    La paternità e le sue trasformazioni sono oggi tematiche di grande interesse per le scienze sociali e umane. Il presente volume intende offrire un inedito contributo in tale direzione riflettendo, nello specifico, sulle radici del percorso di costruzione sociale del ruolo paterno. Come, oggi, l'esperienza concreta del concepimento, la gravidanza e la nascita influiscono sull'identità maschile e paterna? I capitoli che compongono il testo - curato da una sociologa, da uno psicologo e da una geografa - rispondono a tale domanda toccando alcune dimensioni chiave per la comprensione del delicato processo di transizione verso la paternità: la riorganizzazione identitaria maschile conseguente all'annuncio della gravidanza; la costruzione narrativa del ruolo paterno; il ruolo giocato dalle nuove tecnologie e dai corsi pre-parto nella preparazione alla paternità; il fenomeno della depressione post-partum "al maschile"

    Multiple firing of motoneurones is produced by cortical stimulation but not by direct activation of descending motor tracts.

    In the present report we have tested whether stimulation of the motor descending tracts at the brain-stem level could set up repetitive motor unit discharges in a similar manner to that described for motor cortical stimulation. We have seen that a large descending motor volley, evoked by brain-stem stimulation, cannot produce repetitive firing of motor units. Repetitive motoneurone firing is therefore produced by multiple excitatory volleys set up by single cortical shocks

    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
