The article explores the role of state-owned enterprises (SOEs) in the globalisation of China's infrastructure capital. Examining how accumulation strategies of Chinese SOEs are driven by a complex set of political and economic, state and private, interests, it foregrounds the inherently hybrid nature of China's state capitalism. We use Kenya's Standard Gauge Railway (SGR) as a case study to analyse how state infrastructure capital traverses borders, and the specific ways that contradictions of accumulation in China are relocated through the improvised hybridity of SOEs. In Kenya, China Road and Bridge Corporation, the main SGR contractor, shifted and adapted its strategies as the pursuit of economic productivity gave way to political priorities in China, simultaneously responding to changing socio-political circumstances in Kenya and across East Africa. Analysing these dynamics, we highlight the contingencies of, and limitations to, structural reorganisation of actually existing forms of state capitalism in China and beyond.  相似文献

Near Eastern fieldwork in mining archaeology and archaeometallurgy began at Timna (Israel) in the 1960s and 1970s and continued in Feinan (Jordan) in the 1980s and 1990s. For the first time, Bronze Age copper mines were excavated and cleared and importance was given to the slag recovered. At both sites copper was produced for over 5000 years, from the Chalcolithic to the Mamluk periods. Although the broad outlines of technical development can be traced, much remains to be learned in future studies.  相似文献

In May 2003 the author observed a clench-fastened boat near Chertala, Kerala, India. The boat appears to indicate a vessel-type previously undocumented in the area. This article reports the observations made of the vessel and its pertinence to the boat-construction traditions of Kerala and the subcontinent.

Abstract

The results of an analysis on plant remains (fruit, seeds, pollen and wood) found in sediments in a Roman well in Vada Sabatia (Vado Ligure, Liguria, Italy), dated between the first and fourth centuries AD are presented. The remains are well preserved and constitute an exceptional record of the Ligurian area. Five layers have been recognised: three corresponding to the well when in use and two to the well when it was no longer in use. The vegetational cover of the area has been found to be similar to that observed in the coastal plain near Albingaunum (Albenga) pertaining to the same period. Moreover, the two superficial layers have cumulated a large amount of macroremains related to the period in which the well was no longer in use. The principal tree and vegetable crops and cereals of the coastal plain were present, due to the influence of maritime and mercantile trade, as were the prevailing ruderal and weed species and the tree cover. The presence of carpological remains of Castanea sativa, Secale cereale, Beta vulgaris and Cucumis sativus is reported for the first time in the Roman Age in Liguria. The influence of the arrival of the Romans can be seen from new crops, such as Prunus persica, and the introduction of exotic fruit like Phoenix dactylifera and Ziziphus jujuba. Several wooden artefacts, for example, a rack for drying lucerne and a tool handle, made of Cornus or Viburnum and Viburnum cf. lantana respectively, have been found. The well has proved to be an ideal location for the preservation of plant remains compared with other studied archaeological situations in Liguria and in Southern France, as it presents a higher variety of cultivated fruits, vegetables and cereals.  相似文献

This paper shows that many food remains excavated from Herculaneum were microbiologically contaminated, and that the Romans probably had continuous exposure to gastrointestinal diseases. However, palaeopathological analysis of skeletal remains from Herculaneum shows a low prevalence of non‐specific bone inflammation. Pomegranates and figs, consumed by the population, were mainly dried and invariably contaminated by Streptomyces, a bacterium that produces natural tetracycline, an antibiotic. Histological analysis of the human remains demonstrates fluorescence typical of this substance. The tetracycline‐labelled human remains show that the Roman inhabitants of Herculaneum ate food contaminated by Streptomyces, and this may explain the rarity of inflammatory bone diseases at the site due to non‐specific infection in the living population. This interpretation fits with therapeutic indications suggested by Roman physicians that preserved fruits were used to cure some inflammatory diseases.

The turbulent climate of the Great Plains made windbreaks necessary for the protection of settlers and their livestock and crops. At first individual farmers tried to plant their own shelterbelts but with little success. The US Forest Service, with the establishment of the Bessey tree nursery, in 1902, and the field planting of the Nebraska National Forest, developed the expertise to carry out farm forestry on the plains. In 1934 the Forest Service undertook the Prairie States Forestry Project, an eight‐year program to plant shelterbelts from Canada to Texas, in response to the Dust Bowl and the Great Depression. These shelterbelts were a technological solution to environmental and social problems. As they grew, successful shelterbelts developed forest characteristics and served as habitat for birds and wildlife. As systems that were both technical and ecological, shelterbelts embodied a confluence of culture and nature in the technology that farmers and foresters used to engineer a more suitable environment for American society on the Plains.  相似文献

From the late 1600s to the early 1800s, Irish migrants journeyed to Newfoundland to take advantage of opportunities in the lucrative Newfoundland cod fishery. Focusing on the eighteenth and nineteenth centuries, this essay explores constructions of Irish-Newfoundland womanhood as articulated by local British officials, the Catholic Church, and male-centred family history narratives. These discourses located women at the margins of early settlement experiences or rendered them invisible altogether. Yet Irish-Newfoundland women were able to negotiate their own subjectivities within this discursive terrain, finding spaces for identity construction in the disjuncture between rhetoric and lived experiences. Some resided more immediately under the hegemonic gaze and struggled to break free from dominant narratives. But most became essential workers in household fishing production outside the capital of St John's, and their vital contribution as shore crews gave them considerable power and authority both in their households and in the broader community. Performing demanding physical work on stages and flakes (elevated wooden structures) or in gardens and fields, carrying out various economic activities in their own right, they were hardly the unproductive, unruly bodies of British official discourse or the passive flowers of civilisation narrated from Catholic pulpits. And far from being absent from the migration story, they were central players in community formation and the economic life of the island. In this historical context, proximity to/distance from hegemonic knowledge production created variations in identity construction within a group often represented in the literature as homogeneous and powerless.  相似文献

This paper examines performances of hospitality in everyday life to explore the lived experience of “being Moldovan”. National identity in Moldova can only be understood by reference to the peculiarities of history—to the presence of a neighbouring kin-state (Romania), a multiethnic population, Soviet ideology, and successive efforts at nation-building. The instabilities, contradictions, and ambiguities of national identity are also experienced and interpreted, as they are regularly performed in informal and formal settings. The “hospitality” of Moldovans—performed daily through linguistic code-switching, in practices of buying and selling, in life-cycle celebrations such as weddings, and in the official greeting and welcoming of dignitaries and visiting delegations by folk-costumed performers—is, paradoxically, an important site of this experience of ambiguity. The same set of practices both renders its performers “masters of their own houses”, while at the same time revealing the limits of the metaphor.  相似文献
