This paper reviews selected evidence of environmental changes in the central Canadian Rockies during the 20th century. The instrumental climate record shows that mean annual temperatures have risen ca. 1.4°C over the last 100 years but seasonal patterns of change are complex. The greatest increases have been in winter temperatures (3.2°C / century). Precipitation data, though limited, show variable patterns of change on decadal scales with generally higher levels of precipitation in the mid-20th century. The longest streamflow record also shows considerable variability, with highest flows in the 1950s. A tree-ring-based temperature reconstruction indicates summer and spring temperatures in the last half of the 20th century are higher than any equivalent period over the last 900 years. Although no accurate regional estimates exist, glaciers have probably lost ca. 25% of their area in the last 100 years and may be smaller now than they have been at any time in the last 3000 years. These two lines of evidence suggest that the climate of the late 20th century is exceptional in the context of the last 1000 to 3000 years. Small but significant vegetation changes are taking place at the upper treeline ecotone in response to climate changes over the 20th century (e.g., seedling establishment). However, the most significant landscape change in the last 100 years is the transformation of the character of the montane forest due to a reduction in forest fire frequency, largely due to an active policy of fire suppression. Dans cet article, on révise certaines manifestations des changements environnementaux qui se sont produits dans les Rocheuses canadiennes au cours du 20ème siècle. Ce registre instrumental climatologique indique que les moyennes annuelles de température ont augmenté d'environ 1,4°C en 100 ans, mais les modèles de changements saisonniers sont complexes. Les plus fortes augmentations ont été notées dans les températures hivernales (3,2°C/siècle). Les données concernant les précipitations - bien que limitées - indiquent des tendances variables de changement selon les décennies et en général des niveaux plus élevés de précipitation au milieu du 20éme siècle. Le plus long enregistrement des débits d'un cours d'eau indique aussi d'importantes variations, les débits les plus forts se situant dans les années 1950. La reconstruction des relevés des températures faite à partir des cernes montre que les températures estivales et printanières de la deuxième moitié du 20ème siècle sont plus élevées qu'elles ne l'étaient durant les périodes correspondantes des 900 dernières annés. Même s'il n'existe aucune donnée règionale exacte, les glaciers ont probablement perdu à peu près 25% de leur superficie au cours du dernier siècle et ils ont atteint leur plus petite taille des 3000 dernières années. Ces deux preuves suggèrent que le climat de la fin du 20ème siècle est exceptionnel dans le contexte des 1000 à 3000 dernières années. Des changements mineurs mais significatifs s'effectuent actuellement dans l'écotone supérieur de la limite des arbres à cause des changements climatiques du 20ème siècle (ex. l'implantation de nouvelles pousses). Pourtant, pendant le dernier siècle, la transformation la plus significative s'est effectuée dans les forêts de montagne. Grâce à une politique active de suppression des incendies de forêt, ceux-ci sont beaucoup moins fréquents.  相似文献

Juan Antonio Llorente's edition of Bartolomé de Las Casas's writings, Colección de las obras del venerable Obispo de Chiapa, Don Bartolome de las Casas, defensor de la libertad de los Americanos, illustrates how Las Casas was perceived and condemned in the early decades of the nineteenth century. In this article, I seek to explain why and in what ways Bartolomé de Las Casas's early propositions on African slavery played a fundamental role in Juan Antonio Llorente's edition of Colección, an ambitious editorial work that involved much more than selection, editing, and publication. By approaching the Colección's production and reception from the perspective of book history, I explore how Llorente's Colección reflects the role that colonial affairs and race had in the challenges faced by European rule and white hegemony.  相似文献

