Il ninfeo di Egeria (II sec. d.C.) e la grotta degli Animali a Castello. Il ruolo del modello antico attraverso l’analisi dei disegni del GDSU
The Grotta degli Animali at the Medicean Villa in Castello is one of the most famous artificial grottoes of the 16th and 17th centuries. Its building history is quite complex because it underwent many changes, led by three different architects over a period of approximately twenty years, until its final configuration under Giorgio Vasari. The research looks into the relationship between the Florentine Grotto and its reference model: the Nymphaeum of Egeria along the Via Appia (2nd century A.D.), which was rediscovered during the third decade of the 16th century and subsequently measured by Antonio da Sangallo the Younger and Sallustio Peruzzi, whose drawings are preserved at Gabinetto Disegni e Stampe degli Uffizi (GDSU). These drawings have been analysed to provide items matching the Medicean Grotto; in particular the survey has been carried out in comparison with another anonymous drawing, representing a planimetric study for the Grotta degli Animali. The inspection of this important document (also through digital acquisition and re-elaboration) shows architectural features that are evocative of the ‘ancient model’ which was partially obliterated by Vasari’s project
Le limonaie della villa medicea di Castello e il giardino antistante la grotta degli Animali
The aim of this article is to present the new studies carried out on the “Limonaie” of Villa Castello. A part of the work concerned the investigation of the iconographic documentation kept in the State Archives of Florence, where it was possible to find important unpublished data on the design genesis of the “Limonaie” between the 18th and 19th centuries, which in the current configuration includes a greater “Limonaia” and two opposing minor “Limonaie”.A laser scanner survey campaign has also been specifically designed, involving the three “Limonaie” and the part of the garden between them. On the basis of this 3D model, plans, sections and elevations were developed and studied, obtaining new considerations on building features, decorative elements and the relationships between these architectural artefacts.The correlation of the results achieved by the archival and diagnostic investigations has cast light on the realisation of the complex of the “Limonaie”, showing its peculiarities and construction phases, and this in turn has created the knowledge base for the design of future adaptations and restorations
Atlante
In order to provide exhaustive documentation concerning the “Cave of the Animals”, the atlas is composed of already known historical documents, as well as of new historical and scientific insights. In the first case, we provide some important figurative documents, fundamental from the historical point of view, regarding a long period between the beginning of the sixteenth century and the late twentieth century. In the second case, the atlas collects results of the work carried out by the GECO Lab of the University of Florence between 2013 and 2015, which illustrates the cave's complex hydraulic system and internal decorations. Regarding the photographic documentation carried out by GECO Lab, the images are the result of the processing of many photographs for obtaining overall high-resolution images. The panoramic image showing the whole Grotto in equirectangular projection is composed of 126 photographs, whereas the images of the basins are represented in a rectilinear projection in order to preserve the straight lines as in a normal photograph using central projection
European green policy announcements and sectoral stock returns
Available online 5 May 2022To fulfill the Paris Agreement commitments and stimulated by an unprecedented amount of public resources put in place to recover from the COVID-induced recession, European governments have recently announced sizable green policy plans. In this paper, we examine the behavior of green and brown portfolios around green policy-related announcements (GPAs) made by major European governments in 2020 via a standard event study analysis and the use of returns of stocks listed in the “STOXX 100 All Europe”. Our main empirical findings indicate the presence of positive cumulative abnormal returns (CARs) both in the green and brown sectors following GPAs. However, the estimated positive sentiment effect is stronger in the former sector. A size effect in terms of the amount of resources announced to be allocated for a specific category of policy is also observed. We find that the observed positive sentiment is mainly driven by announcements on climate change mitigation-related policies, which account for 70% of the total allocated funds. At the sector level, positive and significant CARs due to GPAs are found in the (i) energy, (ii) financial and (iii) industrial sectors. At the country level, GPAs are found to drive a significant positive sentiment effect in the following European countries: Switzerland, Spain, UK, Ireland and Italy. Sector- and country-level analyses confirm the presence of larger benefits from GPAs among more sustainable portfolios
Consumers' Willingness to Pay for Quality and Safety in Clams
The aim of the research is to estimate the potential demand for certified clams in Italy and to investigate the determinants of maximum amount that respondents are willing to pay for this product. Quantitative analysis was used based on 1,067 face-to-face interviews collected in 3 Italian regions in the north bordering the Adriatic Sea (Friuli-Venezia Giulia, Veneto, and Emilia-Romagna) carried out during 2008. The consumers' willingness to pay (WTP) is measured using a contingent valuation method. In order to estimate separately the determinants of the probability that respondents are willing to pay and the maximum that they are willing to pay, a generalization of Tobit model was adopted. The results indicate that consumers are willing to pay a premium price mainly to purchase better quality products. The research provides some initial insight into consumers' WTP that can be useful for certified fish farming. © 2014 Taylor & Francis Group, LLC
Overview of Native Chicken Breeds in Italy: Conservation Status and Rearing Systems in Use
The ongoing loss of domestic animal breeds around the world is occurring at an alarming rate. Thus, the registration and preservation of native breeds is of great importance. The aim of this study, which forms part of a conservation program, was to provide an overview of the conservation statuses of native Italian poultry breeds being reared by local breeders in Italy. The data collected by means of a census questionnaire demonstrate the low population sizes of these breeds in Italy and highlight the need for campaigns aimed at publicizing and promoting the benefits of native breeds with the goal of increasing population sizes. Identifying strategies to facilitate breeders’ access to pure breed birds is also essential, and would require collaborative efforts of university research centers, public entities, and breeders
Overview of Native Chicken Breeds in Italy: Small Scale Production and Marketing
The intensive use of high-performing strains in poultry production has led to the extinction
of several autochthonous chicken breeds and, consequently, loss of genetic variability. Interest in
saving biodiversity is growing rapidly and has become a major objective worldwide. The aim of this
study was to shed light on the production trends of native Italian poultry breeds and the related
market. A questionnaire, which asked about the production cycles, the number of animals and
table eggs produced per year and their retail prices was completed by 121 breeders across Italy. The
surveyed breeders were divided into two categories: breeders conducting an agrozootechnical farm,
referred to as ‘farmers’ (F); and breeders keeping chickens as backyard poultry, referred to as ‘fancy
breeders’ (FB). Analysis of the data acquired indicated that animals were mainly slaughtered between
6 and 12 months of age, with F processing more animals per year. The same production trend was
observed for table eggs. The recorded retail prices of native chicken products were higher than
those for conventional products, but similar to those reported for valuable niche poultry products,
such as the Poulet de Bresse in France and organic eggs. Knowledge about these highly valuable
markets should be used to encourage the use of local breeds in alternative poultry farming and help
protect biodiversity
