    Traditional fusion methods for treating symptomatic segmental disc disease, which include discectomies (decompression) and arthrodesis (with or without decompression), are considered the standard of care in many instances. However, there are numerous problems and disadvantages coming out of these procedures: the loss of spinal mobility and flexibility, a permanent change of motion characteristics and biomechanics, and grafting collapse that determines suboptimal sagittal balance. In addition, one of the most prevalent concerns following fusion at one or more levels is the transfer of stress to adjacent levels, which often requires new surgeries, complications, and more pain. The new motion preserving technologies offer significant advantages, including maintenance of motion range as well as the mechanical characteristics, the restoration of the natural disc height and the spinal alignment, significant pain reduction, and preservation from adjacent segment degeneration. Is it true? Our experience about. Copyright © 2008 by new Magazine edizioni s.r.l

    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

    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
