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
Psychosocial Problems Secondary to Cancer: An Italian Multicenter Survey of Consultation-Liaison Psychiatry in Oncology
No full textData relative to consultation-liaison psychiatry (C-L) in oncology are lacking. In order to examine this area, a multicentre investigation was conducted in 17 general hospitals in Italy. All psychiatric consultation requests for cancer patients referred to C-L during a 1-year period were evaluated. Only 5% (n=217 referred patients: 114 men and 103 women) of all C-L activity were for cancer patients. Most were 'routine' consultations (72%) for current psychiatric symptoms (69%) or coping/compliance problems (12%). Previous psychological or psychiatric disorders were shown in 32% of cases. Approximately 40% of patients were not informed of their referral to C-L. The most frequent ICD-10 psychiatric diagnoses were adjustment disorders (27%) and major affective disorders (23%). Transfer to psychiatric units was low (1%). These findings indicate the need for improvement of referral criteria to C-L and closer attention to continuity of psychosocial care of cancer patients during hospitalisation and post-discharge
Perioperative management of patients with acute subarachnoid haemorrhage, do italians think differently?
No full textWith an incidence of 9 per 100.000 person-years, aneu rysmal subarachnoid haemorrhage (SAH) is an acute
cerebrovascular event, which can have devastating effects on
the central nervous system and a high mortality and morbid ity rate in ICU.1, 2 Despite many aspects of SAH therapy
still being controversial, prognosis could be improved by
therapeutic interventions and management procedure.1, 2
The Neuroanesthesia and Neurocritical Care Study Group
of Italian Society of Anaesthesia and Intensive Care Medi cine (SIAARTI) have participated with great interest into
the survey recently published by Valley et al. describing the
anesthetic management of SAH patients in Europe.3 The
main aim of this study was to highlight the great variabil ity in management of SAH patients. The Italian data are no

Purpose of review
Anesthesiologists and intensivists may be involved in the management of aneurysmal subarachnoid
hemorrhage (aSAH) patients at various stages of care. This article will review the recent advances
in the periprocedural management of aSAH patients.
Recent findings
New scoring systems to assess gravity and prognosis of aSAH patients have been evaluated and
proposed. Rebleeding still remains, with early aneurysmal treatment, a major challenge in the
first hours of aSAH management. In the last decades, the treatment of the aSAH has shifted from
clipping to coiling and more recently, the use of flow diversion technique has been introduced in
selected patients. Although these improvements allow treatment of more complex aneurysms, they
have implications for the anesthesiologist, including requiring the management of anticoagulation
with its inherent risks. Even though knowledge, monitoring, and management of postprocedural
phase of aSAH patients has improved, vasospasm and cerebral-delayed ischemia still remain the
major and devastating complications in the postoperative course of aSAH patients.
Summary
Despite recent progress in the scoring, diagnosis, and treatment of aSAH patients, the
periprocedural management of these patients is still a major challenge for anesthesiologists and
intensivists, who are involved from the first phase of the aneurysm rupture through the
postoperative phases and vasospasm period.

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
