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
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
Un colpo al cerchio ed un colpo alla botte: il ruolo del flumazenil nelle disintossicazioni miste alcol-benzodiazepine.
No full textBenzodiazepine (BZD) are the therapeutic tool of choice in the treatment of alcohol and Gamma Hydroxybutyrate (GHB) dependence even if BZD can cause tolerance and drug dependence themselves . The BZD, alcohol and GHB withdrawal symptoms have many traits in common and they can be both severe1. Occasionally, chronic use of BZD can reach the size of a real abuse2,3; this situation, when in comorbidity with a severe alcohol or GHB dependence, poses some problems in the clinical management of detoxification for the cross-tolerance phenomenon. This can entails a longer hospitalization and increased costs. It is little known and even less applied the technique of BZD detoxification by using the flumazenil slow infusion (FLU-SI), although the first clinical trial dates back to 20 years ago4. Flumazenil allows rapid detoxification because, when infused slowly, it acts as a partial agonist and it quickly normalizes the uncoupling of GABA-A receptors caused by BZD abuse 4-6. We present 2 case reports: a fast detoxification from a combined abuse of alcohol and very high-dose of BZD, and a fast detoxification from a combined abuse of GHB and BZD dependence by using FLU-SI
Figli di un dio minore: il trattamento del tabagismo nei pazienti con malattie mentali
No full textTobacco addiction, a major world-wide health problem, is widely recognized as a chronic, relapsing mental disorder, disproportionaltely affecting people with psychiatric comorbidity that smoke and develop smoke-related diseases more than smokers without mental illness. Paradoxically, these patients receive fewer invitations to stop and less support in the process of smoking cessation.
The treatment of smoking addiction may give good results in these patients if properly performed. First-line drugs proved to be effective also for these patients.
Aim of this review is to present scientific data in the literature in order to make a breach in the wall of neglect that too often surrounds people nicotine dependent with mental illness and to give an opportunity to these patients, generally suffering of severe smoking dependence.
Even more hoped would be that the local mental health services to take charge of this serious problem by providing pharmacological treatment and behavioral support to their own patients
