methods: Sixteen PHCs from three Swedish counties were randomized into strands: consultation-based early identification (CEI) or systematic screening early identification (SS). Measurements took place at baseline and during two intervention periods. Patients filled in questionnaires including gender, age, if they had the issue of alcohol brought up during the consultation and the AUDIT-C (a three item screening tool). The intervention periods were preceded by training sessions for clinicians. The AUDIT-C was used for categorization of risky drinking with cut-offs for risky drinking set at andgt;= 5 for men and andgt;= 4 for women. In the SS strand, clinicians were supposed to give AUDIT-C to all patients for the identification of risky drinking. In the CEI strands, they were encouraged to use early clinical signs to identify risky drinking. Results: The proportions of patients having the issue of alcohol brought up are higher during the intervention periods than baseline. A higher proportion of all patients and of risk drinkers in SS, than in CEI, had the issue of alcohol brought up. A higher mean score of AUDIT-C was found among patients having the issue of alcohol brought up in CEI than in SS, and this was also true after adjusting for age and gender. Conclusions: More patients are asked about alcohol in the SS strand and thus have the possibility of receiving brief interventions. CEI identifies risk drinkers with higher AUDIT-C scores which might indicate more severe problems. No comparison of the effectiveness of a brief intervention following these alternative identification procedures is reported here.</p
