THE ROLE OF BIOMECHANICS IN PERSONAL INJURY COMPENSATION: FIRST RESEARCH OUTCOMES FROM AREYOUFINE? INTRODUCTION
No full textSelf-Inserted Needles in the Heart
No full textCardiac injuries due to penetration by sharp foreign bodies usually have a clear clinical presentation. A case of a 38-year-old man with self-inserted cardiac lesions and a misleading presentation is reported. The patient was admitted to the emergency room because of chest pain, with increase in biomarkers of myocardial necrosis, and electrocardiographic and echocardiographic abnormalities inducing initial diagnostic and therapeutic workup of acute coronary syndrome. Once clinical destabilization followed by death had occurred, the suspicion of an alternative diagnosis came from delayed chest radiography, confirmed by autopsy, revealing the presence of multiple metallic objects within the thora

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
Regulating pediatric off-label uses of medicines in the EU and USA:challenges and potential solutions: Comparative regulation framework of off label prescriptions in pediatrics: a review
Full text linkBackground Off-label uses of medicines are common in pediatrics. The literature reports that at least one-third of children in hospital and up to 90% of newborns in neonatal intensive care units receive off-label prescriptions. Moreover, the lack of data on safety and efficacy in the pediatric population may sometimes increase the risk of adverse drug reactions. Objective This paper aims to (a) map the main gaps in the existing EU and US regulatory frameworks for pediatric drug development and off-label use and (b) propose potential solutions for further discussion. Conclusion The selected jurisdictions aim to limit off-label prescribing, but implementation levels generally seem low, including in pediatric settings. Subject to further research, we propose potential concerted actions and initiatives of international cooperation to fill this gap. In particular, regulators and pediatric societies could strengthen manufacturers' incentives to develop pediatric medicines, pediatricians' information about off-label uses, and patients' and parents' awareness
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
