This article analyses the inter-relationships among food consumption practices, marketers' representations of sugar, and the history and political economy of sugar production. It focuses on the 'supermarket narratives'--stories regarding place and production that appear on commodity packaging--used to market sugar in the USA. It explores how competition within the sweetener industry, as shaped by the material qualities of sweeteners, has given rise to supermarket narratives that seek to differentiate sugars on the basis of ideas of place, freshness and environmental sustainability. It also examines how, at the same time, sweetener users have co-operated to maintain and increase consumption in the USA. The article begins with a discussion of historical patterns of sweetener consumption in the USA, and then looks at the genesis of the primary sugar industry lobbying organization. The case study of Florida sugar producers is used to demonstrate the historical antecedents of supermarket narratives and the contemporary geographical specificity of the political economy underlying supermarket narratives.  相似文献

The butter clam, Saxidomus gigantea, is one of the most commonly recovered bivalves from archaeological shell middens on the Pacific Coast of North America. This study presents the results of the sclerochronology of modern specimens of S. gigantea, collected monthly from Pender Island (British Columbia), and additional modern specimens from the Dundas Islands (BC) and Mink and Little Takli Islands (Alaska). The methods presented can be used as a template to interpret local environmental conditions and increase the precision of seasonality estimates in shellfish using sclerochronology and oxygen isotope analysis. This method can also identify, with a high degree of accuracy, the date of shell collection to the nearest fortnightly cycle, the time of day the shell was collected and the approximate tidal elevation (i.e., approx. water depth and distance from the shoreline) from which the shell was collected.Life-history traits of S. gigantea were analyzed to understand the timing of growth line formation, the duration of the growing season, the growth rate, and the reliability of annual increments. We also examine the influence of the tidal regime and freshwater mixing in estuarine locations and how these variables can affect both incremental structures and oxygen isotope values. The results of the sclerochronological analysis show that there is a latitudinal trend in shell growth that needs to be considered when using shells for seasonality studies.Oxygen isotope analysis reveals clear annual cycles with the most positive values corresponding to the annual winter growth lines, and the most negative values corresponding to high temperatures during the summer. Intra-annual increment widths demonstrate clear seasonal oscillations with broadest increments in summer and very narrow increments or no growth during the winter months. This study provides new insights into the biology, geochemistry and seasonal growth of S. gigantea, which are crucial for paleoclimate reconstructions and interpreting seasonality patterns of past human collection.  相似文献

This article considers the role of visualising in the formation of the nation narrative. It foregrounds the significance of gender performance in early twentieth-century Irish cultural nationalism. Prior to the consolidation of a hegemonic narrative of state, spaces existed for the exploration of a range of possible projections of identity. This study focuses on one of those possibilities, namely a series of costume photographs where gender is literally performed. A contextual reading of these photographs is offered in order to situate them within the formation of the nation narrative. The gender of the nation is enacted through performativity, which through its repetition comes to be seen as natural. The photographs under consideration here undermine that process of naturalisation by revealing a more complex and contradictory history of the relationship between gender and nation. The omission of this more complex representation in the Irish narrative, it is argued, reveals how monopoly of narrative is integral to both hegemonic control in the visual field and how we understand the nation.  相似文献

Material remains of harness elements from different parts of the Roman Empire have contributed to a new interpretation of the harness depicted on funerary reliefs of the second‐third centuries AD from north‐western Europe and on other figured documents, such as Trajan's Column in Rome (dedicated in 113 AD). As recent experimental reconstruction has shown, the curved wooden plaques, held firmly in place by a metal bow, may have formed a precedent for the collar and hames developed during the Middle Ages into the form still in use today. The most important innovation was the introduction – no later than the second century AD – of single draught between shafts, replacing traditional paired draught with pole and yoke. There is even some evidence that other elements of modern harness, such as traces and the whippletree, hitherto considered to be medieval inventions, were also known during the period of the Roman Empire.  相似文献

Abstract

Aotearoa New Zealand is a nation of promise, potential and enigma: it was the first country in the world where women gained the vote in 1893 and now boasts the youngest woman world leader in 2017. It is also a postcolonial nation where structural racism, homophobia, and sexism persist, yet it has also given legal personhood to a river. Our Country Report foregrounds Aotearoa New Zealand feminist geographic scholarship that responds to, reflects, and sometimes resists such contrasts and contradictions at the national scale. We employ the lens of the 2017 national election to critically engage with current gendered and indigenous politics in the country. Analyzing these politics through three ‘feminist moments,’ our paper highlights the breadth and scope of current Aotearoa New Zealand feminist geographic scholarship and directions.  相似文献
