The distribution of osteoarthritis of the hands was studied in 101 skeletons from archaeological sites in England. The results are similar to those found in epidemiological studies of modern populations. Osteoarthritis of the hands was more common in females than in males, and in females tended to involve a greater number of joints. The distal and proximal interphalangeal joints were commonly affected, the former more frequently than the latter, but otherwise the disease was largely confined to the first ray of the hand, centred on the trapezium. It is concluded that the pattern of osteoarthritis in the hand has probably not changed greatly over several hundred years.  相似文献

This paper seeks to place policy research undertaken in the Yorkshire and East London regions of the UK within the broader context of regional innovation system building. In particular, it attempts to draw out the releasing factors and conditions that shaped stakeholder relationships in these two EU Objective Two regions during the 1990s. This is undertaken with a view to drawing out conclusions about the extent of autonomy, institutional lock-in and compatibility within regional governance. The extent to which such EU stimulated influences are relevant to the practice of regional technological development is explored in areas which have experienced industrial restructuring.  相似文献

It is widely perceived that the degradation of China’s rangelands has accelerated since the introduction of rural reforms in the late 1970s. The popular explanation for this phenomenon has been that a ‘tragedy of the commons’ exists, as privately‐owned livestock are being grazed on ‘common’ land. Since the passing of the Rangeland Law in 1985, Chinese pastoral tenure policy has emphasized the establishment of individual household tenure as a necessary condition for improving incentives for sustainable rangeland management. Yet household tenure has yet to be effectively established in many pastoral regions. The first objective of this article is to describe pastoral tenure arrangements in northern Xinjiang‐Uygur Autonomous Region. Its second objective is to explain pastoral tenure arrangements, particularly the observed persistence of collective action. It is argued that there is no ‘tragedy of the commons’ and that it is characteristics of rangeland resources and the social environment that give rise to the particular types of institutional arrangements found.  相似文献

Little is known about the social composition of migration affecting British cities, despite the currently high political salience of this issue. This is principally because of the very limited availability of reliable city‐scale data on such migrant characteristics as occupation and income. This paper uses the Regional Migration Tables from the 1991 Census to document the migration of labour force members to and from Britain's larger conurbations, distinguishing six main Social Groups defined on the basis of occupation. It is found that all eight areas were net losers of economically active people, that all six Social Groups were generally contributing to these net losses and that, in every case except London, there was a strong positive relationship between social status and the rate of net out‐migration to the rest of Britain. This latter case suggests the need for further work, which would benefit from the more detailed migration datasets that are promised from the 2001 Census.  相似文献

From the record of dinosaurian skeletal remains it has been inferred that the origin and initial diversification of dinosaurs were rapid events, occupying an interval of about 5 million years in the Late Triassic. By contrast numerous reports of dinosauroid tracks imply that the emergence of dinosaurs was a more protracted affair extending through much of the Early and Middle Triassic. This study finds no convincing evidence of dinosaur tracks before the late Ladinian. Each of the three dinosaurian clades — Theropoda, Sauropodomorpha, Ornithischia — produced a unique track morphotype that appears to be an independent modification of the chirotherioid pattern attributed to stem-group archosaurs (thecodontian reptiles). The existence of three divergent track morphotypes is consistent with the concept of dinosaurian polyphyly but can be reconciled with the hypothesis of dinosaurian monophyly only by invoking many and rapid reversals in the locomotor anatomy of early dinosaurs. The origin of dinosaurs was not the correlate or consequence of any single event or process, be it global change, competitive replacement, or opportunism in the wake of mass extinction. Instead the origin of dinosaurs is envisaged as a series of three cladogenetic events over an interval of at least 10 million years and possibly as much as 25 million years. This scenario of dinosaurian polyphyly is as well-supported by fossil evidence as is the currently favoured view of dinosaurian monophyly.  相似文献