This article looks at one of the more obscure moments in British constitutional history, the rise of federal devolution in the United Kingdom in the early 20th century and, in particular, the context to the Conference on Devolution that sat between October 1919 and April 1920. The conference, as this article will briefly discuss, has been relegated to footnote status in the historiography on federal devolution and British politics. However, while the conference has not been the subject of detailed academic attention, the claim that devolution and constitutional reform in this period was a by‐product of the crisis in Ireland pre‐partition has gathered considerable traction among political historians. This article will redress both the paltry analysis of the Conference on Devolution within the academic literature and the Irish‐centric historiography on federal devolution in the early 20th century. On the latter front, this article will demonstrate that the conference was the product of forces that extended beyond the Irish crisis, in particular parliamentary congestion. As for the conference itself, this article will use a wide range of archival sources to examine critically the conference's deliberations and in doing so will challenge prevailing assumptions regarding the supposedly one firm source of agreement during the conference: the powers that the devolved bodies should enjoy.  相似文献

The heritage of 1789 left French politicians and political analysts with the complex task of reconciling the two antithetical ideals of the Revolution: the desire to make the nation the sole political arbiter through its representatives with the need to maintain its unity. The history of France from 1789 to de Gaulle reflects France's fearfulness toward a strong executive as well as its fundamental mistrust in the people's capacity to maintain the cohesion of the nation and serve the general will. Here it is argued that de Gaulle overcame these contradictions by retaining French liberalism's emphasis on a dual executive, while the Bonapartist ideal of a strong executive could, erroneously, appear to be de Gaulle's deliberate choice. Finally it is argued that 'cohabitation', the debate surrounding the duration of the presidential mandate and the changing attitude toward France's relationship to the Vichy regime, reveal transformations proper to the French state in the late 20th century as much as a crisis of Gaullism and the loss of its basic meaning.  相似文献

This paper examines a tradition of eusocial insect research stemming from the Austrian zoologist Karl von Frisch. As I show in this paper, one of the most enduring features of the Frischean tradition has been an experimental methodology developed by Frisch in the early 1910s. By tracing this methodology's use through Frisch's student, Martin Lindauer, and two of Lindauer's students, Rüdiger Wehner and Randolf Menzel, this paper illuminates a surprising aspect of ethology's development during the last half of the 20th century. Namely, it sheds light on how the Frischean tradition, a tradition that had a complicated relationship with ethology since the discipline's formation in the 1930s, produced scientists who became leading figures in neuroethology, the most prominent contemporary field of behavioral research to retain the label of “ethology.” Some of the features that distinguished Frisch's training method from the program of classical ethology and the work of his contemporaries later helped his academic descendants adapt the method to the neuroethological program.  相似文献

Abstract. Paris was the unrivaled capital of modern art in the nineteenth century, but during the early twentieth century major innovations began to be made elsewhere in Europe. The author examined the careers of the artists who led such movements as Italian Futurism, German Expressionism, Holland's De Stijl, and Russia's Suprematism. Quantitative analysis revealed the implications of the conceptual basis of the art of Umberto Boccioni, Giorgio de Chirico, Kazimir Malevich, and Edvard Munch, and of the experimental origin of the innovations of Wassily Kandinsky, Paul Klee, and Piet Mondrian. The finding that the invention of abstract art was made nearly simultaneously by the conceptual Malevich and the experimental Kandinsky and Mondrian particularly indicates the importance of both deductive and inductive approaches in the history of modern art.  相似文献

ABSTRACT. This article focuses on the strategies Finnish women used to influence their status and the missionary practices in the Japan mission of the Lutheran Evangelical Association of Finland during the early part of the 20th century. Women had a head-start in the mission compared to men but lost this later as the organization developed. However, the early years demonstrate how women were able to gain a foothold simply by exceptional circumstances, such as a political turmoil. The crisis years of the Finnish mission in the early 1910s illustrate how organizational rigidity was created at the cost of women's status, but also that everyday work carried out separately from the men's work offered women satisfactory roles regardless of the patriarchal structure. An additional strategy is introduced by the career of one missionary, Siiri Uusitalo. A lifelong career in the mission and a pioneer's status enabled Siiri Uusitalo to carve out an independent position inside the Finnish mission which can be defined as matriarchal. Through the Finnish female missionaries, the contested male control of the mission in the Japanese context is discussed. The article presents one historically unique case that nevertheless points to certain patterns in contesting and redefining the gendered hierarchy in a religious community amidst a foreign culture.  相似文献

