La memoria risorgimentale in Giustizia e Libertà (1929-1940)

The dissertation regards The memory on the Italian Risorgimento in “Justice and Freedom”(1929-1940) a theoretical core point in the history of the Movement, which so far has not been granted due attention. The work herewith presented is therefore aimed at filling a storiographical gap, analysing the historical events which continue to operate as traditions, raising feelings and passions and hence operating in politics, although as secondary factors. The point made is that the Justice and Freedom Movement, an antifascist political movement born in Paris in October 1929, bases its strength on the heroic choice of the antifascism movement to fight a Second Risorgimento, connecting the fight against the regime to the battles previously fought for the justice and the freedom, an entirely isolated event in the political opposition’s panorama. The dissertation, thus, attempts to explain how and why Justice and Freedom is so tightly interconnected in its political action to the Risorgimento tradition. The first chapter sets the cultural background of the foundation of the Justice and Freedom Movement. The centre of such foundation was Florence, where Gaetano Salvemini, along with a group of young people, would later on carry out some cultural experiences that ideally prepare the ground for the movement’s birth. In the second chapter are found the sites of the memory where the passage of the Risorgimento tradition between the generations takes place. The work therefore shifts from a public to a private level, concentrating on biographical paths. The choice made was for Nello Rosselli, a man very close to the Justice and Freedom Movement but who, as opposed to his comrades-in-arms, did not chose the political way to express his ethical choice, but rather the theoretical one, becoming a Risorgimento historian. The third chapter concentrates on the birth of the Justice and Freedom Movement in France, trying to reconstruct the cultural ties and the confrontation places and sites where the members of the Movement could interact with the French intellectual milieu, bringing back to light the propagandistic usage of the Risorgimento myth carried out by the Movement. Lastly, the fourth chapter focuses on the cultural debate on the Risorgimento, which took place on the press organs of the Movement, pointing out and periodizing the theoretical passages and the propagandistic uses of the myth as related to the stages of the Movement and the political needs.

La costruzione moderna a Bologna 1920 - 1940

Il presente lavoro di ricerca si inserisce all’interno degli ambiti di interesse del settore disciplinare dell’ICAR 10 – Architettura Tecnica, rappresentato dalla Storia della costruzione. In questo quadro, lo studio sulla Costruzione Moderna a Bologna tra il 1920 e il 1940, costituisce un tassello di una ricerca più ampia ed intesa a delineare l’importanza assunta dalla vicenda bolognese nel definire il profilo teorico ed applicativo della tecnica in cemento armato nella genesi del linguaggio architettonico che connota l’esperienza del Modernismo italiano degli anni trenta. La ricaduta più diretta della ricerca è rintracciabile nella creazione di una base informativa ipertestuale strutturata secondo diversi livelli di lettura tra loro correlati: la localizzazione, i progettisti e le imprese costruttrici, l’anno di realizzazione, la tipologia, le tecniche costruttive impiegate, la storia dell’edificio, le trasformazioni, la localizzazione della documentazione e le fonti bibliografiche, con collegamenti ipertestuali che consentono di consultare il materiale documentario. Gli esiti di tale studio hanno una duplice finalità: da un lato tale lavoro restituisce una mappatura analitica del patrimonio edilizio costruito nel ventennio analizzato, consentendo una registrazione sintetica ma puntuale delle fonti archivistiche e dei relativi apparati documentali. Un lavoro di supporto indispensabile per ogni futura ricerca intesa ad indagare le singole vicende che hanno accompagnato lo sviluppo edilizio della città di Bologna. In seconda istanza questo studio consente di porre in luce l’importanza assunta dai magisteri tecnici nel definire le scelte di ordine architettonico, ovvero di evidenziare come la conoscenza della storia materiale degli edifici induca a formulare una valutazione più appropriata e stringente sugli esiti architettonici conseguiti, superando così l’astrattezza di una interpretazione votata ai soli aspetti figurativi.

