Accumulation by dispossession and hazardscape production in post-corporate gold mining in Itogon,Philippines

This study investigates the experience of a gold mining community two decades after corporate mining activities ceased and were replaced by informal subcontract small-scale mining in Itogon, Philippines. Drawing on David Harvey’s accumulation by dispossession and Daanish Mustafa’s hazardscape, we consider the lasting effects, from 1903, of dispossession upon the establishment of the first commercial mines in the Philippines as experienced by traditional miners in Itogon. Despite the closure of mining operations, mineral lands remain privately owned, resulting in the persistence of legal land dispossession among local small-scale gold miners. Mining activities still continue as small-scale miners are able to access abandoned mines through subcontract mining. Subcontract mining has changed the source of capital that funds mining activities from mining corporation to rent-seeking small-scale mining financiers, but the new economic relations still benefit from the capitalist logic of low natural resources and labour value. We argue that the production of hazardscapes is a consequence of accumulation by dispossession through (1) processes of expropriation of mineral lands and the consequent creation of free labour among local miners; (2) the externalisation environmental cost as an accumulation strategy that results in the production of socionatural hazards; and (3) exploitation of those who labour and who are made to work in precarious work environment while contributing to the production of hazardscapes.     

The Santa María pottery of El Bolsón valley (Catamarca,Argentina): Compositional characterization and implications on the elaboration processes,ca. 1000–1600 ce

The results obtained from the multi-analytic compositional characterization of ceramic pastes and paints of the Santa María style, from the El Bolsón valley (Belén Department, Catamarca Province, Argentina), are presented here. This pottery style had a wide regional distribution in Northwestern Argentina between ca. 1000 and1600 ce and is characterized by its complex iconography painted in black, cream and red. The analyses show that the containers correspond to the technical tradition of using grog temper and suggest that its manufacture involved a double firing process. This reveals a new practice for the time.     

Inconsistent,downplayed, and pathologized: How mining's gendered impacts are considered in BC environmental assessment

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.     

Extraction and the Ocean “Frontier”: Dispossession,Exclusion, and Resistance in Namibia

The perceived neglect of the ocean to state and industry actors has seen frontier rhetoric emerge as it is rendered visible under the Blue Economy agenda. By framing the marine scape as underutilised, capitalist expansion is being legitimised. Drawing on the case of Namibia, I argue that the afterlives of colonialism and apartheid are being repurposed to present the ocean as a Blue Economy opportunity. The physical disconnection of citizens from the marine scape, and the dominance of fishing and mining industries, has been used by state and development actors to present it as empty of socio-cultural relations. However, to declare Namibia’s coasts and ocean as forgotten unless articulated through capital is to conceal that they have been labelled “no-go” zones. I argue that, by considering exclusions and looking beyond proximity in discussions of equity and representation, the marine scape is articulated by civil society, to elucidate forms of resistance.     

汉代复色低温铅釉陶器初探

复色釉陶是汉代低温铅釉陶中的一个特殊品种,其施釉烧制工艺系在普通单色釉陶的基础上,于一件器物上施加两种及以上釉料,以低温一次入窑烧制而成,呈现出绚丽的艺术效果,达到了汉代釉陶的高峰。此类釉陶主要分布于宝鸡、济源和延安及其周边地区;最早出现于西汉中晚期,流行于西汉晚期至东汉初期。就施釉工艺而言,其多色施釉技术与北魏时期的二色釉陶一脉相承,并在北齐时期与新出现的"瓷胎铅釉陶"二次烧制技术相结合,形成了北齐特有的多色瓷胎铅釉陶器,为后来唐三彩的出现奠定了技术基础。

明初大运河南旺分水枢纽水工技术考

明朝初年,国脉皆仰东南,为解决南方粮财物的北运问题,宋礼和白英受命组织修建了大运河山东段南旺分水枢纽。该枢纽主要包括引汶济运、导泉补源、设立水柜和置闸节流四个组成部分。其中,引汶济运是工程之重点,包括戴村坝、小汶河、南旺分水以及配套工程等四个子系统。这些水利设施组成一个和谐的系统工程,保证了该段运河的水量稳定充足,从而实现了大运河500余年的正常通行。南旺分水枢纽代表了我国古代运河水工的最高科学技术成就,堪称世界水利史上的一大经典范例。     

A technological study of ancient faience from Egypt

The chemical compositions and microstructures of some 35 faience objects from Egypt spanning the period from the Middle Kingdom through to the 22nd dynasty are determined using analytical scanning electron microscopy. Replicate faience beads glazed in the laboratory using the efflorescence and cementation methods are similarly investigated. In efflorescence glazing, there appears to be preferential efflorescence of soda over potash, and in cementation glazing, preferential take up of potash over soda into the glaze. These data are then used to try to infer the raw materials and methods of glazing employed in the production of the ancient faience. The glaze/glass phases present in the faience differ significantly in composition from that of New Kingdom glass. This could be due either to the use of different plant ashes or to changes in the composition of the plant ashes during the production of faience and/or glass. Although it is only rarely possible to determine with certainty whether ancient faience was glazed by efflorescence, cementation or application, the observed microstructures provide an indication of the approach adopted to achieve desired performance characteristics such as strength.     

乾隆初年政府职能扩展的几个例证

世界历史在18世纪出现了罕见的“共时现象”,其中最明显的就是政府职能的扩展。但在中国,相比之下这段历史却不太为人注意。本文力图展示乾隆初年清代政府在劝农、兴修水利和开矿几个方面的所作所为。如果说,在18 世纪的西欧,政府职能扩展已属于一种“现代现象”,那么我们又应如何看待中国的这段历史?
