Itinerario attraverso la ricerca più recente sullʼabitare temporaneo in Italia. Dalla rivoluzione degli anni ʼ60 al progetto per lʼemergenza degli anni ʼ80
No full textIl progetto di case prefabbricate da montare e smontare che ha caratterizzato - senza mai assumere un ruolo centrale - una parte della ricerca architettonica italiana negli ultimi decenni appartiene in realtà agli albori del secolo scorso e può costituire un punto di partenza per affrontare, in maniera diversa, le molteplici problematiche legate all’emergenza abitativa contemporanea e la riqualificazione di aree urbane dismesse.
Il saggio di Maura Percoco insieme a quello di Maria Argenti - entrambi contenuti in «Rassegna di Architettura e Urbanistica» n. 134/135 - contengono gli esiti di una ricerca intesa a ricostruire la storia delle abitazioni temporanee in Italia (dalla casa " trasportata su carri trainati da animali" della fine del secolo ai più recenti esperimenti che riutilizzano il container per il trasporto di merci), al fine di cercare in un passato più o meno recente la chiave per un futuro possibile.
In particolare, il saggio di Maura Percoco affronta l'indagine sulle sperimentazioni italiane tra i rivoluzionari anni ’60 e i meno utopici anni ’80. Da Rosselli e Zanuso a Mendini e Pea, da Spadolini a Morassutti e Pacanowski, l'esame di prototipi e brevetti progettati con componenti da montare sempre più grandi dimostrano l’evoluzione del concetto stesso di casa come "un oggetto di design, un oggetto prodotto in serie, un mobile da abitare”. Conchiglie, contenitori, monoscocche o elementi sagomati definiscono abitazioni sempre più confortevoli facili da assemblare o semplicemente da “dispiegare”.
In termini più ampi, illustrano ideali di vita, prefigurano modi informali di abitare, narrano “idee, più che soluzioni”.The design of prefabricated homes to be assembled and disassembled that characterised (without ever assuming a central role) an area of Italian architectural research during recent decades belongs in reality to the dawn of the past century and may constitute a starting point for confronting, in a different manner, the diverse problems related to the contemporary housing emergency and the rehabilitation of abandoned urban areas. The essays by Maria Argenti and Maura Percoco reconstruct the history of temporary dwellings in Italy (from the house “transportable by pack animal” from the turn of the century to more recent experiments using remodelled shipping containers), seeking the key to a possible future in the more or less recent past.
In the first of the two essays, alongside homes that could be disassembled and transported on animal-drawn carriages, we find a patent for a dismountable deco villa constructed as a prototype in Rome at the beginning of the past century. There are also experiments made by such architects as Albini, Pagano, Gandolfi, Canella, Daneri, Ponti and Minoletti. Temporary workers’ housing, dismountable vacation homes, prefabricated and lightweight houses for colonial habitats or post-war constructions that could be built in a short period of time are all described as occasions for designing and experimenting with residences, increasingly based on a logic of assembly.
The investigation of Italian experiments (from Rosselli and Zanuso to Mendini and Pea, from Spadolini to Morassutti and Pacanowski) continues in the second essay with an examination of successive projects and patents designed with ever-larger components. Shells, containers, monocoques or moulded elements define increasingly more confortable dwellings that are easier to assemble or simply to be unpacked
Health Shocks and Human Capital Accumulation: The Case of Spanish Flu in Italian Regions
No full textPercoco M. Health shocks and human capital accumulation: the case of Spanish flu in Italian regions, Regional Studies. The impact of health on economic development is a hotly debated issue in the economics literature, with most scholars supporting the idea that the diffusion of diseases is detrimental to development. In this context, pandemics are an important case study given their exogenous nature, which makes identification of the impact of diseases on development clearer than in other cases such as malaria or smallpox. This paper focuses on Spanish flu in Italy, one of the countries with the highest mortality rate due to the pandemic. By exploiting the regional variation in mortality and focusing on the hypothesis of the foetal origins of cognitive abilities, the long-run consequences of influenza exposure in terms of human capital accumulation are estimated. An average reduction of 0.3–0.4 years of schooling for the cohort born in 1918–20 is found. This result points to a small but persisting effect of health shocks on regional productivity through a variation in the rate of accumulation of human capital.</p

Digital close range photogrammetry for 3D body scanning for custom-made garments
No full textAmong several biometric applications, one of those currently attracting great interest is the possibility of carrying out 3D digitisation of human individuals to analyse their physical characteristics. These characteristics can be used for several purposes, such as security, medicine and tailoring for custom-made clothing. In recent years, although the development of online 3D scanning systems has been accelerating fast, little work has been devoted to offline systems, which would be particularly suitable for the textile and clothing industries. In the present research the author presents a specially designed low-cost offline 3D body digitiser, based on digital close range photogrammetry. A specially designed photogrammetric 3D scanner of the human body is presented, featuring automatic image processing procedures. The scanning system consists of eight cameras with a resolution of 5 megapixels, equipped with 16 mm wide-angle lenses; there are four white-light illuminators, of 100 W each. Tests on a tailor's dummy and on whole human bodies are reported, demonstrating the usefulness of the technique for textile applications. The digitisations performed on human bodies generally yield worse results than the corresponding ones on the dummy, and full body digitisations are worse than corset digitisations owing to the lower point density and to target distortion. Nevertheless, the results are satisfactory for tailoring applications that do not require high accuracies

A note on the inoperability input-output model
No full textIn this note, we propose some comments and some extensions of the inoperability input-output model (IIOM), as recently proposed by b14Santos and Haimes (2004). In particular, we propose the use of some analytic tools capable of providing information on the reaction of sectors subsequent to a terrorist attack on infrastructure service sectors. These tools, namely, the field of influence and the multiplier product matrix, provide information on the way sectors react to a shock on the aggregate demand and/or to a (temporary or permanent) change of production function coefficients. Finally, using the 2003 65 sectors input-output matrix for the U.S. economy, a simple empirical example is presented. © 2006 Society for Risk Analysis
