La riconversione in chiave sostenibile delle infrastrutture e il problema dell’ultimo miglio
No full textSi discute oramai da tempo sul modo in cui possano e debbano essere sviluppate infrastrutture per la mobilità sostenibile o su come possano essere riconvertite quelle esistenti mantenendone la funzione, ma scarsa o nulla attenzione è dedicata alle azioni di retrofitting di sistemi di mobilità sostenibile in contesti consolidati e fortemente storicizzati, possibile incipit per azioni di rigenerazione di ambienti urbani degradati. Mutato il modo in cui devono essere guardate le infrastrutture stradali, emblema di un modello di mobilità in via di trasformazione, si vuole riflettere sul legame di reciproca influenza che esiste tra trasporti e organizzazione dello spazio urbano. Citando Jah Gehl: «prima diamo forma alle città – poi loro danno forma a noi» e «le città dovrebbero essere disegnate per le persone e non per le automobili»; si vuole delineare un sintetico quadro di interventi di riconversione in chiave sostenibile delle infrastrutture con operazioni di riqualificazione urbana nelle quali le infrastrutture stradali sono state rimodellate in funzione di un cambiamento di prospettiva: da «quante auto possiamo è possibile far passare lungo la strada» a «quante persone è possibile far muovere lungo la strada» esplorando attraverso alcuni casi esemplari lo stato dell’arte e le esperienze più innovative di riconversione delle infrastrutture in chiave sostenibile, con una particolare attenzione alle ricadute sulla qualità e sulla capacità rigenerativa di tali interventi nella citta
"Salinari per una notte" - Workshop di progettazione urbanistica: I CORTILI DI CERVIA. Lo spazio pubblico nella città storica
No full textProgetto di riqualificazione del Quadrilatero che costituisce il nucleo storico della città di Cervia che consiste nella riorganizzazione della viabilità carrabile in modo da permettere maggiore continuità allo spazio pubblico, ed in particolare per permettere la pedonalizzazione della strada lungo il lato nord ovest. Per rivitalizzare l'area oggetto di intervento viene proposta l'introduzione di una forma di albergo diffuso che coinvolga alcune delle storiche case dei salinari presenti all'interno del quadrilatero
SPADA: A Spatial Association Discovery System
No full textThis paper presents a spatial association discovery system, named SPADA, which has been developed according to the theoretical framework of inductive databases. Our approach considers inductive databases as deductive databases with an integrated inductive component and relies on techniques borrowed from the field of Inductive Logic Programming (ILP). In SPADA, an ILP module supports the processing of spatial association mining queries and accesses spatial databases via a middle-layer module for feature extraction. The resulting architecture is illustrated by commenting spatial association mining sessions in detail and showing that ILP is a viable and promising solution to the development of inductive databases
Lighting to discover the hidden Pompeii colours: the Thermopolium of Vetutius Placidus
No full textArchaeological heritage lighting is a stimulating challenge for designers. The need to find a balance between
conservation and valorisation raises several issues in terms of systems and structures compatibility, light
sources choice, light-connected damages risks prevention, security. The lighting goal in itself is hard to define:
Is the light supposed to simply guarantee monuments safe visit? Or could it dare to drive people perception,
highlighting specific details, trying to recreate original luminous environments, using scenographic effects or
emphasizing visit itineraries? These questions can have different and inventive answers depending on the
archaeological site articulation, its characteristics and its conservation status.
Pompeii is one-of-a-kind archaeological site. Excavations have brought to light an almost-intact town with its
houses, shops, theatres, temples, baths. People can come back in time and live ancient Romans life by visiting
spaces where they lived. All of this implies a particular design approach: differently from other sites, where
buildings are mostly in ruin state, in this case, lighting design is at the same time an indoor and an outdoor
design. Indeed, some buildings roofs have collapsed, others have maintained their original shape or have
been rebuilt. So, visitors continuous pass from outdoor to indoor spaces and vice versa, with the consequent
adaptation to very different vision conditions (from photopic to mesopic or scotopic one and vice versa). All
of this can create visual performance reduction (especially when the passage from a space to another is
quick), diminishing the ability in perceiving and appreciating colours, with the consequent loss of some
interesting buildings details, neglected because of the inappropriate light conditions.
Actually, in the most cases, each space of each Pompeii building hides some treasures: extraordinary frescos
of mosaics, characterized by amazing colours, unique both for their documentary and artistic value, located
all around the town, even in the most unexpected places (a cubiculum or a small shop). They should be
preserved and valued.
The paper focuses on an ancient Pompeiian thermopolium, the so called Thermopolium of Vetutius Placidus,
a sort of “snack-bar”, where hot foods and drinks were served. The space has a simple and typical structure
with a room opening onto the road (the shop) and an annexed house, but an interesting stuccoed and
frescoed lararium, representing the Lares, Mercury and Dionysus, is located in the shop and the triclinium is
decorated according to the third style.
