No full textThe Sleep Knowledge of Pediatricians and Child Neuropsychiatrists.
No full textTo investigate the attitudes, practices and beliefs regarding children's sleep problems; their effect on the family; the actual treatment and beliefs of their efficacy; the basic knowledge of sleep and sleep disorders in children. A two-page questionnaire was sent to a representative sample of 8050 pediatricians (PED) and 1515 child neuropsychiatrists (ChNP). Questionnaire consisted of several questions on estimation of prevalence of sleep disordered patients, on beliefs about children's sleep difficulties, on the prescribed treatments, on reported effectiveness and on the overall effects of sleep problems on the family. A second questionnaire named Sleep Knowledge Questionnaire (SKQ) consisted of 30 true/false questions on sleep issues concerning 6 areas: developmental issues, sleep hygiene, parasomnias, sleep apnea, narcolepsy and miscellanea. A total of 751 questionnaires were returned: 627 from PED and 120 from ChNP. PED indicated that 18.60% of their patients experienced sleep problems, a lower percentage than that indicated by ChNP (21.81%). Pharmacological treatment was prescribed by 58.54% of PED and by 61.21% of ChNP Among non-pharmacological treatment, the majority of PED and ChNP recommended the establishment of a bedtime routine while a low percentage recommended Ferber's method. Both categories of physicians scored low in all areas of sleep knowledge investigated and particularly in questions about narcolepsy, sleep apnea and parasomnias. Results of the present study supported the need for more education in sleep and sleep disorders among Italian physicians and the necessity to change the physicians' approach to childhood sleep problems

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
