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
Searching for factors associated with the “Revolving Door phenomenon” in the psychiatric inpatient unit: A 5-year retrospective cohort study
No full textThe revolving door (RD) phenomenon refers to subjects who undergo frequent rehospitalizations in psychiatric units. The main aim of this study was to analyze clinical factors associated with RD in acute inpatient psychiatric ward. In a 5-year cohort study, subjects hospitalized three or more times in 12 months (revolving door subjects-RDS) were identified. A total of 1,324 subjects were hospitalized. RDS represented 6.3% (n = 84) of the entire sample with a total of 337 RD hospitalizations (revolving door hospitalizations-RDH) (16.7% of all admissions). RDS were younger, unmarried, with comorbid substance related disorders, with mood or psychotic disorders and affected by comorbid medical conditions. After controlling for age, sex and marital status, the most strongly associated variable with RDH was the comorbidity between mood and substance use disorders. Other associated factors were the presence of a comorbid medical condition and a longer length of stay. The commitment to community residential facilities and the treatment with a first generation long-acting antipsychotic were also associated with RDH. On the contrary, admissions to the psychiatric unit for manic/hypomanic episode or for self-directed harmful behavior were inversely associated with RDH. Attention should be given to these clinical variables in order to reduce RD
Oral versus long-acting injectable antipsychotics: Hospitalisation rate of psychotic patients discharged from an Italian Psychiatric Unit
No full textObjective: The primary aim is to verify the efficacy of long-acting injectable (LAI) and oral antipsychotics (AP) in terms of rehospitalisation rate of patients with psychotic disorders. The second aim is to evaluate socio-demographic and clinical differences in patients that were re-hospitalised after the index discharge compared to patients that were not re-hospitalised. Finally, socio-demographic and clinical differences of re-hospitalised patients that were prescribed at discharge with oral or LAI AP were analysed. Methods: A retrospective observational study including all patients discharged with diagnosis of psychotic disorders from July 2011 to July 2013 was conducted. Patients discharged with LAI or with oral AP were included. Re-hospitalisations occurred during a followup period of 24 months after the index discharge were considered. Chi-square test or Student's t-test were used for comparisons. Odds ratios (OR) and 95% confidence intervals (CI) for the incidence of re-hospitalisation for LAI or oral AP were provided. Results: No significant differences between LAI and oral AP in terms of re-hospitalisation rate in a 24-month period were found. Clinical and socio-demographic characteristics did not significantly differ between the groups. Conclusions: LAI seemed to be similar to oral AP in terms of prevention of re-hospitalisation in psychotic patients
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
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