Much of the recent Australian security studies literature has focused on contemporary challenges to Australia's role in Asia, the evolving trajectory of defence strategy, and the various factors that have shaped the nation's ‘discourse of threats’. While this body of work is important and valuable, there is a distinct lack of scholarship that discusses the types of future security threats likely to confront Australian policy makers in the twenty-first century. Indeed, there is a tendency among scholars to assume that this sort of ‘futures’ work is best left to those outside the academy. I argue, however, that it is an area which is too important to leave to the authors of defence White Papers, think tank reports, and classified strategic assessments. Australia's future security environment in a complex international system has not been subject to the sort of systematic scholarly analysis the topic merits. This article seeks to provide a stepping stone for more substantial work in the area and outlines a conceptual framework that can aid us in understanding the factors likely to impact on Australia's security environment in the early part of the twenty-first century.  相似文献

Abstract

A watermill is known to have existed on the river Gade since the 11th century on the site of Nash Mills, Hertfordshire, where a purpose-built paper mill was constructed in the late 18th century. In 1810 the mill was purchased by John Dickinson, one of the great innovators of the paper industry. The mill evolved significantly during the 19th and early 20th centuries as part of Dickinson's expanding business, which at one stage comprised five mills in the locality. Nash Mills remained in the ownership of John Dickinson and his successors until 1990, ceasing production in 2006, the last of Dickinson's mills to do so. Using documentary and building evidence, this article examines the development of the mill, emphasising the relationships between personalities, events, structures, processes, and changing business and technological influences.  相似文献

The present study focuses on the biography and artistic heritage of S.I. Borisov, one of Barnaul's most successful photographers of the early 20th century. Borisov's archive is kept at the Altai State Museum of Local Studies and includes materials from his photographical expeditions to the Altai in 1907–1914. The analysis of the photographs given here creates an image of this multiethnic region as it was at that time in all its diversity of culture and tradition.  相似文献

Previous fur trade scholarship has emphasized the hunting of fur bearers and large game rather than fishing as a component of trade relations with native peoples in the northwestern interior of North America. Evidence from fur trade records of the 18th and 19th centuries clearly indicates the importance of the Rainy River sturgeon fishery to Ojibway subsistence and commerce. In addition to being a major food resource, sturgeon provided the Ojibway with a substance called isinglass, which was traditionally important and was also a marketable commodity. Derived from the air bladder of sturgeon, isinglass was highly valued in the European market. The Hudson's Bay Company took great efforts to secure supplies of isinglass from native fishermen. Analysis of isinglass returns from Hudson's Bay Company account books reveals the magnitude of sturgeon production from the Rainy River area. During the fur trade period, the sturgeon fishery was a highly productive industry, characterized by a sustained annual yield. With the advent of non-native commercial fisheries in the region, production increased beyond the level of sustained yield. This resource was virtually destroyed by the early 20th century. Les recherches antérieures consacrées au commerce des fourrures ont fait ressortir la chasse d'animaux à fourrure et de gros gibiers plutôt que la pêche cornme activité importante dans les relations comrnerciales avec les autochtones vivant à I'interieur du Nord-Ouest de I'Amériyue du Nord. Les documents touchant le commerce de la fourrure dux 18e et 19e siècles démontrent nettement l'importance de la pêhe aux esturgeons dans la riviéere Rainy pour les Ojibways dans leur vie et leur commerce. En plus de constituer une irnportante res-source alimentaire, l'esturgeon offrait aux Ojibways une substance appelée ichtyocolle qui avait une importance traditionnelle et représentait également un produit négotiable. Ce produit, provenant de la poche d'air de l'esturgeon ètait très estimè sur le marché européen. la compagnie de la baie d'Hudson s'est efforcée de s'ap-provisionner en ichtyocolle auprès des pêcheurs indigènes. Les livres de comptabilitè de la compagnie de labaie d'Hudson révèfent l'importance de la production d'esturgeons dans la région de la rivière Rainy. Au cours de la période du commerce des fourrures, la pêhe d'esturgeons était une industrie très productive, caractérisée par un rendement annuel soutenu. Avec I'arrivée dans la région de la pêche commerciale non-autochtone, la production a dépassé les niveaux de rendements support-ables. Cette ressource s'est trouvée virtuellement dé-truite au début du xxe siècle.  相似文献

