The present work aims to analyse the magnetic signature from the Late Holocene open‐air archaeological deposits of hunter–gatherer ephemeral occupations. For this purpose, two profiles were sampled at the Marazzi 2 site in the north‐western Isla Grande de Tierra del Fuego, Chile, in order to carry out studies of magnetic susceptibility, hysteresis cycles, back‐field remanent magnetization, isothermal remanent magnetization and thermal variation of magnetic susceptibility at high and low temperature. Despite short‐term occupations, the P1 profile shows a magnetic peak at a depth of ~30–70 cm due to magnetite, probably formed by anthropogenic activity related to combustion. The P2 profile instead yields an anomalous peak of coercivity (at a depth of 20–40 cm), which could also be anthropogenic, due to the presence of finely dispersed ancient ‘red ochre’. The red ochre is proposed to form anthropogenic thermal alteration of goethite associated with volcanic ash, the remnants of which were found in thin sections from the P2 subsoil. 相似文献
Two schools have dominated environmental justice literature: the race school and the class school. The class school tends to explain cases of environmental injustice exclusively from the vantage point of socioeconomic differences. The race school, however, foregrounds racism as an explanatory framework, while still acknowledging the relative role of class in this regard. Both schools tend to base their analyses primarily upon research findings from empirical/geographical studies. This paper joins its voice with the recently growing body of literature that has started to call for the need to transcend this cumbersome race–class dichotomy and move beyond the mundane pattern of case studies research and statistical data gathering. Specifically, it propounds a theory of spa‐cial formation that illuminates the parallel processes of spatial discrimination and racial subjugation, stresses the historical contingency of environmental racism, and highlights the role of the various cultural images, representations and meanings attached to black geographies in laying the moral and ideational foundations facilitating the process of spatial and environmental discrimination against African Americans. 相似文献
In the study of the Classic Maya collapse around the 9th century a.d., scholars tend to emphasize its gradual nature. New data, however, point to multiple episodes of rapid social change that affected wide areas. We investigated these critical moments at Ceibal (Seibal), Guatemala, through intensive excavations in its Group D. This naturally defensible location was used as a primary elite complex, possibly including a royal palace, during the Late Classic period (a.d. 600–810). By refining the chronology, we have identified four episodes of political disruption, including the impact of a military defeat by the Dos Pilas dynasty in a.d. 735, the takeover of Ceibal by an illegitimate ruler in a.d. 771, the ritual destruction of various buildings at the Ceibal dynastic collapse around a.d. 810, and the final abandonment of Ceibal around a.d. 900. These finds provide significant insights into the process of political disintegration in the Maya lowlands. 相似文献
This article uses a new data-set to calculate the ‘political economy’ or nature and purpose of taxation and spending in Jamaica between 1768 and 1839. It argues that these levels increased considerably, both in absolute terms and relative to the size of the population and economy of the island, and that the assembly raised taxes mainly to protect the white elite and the plantation economy against slave revolts and foreign invasion. Although the balance of spending shifted after Emancipation in 1834, the purpose did not, since military spending was simply redirected to subsidise policing and the cost of public order. Depending on how the national income or gross domestic product of the island is calculated, levels of taxation rose from 2 per cent in peacetime to about 4–6 per cent in wartime, peaking at 6–8 per cent in moments of crisis. White elites therefore made a significant contribution to the cost of their own defence, and to the wider projection of imperial power, and were willing to tolerate increasingly high levels of taxation because it was spent in ways that suited their interests. They thereby formed the colonial sinews of imperial power. 相似文献

A new grylloblattid (Permoshurabia argentina sp. nov.: Geinitziidae) is described and illustrated from the Upper Triassic of Argentina. The material represents the first record of this family from Argentina and expands the geographic distribution of this group during the Triassic.

Historians have recently turned their attention to the place of masculinity in the politics of early-modern England. This essay widens that exploration to include the imperial settings of Ireland and North America. Drawing upon a range of English- and Irish-language sources – including political treatises, maps, state papers and court poetry – it contends that manhood, as a relational value between men, helped structure the form and character of politics in the metropole, the kingdom of Ireland and the American colonies. In all of those settings, the definition of acceptable male behaviour was different, the effect being that political action and theory in each place took on unique features. Consequently, the essay cautions against studying England and its colonies as distinct units of historical analysis and calls for further exploration of the particularities of colonial settings and their influence on the imperial centre. Moreover, the essay aims to demonstrate that masculinity, particularly contest over its proper expression, is an agent in historical change, in this case helping to shape political theory and practice as England developed into a multiple monarchy and budding imperial power in the sixteenth and early seventeenth centuries. 相似文献
Little research examines the stage of the policy process during which policy alternatives are formulated. Using quantitative and qualitative data from Swedish local politics, we address this deficiency by analyzing the process by which the number of specific policy alternatives is reduced. The findings suggest that, in approximately 20 percent of issues, more than one alternative will reach all politicians making the binding decisions. Most local politicians, in both the majority and opposition factions, think that they lack sufficient information on alternative policy designs. We also find a “political bias,” that is, alternatives are discarded at an early stage because they are deemed not politically feasible. Politicians outside the inner circles, especially those with higher education, would like to see more policy alternatives to discuss and from which they can make choices. 相似文献
This paper investigates the spatial organization of social relations in settlement contexts through a quantitative and distributional analysis of surface ceramic attributes from Iron Age Period (1200–300 BC) archaeological sites in Southern India. The results discern variation in depositional contexts across each site, from which I infer a variety of basic settlement activity structures (e.g., site maintenance, trash disposal, residence, animal husbandry, metallurgy, ritual). I use these results, together with further analyses of artifact and feature distributions, to infer a basic suite of places, place-making practices and some of the social relations and organizational structures that produced these historically unique Iron Age settlement landscapes. 相似文献
