Conventional migration theory suggests that rural to urban movement was a one-way once and for all movement which resulted in the severance of ties to a rural homeland and the gradual adoption of an urban lifestyle and culture. Analysis of Welsh migration to English towns in the mid-nineteenth century suggests that by no means all migrants conformed to this stereotype. Whilst Welsh migrants displayed similar characteristics to other rural-urban movers and fitted easily into an urban labour market, they were able to retain many of their rural traditions and customs in an English urban environment. They also maintained close links with Wales whilst some engaged in return migration. Although easily accepted into English urban society, the Welsh were able to live in two culture worlds for much of the nineteenth century. It is suggested that detailed longitudinal studies of other migrant groups will demonstrate diversity in the extent to which rural traditions were subsumed by urban culture in the nineteenth century.  相似文献

There is a substantial amount of common, if relatively unexplored, ground between the emergence of existentialist philosophy in France and the growth of a French jazz culture. Both Jean-Paul Sartre and Simone de Beauvoir play significant roles at the interface of these phenomena. This study investigates those roles and attempts to clarify the relationship between the 'home-grown' French philosophies and the cultural import. There are in fact two quite separate stories which have different outcomes, though there are important points of convergence. Both de Beauvoir and Sartre appropriate jazz, and for both of them the music is associated with fundamental freedoms, but where he uses it to inform and illustrate his philosophy, she derives from it a programme of action, or at least the basis for developing such a programme. Interestingly, the critical period for revealing the nexus between jazz and existentialism is not so much the post-Liberation era, but the time between the wars.  相似文献

Geomorphological mapping and analysis of soil mineralogy indicates that all summits on the Knoydart Peninsula were over‐ridden by the last ice sheet apart from Ladhar Bheinn (1020 m), where the ice attained a maximum altitude of c. 950 m. This figure is consistent with evidence from adjacent areas and suggests that the last ice sheet descended westwards across Knoydart from c. 1000 m to c. 900 at the west coast, implying that most theoretically‐based ice‐sheet models are substantially in error in this area.  相似文献