‘Brigadoon’ is an American musical comedy of the 1940s and early 1950s. The story centres on a village called Brigadoon, in the Scottish Highlands. Two hundred years ago Brigadoon was threatened with an influx of witches. The village priest, fearing the evil of the influx, prayed that God would so change Brigadoon that one night in the village would last one hundred years in the outside world. Thus, to outsiders, Brigadoon appears only one day each century. Brigadoon would thus survive, each centennial appearance being so brief, in the priest's opinion, that the outside world would not affect it. Brigadoon is a picture-postcard ‘traditional Highlands village’: Highland cattle, milk-maids, village fairs, kilts, tartans, clans and bagpipe music overwhelm the audience. In ‘The invention of tradition: the Highland tradition of Scotland’, Hugh Trevor-Roper (1983) demonstrates that the marks of Highlands culture so pronounced in Brigadoon were a late creation. The kilt was invented by a Quaker English ironmaster from Lancashire, Thomas Rawlinson, around 1730; the image of a distinctive Highlands culture was the creation of James McPherson and the Reverend John McPherson in the 1760s; the distinctive clan tartans were created and marketed by cloth merchants in the late 18th and early 19th century, especially the firm of William Wilson & Son, of Bannockburn, and especially in preparation for the visit of George IV to Edinburgh in 1822.  相似文献

Excavation of an underwater site on Al Hallaniyah Island, Oman, conducted from 2013 to 2015, confirmed the presence of at least one early 16th‐century shipwreck. The location is believed to be where Vincente and Brás de Sodré’s Esmeralda and the São Pedro, both part of Vasco de Gama's second voyage to India, were wrecked in 1503. This article describes the ceramic and other domestic material assemblage. It is a study of the objects used by sailors on board in their daily lives. The non‐European ceramics also give indications of supplies, cargoes, and plunder acquired during the voyage. These aspects of the assemblage provide two different perspectives on the new era of maritime global trade.  相似文献

Circumstances were auspicious when George III came to the throne in 1760, but soon his political actions were much criticized and he was accused from early in his reign until well into the 20th century of weakening the independence of parliament and undermining the constitution. Some contemporaries did defend him and these views received powerful support from Sir Lewis Namier and his followers in the 20th century. Both interpretations have their flaws, however, because of the failure to recognize the profound changes in the context in which George acted over his long reign and the subtle changes that occurred in Britain's unwritten constitution over that half century. By examining how the king appointed and dismissed ministers, sought to influence the composition of both houses of parliament, and endeavoured to shape government policy, this article seeks to revise our understanding of the king's relations with parliament and the constitution and to relocate our overall assessment of him between those offered by his many critics and defenders both during his reign and long afterwards.  相似文献

During the Tudor period the Speaker was nominated by the crown. The house of commons acquiesced with the crown's nomination, but not entirely passively. There is a body of evidence suggesting that the crown's nominee became the focus of disapprobation once his name became known. What hostility there was to the Speaker-designate from the mid 16th century was displayed to better effect outside the House than within.  相似文献

