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
Pharmacists’ role in the management of patients receiving dual or triple antithrombotic therapy
Get PDFPurpose: Patients on dual and triple antithrombotic therapy present the therapeutic dilemma of mitigating bleed risk while sustaining antithrombotic efficacy. Lack of literature and variability in existing published guidance potentiates inconsistent management of these patients. Furthermore, suboptimal dosing of direct oral anticoagulants is relatively common. One study reported as high as 43% of patients receive higher and 13% receive lower than clinically indicated doses. These findings were associated with a significantly increased risk of major bleeding and incidence of stroke, thus highlighting the importance of selecting an ideal regimen. The purpose of this project is to highlight pharmacists’ role in the optimization of antithrombotic therapy in patients with concurrent indications for antiplatelet and anticoagulant agents.
Methods: This was a single center, quality improvement project including adult patients concomitantly receiving at least one antiplatelet agent and a therapeutic-dose anticoagulant between January and March 2021 at Baptist Hospital. Eligible patients were assessed and evaluated on a daily basis. Data collection included indications for prescribed antithrombotic agents and rationale for clinical recommendations. Potential therapeutic de-escalations and/or dose adjustments were communicated with the provider as necessary. The primary outcome of this study was appropriateness of anticoagulant and antiplatelet therapy based on their specific indications. Secondary outcomes included the types of pharmacy interventions made and accepted.
Results: A total of 239 patients receiving dual or triple antithrombotic therapy were prospectively reviewed over the 10-week study period. The average age was 74 years, and 56% of patients were male. The majority of regimens reviewed (95.4%) were dual antithrombotic therapy. Overall, 82% of all reviewed regimens were considered appropriate at time of pharmacist review (85% of dual therapy regimens and 27% of triple therapy regimens were appropriate). After pharmacist intervention, regimen appropriateness increased to 97% overall, with dual therapy regimens adjusted to 96.5% appropriate (78% acceptance rate) and triple therapy regimens adjusted to 100% appropriate (100% acceptance rate). The most common intervention was antiplatelet discontinuation (46%), however the most clinically significant intervention was discontinuation of oral anticoagulation (7.8%).
Conclusion: Pharmacist intervention resulted in optimization of dual and triple antithrombotic therapies by 15% with an intervention acceptance rate of 83%. Triple antithrombotic regimens had the greatest room for optimization, as was demonstrated by a 73% increase in regimen appropriateness as a result of pharmacist review and intervention
