    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Soon after the introduction of second-generation antipsychotics, antipsychotic off-label use (OLU) progressively became a common prescribing practice. This evolving practice should be regularly monitored considering the growing number of persons exposed to the adverse effects of antipsychotics. The aim of the present review was to synthesise the literature published over the last 15 years on antipsychotic OLU for mental health symptoms. Observational studies confirm the persisting high rate of antipsychotic OLU prescription in two out of three youths and 30-60% of adults using antipsychotics. Increasing rates of low-dose quetiapine prescriptions for anxiety or sleep symptoms are paradigmatic of the current public health concern regarding antipsychotic OLU. Such prescriptions receive impetus from industry-funded marketing strategies and prescribers' feeling of innocuousness, with a resulting underestimation of the risk of adverse drug reactions (ADR). However, antipsychotic OLU should be neither trivialised nor demonised since it may be the only therapeutic option in persons with resistant psychiatric disorders or serious ADR with labelled drugs. To reduce the populational impact of antipsychotic OLU, it is necessary to better control the influence of the pharmaceutical industry regarding newly marketed drugs and to better inform prescribers and users about the risks associated with OLU prescribing

    Variations on the Author

    “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 link
    We 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 link
    We 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

    We 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

    Clozapine monitoring: Have the times come for changing the rules?

    Full text link
    International audienceBackground A significant proportion of people with resistant schizophrenia do not receive treatment with clozapine, despite its clearly established efficacy in this indication. The constraints associated with haematological monitoring are a major obstacle to clozapine use, resulting in a real loss of opportunity for the people concerned. Objective The aim of this opinion article is to question the relevance of maintaining the existing haematological monitoring rules for clozapine treatment. Discussion Recent studies on the temporal evolution of agranulocytosis risk attributable to clozapine confirm that this risk becomes negligible after one to two years of treatment. Stringent haematological monitoring leads to unjustified discontinuation of clozapine, as transient neutropenic episodes, which may be linked to other causes are common in the general population. Haematological monitoring requires nursing time and sometimes complex organisational adaptations in outpatient facilities to ensure continuity of care, particularly at a time when medical and paramedical staffing levels are low. Haematological monitoring has already been reduced or suspended in several countries after the period of risk of agranulocytosis. Conclusion The benefit/risk ratio of maintaining strict haematological monitoring rules for clozapine appears unfavourable, suggesting that the time may have come to reduce the risk of agranulocytosis.Contexte Une proportion importante de personnes avec une schizophrénie résistante ne bénéficient pas d’un traitement par clozapine malgré son efficacité clairement démontrée dans cette indication. Les contraintes liées à la surveillance hématologique constituent un frein notoire à l’usage de clozapine, entraînant une vraie perte de chance pour les personnes concernées. Objectif Cet article d’opinion a pour objectif de questionner la pertinence du maintien des règles de surveillance hématologique actuellement en vigueur. Discussion Les études récentes sur l’évolution temporelle du risque d’agranulocytose imputable à la clozapine confirment que celui-ci devient négligeable au bout d’un un à deux ans de traitement. La surveillance hématologique entraîne des arrêts non justifiés de clozapine, car des épisodes neutropéniques transitoires pouvant être liés à d’autres causes sont fréquents en population générale. La surveillance hématologique mobilise du temps soignant et nécessite des adaptations organisationnelles parfois complexes dans les structures ambulatoires pour garantir la continuité des soins, notamment en cette période de sous-effectif médical et paramédical. La surveillance hématologique a déjà été allégée ou suspendue dans plusieurs pays après la période à risque d’agranulocytose. Conclusion Le rapport bénéfice/risque du maintien de règles strictes de surveillance hématologiques de la clozapine paraît défavorable, suggérant que les temps pourraient donc être venus d’assouplir ces règles