Abstract

Very little site-oriented dendrochronology has been undertaken in Scotland, possibly because of the absence of a locally based dendrochronological facility until recently. However, timbers found during the excavations of several medieval burghs in the late 1970s and 1980s were saved for future analysis and had been stored in museums around the country. During a project to locate suitable samples fir a Scottish tree-ring database the potential of these assemblages was recognised. Although relatively small assemblages, their analysis has expanded and strengthened the tree-ring database within Scotland, thus facilitating future work. Evidence fir synchronous development in the early burghs in the late 12th century and the nature of the woodland resource at times during the medieval period is presented. An 'event horizon' in the early 10th century, signalled by the birth dates of marry of the dated timbers, has been recognised and possible causes are discussed. The projects reported on here were all funded by Historic Scotland.  相似文献

Since the arrival of Dutch colonists in the Cape of Good Hope, South Africa, Khoesan populations were subjected to severe political and economic marginalisation and often fell prey to racial conflict. These circumstances persisted until the early 20th century, during which an astonishing number of Khoesan skeletons were transported from South Africa to various locations in Europe, as at the time, different institutions competed to obtain these remains. The purpose of this study was to assess the health status of the late 19th and early 20th century Khoesan. Skeletal remains housed in two different European institutions were studied. The sample comprised 140 specimens from the Rudolf Pöch Skeletal Collection in Vienna, Austria, and 15 specimens from the Musée de l'Homme in Paris, France. These individuals represent both sexes and were aged between newborn and 75 years, with 54 being younger than 20 years of age. Results indicated high levels of typical disease conditions associated with groups under stress, such as periostitis, cribra orbitalia and porotic hyperostosis. Treponemal disease, rickets, osteoarthritis and trauma were also encountered amongst other more specific indicators of health and disease. This study provided additional knowledge on the health status and lives of the Khoesan people during this turbulent period and created new awareness regarding a group of severely mistreated individuals.

20世纪中国的四次实证史学思潮   总被引:4,自引:0,他引:4  
中国20世纪共经历了四次实证史学思潮:世纪初的“为历史而治历史”思潮,二三十年代的“把历史学语言学建设得和地质学、生物学等同样’’的新历史考证学,80年代初的“回到乾嘉时代”,90年代的“振兴国学”与“南北二陈”。四次实证史学思潮各有其特点和现实针对性,而学科化建设和科学化道路则是贯穿20世纪中国史学始终的两大主题。但是,考据毕竟只是手段,不是目的,实证史学已经不能适应社会变革和学术发展对历史学的要求。  相似文献

This article is based on mixed‐method field research in Adimalathura, a coastal village in south Kerala, India, which has been identified as one of the poorest communities in the area. Although this fishing community has been facing severe ecological challenges, including massive resource depletion, it has been able to put up stiff resistance to impending dispossession in the face of a large port project actively promoted by the government, most major political parties and globalized capital. This article traces the history of public action and work in Adimalathura since the early 20th century, and reflects on its significance in the context of the present resistance. It examines the role of women in bolstering the community in times of severe challenges to men's livelihoods, and highlights the importance of women's provisioning work. Ultimately, the author cautions against exaggerating community strength and the capacities of the women even when they are able to utilize available resources competently.  相似文献

Abstract

Excavations on this site, undertaken by Paul Logue for EHS: Built Heritage DOE: NI, produced evidence for at least two phases of occupation outside Bishop's Gate, Londonderry during the 17th century. This occupation came to an end with a phase of activity dated to the commencement of the Jacobite siege in A.D. 1689. Further evidence of that siege was uncovered in the form of a ravelin ditch 2.8 m wide and 0.57 m in depth, constructed in early 1689 to front Bishop's Gate. The extant remains of a sally port interrupted the ditch. A nearby larger ditch, scarped from the sloping ground outside Double Bastion, measured a maximum of 8.4 m in width and 1.4 m in depth. This larger ditch may have been part of efforts to improve the City defences in the wake of the 1641 rebellion. Further evidence of conflict archaeology was recovered in the form of lead shot, weapon furniture and flint gunspalls.  相似文献
