内蒙古中南部考古学文化演变的环境学透视   总被引:2,自引:0,他引:2  
魏峻 《华夏考古》2005,(1):62-68
内蒙古中南部位于我国北方农牧交错带的中段, 是气侯变化的敏感地区。全新世以来的气侯波动, 对于塑造这里的自然景观和古文化的面貌起着重要的作用。本文分析了全新世大暖期的不同时段上古文化的特点和生计方式的变化, 并从沙地进退、湖面升降的视角探讨了这一地区考古学文化的演变以及人地之间相互作用的过程。  相似文献

This essay explores the post-World War Two anti-colonial Maasina Rule in north Malaita, Solomon Islands, to show how a church leader Shem Irofa'alu decided to establish a religious movement independent of the state and the traditional evangelical church. Irofa'alu's movement indexes an important moment of culture change towards increasing enthusiasm for the often-overlooked Christianity-based forms of sovereignty in the region. It highlights that Maasina Rule was not only a powerful rupture in social processes, but also sharpened the growing division between state and church. Irofa'alu's role in Maasina Rule shows that his influence peaked between 1948 and 1950 and then went into rapid decline. This change in fortune coincided with a critical turning point in the colonial government's attempts to end the movement through appeasement. No longer the head of the evangelical church in Malu'u sub-district and frustrated about the mother church's governance, Irofa'alu retreated to his home area and set about establishing a new church, Boboa (‘Foundation’), his first attempt at organizing a self-governing assembly before introducing Jehovah's Witnesses in north Malaita. In later years, Irofa'alu became a prophet-exemplar for new generations of religious leaders trying to establish Malaitan sovereignties based on their own power to move the truth of prophecies away from foreign state and church organizations.  相似文献

The agronomic writings of influential theorist and independence leader Amílcar Cabral contain a hitherto underappreciated dialectical approach that is environmental, nonreductive, spatialised, nonteleological, and anticolonial, with significance for geographies that are simultaneously critical, physical, Southern, Black, African, and decolonial. Cabral's interests in socionatures—and especially colonialism and the state—emerged from childhood in colonial Cabo Verde. His undergraduate thesis examines dialectics of soil erosion and agrarian structures in Portugal, amidst his politicisation and anti-colonial networking. He developed his dialectical approach spatially as he conducted Guinea-Bissau's agricultural census and advanced beyond methodological nationalism and evolutionary stagism by emphasising colonial connections (colonial state mechanisation and export crops in African agrarian systems). These insights and concerns shaped and were shaped by his work on warehouses, Angolan plantations, and broader post-1960 liberation struggles to suggest that a rural guerrilla strategy was possible and necessary in Guinea through dialectical engagements with diverse peasantries and international support.  相似文献

To what extent do mining environmental assessments in British Columbia (BC) consider gendered impacts? How are they considered? And how are these considerations shaped during the environmental assessment process? To answer these questions we undertook a systematic review of all completed BC mining environmental assessments between 1995 and 2019 (n = 37). Through a careful reading of documentation archived in the BC Environmental Assessment Office registry, we found that 60% of projects did not consider the gendered impacts of mining development; the remaining 40% of projects inconsistently assessed gendered impacts. While noting an increase in gender considerations in environmental assessments since 1995, also quantified in our results is what has not changed. Even where gender is considered, the assessments often collapse this concern into one of “women's issues,” obscuring intersectional impacts and downplaying violence along racialized and gender diverse lines, including those experienced by Indigenous women, children, two-spirit, trans, queer and non-binary people. Environmental assessment is a regulatory tool designed to adjudicate the impacts of mining projects, yet our results lead us to conclude that it is also a tool of environmental injustice, compounding and further sedimenting heteropatriarchal and racialized patterns produced through generations of settler colonial resource extraction in BC.  相似文献

James Arthur Prescott was a prominent soil scientist whose career responded to an increasingly complex, recognisably Australian web of interpenetrating spatial scales, served to promote revolutionary global advances in his chosen field, and in the process negotiated the blurred boundaries between ‘pure’ and ‘applied’ research. Encounters with this instructive life suggest that, while resolutions of pivotal anxieties might turn on ineluctably personal qualities, they also reflect a dynamic interplay between international, imperial, national and state contexts. Prescott's innovative contributions to soil science, fruits of a tenaciously consolidated career, influenced resource appraisal and environmental management across a prodigious continental expanse. A sustained focus on local and regional development brought him into contact with a wide range of contemporaries, including pioneering geographers, and culminated in his election to a Fellowship of the Royal Society.  相似文献

This article first examines the Truth and Reconciliation Commission’s recommendation of symbolic reparation for apartheid, and its effect on South African heritage. Second, it considers the relationship between public history and civic nation building in South Africa, as well as problems in trying to develop an inclusive public history through museums. Case studies drawn from Grahamstown and Mthatha in the Eastern Cape are explored as examples of the redevelopment of the old and establishment of the new public history as part of the negotiated transition.  相似文献

The two Mw 6.5 earthquakes on June 17 and 21, 2000, respectively, in the populated South Iceland Seismic Zone (SISZ) significantly augmented the Icelandic database of strong ground motions, and several strong velocity pulses were recorded at near-fault sites. The strong motions are interpreted via the Specific Barrier Model (SBM) and a mathematical model of near-fault velocity pulses. The data indicates self-similar source scaling and significantly greater attenuation of seismic waves than in other interplate regions. Through inversion of the data a new attenuation function for the SISZ has been adopted, which results in unbiased simulations. For the first time, the characteristics of the recorded near-fault pulses have been identified and compared to the worldwide database of such records. The SBM and the near-fault pulse model combine naturally in a fast and efficient synthesis of realistic, broad-band strong ground motions in the far-fault and near-fault region. Such simulations are showcased for the June 2000 earthquakes and indicate that the modeling approach adopted in this study is an effective tool for the estimation of realistic earthquake ground motions in the SISZ.  相似文献

Despite the political and social transformation set in motion by the collapse of apartheid and the advent of democracy in 1994, South Africa's migration policy remained mired in the past. The Aliens Control Act of 1991 continued to govern the country's policy until the passage of the Immigration Act of 2002. After amendment in 2004, the Act finally came into force in July 2005. This paper focuses on the implications for South Africa and the SADC region of persisting with a policy framework devised in the apartheid period. First, the mine migrant labour system has remained intact despite a prolonged economic crisis in the mining industry. Second, the national introspection of the first democratic government led to a major decline in legal migration and immigration to South Africa. Third, apartheid‐era tactics of migration enforcement intensified through a process of ‘violent othering’. Fourth, the old framework was sexist as well as racist, and while the new policy is gender neutral in language, it is not gender equal in effect. Finally, for a decade, South Africa successfully resisted SADC attempts to develop a regionally harmonised approach to cross‐border migration. Recent changes in South African Government policy, particularly the new JIPSA initiative, suggest that the ‘lost decade’ may finally be over. However, without major policy transformation, the unseemly history of post‐apartheid migration policy will continue.  相似文献
