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
The tooth of time:Procedural sedation in nursing homes for frail, elderly patients
Full text linkThe group of frail elderly people with a major neurcognitive disorder is growing worldwide. Common problems associated with advanced stages of dementia include anxiety and the resulting inability to undergo medical or dental treatment. A possible solution to this problem is to offer anxiolysis or sedation. This should preferably take place in the patient's own, familiar environment. This dissertation contains studies into the possibility of helping elderly, vulnerable patients to undergo treatment in their own environment by providing safe, adequate procedural sedation
Intravenous drug dose optimization and drug effect monitoring in anaesthesia
Full text linkDit proefschrift onderstreept het belang van het optimaliseren van de dosering van anesthetica en geeft een beschrijving van de middelen die de anesthesiologen hebben om dit doel te bereiken. Twee belangrijke onderwerpen komen hierbij aan bod. Ten eerste hebben we onderzocht wat de invloed is van hersentumoren in de frontale hersenkwab op de pharmacokinetiek (de manier waarop het lichaam medicatie verwerkt) en pharmacodynamiek (de invloed van medicatie op het lichaam) van propofol bij patiënten die hieraan geopereerd werden. Op basis van ons onderzoek concluderen wij dat hersentumoren wel invloed hebben op de farmacokinetiek, maar niet op de farmacodynamiek van propofol. Ten tweede hebben we beoordeeld hoe effectief verschillende hypnose en analgesie monitors (BIS, CVI, CI, CS) zijn als hulpmiddel bij het optimaliseren van een anesthetische dosis in de algemene populatie. Uiteindelijk concluderen wij dat de huidige generatie hypnose en analgesie monitors anesthesiologen wel beter in staat stellen om de medicatie dosis te optimaliseren dan de huidige praktijk (standaard dosering schema’s en doseren op geleide van hemodynamische variabelen), maar dat ze nog steeds belangrijke tekortkomingen hebben
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
Pharmacological approaches for a novel GABAa receptor agonist:the long and winding road of drug development in anesthesia
Full text linkAlthough several intravenous anesthetic agents are used in daily clinical practice, the ideal anesthetic agent still does not exist (yet). In this PhD-thesis, various pharmacological approaches are used to investigate the novel anesthetic agent ABP-700 and to assess the extent to which it approaches the ideal anesthetic agent. In the first part of the thesis, its safety and clinical profile are assessed in a phase I clinical trial. ABP-700 seems to have various beneficial properties, as it provides hemodynamic and respiratory stability sometimes lacking in other anesthetic agents, and shows a fast on- and offset of clinical effect. However, one major side effect is the occurrence of involuntary muscle movements. The second part of the thesis zooms in on the origin of these muscle movements, which are seen in the use of other anesthetics as well. It could be concluded, that these movements are most likely not of an epileptic nature, but that they are more likely caused by a disequilibrium that occurs in the central nervous system during induction of anesthesia. This notion is supported by a pharmacokinetic-pharmacodynamic model that we developed, using the data that we gathered during the phase I trial. Also, it was observed that a certain intrinsic susceptibility for these muscle movements exists in certain subjects. In order to find out what this intrinsic susceptibility and the exact mechanism behind these movements are, further research is necessary
