Rinnovare le scuole dall’interno. Scenari e strategie di miglioramento per le infrastrutture scolastiche
No full textIn questo progetto di ricerca focalizzato sull'analisi, codifica e mappatura degli
elementi architettonici caratterizzanti in un'ampia selezione di progetti di edilizia scolastica
- sia di nuova realizzazione che di ampliamento dell’esistente - il tema della qualità degli
spazi interni per gli ambienti educativi si rivela e conferma come elemento centrale per la
progettazione, o riqualificazione, di architetture scolastiche in grado di rispondere alle
molteplici esigenze abitative, di comfort, accoglienza, riconoscimento e appartenenza della
comunità scolastica. La ricerca, a partire dalla mappatura quali-quantitativa di atteggiamenti
progettuali diffusi e paradigmatici, ha elaborato in prima istanza una serie di “atteggiamenti
progettuali ricorrenti” - atteggiamenti consolidati nella prassi progettuale in grado di offrire uno
sguardo proiettivo su soluzioni di interesse e parziale declinabilità - e in seguito un archivio,
online e in progress, per rendere disponibile questo reposity di progetti sulle e per le scuole
alle istituzioni scolastich
Mediterranean sea cucumbers - Biology, ecology, and exploitation
No full textThe Mediterranean Sea is the largest enclosed basin on Earth. The basin geological history, biogeography, climate, and habitat heterogeneity have generated remarkable biological diversity, rendering the Mediterranean a biodiversity hotspot. Between 40 and nearly 200 ecosystems have been identified in this basin depending on definition criteria; key among them, both in functional and structural terms, is the endemic Posidonia oceanica seagrass meadows. The meadows are an important habitat for some sea cucumber species, because they produce large quantities of seagrass debris, a preferred food source for many deposit feeders. A total of 57 species of sea cucumbers have been reported in the Mediterranean, of which 21 (37%) are likely endemic. At least six species from the Mediterranean (Holothuria forskali, H. mammata, H. polii, H. sanctori, H. tubulosa, and Parastichopus regalis) are being exploited on a basin scale or are of interest for exploitation due to their biomass and accessibility. In this chapter, for each of these species, the biology, ecology, and fishery exploitation are presented in detail. Preliminary data and considerations for responsible fisheries management are also reported, based on the Italian stock assessment program

Selected letters of Alessandra Strozzi
No full textThe letters of Alessandra Strozzi provide a vivid and spirited portrayal of life in fifteenth-century Florence. Among the richest autobiographical materials to survive from the Italian Renaissance, the letters reveal a woman who fought stubbornly to preserve her family's property and position in adverse circumstances, and who was an acute observer of Medicean society. Her letters speak of political and social status, of the concept of honor, and of the harshness of life, including the plague and the loss of children. They are also a guide to Alessandra's inner life over a period of twenty-three years, revealing the pain and sorrow, and, more rarely, the joy and triumph, with which she responded to the events unfolding around her.This edition includes translations, in full or in part, of 35 of the 73 extant letters. The selections carry forward the story of Alessandra's life and illustrate the range of attitudes, concerns, and activities which were characteristic of their author
Trophic ecology of four sympatric Mediterranean sea cucumber species and analysis of their effect on marine sediment dynamics
No full textChallenging the author: Gavin Douglas's Eneados
No full textGavin Douglas’s Eneados, a translation into the “Scottis” tongue of Virgil’s Aeneid, completed in 1513 and first published in London in 1553, presents, as well as the translation of the additional thirteenth book by Maphaeus Vegius, original prologues and marginal notes to the text, rubrics and articulate conclusive material. The present paper analyses this complex paratext as evidence of Douglas’s almost philological attention to the original and his preoccupation with a faithful reproduction; it is also suggested that the models for his organization of the commentary might be both medieval (i.e., manuscripts such as Petrarch’s Virgilius Ambrosianus) and early modern, as in the case of editions of classical works: the most apt example being Jodocus Badius Ascensius’ edition of the Aeneid, printed in 1501. The Eneados thus stands on the threshold between manuscript and print, and might have indicated new possibilities of use of the printing medium in Scotland, and of the value of the translation of a classical text, had history not intervened with the Scottish defeat at Flodden Fields in 1513, which put a temporary stop both to the circulation of the Eneados and to the development of Scottish printing
Echinoderm larvae as bioindicators for the assessment of marine pollution: Sea urchin and sea cucumber responsiveness and future perspectives
