No full textObjective: The aim of the study was to compare the results obtained through two different TEOAE devices applying the same screening procedure.
Materials and methods: From 2004 to 2006, a first group of 1439 newborns (group A) was evaluated with TEOAE Eclipse device and a second group of 778 newborns (group B) from 2007 to 2008 was evaluated with TEOAE AccuScreen device. For the hearing screening we applied two different three-phases protocols, one for well-babies and one for babies with audiological risk.
Results: In the first phase of our protocol we obtained 9% FAIL in the group A and 4% FAIL in the group B. In the second phase were referred 15% of the group A and 2% of the group B. The ABR testing revealed one severe bilateral hearing loss and one monolateral hearing loss in the group A and one monolateral hearing loss in the group B. All three hearing impairments occurred in well-babies.
Conclusion: Both the devices lead to an early detection of hearing loss in newborns and can be used for the screening procedure. In the group B we obtained fewer false positives and the number of infants lost during follow-up was smaller. The test with the AccuScreen was faster with a reduced number of FAIL responses because the effectiveness of the test was less influenced by ambient noise contamination. We strongly recommend a universal hearing screening and an effective follow-up in order to early detect a progressive or late-onset hearing impairment
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
