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
Clinical vs. Structured interview on anxiety and affective disorders by primary care physicians. Understanding diagnostic discordance
No full textSUMMARY. Aims – To assess in a national sample the ability of GPs to detect psychiatric disorders using a clinical vs. a standardized
interview and to characterize the patients that were falsely diagnosed with an anxiety or affective disorder. Methods –
This is a national, cross-sectional, epidemiological survey, carried out by GPs on a random sample of their patients. The GPs were
randomly divided into two groups. Apart from the routine clinical interview, the experimental group (group A) had to administer
the Mini-International Neuropsychiatric Interview (MINI). Results – Data was collected by 143 GPs. 17.2% of all patients had a
clinical diagnosis of an affective disorder, and 25.4% a clinical diagnosis of an anxiety disorder. In group A, the number of clinical
diagnoses was about twice that of MINI diagnoses for affective disorders and one and a half times that for anxiety disorders.
The majority of clinical diagnoses were represented by MINI subsyndromal cases (52.3%). Females showed a higher OR of being
over-detected by GPs with anxiety disorders or of not being diagnosed with an affective disorder. Being divorced/separated/widowed
increased the OR of over-detection of affective and anxiety disorders. The OR of over-detection of an affective or an anxiety
disorder was higher for individuals with a moderate to poor quality of life. Conclusions – In the primary care a gap exists
between clinical and standardized interviews in the detection of affective and anxiety disorders. Some experiential and social factors
can increase this tendency. The use of a psycho.

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
Association between medicine usage and respiratory disorders in Italian general population samples, according to coexisting nonrespiratory diseases
No full textAim: to assess drug use in subjects with respiratory symptoms/diseases (RD) or airflow obstruction (AO) according to non respiratory diseases (NRD). Methods: Through an interviewer-administered questionnaire, 4010 subjects (8-88 old, 48% males) from two Italian areas, provided information on: chronic use of any or specific (broncho-pulmonary/antiallergic/cardio-vascular/diuretic) drugs, diagnosis of asthma, diagnosis of chronic bronchitis/emphysema (COPD), COPD or chronic cough/phlegm (COPDsx), AO (FEV1/FVC < 70%), NRD. Results: Prevalences of asthma, COPD, COPDsx, and AO were 6.1, 4.7, 21.5, 12.9%, respectively. NRD (especially joint and cardio-vascular) was significantly more prevalent in subjects with RD or AO than in absence of these conditions (73 vs 62, 77 vs 60%, respectively). COPD subjects showed the largest use of drugs (59 for any and 38% for specific), followed by asthmatics (42 and 30%). After accounting for NRD, sex, age, residence, smoking habit, and education, all considered RD and AO resulted significantly related to medicines up-take. The strongest associations were for asthma (OR 1.96, 95%CI 1.40-2.54) and COPD (OR 1.96, 1.40-2.74), as concern any drug, and for asthma (OR 3.48, 2.35-5.16), as regards specific medicines. Except for asthma, the associations were considerably stronger when NRD was not included in analyses. Conclusion: Most people in the general population do not use drugs, in spite of reporting respiratory disorders. Coexistent non respiratory disorders have to be considered to better assess medicine consumption by subjects with respiratory disorders, especially with COPD or AO
