The questions addressed in this paper are: (i) does wage inequalityincrease with local population size, and if so, (ii) what arepossible factors behind this increase? In a cross-section analysisof Swedish local labour markets using unique full populationdata, the article shows that urban scale, i.e. size of localpopulation, has significant positive effects on wage inequality.Testing for potential explanations, labour market diversification,human capital, migration, age structure and employment are shownto be significantly associated with inequality. Given theseeffects, the article raises the question of how to understandand incorporate scale effects into models of long-term changein wage inequality.  相似文献

ABSTRACT. This paper tries to make the case for a model of political identity based on an optical metaphor, which is especially applicable to nations. Human vision can be separated into sentient object, lenses and inbuilt mental ideas. This corresponds well to identity processes in which ‘light’ from a bounded territorial referent is refracted through various lenses (ideological, material, psychological) to focus in certain ways on particular symbolic resources like genealogy, history, culture or political institutions. Distinguishing between referent, lenses and resources helps us more precisely situate many hitherto disparate problems of national identity. These include the ‘ethnic‐civic’ dilemma, the mystery of national identity before nationalism, and the relationship between local and national, and individual and collective, identities. The model also clarifies the place of universalist ideology, which currently fits poorly within the leading culturalist and materialist theories of nationalism.  相似文献

川东道是解读清代地方行政制度的典型范本。通过考察,再次证明了道由一种临时性的藩臬二司派出机构,逐渐演变成有固定辖区和治所的府以上省以下的地方行政区划和机构。因应时变、灵活性和敏感性,使得川东道在晚清被附加了很多原本不相关的职能。尽管它本身不是一个完全近代化的职官,但由于府以上省以下的空隙过大,这种中层地方机构,在中国历史上始终是需要的。  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

Optically stimulated luminescence (OSL) dating of heated/fired materials of archaeological importance from various parts of India was attempted. A single-aliquot regenerative-dose (SAR) procedure was used for palaeodose determination in the quartz grains extracted from the heated materials using the luminescence produced by blue light stimulation. In most pottery samples, the palaeodose obtained using SAR-OSL is ∼6% lower than the palaeodose measured using thermoluminescence (TL) method. Broadly, there is good agreement between the SAR-OSL and TL ages of the artefacts and their archaeologically expected ages. The results suggest that routine dating of heated/fired materials using the SAR-OSL procedure is more practicable, especially when the TL sensitivity of the quartz grains is poor and availability of datable material is limited.  相似文献

In Roman and Byzantine times, natron glass was traded throughout the known world in the form of chunks. Production centers of such raw glass, active from the 4th to 8th century AD, were identified in Egypt and Syro-Palestine. However, early Roman primary glass units remain unknown from excavation or scientific analysis. The ancient author Pliny described in 70 AD that besides Egyptian and Levantine resources, also raw materials from Italy and the Gallic and Spanish provinces were used in glass making. In this study, the primary provenance of 1st–3rd century AD natron vessel glass is investigated. The use of combined Sr and Nd isotopic analysis allows the distinguishing and characterizing of different sand raw materials used for primary glass production. The isotope data obtained from the glass samples are compared to the signatures of primary glass from known production centers in the eastern Mediterranean and a number of sand samples from the regions described by Pliny the Elder as possible sources of primary glass. Eastern Mediterranean primary glass has a Nile dominated Mediterranean Nd signature (higher than −6.0 ? Nd), while glass with a primary production location in the western Mediterranean or north-western Europe should have a different Nd signature (lower than −7.0 ? Nd). Most Roman glass has a homogeneous 87Sr/86Sr signature close to the modern sea water composition, likely caused by the (intentional) use of shell as glass raw material. In this way, strontium and neodymium isotopes now prove that Pliny's writings were correct: primary glass production was not exclusive to the Levant or Egypt in early Roman days, and factories of raw glass in the Western Roman Empire will have been at play.  相似文献

Abstract

The Ordnance Survey's Boundary Survey, carried out between 1841 and 1888, was a major undertaking which resulted in the local administrative boundaries of the whole of Great Britain being reliably mapped for the first time. This was not achieved by imposition but by the use of local knowledge of boundaries, thus making permanent a communal memory of administrative geography and rendering it globally accessible through maps. The Boundary Survey aided the reform of local government areas, a process which started during the same period and provided derived data for the burgeoning collection of statistics in the nineteenth century.  相似文献

L'information devient de plus en plus un enjeu crucial pour les institutions et acteurs engagés dans des processus territoriaux de développement. Comme la littérature sur les NTIC le démontre, l'accès a l'information concernant leur environnement global (sources de capitaux, tendances globales, débouchés, encadrement) ainsi qu'à celle concernant leurs atouts locaux et spécifiques (ressources humaines, physiques, financièrs et institutionnelles, identités, possibilités de mobilisation) fournit des indications indispensables pour faction des collectives locales engagées dans des projets de développement. Cependant, ce qui est souvent négligé c'est que le processus même par lequel cette information est produite et diffusée constitue en soi un facteur intervenant dans l'orientation que prend le développement. L'information marque les territoires concernés. Aussi est-il essentiel de construire des inforoutes permettant la participation des collectivités à la production de l'information qui les concerne. L'Atlas du Québec et de ses régions est une expérience qui vise cet objectif. Dans ce texte, nous présentons l'état d'avancement et les conclusions préliminaires de cette expérience. Information networking is a crucial issue for organizations and socio-economic actors. As the literature on development shows, information at the global level (financial perspectives, global tendencies, markets, and regulations), as well as at the local level (demographic and social characteristics; human, physical, economic, institutional, and organizational resources; specific assets; quality of life; etc.) is indispensable to local collectivities involved in development projects. Nevertheless, often overlooked is the fact that the very process by which this information is produced and disseminated has a significant effect on the direction of development. Information has an impact on the local community. There is a need for building territory information networks that allow local communities to produce the information that concerns them. This paper presents first a global survey of globalization and the effects of information highways on specific territories, and second, an experiment in progress about building a territory information network in the province of Québec, the Atlas of Québec and Its Regions.  相似文献
