Grattanuvole. Un secolo di grattacieli a Milano
No full textAlla luce delle grandi trasformazioni in atto nella città di Milano - che coinvolgono, in particolare, la zona Garibaldi-Repubblica e l’area dell’ex Fiera Campionaria - la mostra intende ripercorrere la storia dei grattacieli milanesi e le alterne fortune che questa tipologia architettonica ha incontrato nella nostra città. Una storia lunga un secolo, che prende avvio con la prima proposta di “grattanuvole” presentata nel 1910 dall’ingegnere Achille Manfredini (un edificio di oltre 50 metri che avrebbe dovuto sorgere in corrispondenza dell’attuale piazza Missori) e che si conclude - ma solo provvisoriamente - con i progetti di Porta Nuova. Una storia che attraversa tutta la vicenda dell’architettura moderna a Milano e che si nutre dell’immaginario che questa ha saputo suscitare: dalle mitografie futuriste di Antonio Sant’Elia (ricordiamo che quest’anno ricorre il centenario del Manifesto dell’Architettura Futurista a cui la mostra farà omaggio) fino ai virtuosismi tecnologici di Daniel Libeskind e di Zaha Hadid. Una storia che coinvolge circa 80 grattacieli e torri e che viene raccontata con l’ausilio degli strumenti canonici del progetto (piante, prospetti, sezioni, viste prospettiche e foto d’epoca estratti dai fondi documentari dell’Archivio Storico Civico del Comune di Milano e di vari fondazioni private), ma anche cogliendo l’impatto del grattacielo sul vissuto della città, attraverso una nuova campagna fotografica, videointerviste, un video con i grattacieli milanesi in 3D, un itinerario guidato in città, conferenze e seminari.
Il fulcro dell’esposizione è il nuovo skyline di Milano con al centro il progetto e i nuovi grattacieli di Porta Nuova che rappresentano l’estensione del progetto urbanistico del Centro Direzionale,
inclusi i grattacieli di piazza della Repubblica, il Pirelli, il Galfa e la nuova sede della Regione Lombardia. Le altre sezioni della mostra riguardano sia i grattacieli “storici” (dal 1910 al 1990), sia i più recenti (dal 1990 ad oggi), riletti attraverso considerazioni critiche e focus sugli edifici più significativi.
Mostra promossa dal Politecnico di Milano - Scuola di Architettura e Società e Dipartimento di Architettura e Studi Urbani (DAStU), svolta dal 6 Novembre al 6 dicembre 2014 presso la Fondazione Riccardo Catella di Milano
Cross-sectional geometry of a warlike Samnite sample from the Alfedena necropolis (Iron Age, Italy)
No full textProblems of an aquatic diet in trace element analysis: The coastal site of Qurum RH5 (Sultanate of Oman, 3.700-3.200 b.C.)
No full textTrace elements analysis, as an indicator of ancient diets, has been carried out to the human skeletal remains from the necropolis of RH5 and RH10 of Qurum (Sultanate of Oman, 3700-3200 B.C.). Soil samples from the inner part of the burials, shells, fish, turtles and herbivorous remains have been analyzed. Regarding the human bones, a first set (ribs) was related to 26 females and 41 males while a second set (femurs) was related to 22 females and 34 males. Four trace elements, among the most common indicators of diet, have been taken into consideration (barium, strontium, zinc and copper) for their stability to diagenetic effects. Manganese has been analyzed to determine the incidence of diagenesis. Data from the two sets of human bones show a narrower range of values for the femurs than for the the ribs, in agreement with a lower incidence of diagenesis in compact bones. A wider range of values from the animal samples show a higher incidence of diagenetic effects in these remains. Low levels of variability can be stressed for the soil samples. Post-mortem exchange could have more likely occurred in the outer parts of spongy bones, as manganese seems to show. The wide range of values from the ribs and, on the contrary, the narrow range from the femur indicate that an accurate choice of sample can reduce the effects of diagenesis. Regarding the alimentary habits of the groups from Qurum, the human samples (both males and females) show high rates of strontium, similar to the herbivorous. This could be associated to an aquatic diet. It is unlikely that the high levels of strontium could be linked to a high incidence of vegetables in the diet. Also archeological data seem to stress a prevalence of aquatic food in the diet. Not always do statistical analyses applied to groups with different anthropological or chronological characteristics give clear answers to the identification of ranges of values, but they have always been a valid support for the interpretation of data

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
