This article examines the origin, development and controversies concerning the 'Manifesto of racial scientists', the document published in July 1938 that laid the foundations for the forthcoming racial policies of the Fascist regime. The article seeks to explain Mussolini's rationale for adopting a racial ideology in the first place, and for including within this ideology such diverse (and contradictory) concepts as the 'Nordic Aryan' racial identity of Italians; the 'purity and uniqueness' of the 'Italian' race; anti-Semitism; anti-Africanism; and a 'biological' definition of race. These concepts, in general alien to traditional Italian thought, provoked a backlash among some prominent Italian scientists and Fascists of such magnitude as to throw the entire program of racial propaganda in disarray for the remainder of the regime's existence. The article also highlights the career of Dr Guido Landra, the actual author of the Manifesto, and considers the extent to which his ideas influenced the text. Questo articolo esamina l'origine, lo sviluppo e le controversie relative al Manifesto degli Scientisti Razziali. Il documento fu pubblicato nel luglio del 1938 e fornì la base ideologica per i successivi programmi razziali del regime fascista. L'articolo tenta di illustrare il motivo principale per cui Mussolini adottÒ un'ideologia razziale e incluse in tale ideologia concetti diversi e contraddittori come l'identitÀ razziale "Ariano-Nordica" degli Italiani; l'eccezionalitÀ e la pureza della razza italiana; l'antisemitismo; l'anti-Africanismo; e una definizione biologica del concetto di razza. Questi principi, che in generale sono contrari agli ideali comuni italiani, provocarono un contraccolpo, in grande scala fra molti scientisti italiani di fede fascisti e portarono il programma di propaganda razziale a uno stato di confusione per il resto dell'esistenza del regime. L'articolo esamina anche la carriera del dottor Guido Landra, il vero autore del Manifesto, e considera fino a che punto le idee di Landra influenzarono il contenuto del testo.  相似文献

ABSTRACT

Many communities rely on tourism spending, so it is important to understand any potential changes to tourist flows resulting from changing climate and weather patterns. However, tourists are not a homogenous group, as they have different motivations, values, and goals. Therefore, the purpose of this investigation is to better understand potentially varying perceptions and behavior of different tourist types, specifically in regards to their weather sensitivity, climate change concern, and behavioral intention for climate change mitigation. Tourists were randomly surveyed at 20 locations throughout the state of Maine in the United States (n = 704). Segmentation analysis on the activities tourists participated in yielded three segments of Maine tourists: non-nature-based tourists (50.6%), nature-based generalists (16.2%), and nature-based specialists (33.2%). Differences across segments were explored for perceptions of weather impacts, climate change concern, and mitigation intent. Additionally, weather sensitivity was analyzed based on type of overnight accommodations to better understand if this also had a role in differences. Non-nature-based tourists thought that weather variables were less influential during their travels in Maine than the other segments, while nature-based generalists perceived weather to have the highest influence. Additionally, nature-based specialists had the highest level of climate change belief, while nature-based generalists had the highest willingness to engage in climate change mitigation behavior. Results are useful to understand how segments of tourism demand may be altered with a changing climate, such as increased temperatures, precipitation, and storms, and what groups may be the most beneficial to target for marketing or educational efforts to reduce the impact of climate change.  相似文献

This article examines the journey to the Mongol court by the Franciscan William of Rubruck and his unsuccessful attempts to negotiate his way through the Mongol hierarchy with gifts of food. Using William of Rubruck’s account of his journey, the Itinerarium, this article analyses the utility of gifts of food across different cultural contexts. Rubruck ultimately gained status among the Mongols through his ‘gift of self’, demonstrating how social standing can be negotiated through finding the appropriate cultural grammar for gift giving. Pervasive western medieval views on gift giving were not uncontested: alternate views of what constituted a gift existed within the broader thirteenth-century world.  相似文献
