Paleoecology of the foraminifer Acruliammina longa (Tappan, 1940) from the upper Hauterivian of the Neuquén Basin (northern Patagonia, Argentina)
No full textHerein the epibiont agglutinated placopsilinid foraminifer Acruliammina longa from the upper Hauterivian of the Neuquén Basin is discussed. This is the first record from South America of A. longa, already known from the upper Valanginian to lower Turonian? of North America and Europe. The studied material consists of foraminiferal tests forming macroids and encrusting the valves of Ptychomya koeneni, coming from poorly lithified claystones/siltstones to marlstones forming high frequency (6th-order) depositional sequences within the upper Hauterivian Agua de la Mula Member of the Agrio Formation. This new record extends the paleobiogeographic distribution of A. longa, and allows us to investigate the paleoenvironmental and paleoecological significance of this species in a mixed carbonate and siliciclastic ramp. Energy dispersive spectroscopy and X-ray computed microtomography were used to evaluate taphonomic features of foraminiferal tests, highlighting differences between tests that encrust bivalves and those forming macroids, which also differ in their position within the 3rd-order sedimentary sequences. A. longa tests encrusting bivalves are less damaged, show coarser grain size, and occur throughout the 3rd-order regressive systems tracts, whereas tests forming macroids show higher breakage and finer grain size, occurring throughout the 3rd-order transgressive systems tracts. This distribution allows us to interpret changes in rates of terrigenous input at the time of encrustation, and also in energy conditions, highlighting the opportunistic behavior of A. longa. Low sedimentation rates represent the main paleoenvironmental condition that favored foraminiferal propagule settlement and the growth of A. longa, both on bivalve fragments exposed on the seafloor in the case of macroids, and on living Ptychomya koeneni shells.Fil: Caratelli, Martina.

La terza gamba del tavolo umano. Una riflessione su mito e sinistra a partire da Mitocrazia di Yves Citton = The third leg of the human table. A reflection about myth and the Left starting from Mitocrazia by Yves Citton
No full textThe third leg of the human table. A reflection about myth and the Left starting from Mitocrazia by Yves Citton. Starting from the recent book Mythocratie, written by Yves Citton, the essay tries to comprehend the relationship between myth (and generally the narrative dimension of human rationality) and politics, deconstructing the common idea about sort of a necessary connection between mythology and right wing. Moving through the philosophical categories of different thinkers, the reflection goes from the anthropological dimension of our narrative cognitive structures through the construction of mythological political horizons to the unavoidable duty of thinking a left-wing way of using myth without losing a critical and enlightened tensio

The paleontological collection of Egidio Feruglio at MUST
No full textMany fossil specimens whose collection is attributable to Egidio Feruglio were found in the repositories of the Paleontology Museum in the Department of Earth Sciences of ‘Sapienza’ University of Rome, soon became MUST. The material can be traced back to the activity which Feruglio did in Argentina during his two stays between the twenties and forties of the twentieth century. Different available information about this material mainly deriving from tags, label and hand written notes combined with specimens, were organized and are here provided as subsidiary to future museum’s activities
Variations on the Author
No full text“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

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
