Low levels of unionization in the United States have led to much attention being devoted recently to the development of new models of organizing workers. In contrast to those which dominated for most of the past half century, the models currently being embraced by many labor leaders are typically grassroots and bottom‐up in nature and call for a high level of participation by rank‐and‐file workers. The Justice for Janitors (JfJ) campaign is an example of just such a model, one which has been widely lauded for its innovativeness and success. However, whereas the campaign is often thought of as representing a highly decentralized approach to organizing because of the sensitivity it pays to local labor market conditions, the Service Employees’ International Union which developed it has recently called for a concentration of power in a small number of national union bodies. This has raised questions about the geographical scale at which power should rest within the union movement and how to develop organizing strategies which are locally sensitive yet also capable of challenging nationally and/or globally organized firms.  相似文献

Results of analyses of the photoperiod response gene (PPD-H1) and simple sequence repeats (SSRs) in modern landraces of cultivated barley were used as evidence for the mechanism of agricultural spread in Neolithic Europe. In particular, we explored the usefulness of considering adaptive genes as indicators of past selective pressures acting on crops, during their spread through Europe. In some areas, such as the Alpine region, Britain and Scandinavia, we have evidence to suggest that the adaptation of crops to certain climatic conditions may have contributed to the timing of agricultural spread. At the northern fringes of Europe, and in higher altitude locations in central Europe, the introduction of more suitably adapted cereals may have facilitated successful agriculture to trigger agricultural expansion. This research opens up the possibility of investigating other genetic adaptations to climate, which would permit a fuller evaluation of the relative contributions of climate/crop and forager/farmer interactions in the process of agricultural spread.  相似文献

This research aims to shed light on the early stages of agricultural development in Northern Africa through the analysis of the rich macro-botanical assemblages obtained from Ifri Oudadane, an Epipalaeolithic–Early Neolithic site from North-East Morocco. Results indicate the presence of domesticated plants, cereals (Hordeum vulgare, Triticum monococcum/dicoccum, Triticum durum and Triticum aestivum/durum) and pulses (Lens culinaris and Pisum sativum) in the Early Neolithic. One lentil has been dated to 7611 ± 37 cal BP representing the oldest direct date of a domesticated plant seed in Morocco and, by extension, in North Africa. Similarities in both radiocarbon dates and crop assemblages from Early Neolithic sites in Northern Morocco and the Iberian Peninsula suggest a simultaneous East to West maritime spread of agriculture along the shores of the Western Mediterranean. Wild plants were abundantly collected in both the Epipalaeolithic and the Early Neolithic periods pointing to the important role of these resources during the two periods. In addition to fruits and seeds that could have been consumed by both humans and domesticated animals, fragments of esparto grass (Stipa tenacissima) rhizomes have been identified. This is a western Mediterranean native plant that may have been used as a source of fibres for basketry.  相似文献

Between ca. 6000 BC and ca. 500 BC, barley cultivation spread across the continent of Europe from the extreme south to the extreme north. Carbon-dating would suggest that this spread, and indeed the spread of crop cultivation generally, varied in its pace, with ‘delays’ at certain points along its route. Such delays in the spread of agriculture have been explained as resulting from the slow assimilation of agricultural practices by existing indigenous human populations or as the time taken for the crops to adapt to novel climatic conditions, such as altered temperature regimes and day-lengths. A mutant form of the photoperiod response gene, Ppd-H1, causes barley to be non-responsive to long days, while the wild-type responsive form allows plants to flower in response to long days. We sequenced this gene in 65 ‘historic’ barley accessions, from the late 19th and early 20th centuries, in order to explore the potential role of environmental adaptation in the spread of agriculture. We chose to use ‘historic’ material, to complement the richer patterns in extant genetic lines, by spreading the data range in both time and space. Our ‘historic’ barley data shows a latitudinal divide in the Ppd-H1 gene similar to that found in extant lines, but with clearer geographical resolution, and extending northwards into the Arctic Circle. We discuss the implications of our results in relation to the dynamics of agricultural spread across Europe.  相似文献

ABSTRACT

We analysed assemblages of shells of land snails and small aquatic and wetland gastropods from a late Mesolithic-early Neolithic deposit in the cave of Pico Ramos (Basque Country). Shells were recovered by hand during excavation and all excavated deposit was processed by flotation, with a 250 μm mesh to recover floating material and a 1.0 mm mesh to recover the heavy fraction. The total assemblage comprised 5780 individuals (MNI) among 33 taxa, the sieved sub-assemblage having the highest proportions of these (2841 MNI in 31 taxa) and the hand-picked sub-assemblage the lowest (698 MNI in 11 taxa). Eleven taxa were absent from the flotation sub-assemblage, although the recovered MNI (2241; 39% of the total MNI) was high. The palaeoecological implications of the results are considered. Adult and large-sized juvenile shells of the edible land snail Cepaea nemoralis are abundant in the hand-picked sub-assemblage, but it is the absence of small-sized juvenile shells in the flotation and wet-sieved sub-assemblages that permits the inference that the species was collected for consumption. Wet sieving is therefore essential, both for interpreting hand-picked samples and in particular for the recovery of representative assemblages of land molluscs.  相似文献

In the nineteenth century, the coalescence of a plantation economy on the Swahili Coast provoked an upsurge in the local slave trade. Increasing numbers of enslaved workers fled inland, and, by the 1840s, some had created independent settlements. In Swahili, runaway slaves were known as watoro. Forged by men and women of diverse cultural backgrounds, watoro communities offer broad insight into how groups form and sustain themselves. This study explores how watoro settlement organization and landscape practices reflect the process of community formation. Particular attention is paid to watoro communities?? participation in regional networks and the degree to which fugitive slaves developed homogenized sociocultural norms or maintained long-term cultural plurality. This paper adopts a spatial archaeological approach centered on settlement location, housing density, and domestic architecture. Dissonances between these spatial data and artifact distributions reveal the ways in which both heterogeneity and homogeneity were expressed and experienced. Articulations and disarticulations between different evidentiary types also help to better reveal the diverse range of inter-group interactions that fugitive slaves pursued and avoided.  相似文献

Is the knowledge creation process linear or characterized by feedback relations among actors involved in the regional innovation system? How can the innovation process of ‘lagging’ regions be strengthened? What is the role and extent of inter-regional knowledge spillovers? The paper aims at providing satisfactory answers in investigating a knowledge production function framework adapted to the specific questions and which is tested on an extended sample of European regions. On the basis of the results, concrete policy measures are derived aiming at upgrading the knowledge creation capacity of European regions.  相似文献

The spread of agriculture in the Iberian Peninsula is documented from at least ca. 5600–5500BC, although botanical data are absent or very limited for large areas. Archaeobotanical information shows from the beginning an imported agrarian system with a great diversity of crops: hulled and naked wheats and barleys, legumes such as pea, lentil, fava bean, vetches and grass peas, flax and poppy. This diversity of plants with different requirements, processing and uses, implies that the first farmers quickly imported or acquired a wide range of agrarian knowledge. Regional and inter-site agrarian differences are discussed in relation to factors like ecology, culture, use of the cultivated plants and management of the risk of crop failure. The adoption of farming resulted in significant ecological, economic, dietary, and social changes for the Neolithic people of Iberia.  相似文献
