Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Treatment and visual outcome in orbital and palpebral hemangiomas of infancy
Purpose
To study the relationship between the location of orbital and palpebral(eyelid)hemangiomas and ocular problems in children and the interventions needed to prevent or reduce the severity of visual impairment.
Methods
This study included 12 cases (10 female and 1 male;age range:1 day to 5 months old at first evaluation;mean age 2,5 months)of eyelid and/or orbit hemangiomas gathered over a 6 year period (2005-2011).Ultrasonography and magnetic resonance imaging(MRI)identified these lesions to be:palpebral in 2 cases, palpebral and orbital involvement in 9 cases.Pediatric and ophthalmological evaluation(orthoptic examination,visual acuity determination with Teller Acuity Cards,refractometry and fundus opthalmoscopy)were performed in all cases.
Results
The mean follow-up was 36 months (range 11-63 months)
Treatments for infants and children with hemangiomas obstructing the visual axis included oral steroid administration(9 cases);in 1 case a surgical treatment was associated.4 cases developed amblyopia and 1 case strabismus.Treatment of early amblyopia through selective patching part-time patch occlusion of the uninvolved eye and early prescription of astigmatism correction was performed.10 children achieved normal vision at last evaluation.
Conclusions
In our study 10 patients treated for visual impairment and available for long-term follow-up showed an excellent functional outcome with no residual amblyopia.In most cases,early intervention to address hemangioma-related visual disturbances can lead to a good functional outcome. Intervention typically involves medical debulking of the hemangioma(using oral steroids)combined with the treatment of early amblyopia through selective patching and/or optical correction with refractive lenses
LA SINDROME PSEUDO-APPENDICOLARE: RUOLO DELLA OSSERVAZIONE CLINICA E SUCCESSIVA EVOLUZIONE
Variations on the Author
“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
