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
The Effects of the COVID-19 pandemic in the UK- at a Local, National and International level perspective from the Emergency Department
Context: There is a significant burden on all emergency services in the management and prevention of the novel COVID-19 transmission. The effects are felt right across the World with certain geographical areas being most affected, it has affected all countries irrespective of their healthcare infrastructure. It has been suggested that certain parts of World that are prone to natural disasters are better prepared for pandemics. However, this is completely unfound as major economies are overwhelmed with the effects of the COVID-19 and it becomes completely irrelevant of any past experiences as these have been in never seen before scale. Evidence acquisition: The national fight against COVID-19 has been dubbed as the greatest fight for the National Health Service (NHS) with the entire United Kingdom under lockdown and the unfamiliar situation not seen before in peacetime. The general understanding of the disease process is that it has profound effects on the elderly and those with significant underlying health conditions such as cardiovascular, respiratory amongst others. However, it has surfaced from time to time that the very young are being affected and at times unfortunately been fatal. Results/Measures: The United Kingdom has been in a lockdown just like several nations across the globe in a desperate measure to limit the spread of the virus. There have been weeks of planning at every level for all possible eventualities with regards to the ongoing COVID-19 pandemic. All routine operations and procedures have been cancelled only procedures that emergency life and limb saving and cancer surgery continue to take place in hospitals all across the hospitals in the NHS. Widespread measures such as social distancing, calling a dedicated helpline for information and advice rather than attending the nearest Emergency Department have led to a significant number of presentations to the Emergency Department. Conclusions: The main concerns that remains for the NHS and other countries that have been affected is that once the lockdown restrictions are slowly eased will lead to a significant resurgence of cases that will overwhelm their respective healthcare infrastructures. From a clinician perspective, the main concern is the potential late presentations of the acutely unwell patients. This is the sentiment that is likely to be felt by many of my critical care colleagues working across NHS hospitals
The role of lactate to guide resuscitation: A clinician\u27s perspective
’Doctor, this patient’s lactate is raised at 4mmol/l, do you want to prescribe some fluid?’’. There have been many a time where we as clinicians have had similar encounters in our clinical journey. The reaction would be to prescribe intravenous crystalloids, however with time and recent emphasis on the importance of damage control/source control resuscitation this has been realised to be fraught with errors. The approach differs if the resuscitation is a medical or trauma based. The aim of this article is to explore some of the concerns that the emergency and critical care clinicians have from a raised lactate
An interesting case of an atraumatic painful swollen limb in a pregnant woman
Phlegmasia cerulea dolens is an uncommon complication of deep venous thrombosis. This is associated with high rates of morbidity if not treated effectively. We present a young lady 13 weeks pregnant with one-day history of left lower limb swelling with pain and discolouration. Bedside ultrasonography revealed thrombosis occluding the common femoral vein and collateral femoral vein. She had history of neonatal alloimmune thrombocytopaenia (NAIT), and had immunotherapy previously. The safest option was to give low molecular weight heparin (LMWH) on an inpatient basis. Anticoagulation with LMWH has been well established as thromboprophylaxis during pregnancy, however, the safety profile of systemic anticoagulation is matter of debate. As highlighted in this scenario the management needs to be tailored on an individual basis. The cause for the extensive deep vein thrombosis could be possibly due to the recent immunoglobulin therapy, undiagnosed prothrombotic state (outwith pregnancy) or the procoagulant state associated with pregnancy
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
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
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
