After the Second World War, the wool textile industry faced a significant labour shortage as its traditional workers escaped the poor wages and conditions of wool mills for better-paying, cleaner jobs. Three broad solutions to this crisis were adopted: the employment of immigrants, mainly from the Indian Subcontinent and Eastern Europe, the re-formatting and promotion of apprenticeships and the recruitment work undertaken by the Wool Industry Training Board. Of these solutions, employing immigrants was by far the most successful in bringing workers into the industry, while the latter two were resounding failures. In prioritising the recruitment of young, white, British men, the industry, trade unions and government missed a key opportunity to train immigrants and women to take the places of the skilled workers they so desperately sought.  相似文献

The paper considers the geographies of scientific knowledge produced around a pool dug at Long Gores, Hickling, Norfolk, England in 1953. Designed by ecologist and artist Marietta Pallis as a swimming pool and symbolic site, the pool also became a scientific experiment in landscape, through which Pallis pursued general ecological principles and specific theories on the landscape history and ecology of the Norfolk Broads. The digging of the pool coincided with the publication of research establishing the broads' artificial origin in medieval peat diggings. The paper begins by developing arguments concerning the cultural geographies of scientific knowledge. We then trace Pallis's presentation of the pool as equivalent for the broads in its origins and development, her discussion of the relationship between pool, marsh and North Sea, the connection between Pallis and local scientific culture, and the pool's place in a landscape of ecological succession. The paper concludes with further theoretical discussion, and reflection on the remains of Pallis and her reputation.  相似文献

Bison bison mandibular molars from the Late Plains Archaic kill/butchery sites of Buffalo Creek (Wyoming) and Kaplan-Hoover (Colorado) exhibit significant frequencies of dental enamel hypoplasia (DEH), a defect believed to reflect information about physiological status of individual animals. This study provides a methodology to estimate the ontogenetic and seasonal timing of DEH formation in bison dentition. Integration of these estimates with data from bison life history and grassland ecology allows inferences on age- and season-specific factors exacerbating periodic physiological declines that were recorded in the form of enamel hypoplasias. Differences between assemblages indicate regional variability in grassland conditions, with data from Buffalo Creek pointing to recurrent drought that reduced forage capacity and contributed to physiological stress in bison over two consecutive years. Seasons of physiological stress reflected in the DEH correspond to each of the three kill events at the locality, suggesting that predictability of bison behavior in this location was a critical factor in influencing the seasonal timing and location of repeated hunting episodes. Unlike Buffalo Creek, timings of stress episodes are not consistent with season of death in the Kaplan-Hoover bison assemblage, suggesting that favorable grassland conditions were the primary factor influencing timing of this large single-kill event in order to provision for the upcoming winter. DEH analysis represents a developing approach in the construction of models addressing key aspects of local grassland and bison ecology as well as offers unique insights into the hunting strategies and subsistence decisions of Late Plains Archaic foragers.  相似文献

The archaeological record of Oldowan hominins represents a diverse behavioral system. It has been suggested that exploitation of lithic resources by Oldowan hominins was simplistic and represented mostly use of local sources of stone. Here we investigate the raw material selection and transport behaviors of Oldowan hominins reflected in the stone artifact assemblages from the Kanjera South Formation, South Rachuonyo District, Kenya. Using geochemical methods (ED-XRF) artifacts are linked to primary and secondary source outcrops throughout southwestern Kenya. These data show that hominins selected raw materials for transport at frequencies that are significantly different from their availability on ancient landscapes. Furthermore, a substantial proportion of the assemblage represents transport over relatively long distances (>10 km). Our study further suggests that in the early stages of stone tool use hominins used a wide variety of raw materials and selected these materials at some distance from their eventual discard locations. Early hominin behavior may have incorporated an understanding of raw material source distributions across a more extensive landscape than has been previously documented. This supports the growing perspective that Oldowan technology represents a more complex behavioral pattern than is usually associated with the beginnings of hominin tool use.  相似文献

The persistent uncertainty on the classification of the “new” glume wheat found in Neolithic and Bronze Age sites from Greece and other European settlements might be resolved only through analysis of its ancient DNA. Tools able to discriminate among different Triticum species on the basis of scarce, very damaged DNA, are therefore essential. While current attempts concentrate on DNA fragments sequencing and comparison, in some instances PCR-based selective amplification techniques might offer a cheaper and quicker alternative. The purpose of this research was therefore the identification of species-specific primers, able to distinguish caryopses of Triticum timopheevii subsp. timopheevii from those of Triticum turgidum subsp. dicoccum. Primers and their working conditions were defined and optimized using DNA from modern accessions. The ribosomal primers ITS1 tim and ITS2 tim, and the nuclear primer acetyl-coenzyme A tim clearly discriminated the sequences of Triticum timopheevii from other species. Finally, Neolithic charred wheat grains found in the sites of Sammardenchia (Pozzuolo del Friuli, Udine) and La Marmotta (Lago di Bracciano, Roma), belonging to the “new” wheat type or to emmer, were tested with the three selected primers. However, the results were not conclusive, because the samples analysed were apparently too degraded to yield useful DNA.  相似文献

This paper explores the third-world left in Los Angeles, from 1968–1978. In it I examine the political ideology and foci of one organization for each of the major racial/ethnic groups of the time: African Americans (Black Panther Party), Chicanas/os (El Centro de Accion Social y Autonomo [CASA]), and Japanese Americans (East Wind). In addition to reclaiming this relatively unknown history, I seek to explain the differences in the various organizations by analyzing them within the context of differential racialization. I argue that the distinct nature of each organization is at least partly due to the particular racial position of each racial/ethnic group within the local racial order.  相似文献