Thermopolium lighting conditions were analysed through illuminance, luminance and spectral power
distribution measurements. Moreover frescoes colours were described by means of spectral reflectances
measurements and the chromatic coordinates under different sources were calculated. All collected data are
useful to drive technical choices in order to design the lighting system

Tradurre la “riflessività operativa”: l’insegnamento dell’antropologia medica applicata al diritto
No full textThe contribution shows how anthropological knowledge and methodology can be employed in the legal context. Although anthropology is no stranger to the legal world, light will be shed on the dynamics of its use and the ethical and positional dilemmas involved. Through an ethnographic excerpt of broader action research conducted to understand the weight of stereotypes and imaginaries in recognizing international protection, the author will reflect on the difficulties encountered in translating anthropological knowledge and methodology into the legal sphere. In particular, the author will discuss the implications of using cultural tests to interpret and validate migration stories and motivations
Effect of maternal age, height, BMI and ethnicity on birth weight: an Italian multicenter study
No full textTo assess the effect of maternal age, height, early pregnancy body mass index (BMI) and ethnicity on birth weight.To assess the effect of maternal age, height, early pregnancy body mass index (BMI) and ethnicity on birth weight. A cross-sectional study was conducted on more than 42,000 newborns. Ethnicity was defined by maternal country of birth or, when missing (<0.6% of records), by citizenship. The effect of maternal characteristics on birth weight was evaluated with general linear models. Maternal height and BMI, although not age, significantly affected birth weight. Among Italian babies, 4.7% of newborns were classified as appropriate-for-gestational age (AGA) (birth weight between the 10 th and the 90 th centile) according to the country-specific Italian Neonatal Study (INeS) charts and were re-classified as either large-(LGA) (birth weight >90 th centile) or small-(SGA) (birth weight <10 th centile) for gestational age (GA) after adjustment for maternal characteristics. On the contrary, 1.6% of Italian newborns were classified as SGA or LGA according to the INeS charts and re-classified as AGA after adjustment. Maternal ethnicity had a significant impact on birth weight. Specifically, babies born to Senegalese mothers were the lightest, whilst babies born to Chinese mothers were the heaviest. Maternal height and early pregnancy BMI, should be considered in the evaluation of birth weight. The effect of ethnicity suggests the appropriateness of ethnic-specific charts. Further studies are necessary to determine if changes in birth weight classification, may translate into improved detection of subjects at risk of adverse outcomes
β1 and β4 integrins: From breast development to clinical practice
No full textFollowing a highly dynamic and complex dialogue between the epithelium and the surrounding microenvironment, the mammary gland develops into a branching structure during puberty, buds during pregnancy, forms intricate polar acini during lactation and, once the babies are weaned, remodels and involutes. At every stage of menstrual and pregnancy cycles, interactions between the cells and the extracellular matrix (ECM) and homotypic and heterotypic cell–cell interactions give rise to the architecture and function of the gland at that junction. These orchestrated programs would not be possible without the important role of the ECM receptors, integrins being the prime examples. The ECM–integrin axis regulates many crucial cellular functions including survival, migration and quiescence; the imbalance in any of these processes could contribute to oncogenesis. In this review we spotlight the involvement of two prominent integrin subunits, β1 and β4 integrins, in cross-talk with tyrosine kinase receptors, and we discuss the roles of these integrin subunits in the biology of normal breast differentiation and as potential prognostic and therapeutic targets in breast cancer.Following a highly dynamic and complex dialogue between the epithelium and the surrounding microenvironment, the mammary gland develops into a branching structure during puberty, buds during pregnancy, forms intricate polar acini during lactation and, once the babies are weaned, remodels and involutes.

Chromatic analysis of Roman frescoes in a Pompeiian domus
No full textColours perception depends on many factors, some attributable to sources used to light the observed objects and others to the optical properties of the objects themselves and of the space they are located in. Moreover, it cannot be neglected that, as for all visual phenomena, colour perception is also influenced by observer’s psychological and physiological conditions.
Although the enhancement of colours perception is central in all lighting designs, it obviously becomes crucial in cultural heritage applications. In these cases, it is fundamental to define a proper balance between the necessity to highlight chromatic coordinates of lit artworks and to protect them by the light-connected damages, fulfilling prescriptions about maximum exposure levels [1]. The complexity of lighting design is greater when artworks are not located in museums or exhibition rooms, but are positioned in their original place and the entire architectural space must be considered a piece of art, e.g. churches or archaeological ruins. In these cases, design problems are greater: the location of luminaires is difficult because their installation must not adulterate the integrity of the cultural good; moreover, often it is not possible to access to all architectural spaces and consequently it must be considered that the artwork to lit (e.g. a fresco or a mosaic) will be observed from a specific distance and that its details will not be entirely appreciated by the observers.
In order to account all these aspects, when lighting design deals with cultural heritage the preliminary analyses are crucial. Given these premises, the goal of this paper is to present a methodology useful to scientifically characterize artworks colours and to provide a valuable tool to choose the most suitable electric artificial sources in order to highlight their chromatic properties. This methodology was used during the preliminary studies to define the lighting system for some of the most famous ancient roman frescoes: the frescoes of the triclinium of the villa of the Mysteries in Pompeii. Specifically, the analysis focused on the wall in front of the entrance of the triclinium.
It was divided in two parts: the analysis of the current lighting conditions and the chromatic analysis of fresco colours.
Daylight irradiance measurements and luminance maps were obtained to characterize the luminous environment. Then dynamic daylight simulations were performed to identify the recurring daylighting conditions inside the triclinium. The fresco was divided in several chromatic areas based on its predominant colours. Each area was characterized by means of spectral reflectance factors measurements and the chromatic coordinates of the measured samples were identified and compared