Charles P. Daly's Gendered Geography, 1860-1890

The American Geographical Society (AGS) serves as a case study for considering the nature of “gendered geography” in the nineteenth-century United States. This article links the ideals and programmatic interests of the society—which were fundamentally commercial in nature—with the personal subjectivity of its chief protagonist, Charles P. Daly, AGS president from 1864 until his death in 1899. Daly is presented as an “armchair explorer” who shifted the focus of the society away from statistical representations of the world toward the action packed narrative descriptions of the world supplied by embodied explorers in the field. The gender dynamics associated with the center versus the field provide a useful way to contrast both sides of Daly’s persona—as a scholar performing detached, careful study yet someone who also derived a great deal of personal authority by staging popular and dramatic spectacles in New York City, speechifying and presenting himself on stage at geographical society meetings with returning heroic explorers. Daly not only served as New York’ smost influential access point to the Arctic at the time, he also served as an important node in the reproduction of masculine culture in promotion of a particularly masculinist commercial geography. Key Words: American Geographical Society, Charles Patrick Daly, gender and geography, history of geography, masculinity.

Civic Discipline: Geography in America, 1860-1890

Civic Discipline argues that the story of the origins of American geography is a distinctly "New York story." Wealthy businessmen began America's first geographical society - the American Geographical Society - in 1851, inspired by what geographical knowledge of the globe could offer an expanding American commercial Empire at home and abroad. AGS meetings were spectacularly popular among the public and press. At them, geography was cast as a science in the service of the public and civic good. Meanwhile though, AGS men's spatial and financial "missions" became closely linked. They helped improve derelict spaces in New York City and weighed in on controversial scientific questions of the day in the Arctic, yet the geographical knowledge they advanced - such as in the American West and in Central Africa - also created enormous personal wealth. Civic Discipline shows that it was not just that historical events shaped geography, but rather, that geography shaped historical events.

Recent increase in black carbon concentrations from a Mt. Everest ice core spanning 1860-2000 AD

A Mt. Everest ice core spanning 1860–2000 AD and analyzed at high resolution for black carbon (BC) using a Single Particle Soot Photometer (SP2) demonstrates strong seasonality, with peak concentrations during the winter-spring, and low concentrations during the summer monsoon season. BC concentrations from 1975–2000 relative to 1860–1975 have increased approximately threefold, indicating that BC from anthropogenic sources is being transported to high elevation regions of the Himalaya. The timing of the increase in BC is consistent with BC emission inventory data from South Asia and the Middle East, however since 1990 the ice core BC record does not indicate continually increasing BC concentrations. The Everest BC and dust records provide information about absorbing impurities that can contribute to glacier melt by reducing the albedo of snow and ice. There is no increasing trend in dust concentrations since 1860, and estimated surface radiative forcing due to BC in snow exceeds that of dust in snow. This suggests that a reduction in BC emissions may be an effective means to reduce the effect of absorbing impurities on snow albedo and melt, which affects Himalayan glaciers and the availability of water resources in major Asian rivers.

Radiocarbon analysis in an Alpine ice core: Record of anthropogenic and biogenic contributions to carbonaceous Radiocarbon analysis in an Alpine ice core: Record of anthropogenic and biogenic contributions to carbonaceous aerosols in the past (1650-1940)

Long-term concentration records of carbonaceous particles (CP) are of increasing interest in climate research due to their not yet completely understood effects on climate. Nevertheless, only poor data on their concentrations and sources before the 20th century are available. We present a first long-term record of organic carbon (OC) and elemental carbon (EC) concentrations – the two main fractions of CP – along with the corresponding fraction of modern carbon (fM) derived from radiocarbon (14C) analysis in ice. This allows a distinction and quantification of natural (biogenic) and anthropogenic (fossil) sources in the past. CP were extracted from an ice archive, with resulting carbon quantities in the microgram range. Analysis of 14C by accelerator mass spectrometry (AMS) was therefore highly demanding. We analysed 33 samples of 0.4 to 1 kg ice from a 150.5 m long ice core retrieved at Fiescherhorn glacier in December 2002 (46°33'3.2" N, 08°04'0.4" E; 3900 m a.s.l.). Samples were taken from bedrock up to the firn/ice transition, covering the time period 1650–1940 and thus the transition from the pre-industrial to the industrial era. Before ~1850, OC was approaching a purely biogenic origin with a mean concentration of 24 μg kg−1 and a standard deviation of 7 μg kg−1. In 1940, OC concentration was about a factor of 3 higher than this biogenic background, almost half of it originating from anthropogenic sources, i.e. from combustion of fossil fuels. The biogenic EC concentration was nearly constant over the examined time period with 6 μg kg−1 and a standard deviation of 1 μg kg−1. In 1940, the additional anthropogenic input of atmospheric EC was about 50 μg kg−1.
