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
Intravenous thiamine as a potential therapy for agitation and delirium in critically ill patients: a survey of clinicians perspectives
No full textIatrogenic Withdrawal Syndrome (IWS) in adult intensive care: a survey of UK healthcare professionals
No full textIntroduction: intravenous (IV) sedation and opioids are administered to intensive care unit (ICU) patients for anxiety, pain, and somnolence in mechanical ventilation. However, prolonged exposure to high medication doses places patients at significant risk of IWS upon abrupt cessation or rapid tapering of medications.1-3 IWS encompasses a combination of autonomic dysregulation, central nervous system arousal, and gastro-intestinal symptoms. It is associated with adverse clinical outcomes that include prolonged mechanical ventilation, psychological distress, longer hospital and ICU stay, higher morbidity, and elevated healthcare costs.4,5 There are increasing reports of IWS in ICU adults, but how it is recognised by healthcare professionals is less established.Objective: to determine ICU healthcare professionals’ perspective on incidence, detection and research in IWS in IV sedation and opioid use in adult ICU.Methods: The survey was registered as a service evaluation without the need for ethics. An online survey was piloted (Survey Monkey), revised and distributed via various professional societies of Irish and UK ICU community, addiction psychiatrists and social media. The survey was open for 16 weeks from 5 February 2023 with reminders sent for completion. Data was analysed using descriptive statistics.Results: 246 responses were received from ICU health care professionals including nurses 32% (79/246); pharmacists 30% (75/246); medical doctors (consultant-level) 27% (66/246); medical (other) 7% (17/246); allied health professionals 2% (5/246) and other 2% (4/246). Overall, 90% (221/246) indicated that IWS was a clinically important issue for adults in ICU and 80% (198/246) felt that a validated IWS screening tool would be useful for clinical practice. 24% (59/246) reported they were familiar with strategies for prevention and/or treatment of IWS and 13% (31/246) had IWS guidelines available in their ICU. 89% (218/246) stated that there is a need to improve clinical guidance for identification, prevention and treatment of IWS in dult ICUs. With 90% (220/246) reporting that more research is needed to understand the incidence and impact of IWS in adult ICUs.Conclusion: ICU professionals surveyed indicated that IWS was very common in their clinical practice and a majority reported the need for further guidance to identify and treat IWS. The absence of IWS screening tools, coupled with a lack of understanding regarding prevalence and treatment strategies, indicates a significant gap in clinical knowledge. Given the clinical importance; we strongly recommend further research and development to bridge these critical gaps and provide clinical guidelines.References:1.Cammarano WB, Pittet JF, Weitz S, et al.: Acute withdrawal syndrome related to the administration of analgesic and sedative medications in adult intensive care unit patients [Internet].

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
