The Poisson model typically provides a poor fit to flow data but more complex models are difficult to operationalize, especially with production or attraction constraints. Quasi- and pseudo-likelihood approaches retain the attractive computational features of the Poisson model. A shopping model example suggests the latter approach to be preferable. 相似文献

While the excavation of individual sites remains fundamental to the creation of the Palaeolithic archeological record, increasingly the focus of prehistoric research is on human adaptations to and within natural regions. Such a reorientation implies viewing sites and occupations as samples of different suites of activities in various habitats across space and time; it is dependent on the use of radiocarbon to date and relate occupation residues among sites; and it necessitates the application of methods to uncover patterns of human mobility as an integral aspect of subsistence economy, demographic arrangements and social relations. This paper contributes to the regional study of Last Glacial foragers by presenting preliminary aspects of a case study from the Asón River basin in eastern Cantabria. Assembled here are data from several recent and a few older excavations in sites distributed between the present shore of the Bay of Biscay and the uplands of the Cantabrian Cordillera. The main sites are El Otero, La Chora, La Fragua and El Perro near or at the present mouth of the river, the classic cave of El Valle in the mid-valley, and El Mirón and El Horno near the cave art loci of Covalanas, La Haza and Cullalvera in the upper valley. While the highest density of known sites in the whole drainage area occurs during the Magdalenian and Azilian periods (17–10 kya), there is evidence for substantial abandonment of the montane interior during the Mesolithic, when human settlement was concentrated around the estuary of the Asón, after which time the whole valley was repopulated in the Neolithic. 相似文献

The NeoArabia project tries to understand how environmental, social, economic and technological factors work in concert to influence settlement and abandonment along a latitudinal transect of 1200 km from UAE to southern Oman. This region was affected by wide north–south variations in the Indo-Arabian monsoon, marine upwelling activity and eustatic variations in the Mid-Holocene. On the local settlement scale, this transect is based on fine stratigraphic excavations and permits the reconstruction of the site formation processes and site catchment analysis. A large number of studies have been conducted on the Ruways-1 site, focusing on a deep stratified sequence corresponding to three millennia of occupation. These studies include on-site climate-environmental signal analysis, local palaeogeography and environmental reconstruction, reservoir effect studies, typo-technological studies, palaeoeconomic strategies, anthropological studies, sclerochronological studies and, finally, site formation processes, the understanding of which makes it possible to explain the potential and limits of the archaeological excavation. The first results confirm the richness of these archaeological archives for documenting the socio-environmental dynamics, but also the richness of its complex sedimentary structure and the importance of conducting fine and multidisciplinary excavations to answer questions about the rhythms and functions of occupations and the causalities of socio-environmental changes. 相似文献

C. P. Snow's identification of ‘two cultures’, as the literary critic F. R. Leavis pointed out in 1962, represents not an insight but a cliché, one that invites the repetition of further clichés about the origins of a divided culture, the need to bridge cultures, the emergence of a third culture, or the reality of one culture. Yet this recurrent feature of ‘two cultures’ talk does not nullify the concept's value as an object of study, if these discussions are treated as revealing points of entry into foreign historical contexts. This article adopts this approach, unearthing the liberal position that Snow developed as a novelist and critic from the 1930s, that he advanced in the form of a disciplinary lament in The Two Cultures (Snow, C.P. 1959. The two cultures and the scientific revolution. Cambridge: Cambridge University Press.), and that — to his distress — increasingly came under radical critique from the mid-1960s. Ultimately, the technocratic liberalism that Snow associated with science at mid-century came to be closer to American neo-conservatism by 1980. By tracking the fortunes of the ideological position that structured The Two Cultures, rather than lifting that text out of its moment in an attempt to engage its arguments today, this article testifies to the abiding value of contextual analysis at a moment when intellectual historians are increasingly inclined to question and even displace it. 相似文献

The Otterburn Public Inquiry (1997 and 1999) polarized opinion as to how England’s finest countryside should best be utilized. On the one hand, the Ministry of Defence sought to realize a major development in a protected area, whereas on the other, Northumberland County Council and Northumberland National Park Authority opposed the plans, arguing that conservation and recreation should take priority. This study was undertaken several years later and took a retrospective look at the saga through a recollection of personal accounts, so as to examine the impact and legacy that was borne out of this development. Semi-structured interviews were undertaken with a number of stakeholders as part of a wider project on partnership working. It was found that the Ministry of Defence used this planning dispute to affirm that defence of the realm was a greater national interest than environmental protection. The outcome of the Public Inquiry was also found to contribute towards a radical change in the way Northumberland National Park was managed. 相似文献

The study of the collapse of past societies raises many questions for the theory and practice of archaeology. Interest in
collapse extends as well into the natural sciences and environmental and sustainability policy. Despite a range of approaches
to collapse, the predominant paradigm is environmental collapse, which I argue obscures recognition of the dynamic role of
social processes that lie at the heart of human communities. These environmental discourses, together with confusion over
terminology and the concepts of collapse, have created widespread aporia about collapse and resulted in the creation of mixed
messages about complex historical and social processes. 相似文献
