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

No full textCOMPOSER-LEGISLATORS IN FASCIST ITALY: DISTINGUISHING THE PERSONAL AND LEGISLATIVE VOICES OF ADRIANO LUALDI
No full textIn addition to a list of Lualdi's written works, appendices include a facing English translation of Alceo Toni, et al., “Travagli spirituali del nostro tempo: un manifesto di musicisti italiani per la tradizione dell’arte romantica dell’800,” La stampa, December 17, 1932, 3.During Italy’s fascist period, the government appointed Adriano Lualdi to the
Chamber of Deputies. The once prominent composer, author, and music critic
represented the Fascist Union of Musicians in the chamber and had roles in the
administration of government-subsidized festivals. Although little is written about the
composer-legislator, what is available depicts him as opportunistic and self-serving.
Previous scholarship claims that he used his position in the fascist bureaucracy to his own
advantage by pushing his aesthetic philosophy through legislation. These claims are
substantiated by Lualdi’s private communications and published works which detail his
opinions on musical aesthetics. Comparing Lualdi’s political records to his publications
shows that his personal opinions on aesthetics did not interfere with legislation to the
degree that past scholarship suggests. I argue that previous scholarship conflates Lualdi’s
legislative voice with his personal voice, offering a distorted, and therefore incomplete
version of Adriano Lualdi as a historical figure
Environment, biodiversity and rare species: analysis of factors affecting bat conservation.
No full textTo assess the conservation status of rare and threatened species it is necessary to have background information about their distribution, and population size and trends. While all these information are available for well-studied taxa, there is a lack of knowledge for other poorly studied species. Among Mammals, bats and rodents represent the orders with the larger than average percentage of Data Deficient species and information scarcity is one of the greatest threats to bats. The understanding and identification of key resources for bats is of vital importance for their conservation.
In the present study we analysed the main ecological requirements of some rare bat species during breeding, mating and hibernation in Varese province (Lombardy, N Italy).
The analyis of space use, activity pattern and resource selection during the breeding period was focused on a small colony of females Geoffroy’s bat (Myotis emarginatus), roosting in the town hall of a small city, through monitoring and radiotracking. The timing of birth was in the first days of July and lactation lasted for less than a month. After weaning animals abandoned the roost and in september they reached swarming/wintering sites. Geoffroy’s bat females exploited a restricted area, covering short distances during dispersion and between summer and wintering sites. Animals showed large home ranges without a centre of activity (core area), concentrating their foraging behaviour on mountain foothills on the interface between meadows and woodlands. The favourite preys were spiders, which formed three-quarters of arthropod fragments in bat droppings, followed by beetles, planthoppers, moths and mosquitoes. Lactating females appeared to use foraging areas located closer to the breeding site, although they didn’t nurse often the youngsters during the night: this may be better explained as a energy-saving behaviour during a period of high energetic constraint. Nightly activity pattern was the same for lactating and non reproductive females; they both showed an unimodal pattern, spending most of the time on the wing foraging, with a mean of 7 hours per night.
The analysis of swarming and roosting behaviour during hibernation was centered on the analysis of bat activity and the characterisation of roosts in twelve underground sites of Campo dei Fiori Regional Park through monitoring. These caves were swarming and hibernating sites for six species, one of which was the Geoffroy’s bat, a species not known to swarm. Swarming activity started at the end of August, after a rapid decrease in mean environment temperature, and peaked in September. For all species sex ratio during swarming was skewed toward males (1:3), and this bias was even stronger for Myotis emarginatus (7% females). Bat activity was highest in caves positioned at high elevation, showing large entrances, low hydrological activity and exposition toward south-sothwest. The undergroud sites most used by animals were long and deep caves or short and shallow hollows: the former show a structure and hence microclimate suited for both swarming and hibernation, while the latter should be less fit for hibernation due to poor conditions of isolation from the athmosferic agents.
