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
Non-invasive ventilation outsie of the intensive care unit: an Italian survey
No full textBACKGROUND: Non-invasive ventilation (NIV) is increasingly utilized for patients with acute respiratory failure (ARF). The shortage of Intensive Care Unit (ICU) beds, a growing confidence with the technique, and the opportunity to treat ARF in a more responsive phase lead to the application of NIV outside of the ICU. The Study Group on Emergency of the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI) promoted a national survey to collect data on NIV use outside of the ICU.
METHODS: An anonymous questionnaire was developed, focusing on the location and modalities of NIV treatments, organizational and technical aspects, monitoring, estimated outcomes, the presence of protocols, and complications. The questionnaire was mailed to all members of the Scientific Society.
RESULTS: Forty-six respondents were from 46 hospitals. Thirty-seven (80%) respondents applied NIV in the Emergency Department and/or General Wards. In the majority of hospitals (72%), training preceded NIV introduction. NIV could be applied in all ordinary wards in 28% of the hospitals. Patients remained in their ward in 89% of the hospitals, and a protocol was present in 70% of the hospitals. Monitoring was usually limited to continuous pulse-oxymetry and EKG; 18% of respondents did not have a monitoring standard. Reported complications and practical problems were potentially severe. Few hospitals (15%) collected data on NIV treatments. The efficacy of NIV was perceived as low, as 73% of respondents estimated that NIV avoided tracheal intubation in less than half of the treated patients.
CONCLUSION: In Italy, NIV is extensively applied in non-intensive wards, and its use is not free from criticalities and contradictions. Further prospective studies and possibly guidelines are needed
