This study uses worker‐level data on industry, occupation, and place of work to explore differences in the spatial properties of production, administrative, and R&D occupation groups within industries. To measure differences, we calculate location quotients at the local labor market level and the Duranton and Overman (2005) agglomeration index for each group. We find appreciable differences in the spatial distribution of occupation groups within most manufacturing industries, with R&D occupations consistently exhibiting the highest degree of spatial concentration. Our results are consistent with the core theoretical and empirical results in the agglomeration literature.  相似文献

The Late Bronze Age–Early Iron Age midden sites of Southern Britain are amongst the richest archaeological sites in the country. The organic accumulations contain substantial quantities of animal bone, decorated ceramics, metalwork and other objects; the often deep stratigraphy allows for changes in material culture and depositional practices, food production and consumption, and shifts in social identities, to be traced through time. The well-stratified assemblages also provide useful materials for dating the deposits. This has been problematic, however, as the majority of samples produce unhelpfully broad calibrated radiocarbon dates, due to the effects of the earlier Iron Age plateau in the calibration curve, which spans c. 800–400 BC. Interpretation has relied on current understandings of the associated pottery and metalwork, which placed most midden sites somewhere between the tenth and the seventh/mid-sixth centuries cal BC (c. 1000–600/550 cal BC), but the end-date of these traditions is particularly uncertain. This article addresses this issue by presenting the results of a new dating programme for East Chisenbury in Wiltshire, southern England. Twenty-eight radiocarbon determinations were obtained and combined with the site stratigraphy in a Bayesian chronological model. The results have transformed the chronology of the site, with the end of the occupation sequence being pulled forward some one-hundred years, to the mid-to-late fifth century cal BC. These new chronologies have significant implications for our understanding of the Late Bronze Age–Early Iron Age transition and require a revision of the currently accepted chronology of post-Deverel Rimbury decorated wares in south-central England.  相似文献

There are growing concerns over current and future incarnations of routine work, based on the rise of technology and its perceived impact on skill requirements in the labour market. Drawing on Autonomist Marxist (AM) literature, the following article demonstrates how and why workers are likely to play a role in maintaining meaningful forms of work. Complimenting labour process research, which focuses on the role of worker “resistance” in the workplace, we develop a more nuanced perspective on worker agency and the human potential to create meaning through self‐governance in even the most unlikely service work encounters. Taking resilience and reworking agencies as subtle forms of “self‐valorisation”, we show how different spaces of routine work are mobilised for reproducing human connections and values in ways which act in opposition to management’s control and the evolution of unpleasant work environments.  相似文献

This paper engages selected moments in Austin Clarke’s literary journey to argue that in spite of his involvement in the development of Canadian literature (CanLit) during the 1960s and 1970s, the Canadian literary establishment continues to pay little critical attention to his contributions. This lack of recognition is specifically evident in recent writings about Canadian literature and the literary figures who spearheaded its development after Canada’s Multiculturalism policy of 1971. Canada’s becoming officially multicultural required a new narrative of Canada and new literary depictions of Canadians in their national literature, as ethnically diversified but of a single citizenship. I argue that Clarke’s legacy as a Black writer should be given more prominence in Canadian institutions because today this legacy is under threat of erasure as the number of Canadian Black voices telling mainstream stories about Black people’s experiences is evidently in decline.  相似文献

This paper looks at an ungulate irruption of wild boars that occurred in the German Democratic Republic (GDR) in the 1970s and 1980s. It argues that this hybrid phenomenon resulted from the confluence of three historically specific, intertwined factors in late 20th century Europe: first, East Germany's embrace of development ideology to remake their farms and forests; second, the simultaneous introduction of a specifically East German conservation program; and third, a new era in the longue durée of human–pig relationships. This ungulate irruption was particular to the GDR and the central European landscape of the Cold War, and only becomes visible through careful attention to the historical context and the materiality of pigs (Sus scrofa). For this reason it is possible to call these pigs new creatures of development. More broadly this paper asks both historians and social scientists to account for the temporal and spatial context when analyzing hybrid phenomena, while also raising important questions about the meaning and application of the neologism Anthropocene.  相似文献

The Registan Desert in southern Afghanistan has, like most deserts, traditionally been regarded as a barren, hostile space, devoid of human occupation other than occasional nomad campsites and an isolated 11th-century a.d. fortress. Detailed analysis of a strip of high resolution satellite imagery available through Google Earth and stretching into the Registan has revealed the presence of over 800 hitherto unrecorded archaeological sites. Many of these sites relate to water management, and predate the modern era. The water installations form networks of sites which facilitated the opportunistic exploitation of grazing following periodic rains, desert farming, travel, trade and exchange over hundreds of years, if not longer. Extrapolating from this detailed analysis, we argue that thousands of other sites have yet to be discovered in the Registan. These water management networks warrant further study in the field and protection from neglect, construction, recreational four-wheel driving, and looting.  相似文献