No full textEchinoderms play a crucial role in the functioning of marine ecosystems and due to their extensive distribution, rapid response, and the high sensitivity of their planktonic larvae to a large range of stressors, some species are widely used as biological indicators. In addition to sea urchins, sea cucumbers have recently been implemented in embryotoxicity bioassays showing high potential in ecotoxicological studies. However, the use of this species is still hindered by a lack of knowledge regarding their comparative responsiveness. The present study aimed to investigate the responsiveness of different echinoderm species to environmental pollution in order to develop their integration in batteries of ecotoxicological bioassays. To this end, the embryos of two sea urchins (Paracentrotus lividus and Arbacia lixula) and two sea cucumbers (Holothuria polii and Holothuria tubulosa) were incubated with inorganic and organic toxicants (cadmium, copper, mercury, lead, sodium dodecyl sulphate and 4-n-Nonhyphenol) and elutriates from contaminated marine sediments, chosen as a case study model. The results obtained, expressed through the percentage of abnormal embryos and Integrative Toxicity Indices (ITI), indicated species-specific sensitivities to pollutants, with comparable and correlated responsiveness between sea urchins and sea cucumbers. More specifically, sea cucumber larvae exposed to elutriates appear to be more sensitive than sea urchins, especially when incubated with samples containing trace metals, PCB and TBT. These results indicate that toxic responses in embryos exposed to environmental matrices are probably modulated by interactions between different variables, including additive, synergistic and antagonistic effects. These findings suggest that performing a larval test using different echinoderm classes can integrate the interactive effects of bioavailable fraction of contaminants on various levels, providing sensitive, representative and all year-round batteries of bioassays to apply in ecotoxicological studies
Towards sea cucumbers as a new model in embryo-larval bioassays: Holothuria tubulosa as test species for the assessment of marine pollution
No full textSea cucumbers are widely distributed deposit-feeders that represent an important component of benthic communities worldwide. These echinoderms were recently proposed as candidates in embryo bioassays to provide a newtool in the toxicity assessment of pollutants inmarinewater and sediments. The aimof this study is to evaluate the usefulness of a new species, Holothuria tubulosa (Gmelin, 1788), as a model organism for sensitive embryo bioassays, defining the acceptability of controls, minimum sample size, embryo density and salinity range. Cadmium (Cd), copper (Cu), lead (Pb), mercury (Hg), sodium dodecyl sulphate (SDS) and 4-n-nonylphenol (NP) were used as reference toxicants to assess specific embryotoxicity endpoints. Sea cucumber sensitivity to marine sediment elutriates were finally assessed by comparing their responsiveness in tandem with that of routinely employed sea urchin embryos. The results showed an acceptability threshold of 10% (abnormal embryos), a minimum sample size of 200 embryos, an embryo density of 200 embryos/mL and an optimal salinity range of 36–37‰. The sensitivity to the environmental pollutants and matrices tested revealed values (expressed as EC50) comparablewith those ofembryos belonging to othermarine invertebrates commonly used in bioassays, indicating that this species has a good level of responsiveness. A specific integrative toxicity index (ITI) was applied, combining the frequency of developmental anomalies and weighting their severity. ITI data demonstrated good discrimination of sample toxicity, with a dose-dependent increase of teratogenic effects for all the tested substances, indicating H. tubulosa as a promising species for future assessments of marine pollution
Nicetas Nicaenus, De azymis
No full textThe RAP online repertorium offers the first comprehensive catalogue of polemical literature related to the schism between the Roman Catholic and Orthodox Churches from the 9th to the 16th century and can be described as an ideal continuation of the *Clavis Patrum*.
Each entry identifies the work (often unpublished or newly discovered in manuscript catalogs), lists its various titles (since medieval texts often lack stable titles), provides incipit and explicit (with possible variations), and examines the manuscript tradition and foliation (by reviewing catalogs or manuscripts, verifying dates, folios, etc.). It also includes relevant bibliography (critical editions and studies), identifies the author (using prosopographical studies, dictionaries, repertories, sigillography, etc.), and provides essential biographical details. Each work is classified by literary genre (e.g., treatise, dialogue), the corresponding Byzantine term, and the main polemical themes (e.g., Filioque, Azymes, Purgatory), and is assigned a unique RAP identification number.
The Repertorium Auctorum Polemicorum is identified by the International Standard Serial Number (ISSN) 3035-2096 [continuously updated publication