Underground sites are key resources for bats, in relation to breeding, mating and hibernation, and their uneven distribution on the territory makes them used by a large number of bats that gather from a vaste area. In addition, bats show a high fidelity to single roosting sites, therefore the loss or deterioration of underground sites can result
in a complete loss of suitable roosting place at a large scale, thus affecting different bat populations that could be subject to a decrease and a genetic deterioration.
The two most abundant species in the caves of Campo dei Fiori Regional Park (Myotis emarginatus and M. nattereri) showed a positive trend during the last 11 years. This increase may be due to the protection efforts that has been put in bat conservation, but a longer data set is required to discern natural population fluctuations from real trends.
The understanding of ecological requirements of rare and threatened species is imperative for the enhancement of effective conservation programs and the identification of features that affect bat choice of roosts is important to make predictions about the areas suitable for bat presence in order to concentrate our efforts in identifying new important roosting areas

No full textFactors underlying migratory bat aggregations in chestnut groves
No full textDeciduous woodlands have undergone major structural changes in Europe in the course of the last century. Dense woodlands have, for instance, replaced traditionally managed, open sweet chestnut groves, and have led to biodiversity losses. Surveys carried out in the southern Alps have shown that the frequency of occurrence of the rare migratory Leisler’s bat Nyctalus leisleri in bat boxes is much higher in managed than in unmanaged chestnut groves, pointing to the importance of traditional groves as stopover sites. To identify the reasons for this habitat preference we investigated whether managed chestnut groves constitute a more appropriate foraging ground than closed stands, and whether bat boxes in managed chestnut groves offer more suitable temperature conditions for roosting. Foraging habitat selection and roost usage were investigated by means of radiotracking and temperature loggers, respectively. Foraging Leisler’s bats predominantly selected deciduous woodlands over other habitat types, but showed no distinct preference for either type of chestnut grove over other forest types. In managed chestnut groves, bats used cooler boxes than others available in the same habitat, but there was no difference in temperature between the boxes used in managed versus unmanaged groves. Our results provide no evidence that foraging opportunities or roost temperature dictate the forest-specific pattern of bat box occupancy. As an alternative explanation, we suggest that managed chestnut groves may represent optimal lekking arenas due to their open structure and high roost density. Whatever the reason for this habitat preference, partially maintaining traditional management, resulting in a semi-open, mosaic landscape, is likely key to maintaining chestnut groves attractive for this migratory bat
Tilgher Adriano
No full textDopo un primo accostamento all’idealismo fichtiano, Adriano Tilgher elaborò una concezione della filosofia come tensione irrisolvibile tra opzioni morali e visioni del mondo, rifiutando ogni totalità sistematica. Sul piano religioso, per Tilgher il problema fondamentale di ogni religione è il problema del male: di fronte ad esso, se il buddismo ha proposto di fuggire il mondo, il cristianesimo «ha sempre considerato il mondo, la vita, la società come campi di combattimento e preparazione del cielo». Le soluzioni religiose tradizionali, compreso il cristianesimo, sono, però, afferma Tilgher, in grave crisi, dato l’indebolimento della credenza nell’involucro mitico che le sosteneva, ma il tema del male resta non certo meno pressante del passato e l’autore si mostra estremamente critico anche con le ideologie politiche che hanno preteso di sostituire le tradizioni religiose, non certo risolvendo e anzi aumentando ancora l’entità del male.
Parole chiave: Adriano Tilgher, problema del male, dramma del cristianesimo, mito e religione, anti-totalismo
After an initial approach to Fichtean idealism, Adriano Tilgher developed a conception of philosophy as an irreconcilable tension between moral options and worldviews, rejecting any systematic totality. On a religious level, for Tilgher, the fundamental problem of every religion is the problem of evil: in the face of it, while Buddhism has proposed to escape the world, Christianity "has always regarded the world, life, and society as fields of battle and preparation for heaven." However, traditional religious solutions, including Christianity, are, Tilgher asserts, in serious crisis due to the weakening of belief in the mythical framework that supported them. Yet, the theme of evil remains no less pressing than in the past, and the author is extremely critical of political ideologies that have sought to replace religious traditions, which have not resolved the issue but rather exacerbated the extent of evil.
