秦汉时期,木炭作为主要燃料之一,被广泛使用于民众生活以及手工业生产领域如冶金、制陶、煮盐等诸多方面。规模巨大的木炭用度,造成了林木资源的过度破坏,进而引发了严重的生态效应。两汉社会生态恶化以及自然灾害频发,与此有密切关联。  相似文献

Organic food consumption is one of several new trends in eating read as active opposition to industrialized food provision. While fast food consumption is characterized by compulsive gluttony, manifest in fat bodies, alternative consumption practices are seen to be driven by conscious reflexivity, such that consumers monitor, reflect upon and adapt their personal conduct in light of its perceived consequences. The purpose of this paper is two-fold. One is to examine the evolution of organic food from what Belasco called the 'counter-cuisine' to what organic growers call 'yuppie chow', to show how organic salad mix was the carrier of major changes in the organic system of provision, thereby calling into question the notion that organic food is necessarily an antidote to industrialized food. The other is to problematize the facile dichotomies between fast and slow, reflexive and compulsive, fat and thin, and, hence, good and bad eaters, to show where there is slippage and instability in these categories, in addition to a troubling politics of class and gender. To these ends, I showcase the changing provision of a particular organic commodity (salad mix, or mesclun) in California.  相似文献

An American specialist on Russia's agricultural sector examines the progression and impact of that country's 2010 drought (the worst in a half-century), leading to a grain harvest one-third smaller than originally forecast. A particular focus is on the country's grain reserves and the government's response to drought in such areas as grain export policy and maintaining the size of the domestic livestock herd, responses which the author argues are conditioned by the drive for food security, a concept that has dominated the political discourse in tandem with resurgent economic nationalism during the post-Soviet period.  相似文献

Quantitative calculations on the use of natural resources provide valuable tools, which can give new insights to old questions and rise new ones. In this article, I compare the wood consumption in the production of potash, saltpeter and pine wood tar in 19th century Finland. My calculations shows that in the 19th century the cumulative wood consumption in the production of potash might have been higher or at least on the same level as in the production of tar, while the production of saltpeter consumed only a fraction. In the 1830s their combined wood consumption reached the level of slash‐and‐burn cultivation.  相似文献

This article examines the lives of academic women in Mérida, the state capital of the Yucatán in southern Mexico. In particular, I consider the relationship between work – including household management – and consumer practices in light of Mérida's changing socioeconomic climate. I address how women's lives have been impacted by the neoliberal restructuring of Mexico's political economy and what these changes mean to their experience of university life, household management styles and consumption practices. I point out how labor and consumption are deeply interrelated cultural practices, which have acquired new meanings in the neoliberal landscape. Accordingly, consumption practices must be understood in connection with women's social and professional identities.  相似文献

The degradation of archaeological wood at freezing and thawing temperatures is studied at the site of Qajaa in West Greenland through a combination of environmental monitoring, measurement of oxygen consumption and microscopy of wood samples. Permanently frozen wood is still very well preserved after 2–4000 years, while wood samples that thaw every summer show attack by soft rot and an average density loss of 0.1 g cm–3 (corresponding to 25% of the dry mass) over the past 27 years. Future increases in temperature may increase the decay rate significantly (Q10 = 4.2 at 0–10°C) but the effects on site depend on local hydrology.  相似文献

‘Leisure shopping’ is a particular kind of shopping activity that is devoted mainly to fashion clothes and accessories. Women are commonly represented as the main leisure shoppers, and consequently, they tend to be at the centre of shopping centres' mainstream discourses. This article argues that interpretations of representations of ‘leisure shopping’ and the corresponding practice have too often ignored the daily and seemingly ‘banal’ experiences of the social actors involved. The primary purpose of this article is to show how gender roles are performed and reified in high-end factory outlet villages in Italy. It adopts a cross-sectional approach to ‘leisure shopping’ that includes an analysis of the ‘languages’ of two Italian high-end factory outlet villages, the ‘social space’ represented by the same sites and the ‘stories’ about a few ideal-typical female shopping experiences. These aspects are situated in the Italian cultural and political context at the time the research was conducted. Very different demands – such as sensuality, efficiency and motherly care – are put on women in Italy, as well as in the majority of Western societies. The analysis reveals that through their practice of browsing in a high-end factory outlet village, women often reproduce stereotypes while simultaneously trying – though ambiguously – to challenge them.  相似文献

We propose the existence of extensive trade and interaction among the peoples of the American Southwest and Mesoamerica. We base this inference on our detection of the widespread presence of theobromine, the biomarker for cacao, in 50 of 75 vessels used by Ancestral Puebloans (previously referred to as Anasazi) elites and non-elites from the Four Corners area and Hohokam elites of the Gila and Salt river valleys in the prehistoric American Southwest. We used a non-invasive, non-destructive aqueous sampling procedure that provides conservation advantages over the current methods that require crushing and boiling sherds or removing residues from vessel surfaces. Analysis of these samples by sensitive LC-MS instrumentation capable of detecting nanogram quantities of material revealed theobromine in non-local vessel forms found in elite burials in great house and platform mound sites as well as in local vessel forms used by non-elites living in small unit-pueblos. After elimination of plants native to the Southwest as the source of theobromine, we conclude that either Theobroma cacao or Theobroma Bicolor was imported from its homeland in the Mesoamerican tropical coastal lowlands. Our results are at odds with the current consensus that there was little systematic commerce between Mesoamerican and Southwestern polities. We suggest that cacao was exchanged for high quality turquoise such as that mined in the Cerrillos, New Mexico mining district. We conclude that, far from being isolated developmentally, this trade integrally tied populations in the American Southwest to the socio-political and economic activities of Mesoamerican states.  相似文献

Singapore, a leading country in the Asia‐Pacific region, is currently attempting to transform its cultural industry into creative economy. Creative economies capitalise on how knowledge can be marketed by merging arts, technology and business. They ensure a nation's competitiveness within an integrated global economy. This paper critically examines Singapore's recent cultural policy developments in tourism, broadcasting and new media. It argues that new creative industries have produced new consumption patterns and identities that harness the place‐branding of “New Asia” as a form of cultural capital and a strategy of regional dominance. Cybernetics is proposed as an approach to frame creative cultural governance and consumption in Singapore.  相似文献
