In recent times, a conventional wisdom concerning the governance of cities has emerged. It revolves around the contention that policy and planning frameworks are increasingly closed off from public and democratic accountability, in order to facilitate the pursuit of efficiency over equity objectives. The implication is that 'old' styles of governance were more open and accountable, while the 'new' seek to close off debate and streamline procedures. Yet the evidence to sustain such claims seems limited; this paper situates the policies and practices of local government in the UK within a historical perspective, and develops the contention that the claimed differences between old and new styles of governance are overdrawn. Using empirical material from two UK cities, we demonstrate that there are significant continuities in the procedures and practices of policy-makers, in terms of policy objectives, styles and modes of accountability. In this sense, greater clarity is required in terms of what constitutes both the old and new modes of local governance in the British cities. 相似文献

Collagen fingerprinting of archaeological bone and teeth remains from Domuztepe,South Eastern Turkey
We applied a recently developed method of collagen peptide mass fingerprinting for taxonomic identification in faunal remains
to 111 specimens from the Neolithic site of Domuztepe in southeastern Turkey. Advances on the published technique allow us
to move beyond the key domesticated fauna (sheep, goat, pig and cattle) to include non-domesticates (deer and gazelle, as
well as humans). As the animal economy of Domuztepe was dominated by domestic sheep and goats, a large number of the samples
tested were morphologically indistinguishable sheep/goat remains. A number of samples represented elements that provide information
on age (i.e., mandibles) or sex (pelvis); thus, this represents the first major study to attempt to improve kill-off profiles
using collagen fingerprinting. We also show that the collagen extracted from dentine is equally amenable to the proposed methodology
as bone collagen. 相似文献

This paper examines the impact of animal manure on δ15N and δ13C values in a legume, Celtic Black broad bean (Vicia faba). In a field experiment, V. faba was cultivated in plots treated with farmyard manure and pure sheep manure. The results indicate that highly intensive manuring can increase δ15N values in beans, stems, leaves and pods. In comparison, manuring had a relatively small impact on δ13C values. In terms of palaeodietary reconstructions, the high δ15N values in very intensively manured beans (+3?‰) are equivalent to the trophic-level effect. Based on the experimental results, it is suggested that high δ15N values in archaeobotanical remains of V. faba may be attributable to small-scale cultivation with intensive manuring. 相似文献

This paper provides a two-phase study to compare alternative techniques for augmenting landscape scenes on geography fieldtrips. The techniques were: a pre-prepared acetate overlay; a custom-designed mobile field guide; a locative media app on a smartphone; a virtual globe on a tablet PC; a head-mounted virtual reality display, and a geo-wand style mobile app. In one field exercise the first five techniques were compared through analysis of interviews and student video diaries, combined with direct observation. This identified a particular challenge of how to direct user attention correctly to relevant information in the field of view. To explore this issue in more detail, a second field exercise deployed “Zapp”, a bespoke geo-wand-style app capable of retrieving information about distant landscape features. This was evaluated using first-person video and spatial logging of in-field interactions. This paper reflects upon the relative merits of these approaches and highlights particular challenges of using technology to mimic a human field guide in pointing out specific aspects of the landscape scene. We also explore the role of students acting as design informants and research co-participants, which can be mutually beneficial in promoting a critical appreciation of the role of technology to support learning about the landscape. 相似文献

There is a growing orthodoxy that since the global financial crisis European policy-makers and planning systems have become more dependent on inward investment and the availability of global finance to fund welfare services and projects. This process of financialisation, it is claimed, is driven by the needs of developers and investors, who are focused on maximizing returns and limiting their social and economic liabilities. Planning agencies and traditional territory-based arrangements are viewed with increasing suspicion, as standing in the way of investment and acting as a brake on much needed house-building and regeneration. However, in this paper, drawing on detailed research with investors and developers in London, we argue that there needs to be a stronger focus in academic and policy writing on the multiple, variegated, and diverse calculations and framings that private sector actors take when making investment decisions. Too often their perspectives are caricatured and/or over-simplified. We show that and imaginations of planning and regulation are complex and that many firms have realized that market success results from becoming more deeply embedded in the local political, social, and regulatory environments in which they are investing. A greater understanding of these multiple forms of calculation, in turn, opens up opportunities for the maintenance and/or implementation of more effective forms of territorially-based soft and hard regulation. The paper concludes by outlining a broader research agenda for planning and urban studies. 相似文献

Pole, M., December, 2008. The record of Araucariaceae macrofossils in New Zealand. Alcheringa 32, 405–426. ISSN 0311-5518. The Araucariaceae have a long record in New Zealand, extending back to the Jurassic at least, and Araucaria extends back to at least the Late Cretaceous. This paper reviews the macrofossil record of the family and presents new information based largely on the leaf cuticle record. Agathis, which is the only genus of the family currently growing in New Zealand, has no record before the Cenozoic. All specimens previously identified from pre-Cenozoic strata clearly belong to other taxa or do not show characteristic features of the genus. Araucariaceae macrofossils are virtually ubiquitous in the Cretaceous assemblages of New Zealand but are conspicuous by their absence or rarity in Palaeocene deposits. Their demise may be an expression of events at the Cretaceous–Palaeogene boundary. 相似文献
