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
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

Strategie per implementare il monitoraggio della salute fisica in soggetti affetti da disturbi psichiatrici gravi: revisione della letteratura e presentazione dell’adattamento italiano del Positive Cardiometabolic Health Algorithm
No full textObjectives. To review the strategies implemented in clinical practice to increase monitoring and active interventions to reduce cardiovascular risk in individuals with severe mental illness and their possible implementation in first episode psychosis (FEP) care.
Methods. A PubMed literature search was performed using the following
key words: “metabolic syndrome”, “antipsychotic”, “schizophrenia”, “psychosis”, “severe mental illness”, “intervention”, “obesity”, “weight”, “physical health” and a combination of all above. Additional papers were identified through references and based on expert consultation as necessary.
Results. The review identified 14 studies in which a variety of different monitoring instruments were adopted in a range of clinical settings. Only three studies were carried out in subjects affected by FEP. The degree to which systematic monitoring was successfully utilised varied across studies and was mediated by a broad range of barriers. Nevertheless, some studies showed that the introduction of a systematic approach can improve the monitoring by up to 100%.
Conclusions. Despite heightened risk of developing cardiovascular and metabolic disorders, systematic monitoring of physical health is often suboptimal and haphazard. There is a paucity of specific protocols for people with FEP. Results seem more promising when the approach to physical health is multidisciplinary and integrated
with primary care. In this regard, a computerized version of the Australian Positive Cardiometabolic Health Algorithm, along
with a health check list completed by psychiatric nurses, seems
to be the basis to improve monitoring and effective interventions
aimed at preventing cardiovascular events in individuals suffering from FE
