This paper presents the findings arising from neutron activation analysis (NAA) of northern Chilean domestic ceramic samples from Caleta Vitor (n = 38) and clay samples (n = 15) from nearby valley, coast and highland contexts. This study presents the first NAA data set of ceramics spanning a temporal period of 1500 years (c.2000 to c.476 bp ) from the Vitor Valley as well as the first attempt to use NAA to characterize potential clay sources in the region. On the basis of this study, we argue that the majority of domestic ceramics from Caleta Vitor share compositional similarities with clay samples collected from nearby valleys, allowing us to infer that the Caleta Vitor populations primarily procured their clay for domestic ceramics from local sources throughout a 1500‐year period. Thus, despite the fact that there were inter‐regional interactions during this period that included the influence of powerful Andean polities, it would appear that domestic ceramics continued to be produced locally, and by implication it can be argued that such interactions did not substantially affect this sphere of material culture production. Further, the apparent continuities in domestic ceramic production allow us to reflect on local decision‐making processes throughout the cultural phases considered in this research.  相似文献

This article investigates how concepts from the field of public policy, in particular the Advocacy Coalition Framework (ACF) initially introduced by Sabatier and Jenkins‐Smith, can be applied to the study of foreign policy analysis. Using a most similar comparative case studies design, we examine Switzerland's foreign policy toward South Africa under apartheid for the period from 1968 to 1994 and compare it with the Swiss position toward Iraq after the Iraqi invasion of Kuwait in 1990, when the Swiss government imposed—for the first time—comprehensive economic sanctions against another state. The application of the ACF shows that a dominant advocacy coalition in Swiss foreign policy toward South Africa prevented a major policy change in Swiss–South African relations despite external pressure from the international and national political levels. Actually, quite the opposite could be observed: Swiss foreign policy increased its persistence in not taking economic sanctions against the racist regime in South Africa during the 1980s and early 1990s. The ACF, with its analytical focus on policy subsystems and the role of external shocks as potential triggers for change, provided a useful framework for analyzing the factors for policy change and stasis in Swiss foreign relations toward the selected two countries.  相似文献

The history of melancholy depression is rich with images of movement retardation and mental dysfunction. The recent restoration of psychomotor symptoms to the diagnostic terminology of affective disorder is not novel to the students of medieval melancholia. The move back to the biology of this psychomotor dysfunction with the technical advances in brain imaging in recent years only echoes centuries-old writings on the centrality of movement changes in the depressive condition. The Inferno, the first cantica of Dante Alighieri's Commedia, has a wonderful abundance of allusions to the importance of psychomotor symptoms in describing the depressed individual. Slowed steps, garbled speech, frozen tears, these and many other images keep the physical manifestations of psychomotor suffering in the forefront of the reader's mind. Considering Medieval and Renaissance writings on melancholy suffering, it is fitting that Dante shows a bodily illness reflected in the hellish torments visited on the damned. From the souls of the sullen to those of the violent, the panorama of psychomotor symptoms plays a prominent role in the poem as well as in the medical and literary prose of succeeding centuries.  相似文献

This article examines miscegenation fears in Britain in the period after World War I, noting three dominant discourses: that miscegenation leads inevitably to violence between white and black men (focusing on the 1919 race riots), that these relationships involve sexual immorality (analysing the 1920 ‘Black Horror on the Rhine’, a case involving a white woman, a Chinese man and drugs and a trial of a white woman for killing her Egyptian husband) and that miscegenation has ‘disastrous’ procreative consequences. It is suggested that miscegenation stood as one British boundary marker, separating the nationally acceptable and the nationally threatening. The parties concerned – the ‘primitive’ man of colour, the white woman of a ‘low type’ and the ‘misfit’ offspring – were each pathologised in terms of their deviant sexuality. Yet interracial relationships did not decrease, quite the contrary. The move in Britain towards a more racially mixed community began in the years after the Great War, when certain white women made choices against the norms of respectable femininity.  相似文献

We examine evidence for Holocene contact between Asia and North America across what is now the Bering Strait, emphasizing maritime adaptation. After 10,000 B.P. residual influence of the Siberian Paleolithic is clear, and derivative Americans were moving southward along the open Pacific coast and settling in the eastern Aleutian Islands. By 6000 B.P. maritime adaptation is evident in the Kodiak Island region, and expansion westward brought colonization of the entire Aleutian chain of islands before 3000 B.P. In Asia there was marine subsistence on Hokkaido by 6000 B.P, but in the lower Amur River region, the southern and northern regions of the Okhotsk Sea, the coast of Kamchatka, and the Chukchi Peninsula no major maritime interest can be dated until after 2700 or even 2500 B.P In north Alaska, the mainland was cut off from Siberia by 6000 B.P with the rise of postglacial seas, but contact was reestablished 5000 B.P at the cultural level of the nonmaritime Siberian Neolithic. Pronounced marine orientation appears intrusively in north Alaska somewhat before 3000 B.P, when the only known source for the technology was the region extending from the Gulf of Alaska through the Aleutian Islands. Thereafter developed the maritime culture of the historic Eskimo people.  相似文献
